201	Secure latch for double-wall structure	US491521	1995-06-16	US5584517A	1996-12-17	Robert A. Simnacher; Daniel J. Banyas
An improved secure latch for a fixture having a door with a double-wall structure, including an endwall with an exit port and an inner sidewall with a slot near the endwall and parallel thereto. An entry port of a facing member and an orifice of a tongue, slidably receivable through the slot, of a latch attached to the facing member are aligned with the exit port as the door is in a closed configuration such that a bolt of a lock installed in the door is slidable therethrough as the bolt is displaced between a locked configuration and an unlocked configuration. The secure latch is adapted to retain the door in a closed configuration as the bolt is in a locked configuration even though the facing member may be forced clear of the bolt. Further, the secure latch prevents the lock from being sprung open without inflicting severe and visible damage to the door and/or the facing member. A modified embodiment provides the endwall without the exit port and the facing member without the entry port. The locked configuration includes extending the bolt through the orifice of the latch.
202	Electronic combination lock with high security features	US236010	1994-05-02	US5517184A	1996-05-14	J. Clayton Miller; Gerald L. Dawson; Daniel L. Thompson; Michael P. Harvey
An electronic combination lock includes a combination lock having a dial with no markings thereon. Rotation of the dial drives a generator which produces electrical pulses. The voltage pulses serves as a power source for the electronics of the lock. The lock also includes a security feature to disable the lock if the combination dial is stopped between dial rotations for a period of time which indicates dailing by an automatic dialer.
203	Combination lock with arrangement for defeating automatic dialer	US255313	1994-06-07	US5473921A	1995-12-12	Ilan Goldman
A circular rotating member, having an outer peripheral surface, is rotatably mounted in a ring member. The rotating member includes an elongated central slot and four peripheral slots extending inwardly from the peripheral surface of the rotating member and spaced at 90 degrees from each other. The key of the combination lock extends into the central elongated slot, and a ball bearing is carried in each of the peripheral slots of the rotating member. The inner surface of the ring member is substantially identical to the outer peripheral surface of the rotating member but the inner surface of the ring member includes, additionally, two cut-outs. Thus, when the ring member is driven to rotate at a high speed by an automatic dialer, the ball bearing will be driven by centrifugal force into the cut-out whereby to prevent further rotation of the dial to thereby block the lock.
204	Entry protection device for combination dial locks	US885596	1992-05-19	US5257520A	1993-11-02	J. Clayton Miller
An entry protection device for use with combination dial locks includes a flange annulus which permits removable attachment to a combination dial. The flanges are disposed between the rear surface of the combination dial and the facing surface of a security container to prevent unauthorized removal of the entry protection device. The entry protection device includes indicators to permit detection of surreptitious entry by penetration or removal of the device. The entry protection device includes an anti-rotation feature which prevents continuous 360.degree. rotation of a combination knob by an automatic dialing machine but allows hand manipulation of the dial by a user. The device may be combined with a combination dial having an irregularly shaped dial knob surface to prevent engagement of the dial knob by an automatic dialing machine.
205	Secure code operated device	US233029	1988-08-16	US5159333A	1992-10-27	Raymond A. Wolski
A secure coding device is presented that requires a multi-bit binary code to rotate a locking cam to an unlock position. The device is secure against unauthorized human intervention because it does not provide information to an attempted intervenor which can be used to further attempt to gain access to the system.
206	Flush combination lock	US868691	1986-05-30	US4683738A	1987-08-04	Nathan L. Berkowitz
The combination lock has a case which contains the lock mechanism including permutation discs. The case is mounted behind and protected by the locker door. An escutcheon plate is mounted on the front of the door with a rotary dial mounted therein. The rim of the dial has indicia to brought into registry with the fixed index on the escutcheon. The dial rim slopes at about 45.degree. to the rotational axis of the dial and this slope deflects lateral blows or impacts. The center of the dial is recessed and has pads engageable by the user to facilitate turning the dial.
207	Combination lock monitoring system	US337238	1982-01-06	US4453390A	1984-06-12	Peter G. Moritz; Simon L. Harders
A combination lock monitoring system for recognizing and indicating electronically the condition of operation of the lock, the recognition being achieved by photo sensitive means responding to the light reflecting quality of areas on the lock bolt mechanism, the lock drop arm and a combination wheel of the combination lock, the electronic circuit responding through a binary code to the condition of the photo sensitive means, and the indication including a visual display.
208	Combination locks	US824986	1977-08-15	US4197726A	1980-04-15	Tim M. Uyeda
A dial for a combination lock extends through a disc mounted on the housing for supporting the dial. A pair of interchangeable members, one being used at a time, are used in conjunction with the dial. The first interchangeable member is a spacer mounted on the disc between the dial and the disc for spacing the dial from the disc and covering a portion of the disc. The second interchangeable member is a cover mounted over the disc. The cover has a window through which the dial can be seen. The window includes a lens with thin plates therein for directing light from the dial in a certain path so that the dial can only be seen from one position. The cover has members for securing the lens in the window so that it is not easily removed therefrom.
209	Punch-thru lock assembly	US844537	1977-10-25	US4123925A	1978-11-07	Joseph F. Nemec, Jr.
A punch-thru lock assembly for use on safes and vaults and effective to prevent the forceful removal of the cover from the lock so as to preclude unauthorized access from being gained to the inside mechanisms of the lock while the door of the safe or vault is in its closed and locked position. The punch-thru lock assembly includes a spindle having a cam wheel secured thereto by means of a key whereby the cam wheel rotates in unison with the spindle but the key is capable of being defeated so as to free the cam wheel from engagement with the spindle. The lock assembly also includes a cover which is intentionally provided with a weakened portion through which an end of the spindle may be made to pass, when the latter is forcefully removed from the lock assembly being pushed inwardly.
210	Eccentric-ring combination lock	US3628355D	1970-09-09	US3628355A	1971-12-21	ZANGRANDO ROY A
A combination lock having an outer operating dial connected through a dial shaft with an internal coding mechanism comprising a number of rotatable eccentric code rings placed successively radially about each other in the same plane and connected with the dial shaft. Rotation of the dial according to a coded combination effects rotation of the rings to positions in which the widest portions are in radial alignment. The eccentricity of the mechanism is then maximum with the outer ring at a maximum distance from the shaft. At this point contact is made with a separate unlocking or output mechanism to trigger it into locking connection with the dial shaft for unlocking operation by the dial.
