An identifier element construction for identifying persons, articles and domestic animals in poor illumination conditions comprises a phosphorescent or luminescent material body coupled to a plate-like element, for example for a domestic animal or a supporting element to be applied to an underwater equipment.

The construction can be provided with a "negative" wording, adapted to be read on the luminescent surface even in a full darkness condition.

System zur Rückgabe eines verlorenen Schlüssels bzw. Schlüsselbundes 2 mit einem Schlüsselanhänger 1, der mit einer Codierung zur Identifizierung des Eigentümers des Schlüsselanhängers 1 durch eine Schlüsselzentrale 5 versehen ist, wobei die Codierung zur Identifizierung des Eigentümers des Schlüsselanhängers 1 eine maschinell lesbare Codierung, insbesondere ein Strichcode 3, vorgesehen ist.

A multi-function handheld device includes a casing unit 10, a torch unit 30, a mirror piece 40, a magnifying lens piece 50, a thermometer 60, and a compass 70. The casing unit 10 includes lower and upper casing members 11, 12. Rear casing parts 112, 122 of the casing members 11, 12 cooperatively confine an air inlet 161. The rear casing part 112 of the lower casing member 11 is further formed with an air outlet 162 to permit generation of a whistling sound output. Front casing parts 113, 123 of the casing members 11, 12 are spaced apart so as to define a receiving slit 171 for mounting the mirror and lens pieces 40, 50 pivotally therein. The casing unit 10 further has receiving cavities 192, 191 for mounting the thermometer 60 and the compass 70 respectively therein. The torch unit 30 is mounted in torch receiving chamber 1231 of the front casing part 123 of the upper casing member 12, and includes a press member 135 that is operable to make electrical connection between a lamp member 32 and a battery set 31.

Based on a conventional key ring with its corresponding ring, or any other closure (1) and ornamental head (2), the inventions implies said head (2) bearing a currency conversion table, such as from Euros to Pesetas, or any currency, suitably printed on head (2), and in addition to said conversion table (3) a housing (7) which allows attachment and removal of a coin, token or the like (8), for which purpose housing (7) is provided with two side arms (6) which may be elastically deformed and which slightly strangle the opening of housing (7), retaining the coin, token or the like inside it in a stable position.

Le boîtier selon l'invention est formé de deux demi-coques identiques à rebords (4) encliquetables l'un sur l'autre. Chaque demi-coque (1) comprend un rebord périphérique d'obturation (4) muni d'au moins deux tenons (5, 6) à feuillure (13, 14), diamétralement opposés et prolongeant le rebord (4). Deux demi-mortaises (7, 8) sont creusées dans des parties diamétralement opposées de rebord entre les tenons (5, 6) successifs. On peut ainsi réaliser deux demi-coques identiques.

A single cell flashlight which comprises a barrel (76), a tailcap (78), a head assembly (77), and a semi-permanently mounted reflector (80), lens (26A) and o-ring (79) within the head assembly; which may be switched on and off by rotation of the head assembly with respect to the barrel; which may be focused upon further rotation of the head assembly with respect to the barrel; which may be used as a source of unfocused, substantially spherical illumination by removal of the head assembly from the barrel; which may be provided with a lanyard or a key ring holder positioned near the head end of the flashlight to provide for simultaneous illumination of a lock as well as its key with one-hand operation of the flashlight; and which is provided with a special tailcap insert (64A) for that a single-cell flashlight employing batteries of a "AAA", "AAAA" or special size batteries.

A device which will act efficiently as a float for any article (e.g. keys, mobile telephone, wallet) attached thereto when dropped into water comprises an inflatable bag (14') of substantially waterproof and air impervious material, a container (12) of compressed gas, and trigger means (16,30,32) associated with the container (12) and operable upon immersion of the device in water to open the container (12) and allow gas from the container (14') to inflate the bag (14). The trigger means comprises a valve (16) mounted on the container (12) and connecting the container to the inflatable bag (14'), retainer means (64) operative to hold the valve (16) in a closed condition, and water reactive means (66) which, upon contact with water, serves to release the retainer means (64) and allow the valve to open, e.g. under spring bias. The water reactive means may comprise a band of material (66), at least part of which is water reactive. The bag (14'), the container (12) and the trigger means are housed in a casing (10) and means (37) are provided, preferably integrally on the container (12), for attachment of the device to another article.

An illumination device (50) is mounted inside the inflatable bag (14'). This preferably includes a light emitting diode (LED) (52) powered by at least one battery (54), the latter being automatically connected to the LED upon inflation of the bag by withdrawal of an intervening strip of insulating material.
