Title: Fire extinguishing equipment-triggering system - has spring loaded arm on hydraulic cylinder linkage actuated by thermal fuses
Inventor: EIBL WOLFGANG ING GRAD
IPC: A62C3/07
Filed: 1979-11-10
Abstract: The fire extinguisher (1) is installed inside the engine room of a crane and is actuated by the swinging movement of an arm (2) with one end hinged on a fixed bracket (3) and the other end connected to the piston rod (6) of a hydraulic cylinder (5). The arm (2) is loaded in the downward swinging direction by a spring (4). The arm (2) is also connected by a link element (7) to a valve (8) controlling the fuel circuit of the Diesel engine. The hydraulic cylinder is kept under pressure by a non-inflammable medium in a circuit (10). The pressure is produced by hand pump (11) via a non return valve (13). In case of a fire the thermal fuse (16) melts, medium escapes from the circuit (10), and the arm (2) swings downwards, shutting off fuel supply in piping (9) by valve (8) and actuating fire extinguisher (1).

Title: Monostable rotary armature system - uses soft magnetic armature with inserted permanent magnet having pole which is adjacent armature pole
Inventor: ROSE GUENTHER
IPC: H01F7/14
Filed: 1980-02-16
Abstract: The system is used in electromagnetic drives and has a rotatable armature between two electromagnetically excitable poles. In such systems it is desirable to hold the armature in defined rest position, while it can be moved into operational position by an electromagnetic force. After the latter has ceased to operate, the armature returns back to its rest position. The soft magnetic rotary armature (6) is fitted with at least one inserted permanent magnet (7), whose pole is arranged directly next to a soft magnetic pole (14) of the rotary armature. If the armature is of rotation symmetrical type, two permanent magnets (7,7') are used, in NS-NS polarity direction, with the interposition of a soft magnetic armature section (15). Stops (11,11') may be used to limit the armature angle of rotation.
Patent DE-3010109-A1 (DE)
IPC: G07F17/14
Filed: 1980-03-15
Abstract: Time identity cards (21) are dispensed with a time identity-card dispensing apparatus (22) adjacent to the entry-barrier checking apparatus. They are issued after a coded and person-identifying data carrier has been inserted. A treatment-stay application confirmation (23) is inserted into the slot (24) of the time identity-card dispensing apparatus (22). The treatment-stay application confirmation (23) is retained and checked for authenticity and period of validity. The issue of the time identity card (21) thereafter takes place through the dispensing slot (25) of the dispensing apparatus (22). The components of the machine (3) are a plurality of dispensing shafts (7) and a timer (8) which assigns the dispensing shafts successively in a time-dependent manner to the dispensing orifice (9) of the machine (3). After the insertion of the time identity card (21), the coding of which represents a part credit amount of the total sum to be paid, into the insertion slot (5), the missing difference amount is to be introduced into the insertion slot (4), after which the machine (3) returns a coded checking element (6) and the time identity card. The checking element (6), after being extracted from the dispensing orifice, is inserted into the entry-barrier machine (11), whereupon the latter releases the turnstile (13) for passage. This use-time checking system is designed so that, whilst being of a design largely proof against evasion and preventing misuse, it makes it possible to do away with a central check of the authorising acquisition of identity cards containing data. <IMAGE>

Patent DE-3015274-A1 (DE)
Title: Fault location signal evaluation circuit - adds scrambled command portion bit for bit in modulo 2 mode
Inventor: POSPISCHIL REGINHARD DIPL ING
IPC: H04B17/40
Filed: 1980-04-21
Abstract: The appts. is used to convert a standard multi-channel high bi-trate transmitter/receiver into a self-checking and fault tracing circuit. During the resting phase, the message signals are replaced by a channel location fault tracing word (OSS) sent out by a locating controller (OG) which also produces clock pulses (TS). These signals are also applied to the three other channels at switching circuits (SE1-4). The inserted location tracing words pass through a test loop which is initiated at a loop connecting circuit (SF1) and closed at another such circuit (SF2), and are finally received in the location controller receiving lines (OS 1 E to OS 4E) together with the clock pulses (T1E to T4E). In the receiving branch of the telecommunication terminal the command word is descrambled in a unit (DSC). When the test loop is active, the unscrambled command word i in fact scrambled in the descrambling unit (DSC). The test word generated in the location controller is combined with that received via the descrambler unit in exclusive-OR gates whose outputs must remain at logic zero until a fault in one of the channel send/receive loop circuits occurs. This can be channel-individual located and displayed.

Title: Crystallisation-heat storage device, especially for warming beer
Inventor: IMHOF ERNST
IPC: A47J39/02
Filed: 1981-03-07
Abstract: The present invention describes a novel possibility of warming, to a state where they are ready to drink, beverages (primarily beer) which, when dispensed, are heavily chilled. Instead of the metal sleeves used hitherto for this purpose, which are filled with warm water, an approximately similarly shaped crystallisation-heat storage device (Figure 1) is proposed which offers various very attractive advantages for this task. 1) "Charged with heat" it can be stored cold for any length of time, to give off its latent heat only when required. 2) "Freshly charged" it can first transfer its "sensible" heat quite conventionally into the first glass of beer, while the following, second glass is warmed by the heat storage device latent heat which the customer can release himself. This heat storage device is represented by a thin-walled, cartridge-shaped metal cylinder which on one end face is sealed by a pretensioned silicone-rubber disc. The charge of sodium acetate trihydrate NaC2H3O2 . 3H2O turns liquid when heated above approximately +58 DEG C and remains so even when cooled below this range. Upon recrystallisation, which can be triggered at will, by contact with isomorphic crystals via the needle (Figure 1/25), the previously introduced heat, stored in latent form, is liberated again. Recharging of the cartridges can be carried out in a waterbath or in another suitable manner. <IMAGE>
