Title: Anti theft belt for luggage - has tongue on belt held in slot in lock housing with tensioning reel actuated by hand grip
IPC: A45F5/10
Filed: 1981-02-27
Abstract: The locking belt (9) encircles the luggage and is used with a closure (1) locked by a key. The belt is rolled up on an axle (2) inside the lock and a pawl in the lock worked by the exterior grip (3) allows the maximum tightening of the belt about the luggage. Belt closure is achieved by a tongue (4), integral to the belt, fitting and locking into the female housing (5), while key operation ensures both the holding of the tongue and the immobility of the axle so that the belt cannot be released.
Patent FR-2477031-A1 (FR)
Title: Air filter for ventilation system has pleated sheet element - protected from gusts of wind by baffle on air inlet side
Inventor: SCHIRK KARL-HEINZ
IPC: F24F13/28
Filed: 1981-02-26
Abstract: The filter is of the type having an element of concertina- pleated filter sheet. The element is pref. of annular cross-section with the pleats extending axially from end to end of the element. Each end of the element has a cover plate fixed to the sheet with adhesive cement into which the sheet is set. On the air inlet side of the element a baffle plate is also fixed to the cover plate by setting in the same cement. This protects against the shearing action of gusts of wind the filter sheet at the plane of emergence from the cement.

Title: Starting up compressor which recycles vapour to evaporator - using live steam to turn over machine before switching on drive motor
Inventor: PRADINES ERIC
IPC: A23C1/12
Filed: 1981-03-27
Abstract: Compressor is turned over by live steam being passed into the suction pipe. The steam being passed through and out of the compressor. The live steam can be injected via a thermo compressor or ejector pump which entrains vapour drawn from the evaporator. Any steam discharged in excess of that which can be recycled to the evaporator is pref. piped to a condenser. Alternatively, the excess steam can be directed to a condensing heat exchanger in the heating circuit of the evaporator. Such a condensing heat exchanger can be located in a second evaporator. Method is used to overcome inertia of moving parts in a compressor recycling vapour to an evaporator, e.g. for the prodn. of condensed milk etc. This turnover from standstill immediately precedes switching on the electric motor driving the compressor. Since the drive motor applies driving torque only when the compressor has been brought up to, or close to operating speed, a much lower-powered motor and lighter transmission coupling(s) can be used than when the motor had to start the machine from standstill.

Title: Dishwashing machine with ventilation and drying system - uses external air drawn through filter and heated before drying dishes, and labyrinth condenser on air outlet
Inventor: DEISS ULRICH
IPC: A47L15/48
Filed: 1981-10-06
Abstract: The dishwashing machine has a fresh air ventilation system which draws air from outside the machine, across the heater, and into the machine interior to dry the dishes. Air is drawn in by a fan fitted in the lower part of the machine enclosure (21). The air is drawn through a filter and directed over a heating element before being delivered along a tube to the outlet nozzle (22) in the machine wall. The nozzle is shaped to disperse the air round the interior of the machine (11). The water laden air is exhausted through an outlet hole (24) in the wall then through a labyrinth condenser fitted between the dishwasher bowl and the enclosing panels. Filtration of both the incoming air and the outgoing, water vapour laden air ensures clean air inside the machine and dry outflowing air.

IPC: H04B10/213
Filed: 1982-12-21
Abstract: The present invention relates to an optical quadripole which can be used especially as a coupler for access to an optical serial bus. It comprises four arms A, B, C, D each having means for receiving and/or for transmitting light rays 2 and a return device 3 having two operational states, a first state where it is reflecting and is capable of returning the light between the arm A and the arm B on the one hand, and between the arm C and the arm D on the other hand, and a second state where it allows light to pass between the arm A and the arm D on the one hand, and between the arm B and the arm C on the other hand. The four arms A, B, C, D are coplanar and each arm forms an angle of 90 DEG with the adjacent arms. A coupler for access to a serial bus is produced by connecting the arm A to an optical line L, the arm B to a detector Ri, the arm C to an emitter Ei and by arranging the arm D so that it returns the amplified light signals to a section downstream of the optical line L. A line L'i connects the detector Ri and the emitter Ei in order to produce the said amplified signals.
