Title: Vending machine for chilled freshly pressed orange juice - which automatically discards empty peel to avoid bitter flavour
IPC: A23N1/02
Filed: 1981-01-22
Abstract: The pressing cycle includes the following automatic sequence:-(1) a single orange is released from a batch in a storage hopper to fall into a pocket formed by a pair of coaxial hinged 'hands' at the ends of telescopic arms. (2) The hands grip the orange from opposite sides, leaving a diametral gap through which a cutter separates the orange into two halves, each half remaining gripped by its hand. (3) The arms retract to allow the cutter to be replaced by rotary press heads. The arms advance to squeeze the halves on the press heads. (4) Juice, pulp and pips fall into a centrifuge which delivers clarified juice into a reservoir which is refrigerated. (5) The hands are retracted to discharge empty peel hemispheres into a grinder which also receives waste from the centrifuge. (6) The hands are washed and returned to the cycle restart position. The sequence continues to deliver juice until the reservoir is full and is then stopped until a restart low level is reached. The operation is entirely automatic. The peel is not crushed into the juice which protects it from bitter flavours.

Title: Portable microprocessor for classifying bridge players in tournament - has starting information loaded into memory from keyboard for processing results from each game
IPC: G06F19/00
Filed: 1981-03-30
Abstract: An alphanumeric keyboard (1) connected to a microprocessor (2) allows an operator to enter data into memory assemblies (4,5). One memory stores the tournament starting information such as numbers of tables in each section and the numbers of players in each position. A memory selector (3) provides an initial position set of data for one of the memories (4) for the start of the tournament. The scores for each game are entered via the keyboard and a decoder (6) transmits the processed information in plain language to a display or printer (7). Simultaneously the initial position data is transmitted to an averaging counter (8) and then into a memory table (9). A progression selector (10) activates the initial position sections of memory ready for the next sets of results.
Patent FR-2503526-A1 (FR)
Inventor: DOUTEY MAURICE
IPC: H01L25/11
Filed: 1981-04-03
Abstract: The housing for mounting semiconductor components contains a connection grid comprising a plurality of terminal lugs (21, 22, 23). The upper region of each of these lugs is designed to be bent in order to lock nuts which are arranged on the top of the housing. Holes (31, 32, 33) are situated opposite the threaded holes of said nuts. In the lower region of the lugs there are bent lamellae (26, 27, 30) and bent plates (25, 28). The plates are designed to act as supports for the semiconductor components. Certain lamellae (27, 30) lead to the vicinity of the various semiconductor terminals, while one lamella (26) serves as carrier for L-shaped terminal elements (44, 45) whose one limb serves as external terminal and whose other limb serves for connection to certain terminals of the semiconductor component. A particular field of application of the mounting housing is in medium-power component bridge circuits.

Title: Motor race finish electronic timing installation - involves mobile transmitters triggered by reference signal from fixed finishing line antenna
Inventor: SCHAFFER RUDOLF
IPC: G08G1/017
Filed: 1981-10-02
Abstract: The fixed antenna (3) may be a cable across the track for receiving the identifying signals from each vehicle-borne appts. (2).
