Title: Lock and key for waiters - with identification by infrared diodes and infrared detectors across holes in key wards
Inventor: DEWALD WILHELM
IPC: G07F7/02
Filed: 1979-06-22
Abstract: A lock and key for use by waiters in large establishments to gain access to dispensers which charge the extracted article to the individual waiter uses a flat key pref. made of polycarbonate which has in the centre of the ward a copper foil, bonded to a self-adhesive plastic foil. This copper foil is impermeable for infrared rays but two rows of holes, each with up to 12 holes, allow a coded identification. The lock itself is a block of plastics, with a slot for the key and with cross bores to correspond to the rows in the copper foil of the keys. One end of each cross bore carries an infrared diode and the other an infrared silicon transistor as the radiation detector. This creates a system which cannot be counterfeited and is less bulky than one using reed relays.

Title: Credit card validity checker - has inputs for card scanning linked to processor with connections to memory and display unit
Inventor: BEUST JUERGEN
IPC: G07F7/08
Filed: 1979-07-21
Abstract: Protection against the misuse of credit cards or cheque cards is ensured by a verifier which compares the number of the presented card with a stored list of invalid cards. Rapid checking with a relatively simple unit is achieved when the list is stored in a dynamic memory, such as a floppy disc which can be readily updated. The sectors of the disc are then arranged according to card division characters to reduce the search, as well as may contain data concerning the card holder. The input side may comprise units (1-4) where the individual card can be inserted for scanning optical character reading or be sensed by an electronic stylus readout. The derived code train is fed to the processor (5) for comparison with data stored in a memory (6) and also featuring a data transfer interface (7). The comparison result is displayed by an indicator (8).

Title: Pond for algae culture of settling type - having water feed through tipping pan to generate waves which slope over weir removing suspended algae and leaving heavy type
Inventor: WAGENER KLAUS PROF DR
IPC: A01G33/02
Filed: 1979-09-11
Abstract: Algae which settle out of a suspension are kept free of the lighter more easily suspended variety by creating waves in the culture pond. The water is added via a pan which then tilts and drops the water into the pond. The falling water creates waves which wash over a weir at the other side of the pond. The wave motion carries out suspended algae and serves to agitate the pond. The settling type algae collect on the base and are retained within the pond. System is for use on algae cultures which can subsequently be used as raw materials for methane and/or methanol production. It provides a simple, effective process which has low energy usage to keep algae cultures in settling ponds pure and free of lighter strains.

Title: Blindstitch sewing machine - has phased lifting of fabric holder so that fabric advance does not mark fabric or stitching
Inventor: JAGIELSKI JOHANNES
IPC: D05B1/24
Filed: 1980-04-22
Abstract: Fabric holder is forcibly lifted by the fabric bender when the fabric advance is active on the blindstitch sewing machine. The needle swing shaft gives the drive to lift the fabric holder. There is a lever (I) ranging at least partially at an upwards angle on the pivoting axis of the fabric holder, and a further lever (II) on the needle swing shaft. When the lever (II) on the swing shaft swings down, it bears against the fabric holder pivot axis to raise the fabric holder. One fabric holder is held up for longer than the other holder, as its lever is used to trip in turn the lever of the other holder. There is an adjustment screw between the levers of the two fabric holders. The fabric holder which is raised longer, acts with the fabric bender lying on the greater number of fabric layers. The system ensures that the fabric and the stitching are not affected by the fabric advance mechanism in operation.
Patent DE-3018869-A1 (DE)
Inventor: BICKEL HANSJOERG
IPC: B23F5/06
Filed: 1980-05-16
Abstract: With this gear-grinding machine, profile-corrected and longitudinally corrected tooth flanks can be generated on a workpiece (W). The corrections required for this are taken on the one hand from a longitudinal-correction transducer (60) and on the other hand from a profile-correction transducer (80). Mechanically generated signals are converted into electric signals in these correction transducers and are transmitted via corresponding lines (76, 92) to a control device (78), from which actuating transducers (104) can be activated. Starting from these actuating transducers, actuators (100) in a hydraulic system bring about a displacement of a grinding head (38) which carries a grinding wheel (40) machining the tooth flank. In particular the appropriate cutting feed and desired transmission ratios between correction transducer and the corresponding actuators (100) can be preselected at a control panel (112) and an associated indicating unit (114). <IMAGE>
Patent DE-3020508-A1 (DE)
Title: Sonar equipment for vessel measuring velocity distribution - sounds depth vertically and at angle and computes effective geometric angle
Inventor: FAHRENTHOLZ SIEGFRIED R J DIPL
IPC: G01S7/52
Filed: 1980-05-30
Abstract: A sonar device continuously measures the bending of a sound wave. The process is based on the principle that the speed of sound propagated through water is a function of temp. and of the salt content. The measuring process enables the velocity distribution between the surface of the water and the bottom of the sea and hence the reflection of the sound wave to be determined. This is achieved without submerging a probe or reducing the speed of the vessel. The depth of the water is first sounded vertically and the results stored. This process is repeated in one or more directions at an angle to the vertical. Depending on the movement of the vessel, the result of the vertical sounding is compared with the sounding of a given angle instantaneously. The effective geometrical angle is first established for the angular sounding.

Title: WC with metered washing flushing
Inventor: BRINK HEINRICH DIPL ING
IPC: E03D5/01
Filed: 1981-01-22
Abstract: The WC, according to the invention, which is equipped with a water-metering flushing device, is particularly suitable for land-bound vehicles and aeroplanes. The invention relates to a WC base which is equipped with an odour seal and pedal-actuated flushing and through which, without using energy, such as electrical power or compressed air, and a special control means, precise flushing can be carried out with a minimum water requirement. A non-return valve is provided in the inflow pipe of a cylinder articulated on the WC base. Furthermore, a valve which opens with an excess cylinder pressure and a nozzle which projects into the upper edge of the WC base are arranged in the cylinder/WC base connection line. The lever force of the pedal acting on the piston puts the cylinder water filling under excess pressure which closes the inlet non-return valve and opens the outlet excess pressure valve. The water shoots directed tangentially downwards, into the upper part of the WC base and flows in a helically rotating manner to the outlet, the rate of rotation increasing as the cross-section of the WC bowl narrows.

Title: Program sequence control in a multi-program language-teaching system
Inventor: MATJASIC JOSEF
IPC: G09B19/06
Filed: 1981-03-10
Abstract: According to the teaching of the main application P 3102300.2, the program sequence control in a multi-program language-teaching system is effected in such a manner that the individual teaching programs can be both selected from the student's location and allocated to the students from the teacher's desk, distribution by the teacher always having priority due to a suitable combination of the control switching signals. The subject-matter of the invention going beyond this is, inter alia, that the program allocation selected by the teacher for the various students during the current teaching session is stored and thus also retained when the teacher temporarily interrupts this program allocation in order to insert individual instruction of individual or a number of students. Having regard to the central release of the student's cassettes by means of the "EJECT" key in accordance with the main application, it is also proposed also to provide for releasing an individual student's cassette while simultaneously operating the corresponding student's location key. Finally, the further proposal of the invention is also for triggering an individual tape rewind of a student's cassette with priority from the teacher's desk by operating the central tape rewind key in the teacher's desk in stop mode at the same time as the student's location key.
