Patent DE-2607016-A1 (DE)
Title: Telephone amplifier for both voice and call bell - has analog delay line to prevent acoustic feedback and transistor bell signal amplifier
Inventor: LAU MANFRED
IPC: H04M9/08
Filed: 1976-02-19
Abstract: The telephone amplifier is used for amplification of both the voice and the call bell and exhibits no feedback effects. An analog delay line is connected somewhere between the loudspeaker and the input in order to prevent acoustic feedback. A transistor circuit is used to amplify the bell signal. This circuit draws no current until the bell rings. An external signal generator can be connected to the output of this circuit. The transistor circuit may be replaced by CMOS gates also drawing no current in the rest state.

Title: Drive mechanism for conveyor belt of agricultural machine - consists of ratchet wheel driven by two ratchets fixed to rocker arms
Inventor: KRONE BERNARD
IPC: A01D90/10
Filed: 1976-02-26
Abstract: The drive mechanism for operating a conveyor belt of an agricultural implement consists of a ratchet arrangement fixed to the shaft of the conveyor belt. The ratchet wheel is driven by two ratchets fixed to to-and-fro moving rocker arms. One ratchet is driven by a chain, and the other ratchet by a piston rod. The other ratchet can be brought manually in and out of contact to couple one end of the chain and piston rod together. The contact area of the ratchets with the drive cogs can be altered by means of a pull-cable or by a linkage with the discharge roller. A control pulley serves to alter the contact area of one ratchet. A rocker arm adjust that of the other ratchet.

Title: Cigarette vending machine with flashing lamp - guides coin to actuate switch closing indicator lamp circuit to draw attention to new brand
Inventor: MANKE WERNER
IPC: G07F9/02
Filed: 1976-03-23
Abstract: A cigarette vending machine has a display lamp over one of the delivery drawers that flashes when the coins are inserted. This facility attracts a customer's attention to a new brand of cigarette. Typically, the machine (10) has a number of different brands (13) displayed behind a transparent cover (12). Coins are inserted through a slot (17) and the appropriate delivery drawer (11) pulled to extract the packet. The first coin inserted activates a miniature switch that closes a circuit across either a multivibrator or a motor-driven cam timer. The multivibrator or the cam timer causes periodic excitation of the display lamp (15).

Title: Detector for fissionable material long objects esp. fuel rods - includes layer which selectively attenuates source neutrons
Inventor: FILSS PETER DR
IPC: G21C17/06
Filed: 1976-03-31
Abstract: A device for the non-destructive determination of thermally fissionable nuclides is intended for use on long objects, such as fuel elements. The low-energy neutron source, the irradiation range and the detector range are all mutually spatially sepd. In the detector range the source neutrons and the fission neutrons which are used for detecting the fissionable material first have to pass through a hydrogen-rich, neutron-transporting layer of critical thickness; this layer either itself contains thermal neutron absorber or is separated by a concentrated absorption layer for thermal neutrons from the moderator, which is free from additional neutron absorbers and contains the neutron detectors. Used for new or irradiated fuel, esp. for fuel elements of water reactors and breeder reactors. The device is effective with large, esp. long fuel elements and rods.

Title: Ironing table stacker - with plate scoop to slide under ironed fabric for removal
Inventor: BAECKMANN REINHARD ING GRAD
IPC: D06F71/38
Filed: 1977-02-02
Abstract: Gripping mechanism for a stacking unit for an ironing table in garment mfr. has >=1 reciprocating drive. A relatively thin plate, in the form of a flat scoop, is attached at one end by an overhung mounting to the drive to lie at a slight angle to the upper surface of the ironing table, when the drive is in the start position.

Title: Electrochemical corrosion prevention on solar heat collectors - by embedding absorber in collector casing with plastic foam
Inventor: RITTMAYER GERHARD DIPL PHYS DR
IPC: F24J2/46
Filed: 1977-05-17
Abstract: In a solar heat collector system with an absorber of base metal, e.g. Fe or pref. Al, which is coupled to the consumer by a Cu pipe, serious damage can be caused to the absorber by electrochemical decomposition. This is caused by corrosion currents flowing between the collector casing of the absorber to the consumer and the copper pipes via. the earthed connection. This can be eliminated by breaking this circuit, pref. by insulating the absorber against the collector casing by embedding it in plastic foam.

Title: Air recirculation system for process ovens - having partial extraction of recirculating air with passage through fan and reheating of this stream to give reduced energy input
Inventor: KUTTERER WERNER
IPC: F27D7/00
Filed: 1977-11-16
Abstract: Recirculation system for process oven or dryers using hot air involves taking some of the recirculating air as primary air. This air is then compressed in a fan and heated. The air is expelled from an ejector type device to induce a secondary air stream inside the oven. The fan is suitably of a high pressure type and its outlet stream feeds directly into a heat exchanger. Used for enamelling stoves, drying stores and powder coating ovens, etc. The system reduces the electrical fan power by 50-75% and gives a better temp. distribution than a system involving total air passage through a fan.
