Title: Remote control sender for T.V. receivers - generates pulses of the same carrier frequency but different width for different switching functions
Inventor: MINNER WILLY
IPC: H03J1/22
Filed: 1973-09-27
Abstract: The pulse width is an integral multiple of a basic time interval. A voltage divider consists of nonlinear components operated in a forward direction. Fixed voltage generated at this divider has an amplitude which corresponds to the selected switching function. It is compared with a rising voltage, so that the ultrasonic sender is switched on at the start of the rising voltage, and switched off on reaching the fixed volage. The voltage divider consists of a chain of diodes through which a current flows only when a switching function key is operated. It initiates the sender further functions. Alternatively the above diode chain may consist of Zener diodes or other components with nonlinear current/voltage characteristic.

Title: HV layer winding for star-coupled single-phase transformers - uses paper insulation without unacceptably increasing cores limb spacing
Inventor: BROSZAT GOTTFRIED
IPC: H01F27/32
Filed: 1973-11-07
Abstract: The HV layer winding, for star-coupled single-phase transformers, has the potential of the first h.v. sub-winding on one limb of the transformer core decreasing as the distance between winding layers on this limb increases. The outermost winding layer of the first sub-winding is connected to the second outermost layer of the second sub-winding. The second sub-winding is insulated against earth and against itself for voltages roughly equal to half the operating voltage, whilst the first sub-winding is insulated for the full voltage. This arrangement allows paper insulation to be used without fear of tearing and without increasing the distance between limbs by unacceptable amounts.

Device is simple in construction, and easy to inspect and maintain.
Patent DE-2406340-A1 (DE)
Title: Thermoelectric plate edge heat treatment - by bar radiators disposed alongside plate conveyor line
Inventor: GUSTKE WOLFGANG DIPL ING
IPC: E06B3/673
Filed: 1974-02-11
Abstract: The edges of the thermo-electric plastics impregnated plates are heat treated during their journey on a roller conveyor by thermal radiation from electric rod elements disposed in slot aperture heat insulation casings into which the plate edges project when correctly set. The casings are attached to blocks which can slide on bars extending at right angles across and above the plates. These blocks may be simultaneously displaced by equal distances in opposite directions by means of a lead screw with two counter directional pitch threads. The system permits the rapid curing of the plastic impregnation within minutes rather than days.

Title: Pressure operated switch with diaphragm actuation - has diaphragm connected to switching element moved according to pressure pulses
Inventor: CSUTOR ENDRE
IPC: H01H3/24
Filed: 1974-03-18
Abstract: The pressure operated switch is actuated by pressure medium pulses transmitted by an external diaphragm-like pressure element. The latter is connected to a switching element, carrying out the mechanical switching motion and transmitting the pressure pulses into switching motion. The mechanical switching element is subjected to a spring stress and is provided directly on a second, inner diaphragm of the switch. Preferably the switching element forms a one piece with the inner diaphragm, which may form a folding structure and a part of a pot-shaped disc with a wide edge, forming with the first diaphragm a pressure-type chamber. This pressure chamber may be filled with a gaseous or liquid pressure medium.

Title: Retractable cosmetic tweezers in neat plastics case - have resilient arms actuated by leaf springs moving relative to each other
Inventor: SCHMIDT EDMUND
IPC: A45D44/00

Title: Forming die - uses relatively resilient stock die to absorb impact when forming nuts or bolts
Inventor: AKAMATSU MOTOTSUGU
IPC: B21K1/64
Filed: 1974-07-30
Abstract: Forming die with an upwardly open die cavity comprises an upper die member of hard material with a portion of the total die cavity extending through, and a lower die member having the lower portion of the die cavity.

Title: Bean meal manufacture - from broken beans by separating low and high grade parts and removing former pneumatically
Inventor: PALYI LESLIE
IPC: A23L13/40
Filed: 1975-03-18
Abstract: Broken beans are turned into beam meal for human consumption by separating in a dry milling process the low-grade parts from the high-grade parts. After pneumatic separation most of the low-grade particles are passed to a cracker where remaining shell parts are removed. The light products are finally separated from the solid products in a pneumatic separator. This recovers 65-70% of the broken beans for human consumption; the meal produced from them fetches five-times the market price of the present broken beams which are used as animal feeding stuff.
