Patent DE-3001052-A1 (DE)
Title: Three motor cine projector reversible drive - has thyristor switching to gate motor and lamp to protect film and preserve loops at reverse
Inventor: ACKERMANN MANFRED
IPC: G03B1/54
Filed: 1980-01-12
Abstract: The control circuitry is for a reversible drive cine projector. Signals from the spool motors are relayed to the film gate drive motor and the projector lamp so that their operation is co-ordinated, and the film loops preserved plus lamp switched off, to prevent film damage mechanically or by heat. A thyristor (BRX 44) is used when the spool motors are stationary to control the current to the film gate motor (109) via a transistor (107). The transistor (107) acts as a switch for the gate motor (109) and is controlled by a base connection to a preceding transistor (105) from the thyristor (BRX 44). The thyristor (BRX 44) is also used to control the projection lamp (103) so that when the projector main switch is set to a project position, the thyristor is open circuit to the reference rail (7) and, when correct conditions occur on the AND gate (118), current flows through a diode (104) and relay (101) so that the lamp (103) contact is made (102). No separate control knob is required to switch the lamp on; it is done automatically when the projector is running.

Title: Closet cistern nozzle flushing equipment - has differential piston with larger working face towards water tank
Inventor: LECHNER VIKTOR
IPC: E03D3/00
Filed: 1980-01-18
Abstract: The equipment flushes a cistern nozzle by means of water from a storage tank in which it is held under pressure, the tank being connected between the nozzle and a mains filling valve with different piston. The working face of the larger part (9) of the piston (8) in the filling valve is towards the interior of the tank (1), while that of the smaller part (7) forms a seat for the filling valve. The latter controls water inflow from the mains into the tank via a passage (10) dependant on mains pressure and the ratio between the workig face areas of the piston. An air-filled rubber bellows (2) is mounted in the tank.

Title: Automatic developing system for photographic paper - has stepped distribution valve connecting compressed air to various processing liq. containers to force selected liq. into bath
Inventor: BERNHARDT RAINER DIPL ING
IPC: G03D13/04
Filed: 1980-06-26
Abstract: Several containers are provided for different processing liquids. Each container is connected to a gas line (57) conveying gas under pressure to the container. The gas drives the liq. up through an outlet line (56) into a collection line. A distribution valve (70) determines which liq. passes to the collection line. This valve is located in the has lines and not in the liq. lines leading from the containers to the developer vessel. A sensor detects the flow of liq. and actuates a timer that moves the distribution valve on after a given time has elapsed. The distribution valve's input is connected to the source of compressed gas, e.g. an air pump, and its outputs are connected to the gas lines leading to the containers. The sensor is located in the collection line. The distribution valve is driven by a stepping motor (72). A two-way valve is located between the distribution valve and the pressure source and connects the valve either to that pressure source or a suction source. Suction is applied to the gas lines at the end of each step. The suction pump is the opposite end of the pressure pump.

Title: Stratified charge gear motor with antechambers and afterburners as a turbine rotor
Inventor: BREUHAMMER HORST
IPC: F02B53/02
Filed: 1981-01-20
Abstract: The gear motors for internal combustion engines, for which universal applicability is claimed in the patent, operate as turbine rotors without oscillating machine parts in a housing and utilise fuels of all kinds better than all internal combustion engines hitherto by virtue of a longer and completely different utilisation of the internal combustion expansion gas over about 270 DEG  of the 360 DEG of the arc of revolution. The problems of existing engines, e.g. reciprocating piston engines, are the expansion gas pressures required for a 4-stroke process of 2 x 360 DEG  = 720 DEG  for the mechanical power stroke, which extends over only 120 DEG . These pressures had to be sufficiently large to ensure that the remaining 600 DEG  of circular arc and the instantaneously required torques were overcome with kinetic energy from the previous working cycle because the physically poor leverage, which varies widely in length during a stroke, is, after 120 DEG , at the bottom dead centre and end of the energy utilisation and the necessarily excessive energy residue is then released without being used before the next cycle. The same applies to turbine power plant types of construction due to excessively high throughputs and flow rates owing to poor frictional engagement. The solution in my engine inventions is as follows: a lightweight construction because high compressions are avoided, the ignition temperatures being those for diesel and heavy-oil combustion - with stratified charge as a rotary piston engine in combination with meshing engagement, used as turbine rotors. <IMAGE>

Title: Device for irradiating a reclining subject
Inventor: KRATZ WALTER
IPC: A61N5/06
Filed: 1981-03-28
Abstract: An irradiation device for irradiating a reclining subject with an irradiation hood from which preferably UV radiation emerges at the bottom. The irradiation hood is fitted to a carrying arm which can be pivoted about a horizontal axis. Thus, the irradiation hood can be moved between a raised resting position and a lowered irradiation position, and at the same time it can be rotated relative to the carrying arm. In order to ensure that the irradiation hood exposes an especially wide entrance in its raised resting position and at the same time permits particularly uniform alignment of the emitted radiation in its lowered operating position, there is a control arm which controls the irradiation hood in a four-bar mechanism, so that the irradiation hood is held virtually horizontally within the tolerances specified for the operating position and is guided into an approximately vertical position when the carrying arms are pivoted upwards.

In this clutch brake, the internal circumferential edge of the clutch plate enters into rotary connection with the pressure plate, the circumferential edge of the clutch plate comes into sliding engagement in the direction of the output shaft of the revolving element, and the clutch plate is separated from the fixed element when due to the actuation of the control rod the pressure plate is pressed against the pressure spring and is subsequently pressed against the disc. This arrangement can furthermore have a viewing window, a water draining opening, a dust cover or the like for the purposes described here. <IMAGE>

Title: Filter press
Inventor: STAHL WERNER PROF DR
IPC: B01D25/12
Filed: 1981-07-21
Abstract: A filter press having a fixed or movable filter cloth and a multiplicity of filter plates which are arranged tightly next to each other during the filter phase and are moved apart for filter cake discharge. By means of a control device, in each case a compressed air source is connected to a presettable fraction of the cavities between the filter plates in order to reduce with the aid of the compressed air the residual moisture of the filter cake after the filter phase, by preferably blowing air through the filter cake only until the pores and the pore channels in the filter cake are freed from the mother liquid with the aid of the compressed air. To save compressed air, the air transmission is monitored and shut off, as soon as a sudden increase in air flow is indicated, so that a transition from piston flow to free passage flow is achieved.
