Title: Trochoidal rotary piston IC engine - with pre-combustion chamber for higher efficiency; several power impulses per rotation
IPC: F02B55/14
Filed: 1975-02-25
Abstract: The unit, of generally conventional shape and construction, has only exhaust openings (one min.) (131, 132) in the casing (1) periphery. Air inlet openings (one min.) (135, 136) in the casing sidewalls communicate with precombustion chambers (11c-11e) in the piston (133) shaped so that with the piston rotating the gas flow from them into the main combustion chamber augments engine power. Fuel injection is also through a sidewall, pref into the incoming airflow (opposite (13, 134)plugs are fitted (not shown). Eelectronic controls initiate combustion as appropriate, e.g. twice per rotation as shown, to peak when the rotor is respectively in the cross-hatched (133) and the chain-dotted (137) positions.

Title: Vehicle range determination and display device - measures amount of fuel remaining and compares with voltage representing average consumption
Inventor: SCHULTE BURKHARD
IPC: G01F9/00

Title: Combiner-demodulator for PSK suppressed carrier signals - includes filters for recovering phase-coherent carriers after multiplying
Inventor: BILSENS GUNARS
IPC: H04L1/06
Filed: 1976-06-11
Abstract: Two signals received by spaced antennae and having identical data signals, phase modulated on frequency-identical suppressed carrier signals, are combined to produce an error-free data output. Each input signal, after heterodyning, is multiplied by a distinct feedback signal to produce a phase-coherent carrier and a recovered data signal. Each carrier is filtered by a narrow bandpass filter and connected to a separate adder. The two multiplier outputs are also added together, then filtered in a low pass filter to provide a combined recovered data signal. This combined data signal is added separately to each coherent-phase carrier to provide the two distinct feedback signals for the input multipliers.

Title: Bulk material discharge system - using mass flowmeter for automatic control of discharge gate valve; e.g. for charging coking ovens
Inventor: FEDERHEN BERND ING GRAD
IPC: C10J3/30
Filed: 1977-03-15
Abstract: A device to discharge bulk material from a bunker includes a mass flow meter which senses the actual value of the flow rate continuously and feeds them to a controller. This contains the stored desired values for the flow rate and produces an output signal in direct proportion to the instantaneous discrepancy between actual and desired value. This output signal actuates the drive of a gate valve for the control of the flow rate accordingly. This controls the flow rate of bulk material continuously and smoothly independent of the pressure of a container to be charged. It has a flat response and can adapt itself to varying conditions, e.g. for charging coal gasification reactors at pressures of 30 bar.

Title: Punch for locating holes in colour print negatives - has mounting on illuminated glass topped table for alignment of diagonally opposite holes in negatives and film
Inventor: JAHN HELMUT
IPC: G03F9/00
Filed: 1977-04-02
Abstract: The colour printing of pictures or illustrations is carried out by using a set of negatives with each negative being of a different colour. To produce a good printed picture each negative must be accurately aligned with the carrier film. This can be achieved by using a table with a glass top (3) which is illuminated by lamps fixed below the surface. The negatives and carrier film are aligned by hand and then placed under the punch (4) which is actuated by a lever. Two diagonally opposite holes are punched through the negatives and carrier film. Pins are then pladed on these holes to keep them correctly aligned during printing.

Title: Heart pacemaker with rechargeable battery - has transformer type recharging system and frequency sensor monitoring battery condition
Inventor: HOLZER WALTER
IPC: A61N1/378
Filed: 1977-05-06
Abstract: Heart pacemaker is used for implantation in the human body, and has an electronic spacer arrangement. Electrodes are provided for the excitation of heart muscles and batteries are used as power sources. The batteries are recharged externally without an operation which could involve risk. The battery of the pacemaker is recharged by means of an induction coil with rectifier. This arrangement is charged externally outside the body by a second solenoid and the two solenoids are linked in the form of a transformer for transferring the required recharging energy. The heart pacemaker has a generator circuit whose frequency is modified in relation to the battery voltage and this frequency can be measured externally by inductive or capacitive methods. A monitoring receiver is arranged outside the body which triggers an alarm signal when a frequency is transmitted which corresponds to a critical battery voltage.
