Title: IC engine with constant compression throughout working range - has exhaust gases cooled and fed back to air fuel mixture intake
Inventor: LOPIC FRANC
IPC: F02M26/61
Filed: 1975-10-14
Abstract: The exhaust gases are collected after leaving the silencer or expansion chamber (2) and fed via a flexible plastic tube (7) back to the air fuel mixt ure intake (3) downstream to the main throttle valve (11). The exhaust to atmosphere has a spring loaded pressure relief valve (10). The exhaust feed back pipe is fitted with a throttle valve (12) which is mechanically coupled to the main fuel mixture valve (11). The coupling between the two valves is adjustable and so arranged that on slow running, the remaining cylinder volume is filled with the non combustible exhaust gas which is cooled before entering the cylinders.

Title: Light-weight double piston IC engine - works on two stroke compression ignition principal for outboard engine
Inventor: HITZ MICHAEL
IPC: F02B75/28
Filed: 1975-10-17
Abstract: The engine has a common cylinder for the counter working double piston. The pistons are joined to upper connecting rods working two armed levers pivoting on a fixed axis. The two armed levers ar coupled to lower connecting rods joined to the crankshaft. One side of the crank shaft has a cam to actuate the fuel pressure pump. Fuel is injected directly into the combustion chamber. The one piston opens and closes the exhaust ports and the second piston regulates the inlet ports. Scavenging and combustion air is forced into the cylinder by a rotating compressor turned by the crank shaft on the fly wheel side. The hydraulic pumps are fixed to the two armed lever axis and have outlet pressure relief values.

Title: Controlled projection system for wiring assembly - uses optical projection of assembly sequence steps with numerically controlled beam
IPC: H05K13/06
Filed: 1975-10-24
Abstract: A numerically controlled projection display system enables the location of components and wiring paths to be established during assembly processes. A light source (20) is directed over a lens system (21, 22) and a projection display control unit (23). The controlled beam is then focussed (24) and directed onto the component assembly process (25). Typically, a small process computer may be pre-programmed to generate the necessary sequence of events required. The process is claimed to the more efficient for low quantity assembly processes and superior to systems relying on a projected photographic image.

Title: Digital controller for furnace heating system - reduces heater power before desired temp. is reached to avoid overshoot
Inventor: ARNOLD WERNER
IPC: G05B11/28
Filed: 1976-12-24
Abstract: The digital controller regulates the heating power of a heating installation, esp. a furnace. It is designed to reduce the supply of heating power before the desired lamp is reached so as to avoid a temp. overswing. The desired temp. is held in a store and transferred to a counter each time an on pulse occurs. The switch-on pulse train and a monitor pulse train have equal frequency but are 180 deg. out of phase. A measurement pulse signal is fed to the counter with frequency dependent on a measurement value but higher than the switching frequency. The measurement pulses are checked against the desired value between switching pulses to determine the heater duty cycle or switch-off.

Title: Self cleaning dust filter - having hinged dampers interconnected by rope or chain to select cleaning mode
Inventor: MARGRAF ADOLF DIPL ING
IPC: B01D46/24
Filed: 1977-01-31
Abstract: Dust filter consists of a housing with a partition wall contg. slots from which the filter elements are mounted. The clean air side of the filter elements has two outlets each sealed by a hinged damper. One leads into the clean air outlet duct while the other connects with the purge gas header. The two dampers are connected by a rope or chain which runs over an actuator device. By this means as one is opened the other is closed. Both ensure good sealing. The rope is longer than required to ensure complete sealing of each flap. In a varn. the flaps can have two sections hinged in the centre with one side closing upwards and the other downwards. Used to collect dust from gas streams. Changing from clean air duct to the back flush duct is facilitated.

Title: Artificial vortex to remove gas bubbles from a flowing liq. - which is formed behind a curved plate as the main flow turns aside
Inventor: BUDDENHAGEN UWE DIPL ING
IPC: B01D19/00
Filed: 1977-02-02
Abstract: Gas bubbles are to be removed from a flowing liq. by means of a vortex on which the bubbles will be transported to an area of quieter flow. The axis of the vortex is perpendicular to the direction of the main liq. flow (e.g. horizontal and at right angles above a horizontal flow), and the vortex is pref. formed at a point where the main flow turns: the sense of rotation of the vortex accords with the direction of the main flow.

Title: Watertight dynamic microphone capsule - uses sealed housing for coil topped by three membrane diaphragm system
Inventor: ROHDE FIRMIN DIPL ING
IPC: H04R1/44
Filed: 1977-03-03
Abstract: The watertight microphne capsule is for use in radio or intercom equipment used on liferafts etc. where the equipment is likely to be completely submersed in fresh or salt water. Precautions have also been taken to prevent water pressure, due to ingress, affecting the operating characteristics of the capsules. The magnet system (3) and the coil of the dynamic insert are covered by an inner membrane (4) and form a sealed housing. The inner membrane is connected by a post (6) through an intermediate supporting membrane (7) to an outer membrane (9) which is under a cover through which bore holes (11) allow sound waves to enter. An 'O' ring (22) seal prevents water entering the lower section of the capsule but breather holes (12) permit equalisation of pressure between the outer and intermediate membranes to cater for any water ingress and enable continued satisfactory operation of the capsule.
