Title: Rotary engine working on three stroke cycle - has elliptical rotor running in elliptical housing
IPC: F01C1/22
Filed: 1975-03-03
Abstract: The housing (1) of a rotary engine has an elliptical bore (4) with an elliptical rotor (2). The rotor (2) has an internal longitudinal rectangular slot which allows it to slide laterally on the shaft (3). Thus as the shaft (3) rotates, the rotor tips (23, 24) maintain contact with the housing bore (4). Air is drawn in through the port (9) and once the rotor tip (24) has passed the edge of the port, the air is compressed in the space (18) until the axis of the rotor is horizontal. Fuel is then injected through the orifice (8) and ignited by the plug (13). Continued rotation of the rotor (3) allows the gases to escape through the exhaust port (17).

Title: Appts. determining angle of inclination - limits effect of disturbing vibrations of non-protruding member
Inventor: SCHEDROVITSKY S S
IPC: G01C9/02
Filed: 1975-06-06
Abstract: The apparatus determines the angle of inclination especially in systems automatically controlling the position of the working components of coke levellers, land-improving installations such as drainage and soil conservation etc. Accuracy is increased by limiting the effect of disturbing vibrations of the non-protruding member. The angle is ascertained from the non-protruding member situated on the mounting axis. The inclination of the member is converted into an electrical signal. A vibration suppressor is provided for the non-protruding member. In the preferred embodiment this member is the the form of a ring (1) whose centre of gravity with respect to the mounting axis (3) is moved below the value of the square root of half the sum of the squares of the outer and inner radii of the ring.

Title: eutectic evaporator with ribbed inner pipe - has circular ribs on pipe for increasing cooling surface area
Inventor: FORMENTI FRANCO
IPC: F25D3/00
Filed: 1975-08-29
Abstract: The eutectic evaporator has a metal container for eutectic fluid. Into this container is place a meandering pipe which is immersed into the liquid and it has ribs for extending its heat transfer surface. When a thin layer of frozen solid eutectic liquid is deposited on the pipe then the heat transfer is carried out by means of the ribbed surfaces. Hence the time required for collection is reduced more than by half, even in the case of small temperature differences between the boiling and freezing temperature of the coolant. The metal rectangular container (1) houses a metallic tube (3) for accommodating the coolant. The gaseous coolant is blown through the pipe at the inlet (2) and it emerges at the outlet (5). The circular ribs (4) ensure good heat transfer.

Title: D:A converter controlled from computer digital memory - by periodic set pulses and delayed reset pulses with delay time proportional to weighting
IPC: H03M1/00
Filed: 1976-01-09
Abstract: The D/A converter is set periodically by a series of set pulses corresponding to the number weighting code and reset by reset pulses following the set pulses and with a delay time proportional to the weighting of the individual set pulses. A number of D/A converters with different addresses can be controlled by a composite code time multiplexed to the converters and containing the set pulses. The converter contains a binary memory and the set-pulse gating circuit is connected to the memory. The advantage lies in using a memory of drum or disc form of a digital computer to control the converter directly.

Title: Lightweight heat-exchanger suitable for aircraft - with some aluminium parts replaced by high temp. metal to reduce stress due to high temps. and pressures
IPC: F28D9/00
Filed: 1976-02-05
Abstract: Lightweight heat exchanger of aluminium or (alloy) for high temp. fluids, has a feed header of titanium or other high temp. metal. The main shell of the exchanger is joined to the feed header by solders or welds which are protected from heat damage by a partition which forms a separate chamber to retain the fluid under conditions of reduced circulation. The partition (or baffle) is made of the same metal as the header and is fixed to the wall. The exchanger is esp. suitable for use in aircraft or space craft where the high speeds result in the cooling fluid, i.e. the external air, being itself at a high temp. Replacement of the aluminium by a high temp. metal in the feed header gives some protection from heat damage which may otherwise occur. Other vulnerable areas, which are the welds, are protected by a partition in the inlet header which retards circulation, thus reducing strain on the welds from press., and a baffle placed between the partition and the exterior wall of the header which reduces the heat transmitted by conduction. The cooling air passes between the tubes, carrying the fluid to be cooled, which have fins to increase the surface area and hence the efficiency.

IPC: B65G17/12
Filed: 1976-04-09
Abstract: The chain conveyor has a drive chain, which is composed of elongated round steel links (25) which are arranged in parallel planes. These links (25) are connected by means of transverse bolts (23, 28). In order to produce a chain conveyor, in which the simple and rigid attachment of conveying elements (13) to the drive chain is possible while dimensions are kept small, the conveying elements (13) have channel-like recesses on their rear sides. Two flanges (18) with bores which are aligned with one another are releasably attached to the mutually opposite side walls (17) of the recesses, in order to accommodate the pins of one of the transverse bolts (23) of a pair of transverse bolts which are used to attach a conveying element. The pins of the other transverse bolt (28) of this pair of transverse bolts are guided in two pairs by longitudinal guides, which are bounded by sliding strips (19).

Title: Inspecting cracks e.g. in metals - with subsequently emulsifiable dye penetrant compsn. using two different biologically degradable nonionic surfactants
IPC: G01N21/91
Filed: 1976-08-09
Abstract: Process comprises applying a biologically degradable liq. dye penetrant compsn. on surface. Compsn. consists of: (1) a biologically degradable nonionic oxyalkylated alcohol or mixt. as 1st surfactant, and (2) a small quantity of dye, soluble in 1st surfactant. The 1st surfactant has limited solubility in water and prevents washing away of dye penetrant with water. The covered surface is contacted with an emulsifier contg. a biologically degradable oxyalkylated alcohol or mixt. as 2nd surfactant which is water-soluble and allows washing out of emulsified penetrant compsn. with water. Emulsified penetrant on object surface is then contacted with water. Dye penetrant is removed from surface, without removing dye penetrant from cracks. Surface of object is then studied under illumination to observe coloured traces of dye in cracks. Emulsified dye penetrant can be removed easily, using small vols. of water at standard wash press. Defects show up brightly. Compsns. neither corrode nor damage metals, e.g. steel, Al, Ti and are odourless.

Title: Drive chain scraper attachment - has U=shaped member welded to link and bolted to angle section to relieve link of torsion loads
IPC: B65G19/24
Filed: 1976-11-25
Abstract: In order to transmit a force from the link (S) of the driving chain (C) to the angle iron (CR) a V-shaped member (P) is welded to the link (S). The V-shaped member (P) has a central rib with a hole for a bolt (FX). The vertical leg (E1) of the angle (CR) has a corresponding hole so that the V-shaped member can be bolted to it. The operating load is transmitted by pressure of the V-shaped member on the inner face (I1) of the vertical leg (E1) of the angle iron (CR). This means that the bolt (FX) is not subjected to any fatigue loading during operation of the drive.

Title: Internal sound sensitivity treatment system - with sound energy frequency modulated as inverse function of control modulation
IPC: H04R25/00
Filed: 1977-01-17
Abstract: The system treats troubles connected to internal sound sensitivity in speech therapy, by delivering modulated sound energy into the ear. The energy is frequency modulated as an inverse function of a control modulation. This is done starting from a frequency near but below the highest audible one corresponding to a zero value of the control modulation factor. The power of the sound energy delivered into the ear can be constant, and near to but below the pain threshold. The equipment used can have an oscillation generator whose frequency is controlled electrically as an inverse function of a modulation factor, as supplied by a tape recorder output.
