Title: Rotating and reciprocating piston electric motor or generator
Inventor: WYRSCH ISO
IPC: F02B75/28
Filed: 1989-12-19
Abstract: The rotating and alternating piston machine is an alternating or free piston machine in which the pistons effect a rotating and alternating movement. Main characteristics: 1) the use of rotation or alternation/rotation, for example in order to control the ports provided in the cylinder walls of two- and four-stroke engines, pumps and compressors; 2) simple conversion of rotating and alternating movement by mechanical or electrical means. The rotating and alternating piston machine offers the possibility of: pumps, including the electric drive, in which there is only one rotating part; direct conversion of the alternating movement of the piston into electrical energy; control of the gas movement by the piston; operation of other ports having specific functions (for example, introducing additional compressed gas, discharge ports operating in succession etc.); free selection of the number of piston strokes per rotation; choice of piston stroke kinematics; powerful rotation or swirling of charge; easily designed compact and inexpensive machines; possible integration of a compressor without having to provide for an additional volume and virtually without any weight increase. In the two-stroke combustion engine, in which the gas exchange is controlled by the pistons (2 and 5), the useful power is available at the central shaft (14), which carries the rotating and alternating piston (2) in a longitudinally-slidable but rotationally-fixed manner. Movement is converted by the oscillating shaft (35) and transmission element (38). The engine is provided with four working chambers and has a 100% mass balance.

Title: Carbonaceous fibres having coil-like filaments and method of producing same
Inventor: KAWAGUCHI MASAYUKI
IPC: D01F11/12
Filed: 1990-06-27
Abstract: A carbon fiber, which is novel in comprising coil-like carbon filaments, is obtained by vapor phase pyrolysis of an aliphatic hydrocarbon, preferably acetylene, at 300-1000 DEG C in the presence of a transition metal catalyst such as Fe, Co, Ni or Cr. The hydrocarbon gas may be mixed with hydrogen gas and/or a diluent gas. Each of the coil-like filaments is 0.05- 5 mu m in diameter and is coiled such that the coil outer diameter is 2 to 10 times the filament diameter and that the number of turns per length of 10 mu m is from 5/D to 50/D, where D is the coil outer diameter in  mu m. The carbon fiber may comprise linear filaments too. Carbon of each filament of the novel fiber, at least in a surface layer of the filament, can be converted into a carbide of a Group IV element such as Ti, Si, Zr or Hf with no change in the coil-like shape of the filament by reacting a gaseous compound of the Group IV element with the carbon fiber at 1000-1500 DEG C in a reducing gas atmosphere, preferably in hydrogen gas. <IMAGE>

Title: Computer with ram-based video integrated circuit
Inventor: BAILEY ROBERT
IPC: G06F3/153
Filed: 1990-07-31
Abstract: A computer which provides a video signal for display has a central processing unit (CPU) 13 which executes a program to provide video data for a display 27 which is organized as a matrix of pixel elements, each pixel element being represented by a certain number of bits of video data stored within a random-access memory (RAM) 43 in the computer. A video integrated circuit 14 is coupled to the RAM 43 to provide N bits of video data per pixel to the display at a dot clock rate consistent with the requirements of the display. This video circuit 14, rather than having its own video RAM, shares the system memory (i.e., RAM) with the CPU. A memory controller 12 arbitrates access to the RAM between the CPU and the video circuit in a manner that denies access to the RAM by the CPU whenever the video circuit is reading video data from the RAM. All of the video circuitry is incorporated on a single printed circuit board with the rest of the computer circuitry, thereby obviating the need for a separate video card with its own expensive video RAM, and permitting access to the video data at a substantially faster rate than that of past systems. <IMAGE>

Title: Bandgap infra red radiation detector
Inventor: EDEN DAYTON D
IPC: G01T1/24
Filed: 1991-09-09
Abstract: A radiation detector device for radiation of the infrared region and regions of shorter wavelengths comprises a dipole antenna 36 mounted on a substrate 12 and connected through blocking contacts to a bandgap detector element 40. The dipole antenna has a length which is approximately one half the wavelength of the incident infrared radiation. The bandgap detector element has linear dimensions which are each substantially smaller than the wavelength of the detected radiation. A group of detector devices are combined to form an array which can produce a pixel signal for an image. Unlike conventional infrared radiation detectors, the disclosed detector device is capable of producing a usable output signal without the need for cooling below ambient temperature. A further infrared radiation detector device has an array of detectors each of which comprises a pattern of parallel detector elements. Each detector produces a pixel signal for an image. The elements of the detector are photoconductive or photovoltaic bandgap materials, and the elements are spaced apart at a dimension which is equal to or less than the wavelength of the radiation to be received. Additional layered structures above and/or below the detector elements provide impedance matching between free space radiation and the radiation impedance of the detector elements, to increase the capture of radiation.

Title: Moulding a double-walled product
Inventor: HOLGATE JOHN SYDNEY
IPC: E01F9/011
Filed: 1993-04-20
Abstract: A method of moulding a double-walled socket is achieved by forming a mould cavity 22 by inserting a male mould element into a female mould element. The mould is charged by introducing particulate material (thermoplastic powder) through filler pipes 28 into cavity 22 and then rotated whilst being heated to distribute the material along internal surfaces of cavity 22 so that the moulded product forms in the cavity 22. The mould is cooled and the male element removed from the female element to release the moulded socket. The shrinkage distortion and surface unevenness of the socket bore is reduced in such a double walled socket. A spigot having axially spaced annular walls which mate with corresponding walls in the socket provides an assembly which is easily releasable. The mould may also be rocked about an axis as it is rotated. A bollard 2 and a socket 1 to be used in combination may be so produced. <IMAGE>
