Abstract: Improved techniques are provided for forming a very thin polycrystalline layer of a semiconductor material on a glass substrate. The film material may be formed from a slurry of a semiconductor powder and a liquid carrier, and the slurry economically applied at room temperature by spraying techniques. Once dried, the film is compressed by the appli­cation of a substantial mechanical force. The compressed film is regrown in a heated atmosphere, forming a poly­crystalline film comprised of large mean diameter crystals, with many crystals having a mean diameter in excess of the film thickness. A high quality cadmium sulfide polycrystalline film suitable for forming a photovoltaic cells may be inexpensively manufactured according to these techniques.

Abstract: A logic processor-controlled data display apparatus having a display memory in which pixel data representing text for display is stored in bit-map form. The pixel data is produced for each display from character data stored in a background memory. When the character data is stored in bit-map form it can be read directly from the background memory bit-by-bit and written into the display memory as the pixel data. However, this process takes a large number of programme steps, so that the transfer of the data is relatively slow. The present invention provides for the storage in the background memory of character data in the form of machine code sub-routines. The sub-routine for a character contains instructions for identifying the shape-defining pixels (dots) of the character relative to a base dot position and the sub-routine is run to write these pixels into the display memory following location of the base dot position in the display memory. Figures 2 and 4 exemplify the invention.

Abstract: The method of this invention for determining the presence of atherosclerotic plaque antigen in serum comprises contacting the serum with anti-plaque antibody for a time sufficient to permit binding of the atherosclerotic plaque antigen with the anti-plaque antibody, and determining the atherosclerotic anti-idotype antibody, if any binding with the anti-plaque antibody. The anti-plaque antibody can be bound to an insoluble support, contacted with serum to permit atherosclerotic anti-idiotype antibody conjugation with the anti-plaque antibody, and the amount of resultant atherosclerotic anti-idiotype antibody bound to the insoluble support can be determined. 
     Alternatively, a precise amount of atherosclerotic anti-idiotype antibody can be bound to the insoluble support, and a mixture of a predetermined excess amount of labeled anti-plaque antibody and serum can be contacted therewith. The labeled anti-plaque antibody bound to the insoluble support or remaining in the mixture can be determined. Also, a precise amount of anti-plaque antibody can be bound to the insoluble support, and a mixture of a predetermined amount of labeled atherosclerotic anti-idiotype antibody and serum contacted therewith. The labeled atherosclerotic anti-idiotype antibody bound to the insoluble support or remaining in the solution can then be determined.

Abstract: An assembly to eliminate slack in a length of cord (20, 120) extending between axially spaced first (12, 112) and second (14, 114) cylindrical members. The cord (20) is wrapped in coiled lengths (22, 24, 122, 124) on the interior side walls (18, 19, 118, 119) of each member (12, 14, 112, 114). A control means (34, 134) acts between the members (12, 14, 112, 114) and coiled lengths (22, 24, 122, 124) to coil the cord (20, 120) onto one coiled lengths (22, 24, 122, 124) while uncoiling the cord (20, 120) from the other coiled length (24, 22, 124, 122). A guide means (36, 136) guides the cord (20, 120) onto and off of one of the coiled lengths (22, 24, 122, 124) while rolling means (38, 138) hold the coiled lengths (22, 24, 122, 124) in position to eliminate slack. The control means (34, 134) specifically includes at least two spokes, one (42, 142) to engage the U-shaped loop (32, 132) in the cord (20, 120) between the coiled lengths (22, 24, 122, 124) with the one or more spokes (40, 140) disposed within circular O-rings in rolling engagement with the respective coiled lengths (22, 24, 122, 124).

Abstract: A valve (42) in a medical ventilator (30) which controls the flow of gas from a pressurized gas source (32) to a patient for inhalation. Flow through the valve is choked and pressure upstream of the valve is held stable so that a known relationship exists between the position of the valve and the flow rate through the valve. An open loop control system (44,46) causes the valve to open or close as needed to deliver a preselected tidal volume of gas to the patient on each breath. Since the flow rate is known, no feedback to the controller regarding actual flow conditions is required. The exact positioning of the valve and length of time that the valve is to be held open is predetermined by the controller before the breath is delivered, and is repeated for subsequent breaths. Preferably, the valve is driven by a stepper motor (74) and the controller comprises a microcomputer. The controller compensates for ramping of the stepper motor as the valve opens and closes in determining the positions of the valve required to deliver the preselected tidal volume. To ensure precise engagement between a valve member (72) and a valve seat (62), the valve member is mounted on a flexible, linear wire (88). Additionally, a spirally wound spring (94) surrounds a stepper motor shaft (76) and biases the shaft so as to close the valve in the event of a power loss.

Title: Motor lubrication with no external case drain
Inventor: UPPAL SOHAN LAL
IPC: F04C2/10
Filed: 1988-02-16
Abstract: An improved lubrication system is provided for a motor of the type including a gerotor displacement mechanism (17), an inlet port (57), an outlet port (61), and valve means (19,55) operable to control the flow of fluid from the inlet port through volume chambers (29) of the dis­placement mechanisms and back to the outlet port, thus defining a main fluid flow path. A shuttle valve (85) communicates a flow of lubrication fluid from the main fluid flow path to a lubrication flow path (79,81,82,83) which flows through the bearings and spline connections of the motor. In accordance with the invention, a restrictor member 113 is located in the outlet port (61) and defines a restricted orifice 115 which restricts outlet flow from the motor causing a back pressure which generates the flow of lubrication fluid. After fluid flows through the lubri­cation flow path, it flows to the outlet port, downstream of the restricted orifice 115, recombining with the low-­pressure, exhaust flow from the motor. The lubrication system of the invention permits a greater flow of lubri­cation fluid, without loss of volumetric efficiency, and without the need for a separate case drain port.

Abstract: In the production of a multi-core flexible power line, in which an optical waveguide is arranged in one of the outer power core gaps instead of a partial protective conductor core, there is a risk that the high pressures and temperatures occurring during the extrusion and curing of the inner and outer jacket may damage the optical waveguides. Protection of the optical waveguides is achieved by a thermally insulating envelope (64), consisting of a plurality of layers of fabric strips and/or of fleeces, made of a material which is thermally resistant up to at least 200 DEG C, and having poor thermal conductivity, being arranged over the jacket (62) of the optical waveguide (6), and by the core gap holding the optical waveguide (6) being filled to more than 50% of the gap volume with fillers (52) of jute fibres or a similar material. This design is used especially in the case of line cables having an integrated optical waveguides, where the design protects the optical waveguides not only during production but also during use of the line cables for connection to mobile large apparatuses (excavators and dumpers) in the case of very high mechanical stresses. <IMAGE>

Abstract: In a searching for library documents that match the content of a given sequence of query words, a set of equivalent words are defined for each query word along with a corresponding word equivalence value assigned to each equivalent word. Target sequences of words in a library document which match the sequence of query words are located according to a set of matching criteria. The similarity value of each target sequence is evaluated as a function of the corresponding equivalence values of words included therein. Based upon the similarity values of its target sequences, a relevance factor is then obtained for each library document.
