Title: Sliding-vane rotary compressor
Inventor: SAKAMAKI HIROSHI
IPC: F04C18/348
Filed: 1984-05-18
Abstract: To reduce friction between the vanes 16 and the rotor 10 the walls of the vane grooves 15 are coated with a metal oxide 1. The oxide may be formed by anodic treatment of the groove walls. Preferably, the rotor is made of aluminium and the vanes are made of carbon. The entire rotor may be anodically oxidized and, saving the groove walls, thereafter covered with a layer of resin e.g. a polyimide, polyester, phenol, or polytetrafluoroethylene resin, Fig. 4, so as to reduce friction between the rotor and the casing. The radically outer edges of the vanes may engage with a rotary casing- liner, or "sleeve", 30 supported by an air bearing 40, to further reduce friction. <IMAGE>

Patent GB-2157314-A (GB)
Title: Home brewing system
Inventor: CROSS JOHN VALENTINE
IPC: C12C13/10
Filed: 1985-04-09
Abstract: The system for the home brewing of beer or wine consists of preparing a yeast fermentable substrate syrup such as a high maltose syrup with a specified sugar spectrum. To this may be added protein, amino acids, and yeast nutrients. The ingredient-balanced syrup is sterilized and aseptically packaged. The user empties the sugar solution into a container and adds potable water at fermentation temperature to dilute the substrate. Yeast is added and the container is sealed and placed under a water seal. The container is preferably collapsable. After fermentation, the water seal is removed and the container is closed or sealed and can be used to dispense the beverage once settling has taken place, the collapsability of the container preventing or eliminating the necessity of air entry to replace the liquid withdrawn. This process eliminates the usual boiling of the wort and subsequent cooling period to reach fermentation temperature.

Patent GB-852044-A (GB)
Abstract: 852,044. Embroidery. DOUGHTY, J. C. Sept. 17, 1958 [Sept. 17, 1957], No. 29234/57. Class 112 [Also in Group VIII] Selected groups of wales and/or courses are constricted or distorted at predetermined spaced points or localities, to produce on the face of the fabric undulatory cable-like conformations or puckered effects, the constrictions or distortions being produced during knitting (Group VIII), or subsequently to knitting, by incorporating binding threads by hand (e.g. with the aid of a sewing needle, crochet needle, or latch needle) or by employment of a sewing machine. The positions at which binding threads are to be introduced subsequently, may be indicated during knitting by, for example, variations in colour, stitch formation, or stitch size. To produce wale-wise effects a single vertical of ribbing may be constricted or distorted at spaced points there along, or verticals b, c of ribbing may be constricted at staggered points d. The ground fabric may be plain as at a. Alternatively, the ground fabric may be produced on two needle beds from three contrastingly coloured yarns of which only a first one appears on the face of the fabric whereas the two or three verticals of rib fabric which are to form the cabled effect are each knitted from a different one only of the three yarns, the other two being floated in each case. Horizontal striping may be employed. The undulatory formation may form an edging for a garment (e.g. an open-fronted cardigan) and a walewise extending trough w of single bed knitting may be provided between the edging y and the rib fabric x of the garment, to provide a strip for buttons or button holes. By simple purling of courses of knitting, it may be arranged that the undulatory effects in the garment shall be horizontal or inclined.

Title: Memory refresh and parity checking circuit
Inventor: RAMSAY JOHN ROBERT
IPC: G11C7/10
Filed: 1986-01-29
Abstract: A circuit for use in conjunction with a microprocessor for refreshing, checking and correcting data signals stored in a dynamic memory. The circuit utilizes a direct memory access controller for transferring data signals stored in successive locations of the dynamic memory to a non-existent peripheral. Data signals appearing on a data bus as a result of the data transfer, are applied to a parity checking circuit for generating an interrupt signal to the microprocessor in response to detection of parity errors in the data signal. The microprocessor then performs a data recovery routine in which correct versions of the data signal stored in a non-volatile memory, are transferred for storage in the dynamic memory under control of a microprocessor. Parity errors in data signals stored in the dynamic memory are thus corrected prior to being accessed by the microprocessor.

Title: Sorting ore particles
Inventor: NORDIN LEE
IPC: B07C5/342
Filed: 1987-04-02
Abstract: Ore particles (14) are sorted by subjecting them to electromagnetic radiation in the microwave part of the spectrum, e.g. by passing through chamber (18), the frequency of the radiation being at the resonant frequency of water or that of one or more target minerals or possibly a combination of such frequencies. The resultant heat emission characteristics of the particles are deflected by e.g. infrared detector (20) and analysed at (24). Particles exhibiting a desired heat emission characteristic are separated at (26) from other particles which do not exhibit such characteristic. In one application of the method, kimberlite particles can be separated from non-kimberlitic particles, typically gabbro. This is achieved by subjecting the particles to electromagnetic radiation at a frequency of about 2450MHz, this being a resonant frequency for water, it being known that kimberlite has a higher water content than gabbro. Line scan camera 22 provides signals indicative of the size of the particles which are fed to processor (24). <IMAGE>
