Title: Separation of the constituents of CO2 hop extracts
Inventor: TODD PAUL H
IPC: C12C3/10
Filed: 1986-03-11
Abstract: A process for the separation of the constituents of CO2 hop extracts employing aqueous alkali, and also a process for the conversion of the separated or unseparated alpha-acid fraction into an iso-alpha or isohumulone fraction by a process which requires heat alone are disclosed. The two steps can be combined into a single two-step process. The critical feature is the concentration of the alkali which is used in an up to equimolar equivalent with respect to the alpha-acid present, so that the pH falls during isomerisation thus minimising the formation of humulinic acid. The ultimate iso-alpha-acid or isohumulone can be used in the bittering of beer, without any of the usual synthetic contaminants or other unnatural conditions. The non-acidic fraction may be employed in the flavouring of beer in the usual manner, whereas the beta-acid fraction may be converted to hydrogenated iso-alpha acids or isohumulones, also for employment in the bittering of beer.

Title: Roller structure
Inventor: TAKAHASHI SHIGEO
IPC: G11B15/60
Filed: 1987-09-29
Abstract: A miniature roller structure e.g. for guiding a tape in a video or tape recorder, comprises a shaft (15), a small roller (10) including an elastic rubber cylinder (11) and a sleeve (12), and a plurality of bearing balls (30). The sleeve (12) is integral with the inner periphery of the elastic rubber cylinder (11), and is mainly composed of polytetrafluoroethylene (fluoroplastics). The shaft (15) is fitted in the roller (10). The bearing balls (30) are fitted in a circumferential or annular groove (16) formed in the shaft (15). The bearing balls (30) are in rolling contact with the inner periphery of the roller sleeve (12) and the base of the groove (16) in the outer periphery of the shaft (15). The groove (16) is at a middle point between the opposite ends of the roller (10). The depth of the groove (16) is such that the bearing balls (30) protrude slightly from the groove, so that a slight gap is formed between the inner periphery of the roller (10) and the outer periphery of the shaft (15). The axes of the roller and shaft are thus slightly tiltable in relation to each other. In an alternative embodiment the groove 16 is formed in the inner periphery of the roller sleeve 12. <IMAGE>

Title: Global serial channel for microcontroller
Inventor: HAYEK GEORGE
IPC: H04L29/02
Filed: 1988-01-11
Abstract: The present invention is directed to an onboard multiprotocol communications controller global serial channel ("GSC"). The GSC as disclosed and claimed herein is for use with an 8-bit microcontroller for intelligent communications with peripheral systems or components. The microcontroller and GSC are implemented on a single integrated circuit chip. The microcontroller is a derivative of the 8051 series of microcontrollers sold by INTEL Corporation. The invented GSC interface supports synchronous data link control (SDLC), carrier-sense multi-access with collision detection (CSMA/CD), and user definable (non-standard) protocols. The flexibility in defining non-standard protocols provides the ability to retrofit new products into older serial technologies, as well as the development of proprietary interconnect schemes for serial backplane environments. The GSC operates in full duplex or half-duplex mode and performs cyclic redundancy checking (CRC) for 16 or 32 bits. Data encoding is in Manchester, NRZI or NRZ formats. The GSC may be accessed directly by the processor of the microcontroller or through a direct memory access (DMA) channel.

Title: Method of manufacturing whisky
Inventor: EBBUTT LESLIE IAN KERR
IPC: B01D3/00
Filed: 1988-04-29
Abstract: Grain spirit is obtained by the distillation of "wash" in the manufacture of whisky, and it is very important that the spirit should be of constant quality with regard to its taste and smell. One of the most common causes of significant departure from such constant quality is the presence in the spirt of "B" compound which is 2-methyl-3(methyldithio) furan and which imparts a burnt odour to the spirit. This problem is overcome by introducing oxygen into the wash by providing a compressed air supply to the feed pipe (12) to a rectifier (16) of a Coffey still (18). The incidence of "B" compound is thereafter found to be insignificant. <IMAGE>

Title: Stuffing box for underwater well lubricator
Inventor: CORPORATION OTIS ENGINEERING
IPC: E21B33/08
Filed: 1989-01-26
Abstract: An hydraulically actuated stuffing box for use on a lubricator assembly or a grease injector section to seal around flexible line run through the lubricator assembly into an underwater well. The stuffing box has a piston on which control fluid acts, compressing a resilient seal in the stuffing box to seal around the line. The piston is biased to a position not compressing the seal to prevent hydrostatic pressure of the control fluid from compressing the seal to seize the line in deep water. The stuffing box and grease injector section have a through passageway for line. Both have an internal valve, which will automatically prevent surrounding water flow into a well or well outflow into the water when no flexible line is in the passageway.

Title: Shock-start type recording disk reproducing apparatus
Inventor: KOIKE EISHI
IPC: G11B3/095
Filed: 1991-04-24
Abstract: A turn table 2 having a recording disk 5 mounted thereon is normally urged upwardly by a stylus force spring 6 disposed between a lower surface of the turn table and a chassis 1 a of a casing to apply a stylus force to a pickup 10. A weight member 19 is rotatably and eccentrically supported on an inside mounting plate 1c, and an operating claw 20a having a slant surface S formed on a lower surface is fixed to the weight member. When a shock is applied to the weight member externally, the weight member rotates by an inertia force in a plane perpendicular to a rotary shaft 3 of the turn table 2. As a result the slant surface S of the operating claw 20a rides over the upper end of the rotary shaft 3 thereby to press the rotary shaft, together with the turn table downwardly. Thus, the stylus force of the pickup is released allowing the stylus to return to a biased start position. When the weight member returns to an original position by a return spring 21, the operating claw retreats, and the turn table also returns to the upper position restoring the stylus force and enabling reproduction of the disk. <IMAGE>
