Title: Dehydrated frozen vegetables
Inventor: LEWIS VICTOR MARCUS
IPC: A23B7/05
Filed: 1989-10-13
Abstract: A method for preserving vegetables at sub-zero Celsius temperatures is described, which involves partially dehydrating and adding one or more water activity controlling substances to the vegetable product before reducing its temperature. The vegetable product remains flexible and unfrozen at typical frozen food storage temperatures. The water activity of the product is below 1, and is preferably below 0.9, measured at 20 DEG C. Suitable water activity controlling substances are, for example, salts, sugars, and polyhydric alcohols.

Title: Geiger-Muller tubes
Inventor: GAIR SALEM ABRAHAM
IPC: E21B47/01
Filed: 1990-03-05
Abstract: A Geiger-Muller tube designed for use in an environment (for example, mounted on a rock drill) where subjected to mechanical shock and vibration has a tensioned anode wire (1) secured by welding to securement members 21, 24 between first and second mounts (11, 21) and (12, 22) at opposite ends of the tube envelope. The wire tension is adjusted to a high value with a screwible-adjustment means (22, 23, 24) which is locked eg. by spot-weld *25 or by a locking nut, in the adjusted position, so that the natural frequency of vibration of the tensioned wire 1 does not resonate with (and may be much higher than) the frequencies to which the tube is subjected in use. The wire frequency is typically in excess of 400Hz and even 500Hz. The adjustment means (22, 23, 24) may be included in the mount (12, 22) via which the envelope is evacuated and back-filled with the ionizible gas, and a gas-tight seal (30) can be provided around this part of the mount (12, 22), for example by sealing off the gas pump tube. However the adjustment means may be designed into another part of the tube, for example using telescopic parts of the envelope whose sliding junction is made gas tight with a flexible seal, Figs. 6-8 (not shown). <IMAGE>

Title: Disk drive controller.
Inventor: SANDER WENDELL
IPC: G11B20/12
Filed: 1991-05-20
Abstract: A disc drive controller has read post compensation which corrects for peak shift effects on discs with insufficient precompensation. The data is recorded in Manchester (MFM) format and read into circuitry including SCT counter (451) which loads parameters representing a cell with a short-cell (2 unit) following it and LCT counter (453) which loads parameters representing a cell with a long cell (3 or 4 unit) following it. Bound detector 455 counts the number of pulses between transitions and shift registers (457, 459) store the number of pulses generated by the respective counters to enable the bound detector to generate peak shift compensated pulses. The controller has a programmable parameter scheme which makes it possible to read and write 3 1/2 inch variable and fixed speed drives, as well as standard 5 1/4 inch drives. Additionally, there is a plus/minus rate multiplier to correct for symmetry and frequency errors. The use of half clock circuits to provide half clock resolution in the signal being written to and read from the disk is provided with the capability of operating at continuously variable clock speeds and data rates dynamically programmable by the computer. <IMAGE>

Title: The tightening of closures
Inventor: MIDGLEY STEVEN
IPC: B67B1/06
Filed: 1991-09-10
Abstract: An apparatus for tightening closures 24 eg pressure valves or spears, to a predetermined torque in containers 11. The apparatus comprises a motor 2 with a variable speed controller 1, a driving head 3 driven by the motor 2 and shaped to engage lugs 25 in the closure 24 and torque sensing means 6, eg a strain gauge, for sensing the reaction torque of the motor 2. When the sensed torque reaches a predetermined level the motor 2 is stopped. In use a container 11, eg a beer keg, is delivered by conveyor to apparatus which detects its presence, by a position switch. The conveyor is then lowered and the container is held by support bars 10 and gripped firmly by retaining arms 9 which approximately centres the container below driving head 3. Driving head 3 is then lowered, by positioning means 4, and gently engages the closure due to collar (22. fig 2), springs (27, fig 2) and lever (30, fig 2). At this stage the motor may turn slowly or be stopped however the motor may be stated or its speed increased after contact has been made with a proximity switch. The speed is set to a pre-set maximum so that the predetermined torque is reached before maximum speed. <IMAGE>

Title: Artificial angling bait.
Inventor: BARCLAY HOWARD DONALD
IPC: A01K97/04
Filed: 1992-04-03
Abstract: In an artificial angling hook bait, bait substances, that due to their physical nature cannot be mounted on a hook, are contained in an absorbent fibre core which is retained within a membrane of fine mesh which is attached to the fish hook. A small quantity of the bait substance will leak off into the water thereby attracting the fish to the bait. If the fish touches the artificial hook bait, a higher concentration of the bait substance is displaced through the fine mesh membrane into the surrounding water thereby increasing its attractiveness to the fish. <IMAGE>

Title: Mhd generator: converting the chemical energy of methane to electrical energy
Inventor: CARABETTA RALPH ANTHONY
IPC: H02K44/08
Filed: 1993-01-19
Abstract: Methane is thermally decomposed to hydrogen and carbon in a decomposing unit at a temperature not less than about 1200 DEG K and at a pressure at least slightly above atmospheric pressure. Carbon, substantially pure oxygen and a cesium or potassium seed material is transmitted to a combustor which is maintained at a pressure of at least about 50 atmospheres and provide an ionized plasma having a temperature >/= 2900 DEG K. The ionized plasma is accelerated to a velocity not less than about 1000 m/sec and transported through an MHD generator having a magnetic field in the range of from about 4 to about 6 Tesla to generate ac power via the inverter. The ionized plasma is deaccelerated and passed in heat exchange relationship with the methane, and thereafter any cesium or potassium seed material is recovered and transported to the combustor. The hydrogen may power a fuel cell: alternatively the arrangement may be operated for hydrogen and carbon monoxide from the MHD generator to produce methanol. <IMAGE>
