Patent GB-2074437-A (GB)
Title: Treatment of plant matter
IPC: A23B7/154
Filed: 1981-04-24
Abstract: A wound in plant matter (such as a wound in freshly cut fruit or vegetables or in living plants) is treated by applying to the wound a porous absorbent sheet material impregnated or coated with an intimate mixture of a biostat and/or biocide and, preferably a fungicide, with a latex coagulant such as aluminium sulphate. When the intimate mixture is in the form of a coating, the latter preferably also contains a water-soluble adhesive polymer; in this embodiment the coagulant may be absent. When the method is used for the treatment of freshly harvested banana hands, crown rot and latex staining is substantially reduced.

Title: Controlling conduction of semiconductor device
Inventor: KELLY JAMES GLENTON
IPC: H03K17/695
Filed: 1981-10-22
Abstract: A transformer-coupled drive arrangement (Figure 1) for effecting switched alternate levels of conduction in a semiconductor device e.g. a field effect switching transistor 13 comprises a drive pulse generator 14 of short (1 microsecond) intermittent drive pulses of alternate opposite polarity, a pulse transformer 16 and zener diode means 21 (or a functional equivalent) by which the transformer secondary is coupled to control electrodes 22, 19 of the transistor. For an n-channel enhancement mode F.E.T. and pulse amplitude and zener breakdown voltage equal to the transistor turn-on voltage each generated positive pulse is passed by zener diode 21 and charges the gate capacitance of transistor 13 turning it 'on', the charged gate reverse biasing the zener diode after the drive pulse has ended and maintaining the 'on' state. The next (negative) drive pulse causes zener breakdown of the diode 21 and discharge of gate capacitance, turning off the transistor until the next positive pulse, enabling the transistor to be switched at a relatively slow rate by short pulses and requiring only a simple and inexpensive form of pulse transformer in the circuit. The zener diode means may comprise back-to- back diodes or a combination of other circuit elements having similar threshold conduction characteristics. The arrangement may drive a number of devices synchronously by having a plurality of secondary windings to the transformer, each with a zener diode connection to a control device. <IMAGE>

Title: A lifting mechanism
Inventor: STOILOVA GINKA SIMEONOVA
IPC: B66F9/08
Filed: 1982-02-25
Abstract: A lifting mechanism, for example for use on a fork-lift truck, comprises a carriage (3) which is lifted by hydraulic cylinders (4) acting through a chain and pulley mechanism (5, 6, 7, 8). Each lifting cylinder (4) is mounted on a respective upright (1) of a mast. Extension of each lifting cylinder (4) raises the pulley (7), around which the chain (5) runs. One end of the chain (5) is attached to the upright (1), and the other is attached to a column (2), so that lifting of the pulley (7) causes the column (2) to rise, taking with it the pulley (8). The chain (6) running over the pulley (8) is attached at one end to the upright (1) and at the other to the carriage (3), and lifting of the pulley (8) thus raises the carriage (3). The velocity ratio between the lifting cylinders (4) and the carriage (3) is 1:4. The cylinders (4) are mounted at the upper region of the mast, which enables wheels (9) of the truck to be positioned relatively close together. <IMAGE>

For the second fields, with switch (39) set to B, when the right or left diagonal is detected, a logic circuit section (60 to 66) converts the video signal (41) into a signal (40) in which a line segment in one of the cells at the right or left diagonal is displaced to the right or left by a half dot period. For the first fields (A), no interpolation is made, and the line segments are delayed by one dot (33) corresponding to unshifted segments in (B) field. <IMAGE>

Title: Tape transport apparatus and method
Inventor: M D ALAYER DE COSTEMORE D ARC
IPC: G01B7/04
Filed: 1982-07-16
Abstract: In the transfer of a web from reel to reel in a web/reel assembly respective speed detectors (56,58) generate electrical pulses at rates proportional to their reel speeds for monitoring the web movement. The time to produce a given number of pulses from each reel is determined repetitively and is utilised to provide ratios of the speeds of the reels. From these ratios, and from other parameters characterising the type of web/reel assembly, a series of discrete web positions are determined while the web is being transferred. A display (68) of the web position is operated by means that provide a continuously changing indication of tape position in terms of time between these discrete web positions, the indication being synchronised with successively determined discrete web positions by comparing the indication with a determined web position and advancing or retarding the rate of change of indication in dependence upon the difference. <IMAGE>

Title: Coal slurry drying and deoxygenating process for coal liquefaction
Inventor: VAUX GEORGE R DE
IPC: C10G1/00
Filed: 1983-10-20
Abstract: A process for drying and deoxygenating coal-oil slurry prior to liquefaction of the coal is disclosed. In the process, the coal generally having a particle size of 30-375 mesh (U.S. Sieve Series) is mixed with a slurrying oil generally derived from a coal liquefaction process at 230-650 DEG F (110-343 DEG C) mixing temperature and generally 0-150 psig (0-10.3 bar gauge) pressure. During the mixing step, moisture in the coal is evolved generally to less than 3.0 W% moisture remaining, along with substantial removal of the oxygen contained in the coal. The process produces a dried more reactive coal slurry for feed to a coal liquefaction process for achieving increased conversion of the coal and producing more desirable low boiling hydrocarbon liquid products.
