Title: Improvements relating to the handling of hosiery
Inventor: HODGES MICHAEL JOHN
IPC: D05B23/00
Filed: 1990-02-15
Abstract: A hose blank (B) is mounted on a hose carrier or loader (11) of a toe closer (T) by hanging the welt end of the blank on an expandable holder (10) while the holder is in a collapsed state, the holder (10) is expanded to stretch open the welt end and thereby positively retain it on the holder, and the remainder of the blank (B) is gathered into a suction chamber (14) forming a pant of the holder. The holder is then displaced toward the carrier (11) and when the holder is opposite an end of the carrier (11) the expanded part of the holder and the opened welt end are moved forward to dispose them about an end portion of the carrier (11), suction is released from the said chamber (14), and thereafter the holder is retracted to disengage it from the welt end while the welt end is prevented from slipping off the carrier (11). <IMAGE>

Filed: 1990-03-15
Abstract: An object 12, as shown a camera zoom lens ring, carries a pattern 18 which is detected by a non-contact sensor 22 to measure the amount of movement of the ring 12. When the ring is to be brought to a halt, the drive 16 remains energised for a predetermined time after the sensor 22 has detected the boundary between two stripes of the pattern 18. In this way the ring 12 is stopped at a position in which the sensor 22 is looking at the centre of a stripe rather than at the boundary between two stripes which might give rise to error. …<IMAGE>…

Title: Exercise rowing machine
Inventor: EVANS HAROLD RONALD
IPC: A63B21/02
Filed: 1991-05-30
Abstract: A rowing machine on which the user does not sit, comprises a base frame with structure supporting an elevated pivot point for an oar lever, which is fitted with footrests at its lower end and hand grips at its upper end and supplied with means to pivot between the said ends, together with means to resist movement of the oar. In use, the exerciser sits on a chair, the machine before him, with his feet on the footrests which he will push forward whilst pulling the upper part of the oar towards himself against resistance, to simulate the action of rowing. The return stroke is unresisted and the machine is stable in use because the pull on the upper oar is counterbalanced by the weight of force in the opposite direction. <IMAGE>

Title: Electricity generating system
Inventor: MOODY RODNEY LEE
IPC: F02B63/04
Filed: 1991-07-17
Abstract: An electricity generating system includes a water tank 31 with electric heating elements (21, Fig. 4), connected to the water cooling system of an engine 12, which is heated by excess output of the system. Power in excess of that required by a load 5, which is generated by a wind turbine driven generator 2, runs up a flywheel 6 and further excess is absorbed in the tank 31. A fan (19, Fig. 4) associated with a radiator (17) connected to the tank 31 may be operated to dissipate further excess power. When the load requirements exceed the output of the generators 2 and 7 the engine 12 operates the generator 13. <IMAGE>

Title: Electrochemical cells with complex of sulphur trioxide and tertiary amine polymer as cathode
Inventor: GILMOUR ALEXANDER
IPC: H01M10/05
Filed: 1992-04-03
Abstract: Electrochemical cells of the non-aqueous type have a cathode composition consisting of a solid complex of sulphur trioxide and a polymeric tertiary amine eg. polyvinyl pyridine or polymethyl pyrrole. High energy density is achieved by virtue of the high EMF generated in a cell which has an alkali or an alkaline earth metal as the anode. The compositions are especially suitable for secondary cells since the micro-structure of the polymeric complex is essentially maintained after the incorporation of metal ions. The utilisation of sulphur trioxide as a solid complex obviates the presence of the highly corrosive liquid material in contact with the alkali or alkaline earth metal anode and the cell container and results in a battery system having long storage and service life.

Title: Scintillation detection
Inventor: WILLIAMS JOHN JAY
IPC: G01T1/20
Filed: 1992-04-09
Abstract: A scintillation detector such as a gamma camera for nuclear medicine comprises a scintillation crystal (1) hermetically sealed in an enclosure (2) comprising a glass wall (3) to which an aluminium cap (4) is sealed (6). The enclosure is supported by a grounded tub (7) which acts as a radiation and light shield. An array of photomultiplier tubes (5) is on the glass (3). The cathodes (c) of the tubes are at -HV relative to ground. The enclosure (2) is electrically isolated from the tub (7) and ground by a sheet (10) of insulative material and the cap (4) is also coupled to -HV. This reduces the potential difference across the glass wall (3) and prevents the production of unwanted scintillation in the glass (3). <IMAGE>

Filed: 1992-07-02
Abstract: A polyethylene film having 70 to 100 mole % ethylene units is heat bonded to a metal sheet provided with a layer of hydrated chromium oxide, and possibly a layer of metallic chromium under the oxide layer. The laminated metal sheet is then rapidly quenched, and the polyethylene laminate is irradiated with an electron beam, gamma rays, or X-rays. Alternatively, the polyethylene film may be irradiated prior to lamination.

Title: Multi-deck sieving machine with deck selector facility
Inventor: COWPER GERALD
IPC: B07B1/46
Filed: 1993-03-24
Abstract: A multi-deck vibratory type sieving machine for sieving a range of sizes of granular material has a vibratory body 10 provided with two or more mesh sieve decks 11, 12, 13 each of different size mesh aperture, arranged one above another in order of mesh aperture size with the smaller aperture sizes positioned uppermost. The granular material to be sieved is guided directly onto the selected sieve deck from inlet chute 24 via ducts 14 - 16 and diverted valves 21, 22. A vibratory drive mechanism 17 vibrates the vibratory body and sieve decks to effect the sieving process. Particles which do not pass through the selected sieve deck are discharged at outlet 25. Particles which pass through the selected sieve deck and any lower deck are discharged at outlet 26. Manual deck removal and replacement is obviated because a change of sieve deck is achieved by selection within the machine. <IMAGE>

Patent GB-934430-A (GB)
Abstract: 934,430. Gyromagnetic compass systems. SPERRY RAND CORPORATION. March 23, 1962 [April 14, 1961], No. 11164/62. Class 40 (1). In a gyromagnetic compass system wherein a gyro 181 (Fig. 3) is slaved to a flux valve compass 10<1>, the long term differences between the gyro and the flux valve are eliminated by utilizing the difference signal developed in the rotor of synchro 16<1>, whose stator is electrically connected to the flux valve 10<1> and whose rotor is mechanically connected to the gyro 18<1>, to energize a torquer motor 22<1> attached to the gyro, the heading signal being obtained from pick-off 26. When the system is first energized, a large difference may occur which is eliminated by differential synchros 12<1>, 281 whose rotors are driven in opposite directions by a knob 14<1>, whereby the output signal from synchro 161 is eliminated, and the heading signal from pick-off 26<1> has the difference angle superimposed on it by synchro 28<1>. In a modification the rotors of synchros 121, 281 are driven in the same direction, but one of the rotors has two leads reversed to reverse its output signal. The differential synchros may be dispensed with, by mechanically linking the stators of synchros 16<1>, 26<1> for rotation in opposite directions. Specification 638,971 is referred to.

Title: Method for amplitude training in a linear power amplifier for a transmitter
Inventor: BOSCOVIC DRAGAN
IPC: H03G3/20
Filed: 1994-03-09
Abstract: In a feedback arrangement of a power amplifier 10, if the difference voltage Vdiff (figure 1) exceeds a certain "clipping" voltage, the output of the amplifier may be non-linear, causing splatter into adjacent channels. The level of input signal which will cause Vdiff to exceed the clipping voltage is found during a training period using romp generator 31. In order to ensure that the romp signal does not itself cause Vdiff to exceed the clipping voltage and cause splatter the romping is repeated with its effective final level being increased in steps until it is detected that the clipping voltage has been reached by Vdiff. In figure 2 attenuator 44 is used to adjust the romp. In figure 1 the variable gain amplifier 15 achieves the result indirectly and after training attenuator 30 compensates for the gain of 15. <IMAGE>
