Patent GB-926857-A (GB)
Abstract: 926,857. Knitting-machines. SDRUZENI PODNIKU TEXTILNIHO STROJIRENSTVI. July 7, 1960 [July 11, 1959], No. 23728/60. Class 74 (2). Yarn is introduced to the needles of a circular machine by a stream of compressed air passing through a nozzle 3 through which the yarn passes and which is positioned so that the yarn extends from the nozzle between two adjacent needles. A body yarn 5 and a reinforcing yarn 6 may pass through the nozzle 3 each being separately fed by its own supply of compressed air. A lower channel 8, 10 coupled by an inlet 15 to an air supply 16 is provided for the body yarn and an upper channel 9, 11 coupled by an inlet 17 to a supply 18 is provided for the reinforcing yarn 6. A cutter blade 61 operated by a lever 58 is positioned adjacent the end of the nozzle to sever the yarns when they are withdrawn. A cam-actuated blade 43 serving to operate a needle raising slide also moves two cam segments 32, 33 on a lever 36. Prior to feeding the yarn the segment 32 lifts a guide eye 55 to draw extra body yarn which passes freely through a disc tensioner which is simultaneously opened by a blade 34 also raised by cam 32. The blade 43 is then moved to cause the blade 34 and eye 55 to be lowered and simultaneously to open the air supply valve 21 to the supply pipe 16, Fig. 4. The compressed air passing out through channel 10 offers the yarn to the needles which take and knit it whereafter the segment 33 again raises the blade 34 and eye 55 and simultaneously shuts off the air supply. The reinforcing yarn is fed by a stream of compressed air supplied under the control of a valve operated by a rod 51. On withdrawal of the yarns the cutter 61 is operated by rod 63 to sever both of them. When the reinforcing yarn is partially knitted over courses the cutter is operated only sufficiently to sever the reinforcing yarn.

Title: Vacuum cleaner with recirculated exhaust air
Inventor: EDGINTON BENJAMIN
IPC: A47L9/08
Filed: 1993-06-16
Abstract: A vacuum cleaner in which exhaust air is recirculated to the cleaning head comprises flexible pipes or hose 3, arranged to return contaminated air from the dust bag to nozzles 4 directed on to the carpet (or object to be cleaned) at an inward angle where it assists in removing dust arid dirt which is then drawn into the cleaner. Alternatively the pressurised air can be returned through the vacuum cleaner housing to the front of the machine and down on to the carpet via holes 15 (Fig. 5). In both methods most of the air and dust which comes from the dust bag is retained within the cleaner and returned to the dust bag, thus reducing contamination and odour. <IMAGE>

Title: Detection of counterfeit bank notes
Inventor: HOPWOOD JOHN GEOFFREY
IPC: G07D7/00
Filed: 1994-07-12
Abstract: Detecting counterfeit bank notes is achieved by directing ultraviolet light at a sample from a source (104) and measuring the level of ultraviolet light reflected from the sample using a first photocell (105) and the amount of fluorescent light generated by the sample using a second photocell (106). The detected levels are compared with reference levels and only if both reflective and fluorescent criteria are satisfied is the note declared genuine. The sample, during test, is supported on a glass plate (102). The apparatus uses the value of the intensity of light reflected from the glass plate (in the absence of a sample) as a basis for producing at least one reference level against which a subsequent comparison can be made. <IMAGE>

IPC: H03M1/38
Filed: 1994-04-05
Abstract: An n-bit analog processing circuit constructed with network swappers has n stages and an input port for inpulling an analog signal to be processed. Each of the n-stages includes first and second reference input ports (IR1, IR2), at least one swappable network (NWK1, NWK2) having first and second terminals, and a switching element (SW1, SW2) that is responsive to a digital input signal (D) for varying a connectivity of the first and second terminals with respect to the first and second reference input ports. Each of the n networks has a primary electrical characteristic that is binarily weighted with respect to others of the networks. The primary electrical characteristic may be resistance, superconductance, time delay, permeability, electrical or optical conductor length, and/or winding turns. A characteristic of an analog signal appearing at an output port is a function of an analog signal applied between the first and second reference input ports of a most significant stage, and is also a function of an n-bit digital signal (binary or Gray code) that is applied to the n-stages. <IMAGE>
