Title: Improvements in or relating to machines for the manufacture of fabric
IPC: D04H3/12
Filed: 1952-12-16
Abstract: 764,475. Fabrics composed of threads united by adhesives. MOUNSEY, T. Feb. 25, 1954 [Dec. 16, 1952], No. 31814/52. Class 140. A machine for the manufacture of bonded fabric comprises a stationary drum or support means for drawing warp threads along the surfaces of the drum or support, a carrier or creel for spools of weft threads mounted to rotate about the drum or support so as to wind weft threads in a vertically extending spiral or helical form about the drum or support, means for bonding the overlying weft and warp threads together and guiding eyelets or the like, for the weft threads arranged on the creel in a vertically rising helix around the drum or supports so as to ensure correct laying of the weft threads over the warp threads. Four warp beams 24 are supported from a framework 10 to supply warp threads through an expandable ring 23 and a reed 22 to a cylinder 12 having a fan-tailed former 13 attached thereto. A creel 18, mounted to rotate about the former, supports a number of spools 19 for weft threads which pass along guides 20 to eyes 21 which may be at different heights to wind on the cylinder over the warp. Beneath the creel is a ring gear 32 which engages with a gear 31 driven by a shaft 30 in synchronism with the drive of the warp threads from the beams 24 which pass down the former. Cutting knives 29 cut the weft threads, a gap having been left in the warp, and the fabric passes beneath rollers 25, 25a to winding on rollers 28, 28a. Adhesive is applied to the weft threads from a container 33 beneath the creel. A disc 36 dips in the adhesive and has a blade 42 which applies adhesive to the weft threads which pass from the spools 19 under guide rollers to a roller 39 driven by the threads. The roller 39 drives the disc 36 by a gear 38 on the roller in mesh with a gear 37 on the disc. The weft threads then pass under another guide roller to be wrapped round the cylinder 12. A roller 43 maintains the threads in contact with the roller 39. Gaps in the container provide for entry and exit of the threads. One or more heaters which may be infra-red lamps are mounted in the former to dry the fabric. Adhesive may be supplied to the weft threads by means of a jet, or the threads may pass over a perforated cylinder to which adhesive is applied. The fabric need not be cut into strips, but may remain tubular. The fabric may be cut into one or more than two strips.

Title: Method of depositing metal coatings in holes, tubes, cracks, fissures and the like
Inventor: JENKIN WILLIAM CRISPIN
IPC: C23C16/04
Filed: 1964-08-05
Abstract: In a gas plating process of depositing metal on substrates containing holes, crevices, small voids, cavities, or dead end fissures or bores extending therethrough, the substrate is heated to the decomposition temperature of the thermally decomposable plating gas which is subjected to pulsating pressure conditions in which the pressure is alternately and repetitively reduced and increased, the gaseous decomposition products formed being removed during the pressure reduction. The pulsating pressure conditions are effected either by alternately and repetitively creating a vacuum, or by shutting off and on the flow of gas, or by creating sonic waves in the gas, or by the use of moving walls or diaphragms. In the examples the plating gas is nickel carbonyl, iron carbonyl or aluminium triisobutyl which may be mixed with hydrogen, carbon monoxide, carbon dioxide, nitrogen, methane, helium, argon.  The substrates coated may be plaster, carbon coated plaster, brass, copper tubes or balls and ceramic. According to Figure 1 (not shown) the bore (11) of a metal tube is supplied with nickel carbonyl via a conduit (17) hermetically sealed to the bore inlet, the pulsating gas pressure being effected by a solenoid valve (20) or a rotary valve (29).  Waste gases are passed to a condenser via outlet (23).  In a modification Figure 4 (not shown) the plating chamber (50) is connected with an inlet solenoid valve (56) and an outlet solenoid valve (60) connected to a timing switch (62).  According to Figure 5 (not shown) an electrically operated sonic vibrator (80) in dome shaped plating chamber (75) produces the pulsating gas pressure.

[Also in Divisions G4 and H1] Basic logic circuits each comprising, for example, a transistor 3, resistors 4, 7 and capacitors 2, 9 may be coupled together to perform various functions. In a shift register, Fig. 1, pulses applied at input 1 are differentiated and fed to the base of a first transistor 3. Antiphase shift pulses A, B are applied to alternative transistors in the register, and upon shift pulse A going negative coincident with the negative-going pulse derived from differentiating the input, transistor 3 conducts passing a pulse on to transistor 11. This pulse is in turn differentiated and causes transistor 11 to conduct when shift pulse B goes negative. An inhibit gate may be formed by coupling the output of transistor A2, Fig. 4, to the input of transistor A4 and feeding a second input into A3. Information pulses applied to A3 are fed through A4 as described previously except when an inhibit signal is applied to input 20. Under this condition a positive pulse is produced at the input to A4 to cancel the negative pulse from A3. A number of inhibit gates may be combined with single stages to form a full adder, Fig. 6 (see Division G4). In this Figure inhibit gates 101, 104 and single stages 102, 103 form an " exclusive OR " gate. In modifications of the circuit the shift pulses may be fed through diodes, and the capacitive couplings may be replaced by transformer couplings. In a further modification an A.C. polarizing supply may be used for the transistors, in which case the shift pulses may if desired be replaced by a fixed bias.
