Title: Method of making stretchable woven fabrics
IPC: D06C3/00
Filed: 1951-02-28
Abstract: 685,412. Stretchable woven fabics. UNITED STATES RUBBER CO. Feb. 28, 1951. [May 23,1950] No. 4857/51. Class 140. In making a two-way stretch fabric consisting of a non-elastic woven sheet having a rubber backing bonded thereto, a woven fabric 10, Figs. 4, 5, of cotton, rayon, wool, or nylon in open twill, satin or other weave with a smooth or pile surface and having heat-shrinkable weft yarns is unwound from roll 13 and the selvage edges are picked up by tenter chains 15 of which one run is guided by tracks 18 to mechanically limit the weft-wise shrinkage of the fabric to a controlled amount. The fabric is treated with wet stream through pipe 19, and passes through heating chamber 20, and the shrunk fabric is coated with a film 21 of natural or synthetic rubber latex on one face by spreader 22. The coated fabric passes round rolls 23, 23<SP>1</SP> through partial drier 24, to the nip of a pair of rolls 25, Fig. 6, where it is secured by the tacky latex film to endless rubber belt 26, and the rubber belt with adherent fabric passes around guide rolls 27 through drier 28 to dry the tacky film. The portion 26<SP>1</SP> of belt 26 between rolls 29 and 25 is highly stretched, so that the predetermined amount of relaxation thereof during passage about rolls 27 causes warp-wise contraction of the fabric. The longitudinally and transversely contracted fabric is stripped from the belt and wound onto take-up roll 32. The coated fabric may be further heated, to cure and vulcanise the rubber film, in a festoon drier, and the fabric may finally be mechanically stretched transversely, by passage through an expander, to render the heat-shrunk yarns unable to hold the fabric in shrunken weft-wise state. Specification 648,644 is referred to.

Title: Improvements in engine turning gear for starting internal combustion engines
IPC: F02N15/06
Filed: 1943-07-15
Abstract: 569,063. Turning-gear. CROSS, R C. July 15, 1943, No. 5126/45. Divided out of 569,020. [Class 7 (v)] A two-stroke engine comprises an oval &c. piston and cylinder adapted to prevent rotation of the piston, a one-way rotary clutch coaxial with the piston, and a helically-splined shaft fixed to the driving member of the clutch and passing axially through the piston which is formed with splines co-operating with the splines on the shaft. An oval cylinder 2 houses a piston 1 slidable along a splined shaft 7 and adapted to be rotated as splines on the bush 9 of the piston engage the splined shaft 7. A coil spring 17 encircles a sleeve 10 surrounding the bush 9 and returns the piston to the inner end of the cylinder whence the ignited charge forces it outwards again. An auxiliary starting carburetter 21 supplies combustible mixture to both the combustion chamber and a pre-compression chamber below the piston. When sufficient pressure has been built up in the combustion chamber to displace the piston a small distance outwards, the piston movement closes the ignition circuit. Alternatively, a fluid-pressure switch may control the ignition. As the piston moves outwards it uncovers an inlet port 12 connected by a transfer passage 13 to a port 14 in the pre-compression chamber and the charge therein is forced into the combustion chamber until the skirt of the piston closes the port 14. The remaining charge acts as a buffer to check the piston movement until a port 14a in the piston skirt uncovers the port 14. The shaft 7 is rigid with the driving. member 29 of a one-way clutch, the driven member 30 of which is connected through a friction clutch 34 ... 36 to a helical dog clutch 40, 37 and the driven member 37 of this clutch is splined to a second dog clutch 38 adapted to engage a larger internal-combustion engine to start it.

A device for use with a safeload indicator as described in Specifications 723,070 and 978,822 converts the latter for use with cranes having telescopically extensible jibs. Changes in jib angle are communicated to a lever 9, Fig. 1, by links 1, 1a, a cam 2 and a lever 5 carrying a camfollower 7. Changes in jib length are transferred to the lever 9 through links 10, 10a, a cam 11, a lever 13 and a crosshead 16 which slides in a slot 18. Movements of the lever 9 are applied to the jib angle compensating link of a safe load indicator of the type referred to above by a cable 22. In a second embodiment, Fig. 2, a bellcrank 50, 59 is pivoted about a pin 51 by changes of jib angle through links 31, 31a, cam 32, levers 35, 53 and a crosshead 52. Telescopic movements of the jib are transferred to the bell-crank 50, 59 by links 41, 41a, a cam 42, levers 44, 47 and a cable 49 which slides the crosshead 52 up and down the limb 50 of the bell-crank. The movements of the bell-crank are fed to the jib angle compensating link of a safe load indicator by a link 60. Fig. 4 show a device which is used in conjunction with one of the devices described with reference to Figs. 1, 2. It is intended for use with a crane which is luffed by an hydraulic cam and produces a correction which is proportional to the ram moment arm about the jib foot pin of the crane. The hydraulic pressure in the ram is applied to a lever 79 through a spring-loaded piston 73 and a lever 76, whilst change of ram angle, which is proportional to change of jib angle, is fed to the lever 79 through a rod 80, cam 81 and bellcrank 83. The movements of this lever are transmitted through a rod 90 to a device as described above.

Abstract: 733,687. Switching control. SOLA ELECTRIC CO. March 3, 1952 [March 16, 1951], No. 5489/52. Class 38 (4). A device for producing a large current change in a control circuit in response to a slight deviation from a given voltage level of a constant frequency voltage supply, comprises a high leakage transformer 11 having its primary winding 12 energized from the supply and its secondary winding 13 connected through a condenser 16 to a current-responsive device, such as a relay coil 17. The capacity of the condenser is such that it resonates with the leakage inductance of the transformer (which varies with primary current and, hence, the supply voltage) at, or near, the given voltage level so that the secondary current is very sensitive to small voltage changes about that level. A resistance 19, which may be variable and which may be shortcircuited by an auxiliary contact 20 of the relay, when in its inoperated condition, is included in the secondary circuit to control the voltage differential of the circuit. Alternatively, the auxiliary contacts may be dispensed with if resistor 19 has a large positive temperature of coefficient. The device may be used for disconnecting a load, or re-connecting it to a stand-by source, upon the voltage of a main supply source falling by a predetermined amount from a given level.
