Title: Improvements in and relating to steering mechanism for wheeled vehicles
IPC: B62D7/00
Filed: 1946-02-25
Abstract: 605,920. Motor vehicle steering gear. NUFFIELD MECHANIZATIONS, Ltd., MERRITT, H. E., and CULPIN, C. Feb. 25, 1946, No. 5744. [Classes 79 (iv) and 79 (v)] A vehicle such as an agricultural tractor is provided with interchangeable steerable front wheel assemblies, each comprising a pivoted steering lever which is detachably connected to the drag link and which is connected through a linkage to the steering arm or arms in such a manner that angular movement of the steering lever causes the front wheel or wheels to turn in the same direction as but through a greater angle than the steering lever. With such an arrangement a tractor may be used with either a single front-steering wheel or a two-wheeled swinging front axle, the alternative front wheel arrangements each being mounted on a transverse yoke which can be bolted to the vehicle frame. The twowheeled swinging front axle 1, Figs. 1 and 3, comprises steering arms 6, track rods 4, 5, a bifurcated steering lever 2 pivoted at 3 and whose other arm 7 is detachably connected at 8 to the normal drag link 9. The axle swings about a trunnion pin 18 carried by a bracket 16 detachably secured to the vehicle by bolts 17. By disconnecting ball-joint 8 and removing the trunnion bracket 16 and front yoke 12, the single wheel assembly, Fig. 6, carried by yoke 26, may be bolted in position. The single wheel is steered by steering arm 28, Fig. 5, link 29 and steering lever 32 pivoted at 31 and detachably connected at 33 to the drag link 9. In both cases the layout is such that angular movements of the steering lever 7 or 32 produce movements of the front road wheel(s) of a similar direction, but greater amplitude.

Abstract: 668,175. Plate heat-exchangers BUTLER, J. F., and REBBECK, Sir F. E. March 3, 1949, No. 5807/49. Class 64(iii) A heat-exchanger element (e.g. for use in a recuperator) comprises a series of spaced corrugated plates 41 having the spaces between them closed at the edges of the plates to form a series of through passages B for one fluid, alternating with passages A for the passage of a second fluid, the passages A extending from a port at one end and at one side of the element to a port at the other end and opposite side of the element, a lateral duct 45 co-extensive with the plates 41 communicating with the passages A, and extending from one end of the element so that the fluid flowing through the passages A enters and leaves the element at the same end whilst the element is free at its other end to expand and contract. In the form shown the heatexchange element extends from a header provided with flanges 46, 47 for connection to an external surrounding casing (not shown), the same fluid flowing through the casing, and through the passages B of the element. The header is provided with openings 48, 49 extending through the wall of the surrounding casing for the admission and discharge respectively of fluid to or from the passages A of the element and the duct 45. The end closures for the passages A may comprise strips secured to the corrugated plates 41 by welding or other means or the plates may be shaped to form the closure strips and then secured together. Spacers may be inserted between the plates to prevent deflection due to differences in pressure between the two fluids. Alternatively the spacers may be pressed from the individual plates. The corrugations may be arranged in any direction with respect to the flow of the fluids through the heat-exchanger.

Title: Reduction of cross-talk
IPC: H04B3/32
Filed: 1942-05-01
Abstract: 550,912. Preventing interference. STANDARD TELEPHONES & CABLES, Ltd. May 1, 1942, No. 5884. Convention date, April 26, 1941. [Class 40 (iv)] In a system for neutralizing interference between lines carrying signals covering the same wide band of frequencies, the total band is separated into sub-bands and interferenceneutralizing couplings are made between the respective sub-bands as necessary. In a receiving terminal, Fig. 1, the signals carried by lines 1, 2 are separated into groups by filters F1 ... F8 and the groups are all brought to the same frequency range by apparatus 3. Couplings 6, 7 are arranged as necessary between corresponding groups. The groups are then further sub-divided into smaller groups which are brought by further demodulation to a common frequency range and further couplings 8, 9 are provided as necessary between corresponding small groups. The groups are then separated into channels, at voice frequency by means not shown. In a repeater, Fig. 2 (not shown), a portion of the range is repeated unchanged in the two lines and another portion is divided into frequency ranges which are brought to a common frequency range for the association of the corresponding groups in the two lines via coupling units. The various groups are then restored to their original line frequencies. In another system, Fig. 4, in which the repeaters are fed with power over the transmission circuit, coupling between the respective ranges is effected without any frequency change with the aid of filters F1 ... F4 which are coupled to the lines through condensers 44 for blocking the power currents at a point between repeater stations. Similar arrangements may be provided at a repeater station. In another arrangement, Fig. 3 (not shown), one range of frequencies is used for E-W and another for W-E transmission and coupling is effected at both ends of the system between the receiving circuits only.

Title: Method and apparatus for restarting spinning when a break occurs in an open-end spinning machine
IPC: D01H4/50
Filed: 1975-02-12
Abstract: 1486161 Repair of yarn failure in open-end spinning machines H HIRAI 12 Feb 1975 [13 Feb 1974 14 Feb 1974 15 April 1974] 5889/75 Heading DID The invention relates to the repair of yarn failure in open-end spinning machines of the kind in which a continuously rotating sliver opening roller 6 feeds the sliver to a spinning chamber or rotor 1, the roller 6 being supplied with sliver 7 by feed roll 5 that stops when a yarn breakage occurs. According to the invention the following sequence of events takes place:- (a) The rotor 1 is caused to slow down. (b) When the rotor 1 is rotating slowly the feed roller 5 is rotated for a short period of time to ensure that waste from the continuously rotating opening roller 6 is fed into the rotor 1. (c) The fibre, dust and dirt thus fed into the rotor 1 is removed, preferably by an air blast via a jet orifice 32. (d) Accelerating the rotor 1 back up to speed. (e) Recommencing sliver feed by means of the feed roll 5; and (d) Inserting the broken end of yarn via a spinning tube 15 into the spinning chamber or rotor 1. When a yarn breaks the feed roll 5 stops and then a brake rod 18 is depressed by an operator or by a device 17 that travels along a rail to detect yarn breaks. Through a system of levers, depression of the rod 18 rocks the two-armed lever 24, (Fig. 5) clockwise. This raises a tensioning roller 14 up off a band 12 that then releases its driving pressure on the spindle 13 of the rotor 1 at the same time a brake pad 21 onthe lever 24 presses against the spindle 13 to brake it. The depression of the rod 18 also actuates a valve 22 to cause an air blast to clean out the rotor 1 whilst at the same time it is slowing down under the braking action of the pad 21. In Fig. 7 the broken yarn end is drawn off the package 52, over a freely rotatable thread roll 46, around guide pin 37, pin 39, pin 36 and thence to the spinning tube 15. The package 52 is then accelerated and when a lever 41 is manually actuated it lifts the yarn 55 off the pin 39. During speed-up of the package 52 the thread roll 46 rotates to allow the yarn to move to the left. As the yarn 53 leaves the thread roll 46, as shown in solid lines, the yarn 53 is clamped between a nip roll 43 and a delivery roll 42. At the same time the yarn 53 is caught by the traverse guide 44 and thus a normal traverse take-up operation recommences.

Abstract: 1,169,621. Laminated suede-like material; moulding suede-like sheets. YAMANASHI KASEI KOGYO CO. Ltd. 8 Feb., 1967 [1 June, 1966], No. 6049/67. Headings B4A and B4N. A suede-like material made in imitation of leather comprises a laminated structure consisting of a fabric backing web 10, and a web 11 of thermoplastic material having one face firmly united to one face of the fabric web, the other face of the thermoplastic web comprising a multiplicity of non-uniform variably distorted hair-like filaments integral therewith. In one method of making the material a thermoplastic sheet, e.g. of PVC, polyethylene, or polyvinyl alcohol, is laminated to a woven fabric backing by passage between heated pressure rollers and the product formed is cooled and coiled. In the machine shown the laminated material, comprising a thermoplastic film 11 and a cloth backing 10, is fed from a coil 21, via a preheating roller 22 and radiant heater 23, which melts the surface of the film 11, to the nip between a pressure roller 28 and a heated moulding drum 26. The drum 26 has a multiplicity of minute substantially conical depressions in its surface, into which the molten surface of the film 11 is pressed. The backing 10 and film 11 are partially cooled by a spray of cold water 32 before the laminate is stripped from the drum 26. During this stripping the film 11 tends to stick to the surfaces of the depressions in the drum 26 so that its surface is formed into hair-like filaments. The laminate is then allowed to cool, and is recoiled at 35.
