Title: Improvement in regulating method for free-piston compressors and apparatus for the regulation of such compressors
IPC: F04B31/00
Filed: 1953-01-08
Abstract: 773,391. Compressors. WACHSMUTH, E.A. Jan. 8, 1953, No. 602/53. Class 8(1) In an apparatus for varying the quantity of gaseous fluid delivered per stroke by a free piston compressor which includes a reciprocable piston 39 (Fig. 1)' in a cylinder 32 having an inlet valve 36, a hydraulically operable mechanism for holding the inlet valve open through a portionof the discharge stroke of the piston includes, in combination, hydraulically operable cylinder 61 (Fig. 5) and piston 62 mechanism for holding the inlet valve 36 open (via claws 60, Figs. 1 and 5), a hydraulic impulse giver 42 (Figs. 3 and 5) having means R<SP>1</SP> for varying the time it delivers its impulses, the impulse giver being connected to the hydraulically operable cylinder and piston 61, 62 so that the impulses delivered control the operation of the latter, and means 43 (Fig. 3) responsive to compressor discharge for adjusting the means R<SP>1</SP> for varying the time of delivery of the impulses by the impulse giver 42 to vary such time. The piston 39 is connected by a rocker arm 6 to a shaft 8 on which is mounted a cam 100 for reciprocating the plunger 51 of the impulse giver 42. As the plunger moves up the pressure medium in the space 53 is forced into cylinder 61 against the force of the spring 64 opposing movement of the claws 60 until the clawoperating piston 62 is stopped by the abutment 63 and the valve 36 is held open. As the oblique edge S of the plunger 51 moves upwards over the control port 52, the presure in the system is relieved and the spring 64 withdraws the claw to close the valve 36. The plunger 51 continues its upward movement to expel pressure medium from space 53 through the laterally vented central bore in the plunger and the central port 52 into the space 55 which communicates with the suction space 57 through a throttle gap 56. When the plunger 51 moves down, the suction valve 46 opens. The time at which, during the upper stroke of the plunger, the oblique edge 5 reaches the port 52 depends on the angular position of the plunger and this is controlled by the rack bar R<SP>1</SP>. Gaseous fluid delivered by the compressor is conveyed by a line 89<SP>1</SP> to the device 43 and acts upon spring loaded piston 95, movement of which is transmitted via a lever 88 to the control bar R<SP>1</SP>. The end 90 of the bar is connected to a device which controls an element R governing the delivery of the fuel pump P to the motor cylinder of the compressor (also see Specification 773.392).

Filed: 1928-01-07
Abstract: 283,550. Heurtley, E. S. Jan. 13, 1027, [Convention date]. Repeating from one station to another; duplex telegraphs.-In order to eliminate interference bv earth and like slowly varying currents a receiver or relay is connected to line through a transformer and a. relay is arranged to correct the distortion introduced by the transformer. Thus in a system for repeating signals from a line L<1> to a line L<2> and vice versa, incoming signals from the line L<1> pass through the divided primary P<1>, P<1>, to earth through the artificial line AL<1>, and induce in the secondary S' a current which energizes the relay K<1> causing its armature T<1> to make contact with the marking stop. A current then flows from the source U<1> through earth, relay K<3> and resistances R<11>, R<1>. The potential drop in the resistance R<1> compensates for the eventual falling off of the original induced e.m.f. in the coil S'. The armature T<3> of the relay K<3> relays the signal to the apex V<2> of the bridge associated with the ling L<2>. The milliammeters M, M are differentially wound, and milliammeters M<1>, M<2> also are provided.

IPC: B23C3/32
Filed: 1918-01-10
Abstract: 121,017. Garrard, C. G., and Petersen, J. H. Jan. 10, 1918. Lathes; milling helical surfaces.-Consists in a machine for grooving twist drills, reamers, &c., of the type in which the various movements are controlled by cams on a shaft a at the back of the machine. The cutters, preferably two, are carried by a tail-stock member b and rotated by belts, the member b being reciprocated by a cam d. With this member, a screw e reciprocates in a bush f, which is thus rotated and, through change-gear g, rotates the spindle h carrying the work. When the grooving of the work has been completed, a cam k throws the gear g out and clutches a belt pulley or the like to the spindle h, which is thus rotated rapidly, while the work is cut-off from the stock by a parting-tool l brought into operation by a cam m.

Title: Plated knitted fabrics
Inventor: SLADE ARTHUR
IPC: D04B1/02
Filed: 1955-01-08
Abstract: 782,438. Knitted fabrics. BRITISH NYLON SPINNERS, Ltd. Jan. 2, 1956 [Jan. 8, 1955], No. 648/55. Class 74 (2). The yarn appearing on the outside of an elastic, plated, fabric is one spun from staple fibres of which more than half are of a synthetic linear polymer or polymers; and the yarn plated on the inside is a stretch, continuous filament yarn of a synthetic linear polymer (e.g. a polyamide). The spun yarn is fed at normal tension and the stretch yarn under sufficient tension substantially to remove the crimps or coils therein. The ground yarn may be spun on the silk system substantially wholly from a synthetic linear polyamide. A balanced plating yarn may be formed by doubling two stretch yarns which have been initially twisted in opposite senses. The stretch yarn may be produced by a process involving twisting, setting and back-twisting. In an example, 1¢ denier 5-inch nylon staple fibre containing 15 crimps per inch was spun into 20's cotton count yarn on the silk system.. Two such yarns were folded together with 1/3 the limit of the singler yarns, but in the opposite direction. The folded yarn was then set by subjection to steam at 25 lb per sq. inch for 20 minutes. 30 denier multi-filament nylon continuous filament yarn was twisted to 90 turns per inch, the twist was set and the yarn was then untwisted to zero turns: thus the yarn was converted into stretch twist yarn form. These yarns were fed to a 21-gauge knitting machine, the silk-spun yarn, at normal tension as the ground yarn and the stretch yarn, at such tension as would straighten it, as the plating yarn. The resulting fabric is stated to resemble a cashmere fabric.

Title: Improvements in or relating to tractors
IPC: B62D7/02
Filed: 1962-01-09
Abstract: 986,472. Controlling tractors. C. VAN DER LELY N.V. Jan. 9, 1962 [Jan. 31, 1961], No. 816/62. Heading B7H. In a tractor having a driver's seat 7 mounted thereon so as to be rotatable about a vertical axis to any one of a number of different angular settings two control pedals 69, 70 rotatable with the seat are mounted on arms 71, 72 pivoted on a housing 25 supporting the seat and provided with adjustable studs 92, 92A (Fig. 8) each cooperating with one of two semi-circular coupling elements 86, 87 which encircle the rotational axis of the seat and are each mounted on a bellcrank 95 which is pivoted on the frame 1 of the tractor and is connected by a draw-rod 101 to the braking mechanism of one of driving wheels 2, 3. The ends 89, 91 of the coupling elements 86, 87 overlap so that each stud 92, 92A engages the same coupling element when the seat 7 is rotated through 90 degrees to either side of the straight ahead position but each stud engages the opposite coupling member when the seat is rotated through more than 90 degrees. A spring- loaded pin 80 (Fig. 4) interconnecting the control pedals 69, 70 may be retracted and retained by a pin 81 so that steering may be assisted by differential braking of the wheels 2, 3. Coil springs 110 resiliently support the seat 7 on four parallel arms 16 connected to support plates 23 secured to the housing 25. A cylindrical portion 26 (Fig. 5) of the housing 25 is detachably mounted over a support 29 bolted to the frame 1 and is formed internally with two rims 34, 35 which register with spaced rings 30, 31 on the support 29. A locking pin 115 on the housing 25 engages one of recesses 116 in the ring 30 to retain the seat 7 in a chosen angular setting. A steerable front wheel 4 of the tractor is controlled by levers 36, 37 journalled in universal ball and socket joints at either end of boxshaped portion 27 extending transversely of the housing 25. The levers 36, 37 are connected at their lower ends to U-shaped brackets 46 at either end of a coupling member 47 disposed within the box-shaped portion 27 and connected at its centre by means of a ball and socket joint with a vertical crank pin 58 (Fig. 5) on an arm 59 secured to a vertical shaft 10 journalled in spaced bearing 61 and carrying at its lower end an arm 64 connected by a coupling rod 66 (Fig. 4) with the wheel 4.

Title: Improvements in or relating to the protection of polyphase alternating current or multi-wire direct current circuits or systems against failure of current in the supply lines
IPC: H02H3/13
Filed: 1942-01-20
Abstract: 555,036. Protective cut-out arrangements. NORTHERN ALUMINIUM CO., Ltd., and SIMON, V. Jan. 20. 1942, No. 822. [Class 38 (v)] A protective device for opening a polyphase circuit on failure of current in a line comprises means responsive to the p.d. set-up across a selected portion of that line when currentfailure occurs, to produce operation of an isolating device. In a simple form, Fig. 1 (not shown), the circuit of the hold-on coil of a main contactor controlling a motor includes normally-closed contacts of relay coils which are shunted across the several fuses in the lines so that. if a fuse blows, the corresponding coil will be energized to open the contacts and de-energize tne contactor coil. In Fig. 2, a pair of motors 18 controlled by starters 17 are fed from a supply through main and sub-fuseboards 20, 19, respectively, and from the supply side of 20, connections are led to a sub-board 25 and thence through separate circuits to the supply side of each starter. Each circuit includes a relay coil 24 controlling normally-closed contacts 28 in the circuit of the contactor-coil 29, and contacts 30 closed by a winding 31 in parallel with coil 29. If an open circuit occurs in the shunted part of any of the supply lines, the corresponding winding 24 opens the circuit of 29 to de-energize the motor and the circuit of winding 31 to deenergize the coils 24.

Title: Locking control device
Inventor: REID JAMES HUNTER
IPC: F16B1/04
Filed: 1955-01-11
Abstract: 782,034. Locking rods and levers. REID, S. G., and GOODSON, C. C., [trading as REID ENGINEERING CO.]. Jan. 11, 1955, No. 842/55. Class 80 (3). [Also in Group XXXIII] A locking control device includes a pair of locking members slidably positioned on a bar in gripping relationship therewith and wherein each of the locking members contacts the bar on opposite surfaces thereof, a contacting portion of one locking member being directly opposite a contacting portion of the other locking member. As shown in Fig. 4, which is a control device for an aeroplane throttle, the locking members 30 are slidable along a quadrantshaped bar 28. Each member 30 has a shoe 32 which contacts the top surface of the quadrant and a shoe 34 which contacts the lower surface of the quadrant. The members 30 are connected by means of a pivot pin 42 to a lever 44 which is connected to the throttle and are urged apart by a spring 40. The lever 44 is mounted on a pivot pin 48 which is positioned at the centre of radius of the quadrant bar 28 and on the same pivot pin 48 a lever 22 is mounted. This lever 22 engages the members 30 by means of adjusting screws 56 and when the lever 22 is moved by hand the engagement of the screw 56 pointing in the direction of movement, with the adjacent member 30 causes both members to slide along the quadrant bar and to carry the lever 44 with them to adjust the throttle. If the lever 44 tries to move independently of the lever 22 it causes the members 30 to tilt and wedge against the quadrant bar 28 thus preventing movement of the lever 22. The amount of relative motion between the levers 22 and 44 can be limited by a pin 50 which passes through the lever 22, the lever 44 and the members 30. The apertures through which it passes in the members 30 are oversize to permit a certain amount of lost motion and the pin is mounted in a rubber bushing in the lever 44 to permit the amount of motion between the levers 22 and 44. As an alternative the amount of motion between the two levers can be limited by adjusting screws (not shown) similar to the screws 56. A construction suitable for the control of a sliding seat is shown in Fig. 12. Two members 72 are used each of which is slidable on a bar 64 and each of which has two shoes 92. The members are connected by a pivot pin 74 and are urged into contact with the bar 64 by a spring 76. They are released by a lever 86 which carries a non-circular pin 80 engaging in slots 78 in the members 72. The slots 78 are elongated and are of slightly greater width than the pin 80 and are normally urged to a non-aligned position by the spring 76. Movement of the lever 86 rotates the pin and this moves the slots 78 into alignment and so releases the shoes 92 from the bar 64. As shown, the shoes are an integral part of each member 72 but in a modification the shoes can be independently pivoted members.
