Abstract: 499,573. Relooping-needles. KANFER, A., and SCHLESINGER, S. June 23, 1938, No. 18673. Convention date, June 23, 1937. [Class 112] A reciprocating relooping - needle for knitted goods is moved in one direction by vacuum action and is returned by resilient means which is stressed during the movement under vacuum. The reciprocating pump comprises a cylinder 1, connected by a flexible pipe to the needle holder, with a piston 2 carried slidably on a piston rod 4 between an adjustable stop 8 and a valve member 6. The piston 2 has holes 5 which are closed by the valve 6 during the upstroke to create a vacuum and are opened at the beginning of the downstroke owing to friction holding the piston stationary until it is engaged by the stop 8. The stroke of the piston is varied by means of the stop 8. The needle is attached to a piston sliding in its holder and spring-pressed to its extended position, from which it is retracted by the vacuum created during the upward stroke of the pump piston ; a light buffer spring is provided in the needle cylinder to cushion the action of the main spring.

Title: Improvements relating to apparatus for guiding travelling webs
IPC: D21F1/36
Filed: 1963-05-14
Abstract: 973,548. Feeding webs. INDUSTRIAL OVENS Inc. May 14, 1963 [Oct. 8, 1962], No. 19098/63. Heading B6B. Transverse web guiding apparatus comprises a pair of guide rollers 11, 12 supported as cantilevers and arranged so that one edge part of the web 13 can pass between them. The rollers are carried on a mounting 50 with their axes skew to each other. The mounting 50 has a link mechanism 24, 31 and gear mechanism 45, 46 by which it can be rocked to and fro so that the rollers move about an axis between them from one position in which one roller is above the other, as shown in Fig. 1, to a second position in which they are side by side. The skew of the rollers is such that their fixed ends angularly lead their free ends as they move from their first position, Fig. 1, towards their second position, Fig. 7 (not shown), and their free ends angularly lead their fixed ends as they move back from their second position towards their first position. The mechanisms 24, 31, 45, 46 which are operated by a fluid pressure device 21, reciprocate the mounting 50 in a direction away from and towards the free ends of the rollers 11, 12 as it rocks to move the rollers from the first position to the second position and back again respectively. An edge sensing mechanism, illustrated in more detail in Fig. 15 (not shown) comprises a tube 55 which has a slot 56 supplied with low-pressure air which operates a pneumatic control device which in turn controls the fluid pressure device 21. In a modification, Fig. 14 (not shown), the link mechanism 24, 31 is modified so that the rollers 11, 12 do not rotate about a fixed axis between them whilst moving from their first position to their second position as above, but rotate about an axis which is displaced angularly as they move from their first to their second position. The control means may be replaced by known mechanical, pneumatic, hydraulic or electronic control means.

Title: Improvements in record players
IPC: G11B3/08
Filed: 1960-06-01
Abstract: 879,787. Gramophones. EBNER, H., [trading as PERPETUUM-EBNER, FABRIK FUR FEINMECHANIK & ELEKTROTECHNIK STEIDINGER & CO. KOMM.-GES]. June 1, 1960 [June 2, 1959], No. 19356/60. Class 40 (2). In a gramophone a pick-up stylus is fed into the starting groove of a record by means of a fixed ramp and a releasable locking device for holding the pick-up prior to release whereby after release the pick-up slides on a roller down the ramp against the edge of the record to determine the position thereof and from that position is then lifted above the level of the record and moved inwardly and lowered into the starting groove of a record. The pick-up is held in the inoperative position at the top of the ramp by a vertical shaft 22 which passes through a triangular extension plate 11 on the pick-up 4. When a control member 13 on the shaft 22 is moved downwardly to release the pick-up, a projection thereon almost immediately registers with the edge of the record. Further downward movement of member 13 causes the lower end of shaft 22 to move a lever 15, Fig. 4, to lift the pick-up arm so that the stylus is raised above the record surface by means of a pin 20 and plate 21. When the control member 13 is then rotated to a stop 31 for one particular speed of rotation of the turn-table or to another stop 32 for another speed of rotation, the lever 15 is swung horizontally, Fig. 5, to move the stylus over the starting groove of the record. Releasing control member 13 causes the stylus to be lowered into the starting groove. The control member 13 effects a change of speed by means of a plate 23 on the shaft 22, the rotation of which causes a pin 34 thereon to move a lever 33 carrying friction pulleys 39 coupled by a belt to a motor shaft 36, so that one or other of the pulleys engage the rim of a jockey pulley 42 driving the rim of the turn-table 44.

Title: Power steering mechanism for vehicles
IPC: B62D5/10
Filed: 1945-07-30
Abstract: 596,558. Power steering for motor vehicles. BENDIX AVIATION CORPORATION. July 30, 1945, No. 19524. Convention date, June 22, 1944. [Class 79 (v)] A means for steering a vehicle manually or by power comprises a tie rod operable by the steering drop arm and also by a pressure differential motor controlled by a valve, the linkage interconnecting' the valve, motor, drop arm and tie rod being arranged to effect energisation of the motor when the force necessary to move the wheels exceeds a predetermined value. Fig 2 shows a tie rod 14 pivotally connected at 32 to a steering drop arm 22. The tie rod is connected to the steering wheels by rods 16, 18. The connection between the drop arm and the rod is effected by cups 34, 36, Fig. 3, forced together by compression springs 42, 44 loaded to about 120 lbs. The free end of the tie rod is connected to an arm 88 which is connected to a tube 82 which is in turn connected to the piston rod 56 of the servo motor 48. A second link 92 connected to the drop arm is connected to a rod 86 bearing in the tube 82 by an arm 90. This rod operates a valve member within the piston rod. The valve 64, Fig. 5, is slidable within a piston rod 56 and is connected by ,a tube 66, 68 to the induction system. As shown by Fig. 5 the piston 52 is in the neutral position, i.e., when the road wheels are in the straight ahead position.' The piston rod is provided with two ports 58, 60 which communicate with the chambers 118, 120. The valve member is provided with two ducts 72, 74. As shown in the neutral position both chambers 118, 120 are vented to atmosphere via their respective ports 58, 72 and 60. When the force on the steering arm 22 exceeds a pre-determined amount, e.g., the force of 120 lbs. relative movement between the arms 88, 90 will take place by virtue of the spring connection at 32. Hence the rod 102 and valve member 64 will move relatively to the piston rod 56. As shown in Fig. 6, port 58 will then communicate with the engine suction via port 74 thus creating a vacuum in chamber 118, in consequence allowing the piston to move to the left. This movement is transmitted to the road wheels with a follow-up motion. A similar movement of the piston to the right reverses the direction of the vehicles turn.

Title: Improvements in or relating to methods of treating cylinder liners for internal combustion engines to protect them against cavitation erosion
Inventor: WOOLCOTT ARTHUR JOHN
IPC: C23C2/12
Filed: 1963-05-17
Abstract: Grey cast iron or other ferrous metal wet cylinder liner is treated to reduce cavitation erosion by dipping it in a first aluminium metal or alloy (e.g. containing Zn or Si) bath at a temperature sufficiently high to commence bonding of aluminium to the liner surface, e.g. at 680-750 DEG  C., transferring the liner to a second aluminium bath at a temperature of 850-910 DEG C. to complete bonding and austenitize the ferrous metal and quenching the liner in a third aluminium bath at a temperature e.g. 530-700 DEG C. which retains the microstructure of the iron free of discrete ferrite areas e.g. as martensite, bainite, or sorbite.  The liner is preferably transferred from the first to the second bath within 5 seconds or in an inert atmosphere to avoid oxidation of the liquid aluminium envelope and prevent undue cooling.
