Title: Improvements in straight bar knitting machines
IPC: D04B11/00
Filed: 1936-11-10
Abstract: 484,801. Knitting. BLACKBURN & SONS, Ltd., G., START, H. W., and START, E. Nov. 10, 1936, No. 30624. [Class 74 (ii)] To facilitate fashioning on machines of the Cotton type having needles formed with an inturned hook at the tip of the beard for the purpose of producing courses of ladder resisting locking loops, two sets of sinkers one below the other are provided. All the courses are drawn and the ordinary courses are knitted on a set of usual sinkers A while the locking courses are knitted on a supplementary set C mounted below the main set A. The sinkers C are permanently connected to a catch-bar E which gives them the movements necessary for knitting the locking courses and pulls them back out of the way when not required to knit. The sinkers A are operated individually by a slur cock. In knitting a locking course, the new loops are first sunk on the needles H by the sinkers A, the knooking-over bits Fare lowered and the sinkers C are projected to take the loops. When an ordinary course is being knitted the sinkers C are retracted and the knocking-over bits F are raised. To provide for the operation of the various moving parts during the ordinary or locking courses, as the case may be, the operating cams are disposed side by side in pairs on the cam shaft and antifriction rollers on the associated cam levers are moved from one cam of a pair to the other at the necessary intervals. Fashioning is done by transferring ordinary loops and the sinkers C being out of action do not come into contact with the fabric at this time. Specification 463,618 is referred to.

Title: Improvements in electro-magnetic relays
IPC: H01H51/32
Filed: 1924-12-30
Abstract: 244,591. Western Electric Co., Ltd., (Western Electric Co., Inc.). Dec. 30, 1924. Alternating-current relays comprise a reed armature 13, situated at the centre of a magnetic field formed by a permanent magnet having two N pole and two S pole extensions, and one or more coils energized by alternating current which cause the armature to vibrate at the same frequency and actuate a loose contact device on the armature. According to the construction shown in Figs. 1 and 4, a magnet 9 has adjustable extensions 18 - - 21 fixed on its poles, and a single coil 22 provides the alternating field. The armature 13 is adjustably clamped at 15 so that its free vibrating end may have a natural frequency equal to that of the alternating current, and carries a support 26 which loosely supports one end of a tubular contact 27, the other end of which is loosely linked to a fixed eye-member 28. A circuit normally established through members 26, 27, 28 is thus broken or interrupted when the armature vibrates. According to a modification, Fig. 7, the magnet 9 has magnetic members 21, 22 projecting from its poles, and each of these members carries two projecting pole pieces 26, 27 between which the armature 13 vibrates. Coils 25 connected in series are mounted on the members 27 which serve as cores for them. The reed armature 13 of this modification is channelled and its effective length is determined by a clamp adjusted by a screw.

Filed: 1953-11-12
Abstract: 767,012. Fluid pressure pit prop. COAL INDUSTRY (PATENTS), Ltd. Nov. 12,1954 [Nov. 12, 1953], No: 31376/53. Class 20(2) [Also in Group XXIX]  A pit prop comprises two telescopic members 1, 2 between which is formed a variable-volume pressure chamber 10, the telescopic. members 2 constituting a liquid pressure accumulator associated with an externally controllable valve 15 for admitting liquid under pressure from the accumulator to the chamber 10 to extend the prop, a bleed-relief valve being provided for permitting escape of liquid from the chamber 10 to release the prop. In Fig. 1, the outer telescopic prop member 2 is divided by a wall 8 into a lower chamber 9 which constitutes a liquid pressure . accumulator wherein liquid is maintained under pressure by compressed air within a flexible bellows 12, and an upper chamber 10 of variable volume one wall of which is constituted by the inner end 3 of the inner telescopic prop member 1 which forms a liquid reservoir 11. A valve 15, carried by the wall 8, includes a fixed valve seat 21, Fig. 2. against which a ball valve 18 is held by pressure within the accumulator when the prop is out of use. To set the prop against the roof, the ball valve 18 is lifted from the seat 21 by a needle 30 which is in screw-threaded engagement with the wall of the prop for external actuation by rotation of a knob 33, thereby permitting liquid to flow from the chamber 9 into the chamber 10. When a roof load acts upon the props, pressure built up within the chamber 10 forces the ball valve 18 against a seat 17 in a slidable valve block 16 which prevents return of liquid to the chamber 9, and also displaces the block 16 against a spring 22 so that the position of the block 16 is a function of the pressure in the chamber 10. At a predetermined position of the block 16 the ball valve 18 is pushed from the seating 17 by a needle 23 to permit bleedrelief of liquid from the chamber 10 to the chamber 9. The pressure at which bleedrelief occurs is. predetermined by axial adjustment of the needle 23 by means of a screw thread 24. To release the prop a valve 4 between the chamber 10 and reservoir 11, is opened by actuating an external operating knob 7. When setting the prop, the valve 4 may be opened to permit the prop to be first extended by hand from roof to floor, after which the valve 4 is closed and the valve 15 opened. In a modification (Fig. 3, not shown) the bellows 12 is replaced by a floating piston, and an additional pressure relief valve is provided between the chamber 10 and reservoir 11, which in the event of failure of the valve 15 to open sufficiently permits liquid to escape directly to the chamber 11 from the chamber 10 in the event of pressure in the latter rising beyond a predetermined limit. The air pressure point for the accumulator may incorporate a blow-off valve to operate at a predetermined pressure in order to ensure that the pressure in the air chamber 12 does not rise beyond a desired limit
