Title: Improvements in or relating to circular knitting machines
IPC: D04B15/88
Filed: 1934-03-26
Abstract: 432,233. Knitting-machines. SPIERS, Ltd., W., XL Works, Walnut Street, SPIERS, E., Rockford, Wimbourne Road, Ventnor Road, and SMITH, H. N., 203, Overton Road, all in Leicester. March 26, 1934, No. 9422. [Class 74 (ii)] In a circular knitting-machine, tensioning means comprises fabric engaging members having opposed surfaces, one or each of which is spirally grooved or ribbed, and between which the fabric passes and is uniformly pulled towards the cylinder centre, by reason of relative rotation between the fabric and the members. The fabric, immediately on leaving the needles, passes between the opposing spiral ribs on the disc 1 and the flared out part 3<a> of a cylinder 3. During circular knitting, the cylinder 3 is stationary, and, by means of differential spur gearing the disc 1 is rotated in the same direction as the needle cylinders, but at twice their speed. During reciprocatory knitting, pawl and ratchet mechanism (not shown) enables both the members 1 and 3, to turn with and at the same speed as, the needle cylinders, during the reverse strokes, and to be respectively driven and held during the forward strokes. To facilitate the passage of different web thicknesses, the part 3<a> is yieldingly urged against the disc 1, by springs 10, but can be retracted by a cam 12 on the main pattern drum, so that when the tensioning means is used in conjunction with ordinary take-up rollers 49, also operated by the cam 12, both may be rendered inoperative during the formation of a pouch. The disc 1 may also be raised and lowered with the top cylinder, through timing mechanism. In a modification, Fig. 5 (not shown) the disc 1 is yieldingly pressed down on the member 3, which is fixed axially, by a spring, or weight-loaded lever. The surfaces may be so made that the spiral rib of one, engages with the spiral groove of the other. When this arrangement is used with rotary cylinders, both the members are stationary during circular knitting whilst in a seamless hosiery machine, one or each may be rotatable with the fabric, and, by means, e.g. of pawl and ratchet mechanism, the member or members may be held stationary in the forward strokes of reciprocatory knitting, and made to rotate during the reverse strokes. The spirals may be continuous or mutilated, and, when inside sinkers are employed, the sinker cup may form one of the opposed tensioning members. The invention is said to be applicable to all types of circular machines. Specifications 15008/00, [Class 74], and 24290/12, [Class 74 (ii)], are referred to.

Title: Hydraulic pressure modulatorp
IPC: B60T8/40
Filed: 1974-03-04
Abstract: 1421703 Pressure modulating valves SOC ANON DBA 4 March 1974 [3 April 1973] 9630/74 Headings F2F and F2V An hydraulic pressure modulator for an antiskid brake circuit comprises a housing 20 provided with a fluid duet 22 having an inlet orifice 23 and an outlet orifice 25 adapted to be connected to a source of variable brake pressure, e.g. a master cylinder 10, and a set of brake actuators 14 respectively, a non-return valve 24 in the duct allowing fluid to flow from the outlet orifice towards the inlet orifice, a control plunger 36 slidable in a bore 32 so as to define therein a modulation chamber 46, and a passage 48 connecting the chamber with the inlet port downstream of the valve 24. The latter is controlled by the plunger so that the plunger is capable of modulating the fluid pressure in the modulation chamber as a function of a variable control force transmitted by a differential driving piston 34 in the stepped bore 32 in which it defines a compression chamber 42 adjacent to that end face of the piston having the larger effective area and a decompression chamber 44 adjacent that end face of the piston having the smaller effective area. A work valve 56 is actuated by the plunger for controlling the fluid flow through the passage 48 the effective area B of the work valve seat being less than the effective area A of the plunger. When the latter has left its idle position and is submitted to the pressure prevailing in the modulation chamber 46. Prestressed resilient means, i.e. springs 50, 52, act on the differential piston for biasing the plunger toward the said idle position in which the work valve is closed and the non-return valve 24 is open. As shown, the one-piece member 30 forming the piston 34 and plunger 36 contains a leakage duct 60, which has mounted therein a calibrated valve 62 allowing fluid to flow only from the chamber 46 to the chamber 44. The valve 18 is operated by an hydraulic assisting circuit comprising a pump 64 connected by a non-return valve 66 to a pressure fluid accumulator 68 which is connected to the decompression chamber 44 via an orifice 70 and to the compression chamber 42 via an orifice 72 and an antiskid valve 74, the latter orifice being also connected to a low-pressure fluid reservoir 78 via an anti-skid valve 76. The valves 74, 76 represent a system of anti-skid solenoid valves operated by signals generated by an anti-skid control device which responds to signals generated by speed sensors and representing the angular motion of at least one wheel 16 of the vehicle.

Title: Method and apparatus for dividing glass sheets
Inventor: LAMBERT MICHEL
IPC: B65G49/06
Filed: 1966-03-04
Abstract: 1,137,893. Dividing glass sheets. GLAVERBEL. 4 March, 1966 [5 March, 1965], No. 9685/66. Heading C1M. In a method of breaking glass sheets along pre-scored lines, one side of the sheet, over an area containing such lines, is subjected to an elastic pressure in excess of any pressure prevailing on the other side of the sheet, while restraining movement of the sheet at the periphery of said area, so that the sheet flexes and breaks. Preferably the sheet is clamped around the whole of the periphery of said area. Pre-scored glass sheets 14 are fed off delivery rolls 26 on to a flexible continuous belt 20 and are conveyed above the perforated top wall 2 of a chamber 1. The chamber is connected to a source of air under pressure and is also vented to atmosphere. As the sheet 14 leaves rolls 26 it contacts a sensing device 41 which initiates the breaking sequence through a control circuit. The sheet is halted above the chamber 1 and then a rigid membrane 32 mounted upon a vertically movable frame is lowered into contact with the sheet thereby rigidly holding the sheet, at its margins only, against the perforated wall 2 and conveyer 20. Air is then introduced into chamber 1 and this causes the sheet 14 to flex away from chamber 1 and thus break along the scored lines. The chamber 1 is then vented to atmosphere, membrane 32 raised and the divided glass sheets conveyed away. Other simpler forms of apparatus are also disclosed in one of which the perforated wall 2 is flexible. The control circuit essentially comprises a magnetic disk rotating at a constant angular velocity on which a signal is recorded when a sensing device detects the leading edge of a glass sheet. This signal is then moved in sequence past a plurality of reading heads which activate circuits controlling the various operations. At the end the signal is erased.

Q., Devon House, Townsend Drive, St. Albans, Hertfordshire, and BENHAM, W. E., 88, The Ridgeway, Golders Green, London. March 29, 1934, Nos. 9858 and 29311. [Classes 39 (i) and 40 (iii)] In a television cathode ray receiver, the area of the spot on the fluorescent screen is modulated in accordance with the incoming picture signals. For dark areas, the spot area is small, and for bright areas it is large. The total intensity of the spot remains constant. The picture signals are applied at M across two series impedances Z1, Z2, connected through condensers C1, C2. The cathode 2 is connected to the midpoint of the condensers C1, C2. The potentials of the cathode shield 3 and the first anode 4 are thus varied oppositely and this is stated to produce a spot of constant total intensity, but of varying diameter. Alternatively, the potential of the screen may be varied while the first and second anodes 4, 5 are maintained constant, or the potential of any two of these three electrodes may be varied. This method of modulation may be combined with speed modulation and/or intensity modulation.
