Title: Method and apparatus for the drawing of flat glass
IPC: C03B15/02
Filed: 1968-01-05
Abstract: A process for the manufacture of sheet glass by the updrawing of a continuous ribbon from a bath of molten glass comprises imparting transverse to the ribbon a to-and-fro motion to the gases forming the atmosphere on at least one side of the ribbon in at least one portion of the drawing chamber whilst the ribbon is in vertical motion. This motion which is substantially horizontal, is imparted to the gases by means located in the desired part of the drawing chamber on both sides of the ribbon or on that side of the ribbon downstream of the direction of feed of molten glass. In one embodiment, Fig. 1, an asbestos plate 12 or 121 mounted on wires 13, 131 is located on each side of a glass ribbon 2. The ends of the wires are attached to reversibly rotatable drums 17, 14 or 171, 141. In a preferred embodiment a double-headed gas ejector 51 (Fig. 5) is situated centrally of a ribbon 41 on the " downstream " side only. Each head of the gas ejector is separately connected to a gas source, which includes its own heat-exchanger 53 located in the catch pan 47, and through valves and a timing mechanism is operated alternately so that the desired gas movement is produced. Preferably, reversals are made every 4 or 5 seconds. By so regulating the pressure of the gas supplied, the air movement can be affected on the side not containing the ejector. In place of the plates 12, 121 there could be used a fan situated on each side of the ribbon. In further embodiments up to two single-headed ejectors are used on each side of the ribbon, the ejectors being positioned adjacent the marginal edges of the ribbon.

Title: Master cylinder
IPC: B60T11/16
Filed: 1968-01-18
Abstract: In a master cylinder for a brake system, wear on the piston seal 11 due to its passing over the compensating bore 27, is equalized over its entire circumference by arranging for the piston to be rotated slightly about its longitudinal axis during movement of the pushrod. In one arrangement, Fig. 1, tongues 6, 7 co-operate with teeth 9 on the piston to rotate the piston slightly as the tongues are flattened against the cylinder end wall by the piston returning to its inoperative position. In another arrangement, Fig. 7, the end of the pushrod 1 is enclosed by a member 16 which frictionally engages the piston 2 when the slack S has been taken up and is rotated by the torque produced by compression of a spring 17 the ends of which are rigidly attached to the pushrod and the member 16 respectively. In a modification, Figs. 8 and 9 (not shown), the rotation is produced by a pin (21) through the pushrod engages axially inclined slots (22) in an enclosing member (19). In another arrangement, Fig. 6 (not shown), the pushrod carries a screw having a long lead of thread to produce the rotation.

Title: Process and apparatus for fluid treatment of substrate
IPC: D06B3/12
Filed: 1968-02-02
Abstract: A web of textile material is treated with a liquid by being passed continuously through a chamber in which a sonically propagated gaseous dispersion of the liquid has been produced. The liquid may be dye, size or resin. The treatment chamber 10 is framed within a vessel 12 having vertical side walls 28 and lower conically tapered side-walls 28a terminating in a trough 30. A sonic generator 24 is mounted on a cross-plate 26 at the level of junction between walls 28a and walls 28. A discharge chamber 40 is formed immediately above the generator 24 by a baffle plate 38 and a horizontal series of bafflestrips 42 to open to the chamber 10. The upper end of chamber 10 is sealed by three rolls 14, 16, 18, rolls 14, 16 forming an entry nip for a web W and rolls 16, 18 an exit nip. The web W is fed through nip 14, 16 into chamber 10 and follows a sinusoidal path alternately over upper rolls 20 and lower rolls 22 axially leaving through nip 16, 18. A predetermined mixture of air and liquid is fed to the generator 24 which propagates a gaseous dispersion containing particles in the size range 5-10 microns, the dispersion passing around baffle 38 into chamber 10. The spent gas is exhausted via chamber 40. Any gas contacting the side walls 28a condenses and runs into trough 30. To prevent condensation on side walls 28 they are covered with a fine wire meshing 50 and air from blowers 48 is blown into the chamber to form a film over those walls. The liquid has a solids concentration of up to 33% by wt.

Title: Method of and apparatus for measuring the direct current supplied by a rectifier arrangement fed by an alternator
IPC: G01R31/34
Filed: 1968-12-20
Abstract: The direct current supplied by a rotaryrectifier arrangement which is fed from an alternator is measured by detecting the magnitude of a harmonic component of the flux created by the alternator armature reaction field. One or more coils 5 are located between the stator poles 8, 9 of the three-phase alternator to detect the armature reaction flux, and a filter tuned circuit or tuned amplifier selects a particular harmonic of the output of the coil(s) for measurement on a voltmeter. The measured voltage will be proportional to the required current if diode rectifiers are used, but needs to be corrected as a function of firing angle if thyristors are used.

Title: Apparatus for making hollow plastic articles from thermoplastic sheet material
IPC: B29C51/34
Filed: 1970-02-13
Abstract: False bottomed containers are made by first drawing a heat-softened thermoplastic sheet into a cavity 3, the base of which is defined by transversely reciprocable elements 2 and a punch 4 around the upper end of which are slidably located a series of concentric sleeves 7. The punch and sleeves are then raised to the position shown in Fig. 2 to move the bottom of the container formed by the drawing operation upwardly and to produce a downwardly extending divergent skirt between the upper surfaces of the sleeves and the inner surfaces of the elements 2. The sleeves 7 are supported in their lowest positions by three stepped segments 6 equiangularly located around the cavity 5 which guides the punch and are sequentially raised starting with the innermost, to their operative positions by three stepped segments 8 on the punch, the segments 8 being received between the segments 6 (see Figs. 3 and 4, not shown). The uppermost position of the sleeves is determined by a rod fixed to the tool member 1 and received in an axial slot in the sleeves (see Fig. 6 not shown) and the sleeves are returned to their lowest positions after the forming operation by a pin carried by the punch (see Fig. 5, not shown). The initial forming operation may be a plugassisted blow or vacuum forming operation. (For Figures see next page.)

Title: Knitting machine, and in particular flat knitting machine
IPC: D04B15/36
Filed: 1974-02-16
Abstract: In a knitting machine of the type in which needle controlling butts are transversely movable in a tricked needle bed so as to be moved toward and away from needle displacing lock parts, and in which jacks are displaceable into a latching position in which they hold the needle controlling butts in a depressed position relative to said lock parts, the jacks are adapted to be retracted from the latching position by other lock parts acting on jack control butts. The invention proposes that the control butt of each jack constitutes itself a magnetic armature, is mounted for limited longitudinal displacement relative to the jack, and projects into a control lock passageway in which its movement is governed by magnetic controls. Each jack control butt preferably is provided on a slide mounted for longitudinal displacement in the jack, the maximum range of this displacement being smaller than the maximum corresponding displacement of the control lock passageway. The control lock passageway includes branches into which the jack control butts are magnetically directed.
