Patent GB-1304892-A (GB)
IPC: D04B11/22
Filed: 1970-01-30
Abstract: 1304892 Knitting machines SCHELLER TEXTIL MASCHINENFABRIK GmbH Gebr 30 Jan 1970 [26 Sept 1969] 4690/70 Heading D1C In a straight-bar knitting machine, at least one transfer point 19 is carried on a lace bar 67 which is moved into position by a fluid pressure actuator 75 under the control of a programming device which sequentially produces electrical signals to indicate the required positions of the transfer point. Bar 67 is slidable longitudinally in narrowing bar supports 25 carried on shaft 27 and is pivotable out of the way of narrowing bars 21, 23. Shaft 27 is rotatable in the ends of pivoted carrier arms 29 and moves narrowing point bars 21, 23 and point 19 up and down. The movement is controlled by cams 47, 49 on axially movable shaft 45 which are respectively circular to hold point 19 out of operation and contoured to move point 19 up and down. A further cam 51 on shaft 45 operates a lever to actuate a micro-switch 63 possibly only when follower 43 engages cam 49 to cause a pulse to be delivered to lead 65 once per rotation provided that a further switch controlled by the automatic part of the machine is closed otherwise a pattern transfer would take place at every narrowing transfer. The pulse may be produced when point 19 is just out of reach of the stitch forming elements and then to initiate the actual transfer. Bar 67 is moved longitudinally by the piston rod 73 of a double acting pneumatic or hydraulic arrangement 75 through a link 71 such that bar 67 can swing when bar 27 is rotated. Hydraulic arrangement 75 is controlled by servo-valve 81 connected to pump 91 controlled by signals from control cabinet 85 which also controls a position-transmitter 95 on rod 73. The programme control comprises a step-by-step switching mechanism and a cross-bar distributor whose bars are connected in series with different resistances by a resistance decade (105), Fig. 3 (not shown). Mechanism (103) has a contact connected to the output of a differential amplifier (109) and at the start is connected step-wise to the bars of the distributor, Fig. 3 (not shown). Microswitch 63 may supply the step pulses to the switch mechanism. If switch 63 always produces a pulse when a transfer cycle is terminated and needle 19 is at its highest point the step by step switch is moved one step and the next positioning can begin. The other input of amplifier (109) is connected to the output of position transmitter 95 which transmits a voltage signal analogous to the position of the transfer needle and which is compared by amplifier (109) with the signal from distributor (107) through the switching mechanism. If the voltage signal indicating the actual position of the point and the voltage associated with the resistance indicating the desired position are different. The amplified difference is applied to servo valve 81 to vary the pressure at one side of the piston so as to alter the position of the needle 19 until the voltage difference disappears. Two or more points 19 may be provided on bar 67 if the same design is to be made in different positions.

Title: Improvements in and relating to electric telemotor control apparatus particularly applicable to automatic steering
IPC: G05D1/02
Filed: 1940-03-13
Abstract: 576,116. Automatic control systems for ships &c. CHANCE. E. M. March 13, 1940, No. 4725. Convention date, March 13, 1939. [Class 38 (iv)] Steering &c.-In apparatus for the control of a variable condition wherein control is initiated by the relative movement between two elements and one of them is operated by follow-up means responsive to the relative movement to restore the quiescent condition, the follow-up movement is varied by additional means responsive to the said relative movement which vary the operation of a differential drive associated with the follow-up system. Thus telemotor error in a steering system may be eliminated or initial rudder may be provided. Fig. 1 shows a system in which photo-electric cells L, R and a beam from a light source 2 constitute the relatively movable elements. A steering motor 9 is operated selectively in opposite directions through a reversing relay 6 according as the light beam reflected from a mirror on the compass card falls on cell L or R and a selsyn transmission 22, 23, 24 applies follow-up movements to the cell mounting 3 which surrounds the compass. The relay 6 also controls a reversible pilot motor 10 operating the selsyn transmission 23, 24 to apply additional movement in either of two opposite senses to the cell mounting dependent in extent upon the setting of limit switches 19, 20 in its circuits and in speed upon the adjustment of a series resistance 30. The additional follow-up may be effective only when the direction of yaw changes. The element 23 is an electrical differential device. The selsyn transmissions may be replaced by mechanical transmissions from the motors 9, 10 combined in a mechanical differential gear. One follow-up movement may .be applied to a main plate and the other to a plate carrying the cells and movable on the main plate. Specification 461,545 is referred to.

Title: Improvements relating to the manufacture of wired glass
IPC: C03B13/12
Filed: 1932-02-19
Abstract: 392,684. Glass manufacture. CHANCE BROS. & CO., Ltd., Glass Works, West Smethwick, and FORSTER, A. L., Glasgow Glass Works, Firhill, Glasgow. Feb. 19, 1932, No. 4963. [Class 56.] Relates to the manufacture of wired glass in which some of the reinforcing wires are disposed longitudinally of the sheet and others transversely, and consists in weaving the transverse wires in position simultaneously with the formation of the glass sheet. The longitudinal wires a, Fig. 1, are drawn horizontally from coils carried by a suitable tensioning frame, and after passing over a guide roller b, they pass between guide rollers c and are embedded in the molten glass as it passes between sheetforming rollers e. The wires pass through eyelets il formed in rods or wires i carried by two frames f, alternate wires a being passed through the eyelets of a different frame. The frames are connected to one another by chains g which pass around sprockets h, and they are reciprocated in opposite directions by the oscillation of a shaft t in order to separate alternate wires a, as shown. The wires a also pass through slots in a hollow horizontal member k, Figs. 1 and 2, arranged adjacent to the front frame f, and a tubular shuttle l slides through the member k. An electromagnet o, or an air cylinder, reciprocates the shuttle in synchronism with the movement of the frames. The shuttle is provided with any suitable means for gripping a weft or transverse wire p, and another gripper q, arranged at the side of the machine, is operated by the shaft t. In use, a length of wire p is fed by any suitable means into the shuttle l and is carried by it through the member k and between the wires a. At the end of the movement, the forward end of the wire is engaged by the gripper q, and the shuttle is withdrawn from the member k. The position of the frames f is then reversed, and the wire p is gripped between the wires a. Since the wires a are continually moving forwards, the member k may be mounted on links r, and be reciprocated in an horizontal direction by a lever s oscillated by the shaft t. The gripper q may also be mounted on one end of the member k.

Abstract: 1,207,221. Pinch seals in vitreous envelopes. GENERAL ELECTRIC and ENGLISH ELECTRIC COMPANIES Ltd. 28 Jan., 1969 [31 Jan., 1968], No. 5008/68. Heading C1M. A molybdenum foil pinch seal is made by joining one end of a strip of Mo foil to a conductor (the outer conductor), cleaning the surfaces of at least the mutually adjacent end portions of foil and conductor to remove any oxide film, forming a coating of an aluminoboro-silicate glass on the cleaned surfaces, the glass having a coefficient of thermal expansion closely matching that of the vitreous material which is to form the pinch, and heating to form a glaze, simultaneously or subsequently pinching a tube of fused SiO 2  or high SiO 2 - content glass (i.e. at least 90 wt. per cent of SiO 2 ) over the foil/conductor assembly at an elevated temperature (e.g. 2000‹ C.) so that the glazed portions are embedded in the pinch. The other end of the foil may be connected to an inner conductor, either before or after glazing the foil. The inner and outer conductors may be of Mo or W. Suitable glasses for the glaze and for the vitreous pinch material are given. The glass may be applied by applying glass powder of particle size not more than 10 microns to the foil and conductor, and heating at, preferably, above 1200‹ C. to fuse the glass. Preferably a non-oxidizing, e.g. hydrogen, atmosphere is used. The powder is preferably applied in a suspension in a hydroxylcontaining liquid, e.g. H 2 O, MeOH, at pH about 2 so as to form a coating not thicker than 1/1000 of an inch. The pinch seals formed may be formed in producing an incandescent lamp or an electric discharge tube, for example. The Mo foil and conductor may be cleaned by electrolysis in an alkaline solution (e.g. 30% w/v NaOH solution) followed by washing in distilled water.
