Title: Pattern selecting mechanism in a knitting machine
IPC: D04B15/78
Filed: 1968-05-28
Abstract: 1,214,934. Knitting-machines. NORTH AMERICAN ROCKWELL CORP. 28 May, 1968 [23 June, 1967], No. 25437/68. Heading D1C. In a knitting-machine jacquard device the pattern strip 24 comprises spaced pairs of rows of perforations 27 and a series of levers alternate ones 30 of which feel one row of each pair and intervening ones 31 feel the other rows. The rows and corresponding grooves in the drum 21 are helical. Levers engaging a perforation and pushed forward as the drum rotates are depressed by cam 39 and thereby raise the jacks via pivoted levers 41. Such levers are returned to their initial positions by springs 34, 35 when they lose contact with the perforations.

Title: Improvements in or relating to apparatus for filling containers with liquid
IPC: B67C3/26
Filed: 1946-08-26
Abstract: 626,967. Bottling-machines. BINGHAM, D. W. Aug. 26, 1946, No. 25502. [Class 125(ii)] Apparatus for filling bottles and other like containers with liquid by suction comprises an endless container conveyer 3 having a straight line forward path, a second endless conveyer 21 carrying a series of filling heads 11 and having a straight line portion mounted above and parallel to conveyer 3, a distributer valve 8 connected by pipe 7 to a liquid storage tank 6, by pipe 16 to a vacuum pump and by pipes 9 to each of the filling heads 11, and means for automatically lowering and raising each head 11 relative to conveyer 3 to engage and disengage a container neck as the two conveyers move forward parallelly and at the same speed. Conveyer 21 passes around driving sprockets 22 and is held against vertical or lateral displacement by engagement with trackways 24. The filling heads 11 are carried on slide members 31 which are raised and lowered relative to conveyer 21 by engagement of rollers 32 with fixed ramps 33. The filling and suction pipes 9 leading to each filling head are connected to filling and suction ports in a rotary member 67 of valve 8, and during engagement of the head 11 with a container these ports register with a pair of corresponding ports in a fixed valve member 66. Each filling head 11 comprises a bell-mouthed centering member 52 (Fig. 7) which is raised against spring pressure, when engaged by a container neck, to lift a filling pipe 41 from its seating 51 to allow liquid to enter the container via passages 38, 39 and 47, air being withdrawn through passage 46. Excess liquid delivered to the container is sucked up through the vacuum line and trapped in a separator 14 interposed between valve 8 and the vacuum pump. The container conveyer 3 and the filling heads 11 may be relatively adjustable to accommodate different sized containers.

Abstract: 406,760. Control of motors. WOOD, W., and WADSWORTH & SONS, Ltd., W., High Street, Bolton. Sept. 14, 1932, No. 25596. [Class 38 (iii).] Travelling to predetermined limits.-The brush rockers a, b, of a lift or elevator motor c, are connected by a chain or rope d passing over a pulley or like balancing member e, and round a drum f driven by an auxiliary motor h through a friction clutch ; so that rotation of the motor h causes the brush rockers to move equal amounts in opposite directions. Reversing contactors x, x', for the main motor are under the control of a car switch u, limit switches v, and a switch n which ensures that the brush rockers are in their slow speed position before the main motor is started. The auxiliary motor h is under the control of a contactor k and limit switches p, q. The contactor k closes forward contacts, corresponding to acceleration of the main motor, when its coil is energized by operation of the car switch u, and reverse contacts under the action of gravity when the coil is de-energized. Switches r, interlocked with car switches s, are provided whereby, if the brush rockers are not returned to the slow speed position when the car approaches a floor level, the supply to the main motor is cut off at such points that the car is levelled properly. The drum f may vary the speed of the brush rockers with constant auxiliary motor speed.

Title: Improved course-recording apparatus
IPC: G01C22/00
Filed: 1920-09-11
Abstract: 172,147. Hamilton, W. Sept. 11, 1920. Course - recording apparatus. - Consists of an apparatus for use on vehicles, in which a cam &c. is rotated by a differential gear device to produce changes of velocity in index-moving elements whenever the course of the vehicle is changed. In the construction shown, the spindles 1, 2 geared to the front wheels of the vehicle, and rotating in opposite directions are respectively geared to the sun-pinion 5 and the internally - toothed annulus 7 of a sun-andplanet gear. The planet pinions 8 are journaled in a spider 9 which is fast to a sleeve 10 mounted on a fixed spindle 11 and carrying a cam 12. The gear ratios are such that when the road wheels rotate at the same speed the sleeve 10 is stationary. Mounted in bearings 24 are two shafts 22 at right-angles to each other abutting at their outer ends against the cam 12. These shafts pass through slotted and axially-fixed sleeves 20, 21 carrying wormwheels 18, 19 gearing with worms on the spindles 1, 2 so that the sleeves are rotated at speeds proportional to those of the road wheels. Each shaft 22 carries a pin 27, Fig. 5, passing through the slot in the sleeve, and the latter carries a second pin 28, the two pins being secured to the ends of a resilient ring 29. Each of these rings thus acts as a rotary helix, the pitch of which is altered when the corresponding shaft 22 is displaced by the rotation of the cam 12. The index elements comprise wires 13, 14 at right-angles to each other mounted over a map &c. 34 and secured to endless bands 15 passing round driving-pulleys 30, 31 and idle-pulleys 16. The rings 29 press against the bands and drive them at speeds depending on the pitches of the rings and thus varying when the course of the vehicle changes. The driving- pulleys are mounted on spindles 32 which can be withdrawn by hand to facilitate initial setting of the wires. The position of the vehicle on the map is denoted by the point of intersection of the wires. A modification described in the Provisional Specification comprises three friction discs rotated at speeds proportional to that of the vehicle and each driving a differential mechanism. One of these mechanisms is connected to the steering gear so as to be displaced across its driving disc when the course is altered, and its intermediate member carries a cam which is connected by levers to the remaining mechanisms, the intermediate members of which are connected to the index-moving elements.

The member 8 is U-shaped in cross-section and the bar C is housed within the channel of the longitudinal member of the closure and a spring 11 forces hooks 9<d> on bar C into engagement with the posts 3; the bar C is retracted to open the box by a key which is inserted in a barrel 16 and is rotated to engage a, shoulder on the bar. The coin-slot is located in one of the end members of the closure 8 and is provided with guards 17<d>; bills may be introduced through an opening 18. The plates 2 are connected by studs 7 which prevent unauthorized manipulation of the bar C through the openings 17 or 18. The edges 4 of the plates 2 may be struck away from the side walls of the casing 1 to serve as guides for the flanges of the closure 8. The sides of the casing may be padded at 6 and covered with cloth, leather or paper 5.

Patent GB-1010898-A (GB)
Title: Method of treating a porous, high silica content glass
IPC: C03C23/00
Filed: 1964-06-29
Abstract: Water is eliminated from porous 96% silica glass articles by displacing OH radicals with chlorine ions by exposing the glass to a chlorine containing atmosphere at a temperature of from 600 DEG  C. to 1000 DEG  C. thus appreciably changing the beta value of the glass. The active component of the treating atmosphere may be chlorine gas, hydrogen chloride gas, ammonium chloride or its dissociation products, or the dissociated products of carbon tetrachloride, silicon tetrachloride or tri-chloroethylene entrained in nitrogen.  Various examples are given showing the effects upon the resultant beta value of the time of exposure to various strengths of chlorine atmospheres at different temperatures between 600 DEG  C. and 1000 DEG  C. for glasses of different thicknesses. The final consolidating treatment is preferably carried out in an inert atmosphere, e.g. nitrogen, or in vacuo, but where a very low beta value is not required the use of dry air with rapid firing may be suitable.  The final treatment may also be carried out in the chlorine atmosphere. Specification 442,526 is referred to.
