Title: Dial drive for knitting machines
IPC: D04B9/06
Filed: 1964-05-06
Abstract: 994,299. Knitting-machines. SINGER CO. May 6,1964 [May 6, 1963],No. 18921/64. Heading D1C. The dial of a cylinder-and-dial machine is driven from the cylinder by means of two rollers 56, 58 one 56 of which is secured to the needle cylinder driving gear ring 13 and the other 58 of which is secured to the annular dial driving support 33. The drive to the dial is imparted from the cylinder by the roller 56 bearing against the roller 58 with the fabric issuing from the needles passing between the two rollers so that the driving force is transmitted through the fabric. Simultaneously one of the rollers 56 is rotated by a gear 116 driven from the fabric take-up mechanism of the machine so that the roller 56 assists the passage of the fabric between the rollers 56, 58 at a rate equivalent to the rate of take-up of the fabric by the take-up roller. Alternatively the one roller may be totated through a worm and gear drive, the worm of which is normally held stationary as the dial rotates but which periodically is released to enable the roller to adjust itself to the rate of take-up of the fabric. The drive to the machine is transmitted through a clutch from an electric motor.

Title: Improvements in circular seamless hose knitting machines
IPC: D04B9/00
Filed: 1959-06-03
Abstract: 910,654. Knitting-machines. BEASLEY, E. G., and WESSON, E. June 1, 1960 [June 3, 1959], No. 18963/59. Class 74 (2). In a circular seamless hose machine producing heel and toe pockets by reciprocatory knitting on a substantially semi-circular group of needles whilst the instep group are inactive, regularly spaced and intervening needles throughout each group have butts of respectively different lengths, the butts of both lengths in one group being all shorter than any of those in the other group, and cams are provided which act on the butts to raise the spaced needles to clearing height whilst the intervening needles are raised to tuck height only. Micro-mesh fabric can thus be produced. Instep needles have alternately long butts LB and medium butts MB and heel and toe needles have alternately short butts SB and extra short butts XSB. The selecting cams immediately follow a stitch cam ST which all needles leave at tuck height TH. In Fig. 2, a movable cam A depresses the butts LB only, leaving the others at tuck height and a movable cam B subsequently raises the butts MB and SB to clearing height CH, leaving the butts XSB at tuck height to be joined by the butts LB which are raised by a fixed cam C. In Fig. 3, a movable cam D depresses from tuck height the butts LB, MB and SB, leaving the butts XSB to be raised to clearing height by a second movable cam E. A third movable cam F raises the depressed butts LB to join the butts XSB at clearing height and a fixed cam G raises the butts MB and SB to tuck height. In each arrangment, the needles brought to tuck height are caused to clear, or are left at that height, as determined by a micro-mesh selector.

Abstract: 247,142. S³d-Berliner Industrie Ges. Feb. 4, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Records, blanks for. - A plastic composition for making moulded sound records consists of, or comprises a condensation product formed by the action of an aldehyde or ketone on coal-tar creosote. Other phenols such as hydroquinone or resorcin may be incorporated, either by addition before the condensation reaction between the creosote and aldehyde &c. occurs, or afterwards; or separate condensation products of pure phenols with aldehydes may be prepared and added to the product obtained from creosote. Filling materials such as barium sulphate, soot, or fibre, may be added prior to or during the chemical action. Creosote contained in benzine obtained by low-temperature distillation of coal, or in benzine obtained from lignite tar or lignite oils, is stated to be suitable, for carrying out the invention. The composition obtained remains plastic for a certain time, during which it may receive sound-record impressions, but eventually becomes hard and infusible. When first formed it may be cast into blanks, or, whilst still liquid or doughy, may be squirted or spread on cardboard &c. sheets.

Title: Improvements in or relating to control devices for fluid pressure brakes of trains of motor lorries
IPC: B60T15/04
Filed: 1938-06-30
Abstract: 516,593. Fluid-pressure brakes. BOSCH GES. R. (formerly BOSCH AKT.-GES., R.). June 30, 1938, No. 19393. Convention date, June 30, 1937. [Class 103 (i)] In fluid-pressure brakes for tractors and trailer vehicles the control valve for the tractor brake is provided with a piston 35 or the like which is influenced by the pressure in the trailer brake pipe so that braking is only allowed in the tractor when the braking pressure on the trailer has attained a predetermined value. The tractor brake control valve 3 and the trailer brake control valve 2 are combined in a single casing and are both operated by a single balance lever 30 and brake pedal 32. Both valves comprise self-lapping arrangements involving valves 11, 48 and pistons 4, 37 and control the communication of the pipes 7, 42 leading to the respective brake cylinders with the compressed air supply 17 or the atmosphere through hollow piston rods 6, 38 and passages 55, 53. The trailer brake is spring applied and is normally charged with compressed air which is admitted also by a passage 52 to the piston 35 mounted on the rod 38 of the piston 37 of the tractor brake valve. This pressure acting on this piston 35 prevents operation of the tractor brake valve until this pressure has fallen a predetermined amount and the trailer brakes have been applied. A spring 22 provides resistance to the driver's foot. The lag in application of the tractors brakes is adjustable by means of perforations 31 on spring 62.

Title: Improvements in or relating to magnetic data storage devices
Inventor: BRADLEY EDWARD MICHAEL
Filed: 1959-06-08
Abstract: 942,674. Circuit arrangements for bi-stable magnetic elements. INTERNATIONAL COMPUTERS & TABULATORS Ltd. June 8, 1960 [June 8, 1959], No. 19492/59. Heading H3B. [Also in Division H1] A magnetic data storage device comprises a thin film of anisotropic magnetic material 1, together with a conductive strip 6 which when energized provides a field He making a small angle # with the easy direction of magnetization ED, and a further conductive strip 3 which when energized produces a field Hd perpendicular to He, the arrangement being such that simultaneous application of the two fields causes the remanent magnetization to change from direction 10 to direction 11. To switch the film from direction 11 to direction 10 only the field Hd is applied. The field Hd is greater than the hard axis saturation field. The field He is sufficiently small that by itself it will not switch the film. For successful operation the field He must be present during the decay time of field Hd, so that in operation it is suitable to make the He pulse straddle the Hd pulse. Read-out is effected through a strip 9 during the application of current to strip 3 alone. If the " zero " state is considered as that in which the remanent flux is in the direction 10, then a pulse on conductor 3 causes the flux to move to Hd after which it reverts to direction 10 so that the conductor 9 receives a positive pulse followed by a negative pulse. If the remanent state is in direction 11 corresponding to a setting " one," the application of the Hd pulse will take the flux past the hard direction of magnetization and upon its cessation the flux will go to direction 10. Thus conductor 9 receives two negative pulses. The read-out circuits are therefore made responsive at the leading edge of the read-out pulse. The thin film of magnetic material may extend over the whole of the surface 2, the area 1 being that portion which is affected by the conductors. Fig. 2 illustrates a matrix of such elements. Write in is effected by energizing a row conductor such as 3c together with appropriate column conductors such as 6a, 6d. Read out is effected by energizing conductor 3c, the amplifiers 14 being responsive only to negative pulses received from conductors 9, at the leading edge of the read-out pulse. The substrate upon which the film is deposited may be conductive and form a return path for the currents in the conductors. Specifications 880,383 and 942,549 are referred to.

Title: Improvements in friction speed changing devices
IPC: F16H15/46
Filed: 1920-07-08
Abstract: 147,569. Poignard, A. L. O. Jan. 24, 1914, [Convention date]. No Patent granted (Sealing fee not paid). Variable-speed friction gearing comprises a stepped cone R on a shaft M coacting with one, two, or more gears A, D movable together from step to step of the cone and sliding upon shafts T, Q which are connected by toothed gearing to a single shaft N. Either of the shafts M, N may drive the other. The shafts T, Q turn about pivots O, Fig. 2, at one end, and at the other are connected by links I, J to a collar S pressed to the left by a spring K. The spring K thus keeps the gears A, D thrust against the cone with force proportional to the driving-force. A lever U may compress the spring K to disconnect the drive. Means V, X are provided for reversed driving. In the application to a motor-vehicle, an additional proportional friction thrust may be obtained from the propelling thrust of the road wheels. Such thrust passes through a rod 8, Fig. 4, which acts on a lever 12, so that a minor part of it is passed through a link 13 and turns a shaft 11. A fork 15, Fig. 3, upon the shaft 11 thrusts the rear end of the spring K forwards, increasing its tension. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement with two shafts only such as T, Q connected separately to the two road wheels of a vehicle. thus dispensing with the differential. The differential action is allowed for by slipping of the friction gearing. Also, the friction gearing might be replaced by toothed gearing. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in separable sliding clasp fasteners
IPC: A44B19/04
Filed: 1952-08-05
Abstract: 775,172. Sliding-clasp fasteners. PLASCO, Ltd. Aug. 5, 1952 (Aug. 9, 1951], No. 19647/52. Class 44. Relates to a separable sliding clasp fastener of the type the scoops or fastening elements on opposed tapes interengage so as to prevent separation of the tapes in a plane containing the tapes and a plane normal thereto and is characterized in that centrally arranged coupling ridges on the coupling heads of the scoops make a pressure engagement with the bead of an opposed tape and coupling lugs on the mounting portions of the scoops overlie the ridges on the scoops on an opposed tape. In the embodiment of Figs. 1 and 2, scoops 16, 16<SP>1</SP> have mounting portions 18, 18<SP>1</SP> for securing the scoops to the beads 17 and 17<SP>1</SP> of stringer tapes 15 and 15<SP>1</SP> respectively. The scoops are identical in construction and thus referring only to a scoop 16, this has a coupling head 19 connected to the portion 18 by a reduced neck 20 which neck is also defined by grooved sides as at 23, Fig. 2. The head 19 is approximately barrel-shaped having flat reduced ends 25 and a blunt and rounded nose surface 26. Projecting centrally from the surface 26 is the ridge 27 which in plan view has contracted sides 28, Fig. 1. The mounting portion 18 is provided on each side of the bead 17 with upper and lower outwardly projecting lugs 30. When the tapes are coupled together projecting portions 22 of a head 19 interengage with V-shaped recesses, formed by the neck 20<SP>1</SP> of an opposing scoop 16<SP>1</SP> and prevent pull-apart separation of the tapes. At the same time the ridge 27 engages between lugs 30<SP>1</SP> of an opposing scoop and also presses into the opposing bead 17<SP>1</SP> whilst the lugs 30 engage an opposing ridge 271 which also presses into the bead 17. The interengagement of the ridges and lugs prevents transverse separation of the tapes, i.e. in a direction perpendicular to the plane through both tapes. The outer edge of the central ridge may be rounded instead of straight as shown in Fig. 1, and the contracted sides 28 of the ridge may terminate short of the upper and lower edges of the nose. In a modification (Fig. 6, not shown) the coupling heads are off-set in relation to the mounting portions, the beads on one tape being of opposite "hand" to those on the other tape. In a further modification described with reference to Figs. 8 to 10 (not shown) tapered key members extend normally to the ridges on each side thereof, the key members engaging between the lugs on adjacent scoop mounting portions on the opposed tape.
