Abstract: 1,186,968. Ropes and apparatus for making ropes. BERGEN SLYNGEEFABRIKK A.S. 4 March, 1968, No. 10366/68. Heading D1T. [Also in Division A1] A floatable cord is made by feeding a core 20 of continuous filament threads into a braided sleeve 14 of filamentary material, and arranging particles of expandable plastic material 18 between the core and the sheath. The particles may be of heat-expandable material, such as polystyrene, so that on expanding said particles the cord becomes floatable. The material 18 may be continuous or, as illustrated in Fig. 3, it may be in spaced apart portions by using means such as a cam 34 to oscillate a nose 37 on a spring arm 38, the movement of the nose 37 serving to open and close a discharge opening 33 for the material 18. The opening 33 thus dispenses spaced apart doses of the material 18 into the sleeve. By means of additional dispensers there may be disposed between said spaced apart doses of material 18 doses of expanded foam plastics particles, unexpanded plastic and/or other filler material. The filled sleeve passes through a vessel 21 of hygroscopic fluid mixed with water, thence to a drawing arrangement 24 and finally to a container 14a having a perforated wall and base. The collected cord is then passed to a heated fluid bath (not shown) having a temperature below the fusion temperature of the expandible material 18 and maintained there until the material 18 has expanded to the desired granular size and without the particles thereby being fused together to any substantial degree. Fig. 4 shows how the cord expands when the material 18 is inserted into the braided sleeve in spaced apart doses. The core threads 20 are preferably fuzzy so that they can initially be charged with static electricity to cause the particles of the material 18 to attach themselves to one another and to the core 20.

Abstract: 882,045. Disc brakes. DUNLOP RUBBER CO. Ltd. March 14, 1958 [April 1, 1957], No. 10511/57. Addition to 738,545. Class 103 (1). In a spot-type disc brake in which each limb of a non-rotatable housing is provided with a fluid pressure mechanism operable to force an associated friction pad into frictional engagement with the disc, means associated with each limb prevents movement of the friction pads in either tangential direction relative to the disc when the brake is applied, and means being detachable from each limb permits removal and insertion of the friction pads in one tangential direction. In the spot-type disc brake illustrated, the friction pads 13 are bonded to backing plates 32 provided with internal flanges 31 which engage in grooves 30 provided in flared portions 25 of fluid pressure operated pistons 18, the pads being readily removable for replacement purposes by removal of yoke members 42 bolted to caliper housing 1 and sliding the friction pads and backing plates out in a tangential direction with respect to the brake disc 4. Flared portions 25 on each piston 18 also prevent abutment of the backing plates 32 against the disc when the friction pads are worn since the flared portions 25 abut rims 37 of the caliper housing 1 and yoke member 42. Perforations 36 in the backing plates 32 reduce heat transfer to the piston on brake application. The Provisional Specification also describes an automatic adjustment device. Specification 688,382 is referred to.

Abstract: 347,846. Chucks. HERBERT, SIR A., Dunley Manor, near Whitchurch, Hampshire, and HARRISON, H. T., 44, Melville Road, Coventry. April 4, 1930, No. 10711. Class 83 (iii).] In a self-holding chuck wherein the jaws are actuated by a rotatable cam, the cam is rotated through gearing by a rod passing axially through the chuck spindle. The radial jaws 3 are adjustably secured to slides 4 which carry slipper-blocks, rollers, &c., engaging the cam-plate 7, which may comprise a group of cams, a spiral or a scroll and which has a toothed segment meshing with a hypoid, skew or other bevel gear 12 or a spherical or ovoid worm on a tangential shaft 11. Alternatively, face-spiral gearing may be used. The shaft carries a pinion 14 which may be rotated for moving the jaws by means of rack teeth on a hollow member 16 connected to a plunger passing through the hollow spindle and moved axially by a pneumatic or hydraulic piston, screw gearing or a solenoid. The thrust of the rack and pinion is balanced by a plain roller 17 engaging the member 16 on the side opposite to the pinion, the roller and its shaft 19 being similar to the pinion and shaft &c. with the exception of the gear teeth. The shafts 11, 19 are carried in ball bearings 20 mounted in bores 21 in the chuck body 2 and are kept in position by blocks 22 shaped to the curvature of the body and secured by screws. Cuttings &c. are excluded from the interior of the chuck bv means of a sleeve 25 inserted in the member 16, the inner end being closed by a screw plug and the outer end being attached to a plate 27 secured to the body by screws. The gearing is so arranged that the actuating plunger may be operated by a small force through a large distance, the cam having a non-severable action on the jaws so that the fluid pressure &c. may be used for actuating the jaws only, and not for maintaining the grip.

Title: Code translator
IPC: B07C3/00
Filed: 1972-03-09
Abstract: 1360523 Code conversions INTERNATIONAL STANDARD ELECTRIC CORP 9 March 1972 [9 March 1971] 10935/72 Heading G4H A code translator uses a decoder matrix and a coder matrix, both of magnetic cores, with code wires selectively threaded through both, and reduces the number of cores required by using (further) selection means controlling the code wires. Five 5-bit characters are read from a letter in a letter sorter. Four bits of each character are decoded by logic to 1-out-of-16 form to pulse positively a selected one of 16 magnetic cores (via a drive winding) in a corresponding one of 5 rows in a decoder matrix. A number of coder wires each thread one core in each row and also four compensation cores, the compensation cores being all pulsed negatively via drive windings, so that only one of the coder wires receives a net positive current. Each coder wire is connected via diodes to up to 32 branch wires, each threading a selection of 5 out of the 12 cores in each of 8 rows of cores in a coder matrix. The other ends of the branch wires are each connected to one of 32 selection transistors, one of which is rendered conducting by logic decoding the remaining 5 bits of the input (one bit from each character) to 1-out-of-32 form. Outputs on read windings of the cores in any row of the coder matrix can be taken. Alternatively, a 6 character input can be converted by using 5 of the characters to select a core in respective rows of the decoder matrix, and using the 6th character to select one of 16 transistors. Other modifications of the first embodiment are to have a separate wire in the decoder matrix for each "branch wire" in the coder matrix, and to select a wire using 1 out of 4 transistors plus 1 out of 8 transistors, instead of 1 out of 32 transistors.

Abstract: 1,142,407. Cathode ray tubes. COMPAGNIE FRANCAISE DE TELEVISION. 8 March, 1967 [10 March, 1966; 20 Jan., 1967; 13 Feb., 1967], No. 11007/67. Heading H1D. In a glass cathode-ray tube formed of two envelope portions hermetically sealed to one another, a grid of stretched metal wires constituting a post-deflection acceleration or focusing grid is mounted in the tube by having the ends of the wires embedded in the seal between the two portions and extending to the outer surface of the envelope, the outer surface of the seal being coated with a layer of electrically conductive material and a superimposed layer of material of a nature which ensures that the seal is airtight. A focusing and post-deflection-acceleration grid in a colour television tube is composed of stretched wires 4 extending through the seal 6 (but only partly shown as such) of ceramized glass cement, the ends of the wires being cut-off flush with the outer surface 4a, and coated first with a layer 7, formed of colloidal silver and ceramizable glass and having an extension 7a to a contact terminal 8 provided on the faceplate portion of the tube, and thereafter with an hermetically sealing layer of ceramizable glass 9, which may itself be covered by a ribbon 10 of glass fibres. The grid wires may be of stainless steel, whereby their tension increases, due to differential contraction with respect to the envelope glass, upon cooling from the sealing temperature. A grid structure mounted as described above increases the implosion resistance of the tube, and permits the use of a plane of reduced thickness e.g. a plane rectangular faceplate having a thickness 1/25th the length of the diagonal, or a plane circular faceplate having a thickness 1/30th the diameter. The three-gun colour tube of Fig. 4, has a focusing grid 13 connected to a further electrode 112, and a plane faceplate 14 with a peripheral groove 110, whereby the luminescent strips 16 on the faceplate may be produced by a contact printing process; the screen is coated with superposed layers of aluminium 17 and porous graphite 18.

Abstract: 1,176,605. Making tubes. STANDARD TELEPHONES & CABLES Ltd. 7 March, 1968, No. 11049/68. Addition to 1,128,529. Heading F2P. [Also in Division B8] In order to reduce friction between layers during the convolute wrapping of a strip, e.g. of paper, into tubular form having a spiral cross-section and an outer layer which overlaps an inner layer by at least 360 degrees, a skeleton die is formed from a number of elements which are well-spaced along an axis 9 and which each have an aperture 10 through which the axis 9 passes, the apertures in a first group 2-5 of adjacent elements being profiled so that they lie on the boundary of a first imaginary tapering passageway 9, and a slot 14 in communication with the passageway along one side thereof which slots are longitudinally aligned, and the apertures in a second group 6-8 of adjacent elements being profiled so that they lie on the boundary of a second imaginary tapering passageway 12 whose larger end is adjacent the smaller end of the first passageway. The arrangement is such that when a strip of material is drawn through the elements along the axis 9, the first group of elements 2-5 wrap the inner layer of the tubular member leaving at least half the width of the strip outside the first passageway and projecting into the slot, and the second group, 6-8, wraps the remaining uniformed width of the strip around the inner layer to form the outer layer, tension being maintained in the strip as it passes into the apparatus so that the portions of the strip projecting into the slots 14 are prevented from entering the first passageway. The elements 2-8 correspond with the equivalent crosssections of the solid die described in the parent Specification. In order to reduce friction a maximum amount of material may be removed from the plate portion which would otherwise contact the strip, e.g. plate 5 ; alternatively, the plates 2-8 may be replaced by thick wire bent to the shapes of the apertures and secured to the base 1. The plates 2-8 are advantageously made of tungsten carbide. To insulate a wire conductor the inside of the edge which is to become the end of the outer layer is coated with an adhesive and the wire is drawn through the apparatus at the same time as the strip, radial pressure being applied to the overlapping edge as the insulated wire is wound upon a capstan. In order to locate the wire centrally within the insulation the portion of the width of the strip which forms the inner layer may be longitudinally corrugated, Fig. 4 (not shown).
