Title: Method of producing patterned felts, especially for hat bodies
IPC: D04H13/00
Filed: 1960-07-06
Abstract: 916,518. Making patterned felt hat bodies. BINDER, H. July, 6, 1960 [July 8, 1959], No. 23665/60. Class 63. [Also in Group VIII] Fur or fibres are first applied to a hat form by suction or winding before the felting operation, a pre-fabricated net-like or openwork structure is applied to the shape, a further layer of fur or fibres is then formed on the shape and the shape is then felted and, if required, planked, whereupon the felt layer covering the prefabricated structure is partially removed to render visible the prefabricated structure. In the example described, a bell-shaped net of fast dyed wool threads is applied to the shape of fur formed by suction and another layer of fur then applied. The shape is then felted and planked in acid planking and after drying the body produced is roughened by means of a rapidly-rotating disc coated with rough fish skin so that the body acquires a hairy surface in which the woollen threads are clearly distinguished. The prefabricated structure may comprise shrinkable or non-shrinkable material and instead of a net may comprise a thin perforated felt or metal filaments or wires.

Abstract: 1,179,714. Contacting gases with liquids. RHONE-POULENC S.A. 22 May, 1967 [25 May, 1966], No. 23689/67. Heading B1R. In a gas/liquid contact apparatus liquid is circulated from a cylindrical gas/liquid separator through a U-tube with limbs 18 and 11 and back into the separator, gas being introduced into the liquid at 20, the separator 14 having a gas outlet 15 and being connected to the U-tube by pipes 13 and 16 tangentially disposed to the separator. Liquid may be introduced at 23 and the limbs of the U-tube are surrounded by heat-exchange jackets. Pipes 13 and 16 are shown horizontal but may be inclined slightly (up to 15), both tubes sloping downwardly from the separator. The limbs 11 and 18 of the U-tube are shown vertical but they may diverge slightly in an upwards direction. A second U-tube with a pair of tangentially connected pipes may be associated with the separator. Gas may be recirculated, liquid withdrawn and the liquid may include a solid, e.g. a catalyst, in suspension. The liquid in this latter case may be treated in a decanting vessel, a separated slurry being returned to the U-tube.

Abstract: 969,191. Making wire; stretching at specified temperatures; altering physical structure. SOMERSET WIRE CO. Ltd. Sept. 13, 1960 [Sept. 26, 1959; Oct. 27, 1959], Nos. 23704/59 and 36295/59. Headings B3A, B3E and B3V. In apparatus for straightening wire ropes, strands &c. and increasing the proof stress or resistance to creep, the strands are continuously fed over a series of pulleys 10-15, Fig. 4, frictionally engaging the wire, each rotating at the same angular velocity but having progressively increasing diameters to progressively produce a predetermined strain, the so-strained wire being heated over a predetermined length to a temperature within the tempering range to produce a permanent elongation. In examples applied to high tensile steel wires having a carbon content Within the range 0.35 to 0.9% the tempering temperature is within the range 220- 500‹ C., and preferably within the range 250-380‹ C. With alloy steels the temperature may be as high as 600‹ C. The wires may be electrically heated along a loop 23 in the region of maximum strain and formed by the wire passing over a separately mounted remote pulley 14. Current is passed between the pulley 14 and the remaining block of pulleys 19 by brush contacts 32 or slip rings 35. The wire then passes through a cooler 36, Fig. 3, before leaving the loop 23 over pulleys 16-18 which have successively smaller diameters which reduce the tension in the wire before it passes to winding and reeling drums (not shown). The wire may be pulled directly from a stranding machine through the apparatus, solely by the winding and reeling drums or these may be coupled through chains or gears for driving the pulley system. Specifications 748,357 and 969,192 are referred to.

Title: Signaling device
IPC: B60Q1/38
Filed: 1955-08-19
Abstract: 780,549. Road-traffic signals on vehicles. HOLLINS, J. R. Aug. 19, 1955, No. 23946/55. Class 118 (2). The normal side and rear lights of a vehicle are utilized to provide a flashing warning during an emergency stoppage, and the stop lamps and head-lamps are disconnected to avoid their brighter illumination detracting from the flashing signals. A special "flare" switch FS is connected between the vehicle battery 10 and the normal lighting control switch HCS, and is wired as shown to head-lamps HL, side-lamps PL, stop-lamps SL, tail-lamps TL, and licenceplate-lamp LPL. A flasher unit FL is connected in parallel with the flare switch FS and has a pilot lamp FP. A brake pedal switch 20 normally controls stop-lamps SL. Switch HCS is shown in its off-position but when knob 17 is pulled to its first position the sliding contact member 18 connects side and tail-lamps via the flare switch FS to battery 10. When knob 17 is pulled further the tail and head-lamps are brought into circuit. Flare switch FS comprises a control handle 41 which slides contact members 43 and 44 such that in the normal position shown the high resistance flasher FL is shorted out and battery 10 is connected to the control switch HCS and brake pedal switch 20. When the handle 41 is pulled to its emergency position the short is removed from flasher FL which then supplies switch HCS intermittently and the circuits to the brake pedal switch 20 and head-lamps HL are broken. Thus with the flare switch in its emergency condition the sidelamps PL and rear-lamps TL and LPL only can be energized, and these will flash together. The pilot lamp FP also flashes to indicate this condition.

Abstract: 987,675. Pipe joints. W. C. N. HOPKINS. July 4, 1961, No. 24150/61. Heading F2G. [Also in Divisions B3 and F2] A method of forming a ball joint P which may be used between the sections of an exhaust pipe, Fig. 1 (not shown), comprises telescoping the ends of two-tube metal tubes and expanding the inner tube into the form of a ball 3 within the outer tube. In Fig. 7, both tube-ends are expanded simultaneously. A ridge 22 formed in the ball 3 at the end of the socket 4 is removed in a lathe by a roll, Fig. 8 (not shown). In another form, Fig. 15, the tubes are expanded separately, that forming the socket 53 being expanded first. The tube-shank 52 also is expanded until its inside diameter is equal to the original outside diameter, so that it can be fitted over and joined to another tube of the original outside diameter. A second length of tube is then expanded within the socket 53. As before, the ridge may be removed by rolling, Fig. 18 (not shown), and a knock may result at the end of the ball. Lubrication holes may be drilled in the socket (Fig. 16), and at least one of the bearing surfaces may be coated with molybdenum disulphide.

A multipole circuit-breaker with operating- mechanism generally similar to that disclosed in Specifications 684,390, 684,327 and 684,311 has a common trip-bar 12 carrying an adjustable catch 16 which engages a tripping-lever lever 17, pivoted at 19a. The bar 12 is pivoted at 14, coaxially with the dolly 5, and is biased by an adjustable compression-spring 22 so that the annular surface 16b of the catch 16 engages the edge of a hole 17a in the lever 17 which is biased against the catch by a spring 19, the nose 16a of the catch projecting through the hole 17a. When the bar 12 is moved clockwise (Figs. 6 and 7) by the armature 13 of an overload coil 1 or by the operating-plate 11 of the earthleakage coil 2, the surface 16b disengages the edge of the hole 17a and the spring 19 moves the lever clockwise so that its other end engages the member 18 to break the toggle 6, 6a and allow the contacts 3, 7 to separate. During the opening movement a pin 20 on the moving contact-arm engages the lever 17 to restore it to the Fig. 6 position and the spring 22 resets the catch 16.

The arms 7 are pivoted at 8 to brackets 9 adjustably clamped to members 12 on the machine frame. Actuating links 21 pivoted at 19 to the arms 7 are adjustably secured by frictional spring-loaded clamping devices 25 and brackets 35 to the pillars 63 carrying the reciprocating head 37. Rollers 15 on the lowermost rod 3 coact with curved guide surfaces 17 to move the guard towards the operator as it is lowered. Corresponding markings 55, 57 are provided to enable correct positioning of the clamps 25 and brackets 9 when adjusting for different stacks of workpieces. If the guard is obstructed and its downward movement arrested, it may pivot about the pins 6, or the links 21 may slip in the clamps 25. The linkage provides accelerated downward movement of the guard with respect to the head as the latter approaches the work and after the arms 7 have passed through a horizontal position.
