Abstract: 945,002. Folding edges of non-metallic sheet material. AUTOMATIC BRAIDING CO. (NOTTINGHAM) Ltd. April 19, 1960 [April 27, 1959], No. 14211/59. Heading B5K. [Also' in Divisions B8 and D1] In an apparatus for folding and sticking a covering strip C, Fig. 8, around one or more tensioned elastic cores A, B (see Division B8), the folding of the covering strip about the core or cores is effected principally by their travel around a roller 32, Fig. 5, by ensuring that when the machine is initially set up the margins of the covering strip C are already folded over the core or cores A, B at the draw-off side of the roller 32. When the machine is then set in motion this folding relationship will be maintained on the ribbons and the cover strip pass around the roller 32. To ensure accuracy of folding, the covering strip C is subjected to a preliminary folding by side walls 33, 34, Fig. 7, and by bevel-edged light-pressure finger elements 35, 36. A releasable catch device 38, Fig. 5, releasably holds the finger elements 35, 36 in position. The catch device 38 comprises a trip arm 38a biased by a spring 38b to urge the fingers 35, 36 against the work, and a manually displaceable detent arm 38c. Thus, the finger elements 35, 36 can be lifted and held clear by the detent for setting up the work, and can be re-set upon manual displacement of the detent. Specification 918,096 is referred to.

Patent GB-143897-A (GB)
Title: Improvements in and connected with the feeding of fuel to the carburettors of internal combustion engines
IPC: F02B1/00
Filed: 1920-05-27
Abstract: 143,897. Daimler-Motoren-Ges. Sept. 17, 1917, [Convention date]. Spray carburettors.-In a fuel-supply system to a carburettor, particularly applicable for use on aeroplane engines in which the air is temporarily supplied under increased pressure by a compressor or the like, the fuel is normally fed by the usual pressure in the fuel tank, but, at such times as the air-compressor is in operation, is fed under increased pressure, the increase in pressure being applied after the fuel has left the fuel tank. As shown in Fig. 1, the fuel-supply pipe f leading from the pressure-fuel tank d is fitted with a pump g delivering into a pressure-equalizing tank h connected by a pipe i to the carburettor k. The tank h is connected by a return valve m and a pipe n to the pipe f on the suction side of the pump. When air is supplied under normal pressure through the pipe c, the pump g is not in action, its valves and springs being so proportioned that the fuel is forced through the pump by the pressure in the fuel tank. If, however, the air is supplied under pressure, for example by a compressor b, the pump g is put into action to increase the pressure of the fuel supply, so that it is higher than the air pressure in the pipe c. The pump g may be replaced by a gear-wheel pump, the tank h, valve m, and pipe n being dispensed with. The pump is designed so that, when not in action, fuel may pass therethrough under the pressure in the fuel tank, and is arranged to allow a certain amount of slip, so that the pressure in the fuel pipe cannot exceed a predetermined amount.

Abstract: 960,453. Drilling; machine-tool details. CAVITRON ULTRASONICS Inc. April 24, 1961, No. 14709/61. Headings B3B and B3C. [Also in Divisions A5, F2 and H4] A high-speed drill 39 or like worktool is frictionally driven from a driving member 4, the driving surface of which moves in a circular or elliptic path and is maintained in tangential driving contact with the drill for a limited portion of each cycle. As shown the driving surface is a circular or elliptic hole 37 through which the drill passes and the orbital motion of its centre is generated by the member 4 which due to its asymmetric shape, converts longitudinal vibrations, supplied by a magnetostrictive vibrator 2 into orbital motion. The outer plastic case 17 of the vibrator 2 forms a handpiece. The drill may, as shown, have a cutting tip 40 of substantially the same diameter as its stem 38 which does not exceed three millimeters and may have a diameter of less than one millimeter. In Fig. 5, the tool is shaped to cut out a small centrally apertured disc, in Fig. 6 the tool has a conical tip, whilst in Fig. 7 the cutting tip is a fine wire for drilling extremely small holes of a few microns in diameter. The driving member 4, Fig. 3, produces a circular path at the driving surface, whilst different shaped driving members produce an elliptic path or a combined circular path and vibration along the axis of the drill. In Fig. 14 a number of driving surfaces are provided on the driving members to drive a cluster of drills. The driving surface is made of hard wear resistant material such as diamond, sapphire, tungsten carbide or titanium carbide.

Abstract: 313,077. Electrical Research Products, Inc., (Assignees of Gilbert, J. J.). June 6, 1928, [Convention date]. Cable circuits modified to improve transmission.-In order to reduce impedance irregularities of a submarine cable of great overall attenuation, for use in duplex telegraphy, the end sections are formed with loading of increased thickness and reduced permeability; the product of the quantity of the loading per unit length and the effective permeability being maintained approximately the same for all sections. The effective thickness of the loading may be varied by varying the number of layers of tape, or by using a single layer of tape of different thickness on different sections, or the lay of a uniform tape may be varied. In order to maintain the transmission efficiency constant throughout the cable, the resistivity of the loading may be regulated with respect to the number of layers on each section. Fig. 5 shows a long cable arranged for duplex telegraphy in which the thickness of the loading is progressively decreased in steps N1 - - N4, from the ends to the centre of the cable, the permeability being progressively iucreased from the ends to the centre. In a modified construction applicable to continuously lump loaded cables, the end sections are loaded uniformly with low permeability material, and the central section loaded on uniformly separated sections only with high permeability material.
