Abstract: 702,757. Welding and dividing by fusion. FUSARC, Ltd., and STRETTON, H. J. Jan. 10, 1952 [Jan. 24, 1951], No. 1805/51. Class 83 (4) A portable machine for fusion welding or flame cutting comprises a hollow body manipulated by the user, an electrode feed or flame nozzle on the body and a castor for supporting the body on the work rotated by a variable speed mechanism contained in the body. In an embodiment of a welding machine a hollow bracket c inclined at about 60 degrees to the horizontal is mounted on one side of a hollow body a and carries at its lower end a swivelling arm d supporting a rubber tyred castor e. Feed rollers i, j, contacts h, and guide g for an electrode f are fixed to the same side of the body a while handles b extend towards the other side. To rotate the castor e an electric motor m in the body a drives a friction disc n which contacts a friction disc o mounted on a splined spindle p and adjustable thereon to vary its speed by a knob t turning a screw s on which a sleeve j carrying the disc o is mounted. The spindle p through helically toothed wheels u, v, shaft w and wheels x, y, rotates a shaft 2 rotatably mounted in a sleeve 3 attached to the arm d and mounted in bearings 4 in the bracket c. The shaft 2 drives the castor e through wheels 5, 6, 8, 9, and shaft 7. A toothed wheel 14 on the sleeve 3 engaging a spring loaded rack 12 serves to return the arm d after lateral movement. A motor 15 drives feed roller i through a similar friction disc drive. A blower may direct air through a tube 32 to deflect welding fumes. One motor or a flexible drive shaft or shafts may replace motors m, 15, and may drive one or two friction discs. An oxyacetylene nozzle may be fixed to the body a in place of the electrode feed device.

Filed: 1958-01-20
Abstract: 867,536. Lifeboat winches. SCHAT DAVITS Ltd. Jan. 20, 1958, No. 1872/58. Class 78 (5). A winch drum 5 carrying the two lifeboat rope falls 7, 8 is driven alternatively by motor 31 or by handle 28 via displaceable shaft 18 and respective one-way clutches 50, 51. These clutches prevent rotation of input shafts 29, 27 whilst the lifeboat is being lowered. One-way clutch 50.-This connects input shaft 29 with hoisting shaft 18. The hoisting drive from motor 31 therefore passes to drum 5 via square-end 29A, input shaft 29 (displaceable by handle 32), one-way clutch 50, hoisting shaft 18, disc 19 fixed on shaft 18, hub 14 driven frictionally by disc 19, and via gearing 13, 12, 11 and 10. In the lowering direction, the weight of the lifeboat drives drum 5 and the speed of lowering is governed automatically by centrifugal brake 16 carried by hub 14, and manually by handle 26, operation of handle 26 causing advance of threaded bush 25 to press disc 19 against hub 14 whilst free-wheel coupling 21 prevents the rotation of the disc. One-way clutch 51.-Alternatively, input shaft 27 is rotated and advanced by the operator using handle 28 so as to make one-way clutch 51, the handle driving drum 5 via clutch 51, disc 19 (which now acts on a clutch), hub 14 and via gearing 13, 12, 11, 10. When motor 31 is out of order, drum 5 may be driven by a deck winch via auxiliary drum 33.

A detector 7 receives a spot beam of light transmitted through a moving strip of paper or textile 1 and from a pattern of the frequency distribution of the detector output the structure of the paper or textile can be determined, so revealing for example weaving mistakes in textiles or the quality of paper. The detector output after amplification at 11 passes to twenty five passband filters 12 to 14 whose outputs after rectification and amplification charge individual capacitors 21 to 23. After the whole of the moving strip has been scanned each capacitor voltage is read in turn and recorded on a pen-chart 27. The scanning is started by control 30 which simultaneously releases a magnetically operated brake 4 and presses roller 3 against a continuously running roller 2. A further detector senses the end of the strip to stop the scanning or in another arrangement a timing device is used. The two extra contacts on the switch 24 enable amplifier 11 to be adjusted for sensitivity and a calibration input to be applied at 34.

Title: Process for the exchange of hydrocarbon groups between aluminium and boron hydrocarbon compounds
IPC: C07F5/02
Filed: 1959-01-20
Abstract: An exchange of hydrocarbon groups between aluminium hydrocarbon compounds and boron hydrocarbon compounds is effected by reacting together two such compounds in which the hydrocarbon radicals are different.  Thus a boron hydrocarbon the hydrocarbon radicals of which are of higher molecular weight than those of the boron hydrocarbon to be produced may be reacted with an aluminium hydrocarbon, the radicals of which are the same as those in the desired boron hydrocarbon, and the reaction mixture distilled to recover the boron hydrocarbon which is the most volatile component of the mixture.  Boron hydrocarbons the radicals of which are of lower molecular weight than those of the desired boron hydrocarbon may be reacted in the cold with an excess of an aluminium hydrocarbon, the radicals of which are the same as those in the desired boron hydrocarbon and the mixture hydrolysed to decompose the aluminium compound and recover the desired boron hydrocarbon, for example with water or dilute sulphuric acid in the cold.  Straight chain olefines may be reacted with diborane to form a boron trialkyl which is then reacted with an aluminium hydrocarbon to form the corresponding aluminium trialkyl.  Lower boron alkyls formed as secondary products may be reconverted to diborane by hydrogenation.  An aluminium triphenyl is obtained by reacting boron triphenyl, or the reaction product of sodium borotetraphenyl with diethyl aluminium chloride, with aluminium triethyl, distilling off boron triethyl and extracting the aluminium triphenyl, e.g. with hot xylene, in the absence of air. Boron alkyls may be built up by reaction with ethylene to form higher boron alkyls in the presence of catayltic quantities of aluminium alkyls as described in Specification 858,446, and the boron alkyls so formed may be then reacted with the aluminium hydrocarbons to form the corresponding higher aluminium trialkyls.

Abstract: 588,064. Stuffing - box substitutes. BAKELITE, Ltd. Jan. 26, 1945, No. 2147. Convention date, Jan. 28, 1944. [Class 122 (v)] [Also in Group XXIX] Means for preventing or controlling flow of fluid from a fluid-pressure container C along a rod &c. 1 passing therethrough, comprises a casing S<1> secured to the container and having an elastic bushing 24 surrounding the rod and fixed at its ends to the casing, liuiil under pressure being supplied to the space between the bush and casing and maintained at a pressure different from that in the container. The ends of the bush are clamped on to conical seatings 22, 28 in the ends of the casing, the seat 28 being adjustable axially to vary the tension in and bore diameter of the bushing. The invention is shown as applied to prevent or control leakage from a chamber C through which a wire &c. 1, coated with plastic material in an extrusion machine E, is passed for treatment by hot or cold fluid under pressure. Casings S, S<1> carrying elastic sleeves are secured to the inlet and outlet sides of the chamber and are supplied with the same fluid as that delivered to the chamber by a pump 3 or from a boiler. Spring loaded valves 7a, 7b, 11 in the supply lines are adjusted to maintain predetermined pressure differentials between the chamber and casings. These differences vary according to whether the bores of sleeves 24 are greater or less in diameter than the rod. Further, the pressure in S is normally less than that in S<1>. Chambers B, B<1> are also provided for collecting fluid leaking through the sleeves 24 and returning it to a sump. These chambers comprise inner members 31 having baffles 33 ... 36, having central bores increasing in diameter as the distance from the chambers S, S<1> increases, and a further baffle 41 having a bore of less diameter than that of baffle 36. Leakage drains through passages 38, 42 to the sump. The invention may also be applied to controlling escape of lubricant from pressurelubricated bearings along shafts.

Abstract: 509,717. Disc brakes ; fluid-pressure brakes. KATTWINKEL, H. Jan. 24, 1938, No. 2241. Convention date, Jan. 28, 1937. Addition to 476,339. [Class 103 (i)] In one modification of the invention of the parent Specification the loose disc carrier is formed of twin discs C<1>, Fig. 1, of stepped cross section, and in other modifications the carrier C is supported on a bearing 15a, Fig. 2, within the annular body D fixed to the vehicle frame and projecting into an annular cavity between the wheel axle and the brake discs. In Fig. 1 a casing E<1> E<2>, E<3>, is fixed to the wheel 1. The discs 14 are splined to casing E<3>, and the discs 11 to a carrier C which is adapted to be locked to the vehicle frame when braking takes place by fluid pressure bellows A and shoes 8 mounted on an annular body D fixed to the axle 3 and also carrying fluid pressure devices B which apply'the braking pressure to the discs. The carrier C comprises a central part C3 on which by means of bolts 13a slide the parts C<1>. Cooling air enters by ducts 28. In the modification shown in Fig. 2 the discs 14 are splined to carrier C and the part E acts as a casing only. The carrier C is adapted to be locked to the wheel 1 by triangular section brake shoes 8a splined to the carrier C. The carrier runs by means of needle bearings 15a on the hub D and fluid to operate the bellows A is supplied by passages 63, 65, and between packing 64. Bellows B supplied by a pipe 25 act directly on the discs. Cooling medium passes through passages 67, 18b, the discs and passage 68 and is circulated by centrifugal force. In a modification of this form the bellows B are not in line with the discs but are nearer the wheel axis and act on the discs through pressure rings of stepped cross section. In a further modification the discs .are arranged in a single group. The apparatus is arranged for relieving the break pressure as the speed drops and the friction increases and for this purpose the annular body D is mounted on the axle 3 by means allowing limited relative movement opposed by springs. Arms are fixed, one on the body D<1>, the other on the axle. Between the arms is a fluid-pressure bellows. As the vehicle comes to a standstill the grip of the brake shoes increases, the arms are therefore moved relatively, compress the bellows which operate a valve releasing the braking pressure. This valve comprises a piston 78, Fig. 7, adapted to be forced up by bellows 82 to which pressure is admitted by the driver in order to connect pipe 86 to pipe 91 leading to bellows B and thus apply the brake. A piston valve 79 is adapted to be operated by the bellows 80 due to the increased grip of the brake shoes and to close the connection between pipes 86, 91, and also to open pipe 91 to atmosphere by passages 88, 89a.
