Abstract: 608,886. Perforating by fusion. HANCOCK, L. J.; and CUMBER, W. F. Feb. 12, 1946, No. 4382. [Class 83 (iv)] A blow-pipe cutting machine for cutting holes in circular pipes comprises a frame having supports adapted to be rested on the pipe and a blow-pipe carrier journalled in the frame and rotatable about an axis intersecting the pipe, the blow-pipe being reciprocably mounted in the carrier and moved by a link device connected to the blow-pipe and pivoted about a relatively fixed point so that as the blow-pipe moves the nozzle is simultaneously raised and lowered in accordance with the pipe contour. The blow-pipe 12, which may be angularly adjustable for bevel cutting is carried on a head by a tube 14, which is vertically movable through rollers 17 in a slide 15 radially adjustable on graduated bars 16 on a ring 9 rotatable through gearing by a hand-wheel 11 on a fixed ring 8. The tube 16 is of square section to prevent it rotating relatively to the slide 15. The ring 8 is mounted on a frame 2, 3, attached to the pipe to be cut by a chain 6 and screw clamp. To the tube 14 is secured by clamp 27 a rod 26 mounted in ball or roller bearings 212 on the centre of a forked bracket 39 so that it is rotatable relatively thereto, the forked bracket being connected by ball or roller bearings 211 to a cross-head 21 which carries guide rollers 22 and is slidable on a bar 20 fixed to adjustable links 23 pivoted on axles 24 on pillars 25a, 25b, fixed on the frame 2, the links being approximately equal in length to the radius of the pipe 5. Alternatively the rod 26 may be fixed to the bracket 39 and journalled in the tube 14. Actuation of the ring 9 through the rod 26 moves the slide 21 along the bar 20 and raises and lowers the bar on the pivots 24 so as to follow the contour of the pipe. The links 23 are slotted and secured by clamp nuts 37 according to the diameter of the hole to be cut and the weight of the slide 21 &c. is partly counterbalanced by counterweights 30 carried by adjustable links 31. In order to cut offcentre holes in the pipe the ring 8 and parts mounted thereon may be adjustable laterally on the support 2 against a scale 34 and secured in position by studs and slots 40. For cutting irregular shapes in pipes the slide 15 is provided with a roller on a vertical spindle pressed by compression springs fitted over the bars 16 against a template fixed on vertical supports to the ring 8.

Abstract: 419,575. Toggles. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, POOLEY, A. M., Riverdale, Tixall, Staffordshire, and HEATH, A. A., Lydstep, Rowley Park, Stafford. Feb. 10, 1934, No. 4483. [Class 80 (iii).] A dead centre spring toggle for a snap-action switch comprises a link 1 pivoted on a spindle 2 and driven with lost motion by a handle (not shown). Pivoted to the free end of link 1 by a pin 3, is a link 4 which slidably but non- rotatably engages the upturned end of a link 5 pivoted at 6 to the casing. A spring 7 is mounted in compression between a shoulder on the link 4 and the upturned end of link 5. The pin 3 drives, with lost motion, the switch contact mechanism (not shown) which is also mounted on the spindle 2. The above disposition of pivots gives a longer spring for a given angular movement of the links. In a modification for a heavier type of switch, the link 4 has two limbs carrying two springs and the limbs slide in the cross piece of the link 5 which is then T-shaped.

Abstract: 764,885. Magnetic compositions; eddy current apparatus. EATON MANUFACTURING CO. Feb. 17, 1955 [Feb. 23, 1954], No. 4762/55. Classes 35 and 38 (2). A magnetizable particle mixture for use in a magnetic coupling comprises a major proportion by weight of powdered iron, e.g. Carbonyl-E, Swedish or electrolytic iron, and/ or substantially non-corrodible ferromagnetic alloy, e.g. stainless steel, together with a minor proportion of one or more of the carbides of columbium, titanium, tungsten and tantalum, and/or cobalt oxide.

Title: Electrical pulse generating systems
IPC: H03K17/76
Filed: 1962-02-08
Abstract: 989,436. Electric selective signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 8, 1962 [March 31, 1961], No. 4909/62. Heading G4H. [Also in Division H3] A circuit for driving a current pulse through an inductive line comprises a transistor having an emitter resistor and a base clamping device and having its collector connected to one end of the line and via a resistor to a reverse bias voltage so as to maintain the collector/base capacitance charged. As shown in Fig. 6, all transistors are normally non-conductive. When it is desired to pass a current pulse from right to left in line 1, a positive pulse is applied to the base of transistor T3 so that transistors T4, T5 are also made conductive. A negative pulse applied to the base of transistor T2 drives transistor T1 into conduction so that a constant current pulse travels in line 1 via diodes D1, D2. A current pulse may be driven from left to right by applying control pulses to transistors T<SP>1</SP>2 and T3<SP>1</SP>. Fig. 7 (not shown) relates to a storage matrix in which bipolar pulses may be driven through any one of thirty two lines under control of twelve voltage pulse generators and twelve current pulse generators. Reference is made to control of an n x m matrix by 2(#n + m) drivers. Simpler switching circuits are described (see Division H3). Digital-analogue conversion. Fig. 8 shows an arrangement in which current pulses can be driven in either direction along a selected one of lines 1, 11, 111. Transistors T1 are normally non-conductive; digital data pulses being applied to terminals Gi, the appropriate line being selected by voltage pulses applied to terminals Vg. The amplitude of current pulse in any line 1, 11, 111 is dependent on the values of emitter resistor Re or clamping voltage VX, so that these values are selected so that the constant current through any transistor T1 is weighted according to the value of digital data fed to its base. If more than one transistor T1 is made conductive, the current in the selected line is equal to the sum of transistor currents.

Abstract: 812,853. Flock pile fabrics. VERTIPILE Inc. Feb. 13, 1957 [May 4, 1956], No. 4950/ 57. Class 140. A flock pile fabric comprises a base sheet carrying ornamentally arranged clumps of recumbent flock fibres intermingled and interlocked and bound to the base sheet by a layer of binder material. The surface of the base sheet may have contrasting parts free from fibres, covered by upstanding closely spaced flock fibres of suede or velvet like texture which may predominate in area, and clumps of recumbent fibres which may be of various sizes and colours and be such that the exposed faces thereof are substantially level with the tips of the upstanding fibres. The fabric may be produced by coating a base fabric 20 with an adhesive 25, depositing clumps of wet fibres 30 thereon in a predetermined pattern from apparatus 27 which comprises a hopper 28 having an apertured or screened bottom 29, depositing short individual thoroughly dried flock fibres 32 on to the fabric from apparatus C prior to passage over polygonal roll E, which creates static electricity by vibrating the base fabric, and under suction mouth D, which causes the individual fibres to stand erect and removes unsecured fibres. Additional fibre depositing apparatus F, polygonal roll H and suction mouth G may be employed to assure that web 20 is thoroughly covered with pile fibres 32 prior to passage through oven I and rolling on roll J. The clumps of fibres may be liquid dyed and dried, e.g. by centrifugation, to a moisture content of about 50 per cent before being screened to a predetermined size.
