Title: Improvements in and relating to brazing and soldering
IPC: B23K31/02
Filed: 1942-08-04
Abstract: 563,420. Brazing cutting tools. RADIO TRANSMISSION EQUIPMENT, Ltd., and ZANDSTRA, K. A. Aug. 4, 1942, No. 3312/44. Divided out of 8488/41. [Classes 83 (ii) and 83 (iv)] In soldering or brazing cutting-tips such as of high speed steel, tungsten or titanium carbide to the shanks of cutting-tools, the brazing material is melted by high frequency induction heating and thereafter the heating is continued or augmented to increase the temperature to hardening temperature, whereupon the tip is quenched. With copper as the brazing material and tips of high speed steel, the brazing temperature is 1100‹ C. and the hardening temperature 1300‹ C. Quenching is effected by immersion in a liquid such as oil or by an air blast. In brazing tips to double-edged boring tools, a non-oxidizing atmosphere is preferably used, such as of 90 per cent of nitrogen and 10 per cent of hydrogen, or of 75 per cent of nitrogen and 25 per cent of hydrogen if water vapour and traces of oxygen are first removed therefrom. The operation may be effected in a tube of heat resisting glass closed at one end and inserted in the inductor coil. The gas and also the air blast may be admitted through apertures in the closed end of the .tube and the contact for cutting off the high frequency supply may be linked to the control for turning on the air blast.

IPC: F16H39/16
Filed: 1919-02-13
Abstract: 137,638. Smith, R. J., and Smith, J. B. Feb. 13, 1919. Revolving-cylinder pumps.-In hydraulic apparatus for transmitting motion at variable speeds of the type employing a radial-cylinder pump and motor disposed on opposite sides of a stationary valve-plate, the pistons 6, Fig. 1, are kept in contact with cross-heads 7 engaging a floating ring 8, which rotates within an adjustable or fixed eccentrically-disposed ring 11. Extensions 9 of the cross-heads work in guides 10 bolted to the rotors. The cylinders are disposed in series. The stationary valve-plate 17 is provided with ports 16, 18, and with chambers 20, 21 connected to the ports and containing spring-pressed valves 24. Each rotor has a balance chamber 27 connected to one of the chambers 20, 21, and, when pressure is admitted to a chamber 27 by a valve 24, a piston 28 is forced outwards, and the oil pressure reacts on the rotor to hold it up to the valve plate. When there is no pressure in the system, springs 33 hold the rotors up. In modifications, the balancing pistons 28 are contained in chambers in the valve-plate 17, as shown in Fig. 7, and where the motor is always to rotate in the same direction the valves 24 are dispensed with. The central portion of the plate 17 may be made concave to receive a loose plate 66, which is free to swivel but is prevented from rotating. In a further modification, the rotors are kept up. to the valve-plate by forming the couplings between the rotors and their shafts with inclined claws. The apparatus is also provided with cushioning-devices and release and non-return valves, as described in Specification 137,639, [Class 69 (ii), Hydraulic presses &c.]. the cushioning-devices comprising spring-pressed pistons 34 in cylinders 35 communicating with the ports in the valve' 17, the pistons having relief valves 39, which are opened when their stems contact with adjustable rods 40. The release valves 43, 44 communicate each with one of the ports 16, 18, and are operated by cam surfaces 45, 46 on the wheel 13 for setting the eccentric 11.

[Also in Division H1] In making an encapsulation for a semiconductor device a pair of parts are stamped out from malleable sheet metal of high thermal conductivity, one part having a stamped rim surmounting rimmed out walls and the other a flange, and the rim and the flange are arranged face to face to enable cold pressure welding together of the rim and flange. Headers for the encapsulations are stamped continuously from strip or sheet copper where four holes are punched first, followed by a stamping operation to raise a circular rim 3 with thinned walls and finally by a guillotinning to separate the parts. A semi-conductor element 12, Fig. 1, is soldered, brazed or bonded to the centre of the header and two contact areas 13, 14, e.g. the base and emitter of a transistor are connected by gold wires 15, 16 to lead wires 17, 18 passing through glass-metal seals 27, 28 soldered in holes 5, 6 in the header. A cover or cap 9 is stamped from sheet metal, preferably the same as that used for the header, and has a flat annular flange 11. The header is placed with its rim 3 over the flat edge of a cylindrical steel anvil 18a, the cap is placed with its flange on the rim and the upper part 19 of the welding tool is pressed on the flange to produce a cold pressure weld. The header may have a tapered oval shape in plan and it may have a small central platform raised to receive the semi-conductor element. The lugs 23, 24 and the flange beyond the rim 3 may be raised slightly above the general level of the header and only one glass-metal seal may be provided, for a diode, in the header or the cap. The copper strip or sheet material may be gold or nickel plated or aluminium may be used for the parts.

Abstract: 637,175. Coating webs. TECHNICOLOR MOTION PICTURE CORPORATION. Feb. 11. 1947, No. 3960. Convention date, Aug. 15, 1946. [Class 140] Apparatus for applying a stripe of liquid to a kinematograph film comprises an upwardly-directed nozzle 3 for producing one or more fountains of liquid over which the film F is guided by a flanged roll 2 so that its lower side contacts the summit of the fountain or fountains. The nozzle 3, supplied with liquid through a connection 7, has two orifices 4 and is surrounded by a sleeve 6 to catch overflow which is drained by a connection 8. The nozzle is supported by a block 11 pivoted on a back plate 1 at 12, and is retracted from and advanced towards the film by a mechanism comprising a piston 43 operating in a cylinder 41 pivoted at 42 to the back plate 1.

Abstract: 882,823. Percussive tools. OMARK INDUSTRIES Inc. Feb. 7, 1958 [Feb. 19, 1957], No. 4054/58. Class 124. A percussive tool for producing single blows comprises a piston and cylinder, manually controlled means for moving the piston to a position spaced from one end of the cylinder and forming an explosive charge of fuel and air in the space formed, means for igniting the charge and producing a blow, and means for returning the piston to its original position. As shown, a piston 11 in a cylinder 1 has an extension 12 and a rod 40 both projecting beyond the end 4 of the cylinder. A lever 24 having a handle 36 is pivoted at one end to a bracket 25 on the cylinder and at the other to a latch 44, the free end of which engages in a notch 42 on the rod 40. An electric contact 27 mounted on the lever 24 at the opposite end to the latch 44 engages a contact 32 on the cylinder to provide current to a sparking plug to fire the explosive mixture. Movement of the lever 24 in a clockwise direction moves the piston from the end of the cylinder again return springs 76, 78 and opens an inlet valve 20 for the explosive mixture; further movement of the lever enables a cam 54 on the latch 44 to ride upon an adjustable pin 56 and free the latch from the notch, then, since the lever 24 is freed from the force of the springs rapid movement of the lever enables the contacts 27, 32 to close and the explosive mixture is fired. A rod 60 extending through the piston in both directions has a collar 72 in contact with the piston extension 12 and is thus moved by the piston in the working direction. The rod 60 carries a tool, in the example a knife blade C which co-operates with a hook 86, attached to the front end of a tube 70 containing the return springs, to cut the branch B of a tree. The other end of the rod 60 carries an adjustable washer 64 which co-operates with a shoulder 65 in a sleeve 62, which is secured to a projection 10 on the cylinder, to form a stop for the rod.
