Title: Improvements in or relating to the oxidation of hydrocarbons
IPC: C07C4/02
Filed: 1938-06-29
Abstract: 516,587. Oxidation of hydrocarbons; acetylene. DU PONT DE NEMOURS & CO., E. I. June 29, 1938, No. 19344. Convention date,. June 29, 1937. [Classes 2 (i) and 2 (iii)] The partial oxidation of hydrocarbons is effected by introducing hydrocarbon at two or more successive points relatively close together into a stream of an oxidizing gas, e.g., air or oxygen, heated to a temperature equal to or above the ignition temperature of the hydrocarbon. The process is particularly useful in the production of unsaturated hydrocarbons, such as acetylene, by partial oxidation of other hydrocarbons, particularly hydrocarbons containing 3-7 carbon atoms in the molecule. The ratio of oxidizing gas to total hydrocarbon is less than that necessary to convert all of the hydrocarbon .into carbon monoxide and water, and is generally 20-60 per cent. of that ratio: The reaction products should be rapidly cooled, and for this. purpose they may be mixed either with a relatively cool gas or vapour, e.g., steam, or with previously cooled reaction products from which the desired reaction products may or may not have been extracted. Suitable apparatus comprises a reaction chamber 1 having an inlet 2 for preheated oxidizing gas, and a hydrocarbon inlet 3 comprising a central inlet 4 and an annular inlet 5 ; the inlets 4, 5 are provided with openings 7, 6 respectively, the openings 7 being below the openings 6. A cooling agent is led in through an inlet 8, and the reaction products are withdrawn through a pipe 9. A part of the air may be mixed witb the hydrocarbon fed to theinlet 3. Examples are given illustrating the production of acetylene by the partial oxidation of butane, natural gas, butylene and heptane with air. Specification 264,845, [Class 2 (i)], is. referred to.

Title: Improvements in or relating to cardiac stimulators
IPC: A61N1/362
Filed: 1963-05-16
Abstract: 983,773. Cardiac stimulators. COTELEC SOC. FRANCAISE D'ETUDES ET DE CONSTRUCTIONS ELECTRONIQUES. May 16, 1963 [May 17, 1962], No. 19492/63. Heading A5R. An implanted cardiac stimulator is associated with a switching circuit controlled by an external monitoring device which causes the operation of the stimulator to stop if the heart is functioning normally. A pick-up device 2, strapped to the patient in the vicinity of the heart produces signals, in response to the heart's beating, which are amplified and rectified and then employed to charge a condenser 17. A variable leak 19 is connected across the condenser but, if the signals are received with sufficient frequency, a charge is built up which actuates a pulse generator 20 and high-frequency generator 3 to transmit a signal from an antenna 4 placed close against the patient's skin. A pick-up loop 7 receives this signal which is rectified at 10 and raises the base voltage of transistor 12, to cut off the transistor and stop the operation of the stimulator generator 14. If the action of the heart slows down or stops, no signal is passed by the controlling circuit, the base of the transistor goes negative, owing to its connection through a resistor 16 to the battery 13a. The transistor then passes current and the stimulator 14 commences to operate.

A lipstick-holder comprises a tubular case 12, a rotatable base 4 with known mechanism for projecting the stick when the base 4 is rotated relatively to the case 12, a cap 13 enclosing the case and engaging with with base, and a freely rotatable member 14 at the junction of the cap 13 and the base 4 to allow idle turning of the case 12 within the cap 13 rather than actuation of the mechanism when the base 4 is rotated relatively to the cap 13. The member 14 is in the form of a ring with beads 15 to grip the inside of the cap mouth tightly. The ring may be replaced by small balls freely rotatable but captive in spaced sockets in the base portion or the mouth of the cap.

Abstract: 1,046,103. Stapling machines. SPEEDFAST CORPORATION. May 21, 1963 [May 31, 1962], No. 20159/63. Heading B4C. A stapling machine adapted to receive a plurality of interconnected fastener elements comprises a feed mechanism 55, 27 having a cam means movable against the action of a spring 61 by a driver blade 32, and means for interposing a fastener element in advance of the cam means when the cam is moved against the action of the spring. The fasteners are in the form of a reel of interconnected blanks mounted in a magazine 13 which is enclosed by a hinged cover 14 locked by means of a latch mechanism 18, 24, 30, a serrated roller 27 being urged by a spring 29 in order to press the free end of the strip of fasteners against an anvil member 55. The driver blade 32 is mounted on a plunger 35 actuated by a lever 37. A staple forming blade 33 and a pair of clenching anvils 41, Fig. 11 (not shown) are also mounted on the plunger, the anvils being connected by links 43, 44 to the plunger and pivoted to an adjustable slide 46. In operation, when the lever 37 is depressed the plunger moves downwardly so that the driver blade contacts a projection 60 on the cam 58 thereby moving it rearwardly so that the former blade may bend the legs 17 of the staple against the anvil 55. The lever is then released so that the cam 58, under the action of the spring 61, presses against the legs of the staple which is still connected to the strip thereby moving the pre-formed staple into the driving position. When the handle is next operated, the driver blade shears the pre-formed staple from the strip and drives it through a workpiece, continued movement of the plunger causing the pivoted clenching anvils to pierce the workpiece and then clench the legs of the staple; the degree of clenching may be adjusted by means of a screw 48 connected to the slide 46.

Abstract: 531,055. Refrigerating. GENERAL MOTORS CORPORATION. July 11, 1939, No. 20170. Convention date, Aug. 13, 1938. [Class 29] A compartment 40 of a domestic cabinet having the usual evaporator 52 in the upper compartment 38 is cooled by a secondary closed heat-transfer system having a condensing element 68 removably clamped to the bottom of the evaporator 52 and an evaporating element in the form of a coiled pipe 98 wound round the outer face of the sides, back and bottom of the metal lining 32 of the cabinet. The evaporator 52 has hair-pin shaped conduits 62, 64, Fig. 4, on its bottom face 66 connected to the usual header conduits 60, and the condenser element of the secondary system comprises pipes 70, 72 secured in contact with the evaporator ' conduits by removable clamps 76. The stretches 98 of the secondary system pipe are held in place on the cabinet liner by upright clamps 92 screwed to the liner, the shelf supports 140 of the cabinet interior being secured by the same screws. To ensure unidirectional circulation in the secondary system the vapour conduit 104 extends as a goose-neck trap above the condenser element and the outlet 82 of this element is below the level of the inlet 80. The secondary system is mounted on the liner before the liner is placed in position by insertion through the door opening, and hot asphalt is poured over the coil stretches to ensure good heat transfer between the coil and liner. Preferably the lower part of the liner is wrapped in heavy wrapping paper prior to insertion to avoid disturbance of the glass wool insulation. The liner is secured in place by the usual " breaker " strips 34, Fig. 3. The partition 42 separating the two compartments consists of a single or double glass plate having a rubber packing 48, Fig. 2, around a metal channel member 50, and may be adjusted to any shelf position. The evaporator 52 is removably secured to the top of the liner and may be removed without disturbance of the liner 76 of the secondary system after release of the clamps through an opening in the back of the cabinet closable by a panel having a packed cover plate on the outside, the liner having a corresponding opening closable by a pair of plates 112, 114, Fig. 1. Shields 130, 132 spaced from the sides of the evaporator by insulated spacers 134 are supported from the top of the liner and serve to reduce the cooling effect in the upper compartment. The evaporator is supplied from the usual condenser &c. 122 in a base compartment, and the supply conduit 118 may be of capillary dimensions and be soldered to the return conduit 120. The secondary system is charged through a sealable branch 106 with a volatile medium such as difluordichlorethane, with or without an inert gas. A lip 160 is provided at the front of the liner at the bottom to prevent flow of moisture out of the doorway. Specification 349,798 is referred to.

The air supply from a blower 29 is also controlled by a spill valve. The exhaust gas issues through an adjustable valve 35. At starting, reservoirs of compressed air and gas are connected directly to the cells 27, 26.
