Title: Electric switches
IPC: H01H27/06
Filed: 1966-06-02
Abstract: 1,136,550. Key-operated switches. GENERAL MOTORS CORP. 2 June, 1966 [21 June, 1965], No. 24563/66. Heading H1N. A switch member 28 is driven by a keyoperated cylinder lock 14 that is rotatable in one direction from an OFF position, Fig. 2, to an " on " or " ignition " position and then to a " starter " position, and after axial depression by the key is rotatable in the opposite direction to an " accessory " position. The housing 12 has an annular flange 48 provided with diametrically opposed raised portions 50 (Figs. 4, 5), and the lock 14 has diametrically opposed lugs 46 that slide on the unraised parts of flange 48 when the lock 14 is rotated from " off " to " on " or " starting." Rotation in the opposite direction is limited by lugs 46 abutting portions 50. To reach the " accessory " position, lock 14 is moved axially to the right (Fig. 3), against two spring plungers 58 in the housing, until lugs 46 extend beyond portions 50, and lock 14 is then rotated so that lugs 46 slide on portions 50. Further rotation in this direction is prevented by a stop 54 on the lock, which usually travels in an annular recess 62 in the housing, abutting one of the plungers 58 (Figs. 3, 7). Rotation beyond the "start" position is prevented by stop 54 abutting the other plunger 58. If the key is released in the "starting" position, a helical spring 42 retracts lock 14 to the " ignition " position. When lock 14 is rotated from the " accessory " to the "off" position by the key, plungers 58 return the lock 14 to its original axial position of Fig. 2. Member 28 carries a contact plate 30, spring- pressed towards angularly spaced fixed contacts 34 connected to the " ignition," " starter," and " accessory " circuits, and a spring-loaded contact 44 that energizes lighting circuits during " starting." When stop 54 abuts plunger 58 in the " accessory " position, a tool pressed through a hole 64 in the lock depresses plunger 58 to permit further rotation of stop 54 past plunger 58. This brings lugs 46 into alignment with arcuate slots (68, Fig. 5) in portions 50 so that lock 14 can be disassembled from housing 12.

Title: Improved control for electric motors
IPC: H02P7/00
Filed: 1947-09-06
Abstract: 632,840. Control of D.C. motors. GENERAL MOTORS CORPORATION. Sept. 6, 1947, No. 24573. Convention date, Nov. 20, 1946. [Class 38 (iii)] [Also in Group XXXVIII] A control device for a reversible electric motor comprises a pair of switches for controlling rotation of the motor in respective opposite directions and normally held by spring means in contact with a switch-actuator, and a manually operable member for moving either of the switches away from said actuator and thereby energizing the motor, the actuator being movable intermittently towards the moved switch for stopping the motor, under the control of motor rotation. If an arm 110 is moved in a clockwise direction from the neutral position shown, a switch-arm 90 is swung about its pivot and a plunger 94 disengages a lug 95 on a toothed member 82 so allowing contacts 92-93 to close. A spring 105 is additionally tensioned, but, since a prong 89 of a pallet 86 engages one of the teeth of the member 82, the latter is prevented from following the arm 90. Closure of contacts 92-93 energizes a relay 50 so that an electric motor 20 is supplied from a battery 101 and operates as a series machine to lift a load to which it is coupled upon energization of a clutch-coil 46. Contacts 74-75 are successively opened and closed by means of a motordriven cam 70, an electromagnet 193 being intermittently energized to oscillate the pallet 86 and allow members 82 and 91 to advance through intermittent measured steps, in accordance with a definite number of motor-revolutions, before the lug 95 engages the plunger 94 and opens contacts 92-93 to stop the motor. Reversal of the motor is obtained by moving the arm 110 to displace the switch-arm 91, the motor now operating as a shunt machine. The control device 24 may be mounted remotely from the motor 20. For example, the device 24 may be supported on a tractor and connected to the motor, which is mounted on a trailer, through cables and plug-and-socket connectors. The motor may be utilized to raise and lower a plough-share to which it is coupled through screw-and-nut mechanism and speed-reducing gearing. The application to landing-gear for aircraft is also referred to.

Title: Improvements in or relating to wire handling methods and apparatus
IPC: H01R43/052
Filed: 1964-06-12
Abstract: 1,074,045. Making electrical connections. THOMAS & BETTS CO. June 12, 1964 [June 14, 1963], No. 24585/64. Heading B3A. [Also in Division B8] Apparatus for feeding wires 25 to a standard terminal attaching machine 20 comprises a hopper 28 and a rotary feeding drum 30. In operation, individual wires are guided into one of slots 30a formed in the surface of the drum 30. As the drum is indexed around to a feeding station 38, the wire, which may be bent, is flattened into slot 30a by a shroud 31. The drum 30 is indexed by a pawl which is connected to a ram 24 of the terminal attaching machine 20. When it arrives at the feeding station 38 the wire is forced outwardly by an idler wheel 43 into contact with a feed wheel 32 which urges the wire forward into a terminal attaching station 23 of the machine. A similar arrangement comprising an idler wheel (34a) and, a driven wheel (34) pre-positions the wire closely adjacent the end portion (30b) of the drum, Figs. 1, 3 (not shown). As the wire is fed forwardly it passes through a wire guide (46), Figs. 7, 8, 9 (not shown), which includes a spring (48) for urging the wires upwardly to improve gathering of the wire strands by the crimping tool 24a. A rubber stop (51), Fig. 8, may halt the inward movement of the wire and sensing means (50) may control the wire feed. Fig. 2 also illustrates a wire presence sensor 36 which, if no wire is present in a slot (30a), causes a wire-feed pawl (26), Fig. 3 (not shown), to be inoperative and no terminal is positioned in the station 23. The wire 25 having been positioned, the crimping operation takes place, a severing tool 52 cuts the terminal 22 from a strip and the pawl (26) ejects the crimped-on terminal and wire. 'The next terminal is also fed into position by the pawl and the drum 30 is indexed one position while another wire is fed to receive a terminal. In Figs. 11, 12 (not shown), the terminals and wires pass into an exit guide (53) before dropping into a wheeled hopper (54).

Title: Improvements in the manufacture of moulded articles of paper and like felted materials
IPC: D21J3/00
Filed: 1935-09-04
Abstract: 462,359. Moulding pulp. TENNY, H. S. Sept. 4, 1935, No. 24695. [Class 87 (ii)] In the manufacture of loud - speaker diaphragms and other moulded articles from paper and similar felted materials a suction head 12 carrying a screen 19 is immersed in known manner in a pulp vat to form a pulp shape on the screen. The shape which as shown, is in the form of a cone is removed from the screen 19 by a holder 29 shown in Figs. 2 and 3. The holder comprises a cover 33 and a gauze cone 34 which fits over the screen 19. A suction pipe 35 leads into the space between the cover 33 and cone 34 and is controlled by a valve 40. The pulp cone having been sucked off the screen 19 by the holder 29 is transferred to one of the drying moulds 30, 31, 32. The cover 33 of the holder contains a baffle plate 42 which has a circular row of holes 43 formed in its periphery. When the holder with the paper cone attached is applied to one of the drying moulds the valve 40 is closed and a valve 44 opened to admit air under pressure from a pipe 46 which passes through the holes 43 and presses on the marginal portion of the paper cone and causes it to leave the cone 34 of the holder. At the same time suction is applied to the under surface of the drying mould. The drying mould is shown in Fig. 4, and comprises a hollow conical member 50 in communication with a steam pipe 53. The surface of the mould is provided with a large number of fine grooves 54 which communicate with a central suction and pressure pipe 55. The grooves 54 are intersected by a further series of circular grooves. An arm 63 carrying a ring 64 is hinged at 62 to a member 61 fixed to the mould. Attached to the ring 64 is a rubber diaphragm 65. When the paper cone has been transferred to the drying mould the arm 63 is lowered so that the ring 64 surrounds the mould and the diaphragm 65 covers the paper cone. Suction applied to the pipe 55 causes the atmosphere to press the diaphragm 65 and the paper cone against the surface of the mould. While the cone is drying on the mould other cones are being formed in the pulp vat and are transferred to other drying moulds. When the cone has dried the diaphragm 65 is swung back and air passed up the pipe 55 to detach the cone. The cone is then weighed and if of correct weight it is placed on spinning cone 66, Fig. 6, and a measured quantity of cellulosic dope introduced into the centre of the cone. Warm air from a pipe 70 dries the cone. In order that the margin of the formed cone may be thinner than the body portion the suction head 12 as shown in Fig. 3, is provided inside with a partition 77 which restricts the rate of flow of water through the marginal portion of the cone. Specification 405,979 is referred to.

Title: Strap loop securing and severing means
IPC: B29C65/06
Filed: 1974-06-05
Abstract: 1433275 Seaming non-metallic sheet material FMC CORP 5 June 1974 [5 July 1973] 25019/74 Heading B5K In a method of securing a loop of thermoplastic strapping, e.g. of polypropylene, about an article, and severing the loop from a supply, by overlapping an end portion 18<SP>1</SP> of the strapping with a second portion 18 between the portion 18<SP>1</SP> and the supply, pressing an area of the portion 18 against the portion 18<SP>1</SP>, rubbing this area rapidly back and forth against, and longitudinally of, the portion 18<SP>1</SP> to cause melting of the rubbed faces, stopping the rubbing action and pressing the rubbed faces together until they solidfy, the portion 18 is caused to bend sharply transversely thereof about a predetermined line 46 between the area and the supply every time the area is rubbed back and forth to cause the strapping at this line to fail in fatigue and to be severed along the predetermined line. As shown, a strapping tool comprises a base 10 to rest, in use, on an article 12 to be strapped; a strap-tensioning feed wheel 14 operated by oscillation of a lever 16; a member 20 floatingly secured to the base 10; a strap gripper 22 embedded in the base 10; a strap gripping dog 26 pivotable about a pin 24 and which is secured to, or integral with, an operating lever 28 having a curved end 30 in the path of a cam 32 on the lever 16; an oscillatable welding head 34 of a friction welding mechanism 36 and having strap gripping teeth 40; and a strap gripping element 38. In operation, the lever 16 is depressed to lift the dog 26 and the wheel 14 so that the strapping is pulled from the supply, looped about the article 12 and threaded through the tool along the path shown. The lever 16 is oscillated to tension the strapping. Movement of the lever 16 lowers the dog 26 but, during tensioning, the lever 28 is manually operated to hold the dog 26 out of contact with the strapping. After tensioning, the dog 26 is allowed to engage the strapping and the head 34 is lowered and rapidly oscillated to rub the portion 18 against the portion 18<SP>1</SP>. During this oscillation, bulges (42), Fig. 2 (not shown), and 44, Fig. 3, in the portion 18 are alternately formed to the right and left of the head 34. The dog 26 is formed with a rounded corner 48 and the head 34 with a sharp corner 46 and a rounded corner 50. Thus, during oscillation, the strapping is bent vigorously about the corner 46 and builds up internal heat and fails in fatigue so as to be severed along the line of the corner 46.
Patent GB-698019-A (GB)
Title: Di-hydric alcohols
IPC: C07C29/42
Filed: 1951-10-26
Abstract: Alkine diols are continuously produced by a liquid phase reaction between acetylene and an aldehyde or ketone, in which a copper acetylide catalyst is maintained in suspension in the liquid reaction medium in the form of a slurry by the continuous passage of acetylene upwards through the medium, a quiescent zone is maintained in the reaction mixture from which zone liquid is continuously withdrawn, and fresh aldehyde or ketone is supplied to maintain the volume of reaction liquid constant.  The quiescent zone in the reaction medium can be effected by providing a baffled zone near the top of the reactor and this ensures that substantially no catalyst is withdrawn in the crude product being removed.  The catalyst preferably comprises copper acetylide supported on silica gel.  Preferably a catalyst of a particle size between 50 and 100 mesh is used.  The reaction is preferably carried out at a temperature between 180 DEG and 220 DEG  F.  The alkine diol produced may be hydrogenated to give the alkane diol at temperatures of 210-300 DEG  F. and a pressure of 800 to 1800 lb. per square inch in the presence of Raney nickel at a pH value between 7 and 8.  In the example, a copper acetylide catalyst deposited on silica gel is suspended in an aqueous formaldehyde solution; acetylene and aqueous formaldehyde solution are continuously introduced into the reaction, the acetylene being introduced at such a rate as to keep the catalyst in suspension; the overflow of aqueous formaldehyde solution containing 1.4-butine diol is continuously removed from the zone at the top of the reactor where baffles are provided to maintain the reaction liquid in a quiescent state.  The crude aqueous solution of 1.4-butine diol is steam stripped and distilled to give a solution of 1.4-butine diol which is subsequently hydrogenated to give a solution of 1.4-butane diol, which is purified by distilling and extracting with 2 ethyl hexanol.ALSO:A catalyst for the reaction between acetylene and an aldehyde p  or ketone to produce alkine diols consists of a copper acetylide, preferably supported on silica gel.  In an example silica gel is mixed with a solution of copper nitrate and bismuth nitrate in dilute nitric acid; the mixture is dried, calcined, reduced with formaldehyde and then treated with acetylene to give a an acetylide-acetylene complex which is the active catalyst.

Filed: 1951-10-29
Abstract: 714,604. Rotary pumps. SECORD, L. C., and BOYD, W. Oct. 29, 1951 [Nov. 2, 1950], No. 25232/51. Class 110(2) Hydrogen peroxide is supplied to the main and auxiliary catalytic decomposers 23, 21, Fig. 1. by a pump 13 which if driven by an electric motor 14 energized by a battery 31. When a button 32 is pressed, a timer 36 is operated to close a switch 33 whereupon the motor is energized through a resistor 34. The hydrogen peroxide is fed through a check valve 17, a selector valve 19 and a line 20 to the auxiliary decomposer and the gases generated therein are fed to the main decomposer through the valve 19 and a line 22. A bimetallic strip 24a, responsive to the temperature within the auxiliary decomposer, actuates a controller 19a which closes a switch 35, thereby short circuiting the resistor 34, and moves the selector valve to a second position whereby the auxiliary decomposer is by-passed and the main decomposer supplied directly with fuel from the pump. The controller 19a is retained in the said second position by a control 25 which is responsive to the delivery pressure of the pump. A check valve 27 is coupled to the valve 17 so that when one valve is closed the other valve is opened. The valve 27 communicates with, a drain decomposer 29 and has a pressure-responsive valve 27a arranged in parallel with it. When the auxiliary decomposer is by-passed the residual gas generated therein is discharged through the valve 27a to the drain decomposer which also receives any leakage of fuel through the glands of the pump. After a predetermined time has elapsed, the circuit is broken whereupon the controller 19a returns to its initial position, the valve 17 closes and the valve 27 opens to allow the residual fuel to flow into the drain decomposer. In a modification, Fig. 4, the fuel system comprises an inlet valve 37. a drain valve 38, a pressure-operable valve 41 and an outlet valve 39; the valves 37, 38. 39 being electromagnetically controlled by the timer 36<SP>1</SP>. When the button 32<SP>1</SP> is depressed, the timer energizes the motor 14<SP>1</SP> as above and also energizes the electromagnets of the valves 37, 38 to open the former and close the latter. After a predetermined time has elapsed the timer closes the switch 35<SP>1</SP>, deenergizes the electromagnets of the valves 37, 38 and energizes the electromagnets of the valve 39 to close it, whereby the auxiliary decomposer 21<SP>1</SP> will be by-passed. Later on the timer serves to break the circuit thereby allowing the residual fuel to be drained.
