Title: Improvements in or relating to methods of cutting tubes into lengths and apparatus therefor
IPC: B26D3/16
Filed: 1932-05-09
Abstract: 402,077. Moulding and cutting rubber and like tubes. INDIA RUBBER, GUTTA PERCHA, & TELEGRAPH WORKS CO., Ltd., Aldwych House, Aldwych, MATTHEWS, F. C., BROWN, F. E., and PENGELLY, J. W. H., c /o India Rubber, Gutta Percha, & Telegraph Works Co., Silvertown, London. May 9, 1932, No. 13327. [Class 87 (ii).] Apparatus for cutting tubes into lengths, of the kind in which the cutters travel at the speed of the moving work during the cut, is arranged so that the cutter-holding means moves in a path strictly parallel to the axis of the tube. As applied to the cutting up of rubber tubing for the manufacture of hollow articles such as balls, a tube 15 of unvulcanised rubber issuing from an extrusion machine is cut into lengths by reciprocating cutters and the lengths preferably are divided again by being cut at the centre and also closed and sealed by two semi-circular pressing and cutting dies, thus forming blanks for the manufacture of rubber balls. Usually the two cutting-frames 86, 88, which slide on the three guides 10-12, are connected together adjustably so that both are reciprocated from the cam 52 through the linkage 50, 46 connected to the trunnions 47. A second cam 54 moves an inner ring 28 angularly relatively to the frame 86 through the linkage 35, 34, 38, the last link 38 having balljoints at each end to permit the sliding movement of the frame. This movement of the ring in one direction moves the cutters 24 radially inwards through the cam slots 22 acting on the cutter-pins 32. A third cam 80 moves the cutters 66 on the guides 63 through the medium of the lever 84 and mutilated tcothed gear 86, 76, 71, 73, 68. The speed of the sliding movement of the frames is increased at the point where the cutters 24 are finishing their cutting movement, so that it is momentarily greater than the feed of the tube, thus allowing the cut portion to be severed completely from the bulk. To remove the waste portions cut away by the cutting dies 66, spring plungers 91, Fig. 7, fitting between the dies are depressed during the cutting and stamping operation and remove the waste portions on being released.

Filed: 1937-05-11
Abstract: A paint base of liquid or solid form comprises an oxidized mixture of a drying oil and the still residue obtained in the distillation of oil, produced in coking coal, to recover benzene, toluene, xylene, and addition and substitution products of aromatic hydrocarbons, the residuum being in the form of an oily liquid residue comprising lower polymers and heavy monomers. Equal volumes of still residue and fish oil are heated in a still provided with coils for circulating steam and coils for blowing in air, the temperature being raised to 170 DEG F. before the air is admitted and being kept at this temperature while blowing in air for 5 1/2 days.  The viscosity of the liquid is increased from 150 to 1800 Saybolt and the iodine value decreased from 158 to 91.  The proportions of the mixture may be varied.  In a further example 80 volumes still residue are mixed with 20 volumes of drying oil and the mixture blown with air at 195 DEG  F. for 6 1/2 days.  An elastic solid is obtained which may be cut back with 40 per cent aromatic solvent, e.g. coal-tar naphtha or 60 per cent mineral spirits.  The drying oils may be given a slight preliminary oxidation to prevent foaming.  The oxidation may be accelerated by using oxygen, ozonized air, or oxidation &c. catalysts, e.g. manganese, lead, cobalt resinates, oleates &c.

Patent GB-1498666-A (GB)
Title: Pulse generator circuits
IPC: H03K3/017
Filed: 1975-04-03
Abstract: 1498666 Multivibrator; remote control of receivers SONY CORP 3 April 1975 [4 April 1974] 13759/75 Headings H3T and H3Q A multivibrator 21, 22, Fig. 6, which is referred to as being "on" when T22 is conducting, has its "on" time made substantially independent of supply voltage variations by connecting the emitter of T21 to the output of an emitter follower T36, R31, rather than to earth, as in the prior art, (Fig. 1, not shown), so that when T21 is non-conducting its emitter voltage follows any supply voltage variation. The "on" time of the multivibrator is determined by the time taken for a capacitor 27 to charge via a resistor R (R being any selected one of resistors 30A, 30B, ...,) to a voltage sufficiently high to make T21 conductive. In the prior art this voltage was constant being just the appropriate base-emitter drop, and if the supply voltage fell the rate of charging also fell and the "on" time increased. In accordance with the invention, however, the voltage to which C27 must rise is the base-emitter voltage, as before, plus the output voltage V E  of the emitter follower 36, so that if the supply voltage falls, reducing the rate of charging of C27, the voltage to which it must charge also falls, in a compensatory manner. The multivibrator is said to be for gating repeated bursts, of selectable width, of an oscillator 38 for the remote control of a television receiver.

Filed: 1945-06-01
Abstract: 592,743. Operating vehicle door windows. TRICO PRODUCTS CORPORATION. June 1, 1945, No. 13844. Convention date, June 2, 1944. [Class 20(iii)] [Also in Groups XXVIII and XXXVI] In a motor vehicle in which a power line leads across the hinge axis of a door &c. to a motor for operating a window, the line is fixedly supported at two spaced points substantially on the hinge axis by members attached to the door and door pillar respectively, so that the portion between is substantially coincidental with the hinge axis and is thus subjected to twisting only when the door is moved. As shown in Fig. 1, the door 1 has a vertically slidable window operated by a fluid motor 6 through a control valve 14 as in Specification 564,867. This valve has two control lines 21 connected to a point on the door. A power supply line 12 from the intake manifold of the engine and two control lines 19 from the instrument panel are carried across the hinge axis 3 by means of a member 28 on the pillar and a channel arm 24 fixed at one end to the door by a bracket 25, Fig. 3, the other end lying on the hinge axis.

Patent GB-639001-A (GB)
Title: Improvements in or relating to garment presses
IPC: D06F71/02
Filed: 1947-05-24
Abstract: 639,001. Ironing-presses. CHERRY TREE MACHINE CO., Ltd., and DOWELL,. G. May 24, 1947, Nos. 13992 and 20911. [Class 138 (ii)] In a manually-operable garment press, upper and lower pressing elements 11, 21 are brought together by a foot actuated toggle mechanism 14; 15 comprising a bell-crank lever 14 having a foot plate 12 associated with one limb, the limb being connected to a fixed point on the machine frame by a rule-jointed linkage 19, 20 which when fully extended holds the foot-plate 12 depressed and so maintains pressure between the pressing elements 11, 21. The toggle mechanism 14, 15, Fig. 1, is prevented from reaching its deadcentre position by the rule-jointed linkage 19, 20 comprising a toggle which is pivoted to the bell-crank 14 and to the machine frame ; an extension 19a on the link 19 engaging a pin 23 on the link 20 so that the linkage can move in one way only, so locking the foot plate 12 in an operated position. The head is released when the toggle 19, 20 is broken by means of a pin 25 on a lever 24 which is pivoted at 18 and operated either by a foot pedal 26 or a hand lever 27. As shown in Fig. 5, the foot plate 50 and the lower link 51 of the locking toggle may be a single member pivoted to the lower member of the head operating toggle at 52. The foot pedal 26, Fig. 1, and the lever 27 are connected by linkage through a bellcrank 29 which is mounted coaxially with the hand arm pivot 16 and which has a pin 35 engaging a slot 34 in one of the connecting links 31b to the pedal 26. With the hand closed the pin engages the upper end of the slot and so either control may release the head. When the head opens the pin slides down the slot so that only the foot pedal 26 can then control the head. The same type of interconnection may be used between the hand and foot controls of a steam valve mounted on the head. Because of the pin and slot connection, when the head is raised, only the hand control which is mounted on the head, can operate the steam valve, but in a modification, Fig. 4, the bell-crank 42 has a positive engagement with the foot pedal link 39b and is pivoted on the head arm 10 so that the connection between the hand and foot controls is substantially unaffected by movement of the head and either can control the steam valve at all times. The head release controls may be similarly connected.

Title: Improvements in or relating to hydrostatic transmission systems
IPC: B60K17/10
Filed: 1960-04-21
Abstract: 876,140. Hydraulic transmission of power. INTERNATIONAL HARVESTER CO. April 21, 1960 [April 22, 1959], No. 14013/60. Class 69 (2). [Also in Group XXXI] In an hydrostatic transmission system comprising two fluid motors operated from a common pressure fluid source an automatic means is provided for controlling the relative speeds of the motors comprising a flow divider having a pressure fluid inlet, two ports communicating with the respective motors and a valve member movable against resilient means in response to a pressure differential between the two ports whereby the relative flow distribution is altered to maintain the fluid motors with a selected speed ratio by increasing the flow to the higher pressure port and vice versa. In the construction shown an engine 10 drives a pump 12 supplying fluid to motors 31, 31<SP>1</SP> through a flow divider 16. Servomotors 34, 341 responsive to the motor supply pressures operate to increase the output torque of the motors when the pressure rises by pivoting the motors 31, 31<SP>1</SP> within the casings 25, 25<SP>1</SP> to increase the motor piston displacements. Normally the valve member 58 (Figs. 1 and 5) is held in a central position in the flow divider 16 by a pair of springs 55, 57 in chambers 63, 64 which communicate through ports 61, 62 and pipes 24a, 24a<SP>1</SP> with the pipes 24, 241 from the flow divider outlets 17, 18 to the motors. Should wheel 30 skid or slip the pressure will drop in the motor 31, pipe 24 and chamber 61, allowing the valve member 58 to rise, Fig. 1, decreasing the area of port 17 and increasing the area of port 18 and thus decreasing the relative flow to wheel 30. Meanwhile the reduced pressure on the servomotor 34 causes it to reduce the piston displacement of the motor and hence its. torque output. Simultaneously the pressure rises in line 24<SP>1</SP> as the load on the motor 31<SP>1</SP> increases operating servomotor 34<SP>1</SP> to increase the piston displacement and torque output of the motor 31<SP>1</SP>. The valve member and servomotors are so chosen that as the displacement and fluid flow of the motors alters the speeds remain sensibly equal. Fig. 2 shows an alternative form of valve member 44 movable in response to pressure differential between its end faces. There is provided a connection with the steering means 19, 20, 20a whereby the outer wheel on a curve will travel faster than the inner wheel comprising a threaded bracket 22 and frame 23 which move the spring seatings longitudinally to displace the valve member from its central position. The flow divider may also be applied to vehicles with constant displacement motors.

Abstract: 897,356. Electronic counting - apparatus. GENERAL RADIO CO. April 21, 1960 [June 24, 1959], No. 14080/60. Class 106 (1). A counter comprising decade counting circuits is adapted to count a predetermined number N of pulses and has means for recognizing a pulse preceding the Nth pulse thereby to produce an output pulse adapted to reset the counter immediately after the Nth pulse. As shown, Fig. 1, pulses Fig. 2A to be counted are applied to the input of a three-decade counter having " reset " switches S 1 -S 3  set to the number to which the counter is to be reset and " recognition " switches S<SP>1</SP> 1 -S<SP>1</SP> 3  connected to an " and " gate 10 adapted to produce an output, Fig. 2, B, immediately after the (N-1)th pulse. The gate 10 controls a gate 12 which is also supplied via an inverter 14 with the inverted input pulses, Fig. 2, C, so that the inverted N'th input pulse, Fig. 2, D, is passed to a pulse stretcher and amplifier 16 to produce a reset and output pulse, Fig. 2, E, adapted to reset the counter to the state determined by the switches S 1 -S 3 . A detailed circuit for the components 14, 12, 16 is described (Fig. 3, not shown). In a second embodiment, Fig. 4, the (N-2)th pulse is recognized in the counter 50, which comprises ring-type decades, a gate 52 being opened, the output of which, corresponding to the (N-1)th pulse, is applied to the " 0 " input of a flip-flop 56 which is thereby changed over to its " 0 " state. This changing-over of the flip-flop 56 results in a potential rise at its " 1 " output and a potential drop at its " 0 " output. These potential changes are differentiated at 58, 60, the negative pulse from the differentiator 60 triggering a blocking or other oscillator 62 to produce a negative pulse during the interval between the (N-1)th and N'th input pulses to clear the ring counters 50. The Nth input pulse resets the flip-flop 56 to its "1 " state to produce a potential drop at the " 1 " output which gives rise to a negative pulse from the differentiator 58 to produce a counter reset pulse between the Nth input pulse and the first input pulse of the next series.
