Title: Improvements in clutch and/or brake mechanisms
IPC: F16D25/0635
Filed: 1941-03-28
Abstract: 553,498. Disc brakes. ABBEY, A. (Bliss Co., E. W.). March 28, 1941, No. 4241. [Clzss 103 (i)] [Also in Group XXIV] A friction clutch comprises a plate 24, slidable on pins 25 on a pulley 7, adapted to be clutched between a plate 35 and member 37. The plate 35 is fixed to a shaft 5 and the member 37 is axially slidable thereon. A brake comprises a plate 30 slidable on pins 32 carried by a fixed frame 34, the plate 30 being adapted to be clamped between the member 37 and a plate 83 carried by a cage 20 fixed to the shaft 5. The brake and clutch are alternately engaged by axial sliding movement of the member 37. The plate 83 is carried by blocks 86 which are slidable in the cage 20 and engage rollers 97 carried in tapered recesses 95 so that the plate can move to the right but not to the left. A flange 100 on the member 37 engages with clearance 104 behind the plate 83 so that in the disengaged condition of the brake the members 37, 83 are always the same distance apart. Thus as wear occurs in the friction clutch members the member 83 progressively moves to the right. The member 37 is moved to the left by springs 75 and to the right by fluid pressure acting upon pistons 50 carried by the cage 20. Each piston 50 engages a lever 60 loosely pivoted upon a pin 62 carried by the cage 20. The lever has faces 64, 68, engaging the member 37 and cage 20 respectively. The surface 68 is substantially cylindrical and co-axial with the pivot. The pins 62 are thus subjected to very little pressure. Spring-urged pins 70 keep the levers 60 in contact with the pistons 50 when the fluid pressure on the pistons 50 is released.

Title: Improvements in or relating to cutting presses
Inventor: BARKER WILLIAM ARTHUR
IPC: C14B5/00
Filed: 1967-01-31
Abstract: 1,210,655. Cutting-out presses. BRITISH UNITED SHOE MACHINERY CO. Ltd. 30 Jan., 1968 [31 Jan., 1967], No. 4556/67. Heading B4B. A press for cutting-out blanks from a lay of sheet material comprises a knife 14 mounted on a carriage 12 and movable towards and away from a table 5 to effect cutting, the carriage being movable along a beam 10 under the control of a tape 23 provided with abutments 26, 28 adapted to contact cams 61, 63 so as to stop the movement of the carriage. The carriage 12 is movable along the beam 10 by means of a chain 39 passing over sprockets 35, 37, the sprocket 35 being rotated by means of an hydraulic motor M via gears 32, 34. The motor is controlled by means of the tape 23 which passes over pulleys 27, 29 and is arranged to be selectively clamped to the carriage 12 by means of piston-actuated clamps 40, 42. The stop means comprises a plate 50 adjustably mounted on the frame of the press and supporting the cams via pivoted levers 62, 72 and link 84. The link 84 is also connected to a lever 80 having a roller 82 which is arranged to act on a plate 90, the plate being connected to levers 96, 98, Fig. 5, adapted to actuate a valve M1 via a rod 112. In operation, with the apparatus in the position shown in Fig. 2, wherein the clamp 42 grips the tape, the abutment 26 contacts the cam 66 to maintain the valve M1 and a knife ram actuating switch LS9 both in the closed position, a push-button A, Fig. 1, is operated to thereby actuate the ram so that the knife descends and effects a cutting stroke. At the bottom of the stroke, a switch LS11 is actuated to reverse the direction of the ram and change over the position of the clamps 42, 40, the clamp 40 now gripping the tape. At the upper position of the knife ram a switch LS6 is actuated to thereby energize a valve SV2 so that pressurized oil passes therethrough and, via a reversing valve SV1, rotates the motor M thereby causing the carriage to move from right to left when facing the press. The tape now moves with the carriage until the abutment 28 contacts the cam 63 so as to close the valve M1 and stop the motor M. The movement of the cam 63 again causes the switch LS9 to be actuated so that the knife effects a second cutting stroke as described above, the clamps 40, 42 again being reversed so that a third complete cycle can be initiated. Upon completion of the third cycle switches LS8A, LS8B, Fig. 2, are actuated so as to cause the table 5 to move and bring an uncut portion of the lay under the knife and, also, reverse the position of the valve SV1; the same cycle of movements of the qarriage as described above is then effected from left to right. When, after a certain period of cutting, the knife becomes full of blanks they actuate a switch LS4 thereby initiating the movement of the carriage to an ejection station 20 so that upon actuation of a switch LS10, the blanks are ejected. The knife can be rotated about a vertical axis in order that the best position for the cut can be determined.

Title: Improvements in gas blanketed arc welding
IPC: B23K9/007
Filed: 1948-02-17
Abstract: 637,146. Uniting by fusion. LINDE AIR PRODUCTS CO. Feb. 17, 1948, No. 4578. Convention date, Feb. 28, 1947. [Class 83 (iv)] Intermittent arc welds are made by directing an inert gas blanketed non-consumable electrode to a zone of the work striking an arc between the electrode and a central portion of the zone maintaining the arc until the work fuses and maintaining the electrode and. the zone of gas stationary for the duration of the arc. After the gas is turned on the arc is struck after a predetermined time interval. The torch comprises a holder 10 with grip G for electrode E and an inert-gas tube 14 supplying a ceramic cup 20. A metallic cover 21 is supplied with cooling water by pipe 25, tube 26 and flexible pipe 27. An electric cable 34 is soldered to a pipe 32 which exhausts the cooling water and supplies the welding current. A trigger T controls a switch K of a timing device. A timer 37 in series with the switch K controls the inert gas supply. When the switch K is closed by trigger T a solenoid valve 40 is operated through normally closed contacts 38 to turn on the gas supply to a tube 24 and to start the timing period of the timer 37. After an interval the timer 37 closes contacts 39 and through closed contacts 48 of a weld timer 47 energizes a relay 41 to close contacts 42 of a welding transformer 43. The welding circuit includes a H.F. starting unit R which establishes the arc and permits current to flow through the electrode E and the work U. The welding current energizes a relay 45 to close contacts 46 of the weld timer 47 which times the duration of the weld. After the time interval relay 47 opens contacts 48 to de-energize relay 41 to open contacts 42 to de-energize the transformer 43. The weld timer 47 at the same time closes contacts 49 in parallel with contacts 46 of welding current relay 45 to reset the timer. Gas continues to flow until the timer 37 opens contacts 38 to operate the valve 40. Release of the trigger T opens the switch K which resets the timer 37. A switch 50 may be employed to cut out manually the timer 47 in which event the duration of the weld is governed by the length of time the trigger T holds the switch K closed. In a modification, Fig. 4, not shown, the electrode is advanced through the nozzle to locate the weld and is then retracted, the nozzle is pressed into contact with the work and the gas and welding current are turned on in timed relation to the pressure of the nozzle on the work.

Abstract: 662,951. X-ray tubes. PHILIPS ELECTRICAL, Ltd. Feb. 21, 1949 [Feb. 23, 1948], No. 4678/49. Class 39 (i). [Also in Groups II and XXXIV] In an X-ray tube having a rotary anode of which the rolling parts are covered with a soft metal layer functioning as a lubricant, a supply of the soft metal is carried within the envelope for renewing the lubricating layer by vaporization. The soft metal, which may be lead, tin, cadmium or zinc, is contained in a cup 15 attached to the anode shaft 8 and adjacent to the inner ball-race 7, which becomes hotter in operation than race 6, rising to about 350-400 C. Movement of the rolling parts tends to harden the lubricating layer, but the high temperature causes it to soften and vaporize. The replenishing supply in the cup 15 is hotter still than the bearings 7; and so a constant formation of a fresh deposit vaporizing on to the moving parts takes place. The rotor 13 and anode support 5 enclose between them a narrow cylindrical duct communicating with the discharge space, the temperature gradient along 13 being such that the metal vapour condenses before reaching the discharge space. The cup 15 is covered with gauze, or the soft metal may be incorporated in a porous body of a metal of higher melting-point, or be alloyed with it. Specifications 538,289 and 545,693 are referred to.
