Patent GB-310831-A (GB)
Title: Improvements in or relating to weighing devices
IPC: G01G23/18
Filed: 1928-02-01
Abstract: 310,831. Pollak, J. E., (Seitz-Werke Ges.). Feb. 1,1928. Printed records, apparatus for giving. - A weighing machine has a platform which, during the first part of its descent., sets an element, such as a weight, to reset the apparatus after a ticket stamping and issuing mechanism has been released by a coin. When a weight is applied to the platform 50, the beam 51 is depressed until the lever 63 rests on the fixed stop 64. The lever 63, tilting about the pivot 62, raises the rod 1 to cause a hook 3 thereon to lift the lever 6 and raise the weight 7 until retained by the engagement of the hook on the arm 9 with the stop 8. Further raising of the rod 1 causes the cam 13 to engage the fixed pivot 15 of the arm 9, so removing the hook 3 from the path of the stop 4. When the lever 63 is resting on the fixed stop 64, the beam 51 is tilted about the knife edge 60 to cause a rod 52 to rotate the type wheel 38 to bring the correct reading under the ticket 33. A coin placed in the slot 16 then tilts the bar 18 to cause a cam 20 to tilt a bell crank lever 23, pivoted at 22, out of the path of the lever 25, which is then rotated about its pivot 24 by a weight 26. The lever 25 engages a rod 28 at 27, and on rotating, lifts this rod to depress the hammer 36, so pressing the ticket 33 on the type wheel, and moving the stop 32 from under the stack of tickets, which then falls down behind it. Raising the rod 28 also causes a stop 39 thereon to tilt the lever 9, 11 about its pivot 15, so freeing the arm 6, which is then pulled down by the weight 7, engaging a stop 40 on the rod 28 to re-set it and cause the stop 32 to push a ticket into position for the next weighing. The rod 28, in descending, re-sets the lever 25 and the stop-lever 23 drops back below it under the influence of a spring or counterweight. The lever 63 and rod 1 are returned to their original position by a spring 65 and an oil damping device 66 prevents backward movement. The piyot 58 of the transmission gear 56, 57 may be fixed as in Fig. 1, or on the lever 63 as in Fig. 6.

Abstract: 470,004. Cathode-ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and LEVIN, N. Feb. 3, 1936, No. 3269. [Class 39 (i)] A cathode-ray tube for use in television systems has a cathode 1, an apertured control electrode 2, and a first anode 3, the dimensions of the cathode being large compared with the size of the aperture in the control electrode, the beam being focused upon the aperture by a succeeding electron assembly which is so arranged as not to be effected by varying voltages applied to the control electrode, which is placed at a distance of approximately 0À005 inch from the cathode, the first anode being at a distance of 0À02-0À03 inch from the control electrode ; the electron assembly succeeding the first anode may give an electron accelerating or decelerating region. A long cylindrical electrode 4 with a small central aperture in its end faces is arranged between the anode 3 and another apertured anode 5. The potential of the anode 3 may be 1000 volts, the electrode 4, zero and the anode 5, 3000 volts. The rays are projected on a screen 6, which may be also the final anode. The arrangement is such that the scanning image on the screen of the control-electrode aperture changes in intensity but not in size or shape, or does not exceed a certain size. In a modification, a preliminary focus of the aperture in the control electrode is formed in the aperture in the electrode 4 nearest to the anode 5, and diverging rays are stopped by the anode 5. In another tube, Fig. 4, two apertured anodes 3, 3a are arranged between the control electrode 2 and the cylindrical electrode 4, and the anode 5 consists of an apertured plate in a cylinder 5a which may be a screening deposit of metal on the envelope. The anodes 3, 3a form an image of the control-electrode aperture on the first aperture 4a of the electrode 4, and the second aperture 4b in that electrode, with the anode 5, re-forms the image on a screen, not shown.
Patent GB-573525-A (GB)
Title: Improvements in or relating to the production of gas expanded rubber materials
Filed: 1940-02-21
Abstract: In making gas-expanded rubber material using ultra fast or semi-ultra fast accelerators, the mixing of the composition takes place in the absence of either the sulphur, or the accelerator and the missing ingredient is added just prior to calendering or, where a moulded article is to be produced, just prior to the moulding stage.  After calendering or moulding the mass is allowed to become sufficiently vulcanized to retain the gas when impregnated therewith.  The gassing may be produced by adding gas producing materials such as an acid or a carbonate.  The process may be carried out in two or three stages as described in Specifications 358,967 and 506,077.

Title: Improvements relating to locks
IPC: B29C43/08
Filed: 1951-02-12
Abstract: 693,316. Locks. LINES, A. Feb. 5, 1952 [Feb. 12, 1951 ], No. 3335/51. Class 44 In a mortice key latch having a latch bolt retractable by the movement of a handle, a removable key may be turned to cause disengagement of the latch bolt from the handle by displacement of the inner extension of the latch bolt to render the bolt no longer retractable by the movement of the handle. In the arrangement shown, a recess 20 in a slot at the inner end of a bolt lath of a bolt 2 permits the bolt 2 to rock about a point 18, when a pin 4 in the lath is then clear of a hub follower 3 which normally engages the pin to withdraw the bolt. A key follower 8 rotatably mounted on a key socket 6, follows rotary movement of a cam 7 by means of a stud engaging a groove 9 in the cam. If the key is inserted and turned anticlockwise to unlock or retract the bolt from the position shown in Fig. 2 the cam 7 engages a projection 14 on a talon plate 11 to effect engagement of a talon 13 in slots 17 of vertically slidable lock plates and disengagement of a catch 12 on the talon plate with the bolt lath. The follower 8 then engages a lug 10 on the lath to retract the bolt. Clockwise rotation of the key to lock the bolt, effects registry of the slots 17 which is followed by movement of the talon plate by the engagement of cam 7 with projection 14 and movement of the talon 13 into the slots and disengagement of catch 12 rearwardly of the bolt lath. The follower 8 then engages lug 10 to rock the bolt about point 18 and a slight further movement of the follower allows the talon plate to move into position in which the bolt lath is supported by the catch 12. The key may be made to operate from either side of the latch. The latch may be made to operate with two different keys, by providing separate sets of slots in the lock plates, as disclosed in Specification 666,618.

Abstract: 1,261,550. Electromagnetic brakes. SOC. "POTAIN". 22 Jan., 1969 [23 Jan., 1968], No. 3524/69. Heading F2E.  A control circuit to provide gradual release and application of an eddy-current brake 3, 4 to the motor shaft 1 of a crane effects a required brake actuation in a time equal to that required to discharge or charge a capacitor, 14. In use, to initiate swinging of a tower crane, a contactor 7 or 8 is closed by a respective switch 5, 6 to swing the crane in a required direction which closure connects the point 10 to supply line 9 to discharge the capacitor 14 thus turning off transistors 17 and 20 and releasing the brake due to reduction of current in the coil 4, the reduction of current following a similar law to that governing the discharge of the capacitor. When the motor is required to stop the switch is opened so that the capacitor charges through resistors 11, 16 causing current to flow through the coil to re-apply the eddy-current brake. A locking brake applied to a turning part is provided. In an alternative embodiment, Fig. 2, (not shown), a rheostat (25) is included in series with the capacitor to provide manual adjustment of charging time, the remainder of the circuit being as above.
