Title: Door handle assemblies for operating the spring bolts of latches
Inventor: ROGERS ARTHUR LAURENCE
IPC: E05B3/06
Filed: 1963-10-30
Abstract: 1,085,059. Door handle assembly. ASH & ROGERS Ltd. Oct. 5, 1964 [Oct. 30, 1963], No. 42771/63. Heading E2A. A door handle assembly comprises a lever handle 14 turnably mounted in a beating hole in a door plate 10, a stop plate 25 which is carried by and turns with the shank 15 of the lever handle, fixed abutments on the door plate 10 and on opposite sides of the handle shank axis with which the stop plate co-operates to determine the range of angular movement of the lever handle, and a handle-loading coil spring 30 which operates between an eccentrically disposed anchorage which turns with the handle shank and one or other of two stationary anchorages, on opposite sides of the handle shank axis, according to the "hand" of the handle. The stationary anchorages for the spring 30 are provided either on a back plate 21, as shown, having a bearing hole which registers with that in the door plate, or on the rear of the door plate, a bearing spigot portion 16 of the shank 15 having the usual square section axial recess 17 to receive a spindle to be operated, is formed immediately rearwardly of the door plate, or back plate, if present, with a transaxial slot 18 which crosses the recess 17, the stop plate 25 has an integral tongue 26 which fits into and extends through the slot 18 so as to retain the shank 15 and back plate, if present, against removal from the door plate, and the spring anchorage 31 which moves with the handle shank is provided in the stop plate and is so disposed that the spring tends to maintain the tongue against withdrawal from the slot 18. As described the stop plate is "L" shaped and has angled end edges 28, 29 adapted to engage a side flange 11 on the door plate to limit the turning movement of the handle in each direction, and has a square through hole to correspond and register with the recess 17. The stationary anchorages for the spring are hook portions 22 on the back plate 21, whose side edges 24 engage with the flange 11 to prevent its rotation. When the handle is to have the other "hand" from that shown the spring is disconnected the stop plate removed, the handle rotated through 180‹, the stop plate replaced after being reversed side to side and the spring connected to the other hook portion 22.

Abstract: 1,267,892. Moulding bricks. STEENFABRIEKEN V/H TERWINDT & ARNTZ. N.V. 8 Sept., 1970 [8 Sept., 1969], No. 42848/70. Heading B5A. In a method of brick moulding, a slug of clay 10 of a length and width slightly smaller than the finished brick is placed in a mould 11 and spaced from its side walls and is then subjected to an impact force by a die 16 having a convex face which contacts that part of the slug extending above the mould top whereby the slug is expanded against the side walls. Moulds are fed in turn below the die having been previously loaded with a clay slug, and the die may be dropped from an adjustable height and/or it may be acted upon by adjustable spring means, or by a piston and cylinder assembly. The lower surface of the die may be of rubber. A tap 18 may carry more than one die enabling multiple lines of moulds to be used.

Abstract: 948,078. Rotary pumps and motors. HARTMANN MANUFACTURING CO. Dec. 15, 1960, No. 43190/60. Heading F1F. A rotary pump or motor comprises a rotor 14, Fig. 1, having integral shaft bearing portions 16, 17 and diametrically opposite vanes 33, Fig. 2, engageable with cut-outs 32 in roller abutments 31. Interchangeable inlet and outlet ports 41, 42 open into annular rotor recesses 43, 54 respectively connected by slanting passages 44, 46 and 52, 53 with rotor recesses 47, 48 and 49, 51 on opposite sides of the vanes so that the rotor is in substantial fluid balance. Surfaces 82 on the radial extremities of the vanes are interconnected by a diametrical passage 81 to further balance the rotor. Recesses 58, 59, Fig. 4, associated with each roller abutment 31 are spaced on either side of and each equal to half the width of the working chamber 29. These recesses are connected by passages 64, 65, 66 and passages 61, 62, 63 to the working chamber 29 and similarly a recess 67, Fig. 6, separated from the recess 58 and a similar recess 68 (not shown) separated from the recess 59 are connected by passages 69, 70, 71 and 72, 73, 74 respectively to the chamber 29. Recesses 94, 96 diametrically opposite the recesses 58, 67 and 59, (68 not shown) and diametrically opposite a recess 91 adjacent the roller abutment and in alignment with the working chamber are also interconnected by passages. Thus the roller abutments 31 in all positions are also fluid-pressure balanced. Seepage from the working chamber 29 along the shaft bearing portions 16, 17 and passages 88, 89 in these portions permit lubrication of the shaft bearing portions.

Title: Improvements in electronic devices
Inventor: AMBROSINO FRANCESCO
IPC: H03K21/40
Filed: 1960-12-20
Abstract: 897,400. Counters. STANDARD TELEPHONES & CABLES Ltd. Dec. 20, 1960, No. 43688/60. Class 106 (1). In an electronic ring counter, if more than the correct number of devices constituting the counter are simultaneously in the operated state a fault detector operates, and means are further provided to test the fault detector. In the example described, only one of the toggles A-N should be in the "1 " state at any time. The conditioning gates GA-GN are shown, but not the usual strobe gates. If two toggles should be operated simultaneously a gate G1 opens to operate toggle Y, and provided the test circuit is not being used, gates G6, G7 open to operate an alarm. The fault detector is tested while the counter is otherwise idle by applying a P1 pulse to two adjacent toggles. The counter then runs with a pair of adjacent toggles operative, AB, BC, CD, &c. The pulse P1 is followed immediately by a pulse P2 which operates toggle X so that both X and Y are operated whereby gate G6 is closed to prevent operation of the alarm. X resets Y at alternate stages through gate G3. If X fails to reset Y at these stages one of gates G9 operates the alarm. In a modification, Fig. 3, a ring counter which normally runs at a low speed is run at a higher speed for fault detection. Advance is controlled by toggle S which automatically resets itself. The speed of the counter therefore depends on the frequency of the input to S.

Reflux to a distillation apparatus, wherein vapours rise up chamber 1 and through apertures 4 in hood 3 to a liquid/vapour separator 2 and a condenser (not shown), is controlled by an external divider valve 5 comprising an intake chamber 8 which receives the condensate through conduit 11, a reflux chamber 6 connected by conduit 12 to the vapour chamber 1, an off-take chamber 7 connected to product discharge conduit 13, and valve-members 9, 10 which operate to permit condensate to pass from the intake chamber 8 either to the reflux chamber 6 or to the off-take chamber 7. Valve-members 9, 10 cooperate with valveseats 22, 23 and are urged against the seats by springs 24, 25. The valve-members are movable axially against the action of the springs by solenoids 26, 27 operable by a timing device (not shown). As shown in Fig. 5 the reflux chamber 6 is open to intake chamber 8, and the off-take chamber 7 is closed to the intake chamber 8. While the divider 5 remains in this condition the condensate passing through conduit 11 flows through chamber 6 and conduit 12 and is delivered as reflux into vapour chamber 1. When the positions of valve-members 9, 10 are reversed, all the condensate entering chamber 8 flows out through chamber 7 and conduit 13. Conduit 12 is detachably connected to chamber 1, and conduit 11 is detachably connected to separator 2 so that the divider 5 can be detached as a unit from the distillation apparatus.
