Title: Improvements in direction indicators for motor road vehicles
IPC: B60Q1/34
Filed: 1924-12-29
Abstract: 246,643. Scott, P., and Bonham, A. Dec. 29, 1924. Road-traffic signals on vehicles.-A direction indicator for road vehicles, comprising a casing 1 having transparent signs 2 on its front and rear faces, is pivoted to a support 5 on the windscreen and is raised into a horizontal signalling position by a Bowden wire 7 connected to an actuating lever 14 pivoted to a support 21. The lever 14 co-operates with a wedge-shaped contact 20 and forms a switch for illuminating an electric lamp in the casing 1, when the casing is raised. The circuit of the lamp is completed through the Bowden wire 7. The casing 1 is held in its signalling position by the engagement of the lever 14 with a notch in the contact 20 under the influence of a spring 25 which allows lateral movement of the lever on its pivot during the passage over the contact 20. The casing has a buffer 29 and a spring clip 27 which engages the supports when the casing occupies its normal position. The casing also has a V-shaped reflector which deflects light from the lamp through the signs 23. The Provisional Specification states that the control lever may co-operate with two channel-shaped contacts.

Title: Dynamic weigher with electronic counter
Inventor: BRADLEY ROBERT ORVILLE
IPC: G01G3/02
Filed: 1953-11-11
Abstract: 725,926. Weighing apparatus. TOLEDO SCALE CO. Nov. 11, 1953, No. 31201/53. Class 143. [Also in Group XL (b)] A lever is acted upon by a load to be weighed and a spring in opposition, and allowed to make one complete oscillation from a position of disequilibrium, electric pulses being generated for each equal increment of movement of the lever, the pulses being. counted electronically to indicate the weight of the load. As shown in Fig. 1, the load is placed on plate 1 on a spider 2 constrained to vertical movement by arms 3, 4 attached by horizontal and vertical leaf-springs 6, 7 to the spider 2 and standard 5; a projection 8 supports a spring 9 anchored to arm 4 to oppose the downward thrust of the load; arc arm 24 on spider 2 is connected by a flexible strip 22 to one end of lever 17 pivoted by horizontal and vertical leaf springs 19, 20; lever 17 carries a slotted shutter 32, Fig. V, which can move between a light source 38 and photoelectric cell 40 to generate pulses. To make a weighing, switch 46, Fig. VI, is closed to start motor 43 which makes a holding circuit for itself over cam-operated contacts 51; cam 50 then closes contacts 52 to produce a zero-setting pulse for the electronic counter 42 and to energize relay 36 to release a catch 31, thus releasing the lever 17, Fig. I, and spider 2 from a position of disequilibrium; during the subsequent movement as spider 2 moves downwardly, the shutter 32 moves to generate pulses which are counted in the electronic counter 42; towards the end of one complete oscillation the cam 50 breaks contacts 52 to release relay 36 so that the catch 31 re-engages lever 17 at the bottom of its swing. In a modification, Fig. VIII (not shown), the spring 9 is arranged to act on the lever 17. In a further modification, Fig. VII, the spider 60 carries the shutter 73 on an arm 74 and is directly acted upon by the stop catch 67. In another modification, Fig. IX, the load is applied to the far end of member 100 against a spring 106 through a tape 110 wound round a shaft 104 carrying arms 113, 127; arm 113 carries a slotted shutter 114 for generating the pulses, and arm 127 carries a stop 128 released when cam 129 rotates clockwise and re-engaged when the cam has made one complete revolution which is timed to coincide with one complete oscillation of arm 127. Subsidiary cams driven from motor 137 make contacts for setting the electronic counter to zero and for stopping the motor 137 at the end of one rotation of cam 129. Adjustments. In Fig. I the anchorages of the spring 19 are adjustable along the arms 8, 4 to accommodate widely differing loads, and the equilibrium position of the spider 2 is adjustable by screw and nut 13 on the anchorage on arm 8. In Fig. IX the effective length of the spring 106 is variable by a collar 111 forming part of the support rod 107, and nuts 112 permit the equilibrium position to be adjusted. Specification 425,229 is referred to.

Patent GB-412105-A (GB)
Title: A process for the preparation of aqueous solutions of hypochlorous acid
IPC: C01B11/04
Filed: 1933-11-09
Abstract: <PICT:0412105/III/1> Aqueous hypochlorous acid is obtained continuously by causing chlorine to react with water in an absorption tower filled with fragments of calcium carbonate and thereafter contacting the resulting solution with fragments of calcium carbonate in order to convert any remaining free chlorine into hypochlorous acid. Water flows from a conduit 3 into an absorption tower 1 filled with fragments of marble.  Chlorine introduced from a cylinder 7 through a dosing plant 8 enters the tower through a conduit 9 and ascends the tower in counter-current to the water.  The resulting solution flows to the bottom of the tower and is dammed up by the liquid seal formed by a bent outlet pipe 4 to remain in contact with the calcium carbonate.  Alternatively, the liquid seal may be omitted, the solution flowing directly from the tower and then passing over further calcium carbonate.  Fresh marble is continously introduced at the top of the tower.  U.S.A. Specification 1,413,153 is referred to.

IPC: F16L27/08
Filed: 1974-07-16
Abstract: 1460386 Transferring liquids; counter-balancing FMC CORP 16 July 1974 [24 Aug 1973] 31367/74 Headings B8E and B8B A tank truck loading terminal comprises three fluid-transferring pipe arms 20, 20a, 20b, for use in transferring fluid to trucks such as that shown as 38, the pipe 20 comprising an inboard arm section 22 which is mounted on a vertical riser 24 for pivotal movement about an axis A in a horizontal plane, an outboard arm section 28 being connected to the arm section 22 by a swivel joint 30 which permits their relative movement about a vertical axis B, the section 28 comprising inner and outer pipe members 40, 42 which are pivotally connected such that the member 42 can rotate about a horizontal axis C, and a coupling assembly 32 for attaching the arm 20 to the truck 38, and which includes a vertical swivel joint 56, is connected by a horizontal swivel joint 34 to the pipe member 42. A counterweight 52 counterbalances the pipe member 42 and coupling assembly 32 about the axis C. The arms 20a, 20b are similar to the arm 20, and due to the pivotability of the pipe members of the three arms about the respective axes B, B<SP>1</SP>, B<SP>11</SP>, and the respective horizontal axes C, the arms may be crossed over one another. In the modification of Fig. 9 (not shown) the pipe member (42) and coupling assembly (32) are counterbalanced by a tension spring (70), and in Fig. 10 (not shown) a fluid ram (76, 80) is used for this purpose, while in the modification of Figs. 12 and 13 (not shown) a compression spring assembly (90) is utilized. A gear assembly (104) is described in relation to Figs. 14-16 (not shown) to provide the counterbalancing, and it comprises a housing (106) secured by a bracket (108) to the vertical component (48) of the pipe member (40), a ring gear (110) surrounding and secured to the pipe member (42), and a pinion gear (112) in mesh with the ring gear (110), the gear (112) being connected to an external crank handle (116), rotation of the latter causing rotation of the gears (112, 110) thereby pivoting the pipe member (42) with respect to the housing (106).

Abstract: 1,240,322. Feeding sheets. INTERNATIONAL BUSINESS MACHINES CORP. 1 July, 1968 [14 Aug., 1967], No. 31425/68. Heading B8R. [Also in Division F2] A body, e.g. a document, moving along a feed path 12 to a work station 17 is arrested by a brake mechanism 20 comprising a brake mass 35 extending at an acute angle across the path and adapted when struck by the body to absorb the kinetic energy in the body by substantially vertical movement. The brake 35 may be positioned by a leaf-spring 36 such that it rests in contact with path 12. In an alternative form, Fig. 2, the brake mass may comprise a freely mounted roller 46 resting in contact with feed bed 43 and whose vertical movement is limited by member 50. In a further form (Fig. 4, not shown), a vertically movable roller is mounted beneath a lower feed surface and protrudes therefrom to abut an upper feed surface between which surfaces the document is fed. The roller is held in its raised position by a yieldable spring. The brake may arrest documents, being fed from stack 10 by feed rollers 13 and 14, before they reach work station (e.g. punch) 17. The arrested sheets are moved forward by actuation of roller 22 to press against driven roller 23, thus pushing the sheets beneath the brake. The sheets are delivered by rollers 31 to stacker 33.

Title: Improvements in or relating to radar systems
IPC: G01S13/87
Filed: 1953-11-13
Abstract: 729,897. Pulse radar; pulse frequencydivider circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 13, 1953 [Nov. 17, 1952], No. 31526/53. Classes 40. (6) and 40 (7). Relates to a system of adjacent pulse radars 2 ... 5 operating at recurrence frequencies, e.g. 1200, 600, 600 and 300 c/s, which are subharmonics of a master frequency f=2400 c/s., synchronizing pulses Vs of recurrence frequency f being applied to each radar from a common pulse generator 6 via frequency dividers 8 ... 11. According to the present invention mutual interference between the radars is reduced by deriving further synchronizing pulses Vk of recurrence frequency f/n= 300 c/s., equal to the lowest radar recurrence frequency, from the pulse generator 6 by a further frequency divider 12 and mixing the two sets of synchronizing pulses at 15, each frequency divider 8.... 11 being such that a division cycle is initiated by a synchronizing pulse Vs adjacent to a synchronizing pulse Vk, the resultant trigger pulses for radars 2, 3, 4 and 5 being as shown in Fig. 2b, c, d and e respectively. The system also includes a radar 1 triggered directly by the synchronizing pulses Vs. As shown, the synchronizing pulses Vs are negative and each positive synchronizing pulse Vk is delayed relative to its corresponding Vs pulse by means of delay device 13. Each frequency divider comprises a multivibrator 24, 25, Fig. 3, V25 being normally conductive and V24 cut off. V24 is triggered by a negative Vs pulse which is selected by diode 33, inverted by V36 and applied to the grid of V24 via diode 37 and C27, the circuit constants being such that the multivibrator reverses before the next Vs pulse and the negative charge on C27 prevents retriggering of V24 until a predetermined number of Vs pulses, e.g. 2, 4 or 8, have been received. The positive Vk pulses are selected, inverted and amplified by V38 and applied via C30 to the grid of V25. If V24 has been triggered by a Vs pulse 22 immediately preceding a Vk pulse, then V25 is cut off and the Vk pulse is ineffective, but if V24 has been triggered by an earlier Vs pulse, V25 will be conductive and will therefore be cut off by the Vk pulse, thereby triggering V24. Accordingly in the steady state the Vs pulse 22 initiates a division cycle in each divider 8 ... 11. Alternatively, the pulses Vs and Vk may be coincident and of like polarity and may be separated by an integrator or amplitude discriminator and each frequency divider may comprise a blocking oscillator, the synchronizing pulses Vk being applied to the grid thereof.

Abstract: 971,501. Reactors. BRISTOL AEROJET Ltd. Dec. 14,1960 [Sept. 16,1959], No.31549/59. Heading G6C. A strut for supporting fuel elements in a vertical channel in a reactor includes a valve which reduces the flow of coolant up the channel when fuel elements are lifted off the strut. The strut shown has a housing 10 joined by a leg 12 to a spigot 11 which rests in a spider fixed in the channel. A column of fuel elements rests on a cap 39 forming part of a shaft 40; a flange on the shaft rests in a cup 45 supported by a coil spring inside housing 10. The housing carries spiral vanes 35; a rotatable sleeve 32 carries vanes 33. When the vanes are aligned they form aerofoils as shown; rotation of sleeve 32 can close the channel apart from a small space outside shroud rings 34, 36. Removal of fuel elements from the column lets the spring lift the shaft so that balls 50 which engage helical grooves in the sleeve 32 cause the latter to rotate to reduce the coolant flow; when the cup reaches a stop 47 the channel is fully closed. The strut itself can be lifted by the cap; this rotates the shaft further and restores coolant flow, and then causes a rod 41 to release latches holding the spigot in the spider. The leg 12 is held in the housing 10 by a bush with a neck 19a which breaks when the cap recieves a sharp blow; cutters 27 cut the housing to absorb the impact.

Abstract: 748,387. Locking-nuts. BESSOM CORPORATION, E. A. Nov. 13, 1953 [Dec. 10, 1952], No. 31605/53. Class 89 (1). A lock-nut comprises an annular base-flange 10, Fig. 4, and a barrel 12, Fig. 5, integral therewith, the barrel being formed of a number, e.g. two, of radially-expansible arcuate segments 14 threaded internally and interconnected by U-shaped loops 16. The segments are closed inwardly of the normal pitch-circle of the thread progressively along the length of the barrel to a maximum at its free end. The maximum inward closure on a cross-section through the barrel lies at points mid-way between adjacent loops, and the points of juncture between the segments and loops are located outside the pitch circle. This result is obtained by altering the radius of curvature of the segments between dies, so that the segments coincide with the pitch circle near the said points of juncture.
