Title: Stabiliser for wheeled vehicles on a transporter
Inventor: MASON PETER
IPC: B61D45/00
Filed: 1959-06-12
Abstract: 954,290. Securing vehicles on carrier vehicles. B. H. COLQUHOUN, F. D. THOMAS, I. M. E. AITKEN, W. J. LLEWELLYN, P. MASON, and A. U. SHIACH, [trading as BRIAN COLQUHOUN & PARTNERS], and MITCHELL ENGINEERING Ltd. June 9, 1960 [June 12, 1959], No. 20289/59. Heading B8E. [Also in Division B7] To prevent movement of a vehicle along a transporter vehicle 1, Fig. 2, two pairs of members 10, 11 are urged away from each other against the wheels 20a, 20b of the vehicle. The vehicle is moved on to a rail-truck 1 and astride a locking unit 2 which is moved on wheels 3 by a ram 4 until it is approximately mid-way between the axles of the vehicle. Rams 5 are next expanded to move shafts 8 on which are mounted plates 10, 11 towards the wheels. The plates 10 are rotatably mounted, and plates 11 are fixed to the shafts 8. Consequently, when the plates 10 abut the wheels the shafts 8 are rotated by arms 7 to raise plates 11 to the position shown in association with wheel 20a. Several sets of locking members may be provided on a truck and if necessary adjacent ends of two sets of locking members may co-operate to secure a wheel. In a second embodiment, Fig. 8, longitudinal frame members 31, 31a of a rail truck are connected by spaced parallel transverse members 32. Between each pair of members 32 is mounted for vertical movement a pair of locking members 33, sufficiently close together that several are located within a distance equal to the diameter of a vehicle wheel. With the members 33 in the down position one or more vehicles are driven on to the truck. Hydraulic rams 41 are now expanded to raise the members 33 through links 39, 36. All the members 33 not restrained by vehicle wheels are thus raised and held in position by ratchet and pawl mechanism 44, 45. In addition the links 36 pass through their tow-dead-centre positions and an hydraulic lock is provided in the rams, thus the system always fails safe. The outer ends of members 33 are raised higher than their inner ends to provide greater stability for heavier wider-tracked vehicles. To lower the locking members the ratchet bars 44 are raised and released by cams 46 on shafts 47 and therams 41 are contracted. The locking members may be restricted to zones which coincide with the wheels of vehicles to be carried. In both the embodiments electrical, mechanical, pneumatic or vacuum operating means may be used. Specification 954,289 is referred to.
Patent GB-506310-A (GB)
Title: Combination lock
IPC: E05B37/02
Filed: 1938-07-09
Abstract: 506,310. Latches; permutation locks. DEWE. July 9, 1938, No. 20347. Convention date, May 13, 1938. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 3, 1939] [Class 44] In a permutation-controlled latch having a locking member co-operating with permutation discs and with the bolt, the locking member 14, Fig. 1, has a nose 46 capable of being moved clear of the path of the bolt 42, after movement of the locking member with the combination formed, to permit free operation as a latch in spite of a subsequent disengagement of the locking member from the permutation discs 56 and scattering of the combination. The nose is slotted at 45<1> and mounted on the locking member by a flattened spindle 44 carrying a hand lever 44<1>. After forming the combination the lever 44<1> is pushed to slide a part 13 of the locking member into the notches 13<1> of the discs 56. This movement withdraws the nose from the bolt 42 and continued pressure on the lever turns the spindle 44 and with it the nose 46. If the locking member is allowed to return to its former position with the nose 46 kept inclined, and the combination scattered, the parts take up the position shown in Fig. 3. The bolt 42 can then be operated freely by a knob 51. To block the bolt, the nose is turned by the lever 44<1> until it snaps behind the shoulder of the bolt, the slotted mounting of the nose on the spindle 44 enabling this to be effected without the necessity of forming the combination. The permutation discs 56 have individual setting knobs 56<1>, Fig. 4, and are nested one within another, the part 13 of the locking member 14 being stepped to enter all the notches 13<1> simultaneously.

Abstract: 1,139,573. Continuous winding. JOHNSON, MATTHEY & CO. Ltd. 5 July, 1966 [17 May, 1965], No. 20684/65. Heading D1J. Wire (or thread) issuing continuously from a fabrication or treatment station 10 is automatically wound onto a plurality of spools e.g. 16, 18, by winding the wire onto a first spool, 18, then causing the wire to be continued to be wound on one or more spools, 16, in succession while maintaining the path of the running wire unaltered. The wire on the first and successive spools is automatically severed from the running wire on the respective succeeding spool. As shown wire is wound by passing the wire 11 through an apertured guide 14 on each of the spools, e.g. 16, that are to be wound up after the first spool 18 is full of wire. When spool 18 is full, spool 16 is rotated to wind - the wire about it and sever the partion of wire between the full and adjacent empty spool. Figs. 3 and 4 (not shown) illustrate the wire passing through 4 and 2 spools respectively before being wound onto spool 18 the apertured guide 14 may be a hole or a radially extending slot (20), see Fig. 2 (not shown). In the latter case the slot should be in such a direction that the wire does not move out of it.

Abstract: 1365823 Measuring volume of flowing liquid LKB-PRODUKTER AB 3 May 1972 [5 May 1971] 20690/72 Heading G4H In measuring the volume of a liquid flowing past a point in a capillary tube by dividing the flow into portions of equal known volume by injecting bubbles and counting the bubbles at R1 as they pass the point, a new bubble being injected each time a bubble is detected, the resolution is increased by controlling the flow by a pump or valve P using a control signal I from which is derived, at SF, pulses for interpolating the gaps between the bubbles. The pulse frequency is automatically adjusted so that 100 pulses are counted at R2 in the interval between consecutive bubbles, the counter R2 being automatically zeroed each time a bubble is detected. Automatic titration may be monitored, a photo-electric detector causing the control signal to diminish and cease as the endpoint is approached and reached. Alternatively predetermined volumes of liquid may be dispensed, the control signal terminating when a predetermined count is reached.

Abstract: 1300560 Frangible diaphragm closures GRAVINER (COLNBROOK) Ltd 20 April 1970 [23 April 1969] 20706/69 Addition to 1136725 Heading A5A In the fluid container of Specification No. 1136725 the operating member for puncturing the diaphragm is freely rotatable if pressure is not being exerted on the diaphragm by gas in the container but resists rotation if gas pressure is present, the same operating member, when struck, is also slidable in an aperture in a member fixed to the container the relative shapes of the operating member and the aperture being such as to wedge the former in the latter when the diaphragm is punctured. In Fig. 1 container 11 for liquid or dry powder under pressure has outlet 10 sealed by copper diaphragm 12 which is sandwiched between outlet rim 13 and externally screwthreaded ring 14 engaging container collar 15. Ring 14 clamps 12, forming a liquid tight seal between 12 and 13. Assembly 17 includes discharge nozzle 16 and is screwed at 17a to collar 15 with the lower end surface of 15 engaging flange 17b; 17 also houses plunger 18 with head 18a against which diaphragm 12 is urged by the container pressure. Downward movement of 18 is prevented by engagement of flange 18b with an inner lower surface of 17. Gripping head 18c is rotatable only if the container gas pressure has dropped and rotation is thus indicative of a fault. If, however, container 11 is fully operative and is to be discharged a blow on plunger 18 punctures diaphragm 12. Tapering stem 18d of head 18c wedges in the lower assembly opening with head 18a clear of outlet 10 for free passage of the container contents to nozzle 16. In Fig. 1 the plunger head 18a has a concave face and in Fig. 2 head 28a a convex face.
