Abstract: 1,075,423. Fluid-pressure apparatus. PLESSEY-UK Ltd. May 1, 1964 [May 4, 1963], No. 13440/63. Heading F1P. Locking of a fluid actuated piston (1) Fig. 1 (not shown) at either end of a cylinder (5) is effected by one or other of two sets of spring claws (14) carried by said cylinder ends engaging shoulders (13) formed in piston recesses (12) and unlocking at the start of a stroke is effected by the action of fluid-pressure on an auxiliary piston (7) which is axially displaced relative to the main piston and thereby allows a cam surface (17) to contract the claws (14); the so displaced auxiliary piston then being in such a position as to allow locking of the main piston when it reaches the end of its stroke.
Patent GB-135146-A (GB)
IPC: H01R4/10
Abstract: 135,146. Jordan, J. W. June 23, 1919. Wire terminals.-An end-piece on a lead to facilitate connexion to a binding-post consists of a circular metal blank with a central hole and two segmental slots 12, 13. The metal is bent down at the slotted parts, as shown, so as to leave a raised central portion 14. In the case of stranded conductors, the strands are threaded through the two slots and divided so as to lie in equal numbers on the two sides of the central aperture. In the case of a single conductor, the conductor is passed through the slots, the end turned back on itself and passed back through the slots so as to leave the aperture clear. When the wires are threaded, the bent-down portions of the blank may be bent back somewhat so as to retain the wires. The nut on the binding-post tends further to flatten out the blank which acts as a spring washer and is securely held, the wires being further clamped within the slots. The blank may be furnished with a lug which is bent round the insulation of the conductor and serves as a support.

Moulding walls in situ.-Walls are cast in situ between opposed tiers of shuttering, at least three on each side, arranged so that the lowest tier may be swung to a new position on the top tier, allowing sufficient time for the lowest portion of concrete to set before removing the lowest shutters, even in walls of small perimeter. The shutters are provided with aligned angle-bars 2A having upper lugs 12A for engagement with upper cross-ties 39A and lower adjustable clips 10A for engagement with slots in lower crossties. The flanges of the angles are slotted and carry sliding bolts 7A, and the top edges of the angles are notched to receive bolts 5A. Radius rods 3A are provided of about the same length as the angle-bars and other shorter radius rods 4A are also provided, the rods being connected as shown in Fig. 2, the lower 3A connecting the bolt 7A on the lowest shutter with a bolt 6A on a shorter rod 4B, which is secured to the bolt 5B resting on the top of the second tier. the second radius rod 3B connecting the bolts 7B and 7C on the other shutters. After casting to the depth of the three tiers of shutters, the clip 10A of the lowest shutter is disengaged from the cross-tie, and the angle 2A slid downwards to disengage the lug 12A, the bottom tier being then turned on the radius rods about the bolts 5B and on the bolts 7A about its own axis to a new position superimposed upon the tier 2C. The rods are then reconnected, as shown in Fig. 4, to agree with the connections shown in Fig. 2 for a further raising, after the next course has been cast. The distance-pieces may be flat slats or formed as shown in Fig. 6, having a main portion with upturned ends to receive the detachable and adjustable perforated ends 38. Four-tier shuttering may be employed as shown in Fig. 8, the radius rods 3 used in this case being all approximately of the same length and equal to the width of the shutters. The lowest tier is swung up about the pivot pins 15 and rotated on its axis to its new position, and the rods are reconnected so that, after the next course is cast, the tier 1B may be raised. The walls may be recessed or provided with projections by the provision of perforated adjusting rods 30 to be used in conjunction with the radius rods, Fig. 13. The top tiers of shutters may be supported in inclined position by rods 47 to form a shoot for the concrete.

Abstract: 1462250 Dispensing liquids H TATSUNO 29 March 1974 [24 Aug 1973 (4)] 14053/74 Heading A4T [Also in Divisions B2 and F2] A pistol-type nozzle valve e.g. for dispensing petrol from a delivery pipe 20 on an overhead reel (61), Fig. 2 (not shown), comprises a spout 2, a barrel frame 3 and a handle grip 4, an inlet 9 on the face of the barrel frame 3 being provided for connection to the pipe 20. For delivery, a trigger 21 is pulled back, acting on a push-rod 22 locked to a pilot valve rod 17a by pins 23 borne in slots (28b) of a generally U-shaped member 28, Fig. 7 (not shown), and engaging in a notch 17c of the rod 17a and a notch 22a of the rod 22. As the rods 17a, 22 are pushed back against a spring 26 a bolt head 18a is initially pulled into a counterbore in a main valve 16, and then the valve 16 is disengaged from a seat 12a on a valve seat member 12, allowing petrol to be dispensed through a spring-loaded non-return valve 14. Automatic cut-off: During dispensing, air is drawn into the region of the valve 14 through passages 12c, 36, 10a and a pipe 6 until the end 6a of the pipe 6 becomes submerged, whereupon suction is exerted through ducts 34, 35 leading from the passage 36 to a chamber 29 above a diaphragm 32. Reduced pressure in the chamber 29 results in atmospheric pressure in a lower chamber 30 raising the diaphragm 32, and the member 28, to which it is fixed, is raised, causing the pins 23 to leave the notch 22a, though remaining within the notch 17c. The connection between the rods 17a, 22 thus being released, the main valve 16 is moved to the closed position by the spring 26 to terminate dispensing. On releasing the trigger 21, e.g. from engagement with a spring- loaded retaining member 46, a spring 25 moves the rod 22 relative to the rod 17a to enable the pins 23 to re-enter the notch 22a.
