Title: Process for the production of gasketed container closures
Inventor: CERESA RAYMOND JOHN
IPC: C08L23/00
Filed: 1964-10-28
Abstract: 1,112,023. Container closures. W. R. GRACE & CO. 30 April, 1965 [28 Oct., 1964], No. 44035/64. Heading B8T. [Also in Division B5] In a process for the production of gasketed container closures, a pre-formed insert of a solid thermoplastic resilient material is introduced into a container closure which is warmed sufficiently to cause adhesion of the insert to the closure, and moulding the insert under pressure to the desired shape with a coldmoulding member, if necessary after further heating the closure. The resilient material used may be that disclosed in Specifications 1,112,025, 1,112,024 or 1,092,161; the material may include a blowing agent to provide a cellular gasket. A crown closure shell 11, to which a disc of solid thermoplastic resilient material has been centrally applied, is heated and fed to a moulding station where it is placed in a recessed holder 20 and moulded by a member 22 having pipes 24, 25 for a cooling fluid.

Title: Improvements in arresting gear for movable bodies
IPC: B64F1/02
Filed: 1965-10-20
Abstract: 1,059,756. Aircraft arresting gear. SOC. D'EXPLOITATION DES MATERIELS HISPANO-SUIZA. Oct. 20, 1965 [Nov. 12, 1964], No. 44446/65. Heading B7G. [Also in Division F2] Aircraft arresting gear comprises a barrier (1) and connecting links (e.g. straps) extending from the barrier to a common brake (3) (Fig. 1, not shown) or to individual brakes (3a), (3b): (Figs. 2-4, not shown), and the brakes are automatically controlled to give a constant deceleration using all the stopping distance available regardless of the weight and speed of the arrested aircraft. The speed Vo of the aircraft is determined by measuring the time interval between its crossing two pneumatic detectors (12), (13) and knowing the available distance d. The minimum allowable deceleration=Vo<SP>2</SP>/2d is computed by a multiplier (15) and the instantaneous desired speed V=Vo - γdt is derived from an integrator (16). This is again integrated (17) to give the distance travelled and from this distance the instantaneous speed V and the geometry of the barrier and cables, the corresponding desired speed Uc of the cables through the brake or brakes is derived. This is compared by a comparator (8) with the actual speed, measured by a tachometer (21) (Fig. 1, not shown) on a wheel (20) over which a strap passes, and the resultant signal fed to a servo-valve (4) controlling the pressure in the hydraulic brake (3). Where there are two brakes, one to each strap, the speed of each strap may be monitored, and used to control separate servo-valves (Fig. 2, not shown) or the mean value of cable speed used to control a single valve controlling both brakes (Fig. 3, not shown) or the speed of only one cable may be monitored and used to control a single valve controlling both brakes. The barrier is raised to its operative position by a lifting mechanism operated by a hook on the aircraft engaging a cable extending across the runway (Figs. 5 and 6, not shown).

Title: Timer for a camera
IPC: G03B9/58
Filed: 1971-09-27
Abstract: 1361428 Delayed shutter actuation NIPPON KOGAKU KK 27 Sept 1971 [30 Sept 1970] 44914/71 Heading G2A [ Also in Division H3] An electronic timing circuit for a camera includes a pulse generating circuit which consists of two similar timing sections T1-T7, T11-T16 each producing an output a given time after receiving an input, the outputs being used to trigger the start of the opposite timer circuit and also being combined in an AND gate T7, T8, T10 to produce at T9 the desired output timing signal. The circuit permits repetitive, timedelayed or time-limited photography with cine or motor-driven still cameras. Starting with the switches SW1 to SW4 set as shown in Fig. 2, closure of SW1 connects the battery to the normally conductive T2, and C1 starts to charge through R1 at (t 0 ) Fig. 3 (not shown). When C1 voltage is sufficient to turn on T3-T4 (t 1 ), T5 is also turned on and T7, T6 latch T5 in its on state. The emitter of T8 thus goes high enough relative to the collector of the normally off T10 for T8 to conduct and turn on T9 to start the first output pulse (d). Simultaneously, the fall at T5 collector turns on T14 to start the second timing section, in which C2 is charged through R10. After a further time period (t 1 -t 2 ) T15-T16 go on, and so therefore do T11, 12, 13. When T10 goes on, T8 turns off and T9 ceases to deliver the output pulse. Also, T12 collector turns on T1, turning off T2 and so removing the current supply to T3-T8 which timer circuit therefore resets to its original non-conductive condition, at the same  time turning off T14 to remove the current supply from the second timer circuit T11-T16 which therefore also resets (t 2 -t 4 ). T1 now goes off again and T2 supplies current to R1, C1 for a new cycle to begin, a train of operating pulses thus being produced. In a second operating mode SW4 is switched to C3, so that when SW1 is closed to initiate operation, T5 immediately turns on (t 1 ), and a pulse is produced by T9, operation thereafter being exactly as described, so that a similar pulse train is produced but with the first pulse starting when SW1 closes instead of after a delay. Two other modes corresponding respectively to the above two positions of SW4 cause similar operation of the circuit, but to produce only one output pulse (either delayed or not), by virtue of closure of switch SW3 which prevents the first timer T3-T7 from being reset by T2 turning off. A fifth mode, wherein SW2 is open, and SW4 is connected to C4, produces a delayed rise in T9 output voltage as in the first and third modes, but no operation of the second timer T11-T16, and therefore the output of T9 remains high.

A fluid-operated press 1 comprising fixed and movable platens 3, 5 and a double-acting cylinder 29, is suspended from a carrier 9 by suspension means including means 13 for varying the distance between the press 1 and the carrier 9 in response to the load carried by the suspension means. The invention is applied to a press for use in nailing together parts of wood trusses and may be hydraulically or pneumatically operated. The carrier 9 is mounted on wheels 43 freely running on a rail 15 which is itself supported at its ends by two spaced parallel beams (not shown). Rail 15 is preferably driven along these beams by a fluid motor (45), Fig. 3 (not shown). The press-suspending means includes two mutually perpendicular pivot connections 47, 55 and a single-acting cylinder 49, piston (51) and pistonrod 53. Fluid pressure in cylinder 49 is arranged to nearly balance the weight of the press 1. Thus when the press is used for driving nailing plates (N1), N2 into pieces of timber (T1), T2, the press is automatically adjusted so that the platens 3, 5 drive the upper and lower nailing plates in simultaneously.
