Patent GB-2043780-A (GB)
Title: Hydraulically Operated Actuator
IPC: E21B34/00
Filed: 1980-02-22
Abstract: A hydraulically operated actuator employs multiple metal-to-metal static seals to isolate the hydraulic fluid and to isolate the actuator from surrounding contaminating (ambient) fluids, the seals becoming operative only at the completion of power and return strokes of the actuator piston 30. A housing contains at least two linearly spaced apart chambers, 13, 14, 15 the piston 30 moving between retracted and extended positions in the chamber 14. A first static metal seal ring unit 35 seals against a shoulder 52a at the completion of the piston's power stroke to isolate fluid in chamber space 14 from external contaminating fluids. A second static metal seal ring unit 42 seals at the completion of the piston's return stroke. Power for the return stroke is primarily supplied by springs 26, (26a), assisted by biasing pressure from the external environment. The actuator may be employed to operate a subsurface safety valve used to control flow of fluids through a well tubing and may be located external of the well tubing with the piston rod 44 being linked to a valve operator. Means may be provided to compensate for any differences in travel between the piston and valve operator. <IMAGE>

Title: Regeneration system for a hydraulic intensifier unit
IPC: G05D16/10
Filed: 1980-11-07
Abstract: A hydraulic intensifier for oil well fracturing and/or erosion drilling, having a pair of sequentially operated reciprocating ram assemblies (A and B) powered by hydraulic cylinder motors (HCA, HCB). The return face side of the pistons (12, 30) have a smaller operative area than the working face sides and each can be connected selectably via a valving unit (MS2) either to tank (40) or to the main source of supply of hydraulic fluid to the working faces so that as the pistons are driven to their extended positions by application of hydraulic pressure to the working face, the fluid on the return face side can be expelled from the cylinder motors and returned to the working face side to either reduce the fluid flow from the source while maintaining the same cycling rate or maintaining the same flow from the source by increasing the cycling rate and thus increasing the total volume flow. <IMAGE>
Patent GB-2058524-A (GB)
Title: Dimensional sound producing apparatus and method
IPC: H04S1/00
Filed: 1980-04-04
Abstract: Sound reproducing system having right and left speakers, (S(R) and S(L)), respectively, which produce right and left stereo sounds, respectively (Fig. 3). A right stereo signal in addition to driving the right speaker (S(R)), is inverted (B(RL)) and delayed (b1(RL) to b4(RL)) to produce a compensating signal which is transmitted to the left speaker (S(L)) to produce a delayed compensating sound pattern from the left speaker. The signal for the left speaker (S(L)) is inverted (B(LR)) and delayed (b1(LR) to b4(LR)) in a manner to produce a compensating sound pattern from the right speaker. The compensating sounds substantially cancel the main stereo sounds (R1 and Lr) travelling to a person's ear (Re and Le) that is further from that speaker, to produce a dimensionalized effect where some of the sounds appear to be outside of the speaker area. In a second embodiment, the main stereo signals and the compensating signals are used to produce a recording (Fig. 10) which in turn produces the main stereo sounds and the compensating sounds to produce a dimensionalized effect.

Title: Collapsible divider for car boot
Inventor: WILKINSON DOUGLAS JAMES
IPC: B60R7/02
Filed: 1981-04-15
Abstract: A collapsible device for the division of a vehicle booth compartment into a number of separate storage compartments has vertical dividers 1 and 2 placed lengthways and transversely in the boot compartment which are slotted into each other at 7 and supported by bobbins. The device is positioned in the motor vehicle on the boot compartment floor and located by the ends of the divider sections abutting against the inside of the boot compartment walls.

Title: Operating handle for a control device
IPC: F16K31/44
Filed: 1981-11-03
Abstract: An operating handle for a control device having a control element 11 capable of separate axial and rotational movement is so constructed that each movement is only possible when the handle is in the neutral position for the other movement. The handle consists of a shaft 1 which is rotatable in a sleeve 13 to provide the rotational movement of the control element, the handle being coupled to the control element by means of a pivot pin 10. The sleeve 13 is hinged off its axis using a stay 16 and a link 18, so that the pivotal movement of the shaft causes axial movement of the control element. Therefore, the hinge axis of the sleeve is parallel to the axis of the pivot pin 10. A collar 21 is provided on the shaft for engaging a projection 25 fixed to the body of the control device and a peg 8 secured to the shaft to hold the handle in the neutral position. <IMAGE>
