Title: Gravitationally locked structural joint
Inventor: PERKS ARTHUR THOMAS
IPC: E04B1/24
Filed: 1993-09-06
Abstract: Gravitationally Locked Structural Joints join together structural members from all angles, free from external encumbrances (Fig. 5), such as bolts, clamps or the like that can be speedily and accurately assembled and dismantled on site without hand tools or the like; is a nonslip joint thereby eliminating manual frailties by way of example failure to tighten bolts or any other necessary operations. Gravitationally Structural Joints may consist of Square Hollow Section uprights (1) and Square Hollow Section horizontals (2) which have "T" shaped lugs (4) on their ends. Assembly, by way of example, can be achieved by standing uprights on end for a multiplicity of horizontals with lugs (4) to be hooked into uprights to fill hollow section (Fig. 1) for the next upright to be placed onto upper protruding lugs (4) to complete the joint. Brace Struts (5) may be telescopic and have swivel round or angular logs (4) mounted on blanking off plates (3). <IMAGE>

Title: Forming building products by continuously moulding about a travelling soft polymer core
Inventor: GUETTLER ARNOLD
IPC: B28B19/00
Filed: 1995-04-07
Abstract: A pultrusion process involving the insertion of a soft polymer core into a pultrusion mandrel, see Figure 1. As the core progresses, it is encased with a cementitious material, which is pumped into the top of the mandrel, thus filling the void between the outer surfaces of the core and the inner surfaces of the mandrel. The building material sets slightly in the pultrusion form, and is conveyed through a curing process, consisting of adjustable concrete slabs with the provision for either heating, cooling and steam inducement, or a combination of all three curing features. Furthermore, by using pressure elements which compress the concrete slabs against the cementitious coating, excess moisture is expelled from the building material. The finished building material emerges as a continuous single panel, which is strong enough to stand unsupported. The panel is then cut into predetermined lengths, prior to shrink wrapping, palletization and storage.

Title: Scraper for chain bands of double-centre chain scraper conveyors
Inventor: MATERNE KURT ANDRE
IPC: B65G19/24
Filed: 1996-01-10
Abstract: In the scraper for chain bands of double-centre chain scraper conveyors, the chain shackle (4) is shaped in such a way in the direction of the scraper longitudinal axis that, during mounting with an inserted double-centre chain, the said chain shackle first comes to bear on those two legs (3a) of the horizontal chain links (3) located towards the centre of the scraper, in order, when the screw connection (10, 11) is tightened further, additionally to clamp the outer legs (3b) of the chain links. When a defined mounting force has been reached, the inner and outer chain-link legs are clamped with the same force. The convex curvature of the shackle, in contrast to the straight shackle, prevents the shackle from lifting off from the inner chain-link legs due to the bearing effect of the outer chain-link legs. An always uniformly distributed and permanently firm and reliable chain clamping is thereby guaranteed.

Title: Deep water riser assembly
Inventor: REYNOLDS GRAEME E
IPC: E21B33/038
Filed: 1996-11-19
Abstract: A deep water riser assembly extends between a drill ship 12 and the bottom of the ocean and includes a lower BOP stack 34 on the bottom of the ocean. An assembly of riser pipe joints 36 extends upwardly from the lower BOP stack to an upper BOP stack 40 attached to the riser at a water level just far enough below the surface to be unaffected by surface currents. The upper BOP has lower pipe rams to engage the drill pipe and seal the annulus between the drill pipe and the riser and shear rams above the pipe rams to sever the section of the drill pipe above the shear rams to allow the upper section of the drill pipe between the shear rams and the drill ship to be retrieved followed by the section of riser above the upper BOP to free the drill ship to move as required to better weather a surface storm. A floatation module 38 is attached to the riser below the upper BOP stack. Means are provided to reconnect the upper section of the riser to the upper BOP stack after the storm has passed after which the severed joint of drill pipe and the lower section of drill pipe is recovered, the severed section removed and the drill pipe is run back into the hole. Multiplex electrical conductor cables extend from the surface to the upper and lower BOP stacks to supply power to open and close the preventers. Reels are positioned at the upper BOP stack to store ample multiplex electrical conductor cable to allow the position of the lower BOP stack to vary while the upper BOP stack remains about the same distance below the surface.

In a side collision, lower arm-rest part 24 is pushed by the other vehicle against the pelvis of the occupant. The lower part 24 of the arm-rest is easily deformed by impact of the occupant so that there is little absorption of energy at the ilium of the occupant and energy is actively absorbed only at the femur. Alternative connections between the upper and lower door trim parts are described (figures 7,8).
Patent GB-2321051-A (GB)
Title: An applicator for dispensing metered doses of a liquid
Inventor: DENT HUGH ROBERT
IPC: A61M5/28
Filed: 1997-01-14
Abstract: An applicator for dispensing measured doses of a liquid comprises a cylinder 10, an elongate plunger 11  including a piston 12 slidable within the cylinder to discharge liquid from the cylinder through an outlet 14 at one end, and a spring 24 biasing the plunger away from the outlet. Longitudinal slots 25 of different lengths are formed around the periphery of the plunger, and by rotation of an annular stop member on the cylinder, an inwardly projecting pin 30 on the stop member may be brought into alignment with any selected one of the slots 25. As the plunger is biassed away from the outlet by the spring, to draw liquid into the cylinder, the selected slot slides over the pin 30 until it comes into engagement with the closed end of the slot. The distance by which the plunger is withdrawn from the cylinder, and hence the volume of liquid drawn into the cylinder, is therefore determined by the length of the selected slot. Accordingly, the volume of liquid to be discharged may be pre-selected by adjusting the rotational position of the stop member 29. The applicator may be used as a drench gun for dosing animals with liquid medicament.
