Title: Method for the production of helical protein products
Inventor: TREHARNE TIMOTHY JOHN MINGAY
IPC: A22C11/00
Filed: 1984-03-09
Abstract: The helical protein product comprises abutting or non-abutting coils, and is made by positioning an injector tube 22 within a substantially cylindrical mould 5, and withdrawing the nozzle from the mould 5 parallel to the cylindrical axis thereof, whilst extruding proteinaceous product forming material from the tube so that the material is deposited in a substantially helical form upon the inner surfaces of the walls of the mould, rendering cohesive (by heat or acid coagulation) at least those regions of the said form which are in contact with the inner surfaces of the walls of the mould, and thereafter removing the product from the mould. Further material may be extruded into a central cavity of the form. The nozzle outlet may be directed towads the mould walls and the nozzle and mould may relatively rotate during extrusion. The mould walls may be pretreated with coagulating acid, or the acid may be admitted from a mould reservoir 6 via porous walls 5, 14, and a porous wall 28 of an end cap 26 (Fig. 2). <IMAGE>

Title: Solid state switch
Inventor: BLOICE JOHN ANTHONY
IPC: G08B13/19
Filed: 1984-08-15
Abstract: A bi-lateral switch circuit comprises two similar solid state switches, the first comprising a C MOS oscillator circuit 7,8,9, R22 and R34 adapted to oscillate only upon receipt of a high level signal A. A pair of V MOS transistors TR11 and TR12 connected in series opposition have their gates coupled via isolating capacitors C11 and C12 and a rectifying circuit, e.g. a voltage tripler D11-D14 and C15-C17, to the oscillator output so that the V MOS transistors conduct only when the oscillator circuit is oscillating. The second switch operates on receipt of a high signal B, thus providing the equivalent of a pair of isolated relay contacts for controlling an alarm device when the inputs A and B are the normally high and normally low outputs, respectively, of an infra-red intruder detector. <IMAGE>

Title: Riser shroud
Inventor: JEE TREVOR PETER
IPC: E02B17/00
Filed: 1985-01-31
Abstract: A vortex spoiler for a riser 2 comprises a perforated shroud 1 adapted to surround and be spaced apart from the riser. Vortex shedding around a riser can lead to high and low pressure variations on the riser which can set up damaging vibrations. The spoiler reduces the formation of such vortices and thus protects the riser, and is preferably installed at mid-span of the riser. It may be of plastics, and may incorporate anti-fouling mesh. <IMAGE>

Patent GB-2171149-A (GB)
Title: Rotary internal combustion engine
Inventor: CORTES MARFIL ANTONIO
IPC: F02B53/02
Filed: 1985-11-21
Abstract: An internal combustion engine comprises a fixed crankshaft about which an assembly of a drum 1, pistons 2 and piston chambers 7 rotates in use. The pistons 2 are mounted on the drum for rocking movement and engage the fixed crank pin 5 of the crankshaft by way of sliding surfaces 6. Rotation of the drum 1, pistons 2, and chambers 7 assembly in use tends to throw the pistons radially outwardly, and this effect is used to compress the working mixture during compression strokes. During power strokes the centrifugal forces on the pistons help to contain the chamber gases resulting in a reduced load on the crankshaft. Counterweights (29, Figure 3) may be provided to counteract the centrifugal forces. <IMAGE>

Patent GB-2195419-A (GB)
Title: A projectile
Inventor: AHLERS UTZ UDO
IPC: F42B14/02
Filed: 1986-09-26
Abstract: A projectile (2) which can be fired in a spin-stabilised manner from a barrel (11) by means of gas pressure from a propulsion charge and can be steered in flight is intended to be designed, in the interests of achieving defect-free unfolding capabilities for sliding surfaces and control surfaces which are overcalibre and are therefore folded in during firing, to have only a reduced initial spin with respect to the geometry of the traction-field profile on the inner wall (14) of the barrel. For this purpose, the projectile tail structure (1) is equipped with a sealing ring (4) which can rotate while being frictionally locked thereto and has a sliding ring (9) which is extrusion-coated with a plastic body (10). Inserts in the form of bent flanges (18) ensure the adhesion, which is rigid in terms of movement, between the plastic body (10) and the sliding ring (9) while the sealing ring (4) is being stressed in shear and torsion in the barrel (11) and while it is being stressed centrifugally after emerging from the muzzle of the barrel. <IMAGE>

Title: Preparing a pumpable slurry of fibrous lignocellulosic material
Inventor: RUYTER HERMAN PETRUS
IPC: D21C1/02
Filed: 1986-09-29
Abstract: A method of preparing a pumpable slurry of fibrous lignocellulosic material and water comprises passing particles of fibrous lignocellulosic material into a mixing chamber and heating together with water at a temperature in the range 100 to 300 DEG C and at a pressure which is above the vapour pressure of water at that temperature, and passing the resulting mixture through a restricted opening under pressure. The pumpable slurry may be readily passed through a pipeline for further processing as a feedstock or for use in preparing moulded products. Binders and dyestuffs may be added to the lignocellulosic material either before or during mixing with water in the mixing chamber. The lignocellulosic material may be wood in the form of chips, pellets, or sawdust.

Title: Interlocking containers
Inventor: HOLDT JOHN WARREN VON
IPC: B65D25/20
Filed: 1986-11-10
Abstract: A container 10 is provided with externally positioned interlock means 15 to engage the corresponding interlock means of other identical containers positioned side-by-side. This causes the containers to be temporarily retained together without relative motion transverse to their axes except for possible rotational motion about their axes. Additionally, relative motion parallel to their axes can be prevented. Significant advantages are achieved by this when the containers are being processed along a conveyor system, and when they are stacked in large stacks. The interlock means may comprise circumferential toothed racks 22,24 defining alternating projections 26 and recesses 28, eg of conical shape, walls 30 preventing the projections fitting into the recesses from moving in the direction parallel to the axes. The container may be of rectangular cross section with rounded corners, the corners having projections and recesses while the straight sides have ridges and slots (Figs. 7-9). A plurality of rows of such horizontally interlocked containers may be surrounded by a strap and stacked with another layer of strapped, interlocked containers, (Figs. 10 and 11). <IMAGE>

Abstract: The invention relates to a microprocessor set-up. A set-up, including a microprocessor 1 and a reset circuit 2, controls at least one output stage T1, S 9, 10 including a switching transistor T1. In order, by simple means, to avoid the destruction of the switching transistor T1 in the event of a short-circuit, a threshold-activated interrupter R2, T2 is coupled up to the switching transistor T1. The latter reacts in the event of a short-circuit, so that the reset circuit 2 resets the microprocessor 1 in such a way that the switching transistor T1 is blocked. <IMAGE>
