Title: Improvements in jet-propulsion units for water craft
Inventor: HUBER LUDWIG
IPC: B63H11/00
Filed: 1968-12-23
Abstract: 1,223,700. Water jet-propulsion. L. HUBER. 23 Dec., 1968, No. 61058/68. Heading B7V. In a water jet-propulsion unit a primary  water stream is driven by a rotary pump and  itself accelerates a secondary water stream, the  pump comprising blades concave on their leading sides and carrying a shroud ring which extends axially beyond the blades and contains a guide blade device to withdraw water. Primary water B passes through openings 13a in headpiece 2 to blades 18 connecting rotors 11a, 11b, and is directed peripherally and axially into shroud ring 20. Guide device 21 has curved blades 23 which divide off the inner portion of the rotating water and direct it through passages into pipe 9. Device 21, pipe 9 and passage 10 form an injector so that the primary water draws secondary water through inlet 17 passage 10 and pipe 9. A second injector is formed by piece 7, pipe 9 and pipe 4 to draw in further secondary water through annular gap 8. Shroud 20 and rotors 11a, 11b are driven by a belt 29.

Title: Frame element for fish husbandry framework
IPC: A01K61/00
Filed: 1978-10-06
Abstract: A frame element (10) for threading onto beams via holes (4) to form a framework for use on the seabed in fish husbandry is hot press moulded from a mixture of plastics waste, sand and a thermoplastic binder and has limbs (1) formed with recesses (2) in its surface.

Title: Fuel Supply System for Internal Combustion Engine
IPC: F02M41/14
Filed: 1979-07-23
Abstract: A pump for use in an accumulator type fuel system for supplying fuel to an engine includes a high pressure pump to which fuel is supplied by way of a throttle 15, 16 by a low pressure pump. A valve is provided to control the output pressure of the low pressure pump and the outlet of the high pressure pump is connected to the accumulator. The setting of the throttle is determined by a piston combination comprising pistons 29, 34. The smaller of the pistons is subject to the pressure in the accumulator and the larger piston to the output pressure of the low pressure pump plus the pressure of a spring 32. The piston combination controls the throttle so that the accumulator pressure is higher than the output pressure of the low pressure pump by a predetermined ratio. <IMAGE>

Title: Fuel injector for an internal combustion engine
IPC: F02M61/06
Filed: 1979-10-29
Abstract: A nozzle needle (2) slidable in a nozzle body (1) terminates in a pintle (4) slidable in a central outlet bore (5). A pressure space (7) is arranged between the valve seat (3) and the pintle (4). The pintle (4) has a longitudinal bore (8) and a transverse port or bore (9) communicating therewith, and an annular gap (6) between the wall of the central bore (5) and the pintle (4) provides an atomised spray at low speeds and/or loads. The transverse port or bore (9) terminates within the central bore (5) when the nozzle needle is closed and connects the space (7) with the bore (4) after a predetermined lift of the nozzle needle (2) to provide a compact fuel jet at higher speeds and/or loads. The pintle (4) extends over substantially the full length of the central outlet bore (5) when the nozzle needle (2) is fully open, thereby preventing an increase in atomised spray. <IMAGE>

Title: Explosion-proof diesel locomotive
IPC: F02B3/06
Filed: 1979-11-30
Abstract: In an explosion-proof diesel locomotive, the controlling, monitoring, protecting and indicating system has a pneumatic two-way selector switch (4) for setting between "EXPLOSION PROOF" and "NORMAL" mode of operation and the switch position is displayed on the outside of the locomotive. For this purpose, the actual position of the selector switch (4) for changing the mode of operation is conveyed to a signal display board with indicators mounted on each side of the locomotive which is well readable from a distance, and to the instrument panel in the driver's cabin. When in the "explosion proof" mode, the locomotive is less likely to initiate an explosion during travel through an environment which is liable to explosions. <IMAGE>

Title: Initiatory Explosives Comprising a Lead Salt of 3,5- Dinitro-catechol
IPC: C06B41/02
Filed: 1979-12-05
Abstract: An initiatory explosive comprises the anhydrous normal lead (II) salt of 3,5 dinitro catechol (3,5-dinitro 1,2 dihydroxy benzene), which may be used alone or form part of an explosive composition mixed for example with oxidants, sensitizers etc. The explosive may be conveniently prepared by the reaction between dinitrocatechol and a suitable lead compound, or by double decomposition, in aqueous media, and is suited for production in situ in an explosive device. It has a mechanical sensitivity as good as conventional materials such as lead styphnate or resorcinate, but has a considerably lower electrostatic sensitivity, which leads to safer handling. The explosive and compositions containing it are suitable for use in most initiatory explosive devices such as percussion caps and stab sensitive detonators as a simple substitute for conventional materials.

Title: Process for producing extruded rigid thermoplastic sheet having optically smooth surfaces
IPC: B29C48/07
Filed: 1979-01-10
Abstract: The sheet comprises a thermoplastic having a heat distortion temperature of at least 70 DEG C (by defined measurement) and optically smooth surfaces, characterized as exhibiting a degree of (defined) optical distortion ( delta ) of from 0.03 to 0.06, and is produced by polishing a sheet-form extrudate issuing from an extruder by means of polishing rolls which are driven by a final transmission which continuously transmits the driving force, to avoid cyclic speed variations. The rolls may be driven by a single motor with the transmission being a fluid coupling or torque converter, or a flat belt, or contacting roller or cone. Alternatively, a direct driving motor may be employed. Preferably, specified controls are also exercised over the process temperature, the extrusion rate, and the amplitude of high frequency apparatus vibrations. The thermoplastic may comprise a methyl methacrylate polymer, polycarbonate polystyrene, or rigid P.V.C., and the sheet may be formed into signboards, displays, or room light covers.

Title: Washing operation
IPC: C23G3/00
Filed: 1981-04-04
Abstract: Parts or components (7) in a washing region of tank (1) are washed with a washing solution supplied to nozzles (12) from side tanks (10 and 11) either by spraying said parts or components (7) or by rapid pumping of said washing solution through said nozzles (12) when the washing region is filled with washing solution. The washing solution is extracted from the washing region and is rapidly circulated by means of a pump (3) until a measuring cell (6) detects that the level of contamination has reached a predetermined value. A valve (4) is then operated to switch to a purifying mode wherein the washing solution is pumped via a purifying means (5) until the level of contamination falls to a predetermined level as measured by measuring cell (6A). The valve (4) is then reinstated into the washing mode for direct pumping of the washing solution through the washing region. The alternation between the washing mode and purifying mode is continued until the rise in the level of contaminant entering into the washed liquid falls to a predetermined level as monitored by the measuring cell (6) whereupon a required degree of decontamination has been achieved. <IMAGE>
