Patent GB-1418735-A (GB)
Title: Internal combustion engine
IPC: F02B75/22
Filed: 1973-02-10
Abstract: 1418735 Internal combustion engines; reciprocating pumps D V SADLER 31 Jan 1974 [10 Feb 1973] 6661/73 Headings FIA and FIB  An internal combustion engine includes a crank having an output shaft 16 and an offset arm 17, a pressure chamber 31 in a wall 3a of which the arm is rotatable and slidable, the pressure chamber being axially and angularly oscillatable with accompanying rotation of the output shaft under the action of a piston 13 serving intermittently to pressurize the pressure chamber 31, the piston being reciprocable by fuel combustion in a combustion chamber 50 of the engine. The firing of combustible gas in the chamber 50 takes place when the piston 13 is at its upper position and when the pressure chamber 31 together with sleeve valve 3 connected to it is also at its upper position Fig. 2, (not shown); in this position the inlet ports 8 and exhaust ports 7 in the sleeve valve 3 are closed. Movement of piston 13 downwards on the firing stroke pressurizes oil in chamber 31 which forces the arm 17 outwards and so rotates the crankshaft 16. The crankshafts are provided, rotating in opposite directions. Movement of the arms 17 inwardly pressurizes chamber 31 causing piston 13 to rise. The charge already present in the combustion chamber 50 is thereby compressed; fresh charge is drawn into the engine at the same time through inlet ducts 32, valves 35 and chamber 37 which communicates with the underside of piston 13 via ports 9. The arms 17 are held in spherical bearings 10 of the pressure chamber body and lubricated by oil from the chamber passing along grooves (42, 43), Figs. 6-8 (not shown). The chamber is replenished by oil from a reservoir 20. The oil flows through valves 25, 26, the valve 25 being opened by the piston 13 in its lower position by an integral stem 27. A multiple cylinder arrangement may comprise three cylinders, the crankshafts of which carry intermeshing gears (18), and take-off shafts (45a) driving a common bevel gear (47) on an output shaft (48), Figs. 11,12 (not shown). Reciprocating Pump During reciprocation of the pressure chamber 31, an extension 11 thereof acts as a pump. The reservoir 20 communicates with a main reservoir (21a), Fig. 13 (not shown) via passage 21 and with a lubricating system (24a, b and c) via passage 24. Reciprocation of the extension 11 draws oil into reservoir 20 on an upward movement and forces oil into passage 24 on a downward movement. Oil also flows into pressure chamber 31 when the stem 27 opens the valve 25.

IPC: F03C1/28
Filed: 1963-02-21
Abstract: 961,273. Hydraulic motors. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI. Feb. 21, 1963 [March 23, 1962], No. 6960/63. Heading F1A. An hydraulic motor comprises a non-rotatable cylinder block 7 housing pistons 8 supplied by a rotary distributer 18 and drivingly engageable with the rollers 12 mounted on a rotor 9, the axes of the pistons being tangential to a circle c concentric with the motor axis, and the number of rollers plus or minus the number of working strokes performed by each piston during each revolution of the distributer being equal to the number of pistons or to a multiple thereof. The piston heads are shaped such that in the normal direction of rotation, anti-clockwise as shown, the force component acting to tilt the piston is a minimum, whereas in the opposite direction this force is a maximum. When the rotor 9 is acted on by an external torque in the anti-clockwise direction, the pistons act as wedges to resist rotation. The distributer may be constructed to provide one or more piston working strokes per distributer revolution and may be driven by the rotor through step-up gearing of a ratio equal to the number of rollers divided by the number of piston working strokes per distributer revolution. Alternatively, the distributer may be driven separately, the rotor then following the distributer. The distributer may rotate in the same or the opposite direction to the rotor. In the embodiment shown, each piston performs two working strokes per distributer revolution and the distributer has two high pressure ports 15, 21 and two low pressure ports 20, 22. The motor may drive through gear teeth formed on the rotor 9.

Filed: 1951-03-29
Abstract: Apparatus for use in the manufacture of a luminescent screen for a cathode-ray tube by a process of the type involving the deposition of a luminescent powder or powders on to the screen support from a suspension in a liquid, comprises a plurality of closed vessels for containing, in the form of liquids or suspensions, the ingredients for forming the deposition suspension, a sprinkler insertable within the cathode ray tube envelope for applying the ingredients to the surface of the luminescent screen support, and a closed feed system for conveying the ingredients to the sprinkler, the feed system including means for <PICT:0735633/III/1> controlling the quantity of each of the ingredients to be delivered to the sprinkler.  The four reservoirs 1, 2, 3 4 contain respectively demineralized water, an aqueous solution of the binder (such as potassium silicate), an aqueous solution of an electrolyte (such as sodium sulphate) and a concentrated suspension of the luminescent powder in water or in an aqueous solution of the binder, the reservoirs being all connected through a closed system of pipes and vessels to a sprinkler 5 disposed within the cathode ray tube envelope 6.  The reservoirs 1, 2 and 3 are each connected through a stopcock to graduated cylinders 7, 8 and 9 respectively, and the outlets from the three graduated cylinders are connected through stopcocks to a single pipe 10 which passes to a Buchner-type vacuum filter 11.  The outlet from the filter 11 is connected to a reservoir 12 for the mixed diluents, the reservoir 12 being connected to a vacuum pump.  The reservoir 4 is fitted with a rotatable stirring paddle 13 attached to the flanged detachable top 14 which is separated from the top and side of the reservoir by small gaps.  A tube 16 passes through an aperture in the reservoir wall and filtered air is blown therethrough.  The outlet from the reservoir is connected through a stopcock to a graduated cylinder 17 connected to a vacuum pump.  The outlet from the combination of the reservoir 4 and graduated cylinder 17 and the outlet from the reservoir 12 are connected through stopcocks 18 and 19 respectively to the sprinkler 5.  For preventing the entry of air from the atmosphere into the envelope 6 there is provided a cylindrical cover 21 attached to the hollow cylindrical stem 22 of the sprinkler 5. Filtered air can be blown through the envelope 6 through the tube 23.  The whole system can be washed out by passing demineralized water from the reservoir 1 through each of the cylinders 8 and 9 and by drawing water from the reservoir 1 through the remainder of the closed system via the cylinders 7, 8 and 9 and the stopcock 20.
