Title: Fuel injection pumping apparatus
IPC: F02M59/10
Filed: 1973-05-12
Abstract: 1470166 Fuel injection pumps CAV Ltd 29 April 1974 [12 May 1973] 22717/73 Heading F1A Fuel injection pumping apparatus includes a displacement piston 30 slidable in a cylinder, a delivery outlet 33 communicating with one end of the cylinder, and valves 18, 22 operable to connect, via a passage 16, the other end of the cylinder alternately to an accumulator 10 and a drain 21 in response to signals indicative of the position of the piston 30. In the injection stroke end position shown, the valve 18 is open whereby the passage 16 is connected to the accumulator 10 but delivery through the outlet 33 is prevented by an injection valve 34 urged against its seating by the piston 30 acting through a push piece 36. The return stroke of the piston 30 commences when a stack of Piezo-electric crystals 24 are de-energized. This causes, via mechanical linkage (23, 25), Fig. 1 (not shown) or fluid trapped between pistons 26, 27a, closure of the valve 18 and opening of the valve 22. Thus pressure in the passage 16 is lost to the drain 21 and the pressure loading of a valve 32 removed to allow the latter to open whereby fuel from a passage 31 causes the piston 30 to return. The extent of the return stroke is indicated by a signal derived from a sensing coil 27 and applied to an electronic control circuit 26a. The circuit 26a causes the partial energization of the crysal stack 24 and consequential closure of the valve 22. When injection is required the crystal stack 34 is fully energized to open the valve 18 for accumulator pressure to close the valve 32 and actuate the piston 30. The co-axial configuration of the valves 18, 22 may be replaced by a parallel arrangement, Fig. 3 (not shown). In a further embodiment, (Fig. 1), the fuel displaced by the piston is injected directly into the cylinder of the associated engine and fuel enters the one end of the cylinder through a non- return valve (28).

Title: A method of preparing a permanent suspension of particles in liquid
Inventor: BURROWS GODFREY
IPC: C09K23/00
Filed: 1953-08-19
Abstract: Fine particles are mixed with a metal soap and a hydrocarbon oil, the mixture heated to form a gel holding the particles in suspension, the gel allowed to cool whilst stirring to form a viscous liquid, and any oil which separates is removed.  Suitable metal soaps may be derived from stearic, palmitic, oleic or other fatty acids.  In the Example, aluminium or lithium stearate ( 1/2 part by weight) and iron powder (100 parts) are mixed dry and a pure hydrocarbon oil of low vapour pressure (20 parts) incorporated therewith.  The mixture is then heated whilst stirring continuously at at least 110 DEG C. (aluminium stearate) or 210 DEG C. (lithium stearate) and preferably 10-20 DEG C. thereabove.  The composition is then allowed to cool with stirring, and after remaining undisturbed for at least several days, the supernatant oil is removed.  Such dispersions of iron powder may be used as magnetic clutch fluids.  It is stated that if suspensions made with aluminium or lithium stearate are heated to above 100 DEG C. or above 200 DEG C. respectively, they must be stirred whilst cooling, to recover their original properties.

Title: Hydraulic elevator
IPC: B66B1/04
Filed: 1966-05-23
Abstract: 1,148,455. Hydraulic control systems for lifts. COAST ELEVATOR CO. 23 May, 1966 [17 Sept., 1965], No. 22879/66. Heading B8L. [Also in Divisions F1 and G3] An hydraulically operated lift is decelerated as it approaches its required stopping position and completes its travel at a slower uniform speed so as to allow almost instantaneous stopping. As shown, a pump 12 supplies fluid via line 14 to a cylinder containing a liftraising piston 10. A by-pass valve 18 in bypass line 20, 22 is biased to an open position by spring 28 and by line pressure acting on piston 26A, and is closed by line pressure acting via restriction 34 on piston 26, the latter pressure being modulated by valves 38, 48 which control the leakage from chamber 27. During starting, valve 18 is open but a small backpressure is generated and this acts in chamber 27 (valve 38 being closed) to close valve 18 to a small extent, this action increasing the backpressure and causing further closure of valve 18. This action is self perpetuating and valve 18 closes to allow all of the fluid to pass to cause movement of piston 10. During this starting process, the piston accelerates to a relatively high uniform speed. As the lift approaches its destination solenoid-operated valve 38 is opened to vent chamber 27 to allow the by-pass valve to move towards its fully open position. The flow to piston 10 therefore decreases but, at a predetermined flow rate, a check valve 44 causes valve 48 to restrict the vent line 36. Valves 44, 48 then function to maintain movement of the lift at a relatively low uniform speed by preventing complete opening of the by-pass valve. When the lift reaches its destination it is stopped virtually instantaneously by causing pump 12 to stop or by causing a dump valve to open to by-pass all the output of the pump.

Abstract: 723,386. Magnetic recording and reproducing apparatus. ARMOUR RESEARCH FOUNDATION OF ILLINOIS INSTITUTE OF TECHNOLOGY. Sept. 17, 1952 [Sept. 26, 1951], No. 23394/52. Class 40 (2) In a magnetic head one alternating field is arranged to produce a flux at the recording gap at right-angles to a second alternating field whereby a resultant field is produced which rapidly decays in the region of the trailing pole. In embodiments employing a three-limbed core 11 or 26 forming a combined crazing and recording head, such as in Figs. 1 and 5, a coil 12 produces an erazing flux A which, in the region of the recording gap 25, is at right-angles to the biasing flux B set up by biasing coil 13 or 28, respectively, to produce a resultant flux C, Fig. 3. In the embodiment shown in Figs. 9, 10 and 11, Figs. 10 and 11 not shown, the eraze coil 53 serves to magnetize an eraze gap which is spaced sufficiently far from the recording gap not to have any substantial effect on the bias field in the recording gap. The second field is then produced solely by an auxiliary coil 57 on an additional limb 56. In the embodiment, shown in Fig. 8, the second field is produced by coils 42 on limbs 43, 44.,
