Title: Improvements in and relating to Jacks for Vehicles
Inventor: STORZ MATHILDE
IPC: B66F13/00
Filed: 1967-11-02
Abstract: 1,199,020. Screw jacks. M. STORZ and W. PLISCHKE. 2 Nov., 1967 [2 Nov., 1966], No. 49806/67. Heading B8J. Figs. 1, 3 show a car jack comprising a support column 10, attached to a tilting base 12, along which an extension 18 equipped with a lifting claw 28 is displaceable through a manually operated crank 46 driving a threaded spindle 42. The support column 10 slopes outwardly and upwardly away from the vehicle to be lifted, the extension 18 being pivoted on lugs 30 to a guide member 28 arranged to slide on the support column 10. The tilting base has two legs 14, 16, Fig. 1, showing the position in which the jack is fitted to the vehicle to be lifted. The lower part of the extension 18 rests on the column 10 through a sliding member 34. The lower part of the column 10 forms a stationary guide member 48 so that the extension 18 pivots from the starting position, Fig. 1, in which the lifting claw is a perpendicular distance a from the longitudinal axis of the spindle 42, to an end-of-pivoting position where this distance is b, Fig. 3, the support column 10 pivoting with the base 12 from the arm 16 to the arm 14. In a modification, Fig. 4 (not shown), an extension (50) is pivotally mounted within a support column 52 on a nut (56) on a spindle (54). Fig. 6 shows an embodiment in which the jack has a base 70 which maintains its position during the pivoting of a support column 72, pivoted thereto at 78, an extension 80 pivoted at 88 operating as described for the extension 18 above.

Title: Improvements in a Hot-Water Circulation Heating System for provided with a Domestic Water Heater
IPC: F24D19/10
Filed: 1966-11-09
Abstract: 1,157,134. Hot water heating and supply systems. JOH. VAILLANT K.G. 9 Nov., 1966 [22 Nov., 1965; 14 May, 1966], No. 50124/66. Headings F4A and F4U. A combined hot water heating and draw-off system comprises a burner 2, for heating water supplied through conduit 3 and a change over valve 7 to either central heating radiators 5, or heat exchanger 9 for heating draw-off water. Cool water from the radiators or the heat exchanger is then returned by pump 6 for reheating by burner 2. Under normal operation of the hot water heating system, hot water flowing through conduit 3 actuates thermally responsive element 24 causing it to expand so that valve closure member 12 seats against valve seat 11 thereby closing off the flow to the heat exchanger 9 and allows normal flow through conduit 3<SP>1</SP> to radiators 5. On start-up of the heating system, when the water through conduit 3 is not up to full operating temperature, the element 24 does not expand so far, thereby allowing some at least of the water from conduit 3 to by-pass the radiators through heat exchanger 9 to be returned to be heated by burner 2, so that the operating temperature is more quickly attained. On draw-off of domestic water through the valve 27, cold inlet water flowing through pipe loop 26 around element 24 exerts an overriding influence causing element 24 to contract so that valve closure member 12 abuts valve seat 10 and all the hot water flow from conduit 3 is diverted to heat exchanger 9. In a modification, Fig. 1, draw off of domestic hot water causes release of a control element 15  allowing a spring 14 to urge valve closure  member 12 against valve seat 10 to divert all flow from conduit 3 to the heat exchanger 9.  In operation of the heating system, the element 15. holds the valve stem head 13<SP>1</SP> against adjustable stop 18, despite the action of spring 14,  so that during start up conditions closure  member 12 almost abuts valve seat 11. When the flow from conduit 3 has reached operating temperature, expansion of the member 12 against the valve seat 11 closes off all flow through the by-pass to heat exchanger 9.

Each coil may correspond to a function in a set of independent binary functions, or a function in a set of Walsh functions or a number in a series of numbers forming a pseudo random sequence of such numbers or a number in a row or column of a Hedanard matrix.

Title: Radiation detecting arrangements

Filed: 1974-10-21
Abstract: 1490695 Electron multipliers EMI Ltd 21 Oct 1974 [3 Nov 1973] 51143/73 Heading H1D A multi-channel multiplier (e.g. photomultiplier) comprises dynodes 81 spaced along the tube length separating the envelope into separate channels with individual anodes, and window 61 including side-by-side obstruction regions aligned with the dynodes and extending at least partly through the window to inhibit cross-talk. In Fig. 2a showing one of a plurality of scintillators 3, metal inserts 11 are in glass window 61 backed with photocathode 71 and preferably each glass-metal interface is optically reflective. Window 61 may be a multi-layered glass metal or glass-metal alloy sandwich of materials of similar expansion coefficients (e.g. Kodial (R.T.M.) glass and Nilok (R.T.M.) metal alloy preferably coated with silicon nitride to prevent oxide formation). In fabrication the multilayered construction is heated and pressed to provide a fused window, the heating preferably being in vacuum to prevent entrapment of air. The glass layers may be silvered. A glass sheet may be attached to the underside of window 61. Slots 14 in Fig. 2(b) in one direction only may be cut by a diamond saw, the remaining window thickness supporting the pressure difference across the evacuated tube wall. A metal strip which may be polished or silvered may be provided in each slot and the slot then filled with epoxy resin. The radiation obstruction regions may alternatively be lenses. The window thickness may be c. 6-10 mm. Reference is included to a photomultiplier as in Specification 1,470,162, and apparatus in which radiation is scanned over a body to be examined as in Specification 1,283,915.

Title: Hydraulic actuator controls disazo pigment
IPC: F15B13/043
Filed: 1972-11-08
Abstract: 1406326 Fluid-pressure servomotor systems SPERRY RAND Ltd 7 Nov 1973 [8 Nov 1972] 51471/72 Heading G3P In an hydraulic system for maintaining the speed of an actuator constant, variations in the rate at which fluid is expelled through a sensor 74 from the actuator cause variations in a feedback signal applied to a pilot valve 19 which is positioned in accordance with an electrical signal to a transducer 52 and controls a main valve 20 regulating the supply to the actuator. A shuttle valve 61 controlled by the signals in lines 53, 54 from the pilot valve to the main valve reverses the feedback signal when the actuator is reversed so that the signal applied by the transducer is always opposed. The pilot valve receives its supply through a pressure reducing valve 50 while the main valve is connected with a supply line 32. Non-return valves 85, 86 prevent cavitation when the actuator is driven by the load. In further embodiments, the actuator is replaced by two single-acting rams (90, 91), Fig. 2 (not shown), and the flow sensor is positioned in the supply line to the main valve, the shuttle valve being modified, or the flow sensor is positioned in a load line to the doubleacting actuator and the shuttle valve rendered ineffective by blocking its spool with a plug (101), Fig. 3 (not shown). In Fig. 5, a flow-control pilot valve 19 connected to a transducer 52 controls a main valve 20 connected by service lines 30, 31 to an actuator (not shown) and receives a feedback signal from a flow sensor 74 through a shuttle valve 60 while a further pilot valve 118 connected to a transducer 121 may be put into controlling relationship with the main valve by energizing the transducer 52 to displace the pilot valve 19 fully to the right, the pilot valve 118 receiving a feedback signal from the service lines 30, 31 through a shuttle valve 113 so that the transducer 121 determines the pressure difference across the actuator. Needle-like plungers 129, 130 slidable but sealingly guided in outer lands of the pilot valve 118 make the chambers 131, 132 receiving the feedback signal of unequal area so that the pressure difference between these chambers can oppose the force of the transducer. If a shock load is applied to the actuator, this pressure difference is increased to displace the spool of the pilot valve sufficiently far to uncover a port 125 and connect a pressure supply line 126 to drain so that the main valve is centred to isolate the service lines 30, 31. Under these conditions, a spring 138 displaces a valve 133 to connect the high-pressure side of the actuator to drain until restoration of pressure in line 126 restores the valve 133 to its original position and normal operation is resumed. The flow sensor may be constructed as described in Specification 1335042 and the pilot and main valves as described in Specification 1361680.
