Patent GB-559931-A (GB)
IPC: B63B35/04

Title: Apparatus for controlling the operation of fluid pressure  motors
IPC: F15B9/12
Filed: 1972-12-06
Abstract: 1445680 Fluid-pressure servomotor systems AUTOMOTIVE PRODUCTS Ltd 6 Dec 1973 [6 Dec 1972] 56347/72 Heading G3P A servomotor ram 11 is controlled by an electric motor 18 which drives a lead screw 19 to axially move a nut 21 acting through a floating lever 22, link 32 and a further lever 33 upon the spool 14 of a pilot valve 13 regulating the flow of working fluid to ram 11, the lever system forming part of a feedback mechanism. The latter also includes a spring-loaded telescopic link 41 connected to lever 22 and having a roller follower 43 engaging a ramp 17 movable with ram 11. Motor 18 is of stepping or synchronous type controlled from an electronic converter 38 having limit switches 39 co-operating with nut 21. Lever 33 is provided with spaced holes 35, any one of which may be mounted on fixed pivot pin 34 so as to vary the movement imparted to spool 14 for a given movement of nut 21. A stop pin 36 engaging slot 37 limits angular movement of lever 33. Should pin 36 come up against the end of slot 37 as a result of ram 11 lagging behind motor 18, floating lever 22 pivots about its connection to link 32 causing telescopic link 41 to expand or contract until ram 11 has caught up. Disposed in the working fluid lines 59, 62 and 61, 63 from pilot valve 13 to respective sides of ram 11 are valves 46, 47 which are normally held open by supply pressure communicated via passage 72 in a plunger 65 of cut-off valve 64 to closed chambers at the left of plungers 49 in the valves 46, 47. Should the supply pressure fail then spring 71 of valve 64 urges plunger 65 rightwards to cut-off the supply pressure to the said chambers adjacent plungers 49 and simultaneously to vent the chambers to drain via passage 73 in plunger 66. Plungers 49 thus move leftwards under the action of springs 54 causing plunger heads 56 to seat and cut-off communication between pilot valve 13 and ram 11. To enable emergency control of the latter lines 74, 75 can direct working fluid from a hand pump or other source via valves 46, 47 to the ram. For example, if emergency working fluid is supplied to line 74, head 55 of plunger 48 in valve 46 unseats against the action of spring 54 thus communicating the supply pressure via line 62 to one side of ram 11. Simultaneously the supply pressure acts on floating piston 57 of valve 47 causing plunger head 55 to unseat and vent the other side of ram 11 to drain via lines 63, 75. During emergency operation the telescopic link 41 undergoes expansion and contraction since nut 21 remains stationary. In a modification the roller follower 43 is not carried on the telescopic link 41 but is pivotally connected thereto by a bell-crank (24, 25) Fig. 1 (not shown).

Title: Methods and apparatus for conveying the electrolyte into the gas chamber of gas-diffusion electrodes
IPC: H01M8/04223
Filed: 1966-12-19
Abstract: 1,114,489. Pumping electrolyte into a fuel cell electrode gas space. SIEMENS-SCHUCKERTWERKE A.G. and VARTA A.G. 19 Dec., 1966 [23 Dec., 1965], No. 56800/66. Heading H1B. Electrolyte is driven into the gas space of a fuel cell gas-diffusion electrode by means of the energy released upon expansion of either (a) the compressed fuel and/or oxidant gas from its storage pressure to a lower pressure not below that of the gas at the electrode inlet, or (b) the exhaust gases leaving the electrode. The expanding gas may drive a piston rigidly connected to another piston which pumps the electrolyte into the gas space of the electrode; preferably the piston is double-acting and is rigidly connected to two electrolyte pump pistons with complementary cycles. Suitable single- and double-acting pumps are described, together with valves for reversing the direction of travel of the double-acting piston and pneumatic, hydraulic or electric switches for operating the valves when the piston is at the extreme positions. In the general system shown in Fig. 1, gas from the tank 1 is led via the reducing valve 3 to the expansion engine/electrolyte pump 7 or to the reducing valve 5 and from these via pipe 9 to the fuel cell battery 10.

Abstract: 1,240,998. Rear view mirrors. P. H. MANNING. 12 Dec., 1968 [16 Dec., 1967], No. 57267/67. Heading B7J. A rear view mirror assembly in a vehicle comprises a mirror 30 clamped to an arm 26, 27 which passes through, e.g. outer and inner wheel arch panels Y and X respectively, and is slidable relative to the vehicle between an extended and a retracted limiting position defined by stops (not shown) by rotation of a flexible shaft assembly operable from the vehicle driving position and connected to rotate a pinion 16 in mesh with a crown wheel 14 secured to the same shaft 13 as a friction roller 15 bearing on the surface of the arm. An inclined groove 15a is provided on roller 15 and engages with a follower, e.g. the corner of a square arm 26, so that particularly at either limiting position of the arm continued rotation of roller 15 causes the roller to lose frictional grip and enables the angular disposition of the mirror about the longitudinal axis of the arm to be adjusted. The shaft 13 is rotatably mounted on side plates 11, 11 of a housing 10 having welded pivot elements 18, 18 pivotally mounted in a bracket 17 secured by a nut 24 and hollow bolt 25, through which the arm passes to the panel X. A nut 22, bolt 21 and washer 23 arrangement on the housing 10 frictionally bears on an arm 20 of bracket 17 to prevent pivoting between the housing and the bracket. Guide blocks 31 and a spring, Fig. 2 (not shown) serve to guide the arm and hold it in frictional contact with roller 15. In a modification an electric motor drives the pinion 16.

Abstract: 1362880 Laser range finder ALLMANNA SVENSKA ELEKTRISKA AB 10 Dec 1971 [11 Dec 1970] 57433/71 Heading H4D In a pulse laser cloud-height finder the echo signal 13 is passed through a range gate 17, opened at a period T1 and for a duration t1 representing the range increment being investigated, and a range gate 18, opened at a period T2 during which no cloud echo is expected. Gate 17 thus passes any cloud echo signal present, together with noise during said investigated range increment, to an integrator 23. Gate 18 passes a noise signal which is also integrated at 24. The integrated noise signal is compared with, e.g. substracted from, the integrated echo and noise signal at 25, to produce a noise free echo signal. The level sensor 26 detects a meaningful echo signal at a time T3, occurring after many pulse repetition periods.

Abstract: 1339735 Treating waste liquid ECODYNE CORP 11 Dec 1970 [30 Jan 1970] 58971/70 Heading C1C [Also in Division B1] Liquid containing suspended solids of activated sludge is delivered to a tank 10 in which the liquid is subjected to aeration and filtration. The tank is divided by a vertical filter screen 14 into inlet compartment 16 with inlet duet 20 and filtered-liquid compartment 18 with outlet 22. Incoming liquid is aerated and given a tumbling motion by air from nozzles 28 and at the same time is subjected to a difference of head between chambers 16 and 18. The result is that the liquid arrives at the screen with a directional component across the screen surface and a directional component through the screen. The screen openings are larger than the majority of the suspended solids but because of the angle at which the liquid arrives at the screen, a coating of the solids builds up on the screen surface and subsequent filtration is through this coating as well as the screen. Compartment 18 is narrower at its base than at its top to concentrate any solids which pass the screen and these are returned to compartment 16 by pipe 30 and pump 32. Specified screen materials are stainless stee], aluminium, alloys and polymers; the screen being woven and suitably having openings of 10-100 microns. Figs. 2 and 3 (not shown) illustrate apparatus wherein a plurality of screens and aeration chambers are provided in parallel.
