Patent GB-1024199-A (GB)
Title: Electrodes for galvanic cells and accumulators and processes for their production
IPC: H01M4/02
Filed: 1963-03-27
Abstract: <PICT:1024199/C6-C7/1> An electrode for accumulators is made by impregnating a lightweight porous skeleton material e.g. of plastic or spun glass, with a metal oxide as active mass formed anodically in an electrolyte.  For example, two layers of sintered polyethylene are united with a central leaf of lead foil which has slits or recesses to anchor and unite the two plastic layers.  This is immersed as anode in an electrolyte consisting of alkaline lead plumbite or an ammoniacal solution of silver, when lead or silver oxide particles 6 are formed between the sintered plastic particles 5.  The lead oxide may be converted to the dioxide by treatment with H2So4 containing anions e.g. nitrate, acetate, chlorate, to form soluble lead salts, which will also convert the lead foil 2.  This is preferably masked at least partly, with lacquer to maintain the lead structure in metallic form.  As an alternative to lead, nickel or copper may be precipitated on the porous skeleton to render it conductive, and after impregnation with lead oxide the Ni or Cu is dissolved out. Preferably the electrolyte contains sodium nitrate or sulphite to suppress oxygen generation at the anode.  Electrodes so produced have a capacity of 3 to 4.5 amp. hrs. per sq. dm.

Patent GB-474388-A (GB)
Title: Improvements in or relating to electrical frequency dividing circuit arrangements
IPC: H03B19/12
Filed: 1936-04-29
Abstract: 474,388. Valve circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and BELL, D. A. April 29, 1936, No. 12218. [Class 40 (v)] In a frequency-divider capable of dividing by any even number there is no output in the absence of input. The input frequency is applied through terminals 11 to the grids 5, 6 in parallel, while the subharmonic frequency is superimposed on the same grids by way of cross coupling condensers 15, 16, connected across a circuit 18 tuned to the subharmonic frequency. The grids 5, 6 are so biassed that no anode current flows in a valve unless both the component voltages on the grid of that valve are positive ; and such a coincidence of positive voltages is shown to occur in each valve once per cycle of the subharmonic frequency. The cross coupling is of such magnitude that it is insufficient to cause self-oscillation. The output circuit, having output terminals 21, is balanced with respect to the input circuit and is consequently freed from the input frequency.

Title: Improvements in or relating to hydraulic presses
IPC: B21D24/14
Filed: 1944-06-28
Abstract: 592,037. Hydraulic presses. FITZPATRICK, H. D. (Clearing Machine Corporation). June 28, 1944, No. 12280. [Class 69 (ii)] [Also in Group XXII] An hydraulic press comprises two movable slides, a source of fluid pressure supply common to both of the slides but directed individually to each of the slides to operate thereon, means whereby a predetermined fluid pressure may, be established on the respective slides, and a piston and cylinder unit one of the elements of which is connected to and movable with each of the slides, the unit operating to transfer fluid from a supply to the fluid pressureoperating means of one of the slides for compensating leakage of the fluid pressure in the means for establishing the predetermined pressure which is maintained against augmentation for a predetermined period in the retraction period of the other slide. The work-holding slide 14 and the tool slide 15 are slidably connected by a rod 23. A pump 40 delivers fluid through a four-way valve 46 and a pipe 48 to the top of a piston 21 connected to the inner slide 15 to lower both this slide and the con, nected outer slide until the latter strikes the work ; the inner slide continues to descend against pressure in cylinders 31 on the outer slide coacting with pistons on the inner slide, these cylinders discharging through passages to the top of pistons 18 connected to the outer slide and moving in fixed cylinders 20 and so maintaining a pressure on the holding slide which pressure is limited by relief valves 78 in valve casings 52 of the supply pipes 54 of the cylinders 20 which draw from a tank 35 through pre-fill valves 39 during the descent of the outer slide. During this descent, liquid from around the lower part of piston 21 discharges through a pipe 49 and valve 46 to the main tank, while a pre-fill valve 36 and pre-fill valves 39 open to admit liquid from the tank 35 to the cylinders 20, 22. The inner slide continues to move down until it operates a switch 96 to reverse the valve 46 and a three-way valve 51 through solenoids. The pump then discharges through the pipe 49 to ra,ise the tool slide and through the valve 51 to increase pressure on the work-holding pistons, this pressure finally opening the relief valve 78 to close a valve shutting off the supply to the work-holding pistons. With this valve closed, the pressure will rise to operate a switch 53a reversing the valve 46. The valves are operated by pressure from a pilot pump 55 when the control valves are operated by the solenoids.

Abstract: 727,255. Aircraft controls. FAIREY AVIATION CO., Ltd. June 23, 1953 [May 20, 1952], No. 12760/52. Class 4. [Also in Group XXIX] An aircraft having one or more jet-propulsion units and fluid pressure operated thrust direction control means controlled by an operating member in common with control surfaces, is characterized by emergency means responsive to complete or partial failure of the fluid pressure supply for centralizing the thrust direction control means. The embodiment described (Fig. 1) has four jet engines, an upper, a lower, a left and a right engine. The two former are rotatable about vertical axes with the rudder, and the latter about horizontal axes with the elevators. Provision is also made for making the aircraft roll. A lever A pivoted at B has link rods D' slidable in studs A<SP>1</SP> and limited in motion one way by nuts D<SP>3</SP>. These link rods D<SP>2</SP> are pivoted to a lever D operated by control mechanism through rod D<SP>1</SP>. Pivot B is controlled by a jack C, and in the normal position of Fig. 1 lever A is urged to abut nuts D<SP>3</SP> so that lever A moves with lever D without lost motion. Two further links F<SP>1</SP>, connected to lever F, slide in studs A<SP>2</SP> on lever A, and in the normal position lever A abuts nuts f<SP>3</SP> so that lever F rotates with lever A without lost motion. Lever F controls through links or chains a lever G<SP>1</SP> operating a fluid pressure jack G<SP>2</SP> to control the direction of jet thrust. A piston K<SP>1</SP> is subjected on one hand to the pressure in the supply line to the main hydraulic accumulator (not shown) through pipe M, and on the other to the pressure of an emergency accumulator (not shown) through pipe L. The effective areas of the piston are chosen so that the piston is moved when the supply pressure to the main accumulator falls below a certain value. The movement of piston K<SP>1</SP> changes a changeover valve J, admitting fluid pressure to jack C, which draws lever A to the right of the Figure into abutment with two fixed rollers H which square the lever. Lever A also abuts the nuts F<SP>2</SP> without lost motion, to square lever F and centre the jet thrust. At the same time lever A is withdrawn from nuts D<SP>3</SP>, allowing lever D to pivot with the control surfaces unhindered. Pipes J' and J<SP>2</SP> operate the jacks C of the other jet engines. The changeover valve is fed through non-return valves L<SP>1</SP>, N<SP>1</SP> from the main and emergency accumulators, drawing fluid from whichever has the higher pressure. A lever R operated by movement of pivot B may also serve to change certain fluid pressure services, e.g. all except aerodynamic controls, from the main accumulator to the emergency accumulator. A microswitch Q is actuable with the changeover valve J to give a visible warning to the pilot. A manual changeover control may override the automatic control.
