Title: Improvements in percutaneously activated controls for implantable cardiac pacemakers
IPC: A61N1/375
Filed: 1963-10-18
Abstract: 1,064,376. Cardiac pacemakers. WILSON GREATBATCH, Inc. Oct. 18 1963 [Oct. 18, 1962], No. 41187/63. Heading A5R. An implantable cardiac pacemaker or electrical pulse generating device for stimulation of the heart, has percutaneously actuated pulse rate and amplitude controls. As shown, the controls comprise variable potentiometers 2. Each control comprises a worm wheel 4 to which is connected a potentionmeter element (23') (Fig. 7, not shown) which is driven across resistance (23) upon rotation of wheel 4 by worm 5. Worm 5 has head 7 in which is engaged adaptor 10 having recess 12, which adaptor is surrounded by sleeve 16 having recess 18. Recesses 12 and 18 are filled with, e.g. silicone grease and the controls are enclosed in puncturable material (e.g. silicone rubber) which is nontoxic and compatible with the human body. To alter a control when the pacemaker is implanted in the body, the position of the desired knob 22 is determined by touch, and a needle (14) (Fig. 3, not shown) is inserted through the skin and guided into recess 12 by sleeve 16. On rotating the needle (14) the adaptor 10 and worm 5 are rotated and thus wheel 4 is rotated to alter the position of potentiometer element (23') along the resistance (23).

Title: Combustion apparatus for gas turbine engines
IPC: F23R3/28
Filed: 1972-09-07
Abstract: 1427146 Gas turbine engine combustion apparatus ROLLS-ROYCE (1971) Ltd 28 Aug 1973 [7 Sept 1972] 41504/72 Heading F1L The invention relates to combustion equipment for gas turbine engines, the equipment shown in Fig. 2 comprising a series of tubular flame tubes 16 disposed within an annular air space defined by annular walls 17, 18. Each flame tube comprises a dome member 20 at the centre of which is mounted a fuel burner which comprises a tube member 24 which defines with an inner member 28, an annular air passage 29 which is divided by a series of radial vanes 29, Fig. 3 into a series of axially-extending air/fuel passages 30. Fuel is supplied through an injector 32 having a head 31 formed with apertures 33, one for each passage 30. A fuel impingement ring member 34 is disposed around the injector head. The tube member 24 is mounted within a shroud member 23 which is formed with air inlet openings 26 through which air passes to an annular space defined between the shroud and the tube member. Air enters the tube member 24 through a convergent inlet 25 defined by the shroud member. A deflector member 37 is mounted at the downstream end of the tube member 24 so as to define a convergent annular outlet 41 through which air/fuel mixture discharges radially as indicated by arrows 99. The mixture is ignited and forms a toroidal vortex 100 adjacent the end dome 20. Further air enters the flame tube through radial inlets 44 and forms a second toroidal vortex 200 of opposite hand to the first vortex. The invention is shown applied to an annular flame tube in Fig. 5 (not shown), there being a series of part-cylindrical tube members (55) corresponding to the tube member 24, disposed adjacent the inner annular wall of the flame tube; each member has associated therewith a fuel injector (58) and a deflector member (56); the end wall of the flame tube is shaped to define a shroud member (60) corresponding to the shroud member 23.

Abstract: 952,126. Air cushion vehicles. WESTLAND AIRCRAFT Ltd. Nov. 13, 1962 [Nov. 21, 1961; Jan. 26, 1962; Feb. 3, 1962], Nos. 41542/61, 3148/62 and 4254/62. Heading B7K. An air cushion vehicle has a main gas system discharging pressurized gas from the bottom of side, end, or peripheral downwardly extending walls or skirting to generate and contain the gas cushion, and downwardly extending walls or keels partitioning the cushion area, pressurized gas being discharged from the bottom of such walls or keels, so as to cause, during pitching or rolling, a pressure differential within the cushion area to produce a righting moment on the vehicle, at least the parts of the walls or skirting and the partitioning walls or keels which are likely to be subject to wave or obstacle impact being of flexible construction. Fig. 1 is a perspective view from above of peripheral skirting 1, having inner and outer flexible walls 2, 3 of rubberized material reinforced by canvas or nylon mesh. Diaphragms 4 divide and shape the skirting and form jet nozzles 5, fed from gas ducts surrounding the main platform (not shown) of the vehicle. Flexible keels 8 and 9, of construction similar to the skirting, also depend from the platform, and discharge stabilizing jets downwardly. The depth of the keels should be not less than the depth of the skirting less half the ground clearance during hover, nor more than the depth of the skirting, plus the ground clearance. During pitching or rolling, the pressure in the various compartments 20 is varied by the stabilizing jets from the keels in the sense to right the vehicle. Gaps 21 between the keels and between the keels and skirting determine the degree of damping in pitch and roll, and this may be varied by inflatable conical members 11, one being shown in Fig. 4, located between the inner skirting wall 2 and a keel 9, and attached to the former. The pressure in the member 11, and hence the gap between the keel and the member, is varied by control of an individual gas supply, or by inflating the member through an aperture 12 from the gas supply to the nozzles 5. A further vehicle is described, Fig. 5 (not shown), in which the side parts of the peripheral skirting are rigid, and the forward and rear parts are flexible. A central fore-and-aft extending stabilizing keel is flexible only at its forward part. According to the first Provisional Specification, the keels may be of H, X or Y formation seen in plan.

Abstract: 1,272,811. Dosimeter reader. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. Aug. 20, 1969 [Aug.20, 1968(4)], No.41553/69. Heading G1A. In a thermoluminescent dosimeter reader the dosimeter is heated by directing heated gas against it. The gas may be air or oxygen and its temperature may be retroactively controlled. The dosimeter to be read may be moved into an enclosure containing the reader on a slide which may carry at its leading end a radioactive source and scintillator for calibration purposes. The hot gas may be directed down on to the dosimeter to be read, and a photo-multiplier may be housed beneath it to receive the luminescence through an optical system. The hot gas may be circulated for re-use and may be applied for a controlled time. A modification has a separate heater for pre-heating to a lower temperature to eliminate unwanted luminescence. The detector output may be integrated.

Abstract: 864,177. De-sulphiting fruit juices. VEDEL, J. M. A. Dec. 29, 1958, No. 41864/58. Class 49. In de-sulphiting fruit juices, sulphur dioxide is first eliminated by fixing it with an absorbent substance, the naturally occurring aromatic compounds separated from the sulphur dioxide after its absorption are condensed, and the condensed aromatic compounds are restored to the fruit juice under treatment. Heated fruit juice is de-sulphited in a tank 3 by an inert gas circulated by a pump 18 to a bubbler 20; the sulphur dioxide driven off is fixed by an absorbent substance in a vessel 5 while aromatic compounds are condensed in condensers 7, 10, and incorporated in the de-sulphited juice flowing in the pipe 12.

Abstract: 427,292. Seaming. WAGNER, G., 292, Podbielskistrasse, Hanover, Germany. Nov. 9, 1934, No. 32293. Convention date, Nov. 10, 1933. [Class 83 (iv)] Seamed joints.-A rubber ring to be introduced into the joint during the seaming of a lid to a can body is placed loosely around the can and is pressed into the rim of the lid immediately before seaming by an axially movable member. A can 20 is supported on a table 19 and moved upwardly against a driven member for rotation, when it is seamed by rolls 2, 3 brought in turn against the work by a handle 4. A member 6 pivotally mounted on the handle 4 strikes a roller 9 to cause a two-armed lever 7, 8 to pivot about a horizontal pin 10 and upon its end 11 engaging a projection 12, to raise a rod 14. A roller 17 on the rod presses the rubber ring 21, Fig. 4, into the rim of the lid, while a cam 16 lifts the tearing-piece 211 from the can to allow the roller to operate, a further guiding-surface then again laying the member 21<1> against the can wall to allow the seaming-rollers to operate. In a modification, especially for non-circular cans, and wherein the can is not rotated, the ring is pressed into the seam by resilient fingers 29, Fig. 7, on a vertically slidable head 28 which is controlled through a toggle linkage system from the pedal 25 which raises and lowers the can support 19.
