Title: Improvements in means for mounting instruments or other small mechanisms in casings
IPC: G12B9/08
Filed: 1940-07-13
Abstract: 543,257. Indicating apparatus. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and DAVIS, W. O. July 13, 1940, No. 11679. [Class 106 (iv)] A mounting or support for an instrument mechanism in a casing comprises means for holding the mechanism fixed in a plane in relation to a part of the casing and wherein the mechanism contacts rigidly with the casing at two positions in said plane and resilient means to hold the mechanism against the casing at the contact points and to prevent riding of the mechanism. The invention is shown applied to an altimeter with its mechanism rotatably mounted in a supporting plate 10, Figs. 1 and 2, with a gear wheel 12 thereon meshing, through an idler pinion 13 with a pinion connected to an adjusting knob. The supporting plate 10 is of triangular form with rounded corners 14, 15 and a rounded or flattened corner 16 and fits loosely into three grooves 17 in the wall of the casing. To facilitate assembly the rear wall 18 of each groove is made longer than the front wall and the front walls differ in length. The corners 14, 15 are adapted to maintain line contact with the casing. The corner 16 is formed with a transverse slot 20 and a corresponding slot is provided in the casing for the reception of a leaf spring 22 so as to prevent rotation of the supporting plate. The leaf spring 22 is of T-shape and has its arms 23 bearing on top of the front wall of the groove so as to press the corners 14, 15 into rigid contact with the inner wall of the casing but free to move against the action of the arms 23. Springs 24 at the corners press the supporting plate against the rear walls 18 of the grooves. In a modification, Fig. 3 (not shown) the leaf spring 22 is replaced by a wire spring in the plane of the supporting plate and a pin on the casing is held between the edge of the plate and a spring member secured thereon. In another modification, Fig. 7 (not shown) the supporting plate is pressed against the front walls of the grooves the upper groove being bevelled to receive a correspondingly shaped spring to press the plate on to the lower grooves and to prevent its rotation. In the form shown in Fig. 10, the supporting plate 10 is held against simple abutments 32 by means of an off centre and inclined spring 33. A stop pin 34 prevents rotary movement of the plate.

IPC: B62K19/20
Filed: 1938-04-19
Abstract: 513,749. Soldering and brazing. NSU-DRAD VEREINIGTE FAHRZEUGWERKE AKT.- GES. April 19, 1938, No. 11771. Convention date, April 17, 1937. [Class 83 (iv)] Joints between sockets d and inserted tubes for the frames of pedal or motor cycles, are made by inserting a disc a of solder and flex between the end of the inserted tube b and either the wall of the opposite tube c, Fig. 1 or the base of the socket d in the crank bracket bars, Fig. 3, and heating so that the solder flows into .the gap between the tube or tubes and the socket by capillary action. Brazing may be effected by heating by a flame, or in a furnace or liquid bath. The disc of solder may be stamped out to ring form to reduce the amount of solder. For a tube joint in bicycles 3 grams of solder only is necessary.

Title: Improvements in the manufacture of water gas
IPC: C10J3/00
Filed: 1933-04-22
Abstract: 400,857. Water-gas plant ; liquidseal valves. POWER-GAS CORPORATION, Ltd., RAMBUSH, N. E., and BALLINGALL, J. M., Parkfield Works, Stockton-on-Tees. April 22, 1933, No. 11780. [Class 55 (i).] In the production of water gas employing up and down runs, the supply of steam and the consequent production of gas is stopped before the gas valves change-over is commenced, and started again when the change-over of the valves is completed. Steam is supplied from a pipe 10 to steam valves 16, 17 used in the downrun and up-run respectively, the water gas from the generator 1 passing either by pipe 13, or through a heat recuperator 2 and waste heat boiler 3 by pipe 12 to a valve chamber 7, from which it is led by pipe 11 to a washer 4 and outlet 18. Water is continuously supplied to the valve chamber and flows through pipe 14 to a dust catcher 9 and overflow pipe 15, which leads to the gas cooler 4, and which maintains the level 2 just below the tops of the inlets 12, 13, which are in turn sealed by hoods 19, 20 mounted on racks 26, 30 engaging with pinions 24, 25 at the ends of a shaft 21. Stops 27, 38 engage with levers 29, 31, and open steam valves 17, 16 against the action of hydraulic pistons in cylinders 28, 32. In a change-over from up-run to down-run, the first five inches upward movement of the hood 20 and of the stop 27 closes steam valve 17 without closing outlets 12, 11, after ten inches the bottom of hood 19 touches the water level and closes outlet 12, from ten to forty inches travel both steam valves are shut and gas inlets sealed. From forty to forty-five inches, gas inlet 13 opens, and at forty-five stop 38 opens steam valve 16 for a down-run. The shaft 21 may be operated by a rack 33 from a hydraulic cylinder 34, but may be operated by a handwheel and if springs or weights be used instead of hydraulic cylinders 28, 32, hydraulic operation may be dispensed with. In a modification, Fig. 3, an hydraulic piston 43 moves a combined seal pot 39 and hood 19, which alternately close the inlets 12, 13, water being sprayed by a pipe 40 against the wall of the inlet 12 and overflowing into the sump 42.

Title: Improvements in or relating to Centrifugal Separators.
Inventor: STURGEON ROBERT ALEXANDER
IPC: B04B11/04
Filed: 1918-07-19
Abstract: 130,128. Sturgeon, R. A. July 19, 1918. Density separators separating solids from liquids. A piston B forms an end wall of the annular separating chamber and by its axial movement during the continued rotation of the apparatus the solid substances are compressed and expelled. One other wall of the chamber, preferably the inner wall F, is perforated to constitute a strainer through which liquid passes during the compression of the solids. Free egress for the liquid during the centrifugal separation is provided by large openings F<1>, and these are closed in the first part of the movement of the piston. Feed takes place by way of the pipes G, and a gap between the end of the conical inner member and the piston : the gap is closed when the piston moves up to the inner member prior to pushing it along axially. Towards the end of the stroke the solids upon the piston engage the end wall A<1> and move it away from its seating in opposition to the pressure of centrifugal arms A<3>. The solids are then expelled centrifugally, and the further movement of the piston is prevented by means of a rod which opens an escape valve H'.

Filed: 1934-04-23
Abstract: 436,667. Variable-speed gearing. WHARTON, W., The Gables, Kendal, Westmorland. April 23, 1934, Nos. 12151/34 and 7161/35. [Class 80 (ii)] [See also Group XXIX] A variable-speed gear comprises two epicyclic trains having a common casing, one of which trains acts as an ordinary driving train, while the other has a variable fluid or friction coupling arranged between two of its elements to produce the reaction for the driving train. In the form shown in Fig. 1, the driving shaft 9 carries a sun-wheel 3 gearing with planets 5, which with integral stepped planets 5<1> are rotatable on spindles 12 in a rotatable casing 1. The planets 5<1> mesh with a sun 4 fixed on the driven shaft 10. The spindles 12 also loosely carry stepped planets 8, 8<1> which mesh respectively with a further sun-wheel 6 fixed on the driven shaft 10 and with a sun-wheel 7 fixed to a sleeve 11 connected to the driven shaft through the variable resistance coupling. There is a forward drive on the sun 4, and as the sleeve 11 tends to rotate faster than the shaft 10, a forward drive is transmitted through the coupling, reaction being obtained from the sun 6. In the form shown in Fig. 2, the driving shaft 21 carries a sun-wheel 70 gearing with planets 72 mounted on a carrier 74 connected through a reversing train 75, 76, 80 to the driven shaft 23. The annulus 71 engaging the planets 72 acts as a carrier for stepped planets 31, 31<1> respectively engaging a further sun-wheel 28 fixed on the driving shaft 21 and a sun-wheel 29 on a sleeve 30 carrying bevel planets 34 engaging a bevel wheel 35 on the driving shaft and a bevel 36 on a sleeve 37 carrying the vanes 38 of an adjustable hydraulic coupling whose casing 25 is secured to the driving shaft 21. Owing to the bevel gearing 34, 35, 36 the vanes 38 will, in the absence of fluid resistance, rotate relatively to the casing 25 at twice the relative velocity between the sleeve 30 and shaft 21. The vanes 38 of the coupling are pivoted on arms 39, Fig. 4, radiating from the sleeve 37 and are urged outwards towards the vanes 26 on the casing 25 by plungers 50 acting through links 51 and cranks 38<1>. The plungers 50 are forced outwardly by liquid pressure entering the cylinders 49 from a space 48, in which pressure is produced by pumps 40 operated by an eccentric 43 on the sleeve 30. The pumps 40 supply liquid to the space 48 through non-return valves 47. A roller freewheel clutch 53, 54, 55 has its inner member 55 connected through a sleeve 56 to the friction disc 59 of a friction clutch whose presser plate 60 may be disengaged by pivoted levers 62 operated by a sliding collar 67. When the clutch is engaged the reaction on the carrier 74 is taken through the freewheel clutch on to the gear casing. A fixed or variable interposed between the sun-wheel 29 and the hydraulic coupling. Specification 192,244, [Class 69 (ii)], is referred to in the first Provisional Specification.
