Filed: 1918-12-10
Abstract: 141,400. Last, J. Dec. 10, 1918. Ellipsographs.-An ellipsograph comprises a Hooke's joint A constrained to move in a circle inclined to the plane of the ellipse to be drawn, and carrying a pen, pencil, &c. h maintained perpendicular to the plane of the ellipse. The instrument is constructed with three legs e<2>, e<3>, e<4>, the legs e<2>, e<3> carrying a semicircular slotted archpart E on which is adjustably mounted a rotatable spindle C secured by a screw d<2> and nut d'. A plate B is secured to the spindle C and carries a screwed rod b<2> on which is mounted a slide b<1> carrying one axis of the joint A. A stem f<1> depends from the joint A and slides within a member f<11> carrying the pen h, a pin f<2> on it engaging a slot f<3> in the member f<11>. Links j, k extend between the member f<11> and the leg e<2> so as to keep the member f<11> vertical during its movements, and a weight m presses the pen on to the paper against the action of a spring l. When the instrument is to be used, the points of the legs c<2>, e<3> are placed on the minor axis and the point of the leg e<4> on the major axis. The spindle C is then turned so that the axis of the rod b<2> is horizontal, and the rod is rotated until the pen is at one end of the major axis. The spindle is then turned so that the pen is on the minor axis, and the position of the spindle C with relation to the slot in the arch E is adjusted so that the pen is at one end of the minor axis. The spindle C is then rotated to cause the pen to describe the ellipse.

Title: Improvements relating to a photo electronic system
Inventor: BRACEY RONALD JOHN
IPC: G01F23/292
Filed: 1958-06-26
Abstract: 857,877. Photo-electric indicating devices. BAIRD & TATLOCK (LONDON) Ltd. June 26, 1959 [June 26, 1958], No. 20559/59. Class 40(3). The invention relates broadly to devices indicating which of two fluids having different refractive indices occupies a given position in a circular tube transparent to an investigating radiation. The embodiment described is concerned with the determination of the level of a liquid in a burette in automatic titration apparatus. In this, radiation from a light source 2 is formed into a collimated beam by lens 3 and directed by mask 4 on to transparent burette tube 1. If the tube contains air the beam becomes slightly divergent as indicated at 11 and may be made parallel again by lens 6 before being brought to a focus on photo-cell 8 by lens 7. The presence of liquid in the tube causes the light beam to be brought to a focus on an opaque strip 5 and negligible radiation is directed to cell 8. The strip 5 must be positioned in accordance with the geometry of the system and the refractive index of the liquid concerned. If its position is arranged to be on the surface of lens 6 it may be formed by etching a stripe down the lens surface and filling it with an opaque substance. The photo-electric system may be mounted to move along the length of the tube and in particular to move downwards until the liquid intercepts the beam and then stop and indicate, or record, the liquid level.

A hollow article is moulded either by the two-stage injection of rubber or synthetic plastics material into the cavity 11 between a core 18 and mould 16, the first stage injection providing inserts which support the core against twisting or bending during the second stage injection, or by a one-stage injection using metal or plastics inserts. In both cases the inserts remain as part of the finished article. In the embodiment shown, for moulding a hot water bottle, the core, supported at one end by a holder 19, is given support by a first injection at a relatively low pressure through channels 23 with pre-vulcanization or pre-gelling of the material which then surrounds the core at its end remote from holder 19. Subsequently cavity 11 is filled by injection at high pressure e.g. 1500 atmospheres, through channels 24. A suspension tab 12 is moulded whose eye is formed by a pin (13), Fig. 2 (not shown). To allow removal of waste material from channels 23, 24 the core may be horizontally split or the channels may be tapered. Alternatively, the moulding material may be injected into cavity 11 from opposite sides via channels in the mould. In a second embodiment, Figs. 3 and 4 (not shown), core (18) is held by a combined ring (14), which encircles pin (13), and support member (17). In a modification, Figs. 5 and 6 (not shown), core (18) is supported by members (20).

Filed: 1920-07-12
Abstract: 168,222. Dobson, J. July 12, 1920. Saddle supports.-In mountings for cycle saddles wherein the saddle is carried from the pillar member of the frame by two pairs of parallel legs or supports D in such manner that the cyclist can, without dismounting, move the saddle backwards and forwards, and the saddle during the movement remains substantially horizontal, the front legs carry racks J engaging with a guide H upon the pillar frame member, the racks being retained in desired position by a spring-controlled bifurcated catch K connected by a wire W to a handlever on the handle-bar adjacent the ordinary grip. A spring N tends to draw the legs forwardly so that, on releasing the catch and relieving the saddle of weight, the saddle is carried towards the front. On the other hand, by back pressure against the saddle after the catch has been released, the saddle can be brought to a backward position. As the only support required for the apparatus is the pillar member, the device is applicable to both gentlemen's and ladies' machines. According to the Provisional Specification, the hand-lever is clipped to the cycle head.

Abstract: 352,260. Screw propellers. SOC. ANON. DES ATELIERS D'AVIATION L. BREGUET and BREGUET, L., 115, Rue de la Pompe, Paris. July 12, 1930, No. 21184. [Class 114.] In automatically variable pitch screw propellers, the boss is displaceable axially on and rotatable through a small angle around the propeller shaft and the blade is connected with a projection on the shaft so that its pitch is varied automatically as the boss moves in relation to the shaft and in accordance with the ratio of the tractive effort to the driving couple of the propeller. In one form the boss 2 has a projection 13 carrying a roller 12 which is in contact with a cam face 11 on a fixed sleeve on the propeller shaft 1. The roller 11 thus communicates the drive from the shaft to the roller whilst allowing the boss the two degrees of freedom. A propeller blade 3 pivotally mounted in a socket on the boss has an arm 7 engaging at 8 with a projection 9 from the shaft whereby its pitch angle is varied as the propeller boss 2 takes up new positions. In another form the driving shaft 30 is keyed to a cylindrical member 31 upon which the boss is freely mounted. Keyed to this member are cross members 34, 35 which are coupled by rods 36, the member 34 having pins 52 which project into curved slots 51 in the pitch-adjusting arms 50 pinned to a projection on each blade root. The coupling rods 36 have pins 56 with self-adjusting ball races for driving rods 53 which at their other ends are similarly connected to pins 57 on sockets 42 carrying the blades.

Title: Process and apparatus for purifying and sterilizing swimming pool waters
IPC: C02F1/46
Filed: 1960-06-16
Abstract: <PICT:0950482/C3/1> Swimming pool water is purified by pumping it from the pool 1 through a closed circuit comprising a coarse prefilter 4 and electrolytic tank 11 to which pulsed D.C. power is applied, by which organic materials are flocculated, and are removed in a filter chamber 14, from which the clean water is treated oligo-dynamically in a silver electrode cell 16 and returned to the pool.  Preferably at the entry to the pool, the water is oxygenated in a device 18 where air is forced through a Venturi tube into the stream of water.  The electrolytic tank contains stainless steel cathodes and aluminium anodes, ions from which pass into the water and coagulate the impurities. The power supply is reversed to the electrodes from time to time, to depolarize them.  The filter chamber 14 is provided with a bell 13 surmounting the main chamber, and the water enters at the top and is jetted tangentially against the inner wall of the bell giving a centrifuging effect on the flocculated particles.  The water and suspension flow downwards through a bed of sand which is stirred up from the bottom by water fed through a by-pass connected to the inlet and ending in a jet in the bed of sand.  A coned perforated screen prevents sand particles from leaving the filter 14 at the base to enter the silver cell. The apparatus includes transformers, rectifiers, and meters with circuitry to control the process automatically.
