Patent GB-569941-A (GB)
Title: Dividing engines
Filed: 1942-11-13
Abstract: 569,941. Dividing-engines. KING- STON-UPON-HULL, CORPORATION OF THE CITY AND COUNTY BOROUGH OF, and MELL, R. E. Nov. 13, 1942, No. 16050. [Class 97 (iii)] Relates to a dividing-engine for marking discs &c. especially for use in carrying out stroboscopic tests, for instance on fluid flow or electric meters and consists in applying a series of markings to the disc &c. by an electrically-actuated marking device supplied with a predetermined succession of impulses which may be varied in number according to the spacing of markings desired. As shown, the disc 4 to be marked is secured on a carrier 5 around which a graduated arm 8 may be rotated either manually or by an electric motor. A slide 9 carries a wheel 10 resting on the supporting table 6. As the arm 8 is rotated, the wheel 10 is driven by contact with the table and causes a star-wheel 12 periodically to open and close the circuit of an electromagnet 17 which causes a cutter 15 to strike the edge of the disc 4 momentarily, to produce the markings. The cutter.is mounted with lateral resiliency to avoid drag during a marking action as the arm 8 rotates. The number of markings produced during a rotation of the arm is determined by the radial setting of the slide 9 against graduations on the arm. The arm may be temporarily secured at its starting point by a spring-pressed plunger 30 and the correctness of the setting of the slide 9 may be tested by setting a mark on the wheel 10 into coincidence with a line 25 on the table, and then moving the arm through a complete revolution and comprising the positions of the two marks. The cutter may be arranged to mark the face of the disc instead of the edge. Instead of the cutter rotating round the disc, the disc may be arranged to rotate. In a modification wherein the disc rotates, the wheel 10 is adjustable over a coned surface driven in unison with the disc. Specification 569,940 is referred to.

Patent GB-357206-A (GB)
Title: Improvements in and relating to the production of liquid hydrocarbons from solid fuels
IPC: C07C1/04
Filed: 1930-05-30
Abstract: <PICT:0357206/III/1> <PICT:0357206/III/2> Liquid hydrocarbons, more especially for use as fuels, are obtained by subjecting the gases obtained by the distillation of solid fuels together with a mixture of carbon monoxide and hydrogen simultaneously to the action of a high-potential electrostatic field and of ultra-violet rays. According to the arrangement described, solid fuel is fed from a hopper b into a chamber c arranged in the path of the hot gases arising from a grate e, so that its temperature is about 500 DEG  C. Low-temperature distillation takes place, and the resulting gases pass out by the pipe c<1>.  The chamber c is extended downwards by a pipe d maintained at a temperature of 900 DEG  C., and into which the solid fuel falls after passing through chamber c. High-temperature distillation occurs, and the products are removed by a pipe d<1>. Around the grate e is a tube f, preferably of iron, which is fed with water and raised to a sufficiently high temperature to dissociate the water; oxygen combining with the metal of the tube, and hydrogen passing out and mixing with the gases obtained from the solid fuel in a series of pipes, such as j<1> which are arranged round the chambers c, d so that pipes j<1>, j<2> are heated to about 600 DEG  C. and the remaining two to 300 DEG  C., screens being used if required to prevent too rapid heating.  Passage of the fuel down the central chamber is assisted by a rotating rod i.  The semi-coke obtained in the chambers c, d is burnt on the grate e as in a gas-producer, and the gas obtained is drawn out through the top of the apparatus and through a dust extractor k<1> by a fan k<2>.  The gas then passes by a pipe k to mix with the other gases in pipe j<1>, any excess being returned to the furnace by a branch pipe k<3>.  In one of the pipes j<1>..j<4> there is arranged, as shown in Fig. 2, an electrode m, connected to a source n of high potential, e.g. 80000 to 100,000 volts, and also a source o of ultra-violet rays, one of the end walls l<1>, l<2> of the tube being made of material permeable to the rays, such as fused quartz.  The stream of gas and the ultra-violet rays are preferably arranged to travel in opposite directions.  The products obtained are condensed in a cooler arranged at the exit of the series of tubes.

Title: Improvements in or relating to stacking and unstacking barrels, packages and the like
IPC: B65G67/00
Filed: 1922-06-19
Abstract: 204,370. Spencer, H. E. June 19, 1922. Hoists with guided platforms.-In a stacking- machine for barrels, &c. of the kind in which the guides for the platform leave between them a clear through-way on two opposite sides of the platform, a control gear for the driving mechanism is set to neutral position when the platform comes into contact with a stop mounted on an unloading table which can be set at any height, and, if desired, the control gear may move automatically to reverse the drive and lower the platform after a period of delay. The framework 10, Fig. 1, has guides 12 on two opposite sides and the other sides left unobstructed so that articles may be loaded on to the platform 20 by a runway 16 and unloaded at the opposite side by a table 17. Triangular members 19 attached to the platform 20 engage with the guides 12 and are suspended from chains 33 passed over wheels 32 and attached to counter-weights 34. The shaft 30, on which the wheels 32 are mounted, is driven through worm gearing 31 by a shaft 28, Fig. 3, loosely carrying a pair of opposed bevel gears 26, 27, which mesh with a. single bevel gear 25 on the shaft of the motor 23. Either of the gears 26, 27 can be coupled to the shaft 28 by a clutch 29 which can also take up a neutral position in which both gears are free. The clutch is actuated by rocking a shaft 36 either manually by a lever 43, Fig. 5, or automatically when a cam on the platform 20 turns an arm 45 mounted on a vertical shaft 47 which is operatively connected with the shaft 36, The arm 45 is slidable on the shaft 47 and is connected to the table 17 which is supported by chains 52 passing over wheels 53 and is held in any position by clamping screws 54. If it is desired automatically to effect the return of the platform, an inclined guideway 7, Fig. 5, is mounted on the shaft 36 in which slides a weight 73, the inclination of the guideway being increased as the weight slides down until the shaft 36 has been turned sufficiently to put the clutch in position to effect the lowering of the platform. The guideway rests on the legs of a yoke 62, each of which has a low and high portion, and which are arranged so that the high portion of one leg is opposite the low portion of the other. The yoke is slidably mounted in a bracket 61 and is moved by a hand lever 67 to effect the setting of the guideway. At the lower limit of its travel a cam 81 on the platform encounters a roller 82, Fig. 5, and rocks the shaft 36 to put the clutch in neutral position. The articles are discharged automaticon to the table 17 by the tilting of arms 83 pivoted to the platform caused by contact with cams 90 on the table.

Abstract: 561,658. Electric motors. SCHWARZ, B., MOSSAY, P. R., and MOSSAY. P. A. H. Nov. 27, 1942, No. 16895. [Clase 35] [Also in Group XXII] A rotor for an A.C. motor having a cage starting winding of low reactance and a pitched working winding of higher reactance, such as described in Specification 494,660, is made by casting said windings in situ. The laminations CP may have circular holes a, b, c for the conductors and radial slots g, g<SP>1</SP>, which do not, however, connect the holes but are stopped by bridges s<SP>1</SP>, s<SP>2</SP>, s<SP>3</SP>, The end plates EP have holes corresponding to a, b, c but no slots. The mould cavity is completed by end plates (not shown), one having a groove to mould a ring r<SP>1</SP> connecting all the conductors cast in holes a., b, c, and the other to mould a ring r connecting the conductors a and a series of links e, Fig. 5, each connecting one conductor b to one conductor c. Aluminium or other metal cast under pressure into such a mould fills all the holes and slots except the slots g but does not connect the low reactance cage winding a, r with the higher reactance working winding b, e, c except at the common ring r<SP>1</SP> and, if desired, this ring may be cut into two rings or two separate rings may be formed in casting. If this is done it may be carried out in two stages using two aluminium alloys differing in specific resistance. Fig. 6 shows a modified arrangement of holes and slots. The reactance and resistance of the windings can be varied by altering the number of poles or pitch of the working winding the size of the holes and slots and the position and number of the bridges, e.g. bridges s<SP>2</SP>, Fig. 1, may be omitted thus causing the metal to flow into the slots g. The working winding may have links, as at e, Fig. 5, at both ends or the holes b, c could all be arranged at the same distance from the centre.

Abstract: 687,788. Universal joints. SILENTBLOC, Ltd., and GRAHAM, S. J. G. July 6, 1951 [July 6, 1950], No. 16912/50. Class 80 (ii). [Also in Group XXXII] In a coupling of the kind in which an intermediate member is connected by rubber bushings to the driving and driven members the parts of the bushings adjacent to a plane through the axes of the coupling and the bushing are formed with longitudinal slots or holes the other parts being relatively solid. Thus torque is transmitted, and relative angular displacement of the coupling parts resisted, by the relatively solid parts of the bushing acting in compression while angular mis-alignment is readily accommodated. In the embodiment shown rubber bushes D' are disposed between metal tubes D, D' and are either under initial compression or are bonded to the tubes. The outer tubes are carried in an intermediate member C and diametrically opposite inner tubes engage pins E on the driving and driven members B and A, Fig. 1 (not shown). Arcuate slots D' extend longitudinally through the bushes and may subtend angles of between approximately 90 degrees and 150 degrees at the centre of the bush.

Abstract: 386,647. Internal-expanding shoebrakes. CROCKETT, R. A., 29, Kremlin Drive, Stoneycroft, Liverpool. June 11, 1931, No. 16954. [Class 103 (i).] In an internalexpanding shoebrake an arm or lever within the brake-drum bears at a point intermediate its ends on one shoe and acts as a lever of the second order for forcing the shoe against the brake-drum while it also acts as a lever of the first order for forcing, directly or through the intermediary of an additional lever, a second shoe against the drum. In one construction two shoes 28, 29, Fig. 5, are moved about fixed pivots 30, 31 by a cam 34 or hydraulic plunger operating tangentially on one end of a lever 32, freely pivoted to a lever 33 having a fixed pivot 35, the braking force being transmitted to the shoes radially by rollers 37, 38. In a modification the lever 32 is pivoted to a short lever mounted on a fixed pivot, the lever 33 abutting the short lever. In another construction braking force is transmitted by a cam 9, Fig. 1, radially through a lever 7 and roller 8 to a fixedly pivoted shoe 2 and tangentially through the lever 7 to a shoe 3 fixedly and adjustably pivoted at 5, the lever 7 being freely pivoted to the shoe 3. One of the shoes, for example the shoe 3, Fig. 1, may have a limited amount of peripheral freedom so that it may be selfenergizing in both directions of rotation of the brake drum. The levers are preferably curved stampings between which the rollers are journalled while bosses or the like provide bearings for the pivot pins. A block may be secured between the ends of a pair of stampings for engagement by a cam.
