Title: Improvements in or relating to beer and other liquid dispensing installations
IPC: B67D1/16
Filed: 1946-10-12
Abstract: 632,171. Dispensing beer; injectors. YOUNG, G., LAING, D. T., and WALLS, J. H. Oct. 12, 1946, No. 30495. [Classes 71 and 102(ii)] Apparatus for dispensing simultaneously liquid from two different sources, e.g., " live " beer under pressure and collected overflow or " waste " beer, comprises a rotary valve member 1 with a diametral passage 5 communicating in one position of the valve with a conduit 6, 15, leading to a source of liquid under pressure, the passage 5 leading to a nozzle 7 opening into a larger axial passage 10 with which also communicates by a radial passage 8 a conduit 9 leading to the source of a second liquid. The nozzle 7 and passage 10 constitute an injector so-that as liquid is dispensed from the first source liquid from the second source is drawn in and mixed therewith, Rotation of the member 1 through 90 degrees cuts off the supply. A further rotation of 90 degrees causes one liquid only to be dispensed, the passage 8 then being blocked or communicating with a bore 14 which may be provided so that air is mixed with the issuing liquid. The invention may be applied to a counter fount of the pillar (as shown) or wall bracket type, the pillar or bracket arm being provided with the liquid supply passages 6, 9, or to wall founts. In a modification (Fig. 2, not shown) applied to a wall fount, the second liquid is led through an external pipe to an annular housing surrounding the lower part of the valve member, the passage 8 and nozzle 7 being formed in the part of the valve member within this housing. A bore similar to 14 may be provided in the housing.

Title: Improvements in Free Wheel Hubs for Cycles and the like.
Inventor: OLSEN FREDERICK JOHANNES
IPC: B62L5/00
Filed: 1919-12-05
Abstract: 136,541. Olsen, F. J. Dec. 10, 1918, [Convention date]. Back-pedalling brake and free-wheel arrangements, of the kind in which an outer hub member d, Figs. 2 and 4, has a loose split-sleeve e co-acting therewith and adapted to be expanded by a wedging-element f, shown in Fig. 5, arranged in a gap in the sleeve, are characterized by the fact that the wedge f directly engages the screwthread g of the driving-member b, Fig. 3, being thereby displaced longitudinally of the hub and carrying the loose sleeve e with it; further, the wedge f is formed with inclined surfaces or coarse teeth h which act upon corresponding faces on the split sleeve to expand the sleeve into driving or braking contact with the outer member d. As shown in Fig. 2, the parts are in the free-wheel position. On forward pedalling, the screw-thread g at first displaces the wedge f, and therefore the sleeve e, to the right into contact with a toothed ring k fixed to the hub member d. Further pedalling causes the teeth h to expand the sleeve until it makes driving contact with the hub member d. Reverse pedalling first moves the wedge and sleeve over to the left into contact with teeth on a fixed nut m, and subsequently expands the sleeve e to exert a braking-torque. A flat spring o produces a slight friction tending to move the sleeve to the left when the pedals are immovable.

Title: Improvements in moving electric signs
IPC: G09G3/00
Filed: 1924-12-19
Abstract: 249,216. Penney, A. B. Dec. 19, 1924. Stencil switches. -Relates to flashing signs of the type in which electric lamps arranged to form a uniform field are selectively illuminated under the control of a switch of the moving stencil type, so as to present the appearance of moving letters and the like. According to the invention, the stencil is formed of a series of stiff plates joined together to form a chain, the flexible contacts are mounted in grooves formed as easily detachable units, and the lamps are connected to individual fixed contacts in an insulated base member. Thus metal plates 1, Figs. 7 and 8, formed with stencil holes a, may be bent over at their sides to form flanges 2 carrying studs 3, and the plates may then be formed into a chain by means of coupling hooks 4, Fig. 1, engaging the studs. Alternatively, the plates may carry a forked lug, holding a hinge pin at each of their corners, or each plate may have along its middle line a pair of flanges 8, Fig. 15, carrying hinge pins 9. The chain of plates 1 then passes above a field of fixed terminals 12, each connected to a corresponding lamp. To prevent contact between the plates 1 and terminals 12 the latter may be countersunk, or the plates may be provided with spacing ribs, and in the case of plates such as those shown in Figs. 7 and 8, side pieces 14, Fig. 5, longitudinal ribs 15 and bottom flanges 13 serve to guide the chain, which passes from right to left in Fig. 1, or at right angles to the drawing in Fig. 5. Above the stencil plates are a number of spring-controlled pivoted fingers 16, connected to the common return. These may be mounted, two rows together. in holders 17, Figs. 1, 10 and 11, to form detachable units which can be slipped between the side pieces 14, pairs 20, 20<1> of spring contacts serving to connect the units to the return lead. The insulating base 10 may be of slate, ebonite, porcelain, marble or the like. or it may comprise an ebonite or like board fitted with contact studs 12 and surmounted by a marble slab having tapped holes in which are countersunk studs connected to the studs in the ebonite board by spring plungers. The contact fingers 16 may be replaced by fine leaf springs or springy wire bristles.

Title: Manufacture of ethyl toluenes and methyl styrenes
IPC: C07C2/68
Filed: 1952-12-03
Abstract: Toluene is ethylated in the presence of a Friedel-Crafts' catalyst and the ethylation mixture fractionally distilled to obtain a fraction rich in toluene, a fraction rich in o-ethyltoluene, and a fraction rich in a mixture of m- and p-ethyltoluenes and containing not more than 0.5 per cent by weight of the o isomer.  This last fraction may be dehydrogenated and a fraction consisting of m- and p-methylstyrenes and less than 0.5 per cent of o-isomer, indane, and indene recovered.  This is polymerizable to colourless, thermoplastic resins.  The ethylation is preferably effected with ethylene and activated aluminium chloride, e.g. at 90-101 DEG  C., in the presence of the recycled o-ethyltoluene fraction and poly-ethyltoluenes whereby formation of the desired products is enhanced.  Unreacted toluene is also recycled.  The products are fractionated under reduced pressure, and a fraction containing o-, m- and p-ethyltoluenes separated and refractionated to recover a mixture of m- and p-isomers usually with less than 0.2 per cent of o-isomer. This mixture is dehydrogenated with or without gaseous diluents and catalysts, preferably in admixture with steam and with solid or fluidized catalysts at 550-700 DEG  C.  The product is fractionally distilled, preferably in a series of columns at reduced pressure, to recover a mixture of m-and p-methylstyrenes.  U.S.A. Specification 2,531,327 is referred to.ALSO:Toluene is ethylated in the presence of a Friedel-Crafts' catalyst and the ethylation mixture fractionally distilled to obtain a fraction rich in toluene, a fraction rich in o-ethyltoluene, and a fraction rich in a mixture of m- and p-ethyltoluenes and containing not more than 0.5 per cent. by weight of the o isomer.

Title: Improvements in engine starting mechanism
IPC: F02N15/06
Filed: 1931-11-06
Abstract: 388,489. Turning - gear. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. Nov. 6, 1931, No. 30852. Convention date, Nov. 15, 1930. [Class 7 (v).] In an electric starter in which the driving pinion 37 is threaded upon a sleeve 17 slidable on splines 13 on the shaft 11 of the starting motor, axial movement of the sleeve is resisted initially by a weaker spring 21 and afterwards by a stronger spring 20. A thimble 24 is arranged between the springs, which bear against flanges 25, 26 on the thimble and against thrust washers 23, 22 engaging respectively the end of the sleeve 17 and a shoulder 12 on the shaft 11. At its outer end, the shaft 11 carries a stop nut 34, a stop member or sleeve 27, an abutment member 32, and an anti-drift spring 31 between the member 32 and a washer 30 on the sleeve 27. On rotation of the shaft 11, the pinion 37 moves axially into mesh with the engine gear 38, a hub portion 39 bearing against the washer 30 and compressing the spring 31. Further rotation causes the sleeve 17 to move to the right, compressing the spring 21 and then the spring 20 until sufficient resistance has been built up to compel the shaft to drive the pinion and the gear 38. If the teeth of the pinion clash with the gear 38, the movement of the pinion to the right on the sleeve 17 compresses the springs 21, 20 until the pinion is turned to bring the teeth into the meshing position. When the engine starts, the sleeve and the pinion are returned to their initial positions by the action of the threaded connection.
