Title: Improvements relating to golf balls
IPC: A63B37/00
Filed: 1964-01-21
Abstract: A filled elastomer is cured in the presence of a monomer capable of acting as a cross-linking agent for the elastomer, the curing being effected by the application of heat and pressure and in the presence of a catalyst of the free radical type for promoting polymerization of of the monomer.  The elastomer is preferably a synthetic rubber such as a polymer, copolymer or terpolymer of butadiene, isoprene or chloroprene initially in a solid or viscous liquid state. Suitable monomers comprise ethylenic unsaturated acid and polybasic acid esters of unsaturated alcohols, including furfuryl alcohol, polyamine amides and imides and polyol esters and anhydrides of ethylenic unsaturated acids, vinyl compounds including vinyl silanes, and low molecular weight reactive polymers such as polymers of butadiene, isoprene, chloroprene and epoxidized derivatives of these materials. The filler material is preferably silica or silicate, together with a minor amount of cork.ALSO:A homogeneous golf ball is moulded from a filled elastomer which is cured in the presence of a monomer capable of acting as a cross-linking agent for the elastomer, the curing being effected by the application of heat and pressure during the moulding process, and under conditions which additionally result in the polymerization of the monomer.  The resultant material comprises an elastomer highly cross-linked in a three-dimensional network with long flexible cross links.  The elastomer is preferably a rubber such as a polymer, co-polymer or terpolymer of butadiene, isoprene or chloroprene, and the monomer is preferably a diacrylate or dimethacrylate, though other possible ingredients are referred to in the Specification.  The mix also comprises a catalyst for promoting polymerization of the monomer and a filler to adjust the density of the ball.  The filler may wholly or partly comprise white pigment for colouring the ball.

IPC: G21C15/04
Filed: 1956-01-26
Abstract: 847,216. Nuclear fuel elements. PARSONS & CO. Ltd., C. A. Jan. 28, 1957 [Jan. 26, 1956; March 15, 1956], Nos. 2666/56 and 8209/56. Drawings to Specification. Class 39(4). In a nuclear reactor fuel element, suitable for arrangement in a vertical channel in the moderator together with a number of other such elements, the mechanical load is supported on an outer graphite container and not on the fuel itself. The fuel is contained in a magnesium alloy tube, surrounded by and spaced from the graphite cylinder which is inserted in the vertical channel. The alloy tube has helical fins and longitudinal baffles which engage with slots in the graphite cylinder and which may be of magnesium, beryllium or zirconium. When the element is lifted from the channel, as the baffles and the graphite cylinder engage at the slots, the cylinder moves with fuel tube. Cooling gas passes between the tube and cylinder and between the cylinder and channel walls. Specification 847,214 is referred to.

Title: Improvements in electro-magnetic vibratory apparatus particularly telephones
IPC: H04R11/00
Filed: 1924-02-01
Abstract: 211,123. Signal Ges. Feb. 12, 1923. [Convention date]. Void [Published under Sect. 91 of the Act]. Drawings to Specification. Diaphragm vibrators.-In the construction of electromagnetic vibratory apparatus, particularly telephone instruments, in order to obtain an optimum value for the product B d B / d H - it has been usual to mount on a thin iron diaphragm, which is saturated with a value of the induction B higher than that giving the optimum value of this product, sufficient armature iron to reduce the induction to the optimum value. In order to avoid too great an increase in the mass of this armature, it is, according to the invention, formed of iron having the highest possible saturation value, such as Swedish charcoal iron or electrolytic iron, which saturates at about 18000. It is thus possible to work with higher induction in the air gap. This method may be combined with the formerly proposed method of inclining the limbs of the magnet, in the case of a horseshoe magnet, towards one another. The magnet may also take the form derived from a horseshoe magnet by rotation about its central axis.

Abstract: 724,924. Steam-raising in boilers; superheaters and reheaters. BABCOCK & WILCOX, Ltd. Jan. 30, 1953 [Jan. 30, 1952], No. 2716/53. Classes 123 (2) and 123 (3). In a steam boiler having a two-part superheater 4, 5 and also a two-part reheater 7, 6, these parts are protected during starting-up of the boiler by passing a sufficient quantity of steam, at a pressure of about 40-50 per cent. of the normal boiler pressure, through the superheater and then through pressure reducing means 20 and an attemperator 21 to the reheater. The superheater comprises an inlet header 9, intermediate headers 12, 15 with associated attemperator, (not shown), and an outlet header 16 with steam pipe 17 leading to the high pressure stage of a turbine, while the reheater comprises inlet and outlet headers 22, 23 connected, respectively, through the attemperator 21 to a steam inlet pipe 19 from the high pressure stage of the turbine and to pipes 24, 26 leading to a low or intermediate stage of said turbine. The outlet pipe 24 from the reheater has an extension which terminates in an outlet 34, is fitted with a valve 35, and is connected to the part 17a of the superheater outlet pipe 17 by a by-pass 33 with valve 32 ; a pipe 27 with valve 28 and the pressurereducing valve 29 also connects the pipe 17a with the pipe 19 between a stop valve 20 in the latter and the attemperator 21. At starting-up the valves 20, 28, 35, also the valves 18, 25 in the superheated steam pipes 17, 26, are closed and the valve 32 is opened ; the starting-up burners associated with the pulverised fuel burners in the furnace chamber are then put into operation whereupon, once steam collects in the boiler drum 11, steam will flow through the superheater parts 4, 5, and any water in the superheater will be blown into the pipe 17a and discharged through the by-pass 33 and outlet pipe 34. The valve 32 is next closed and the valves 28, 35 are opened, when steam from the superheater 4, 5 will flow through the pipe 27, reducing valve 29, attemperator 21 and the reheater parts 7, 6 to the outlet pipe 34. As soon as an adequate steam flow has been secured the main burners are brought into operation and the valve 18 is opened ; later the valve 20 is opened and the valve 28 closed, and, finally, the valve 25 is opened and the valve 35 closed simultaneouslv. In modifications steam from a separate source is supplied to the lower headers of the steam boiler or, alternatively, direct to the superheater part 4.

Abstract: 1,031,511. Photocopying. IMAGIC PROCESS Ltd. Jan. 15, 1963 [Jan. 25,1962], No. 2870/62. Heading G2C. In a device for developing an ink-retaining latent image by applying powdered ink to the surface of an image-bearing sheet, the device comprising guides for the sheet and a driven transfer member carrying powdered ink so that their paths run closely adjacent in an inking region, a doctor fitted in the inking region acts directly on the inkcarrying surface of the transfer member to loosen the ink and facilitate its delivery to and retention by the latent image. As shown in Fig. 1, a roller 1 within a powder reservoir 3 produces a heap of powder ink due to the doctor blade action of the reservoir wall and the sheet 7 bearing the latent image passes over this heap to develop the image. Alternatively the heap of powder may be formed by a stationary doctor engaging an endless belt which also passes about a rotatable apertured cylindrical powder supply container. Fig. 2, not shown. In a further embodiment (Fig. 3, not shown), a tape wound between rollers is employed, the tape being loaded with powder from a hopper. To ensure more thorough development of the image, the powder carrying member may be oscillated as well as intermittently fed forward. Such an arrangement is shown in Fig. 4 employing doctor wires 39 where the powder carrying member is a preloaded tape 34 but it may also be an endless belt loaded by passage around a perforated drum containing the powder (Fig. 5, not shown).

Abstract: 571,146. Driving magnetos. HASLER AKT.-GES. WERKE FUR TELEPHONIE UND PRAZISIONSMECHANIK. March 4, 1943, No. 3567. Convention date, Feb. 2, 1942. [Class 35] An impulse coupling for a magneto comprises an annular trough member 2 secured to the rotor shaft 1 of the magneto by nut 6 and washers 4, 5, and a driving member 3 freely mounted on the hub 2<1> of member 2, the two members being interconnected by a spiral spring 9. Member 3 carries a gear-wheel 12 driven by the engine. The periphery of member 3 has lugs 8 which are located, with considerable angular freedom, in the recesses between upstanding lugs 7 provided on the rim of member 2. The action of the spring, when turning over the engine is to allow the rotor shaft to remain stationary (due to the magnetic forces acting on the rotor) until the lugs 7, 8 engage, the spring tension increasing during this period. The two members then rotate as a unit until the rotor has turned through a half-pole pitch, when the magnetic forces reverse and snap the rotor through the remainder of the pole pitch, which action is accelerated by the spring unwinding. The initial spring tension may be adjusted by relative rotation of the members 2, 3. Specification 552,792 is referred to.
