Abstract: 1369719 Prilling DOW CHEMICAL CO 14 April 1972 [16 April 1971] 17461/72 Heading B5A Prills are prepared from a molten or liquid substance, e.g. urea or a urea pyrolyzate, by introducing a stream of the substance through a conduit 30 into a liquid 11 which is maintained at a temperature below that at which the substance solidifies and with which it is immiscible, and shearing the molten or liquid stream, e.g. by the rotary blades 24, to form droplets and initiate crystallization. In the embodiment the input conduit 30 is surrounded by a steam jacket 26 and its outlet is adjustable relative to,the shearing blades by means of the threaded portion 33. The cooling liquid may be an alkane having 8 to 12 carbon atoms, preferably branched, or a mixture of such alkanes. It is maintained at a temperature between 25 and 135‹ C. by a cooling jacket 13 surrounding the vessel 10 or by selection of appropriate rate of flow-through of the cooling liquid. This is introduced through conduit 18 and drawn off as a slurry containing the prills by an outlet 35 the dimensions of which affect the size of prills produced. The speed of the blade may, e.g. be from 1000 to 7000 feet per minute and the stream outlet may terminate ¢ to 8 inches above the blade edge. An alternative form (Fig. 5, not shown) has tapered blades and the material supply conduit set at an angle. The prilled material may alternatively be sulphur, ammonium nitrate, ammonium sulphate, potassium or ammonium phosphates, potassium or calcium chloride, potassium or sodium nitrate, alkali  metal hydroxides or other melts or suspensions or mixtures thereof but is especially applicable to materials which have a tendency to supercool instead of solidifying.

Filed: 1934-06-13
Abstract: 435,579. Automatic couplings for railway vehicles. BAKER, W. S. GRAFF-, 30, Leonard Court, Kensington High Street, London, and ARTHURTON, R. I. D., Homedale, Upper Cippenham Lane, Slough, Buckinghamshire. June 13, 1934, No. 17527. [Class 103 (v)] In an automatic coupling for railway &c. vehicles of the kind in which a coupling-bar 12 projecting from the face of one coupler-head enters the opposite head and is maintained in engagement with a co-operating element 16 by movable locking-means, the locking-device consists of a wedge 29 slidable longitudinally of the vehicle and adapted to force the outer or free end 25 of the bar 12, which is pivoted at its inner end 13, into engagement with a coacting block 16. In the construction shown, each coupler-head is fitted with a coupling-bar and with a block, the latter being disposed at one side of the opening in the face-plate 1, while the wedge 29 is guided by a central longitudinal abutment 20 and is provided with longitudinally arranged vertical surfaces 30, 31 and with an inclined surface 28 that engages a corresponding surface 27 on the opposed coupling-bar. The latter also has an outer inclined surface 22 which engages behind an inclined surface 17 on the block 16 to effect the coupling. In order to ensure a wide area of contact in spite of wear, the surface 17 may be constituted by a rotatable semi-cylindrical block 49 mounted in a recess extending over less than a semi-circle. The wedge 29 is connected by a tubular piston-rod 33 to a piston 37 slidable in a cylinder 38, the piston being pressed outwardly by a spring 32 and being operated by admission of compressed air or other operating-fluid to either end of the cylinder. The wedge is also urged outwardly by a spring 39 located in the tube 33 between the piston 37 and a lost-motion sliding block 34. The face-plates 1 are fitted with joint-rings 53 associated with the train brake &c. pipes and with insulating-blocks carrying electrical contacts 56, the parts being guided into correct position by means of conical studs 45 and conical apertures 46. A modified construction is described in which the blocks 16 are located near the centres of coupler-face-plates and the surfaces 22 are on the inside of the bars 12, while in a further modification a locking-pin engages the underside of the wedge 29 and is operated by a fluid cylinder in series with the cylinder 38. Instead of the duplicate arrangement as shown, one coupler-head may be entirely male and the other entirely female, the male head comprising one or two bars 12 coacting with a single block 16. The operative surface 22 on the bar 12 may be renewable, or it may be constituted by a rotatable semicylindrical member 49 similar to that on the block 16. If desired, the wedge 29 and cylinder 38 may be mounted on the coupling-bar itself, the guide 20 then being dispensed with.

Title: Improvements relating to Wigs
Inventor: KOEHLER ERWIN
IPC: A41G3/00
Filed: 1968-04-17
Abstract: 1,199,671. Making wigs. E. KÍHLER. 17 April, 1968 [29 April, 1967], No. 18147/68. Heading A4V. A wig comprising a support consisting of a transparent flexible synthetic resin foil moulded to the shape of the head, and hairs, the ends of which are unknotted and entirely embedded in the foil, is made by (i) inserting the ends of hairs, or a portion between the ends, through a pierceable outer shell mounted on a male mould of the head, into a pierceable material beneath the shell, temporarily anchoring the hairs to the outer face of the shell and then removing it from the mould and pierceable material so that the ends or loops of the hairs project from the inner surface of the shell; (ii) then mounting a thin piece of textile material on the mould, coating the outer surface of this material and the inner surface of the shell with a synthetic resin and pressing the shell down on to the textile layer; (iii) then allowing the resin to harden to form a foil, releasing the temporary anchoring, and removing the shell so that the hairs are drawn through the shell and remain attached to the textile material to form a wig which is subsequently removed from the mould. The mould is cast from a female impression of the bald area of the head. The hairs are inserted through the pierceable shell, which is preferably made of polyvinyl chloride, by means of a forked needle or a needle having a rounded end with a shallow groove therein. The pierceable material beneath the shell may be a layer of similar substance to the shell, or else the mould itself may be pierceable, in which case it may be cast from silicone rubber. The hairs are temporarily anchored to the shell by a layer of textile coated with adhesive. The textile base of the wig support is preferably a glass fibre material. Before the resin is applied to the inner surface of the shell, the hair ends projecting from this surface may be laid over to give the outward hair lengths a natural slope; alternatively the hairs may be initially inserted at a suitable angle. This method is especially applicable for making patch wigs or toupÚes.

Title: Advertising device
IPC: G09F21/18
Filed: 1926-07-20
Abstract: 274,642. Coll, H. F. July 20, 1926. Opaque liquids, utilizing; actuating. - Advertising devices, of the type comprising figures, signs, &c. adapted to float upon and be submerged beneath the surface of water, are carried on, or formed as, or actuated by, floats, which, when subsubjected to a laterally directed force, rise above or sink below the water surface. The device may consist of an advertising board weighted to float vertically and fitted with inclined vanes beneath the water level so that when pulled along the board will rise or sink. Fig. 3 shows a sign 1 pivoted at 5 by a vane connection 4 to a float 6 and counterweighted by a mass 8. A pull on the float 6 in the direction of the arrow causes the water to press on the vane 4 and submerge the sign 1. Fig. 5 depicts a sign 1 fixed to a cylindrical float 13 fitted with a piston 14 connected to a plate 15. Movement of the cylinder in the direction of the arrow causes the piston to approach the rear open end of the cylinder and expel water therefrom, thus lightening the device. In a similar form the plate 15 is omitted and movement of the cylinder 13 causes the piston to enter further and compress the enclosed air, thus sinking the sign. Another form has a submerged vane wheel partly shielded by a float so as to rotate with lateral movement of the float and raise a sign by a pinion and rack. A further modification has a falling board hinged beneath the surface to a float and provided below the hinge with a counterweight and an extension to which a pull can be imparted.

Abstract: 1,022,222. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. May 1, 1964 [May 7, 1963], No. 18182/64. Heading H4K. A common control circuit including a central programming unit operates with a cycle of 10À24 ms., which is sufficient to deal with consecutive dial impulses, scanning circuits for the detection of dial conditions at junctions having priority over the demands of auxiliary logical circuits in demanding service from the common control circuit, scanning being halted while service is supplied to dialling junctions and any residual time in the common control cycle after all dialling conditions have been processed being devoted to a scan of line circuits for calling conditions, this scan receiving the same priority over auxiliary demands as is afforded the preceding scan. At the onset of a common control cycle a scan of junction groups is started in parallel and a detected dial pulse is registered in a priority circuit, the scan being discontinued until the consequent demand on the common control circuit has been fulfilled. A timing circuit watches the progress of the scan to anticipate what time will be available for other uses of the common control circuit. If after 4À48 ms. the scan is not yet half completed, a ban is put on service to auxiliary logical circuits for a period of 1À92 ms.; if the scan is between half and three-quarters complete however, the ban only extends for 1À28 ms. If the scan is more than three-quarters complete no ban is placed at all. A further check is made at 8À32 ms. and if the scan is less or more than nine-tenths complete a ban of 0À64 ms. or no ban at all is effected. As soon as the scan of junctions is complete a search for calling line circuits is started. It is said that priority for service could involve discriminating between the types of circuit making demand and also between types of demand made.
