Title: Method of making a decorative tile and apparatus therefor
IPC: B28B3/02
Filed: 1960-08-22
Abstract: 944,706. Embossing; ornamenting. WOOD CONVERSION CO. Aug. 22, 1960 [Sept. 28, 1959], No. 29022/60. Headings B6C, B6G, B6H and B6J. [Also in Divisions E1 and F4] A method of forming one or more fissures in a decorative tile containing a substantial quantity of fragile synthetic mineral fibres comprises the steps of mechanically pushing the body of the tile inwards from one face thereof over one or more areas to a depth which is less than the thickness of the tile body thereby to break the synthetic fibres over the area or areas to the depth to which the tile body is penetrated; and removing the resulting debris from the tile face in which the fissure or fissures is formed. A die 10 for forming the fissures comprises relief portions 13, 15 and a number of pins 19, the latter forming soundabsorbing holes in the tile. A tile 25 to be embossed is placed below a stripper plate 17 on a base 26 and the die 10 is then pressed down into contact with the tile, the chief portions of the die and the pins 19 passing through correspondingly shaped apertures 13<SP>1</SP>, 15<SP>1</SP>, 191 in the stripper plate 17, until side portions of the die abut against adjustable stops 29 mounted in the base 26. The plate 17 is mounted on spacer blocks 29<SP>1</SP> which are replaceable by blocks of a different size so as to accommodate different sized tiles. The relief portions 13, 15 of the die have substantially vertical side walls 18. The degree of penetration of the die into the tile can be regulated by adjustment of the stops 29. After being embossed by the die 10 the tile 25 is placed on a conveyer 30 and passes under an embossing roller 31 having projections 32 which make small indentations in the surface of the tile. The projections 32 may be nails driven into the roller and having had their heads cut off or grit or rock particles glued to the roller. Thereafter the tile passes beneath a suction hood 33 (see Division F4) where the debris caused by the embossing operations is removed and then beneath a spray station 40 and a coating roller 43 where coating composition is respectively sprayed into the fissures and applied to the flat surface of the tile. Specifications 913,268 and 944,707 are referred to.

Title: Improvements in or relating to facsimile transmitters
IPC: G07F17/26
Filed: 1939-10-31
Abstract: 536,098. Facsimile telegraphy. STANDARD TELEPHONES & CABLES, Ltd., (Deakin, G.). Oct. 31, 1939, No. 29052. [Class 40 (iii)] [Also in Group XVIII] In an automatic facsimile transmitter of known type a message receiving slot is provided the width of which can be selectively adjusted to receive message blanks of different widths. The selection may be effected by manually operated keys electrically controlling from a remote point, or by coin operation. Fig. 1 shows a cabinet 10 fitted with a blank-receiving shoot 11 divided into two portions by a partition 19. Each portion is closed at the top by a pivoted cover 14, 15 opened by coins inserted into coin shoots 18a, 18b, 18c, 18d. It is assumed that coins inserted in the first three shoots will cause cover 14 to open, and a coin placed in shoot 18d will open both covers 14 and 15 and remove partition 19, thus allowing insertion of a blank of full width. Fig. 2 shows the mechanism as applied to shoot 18c, the inserted coin 25c resting on a pivoted finger 20 held up by a spring 22. The cover 14 has a rear extension 24 furnished with a catch underneath and held by a spring-retracted pawl 28 to keep the cover closed. A foot 29 closes a switch e<SP>1</SP> in the circuit of an electromagnet X<SP>1</SP> which, when energised, attracts the finger 20 and causes the pawl 28 to be thrown back and the extension 24 to be lifted till a projection 25 thereon is caught by a pawl 26 which thus holds the cover open. The switch e<SP>1</SP> is at the same time opened. The inserted coin first prepares the circuit by pressing on a switch c<SP>1</SP> and current passes when handle 17 is turned to make contact at 17a through to earth. When the coin 25c passes to the magazine, or is refunded by operating a lever RF, the circuit is broken and the finger 20 rises again. The pawl 26 has a bellcrank armature attracted by a re-set magnet Y1 which also closes the coin shoot when a coin has been inserted by raising a lever 27. The shoot 11 has a spring- and magnet-controlled bottom stop on which the inserted blank rests and a horizontally moving knife, spring- and magnetcontrolled, passes through slots across the top of the shoot 11 to cut off any excess area of the blank.

Title: Process and apparatus for generating cold
IPC: F25B9/00
Filed: 1947-10-31
Abstract: 635,948. Refrigerating. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Oct. 31, 1947, No. 29143. Convention date, Nov. 14, 1946. [Class 29] For generating cold a volume of gas undergoes the following processes in a closed cycle. Phase I: The volume of gas is contained under a pressure P in a hot cylinder 2. Phase II: The gas is transferred to a cold cylinder 1 at constant pressure being cooled in a conduit 3 containing regenerative material. Phase III: The gas is expanded to a lower pressure p by moving up the piston 14 whereby part of the gas produces cold in the cylinder 1 and the rest flows to the cylinder 2 being heated in the conduit 3. Phase IV: The part of the gas left in the cylinder 1 is transferred at constant pressure p to the cylinder 2 being heated in the conduit 3 The gas is then compressed to the initial pressure P in the cylinder 2 by the piston 14, thus completing the cycle, the heat of compression being removed. In a practical embodiment (Fig. 2, not shown) the cylinder 1 is replaced by several cylinders connected in parallel and operating at different temperatures. Fig. 3 shows a modification of the diagrammatic apparatus shown in Fig. 1, the cylinder 1 being replaced by a horizontal cylinder 6 containing a displacer 5 having regenerator surfaces 3'. Fig. 4 shows a stepped cylinder 6 and displacer 5. Other embodiments showing displacers having regenerator surfaces operating at a series of different temperatures are described. Instead of the compression being intermittent, a continuously acting compressor may feed into pressure reservoirs which are connected to the regenerator at the proper times by valves. By operating two similar machines in antiphase, the regenerator may be dispensed with. The apparatus may be used for liquefying gases.

Title: Improvements in and relating to the manufacture of electrical condensers and materials therefor
IPC: H01G4/20
Filed: 1927-11-03
Abstract: 305,515. Jodrey, E. W. Nov. 3, 1927. Condensers are made according to a process which consists in coating or impregnating metal foil paper with cellulose esters, such as acetate or colledion. Tissue paper has a continuous coating of a suitable adhesiveness applied to one or both its sides by means of a roller, and metal powder is applied to the surface which, after drying and calendering, is burnished or treated so that the powder forms a continuous layer. The dielectric is applied by running through a solution, or painting with solution, or the coating may be formed of very thin sheets of a cellulose ester. The ester is caused to adhere tc the tin, aluminium, copper, or other metal by means of an adhesive such as ester solution, ester solvent, varnish, or cement, the foil surface being roughened by mechanical or chemical means, such as a sand blast or an acid. The condenser so formed may be sealed by the use of a cellulose ester, applied either as a film round the layers or to hold them in position. The Provisional Specifications also state that the coating or impregnating is applicable to metallic sheets.

Abstract: 334,411. Aktiebolaget Forenade Piano-Och Orgelfabriker. Aug. 28, 1929, [Convention date]. Starting and stopping.-In a gramophone which plays when a coin is inserted, means are provided for preventing repeated playing of a record. On the insertion of a coin in the shoot 8, the arm 9 of the pivoted lever 7 moves downwards, thereby actuating a bell-crank lever 5 so as to remove the brake 4 from the brake disc 3 and release the playing mechanism. The tone-arm now moves inwardly towards the centre of the record causing the inclined 'teeth 18 of a rod 14, connected to the tone-arm, to pass freely over a strap 13 attached to a pendulum 11 suspended from the gramophone casing. If the tone-arm is now moved back to the starting position, the teeth 18 engage the strap 13, causing the pendulum to swing. The lever 7, previously supported by the catch 12 on the pendulum, loses its support and swings down, releasing the coin 10 and thereby locking the playing mechanism. To limit the swinging of the pendulum, an arm 19 is attached thereto in such a manner as to lift the rod 14 from below when the pendulum is deflected, so that the teeth 18 release their hold of the strap 13 and the pendulum tends to assume a vertical position.
