Abstract: 1,141,562. Incinerators. GENERALE THERMIQUE. 4 May, 1967 [9 May, 1966], No. 20792/67. Heading F4B. A refuse incinerator having a burner unit 19 comprises a cylindrical grid assembly 8 rotatably mounted via rollers 12 within a casing formed by two coaxial cylinders 1 and 2 spaced apart to define an annular space 3 therebetween. One of the rollers is connected to a drive motor (not shown). The grid 8 comprises an annulus of tubes 9 wherein each tube has several radial branches 14 connected together by plates (15, Fig. 2) to define a continuous longitudinally extending helicoidal path. Refuse from a hopper 18 enters through a frusto conical section 16 having vanes 17 to direct the refuse into the incinerator, unburnt refuse being rejected through a section 21 into a hopper 20, and the ash passes through the grid 8 into a box 4. An extraction fan (not shown), connected to the box 4, induces air for combustion through an adjustable air flap 24 into the space 3 where it is distributed through apertures (25, 34, Fig. 3) to the box 4 and to the grid 8 respectively. Additional air is induced through apertures 22, 23 into the tubes 9 and out through the branches 14 into the refuse bed. In an alternative embodiment shown in Fig. 5, the grid tubes 9 are joined together via perforated refractory metal elements 41. Radial blades 42 of similar material are attached to the tubes. Combustion products exit into a chimney 52 mounting an extraction fan via a chamber 50 which contains catalyst elements 51. A push-rod assembly (56, Fig. 4) forces refuse from a hopper (57) into the grid 8.

Abstract: 1455066 Air filter system PARRS-CRAMER (GREAT BRITAIN) Ltd 10 May 1974 [4 June 1973 24 Oct 1973] 20897/74 Heading BIT [Also in Divisions D1 and D2] Fibre waste generated in spinning units 11 of open-end spinning machines 10 is entrained in spinning air removed by a duct 12 associated with each machine, the duct 12 leading to a primary filter 20 serving a group of machines, fibre waste trapped by the primary filter being periodically dislodged and directed with the spinning air to a secondary filter 25 which serves all of the primary filters. Thus any fire ocouring in waste from a machine is confined to the primary filter and only effects a single group of machines. The primary filters 20 each comprise a screen 22 rotatable through 180‹ to dislodge waste. This rotation may occur at timed intervals or in response to a pressure sensor 35. The secondary filter comprises a screen 25a traversed by a vacuum cleaner 25b which transfers waste to sacks 25r. If fire occurs in the primary filter a sensor 50 after a time delay, which allows the fire to possibly burn out, activates extinguisher nozzles 60 and closes a flap 66 to confine the fire. Also the associated spinning machines are stopped. If fire occurs in the secondary filter a sensor 50'activates extinguisher nozzles 60', closes isolating flap 66' and stops all of the spinning machines. Air after removal of the waste is recirculated to the spinning room through outlets 44 in a duct 43. A suitable control circuit is illustrated in Fig. 7 (not shown). Specifications 1307762 and 1249159 are referred to.

To play the game the sliding discs are set up on the board 10 in the area bounded by a triangle 13, with those discs that are not red upon correspondingly coloured positions on the board. A player places his striker disc on the baulk line 12 and flicks it towards the sliding discs arranged in the triangle to attempt to impact against them and drive them into the targets or pockets 2, 3, 5, 6. The targets or pockets are coloured with the same colour as some of the discs e.g. pocket 6-blue, pocket 2-yellow, pocket 3-black and pocket 5-tangerine. Scoring and playing procedure is similar to snooker.

Abstract: 320,900. Stephens, A. J., (Leeming, H. T.). July 23, 1928. Copying-telegraphs; television.-Picture signals are recorded, preferably together with sounds, on a gramophone record at the receiving station and are subsequently used for the reproduction of pictures. In the case of a copying telegraph the transparency to be transmitted is mounted on a revolving drum (Fig. 1, not shown) which is geared to a light-interrupting disc and encloses the photo-electric cell. The resulting picturesignals are transmitted by modulated carrier waves and are recorded on a gramophone record. Sounds may simultaneously be transmitted and recorded in the same groove on the record, which may be a metallic disc or ribbon. The sound record may be laterally cut while the picturecurrent record is vertically cut. The record 24 may then be mounted for reproduction, Fig. 2, on a turn-table which is geared to a scanning disc 47, so that the picture-signals, derived from a pick-up 41, are reproduced on a screen or film 48, while the recorded sounds, derived from the pickup 49, are reproduced in a loud-speaker 53.
