Abstract: 1380589 Letter sorter D M GUNN 22 Nov 1971 [23 Nov 1970] 54066/71 Heading G4M A letter sorting machine senses positioning marks on a stamp and positions a data reader to a position corresponding to data on the stamp. A postage stamp 10 (the subject of Specification 1,380,590) carries positioning marks 20, 21 and a code grid 11 representing, e.g. the American postal zip code. The positioning marks are not readable by the code grid reader and may each have different reading properties. They may both be magnetic, fluorescent or conductive or may be one magnetic and one fluorescent. Letters carrying the stamp are fed, with the stamp near the lower surface, one by one by a roller 46 to endless belts 45, 48 and are carried past a reader 60 sensing the positioning marks. In the event of missing or conflicting stamps a reject signal is produced operating a vacuum or a pusher arm 66 to eject the letters to a bin 68. If a correct stamp is detected read heads 71, 72 responsive each to a positioning mark identify the orientation of the marks and feed signals to a position control mechanism 80. The letters advance to a zip code reader 77 containing photo-cells which is mounted for rotary and up and down movement controlled by signals from mechanism 80, to align the reader with the stamp orientation. Signals read from the zip code control the sorter 95. The code grid may be marked by pencil or may be punched and the code when read may be printed on to the letter.

Abstract: 1,174,597. Luminescent materials. WESTERN ELECTRIC CO. Inc. 20 Dec., 1966 [20 Dec., 1965], No. 56881/66. Heading C4S. [Also in Division H1] An electro-luminescent semi-conductor device comprises a single AIII-BV semi-conductor body containing a group IV element as substantially the sole significant impurity, a portion of the body being compensated by the Group IV element acting as both donor and acceptor. Fig. 2 shows a gallium arsenide crystal 31 with PN junction 35 from which light 42 is emitted on application of forward bias. The crystal is prepared by heating a silicon doped GaAs crystal in hydrogen to out diffuse arsenic from the upper portion and zinc is then diffused in to form P + region 36 to provide a low-resistance contact. The out diffusion of the arsenic provides a compensated portion 34 in which the silicon atoms act as both donor and acceptor. The compensated portion may alternatively be provided by freezing out from a gallium rich silicon doped GaAs melt and then heat treating in an over-pressure of arsenic. In another embodiment (Fig. 1, hot shown), light is directed against a weak N or compensated region (14), resulting in photo-luminescence and emission of light (19); the crystal again consists of silicon doped (5 x 10<SP>18</SP> atoms/c.c.) gallium arsenide, the compensating region being produced as before, by outdiffusioning arsenic from the region unprotected by silicon oxide layers (13). Gallium phosphide may be used in place of gallium arsenide and germanium or tin in place of silicon. The construction may be adapted to provide coherent light, and cathodoluminescence may also be utilized.

[Class 126] In a combination cooking, water-heating and room-warming stove having dampers 2, 10, 12 controlling the main flue 3, oven flue 11 and boiler flue 13, a vertically sliding fire-door 1, serving to form a closed fire in the down position and an open fire as it is raised, controls the movements of the main flue damper 2 so that closing of the door effects substantial closure of the damper if this is open. As shown, the door 1 carries a lug 7 adapted to engage the upturned end 6 of a pivoted lever 5 the other upturned end 8 of which is weighted and contacts with the underside of the damper 2. Complete closure of the damper is prevented by an adjustable stop 2a or by the provision of an aperture in the damper itself. The oven and boiler dampers 10, 12 are operated by sliding rods 14, 15 recessed at 20 to receive a cam 19 mounted on a shaft 17 carrying an operating handle 18. The cam shaft 17 is axially movable so that it can be pulled out or pushed in to engage the cam with either of the recesses 20 in the bars 14, 15; in a modification two cams 19 are provided so that the oven and boiler dampers 10, 12 are operated simultaneously. Each of the rods 14, 15 is fitted with a wedge-shaped abutment 16, which, when a rod is moved to open its respective damper, contacts with the underside of the main damper 2 to move it to the closed position if it has not already been closed by movement of the fire-door 1.

A photographic process comprises imagewise exposing a support with a layer thereon containing a diazonium salt so that a latent image is produced and either the exposed or unexposed areas become capable of retaining a powder developer or do so on subsequent treatment and then developing the retentive areas by applying a powder developer. In the examples powdered diazonium salt is rubbed into a paper support and the material is imagewise exposed. The exposed areas are developed either with a coloured toner or a powdered coupler and the negative powdered image obtained is heated to fix it (when using a toner) or to develop a coloured image (when using a coupler). Alternatively, if powdered diphenylamine which may be admixed with carbon tetrabromide is used, a visible image is produced by exposure to ultraviolet radiation. If 2, 5-diethoxy 4-benzoylamido benzene diazonium chloride alone or 4-diethylamine-benzene diazonium borofloride or 2:5 diethoxy-4-morpholine benzene diazonium borofluoride admixed with trichloracetic acid is used, a positive coloured image is produced on development. Positive images are also produced by lengthening the exposure time or by dusting the exposed areas with polyethylene powder, heating and dusting the remaining areas with coloured toner. Printing plates are produced if a hydrophobic toner is used for development. Multi-colour line images are produced by imagewise exposure to a line negative and development with appropriate coloured toner and repeating the exposure and development. The preferred toner is a petroleum hydrocarbon resin and a dye. Reference has been directed by the Comptroller to Specification 1,105,112.

In Fig. 2 the web is pressed against the roll 10 first by belt 11, then by belts 11 and 12 together and then by belts 11, 12 and 13 combined as it moves round the roll giving a stepwise increase in pressure. The magnitude of each pressure and the duration of its application are varied by moving the rollers 20, 22, 24 and 21, 23, 25. To prevent roll 10 from being distorted by the pressures its surface may be supported from inside by a body of liquid or by a shoe pressed against its inside surface by a piston. In Figs. 4 and 5 the web W and felt F are pressed between impervious belts 110, 111. The pressure, applied by bearing members 119, 120 gradually increases between converging surfaces 123, 124, is uniform between chambers 121, 122 where it is applied by pressurized fluid inside the chambers, and decreases rapidly between diverging surfaces 125, 126. The pressure applied between surfaces 123, 124 and 125, 126 is varied by altering the distance between opposing surfaces. In Fig. 9 the pressure is increased stepwise between pairs of opposing pressure chambers, 22-225. Fluid is supplied to a typical chamber 220 via a corresponding control valve 230 and a chamber 226 which has flexible side walls 227, 228 to prevent the applied pressure being affected by bending of the supporting beam 218. The chambers may be arranged around a cylinder. The lower belt 211 may be omitted. Pressure may be applied to only one side of the web.
