Title: Wire printer
IPC: B41J29/18
Filed: 1974-05-07
Abstract: 1435634 Automatic control of printing CITIZEN WATCH CO Ltd 7 May 1974 [17 May 1973 5 July 1973] 20014/74 Heading G3N A wire printer comprising a printer head having a plurality of impacting wires has means effective upon receipt of a character imprint instruction signal for controlling a pulse motor driving the head to move first in one direction and then in the other so that at the completion of movement the head has moved one character imprint, the operation of the wires being effected before the end of movement of the head so that at the end of the movement the head does not overlie the character which has been imprinted. As shown, the operation of a character key causes a control circuit 101 to generate a plurality of driving pulses for a pulse motor 108 coupled to a feed-mechanism 109 and a printer head 110. The driving pulses are fed to an instruction generating circuit 101 generating further pulses which are fed to a forward/reverse rotation circuit 103. The circuit 101 also counts the pulses and at a given value stops circuit 101. The circuit 103 provides outputs 103a, 103b of opposite sense, for predetermined times, which are fed to AND-gates 104, 105, enabled by pulses from the circuit 101. The effect is to cause a retro-movement of the head by a given distance and the subsequent advance of the head by a multiple of this distance to complete a character imprint cycle. The driving pulses from the circuit 101 are also fed to a timing circuit 111 the output of which is fed through a gate 112, enabled by the output 103a, advance movement, to a character pattern generating circuit 113. In addition, a coded signal from a coder 114 is delivered to the circuit 113 whereby, through an amplifier 115 a desired dot character imprint is effected by the head 110 during advance. In an alternative arrangement, as described with reference to Fig. 3 (not shown), the control is responsive to signals from a head feed timing detector and a character imprint timing detector.

Title: Improvements in or relating to fire extinguishers
IPC: A62C13/00
Filed: 1952-08-08
Abstract: 718,660. Ornamenting. FOAMITE, Ltd. (American-La France-Foamite Corporation). Aug. 8, 1952, No. 20021/52. Class 93 [Also in Group XVI] A metal fire extinguisher shell has an area of its exterior surface roughened to form an instruction panel field, and a legend in said field constituted by juxtaposed areas of the roughened metal and. painted areas on said roughened metal. The body shell 2 of a 2¢ gallon type foam fire extinguisher is of brass, stainless steel or other suitable metal and its surface is. polished, painted or plated. An area 6 for an instruction panel is then formed by roughening the surface, as by abrasiveblasting, so as to be dull and contain numerous minute recesses, crevices and cavities. The panel is then cleaned and a coating such as paint, enamel, or lacquer, preferably of baking types, is applied to portions of the panel to form a design 7. 8, 10. The paint or the like may be applied through a silk screen placed in contact with the shell while the latter is rotated, and is of such a consistency as to fill the recesses, crevices and cavities. The areas of the panel unprotected by the paint are then permanently discoloured by oxidation, as by subjection to heat, such as infra-red rays, in air. The painted areas will be thereby baked and hardened. For example, the shell may be heated for five minutes in an infra-red heating tunnel at a maximum temperature of 350‹ F. The highly polished remainder of the shell is relatively unaffected by the oxidizing process. If the paint is later removed, the design will still persist. A colourless protective coating such as a clear lacquer or varnish may then be applied to the entire shell, and the latter again baked.

Abstract: 1496175 Audio visual apparatus RANK ORGANISATION Ltd 6 May 1976 [13 May 1975 21 Aug 1975] 20137/75 and 34760/75 Heading G2E A sound film apparatus can accommodate films of two different gauges, and has an optical sound head for each gauge close to the drive capstan, each head comprising a light source and a light sensitive detector, at least one component of one head being located within an annular groove in the capstan. The arrangement is shown in Fig.1 set up as a projector for 16 mm film, and in Fig.2 for 35 mm film, the film in the latter case being looped additionally round a further roller 1 because of the increased picture-sound spacing. The film passes round a drive capstan 2, which has disposed closely adjacent thereto two optical sound heads and a magnetic sound head. The optical head for 35 mm film consists of a light source 7 and a photo-cell 7', and that for 16 mm film consists of a light source 6 and photo-cell 6'. Normally the film overhangs the capstan so that access can be obtained to both sides of the film. If the same capstan is used for both films, the 16 mm film will not overhang. In this case the photo-cell 6' is located in a holder 10 which fits into a groove in the capstan. The photo-cell 7' for the 35 mm sound head may also be located in a similar groove, although this is not absolutely necessary. The 16 mm set-up can also make use of a magnetic sound head 8.

Title: Improvements in or relating to burners for liquid fuels
IPC: F23D11/24
Filed: 1956-07-02
Abstract: 799,239. Liquid fuel burners. NATTER, O., [trading, as NATTER PRAZIONSMECHANIK, O.]. July 2, 1956 [Oct. 11, 1955; Feb. 6, 1956], No. 20383/56. Class 75(1) In a liquid fuel burner gas (air) and the liquid fuel are mixed in a piston chamber prior to the compression stroke of the piston to feed the mixture to the burner nozzle which is surrounded by a guide cone. As shown the liquid fuel is received into the compression chamber 6 through a conduit 8 having a non-return valve 7 and air is received from a conduit 12 connected to the atmosphere through the crank chamber 1 and a conduit 11 there being non- return valves 13, 10 respectively in the conduits 12, 11, and the fuel-air mixture is forced out under compression by the piston 2 through a non-return valve 14 into the pressure pipe 16 on the end of which is mounted a nozzle 17 having a flange accommodated in a circumferential recess 18 in a cone 19 which can be screwed on to the pipe 16 thereby sandwiching the shoulder of the nozzle against the end of the pipe. The cone is provided with holes 25 over its entire periphery, the supply of air through these holes to the flame being determined by the position and size of the holes. The interior surface of the cone at the wider end is bent over to terminate in a sharp edge 24 so as to cause the formation of eddies in the bend 23 to intensify the mixture formation. The air preferably enters the chamber 6 tangentially, the liquid fuel entry being nearer the lower, or outer position of the piston as described in a second embodiment (Fig. 3, not shown), so that the air is sucked from the commencement of the return piston stroke before the entry of the liquid fuel and a turbulent air movement is obtained to atomize the liquid as it enters the chamber. The air intake is produced by a fan 'arranged on the piston drive shaft driven, by an electric motor and part of the air flows directly to the combustion chamber impinging upon a photo-electric cell to cool the latter which serves for supermission of the combustion operation. The air feed to the compression chamber passes through the crank chamber and takes up oil from the oil sump ensuring lubrication of the piston and cylinder. The fan may be that used to cool the electric motor.
