Title: Forced air draught gas burning appliances
IPC: F23Q9/08
Filed: 1972-04-17
Abstract: 1421376 Igniters; forced draught gas burners DUNLOP Ltd 6 April 1973 [17 April 1972] 17550/72 Headings F4F and F4T A forced air draught gas burner comprises a main burner 2 having a fuel gas supply pipe 15 and a forced air draught supplied, e.g. by an electric fan, through duct 1, an ignition arrangement comprising ignition means (7), Fig. 2 (not shown), projecting into the combustion zone of a pilot burner 10, 14 for ignition thereof, the pilot burner communicating with duct 1 and being arranged so that pilot fuel gas supplied by pipe 5 is only carried into the pilot burner combustion zone if the forced air draught is present, and a pilot burner flame detector (8) arranged to control fuel gas supply to the main burner. On start-up of the burner a fan is energized and the first stage of a two-stage fuel gas valve is activated to supply gas to the pilot burner; this gas being carried into the pilot burner combustion zone by part of the air draught entering burner tube 10 via holes 11, 12. If the draught is absent the pilot fuel gas entering tube 10 via low permeability foamed metal plug 6 passes out of hole 12 and no pilot flame results. Normally, however, the fuel gas reaches the pilot combustion zone and is ignited by an ignition probe (7) connected to a high tension source, the pilot flame being detected by ionization probe (8) which thus actuates the second stage of the fuel valve to supply fuel gas to main burner 2 for ignition by the pilot burner. If the pilot flame goes out, e.g. due to air draught failure, the probe (8) causes the fuel valve to stop supplying main burner 2. The pilot burner has a tube 10 of rectangular section.

IPC: A23G9/08
Filed: 1949-07-04
Abstract: 666,297. Ice-making. SIDDALLS ICE CREAM CO., Ltd., and MALLARD, J. T. L. July 4, 1950 [July 4, 1949], No. 17571/49. Class 29 Frozen shaped products such as water ices are made from aqueous solutions in a split metal mould by pre-cooling the mould so as to freeze the liquid in the joints between the sections 1 of the mould to form a seal therein before filling the mould cavity 4 with the syrup &c. to form the frozen shape. The mould sections are located relatively to each other by dowels 2 and have vertical ribs 5 at the back of each half-impression 4 to give added heatabsorbing mass. The mould is first wetted and passed through a cold tunnel to lower its temperature well below freezing point and form at least a partial seal between the two sections. The material to be frozen is then filled into the mould, penetrating into the joint and forming a frozen layer. The mould is then suspended in chilled brine to complete the freezing. In a modification a cooling fluid is passed through the mould for pre-cooling, sealing, and freezing. Clips on the mould hold suitable sticks, and inclined lugs 6 are provided for separating the mould parts after freezing by means of a wedge.

Title: Improvements in photographic reproduction processes
Inventor: MARRIAGE ANTHONY
IPC: G03C7/28
Filed: 1952-07-11
Abstract: 724,150. Photographic dye-transfer process. KODAK, Ltd. Oct. 8, 1953 [July 11, 1952; July 11, 1952], Nos. 17592/52 and 17593/52. Class 98 (2). The positive dye image formed by treating a photographic silver image with a silver-dyebleach bath in the presence of a dye which is bleached in the locality of the silver image, is transferred to a receiving support. The dyebleach bath may comprise acid thiourea and may also contain an accelerator such as anthraquinone-2-sulphonic acid or 2 : 3-dimethyl quinoxaline. The dye, which is preferably a diffusible acid azo dye such as Chlorazol Fast Pink BK, Naphthalene Black (I.C.I. No. 30745), Direct Sky Blue GS 300, Acid Brown or Chlorazol Black, may be in the emulsion or developer, or it may be applied after development from a separate bath or from the bleach bath. The receiving support may be plain paper, or paper coated with gelatin. It is preferred to treat the receiving support with dilute aqueous alkali such as sodium carbonate or ammonia solution before transfer, which solution may also contain sodium hexametaphosphate, and particularly good results are obtained if it is treated with strong alkalis such as 4 per cent ammonia or N/10 caustic soda or with an aqueous thiosulphate solution with or without the dilute alkali treatment. The emulsion layer containing the dye may also be wetted with alkali metal carbonate solution before transfer. Part only of the dye may be transferred and a number of copies can thus be obtained from the original. When all the dye is exhausted, the original emulsion may be redyed and re-bleached and further copies obtained, and this may be repeated until the silver of the original negative image will no longer bleach the dye effectively.

Title: Improvements in the method of and apparatus for making cementitious articles
IPC: B28B7/14
Filed: 1919-07-17
Abstract: 152,748. Crozier, A. O. July 17, 1919. Processes; moulding - machines; stream - cutting machines; feeding.-Cement and like articles, such as bricks, blocks, and pipes, are made by pouring into an upright shaft a column of cement mixture of such a height as to effect by its own weight a compacting of the lower part ot the column, which is them cut off, or cut off and cut up, and removed; the remainder of the column then descends, and the shaft is filled up again. Fig. 9 shows a machine for carrying out this process. The mixture fills a hollow shaft 18, the lower end of which is closed by one of a series of removable plates 20, shown in its lowest position after the lower end of the column of material has been cut off by an horizontal knife 19 and cut up by a number of vertical knives 17, all reciprocated by a pair of connecting-rods 24. The plates 20 are stacked in a container 30, and are removed from its lower end by pawls 37 on a sliding frame 31 reciprocated by a lever 32. A plate 20 arriving beneath the column 18 is at once raised by a toggle 42 and table 40, and the knives 17, 19 are quickly withdrawn, so that the cement mixture, hitherto supported in the shaft 18 by the knife 19, falls suddenly upon the plate 20, so that the lower end of the column is compacted and freed from excess moisture. The knife 19 then moves forward through horizontal slots in the lower end of the shaft 18, and the knives 17 then pass through a number of similar vertical slots, and cut up the block into smaller pieces. The plate 20 is then lowered suddenly; the bricks stick momentarily to the underside of the knife 19, which gives to them a characteristic roughened surface. The knives are mounted on guide sleeves 21 moving on guide rails 22, and are reciprocated by gearing in connexion with the main shaft 50, which also drives, by means of wormgearing, the shaft 45 and cam 33 for moving the levers 32, 42. Hollow bricks may be made by placing in the shaft 60, Fig. 16, a number of vertical rods or cores 61; the lower end of the column is cut off by a pair of horizontal knives 63 with serrated edges. Lengths of pipe may be made in a similar machine which may have a rotating core 61 and shaft 60 in order to render the surfaces of the pipe smooth. The knives may have bevelled edges in order to increase, if desired, the compacting of the material, and may be replaced bv taut wires, saws, or the like, followed by a plate serving to support the mixture in the shaft 18.

Title: Intermittent drive mechanism
IPC: H01H43/10
Filed: 1971-05-28
Abstract: 1315742 Escapements MALLORY TIMERS Ltd 28 May 1971 [29 June 1970] 18058/71 Heading F2X [Also in Division H1] An intermittent drive mechanism comprises a constant-speed drive 22, a first cam 38 rotatably driven thereby, a second cam 43 coaxial with cam 38 and relatively rotatable, energy storage means 46 coupling the cams together and storing energy on advance of the first cam relative to the second cam; stop means 48, 50, normally preventing rotation of the second cam and intermittently in response to rotation of the first cam permitting limited rotation of the second cam whereby energy stored in means 46 advances the second cam with a snap action; and mechanical damping means 28 to retard the snap-action advance of an output member driven by the second cam. As shown, a drive for a programmer, for example, comprises a synchronous motor 20 driving a constant speed member 22 via reduction gearing 20<SP>1</SP>, 20<SP>11</SP>, 36. Member 22 comprises a gear 34 integral with a gear 32 and snail cam 38 and is coupled to a gear 43 by pre-stressed torsion coil spring 46. Gear 32 may be used for subinterval-switching, for example. Gear 43 has an integral cam-like projection 40 which normally prevents rotation of gear 43 by abutting one of two spring urged stop pawls 48 or 40. Motor 20 thus stresses spring 46 until the cam 38 lifts the pawl restraining projection 40, whereupon gear 43 is rapidly driven until, after 180 degrees rotation, projection 40 abuts the other stop pawl. Gear 43 meshes with a gear 52 coupled to an output pinion 54 via a unidirectional clutch (84, 86, Fig. 3, not shown) such that output pinion 54 performs intermittent 180 degree steps. To avoid excessive wear due to too vicious stepping a damping escapement 28 retards the motion of gear 52. This comprises a ratchet wheel 59 staked to gear 52 and cooperating with teeth 70, 72 on a slidable member 58 such that wheel 59 can only rotate by reciprocating the slider 58. A second motor 18 provides rapid advance of the output pinion 54, when desired, by means of gears 18<SP>1</SP>, 17 and 76, overrunning the unidirectional clutch to gear 52. Output pinion 54 may also be driven at a slower rate than the normal programme cycle (for a long soak in a washing machine, for example) by providing a greater gear reduction from motor 18, and de-energizing motor 20.
