Filed: 1937-11-04
Abstract: 505,110. Arrangements of vertical boilers. CROMPTON, C. E. Nov. 4, 1937, No. 30284. [Class 123 (ii)] Steam or hot water boiler plant comprises two or more boiler shells A each with a burner B and containing a tube nest, and a single standpipe or control column D connected by large diameter pipes D<1> D<2> with the steam and water spaces of each shell and having a single set of controls mounted' on its preferably flat walls for supplying feedwater to each shell and fuel to each burner. The supply of steam to a feed pump G<3> is controlled by a pilot G<1> actuated by steam controlled in dependence on float movements in a casing G connected to the steam and water spaces of the column. A main gas valve F<3> is closed by gas pressure in a pipe F<2> built up when a valve F is closed by excessive steam pressure in the collunn or a float-controlled valve F<4> is closed on a fall in water level, the gas otherwise escaping through a pipe F' into a space below the boiler. A flue damper H is controlled by means of gas pressure in a pipe H<1> so that when the main burner jets are out the damper is closed. The boiler shells are conveniently mounted on trunnions and disposed so as to be turnable into a horizontal position for removal of the tube nest &c., the burner being swung clear of the shell without breakage of any joints.

Title: Animated surface display device
IPC: G09F11/02
Filed: 1972-06-28
Abstract: 1390229 Animated display B A AMOURIQ 28 June 1972 [29 June 1971] 30312/72 Heading G5C Animated images displayed on each of two parallel composite surfaces A, B are carried on flexible sheets 15A, 15B which are moved in unison. Each sheet 15A, 15B has two horizontal portions and a vertical section in the plane of the surface A, B, respectively which section passes over guiding means 12A, 12B such as a slat, rod or tube. Each surface A, B is made up of these vertical sections. The sheets are interconnected and moved in unison over the guiding means so that the image displayed changes. One of the two horizontal portions of each sheet 15A is connected to a horizontal portion of a corresponding sheet 15B and to the adjacent horizontal portion of the sheet 15A immediately below it. The sheets 15B are similarly interconnected. One horizontal portion of each sheet is connected at its corners by straight connectors 20, and the other horizontal portion is connected at its corners by angled connectors 18, keeping the sheet under tension. The connectors 18 are fixed, on either side of the device, to a vertical rod 19 common to all the sheets. The rod 19 is fixed to blocks 21 which are screwthreaded on screws 22. The screws are rotated by a motor 27 or by a crank handle via chain 24 and sprockets 25 and 23, the latter being carried on the screws 22. Blocks 21 are moved along the screws and the sheets 15A, 15B move in unison over the guiding means 12A. Alternative means for moving the sheets (Fig. 11), comprise two vertical rollers 43 which are connected by flexible connectors 42A, 42B to the corners of the sheets 15A, 15B. As the rollers are rotated the sheets are moved. The device may be internally illuminated by tubes situated in the gap between the free edges of the sheets, the size of the gap being such that the sheets do not foul the tubes as the sheets are moved or by tubes located within hollow guiding means. The portions of the sheets not in the surface A or B need not be horizontal but can be inclined or almost parallel to the surfaces. Various modified ways of interconnecting the sheets are also described, e.g. the sheets of a surface may be formed from a continuous band, or a sheet 15A and the corresponding sheet 15B may be formed by a continuous band. A different guiding means is also disclosed (Fig. 9). The slats 12A are replaced by assemblies situated at each vertical side of the surfaces A, B. Each assembly consists of a series of projections 40 separated by slots and the sheet 15A passes over a projection and is engaged in the slots on either side of that projection. An overpressure may be provided in the case of the device, slightly inflating the sheets and reducing friction between the sheets and guiding means. The images may initially be formed on the sheets as the sheets are moved in the device, either by printing or by perforating the sheets.

Abstract: 1361023 Positioning apparatus GAF CORP 29 June 1971 [30 June 1970] 30482/71 Heading G4H [Also in Division H1] A switching device comprises a contact finger 60b wiping over a common contact 38 and a contact finger 60a wiping over ten "tens" contacts 40, 41 ... 49, and ten contact fingers 62a, 62b ... 62j, simultaneously wiping over ten "units" contacts 40-0, 41-1, 42-2 ... 49-9 integral with the "tens" contacts 40, 41 ... 49. Contact fingers 62a, 626 ... 62j are so arranged with respect to contact finger 60a that a finger 60a wipes over the length of one "tens" contact, each of the contact fingers 62a, 62b ... 62j wipes over one "units" contact, thus as the contact fingers are rotated, ten "units" contacts are engaged for each "tens" contact engaged. In general, the number of contact fingers 62a, 62b ... 62j, when multiplied by the number of "units" contacts equals the product often times the number of "tens" contacts. In the embodiment shown in Figs. 2 and 5 there are 100 contact combinations but in a second embodiment, Fig. 6 (not shown), two systems are combined so that one system gives 100 contact combinations and the other gives 80 contact combinations. The switching device is intended to select a particular slide from a rotary slide projector carrying 100 (or in the case of the second embodiment, 100 or 80) slides. Ten resistors 65a ... 65j are connected as shown in Fig. 5 and as the contact fingers 60a and 62a, 62b ... 62j wipe over the contacts, 100 different resistance combinations are made, the combination shown in Fig. 5 being combination 93, i.e. finger 60a is on contact 49 and finger 62e is on contact 43 (in actual fact it would be on 43-3 which is integral with contact 43) so that 100 resistance combinations are obtained with ten resistors. The resistors 65a ... 65j are connected to resistor banks 67, 68 in the slide projector which are varied as the magazine rotates. The magazine is driven by a motor and when this is switched on by a separate switch (not shown) and the switching device is rotated, the motor rotates the magazine until the resistance value in the projector is equal to the resistance value of the switch at which position the motor stops and the selected slide is opposite the projection gate. The contacts are rotated by a knob (13), Fig. 1 (not shown), or inched round one at a time by a button (23) (forward) or (24) (reverse) which when depressed cam pawls into engagement with a toothed wheel to which the moving contacts are joined. Detent button (20), Fig. 4 (not shown), retains the wheel in position. Simple spring contact (25), when depressed by a button (22), Fig. 1, actuates the circuit.

Title: Atomizer
IPC: B05B7/12
Filed: 1946-10-15
Abstract: 625,060. Nozzles with cut-off devices ; fluid-actuated valves. BAHNSON CO. Oct. 15, 1946, No. 30714. Convention date, Oct. 19, 1945. [Classes 69 (iii) and 135] An atomiser includes a water valve which is held closed by a spring against the water pressure but which is opened when compressed air is also admitted. The valve comprises a stem 14 secured to the rear of the casing and a seating 26 which, with sleeve 18 is free to slide over stem 14 under the influence of water pressure on diaphragm 8. Clearance between stem and sleeve enables water to reach the valve from the rear compartment. A second sleeve 19 which slides over sleeve 18 is connected to the air diaphragm 5 and also transmits the pressure of spring 3 to the rear diaphragm 8 through nut 31 which bears on a collar 23 on sleeve 18. The spring 3 is so adjusted that the pressure of water on diaphragm 8 will not move the sleeve assemblies forward against the spring. When compressed air is admitted at 9, however, the additional pressure sleeve to diaphragm 5 being larger than diaphragm 8 opens the valve. A pin 21 on stem 14 serves both to clean the jet 27 and to impart turbulence to the flow of water.

Title: Improvements in and relating to process of and apparatus for canning eggs
IPC: B01D29/23
Filed: 1934-10-26
Abstract: 438,233. Filters. STANDARD BRANDS, Inc., 595, Madison Avenue, New York, U.S.A. Oct. 26, 1934, No. 30729. Convention date, Feb. 13. [Class 46] Liquid whole eggs or the yolks or whites are prepared for canning by forcing the egg material out of a conduit 13 of relatively small cross-sectional area and through a filter 14 the effective surface area of which is many times greater than the cross sectional area of the conduit 13 against a back pressure greater than atmospheric, the porosity of the filter being such that the material is disintegrated and made homogeneous and freed from chalazµ, pieces of shell and foreign matter. As shown, the egg material is discharged from a hopper 10 through a conduit 11 to a gear pump 12 which disintegrates it and forces it into the conduit 13 leading to the filter 14 from which it passes upwards through a conduit 26 into a mixing and storage tank 27. The back pressure is derived from the weight of the column of material above that in conduit 13 and is governed by the depth of material in tank 27. The filter 14 consists of a casing 15 to one end piece 16 of which is screwed a member 18 which secures therein the filter member 19 formed of wire mesh. The filter member 19 is held in position by a bolt 23 extending through an end plate 21 thereon which is engaged by a wing nut 25 screwing on the bolt. The foreign matter separated by member 14 from the egg material collects on the interior of the wire screen and forms a filter bed which extends through to the other side of the screen. The member 19 can readily be removed for cleaning. The tank 27 has a mixing paddle 28 driven by a motor 29 and a valve 30 with an operating handle 31 is provided in conduit 26 to prevent back flow from the tank. A draw-off pipe with a cock is provided at the bottom of the tank. The pump 12 is driven through gearing from a motor 32.

Modulation applied to the base of a common emitter transistor VT1 with a capacitor C1 connected between its collector and base, varies the current gain and therefore effective (Miller) value of the capacitor C1 and as this shunts the frequency determining circuit C3, L3, C5, C6 of a transistor Colpitts oscillator VT2, frequency modulation is produced. A diode D in the bias network R1-R3 for the transistor reactance compensates against frequency changes with temperature. Alternatively an A.F.C. voltage may be applied between earth and the diode D, or a resistor replacing it, if a constant temperature oven is used. Output is derived from the oscillator through capacitor C9, from across emitter resistor R9. Resistor R8 limits the amplitude.

Abstract: 1,100,036. Air preheaters. CENTRAL ELECTRICITY GENERATING BOARD. 5 July, 1966 [20 July, 1965], No. 30869/65. Heading F4S. In an air preheater, pressurized air passing over upright ceramic tubes is heated by combustion gases at atmospheric pressure passing through the tubes and generated by an independent combustion system, each tube being formed in lengths with abutting flanges on the adjacent ends of two lengths. As shown, the tube lengths are arranged end-to-end with a spigot and socket connection 15 and with abutment flanges 13, 14 which may be coated with a viscous sealing material such as glass or quartz. A similar joint is formed between the lower end of the tube and a lower tube plate 22. The upper ends of the tubes pass through clearance holes in the upper tube plate 32 the seal being effected by a ring 30 slidable on the tube. The relatively high air pressure, e.g. six or seven atmospheres assists in maintaining the tube joint seals. The clearance hole in the upper tube plate is such as to permit passage therethrough of the tube section flanges 13, 14 for assembly purposes. The invention is intended for the preheating of combustion air in an M.H.D. generator plant, the air being preheated by the generator waste gases before passing to the recuperator tubes the hot gases for which are generated in a separate combustion unit (41, Fig. 2).

Filed: 1928-10-25
Abstract: 299,430. Veisse, S. Oct. 26, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Pumps, piston, preparing rich mixture in.--A small pump 5 driven at engine speed, on the outstroke of its plunger G, draws in first fuel from a controlled passage 18 and then air through the terminal port 22. On the up-stroke of the plunger the heat of compression vapourizes the fuel and partial combustion may take place. The vaporized fuel is delivered past the valve 4 into air compressed in the working cylinder 1, and either burns as it enters or is ignited by a sparking plug. As applied to a four-stroke-cycle engine a valve 20 is included between the controlled passage 18 and the pump fuel-inlet port; this valve is driven off the cam shaft 10 and admits fuel to the pump only on alternate outstrokes. The intermediate strokes are used to draw air only into the pump, which air after compression is used for scavenging. The pumps may be driven by eccentrics on the main crank-shaft, the pump cylinders being formed in the main casting. The pumps may be formed as a separate unit attachable to existing engines by removing the magneto and using the magneto driven shaft, to drive the pump shaft. Two plungers 6, Figs. 6 and 7, work in two cylinders and four delivery valves 4 are provided leading to the power cylinders. The crossheads 24 of the plungers are used as pumps into which air is drawn to be compressed slightly before delivery into the main pump compression chamber 5; the pump chambers 5 and crosshead chambers are cross-connected. The air may be heated by the resistance 26 before entering the pump.
