Title: Improvements in or relating to apparatus for stacking or unstacking plates, sheets or other flat articles
Inventor: LAMB HAROLD WENDELL
IPC: B65H1/18
Filed: 1961-08-11
Abstract: 999,152. Feeding and delivering sheets. CROSSLEY MACHINE CO. Inc. Aug. 11, 1961, No. 3424/65. Divided out of 999,151. Headings B6B and B6H. [Also in Division B8C] Sheets T are delivered to or fed from a platform 16 movable vertically by a piston 30. The latter slides in a cylinder A. The lower end of said cylinder is connected to a well W, containing liquid O, through a valve V3. The tops of the cylinder and well are connected to a compressed air source or the atmosphere through three-way valves V4 and V5. A pivoted feeler S4a engaging the top of the stack, actuates a switch S4 whenever a sheet is delivered to or fed from the platform. Said switch S4 controls the valve V3, whereby the platform is raised or lowered. The platform actuates switches S7 and S8 at the limits of its movement. For receiving sheets, initially the platform is in its uppermost position with the valves V4 and V5 in communication with the compressed air source and atmosphere, respectively, and the valve V3 closed. The valve V3 is opened each time a sheet is delivered to the platform under the control of feeler S4a, and associated switch S4, whereby the platform is lowered until the feeler is restored to its original position. This continues until the stack is completed and the switch S7 operated by the platform. For feeding sheets, initially the platform is in its lowermost position with a stack of sheets thereon. The valves V4 and V5 are in communication with the atmosphere and compressed air source, respectively, and the valve V3 is closed. The valve V3 is opened each time a sheet is fed from the platform, under the control of feeler S4a and associated switch S4, whereby the platform is lifted until the feeler is restored to its original position. This continues until the stack is exhausted and the switch S8 operated by the platform. Said switch returns the platform to its lowermost position to receive a fresh stack.

Title: Improvements in or relating to gas turbine plants
IPC: F02C7/14
Filed: 1944-02-28
Abstract: 572,194. Air and gas cooling installations. STRUB, R. Feb. 28, 1944, No. 3692. [Class 64 (iii)] [Also in Group XXVI] A gas turbine plant includes two coolers, through which the working fluid passes in the course of a circuit, the heat abstracted being utilised externally. In the figure, exhaust gas from a turbine 4 passes through a heatexchanger 2 where it heats up gas and/or air being delivered from a compressor 1 and a " make-up " compressor 5 supplying air from the atmosphere. The plant may be modified to use the working medium on a closed circuit. Part of the compressed fluid from 2 flows through a pipe 30 into a heater 3 and then passes into the turbine 4. The other part of the compressed fluid passes as combustion air through a pipe 31 to the burner of the heater 3 and the resultant gases supply a turbine 6 driving a propeller 8 through gearing 7. The exhaust gases of 6 are used in a boiler 16. As shown, the compressor 5 introduces air to the circuit at a point at which the working fluid flowing back from the turbine 4 is at approximately the same temperature as that of the make-up air. The exhaust from 4 passes through two coolers 9, 10 and on its return to the compressor 1. Cooling medium from 9 passes through a pipe 15 into the boiler 16, into a pipe 17 and the heat is utilised in heating elements 23 and a sea-water evaporator 24. A pump 26 returns the coolant to 9. A by-pass pipe 25, including an additional cooler 21, is controlled by a thermostat 18. The thermostat also controls the fuel supply to a burner in the boiler 16. If the temperature of the' coolant in 17 is too low, the burner in the boiler is brought into action, or, if in action, the fuel supply is increased. If the temperature of 17 is too high, the fuel supply to 16 is decreased or cut off, and the cooler 21 brought into action. Coolant for the cooler 10 is supplied by a pump 11, and after use is discharged. Sea water may be used for 10, and also for the cooler 21. The temperature of the water leaving 10 is regulated to be below 50‹C. to prevent deposition of salts in the cooler. The exhaust gases from the turbine 6 may be used to assist driving the compressor. The cooling of the gases in the boiler should not be to a temperature lower than the dew point.

Abstract: 804,525. Clutch control. FICHTEL & SACHS A.G. Feb. 9, 1955 [March 24, 1954], No. 3819/55. Class 80 (2). On a vehicle wherein, during gear shift by the usual manual lever 62, a main speed-respsionve clutch 11 is disengaged by a power cylinder 17 communicated with the engine inlet manifold 25 through ducts 22, 24 including a solenoid valve 23 energized (position shown), by a shiftlever-operated switch, the same valve 23 also applies engine suction 24 through a restrictor 47 to a spring-loaded diaphragm 40 which acts adjustably on an arm 32 on the engine throttle spindle 30 to ensure that, even if the accelerator pedal is released during gear-shift, the throttle 29 is automatically opened, as shown, sufficiently to raise the engine speed above that minimum necessary to engage the speed-responsive clutch 11, so that when, on completion of gear shift the power cylinder 17 is de-energized by the valve 23, the clutch re-engages solely under control of the power cylinder 17 which vents through an adjustable outlet 52. There is an adjustable turnbuckle 20 in the link to the clutch lever 15. The speed-responsive main clutch may be centrifugal, or generator-voltagecontrolled electromagnetic, or be operated by vacuum, pressure air or liquid, or electric servomotor. Specification 767,864 is referred to.

Abstract: 627,535. Liquid-fuel burners. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Feb. 10, 1947, No. 3849. Convention date, June 6, 1944. [Classes 75(i) and 75(iii)] A liquid fuel burner comprises a rotating atomiser cup surrounded by an air nozzle the full working supply of which directs atomised spray from the cup clear of a spark gap between fixed igniting electrodes during normal operation of the burner but at starting up the air supply is reduced so that the spray is no longer diverted to the same extent but extends to the spark gap. A rotating atomiser cup 1 arranged within an air supply nozzle 2 is surrounded by a fire proof cylinder 3 the radiant heat of which assists in the evaporation of the atomised fuel, such cylinder carrying ignition electrodes 5, 6 connected to a high tension electric supply. At starting the air supply to the nozzle 2 is limited by the inertia of a flywheel on the fan supplying the air or by means of a valve in the air supply passage which preferably opens automatically when ignition takes place, the limited supply,of air being unable to direct the spray of fuel forwardly clear of the ignition gap. An opening 9 is preferably formed in the back wall 4 of the combustion space to allow air to flow over the electrodes 5, 6 to burn carbon deposit thereon.

Title: Improvements in devices for mixing fluids
IPC: G05D23/13
Filed: 1943-03-11
Abstract: 567,799. Mixing fluids. McMEEKIN, J. S., and McNAMEE, J. J. March 11, 1943, No. 4014. [Class 64 (i)] A device for mixing two fluids, e.g. steam, or hot water, and cold water, comprises essentially a mixing chamber M, Fig. 1, in the form of narrowly spaced walls 21, 22 to which the steam and cold water are led from inlets 12, 13 and through a nozzle part 18 and annular passage 24 with discharge port 25 respectively, the flow of steam through the said nozzle 18 being controlled to regulate the temperature of the resultant hot water at the outlet 14 of the device by a guide 20 which coacts with the nozzle part 18 to form a valve and is actuable by a handle 15 and by an associated thermostat 28, 29 located in a casing 10 between the chamber M and its outlet 14. As shown, the nozzle 18 is of convergent form and is surrounded by the passage 24 and port 25, the arrangement being such that the steam from the nozzle will be spread into a thin sheet in the mixing chamber and the cold water entrained by and interspersed therewith, the resultant hot water passing through ports 26 at the periphery of the mixing chamber and through the casing 10 past the thermostat to the outlet 14. The thermostat comprises three superposed sets of radially-arranged bimetallic bent strips 28, 29 of M-form in section, each set consisting of four quadrantal pieces, Fig. 3, and each quadrant being separated from the next by a radial slot 31 and itself divided by two narrow radial slots 30. The uppermost strip 28 is secured to an axially-adjustable, non-rotatable nut 39, the lowermost strip 29 to the valve 20, and the intermediate strips to interlocking nut units 34, 35, the latter units and the guide or valve 20 being slidably mounted upon a rod 36 depending from a screw 37 which is rotatable by the handle 15, but locked against axial movement by a projection 38. In operation, rotation of the handle 15 and screw 37 will effect axial movement of the nut 39, strips 28, 29 and valve 20 towards or away from the nozzle 18 to regulate the flow of the, steam, this hand control being subsequently influenced by the thermostat if the temperature of the water in the casing 10 rises or falls relatively to the temperature for which the handle 15 is set. In a modification, Fig. 6, for use where the water supply is at atmospheric or a lower pressure, the water is led to an annular chamber 54 which is located on the side of the valve 51 opposite to the nozzle 50 and is provided with a nozzled outlet 55 having a rapidly flowing divergent outlet 57 and a seating surface 58 for co-operation with a surface 52 on the back of the valve 51, the outlet 57 forming a suction zone S and the surfaces 52, 58 constituting a valve for the water supply which opens or closes when the steam valve 50, 51 closes or opens respectively.
