Title: Improvements in weighing scales
IPC: G01G13/32
Filed: 1933-08-24
Abstract: 409,554. Automatic - feed weighers. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Toledo Scale Manufacturing Co. ; Toledo, Ohio, U.S.A.) Aug. 24, 1933, No. 23539. [Class 143.] In a weighing scale for weighing successively predetermined amounts of ingredients into a container from a plurality of storage and delivery systems, a plurality of electricallyoperated devices co-operate with the weighing mechanism to control the material feeding means, an electric circuit is provided for each of the electrically-operated devices, and a selector device is provided for selectively bringing a photo-sensitive element into controlling relation with each of the circuits. The weighing scale shown is adapted for filling a series of containers 39 with predetermined amounts of two liquids contained in tanks 40, 41. In the normal, unloaded position of the weighing mechanism the pendulums 14, 15 are situated in their maximum load-counterbalancing position, the position of the indicating pointer 19 thus coinciding with the zero position. When an empty container is placed on the platform, the pointer moves in counterclockwise direction and the pendulums descend, but the original position is restored by adjusting a tare poise at the rear of the machine. A poise 28 is now moved to indicate on its beam the desired weight of the first ingredient, namely from the tank 40. The movement of the poise causes a corresponding counterclockwise movement of the pointer 19 and unmasks a slit in the dial so that a beam of light passes through, to a photoelectric cell connected to an amplifier and relay, thus closing the relay. The relay is connected to the mains through a push button switch and through a solenoid for opening the valve 44. The operator now presses the push button switch and the liquid flows into the container until, when the predetermined weight has entered, the returning pointer cuts off the beam of light to the photoelectric cell, re-opening the relay, de-energizing the solenoid and allowing the valve to close under spring action. The second liquid, from the tank 41 is similarly weighed into the container by first setting a poise 27 to the required weight and by switching-over the relay and photoelectric cell, by means of a hand switch, to a second electric circuit in connection with a second valve 45, a similar operation then taking place to complete the weighing.

Title: Improvements in ram-jet engines for aircraft and in particular for supersonic aircraft
IPC: F02K7/10
Filed: 1955-08-18
Abstract: 782,396. Jet-propulsion plant. ZBOROWSKI, H. P. G. A. R. VON. Aug. 18, 1955 [Aug. 20, 1954], No. 23775/55. Class 110 (3). [Also in Group XXXIII] A ram jet has a variable area propelling nozzle controlled by means responsive to the difference in static pressures on the inside of the inlet diffuser and on the outside of the engine so that this difference remains substantially constant. The ram jet shown has a casing 1 formed as a body of revolution containing two annular burners 2. The casing may constitute the main supporting aerodynamic surface of the aircraft. The area of the propelling nozzle 3 is controlled by spoilers 4 actuated by a servomotor 14 through a link 15. The servomotor 14 is controlled by a detector comprising a box having a diaphragm 8 which divides it into two chambers connected by passages 9, 10 with the inside of the inlet diffuser 7 and the outside of the engine respectively. The diaphragm 8 carries an insulating button 11 capable of closing either of two electric switches 12, 13 which energize the servomotor 14. Closing of switch 12 due to reduction of pressure in the diffuser 7 causes a throttling of the propelling jet and closing of switch 13 causes an increase in the crosssection of the jet. The contacts 12, 13 may be mounted on a movable support controlled by a machmeter or a device responsive to the static pressure or the translational speed of the engine or both so that the control only acts above a given static pressure difference, the value of which varies with these engine operating conditions. A second control system may be provided to act independently on the spoilers 4 to produce a deflection of the jet. In a modification, the area of the propelling jet is varied by controlling air passages through the casing 1. If desired, the area of the propelling nozzle, may be varied by pivoting shutters or by introducing air under pressure into the jet, which air may be supplied by a special compressor, by another engine on the aircraft such as a turbojet, or turbo-propeller engine, or by the air flow through the ram jet.

Abstract: 785,358. Fire-extinguishing. PYRENE CO., Ltd. Aug. 23, 1954 [Sept. 2, 1953], No. 24301/53. Class 47 [Also in Group XXIX] In a fire extinguishing system in which a battery of containers 11 supplies gas to one of two or more risks A, B through pipes 27 and nozzles 28, the gas passes through distributing valves 10 one of which is associated with each risk and is opened by gas released manually or automatically from a container 8, this gas subsequently operating a release mechanism of the container 11. Each valve 10 comprises a spindle 14 carrying pistons 12, 13 and an extension 16 carrying pistons 17, 18. When gas from a container 8 is supplied to an inlet 19 through a pipe 9, the spindle is raised to open the passage between inlet pipe 26 and outlet pipe 27, and to allow gas to pass from inlet 19 to outlet 20 and by pipe 23 to the release mechanism of the containers 11. As shown, Fig. 1, the container 8 is opened by a weight 4 controlled by fusible elements 5. In a modication, Fig. 3, the containers 8 are replaced by a single end container 41 of the battery 40 and opening of the container 41 is effected by one of a number of weights 43 which also opens a corresponding valve 45 to supply gas to the corresponding distributing valve 10. The pipe 64 through which gas passes to open the containers 40 includes a non-return valve 67 so that when gas is supplied in the direction X all the containers are opened, but when supplied in the direction Y only some of the containers are opened to meet the risk concerned.

Title: Mechanically operated press
IPC: B30B1/14
Filed: 1955-08-24
Abstract: 811,999. Toggle presses. LAEIS-WERKE A.G. Aug. 24, 1955 [Sept. 11, 1954], No. 24403/55. Class 87(2). [Also in Group XXII] A toggle press which imparts a preliminary pressure followed by a main pressure has a hydraulic buffer with a valve for limiting the main pressure and, in addition, a valve for limiting the preliminary pressure with means for closing the feed thereto. When the crosshead 13 descends on the pressure stroke the die 14 encounters resistance and a piston-like part 18 extending upwards from it exerts pressure on oil in a chamber 15. A valve cone 20, on the end of a reciprocable shaft, is then open and oil flows past it until the pressure rises high enough to move a valve cone 27, slidable on the shaft, off its seating against a spring 23, whereon the part 18 enters the chamber 15 and forces oil therefrom into a reservoir 30. As the die 14 continues to descend it thus exerts a preliminary pressure until it reaches a point where a limit switch is operated and energises an electromagnet 21 to move a lever 22 to close the valve 20. The hydraulic resistance to the movement of the part 18 is thus increased and the die continues its descent until it exerts the maximum pressure, a limit to which is set by a valve 25 which opens against its spring and allows more oil to flow into the reservoir. When the crosshead rises a spring 16 returns the die 14 and part 18 to their lowest position and oil is therefore drawn from the reservoir, past a valve 26, refilling the chamber 15. The press described is toggle-operated from a motor-driven crank, the end of one toggle link 8 pivoting on a fixed pivot 9 and the end of the toggle link 10 pivoting on a pin 11 passing through the bottom end of a tie rod 12 connected to the crosshead, there being two toggles and two tie rods.
