Title: An apparatus for automatically dispensing a predetermined amount of a liquid
IPC: G01F11/44
Filed: 1958-08-18
Abstract: 886,742. Delivering measured quantities of liquids. TARUKAWA, T. Aug. 18, 1958 [Aug. 27, 1957(2); May 19, 1958], No. 26521/58. Class 106(5). Apparatus for delivering measured quantities of liquid comprises a measuring tank 1 with an inlet valve 31 and outlet valve 41, both of which are electrically-operated, and operation of a pushbutton switch P opens the outlet valve and, after discharge is complete, the outlet valve is automatically closed and the inlet valve opened so that the tank refills, ready for the next operation. As shown in Fig. 1, closure of the switch P energizes an electromagnet M6 and a switch lever 5 is changed over so that a switch S2 closes and energizes an electromagnet M4 to open the outlet valve 41. As the level of liquid in the tank falls, a float 2 opens a switch S1 in the circuit of time switch T1 and electromagnet M2 for the inlet valve and, after discharge is complete, a time switch T2 energizes an electromagnet M5 so that the switch lever 5 is returned to its previous position. A switch S3 then closes, an electromagnet M3 is energized to close the outlet valve and an electromagnet M1 is energized to open the inlet valve. When the rising liquid level raises the float 2, the switch S1 is closed to energize the electromagnet M2 for closing the inlet valve and then a time switch T3 de-energizes the electromagnets M1 and M3 and the time switch T1 de-energizes the electromagnet M2. The inlet and outlet valves may be combined at the bottom of the tank and the float, in its lowest position, may perform the function of the time switch T2. To vary the amount measured, the position of the float may be adjustable. In a modification, the function of the electromagnets M5, M6 and time switches T1, T3 may be performed by arranging the switches S2, S3 to be operated by the movement of the arms 43 of the outlet valve and, in a further modification, the float 2 and time switch T2 may be replaced by two pairs of spaced electrodes, one pair at the bottom and one pair at the top of the tank, the top pair of electrodes being short-circuited by the liquid to control a solenoid-operated switch for closing the inlet valve and the bottom pair being open-circuited when discharge is complete to close the outlet valve. In the modification shown in Fig. 3, the outlet valve operating arm 43 is moved by a reversible motor M which is controlled to start in one or other direction by switches MS1, MS2 and is stopped by the arm operating switches S4, S5 and the inlet valve is controlled by a switch S6 operated by electromagnets M9, M10. In a further modification, of the circuit shown in Fig. 1, the time limit switch T2 is removed, a circuit is provided between the electromagnets M2 and M6 and the pushbutton switch P controls the electromagnet M5; with this circuit, when the pushbutton is pressed, liquid flows into the tank to a predetermined level and is then automatically discharged.

Abstract: 482,139. Liquid-fuel burners. DICA, SOC. ANON. DE BRULEURS ET INTERRUPTEURS AUTOMATIQUES, PULEJO, C., and STAUB, J. Oct. 1, 1936, No. 26677. [Class 75 (i)] A liquid-fuel burner mounted in a casing 2, Fig. 2, secured behind the diffuser shown in Fig. 1, comprises a block 7a carrying an adjustable nozzle 7, a tubular needle 4, and an adjustable valve 5 threaded in a stuffing box 10 on the needle 4. Liquid fuel is supplied through passages 9 to the tubular needle 4 and an atomizing agent such as air is supplied through a duct 8 to the nozzle 7, both being whirled on discharge by vanes 6a, 6 on the valve spindle and needle. Withdrawal of the valve from the nozzle 7 causes an increased discharge of air and a smaller discharge of fuel. Additional air is supplied to the burner by suction past adjustable baffle devices 15, 16 in the diffuser and casing, the tortuous air paths reducing the noise of combustion. Some of this air passes through a cone 11 on the nozzle 6 and produces a suction at the sparking plug 13 to facilitate ignition. An aperture 20 in the casing 2, normally covered by a resilient metal band allows access to the burner for adjustment. The valve 5 may be operated between abutments corresponding to maximum and minimum fuel supply through a linkage 25 by two electromagnets 22 controlled by a thermostat.

Title: Improvements in or relating to the production of mouldings made of non-metallic substances
IPC: B29C43/18
Filed: 1959-08-05
Abstract: 879,404. Compression-moulding machines. REGIE NATIONALE DES USINES RENAULT. Aug. 5, 1959 [Aug. 14, 1958], No. 26822/59. Class 87(2). Fibrous reinforcement 1, in sheet form, is laid in the cavity of a mould 2 and liquid resin 10 is spread on it. A plunger 3 carries a cutter 4 surrounded by a resilient gasket 6 which presses the reinforcement 1 on the portion 8 of the mould before the interaction between the cutter 4.and a counterblade 7 takes place, so preventing the reinforcement from being rammed in the bottom of the cavity. At the end of the stroke, determined by an adjustable stop 5, the gasket is flattened and recesses 9 therein are therefore closed, rendering the mould fluid-tight. In the closing movement of the punch the recesses 9 alter in size and shape, due to the resilience of the gasket, in proportion to the distance between the punch and the die, resulting in even distribution of the liquid resin due to controlled venting of the air pressure. The cutter trims the excess overlapping edge of the sheet 1.
