Title: Improvements in or relating to voltage stabilisers
IPC: H04N5/63
Filed: 1963-10-10
Abstract: 1,011,188. Voltage stabilizers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct. 10, 1963 [Oct. 13, 1962], No. 40018/63. Heading G3X. A load 50 is supplied from a voltage source U, having an internal resistance 12, by way of a radiating element 3 and a radiation-sensitive resistor 4; variations in load current cause corresponding variations in the radiation emitted by the element 3, and hence corresponding variations in the resistance of the resistor and which is responsive to radiation received from the element 3. The arrangement is such that when the load current increases, the increase in voltage-drop across the internal resistance 12 is compensated for a concurrent reduction in voltage across the radiationresistor 4, whereby the voltage across the load is maintained substantially constant. The element 3 may be a neon tube or a light radiating pn diode, and the resistor 4 a cadmium sulphide cell. A mask may be arranged between the elements 3 and 4. A resistor or a capacitor may be connected in parallel with the resistor 4, and a resistor may be connected across the output of the arrangement to prevent an excessive voltage increase across the load in the absence of a load current.

Title: Improvements relating to apparatus for delivering measured quantities of liquid
IPC: C02F1/68
Filed: 1948-02-17
Abstract: 635,874. Delivering measured quantities of liquid. PERMUTIT CO., Ltd. (Permutit Co.). Feb. 17, 1948, No. 4660. [Class 106(v)] [Also in Group XXVIII] An apparatus for delivering measured quantities of liquid from a storage vessel comprises a measuring tank placed above the storage vessel and having an inlet connected to the storage vessel and at a lower level a valved outlet pipe through which liquid drawn from the storage vessel can be discharged, a vacuum-producing device connected to the measuring tank, and a loop seal having one leg connected to the vacuum-producing device and the other to the atmosphere and operative to break the vacuum in the measuring tank when more than the desired measured quantity has been drawn into the tank but before the tank is full so that liquid above the inlet from the storage vessel will then drain back to the storage vessel, and thereafter the measured quantity of liquid can be discharged by opening the valve in the outlet pipe. Strong acid from a storage vessel 16 is drawn up, by suction from an ejector 22 and pipe 21, through a pipe 17 into a measuring tank 18 from the bottom of which leads a U-shaped outlet pipe 27, 28, 30 closed by a diaphragm valve 29. The acid rises under the suction up into a riser 20 at the top of the measuring tank 18 until acid in a U-seal 33, 34, which is open at 38 to the atmosphere and is connected by a pipe 32 to the riser 20, is sucked into the riser, whereupon the vacuum is broken and acid in the riser and tank 18 flows back into the storage vessel 16 until the level falls to the opening of the pipe 17 into the tank 18. The suction pump 22 is then stopped and the diaphragm valve 29 opened to allow the acid to discharge from the tank 18 through pipes 27, 28, 30, U-seal 33, 34 and outlet 36 into a dilution tank 15 to which at the same time water from a pipe 46, 51 is being added. Valves controlling the diaphragm valve 29, the ejector 22 and the water supply to the pipe 46 are operated by a motor which also drives a control mechanism 3 driving a valve 2, but may also be hand operated. Water from the pipe 46 may be shut off by a float controlled valve 49 when a certain level in the tank 15 is reached. A suction ejector built in the valve mechanism 2 sucks up dilute acid from the tank 15 through a pipe 14 at a certain point in the operation of the valve mechanism 2, the valve controlling the water supply to the pipe 46 and the diaphragm valve 29 being closed. Liquid is sucked up the pipe 14 for a predetermined time but a float valve may be provided to stop the flow into the pipe 14 when a predetermined quantity of the dilute acid has been withdrawn from the tank 15. The float valves controlling the flow into and out of the tank 15 may be replaced by electrode operated valves.

Abstract: 604,428. Batteries. GENERAL ELECTRIC CO., Ltd., and SANDERSON, R. W. W. March 17, 1944, Nos. 5001 and 17291. [Class 53] The electrolyte of a cell of the inert type is formed as a layer on one or both sides of a paper or other porous sheet 11 placed between the zinc cup 10 and dolly 15 which is spaced from the bottom of the cup. The electrolyte may consist of ammonium chloride and mercuric chloride mixed with a binder such as gum tragacanth. In making up the cell the electrolyte-coated sheet 11 is first placed in position in the zinc cup and then a quantity of sand 13 is introduced upon which the dolly 15 is stood. The sand forms a firm foundation for the dolly during the subsequent operations of capping and washering. When the cell is required for use a hole is made in the bottom or side of the zinc cup and the sand allowed to run out. Water is then introduced through the hole. In another method of making up the cell a hole is made in the bottom of the zinc cup before assembly and the cup placed, over a tapered plug 17 carried by a base plate 18 as shown in Fig. 2. A cardboard tube 19 surrounds the plug 17 on which the dolly rests. The cell, or battery as shown, is then surrounded by a cardboard casing which is filled with composition 21 such as a mixture of beeswax and paraffin wax. The plate 18 and temporary spacers 20 are then withdrawn. In another method the filling holes are made in the sides of the cup and closed by tapered plugs which are removed after the cell has been surrounded by the composition 21. The cells may alternatively be assembled upside down the bottoms being pierced with holes which are closed by cardboard discs. Pitch is poured over the cell bottoms to form a thick layer which is allowed to set. Holes are then drilled through the pitch and cardboard discs. The holes in the composition may be reinforced by tubes of steatite or other material.
