Patent GB-1254818-A (GB)
Title: Liquid level detector
Inventor: CLIFFGARD ARNIE L
IPC: G01F23/24
Filed: 1970-06-23
Abstract: 1,254,818. Liquid level indication. A. L. CLIFFGARD. June 23, 1970 [July 7, 1969], No. 30507/70. Heading G1H. In a liquid level detector, such as for use with automobile batteries, brake fluid level alarms, gasoline low level alarms, oil level low level alarms and water tank alarms, a thermistor 12 is normally immersed in liquid and cooled so that the potential at the junction 32 is high with respect to ground but when the liquid level falls to leave the thermistor 12 in a poor heat conductor, such as air, the thermistor 12 temperature rises and the potential at junction 32 decreases, to approach ground, until the potential becomes lower than junction 40 and the transistor 34 starts to turn off, the collector voltage to the transistor 34 rises and the current through a resistor 47 rises to bias a transistor 36 on and the feedback from transistor 36 to transistor 34 via resistor, 37 works against the impedance of resistor 38 and a Zener diode to turn transistor 34 off, and as a result a rapid toggle action occurs in which either transistor 34 or 36 is on and as a result if transistor 36 conducts, transistor 41 is saturated to close a series circuit to light a lamp 23 to indicate a low liquid level.

Title: Improvements in or relating to the manufacture of lithopone
IPC: C09C1/06
Filed: 1926-12-02
Abstract: 263,119. New Jersey Zinc Co., (Assignees of Hooey, W. C.). Dec. 15, 1925, [Convention date]. Pigments.-In the manufacture of lithopone, uniform products are obtained by determining the end point of the reaction between the zinc sulphate and barium sulphate solutions by the amount of hydrate and/or sulphydrate present in the crude pulp. The results obtained depend on the excess of and ratio between the hydrate and sulphydrate radicals in the crude pulp, and this excess and ratio may be arbitrarily chosen. The ratio of hydrate to sulphydrate radicals in the barium sulphide liquor itself may be controlled by the addition of barium hydrate or sulphuric acid. The hydrate content of the liquor is increased by producing the barium sulphide from barytes of high iron or manganese content, by using moist charge in the baryte furnace, or by utilizing the later leaches of the black ash (baryte furnace product). The excess and ratio of the radicals referred to, in the crude pulp in the precipitating tank, may be finally controlled by the addition of barium or other hydrates, such as those of calcium, magnesium, or sodium. Specification 263,120 is referred to.

Title: Improvements in or relating to storage water heaters
Inventor: SOLEY MICHAEL JOHN NEWEY
IPC: F24H1/20
Filed: 1960-09-05
Abstract: 914,988. Delivery arrangements for water heaters. MAIN WATER HEATERS Ltd. Aug. 23, 1961 [Sept. 5, 1960], No. 30573/60. Class 64(1). In a storage water heater having a syphon outlet formed by a cap 31 mounted over the top of an outlet pipe 26, and a pipe 29 which vents the space above the water level to atmosphere, the vent pipe is provided at its lower end with a calibrated orifice 34. The diameter of the latter is so chosen that when a valve 19 is opened to admit cold water to the vessel through an inlet 17, the increase in air pressure in the upper part of the vessel causes the water level to rise more quickly within the cap 31 than in the vessel; thus the syphoning action is initiated more quickly and the water level within the vessel is quickly reduced to the level of the lower edge of the cap 31 at which point the rates of inlet and outlet flow of the water become equal. The water is electrically heated and the upper part of the vessel may be shaped to provide a pocket into which the vent pipe and cap extend. The calibrated orifice 34 may be removable and/or adjustable.

Filed: 1975-07-24
Abstract: 1521732 Hydraulic power systems INTERNATIONAL HARVESTER CO 24 July 1975 [24 July 1974] 30995/75 Heading B7H The hydraulic power system of a vehicle comprises: a primary hydraulic circuit supplying a control valve 4 for use in steering the vehicle; a secondary hydraulic circuit supplying a control valve 6 for use in operating an implement accessory of the vehicle; a spool valve 15 having an inlet port 18, a first outlet port 24 for providing a fluid flow to the control valve 4, and a second outlet port 25 which, in at least one working condition of the system, provides a residual flow through a line 38 to the secondary circuit; and a spool valve 26 actuated by pressure of fluid in the secondary circuit and arranged to act such that if the pressure in the secondary circuit falls below a predetermined value any residual flow through the line 38 is terminated. The system is intended to ensure that in the event of pressure loss in the secondary circuit, caused, e.g. by a line failure in the secondary circuit, a sufficient supply of fluid is delivered to the steering control valve 4. In the embodiment of Fig. 1, a motor 10 drives pumps 2, 8. The system is shown in its normally operating condition in which the pump 2 provides both a flow from outlet port 24 of spool valve 15 to control valve 4, and a residual flow from outlet port 25 of spool valve 15 to the secondary circuit. In the event of pressure loss in the secondary circuit, pressure in a signal line 28 connected to actuation chamber 27 of spool valve 26 drops and spool 54 of spool valve 26 moves to a position in which fluid flow from a line 22 to an actuation chamber 23 of spool valve 15 is terminated. The pressure in actuation chamber 23 consequently drops and the spool of spool valve 15 moves to a position in which the entire quantity of fluid flowing into inlet port 18 flows through outlet port 24 to the control valve 4. In the embodiment of Fig. 2, a motor 10 drives pumps 2, 8, and 33. In the illustrated condition of the system, the output of pump 33 is added to the output of pump 2 and flows to the control valve 4. The spool of spool valve 15 is moved as the speed of motor 10 increases to supply a portion, or the whole, of the output of pump 33 as a residual flow through line 38 to the secondary circuit. In the event of pressure loss in the secondary circuit, the pressure in signal line 28 connected to actuation chamber 27 of spool valve 26 drops and spool 54 of spool 26 moves to a position in which any residual flow from spool valve 15 is directed through a line 39 to a return line 37 of the primary circuit.

Title: Improvements in plastic compositions
IPC: C08F279/02
Filed: 1958-09-30
Abstract: A high-impact strength plastic material comprises a binary blend of (A) a graft polymer of a styrene monomer upon a polybutadiene rubber and (B) a resinous styrene polymer, the graft polymer being made by polymerizing the styrene in a latex of polybutadiene which contains from 0 to 1.0% of divinyl benzene, has a gel content of at least 75% and has a swelling index greater than 11, the proportions of styrene monomer to polybutadiene being from 20 to 150 parts of the former to 100 parts of the latter, the intrinsic viscosity of (B) being at least 0.5 and the proportions of (A) and (B) being such that the blend contains 15 to 35% of polybutadiene.  The styrene used for grafting upon the polybutadiene may be styrene itself or alpha-methyl styrene or a vinyl toluene or mixtures thereof; similarly, the resinous polymer may be derived from styrene alone or alphamethyl styrene or vinyl toluene or mixtures of two or more of such monomers. The graft polymerization of the styrene upon the polybutadiene is effected with the aid of emulsifiers, catalysts and mercaptan regulators of known types.  The graft polymer and the resinous polymer may be blended together in the dry state or latices of the two polymers may be mixed and co-coagulated, but in either case the blend is subsequently mechanically-worked at a temperature high enough to plasticize the mass.  Specification 726,583 is referred to.
