Abstract: 1,235,366. Alkali metal perborates. SANDOZ Ltd. 15 Nov., 1968 [23 July, 1968], No. 54369/68. Heading C1A. Alkali metal perborates are produced by oxidizing an organic compound, which contains at least two hydrogen atoms oxidizable with the formation of hydrogen peroxide, in an organic solvent and reacting the oxidation mixture so obtained subsequently or simultaneously with a solid alkali metal borate and/or perborate in the presence of water, less than 0À6 mole of alkali metal borate being used per mole of the active oxygen initially present or theoretically obtainable by oxidation. Suitable organic compounds specified are hydrazo compounds e.g. hydrazobenzene, aminophenols, hydroquinones e.g. 2 - alkylanthrahydroquinone, secondary alcoholes e.g. isopropanol or cyclohexanol. Suitable solvents include alcohols, ethers, esters and ketones, or mixtures of these and hydrocarbons. The preferred starting material is an alkali metal metaborate e.g. sodium metaborate, disodium tetraborate, or a mixture of sodium metaborate and sodium perborate containing less active oxygen than the intended product. The preferred reaction temperature range is 10-60‹ C. and the process may be carried out on the countercurrent principle. The alkali metal perborates may be used as a detergent or bleaching agent.

Abstract: 1,253,926. Hydraulic gear pumps and motors. PARKER-HANNIFIN CORP. Nov.7, 1969, No.54666/69. Heading F1F. A hydraulic gear pump (or motor) comprising a three-part housing 2, 3, 4, Fig. 1, forming a pumping cavity 5 rotatably mounting a pair of intermeshing gears 6, 7 and a thin flexible wear plate 27 whose front face abuts a side face 21 of the gears and whose rear face is abutted by a seal assembly comprising a channel section annular seal 39, a gasket 40 and a heat shield 41 having compartments 35, 36, Fig. 5, communicating through openings 51, 50 in the wear plate with the low and high-pressure zones of the pump respectively and compartments 37, 38 communicating through holes 52, 53 in the wear plate with intermediate pressure zones of the pump includes a thin flexible thrust plate 28 located in a recess in the housing part 3 between the other side face 22 of the gears and an adjacent face 26 of the housing part. The thrust plate 28 is formed around its periphery with a relief 60, Fig.2, which except for radial projections 61 locating the thrust plate 28 in its recess is continuous from the pump outlet 20 to approximately the middle of compartments 37, 38. The relief 60 directs pump discharge pressure to compartments 36, 37, 38 so that the wear plate over compartment 36 and portions B 2  of compartments 37, 38 is pressure balanced and over portions B 1  of compartments 37, 38 is slightly over balanced, i. e. , the wear plate is pressed against the gears. The thrust plate also has a relief 62 and vent grooves 75 extending circumferentially 76 and radially 77. The relief 62 directs pump inlet pressure through opening 51 into compartment 35 so that adjacent the inlet port 18 the wear plate is pressure balanced and up to the commencement of compartments 37, 38 slightly under balanced, i.e., the wear plate is pressed against the housing part 2, so that friction and wear on plate 27 is reduced. The vent grooves 75 relieve any pressure build-up from leakage from behind the thrust plate 28. Under pump pressure the thin and flexible thrust plate is deflected into the vent groove 75 to permit a thin film of fluid to act as lubricant between the plate and the gears. Leakage fluid escaping along shafts 9, 8 is vented to the pump inlet 18 via a housing passage 101 and a bore 102 on the shaft 8. A non-return valve 105 closing the bore 102 ensures maintenance of a pressure in the chamber 12 behind the seal 13 above atmospheric to prevent air and foreign matter from being drawn into the pump.

Abstract: 1298464 Viscosity pumps PPG INDUSTRIES Inc 28 Nov 1969 [29 Nov 1968] 58194/69 Heading F1C [Also in Division F2] A two-stage liquid pump comprises relatively rotatable elements 10, 12, of which 10 may, as shown, be a rotor while 12 may be a stator. Molten glass to be pumped enters the first stage via inlets 20, Figs.1 and 3, and is dragged from each inlet 20 by the moving surfaces 22 of the rotor 10 so as to pass via a restricted clearance 24 to a cavity 26 which merges with an inlet cavity 32, Figs.1 and 5, of the second stage,  excess flow passing via a more restricted clearance 28 to the next inlet 20. In the second stage, molten glass is dragged from each inlet cavity 32 via a restricted clearance 34 to an outlet cavity 36. The radial depth of the clearances 24 is large enough to allow bubbles to pass, while the radial depth of the clearances 34 is less to provide a higher pressure and to exclude the bubbles. Bubble-laden molten glass is removed via a passage 40 and a drive coupling 16. Bubble-free molten glass is discharged from the outlet cavities 36 via ducts 42 and a central bore 44. Wedgeshaped bearing chambers 50, 52 are supplied with molten glass from the cavities 26, 36, the molten glass acting as a lubricant and serving to maintain the alignment of the rotor and stator.

Abstract: 1451648 Automatic temperature control FUJI XEROX CO Ltd 27 Dec 1973 [29 Dec 1972] 59874/73 Heading G3R [Also in Division H2] In a circuit for controlling the conduction angle of a thyratron-type element arranged to be fed from a A.C. supply, and so as to pass an average current which is substantially independent of the A.C. voltage or frequency, a voltage a, proportional to the A.C. voltage is added to a voltage c proportional to a measured parameter and fed to one electrode of a comparison device, e.g. a programmable uni-junction transistor PUT, where it is compared with a voltage e, proportional to the frequency of the A.C. which is fed to a second electrode of the comparison device, a pulse being derived from the comparison device when the voltages on its two electrodes are equal. The Specification refers to temperature control of a heat fixing station of an electro-photographic copier by controlling the conduction angle of a thyratrontype element (not shown). The voltage a is obtained by full-wave rectification of the A.C. supply N by means not shown, voltage c is inversely proportional to temperature whilst the voltage e proportional to frequency of the A.C. supply N is obtained by integrating at R4, C4 (or by a LC integrator), rectification at D2 and smoothing at C2, C3, R3. The PUT is triggered when the sum of the instantaneous voltage at a with the control voltage at c becomes equal to the voltage e so that capacitor C1 is discharged via a transformer in the cathode circuit of the PUT, the resulting pulse triggering the thyratron (not shown) which controls the supply to the heater. C1 is discharged at the end of each half cycle by a pulse b. It is shown that the triggering time of the PUT is adjusted to compensate for variations in frequency and amplitude of the A.C. supply N, e.g. for operation on 50 or 60Hz supplies.
