Title: Fluid-controlling valves
IPC: F16K3/28
Filed: 1937-08-20
Abstract: 502,795. Valves. SAUNDERS, P. K. Aug. 20, 1937, No. 22844. [Class 135] A valve with straightthrough, substantially full-flow, bore has a wall of the bore substantially flat or continuously aligned, and a resilient plug 18 of uniform cross-section slightly smaller than and axially movable through a port 17 on the opposite side of the bore, the plug in closing position being expanded laterally to seal both the bore and the port 17. 'The plug is preferably of semi-hard rubber, of a hardness comparable with that of a soft wood such as deal. A gland 31 held by the cover 29 seals the casing when the valve is open. The cylindrical parts 14 of the bore, of a diameter (say) B, have rectangular ports 16 of height B and width ¥ B; and the horizontal diameter of that part of the bore in alignment with the chamber equals “ B. The plug is thus prevented from being blown through by a high pressure, when partly open. The plug and actuating mechanism are carried by the detachable cover 29 which can be secured in different angular positions by equidistant bolts 30. When used with high pressures, a balancing pressure (e.g. compressed air) may be applied above the plug to prevent it sticking in the gland 31, a second gland being provided between the handwheel 28 and the cover 29. Or by omitting gland 31 the pressure of non-noxious material under-control may act on both ends of the plug. The plug may have a swivel instead of a hinge connection 25, the hand wheel 28 being fixed to the screw spindle instead of to the nut 27, and a flexible diaphragm may replace the gland 31. Specifications 27678/12, [Class 135], 362,953, and 437,463 are referred to.

Title: Process for the production of potassium perborate
IPC: C01B15/12
Filed: 1954-08-06
Abstract: Potassium perborate K2 (B2O6.2H2O2) is prepared by progressively adding a potassium metaborate solution to a hydrogen peroxide solution containing at least 20, preferably 30-40, per cent by volume of H2O2, the molar ratio of KBO2:H2O in the solutions being approximately 1:2. The metaborate solution, prepared e.g. from potassium hydroxide and boric acid is preferably introduced slowly, dropwise, into the hydrogen peroxide, with violent agitation, the main quantity of perborate thus being formed in the presence of an excess (in general a ratio of KBO2:H2O2 of at least 1:2.5) of hydrogen peroxide and residuel amounts being formed and crystallizing out by allowing the mixture to stand e.g. for 15 hours.  Thereafter the mixture may be cooled to O DEG C. or below, and when the concentration of active oxygen drops to below 1 g./100 ml., separated easily, without washing, e.g. with a centrifuge, dried e.g. in a vacuum chamber at 40-50 DEG C. and crushed to a powder.  Preferred conditions include the use of reaction temperatures not higher than 40 DEG C., preferably not higher than 30 DEG C., but higher than 5 DEG C., preferably higher than 10 DEG C.; of a pH not exceeding 9 throughout the reaction, e.g. due to the pressure of an excess of 1-4 mol per cent of boric acid.  A stabilizer such as magnesium silicate or a phosphate (e.g. sodium pyrophosphate may be added to the reaction components or to the solid product. Details are given of the X-ray diffraction pattern of the perborate, which includes characteristic lines at d = 2.65, 2.96 and 4.02\fa, where d is the distance between planes of atoms in the crystal structure.

Title: Information recording systems
IPC: G11C11/06
Filed: 1961-06-27
Abstract: 957,074. Magnetic storage circuits. STANDARD TELEPHONES & CABLES Ltd. June 27, 1961 [June 27, 1960], No. 23250/61. Heading H3B. [Also in Division G4] One core in a magnetic storage matrix is read out at the same time as a binary digit is written in a second core. As shown in Fig. 4, the matrix comprises two sections MI, MP, and each row wire L1-LP is reversed in direction through section MP so that a positive half-write row pulse in MI becomes a negative half-read pulse in MP. Both row and column drivers DL, DC1 are controlled by counters, and the sequential drive outputs are arranged to be applied alternately to the column wires C1- Cn1 and C2-Cn of the two matrix sections. Both driver units generate alternate positive and negative pulses. The row driver unit DL applies these pulses to a selected row until such time as all the row cores have been processed, while the column driver unit DC1 applies a positive pulse to one column wire, e.g. C1, at the same time as a negative pulse is applied to the next column wire in the sequence, e.g. C2. Thus a positive pulse in row L1 is a half write pulse in section MI and a half read pulse in section MP. If at the same time C1 is positively pulsed and C2 is negatively pulsed, then a binary " one " is written into the core at the intersection of L1 and C1 in section MI and the core at the intersection of L1 and C2 in section MP is read out. If a binary zero is to be registered at this time in MI, an inhibit wire INI extending throughout the matrix section is negatively energized by opening gate P6. In the next phase of operation the row driver DL applies a negative pulse to L1, and the column driver DC 1 applies a positive pulse to C2 and a negative pulse to C3. A core in section MI is then read, and writing of a binary digit takes place in section MP under the control of an inhibit circuit comprising wire INP and gate P5. The outputs induced by an interrogated core in a sense lead SOI or SOP are passed to a terminal SO by opening a gate P3 or P4 at the appropriate time. The row driver is shown in Fig. 7 and comprise magnetic cores each having opposed switching windings Eb, ta and a row output winding S. A core is selected and switched in a sense to produce a negative output by closing a switch G1-Gm, a switch Ga1-Gaq and opening a gate P8. The following positive pulse is obtained by closing the corresponding switch Gb1-Gbq and opening a gate 7. Fig. 5 shows the column driver in which the two opposed switching windings on two adjacent cores are energized when a switch S1-Sx and a switch SL1-SLB are closed and a gate P7 is opened. By closing, for example, switches S1 and S2 in turn, then core T 1 <SP>1</SP> produces a positive pulse. followed by a negative pulse from T 1 <SP>1</SP> in coincidence with a positive pulse from T 1 <SP>2</SP>. All the switches may be electronic and form part of counter units.
