Title: Improvements in or relating to digital registers
Inventor: PARKER BERNHARD DOLLMAN
IPC: H03K3/037
Filed: 1962-09-13
Abstract: 981, 296. Staticisers and dynamicisers. DECCA Ltd. Sept. 4, 1963 [Sept. 13, 1962], No. 35025/62, Heading G4C. A data storage register comprises a number of binary stages each having two bi-stable units, one of the four configurations of each stage being prohibited, one representing "nothing stored", and the other two "binary 0" and "binary 1". As shown each bi-stable unit comprises two NOR gates (which give a negative output only when all inputs are positive) such as 11, 12 coupled output-to-input and also cross coupled to another unit (13, 14) by the outputs and inputs of 12, 14. Thus when other inputs to the gates are positive each pair of gates forms a bi-stable unit, the configuration with 12 and 14 both giving a negative output being excluded. The potential on line 19 is derived from the earlier stage, so that with 12 and 14 of this earlier stage positive, representing "nothing stored" all following stages to the right will have the same configuration. A data bit in the form of a negative pulse a line 22 or 24 may now be entered into the left-hand stage; this switches one bi-stable unit to register 0 or 1 and removes the negative potential on line 19 of the next stage so that it can be set by a subsequent pulse on 23 or 25 (alternate stages are connected to each pair of lines). Further NOR gates 34, 35 allow serial readout, each pair being enabled only when the preceding stage has been emptied, and negative readout pulses being supplied on lines 42, 43 alternately and lines 26, 27 and 31, 32 provide for parallel read-in and read-out.

Title: Improvements in or relating to hydrants
Inventor: STUBINGTON RICHARD EDWIN
IPC: E03B9/02
Filed: 1960-10-17
Abstract: 917,904. Hydrants. MERRYWEATHER & SONS Ltd. Oct. 4, 1961 [Oct. 17, 1960], No. 35533/60. Class 69 (1). A hydrant valve has an hydraulic actuating device interposed between the hydrant valve member 5 and a valve-operating member 1 is so controlled by the pressure in the outlet side of the valve that it allows the valve to open when the outlet pressure is relatively low, but exerts a thrust tending to shut the valve which increases as the outlet pressure increases and thereby emits the outlet pressure. In the cylindrical skirt of the valve member 5 a piston 8 of the actuating device can move freely subject on its upper side to pressure from contact with the valve operating stem 1 and on its underside to hydraulic pressure conveyed by way of a channel 16 and a flexible pipe 9 from a cylinder 12 in the valve wall 3. When the stem is unscrewed to open the valve, the valve 5 will normally be lifted off its seating by water pressure as in Fig. 2. The hydraulic pressure in cylinder 12 is controlled by a piston 14 whose head 11 is subject to the water pressure in the outlet chamber 24 so that if the latter pressure is excessive the valve 5 is pushed down on to its seat 6, even if the operating stem 1 was previously withdrawn to an open position as in Fig. 2. A relief valve 19 can open if the pressure does not decrease when the valve is back on its seating. When the stem 1 is screwed down, as in Fig. 1, a projection 21 on the relief valve contacts the bottom of the stem and opens the valve 19 to admit water from the pressure inlet 22 into the cylinder 12 which returns the piston 14 to its normal position. Specification 854,004 is referred to.

Title: Improvements in measuring and gauging devices
Inventor: O'BRIEN RORY MORGAN
IPC: G01B7/00
Filed: 1957-11-21
Abstract: 887,564. Electric measuring systems. WATTON ENGINEERING CO. Ltd. Nov. 18, 1958 [Nov. 21, 1957], No. 36292/57. Class 40 (1). Portable apparatus for measuring a linear dimension on a workpiece by comparison with a slip gauge utilizes a balanced coil transducer with an armature movable by the workpiece when being measured. As shown (Fig. 1), a holder 5 is provided with a fixed arm 6 and a slidable carriage 8 having opposing knife edges 12, 14 and 11 respectively, between which a slip gauge 10 is located, the carriage 8 being held by a spring-loaded bracket 53 so that all the knife edges 11, 12, 14 touch the gauge 10. An extension of the carriage 8 carries a feeler arm 9 whose lower end, located inside the carriage 8, constitutes a metal armature 27 (Fig. 5) for a balanced coil arrangement 35, 36, 37, wound on an iron dust core. The workpiece to be gauged is placed between an upper knife edge 13 on arm 9 and knife edges 12, 14 on fixed arm 6, producing movement of the arm 9 by closing a slot 21 between the arm 9 and carriage 8. The corresponding displacement of the armature 27 at the lower end of arm 9 produces an unbalance current from coils 35, 37 which is indicated on a meter. Zero adjustment is effected by screws 22, 23 (Fig. 3), made of conductive or magnetic material, which are adjustably positioned in the field of coils 35, 36, 37. Screw 23 is uncalibrated for initial adjustment with screw 22 set at zero, the latter being used to offset electrically outsize workpieces by known amounts. Calibrated screw 22 may alternatively be used to bring the unbalance current back to zero, the measured rotation of the screw giving the error in the test-piece dimension. A horizontal bar 7, used when gauging round parts, has a sloping underface resting on a shoulder on the carriage 8 to ensure that the bar 7 is at the correct height for gauging the diameter of the workpiece. In a modification (Fig. 2), the holder 5 has a V- shaped support surface 56, and the sliding member 81 is clamped by a nut 85. The feeler 9 is flexibly attached to the member 81 by a cross-spring pivot comprising two axial, thin, blade portions 83 (Fig. 3), and the transverse slots below a sleeve 84, whereby displacement of the feeler 9 produces corresponding displacement of the armature 27 relative to the coil system 35, 36, 37. Adjustment of the unbalance current to zero for initial setting-up and for measurement of the displacement of the armature can alternatively be made on a similar transducer unit connected in parallel with the built-in transducer. Specification 887,565 is referred to.

Classes 37 and 41. A method of etching a surface of a silicon carbide single crystal comprises the steps of applying to the said surface an electrolyte comprising a water-miscible non-oxidizing liquid and an aqueous solution having dissolved therein from 1 to 10% by weight of a compound which under the influence of an electrical current will ionize to provide ions capable of oxidizing silicon carbide, said non-oxidizing liquid being present in said electrolyte in an amount sufficient to impart a predetermined electrical conductivity upon said electrolyte, the amount of said non-oxidizing liquid being up to 30 times the amount of said aqueous solution, and applying an electrical current to said surface and said electrolyte so as to render said surface anodic at a potential of not in excess of 25 volts and a current density of from 0.0625 to 6.25 milliamperes per square millimetre of said surface. The crystal may be at least partially immersed in the electrolyte, the electrical current being applied with the assistance of at least one electrode in contact with the electrolyte, or the electrolyte may be separated by an electrically insulating partition member having an aperture therein into two bodies, each containing an inert electrode, the crystal then being mounted over the aperture so that the said surface is rendered anodic. The silicon carbide single crystal may comprise two members of opposite conductivity types having a PN junction therebetween, in which case a voltage is applied to the two members across the said junction and the electrolyte is applied simultaneously at least to portions of the surfaces of both of said members and to the junction. Suitable electrolytes which may be used include hydrogen fluoride, hydrogen chloride, per-chloric acid, sodium fluoride, ammonium chloride, potassium acid fluoride, sodium acid fluoride, alkali metal hydroxides or alkali metal carbonates. Mixtures may be used to ensure that the silicon oxide which is produced by the etching process is dissolved and thereby removed from the surface being treated. The non-ionizing liquid may be methanol or ethanol or another non-ionic liquid such as a hydrocarbon or ether. The container in which the process is carried out may, when the electrolyte is hydrogen fluoride, be made of a suitable plastic such as polyethylene, or when other electrolytes are being used may be made of glass or ceramic. The inert electrodes may be of platinum or carbon.
