Title: Interpolation device
IPC: H03M1/00
Filed: 1964-10-29
Abstract: 1,091,596. Cathode-ray tubes. CARL-ZEISS-STIFTUNG, [trading as CARL ZEISS]. Oct. 29, 1964 [Oct. 30, 1963], No. 44101/64. Heading H1D. [Also in Divisions G1 and G4] The movement of a scale 15 (Fig. 6) is scanned by a transmitter 16 which emits sine-shaped signals phase-displaced by 90 degrees to the deflecting plates 18, 19, 20 of a cathode-ray tube 21 and, as the electron beam scans the screen of the tube, signals are emitted from conducting sections of the screen. In one embodiment the screen comprises equal segments of conducting and non- conducting portions 26, 27, the signals being passed via a photoelectric cell to a pulse generator and counter. In another embodiment (Fig. 8) two superimposed screen discs 35, 36 with partially overlapping screen elements 37, 38, respectively, are constructed so that 50% of the impinging electron beam passes through the element 37, the underlying portion 38<SP>1</SP> allowing the full 50% to pass and a voltage pulse is consequently emitted as the beam moves from A to B. The portion 38<SP>11</SP> not covered by the screen element 37 has a screening capacity of 50% and as the screen element 38 is scanned from C to D a correspondingly phase-deflected voltage impulse is emitted. With this embodiment the direction of movement of the scale may be determined. In a further embodiment (Fig. 9) the appropriate number of an indicating tube 43 is lit when the electron beam strikes one of the elements 40. Similarly one of the numbers of the tube 45 is lit when the electrons impinge on one of the subdivisions 44 of the elements 40. In a further embodiment (Fig. 10) voltages taken from resistances connected to concentrically arranged grid screens 50, 51 in which the screening capacity varies according to the angle of the beam, and applied to the deflecting plates of a second cathode-ray tube so that the electron beam of the second tube moves ten times more quickly across a screen arrangement as shown in Fig. 9, the elements 40 then representing <SP>1</SP>/ 100  units and the elements 44 <SP>1</SP>/ 1000  units. The <SP>1</SP>/ 10  units may be received from a further screen.

Title: Steam power plants with intermediate reheating
IPC: F01K7/44
Filed: 1960-12-22
Abstract: 891,136. Steam turbine plant. SULZER FRERES S.A. Dec. 22, 1960 [Dec. 23, 1959], No. 44119/60. Class 110 (3). A steam turbine plant comprising an intermediate reheater between two stages and at least one secondary consumer has at least one tapped steam supply line to the secondary consumer from a main turbine of the plant and another tapped steam supply line to the secondary consumer from the intermediate reheater. Steam from a boiler 1 is led to a highpressure turbine cylinder 3 which discharges through an intermediate reheater 5 to the lowpressure turbine cylinder 6. From an intermediate header 7 steam passes through a line 10 containing a regulating valve 11 to an auxiliary turbine 8 driving a generator 9. A by-pass 12 fitted with a restrictor 13 is connected in parallel with the valve 11. A steam line 14 tapped from the low-pressure turbine 6 and fitted with non-return valves 15, 16 also leads to the auxiliary turbine 8. A preheater 18 is connected as another secondary consumer to a branch 17. A pressure measuring element 19 measures the steam flow into the auxiliary turbine 8. At normal load, steam for the auxiliary turbine 8 is taken from the lowpressure turbine 6. As the load on the main turbine decreases the steam pressure in the line 14 drops and the measuring element 19 adjusts the valve 11 so that steam flows from the intermediate superheater into the auxiliary turbine 8. The restriction 13 allows sufficient steam to flow through line 10 even when valve 11 is closed so as to prevent condensation when the valve 11 is opened. In a modification, an additional regulating valve is located in the line 14. In this arrangement a speed governor on the auxiliary turbine shaft first opens the additional regulating valve and when this valve is completely open, the valve 11 is opened and the additional regulating valve closed, if no non- return valve is provided in the line 14. In another modification, Fig. 4 (not shown), the auxiliary turbine drives a boiler feed pump and the regulating valves in the supply lines from a main turbine cylinder and the reheater are controlled by a speed governor driven by the auxiliary turbine. In a modification of this arrangement, Fig. 5 (not shown), a desired value signal from the feed water regulating system or load regulator is led to a regulator where it is compared with the actual speed of the auxiliary turbine. The regulator then transmits to a comparator unit a control signal corresponding to the desired value of the pressure of the steam supplied to the auxiliary turbine where it compared with the actual steam pressure and a regulating signal transmitted to one or other of the regulating valves in the bled steam supply lines.

Title: Process for the electrolysis of alkali metal chloride solutions
Inventor: SCHUCKER JOSEF
IPC: C25B1/36
Filed: 1962-11-26
Abstract: A process for the electrolysis of alkali metal chloride (e.g NaCl) solutions in cells having adjustable anodes and a liquid cathode (e.g. of Hg) comprises immersing the anodes during operation in the liquid cathode and applying current densities of at least 7000 amps./m.2 of the cathode surface (e.g. 7000-20,000 amps./m.2). Increased current efficiency is thereby achieved.  Short circuit between the electrodes when the anodes are immersed in the liquid cathode is prevented by an emulsion film formed by the brine electrolyte together with very small bubbles of Cl2 generated at the anode.  Fresh brine is drawn into the electrode gap as the emulsion rises.  The process can be applied to horizontal electrolysis cells and those with a vertical or inclined cathode, i.e. with the cathode formed by Hg flowing down through slots of a distributing device or over an inclined cell bottom.

Abstract: 1,187,589. Teleprinters. MARCONI CO. Ltd. 17 Aug., 1967 [6 Oct., 1966], No. 44777/66. Heading B6F. In a teleprinter wherein characters on a continuously-rotating wheel 1 are struck by a hammer 6 the operation of which is synchronized by signals from a signal generator 8, 9 the rotating part 9 of which is driven by the same motor 4 that drives the wheel 1, means responsive to variations in the rotational speed of wheel 1 are provided to vary the times of firing of the hammer to compensate for incorrect timing of the hammer firing due to such variations of speed. As shown, the signal generator comprises a phonic wheel 9 driven from the shaft 3 of the wheel 1, and a pick-up 8, the latter applying synchronizing signals to a hammer-firing control circuit 7. The drive to the wheel 9 comprises a member 14 fixed to the shaft 3 and having two weights 11, 12 pivoted thereto at opposite ends 13 and urged together at the ends by springs 18. Pins 15 on the weights engage slots 16 in the wheel 9. At normal speed of rotation, the wheel 9 is in an intermediate position in its range of permissible movement relative to member 14 and wheel 1 but if the motor speed varies, the centrifugal action of the weights causes the wheel 9 to be retarded or advanced to provide the timing compensation referred to. The centrifugal device may be employed to advance or retard the pick-up 8 instead of the wheel 9.

Title: Semiconductor memories
IPC: H03K3/286
Filed: 1971-09-27
Abstract: 1365727 Semi-conductor data store HITACHI Ltd 27 Sept 1971 [25 Sept 1970] 44956/71 Heading G4C [Also in Division H3] Each cell M11, M12 &e. of a memory matrix has cross coupled transistors Q 01 , Q 11  with respective collector loads which switch from a high to a low impedance when the cell is selected by a positive address voltage AD1. When AD1 goes positive a multi-emitter T3 turns on and connects relatively low value resistors (R c2 , Fig. 11, not shown) across relatively high value resistors (R c1 ). Alternative ways of switching from high to low resistance are: a similar multiemitter arrangement (Fig. 10, not shown) but having the high resistors connected also to the address voltage line AD instead of to earth; a diode in series with each low resistor, the combination being connected across the high resistor or across a series-parallel arrangement of the high resistors and a common, anti-saturation resistor connected to the address line (B c0 , Fig. 9, not shown); a plurality of diodes (Fig. 13, not shown) or transistors (Fig. 14, not shown) connected between intermediate points on the  high and low resistors; and a diode (Fig. 12, not  shown) connected across the high resistor which  is in series with the low resistor. An antisaturation resistor (R c3 ) may be connected between the collectors, or alternatively a parallel pair of oppositely poled Schottky diodes (Fig. 7, not shown). In the matrix Fig. 15, X selection is by raising AD1 &c. potential; and Y selection by turning on T30, T31 or T32, T33, &c. to lower the digit line pairs DL1, DL2, this also causing the diodes D30, D31 &c. to turn off, which usually conduct the holding current for the unselected cells to a source J1, J2. If the whole matrix is unselected, the hold current is carried by RS1, RS2 &c. and neither the "select" current sources J 00 , J 01  nor the "unselected" current sources J 1 , J 2  are operative. To read, an amplifier T37, T38 responds to a differential output from the selected cell, non-selected cells in the same row having no effect, due to the corresponding emitters of T37, T38 being reverse biased by V CL  through T39 and the corresponding pairs of diodes D32, D33 &c. To write, T35 and T36 respond to 0 or 1 signals to appropriately raise one of the digit lines to the selected cell.
