Abstract: 1,020,689. Reservoir toothbrushes. L. W. SANDERSON. Jan. 11, 1965 [Oct. 11, 1963], No. 40219/63. Heading A4K. In a reservoir toothbrush, in which a continuous flow of liquid is supplied to the bristles 1, through duct 8, under the action of compression spring 5 on piston 4, the flow is terminated, on 'replacing end cap 9, by means relieving the liquid of the pressure of spring 5. To effect this, rod 10 extending axially from the cap 9, is thrust into the interior of stem 2 and engages the end of rod 6 thus driving piston 4 back to the fuly compressed position (Fig. 1) of spring 5. In this position, disc 12 may be removed, to refill cylinder 3 through ducts 11 and 13. On removal of cap 9, spring 5 propels piston 4 and rod 6 forwardly to seal ducts 13, while providing the continuous flow through duct 8. The bristles 1 can be arranged cylindrically on stem 2 or, alternatively, may be provided on only one side of the stem.

Abstract: 970,192. Metal vapour lamps. DEUTSCHE AKADEMIE DER WISSENSCHAFTEN ZU BERLIN. Aug. 20, 1962, No. 41230/60. Heading H1D. A gas - discharge lamp, particularly for flash operation, comprises a mercury cathode and an inert gas filling at a partial pressure which is greater than 100 Torr in the cold state of the lamp, whereby the mercury-vapour partial pressure is so low compared to that of the inert gas, that during operation the ionization of the inert gas predominates over that of the mercury vapour. As shown, the crosssection of the envelope 4 is reduced at the meniscus of the cathode in order to stabilize the cathodic focal spot. The anode 3 may be of tungsten, molybdenum or low-carbon iron, or of mercury if the lamp is of suitable shape. Non- conductive deposit, such as mercury-anode material compounds, which accumulate on the envelope during use may be periodically removed from the region adjacent the discharge path by external heating so that these deposits are transferred to the anode cavity. Preferably, the cathode mercury, with a drying agent, is distilled several times in a vacuum before being inserted into the lamp.

IPC: G05B19/33
Filed: 1959-12-04
Abstract: 882,145. Electric copying-machines. SIEMENS-SCHUCKERTWERKE A.G. Dec. 4, 1959 [Dec. 6, 1958], No. 41375/59. Class 38 (6). [Also in Group XXII] To avoid inaccuracies due to wear, the movable carriage of a machine tool is positioned by a driving lead screw in accordance with the positioning of a measuring head on a measuring lead screw. The carriage 1 is positioned by a lead screw 3 driven by an electric motor 4 through a differential gear 15. The motor 4 also drives the measuring lead screw 5 through gears 18, 19 the ratio of which corresponds with the ratio of the pitches of the two lead screws. A measuring head 10 is movable by the measuring lead screw and the position of the head 10 is measured by an unspecified device 7 in accordance with the angular movement of the screw 5. The output of the device 7 is compared with a command signal at 8 (said to be obtained from a punched card) to provide an error signal for the motor 4 to drive the head 10 to a position corresponding to the command. An unspecified device 11 detects any positional error between the head 10 and the carriage 1 to provide a signal, amplified at 13, to control an auxiliary motor 16 which rotates the cage of the differential 15 through a worm gear 17.

Abstract: 1369001 A/D converters and digital conversions SOC ITALIANA TELECOMMUNICAZIONI SIEMENS SpA 8 Sept 1971 [18 Nov 1970] 41870/71 Heading G4H In an A/D converter, the input is compared with different thresholds in parallel, and successive groups of the comparators feed respective groups of gates, a group of gates being disabled by the lowest-threshold comparator of the next higher group unless the input is below this lowest threshold level. An analogue voltage level is compared in 256 differential amplifiers with respective threshold levels, the amplifier outputs being gated to respective bi-stables. The 256 levels are categorized into 16 ranges of 16 levels each. The output from the bi-stable corresponding to the lowest threshold in each range is called a "reaction" signal and the outputs of the other 15 bi-stables are called "level" signals. Each "reaction" signal (other than that in the lowest range), if it is equal to one, inhibits the "level" signals of the next lower range. The "level" signals are supplied to circuitry in which correspondingly positioned signals in the different ranges are ORed together giving a 15-bit output which is then coded into 4-bit pure binary form and gated into bi-stables to represent the position of the analogue input level within the range it occupies. The "reaction" signals (other than that in the lowest range) are also coded into 4-bit pure binary form and gated into bi-stables to represent the range occupied by the analogue input. The two 4-bit binary numbers are then serialized.

Abstract: 1362001 Control of brushless motors NAUCHNO-ISSLEDOVATELSKY PROEKTNO-KONSTRUKTORSKY I TEKHNOLOGICHESKY INSTITUT ELEKTROMEKHANIKI 9 Sept 1971 42016/71 Headings H2A and H2J A brushless D.C. motor has windings 1 energized from a D.C. supply through a switch 2 comprising transistors 11 ... 16 and a rotor 6 coupled to an inductance type position sensor 5 whose digitally-coded outputs at a, b, c control the transistors 27, 28, 29 of a circuit 3 having further transistors 30, 31, 32 which, together with transistors 27, 28, 29, control the transistors of the switch 2. The transistors 27, 28, 29 also control, via R.C. circuits 44, 47; 45, 48 and 46, 49 of a member 4, a bi-stable circuit 7 including transistors 53 54 which are also controlled by an oscillator 8, the two states of the circuit 7 corresponding to the on and off conditions of a semi-conductor switch 9 whose transistor 66 controls the application of a power supply 10 to the sensor 5. To start the motor, a signal from oscillator 8 changes the state of  the circuit 7 which closes the switch 9 to apply the supply 10 to the sensor 5, which then produces output signals at a, b, c to change the states of certain of the transistors 27, 28, 29, and hence the states of certain of the transistors 30, 31,32, the resultant effect being to switch on three of the transistors 11 ... 16 (all previously off) to produce appropriate current flows through the windings 1. Movement of the motor shaft causes one of the outputs of senser 5 to change from a positive to a zero value to switch on one of the transistors 27-29, which action applies a signal via the corresponding R.C. circuit of member 4 to change the state of the circuit 7 and so open the switch 9 to remove the supply 10 from the sensor 5. The absence of output signals at a, b, c allows the transistors 27 ... 32 and 11 ... 16 to revert to their original conditions corresponding to the de-energized state of the windings 1. A further signal from the oscillator 8 repeats the above action but with different transistors 11 . . . 16 of the switch 2 being turned on. The motor thus speeds up until the on-off rate of the supply to the sensor 5 is equal to the frequency of the oscillator 8. Thereafter the closing time of the switch 9 depends on the phase difference between the motor speed and the frequency of the oscillator, the phase difference being determined by this frequency, the voltage of the motor supply and the load on the motor. The switch 2 is thus controlled to pulse-width modulate the D.C. voltage applied to the windings 1, variation of the applied voltage being caused by variation of the load on the motor, with the speed remaining constant, or by variation of the frequency of the oscillator 8 to vary the speed of the motor.
