IPC: B65D83/04
Filed: 1968-07-26
Abstract: 1281517 Tablet dispensers WELLCOME FOUNDATION Ltd 22 Oct 1969 [26 July 1968] 35834/68 Heading B8P A tablet dispenser having a wheel with at least one pocket to accommodate a tablet has one face of each pocket co-planar with the tops or bottom face of the dispenser, the depth of the dispenser being substantially greater than the depth of the pocket. This construction enables a larger number of tablets to be held in the dispenser since they do not need to be arranged in a single plane. The wheel 32 has pockets 35, is mounted on a strip shaft 16, and has a milled periphery. Each tablet is dispensed through a gap 28 in the dispenser. An arcuate member 17 separates the tablets from the lower part of the wheel and an arcuate skirt 29 prevents other tablets jamming the wheel as it is rotated. The dispenser can be moulded from a plastics material.

Title: Improvements in and relating to electrical superconductive switching components
IPC: H03K3/38
Filed: 1957-11-19
Abstract: 870,144. Superconductive circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 19, 1957 [Nov. 19, 1956], No. 3596/57. Class 40 (9). The resistance of a superconductive wire is varied incrementally. A superconductive wire 11, Fig. 2, mounted on a flat support 12 is arranged with strands parallel to the axis of a magnetizing coil 10. As the current in the coil 10 increases, the boundary of the effective field (which is equal to or greater than the critical field) advances towards the axis of the coil and the resistance of the wire 11 increases incrementally as successive strands are enveloped by the effective field. In an alternative arrangement, Fig. 3, strands 15 of different superconductive materials are mounted on the internal surface of the former 17 on which the magnetizing coil 16 is wound. Each strand material changes to normal conductivity at a different critical field strength. Tri-stable circuit. Fig. 5.-One unit of current in coil 20 (or 21) is sufficient to make one wire b (or a<SP>1</SP>) normal and two units of current make both wires b, a (or b<SP>1</SP>, a<SP>1</SP>) normal. The coils 20, 21 are of material with a high critical field so that they are not driven normal by any of the currents used. The circuit is stable with two units of current in coil 21. Wires b<SP>1</SP>, a<SP>1</SP> are then normal. Coil 20 and normal wires b<SP>1</SP>, a<SP>1</SP> are shunted by superconductive wires a, b and coil 31. In a second stable condition, two units of current flow in coil 20 and none in coil 21. In a third stable condition one unit of current flows in each coil, strands a, b<SP>1</SP> being superconductive and strands b, a<SP>1</SP> being normal. The circuit is set to the condition in which coil 21 conducts by opening switch 45. With switch 45 closed, the circuit can be stepped into the second and third stable conditions by discharging condenser 47 through coil 20. Each discharge momentarily adds one unit to the current flowing in coil 21. The current in coil 21, which may be one, two or three units flows through coil 30 and controls the resistance of a wire 31 arranged in the manner illustrated in Fig. 2. The voltage across terminals 34, 35 may be indicated by a voltmeter. A circuit provided with further wire strands c, c<SP>1</SP> &c. (not shown) may have four or more stable states.

Title: Beam current limiting circuit for a cathode-ray tube
IPC: H04N9/64
Filed: 1975-09-05
Abstract: 1514220 Cathode ray tube circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 Sept 1975 [9 Sept 1974] 36619/75 Heading H4T The beam current in a cathode ray tube is limited by a control signal generated by a circuit responsive to the cathode current, the circuit being so connected to the cathode that its input has substantially no effect on the current. The connection may, for example, be an amplifier or a high value resistor. The control signal generating circuit includes a time constant circuit. In one embodiment. Fig. 1, the cathode of a colour television C.R.T. 25 is connected to a voltage Vk via a low resistance 27. The voltage across the resistor is proportional to the beam current and is applied to amplifying transistor 37. Diode 31 clamps the minimum value of the voltage applied to the amplifier to a chosen value, e.g. 0À7v. The amplifier feeds a time constant circuit 43, 45 which applies a voltage proportional to the mean of the beam current to thresholding transistor 49 whose output is applied to capacitor 57. The capacitor also receives a voltage from a thresholding transistor 59 which depends upon peak values of the beam current. The capacitor voltage is therefore dependent on both the mean and peak beam current and is used to control luminance and chrominance amplifiers 9, 15 which feed colour matrix 11 and demodulator 19, so as to control the contrast and saturation and limit the beam current. In addition a black level control signal may be derived by measuring the black level beam current appearing across a diode (not shown) connected between cathode resistor 27 and Vk. In a second embodiment, Fig. 2 (not shown), resistor 27, Fig. 1, is placed in series with a diode (63), the serial combination being shunted by a high resistance (65). During high beam current the diode conducts so that the cathode voltage is limited. Resistor 27 is connected to the beam current control circuit as in Fig. 1. In addition, the voltage at the cathodes is passed via an amplifier (67) to a circuit (71) which measures the black level beam current at the three cathodes during three line periods of the field blanking interval and generates control signals which are applied to amplifiers (79, 81, 83) connected to the outputs of the matrix 13. In a third embodiment, Fig. 3, the cathodes are connected to respective resistors and diodes as shown. Thresholding transistor 97 causes a capacitor 103 to develop a voltage dependent on the peak currents in the cathodes. A voltage dependent on the mean of the cathode currents is developed on capacitor 111, this voltage being combined at 113 with the peak-dependent voltage to provide a beam control signal to amplifiers 9, 15. The transistor 109 provides a signal to an amplifier 67 feeding a black level measuring circuit as described with reference to Fig. 2.
