Title: Voltage indicator tube having two indicator systems
IPC: H01J31/14
Filed: 1961-04-14
Abstract: 978,223. Cathode-ray indicator tubes. STANDARD ELEKTRIK LORENZ A.G. April 14, 1961 [April 16, 1960], No. 13575/61. Heading H1D. A voltage indicator tube comprises two sets of electron beam generating and deflecting electrodes separated by a partition, and a common image display screen. Each set of electrodes produces a pair of electron beams whose angular separation is dependent on an applied signal voltage, the sets of electrodes being so disposed with respect to the screen and the partition that for signal voltages below a given value the electron beams adjacent the partition, one of one set and the other of the other set, are intercepted by the partition so as not to fall upon the display screen. As shown in Fig. 1, two systems, for indicating and comparing two voltages, each comprising cathode 3, deflection electrode 5, grid 4 and control electrode 10 and anode 11 of an amplifier section, are arranged on opposite sides of a partition 6 connected to or integral with support structure 2 and electrically connected to luminescent screen 8 by contact 12. A colour filter 9 is arranged opposite the centre of the elongated rectangular slot in shield 2 so that a colour change is obtained for indication voltages above a certain value. More than one colour change may be obtained by use of appropriate filters or by use of luminescent materials with different colour emission. A conductive layer 7 of tin oxide is provided under the luminescent layer 8. A clear indication of voltages above a certain value may also be obtained by use of a shield 2 having an aperture shaped as shown in Fig. 11. Alternatively, the two indication systems may be so arranged that the two electron beams nearest partition 6 fall on screen 8 for signal voltages above a certain value, Fig. 6 (not shown). In a further embodiment, two indication systems are arranged between sheet metal parts 15, 15a, 16 on opposite sides of partition 6. The luminescent screen is formed on a bowl-shaped sheet-metal anode 13 having a triangular notch 14. The relative dispositions of the sets of electrodes and the partition may be such that for signal voltages above a certain value, electrons from both sets of electrodes fall upon the same portion of the screen to produce a region of enhanced brilliance.

Abstract: 1,142,183. Data processing apparatus. BURROUGHS CORP. 23 March, 1967 [25 March, 1966], No. 13619/67. Heading G4A. In an instruction word format comprising an operation code portion and an address portion, this latter portion comprises bits defining a particular data word address and controller bits indicating the binary code of the data word stored at that address. Data words may be stored in memory according to any of a number of binary codes, in particular as unsigned 4- bit numeric digits, signed 4-bit digits or unsigned alphanumeric 8-bit characters. All processing of data is performed on signed alphanumeric 8-bit characters, the necessary conversion taking place in control circuitry provided between the memory and processor. Thus, 4-bit digits in memory have bits 0101 added on being read-out for processing and unsigned words have a + sign (1100) digit added. The controller bits are also used for controlling indirect addressing and indexing. The instruction word format (Fig. 1A, not shown) comprises a 2-digit operation code, two 2-digit operand length indicating codes and three 6-digit address portions each with a 1-digit controller bit section, the digits in all cases being of 4-bits. The memory may comprise core storage and a micro-programme control read-only store is provided.

Abstract: 1,030,973. Navigation systems: integrators. GENERAL PRECISION Inc. March 31, 1965 [May 11, 1964], No. 13701/65. Heading G4H. To obtain the longitude position of a vehicle or aircraft, a resolver 13, Fig. 1 (not shown), is positioned in accordance with the ground track angle GT and receives an A.C. voltage, the amplitude of which represents the ground speed Vg, from a potentiometer 11. The output KVg. sin wt. sin GT is applied to AND gates 16, 17 so that depending on the phase of the A.C. signal, positive or negative half-cycles are passed to an integrater 20. Further positive or negative half-cycles are supplied to integrator 20 from gates 16a, 17a in dependence on the latitude angle, this being to allow for the fact that, for a given Vg and GT, the rate of change of longitude varies with the latitude angle. Integrator 20 applies a level detector 22 which enables one or other of gates 24, 25 to pass clock pulses to the forward or backward input of a stepper motor 28 driving a counter 30 displaying the longitude position. Gates 16a, 17a are enabled by gates 32-37 in dependence on the condition of flipflop 26. The second output of resolver 13 is used in the latitude integration channel (not illustrated).

Abstract: 834,835. Trigger mechanisms STERLING ENGINEERING CO. Ltd. April 2, 1958 [April 30, 1957], No. 13729/57. Class 119 A trigger mechanism in which a change-fire device determines the operating position of a sear 5 capable of longitudinal movement in respect of a trigger 2, including disconnection therefrom due to an interposed spring 8, has a second spring 10 mounted independently of the trigger to assist the first spring in moving the sear consequent on release of the trigger. The sear 5 has an elongated hole 7 to house its pivot and a step 4 engaging a step 3 on the trigger. The spring 8 has a plunger 9 which contacts perpendicularly a flat on the trigger. The change-fire device can be rotated to any of three positions and retained there by a spring 16; an abutment 14 being brought opposite to a face 17, a recess 19, or a face 18 of the sear corresponding respectively to "safe", "semi-automatic" and "automatic". Depending on the position of the abutment 14 the sear is either locked with its tip 20 in a bent in the bolt; or the sear is unaffected by it, and is pushed back by the spring 8, to disengage the step 4 from the step 3 on the trigger; or the sear is held to retain the steps 3 and 4 continually in contact. The second spring is on a rod 11, pivoted to the sear at 12 and to the frame at 13. It reinforces the spring 8, which is inadequate alone to re-engage the tip 20 in the bent at "semi-automatic". To avoid transferring impact between the bolt and sear to the trigger at "automatic" the steps 3 and 4 are made to lie below a line 23 joining the pivots 6 and 22 of the trigger and sear.

Title: Improvements in or relating to self-locking brake shoe adjusting means
IPC: F16D65/54
Filed: 1938-05-10
Abstract: 514,571. Adjusting brake shoes. HOF,. H. VAN DER. May 10, 1938, No. 13976. [Class 103 (i)] In automatic brake-shoe adjusters comprising an inner part carrying an element which is adapted to permit said part to move freely in an outer tubular part in one direction but to prevent movement in the other direction, the tubular part is formed with a bore passing right through it to enable the inner part and/or the locking element to be passed through the outer part in the direction in which the element is selfreleasing for the purpose of resetting the adjuster. The adjuster in Fig. 8 comprises parts 2, 13 connected at 7, 22 respectively to a brake shoe and to a fixed part, the part 2 carrying a flexible disc 3 which acts as a uni-directional locking element for the part 2 relatively to a tubular part 1. The brake release springs normally urge a pin 20 to the other end of a slot 21 against the action of a spring 25. If when the brake is applied the shoe movement exceeds that corresponding to the clearance of this pin in the slot, the part 2 is withdrawn to an extent from the part 1. For resetting the adjuster, the part 13 can be detached and the part 2 be inserted in that end of the part 1 after having been wholly withdrawn through the other end or the element 3 can be detached after withdrawal of the part 2 and be re-inserted at the other end of the part 1 and re-attached to the part 2. The device may comprise only the parts 1, 2, 3, the hole through the part 1 being used for attachment to the shoe or fixed part and being elongated to determine the shoe clearances or the part 1 may have a screwed-on cap. In Fig. 6, the lost-motion between parts 1, 10 is provided by a slot 8 and a pin 26 by which also the part 10 is attached to the shoe or fixed part. The locking elements may comprise spring-urged plates 27, Fig. 6, or balls 15, Fig. 4 arranged to wedge between a conical part of member 2 and the part 1. The balls may be disengaged for resetting, by a slidable bush 14 or the parts 2, 14, 15 may be withdrawn from the part 1 and passed into its other end after removal of the plug 13. The part 1 may have an internal circumferential groove, in such a position as to prevent the locking element from being effective when the shoe lining has been substantially worn, thus warning the operator by the consequent increase in pedal travel. Specification 493,091 is referred to.

Filed: 1926-06-04
Abstract: 254,289. Ollier, C., and Ferry, E. Testot-. June 26, 1925, [Convention date]. Systems for supplying consuming devices from variable speed generators.-The electrical apparatus of a motor vehicle is provided with devices which prevent electrical damage to the apparatus in the event of short circuits or rupture of leads, and is also provided with auxiliary lights which can be brought into operation even though a short circuit or a rupture has occurred. The apparatus comprises the usual battery 2, distribution board 3, dynamo 1 and lead to main lights 4. An excess current limiter 8 comes into action if the lead 6 is short-circuited to the frame. It comprises a series coil 8<b> for pulling the armature away from a fixed contact 9 so as to break the circuit, and a shunt coil 8<c> which then comes into action to maintain the armature in its displaced position. A contactor 11 is provided to close on to contact 9 when its coil is excited by the dynamo voltage. Should a connection between the dynamo 1 and the battery 2 be ruptured, the dynamo is prevented from generating a voltage dangerous to the lights 4 by reason of a vibrator 13 which intermittently closes on to a contact 12 to earth the dynamo and de-energize its operating coil 13a. An auxiliary light 24 and another light 25, which is in series with a resistance 26 and which may serve as a rear light, are connected between the mid point of the battery and a three position switch 19. By moving the switch 19 on to either of the extreme contacts 22 or 23, the lights 24, 25 can be supplied from either half of the battery no matter what fault has occurred. The Specification as open to inspection under Sect. 91 (3) (a) comprises the use of the contactor 11 for completing the battery charging circuit in the event of the limiter 8 falling to close. It also included five other circuit diagrams. This subject-matter does not appear in the Specification as accepted.

Filed: 1939-05-12
Abstract: 529,103. Duplex wireless signalling; frequency and phase modulation. PERCIVAL, W. S. May 12, 1939, No. 14242. [Class 40 (v)] In combined wireless transmitter and receiver apparatus for two-way operation employing frequency or phase modulation, the transmitter oscillator is employed as a local oscillator for the adjacent receiver. As shown in Fig. 1, a common aerial is employed for the transmitter 1 and the receiver 2. The transmitter may generate a 250 m.c. wave which is fed to the aerial through a filter circuit designed to present low impedance to the transmitted wave but high impedance to the 245 m.c. received waves. The aerial is connected to the receiver 2 through another filter circuit which readily passes the received wave, but allows only a suitable fraction of the transmitter energy to reach the receiver and set up therein a 5 m.c. intermediate frequency. The distant station has a similar circuit arrangement, but the transmitter is tuned to 245 m.c. and the receiver to 250 m.c. Separate aerials may be associated with each transmitter and receiver, the local oscillation for the receiver being radiated from the adjacent transmitter. Depth of modulation in a transmitter may be indicated in the adjacent receiver; or if desired the signals from the adjacent transmitter may be balanced out in the detected output of the receiver. Both transmitters may be provided with suitable means for stabilizing their frequencies; or one transmitter only may be directly stabilized, the other being adjusted by means responsive to changes in the intermediate frequency in the adjacent receiver. In a third arrangement neither frequency is directly stabilized, but AFC means are provided for maintaining a constant difference between them. Specification 170,154, [Class 40 (v)], is referred to.

Abstract: 347,022. Measuring speed of a ship acoustically. CHILOWSKY, C., 15, Rue du Lunain, Paris. May 9, 1930, No. 14345. Convention date, May 11, 1929. [Class 106 (iii).] Acoustic speed indicators.-The speed of a vessel is measured by observing the Doppler effect when beams of ultra-audible waves directed obliquely towards the bottom of the sea are reflected therefrom, the frequency of the echo waves being measured by a piezo-electric wave-meter which may be graduated for direct reading. A great number of resonators having distinct frequencies are used. In the preferred form these consist of quartz or other piezo-electric crystals. These are mounted in an alternating current field affected by the reflected waves. Different resonators will be affected according to the speed of the vessel and as each is arranged in the path of a beam of polarized light which is regulated to extinguish light by means of compensators and an analyser, when one is resonated a spot of light is allowed to emerge. In one form these quartz plates are arranged in a circle and surrounded by a fixed scale adjacent which the spot of light may be read, and the speed indicated. To compensate for pitching and rolling of the vessel, the scale is moved about the centre of the circle of quartz plates by a gyroscope. In a second form a large number of plates are disposed between two coatings in a tube containing rarefied gas in which is an electrical field under which circumstances a luminous spot is produced when a crystal vibrates. Specification 227,788, [Class 118 (ii), Signals], is referred to.
