Title: Electrical indicators
IPC: G01R5/16
Filed: 1966-12-08
Abstract: 1,120,379. Electric meters. GENERAL MOTORS CORP. Dec. 8, 1966 [Dec. 17, 1965], No. 54917/66. Heading G1Q. The field coils 12, 18, 22 of a centre-zero moving magnet electric meter are so arranged that the total range of armature travel is substantially greater than 180 degrees. The armature 26 is a diametrically magnetized disc biased toward the zero position by a fixed magnet 28. The coils are connected as shown so that for a D.C. or rectified A.C. signal from source 10, the coil 12 will always be energized but only one of the coils 18, 22 can be energized, and then only if the input voltage exceeds the forward voltage drop of the respective diode 20 or 24. The coils are physically disposed in the relative directions shown so that the field produced by coil 12 is perpendicular to, and that by coil 18 or 22 parallel to, the bias field produced by the fixed magnet 28. Thus if the signal voltage is less than the diode forward voltage, the resultant field of magnet 28 and coil 12 will deflect the armature to a position within less than 90 degrees of the centre zero position. For higher input voltages, one of the coils 18, 22 produces a field in opposition to the field of magnet 28. This produces further deflection and when the field of coil 18 or 22 exceeds that of magnet 28 the deflection becomes more than 90 degrees from the zero position. The totoal range of deflection can thus be made to approach 360 degrees. Fig. 1 is purely diagramatic. Fig. 2 (not shown) depicts a practical construction in which a non- metallic, e.g. plastics, body surrounding the armature is wound with two perpendicular coils one of which constitutes coil 12 and the other of which is a bifilar winding constituting coils 18 and 22.

The end of the pipe 16 is covered by a gauze screen 18 to prevent entry thereinto of foreign matter.
Patent GB-1120489-A (GB)
Title: Improvements relating to alcohol-soluble colour salts derived from metallised azo dyes and their use
IPC: C09B45/14
Filed: 1966-12-09
Abstract: The invention comprises alcohol-soluble colour salts comprising a dyestuff anion moiety which is the anion of a Cr or Co complex of an at least tridentate complex-forming azo dyestuff, which contains no groups which dissociate acid in water and do not take part in the complex formation, and an ammonium alkyl-polyalkyl-polyhydrophenanthrene. Preferred anionic Cr or Co compounds for use in the above process are those containing per Cr or Co atom either two tridentate complex-forming azo dyestuff molecules or one molecule of a more than tridentate complex-forming azo dyestuff, e.g. a tetradentate-complexing azo dyestuff, preferably in combination with one bidentate ligand free from chromophoric groups. Preferred amino-alkyl-polyalkyl-polyhydrophenanthrenes are dehydro-, dihydro- and tetrahydro-abietylamine. Examples are given for the production of the salts.  Printing inks are formed from the alcohol-soluble colour salts by mixing them with oxygen-containing polar organic solvents such as alcohols, ethers, ketones, esters or halogenated hydrocarbons together with conventional additives such as wetting-agents and polyethylene wax anti-blocking agent.  An Example (43) is given in which a colour salt is mixed with shellac, dibutyl phthalate and ethanol.

Title: Apparatus for monitoring binary coded messages
IPC: G06Q10/02
Filed: 1969-11-14
Abstract: 1,236,292. Monitoring binary coded messages. COMPUTER SCIENCES CORP. 14 Nov., 1969 [23 Sept., 1969], No. 55861/69. Heading G4T. Binary coded messages, e.g. those transmitted in the seat reservation system described in Specification 1,235,944, are received and stored in a memory, and may be withdrawn from the memory, converted to analogue form and displayed alpha-numerically so that inspection of the display can reveal any faults in the system using the messages and can indicate the location of these faults. As shown, the messages to and/or from a central computer 12 on any one of channels 14, 14a, 14b can be fed into a bit sequencer 27 by means of switches 21, 25, 26. Each message includes a number of characters, each comprising a number of binary bits. Six data bits are fed by sequencer 27 to positions B to 1 and a parity bit to position C. A starting bit initiates a clock 44. The data bits are transferred to data set 31. If the parity bit C is wrong, alarm 37 is activated. Reception of the parity bit in C of sequencer 27 causes a signal to be sent along line 35 to logic 36. On receiving this signal and the first gating signal (73, Fig. 2) from the clock 44, logic 36 initiates transfer of the data bits from set 31 to register 38. A counter 50 conditions write logic 41 for transferring the data in register 38 to its correct position in a memory 42. A third gating signal (74) then passes via logic 36 and a counter 53 to write logic 41, which effects the correctlypositioned storage of the data in memory 42. A signal (76) from counter 53 to read logic 57 results in data passing from memory 42 along line 59 to register 38, which has itself been conditioned to receive this stored data by the second gating signal (71), transmitted via logic 36. The data retrieved from the memory is then decoded at 61 and converted into an analogue representation at 63. Logic 48 on reception of both a signal (77) from counter 53 and a fourth gating signal (72) from clock 44 then causes alpha-numeric display of the analogue representation on CRT 65. If prolonged inspection of the display at 65 is desired, a hold 68 may be operated to prevent the data stored being replaced by new data.

Abstract: 1,206,840. Measuring charging and discharging properties. RHONE-POULENC S.A. Dec.4, 1968 [Dec. 4, 1967; May 7, 1968], No.57656/68. Heading G1U. An apparatus for measuring the electrostatic charging and discharging characteristics of plastics material, i.e. the maximum charge the material may acquire by corona charging effects and the rate at which such charge will be dissipated, incorporates an earthed support plate 1 rotatable about an axis 2, with a conductive apertured cover plate 23 secured to the support plate, the support plate being rotated by the motor 21. A wire type charging electrode 4 and disc type measurement probe 5, spaced from the charging electrode, are positioned adjacent the cover plate, to overlie the apertures, when the plate is rotated. A high potential is applied to the charging electrode, to charge samples of plastics material mounted on the support plate by corona discharge through the apertures as the plate is rotated, the charging electrode subsequently being earthed. The charge acquired and retained by the material is detected by the measuring probe, which is connected to measuring apparatus such as an electro-meter. In an alternative arrangement, Fig.4 (not shown), the charging and measurement probes are positioned below the rotating support plate, the apertures being in the support plate. The rate at which charge leaks from the material is detected by passing the output from the measurement probe to a meter and measuring the time taken for the output to fall to say 50% of the original value. This may be done by means of a contact in the meter set to the required 50% level, which operates to gate pulses from a counter.

Filed: 1970-12-22
Abstract: 1373629 Copying lathes HEPWORTH IRON CO (ENG) Ltd 24 Jan 1972 [22 Dec 1970] 60987/70 Heading B3T In a stylus controlled copying lathe in which a number of successive passes are made in machining a workpiece, the final pass being wholly under the control of the template, all preceding passes being controlled by a time delay means which is effective from the first point of contact between the stylus and the template and which allows the stylus to continue beyond this initial point of contact when the stylus may be out of contact with the template, to permit the machining of the portion(s) of the workpiece which are encountered at the predetermined depth of cut during each pass. The template 20 is supported from the lathe bed 10 and the copying unit 13 is mounted on the cross slide 15 on saddle 12, the unit 13 carrying the cutting tool 19 and the stylus 23 which is engageable with the template 20. In operation start button 39 is pressed to actuate solenoid Sl to allow the servo valve 58 to advance the copying unit 13 to bring the stylus towards the template. Prior to contact between the stylus and template, a stop on indexable stop drum 48 carried on the unit 13 actuates a stop bolt and the drum and a coaxial spindle 46 are moved axially relative to the unit 13 which brings it to a stationary balance position with the cutting tool 19 at point B as shown in Fig. 2. A limit switch LS1 is simultaneously actuated to allow the saddle 12 to be advanced and limit switch LS2 is set ready for initiation of retraction. When stylus 23 makes initial contact with the template 20 at point C on the shoulder 30 the stylus lever 57 is deflected and takes over the control of the servo valve from the stop drum and a slight retraction of the copying unit initiates operation of a time delay TD1 which has been manually preset by way of a dial (see Fig. 3), which sets the time to traverse from point C to point D on the step 33,  the copying unit being under the control of the stop drum once the stylus has left the point C 1  at the back of the shoulder 30. At the completion of the set period the control unit is retracted to point E and the stop drum is indexed to bring the next stop into alignment with the stop bolt and the saddle is rapidly traversed back to return the stylus to point A. The first pass having been completed, the control circuit is energized to commence the second pass in which the tool is advanced to point F and a second time delay TD2 is initiated. In the embodiment described up to eight passes may be selected each indicated by means of a lamp IL1 to IL8, the final pass being controlled wholly by the template from a rotary selector switch 36.
