Title: Improvements in grading machine
IPC: C14B1/28
Filed: 1944-08-22
Abstract: 598,297. Linear-dimension gauges. NORTH AMERICAN HOLDING CORPORATION. Aug. 22, 1944, No. 16020. Convention date, June 21, 1941. [Class 106 (ii)] [Also in Groups VIII and XXXVIII] Apparatus for indicating, grading or sorting according to the minimum thickness of an article comprises means for measuring the changes of thickness of the article and transmitting only the decreases in thickness by means of an electric motor to the grading apparatus. Fig. 1 shows a leather blank S which is fed through a measuring device M to a grading and skiving device G. The blank passes through feeding rolls to calipering rolls 2, 2a, the lower one being fixed and the upper one moving spindle 105 against the action of spring 110 in response to changes of thickness. The spindle carries a three-wheeled carriage 125 running in a groove in bridge 120. Downward movement of spindle 105 due to a decrease of thickness is transmitted to bridge 120 and arm 134 causing pinion 141 to rotate and move bar 444 to the right. Movement of bar 444 to the left is prevented by the wedging action of block 145 and roller 151 so that control bar 444 is only adjusted in response to successively decreasing spots encountered by the rolls, spindle 105 moving through carriage 125 without lifting it when a thicker spot is encountered. The blank passes from the measuring device and is conveyed to the grading device where it passes between skiving rolls 4, 4a. The position of roll 4 has been adjusted by bar 63 and wedges 65, 66 moved by an electric motor 500 controlled through an electrical correspondence control system (see Group XXXVIII) from bar 444 so that the blank is skived to a uniform thickness by a knife 5. When the blank leaves the measuring device a switch 412 is operated to return bar 444 to its initial position and when the blank leaves the skiving rolls a switch 521 is operated to return motor 500 to its initial position. Specification 597,880 is referred to.

Abstract: 543,135. Electric motor control. GENERAL ELECTRIC CO., Ltd., and COATES, H. J. Nov. 7, 1940, No. 16213. Drawings to Specification. [Class 38 (iii)] In winding equipment wherein the load may overrun a pre-determined limit at which the motor is stopped a mechanical brake is applied and directional back-out switches permit the motor to be operated to bring the load back to the said limit, locking means prevent release of the whole of the mechanical braking until the motor controller has been moved to a position at which the motor develops a torque preventing the load from moving farther beyond the predetermined limits. The means described comprise the coil of an electromagnetic detent on a hand brake lever in series with switch contacts on the back-out switches and in the controller. The back-out switches are preferably interlocked with a cam on the controller so that each is moved to its "off" position when the controller is moved from its "off" position in a direction inappropriate to the back-out switch actuated.

Abstract: 554,136. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., PEARCE, O. A., and OLIVER, S. H. Dec. 18, 1941, No. 16334. [Class 40 (iv)] In an automatic P.B.X., local calls are established over finder-connector links and main exchange calls over a separate set of finders connected individually to junctions, one of these being started in search of a subscriber's line when the latter has both its line and its cut-off relay actuated. This arrangement facilitates the transfer of main exchange calls and, as described in Specification 554,137, the extension of calls incoming over a particular junction to a particular subscriber at night. Local calls.-Line relay R completes a starting circuit for a link allotted by apparatus 10 and marks the line calling. When the line is found, T stops the finder and switching relay HA pulls up in series with cut-off relay K and is followed by line and release relays A, B. The call is completed over a connector CS. Outgoing main-office calls.-The connector is set by the digit O and in this position grounds finder wiper LFS4 to re-operate the line relay R. Since K is still up, this completes marking and starting circuits for the finder EFS of a junction and when the latter switches through, earth on wiper EFS4 shunts down HA to free the local link. Transferring main-office call.-A substation push button (not shown) is operated to hold the main office and take into use transfer equipment (not shown) which takes into use a local link over'which the third party is called as described in Specification 389,867. If he accepts the transfer, the original local party hangs up and on the release of B, transfer relay TR (not shown) being operated, a circuit is made over connector wiper CS4 for the line relay of the third party whereupon the finder of the junction hunts for his line. Incoming calls.-No details are shown. It is suggested that an incoming call might ring a common bell, switch over the test relay of the finder EFS concerned to an additional bank (not shown) and so modify the starting circuits that the removal of his handset by any subscriber would cause the switch EFS to connect with his line. According to an alternative suggestion, an incoming call would ground the wiper LFS4 in the allotted local link so that the call would be completed in the manner described above for an outgoing call.

Title: Control pulse generator
IPC: G06F9/32
Filed: 1961-05-05
Abstract: 986,667. Pulse generating circuits. RADIO CORPORATION OF AMERICA. May 5, 1961 [May 24, 1960], No. 16480/61. Heading H3P. A system for generating a sequence of pulses comprises a first gating circuit for starting a first pulse, a second circuit comprising delay means or having a finite operating time, fed from the first pulse, a third circuit responsive to the delayed output of the second circuit for starting a second pulse, the first pulse being terminated by means associated with the start of the second pulse. Fig. 5 shows a system for generating a sequence of control pulses for a digital computer. A trigger pulse T is fed from source 78 via a NONE gate 70 to initiate a control pulse CP-1 and set the bi-stable trigger 79 to give a binary zero at output A. Control pulse CP-1 is also fed via a NONE gate 82 to delay line 83. After one ÁS., the output from delay line 83 changes from a binary one to a binary zero. The inputs to the NONE gate 74 are now all zero, hence the output from gate 74 initiates control pulse CP-2 and sets binary trigger 81 to provide a binary one at output C. This disables the NONE gate 70, terminating CP-1. One ÁS. later, the output P of the delay line 83 disables gate 74, terminating CP-2. CP-1 is used to reset the arithmetic register 92 and CP-2 opens gate 91 to transfer data from the register 90 to the unit 92. NONE gate 72 is actuated at the end of CP-2 to initiate CP-3 and set binary trigger 80 to provide a zero at output B. When unit 93 has completed its addition, a pulse R 1  is initiated, resulting in a pulse L being emitted from NONE gate 97. Pulse L operates NONE gate 76, initiating control pulse CP-4 and resets unit 81 which terminates CP-3. Other control pulses are similarly generated, the duration being controlled by the delay line 83 or by the operating time of unit 95. Figs. 1, 2 (not shown) relate to a system for generating a sequence of control pulses all of the same duration, using three binary triggers, four inverters, eight AND gates and a common delay line.

Title: Improvements in circuits for the stabilisation of the mean frequency of a frequency-modulated oscillation
IPC: H03J7/04
Filed: 1946-05-31
Abstract: 619,139. Automatic frequency control systems. PHILIPS LAMPS, Ltd. May 31, 1946, No. 16548. Convention date, March 24, 1942. [Class 38 (iv)] In a system in which a control voltage dependent on absolute deviation of the mean frequency of a frequency-modulated oscillation is used to stabilize the mean frequency, the control voltage is developed across a condenser to which charges of opposite sign are supplied, one dependent on frequency and the other independent of frequency. In Fig. 4, the output of an oscillator MO, frequency modulated by a microphone MC, is combined with the output of a crystal oscillator CO in a mixer stage ML, the difference frequency output of which is applied to a limiter stage LM. The output of the limiter stage is applied to a circuit including a condenser C2, the voltage across which is arranged to be zero when the mean frequency of oscillator MO has a desired value. Deviations of frequency from this value result in a D.C. voltage across condenser C2, corresponding in magnitude and polarity to the degree and sense of the deviation, which is applied over lines l to restore the mean frequency of the oscillator. The voltage across condenser C2 is the result of a charge in one direction in dependence on frequency by a circuit including diodes D1 and D2 and a charge in the opposite direction independently of frequency by a circuit including diodes D3 and D4. Amplitude variations which occur in spite of the limiter stage, variations of any D.C. component present in the output of the limiter stage, and voltage variations of a D.C. source B2 supplying bias to the charging circuits, affect both charging circuits equally and do not influence the voltage across condenser C2. To avoid variations in the voltage across C2 at the lower modulation frequencies, a voltage at these frequencies is obtained through a filter (not shown) and applied ever lines or in series with .condenser C2. Component values and operating data are given.

Title: Improvements in or relating to cathode ray tubes
IPC: H01J29/80
Filed: 1954-06-04
Abstract: 791,432. Cathode-ray tubes. DAVIE,O. H. April 26, 1955 [June 4, 1954], No. 16559/54. Class 39(1). A cathode-ray tube of the kind in which a single beam of electrons is generated by an electron gun 3 and is then divided into two parts independently deflectable by an electrostatic shield provided by a plate 7 disposed substantially parallel to the direction of and in the path of the undeflected beam and between a first or an only pair of deflector plates 8, 8, has, in the region of the envelope beyond the space in which the deflection voltages are substantially effective, a further electrode 9 such as when a voltage greater than the voltage on the final anode 4 of the gun 3 is applied thereto to cause an increase in speed of the electrons in the beam beyond the region of applied deflection. The further electrode 9 can consist of deposit of colloidal graphite, with contact 10, around the inside of the envelope adjacent the fluorescent screen 6 and can be separated from a deposit of colloidal graphite 5 on the inside of the envelope, which can be connected to the final anode 4, by a layer 11 of insulating material, e.g., jeweller's rouge. The further electrode 9 can be formed of separate parts, successively higher voltages being applied thereto, so arranged that the resulting electron beam for the normal range of deflection voltages utilizes substantially the whole of the screen 6 but that interference by collision with the deflection plates 8 is mitigated or avoided. In other constructions the further electrode can be a meshed plate positioned adjacent and parallel to the fluorescent screen 6, or can be a thin film e.g., of aluminium backing the screen 6. The splitter plate 7 can have metal parts, either additional to it or formed integrally with it, disposed beyond the normal extent of the splitter plate to avoid capacity effects. The leads to the deflecting electrodes 8 enter the tube substantially perpendicular to its axis. Specifications 505,026 and 553,131 [both in Group XL] are referred to.

Title: Improvements in or relating to interferometers
IPC: G01B9/02
Filed: 1958-05-23
Abstract: 892,233. Interferometers. GENERAL PRECISION Inc. May 23, 1958 [May 24, 1957], No. 16754/58. Class 97(1). An interferometer comprises a source of electromagnetic radiation, such as light, a beam splitter for dividing a beam from said source into two parallel beams which are incident upon a reflecting body having at least two mutually perpendicular reflective surfaces, so that each beam is reflected from the reflecting body by said surfaces substantially along the path of incidence of the other beam, and means for recombining the two reflected beams to produce an interference pattern. This interferometer may be employed to measure the angle error in such a reflecting body, for example, a cube corner prism, or if the reflecting body has no angle error, or an angle error which is compensated, to determine the angle error as of a wedge prism. As shown, in Fig. 3, a collimated light beam 32 is incident on a transmitting surface 33A of a beam splitter 33, is partially reflected at surface 33B, and then wholly reflected at surface 33C and transmitted at surface 33D, so as to form a beam 35 which is parallel to the beam 36 transmitted by the surface 33B. These beams 35, 36 are successively reflected by the three surfaces of a cube corner prism 34, and are then recombined in a single beam 39, so that the eye 38 in the focal plane of a collimating lens 37 will view an interference pattern representative of the angle error in the cube corner prism 34. Observation of the fringe pattern is carried out for three different orientations of the prism 34 by performing two 60 degrees angular shifts of the prism in the plane of its transmitting face. Alternatively, a camera may be disposed so as to record the various fringe patterns. To provide a numerical indication of the angle error in the prism, a variable wedge angle device, such as a Risley prism, may be disposed in the path of one of the beams 35 or 36. The wedges of this device may be rotated relatively or together, to eliminate the interference pattern caused by the angle errors in prism 34, scales associated with each wedge giving the required measure of the angle error. Instead of measuring the angle error of the cube corner prism 34, the apparatus may be used to calibrate a wedge prism disposed in the light path of one beam as shown at 81 in Fig. 7B. In this embodiment, the angle error of the cube corner prism 74 is nullified by a Risley prism 77, the beam splitter 73 provides two parallel beams, spaced from one another, and an optical element 77 is provided to shift beam 75 parallel to itself before arrival of both beams at the cube corner prism 74. By arranging for one of the beams incident on the reflecting body to pass through a gas, which varies in density across the path, a fringe pattern commensurate with the density variation may be obtained.
