Title: Improvements in or relating to time delay circuits
IPC: H04M3/12
Filed: 1958-10-30
Abstract: 852,797. Magnetic amplifiers. WESTING- HOUSE ELECTRIC CORPORATION. Oct. 30, 1958 [Nov. 5, 1957], No. 34821/58. Class 40 (9). Discharge of a capator 21 in the input circuit of a half-wave resetting magnetic amplifier 40 blocks the amplifier for a predetermined time after which it causes the cross-connected pair of resetting amplifiers 60 and 80 to change from one state to the other. The amplifiers are provided with half-wave negative D.C. energization of phases 0 and #), as illustrated, the phases being 180 degrees apart. An input signal charging capacitor 21 in a # negative half-cycle blocks output from amplifier 40 and permits an input in a 0 halfcycle over terminal 120 to reset amplifier 60 which when once reset is held reset by the repetitive output of amplifier 80. Output at a terminal 110 is half-wave of phase #. When the input signal is disconnected from capacitor 21 its potential falls in a predetermined time until the reset circuit to amplifier 40 is cut off and its resultant output disconnects the reset circuit of amplifier 60, causing reset of amplifier 80 and consequent reversal of output at terminal 110 from # phase to # phase. The input circuit resistor 22 may be variable to alter the delay between removal of input signal and phase reversal at terminal 110.

Title: Improvements in or relating to a Rebounding Hammer Type Hardness Gauge.
IPC: G01N3/52
Filed: 1968-07-24
Abstract: 1,167, 847. Measuring hardness electrically. NATIONAL FORGE CO. July 24, 1968 [Aug. 18, 1967], No.35234/68. Heading G1N. The hardness of the inner surface of a metal tube as measured by the extent of the rebound of a hammer falling from a predetermined fixed height, is determined electrically by coupling the hammer to the slider of a potentiometer during the rebound. As shown Figs. 1, 2, the hammer head 14 is linked by arms 12, 13 to a shaft, coupled at one end by gear-wheel 15 to a motor M, and at the other end to the slider of a potentiometer P. The initial position of the lower ends of arms 12, 13 is determined by screw columns 16, 17 rotated by a crank 23 and sprocket chain 22, the height being indicated on a disc 24 geared to column 16 and calibrated in terms of tube diameter. Gear 15 is coupled via pinion 30 to flexible shaft 31 driven by motor M. The outer end of shaft 31 is located in a slot 33a in a plate 33 and attached to the armature of an electromagnet SOL1 by a spring-loaded link 35. When the magnet is de-energized pinion 30 is disengaged from gear-wheel 15. To initiate a test, push button PB Fig. 4 is operated, energizing relay SD, whose contact SD1 closes the circuit for electromagnet SOL2, rotating wire support 41 and allowing the hammer 14 to fall on to the test surface. SOL1 is energized and motor M raises the hammer until, at a predetermined height, a limit switch LS is tripped by a pin 18 on gear-wheel 15, causing deenergization of SOL1 and motor M. The freed hammer falls and when it strikes the earthed test surface, a silicon controlled rectifier is fired, followed by relay RR which connects a battery into a bridge circuit 48 containing potentiometer P. The bridge output represents the rebound of the hammer head, and is fed to a recorder. The potentiometer P and bridge circuit 48 may be replaced by a differential transformer.

Filed: 1972-07-28
Abstract: 1393935 Automatic control of temperature HONEYWELL Inc 28 July 1972 [5 Aug 1971] 35313/72 Heading G3R A condition responsive circuit comprising a sensing element and a level discriminator is energized from an a.c. source via a switching element controlled by a voltage breakdown device across the source so that it is conductive only when the supply voltage is below the breakdown value. Thus a load controlled by the sensor is switched only when the supply is close to zero voltage and the sensor carries current for only part of each cycle. In the embodiment, a heater is connected across an A.C. supply 11, 12 in series with a fullwave rectifier 21, that provides a supply 1 to a bridge circuit 2, differential amplifier 44 & amplifier 3 via switching transistor Q 1 , which is turned on as the rectifier output increases from zero and is turned off when a four-layer diode 27 across the rectifier 21 breaks down, the diode then conducting until the next current zero. Temperature is sensed by an NTC resistor R 3  in bridge 2, any bridge imbalance causing different conduction of long tailed pair Q 2  Q 3 , and if this imbalance exceeds a pre-determined limit, and diode 27 has not broken down, triac 64 is fired via thyristor 50 and transistors Q 6 Q 7 , and thus energizes heater 13 for the rest of the half cycle. Triac 64 is triggered during the next half cycle (line 20 negative) by Q 7  acting as a diode. If the temperature is at or above the desired value, the amplifier 3 provides no output and triac 64 is not fired.

Filed: 1965-06-15
Abstract: 1,063,542. Monitoring automated production machinery. HANCOCK TELECONTROL CORPORATION. June 15, 1965 [Nov. 2, 1964], No. 25348/65. Heading G4D. The finished parts from automated machinery impinge against a piezo-electric crystal which generates a succession of electrical signals. These signals after a time delay (determined by transistors Q1-Q3, and capacitors C1, C3, C5, C6) cut off transistors Q4, Q5 of a Schmitt trigger so cutting off relay K1. This results in contact K1d closing to enable a counter 60 to count the production cycles of the machinery 10. If finished parts do not impinge on the crystal for an abnormal length of time, the Schmitt trigger starts conducting to open contact K1d and close contact K1c so that a light 64 indicates a fault.

An anchoring plate A, Fig. 1, for a mortar B has anchoring fins 3, Fig. 3 secured to an upper panel 1 having a central boss 2 carrying an annular chamber 5 and apertures 10 in the lower part of this chamber 5 are normally closed by an annular member 12 which is movable away from the apertures 10 by an amount limited by an abutment screw 14 ; the chamber 5 communicates by means of a passage 16 with a powder charge and firing device D operation of which causes the explosion gases to effect relative displacement of the member 12 with respect to the remainder of the anchoring plate so producing an upward displacement thereof and rapid extraction from the ground whilst the member 12 remains supported on the ground. An adjustable venting device E, Fig. 4 (not shown), is connected by a passageway 17 to the chamber 5. The cartridge 21, Fig. 7, is received in a recess 20 in a head 18 screwed into the end of the passageway 16 and the firing pin 29 is spring- loaded by means of a nut 39 which engages a threaded rear portion of the pin 29 to stress the spring 35. The pin 29 is grooved at 42a and a locking member 41 has two parallel apertures 42 so that on retraction of the firing pin 29 by means of the nut 39, a U-shaped pin 43 can be engaged in the apertures 42 and groove 42a to hold the firing pin in its loaded position whereupon the nut 39 is screwed back against an abutment 38 in preparation for firing this being effected by pulling out the pin 43 from a distance by means of a cord. In the event of a misfire necessitating dismounting of the firing mechanism, it is necessary to withdraw the firing pin away from the cartridge and this is effected by means of an auxiliary nut 45, Fig. 11, which is turned from a distance by means of a cord 57 to move the locking member 41, nut 39 and hence the firing pin rearwardly.

Abstract: 782,565. Separating particles or aerosols from gases. UNITED GAS INDUSTRIES, Ltd. March 21, 1955 [Dec. 22, 1953], No. 35593/53. Class 117 In separating particles or aerosols subject to respiratory action from air or other gases, the gas is caused to travel along a determined path under a velocity such that the suspended particles or aerosols fall out of the gas stream according to their respective terminal velocities and are depoited at positions that differ according to their respective masses. As shown, gas is drawn into channel 5 by an impeller 22 mounted on a spindle 21 carrying a speed governor 23 driven from a spring drive 15 which also causes a transparent disc 13 to be rotated through gearing 17, 24, 26 and 10. A counter mechanism 29 for recording the volume of gas passing through the channel is also actuated from the drive 15. The channel has a removable cover 6 and has in its bottom. a transverse slot 14 which allows particles or aerosols of a limited range of sizes, to fall through on to the disc 13 which is protected by a cover 3 hinged to a main plate 1; alternatively, the deposits may be made on a slide, film or plate which travels in a direction transverse to that of the gas. As a further alternative, slides of glass or other transparent material for recording the deposits may be positioned so as to be observed through a microscope. The velocity of the gas stream may be reduced by gradually increasing the crosssectional area of the channel which may be in the form of a spiral and may be rotated so that it acts to draw the gas through it. More than one channel may be provided and the gas stream may be drawn into the channel or channels by a fan or pump driven by an electric pneumatic or hydraulic motor. If the apparatus is used for the mere separation of the particles or aerosols, the deposit may be received into a liquid stream flowing through the channel or channels. Jets of air or gas may be introduced into the channel or channels to apply a winnowing effect to assist the settling out of the particles or aerosols.

Title: Improvements relating to a process for improving the wearing qualities of mechanicaland constructional parts of light metal and for reconditioning worn and damaged light metal parts
IPC: C23C4/02
Filed: 1932-12-16
Abstract: To increase the resistance to wear of mechanical and constructional parts made of light metal, the parts are roughened by cutting screw threads or grooves therein and are then coated with hard metal, e.g. steel, by spraying.  The process may be applied to reconditioning worn or damaged parts such as cylinders or pistons of aircraft, automobile, and similar engines.  A cylinder is reconditioned by cutting screw threads or grooves on the worn or damaged surface, spraying on an excess of hard metal, preferably steel, and then working to the original dimensions.  In reconditioning a worn piston, excess of hard metal is sprayed on after the grooves or screw threads have been cut, the piston being then worked to its original dimensions and the piston ring grooves recut.  The hardness of the coating may be increased by adjusting the composition of the gas mixture employed in the spraying process to increase the amount of scale present in the sprayed steel coating.  Specification 376,117 is referred to.
