Title: Proof Stress Indicators for Stress/Strain Testing Machines
Inventor: POULSON BARRIE KENNETH
IPC: G01N3/06
Filed: 1967-02-15
Abstract: 1,156,243. Determining stress/strain characteristics. INSTRON Ltd. Feb. 14, 1968 [Feb.15, 1967], No.7357/67. Heading G1N. The stress/strain characteristics of a test material obtained electrically is continuously supervised as the load increases to determine when the relationship diverges from linear by a predetermined amount, corresponding to the proof stress value of the load. The linear relationship is represented by the portion of the characteristic 2 (Fig. 1) between two predetermined points A, B. The load on the test material is measured by e.g. strain gauges, connected by a servolink to the slider of potentiometer 7 (Fig.2), whereby the signal voltage at the slider represents the instantaneous stress. The load values corresponding to points A, B and the displacement of line 3 from line 2 are set up on potentiometers 10, 11 and 17 respectively. When the stress reaches the first value A, amplifier 8 emits a signal which energizes clutches 12 causing the slider of potentiometer 13 to follow the load and the slider of potentiometer 14 to follow the extension of the test material. The stress and strain signals being fed to a recorder. When the load reaches the second valve B, amplifier 9 emits a signal which causes a memory circuit 19 to reduce the voltage across potentiometer 13 until the stress and strain signal inputs to amplifier 16 are equal and opposite. A timer circuit including capacitor 28 and resistor 30 subsequently causes switching device 37 to close switch a, whereby the input to amplifier 16 is augmented by the signal from potentiometer 17. When the amplifier input is again zero, indicating the attainment of point 4 on the stress/strain characteristic 2, the signal output from amplifier 16 is differentiated at 33, 34 and indicated as a short pulse by the recorder. The proof stress value of the load is obtained from the record.

Title: Driver circuit for a capacitive load
IPC: B41J2/02
Filed: 1974-02-18
Abstract: 1452176 Capacitive load driver circuits INTERNATIONAL BUSINESS MACHINES CORP 18 Feb 1974 [16 March 1973] 7368/74 Heading H3T In a driver circuit the leading edge of each timing pulse from a source 25 operates a single shot multivibrator 30 to render a switch T1 conducting for charging a capacitive load 10 from a voltage source Vcc and the trailing edge of each timing pulse operates a single shot multivibrator 40 to render a switch T2 conducting for discharging the load into a constant voltage sink. The load can be a piezoelectric crystal 10 operating as an electromechanical transducer and may be used in an ink jet printer where a single drop of ink is produced for each pulse. When the crystal has fully charged via SCR T1, as determined by RC time constant R1 and the crystal 10, the SCR T1 turns off. R3 holds the gate at ground and enables T1 to withstand a higher dv/dt than if the gate were floating. A diode D1 protects the gate of T1 against the relatively high anode voltage of T1. The control pulse from the pulse generator 25 has a longer duration than the period of the singleshot multivibrator 30 and its trailing edge is inverted by an inverter 35 to trigger the singleshot multivibrator 40. Specification 1,089,408 is referred to.

Abstract: 141,487. Sherrington, W. J. March 26, 1919. Lateral-splash guards.-The guard is supported on an antifriction bearing surrounding the wheel hub but carried by radial arms attached to the wheel spokes, and is characterized by the provision of spring suspending-arms which allow the apron to yield transversely to the wheel plane on coming into contact with an obstruction. The apron 1 is made of moulded rubber or like flexible material and is clamped between segmental bars 6, 7, secured by lugs and rivets 10 to a segmental bar 13, which, by means of a series of holes 12, is vertically adjustable on the carrier frame 14, 15, 16. The upper extensions of the two vertical members 16 constitute spring arms, which are secured by lugs 45 to the sleeve of the ball bearing 18, and allow the apron or guard to swing inwardly towards the spokes when meeting an obstruction, and afterwards to spring back to the normal position. The antifriction bearing is carried by radial arms 21, 22, 23, two of which are adjustable in slots 29, and which are secured to the spokes by spring clips 23*, Fig. 2. Alternate methods of securing the radial arms to different types of wheels are described. The ball bearing, Fig. 3, consists of two races 30, 31, and a cage 33 enclosed between two vertical annular members 34, 35 with interfitting horizontal flanges 36, 37. The parts are held together by U-clips 38, Fig. 1. The sleeve carrying the spring arms 16 consists of an elastic split ring 39, reinforced by flanged laminµ 40, clamped by a screw 41 to the outer ball-race. The arms 16 are secured by bolts 43 and split-pins 44 to lugs 45 held by rivets 46 between the ring 39 and the laminµ 40. A ring 42 of felt or leather is interposed between the ring and the ball-race 30 to render the casing dustproof and to retain lubricant. By removing the split-pins 44, the carrier and apron can be readily detached from the antifriction bearing.

Filed: 1957-03-07
Abstract: 864,988. Liquefied gas fuelled lighters. ETABLISSEMENT GENOUD & CIE. S.A. June 6, 1958 [March 7, 1957], No. 7661/57. Addition to 751,504. Class 75(3). A smoker's lighter employing fuel gas, e.g. butane in a liquefied state under compression, comprises a casing 10 in which a container 13 for the fuel is freely suspended by the stem of a discharge valve assembly 14, the valve controlling the flow of fuel to the burner 16, a movable fingerpiece 28 mounted on the top of the casing and interconnecting means extending from the fingerpiece to depress the container and produce relative movement between the valve member and valve seating to open the valve, depression of the fingerpiece simultaneously actuating ignition striker mechanism to ignite the gas. A snuffer cap 31 may also be raised by depression of the fingerpiece. The valve consists of a stem 17 held by a clip 41 within the burner 16 and a valve member 44 held in contact with a seating 45 by the stem 17 under the action of a spring 46. The fingerpiece carries a rod 33 extending through. a guide 34 in the top 25A of the casing 10 which bears on one end of a lever 35, the other end of which is in the form of a ring engaging under a shoulder 39 on the burner valve body so that pressure on the finger piece presses the valve body 38 downwards and since the stem 17 is anchored to the top of the casing, lifts the valve member 44 against the action of the spring 46. Fuel. from the container 13 passes by means of apertures 51 in a prolongation 48 of the valve body to a throat 50 communicating with the underside of the valve member 44. A pad of paper, cottonwool or other absorbent material partly closes the throat 50 so that the fuel is absorbed thereby and escapes as gas, the degree of compression of the pad and hence the size of the flame being regulable by an adjusting screw 55.
