Title: Hydraulic punch and stripper
IPC: B21D28/00
Filed: 1950-05-31
Abstract: 673,513. Punching. MUELLER, O. May 31, 1950, No. 13569/50. Class 83 (iv). A punching machine adapted to be mounted alone or with other units on the base of a press for operating on long work-pieces comprises a punch and stripper mechanism in which a main fluid cylinder operates a punch and an auxiliary cylinder is associated with the work clamp a plunger actuating the work clamp having one end in communication with the main cylinder. The main cylinder or piston may be fixed. A cylinder 16 secured to an abutment 14 on a base 10 houses a ram 20 with ports 90, 118. Pressure is supplied to the cylinder 16 by ports 88, 110 leading to a restricted port 114 in front of the ram. The ram carries a head 26 on a slide 30 to which a punch 56 is secured. Guides 62 for a clampplate 60 are mounted on the slide 30 carrying an auxiliary piston 52 which through rods 104 actuate the clamp 60. Ports 96 at the back of the plunger 92 are connected to ports 100 and ports 124 are connected to ports 120. In operation, fluid-pressure through port 88 moves piston 20 and the slide 30 towards the work 74 and pressure through the port 100 moves the plunger 92 which contacts the piston 52 which through rods 104 applies pressure to the clamp 60. Continued movement of the slide 30 performs the punching operation, the slugs being expelled through holes 84. A reversing valve, not shown, is then operated and pressure is admitted to a port 110 through passages 118, 120 to space 50 to maintain pressure on the clamp and through the restricted port 116 to the back of the ram so to withdraw the slide 30 and the punch-bar modification, Fig. 6, a fixed ram 132 moves a cylinder 134 on a slide 138 containing an annular piston 142 contacting plungers 194 applying pressure to the clamp 164. Pressure in a passage 184 moves slide 138 and punch 160 to the left. Exhaust pressure on the opposite side of the ram 132 is restricted and pressure in passage 140 holds the piston 142 against a cover 146. As the slide 138 moves to the left the work 182 is clamped and punched. By operation of a reversing valve pressure is admitted to ports 190, 188, 192 and builds up on piston 142 before the slide moves away from the work. The slide is then moved to withdraw the punch whilst the clamping pressure is maintained. In further modifications double slides and punches for holing each side of a U-section and a single slide for punching both sides of a U-section are described. U.S.A. Specification 2,353,488 is referred to.

Patent GB-572871-A (GB)
Title: Improvements in and relating to electric switches, particularly alternating current contactors
IPC: H01H3/26
Filed: 1943-08-20
Abstract: 572,871. Actuation of switches. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Aug. 20, 1943, No. 13643. [Class 38 (v)] In a contactor switch for A.C. the moving contact member 10 is closed by the energization of an electric motor 16, a spring 23 being wound up in the process ; on de-energization of the motor the spring unwinds driving the motor backwards and the contacts are opened at a slow speed so that the current is broken at the zero of the cycle without the production of a big arc. In the form shown in Fig. 1, the motor operates a wheel 14 through a friction clutch 25 and gearing 19, 21, and a crank pin 13 on the wheel 14 causes the longitudinal movement (with a little tilting) of members 12, 11, 10. The pin 13 moves through 180 degrees from one dead-centre position to the other being brought to a stop by the engagement of member 12 with a stop 57 on the wheel 14. The tilting of member 10 causes the breaking of the contacts 34 before the contacts 33 and the disposition of the contacts is such that each contact 34 is vertically above each contact 33. The movement of the wheel 14 also opens contacts 56, 56a removing the short circuit from a condenser 55 in the motor circuit and so reducing the voltage at the motor terminals at the end of the switching movement. The switch is also adapted for hand operation by a knob 37 which is first rotated, then pushed in or pulled out and then further rotated, there being a modified bayonet-slot connection between the rod 12 and a sleeve 38 surrounding it and between lugs 42, 43 on the sleeve and a surrounding casing. The knob is attached to the sleeve 38.

Title: Improvements in automatic electric current regulators
Inventor: ROBINSON KENNETH ARTHUR
IPC: B23K11/24
Filed: 1958-04-30
Abstract: 854,544. Automatic current control systems. LANCASHIRE DYNAMO ELECTRONIC PRODUCTS Ltd. April 28, 1959 [April 30, 1958], No. 13751/58. Class 38 (4). In an alternating-current regulator, the controlling action of which is dependent on the emission from a cathode heated by an alternating-current proportional to the alternating current to be regulated, the cathode is preheated by an alternating current of higher frequency than the regulated current. In an embodiment, the current through a transformer 4, for resistance welding, is regulated by ignitions 7, 8 controlled through a transformer 13 by auxiliary thyratrons 9, 10 having control grids g1 energized through phaseshifting networks from a centre-tapped transformer 14. A synchronous timer 15 biases grids g2 of the thyratrons to cut-off at the end of each working period of the welding current. A diode 2 has a filamentary cathode energized during the working period from a current transformer 3. The emission current from the cathode is dependent on the R.M.S. value of the welding current and the voltage across a load resistance 5 is fed through an electronic switch 22 to a storage amplifier 6 applying a direct current bias to the thyratrons 9, 10 so as to maintain the welding current constant. The electronic switch is momentarily closed by a signal from the transformer 13 when thyratrons 9, 10 are extinguished so that the emission current is sampled by the storage amplifier when the cathode is at full heat and current flow has ceased. Prior to the working period, the cathode is preheated through a transformer 19 by the output of an oscillator 16 having an higher frequency than that of the welding supply. An electronic switch, controlled by the synchronous timer 15, controls the oscillator 16 during the pre-heating period to maintain the cathode heating current constant by applying a bias to a grid g3 from the resistor 5 through a direct-current amplifier 17. During the working period the electronic switch applies a fixed bias to the grid g3 to block the oscillator 16. A capacitor 20 and a choke 21 prevent interaction between the welding and preheating circuits.

Title: Improvements in or relating to relay or follow-up devices
IPC: G05B1/04
Filed: 1942-10-01
Abstract: 560,331. Automatic control systems. ELECTROFLO METERS CO., Ltd., SMITHSON, A., and HANCOCK, A. L. Oct. 1, 1942, No. 13773. [Class 38 (iv)] [Also in Group XXXVIII] An automatic regulating system comprises a regulator 9-12, a pointer 1 indicating the value of the variable, e.g. temperature, a periodically operated feeler 3 carried by member 2 and a switch 6 set by a power driven linkage to control a reversible electric motor 7 in accordance with the relative positions of the feeler and pointer, the motor being arranged to control the regulator and also to move the member 2 to maintain coincidence between the feeler and pointer. The power driven linkage, similar to that described in Specification 318,308, [Class 135.], comprises a cam 3b actuating a bell-crank 3a for periodically operating the feeler and carrying a link 5, the lower end of which moves up on one or other side of a lever 4 depending on whether the feeler engages the pointer or not. The link, therefore; either trips a catch 32 permitting the switch arm 6a to drop or raises the switch arm. The motor 7 moves member 2 and the feeler to follow the pointer and varies the force of spring 8 acting on a normally balanced lever of the regulator which may be of the kind described in Specification 463,326 or 463,549, [both in Group XXIX]. The arrangement is such that the feeler either withdraws from and drops on one side of the pointer or it engages the pointer it does not overshoot the pointer and drop on the other side. In a modification, a stepped feeler: and relay similar to that described in Specification 363,548, [Group XXXVIII], is used so that the motor is de-energized when the feeler and pointer coincide.

Title: Apparatus for measuring surface stress by x-ray diffraction
IPC: G01B15/06
Filed: 1974-03-28
Abstract: 1460859 X-ray diffraction apparatus COMPAGNIE GENERALE DE RADIOLOGIE 28 March 1974 [30 March 1973] 13866/74 Heading G1A X-ray diffraction apparatus for measuring stress on the surface of a polycrystalline body includes an x-ray source in association with two position sensitive detectors. The source comprises an x-ray tube and is provided with filters, so as to produce a substantially monochromatic beam, and a collimator, and is in an integral assembly with the detectors. These are each of the type having a straight resistive wire inside a gas-filled tube surrounded by a conductive cylindrical wall. The rise-time of output pulses at the outer ends of the wires is dependent on the distance along the wires and is sensed by circuitry including pulse-shaping, cross-over or zero detec-  tion, time-to-amplitude conversion and multichannel pulse height analysis. The inner ends B, C of the collector wires are connected together. For an unstressed sample, the diffracted beams produced by e.g. two sets of lattice planes within the body, may be arranged to be incident equidistantly from the ends B, C and this is sensed by the circuit. When the sample is stressed, its lattice spacing is changed, resulting in a shift of the diffracted beams, Fig. 4. When a calibrational sample, (having a known stress subjected thereto) is available, the positions of the diffraction maxima are detected for this sample and then for a test sample of unknown stress, and the detected positions compared to derive the stress. When no such calibrational sample is available, the test sample is first positioned such that the incident beam is normal to its surface, so as to obtain two symmetrically-disposed diffracted beams and then the source/detector arrangement rotated around a circle, whose axis passes through the specimen surface, to some position at which a goniometric measurement of diffraction angles # 1 , # 2 , and lattice plane angles # 1 . # 2  may be obtained, and compared with the values for the "normal" position by drawing a graph of calculated value of # d <SP>d</SP> (the ratio of fractional change # d of lattice spacing to the spacing d) against F (sin <SP>2</SP>#), the slope of which graph is a measure of the stress on the sample. A modified apparatus, Fig. 5 (not shown) uses co-linear detectors instead of an angled arrangement.
