Title: A punching machine
IPC: B21D28/16
Filed: 1967-02-21
Abstract: 1,128,285. Punching. OSTERWALDER A.G. 21 Feb., 1967 [8 March, 1966], No. 8193/67. Heading B3W. A punching machine comprises a pair of relatively movable tool support members adapted to close on one another to effect a punching operation therebetween with one said member moving the other member through a limited distance to a punching position, wherein each member has an associated control element adapted to operate on respective machine control circuit elements when the respective member attains a predetermined position during movement of the members towards the punching position, the sequence of operation of the control circuit elements governing further operation of the machine. The punch 9 is mounted in a plate 3, supported in turn by a sleeve 4 which rests on a cushion of oil 6. The position of the punch is adjusted by spacing rings 7a. The die plate 2a is secured to a bearer plate 2 which has a recess 23 in its upper surface to receive the flanged end 21 of a tubular member 12 which is fixed in the yoke 11 of the press. The flange 21 is retained in the recess by a cover-plate 24, and four springs 25 balance the weight of the bearer plate 2, which can move vertically through the distance 26. A piston 15 attached to a tubular piston-rod 14 is slidable in a cylinder formed by an enlargement of the bore 13, the upper end of which is closed by a cap 17. A quantity of pressurized oil 18 fills the space above the piston. A rod 19 passes through the rod 14 and at its lower end is connected to a bolt 20, the lower end of which projects from the undersurface of the flange 21. At the upper end of the rod 19 is a member 34 which actuates a switch 35. There is a clearance 27 between the piston-rod 14 and the bolt 20. A second switch 33 is actuated by a bolt 31 which passes through a bracket 30 secured to the plate 3.  Operation.-With the plate 3 in its lowest position the switch 33 is closed by the screw 31, and opens as the plate moves upwards. The screw 31 is adjusted so that the switch 33 opens when the gap between the punching tools is equal to the thickness of the workpiece. The switch 35 is normally open and closes as the rod 19 is lifted by the plate 2, after the clearance 27 has been taken up. If there is an obstruction between the tools, then the switch 35 will close before the switch 33 opens, and with both switches closed, the machine control circuit is short-circuited and the machine stops.

Filed: 1922-03-21
Abstract: 177,525. Akt.-Ges. Brown, Boveri, et Cie. March 24, 1921, [Convention date]. Vapour apparatus, arrangements of; phase, changing; polyphase transformers.-In a transformer for feeding polyphase mercury - vapour rectifiers having a number of anodes greater than the number of phases of the supply circuit, the number of secondary phases is increased by phase-combination in such a manner that all the secondary phases are in open star connection and are composed of the same number of different-phased portions of winding, and are therefore similar as regards their voltage, voltage drop, and current. An arrangement for producing twelve secondary phases o<1> - - o<12> from three primary phases OI - - OIII is shown in Fig. 1, and a modified arrangement of the secondary windings is shown in Fig. 3. For the purpose of obtaining an overlapping of the anode currents, the twelve secondary phases may be split up into four three-phase systems D - - 1), with separate zero points o - - o<111>, as shown in Fig. 4. The systems A - - D are coupled together in pairs by interlinking transformers t1, t2, and the two groups thus formed are brought into mutual inductive relation by a third interlinking transformer t3.

Title: Interpretation and measurement of data
IPC: G01T1/36
Filed: 1972-02-23
Abstract: 1395753 Radio-chemical analysis UNITED KINGDOM ATOMIC ENERGY AUTHORITY 14 Feb 1973 [23 Feb 1972] 8433/72 Heading G1A Radio-active nuclides are analyzed by a detector connected to a multi-channel pulse height analyzer, the channels being progressively scanned and the counts converted to analogue signals which are progressively integrated to produce an output which is displayed against the channel numbers. As shown, Fig.3, a radio-chemical analyzer comprises a Li drifted Ge diode γ-ray detector 5 feeding a multi-channel pulse height analyzer having channel count stores 8. At the end of a measurement the stores are scanned to produce a sequential digital output on line 13 which is applied to a printer or plotter 2 and, via a D:A converter 15, an analogue output on line 16 which is applied to a graph plotter 4 either directly to produce a conventional spectrum plot or via an integrator 3 which produces a running total. Those portions of the plot produced from the output of the integrator having an increased slope represent the peaks of a normal spectrum plot and the area under these peaks can therefore be measured directly from the scale of the integrated plot. The constants of proportionality may be determined by measuring the area under one peak by a known method. A scintillation counter may be used as the detector 5.

Title: Improvements in turbine liquid flow meters
IPC: G01F1/12
Filed: 1965-02-26
Abstract: 1,045,007. Rotary liquid flowmeters. SOC. ANON POUR TOUS APPAREILLAGES MECANIQUES AND SOCIETE GRENOBLOISE D'ETUDES ET D'APPLICATIONS HYDRAULIQUES. Feb. 26, 1965 [May 28, 1964], No. 8436/65. Heading F1F. In a rotary liquid flow meter including a helical bladed rotor 1, Fig. 1 rotatable by the flow of liquid through a conduit 2 in which it is mounted, the conduit bore includes a frustoconical section and the rotor is axially displaceable by the liquid flow against resilient means to extend the range of flow rates over which the meter will read within acceptable limits of accuracy. In a meter in which accurate readings are required for small rates of flow and which the rotor blades 1 are relatively long the bore includes a converging conical section 7 downstream of the rotor which is loaded by a spring 4 bearing against a fixed abutment 5. As the rate of flow progressively increases the rotor is correspondingly axially displaced to progressively reduce the clearance J1 between the conduit bore, resulting in an automatic increase in the rotational rate of the rotor at lower rates of flow. In a meter having a relatively short bladed rotor a divergent conical section is disposed upstream of the rotor so that with increased flow the clearance between the conduit bore and the rotor progressively increases to decrease the rotational rate of the rotor. The meter may also include the flexible deflector or deflectors upstream of the rotor described and claimed in Specification 1,044,595 to still further extend the accuracy range of the meter.

Abstract: 672,409. Loud-speaker systems. DIRECCION GENERAL DE YACIMIENTOS PETROLIFEROS FISCALES. April 4, 1950, No. 8500/50. Class 40 (iv). Calling current connects a telephone line through an amplifier to a loud-speaker, the connection being breakable by lifting a receiver off its rest. An incoming call on leads B<SP>1</SP>, B<SP>2</SP> energizes M which operates secondary relay N to energize the power supply J for the amplifier and connect the incoming line to the input H<SP>1</SP> of the amplifier. The caller then speaks through the loud-speaker L to issue instructions or to call someone to the telephone. Relay N also energizes the winding Q of a thermal switch which, after a delay, opens to release N and restore the apparatus to original condition. To prolong the call through the amplifier, switch R is opened. Anyone answering the call lifts the handset D so breaking the shunt through contacts D3, D4 round disconnecting relay P which pulls up to release N and connect the external line to the telephone set in normal manner. If desired, manual switch S can be turned to the bell position S2 to cut out the amplifier and cause an incoming call to ring the bell G. Modifications are described, Figs. 2, 3 (not shown).

Abstract: 1,223,482. Orienting sheet material. JOHNSON & JOHNSON. 22 Feb., 1968 [23 Feb., 1967; 20 Dec., 1967], No. 8648/68. Heading B5B. A continuous method of orienting sheet material in the transverse direction comprises moving the sheet material in its longitudinal direction at an original speed, decelerating the sheet material to a final speed of from 50 to 20%, preferably 40 to 25%, of the original speed and stretching the sheet material in the transverse direction at a stretch ratio of from 2 to 5 times, preferably from 3 to 4 times, the original speed divided by the final speed. The stretch ratio may be from 4: 1 to 15: 1. The deceleration and transverse stretching may be carried out simultaneously, preferably by diverging the longitudinal edges of the material at an angle of at least 120 degrees, preferably from 134 to 152 degrees, to each other. The deceleration may also be carried out by pleating or creping the film in the transverse direction. Tension may be applied in the transverse direction of the material by diverging the edges of the film at an angle of less than 10 degrees while the film is heated to a temperature below the melting point of the material, after which the film may be continuously transversely stretched at an angle greater than 40 degrees, preferably from 80 to 152 degrees. The transversely stretched material may then be stretched in the longitudinal direction prior to cooling. An additional step of splitting the material into a fibre web may be included. The sheet may be either a plastics film, preferably polyolefin, or a plastics netting. Polypropylene and polyethylene films are used in the examples.
