Title: An apparatus for detecting splits in tubing
Inventor: NELSON WILLIAM EDGAR
IPC: G01M3/28
Filed: 1968-10-01
Abstract: 1,237,250. 250. Detecting splits in tubing. POLYMER CORP. Oct. 1, 1968. No.46508/68. Heading G1S. Apparatus for detecting splits in tubing 1 comprises a cylinder 5 through which the tubing is continuously passed, a pump 17 for evacuating the cylinder, seals 8 to prevent air entering the cylinder and a vacuum gauge 12 for detecting a change in pressure in the cylinder. The seals 8 which are preferably made of rubber are mounted on glands 7 held on the ends of the cylinder by tie rods 9. The air is evacuated from the cylinder until the mercury 13 in the gauge 12 just fails to touch a contact 14. The tubing is then wound from reel 2 to reel 3 and if a split is present in the tube, the increase in pressure in the cylinder causes the mercury to touch the contact 14 thus completing a circuit through the contacts 14, 15 and switching off the power to the drive for the reels. The circuit also includes a flashing light or an audible alarm bell.

Title: Shock tube reactor
IPC: C01B17/04
Filed: 1964-11-18
Abstract: Acetylene and ethylene are produced by passing high pressure well gas (comprising mainly methane) through a wave reactor containing hydrogen at a pressure lower than that of the well gas, whereby pressure interchange takes place, and passing the resulting mixture, in which the well gas is at a lower pressure than the hydrogen, through a second wave reactor.  The original well gas will normally be at a pressure in the range 600-10,000 p.s.i., and during the reaction the temperature rises rapidly to at least 3200 DEG  F. The wave reactor is described in detail (see Division B1).ALSO:Carbon disulphide, carbon monoxide, sulphur and other chemicals can be prepared from well gas in a shock tube reactor.  The open-ended shock tube (71) rotates within and in the plane of a stationary port ring (24) having driving gas inlets (28), driving gas outlets (5, 6, 7 ...). arcuately elongated well gas inlet manifold (45) and arcuately elongated product gas outlet manifold (55).  In operation, in each half-revolution of the shock tube, well gas is compressed in the tube by means of the driving gas, for example hydrogen.  The process gases reach a temperature of 3200 DEG  F. and the driving gas a pressure of 40 atmospheres.  The reactions involved are CH4 + H2S --> CS2 CO2 + H2S --> CO + S + H2O The reactor may also be used to produce HCN from CH4 and N2.ALSO:Methanol and/or formaldehyde may be prepared at the well site from high pressure oil well gas which contains inter alia methane and oxygen using a shock-wave reactor of novel structure which is described in detail (see Division B1).

Abstract: 984,814. Shearing. B.R.G. S.A. Dec. 19, 1962 [Jan. 19, 1962; July 20, 19621, No. 48002/62. Heading B3W. A guillotine has a fixed blade and a movable blade which is operated by two hydraulic jacks, one at each end of the blade, the jacks being fed independently of each other in such manner that their forces add to each other in certain determinated conditions. The upper blade 36 is mounted on a movable apron 1 which is controlled by two jacks 16, 17 which are independently fed by pumps 18 and 19. Movement of the jacks is controlled by pilot valves 14 and 15 set in the pistons of the jacks. The valve 14 is connected to the end 24a of a knuckle comprising two parts 20 and 24, the part 20 being connected to the junction 1a of the apron 1 and the piston rod 16a, and the arrangement being such that when the angle between the members 20, 24 is less than 180 degress, the valve 14 is open. Control of the valve is by a pedal 49. The apron 1 is connected at 1b to a bell crank 25 pivoted at 25a to the frame, the other end of the crank is pivotally connected to a bar 27 which is attached at its other end to a beam 29. The centre of the beam 29 is connected by a lever 33 to a bellcrank 34 and the lower end of the beam is connected to a rod 30. The arm 34a of the crank is connected to the valve 15, which therefore follows the movements of the point 1b but the initial relative positions of the valve and apron, and hence the starting time of the jack 17 can be modified by moving the bar 30 by means of a handle 43 and pinion 99 engaging a rack 30a carried by the bar 30. This adjustment allows alteration of the angle between the blades 35 and 36, when plates of different thicknesses are to be sheared. Hold-down jacks 46 are automatically set at the required distance above the fixed blade 35 by a cam-bar 52 which is connected to the rod 30 by a rocking lever 78. The jacks 46 are fed with oil from the pump 18 by a circuit which prevents pressure being applied to the jack 16 until the hold-down jacks 46 are clamping the work. The clearance " j " between the blades, Fig. 4, is adjusted by cams 95 which control the positions of support rollers 2 behind the movable blade 36.

Abstract: 1318760 Automatic circuit breaker ELLENBERGER & POENSGEN GmbH 21 Oct 1970 [27 Oct 1969] 50053/70 Heading H1N An automatic circuit breaker has an electromagnet 2 the armature of which carries a projection 15 which latches a contact carrying member 23, movable by means of push-button 19, into the contact closed position. Deenergization of the electromagnet causes the projection 15 on limb 55 of the pivoted armature 5, to move out of its retaining position so that the contact member 23 moves into the contact open position, Fig. 1 (not shown), under the action of compressed springs 35, 39. The contact member 23 has a stepped part 32 which is engaged by a projection 21 on rod 19<SP>1</SP> when the push button is pushed in so as to move it into a position with its contact 26 opposite, but not engaging, fixed contact 27. The contact member arm 24 pushes away the projection 15, this being in its retaining position, in moving to this position, and on releasing the push button the projection 15 engages the arm 24 and pivots it about rod abutments 22 and closes the contacts. Excessive current causes projection 54 of an adjustable bimetal 47, having heating coil 56, to unlatch the projection 15 from the arm 24 of the contact member 23 and open the contacts. Further contacts 43 are carried by a movable contact bridge 40 mounted on a rod 38 which is engaged at its top end by the contact member 23.
Patent GB-507140-A (GB)
Abstract: 507,140. Motors. THORNTON, A. A. (Ruben, S.) Sept. 10, 1937, No. 24706. [Class 35] In an impulse electric motor of the type in which a constant torque is obtained by the use of poles on the rotor and stator arranged so that at any moment different rotor polos will be in different positions relatively to the nearest stator potes, the stator includes a member of magnetic material having at least three pole units distributed about the rotor, the rotor also having peripheral teeth and a contact brush co-operating with a stationary commutator to supply current to each pole unit during an angle of rotation of the rotor lying between 360‹/Nn and 360‹/2N where N is the number of rotor teeth and n the number of stator pole units. The period of energization of the pole units and the extent to which the energization periods of consecutively excited units overlap is determined by the brush width which should be less than 360‹/2N#360‹/Nn. As shown applied to a motor operating a vehicle windscreen wiper, the laminated rotor 18 has eight teeth separated by slots of equal width and the laminated stator 10 has six poles 12 of the same width as the rotor teeth, diametrically opposite poles being excited together as a unit so that in the examples shown there are three pole units. The commutator consists of three interleaved members 27, 28, 29 each of the form shown in Fig. 2, and these are assembled together so that the centre one is plane and the two outer ones oppositely dished. The rotor carries a U-shaped brush-holder 20, the arms of the U being disposed in rotor slots and carrying two electrically-connected brushes 23. Each commutator element is connected to the exciting coils of one of the pole units. Electrical connection to the brush-holder is made by way of a contact spring 32 and a metal washer 31 which clamp the commutator elements. The stator poles carry copper damping rings 35.
