Title: Improvements in or relating to railway vehicle weighing machines
IPC: G01G3/14
Filed: 1961-03-24
Abstract: 941,963. Measuring electrically. TELEFUNKEN G.m.b.H. March 24,1961 [March 31, 1960], No. 10816/61. Heading G1N. In weighing apparatus for railway vehicles the bending stress in the rails due to the weight of the vehicle is measured by at least three strain gauges attached at different points between adjacent rail supports, the outputs of the gauges being differentially combined to give an output having a maximum value corresponding to the weight of the vehicle. Fig. 1a shows an arrangement in which 4 resistance strain gauges D1 to D4 are attached to a rail 3 between adjacent sleepers 1 and 2. The gauges are connected in a bridge circuit as shown in Fig. 2, where R1 corresponds to the resistance of gauge D1 the output after amplification appearing across terminals 7 and 8. Strain gauges may be fixed to both rails to measure the axle loading of the vehicle in which case the gauges may be connected as shown in Fig. 3, R1<SP>1</SP> to R4<SP>1</SP> being the gauges on the second rail. It is shown mathematically that it is advantageous to have the spacing between gauges 1 and 2 and gauges 3 and 4 equal and that the gauges 2 and 3 may be mounted at the same point and, if the circuit of Fig. 3 is utilized, combined into one gauge of double the resistance. The gauges may be attached directly to the rail or alternatively to an elastic member 9 Fig. 7 firmly attached to the rail by brackets 10.

Title: Web cutting method and apparatus
Inventor: SCHIEVEN STANLEY RICHARD
IPC: B26D7/28
Filed: 1967-03-08
Abstract: 1,137,696. Cutting apparatus. EASTMAN KODAK CO. 8 March, 1967 [8 March, 1966], No. 10979/67. Heading B4B. High-speed cutting apparatus for a moving web includes a defect detector 10, Fig. 1, which may be e.g. a pin wheel 40, Fig. 2, which develops signals for each detected defect in the web. A predetermined length sheet is chopped from the moving web during each cycle by a chopper 14 driven at an appropriate rate, by a motor 25. When a defect is present, a defect signal, delayed by a delay circuit 22, changes the motor speed so that the defective sheet, e.g. 16<SP>1</SP> is cut to a length different from the predetermined length of a standard sheet 16. Sheets are fed by a high speed conveyer 17 and a slow speed conveyer 18 to a shoot 20. The motor control circuit 24 provides pulse information to a counter 26. When a desired number of sheets has been cut a signal is supplied by the counter to a motor control circuit 24, delaying the chopper by a still greater amount than if a defect had been detected, so that a longer " marker" " or " separator " sheet 16<SP>11</SP> is produced. In a second embodiment 1000 c/s. pulses from a generator 35 are fed to a length control circuit 36, a modulator 37 and power amplifier 38. If a sheet length is to be reduced the circuit 36 adds pulses to the pulse train during the chop - ping phase.

Title: Improved process of and apparatus for treating metalliferous pulp
IPC: C22B11/10
Filed: 1923-04-23
Abstract: 196,922. Thayer, R. May 1, 1922, [Convention date]. Density separators.-Metalliferous pulp is passed through a centrifugal separator and the separation of the metals is aided by the passage of an electric current across the stream of pulp to a retentive cathode such as mercury. The separator is carried by a frame the parts 10, 11, 12 of which are spaced apart by sleeves 13 on the side bolts 14. One bolt is larger than the other so that the upper frame member 10 may be turned round to permit access to the internal parts. The separator bowl consists of a rotary cylindrical casing 15 with flanged caps 17, 18 at its upper and lower ends respectively. The boss 19 which forms part of the cap 17 receives the end of the pulp feeding pipe 21 which carries a valve 23. Openings in the cap 17 for the introduction of material into the drum are normally closed by plugs 24 and draining openings in the lower cap 18 are closed by plugs 25. The cap 18 has a deep annular groove 26 and carries, above an insulating washer 32, a tubular deflector 31 which communicates with the hollow spindle 27; these parts are held together by the rod 34 and spiders 35, 36. Within the bowl is a dome shaped deflector 39 with a tubular extension 38 separated by insulation from the upper cap 17. Current supply is connected by the leads 50 and spring-pressed brushes 48, 49 to the cap 17 and the deflector 39. A quantity of mercury is introduced into the bowl and during rotation this creeps up the wall 15 and forms the cathode while the deflector is the anode. The pulp mixed with water is supplied through the pipe 21, at a pressure which can be varied by manipulation of the valve 23, and passes between the deflector 39 and outer wall 15, then up to the top of the tubular deflector 31 and discharges through the lower spindle 27. During its passage the pulp is subject to centrifugal and electric action. Platinum, iridium and the like are entrained and held by the mercury, and gold or silver become amalgamated with the mercury. The machine is stopped and the mercury withdrawn and the metals separated from the mercury by washing or distilling.

Abstract: 1333861 Regulating I.C. engine fuel injection PHYSICS INTERNATIONAL CO 23 April 1971 [30 April 1970] 11204/71 Heading F1B [Also in Division G1] In an intermittent fuel injection system for an I.C. engine Specification 1323134 (see Division G1) the fuel/air ratio is maintained inversely proportional to engine speed by a control system 22 providing a signal to open fuel injection valves 18A-N for the duration of a predetermined angular displacement of the crankshaft which signal is modified to compensate for errors arising due to the compressibility of air which falsifies the measurement of mass air flow by a Venturi 40 at the engine air intake, and due to the variations of fuel density with temperature and also to provide the correct fuel/air ratio for light engine loads when the fuel pressure supplied to the injection valves is at its predetermined lowest value e.g. 20 p.s.i. whereby the duration of opening of the injection valves is correspondingly modified. The fuel pressure is controlled by a spill valve 20 having a diaphragm 24 attached to a poppet valve 26-30 and actuated by the difference in pressure between the Venturi throat 44 and the air intake 38 which difference is proportional to the square of the mass flow of the inake air and is measured by a first pressure sensor 60 having a magnetic core 62 on a diaphragm 60D and a winding 66 producing an electrical signal P dv  to a computer Fig.2 (not shown). A signal P fa  representing injection fuel pressure is produced by a second sensor 72 similar to the first and connected between the spill valve and a point in the intake manifold downstream of the throttle valve 42. A third pressure sensor 54 is connected to measure the pressure drop between the air intake and the idling channel 50 and provides to the computer an electrical signal designated P dt , representative of the square of the mass flow of the intake air at light engine loading when the onset of laminar flow through the Venturi indicates flow erro - neously. Signals P 1 , T 1  and T f  representative of air pressure and temperature in the filter 36 and fuel temperature respectively are fed to the computer from sensors 96, 98, 100. A switch 140 responsive to movement of the accelerator acts on the output signal from the computer circuit so as to shorten the injection interval at less than full throttle by passing the signal through a potentiometer (39), Fig.2 (not shown).
