Abstract: 367,974. Endless belt conveyers. KRI•GER, L., 120, Avenue d'Orleans, Paris. Dec. 23, 1930, No. 38791. [Class 78 (i).] In an endless belt conveyer, distributing means at a despatching station or stations control the feeding to the belt of articles to be conveyed and selecting means in the path of the belt effect either the discharge of the articles, or the transfer to a branch conveyer, the distributing and selecting means being actuated interdependently and in dependence on the speed of the belt. The system shown in Fig. 1 comprises belts B, B<1> running at the same speed, a central distributing station R having four distributing points, a subsidiary distributing station R<1> having two distributing points, and a selector S. Articles fed at the station R are delivered at stations S<1>1 .. S<1>4, and articles fed at the station R<1> are delivered at the stations S<1>2, S<1>5. The distributing points at the station R comprise hoppers 1 .. 4, Fig. 3, having movable sides 5 .. 8. The contents are discharged when the sides are moved by the action of cams 14 .. 17 on rods 9 .. 12. The cams 14 .. 17 are mounted on a shaft 18 driven by the belt B. Cams 22 .. 29 also mounted on the shaft 18 control remotely the station R<1> and the selector members through mechanical, pneumatic, hydraulic, or electrical means. In a modification the hoppers 1 .. 4 are replaced by auxiliary belts 39, Fig. 5, the driving drums 38 of which are driven by toothed sectors 32 .. 35 on the shaft 18. The selector, Fig. 7, comprises a belt 40 passed over rollers 41 .. 45 and a collector 46 which may be a box for' use at stations S<1>1 .. S<1>5, a guide for a branch belt such as B<1>, or a belt. The rollers 42, 45 are moved in opposite directions by the action of a solenoid 51 on a lever 47 which is connected to the rollers by rods 49, 50. The energization of the solenoid is effected by one of the cams 22 .. 29. In a modification the displacement of the rollers is effected by two pulleys mounted on the shaft of one of said rollers and engaging respectively two oppositely disposed belts anchored at one end and provided with tensioning means at the other end, means being provided to neutralize the effect of said tensioning means when the roller has been displaced to its full extent. In another modification, the gap is produced by moving one of the rollers out of the normal path of the belt, and in a further modification, a belt 89, Fig. 11, in the gap is displaced by a solenoid 90.

Abstract: 1321260 Nickel cadmium storage batteries UNION CARBIDE CORP 13 Aug 1970 [13 Aug 1969] 38975/70 Heading H1B To improve the charge retention and acceptance of a nickel cadmium cell, particularly at elevated temperatures, the positive nickel electrode includes a quantity of zinc in excess of the quantity required to saturate the KOH. Preferably, the quantity of zinc is within the range 1À10 to 3À50 times the saturation quantity. The nickel cathode is preferably made by a pressed powder technique in which openings in a metal grid are filled by a two-roll mill. The composition of a preferred powder mixture by weight per cent is: Ni(OH) 2 , 62À00; graphite, 18À60; CdO, 11À90; Zn, 4À90; Dynel, 0À60; H 2 O, 2À00. The zinc may alternatively be present in the form of zinc oxide. The cadmium oxide serves as an anti-polar mass to prevent hydrogen generation at the positive electrode in the event of polarity reversal. The electrode may alternatively be made by a sintering process. In other, less preferred, manufacturing processes the zinc is initially added to the electrolyte or to the negative electrode and is partially transferred to the positive electrode during cycling of the cell. The powder composition of the negative electrode by weight per cent may be: CdO, 86À09; Ni, 13À38; Dynel 0À53.

IPC: E21B43/20
Filed: 1964-09-28
Abstract: 1,009,828. Wells &c. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Sept. 28, 1964, No. 39511/64. Heading E1F. Hydrocarbons are produced from a permeable formation 1 having an injection well 4 and a production well 5 by injecting fluid hotter than the formation into the well 4, producing hydrocarbons from the well 5, and after the fluid has reached the well 5 reducing the pressure within the pores of the parts of the formation contacted by the fluid to a pressure less than that in the pores of the rest of the formation. A line of injection wells may have one or two parallel lines of production wells, or an injection well may be surrounded by production wells. The inlet to the well 5 may be below the bottom of the formation to trap any steam formed. The pressure is reduced by decreasing the flow resistance in the formation about the well 5 by fracturing the formation, by decreasing resistance to flow at the outlet of the well 5, by increasing the pumping rate from the well 5, and by decreasing the rate of injection into the well 4. Drive fluids may be injected outside this area affected by the hot fluid.

Abstract: 1498471 Measuring shaft alignment electrically BENTLY NEVADA CORP 3 Oct 1975 [10 Oct 1974 40570/75 Heading G1N [Also in Division F2] The invention relates to apparatus for measuring the misalignment between two shafts connected by a flexible coupling. As shown, Fig. 2, a driving shaft 17 forming part of a fixed machine is connected to a driven shaft 18 by a flexible coupling 12 comprising two hubs 26, 27, Fig. 3, which are keyed to the respective shafts and spaced apart by a flexible tube 34 carrying a diaphragm 37 at each end. Secured to guard rings 39 bolted to flanges 28, 29 on the hubs 26, 27. The guard rings 39 have four cut-outs 46 in each of which is located a plate 47 rigidly attached by a collar 48 to the tube 34, the inner surface of the plates 47 being perpendicular to the axis of tube 34 and normally flush with the inner face 43 of the guard rings 39. Located near each ring 39 is a vertical yoke 52 carrying four proximity probes 51, e.g. eddy current probes, measuring the distances between the yoke 52 and the locally associated plates 47 or the face 43 of the guard ring 39. Two similar probes 56 mounted on a bracket 57 scan the circumferential surface 58 of the flange 29 which is formed with four notches 59 in line with the plates 47, to produce differential signals which determine whether the probes 51 are facing plates 47 or the faces 43 of the guard rings 39. A mathematical analysis shows how the signals from the light probes 51 can be combined to determine parallel misalignments in the vertical and horizontal planes, and angular misalignments in the vertical and horizontal planes. The signals are combined to determine the modifications in height necessary at the bearing supports of the driven shaft to obtain proper alignment. The probe signals may also be used to determine compression or stretch in the axial direction. An alternative arrangement for measuring radial displacement is also described. The measuring apparatus may be used with a gear-type flexible coupling 151, Fig. 9, comprising a tube 152 with internal gear teeth 153 which mesh with spur gears 161, 162 formed on hubs 156, 157 secured to shafts 158, 159 which are to be coupled.

Filed: 1972-09-01
Abstract: 1402626 Automatic control for I C engines PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 1 Sept 1972 [4 Sept 1971] 40579/72 Heading G3N [Also in Division F1] In a system for supplying an air/fuel mixture to an I.C. engine having its cylinders 2 connected to a common air induction pipe 4 by way of an intake manifold 3, and a fuel supply metering fuel to the induction pipe, a 'tame' differentiator 40 is provided to receive a signal from a pressure transducer 42 located in the manifold 3, the output of the differentiator being arranged to influence the injection period of a fuel metering member which opens into the induction pipe 4 or the manifold 3. A 'tame' differentiator is one which provides a 'tame' pulse which decays exponentially if it receives a stepped input signal such as is provided by the pressure transducer for sudden acceleration or deceleration. Thus, during acceleration, the output of the differentiator acts to increase the injection period of the metering member, which increase gradually decreases due to the exponential effect. During deceleration, the opposite effect is obtained. As shown, the fuel supply is a carburetter which continuously supplies fuel to the induction pipe 4 via orifice 5, and the fuel metering member is an electromagnetic valve 44 which is intermittently operated by an electronic device 43 which receives inputs from the differentiator 40 and various other parameter sensors. In an alternative, Fig. 4 (not shown), the fuel supply is a mechanical injection valve. In a modification, Fig. 5 (not shown), the fuel supply and the fuel metering member are combined as an electromagnetic injection valve which is intermittently operated by the electronic device 43. The action of the differentiator is also made variable with variations in engine speed. The signal from the transducer 42 is applied to the differentiator 40 intermittently, a sampling unit 41 being used to sample the pressure at the instants at which the inlet valves of the cylinders close.
