Title: Multi-ratio drive transmissions
IPC: F16H63/02
Filed: 1977-02-09
Abstract: 1509519 Change-speed control GENERAL MOTORS CORP 9 Feb 1977 [17 Feb 1976] 5309/77 Heading F2D In a transmission providing at least two ratios established by fluid operated devices and including a governor-responsive shift valve for automatic control of ratio shifts a movement of the shift valve to upshift the transmission is accompanied by the immediate application to it of a hysteresis force acting in the upshift direction to reduce the speed at which a subsequent downshift will take place, followed by the delayed action of means for counteracting the hysteresis effect so that after an interval longer than that required to establish the upshift a downshift will be effected at substantially the same speed as that at which the upshift took place. A manual value may be provided for disabling the hysteresis counteracting means in circumstances in which shift cycling would take place. When the apparatus is used with a transmission having more than two ratios it may be applied to the two highest ratios only. In the embodiment described depression a manual selector valve member 27 from the neutral position, shown, to a "Drive" position causes a land b to allow pressure fluid from a source 16 to pass to a conduit 31 and thence through a branch 69, relay shift value 56 and conduit 71 to the low-ratio establishing means 14. A shift signal valve 36 controlling the relay valve has a pair of spools 37, 39 subject to pressure in a chamber 51 derived from a governor 18 at the output of the transmission and to an opposing force determined by the depression of the accelerator of the engine. The latter force is the difference between the pressure of a spring 42 and pressure in a conduit 23 which varies inversely with accelerator depression and acts on differential areas b, c of the spool 39. Leftward movement of the spools 37, 39 results in pressure from the source 16 being communicated through conduits 17, 48 to the relay valve where it displaces the spool 57 to exhaust the means 14 and pressurize the high-ratio establishing means 15 through a restriction 67. In addition, the pressure in the conduit 17 acts in the upshift direction on the difference between the areas of parts b, a of the spool 37 and the pressure in the conduit 23 acts also in the upshift direction on the difference between the areas of parts b, a of the spool 39. The pressure applied to the highratio means 15 has access through a conduit 87 to a chamber 96 where it acts, after a delay controlled by a restriction 88 and an accumulator 89, on a plunger 97 to reduce the magnitude of the speed-responsive pressure applied to the valve spool 37 thereby counteracting the upshift hysteresis forces acting on the spools 37, 39, e.g. completely counteracting such forces at full throttle. The chamber 96 may be vented to exhaust by a valve 99 to eliminate the pressure reducing action of the plunger 97. Depression of the valve member 27 to a "Drive-1" position causes pressure from the conduit 17, reduced by valve 34, to be conveyed by a conduit 32 to the valve 36 to hold low ratio.

Filed: 1966-12-19
Abstract: 1,139,963. Shearing. D. J. WHEELER. 19 Dec., 1966 [18 Aug., 1966], No. 56757/66. Heading B3W. A sheet or plate shear comprises a stationary shear blade mounted on a frame and a movable blade having means for traversing it across the frame to shear a workpiece, the mounting means for the movable blade being supported directly below the stationary blade whereby the compressive forces acting on the stationary blade act through the mounting means to neutralize the opposing forces acting on the movable blade assembly. The shear is used for cutting out welded joints from continuously processed material and comprises a pair of spaced rectangular section knives 6 bolted to the frame 2. A pair of spaced rotatable knives 10 are mounted in a carriage 5 which runs on four rollers 13 in guideways 14 in the frame. The rollers are carried by spindles which project sideways from a centre-plate 12 which passes downwardly and rearwardly of the knives 10. One pair of rollers is directly under the knives 10. The traversing motion of the carriage is obtained from a pair of screws 23 driving ball nuts 24 on the carriage and rotated through gearing by a reversible electric motor 25. Cutter adjustment. The knives 10 are supported by roller bearings 32 on a spindle 31, the ends of which are keyed into eccentric bushes 34. Rotation of the bushes adjusts the knives 10 vertically relative to the knives 6. The clearance between the cutters is adjusted by shims 38 under the heads of the bushes. Work clamps. The work " S " is held at the side which is first engaged by the movable knives 10 by two swing clamps 41 supported on base-plates which are clamped to the frame by bolts 44. The bolts pass through slots in the baseplates so that the clamps can be positioned to suit work of various widths. Bevelling. Further knives set at an angle may be mounted behind the knives 10 for bevelling the edge of the work.

Title: Vacuum display device using cold emission of electrons
IPC: G09G3/12
Filed: 1973-12-10
Abstract: 1443577 Cathode-ray display tubes INTERNATIONAL BUSINESS MACHINES CORP 10 Dec 1973 [29 Dec 1972] 57144/73 Heading H1D A vacuum display device operates by the cold emission of electrons from selected semi-conductor regions of a panel 60 on to the conductive phosphor coated surface 54 of a display screen, the emission of electrons from a region being controlled by the state of an associated bi-stable semi-conductor circuit integrated in the panel. As shown, the device has a metal envelope 56, and the panel 60-provided with connection pins and leads 62, 65, 66-is supported on a ceramic base 61. The panel 60 may be a silicon wafer the surface of which is coated with caesium to give it an electron affinity lower than that of vacuum, and into the surface P-type regions of which excess electrons may be injected by forward biasing a diode formed by the surface region together with an adjacent N-type region. The panel may be formed as a row and column matrix of electron emitting regions to permit  display of any desired light spot pattern, the wafer containing a storage circuit corresponding to and controlling each emitting region, which region is formed by an extension (76, Fig. 3, not shown) of the diffused base region of a transistor and has a central caesium-coated area (78), the storage circuits constituting the elements of a transistor shift register (Fig. 2, not shown). Reference is made to the provision of a quantized grey scale by dividing each electron emitting area into separate regions which may be of different area, and each controlled by a stage of a shift register, whereby the more regions of an area that are energized to produce emission the brighter the light spot. Use of a dynamic shift register permits the display of a moving picture.

A transportable, heat insulated container 1 has an apertured floor 2, the space beneath the floor being supplied with cold air from at least one vortex tube. As shown, two vortex tubes 7 supply cold air to apertured pipes 8 beneath the floor and air is vented from the top of the container through outlets 11. The container is mounted on a vehicle and the vortex tubes are supplied with compressed air from a compressor 4 via a heat exchanger 5 cooled by the air flow caused by motion of the vehicle. Outlets 11 may be closed and air recycled to the compressor through line 14 in which case exchanger 5 is by-passed via line 15. The compressor is driven by a motor 3, e.g. an I.C. engine, which is started and stopped, or has its speed varied, by a thermostat 12 in the container. The hot air from the vortex tubes is discharged through conduits 7<SP>1</SP> and may be used to heat other parts of the vehicle or the container itself, or for defrosting. In the latter case valves 10 are opened to supply hot air to the pipes 8. The air inlets for the vortex tubes may be provided with couplings to enable them to be connected to the compressed air main of a ship.

Title: Input and output emitter-follower current mode logic circuitry
IPC: H03K19/086
Filed: 1967-12-20
Abstract: 1,206,657. Switching and logic circuits. RCA CORPORATION. 20 Dec., 1967 [31 March, 1967], No. 57790/67. Heading H3T. In a logic or switching circuit having complementary output terminals joined respectively to the emitters of two transistors, a load current is switched to one or other of the terminals by switching means operated by the binary input signals which also control an input current switch to control, by means of complementary output signals, conduction of one or other of the emitter-follower transistors; thus under steady state conditions only one of the latter passes current through the common load current path and power dissipation is reduced. In the Figure, current flows through one or other of the emitter-coupled transistors 11, 12 ("input current switch") depending on the value of a binary signal V b1  on the base of 11 compared with a reference signal on the base of 12; this reference signal may be obtained from a temperature-compensated voltage divider (not shown) across the supply. Auxiliary emittercoupled transistors 13, 14 ("load current switch") are driven in parallel with 11, 12 and switch in synchronism with them, connecting the current through resistor 20 to one or other of the output terminals C or C. The signal V b1  may be obtained from a single input emitterfollower 31 or may be the logical sum of a number of such inputs A, B. The output emitterfollower transistors 15, 16 conduct all the time to supply the leakage current of 13, 14 and base current of 11-14. A minimum emitter current of transistors 15, 16 is provided by resistor 37. Multiple fan-in and fan-out is possible due to the high input impedance and low output impedance of the circuit. PNP transistors may be used instead of NPN, and the circuit may be made in integrated form.

Abstract: 1,164,065. Semi-conductor switching circuits supplying complete cycles of A.C. RADIO CORPORATION OF AMERICA. 27 Dec., 1967 [10 Jan., 1967], No. 58657/67. Heading H2H. A load 20 is supplied with complete cycles of A.C. by the control circuit shown in which a triac 15 conducts continuously in the absence of a firing signal at the control electrode 33 of a silicon-controlled rectifier 35, the application of such a signal causing the SCR 35 to conduct at the first succeeding positive half cycle of the supply 10, 12 and so prevent further conduction of the triac 15. With no signal at electrode 33 and a positive half cycle appearing at terminal 10, the triac 15 is made conductive substantially at the start of this half cycle by means of the firing circuit 28, 30, 44. During this half cycle a capacitor 26 charges through a diode 24 to a voltage equal to that across the load 20 until the potential at junction 23 becomes sufficiently negative to cause the diode 24 to become non- conductive. The capacitor 26 then discharges into the control electrode G through an RC circuit whose time constant is chosen so that the triac 15 is made conductive substantially at the start of the negative half cycle following the above-mentioned positive half cycle, this sequence of operation continuing until a signal is applied to electrode 33. Resistor 28 may be replaced by a variable impedance whose value is co-ordinated with the impedance of the load 20. Members 40, 42 may be replaced by a Zener diode. The circuit may be simplified, at the risk of spurious firing of the triac 15, by omitting the members 40, 42, 44, 46, Fig. 2 (not shown).

Abstract: 1336588 Removing sulphur compounds from gases GRILLO-WERKE AG 14 Dec 1970 [13 Dec 1969] 59308/70 Heading C1A A process for removing one or more sulphurcontaining compounds from an industrial gas comprises contacting the gas in an absorption stage with an aqueous suspension of an absorbent comprising (1) an amphoteric component consisting of an oxide, hydrated oxide or hydroxide or aluminium, zinc, iron or manganese or a mixture of one or more of these, and (2) a basic component consisting of an oxide or hydroxide of an alkali metal or an alkaline earth metal, or a mixture of any two or more of said compounds, which absorbent has a degree of hydration of at least 0À6, the aqueous suspension being circulated through the absorption stage, fresh absorbent being added to and charged absorbent being removed from the circulating aqueous suspension. In a preferred form the waste gas is treated with a suspension of hydroxides and or oxide hydrates of magnesium and manganese and, optionally iron, the charged absorbent being regenerated by roasting in the presence of a reducing agent followed by hydration, the absorbent composition being brought as an aqueous suspension in finely divided form into turbulent contact with a waste gas stream and about 110‹ C., the aqueous suspension being recycled into the absorption stage at a separation from a treated waste gas stream and charged absorbent being separated from the other and passed to the regeneration stage, while the corresponding amount of regenerated absorbent is added to the aqueous suspension. Preferably the aqueous suspension has a solids content of 15-50% by weight. Fresh absorbent is preferably added to maintain the pH value of the suspension in the range 6 to 7. The proportion of molar parts may be in the ratio 1 to 10 of MgO to 1 to 4 MnO 2 . A proportion of the absorbent suspension which is tapped off may be passed to a conventional drying operation such as a spray dryer or fluid bed dryer where it is dried by a partial stream of hot waste gas and the sand-like mass passed to a regeneration pad and heated with a reducing agent such as coal, coke, petroleum, natural gas or other reducing gases. Elemental sulphur may also be employed as reducing agent.
