Title: Forward-Reverse Drive Controls.
IPC: B60T7/12
Filed: 1966-09-07
Abstract: 1,160,437. Controlling vehicles. INTERNATIONAL HARVESTER CO. 7 Sept., 1966 [9 Nov., 1965], No. 39919/66. Heading B7H. [Also in Division F2]  A vehicle with a transmission shiftable between forward and reverse drive conditions through a neutral position by a control 126 is provided with means responsive to such movement of the control into or through the neutral position to apply the vehicle brakes and preferably to simultaneously slow the engine to idling speed to avoid snatch in the transmission. Preferably application of the brakes is immediate on the suitable movement of the control 126 whereas release of the brakes is subject to an hydraulic time delay. Engine control.-In the vehicle shown the delivery of a fuel injection pump 22 is controlled by a handle 34 through a link 68, a centrally pivoted lever 48 and a link 46. The engine may be slowed to idling without moving the handle 34, due to the lost motion connection 72 in the link 68, by rotating the lever 48, and hence the arm 32 on the pump 22, clockwise by either depressing a pedal 54, which is connected by a link 58 to a bell-crank 60 engageable by a lug on the lever 48, or by moving the control 126 to the neutral position thereby expanding an hydraulic cylinder 52 into engagement with the upper end 50 of the lever 48. Brakes.-Disc brakes (104) (Fig. 5, not shown) on the transmission output shafts are applied simultaneously through linkage (Figs. 3, 5, not shown) including a normally extended cylinder (90) and a brake booster cylinder (98) by depression of a pedal 78 or by movement of the control 126 into the neutral position when the cylinder (90) is contracted by hydraulic pressure. The brakes may also be applied individually by manual steering controls 26 and 28. Hydraulic selector.-The control or selector 126 is movable in three planes passing through the axis of a control valve slide 122 which is retained in selected axial positions by spring- loaded balls 138 engaging detents in the control valve housing 124. In its central plane, to which it is urged by springs 136, the selector has a starting position 126c in which it actuates an engine starter switch 158, a fast idle position in which the brakes are disengaged and an idle position, shown, in which the valve directs pressure fluid through a by-pass incorporated with the hydraulic time delay (182) (Fig. 8, not shown) to a valve actuator (184) which causes fluid to be directed to the hydraulic cylinders 52 and (90). On movement of the selector from the neutral position the delay (182) delays the inactivation of the cylinders 52 and (90). In its other planes of movement the selector controls the engagement of high and low ratio clutches of forward and reverse drive packs (168) and (170) respectively.

Title: Ferroelectric Ceramic Electro-Optical Device.
IPC: C04B35/50
Filed: 1968-08-21
Abstract: 1,182,870. Light modulators. UNITED STATES ATOMIC ENERGY COMMISSION. 21 Aug., 1968 [14 Sept., 1967], No. 40079/68. Heading H4F. [Also in Divisions C1, G4 and G5] A light modulator comprises a hot-pressed, optically uniaxial ferroelectric ceramic plate 10, Fig. 1, electrodes 14a, 14b, 16a and 16b disposed at major surfaces of the ceramic plate for selectively polarizing the plate parallel or perpendicular to the surface of the plate to align the ferroelectric domains along their crystallographic axes in the direction of polarization and thus vary the opacity of the plate, a light source 20 and a detector 26. The ceramic plate may comprise barium titanate, Rochelle salt, or lead zirconate-lead titanate, having a grain size of at least 2 microns and a high degree of homogeneity. The ceramic plate is normally translucent or nearly opaque since the optic axes of the domains are randomly oriented and scattering occurs. With a field applied between or perpendicular to the major surfaces of the plate the optic axes of the domains are aligned with the direction of light transmission and the plate becomes transparent. With a field applied parallel to the major surfaces of the plate the optic axes are aligned perpendicularly to the light path and the plate becomes opaque due to multiple scattering. The switched area does not relax back into its original domain orientation until an appropriate switching field is applied. The domains at selected locations of a ceramic plate may be switched by means of a matrix arrangement of electrodes, Fig. 5 (not shown) the plate being utilized as a high density storage or logic device or as a display device. Three methods of producing domain switching by a localized perpendicular field in ceramic plates initially uniformly poled normal to their major surfaces are described with reference to Figs. 3a, 3b and 3c (not shown) in one of which a point electrode is moved across a major surface of the plate.

Title: Improvements in or relating to the catalytic reforming of hydrocarbons
IPC: C01B3/38
Filed: 1965-09-24
Abstract: In a process for catalytically reforming hydrocarbons heavier than methane with water vapour at a pressure of 0 to 80 bars, the reforming mixture is preheated to a temperature in the range 430 DEG to 600 DEG  C. and the average rate of temperature rise in the first metre of the catalyst exceeds that in the second metre, respective average temperature rises being 80 DEG  to 120 DEG  C. and 75 DEG  to 100 DEG  C. The feed is preferably a light distillate, and the invention allows a lower preheat temperature to be used without incurring carbon deposition on the catalyst.  The catalyst temperature is regulated by controlling the heating rate, the quantity of catalyst per metre, and the quantity of reaction mass entering the reformer, and to obtain a desired steam ratio (e.g. 2 to 5) the diameter of the reformer is critical for a given pressure and feedstock.  The catalyst is preferably Ni on Mg, Zr, Si oxide carriers, e.g. as described in Specification 1,117,778.

The differential heating, which takes place in an argon atmosphere, is effected by placing the substrate between blocks 4 carrying heating elements 5 and coolant carrying tubes 7. This results in the hotter strips 2 becoming P-type, and the cooler strips 3 remaining N-type. In an alternative method, a continuous N-type film on a flexible dielectric substrate is coated with strips of antimony oxide and irradiated by a light source placed inside the chamber of an argon-filled furnace above the coated substrate. The differential optical absorption results in the coated sections of the film becoming P-type. Contact electrodes are deposited on the terminal strips. Conductive layers are deposited over the junctions between the P-strips and the N-strips in the device fabricated on a flexible substrate.

Abstract: 1,245,394. Logarithmic circuits. E.M.I. Ltd. 13 Sept., 1967 [13 Sept., 1967], No. 41881/67. Heading G4G. [Also in Division H4] A logarithmic amplifier (Fig. 2) includes emitter coupled transistors 22, 23 feeding a complementary transistor 24 having a constant current collector load generated by a transistor 25. The output stage is an emitter follower 26. A stabilizing D.C. feedback loop is provided by resistors 27, 28 and a shunt capacitor 29. The logarithmic characteristic is obtained by A.C. negative feedback via a capacitor 30 and a Zener diode 31 in a rectifier bridge circuit 32, 33, 34, 35. The signal voltage is applied to the Zener diode 31 in the reverse biased direction, the peak signal voltage developed being less than the Zener voltage. The current passed by the Zener diode is an exponential function of the applied voltage, thereby providing an amplifier output logarithmically related to the input. A resistor 36 and capacitor 37 correct for the shunting effect of the diode 31 at higher frequencies. An antilog circuit (Fig. 4) has a Zener diode 72 connected in reverse biased manner in the emitter circuit of a transistor 71. An output load 73 is provided. The peak input voltage at terminal 70 is such that the Zener voltage of diode 72 is never reached or exceeded by the emitter potential of the transistor 71. The collector current of the transistor 71 is thereby related to the antilog of the voltage applied to the terminal 70.

Title: Improvements in or relating to photographic apparatus
IPC: G03B7/083
Filed: 1958-12-30
Abstract: 855,462. Photo-electric control devices. GAUTHIER G.m.b.H.. A. Dec. 30. 1958 [Feb. 22, 1958]. No. 41986/58. Class 40 (3). In photographic apparatus having automatic exposure time regulating mechanism, the exposure time is determined either by the output from a photo-electric device exposed to ambient light, or by an adjustable current supplied to the mechanism from a source independent of the photo-electric device, the desired method being selected by manual operation of a switch. In the lens shutter mechanism shown, when a shutter blade driving ring 3 is released for clockwise rotation by the actuation of a lever r3a, contacts 36, 37 make, connecting a battery 30 to a moving-coil relay 25 which operates, at full-scale deflection of a pointer 29, to energize a magnet 32 which displaces a pawl 20 to free a stop 21 on the shutter driving ring 3 and thus permit closure of the shutter. The time needed for the pointer 29 to reach its fully deflected position, and hence the exposure time, is determined by the biasing current fed to the moving- coil relay by a photo-electric element 16 or by a battery 48, according to the position of a manual selector switch 47 with which is ganged a switch 247. Photo-element 16 has an iris diaphragm 43 ganged for adjustment with the diaphragm 46 of the lens shutter. A variable resistor 49 is shunted across the moving-coil when the battery 48 is being used to allow manual exposure time setting. In a modification, the moving coil carries a plate which covers a number of apertures to control an air brake mechanism which determines the run-off of the shutter actuating member. Also, in exposure time regulating devices in which the duration or magnitude of a controlling impulse from a magnetic amplifier is determined by the D.C. premagnetization of the amplifier, such premagnetization can be effected alternatively by the output from a photo-element or from an adjustable current source. When the output of the photo-element depends upon a source of current or voltage, this source may be used as the independent source.

Title: Oxidation process
Inventor: ASHMEAD DERRICK ROYSTON
IPC: C07C29/48
Filed: 1965-10-04
Abstract: Aliphatic compounds containing the grouping <FORM:1094504/C2/1> are oxidized to the corresponding compounds containing the grouping <FORM:1094504/C2/2> by treating them with hydrogen peroxide in the presence of transition metal ions, a liquid reaction medium containing a dissolved carboxylic acid and a catalyst comprising at least one element from Groups IB or VIII of the Periodic Table. Compounds which may be oxidized are, for example, hydrocarbons and alcohols especially alicyclic hydrocarbons and alcohols having up to 14 carbon atoms in the ring.  When alcohols are oxidized the product immediately loses water to form a ketone.  The process is preferably carried out in the presence of hydrogen and this is conveniently effected by forming the hydrogen peroxide in situ from hydrogen and oxygen.  Preferably, the carboxylic acid is a C2-C5 aliphatic monocarboxylic acid, and it is desirable that an acid stronger than acetic acid, e.g. an inorganic oxyacid, and an additional acid radical is also present. The preferred transition metals are titanium, chromium, cobalt, copper, tin, cerium, lead and iron. Examples are given of the oxidation of cyclohexane to cyclohexanol and cyclohexanone.  Reference has been directed by the Comptroller to Specification 1,041,046.

Abstract: 930,638. Nuclear reactors. A. HUET. Dec. 15, 1959 [Dec. 15, 1958], No. 42673/59. Class 39 (4). Fuel element channels of a nuclear reactor are at least in part conically shaped so as to tend to equalize the rate of heat-exchange between the fuel elements and the coolant. As shown, the channel converges at a point q of high heat release from the fuel rod a, and diverges at a point s of low heat release; the flow rate of coolant in the direction A is thus increased where the channel is convergent and decreased where the channel is divergent. The walls of the channels may be corrugated transversely; these corrugations may be helical, in which case they are interrupted periodically to prevent a gyratory movement of the coolant. The moderator c may be graphite or heavy water.
