Title: An improved electrical meter for measuring wattless energy
IPC: G01R11/00
Filed: 1947-03-17
Abstract: 639,837. Supply meters. LANDIS & GYR SOC. ANON. March 17, 1947, No. 7383. Convention date, March 18, 1946. [Class 37] In Fig. 2 there is shown a wattless energy or reactive k.V.A.h. meter which in use records the difference between the total wattless energy and the wattless energy corresponding to a selected power factor value. In Fig. 1 the curve 2 shows the change in speed of a standard reactive k.V.A.h. meter in accordance with change in power factor from 1 to zero. For tariff purposes it is required to record not the total wattless energy but only the wattless energy above a selected power factor value, for example d (0.75); the wattless energy to be recorded is represented by ordinates such as ab connecting curve 2 with straight line 31. The curve 21 is the characteristic which obtains when in an otherwise standard k.V.A.h. reactive meter the phase relationship of the voltage and current fluxes is changed so that the meter ceases to register at power factor d. The curve 23 shows how the characteristic registration curve of such a meter is changed by the use of reduction gearing with a velocity ratio of 2: 3. The curve 22 is the theoretically correct registration curve, i.e. curve 2 displaced downwards until it passes through the power factor d. The differences between the ordinates of the two curves 22, 23 represent the errors in a meter corresponding to curve 23. In the practical meter, Fig. 2, the reduction gearing 3 may be so selected that the errors are negligible. If the errors are as shown, Fig. 1, the meter, Fig. 2, will record on counter 4 the wattless energy proportional to the area below curve 23, i.e. for any power factor below d the meter will record the total wattless energy minus a constant wattless energy factor corresponding to power factor d. The meter, Fig. 2, is equipped with a ratchet-wheel and pawl (not shown), so that it cannot reverse if the power factor goes above d.

Title: Improvements in or relating to aeroplane landing gears having a steerable landing wheel
IPC: B64C25/50
Filed: 1940-04-25
Abstract: 539,405. Aircraft undercarriages. MERCIER, P. E. April 25, 1940, Nos. 7489 and 7490. Convention dates, April 25, 1939, and July 5, 1939. [Class 4] [Also in Group XXXIV] In landing gear for aircraft having steerable wheels, the energy for effecting the steering is derived from the movement of rotation of the wheels, the energy being transmitted by hydraulically, mechanically, electrically, or pneumatically operated means. As applied to a single castor wheel 1 to which the transmitting means are hydraulically operated, a roller 12 having a hydraulic pump mounted therein is frictionally driven by the wheel and the pipe system 21, Fig. 4, from the pump, shown at 24, communicates with the cylinders 6 of a pair of pistons 20 the rods of which are pivoted to the ends of a double armed lever 8 which controls the rotation of the wheel shaft 3 through gearing. The centrally pivoted lever 8 is provided with a toothed sector connected thereto which meshes with a pinion on the shaft 3. In the position shown in Fig. 4, the wheel is kept along a straight course. The servomotor is completed by a four-way valve 23, a weighted valve 25 and a reservoir 26. The pipe system 21 is connected in parallel by pipes 27 which a pair of variable tension valves controlled by roller push rods 28 and a cam disc 29. The cam disc 29 and the valve 23 are co-axially mounted and remotely controlled by the pilot. To effect a turn, both these members are simultaneously rotated; liquid is then only admitted to one of the cylinders the liquid from the other cylinder being free to drain into the reservoir 26 by the release of the corresponding cam controlled valve. The wheel and its accessories may be retractable. In the application to a landing gear of two wheels, the vertical controlled shaft of the latter is integral with a casing 36, Fig. 9, which forms the swivel carrier of the axle 35 of the twin wheels and is adapted to house a pinion 14, Fig 6 (not shown) which actuates the hydraulic pump and is itself driven by a chain from the axle 35 and also to house a braking system comprising movable discs 45 and fixed discs 46 with an expansible chamber 47 to which pressure fluid may be admitted. The movable discs are provided with channels for air cooling which align with channels in the hollow axle and the casing 36, air being admitted through intakes 50 in the hubs. As an example of the mechanical operation of the transmitting means, the drive from the axle of the wheels is transmitted to opposite handed worms 56, 57, Fig. 12, which drive through sleeves 60, 61, the brake drums 62, 63, braking of which causes turning of the swivel carrier for steering the wheels. Specification 548,067 is referred to.

Title: Improvements in processes of photographic reproduction
Inventor: HEPHER MARTIN
IPC: G03F7/016
Filed: 1952-03-24
Abstract: 714,106. Photographic reproduction process. KODAK, Ltd. March 24. 1953 [March 24, 1952], No. 7551/52. Class 98(2) A silver image in a photographic emulsion layer is used to destroy imagewise a diazonium compound through the action of a bleaching agent of the silver-dye-bleach type, the diazonium compound either having been originally incorporated into a receiving absorbent support or else diffusing into such support after imagewise destruction, whereafter the diazonium compound is caused to couple with an azo coupler to form an azo dye image. The silver image may be contacted with the receiving support in presence of the diazonium compound, bleaching agent, coupler, and acid, and the receiving support separated after imagewise destruction and then made alkaline, as with ammonia, to cause coupling to form the azo dye. The diazonium compound, the coupler, the bleaching agent and acid may be disposed in the emulsion layer or the receiving support; if the azo dye components are not both in the receiving support the latter may also contain an alkaline compound. Numerous alternative dispositions for the various materials are described. In the preferred embodiment a silver reflex print-on paper is impregnated with a solution of a diazonium compound and bleaching agent after acid stop bath treatment, contacted with another piece of paper containing a layer of gelatin, coupler and alkali for one or two seconds and then separated, to leave a positive image on the gelatin-coupler paper. In a modification diazosulphonates replace the diazonium compounds and coupling is effected after exposure to light or activation as with sodium hypochlorite solution. Seven examples describe, quantitatively, the various alternatives. Multicoloured prints may be made by successive transfers of diazonium images on to paper coated successively with couplers for the desired colours.

Title: Improvements in change-speed mechanism
IPC: F16H3/08
Filed: 1919-03-26
Abstract: 145,827. Moore, S. Bramley-. March 26, 1919. Variable-speed toothed or chain gearing comprises an engine shaft A<2>, primary, secondary, and driven gear shafts B<1>, C<1>, D' in alinement, a countershaft E, and an external double friction clutch A, four forward speeds being produced by moving a pedal-lever from one extreme position to the other, a hand-lever H being operated only between second and third speeds. The shaft B<1> has secured to it a gear B<2> meshing with a gear E<1> fast on the shaft E, and carries a feather-mounted outer driven clutch member B. The shaft C' has secured to it a gear C<2> meshing with a gear E<2> fast on the shaft E, and carries a feathermounted inner clutch member C. The shaft D<1> carries a gear D<2>, which is adapted to slide into mesh with a gear E<3> fast on the shaft E, or is loose and adapted to be clutched to the shaft D<1>. The latter arrangement is necessary when silent chains are used as in Specification 1697/11. The lever H serves to operate the gear D<2>, which has clutch dogs D<3> adapted tu engage dogs C' upon the gear C<2>. The clutch members C, B slide together under the joint action of the lever F and a spring S. They are separated by an adjustable bearing T<3>. For first or lowest speed, the drive passes through members A, B, B<2>, E<1>, E<3>, and D<2>. For second speed, the lever F is released, and the power then passes through members A, C, C<2>, E<2>, E<3>, and D<2>. For third speed, the lever F is depressed and gear D<2> slid to the left; transmission is by way of members A, B, B<2>, E<1>, E<2>, C<2>, and dogs C', D'. For fourth speed, the lever F is released, and there is then a direct drive through clutch members A, C, C<3>, D<3>. Reversed driving may be effected through idlers R, R' connecting gears D<2>, D'. As the cone C is never used for starting, it may have a small angle. The cone B may have a wider angle to facilitate engagement.

Title: Improvements in and relating to bituminous compositions
IPC: C08L95/00
Filed: 1949-03-22
Abstract: An organic oleiphilic base containing at least one basic nitrogen group, for incorporation in a bituminous material to be used to coat a solid material, e.g. a road aggregate, previously primed with an anion-active agent so as to form an insoluble film resistant to the stripping-action of water (see Group V), is formed by the ammonolysis of chlorinated paraffin wax or by the condensation of acrolein or its homologues with ammonia or an amine.  The latter materials may be rendered insoluble by hydrogenating and reacting with less than an equivalent amount of an organic oleophilic acid, e.g. a fatty acid such as oleic acid, a naphthenic acid, or tall oil.  In an example, 22 parts by weight of acrolein are mixed with 90 parts of anhydrous liquid ammonia at a temperature of - 60 DEG  to - 70 DEG  C., and the excess ammonia is allowed to evaporate.  The residue is dispersed in alcohol, 5 parts of Raney nickel catalyst are added, and the mixture is treated for an hour with hydrogen under a pressure of 1000 lbs. per square inch at 100 DEG  C., the low-boiling material being removed under reduced pressure.  The product is insolubilized by heating at 240 DEG  C. for 15 minutes with oleic acid to produce a mixture of oleic acid salts and amides of the polyamine.ALSO:A bituminous composition resistant to the action of water is made by priming a solid with an aqueous solution of an organic or inorganic material which produces an anion capable of forming an organic ammonium salt with an organic oleophilic base contained in a bituminous material with which the solid is subsequently coated.  The solid may be a plain surface of glass, wood, cement, or plaster, or a mineral aggregate, preferably granite or rhyolite.  The anion-producing agent may be a phosphate, particularly an alkali metal acid phosphate, chromic acid, chromates, especially of weak bases, citric acid, citrates of weak bases, organic acids such as gallic and tartaric acids, sulphates p  or nitrates of weak bases such as ammonium sulphate or nitrate, alkali metal bicarbonates, proteins such as egg albumen or casein, or an organic sulphonate.  It is preferably applied in the form of a dilute solution of 1-5 per cent of the weight of the aggregate of a 0.01-0.1 molar solution. Organic bases include oleophilic aliphatic amines, preferably long-chain primary amines with at least 14 C atoms, polyamines such as hexamethylene tetramine, amines derived by the ammonolysis of paraffin wax, or the condensation product of acrolein and ammonia, preferably hydrogenated and reacted with less than an equivalent amount of an organic oleophilic acid such as oleic or other fatty acid (see Group IV (b)).

Abstract: 574,808. Locating conductors. CINEMATELEVISION, Ltd., and WEST, S. S. May 21, 1943, Nos. 8086 and 14884. [Class 37] Apparatus for locating masses of electrically conducting or magnetic material comprises an electrical oscillatory circuit including coupled coils, the circuit being arranged to command or cease oscillation as a result of a change in the coupling of the coils due to a change in the amount of electrically conducting or magnetic material in the vicinity of the coils. In the embodiment shown in Fig. 1 a valve 3 is arranged as an oscillator by back-coupling the tuned anode circuit 1, 6 to the tuned grid circuit 2, 8 by means of the coupling between coils 1, 2. Coils 1, 2, Fig. 2, are arranged as a movable search head and are physically associated so as to have zero coupling. Resistances 4, 7 are adjusted so that the value 3 is on the verge of oscillating. When coils 1, 2 approach a conducting body, the increase in the coupling causes the valve 3 to oscillate and an indication is given in headphones 5. Alternatively a change in amplitude of the oscillation is used to indicate the presence of a conducting body. Several ways of arranging the coils are described, Fig. 3 (not shown). Also means for adjusting the initial degree of coupling of the coils by means of dust cases or auxiliary coils are also described, Figs. 5 and 6 (not shown). Further, the change in anode current due to increased oscillation may be used to operate a relay or may switch on a second oscillator to give an indication.

Class 79(2) [Also in Group XXIV] A bogie for a motor road vehicle comprises an enginedriven input shaft 16, Fig. 1, first and second axles 10, 11, reduction gearing 12, 13 for driving each axle, an interaxle differential gear 14 driven by the input shaft, and a clutch 24 which is movable at will to engage or disengage the drive to the second axle. When the drive to the latter is disengaged, the clutch 24 locks a cardan shaft 20 to the axle casing so that an overdrive at half the normal reduction ratio is provided to the first axle only. The differential gear 14 may be of the spur type and be arranged to divide the torgue unequally between the two axles while the clutch 24 may be disposed between the gearing 12 and the shaft 20 to lock the differential gear 14 solid when the drive to the axle 11 is disengaged. In Fig. 9, a bevel drive to the front axle 10 is driven from a sun wheel 17 while a similar drive to the rear axle 11 is driven from a sun - wheel 18 through the clutch 24 and spur gearing, the input shaft 16 being connected to the planet carrier. In the overdrive position, the clutch engages a fixed member 26. In Figs. 6 and 7, the differential gear includes sun wheels 17, 18 of different diameter so that planet pinions 227 may mesh with shorter planet pinions 127 in the space around the smaller sun wheel. The length of the differential gear and hence of the bogie is less than it would be if the sun-wheels were of equal diameter. The clutch 24 is operated by a spring-loaded toggle mechanism 33...37 to connect a shaft 28, which is driven by a cardan shaft from the shaft 19, with either a worm 13 driving the back axle 11 or a fixed clutch member 226.
