Title: Reduction of combustion chamber deposits in gasoline engines
IPC: C10L1/24
Filed: 1960-01-06
Abstract: A gasoline containing a metal-containing antiknock agent also contains a mercury compound as scavenger in a concentration sufficient to provide up to 2,0 gms. of mercury per gallon of gasoline.  The antiknock agent may be a lead alkyl (such as tetraethyl lead, tetramethyl lead, dimethyldiethyl lead or trimethylpropyl lead) or other compound of lead, iron, nickel or manganese.  The mercury compound may be a mercury alkyl, a mercury alkenyl, a mercury aryl, a mercury salt of an aliphatic carboxylic acid, a mercury xanthate or carbonate, a mercury diazoate or diazotate, a mercury salt of a thio acid or of a sulphinic acid, or a mercury nitrosyl.  The mercury compound may contain additional functional atoms or groups such as halogen atoms or hydroxyl groups. Alternatively, inorganic mercury salts (e.g. mercuric chloride, mercuric bromide iodide HgBrI or mercuric phosphate) may be employed, provided they have been solubilized, complexed or dispersed to give solutions or stable dispersions in the gasoline.  The mercury-containing scavengers may be used in conjunction with halogen-containing scavengers (e.g. halogenated hydrocarbons, many examples of which are given, dichlorodiethyl ether, ethyl chloropropionate, ethyl bromoacetate, diethyl dibromomalonate, dichloro-nitroethane, chloro-nitropropane and bromo-hydroxybutane). The gasoline may contain other additives such as upper cylinder lubricants, solvent oils (e.g. hydrocarbon mixtures), corrosion inhibitors (e.g. alkyl acid phosphates, amines, amine phosphates or nitrites and dimerized linoleic acid), gum inhibitors (e.g. N,N1-di-sec. butyl-p-phenylene diamine, 2,4-dimethyl-6-tert. butyl phenol or 2,6-ditert. butyl-4-methyl phenol), anti-icing agents (e.g. isopropanol, hexylene glycol "Carbitol" or dimethyl formamide), dyes (e.g. 1,4-diisopropylamino anthroquinone or p-dimethyl-amino-azobenzene), dye stabilizers (e.g. ethylene diamine) and auxiliary scavengers (e.g. tricresyl, iso-octyl, or methyldiphenyl phosphate).  In the examples, gasoline compositions are described containing (a) tetraethyl lead, di-n-butyl (or methyl isooctyl) mercury, ethylene dichloride and ethylene dibromide, (b) tetraethyl lead, diphenyl mercury and ethylene dibromide or (c) iron carbonyl and mercury petroleum sulphonate.

Title: Improvements relating to valve mechanism for fluid pressure motors
Inventor: BODDY JOHN
Filed: 1949-01-10
Abstract: 668,846. Oscillating-vane motors. TRICOFOLBERTH, Ltd. March 10, 1950. [Jan. 10, 1949] No. 684/49. Class 110(ii). [Also in Group XXIV] A valve mechanism for controlling the flow of fluid to a pneumatic motor contains a coil spring 19 having its upper end secured to a retaining plate 17 which is pivoted on a member, such as a bar 22, the member being adjustable to vary the anchorage position of the spring. This varies the moment when the valve 13 is snapped to one side. The adjustment gives a symmetrical movement to an oscillating vane, or a reciprocating piston, in a casing, which actuates a windscreen wiper. The valve control mechanism may be as described in Specification 545,654. As shown in Fig. 3, a " kicker " is pivotally mounted on a pin 9, which is held in the end of an oscillating shaft 2, a projection 14 passing through a slot in a yoke 16 to engage, alternately, ears on the valve to rock over the valve 13 and reverse the fluid flow to the motor chamber 1. The stepped end 10 of the shaft engages one or other of projections on the face of the kicker, with lost motion, so that after passing over a dead centre, the spring, acting through the yoke 16, causes a snap-action on the valve movement. The spring is secured by a screw 21 on an axially-adjustable bar 22 which is held in position by a screw 23. In a second arrangement, the spring is held by a block which is movable through an arc. In a further arrangement the block is adjustable by means of a threaded rod.

Title: Improvements in and relating to wind-up reel drives
Inventor: BARANY THOMAS ERNEST
IPC: B65H23/198
Filed: 1952-01-09
Abstract: 716,441. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 20, 1952 [Jan. 9, 1952], No. 710/52. Class 38(3) [Also in Group XXXV]  The invention relates to a Ward-Leonard constant-current type reel-motor-control-system compensated for reel diameter and web-speed, to provide a characteristic between that of a constant tension and a constant torque system for winding elastic material such as "Cellophane" (Registered Trade Mark) or cloth. The generator G of a Ward- Leonard set G, M, is energized from an exciter PG, driven at web-speed. The exciter control field e is controlled by a rheostat f operated by a pilot motor i.controlled by a magnetic amplifier k. The amplifier control winding l is energized in accordance with the difference between a reference voltage and the IR drop across resistances g, h in the Ward- Leonard circuit. whereby as the reel builds up and the motor M tends to slow down causing the armature current to rise, pilot motor j operates the rheostat f in the exciter field circuit to reduce the motor current. Thus the voltage across the rheostat varies with the reel diameter, and part of this voltage across potential divider m modifies the reference voltage in the amplifier control winding circuit to cause an increased torque.

Title: Infinitely variable gear
IPC: F16H47/04
Filed: 1959-01-09
Abstract: 897,087. Variable-speed epicyclic gear. WOYDT, E. Jan. 9, 1959 [March 12, 1958], No. 851/59. Class 80 (2). [Also in Group XXIX] A hydromechanical gear providing a variable output speed from a constant input speed comprises an output shaft 9 fast with a planet carrier 11 housing stepped planets 20-22 and a planet 18, and a driving-shaft 5 carrying a sun 6 meshing planet 20 and a ring-gear 8 meshing planet 18. On starting, double dog clutch sleeves 38, 39 are in their right-hand positions clutching gears 35, 33 to shafts 36, 37, respectively, and shaft 5 drives the shaft 37 through gears 6, 20, 22, 23, 29, 33, the shaft 37 driving an hydraulic unit A of the swash-plate type which is adjusted to its zero displacement position. Unit A is hydraulically connected to a similar unit B on the shaft 36, unit B being at its maximum positive setting. The swash-plates are adjusted by cams 54, 55 on shafts 46, 47 geared to a common shaft 52 adjusted by a hand crank 53. With unit A at zero displacement shaft 37 turns idly and shaft 9 remains stationary. On turning shaft 52, the displacement of unit A is increased up to its negative maximum, and then the displacement of unit B is reduced to zero. During this time unit A functions as a pump, driving unit B as a motor and thus driving shaft 36 and gear 35 which meshes a ring gear 13 fast with the planet carrier 11 so that the output shaft is rotated and its speed gradually increased. With unit B at its zero displacement position and shaft 37 of unit A consequently stationary, clutch sleeve 38 is moved to the left to clutch a gear 34 to shaft 36, and the shaft 36 is then driven from shaft 5 through ring gear 8 and gears 18, 25, 30, 34. The displacement of the unit B is now brought gradually to its negative maximum and the displacement of unit A is simultaneously reduced to zero. Unit B acts as a pump and drives unit A as a motor, turning shaft 37 reversely and further increasing the speed of the output shaft 9. Clutch sleeve 39 is now moved to the left to clutch a gear 32 to shaft 37 ; unit A is now driven reversely, and as its displacement is increased, up to its positive maximum, it acts as a pump and drives unit B, the displacement of which is simultaneously reduced to zero, as a motor, rotating shaft 36 in reverse and thereby increasing the output speed up to its maximum value. The clutch sleeves 38, 39 are actuated by cams 42, 43 on the shafts 46, 47.

Title: Signal switching device
Inventor: KADOMA JIYUNYA
IPC: H04N5/44
Filed: 1980-01-07
Abstract: PURPOSE:To avoid the mismatching and the occurrence of reflection to ensure a good isolation, by giving a division between the switch circuit which is terminated by the line impedance and the switch circuit which gives an earth to the leak signal. CONSTITUTION:The TV broadcast signals supplied through the antenna 51 are distributed by the distributor 52 to the TV receiver 53 and the antenna changeover switch 55. And the signal is supplied to the TV receiver 60 through the antenna input terminal 54 of the switch 55 plus the antenna side relays 56 and 58 and via the output terminal 59 each. When the output signal supplied from the additional device 64 is switched to be applied to the receiver 60, the relay 61 at the additional device side is actuated by the selection switch signal given from the device 64. Then the output given from the device 64 is supplied to the receiver 60 through the terminal 59 of the switch 55. The termination of the distributor 52 of the switch 55 is divided to the relay 56 which performs a switching to the matching impedance 57, the relay 61 which introduces the output of the device 64 to the terminal 59 and the relay 58 which prevents the leak given from the terminal 54 each. Thus the mismatching can be prevented.
