Title: Improvements in the regulation of variable-speed power transmission especially for power vehicles
IPC: B61C9/10
Filed: 1949-12-30
Abstract: 674,101. Change-speed control. MAYBACH, K. Dec. 30, 1949 [Dec. 30, 1948], No. 33313/49. Class 80 (ii). In a change-speed , control wherein inputdriven upshift and downshift centrifugal governors 11, 12 operate single-stroke ratchet-pistons 27, 28, turning a distributer-valve 32 supplying gear-shift cylinders 5, 6 with oil-pressure, and the governors 11, 12 are both variably loaded through springs by pistons 61, 62 positioned by a common connection 55 to an engine fuel-control member' 40, so that shift-speeds are automatically reduced with reduction in fuel-supply, the said common connection 55 is subject in one direction only to the action of a delay device, so that when the fuel-supply is reduced, a predetermined period (e.g. 10 secs.) elapses before the governor-loading is correspondingly reduced, whereby undesired downshifts are not caused by temporary reduction in the fuel-supply. The driver's control-pedal 40 operates the engine fuel-pump control 54 and the shift-governor loading-rod 55 through integral cams 43, 44 respectively, and the one-way delay device comprises a piston 74 positively linked to the rod 55 and carrying a free disc-valve 76, which allows free downward movement of the piston (fuel-increase direction), by lifting to allow oil to pass freely from its lower to its upper face through openings 75. Upward movement of the piston 74 (fuel-decrease), caused by a cam-follower spring 52, closes the disc-valve 76, feeding oil from above the piston, past a spring-loaded orifice-plate 86, and through an orifice 84 to depress a spring loaded delay-piston 81 at a controlled rate. During the small upward movement of the piston 74 required to depress the delay piston 81 fully, oil is drawn in under the piston 74 from a vented chamber 72 past a spring-loaded orifice-plate 69 and passage 67. After a predetermined delay-period, and providing the driver does not in the meantime depress the pedal 40, the delay-piston 81 reaches its lowest position, where it uncovers openings 92, 93 allowing oil to pass directly from the upper to the underside of the piston 74, which latter then completes its upward movement to reduce the shift-governor loading. On the return downward movement of the piston 74 (fuelincrease) the delay-piston 81 moves upwardly expelling oil through the orifice plate 86 and surplus oil below the piston 74 is returned through the orifice-plate 69 to the vented chamber 72. In Fig. 2 (not shown), for rail-cars, the doublecam 43, 44 is operated through chain-gearing by a hand-wheel and there is also a separate control-lever for increasing the fuel supply independently of. the cam 43.

Title: Improved gasoline composition and multipurpose additive therefor
IPC: C10L1/18
Filed: 1964-08-18
Abstract: A gasoline composition having anti-rust properties comprises a gasoline and from 8 to 320 parts per million based on the gasoline of a mixture of mono- and dialkyl esters of phosphoric acid, wherein the alkyl groups contain from 12-20 carbon atoms per group, partially neutralized with a primary alkylamine (see Division C2).  Effective primary amines include those containing 1 to 5 carbon atoms in the alkyl group which is preferably straight-chained and unsubstituted although it may be branched and contain substituent groups such as hydroxy and halogen.  The preferred amine is n-butylamine.  The alkyl groups of the mono-and dialkyl esters preferably are unsubstituted, have straight chains, contain 13 carbon atoms and the preferred esters are prepared by reacting a C13 oxo alcohol with P2O5.  In combination with an anti-icing agent the composition possesses synergistic anti-icing properties.  Suitable anti-icing agents are isopropyl alcohol, hexylene glycol or a combination of these two. The gasolines may also contain other additive materials such as solvent oils, corrosion inhibitors, e.g. a phosphorous containing dimer of linoleic acid, gum inhibitors, e.g. amines and phenols, dyes, e.g. 1,4-diisopropyl aminoanthraquinone and p - dimethyl aminoazobenzene and dye stabilizers, e.g. ethylene diamine, but will, however, comprise at least 95% by weight of hydrocarbons.ALSO:A mixture of mono- and dialkyl esters of phosphoric acid wherein the alkyl groups contain from 12-20 carbon atoms per group is partially neutralized with less than the stoichiometric amount of a primary alkyl amine required to neutralize the esters completely. Effective primary amines include those containing 1 to 5 carbon atoms in the alkyl group which is preferably straight-chained and unsubstituted although it may be branched and contain substituent groups such as hydroxy or halogen.  The preferred amine is n-butylamine. Preferably the alkyl groups of the mono- and dialkyl esters are unsubstituted, have straight chains, and contain 13 carbon atoms and the preferred esters are prepared by reacting a C13 oxo alcohol with P2O5.  The partially neutralized mixture is used as a multi-purpose gasoline additive (see Division C5).

Title: Improvements in or relating to remote control systems
IPC: G08C23/02
Filed: 1962-09-04
Abstract: 1,013,304. Ultrasonic signalling systems. ADMIRAL CORPORATION. Sept. 4, 1962 [Sept. 11, 1961], No. 33916/62. Heading G4F. [Also in Divisions H3 and H4] A control system which responds to remotely transmitted ultrasonic control signals of a particular frequency and predetermined minimum amplitude comprises a receiving arrangement for converting the control signals into corresponding electrical signals which are amplified in an arrangement including an electron valve. The valve is arranged so that it is in a circuit whose output is decreased for all signals having amplitudes greater than a predetermined level so that the system responds only to signals lying within a restricted amplitude range. Such a system used, for example, in controlling television receivers may receive the ultrasonic control signal (transmitted for example by means of a hammer and rod type transmitter) with a piezo-electric type microphone 6 tuned to the control signal frequency. The signal from the microphone is passed through the stages 10 and 20 of a transistorized amplifier and thence to the stage 30, whose output is transformer coupled to the following stage. This stage contains as part of its collector load a resistor 38, at the collector end of which is a signal by-pass capacitor 39. In the presence of high-amplitude input signals the large load currents passing through the resistor 38 reduce the operating voltage of the transistor 30 and thereby reduce its gain. The output signal from the transformer 40 of the stage 30 is passed to the stage 50, whose output operates the coil 47 of a relay. A large capacitor 48 connected between ground and the collector 52 of the transistor 50 delays the operation of the relay for a predetermined minimum time. The closing of the relay contacts 54 is used to actuate the device 55 and initiate the desired control. The discrimination produced by the circuit with regard to frequency, amplitude and duration of the received control signal makes it very effective in rejecting spurious noise signals.
