Title: Improvements in or relating to control apparatus for preventing overloading of the engine of vehicles of the internal combustion engine-electric type
IPC: B60L50/11
Filed: 1933-08-15
Abstract: 428,845. Systems for transmitting mechanical power. SULZER FRERES SOC. ANON., Winterthur, Switzerland.- (Assignees of Zingg, E.; 8, Museumstrasse, Winterthur, Switzerland) Aug. 15, 1933, No. 22761. Void [Abridged as open to inspection under Sect. 91 of the Acts, Feb. 17, 1934]. [Class 38 (iv)] Relates to an internal-combustion engineelectric drive for a vehicle in which control of speed is obtained by means of a manually operated controller 8, 9 in the field circuit of the generator and consists in providing an automatically operated overriding control to prevent the prime mover being overloaded. A resistance 39, connected in the field circuit is varied by means of a fluid-operated piston 22, the valves 35, 36 controlling the admission of pressure fluid to the cylinder being operated by solenoids 33, 34. The governor gear operates a switching arrangement. When the load is below maximum the contacts 31, 24 are bridged causing a white light 27 to show and the valve 35 to be opened so that resistance 39 is cut out of circuit. When full load is reached the contact 23 engages contact 25 and the green light shows. When the machine tends to overload the contacts 23 engage contacts 32 and 26 to operate valve 36 to insert resistance into the field circuit and to energize the red lamp 29. Instead of a resistance in the field circuit of the generator an auxiliary field winding may be used or the main winding may be tapped, the fluid pressure device altering the connections or tappings. Alternatively the control may be on the traction motors.

Title: Method of and means for treating exhaust gases of internal combustion engines to render them innocuous
IPC: F01N3/28
Filed: 1929-07-24
Abstract: 338,933. Gaisman, L., and Peachey, S. J. July 24, 1929. Exhaust, dealing with. - Exhaust gases are rendered innocuous by subjecting them to a catalytic reaction in a silencer containing a number of palladium-carrying discs. Air is supplied under pressure from an enginedriven pump through a pipe g to the exhaust manifold c, each disc f comprising two pieces of nickel gauze between which are inserted the pumice pebbles supporting the catalyst and asbestos. The chambers containing the discs f are lined with heat-retaining sleeves f<3>, which may be asbestos cloth, carrying the catalyst, so that the heat of the exhaust gases is retained to initiate the catlytic reaction, the heat of which is also conserved by the sleeves to maintain the action. The silencer chamber may be formed by a series of cup-shaped members a, the partitions a<1> having perforations arranged in staggered relation; the assembly is secured by bolts e. In a modified construction Fig. 2, a worm is fitted in the silencer chamber, the worm being wrapped with palladium carrying asbestos cloth tape and surrounded by a sleeve j of asbestos cloth. According to the first Provisional Specification the catalyst may be finely divided nickel and additional heat may be supplied to the exhaust gases after mixing with air.

Title: Improvements in or relating to electric motor control
Inventor: RUSSELL MICHAEL CUNNINGHAM BAR
IPC: H02P25/02
Filed: 1968-06-19
Abstract: 1,273,544. Control of A.C. motors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY 7 Aug., 1969 [19 June, 1968; 5 May, 1969], No. 29319/68. Heading H2J. [Also in Division G3] An electric motor 11 is controlled so that the phase of pulses derived from its rotor 12 relative to separately generated reference pulses is kept constant by energizing the motor so that its speed is dependent upon the reference pulses, to which pulses are added or subtracted in response to the output of a phase comparator. The motor is one of a number of hysteresis motors phased locked to the reference source whose rotors comprise shutters in a neutron time-of-flight spectrometer. The motor is supplied from a static alternator 14 comprising thyristor switches in series with transformer windings (Fig. 2, not shown), the thyristors being triggered sequentially by a commutator 15 which receives the adjusted reference pulses, to produce a three phase output. The reference pulses are produced by a "clock" 16 and are divided by N at 22 to provide six pulses per revolution, and by 6N at 25 for comparison with once per revolution pulses from a coil 24 which is swept by a magnetic insert 23 in the rotor in a phase comparator 26. The rotor pulses may be delayed at 27 by a quantized number of clock pulses to provide phase adjustment. The comparator 26 adds or subtracts single pulses to those entering the divider 22. The output 22 is connected to the "commutator" 15 via an "amplitude/time" converter 21 which imposes a small delay proportinal to variations in the motor current the purpose of which is to damp out rotor oscillations which are reflected in this current. The reference pulses may alternatively be derived from a computer which may be programmed to produce a number of different speeds and phase relationships. In Fig. 3 (not shown) the "commutator" 15 may be switched to receive pulses from a pickup coil (33) swept by magnetic marks on the rotor (two marks per pole per phase) so that the motor may be accelerated synchronously, and a variable delay circuit is incorporated so that the slip angle, and hence the torque may be adjusted. Alternatively, the pick-up coil may be rotated contrary to the direction of the rotor; the motor would then operate non- synchronously at maximum torque.

Title: Improvements relating to radio receivers
IPC: H04B1/10
Filed: 1935-08-15
Abstract: 461,330. Valve circuits for wireless reception; filter circuits. COLE, Ltd., E. K., aud FALKUS, A. E. Aug. 15, 1935, No. 22969. [Classes 40 (iii) and 40 (v)] In a radio receiver, the whistle due to interference by adjacent wave-lengths or other causes is wholly or in part suppressed by connecting across the path of the detected signal a condenser 3 in series with an inductance 5, the latter being shunted by a variable resistance 6. The effective reactance in the branch circuit 3, 5, 6, is zero at the whistle frequency. When interference is not present, the resistance serves as a tone control, and when the tapping passes its extreme lower position the control knob may open a switch 4. Other branch circuits such as 8 may be tuned to other interfering frequencies. The branch circuit may be interposed between a detector valve V1 and an amplifier V2.

Title: A process for the preparation of an alkenyl acetate
Inventor: KOHLL CHARLES FRANCOIS
IPC: C07C69/01
Filed: 1965-05-31
Abstract: Alkenyl acetates are prepared by reacting a straight-chain olefine (not more than 4C atoms) with an acetate of ruthenium, rhodium, palladium, osmium, iridium or platinum, in the presence of water in a molar proportion not more than ten times or less than half the precious metal acetate used, oxidizing the aldehyde and/or ketone formed to acetic acid, and using the acetic acid thus obtained with oxygen or a molecular oxygen-containing gas to regenerate the precious metal acetate. Ethene, propene and butenes may be used and the preferred proportion of water to acetate is at least the same as or at the most six times the molar quantity, and at least part of the water produced during the regeneration is recycled to the reactor. Acetates of alkali metals, alkaline earth metals and metals of Groups IB to VII and non-precious metals of Groups VIII may be present, together with halides of alkali or alkaline-earth metals as promoters.  The regeneration of the acetates is promoted by the presence of inorganic nitrates or nitric acid, and salts of metals which form redox systems. The process may be continuous or batchwise and the regeneration stage effected simultaneously or separately.
