Title: Improvements in and relating to apparatus for measuring short intervals of time
IPC: G04F10/10
Filed: 1933-08-03
Abstract: 422,066. Electric speedometers; timing races; thermionic valve circuits. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.- (Assignees of Lord, H. W. ; 1103, Palmer Avenue, Schenectady, New York, U.S.A.) Aug. 3, 1933, No. 21865. Convention date, Aug. 3, 1932. [Classes 106 (iii) and 106 (iv)] [See also Group XL] The speed or time of a rapidly moving object between two points is measured by causing the object to interrupt in succession two light beams focused on photo-electric receivers to cause, through a thermionic valve circuit, the charging of a condenser. The rapidly moving object 6 intercepts the light beam from the light source 3 focused by the optical system 5 on the photo-electric receiver 1. The interception causes the resistance of the photo-electric receiver 1 to increase, thus causing the anode impedance of the high vacuum electron discharge amplifying device 15 to increase to such an extent that the control grid of the vapour electric or arc discharge device 20 becomes sufficiently positive to cause this device to begin to pass current. The condenser 27 is in the anode circuit of the device 20 and is thus charged by the battery 7 between terminals 10 and 11. When the moving object 6 intercepts the light beam from the source 4 on to the photo-electric receiver 2, the anode impedance of the high vacuum electron discharge amplifying device 16 is increased to cause the vapour electric or arc discharge device 21 to begin passing current to cause the condenser 24 to be charged and the device 20 to cease passing current. The charging of the condenser 27 is thus terminated and the reading of the milliammeter 30, actuated through the high vacuum electron discharge device 29, is a measure of the charge received by the condenser 27 and thus of the time the body 6 takes to pass between the two light beams. The milliammeter can be graduated in units of time or units of speed of the body 6. The condenser 27 and its connections are well insulated so that leakage is very low. The switch 23 can be opened for stopping the flow of plate current in the device 21, and switch 28 can be used for completely discharging the condenser 27 at the beginning of a measurement. Under certain circumstances the condenser 24 and resistance 25 can be omitted.

Filed: 1952-09-04
Abstract: 724,241. Control of several motors. BRYANT CHUCKING GRINDER CO. Sept. 4,1952 [Oct. 5, 1951], No. 22285/52. Class 38 (3) [Also in Group XXIII] Four electric motors 2M, 3M, 4M, 5M for driving the operative parts of a grinding machine (see Group XXIII) are controlled by switches and relays arranged in a low-voltage control circuit so as to enable the machine to carry out an automatic cycle. The control circuit is connected through a transformer 171 with the supply to the motors and includes relays 2m, 3m, 4m, 5m for the respective motors. The closure of a switch 175 acts through the relay 2m to energize the motor 2M to rotate the grinding wheel, and the closure of a second switch 190 acts through the relay 3m to energize the motor 3M to drive a main cam shaft. Cams on this shaft then close a switch LS4 to energize a relay 4m to drive the work spindle motor 4M and also effect controlled movements of the grinding wheel and work carriages. A further cam on the shaft also actuates a switch LS6 to de-energize a relay CR, the contacts 205, 215, 216 of which then serve, respectively, to (a) close the circuit of the relay 5m to drive the motor 5M for rotating a second cam shaft, (b) de-energize a clutch 165 between the motor 3M and the main cam shaft, and (c) apply a brake 166 to the latter motor. Cams on the second cam shaft then effect further controlled movements of the work carriage, followed by actuation of a switch LS7 whereby the relay CR is energized to stop the motor 5M and restart the drive of the first cam shaft by the motor 3M. Further movements of the two carriages under the control of the main cam shaft follow until the switch LS6 changes over the drive to the second cam shaft which, after providing additional movement of the work carriage, actuates the switch LS7 so that the main cam shaft takes over to return the carriages to their inoperative positions.

Title: Improved hydrocarbon radiochemical conversion process
IPC: C10G32/04
Filed: 1957-07-15
Abstract: <PICT:0851541/III/1> C2 to C20, preferably liquid C5 to C20 hydrocarbons are converted to other hydrocarbons, in particular lubricating oil fractions, by exposure to high energy ionizing radiation, the intensity of the radiation being reduced periodically or continuously during the conversion.  Suitable apparatus comprises a radiation source 1, which may be a nuclear reactor or cobalt 60, surrounded by one or more conduits 2 which passes through zones A, B, C formed by reflecting or shielding material 3.  The spacing of the conduit and the amount of material 3 controls the quantity of radiation in each zone.  The hydrocarbon enters zone A at 4, flows progressively through the zones and is removed at 5.  Solvent to control viscosity may be introduced at 6.  Some or all the process stream may be removed at 8 to processing zone 9 where solvents or catalysts may be added or removed, the stream being returned at 10. Temperature control may be obtained by circuit 12, 14 and heat exchanger 13 or heat exchanger 16.  Part of the stream may be withdrawn at 17 for recycle to a zone of higher intensity by line 19. The hydrocarbon stream may contain solvents or emulsifiers such as ethers, ketones, aldehydes, carbon tetrachloride, cholorform and water, inorganic solids such as absorbents and catalysts, and materials giving off secondary radiation on neutron capture or photon incidence.  If the source of radiation is a nuclear reactor the hydrocarbon reactant may act as moderator.  Alternative apparatus may consist of a multi-type multi-pass heat-exchanger type device with reactant on the tube side and fissionable material, as a homogeneous liquid, on the shell side.  In an example cetane was passed through aparatus with four zones similar to that shown and disposed in a nuclear reactor with a core of a homogeneous water solution of uranyl sulphate.  The temperature ranged from 350 to 450 DEG F., the pressure from 400 to 100 p.s.i.g. and the radiation absorbed in the zones being 85, 20, 10 and 5 B.T.U. per pound respectively.  Over 50% of the product was a viscous polymer-like liquid useful as a lubricating oil additive.  Specifications 802,552, 814,562, 823,099 and 823,426 are referred to.
