Title: Method and Apparatus for the Automatic Identification of the Spacing Zones Dividing a Film Strip into Picture Areas or Frames
IPC: G03B21/32
Filed: 1967-02-24
Abstract: 1,183,223. Photo-electric investigation of film strips. AGFA GEVAERT A.G. Feb.24, 1967 [Feb. 25, 1966], No.8873/67. Heading G1A. The spacing zones, dividing a film strip into picture areas, or frames, are located by investigation of the relative transparency of consecutive portions of the film strip using photo-electric apparatus. However, if the picture area is very weakly exposed near the boundary or is a blank, making location of the spacing zones difficult, the apparatus will allow for this. The photo-electric system comprises a light source 6, which, via condenser 7 and lens 8, illuminates a slit 4, of width preferably half that of the narrowest spacing zone to be investigated, and located transverse to the direction of movement of the film strip 1. This is moved along in front of a photo-multiplier 9 by motor-driven rollers 2, 3, in steps of at the most half the width of the smallest spacing zone that will be encountered. Thus, at every step, the output of the photomultiplier 9 represents the transparency of a different portion of the film. The analog detector output is converted into a digitally-coded signal by a converter (15, Fig.3 not shown), which is then processed by a specialized digital computer. Firstly, a particular portion is located which has the maximum (in the case of negative film) or minimum (in the case of reversal or borderexposed films) transparency encountered withina number of steps. When such a maximum (or minimum) value has been located, further steps are executed, and if a film portion at which a change in transparency greater than a predetermined amount occurs within a first predetermined number of steps this portion is a leading picture boundary and the maximum located is a spacing zone. This zone will be marked by a marking punch 11 when it reaches the marking mechanism. If the boundary is not located within this predetermined number of steps from the location of the maximum or minimum, the picture area must be a blank or have a very weakly exposed boundary area. To differentiate between these, further steps are executed and if there is no transparency change greater or less by another predetermined amount than the value at the spacing zone, the picture is blank and no marking is carried out. If there is such a change the picture in the area of the boundary is very weakly exposed and the previously located maximum (or minimum) is marked. The computer circuitry operates by going through a sequence of instructions after each transport step of the film which include holding the current transparency value in a store (16), comparing this value with the most recent maximum transparency value obtained and held in a further store (17) and depending on whether the current value is greater than, equal to or less than the previous maximum, following through further instructions.

Title: Electrical power supply system
Inventor: BORDEN JAY R
IPC: H02J9/06
Filed: 1966-03-01
Abstract: 1,109,212. Alternative power supply systems. BORG-WARNER CORPORATION. 1 March, 1966, No. 8900/66. Heading H2H. An electric power supply system wherein an output circuit 12 is normally supplied from an A.C. input circuit 11 by way of a rectifier 10 has means provided whereby should a transient failure of the A.C. supply occur the output circuit is supplied from a battery 13 but that should the failure persist for longer than a predetermined time (e.g. 2 seconds) the supply from the battery is interrupted in order to protect the battery. When a failure of the A.C. supply occurs a switch 29, which is normally a thyristor, closes whereupon a circuit to the output circuit 12 is completed from the battery 13 by way of a circuit device 17. The signal developed in the device 17 is applied to an amplfier 18 to close a switch 34, which may be a further thyristor. Relays 20, 21 are then energized from the output circuit 12 by way of contact 28 of a relay 26 in a voltage sensing means 16 and the switch 34. Energization of relay 20 closes contact 24 whereupon the output circuit 12 is supplied directly from the battery 13. Should the failure of the A.C. supply persist for longer than the predetermined time, the energization of the relay 21 closes a contact 31 which is given a delay equal to that time. A relay 22 is then energized to open contact 33 then interrupting the supply from the battery to the output circuit. Should, however, the A.C. supply be restored before contact 31 closes, the relay 26 is energized opening contact 28 and de-energizing relays 20, 21. The system then is returned to normal with the output circuit 12 supplied from the A.C. supply by way of the rectifier 10.

Title: Isotopic enrichment of uranium with respect to an isotope
IPC: B01D59/30
Filed: 1974-02-27
Abstract: 1467174 Isotopic enrichment of uranium COMMISSARIAT A L'ENERGIE ATOMIQUE 27 Feb 1974 [27 Feb 1973] 8918/74 Heading C1A Uranium isotopic exchange is effected by contacting a compound of UIII with a compound of UIV unreactive therewith, at least one of the compounds being in a liquid phase and the other being in solid or liquid phase under conditions such that no net transfer of U in either valence state or oxidation of UIII occurs whereby UIV compound becomes enriched in the lighter isotope and separating the compounds. In a preferred embodiment an aqueous phase, e.g. UCl 3  in HCl is contacted with an organic phase containing UIV in a multistage extraction, the isotopically enriched UIV is extracted from the organic phase leaving the last stage of the cascade into the depleted aqueous phase leaving the first stage, the U content of the resulting aqueous solution is reduced to UIII and the solution is recycled to the last stage of the exchange cascade and conversely oxidizing depleted UIII in aqueous phase from the first stage to UIV, transferring it to the organic phase which has been depleted of UIV and recycling to the first stage. The reduction of UIV to UIII may be effected by contact with a solid reductant, e.g. Zn or Zn amalgam or by electrolysis. The oxidation of UIII to UIV may be achieved by electrolysis or bubbling an oxidizing gas through the solution. Net transfer of UIV during isotope exchange may be prevented by inclusion of a "salting out agent", e.g. HCl which when added to an aqueous solution of an organic compound causes separation. This agent is removed from the aqueous phase before UIV extraction from the organic phase. Oxidation of UIII during exchange may be prevented by providing an electrically insulating surface throughout the device (except in the oxidizing circuit and reducing circuit electrodes) and by maintaining content of Ni, Co and Cu ions below 1 p.p.m. in aqueous phase. In an alternative, one phase is solid, e.g. UIV on an anionic ion exchange resin or VIII on a cationic resin.

Filed: 1941-07-17
Abstract: 550,025. Control of motors. SMART, A., and ELECTRO-CHEMICAL ENGINEERING CO., Ltd. July 17, 1941, No. 9025. [Class 38 (iii)] Travelling to predetermined limits. A sequence of operations is effected by a plant driven by a motor and a predetermined time elapses between each step in the sequence. A relay CSRC controls jointly the main motor and a control switch motor so that they operate alternately. The relay circuit comprises pairs of switches CS1, US1, CS2, LC1 ... CS9, LC4 of which the switches UC, LC are limit switches, operated in turn as each successive step in the sequence is completed, and the switches CS are operated in sequence by adjustable cams driven in common by the control switch motor CSM. The closure of a limit switch UC1, for example, engages the relay CSRC through the previously closed control switch CS1, whereupon relay contacts CSR open the circuits of forward and reverse contactor coils FR of the main motor DM and close contacts a to start the control motor CSM. The latter, after a predetermined time interval, opens control switch CS1 and closes control switch CS2, whereupon the motor CSM stops and the main motor effects the succeeding step in the sequence of operations, causing eventual closure of limit switch LC1 &c. When the sequence is complete a selected control switch CS7 in series with an open time switch contact TS is closed by the motor CSM. The sequence is restarted after energization of the time switch TSC by a manual switch d in series with an interlock contact D operated by motor CSM. Auxiliary switches BC (controlling the contactors F, R) and A (controlling a magnetic clutch MC) are also actuated by the motor CSM.

[Class 7 (iii)] [See also Group XXIX] The throttle is actuated by a device subject to the suction in the mixing chamber, the suction effect on the device being controlled by a member actuated by the accelerator pedal. An arm 6 on the throttle valve 5 is connected by a link 13 to the rod 11 of a piston 9 movable in a cylinder 8 and loaded by a spring 10. The control member comprises a casing R in which a valve 15 is adapted to be rotated through a spindle 14 by the accelerator pedal. The casing has a pipe c leading to the mixing chamber on the engine side of the throttle 5, a pipe a leading to the cylinder 8 above the piston 9, and pipes e, f, g leading to the cylinder below the piston through the medium of a branch pipe b. The pipes f, g, b are provided with constrictions v, x, z respectively. During idling, the valve 15 is in a position to close pipes e, f and to open pipes g, a, the result being to maintain piston 9 in its lowest position and the throttle valve closed. The constriction x prevents a sudden closing of the throttle and consequent spurting of fuel from the nozzle. When the accelerator pedal is depressed, for part opening of throttle, the valve 15 is in the position shown in Fig. 2, with the pipes e, g, closed, the pipe f open to atmosphere, and the pipe a in communication with the mixing chamber through a constricted part of a bore in valve 15. The result is that the piston 9 is raised through part of its travel and partly opens the throttle valve, the movement being damped by the constriction v. When the accelerator pedal is fully depressed, the valve 15 is moved to a position, Fig. 3, where pipes e, f are open to atmosphere, and pipe a to the mixing chamber without any damping effect and the throttle is fully opened. When the engine is cold, a piston 21 of a device T may be actuated by a thermostat to open a pipe p and partly destroy suction in cylinder 8 and cause the throttle to move forwards its closing position. In a modification, Fig. 5 (not shown), the rod 11 of piston 9 actuates a plunger in an auxiliary cylinder to force air into the float chamber, as the piston rises, and increase the flow of fuel.

Abstract: 269,523. Aktiebolaget Vaporackumulator. April 19, 1926, [Convention date]. Steam regenerative accumulators.-The quantity of water in a regenerative accumulator storing excess steam from a steam supply system is increased when the pressure in the accumulator rises to the admissible mnximum pressure, thus allowing the accumulator to take up further excess steam. A regenerative accumulator S connected to a pipe B supplying steam from a boiler A to power plant T is supplied with additional water through a pipe L2 fitted with a pressure-operated valve V, which is opened when steam supply pressure reaches a certain limit. Hot water is withdrawn from the accumulator for supplying the boiler or for other purposes. Water may be automatically discharged from the accumulator when the level rises to a certain height. The pump P2 in the water supply pipe may be started by the rise in steam pressure and the valve V dispensed with. In a modification, the accumulator is supplied with the excess steam through an overflow valve controlled by the temperature or pressure of the supply steam, and the steam withdrawn is taken to the low pressure parts of the power plant. The water supply to the accumulator is, in the modification, preferably controlled by the pressure in the accumulator. Water supplied through the pipe L2 may pass through a cooling coil in the steam or water space of the accumulator and serve to raise the water level therein only by condensing part of the excess stem supply.
