[Also in Divisions F1 and G1] Fluid pressure control of brakes (Fig. 1).-The output shaft 15 of an hydraulic motor (see Division F1) is prevented from moving when the motor is inoperative by a brake V comprising movable and fixed discs urged together by a spring 24. Release of the brake is effected by supplying pressurized liquid to a connection 26, thereby to move a piston 25 to the right and cause compression of the spring 24 by a member 23. Liquid is supplied to the connection 26 by a hand or power operated pump.  Hydrostatic transmission (Fig. 2).-The hydraulic motor 40 has servo control of its position and speed. During speed control the output from a tachogenerator 30 driven by the motor is compared with the output from a speed control potentiometer 50, the resulting output being fed to an amplifier 47 supplying a torque motor 48. The motor 48 adjusts the output of a pump 41 feeding the motor 40, thereby to obtain the desired speed. Switches and a contactor 44 are moved to positions P o  when position control is required. Filters 46<SP>1</SP>, 46<SP>11</SP> and a combined amplifier and demodulator 45 are provided in the amplifier circuit.

Abstract: 1427119 AFC Systems BURROUGHS CORP 28 June 1974 [27 July 1973] 28745/74 Heading H3A A clock and sector mark signal generator for use with a rotating storage medium 11 comprises, a device 15, 19 for generating a onceper-revolution signal from the medium 11, a clock signal generator 35, a first device 39 for dividing the clock signals by a selectable factor to generate sector mark signals, a second device 43 for dividing the latter signals, a frequency comparator 23 responsive to the incoming and divided clock signals to apply a control signal to the clock generator 35. Binary coded data stored on concentric tracks on the rotating storage medium is arranged into sections of track called sectors. Clock pulses and sector mark signals associated with each sector must be generated for the writing in or for the retrieval of the coded data. Input signals from the transducer are applied to the frequency comparator 23 as well as to variable modulo counters 39, 43 for periodically resetting them. Each of the counters 39, 43 generates an output signal only when the input pulses exceed by one bit the modulo of the counter if it is not already reset by an input pulse. The comparator 23 produces a binary output which is integrated at 27 to sweep the oscillator 35 in an upward or downward direction until phase lock occurs. The integrator 27 includes a switching arrangement (Fig. 2, not shown) for altering the time constant of the integrating filter when the compared initial frequency difference is large.

Title: Improvements relating to the purification of lubricating oils
IPC: C10G25/06
Filed: 1948-11-08
Abstract: A process, preferably continuous, for purifying lubricating oils by adsorbents such as silica gel in the presence of a paraffinic solvent, comprises mixing the adsorbent with the minimum amount of solvent to form a slurry, contacting it with the lubricating oil, and thereafter washing the adsorbent with an additional quantity of solvent and returning at least part of the desorbed constituents to the initial contact <PICT:0668836/III/1> ing step.  In examples, from 220 to 660 per cent of silica gel calculated on the lubricat-oil to be treated and from 420 to 1200 per cent of solvent such as normal pentane, hexane or heptane, or an aromatic-free petroleum fraction within the gasoline boiling range, are employed, and the liquid to solid ratio for the initial contacting step is from 1.0 to 1.5 cc liquid per gram of adsorbent.  Fig. 2 shows an apparatus with a stripping zone 19 connected to the purifying tower 10.  The oil to be treated enters at 16, and is carried upwards by the paraffinic solvent introduced at 21 and meets a slurry of silica gel and paraffinic solvent descending from the hopper 11.  The purified oil emerges at 23 while the silica gel, washed free from oil by the solvent in the bottom portion of the tower, is carried by a gas current introduced at 14 to a regenerator zone 12 and then to the hopper 11.  A portion of the mixed materials flows from the middle of the tower through a pipe 18 to a stripping zone 19 from which solvent recirculates through a pipe 20 to the bottom of the tower while oil recirculates through a pipe 22 to the middle of the tower. Fresh silica gel and fresh solvent are introduced through pipes 24 and 17 respectively.  In a simplified form, the stripper 19 is dispensed with.  In a further modification, the single tower is replaced by two towers, in one of which the oil is treated with silica gel and in the other the silica gel is washed by solvent.

Title: Improvements in or relating to television or like systems
IPC: H04N5/272
Filed: 1947-11-06
Abstract: 638,937. Television. CINEMA-TELEVISION, Ltd., and JESTY, L. C. Nov. 6, 1947, No. 29593. [Class 40 (iii)] In a system in which signals derived by scanning a background scene are periodically replaced by those derived by scanning a foreground scene to produce at a receiver the appearance of performers located against a background other than that before which they are in fact located, the foreground and background are illuminated by light of different colours. In Fig. 1, the performers 1 appear before a semi-transparent black backcloth 2 illuminated at the rear by blue or ultra-violet lamps 3 and are themselves illuminated by lamps 4 giving yellow or white light from which the blue or ultra-violet components have been eliminated. One form of scanning apparatus A comprises a television camera 5 in front of which is rotated a two colour filter disc 6 having filters so chosen that signals due to the performers alone and the backcloth alone appear sequentially in the camera output. The signals, applied to circuit A, Fig. 2, are separated in a synchronous blanking generator 10, the performer signals passing to a film recorder 14, and the backcloth signals to a limiter and phase reverser 12. The signals from 12 feed a blanking device 15 which receives over line 16 the picture signals representative of the desired background into which the performers are to be inserted. Device 15 blanks out the background signals over the portions corresponding to the positions of the performers and the resultant signals pass by way of 17 to the film recorder where the performer signals and the partially blanked background signals are recorded successively in pairs on single frames of the film. The background signals can be derived by a direct pick-up camera or telecine film scanner. An alternative scanner B employs two cameras 7 and 8 at right angles and arranged to receive light by way of an optical system formed of a dichroic mirror 9, the arrangement being such that 7 receives light from the performers only and 8, from the backcloth only. In this case the signals appear simultaneously in the camera outputs and are applied to circuit B of Fig. 2, the performer signals passing to the film recorder 21 over line 22 and the backcloth signals to a blanking device 20 by way of line 18 and limiter and phase reverser 19. Device 20 operates in the same manner as device 15 to blank out the background signals received from line 23. Recorder 21 records the performer and background signals simultaneously on each frame of the film. By a suitable combination of colour separation filters with an ultra-violet filter, system A may be applied to a colour-picture system. Infra-red light may be used in place of ultra-violet. Specifications 472,762 and 489,717 are referred to.

Abstract: 635,171. Cutting strips of fibro-cement into lengths. MAGNANI, A. Nov. 6, 1947, No. 29610. Convention date, Dec. 24, 1940. [Class 87 (ii)] A plain or corrugated continuous strip 2 of fibrocement has its edges trimmed by rotary knives 3, 4 and is then cut-into sheets 8 by a rotary cutter 5. Each sheet is received on a table 9 to which suction may be applied to hold it on the table. The table is then tilted over, the suction cut off, and the sheet allowed to fall onto a track. The cutting table 1 and the table 9 may both have compressed air supplied to their surfaces to facilitate the movement of the sheets over the tables. The tables may be inclined slightly in the direction of travel of the strip. The rotary cutter 5 is reciprocated across the strip at such an angle that the strip is cut squarely. The cutter may be lifted above the strip by a rack 10, during its return stroke. The movements of the cutter are controlled by a wheel 12 which has electric contacts on its periphery, and is rotated by the advancing strip. When forming corrugated sheets the two tables may be corrugated and the cutter may work in a groove in the cutting table.
