Title: High speed recorders
IPC: G03G15/32
Filed: 1961-07-26
Abstract: 999,043. Electrophotographic and photographic recording. RANK-XEROX Ltd. (Haloid Xerox Inc.). July 26, 1961, No. 27138/61. Headings G2A and G2H. A high speed recorder records information represented by electrical signals on a light sensitive member. The signals are supplied to a cathode ray tube 10, e.g. a "Charactron" (Registered Trade Mark) from an electronic computer, data processor, or a magnetic data storage unit. An image in the form of alpha-numeric characters on the face 18 of the tube 10 is optically projected on to a endless belt, e.g. having a conductive backing 21 and a photoconductive layer 20. Alternatively, the light sensitive member may be a silver halide microfilm or a diazo material. The photoconductive layer 20 may be anthracene, sulphur, or vitreous selenium. The belt passes around rollers 23, 24 and 25, the roller 23 being driven by a motor 26 mechanically coupled to a tachometer 42. The belt is uniformly electrostatically charged by electrode 28 before exposure; the latent electrostatic image formed is developed by cascade apparatus 29. The developed image is transferred to a paper web 30 by an electrode 31 which applies a charge to the web of polarity opposite to the powder image. The motor 26 is under the control of a servomotor control 37. When a line advance signal is received, the electron beam in cathode ray tube is deflected downwardly by a deflection plate 33 or a deflection coil, such that the starting point of the line is deflected to the axis XA, Fig. 2. The display of characters along the line Z occurs in synchronism with the movement of the endless belt. The plate 33, Fig. 1, is connected to an amplifier 39 connected to the de-coding resistive network 35 of a reversible binary counter 35 which applies error signals to a position detector 36 connected to servomotor control 37. The tachometer 42 produces a voltage proportional to the speed of the motor which is converted into pulses by an analogue to digital converter 43, such pulses being fed to the binary counter 35. For repetitively printing the same format the cathode ray tube 10 may be provided with horizontal deflection plates 49, Fig. 7, while a control system 50, connected to the plates 33 and 49, is fed by a horizontal and vertical position memory unit 48. Instead of employing tachometer 42, the endless belt may have a variable density track 44, Fig. 6 (not shown) co-operating with a light source and photo-cell to produce electric pulses fed to the converter 43. Alternatively the belt may have magnetic marks detected by a pick-up head to produce the pulses.

Patent GB-228600-A (GB)
Title: Improvements relating to the storing and counting of electrical impulses
IPC: H04M3/36
Filed: 1923-10-31
Abstract: 228,600. Francis, F. W., and Cruickshank, W. Oct. 31, 1923. Metering.-An arrangement for counting events which occur at different locations comprises means at each location whereby each event changes the physical condition of a storage device, the counting apparatus being brought successively in cycles under the influence of the various storage devices to count the events and restore the storage devices to their normal condition. As shown applied to the totalization of the calls made on a telephone exchange, the calls are made to close an electrical circuit whereby a condenser is charged, a highspeed rotary distributor being arranged to connect the condensers successively with a counting device which is operated for each condenser discharge. When the operator depresses her key to operate the position meter PM, two relays R<1>, R<2> in the meter lamp circuit are energized and relay R' opens contact 11 so that relay R<2> is immediately de-energized. In energizing, relay R<2> connects a condenser C with the negative pole of a battery, and on the de-energization of the relay R<2> the charged condenser is connected by contact 14 with an insulated segment 13 of a rotary distributor RD. Each segment of the distributor is connected with a relay device and condenser such as R<1>, R<2>, C for each operator's position, and the rotating brush 15 discharges the condensers successively through a polarized relay PR shunted by a condenser C<1> to increase the speed of discharge. The armature of the relay PR is thus rocked once for each discharge, and operates a units counting device ID so that the wheel D, which may have 100 teeth, is moved through one tooth-space. Once in every revolution of the wheel D a contact arm 18 energizes the left-hand winding of a double-wound relay DR, thus closing a contact 19 which energizes the right-hand winding of the relay and operates a hundreds counting device M. When the armature of this counting device has completed its movement it closes a contact 20 to short-circuit the right-hand winding of the relay DR and open the contact 19. The speed of the rotating brush 15 is arranged so that only one depression of any one operator's key can take place between successive connections of the brush with the segment for that operator's position. Relays may be used instead of condensers as storage devices.

Title: Improvements in viscometric apparatus
Inventor: FORD JOSEPH MANNING
IPC: G01N11/08
Filed: 1953-10-06
Abstract: 744,712. Viscosimeters. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 26, 1954 [Oct. 6, 1953], No. 27376/53. Class 106 (2). In a constant flow viscosimeter wherein the flow is regulated by a cylindrical piston reducing valve movable axially in opposition to a spring relative to a co-operating housing means are provided for causing relative rotation between the valve and its housing to avoid friction losses. The valve 3 movable axially against a spring 4 in a housing 2 controls the fluid flow from inlets 6 to ports 7 whence the fluid passes to an annulus 8 leading to capillary channels 9 opening into a space 10 from which the liquid emerges through a sharp-edged orifice 12. With constant flow so attained, the pressure in space 10 is constant and hence the pressure at the inlet 6 is a measure of the viscosity. The fluid emerging from the orifice 12 impinges on and rotates a paddle wheel 15 whose spindle 16 has at its upper end a gear 18 co-operating with a gear 19 on a bearing 20 for the end of the spring 4. A rotational drive is thereby imparted to the spring and thence to the piston 3 and if desired to an indicator 22. In another embodiment the orifice 12 is mounted tangentially on the end of an arm attached to the end of the piston which is rotated directly by the reaction of the jet of emergent fluid.

Title: Fractional distillation of a mixture of polymerisable compounds
Inventor: BORTOLINI PAOLO
IPC: B01D3/34
Filed: 1959-08-12
Abstract: <PICT:0925086/III/1> In order to prevent thermal decomposition or polymerization in the fractional distillation of a mixture of organic compounds containing one or more components which undergo chemical change at high temperature, the heat required for the fractionating column is obtained by spraying the liquid mixture, withdrawn from the base of the column, into a stream of hot, relatively p noncondensable gas (e.g. ammonia, methane air or hydrogen); the vapour-saturated gas is then allowed to flow upward through the column which is supplied, at the top, with a liquid reflux stream comprising the more volatile component of the mixture being separated.  The process is particularly suitable for the separation of methylvinylpyridine from methylethylpyridine.  The mixture of MVP and MEP is introduced through line A into fractionating column 3 and, due to fractionation in the presence of the rising gas stream, concentrated MVP collects in the base of the column.  Some of this MVP is withdrawn through line 13 as product, and the remainder is sprayed, in vaporizer 2, into a stream of ammonia gas which has been previously raised to 200 DEG C. in heater 1.  The saturated gas leaving the vaporizer is introduced into the lower section of the column, the temperature of this gas being regulated at 100 DEG C. by temperature-sensitive device 10 which is connected, via pneumatic lines and regulator 11, to by-pass valve 1a.  The gas leaving the top of the column is saturated with MEP.  This gas is first passed through condenser 4 and then through condenser 5 until it has cooled to 5 DEG C.  Some of the condensed MEP is recycled to column 3 as reflux, and the remainder is withdrawn through line 12.  The cold ammonia gas leaving condenser 5 flows to compressor 7, and then back to heater 1.  About 3% of the circulating gas is, however, withdrawn between compressor 7 and heater 1; and this portion is compressed to about 9 atm. by compressor 8.  The compressed ammonia is liquefied in condenser 9, and the liquid ammonia is injected into the ammonia from condenser 5.  The gas, withdrawn from separator 51, is used as cooling-medium in condenser 5.
