Title: Improvements in or relating to apparatus for stacking letters and like articles
Inventor: WILLIAMS JAMES
IPC: B65H29/14
Filed: 1950-07-05
Abstract: 712,608. Sheet delivery apparatus. POSTMASTER GENERAL. June 26, 1951 [July 5, 1950], No. 16845/50. Class 100 (1) In apparatus for stacking letters and like articles, e.g. leaving a stamp-cancelling or sorting machine, the letters to be stacked are passed between stack-feeding rollers 28, 29 rotating at a peripheral speed which is less than the speed at which the letters travel towards the stack-feeding rollers and the letters are thereby presented for engagement by projecting portions 35a of at least one rotating letter-stacking member 35 which rotates about an upwardly extending axis 36 and co-operates with an abutment or stop member 9 and a stack-supporting member 11 to cause the letters to form a stack. The letters, travelling along a conveyer 37 are deflected in selected destination boxes, of which there may be a plurality, Figs. 1 and 2 (not shown), by electromagnetically operated vanes 38 so that the letters are fed by diverter rollers 23 into a guideway 18 formed by guides 17, 19, and 32. The guides 32 consist of vertical grid-like structures in order to avoid wind resistance between them and the letters and carry the rollers 29 which co-operate with fixed rollers 28. The guides 32 are pivoted about a vertical axis 23 so that thick letters may pass between the stack feeding rollers 28, 29. The rollers 28, 29 are driven at a slower peripheral speed than the conveyer so that the letters may overlap one another when fed into the destination box. The rotating stacking member 35 may comprise a series of rotating polygonal discs, e.g. hexagons, or may be an elongated tubular shape polygon. The destination boxes comprise abutments 9 and a side wall 5 and an inclined stack supporting member 11. The member 11 is provided with a handle 22 and is pivoted about an axis in the base of the apparatus on which it may slide horizontally. The member 11 may be rotated about its axis clear of the letters when it is desired to remove them, Fig. 1 (not shown).

Title: Improvements in or relating to devices for suppressing unwanted electrical signals
Filed: 1955-06-13
Abstract: 801,968. Classifying random impulses. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 13, 1955 [June 16, 1954], No. 16946/55. Class 37. [Also in Groups XL (b) and XL (c)] To eliminate escape pulses from the output of a radiation detector, main pulses are reversed in polarity, amplitude adjusted, and combined with the escape pulses. As shown, X-rays from a source 15 fall on an object 11 under examination, secondary radiation being received on a detector of known type with electrodes constituted by a central rod and an outer cylinder. The output pulses produced by the detector are fed through an amplifier 17 to a pulse, analyser 19 of known type which performs a scanning action feeding pulses of selected amplitudes in turn to an integrating circuit 21. Thus the output of the integrator is first a signal representative of the pulse rate of the main pulses followed in time by a signal representative of the escape rate. The main pulses are then applied to the screen grid of a mixer valve 23 and the output at the triode is applied to a recorder 37 synchronized with the pulse analyser. The main pulses are also recorded on a magnetic tape 42 synchronized with the pulse analyser after being fed through a recording modulation circuit 46 in which any necessary A.C. biasing may be preferred. The signal is fed by head 47 after a delay representative of the time taken by the pulse analyser to progress to the escape pulses and then demodulated to remove the A.C. bias and amplitude adjusted at 50 so that when it is fed to the control grid of valve 23 its arrival coincides with the application to the screen grid of the escape pulse which is thereby cancelled. The memory device may comprise a delay line or signal reflecting line having inherent phase reversal or may comprise a device which produces a delayed pulse in response to an incident one. In the arrangement of Fig. 3, a multi-channel pulse height analyser is used comprising individual channels 1-10, each passing pulses of different energy levels. Part of the output from the channel 10 as tapped by potentiometer 72 is phase inverted and combined with the output of channel 5 at which the escape pulses appear. Thus the escape peak signal is cancelled out. A new unidirectional signal conducting device 75 may be included in the connection between the channels.

Filed: 1935-06-14
Abstract: o-Hydroxyazo dyestuffs are manufactured by coupling o-hydroxydiazo compounds, e.g. of the benzene and naphthalene series, in alkaline medium with derivatives of 2-amino-7-naphthol in which one hydrogen atom of the amino group is substituted by a hydrocarbon radicle or a substituted hydrocarbon radicle, e.g. alkyl, hydroxyalkyl, cyclohexyl, aryl or aralkyl, and in which the naphthalene nucleus may be further substituted, e.g. by halogen or carboxylic or sulphonic acid groups, the components being so selected that at least one sulphonic acid group is present in the dyestuff molecule.  The products yield dark violet, blue to black after-chromed shades on wool, whilst some of them may be dyed by the single bath chroming process.  They may also be converted by treatment with metal salts into complex metal compounds, which dye wool and silk.  Examples describe the production of the following dyestuffs: (1) 4 - nitro - 2 - aminophenol - 6 - sulphonic acid --> 2 - phenylamino-- 7 - naphthol; (2) 4 - chloro - 2 - aminophenol - 6 - sulphonic acid --> 2-phenylamino-7-naphthol; the product may be converted into its complex chromium compound; (3) 5-nitro-2-aminophenol --> 2 - phenylamino - 7 - naphthol - 6-sulphonic acid; (4) 4 : 6-dinitro-2-aminophenol --> 2 - phenylamino - 7 - naphthol - 6 - sulphonic acid; (5) 5-nitro-2-aminophenol --> 2 - hydroxyethylamino - 7 - naphthol - 6-sulphonic acid; the product may be converted into its complex chromium compound.

Title: Improvements in or relating to frequency dividing circuits
IPC: H03K3/06
Filed: 1943-10-21
Abstract: 568,556. Valve generating circuits. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Oct. 21, 1943, No. 17375. Convention date, Oct. 22, 1942. [Class 40 (v)] The invention relates to frequency dividing circuits comprising a multi-vibrator to which the frequency to be divided is fed through a buffer stage. The cathodes of the multivibrator pair are connected together and grounded through a resistance, while the anode of one valve is connected through a resistance to a direct-current ,source and through a coupling condenser to the grid of the other valve. The buffer stage whose output is fed to the control grid of one of the multi-vibrator valves has its cathode positively biassed relatively to ground, while its control grid is connected both to the anode of one of the multivibrator valves and to means for impressing on it a voltage which increases with time relatively to ground. In this way only the first valve of the multi-vibrator is conductive during the charging period while the gain in the buffer stage, and thus the amplitude of the negative pulses fed to the conductive valve in the multi-vibrator, increases rapidly at the point at which the valves in the multi-vibrator change over in conductivity. In this way, division of frequency in a ratio much greater than 10 to 1 is achieved with reliable operation. The Figure shows a multi-vibrator 1, 2 with the common cathode resistance 9 from which the output is derived, while the ratio of division is determined by the negative bias applied from the potentiometer 12 to the grid of the valve 2 and the time constant of the condenser 31 charged over resistance 29 and discharged by valve 2. The input is applied to terminals 27 of the buffer stage 16, from the output of which negative pulses are fed over a condenser 22 to the multi-vibrator valve 1. The point at which the gain of the buffer stage 16 increases is determined by the bias applied to the cathode from potentiometer 28.

Title: Improvements in or relating to apparatus for effecting intimate and thorough exchange between a gas and a liquid
IPC: B01D3/14
Filed: 1944-09-13
Abstract: <PICT:0624605/III/1> <PICT:0624605/III/2> An apparatus for effecting intimate contact between a liquid and a gas or vapour, e.g. a dephlegmator, comprises a housing containing a plurality of superposed liquid-cascade sections disposed at right angles to each other, each section being made up of staggered troughs associated with vertical baffles, the upper ends of which are perforated, whereby upwardly flowing streams of gas are directed horizontally into staggered streams of liquid to produce a series of turbulently and rapidly - moving intimate mixtures of gas and liquid, and these mixtures are impelled against the baffles.  A series of horizontal cascade sections A, B (Fig. 1) disposed at right angles to each other are mounted in housing 15.  Each section comprises staggered troughs 31, baffles 123, the upper ends of which are perforated, and a box 37 with open ends.  Each section has associated with it two seal pans 36 into which liquid, from the box of the section above, is guided by aprons 38.  The liquid flows over the lips 35 of the seal pans towards the uppermost troughs of the section, but, as it falls, some of it is entrained by transverse streams of vapour; and the resulting intimate mixtures strike the lower, non-perforated portions of the corresponding baffles 123.  The mixture is diverted up each baffle to the perforated portion thereof.  The liquid passes through the perforations and flows down the back of the baffle to the next lower trough where it is again contacted and entrained by a transverse vapour stream.  The liquid flows down the backs of the two lowest baffles into box 37.  The fractionation of hydrocarbons and of alcohols is referred to.  The Specification as open to inspection under Sect. 91 describes modified devices such as that shown in Fig. 2 (Cancelled), wherein mixtures of liquid and vapour strike horizontal, perforated baffles 23 which support Raschig rings 26.

Abstract: 419,760. Washing granular materials. GREAVES, C., Burley Lane, Quarndon, near Derby. June 20, 1933, No. 17500. [Class 82 (ii).] The heavier material is discharged from the washing bed of a jig by means of a conveyer having spiral or scraper blades which move the material over a surface communicating directly with the washing bed to a discharge point, the conveyer being controlled by the movements of a float which rests on the heavier material on the bed and on rising above a predetermined level connects the conveyer with a source of power by means of any mechanical or electrical device. In the form shown in Fig. 1 a spiral conveyer J works in a trough A communicating directly through the passage G with the washing bed B, the heavier materials being carried along the trough A to the discharge point H. The trough and conveyer may decrease in diameter near the discharge end in order to prevent discharge of heavier material when the conveyer is at rest. Fig. 3 shows a scraper conveyer mounted on a vertical axis F and comprising a rotor J carrying inclined scraper blades J1 which move the material over a surface A communicating directly with the washing bed B to the central discharge H. To prevent clogging fixed projections J2 may be arranged on the surface A. Fig. 4 shows two arrangements of the scraper blades J1. The conveyer in each case is controlled by the movements of a float E. According to the Provisional Specification the form shown in Fig. 3 may be modified by fixing the surface A to the axis F and providing a fixed scraper to cause the passage of the material over the surface to the discharge point.
