Title: Improvements in or relating to devices for passing electric signals with time delay
IPC: H03K5/13
Filed: 1953-11-30
Abstract: 782,262. Pulse delaying circuits. GENERAL ELECTRIC CO., Ltd., and IMM, R. C. Nov. 25, 1954 [Nov. 30, 1953], No. 33273/53. Class 40 (6). A pulse delaying circuit comprises a cathodecoupled pair of electric discharge-tubes to the grid of the first of which the input pulse train to be delayed is applied and the anode of the second tube of the pair is connected to a positive supply line via a capacitor. A positive-going pulse train is supplied via a unidirectional conducting device to the anode of the second tube of the pair and a second train having the same pulse repetition frequency as the first but delayed in time with respect to it is applied to the control grid of the second tube of the pair so that upon the occurrence of each pulse of the second train the anode voltage of the second tube is dependent upon the voltage value of the input signal. Fig. 1 shows two stages of a pulse delaying device in which the input pulse train, Fig. 2c, is applied to the control grid of a first tube 2 of a cathode-coupled pair of tubes 2, 3. The input train is a pulse code modulation signal which is divided up into a number of adjacent intervals in each of which there may be a positive-going pulse in dependence upon the modulating signal. A train of positive-going pulses, Fig. 2a, is applied to the anode of a diode 15 and a similar train of pulses, Fig. 2b, but slightly delayed with respect to the first is applied to the control grid of tube 3 of the cathode-coupled pair. In the absence of a positive input signal when a pulse such as 18, Fig. 2a, is applied at point A capacitor 12 is charged to a voltage level 19, Fig. 2d. When the next of the pulses applied to the control grid of tube 3, for example 17, Fig. 2d, occurs, tube 3 conducts and capacitor 12 is discharged to a voltage level 21, Fig. 2d. When, however, a positive-going pulse such as shown at 22, Fig. 2c, is applied at input C tube 2 conducts and due to the current flow in resistor 4 tube 3 is cut off so that pulse 17<SP>1</SP> applied at control grid of tube 3 has no effect on the conductivity of this tube and capacitor 12 remains charged. When the next pair of pulses 18<SP>11</SP> and 17<SP>11</SP> appear the voltage drops to level 21, thus as will be seen at point D a pulse train occurs which after the first pair of pulses 17, 18 is a delayed version of the pulse occurring at the input C. An integrating network 24, 25 is provided between the output of one delay stage comprising tubes 2, 3 and the input of a further similar stage. The voltage on the control grid 26 of tube 23 as shown in Fig. 2e, is clamped by diode 27 to the same level as is the voltage on the grid of tube 2, thus upon the occurrence of pulses 17<SP>1</SP>, 18<SP>1</SP> the voltage on grid 26 is insufficient for the voltage on anode 27 to be raised to its higher value although pulses 17<SP>11</SP>, 18<SP>11</SP> do cause that to occur. The voltage on anode 27, as shown in Fig. 2f, is a delayed version of that occurring at the anode of tube 3.

Title: Production of liquid phenolic condensation products
IPC: C08G8/10
Filed: 1956-11-09
Abstract: Light-coloured, stable, water-dilutable, liquid phenolic condensation products are prepared by heating a monohydric phenol, water, 0.8-3 mols. of formaldehyde and/or a substance which acts as a source thereof for each mol. of monohydric phenol and, as a catalyst, lithium or barium oxide, hydroxide or carbonate at a pH not exceeding 9, with the free formaldehyde content of the reaction mixture is less than 5 per cent by weight, cooling the resulting reaction mixture to below 30 DEG  C., adjusting the pH of the cooled reaction mixture to 6-7.2 with orthophosphoric acid or a substance which in aqueous solution acts as a source thereof, and thereafter removing separated solids from the reaction mixture.  The heating is normally at 30-90 DEG  C., water being removed under reduced pressure.  Phenols specified include phenol, cresols, xylenols, tertiary butyl phenol, phenethyl phenol and mixtures thereof.  There should be sufficient water present to dissolve the phenol(s) and catalyst.  Aldehydes specified are formaldehyde, formalin, paraformaldehyde and mixtures thereof. Specified catalysts are lithium hydroxide monohydrate and barium hydroxide octahydrate.  Sources of orthophosphoric acid include meta-, hypo- and pyrophosphoric acids.  The precipitation proceeds more favourably when the solution contains less than 50 per cent w./w. of the condensation product; to achieve this, water or a water-miscible solvent (e.g. ethanol, isopropanol, butanols with or without small quantities of liquid monocyclic aromatic hydrocarbons such as benzene or xylenes) may be added.  The reaction products are dilutable with large quantities of water and may be used as binders for glass fibres and mineral wools, such as rock wool.

Abstract: 917,583. Circuits employing bi-stable magnetic elements. LUCAS (INDUSTRIES) Ltd., JOSEPH. Oct. 11, 1960 [Oct. 12, 1959], No. 34461/59. Class 40 (9). A self-hold unit includes two ferrite or other square-loop cores F1,F2 each having a control winding L3, L6, an input winding L2, L7, and an output winding L4, L8, the control windings L3, L6 being supplied with Y and X clock pulses respectively and any input signals supplied to the input windings L2, L7 being out of phase with the Y and X pulses respectively so that such input signals produce an output from the cores respectively, and a diode pump circuit operable by the output from the core F1 and arranged after receiving a predetermined plurality (e.g. ten) of output signals therefrom to provide input signals to the input winding L7 on core F2 each time core F1 produces an output, the output core L8 from core F2 providing an input to a winding L1 on the first core to produce an output. Continuous pulsing of the unit is obtained after capacitor C2 is sufficiently charged. The diode pump circuit consists of two capacitors C1, C2 and two diodes D1, D2, capacitor C1 being alternately charged through diode D2 and discharged through diode D1 into larger capacitor C2. When capacitor C2 is sufficiently charged it acts as high-tension source for a transistor T7. This transistor is rendered conductive by the output from winding L5 and, after capacitor C2 is sufficiently charged, each succeeding pulse in winding L1 and/or winding L2 produces a pulse through the transistor T7 and winding L7, the pulses applied to winding L7 being out of phase with the X clock pulses. The transistors all act as switches. They may be replaced by coldcathode tubes. Core F2 has an additional output winding L9. Pulsing continues until the source of power or source of clock pulses is cut off.

Abstract: 988,327. Pulverulent-fuel firing systems. BABCOCK & WILCOX CO. Sept. 28, 1961 [Sept. 30, 1960], No. 34816/61. Heading F4B. In a pulverized fuel firing arrangement for a furnace in which pre-heated primary air is passed through pulverizing means to entrain fuel the primary and secondary air are heated in parallel combustion gas paths and means are provided for controlling the temperature of the primary air by mixing therewith relatively low temperature primary air prior to the entrainment of fuel. Means are also provided for controlling the flow of combustion gas through said air heating means to regulate the temperature of said gas downstream of the heating means. As shown in Fig. 4 four fans 40 supply primary air through pipes 46 to a common duct 41 whence fans 15 supply it to a primary air heater 16 which has a by-pass duet 54. The outlets from the heater 16 and duct 54 lead to a hot air duct 14 and cold air duct 17 respectively which supply a plurality of pulverizers 13 with selected proportions of hot and cold primary air. Secondary air is also supplied by the fans 40 through rotary regenerative heaters 18 having by-pass ducts 42. The primary air/fuel mixture is supplied from the pulverizers 13 to burners 12 at opposite walls of the furnace 10 of a vapour generating, superheating and reheating unit (Fig. 1) and secondary air to a duct 70 enclosing the burners. The primary air heater 16 comprises vertical tubes 31 which receive combustion gases from a plenum chamber 21 through a duct 27. Further ducts 20 (Fig. 3) lead from the chamber 21 in parallel with duct 27 to the rotary regenerative heaters 18, the ducts 20 containing economizer tubing 30. Combustion gases flow downwardly through one half of the tubes 31 in the air heater 16, through a chamber 34 beneath the heater, 'upwardly through the remaining tubes 31 and are discharged through a duct 37. The flow of combustion gas is regulated by means of a damper 36 in the chamber 34 in accordance with the mean of the gas outlet and air inlet temperatures as sensed by thermostats 63 and 61 respectively (Fig. 1). The signals from the thermostats are passed to a relay 62 and a device 64 controlling the damper 34. The proportions of hot and cold primary air supplied to each of the pulverizers 13 from the ducts 14 and 17 respectively are regulated by means of a control device 60 which senses the temperature at the outlet of the pulverizer and positions dampers 56 and 57 accordingly. A total primary air flow control 58 is regulated in accordance with the fuel supply to each pulverizer.

Abstract: 761,570. Electric selective signalling. MULLARD RADIO VALVE CO., Ltd. Oct. 28, 1954 [Dec. 15, 1953], No. 34904/53. Class 40 (1). Digital data recorded by printing or magnetically, but preferably by holes punched in a tape, is translated into analogue form for effecting a control such as programming automatically the temperature of an oven. The record sensing apparatus comprises a sensing element corresponding to each digit position, a parallel combination of electric resistances, each of which is associated with one sensing element and has a value inversely proportional to the respective quantity, a switch in series with each of the resistances and controlled by the respective sensing element in such manner that the resistance is placed in circuit with a common voltage source when the digit position is marked and with a second voltage source when not marked, and a common resistance in series with the parallel combination of resistances, the arrangement being such that a plurality of digit positions sensed, causes a plurality of currents of corresponding values to flow through associated parallel resistances so that the currents are added in the common resistance and the voltage drop across the common resistance provides an indication of the number or data recorded. A paper tape T, Fig. 1, is provided with groups of holes arranged in frames H as shown and representing numerals 1, 2, 3, 4, 10, 20, 30, 40 and 100, 200, 300, 400, as shown. Each digit " position " is provided with a sensing element associated with a switch P1, P2, &c., Fig. 2. The switches when actuated place the respective ones of the parallel resistances R1, R2, &c. in circuit with the common voltage supply +V and so contribute to the current flowing in the common resistance R100. The alternative switch contacts are shown in Fig. 2 as providing an earth connection, but as an alternative arrangement a voltage of one half the voltage supply +V may be employed giving a smaller range of voltage change but still in the same number of steps, i.e. 1000 equal steps. A meter M and resistors R20, R20A, and R21 are provided for setting the voltage V accurately to a standard value by comparison with a standard cell connected between terminals B. The adjustable resistance R20A in series with R20 is for initial adjustment; the other variable resistance R21 alters the meter sensitivity.
