Abstract: 1316605 Semi-conductor devices ENERGY CONVERSION DEVICES Inc 8 May 1970 [16 May 1969] 22367/70 Heading H1K [Also in Division C4] A display screen apparatus (see Division C4) includes electroluminescent material 14 and variable resistance semi-conductor material 13 having a first inherently stable high resistance structural condition and a second inherently stable low resistance condition as defined, the s/c material being reversible between the two conditions by application of energy thereto, to control the material 14 light emission. By "inherently stable" is meant the indefinite persistence, without decay, of the excited condition, on removal of the applied energy, and the EL material exciting voltage, further applied energy being necessary for reversion to the original condition. Layer 13 is preferably continuous. The applied energy for excitation or erasure may be a laser, or photoflash which may involve heat as well as light, electrical energy and for heat radiation or protons or electrons with heat radiation, heated wires or a hot air stream, and spark discharges being also exemplified. Layer 13 is preferably polymeric, and may also be 85% Te; 15% Ge with O and/or S inclusions, Ge 15 A 15 Se 70 ; Ge 15 Te 81 S 2 P 2  or Ge 15 - Te 81 S 2 Sb 2  and Ge 15 Se 81 S 2 P 2  or Ge 15 S 81 S 2 Sb 2 , desired capacitances and resistances in both states being governed by compositions and thicknesses of the laminations. Conversions to low and high R states may be by 1-100 ms. or more and 10 Ásecs. or less pulses. The nature of structural changes are considered producing R, C and E changes for example, the high R state being substantially disordered and generally amorphous. Layer 14 dielectric constant is typically 10<SP>14</SP> to 10<SP>18</SP> #/cm., that of layer 13 being typically less, e.g. 10<SP>5</SP> to 10<SP>7</SP> #/em., disparity being compensated by non-linear γ-# characteristic as in Fig. 7 (not shown). Figs. 4, 5 (not shown), illustrate high and low state equivalent circuits, reactive impedance characteristics of capacitors (30) (32) being as in Fig. 6 (not shown).

Title: Process for the preparation of cationic condensation products
IPC: C08G12/04
Filed: 1956-07-24
Abstract: A process for the preparation of a cationic condensation product comprises condensing together a salt of a monoamine containing a liphophilic residue which contains at least 6 carbon atoms, preferably 12 to 22 carbon atoms in the molecule, dicyandiamide and formaldehyde.  The hydrocarbon residues of the amines may be straight or branched and interrupted by hetero atoms or groups or may carry substituents, e.g. hydroxyl or amino groups.  Specified are octyl, dioctyl, dodecyl, octadecyl, oleyl, cyclohexyl, methylcyclohexyl and octylcyclohexylamines and also mixtures of preferably primary amines produced from fatty acid mixtures from natural fats or hydrocarbon fractions.  A molar ratio of dicyandiamide to formaldehyde of 1:0.5 to 1:6 is suitable, with part of the dicyandiamide, suitably 0.1 to 0.7 mol., replaced by an equimolecular amount of the amine.  Reaction may be effected under pressure.  If effected in organic solvents, e.g. methanol, ethanol, butanol, ethylhexanol, benzyl alcohol, methylcyclohexanol or tetrahydrofurfuryl alcohol, part of the alcohol takes part in the condensation, to give products soluble not only in water but also in organic compounds such as alcohols, chlorinated hydrocarbons, polyglycols, fatty alcohols, fatty acids and (in the presence of fatty acids) in fatty oils.  The products can be hardened using catalysts such as acids or ammonium salts or insolubilized with anionic compounds or resins, or with, e.g., water-soluble salts of polymeric inorganic acids such as silicates and phosphates.  The products, or their aqueous emulsions in fatty alcohols, fatty acids or fatty oils can be used in the treatment of textiles or glass fibres, paper, wood or porous materials or in the paint and lacquer industry.  In examples, condensation products are prepared by reacting together dicyandiamide, formalin or paraformaldehyde and the hydrochlorides of mixed primary aliphatic amines derived from (1), (3) and (4) coconut oil acid; (2) tallow fatty acid, methanol and butanol, respectively, being also present in the mixture of Examples (3) and (4).

Title: Improvements in or relating to register-senders for use in automatic telephone systems
Inventor: KEATING JOHN HENRY
IPC: H04Q3/00
Filed: 1962-06-14
Abstract: 971,177. Automatic telephone exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. May 21, 1963 [June 14, 1962], No. 22856/62. Heading H4K. In an STD system, a register-sender which records a number of exchange code digits is arranged in various circumstances to suppress the retransmission of the first digit, the first two or more digits, or even all the digits under the control of a common circuit conveniently termed a translator which monitors the availability of the routes outgoing from the exchange where the register-sender is located. Fig. 1 shows two primary areas PA1, PA2 of an STD system having primary, secondary and tertiary switching centres P, S, T. The " backbone " route between end exchanges E(A), E(B) is through both switching centres P(A), P(B), but it may be that the trunking arrangements provide a number of shorter routes such as those indicated. Each tertiary and secondary centre is equipped with an incoming relay set TRS, Fig. 2, and routing selectors 1RS, 2RS together with a register and common translator. At the tertiary centre T(A), for example, the P digit is received first in TRS and is transferred to the register which then takes the later code digits S, T, E and the numericals. If there are more than 10 primary areas, PA and PB digits replace the P digit. After the S digit, the recorded information is referred to the translator, and, if it is sufficient, instructions are returned to the register for the control of 1RS, 2RS,inter-train pauses between the retransmitted digits, absorption of any or all of the code digits and the tariff. The tariff indication is transferred to TRS. If, however, no instructions are forthcoming the translator is released and is reseized after the T digit is received, or, if necessary, after the E digit. The equipment at the secondary centre S(A), for example, is somewhat simplified, since no provision is required for recording the numericals nor the tariff. The circuits of the register-sender are described, Figs. 3 . . . 6 (not shown).

Abstract: 1,192,632. Air conditioning systems. CONNOR ENG. CORP. 17 May, 1967 [2 June, 1966; 20 March, 1967], No. 22971/67. Heading F4V. A plenum chamber 1 in an air conditioning system is supplied with air through an inlet 8 controlled by a damper 26 and has a valve or damper 5 controlling an outlet, the valve 5 being controlled by a pneumatic thermostat 2 in the room to be air conditioned. If the valve 5 is partly closed by the action of the thermostat pressure builds up in the plenum and this pressure increase is sensed by a pressure regulator 10 which via an on/off switch 12 causes the inlet damper 26 to partly close. An air line 14 (at 15 p.s.i.) supplies the force to adjust the dampers, the thermostat being of the leakage type in which the amount of air leakage is dependent upon the temperature. A heater 17 is controlled by a valve 16 also dependent upon the thermostat 2. A grille may be fitted over the outlet 5. The heater may operate by hot water or by electricity . In a modification the valve 5 may have two series of outlets, one series operating automatically and the other series manually.

Title: Improvements in or relating to circuits comprising thermal switch time-delay devices
IPC: H01H43/30
Filed: 1956-07-25
Abstract: 810,747. Switching systems. SOC. D'ELECTRICITE MORS. July 25, 1956 [July 28, 1955], No. 23044/56. Class 38 (4). [Also in Group XXXVII] A circuit arrangement for introducing a time delay into the operation of a component comprises a bi-metal thermal switch, the time delay period comprising both the heating time and the cooling time of the bi-metal element, the cooling time being substantially longer than the heating time. In the circuit arrangement shown in Fig. 3 the energization of relay 23 and operation of its associated contact 30 are the operation to be delayed. Connection of terminals 21, 22 to a source of potential first causes a current to flow in a heating winding 6 of a bimetal thermal switch 16 the circuit being 21, 18, 32, 31, 8, 6, 7, 22. After the heating time has elapsed, the bi-metal element 1 moves to make contact with contact 5. A relay 20 now becomes energized-through a circuit 21, 18, 5, I, 17, 24, 25, 7, 22-thereby moving the contact 27 from contact 31, 26. This movement breaks the circuit to the heating winding 6, causing the bimetal element to cool, and establishes a selfmaintaining circuit for the relay 20. When, now, the bi-metal element 1 has cooled sufficientlv for the element to once more make contact with the contact 4 a circuit is established to allow the relay 23 to be energized, the circuit being 21, 18, 32, 26, 24, 17, 1, 4, 19, 29, 28, 25, 7, 22. Thus the energization of the relay 23 has been delayed by a time equal to the heating time plus the cooling time of the bi-metal element 1. The circuit can be modified to increase the delay time by the addition of further relays. The initiation of the operational sequence can be made by the momentary operation of a pulse source which operates a self-maintaining relay. Specification 612,656 is referred to.
