Abstract: 1,210,089. Colour television tubes. TOKYO SHIBAURA ELECTRIC CO. Ltd. 22 Dec., 1967 [27 Dec., 1966; 23 Jan., 1967], No.58497/67. Heading H1D. A colour television tube comprises an electron gun 8, Fig. 1, the beam from which is scanned over a secondary electron emitting screen 7 which emits electrons which are controlled by a colour switching grid 4 and directed towards a fluorescent screen 3 in the form of strips of different coloured phosphors. Since the colour switching grid 4 is acting on slow electrons it requires low switching voltages; for example the primary beam from gun 8 may be accelerated to 4KV, the grid 4 may be 240 volts positive with respect to the secondary emitting cathode 7, the screen 3 may be 12KV positive with respect to the cathode, and the colour switching voltage may be 18V. The cathode 7 may comprise an aluminium foil 6 having a thickness of 500 .U., and a secondary emitting layer 5 of the same thickness comprising lithium fluoride. The switching voltage may be reduced by placing the colour switching grid in contact with the secondary-emitting layer, Figs. 3 and 4 (not shown). In one example of a combined colour switching grid and secondary emitting cathode (Fig. 5, not shown, insulating layers (21) of calcium fluoride are deposited on the sides of the grid wires (20) facing the electron gun; an insulating film (22) of aluminium oxide is formed over the insulating layers and is coated on one side with secondary emissive material (LiF) and on the other side with a metallic film (22). In another construction, Fig. 6 (not shown), wires (31) coated with insulation (32) are coated with metal on one side to form the colour switching grid; the other side adjoins a secondary emitting layer (36) on a metal film (35) deposited on a metal mesh (34). A platinum layer 10 A.U. thick may be provided on the back plate of the secondaryemitting electrode to improve the secondary emission ratio by improving its conductivity.

Abstract: 1447897 Digital transmission; distributors INTERNATIONAL BUSINESS MACHINES CORP 19 Dec 1973 [26 Dec 1972] 58877/73 Heading H4P A digital signal L1, Fig. 1, is shifted through a shift register 102 to a preselected output line A, B, C &c. A logic control circuit 2 marks the stage associated with the selected output, prior to operation of a gate 104 which then passes L1. A plurality of registers makes up a planar array (Fig. 5, not shown) or a three dimensional array (Figs. 6-8, not shown) for data switching. Initially the address of the selected stage is set up in a register (201, Fig. 1A, not shown) of the control circuit 2. Marking pulses M pass through a gate 105, Fig. 1 to cause the "set" state to be stepped along the shift register stages 106-1 &c. and these pulses M also cause (via gate 228 bi-stable 220 gate 221, Fig. 1A) clock pulses C1 to be counted (at 204) until the comparator (203) detects identity with the said address signal (in register 201). The comparator output now causes: the count to stop (228 blocked); a signal HM to go high and lock the "set" state of the selected stage (detailed in Fig. 3, not shown) by blocking one gate (109) and enabling a regenerative feedback gate (108); and the same signal HM to enable the gate 104 Fig. 1 which then passes the input digital signal L1 from a bi-stable 103 to the shift register input 102e. Clock pulses SC step this digital signal through the stages until the selected one is reached whereupon it appears at the output (say B) because the output gate (115) is enabled by the regenerative feedback gate (108). In order to sample the input signal L1 at a time providing the highest probablity of accuracy, the input bi-stable 103 is clocked by a pulse SA whose timing is determined (in Fig. 1A by circuitry including gates 207, 208, 209, &c.) from the mean bit transmission rate. An elaboration of the logic circuit (Fig. 1A, not shown) is given (Figs. 9A, 9B, 9C, not shown) for controlling the three dimensional switching array of Figs. 6 to 8. Two way operation is said to be possible.

Abstract: 1462171 Polymer foils NETHERLANDS APPLIED SCIENTIFIC RESEARCH FOR INDUSTRY TRADE & COMMERCE 19 Dec 1973 [21 Dec 1972] 59086/72 Heading C3A [Also in Division B1] Thin polymer foils for use in a dynamic membrane are made by an interfacial polymerization process wherein one polymer-forming reactant is contained in a non-aqueous liquid phase which is miscible with water and has a boiling point below that of water and the other reactant is dispersed in an aqueous phase in which the non-aqueous phase is dispersed, the polymer being formed at the interface and encapsulating the non-aqueous phase and the dispersion then being heated to a temperature between the boiling points of the non-aqueous and aqueous phases to rupture the encapsulating polymer and evaporate the non-aqueous phase forming an aqueous dispersion of thin polymer foils. Before or after the heating step the unruptured or ruptured foils may be filtered, washed and redispersed in water. At least 70% of the foils desirably have dimensions in each of two perpendicular directions in the plane of the foil between 0À1, more preferably 1À0 microns and 1 mm. and more than 10 times that in the direction perpendicular to the plane of the foil. Suitable reactants for preparing a variety of polymer types are tabulated. Preferably the functional group of the reactant in the aqueous phase is -NH 2 , or -CONHNH 2  and of that in the non-aqueous phase is -COCl, -NHCOCl, -NCO or -OCOCl or the reactant is phosgene, and at least one of the reactants contains 1 or 2 aromatic rings with no more than 2 substituents preferably non-ionic. Dynamic membranes may be formed from the foils by dispersing them in the liquid on one side of a microporous structure and applying pressure so that they are deposited in the pores. In specific examples polymer foils formed by the interfacial polymerization of aqueous diaminoethane and isophthaloyl chloride in CCl 4  or of aqueous 3,3<SP>1</SP>-diaminobenzidine and terephthaloyl chloride in hexane are deposited in the pores of a filter made from blended cellulose esters with average pore size 0À22 microns in a reverse osmosis apparatus.

Title: Use by compressed air of waste heat in internal combustion engines
IPC: F02B33/34
Filed: 1971-12-21
Abstract: 1373387 Cooling IC engines E W WHEELER 21 Dec 1971 59322/71 Headings F1B and F1K An IC engine drives an air compressor the output air from which is passed through a jacket surrounding the engine so that the air is heated in cooling the engine and is then stored in one or more accumulators in order to be available for supercharging the engine. Rotary compressor A is mounted in front of the engine on the vehicle and supplies air at 40 p.s.i. which is cooled before passing to an accummulator D containing a piston loaded by a first-stage spring to give 20 p.s.i. and a second stage spring to give 40 p.s.i. From the accummulator the air passes to two cylinders of the engine which further compress the air to 280 p.s.i., at which pressure it is exhausted into an air jacket J surrounding the engine to act as a coolant. Air leaving the jacket J is stored in a second accummulator G of about 2 cu. ft capacity which again contains a piston loaded by two springs. The first spring produces a pressure of 60 p.s.i and the second spring a pressure of 250 p.s.i. Starting A third accummulator H also receives air from the jacket J and has a piston, spring- loaded to produce 100 p.s.i., the air from this accummulator being used to start the engine. The engine having been stopped by raising the accelerator pedal beyond the slow-running point, depression of the pedal opens a valve connecting the accummulator H to the engine. The valve is automatically closed by the back pressure when the engine fires. Conserving heat The exhaust pipes pass around accummulator G to heat the air therein. Engine temperature control Since the output of the compressor is proportional to engine speed, the amount of cooling air supplied will vary automatically with the speed of the engine, an excess of air being provided which is released through a valve L controlled by a thermostat in the wall of the air jacket J. A further valve M controlling the outlet from valve L is controlled by the pressure in accummulator H and closes to maintain 100 p.s.i. in the accummulator, even though cool running of the engine may have caused the thermostat to open fully the valve L.

Abstract: 1462198 Detecting largest smallest signals WESTINGHOUSE ELECTRIC CORP 28 Dec 1973 [3 Jan 1973] 59941/73 Heading G1U [Also in Divisions G4 and H3]  In an analog level detector having n inputs connected to non-inverting inputs of n amplifiers 58, 60-68 and n diodes D80, D82-D92 connected to pass the outputs of the amplifiers to perform an OR function at an analog output and to form a feedback loop between the inverting inputs and outputs of the amplifiers for feeding a reference bias voltage to the inputs so that the input signal having the extreme value is passed to the analog output, an encoder 94, 96, 98 is commonly connected to the amplifiers and is responsive to the input having the extreme analog value to provide a digital coded output having x bits where x is defined by 2<SP>x</SP> = n. As shown in Fig. 2A assuming the input 2 has the highest analog value the output of an operational amplifier 60 forward biases a transistor 70 and a diode 82 and makes the signal fed back to the inverting input of the amplifier 60 equal to the voltage at input 2. Since the same voltage is fed back to the inverting inputs of the other operational amplifiers 58, 62, 64, 66 and 68 and since all other inputs are less than input 2 all the other amplifiers 58, 62, 64, 66 and 68 will be saturated negative. As the transistor 70 is conducting a transistor 94 also conducts to make the binary output ABC equal to 001. The operation of the circuit when the other inputs are greatest is given by the table Fig. 2B. The detector may respond to detect the lowest input signal by using transistors of opposite conductivity type to those shown Fig. 3A, (not shown). The output signals from the operational amplifiers 58-68 fed back to their inverting inputs may be adjusted to equal their input voltages by a "trim pot" within the amplifier circuit. Diodes 82-90 prevent breakdown of the emitter-base junction of their associated transistor. Additional transistor circuitry Fig. 4, (not shown) including zener diodes (114, 116) connected to the analog output of the detector can be used so as to enable the level detector to accommodate high common mode input signals of the order of voltages (ŒVHV) supplied to transistors (118, 120) of this additional circuitry. A known level detecting transistor circuit which may be in integrated circuit form is disclosed Fig. 1A, (not shown).
