Title: Improvements in or relating to process for improving hydrocarbon resins
IPC: C08L57/02
Filed: 1953-04-07
Abstract: A substantially non-aromatic unsaturated hydrocarbon resin prepared by the Friedel-Crafts catalytic polymerization at - 100 DEG  C. to + 100 DEG  C. of a steam cracked hydrocarbon oil fraction of boiling range 20 DEG  C. to 280 DEG  C., is reacted at above 240 DEG  C. with 5 to 50 per cent of a coumarone-indene resin to raise the softening point.  The hydrocarbon resins may be prepared from mixtures of 10 to 35 per cent diolefins, 30 to 65 per cent olefins and 0 to 60 per cent of aromatics, paraffins and naphthenes, using catalysts such as aluminium chloride or bromide, boron trifluoride or solutions, slurries or complexes thereof, and quenching residual catalyst by methyl alcohol or water and/or caustic washing.  The coumarone-indene resins may be obtained from coal tar naphtha solvents of boiling range 150 DEG  to 200 DEG  C. which are refined by alkali and acid washing and redistillation and then polymerized with concentrated sulphuric acid followed by purification.  The reaction of the resins is preferably carried out in the substantial absence of oxygen so that the colour is not degraded.  Calcium carbonate, titanium dioxide, asbestos and pitch may be incorporated in the products to give compositions which are suitable as floor tiles.

Title: Multiple stable state electron-discharge tube circuits
IPC: H04B14/04
Filed: 1951-04-25
Abstract: 697,127. Pulse code modulation circuits; valve circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 25, 1951 [April 28, 1950], No. 9632/51. Classes 40 (v) and 40 (vi). A trigger pair circuit comprising two crossconnected valves selects one of its two stable states in dependence upon a control voltage supplied to it and a common part of the grid circuits of the two valves is biased, so that they tend to pass equal anode currents, a generator producing rectangular switch pulses being connected in series with the bias source. Fig. 1 shows a trigger pair circuit comprising crossconnected valves 1, 2 in which bias source 9 has such a value that the valves are non-conductive except during the positive peaks of the switch voltage Us when one of the valves is rendered conducting and the other cut-off in dependence upon the control voltage Ui applied to the auxiliary valve 16 which is connected in parallel to valve 1. The diodes 12, 13 limit the positive grid swing of the valves 1 and 2 and the variation of the output voltage Ua with the value of the bias voltage Uo is dependent upon the value of the control voltage Ui, Fig. 2 (not shown). Fig. 3 shows the application of a trigger circuit comprising hexode 20 and triode 21 in a modulator for a pulse code modulation of the type described in Specification 684,318. The speech to be modulated is applied at Ui and appears amplified across resistor 34 and the output pulses from the trigger-pair circuit 20, 21 produced across resistor 40 are integrated in the anode circuit 31, 32 of valve 30. Thus a control voltage is applied to the second control grid of hexode 20 equal to the difference between the voltages across resistor 34 and the integrator circuit 31, 32, the value of this voltage determining which of its two stable states the trigger pair circuit will occupy during the positivegoing positions of the switch voltage Us. The output signal across resistor 40 is differentiated by network 41, 42 and passed to a receiver which may, for example, be as shown in Fig. 4. The incoming time-multiplexed code modulated pulse train is applied as a control voltage at terminal 43 to the hexode valve 20 of the trigger-pair 20, 21, which has a switching voltage Us applied to it, the pulse repetition frequency of which is equal to the channel repetition frequency in the incoming multiplexed signal. The pulses at the output of trigger valve 21 are integrated in the anode circuit 31, 32 of valve 30 to produce a replica of the original speech modulation, the pulse output of the trigger pair being independent of the shape or amplitude of the input pulse train at terminal 43 and of any noise components present in the input signal.

Title: A method of carrying out an authentication check between a base station and a mobile station in a mobile radio system
Inventor: PAUL DENT WILKINSON
IPC: H04L9/32
Filed: 1995-06-22
Abstract: A method for carrying out an authentication check in a mobile telephone system in which an authentic base station (BS) serves a plurality of mobile stations (MS1-MSn). It is earlier known to carry out a unidirectional check from the base station (BS) to a calling mobile station (MSk). A false base station (BSf) is able, in this way, to carry out a false authentication check, by collecting a number of so-called RAND-Response pairs. In order to avoid this, there is introduced a further unidirectional authentication check, base station-mobile station, and also an authentication check from the mobile station to the base station. According to one embodiment of the method, the unidirectional check is excluded and only the bidirectional authentication check is carried out. <IMAGE>

Title: Fuel injector for internal combustion engine
Inventor: KONRAATO ETSUKERUTO
IPC: F02M59/26
Filed: 1981-01-09
Abstract: A fuel injection apparatus for internal combustion engines, in which the onset and end of injection are determined by a hydraulically actuated control slide. The injection pump of the apparatus, which is preferably combined with an injection nozzle to form a pump/nozzle unit, has a pump piston embodied as a differential piston, whose section having the larger diameter serves as an auxiliary pump piston and generates a control pressure (pS) actuating the control slide. During its compression stroke the control slide, in order to initiate the onset of injection, closes an overflow line leading out of the pump work chamber; and during its return stroke, which is effected by the pressure drop in the control line, the control slide relieves the overflow line in order to control the end of injection. The control pressure (pS) in the control line necessary for actuating the stroke movement of the control slide is controlled by the closure of this line by means of a control device and is built up during the compression stroke of the auxiliary pump piston.

Abstract: PURPOSE:To make it possible to perform highly accurate measurement regardless of environmental temperature by arranging a photodetector at the focal surface of a lens part through a supporting meber wherein materials having different thermal expansion coefficients are combined. CONSTITUTION:One end part of a first supporting tool 11, which is formed into a tube shape, of metal material having a length of L1 and a linear expansion coefficient alpha1 is attached to the base part of a lens part 10, wherein a single lens 10b is arranged in a lens tube 10a. A second supporting tool 12, which is formed into a tube shape having the bottom of metal material having a length of L2 and a linear expansion coefficient alpha2 is assembled and provided in the supporting part 11. A photodetector 13 is arranged on the focal surface of the lens 10 at the bottom part of the supporting tool 12. At this time, the focal distance (f) of the lens part 10 is changed to f+ DELTAf.T based on the changing temperature of T degree of the environmental temperature, and the detector 13 is displaced accompanying the displacements of the supporting tools 11 and 12.
