Patent GB-1108785-A (GB)
Title: Encapsulated halophors and methods for making same
Inventor: DALTON PHILIP BENJAMIN
IPC: C08F4/00
Filed: 1965-06-02
Abstract: A solid halophoric composition is prepared by treating a halogen-polymer complex in the solid state and under substantially anhydrous conditions with an ionic polymerization catalyst and thereafter polymerizing an ethylenically unsaturated monomer in contact with said comples. Halophors specified are complexes of iodine and, e.g. polymers of vinyl pyrrolidone, vinyl oxazolidone, vinyl imidazole, vinyl morpholone and vinyl caprolactam and copolymers, interpolymers and graft copolymers derived from such lactams; also oxyalkylene condensates, e.g. condensates of ethylene oxide and/or propylene oxide with alcohols, amides and phenols. Specified monomers are a -olefins such as ethylene, propylene and butylene, styrene, alkyl substituted styrenes, acrylates and methacrylates, acrylonitrile, vinyl halides and esters such as vinyl chloride or acetate, and vinyl ethers.  The polymerization is preferably carried out with the halophor suspended in an inert liquid in the presence of the catalyst, e.g. a combination of an organometallic compound and a transition metal halide or ester, particularly an alkyl, aryl, aralkyl or alkaryl compound of a metal from Group I, II or III of the Mendeleeff Periodic Table with a halide of a metal from Groups IV to VI, e.g. Ti, Zr, V, Cr or Mo. The particulate product may be moulded to form e.g. a sheet.  In Examples 1, 2, 5 and 3(a) to 3(e) ethylene is polymerized in a suspension of a polyvinyl pyrrolidone-iodine complex in toluene using TiCl4 and CH3MgBr as catalyst.  Similar processes are carried out in Examples 3(f) to 3(n) except that the complex is of iodine with an ethylene oxide-propylene oxide condensate, polyvinyl oxazolidone or a copolymer of vinyl pyrrolidone with vinyl stearate, vinyl chloride, or vinyl pyridine, or of iodine and bromine with polyvinyl oxazolidone; in Example 4 except that triisobutyl aluminium is the organometallic catalyst component; in Examples 6 and 8 except that isoprene or propylene replaces the ethylene; in Example 10, except that benzene, xylene or n-heptane replaces the toluene and in Example 7, except that the catalyst comprises (a) di-n-butoxy titanium dichloride and (C2H5)3Al, (b) CrCl3 and (C2H5)3Al, (c) VCl3 and triisopropyl aluminium, (d) ZrCl4 and n-butyl lithium or (e) ZrCl4 and (C2H5)2Cd.  Examples 4 to 8 are also repeated in Example 9, using the halogen-polymer complexes employed in Example 3.

Title: Demodulator for binary coded words
IPC: H03M1/00
Filed: 1971-04-19
Abstract: 1315749 Digital to analogue converters KRONE KG 19 April 1971 [9 March 1970] 23560/71 Heading G4H A circuit for decoding binary coded words in a P.C.M. system comprises a store 100 for receiving the incoming words, a first decoder D1 connected to the store and adapted to receive m most significant bits and n least significant bits of each word, a second decoder D2 adapted to receive the m bits from the store and weighted resistors KD1-RD7 connected to switches S1-S7 actuated by the output of the second decoder. The most significant bit of each word is a polarity bit which controls a switch BS 6  of the decoder D1, shown in detail in Fig. 4a, to supply a positive or negative reference voltage to a parallel arrangement of binary weighted resistors RB1-RB6. The resistors RB1-RB4 are connected in circuit by switches BS1-BS4 actuated by the n bits to select the particular one of the sixteen subdivisions (for n=4) of the amplitude band determined by the m bits. To remove the ambiguity due to the first two bands of the expansion characteristic having the same slope, the m bits are fed to an OR gate 111 which actuates a switch BS5 if any of these bits has a logical value "1". The output voltage from the parallel resistor network is fed via an inverting amplifier V to a potentiometer formed by the weighted resistors RD1-RD7. The decoder D2 comprises seven NAND gates which control the switches S1-S7 to multiply the output U A <SP>1</SP> of the decoder D1 by a factor which determines the amplitude band of the analogue output signal. The switches may be field effect transistors. In a modification the output from the resistor network RB1-RB6 is fed through a second inverting amplifier when the polarity bit changes over ganged switches connected to the outputs of the amplifiers. A ladder network replaces the network RB1-RB6 in a further modification.

Title: Improvements in apparatus for measuring the maximum demand demanded from an electricity supply
IPC: G01R11/60
Filed: 1920-08-13
Abstract: 168,514. Howarth, O. Aug. 13, 1920. Special quantities, registering.-A maximumdemand indicator has two indicating scales and pointers, geared together, one indication being a multiple of the other. The motion of the meter armature is transmitted to the primary pointer through two shafts carrying arms to enable one to engage the other and provided with screws, worms, or other gearing permitting, relative longitudinal motion between them, so that a single turn of one shaft relative to the other may cause engagement or disengagement. Two pointers h, k geared together and working over separate dials so as to give a large range of indication are operated by gearing f, g, l, m from a shaft E, and are frictionally restricted by a brake r. The meter armature operates, through ratchet or like disengoageable gearing a, n, b, a shaft B under the control of a zeroizing-spring p. The shafts B, E move longitudinally in their bearings under the influence of similar worms c, e. An arm B<1> on the shaft B thus clears a zero stop q after one revolution and engages an arm E' on the shaft E to drive the indicators. When the driving-shaft B is periodically reset, its arm B' clears the arm E' after one revolution in a similar manner. The screws c, e may be replaced by other suitable mechanism.

Title: Process of polymerising vinyl monomers
IPC: C08F4/00
Filed: 1961-07-03
Abstract: In a process of polymerizing monomers of formula CH2=CXR where X is hydrogen, alkyl or halogen and R is an organic radical to obtain a syrupy solution of polymer in the monomer, the polymerization is carried out in the presence of such a quantity of initiator and at such a temperature that the initiator is completely destroyed and the reaction automatically stopped once the desired conversion is reached, this conversion being lower than 70%.  The process may be carried out continuously by continuously feeding monomer and discharging syrup.  Specified monomers are acrylic and methacrylic esters, styrene, vinyl acetate and dimethyl itaconate.  The initiator may be an organic peroxide or hydroperoxide or an azo compound, e.g. benzoyl peroxide, lauroyl peroxide, di-t.-butyl peroxide, t.-butyl peracetate and azo-bis-isobutyronitrile, and chain transfer agents, e.g. n-butyl, octyl, 2-ethylhexyl and dodecyl mercaptans, may also be present.  Examples describe the preparation of syrups by polymerizing methyl methacrylate in the presence of (1) lauroyl peroxide, (2) lauroyl peroxide and n-butyl mercaptan and (4) t.-butyl peroxide and n-octyl mercaptan; and by copolymerizing methyl methacrylate with (3) styrene in the presence of lauroyl peroxide and (4) ethylene glycol dimethacrylate in the presence of benzoyl peroxide.

Abstract: 1465613 Fluid-pressure brake systems; lining- wear indicators TELDIX GmbH 30 May 1974 [30 May 1973] 24049/74 Headings F2F and F2E A vehicle brake control apparatus comprises means 21 for sensing the extent of actuation of a brake actuator 19, means 26 for determining the deceleration of the vehicle, and control means 25 for comparing the output signals of the sensing means and determining means and producing a control signal for control of at least one of the brakes 6, 7, 8, 9 so that a predetermined deceleration of the vehicle is associated with a predetermined extent of actuation of the brake actuator. On actuation of pedal 19, a valve 5 is raised to its top position to permit pressurization of wheel cylinders 6a to 9a. If the consequent vehicle deceleration is that called for, valve 5 is moved downwards to the intermediate position where pressure is stabilised. On pedals retraction, valve 5 is lowered to the position shown, where pressure is relieved by line 10 to reservoir 3. In the event of failure of pressure source 1, 2, 4, linked valves 11, 12 are automatically raised to isolate the wheel cylinders therefrom, after which the wheel cylinders may be pressurized by an emergency pressure generator 16, 17 upon sufficient movement of pedal 19. Alternative actuation of valves 11, 12 is by a mechanical connection 34 between valve 12 and a rod 35 forming part of the connection between pedal 19 and generator 16, 17. Modulating valves 13 to 15 are controlled by an anti-skid circuit 29 to which wheel speed signals and front-wheel deceleration signals are fed at 30, 31, respectively, and from which valvecontrol signals are derived at 32. A pendulum 26a and detector 26b form deceleration-determinant 26. Fig. 3 (not shown) depicts logic circuitry for operating valves 13 and 14, or 15, to prevent pressure rise on excessive brake-lining wear of a front or rear wheel. Such operation is suppressed if the anti-lock controller is in operation, or if the brake is actuated many times in a short time (vehicle descending incline), or if both front and rear linings are worn; in the lastmentioned case a warning lamp is energized.
