Title: Improvements in the manufacture and production of interpolymerisation products
IPC: C08F236/04
Filed: 1937-06-24
Abstract: A rubber-like product is obtained by treating a mixture of butadiene, or an alkyl, aryl, or chlorsubstitution product thereof, and a vinyl ethinyl carbinol.  Specified ingredients are butadiene, isoprene, 2.3-dimethylbutadiene, 2-phenylbutadiene, monochlor- and dichlor-butadienes, vinyl ethinyl dimethyl carbinol, 1-vinyl-ethinyl-cyclohexane-1-ol, vinyl ethinyl ethyl methyl carbinol and vinyl ethinyl-di-isopropyl carbinol.  The polymerization may be carried out by heating the mixture of the monomers in the presence of per-compounds, and if desired under pressure, or in aqueous emulsion. The interpolymers are practically insoluble in organic solvents, may be mixed with fillers or dyestuffs, and may be vulcanized, after the addition of vulcanizing agents, vulcanization accelerators and, if desired, agents protecting against ageing, to form articles similar to soft or hard rubber.  In examples: (1) butadiene and vinyl ethinyl dimethyl carbinol are heated in a closed vessel in the presence of benzoyl peroxide; (2) beta-chlorbutadiene and vinyl ethinyl dimethyl carbinol are heated in a closed vessel with benzoyl peroxide; the interpolymer produced is mixed with colophony, a softener obtained by extracting lignite low temperature carbonization tar with ethyl alcohol, gas carbon, zinc oxide, magnesium oxide, sulphur and N-phenyl-, beta-naphthylamine and treated to form a product resembling hard or soft rubber depending upon the proportions of the ingredients used to form the interpolymer; (3) beta-chlorbutadiene and vinyl ethinyl dimethyl carbinol are emulsified with water, ammonia, oleic acid and benzoyl peroxide, and the emulsion heated; the interpolymer is heated in the mixture described in example 2 to yield a product similar to hard rubber; (4) beta-chlorbutadiene and 1-vinyl-ethinyl-cyclohexane-1-ol are heated in a closed vessel with benzoyl peroxide; and (5) butadiene and vinyl ethinyl dimethyl carbinol are emulsified with an aqueous solution of sodium oleate, ammonium persulphate is added, and the mixture heated in a closed vessel; a small amount of phenyl beta-naphthyl amine dissolved in benzene or dispersed in water is then added and the interpolymer coagulated by the addition of sodium chloride and acetic acid.

Title: Improvements in or relating to safety circuit arrangements for multiplier tubes
IPC: H03F1/54
Filed: 1956-06-08
Abstract: 791,375. Circuits for electron multipliers. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 8, 1956 [June 11, 1955], No. 17793/56. Class 40 (6). The current in a multiplier tube is limited to a safe value by connecting a diode in series with the supply to one of the secondary emission electrodes and a resistance from that electrode to a point of lower potential. In the embodiment, a photomultiplier has the potential between anode 9 and electrodes 5 to 8 normally stabilized by gas-discharge tubes; the current in the germanium diode 21 is equal to that in resistor 22 reduced by that flowing from electrode 7. Under incidence on the cathode 2 of excessive light, the emission from electrode 7 may become sufficient to cause the voltage drop in resistor 22 to exceed that of the gas tube 17, 18, thereby cutting-off the diode 21 so that further increase in emission from electrode 7 reduces the voltage between electrodes 7 and 8, hence preventing further increase in multiplication in stages 7-8 and 8-9. The multiplication in stage 6-7 will increase slightly but further increase in the current in resistor 22 will reduce the gain by saturation. Two variable resistors 15, 16 are provided as gain controls.

Title: Improvements in or relating to devices for measuring liquid flow
IPC: G01F1/58
Filed: 1956-06-08
Abstract: 834,011. Electric tests. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 8, 1956 [June 11, 1955], No. 17795/56. Class 37. In an induction flowmeter in which an alternating field is used, voltages induced between electrodes 3, 3<SP>1</SP> by direct coupling are eliminated by feeding the electrode output through a phase-sensitive circuit 7 which is also fed with a reference voltage derived from auxiliary coils 4, 4<SP>1</SP>, energized by the alternating field. The required measuring voltage produced between the electrodes is 90 degrees out of phase with the reference while that produced by transformer action is 180 degrees out of phase. The coil output is amplified at 15 and the electrode output at 5. Meter 9 gives an indication which is independent of voltages induced directly between the electrode. Fig. 2 shows an arrangement in which the output is independent of field strength. The output of coil 4 is amplified at 15, integrated by R.C. circuit 10, 16 or by a frequency-sensitive back-coupled amplifier, rectified at 12, and the ratio of this voltage and the electrode output determined at 14 to indicate a rate of flow on meter 9 which is independent of field strength and frequency variations.

Title: Installation for transmitting fluid or fluid pressure
IPC: B60R17/02
Filed: 1924-07-25
Abstract: 241,631. Bijur, J. July 25, 1924. Connecting fixed lubricators with moving apparatus. - Fluid is transmitted from one to the other of two relatively movable parts through a continuous length of resilient conduit rigidly secured to the two parts, the conduit being helically coiled to form a hollow spring adjacent to either or both of the points of rigid attachment. As applied to a conduit 12, Figs. 1 and 2, leading lubricant from the frame of a vehicle to the rear axle, the hollow spring part 20 is arranged coaxial with the hinge pin 11 of the rear spring, the first turn of the helix being secured by clips 13, 14 to the end of a cap 15 enclosing the helix and secured to the spring bracket 18 by bolts 17. The conduit emerges from the cap 15 through a hole 20 and extends along the side of the spring to the axle, being anchored to the spring at intervals by clamps. Each clamp comprises a pair of jaws 21, 22, Fig. 3, the outer legs of which have lips 24 which are caused to engage under the upper leaf of the spring by a nut 27 on a bolt 26 passing through the jaws. The conduit 12 is held in a clip 25 mounted on the bolt 26 between the nut 27 and a washer 28 spacing the conduit from the spring. As the vehicle spring flexes, the helix winds and unwinds to accommodate the hinging movement, while the length of conduit extending along the spring Hexes therewith to accommodate the changes in distance between the frame and the axle. For conveying lubricant from the frame to the front, axle along the front spring, one end of the helix 81, Fig. 4, is secured by screwing on a threaded stud 34 to a bracket 36 on the frame, while the other end is secured in a similar manner to a bracket 39 formed integral with a clip 38 straddling the upper leaf of the spring, the conduit extending from this end along the spring. The helix, the axis of which is distorted during flexure of the vehicle spring, is arranged so that it is under minimum strain when the vehicle spring is in a position midway between the positions of maximum compression and rebound, the axis of the helix in this position extending through the centre of the hinge pin h. For conveying lubricant from one side of the frame to the axle on the opposite side, the frame end of the conduit is formed into a vertical helix 40, Fig. 5, and the axle end is formed into a horizontal helix 43, the intervening length of conduit 42 being mounted on a light rigid runner 45 held at its end by leaf springs 46, 47 secured to the frame and axle respectively. Arrangements for conveying lubricant from the frame to other relatively movable parts are described.
