Patent GB-950067-A (GB)
Title: Polymerization process
IPC: C08L23/16
Filed: 1960-02-29
Abstract: Copolymers of ethylene and propylene are prepared by (a) forming a mixture of ethylene and propylene in a ratio falling within a predetermined range (b) polymerizing at a rate tending to drive the ratio outside the predetermined range, using as catalyst an organometallic compound and a Friedel-Crafts compound and (c) repeatedly or continuously during polymerization altering the ratio of ethylene and propylene so that it lies within the predetermined range. Modifying polar compounds and carriers e.g. carbon black may also be present.  The restoration of the monomer ratio may be done by adding further material richer in ethylene than the mixture, or by adding further material progressively richer in ethylene.  Monomer material containing ethylene and propylene may be added incrementally and either polymerizing all the monomers before adding the next increment or partially polymerizing and venting the remainder before adding the next increment. The monomer mixture may also contain preferred polymer or a third monomer e.g. a conjugated or non-conjugated diene. Typical ratios are propylene 35 to 95% and diene (if present) 0.5 to 5.0%. The copolymer may be mixed with 5 to 99% of a natural or synthetic elastomer and vulcanized. Specifications 821,971, 873,656, 873,657, 936,132, and 937,971 are referred to.

Abstract: 140,103. Crida, G. March 11, 1919, [Convention date]. Thermostats.-In apparatus for automatically maintaining the temperature of a room between predetermined limits, the valve or the like controlling the supply of steam or other heating agent is controlled by a reversible electric motor 7, operated by two circuits opened or closed by contacts in the wall of a mercury thermometer 1. A fixed terminal 2, and alternative minimum temperature contacts 3, 3<1>, and alternative maximum contacts 12, 12<1> with plug switches, are in the circuit of the low-tension coil of a transformer 4, the circuit including also a spiral switch 13 on the shaft of the motor 7, so arranged that the appropriate motor circuit is broken when the valve is fully closed. In operation, when the temperature of the room is below the desired minimum. the electro-magnet 5 is inactive and the circuit from the high-tension coil of the transformer 4 is closed through the special switch 8 on the motor shaft and the coil of the motor 7 for opening the control valve, the circuit being broken automatically by the spiral switch 8 when the valve is fully open. On the mercury reaching the minimum contrast, the circuit is broken by the electro-magnet 5. The further ascent of the column to a maximum contact energizes an electro-magnet 17 and closes the switch 19 in circuit with the coil of the motor 7 for closing the control valve.

Title: Processes wherein a mound of liquid is raised by acoustic vibrations
Inventor: BUTTERWORTH HAROLD MILLMAN
IPC: C11D1/62
Filed: 1965-02-22
Abstract: 1,082,874. Ultrasonic wave couplings; valve oscillating circuits. M.E.L. EQUIPMENT CO. Ltd. Nov. 23, 1965 [Feb. 22, 1965], No. 7546/65. Headings H3F and H4J. [Also in Division B3] Printed circuits are soldered by a mound of molten solder locally raised by discrete pulses of acoustic vibrations. The mound height is increased compared with that achieved by continuous vibrations. A magnetostrictive element 13 and probe 15 are immersed in a solder bath. In use, an intense acoustic wave is generated in the solder and pressure effects at the solder-air interface produce a solder mound following the outline of the probe 15. Printed circuit boards are passed across the mound and their surfaces are wetted by the solder. Cavitation effects assist wetting and radiation pressures cause solder to adhere neatly to joints. A 50 c/s. voltage supply is applied to line 5 and the potential at the anode 2 of triode 1 is varied above and below the cathode potential. When the anode 2 is positive with respect to the cathode 6, triode 1 conducts and current flows through the primary 3 of transformer 4 which in turn causes current flow in the secondary 11. The magnetostrictive element 13 is energized and the vibratory energy produced causes a pick-up transducer 17 to vibrate. By the reverse magnetostrictive effect a potential is produced across a winding 16 and applied to grid 8. This potential alternates at a frequency decided by the mechanical resonance of the magnetostrictive system. Loop phase and gain are arranged so that the initial vibrations are maintained and automatic frequency control is obtained. In the arrangement described the transducer vibrates and is interrupted for identical periods of 10 m/s. If unequal periods are required a switched D.C. power source is used. The transducer may then vibrate for 20 m/s. and cease for 1 to 10 m/s. Reference has been directed by the Comptroller to Specification 846,961.
