Abstract: 584,375. aerial masts ; rods. KREMER, H. Feb. 25, 1944, No. 3567. [Class 20 (i)] [Also in Groups XXV and XL] A flexible rod, e.g., for dowels or aerials comprises a core of solid or laminated or composite material over which a covering of one or more layers of uncured plastic material is wound the rod &c. being completed by curing the plastic material. An aerial rod may be made by consolidating a laminated sheet of fabric layers impregnated with synthetic resin, by heat and pressure, cutting the sheet into square-section strips, and passing the strips through a dowelling machine to produce cylindrical or tapered rods 12, Fig. 2. Copper wire 13 coated with resin cement, or flat strips of resin-coated copper or thin conductive sheet metal are then wound helically on the rods. Alternatively, thin metal sheets of a width equal to the length of the rods may be wound on the rods. Each core formed by a rod and metal winding is served with a coating of resin cement after which one or more layers, e.g., 14, 15 of resin-impregnated fabric tape or sheet material of width equal to the length of the rod are wound on the cemented core. The assembled core and covering are then placed in a mould and subjected to heat and pressure to cure the covering and to consolidate the rods.

Abstract: 493,346. Inductances and transformers. FERROLYTE SOC. A.R.L., and KAUFMAN, A. Feb. 6, 1937, No. 3604. [Class 38 (ii)] A high frequency coil or transformer is mounted by means of a plate of insulating- material having a hole or recess in which the coil or transformer is located and fixed by resilient fixing means made of insulating- material and frictionally engaging the walls of the hole or recess. In the form shown in Fig. 1, the coil 3 is provided with a powered iron coil 4 having a rectangular hole through it through which are passed resilient strips 5 of insulating-material located on either side of the plate 1 to locate the coil in the recess 2. In a modification, Fig. 3, the coil has an ironclad form of core with diametrically opposite slots 17 to engage a restricted section 18 of the recess 19, the coil assembly being retained in position by a resilient strip 15 sprung into slots in the plate 11. A further form is shown in Fig. 6, in which the coils 46 and cores 41, 42, are mounted by means of an insulating tube 43 which is slotted at 43<1> to engage the bottom edge of the recess 51 in the plate 50 and has slots 48 in the flange 47 to engage the lugs 49, the coil assembly being retained in position by a resilient disc 52 sprung between the lugs 49. In this form the core 42 has a screwed mounting 45 to permit of adjustment. The Specification states that a trimming condenser may be similarly mounted. Fig. 11 shows a coil assembly in which coils and a trimming condenser are supported by an insulating plate 201 which is mounted within a screening can 200. The plate has locating lugs 203 which engage slots in the can. The connectors for electrical connection are formed by strips 204 of metal attached to projecting lugs 205 of the insulating plate. This form of connector reduces the amount of inter-capacity.

Title: Preparation of titanium chloride acetate powder material
IPC: C07F7/00
Filed: 1953-02-10
Abstract: Titanium dichloride diacetate powder is prepared by a process which comprises preheating separately titanium tetrachloride and glacial acetic acid to the vapour state and reacting the vapours in a reaction zone at a temperature of between 136 DEG  C. and 170 DEG C., removing the gaseous hydrogen chloride from the reaction zone and collecting the resulting titanium dichloride diacetate powder.  In examples the process is carried out using stoichiometric proportions (I) and with about four times the stoichiometric amount of acetic acid (II).  For comparison liquid glacial acetic acid and liquid titanium tetrachloride were reacted using the proportions employed in examples I and II.  The product of (I) is converted to titanium dioxide pigment by heating in air (see Group III).ALSO:Rutile is produced by heating titanium dichloride diacetate (see Group IV (b)) to a temperature of 850 DEG  C. in the presence of air.

Abstract: 971,362. Cold separation of gas mixtures. PETROCARBON DEVELOPMENTS Ltd. Sept. 25, 1963 [June 30, 1962], No. 3745/62. Heading F4P. Carbon dioxide is freed of more and less volatile impurities, e.g. methane and butane respectively by two-stage separation in high and low pressure columns 9, 13, the former having a reflux condenser 14 which serves as the reboiler for column 13 and from which the gaseous methane fraction is discharged through duct 21 whilst partly purified liquid carbon dioxide collecting at the bottom of column 9 is withdrawn and expanded at a valve 23 into column 13 from the base of which liquid butane is withdrawn through a duct 24 whilst pure carbon dioxide is withdrawn as top gas. The effluent gas is warmed in an exchanger 16, compressed at 17 cooled in exchangers 18, 16, condensed in a reboiler 11 of column 9 and liquid carbon dioxide is collected in a tank 12. A portion thereof is withdrawn through a duct 27 and is expanded at a valve 28 into the head of column 13 to provide reflux. Crude feed gas after being cooled by an external refrigerant in an exchanger 2, is dried in regenerators 4, cooled in an exchanger 15, traversed by separated hydrocarbons, condensed in a reboiler 10 of column 9 and expanded at a valve 20 into said column 9.

Title: Improvements in or connected with automatic weighing apparatus
Inventor: TERRY FRANCIS SIEVWRIGHT
IPC: G01G13/00
Filed: 1950-02-15
Abstract: 697,787. Automatic feed weighers. AVERY, Ltd., W. & T. May 15, 1951 [Feb. 15, 1950], No. 3810/50. Class 143. In an automatic feed weigher the weighing receptacle is supported from an automatic dial indicating counter-balancing mechanism. Material is fed from a hopper 10 down a vibrating shoot 11 into the receptacle 13 which is supported on one end of a weigh beam 15, the other end of which is connected by a rod 18 and a lever 20, with the rod 23 of an automatic dial indicating counterbalancing mechanism 24 which may have either a spring or a pendulous resistant. The lever 20 also carries a U-bracket 25 fitted with adjustable abutment members 26, 27 which, when the bracket moves downwardly, successively operate a pair of switches 35 (one only being shown in Fig. 2) through a pair of pivoted arms 31 and a pair of double armed trigger catches 33, to effect first a dribble feed by reducing the frequency and/or amplitude of the vibrations of shoot 11, and finally cut off by open circuiting the vibrator 12. Simultaneously with cut off, solenoid 36 is energized and, through a pair of bell cranks 39, 41 and 43, 45, unlatches a catch 47 and allows the discharge door 48 to open under the weight of the charge; after discharge the door is closed again by a counterweight 49. Upward movement of the empty receptacle causes abutment members 28 on the bracket 25 to raise arms 31 which, through trigger catches 33, operate the switches 35 and so restart the weighing cycle. Whilst the door 48 is open, an extension arm 50 of bell crank arm 39 further open circuits the vibrator by operating a switch 51; this arm 50 also operates a counter 53. A hand lever 58 is provided to release a guide plate 57 to allow it to pivot to the right and so permit material to flow freely through the apparatus in the event of electrical or mechanical failure. A manual control 55 is provided to vary the frequency and/or amplitude of the vibrations of shoot 11 to suit different materials, and a switch 56 is provided to stop the feed at any point in the weighing cycle.
