Title: Fluid pressure operation of devices such as printing hammers
IPC: F15B11/06
Filed: 1962-07-25
Abstract: 944,687. Selective printing. SPERRY RAND CORPORATION. July 25, 1962 [Aug. 16, 1961], No. 28535/62. Heading B6F. Apparatus for applying an impulse of short duration to a member, such as a printing hammer 16 1 , which is situated at the end of a chamber 38 1  and is movable only when the pressure in the chamber rises above a certain magnitude, comprises a sealed piston 28 1  to which momentum is imparted to decrease the volume of and increase the fluid pressure in the chamber 38 1 , the arrangement being such that the pressure in the chamber does not increase to a sufficient value to operate the hammer until the piston is nearing the end of its travel towards the hammer. The hammer is held in its retracted position by an external pressure or a spring. Momentum is imparted to the piston 28 1  by the admission through a port 32 1  of a fluid pressure impulse to the side 40 1  of the piston, this pressure being such that the pressure in the chamber 38 1  does not rise to the same value until the piston is nearing the end of its travel. The input pressure may be constant or may decrease as the piston moves towards the hammer, and is terminated either prior to or subsequent to the time when the hammer begins to move. Thereafter the high pressure in the chamber 38 1  which may be increased by hammer rebound causes the piston to be returned to its initial position. The end 29 1  of the piston may be tapered and the end 27 1  of the chamber 38 1  similarly shaped. As applied to printing mechanisms for pneumatic data-processing systems a number of hammers 16 1  ... 16 N  selectively operated from a control source 36 co-operate with rings of type 24 1  ... 24 N  on a rotating cylinder 20 or on rotating type wheels.

Title: Improvements in and relating to television and the like systems
IPC: H04N3/12
Filed: 1933-10-19
Abstract: 432,017. Television. WALTON, G. W., 2, Dean Street, Soho, London. Oct. 19, 1933, No. 29001. [Class 40 (iii)] A plurality of simultaneously operative scanning-apertures A .. K co-operate with a less number of transmittihg-channels. A one-dimensional equivalent of an object 11 produced by an apparatus 10, as described in Specification 328,286, [Class 40 (iii)], is swept at a regular speed over the apertures by a rotating mirror drum 12. A photo-electric cell A1 .. K1 behind each aperture is connected to a corresponding coil A2 .. K2 on a stationary distributer. The signal from each cell comprises a fundamental frequency, which is the frequency of scanning, together with harmonics. Most of these produce rotating fields in the distributer, which are picked up by secondary windings 4, 5, 6 and transmitted over separate channels or a three-phase channel, Fig. 10 (not shown). A converse arrangement is used at a receiver. Two or more distributers may be used in series, Fig. 11 (not shown). Some harmonics produce stationary or oscillating fields which cannot be properly picked up by the secondary coils. To overcome this difficulty, three distributers are used in parallel with their windings differently arranged, Figs. 12 and 13 (not shown). The two-phase output may be combined in a single phase by a Wheatstone bridge arrangement, Fig. 16 (not shown). Electrostatic distributers may be used, Figs. 14 and 15 (not shown). Specifications 379,303 and 403,395 also are referred to.

Title: Substituted phenoxyacetic acids
Inventor: PRESTON ROBERT WILLIAM GUNN
IPC: C10L1/18
Filed: 1956-04-23
Abstract: The invention comprises substituted phenoxyacetic acids having the formula <FORM:0815050/IV (b)/1> in which R1 is n-octyl, 1-methyl-1-ethyl-pentyl, the radical derived from propene trimer of boiling-range 130-140 DEG  C., or the radical derived from propene tetramer of boiling-range 181-218 DEG  C.  The compounds may be produced by reacting chloracetic acid with therequisite para-alkylated phenol in the presence of an alkali.  For example, para-nonyl phenol is produced by alkylating phenol with propene trimer, and the product is treated with chloracetic acid in the presence of alkali metal hydroxide. Para-nonyl phenoxyacetic acid is isolated from the salt so produced.  The abovementioned phenoxyacetic acids have use as corrosion-inhibitors for hydrocarbon fuels such as aviation fuel.

Title: Improvements relating to the preparation of phosphonitrilic chloride polymers
Inventor: RIDGWAY FREDERICK ARTHUR
IPC: C01B21/098
Filed: 1961-08-14
Abstract: Phosphonitrilic chloride polymers are produced by bringing into contact gaseous elemental chlorine, phosphorus trichloride and ammonium chloride in an inert solvent at reflux temperature, the ammonium chloride being present at any time during the reaction in a proportion at least equimolecular with the phosphorus trichloride. Reaction may be effected by adding Cl2 to a mixture of phosphorus trichloride and ammonium chloride in an inert solvent, by adding Cl2 and phosphorus trichloride simultaneously to an ammonium chloride solution or by continuously adding all 3 reactants to the refluxing solvent. Solvents specified are phosphorus oxychloride, tetrachloroethane, chlorobenzene, o-dichlorobenzene and benzyl chloride.  The addition may extend over a period of at least 50% of the total reaction time, but in Example 3 occupies less than 50% of the reaction time.  It should be at such a rate that the rate of evolution of HCl is 40-100% that predicted by the equation PCl3+Cl2+NH4Cl-->PNCl2+4HCl.  Anhydrous metal chlorides capable of complexing with NH3, e.g. cobaltous, aluminium, cupric and zinc chlorides, act as catalysts and the reaction can also be accelerated by using finely divided ammonium chloride and using it in excess, e.g. at least 10% excess of ammonium chloride of a specified surface area of at least 1000 sq. cm./g.  Specification 905,315 also is referred to.

Abstract: 1,058,814. Ethyl alcohol, purification by batch distillation. W. H. A. WEBB. July 21, 1965 [July 22, 1964], No. 29586/64. Heading BIB. Ethyl alcohol is purified by distilling a batch of the alcohol in a large vessel A connected to a fractionating column B, condensing the vapour rising from the upper end of the column in a condenser C and recycling the condensate as reflux after bleeding off part of the condensate at D and adding water through line Z at a controlled rate, the ratio of alcohol to water in the liquid phase throughout the column being in equilibrium with the ratio in the vapour phase throughout the column and within the range to effect hydroselection of impurites. The liquid discharged at D is enriched in impurity. Steam is injected into the column through pipe X, and by modifying the amount of steam injected and heat applied at Y the vapours entering the column are maintained at constant composition. In a modified apparatus (Fig. 2, not shown), a batch of hot liquid alcohol is circulated through a middle section of the column and a reservoir vessel, the lower section of the column is provided with an auxiliary condenser, and a pipe is provided for discharging water from the bottom of the column. This water may be added to the reflux at the top of the column. In a third embodiment (Fig. 3, not shown), the column is connected to an auxiliary column, and part of the distillate from the latter is recycled to the reservoir vessel which supplies the batch of alcohol-to-be-purified to the main column.
