Filed: 1947-06-26
Abstract: 639,665. Printing-machines. CHANDLER & PRICE CO. June 26, 1947, No. 16868. Convention date, July 26, 1946. [Class 100 (ii)] A printing-press similar in construction to a platen press but in which a curved platen 51 is employed which prints in coaction with a flat bed 47 in such a way that the pressure is applied line by line as in a cylinder machine with a plane surface is constructed so as to print with a true rolling motion without any slippage, the curved platen being formed of large curvature such as a radius of 7.5 feet, and an extension 52 of the platen is pivoted at 53 to an oscillating frame 3 which is moved to and from the fixed bed by toggle mechanism 19, 21, 23 operated by crank-pins 18 on wheels 12 driven by gearing from a motor 5. The pressure exerted by the platen 51 is controlled by hydraulic or other means so as to be substantially constant throughout the printing operation, and at the end of the printing operation when the platen 51 has reached the position shown in Fig. 3, the frame 3 is moved clockwise towards the open position shown in Fig. 1, prior to the return movement of the platen 51 relatively to the frame 3 so that double impressions are avoided. The bed is inked by travelling rollers 34 which receive ink from a roller 27 all operated in known manner. The hydraulic pressure control means comprises a pressure cylinder 57 with a piston operated by a lever 69 and a cam 72 to transmit pressure via pipes 59, 62 to a pair of cylinders 64 fitted with pistons having rods 66 connected to the platen 51. The cylinders 64 are mounted on the frame 3, and as the frame 3 moves towards printing position the hydraulic pressure is at its maximum and moves the platen clockwise relatively to the frame 3 against the action of springs 77, the movement being limited by pins 76 on the frame 3 which engage slotted links 73 connected to the platen 51. When printing commences a cam 72 permits the piston 68 to move to the left and the pressure in cylinders 64 is released gradually and the arrangement is such that a constant printing pressure is effected due to increase of the mechanical pressure. The invention may be applied to machines in which the typebed is the oscillating member. Specifications 14805/05, [Class 100], 174,445, [Class 100 (ii)], and 639,664 are referred to.

Abstract: 1,034,639. Small arms; ammunition for industrial tools and rifles. CORAT S. A. COMPAGNIE DE RECHERCHES ET D'APPLICATIONS TECHNIQUES. April 22, 1965 [April 22, 1964], No. 16963/65. Headings F3A and F3C. [Also in Division B4] A cartridge-actuated device, such as a firearm, comprises a compressed-air pump 17, 18, for increasing the pressure in a loading chamber 3a, Fig. 3 (not shown), in order to ignite the cartridge, the pump having a piston 12 which can be moved to a cocked position against the action of a spring 11 by means of a lever 5 and released by a trigger mechanism. The piston, which is formed with a skirt 14 having a slot 15, is slidable in a cylinder 8 adapted to be moved by a handle in order to permit a cartridge to be inserted into the chamber 3a. The cylinder is provided with a head 9 having a chamber 9b in which a valve 31 is located and normally urged away from its seat 37 by a spring; the chamber 9b communicates with a compression chamber 30 by means of passages 28, 29 and grooves 36. In operation, in order to fire the device, the piston is moved rearwardly by means of a lever 5 which is connected to a link 6 having a lug 16 adapted to engage with the end of the slot 15; the piston is retained in this cocked position by the trigger mechanism. The cylinder 8 is moved rearwardly so that a cartridge can be inserted and is then locked in the position shown. Upon release of the trigger mechanism the piston compressses the air in the chamber 30 so that increased air pressure acts on the cartridge via the passages 28, 29 and grooves 36 thereby igniting it. The expansion of the explosive gases causes the valve 31 to shut and drive out the projectile. The cartridge unit for the device comprises a projectile part 41 which is to be fired and a cartridge case 42 fixed thereto which contains the propallent charge 43, 44, the part 41, prior to the propulsion thereof, forming a valving means for sealing off the rear end of the barrel of the device. The explosive charge 44 may be stabilized and treated gun-cotton capable of igniting under the action of a Diesel effect thereby firing the main explosive charge 43; alternatively, the two charges may be mixed to form a charge capable of igniting spontaneously. The portion 42 of the cartridge unit may have a gas escape hole and be formed on its inner end with an annular rib 47 for guiding purposes.

Abstract: 911,004. Frequency discriminators. ZKL VYZKUMNY USTAV PRO VALIVA LOZISKA. May 13, 1960 [May 15, 1959], No. 17062/60. Class 40 (5). [Also in Groups XIX and XXXVIII] A frequency discriminator comprises an input amplifier E1 and phase-splitter E2 to obtain equal and opposite voltages on the anodes of diodes E4, E5, to the common cathode of which are applied voltages varying in magnitude and phase according to the frequency of the input. These latter voltages are obtained from two CR circuits, C 1 , R 4  and C<SP>1</SP> 1 , R<SP>1</SP> 4 , shunted across the phase-splitter load resistors. The output voltage obtained between points 12 and 13 will be zero for a definite input frequency, and will vary in magnitude and polarity according to the magnitude and direction of deviation of the input frequency from this value. To prevent a false indication if the input should fail, a voltage is injected from the heater circuit to the screen grid of E1. The frequency of this signal is lower than the range of frequencies represented by the input signal, so that a finite output will be obtained from the discriminator when no input is supplied.

Patent GB-765334-A (GB)
Title: Process for separating ethyl acetate from liquid mixtures by extractive distillation
IPC: B01D3/40
Filed: 1952-07-07
Abstract: Ethyl acetate is separated from complex liquid mixtures by passing the vapours of the mixture up a fractionating column while introducing into the upper part of the column an auxiliary liquid which both extracts the ethyl acetate (thereby washing the ethyl acetate down the column) and in part distils azeotropically from the head of the column with at least one other component of the mixture. The process is particularly applicable to mixtures containing ethyl acetate, water and ethanol; in this case an auxiliary liquid is chosen which forms an azeotrope with water. Auxliary liquids referred to are:- butyl acetate, amyl acetate, dibutyl ether, xylene, and chlorinated hydrocarbons.  A mixture comprising ethyl acetate (92.3 per cent), water (3.6 per cent) alcohol (2.4 per cent) and acetone (1.7 per cent) is distilled in a column (3 metres high and 4 cms. wide), and butyl acetate is introduced into the top of the column. The mixture which collects at the base of the column contains butyl acetate and about 98.7 per cent of the ethyl acetate present in the original mixture.  The remaining components pass overhead in the vapour state together with butyl acetate.  The overhead vapours are condensed; and the condensate is allowed separate into two liquid layers, which are decanted.  The upper layer consists mainly of butyl acetate, while the lower layer consists mainly of water. The two layers are submitted separately to fractionation in order to separate the more easily volatile constituents from the butyl acetate and from the water.  The combined distillates (which amount to about 6 per cent of the original mixture) contain ethyl acetate (36.9 per cent), water (10.8 per cent), acetone (21.5 per cent) and alcohol (30.8 per cent); and is worked up in the usual manner.
