Title: Process for the preparation of printing formes without etching
IPC: B41C3/06
Filed: 1953-02-23
Abstract: 783,170. Printing-surfaces. HEUSSNER, G. Feb. 23, 1953 [Feb. 25, 1952], No. 5062/53. Class 100(2) A process for manufacturing photogravure printing plates comprises the steps of forming a relief of colloidal material such as gelatin upon and supported solely by a member of thermoplastic material such as unvulcanized rubber, heating the member pressing the relief into the heated member, cooling the member, and washing out the relief to leave an impression thereof in the surface of the member. The relief comprises discrete particles of colloidal material, the heights of the particles varying in dependence on changes in grey values over the print to be made. Continuous tone negatives are made from the originals, while black-and-white negatives are made of type or other matter to be added. The negatives are retouched. From the negatives, a mounting is assembled which corresponds to the forme to be printed. Either the negatives are provided with a screen, or the mounting is covered with a negative photogravure screen. A copy is made from the mounting on sensitied gelatin on a backing sheet and transferred to the thermoplastic material. The backing sheet, which is outermost, is then removed with the aid of water and the layer of gelatin developed and dried to form the relief. Alternatively, the thermoplastic material may be provided with a sensitized gelatin layer on to which the copy is made directly. The relief is then covered with a smooth solid plate and pressed into the thermoplastic material by heat and pressure, then being washed out. In the preparation of intaglio printing-cylinders, the thermoplastic plate provided with the relief is mounted on a cylinder before the pressing takes place, or the cylinder is previously covered with the thermoplastic material, the relief is formed direct on the cylinder, and a flexible plate is stretched over for pressing. The imprint can be removed by heating and pressing with a smooth plate, so that the thermoplastic material can be used again.

Ascension pipes and hydraulic mains.-The gases and vapours produced by distilling tar by contact with part of the, hot gases from a battery of coke ovens are collected in a short main and mixed with the remaining gases which have been previously cooled to remove the heavy tar constituents in the usual collector main, and the mixture obtained is cooled to recover condensable constituents. A battery of coke ovens 1 of the usual type is provided with a collector main 6 of usual construction and a short collector main 7.

The pipe 3 is covered by a removable baffle 11 on which the tar to be distilled is sprayed from a pipe 13. The heavy residues are collected in an annular chamber formed beween the pipe 3 and the casing 4 and are removed through a pipe 14. By manipulation of the valves 8, 9 the retorts delivering to the short main may be selected at will. The main portion of the retort gases is withdrawn through pipes 22, the main 6 where it is cooled, and a collector main 23 to condensers 24, 25 while the tar formed in the main is run to a tank 28, from which it is withdrawn through a dehydrator 29 by a pump 30 to the spray nozzles 12.

Title: Improvements in receivers for time modulated electrical pulses
IPC: H03G11/00
Filed: 1942-04-21
Abstract: 581,731. Pulse modulation. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA, P. K., and SCULLY, C. T. April 21, 1942, No. 5366. [Class 40 (v)] In a receiver for time-modulated electric pulses, the amplitude of the pulses is limited between two levels dipping by a predetermined amount, the said being varied in accordance with the power of the incoming signals, or with the level of interfering noise. As shown, modulated carrier is applied through a transformer T to a diode rectifier V2 so that time-modulated pulses appear across the load resistance R3 and are applied to the grid of the first limiter valve V3. The anode of this valve is connected to the grid of a second limiter valve V4, from the anode of which the limited pulse output is taken. A variable bias for the valve V3 is developed across a resistance R6 which is the load resistance to a diode rectifier V1 fed by the incoming signal, the smoothing circuit R2, C1 having a time constant greater than the longest signal period. The valve V3 is thus biassed to an amount depending on the general signal level and on the noise interference. The difference in level between the limitations effected by the valves V3, V4 is predetermined by adjustment of the cathode resistance R8.

Abstract: 566,578. Prepayment mechanism for meters. BRITISH ELECTRIC METERS, Ltd., COOP, N. B., and WHITE, E. S. April 9, 1943, No. 5735. [Class 27] In prepayment mechanism for electricity &c. meters in which a price-change plate or disc n is employed, the coin pocket or holder a drives the index and prepayment spindle m through a friction ratchet clutch g, k which takes up the drive immediately without any play, a similar clutch being provided at k<1> between the spindle and a fixed part to prevent reverse movement of the spindle. Thus, the change-plate n can be adjusted to permit price changes in small equal amounts, such as by farthings per unit, without the use of change wheels or changespeed gearing. In the construction shown, the change-plate n has a stop o, the position of which determines the amount of rotation permitted the coin holder before the coin is discharged in the usual manner into the coin box. When a coin is inserted through a slot in the change-plate, it enters the coin holder a and rocks a lever b about its fulcrum c so that a tooth d on the lever engages in a slot e in a member f fixed to the wedge part g of the ratchet clutch. When the coin holder is rotated, the spring-loaded balls h couple the part g to an annulus k fixed to the spindle m and drive the latter.

A cam 39 follows the movements of the feeler arm 37 and causes longitudinal movement of the tappet rod 45 which bears against the free end of a brake shoe through a spring 47 which is thereby released in direct ratio to the change of tape roll diameter. The basic loading of the spring 47 may be varied by manipulation of a control knob 54 operating through a shaft 50 to move longitudinally of the rod 45 an abutment collar 46 mounted on the screw-threaded end of the rod 45. Tape from the roll 14 passes over a roller 36a of a tension gauge 36 to a guide roller 29 mounted in a bracket 27 capable of being accurately positioned by micrometer adjustment means 30. The bracket 27 is carried on a rod 26 movable by a wheel 32 to provide coarse adjustment for the guide roller 29.

Abstract: 494,942. Extrusion presses. WOLVERINE TUBE CO. March 2, 1937, No. 6217. Convention date, March 23, 1936. [Class 83 (iv)] In presses for extruding metal employing a punch the latter is capable of being moved to a position in which it is cooled by a device supported on one side of the punch and moved into axial alignment therewith. The punch and cooling device are capable of being moved axially relative to one another to surround the punch by the cooler. A punch B, Fig. 2, acts on a billet A forming a tube with a shouldered part which is severed from the tube by a cutter. The extrusion and severing mechanism are described in detail in Specification 494,941. The cutter is secured to an arm 34 mounted on a vertical shaft supported by a bracket 36 on a shaft 37. The shaft 37 is moved upwardly by a piston on a cylinder 39. A cooling device G is connected by an arm 50 to the arm 34 which latter is swung to position the cooling device with respect to the piercing punch B for cooling. The cooler comprises two telescopic units 51, 52 the outer unit 51 sliding vertically on the end of the arm 50 and the unit 52 being fixed thereto, and carrying a member 59, comprising two compartments 61, 64. A conduit 62 supplies the fluid to the chamber 61 which has apertures 63. A conduit 65 supplies the chamber 64 which has apertures 67. The cooling device is shown in Fig. 12 after swinging into alignment with the punch B while maintained in inoperative position by springs 53. When the shaft 37 is raised the lower end 26 of the punch B engages a saddle 68 to arrest the unit 51. The unit 52 moves up against spring action until the punches completely housed after which cooling medium is sprayed.
