Title: Prestretch fixture and combination thereof with drawing die press
IPC: B21D25/02
Filed: 1963-02-13
Abstract: 1,029,755. Cupping; stretch forming. CYRIL BATH CO. Feb. 13, 1963 [Feb. 14, 1962], No. 5844/63. Addition to 959.093. Headings B3E and B3Q. A prestretch fixture for a drawing press comprises units at opposite sides of the path of movement of the press ram and each including an elevator member movable generally parallel to said path and supporting a carriage carrying a gripper, the carriage being movable by a piston and cylinder in a direction transversely of said path to tension the work above its elastic limit before and during the drawing of the stock between the dies and the carriage being supported from the elevator member through angularly movable elements providing rolling contact or pivotal connection in the direction in which the carriage is moved to tension the work. Each fixture comprises a pair of identical units mounted between the male die and guide posts of an hydraulically operated drawing press and comprises a base 13 on which are mounted an elevator 20, grippers 30 and separator 50. The elevator 20 is raised by a pair of hydraulically actuated pistons 21 having their piston-rods pivotally connected to yokes 27 fixed to guide supports 14 which support upright guides 15 along which the elevator vertically moves. The grippers comprise a pair of reciprocable jaws 32 co-operating with cams 33, 34 and are actuated by three hydraulic cylinders 36 and heads 39 connected to the rear of the jaws. Each gripper is mounted on a carriage 50, which is attached to the elevator 20, and comprises two banks of three hydraulic cylinder assemblies 52 mounted in a pair of cylinder blocks 54 swingably attached at each end to trunnions 57. The pistonrod 61 of each assembly is pivotally connected to a pair of longitudinally extending rocking links 64 which are pivotally connected at their upper and lower ends respectively to the carriage 50 and pivots 65 mounted in fixed relationship to the elevator 20. The carriage 50 is supported on rollers 71 engaging trackways 70 in the elevator 20. In operation a metal sheet is stretched beyond its elastic limit by being gripped by opposing sets of jaws 32, and moving the carrier 50 outwardly under the influence of the cylinders 52 with or without movement of the elevator means to stretch the stock over the male die prior to drawing. Both units have independent hydraulic supply and control systems which permit the independent operation of the gripper, elevator and separator means, and are also independent of the operation of the main press. One or both units may be used to effect the stretching. The units and press ram may be controlled manually by remote control valves, e.g. solenoids and regulators.

Title: Improvements in or relating to drying-drums of drying apparatus
IPC: G03D15/02
Filed: 1961-02-17
Abstract: 917,379. Drying drums. GERSTER, H. Feb. 17, 1961 [Feb. 20, 1960], No. 5881/61. Class 98 (2). [Also in Group XIII] A drying drum 6 for drying photographic prints contains in its lower part a sump of heated liquid; disposed around the inside of the cylindrical drum surface, extending parallel to the axis, are a number of pockets 15 so shaped as to pick up liquid from the sump as the drum rotates. An endless band 10 of drying cloth bears against part of the drum, and prints to be dried are fed in between the band and the drum at the lower part of the apparatus, and emerge at the upper part. The liquid forming the sump may be water, and is heated by an immersed heater 19 controlled by a thermostat. As the drum rotates clockwise as seen in the Figure, the pockets 15 pass through the hot water, picking up some as they do so. The water is thus carried in the pockets until they reach their highest point, after which they empty themselves. The pockets may have small perforations, so that part of the contained water drains out as the pockets rise, thus varying the temperature gradient.

Patent GB-673142-A (GB)
Title: Improvements in tuning-indicator systems for tunable frequency-modulation receivers
IPC: H03J5/24
Filed: 1950-03-10
Abstract: 673,142. Valve circuits for radio reception. HAZELTINE CORPORATION. March 10, 1950 [May 28, 1949], No. 6078/50. Class 40 (v). In a frequency modulation receiver, in which the presence of a limiter renders accurate tuning by ear difficult, tuning is facilitated by controlling the gain of a stage subsequent to the discriminator by a voltage derived from the discriminator circuit, in such a manner that the output is a maximum when the set is correctly tuned. The amplifying stage 31 comprises a valve of the type with two control grids separated by a screen, the demodulated signals from the discriminator 19 being applied to the outer grid 33 over a blocking condenser 41 and volume control 35, and gain control voltages to the inner grid 34 over resistance-capacity filter 38, 39. The cathode circuit of the valve includes a resistance 40 of such a value that the gain of the stage decreases when a bias is applied to the grid 34, irrespective of polarity; negative bias causes the cathode current, and accordingly the transconductance to decrease, whereas positive bias increases the cathode current and hence the bias applied to the grid 33 from the resistance 40 in such a manner that the current to the anode, and accordingly the transconductance is again reduced. The discriminator 19 is of the phase-comparison type comprising a pair of diodes with separate, equal load resistances 22, 23, being so connected that when the set is accurately tuned the D.C. potentials across the loads are equal, so that the bias on the grid 34 of the amplifier is zero. Deviation from the correct tuning-point causes one or other potential to predominate, so that the gain of the stage 31 is reduced. Specification 673,141 is referred to.

Title: Improvements in and relating to the manufacture of remedies for certain infectious diseases
IPC: A61K35/14
Filed: 1937-03-01
Abstract: A remedy for diseases caused by cocci is obtained by treating albumen which contains blood corpuscles with natural or synthetic bile so that it becomes non-coagulable, adding a salt of a bile acid unless this is already present in sufficient quantity, and adjusting the pH value to between 8 and 14, preferably about 9. The albumen used may be human blood or blood cake, organs rich in blood, effusions or exudations from cases of ascites or pleurisy, lymphs or chyles.  The salt of a bile acid is preferably sodium taurocholate, but salts of glycocholic or cholic acid may be used, a suitable synthetic bile contains alkali salts of bile acids, lecithin, cholesterin, urea and uric acid.  The albumen may be treated with bile at about 37 DEG  C., preferably with addition of a disinfectant such as phenol, and the product is finally heated to a temperature above 100 DEG  C. to ensure sterility.  The liquid product may be added to a dilute solution of sodium taurocholate or, if sufficient salts of bile acids are already present, may merely be diluted, before adjustment of the pH value by addition of alkali.
