In a method of electro-depositing a metal, the plating current is controlled in dependence upon the polarization voltage of the cathode, i. e. the voltage difference between the cathode and electrolyte, e. g. by automatically controlling the plating current such that said polarization voltage is maintained constant. In the form shown an electroplating bath 8 having anode 6 and cathode 7 to which a D. C. plating current is supplied by means of an A. C. source 1, transformer 2 and rectifyer bridge 3 whose D. C. output is controlled by a regulator 4, is provided with a third or reference electrode which does not carry current and which takes the form of a metallic probe 9 immersed in the body of the electrolyte. The cathode 7 and probe 9 are connected via an amplifier 5 to the regulator 4 such that the D. C. output supplied to the electrodes 6, 7 is controlled with respect to the voltage difference existing between cathode 7 and probe 9. The method can be used to electro-deposit gold without codeposition of other metals, e. g. copper.

Abstract: 848,681. Digital data storage apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 20, 1956 [Jan. 6, 1956], No. 499/56. Class 106 (1). A signal storage device comprises a plurality of sets of switches, a set of prime movers corresponding to switches in each set of said sets and means for displacing said prime movers in order that they may successively actuate said sets of switches selectively in response to applied electrical input signals. As described, each set of switches consists of a column 11, Fig. 1, of four switches 11a, 11b, 11c, 11d, Fig. 2, of the type that once set remain set until reset, and the prime movers consist of a column of four arms 9a, 9b, 9c, 9d controlled by solenoids 8a, 8b, 8c, 8d, mounted on a rotatable cylindrical carrier 1. In operation the prime movers 9 are first positioned so that they co-operate with the first column of switches 11, the prime movers are selectively energized, by signals on leads 14 (which signals could originate for example from punched tape) to correspondingly position the switches in the first column 11. The cylindrical carrier 1 is then advanced to bring the prime movers into cooperation with the second column of switches and the prime movers are again energized to set the second column of switches. This is repeated until all the switches are set. At the end of each revolution of the cylindrical prime mover carrier the switches are reset by a set of four bars 12. Specifications 846,381 and 848,411 are referred to.

Filed: 1943-01-13
Abstract: 558,580. Screwing dies and die heads. MOREILLON, A. E. Jan. 13, 1943, No. 630. [Classes 83 (ii) and 83 (iii)] Concentric die heads comprise a ring shaped head 21, that may have handles 30 or may be mounted for use in a machine, in which substantially sector shaped dies 20 are mounted separated by replaceable distance pins 17 that determine the diameter of the thread cut. The dies are grooved on one face at 16 to engage the pins 17 and are circumferentially grooved at 18 to receive a spring retaining ring 19. The dies abut a flange 22 on the head and are closed on the pins 17 by a conical screwed ring 25, that may carry a spaced conically bored boss 31 to receive replaceable guide bushes 33. The dies may be produced from a disc by drilling and tapping a central hole and then turning the periphery into three eccentric segments. The die is divided between the segments and the dies when assembled with the segments forming part of the same circle have the threaded parts 11 eccentrically backed off. In a modification instead of eccentrically turning the periphery the disc is drilled also at 34 and the sections are placed in a jig with pins engaging the holes 34 and are turned so that faces engage abutments bringing the parts into the required eccentric friction. The periphery is then turned or ground concentric with the axes of the disc.

Filed: 1958-01-08
Abstract: 908,990. Testing and calibrating electric meters. SANGAMO WESTON Ltd. Jan. 6, 1959 [Jan. 8, 1958], No. 785/58. Class 37. An electric meter is tested and automatically corrected in testing apparatus of the general type disclosed in Specification 710,351, in which a calibration record is obtained on a paper strip 27, Fig. 2, by means of a printing bar 25 actuated at regular intervals by the watt-hour meter MT under test and a helical printing ridge 24 on cylinder 23 rotated under control of a standard meter. Two plates, 40, 41, Fig. 1, are rotated through friction clutch 43, the plates being insulated from each other and in slightly different angular positions. A striker-plate 44 drops when printing-bar 25 is actuated and makes contact first with plate 40, say, if meter MT is running slow, and then the plates 40, 41 are rotated together until both are in contact with striker 44. When striker 44 contacts plate 40, thyratron 45 fires and actuates pawl 51 to adjust the calibration control of meter MT through gears 52, 55, 57 and shaft 58. If the meter is running fast, pawl 53 is actuated and the adjustment is made in the opposite sense. The capacity of condenser 49 is such that only one pawl can be actuated at a time. When the meter is running accurately striker 44 contacts plates 40, 41 simultaneously and neither pawl is actuated, and detection of this condition may give rise to a warning signal so that another meter may be connected up for testing. Specifications 846,086 and 906,071 also are referred to.

Title: Improvements in methods of and apparatus for manufacturing rubberized fabric or the like
IPC: D06B23/14
Filed: 1929-01-10
Abstract: 331,594. Firestone Tyre & Rubber Co., Ltd., (formerly Firestone Tyre & Rubber Co. (1922), Ltd.), (Firestone Tire & Rubber Co.). Jan. 10, 1929. Resistances, measuring; wire resistances, threaded and enclosed.-In the manufacture of rubberized fabric by passing the fabric through a bath of rubber dissolved in benzol and drying in a chamber containing an inert gas such as carbon dioxide or producer gas, the proportion of producer gas to benzol is determined by submitting streams of the producer gas and of the gaseous content of the chamber simultaneously to a device for comparing their thermal conductivities. As shown in Fig. 1, producer gas is led into the chamber 1 from a pipe 12 in such quantity as to form a non-explosive mixture with the benzol vapour, the gaseous mixture passing out through a pipe 13 for recovery of the benzol. Producer, gas and chamber gas respectively are passed through branch pipes 14, 15 and closed chambers 19, 21 respectively, passing out through pipes 26 and discharging below the surface of water in a vessel 27, the level being maintained constant by means of a supply pipe 30 and overflow pipe 31. Before passing to the chambers 19, 21, the gases are passed through filters 16 and narrow orifice plates 17 so that the gases are freed from foreign substances and given a constant velocity with low pressure. The chambers 19, 21 contain resistances 25 wound through holes and across an aperture 24, Fig. 3, in a plate 23 of mica which is clamped between the halves 22, Fig. 2, of the chambers 19, 21 so that the gas passes across the resistance wire in its passage through the chamber. The chambers 19, 21 are surrounded by heating coils 36 in order to maintain their temperature constant. The resistances 25 are connected to form two arms of a Wheatstone bridge adjusted so as to be balanced when the proportion of producer gas to benzol is correct. Change in this proportion causes change in the thermal conductivity of the mixture, thus causing a change in the value of the corresponding resistance 25, and causing an indication of the galvanometer 35.

Title: Expandable manifold for water delivery system
Inventor: MILLER LEONARD L
IPC: F24D3/10
Filed: 1995-04-27
Abstract: A fluid delivery manifold (10) especially designed for water systems in buildings and residences is the subject of this invention. The manifold is formed from a plurality of identically configured fittings (12) provided with male and female ends (16 & 18) so that like fittings may be frictionally joined without the need for thermal welding. Retaining rods (60) extend the length of a gang of joined fittings (12) and are designed to provide compressive forces to maintain the fittings in sealing relationship. The fittings (12) are joined together in pairs which make an integral unit so that side-by-side hot and cold water manifolds may be presented in one assembly operation. The juncture between the integral pair of fittings is, however, designed to present a line of weakness (X) so that the two fittings may be separated if desired. Each fitting has three equal flat elongated surfaces which are disposed at 90 DEG relative to each other so that fittings may be joined in three different rotational positions.
