Abstract: 266,047. Crockatt & Sons, Ltd., W., and Crockatt, W. C. Nov. 16, 1925. Resistances, measuring; liquid resistances. - Apparatus for indicating the presence of impurities in water or other fluids bv the variation caused thereby in their electrical conductivity has electrical means in the external electric circuit to permit alternation or adjustment to suit the condition of the circuit or the fluid under test. In the salinometer shown in Fig. 1 the liquid to be tested is passed through a pocket 24 having an inlet 25 and outlet 26 and a partition 27 acting as a weir to maintain the pocket 24 full. From the outlet 25 the liquid passes through the electrolytic cell 1, shown in detail in Fig. 2, comprising a cylindrical casing 2 with circular end members 3 of insulating material held in place by a screwed cap 5 and spaced apart by a glass or other member 6. In the centre of the end members 3 are located the electrodes 10, 11, which may consist, as shown in Fig. 3, of a base portion 53 of inferior metal having a head 54 over which is spun a thin sheet of platinum 56. The electrode fits, as shown in Fig. 2, into a counterbored recess having a ring of rubber &c. 59 to seal the space at the back of the head and prevent the electrolyte .from coming into contact with the base portion of the electrode. In the modified form of electrode shown in Fig. 4 a metallic member 64 passes through an ebonite tube 63 and has a head 65 carrying a piece of platinum wire 67, which is soldered in position and vulcanite &c. 68 is moulded over the end of the ebonite tube and vulcanized in situ. In a further modification, Fig. 5, a thin sheet of platinum 72 is held against a ring of rubber &c. 76 by a base 73 of inferior metal. The electrolytic cell is connected, in series with an ammeter 16, Fig. 1, graduated to show percentage of impurity in the fluid under test, to terminals 33, 37, which constitute variable tappings on a potentiometer resistance 20 connected to the supply mains. The instrument 16 is shunted by a resistance 43 having tappings 46 connected to conductors 47 extending into the bore of a mercury thermometer 22 so that portions of the shunt resistance 43 are cut out as the mercury rises in the thermometer, the bulb 23 of which is located in the pocket 24.

Title: Improvements in and relating to wireless aerial systems
IPC: G01S3/08
Filed: 1945-11-02
Abstract: 603,465. Aerials; radio direction-finding. ROCKE, A. F. L., REDGMENT, P. G., and WRIGHT, C. S. Nov. 2, 1945, No. 29088. [Class 40 (vii)] The aerial system for an Adcock-type direction - finder comprises eight vertical aerials 1-8 symmetrically arranged at the circumferential points of a Maltese cross pattern, eachpair of aerials 1-2, 3-4, 5-6, and 7-8 at the two circumferential points of each arm of the pattern being connected together and the mid-points of opposite connectors 9, 10 and 12, 13 being differentially connected. The Figure shows the invention applied to a goniometer-type direction-finder with the mid-points of oppositeconnectors joined through the field coils 11 and 14 of the goniometer but the invention is also applicable to a two-path cathode-ray tube direction-finder in which the two differential outputs are applied. to the X and Y deflection systems of the cathode-ray tube. In an alternative arrangement, Fig. 2 (not shown), the conductors 9-13 are replaced by pairs of radial conductors. The Specification gives a mathematical analysis showing that the octantal error of such a system is a minimum when each pair of aerials subtends an angle of approximately 60‹ at the centre, any residual error being much less than in the usual Adcock system so that aerial spacings of the order of the operating wavelength can be employed with a consequent increase in the signal pick-up or alternatively a given aerial system can be employed over a wider frequency band.

Title: Caging mechanism for gyroscopes
IPC: G01C19/26
Filed: 1952-11-18
Abstract: 729,946. Gyroscopic apparatus. BENDIX CORPORATION. Nov. 18, 1952 [Nov. 24, 1951], No. 29149/62. Class 97 (3). A gyroscope which comprises a rotor spinning in a case which is pivoted in an outer gimbal about an axis at right angles to the rotor axis and to the pivoted axis of the rotor case, has a caging mechanism composing members carried by the rotor case and outer gimbal and a single means movably mounted for engaging said members in succession to move the rotor case and outer gimbal to caged position, said mechanism including an electromagnetically operated actuating device operatively connected to said means for moving the latter into and out of engagement with said members to cage and uncage the gyroscope. In the gyroscope shown, the rotor 1 spins about axis Z in a case 3 pivoted on trunnions 7, 9 about an axis Y in an outer gimbal 5 which is pivoted on trunnions 11, 13 in a frame 15 about axis X normal to axes Y, Z. Trunnions 9, 13 carry cams 17, 19 having peripheral recesses 25, 27 adapted to be engaged by a cam follower 31 to hold the gyroscope in caged position. The follower 31 is spring urged at 58 away from the cams and is carried by a rod 32 pivoted in gimbal 15 and rotatable by axial movement of a plunger 37 of a solenoid 39 connected in parallel with a solenoid 55, both solenoids being connected in series with double throw-switches and a D.C. source (Fig. 3, not shown), one of which is manually operable while the other is operated by a latch 51 pivoted to a fixed part and to a spring-loaded plunger 53 of solenoid 55. With the switch arms in position to energize solenoid 39, plunger 37 is retracted to move follower 31 against the spring 58 to cage the gyroscope. Latch 51 moves under the action of spring 53 to engage a collar 52 on plunger 37 to maintain the gyroscope caged, such movement of the latch de-energizing the solenoid 39 by moving the switch arm of one switch to its other position. When the manually-operated switch arm is moved to its other position, solenoid 55 is energized to release latch 51 so that plunger 37 can move axially and the gyroscope become uncaged by the action of spring 58. Reference has been directed by the Comptroller to Specification 571,664.
Patent GB-681248-A (GB)
Title: Improvements relating to the reduction or prevention of corrosion of the bearing surfaces of lubricated mechanisms
IPC: C23C22/00
Filed: 1948-11-10
Abstract: Corrosion of the bearing surfaces of a lubricated mechanism is reduced or prevented by adding an aqueous solution of sodium nitrite to the water-immiscible lubricant in the lubricating system so that the solution is dispersed, but not permanently emulsified or dissolved, in the lubricant.  The process may be applied to machinery having a closed or forced system of lubrication, particularly where the possibility of water having access to the working parts exists. Thus the process may be applied to marine turbine installations where leakage of sea water into the oil system may occur.  The lubricant employed may be a straight mineral oil and the pH of the dispersion is preferably maintained between 6.5 and 9.  A wetting agent, such as sodium petroleum sulphonate or a sulphated secondary alcohol, may be added to facilitate the separation of the aqueous phase from the dispersion whenever it is desired to remove the aqueous phase, for example by means of a centrifugal separator. According to the Provisional Specification, corrosion inhibitors other than sodium nitrite may be employed.

Title: Improvements in or relating to electroplating apparatus
IPC: B65G49/04
Filed: 1948-11-10
Abstract: 686,664. Electroplating apparatus. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Nov. 10, 1948 [Dec. 11, 1947], No. 29242/48. Class 41. Electroplating conveyer apparatus comprises a plurality of movable supports for members to be electroplated by immersion in an electrolytic tank, means for moving the supports substantially continuously, and stationary conductor means disposed to be slidably contacted by the supports, the conductor means having alternate cathodic and anodic portions, whereby each movable support is rendered successively cathodic and anodic as it passes over the alternate portions of the conductor means. In the arrangement shown in Figs. 1 and 2, an endless chain driven by sprocket wheels 18, 20 is composed of alternate links 23, 24, the links 24 which are electrically insulated from each other, carrying movable supports 26 for racks 28 holding members 32 to be plated in a tank 10. The supports move in slidable contact with a conductor bar 38 formed with sections 39 electrically insulated from sections 40. The sections 39 are connected to the negative terminal and the sections 40 to the positive terminal of a continuous direct-current source of electric power. The tank 10 is provided with conductor bars 14 for supporting anodes 16. The spacing between the supports 26 is such that at any time a relatively constant number of the supports is in contact with the sections 40, most of the remainder being in contact with the sections 39, also the sections 40 are of lesser length than the sections 39. The members 32 are thus plated for short intervals and deplated for shorter intervals in alternate arrangement. In a modification a stationary anodic conductor bar and a stationary cathodic conductor bar are arranged sideby-side, each being provided on the upper surface with recesses with insulating material therein. The bars are engaged by a pair of spring-pressed contact brackets on each of the supports 26. In the arrangement shown in Fig. 5, a conductor bar 138 supported on the plating tank 130 by insulating brackets 144 is provided with alternate cathodic sections 139 and anodic sections 140 which are adapted to be engaged by loose copper support bars 146 carrying racks for the articles to be plated. The bars are placed in turn on an insulated portion 142 of the bar 130 and are moved across the bar by lugs 136 fixed to an endless belt 134. To enable an increased current density to be applied to the anodic sections of the conductor bar without altering the length of the conveyer an additional source of electric current may be provided and used in conjunction with a rectifier. Another arrangement, which enables the current to the anodic sections to be varied, involves the use of two variable resistances connected respectively in the circuits of the anodic sections and anode plates disposed within the tank. Specifications 630,165 and 642,101 are referred to.
