Title: Treatment of articles in liquid baths
Inventor: HYAMS MONTAGU
IPC: C23G1/00
Filed: 1959-05-07
Abstract: Evaporation or other loss is reduced from the surface of an acid or alkaline bath into which metal articles are lowered for cleaning or coating by providing a layer of elements which float on the bath surface, present a surface of inert material compatible with the bath liquid, and readily separate about an article lowered through the layer and re-form the layer upon removal of the article.  Suitable elements have a surface of e.g. polythene, nylon, polyethylene, terephthalate, polyacrylonitrile or gelatine, filled with oil, grease or wax. Alternatively solid or cellular materials may be used by themselves, with an outer layer or as a part filling for the elements.  The largest dimension of the elements is preferably 0.25-1 inch, and their form may be spherical, rodlike, sac or mat.  In order to restrain movement, the elements may be joined together in chains or to form a net-like structure, and further may be attached to the sides of the bath.

Tyres, elastic, and tyre covers, tools for removing and replacing.-A hand-lever 4 carries arms 2, 3 and a presser-finger 6, the arm 2 being pivoted at the lever end, and the arm 3 and finger 6, at an intermediate point on the lever. Adjusting holes 9 are preferably spaced lengthwise of the lever 4, and the inner ends of the arms 2, 3 are bent to pass through the holes 9, being then detachably secured in position by wing-nuts. Spring washers may be interposed between the nuts and the lever 4. The outer ends of the arms 2, 3 are formed with hooks adapted to enter holes 17 in lugs 16 on the wheel rim, or brackets having perforated lugs may be clamped to the rim adjacent the rim ends. As shown in Fig. 7, the brackets comprise a body portion 21 having an apertured radially-projecting lug 16, and a clamping cheek 24 to engage the lip of the wheel rim, a screwed shank 26 carrying an adjustable clamping jaw 27. Legs 31, 32, one of which is made adjustable, may be formed on the brackets to contact with the inner face of the rim. In operation, the arms 2, 3 are inserted in the holes 9, 17 in the lever and rim respectively so that they take up positions as shown in Fig. 3, the hand-lever being then swung in a clockwise direction so that the finger 6 forces outwardly against one of the abutting end portions of the rim, he other rim end being moved slightly away circumferentially by the action of the pivoted arm 2. The hooks are then withdrawn from the holes 17, thereby allowing the rim ends to move inwardly and overlap. The arms 2, 3 are then swung over to opposite sides of the hand-lever to take up positions as shown in Fig. 5, the hooks being again inserted in the holes 17. The hand-lever is again swung in a clockwise direction, thereby causing the inner ends of the arms 2. 3 to cross each other, the outer hooked ends of the arms approaching closer together to contract and overlap the rim. When the hand-lever has been swung fully over, the pivoted arms contact with each other, and in their crossed position automatically lock the wheel rim in its contracted position.

Title: Improvements in or relating to direction finding radio receivers
IPC: G01S1/02
Filed: 1944-08-18
Abstract: 585,057. Direction-finding receivers. AMALGAMATED WIRELESS (AUSTRALASIA), Ltd. Aug. 18, 1944, No. 15859. Convention date, July 10, 1943. [Class 40 (v)] In a two-channel receiver for translating signals to a direction indicator, signal energy for monitoring is derived from radio-frequency energy by means of separate attenuation networks, each feeding a rectifier, one network with one rectifier being associated with each channel, and the outputs of the rectifiers are combined at a point where the radio-frequency energy has been 'substantially eliminated. Thus, by first building up signal voltages in each channel and then attenuating the feed to each rectifier, signals may be derived from both channels without the possibility of intercoupling and in such a way that regardless of the relative phase positions and amplitudes of the two desired signals, the-said signals will not cancel each other. As shown, the two channels are fed from the N, S and E, W elements respectively of an Adcock aerial system and their outputs are fed to corresponding N, S and E, W deflection plates of a cathoderay tube. In each channel radio-frequency energy from one pair of aerial elements is fed over the input 4 to a tetrode 3 coupled in resistance-capacity to a triode 7. The output of the triode 7 is fed through a transformer 9 of high step-up ratio, e.g. one to ten, to one pair of plates of a cathode-ray tube. The transformer 9 has a tuned secondary 10, the mid-point 11 of which is earthed. Energy for monitoring is fed from one side of the winding 10 to a diode rectifier 13 via an attenuation network comprising condenser 15 and resistor 16. Audio components appearing across the load resistors 14 of the rectifiers 13 associated with each channel are combined after elimination of the carrier frequency by filtering either directly or after amplification and are fed to a loud-speaker, after further amplification if necessary. For C.W. reception, a beat frequency oscillator 17 may be provided, the output of which is applied to the anodes of the rectifiers 13, a phase shifter 20 being included in one of the paths. In a modification, the attenuation networks, 15, 16 may be fed from the anode circuits of the valves 7 in which case a resistor 16 of lower value is employed. Specification 507,587 is referred to.

Abstract: 571,161. Hoppers. ROBINSON & SON, Ltd., T., and ORMEROD, H. Sept. 28, 1943, No. 15928. [Class 78 (i)] A pivotally mounted and counterbalanced hopper for feeding granular materials tilts when the weight of its contents is below a predetermined amount and renders inoperative one of the gears in the driving train of the discharge mechanism. The hopper a, Fig. 2, is pivoted at b in a larger hopper j which has a discharge roller h and gate k. The roller h is driven from a driving wheel i through gears f, g, the former of which is carried by a member d. This member is pivoted at e and is coupled to the hopper a by the link c. When the weight of material in the hopper is below a predetermined amount, it tilts to the right, and the consequent movement of the member d removes the friction gear f from engagement with the driver i. In a modification the hopper a, Fig. 3, is pivoted at b and connected by a link m to a counterbalanced member n which is pivoted at o and carries the shaft p of the feed wheel r. The shaft p carries also a wheel p<1> which, when the member n turns clock-wise, is put into frictional engagement with a driving wheel q. In a further modification (not shown) the hopper, feed wheel and its driving wheel form a unit which is carried upon a base pivoted to the machine frame.
