Title: Improvements in or relating to methods of electropolishing, and the improved hollow stem valves having an electropolished internal surface
IPC: C25F3/16
Filed: 1944-03-14
Abstract: 611,609. Electrolytic polishing. THOMPSON PRODUCTS, Inc. March 14, 1944, No. 4720. Convention date, April 9, 1943. [Class 41] [Also in Group XXVII] The internal wall of a tubular metal member closed at one end, such as the stem of a hollow valve, is polished electrolytically to present a smooth surface free from any amorphous layer and having a high rate of heat transfer to the metal coolant such as sodium or copper, by allowing an electrolyte to flow into the member and overflow at the top, suitable electric current being passed through the electrolyte from the member as anode. A valve 13 is fixed vertically in a clamp 14 from which it is insulated at 17 and a hollow conductor 28 passes centrally down the valve stem through insulating spacers 30, 31 and clamp 29 which hold it respectively inside and outside the valve. An electrolyte, preferably a 75 per cent solution of orthophosphoric acid at 100‹ F. is passed from a reservoir (not shown) down the tube 28 and overflows, passing through apertures 33, 32 in spacers 31, 30. By positive connection 34 and negative connection 35 to valve 13 and conductor 28 these become anode and cathode respectively, a current passing between them through the electrolyte. If 2.5 to 3.5 amps. are passed for about 40 minutes with a cathode # inch diameter spaced #to # inches from the internal surface of the valve stem, the latter receives a mirror-like polish entirely free from the amorphous layer produced by reaming and abrading. Sulphuric and phosphoric acids and mixtures of the two are mentioned as possible electrolytes, while the valve may be made of alloys containing such metals as chromium, nickel, molybdenum, iron, cobalt and tungsten, such as those sold under the Registered Trade Marks " Nichrome," " Hastelloy," " Brightray " and " Stellite." The internal surface of the valve head may be polished by the use of an electrode extension such as that described in Specification 611,610.

Title: Improvements in radar systems
IPC: H01Q19/17
Filed: 1959-02-12
Abstract: 848,830. Directive radio systems. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Feb. 12, 1959 [Feb. 18, 1958], No. 4934/59. Class 40(7). An aerial system for a radar providing azimuth, elevation, and range information comprises a reflector P of part paraboloid form, asymmetric with respect to the axis VF and a plurality of primary elements S 1 , S 2 , S 3 -S n  arranged along a straight line Fy passing through the reflector focus F. If the point M, located at substantially the mid-height of the reflector, is the point which receives the greatest amount of energy from the sources S 1 -S n  then the line along which the primary elements lie should, according to theory, be the line Ft<SP>1</SP> parallel to the tangent Mt to the reflector at M. However, it is stated that it has been found that better results are obtained in practice if the line Fy along which the primary elements lie makes a small angle with the line Ft<SP>1</SP> as shown. Each primary element produces a single lobe radiation pattern and the strength of the energy fed to each may be controlled to produce a set of radiation patterns as shown in Fig. 2. These patterns give coverage in elevation from almost horizontal up to above 45 degrees and the strength of the patterns is graded so that their effective upper limit does not exceed a certain height. The sources may be fed from the radar transmitter by a single vertical rectangular guide fed at its lower end. This main guide may carry a T-junction adjacent each source at which a branch guide is coupled to the main guide by a diaphragm controlling the power passing and is terminated in a radiating source of small dimensions such as that described in Specification 838,287. Each branch guide is provided with duplexing arrangements so that radar echo signals received can be fed out to individual receiver arrangements. The receiving arrangements are thus each associated with a radiation pattern directed at a certain angle of elevation and, if the whole aerial system is scanned in azimuth, range azimuth and elevation information about objects can be determined.

Title: Improvements in pile collectors and delivery devices for printing and like machines
IPC: B65H29/34
Filed: 1923-02-20
Abstract: 211,703. Brecknell, H. E. F., and Brecknell, Munro, & Rogers, Ltd. Feb. 20, 1923. Delivery apparatus. - In pile collecting and delivery devices for collecting sheets of paper &c. from printing &c. machines of the type in which each sheet passes separately on to a receiving platform, adapted to provide momentary support, from which it falls on to a collecting platform where a batch of the required number is collected and dropped on to a delivery table, the receiving platform comprises one or more horizontally rotating sectors coacting with guides by which each sheet is located before falling on to the collecting platform, and the latter may comprises three, four or more horizontal angularly oscillating sectors which are actuated at the required moment to drop a batch of sheets on to a delivery platform. The paper &c. sheets are delivered by rollers k on to a receiving platform made up of two continuously-rotating sectors j, which are timed to occupy a position between the guides c to receive each sheet as it is delivered and then swing clear to drop the sheet on to a collecting platform. The receiving sectors are mounted on vertical shafts h provided with gear wheels o, one of which is driven from the main shaft q by a gear p and drives the other by means of a counter shaft rand gear wheels s. The collecting platform consists of four pivoted sectors m, normally positioned as shown in Fig. 2 to collect a pile of sheets thereon and adapted to be swung aside when the required number has been collected to drop the pile on the table b, the pile being then moved along the table by a pusher 3 moved along a slot 2 in the table. A transverse shaft t, driven by the main shaft q through a worm u, carries a chain wheel 4 and chain 5 passing round a chain wheel 6 on a shaft v, which is geared by gears 7, 8 to. a shaft w carrying a chain wheel 9 and chain 10 passing round a chain wheel 11 rotatable on a shaft x. The chains 5, 10 are thus driven in opposite directions and are provided with blocks 12, 13 adapted to engage the pusher 3 alternately and move it backwards and forwards. The collecting sectors m are geared together in pairs by wheels 16 engaging the gears n, and are actuated by a pair of racks 17 having pins 19 engaging slots 20 in operating levers 15 rigid with the shaft x. Also rigid on the shaft x is a trip lever 14 adapted to rock the shaft against the action of a spring 21. At the time when a pile of sheets of the. required number has been collected on the sectors m, the trip block 12 on the chain 5 engages the trip lever 14 and causes the levers 15 acting through the racks 17 to swing the sectors m from under the pile, which then falls on the table b. Almost immediately the block 12 slips over the trip lever 14 so that the spring 21 actuates the levers 15 in the reverse direction and returns the sectors m to position to collect the next sheet dropped from the receiving sectors j. The pile on the table b is moved aside by the pusher 3 engaged by the block 13 on the chain 10.
