Title: Improvements in and relating to the conversion of polyphase currents into single phase currents
IPC: H02M5/48
Filed: 1931-05-08
Abstract: 375,029. Frequency changing ; phase changing. LÍBL, 0., 2, Neue-Bismarokstrasse, Hermsdorf, Berlin. May 8, 1931, No. 13656. [Class 38 (ii).] Polyphase current is converted into single phase current of lower frequency by transformers and rectifiers so arranged that succeeding phases of the polyphase current al, b1, cl, &c. have different amplitudes and the anodes of the rectifiers are rendered conductive in such order that a single phase current wave is built up in the load circuit as indicated by Fig. 1. Fig. 2 shows one arrangement in which a three phase network R, S, T supplies current to a pair of phase multiplying transformers P1, P2, wound so as to produce secondary phases of graded amplitudes. The secondary phases are associated with the anodes of a pair of rectifiers g1, g2 the circuits of which are completed at appropriate intervals by contacts on a switch drum h rotated synchronously with the supply current. The single phase load t is connected between the cathodes r1, r2 and the star points of the transformers so that one half cycle of the load current is derived from successively conducting anodes of rectifier gl, and the other half cycle from successively conducting anodes of rectifier g2. Other arrangements are described in whfch (1) the anode control switches are arranged between the secondaries of the transformers and the star points, Fig. 6 (not shown), (2) a single rectifier vessel is used with its cathode connected to the centre point of the primary of an output transformer, Fig. 5 (not shown), (3) the anode circuits are controlled by grids or ignition coils associated with separate rectifier vessels, Figs. 3 and 4 (not shown).

Abstract: 834,746. Engine starting mechanism. CATERPILLAR TRACTOR CO. April 30, 1958 [Feb. 17, 1958], No. 13691/58. Class 7(5) A starting mechanism for an internal combustion engine having a ring gear 15, Fig. 1, comprises a pinion 33 on a hollow shaft 35 for engagement of the ring gear and rotatable therewith, and control means starting engine crankshaft 14 and the pinion 33 including a spring-loaded normally engaged clutch 11 on a shaft 19, a disc-type brake 12 on a hollow shaft 25 axially movable on the shaft 19 and rotatable therewith, and control means actuated by a single lever 46 on a rockable shaft 43, Fig. 2, for sequential operation of disengaging the clutch, applying the brake and effecting engagement of the pinion 33 with the ring gear 15 by a single movement of the lever. As shown, the clutch plates 16, 17 are retained in engagement by springs 21 through a friction ring 20 to which are secured levers 23 which bear against a thrust bearing 24 on the shaft 25. The pinion 33 is mounted on a hollow shaft 35 and is driven through gearing from the shaft 19. A spring- lcaded control rod 38, slidable within the shaft 35 and secured to the pinion 33, is actuated by an arm 42 on the shaft 43 for engaging the pinion 33 with the ring gear 15, the pinion being retained in engagement by a spring - loaded latch 41 engaging a corresponding notch in the rod 38. A slotted arm 47 secured to the shaft 43 embraces a roller 49 supported in a bifurcated lever 50 resiliently connectea to a brake actuating lever 52 on a rockable shaft 31 having a yoke 30 thereon contacting the brake 12. On clockwise rotation of the lever 46 from the position indicated by broken lines, the shaft 31 and the yoke 30 are made to rotate anti-clockwise so that the clutch 11 is disengaged and the brake 12 simultaneously applied, whilst the arm 42 is rotated clockwise and contacts the rod 38 so that the pinion 33 engages the ring gear 15. The starting engine may then be started and the lever 46 rotated in a counterclockwise direction whereupon the brake 12 is released and the clutch 11 re-engaged whilst the arm 42 is rocked out of contact with the rod 38. When the engine reaches a predetermined speed centrifugal force will disengage the latch 41 and allow disengagement of the pinion 33 and the ring gear 15 under the action of a spring 40. In a modification, Fig. 3, an arm 47<SP>1</SP> on a rockable shaft 43 is connected through a resilient link 60 to a lever 52<SP>1</SP> mounted on a stationary shaft 31<SP>1</SP> and having an integral brake actuating yoke 30<SP>1</SP>.

Title: Improvements in or relating to methods of polishing metal surfaces in acid baths
Inventor: BINGHAM KENNETH CHARLES ARTHUR
IPC: C25F3/20
Filed: 1961-04-17
Abstract: <PICT:0940582/C3/1> An aluminium surface is galvanically polished by immerising it in an acid polishing bath at a temperature in the region of 100  DEG C. together with a spaced counter electrode directly connected to it by an electrical conductor. The spacing is such as to avoid gas streaking of the polished surface, e.g. 1 cm. A current of 3 amps may arise. The Figure shows Al plates 1, 2 held in a jig 3 of stainless steel and a stainless steel counter electrode 5 suspended in an acid polishing solution 11 at 98-100  DEG C. such as phosphoric and nitric acids or 77.5% phosphoric, 15.5% sulphuric, 6.0% nitric, 0.5% boric acids and 0.5% copper nitrate.  Following the polishing, the jig with the Al plates is removed from the polishing solution, rinsed in hot water, transferred to a 50% solution of HNO3 for 2 minutes and then washed first in cold tap water and then in isopropyl alcohol.  The plates are then dried and may be coated with a thin film of ferromagnetic alloy for use as part of a data store in a computer.  To polish both sides of an Al plate two counter electrodes may be used or for objects of more complicated shape a number of electrodes may be employed. The jig shown in the Figure comprises a bent rod 3 with turned over ends 4 forming a pair of tongs to hold the plate 1. The counter electrode 5 is welded to one arm of the bent rod and the other Al plate 2 is supported by a pair of jaws one of which 6 is welded to the counter electrode and the other 7 to the free arm of the tongs.  The lower end of the counter electrode has a perforated flap 8 forming a stirring paddle when the jig is moved by a rotating crank 1.  Brackets 9, 10 on the counter electrode help maintain the Al plates steady.

Title: Improvements in or relating to the construction of concrete piles
IPC: E02D5/42
Filed: 1933-05-11
Abstract: 413,101. Piles. NUTTALL, SONS, & CO. & J. MOWLEM & CO. (JOINT), Ltd., E., and JAPP, SIR H., 91, Ebury Bridge Road, London. May 11, 1933, No. 13763. [Class 68 (ii).] The metal reinforcement e of a concrete pile is lowered into a bore pipe a previously introduced into the ground and concrete is introduced into the pipe and subjected to hydraulic pressure, the pressure subsequently removing the pipe. The tops of the reinforcement are covered with steel tubes d which pass through a piston f. A cap j, Fig. 3, with a water inlet k is clamped over the pipe and water forced above the piston to consolidate the pile and subsequently remove the bore pipe. The latter is completely withdrawn by the reaction of a framework b, Fig. 1, within which the bore pipe is arranged between leaders o, a cross-head n pressing on the cap of the bore pipe and being held in slots p in the leaders by cotters q. The hydraulic pressure in the bore pipe raises the framework b, the plungers of the jacks s being in their lowermost positions. The pressure in the bore pipe is then released, the cotters removed and placed in a higher pair of slots, and the frame allowed to descend by releasing the jacks s. The pipe is thus removed in a step-by-step manner. The bore pipe may be removed in a continuous manner by connecting the cross-head to wire ropes which pass over sheaves at the top and bottom of the jacks s. In a further method of removing the bore pipe, a mandrel is forced on to the piston within the pipe, the latter being withdrawn by attached ropes passing over sheaves at the top of the frame.
