Abstract: 233,919. Marks, E. C. R., (Ingersoll- Rand Co.). July 3, 1924. Forging and sharpening rock drills; perforating by forging.-A device for piercing or clearing the bores of rock drills &c. as described in Specification 199,392, has a punch o, Fig. 4, actuated by a fluid-operated hammer-piston S striking one of two blocks a, c according as the punch is to be driven in or withdrawn, the device being fed towards or from the work-holding clamp g, Fig. 1, by fluid-operated means. The tool o is mounted in the block a which is connected by a cross-head b, bolts f, and cross-head d to the block c, these blocks &c. being free to move a small distance relative to the hammer cylinder P so that when this is fed towards the work the hammer S strikes the block a only, and when away from it the block c only. The control valve r, Fig. 4, is operated by a handle x, Fig. 1, and link 2 to admit fluid to the hammer cylinder and also a space u, Fig. 4, in front of a fixed piston p<1> so that the cylinder Q and hammering device carried by it advances along a guide L, Fig. 1. When the operation is completed the handle x is released and returned by a spring, causing fluid to be admitted to the space v and exhausted from the space u so that the device is withdrawn, while the supply of fluid to the hammer cylinder is not altered. This movement of the device brings the link 2 against a stop 10 which moves the valve into an intermediate position in which all fluid is cut off and movement ceases. The clamp g can be moved, by means of a bolt and slot k, into two different positions to suit drills or drill shanks. The device is shown mounted on a drill-sharpening machine F.

Patent GB-695332-A (GB)
Title: Improvements in and relating to clutch control mechanisms
IPC: F16H63/46
Filed: 1951-07-10
Abstract: 695,332. Operating clutches. BOCHORY, M. July 10, 1951 [Sept. 6, 1950; Nov. 29, 1950; Feb. 27, 1951], No. 16378/51. Class 80 (ii). Automatic clutch-operating mechanism for a motor vehicle comprises an engine-suction servomotor 2 with suction and air valves 12, 27 which are normally closed by springs and opened by solenoids 11, 17 controlled by the accelerator 44 and gear lever 55, the servo-piston rod having grooves of different lengths controlling switches 9, 9<SP>1</SP>, 9<SP>2</SP> so that the final phase of the clutchengaging movement is retarded, and means being provided whereby, if the accelerator is depressed abruptly, this final phase of engagement is accelerated. As shown, these means comprise a switch 34 controlled by a spring-loaded diaphragm 30 subject to engine suction so as to be closed only on abrupt depression of the accelerator. The switches 9, 9<SP>1</SP>, 9<SP>2</SP> correspond to switches 50, 62 and 52 in the gear box which are closed when first or reverse, second, and third or fourth speeds are engaged. A switch 39 is closed when the accelerator is released, a switch 10 is opened when the suction valve 12 is opened, and a speed-responsive switch 53 opens above a predetermined speed. On release of the accelerator 44, so long as the predetermined speed is not exceeded, the solenoid 11 is always energised via switches 39, 53 and opens the suction valve 12 to cause clutch disengagement. Similarly, if the gear lever 55 is moved to neutral, solenoid 11 is always energised via switch 51 in the gear box, to cause clutch disengagement. When a gear, for instance first gear, is engaged and the accelerator is depressed (or held released if the predetermined speed is exceeded), the circuit through solenoid 11 is broken, valve 12 and switch 10 close, and solenoid 17 is energised via switches 10, 9, 50. Air valve 27 is thus opened and air has free access to the servo from a filter 28 through chamber D<SP>1</SP>, port 16b and chamber C'. The clutch moves rapidly towards engagement until switch 9 is closed by its groove. Valve 27 now closes and the final engagement is completed under the control of an adjustable bleed opening 16c. If, however, the accelerator is depressed abruptly, so as to reduce the suction effect, with third or fourth gear engaged, switch 34 closes and solenoid 17 is energised via switches 34, 52, thus by-passing the switch 9<SP>2</SP> and maintaining the air valve 27 open during the whole engaging movement. The switch 34 may, however, co-operate also with the other gear switches 50, 62. Instead of operating the switch 34, the diaphragm 30 may operate to open an additional air bleed valve, for speeding up the final engaging movement; or the switch or valve may be operated directly by the accelerator. Alternatively, in addition to the permanent adjustable air bleed opening 16c to the servo, there may be a permanent adjustable engine-suction bleed entry to the servo. Specification 683,049 is referred to.

Title: Primary galvanic battery and method of making same
IPC: H01M6/48
Filed: 1954-06-03
Abstract: 739,990. Batteries. UNION CARBIDE & CARBON CORPORATION. June 3, 1954 [June 12, 1953], No. 16399/54. Class 53. The nested trays 10 of a stack of seriesconnected cells are each provided with an outwardly flared portion 11 and are made of a thermoplastic material in a strained condition made, for example, by warming and stretching a tubular band of the material so that when cooled the portions 11 retain the shape shown in Fig. 2. The stacked cells are placed under compression and immersed in a warm bath of a sealing compound consisting of a soft wax or grease of a kind that remains soft indefinitely on cooling. The sealing compound enters the gaps between the edges of the trays and the heat of the bath causes the flared portions 11 of the trays to return partly to their original unstrained shape, a thin layer of the compound being retained between the overlapping portions of the trays as shown at 20 in Fig. 1, The stack is removed from the bath and tapes 36 applied to maintain endwise pressure. The seals 20 prevent loss of moisture from the cells but excess gas pressure causes the seals to yield to allow gas to escape after which the seals close again. The battery may be provided with a hard wax coating 38 and with end terminals 24, 34.

Abstract: 292,163. British Thomson-Houston Co., Ltd., (Assignees of Langmuir, I.). June 16, 1927, [Convention date]. Low-pressure metallicvapour apparatus. - In order to prevent, in a vapour rectifier, back arcing caused by the bombardment of a negatively charged anode by positive ions, the anode is provided with a nozzle having its narrow end projecting into a concave surface formed in the anode, a shield being provided to surround the anode and the nozzle. In the form shown in Fig. 1, the anode 1, formed with a concave surface 2, is supported in the casing 3 by insulators 4, 5 and is connected to a lead 7 by a flexible connection 8 passing through a glass cylinder 6. Supported between the insulators 4, 5 is a shield 9 extending into the evacuated casing 3 and serving to protect the anode from the hot mercury vapour projected from the cathode. Supported by an insulator 11 from the shield 9 is a nozzle 10, the contracted end of which projects into the concave surface of the anode, the curvature of the surface being such that the positive ions formed on the anode are discharged into the nozzle and are carried away by its walls. Control of the potentials of the shield 9 and nozzle 10 is effected by means which include conductors 12, 12<1> passing through insulated bushings. In a modification, the nozzle is not insulated from the anode shield, and the anode may be spherical in form. In a further modification, the nozzle is separated from the concave anode surface by an insulated conductor supporting a grid or control electrode which is connected to an extended lead passing through a glass seal. Specifications 253,126, 261,763, and 261,768 are referred to.

Title: Improvements in or relating to a process for the production of aliphatic anhydrides
IPC: C07C51/235
Filed: 1950-07-03
Abstract: Anhydrides of aliphatic acids of 2-4 carbon atoms are made from the corresponding aldehydes by a continuous process which comprises introducing aldehyde to be oxidized and gas containing oxygen into a body of liquid comprising the anhydride to be produced, the corresponding acid, the corresponding aldehyde, at least one catalytic salt, and, in an amount of at least three quarters of the total weight of the body of liquid, a diluent or mixture of diluents having a boiling-point above 200 DEG  C., which is liquid and chemically inert at the reaction temperature, which neither dissolves in nor is miscible with water, is miscible in all proportions with the anhydride to be produced and at the same time with the corresponding acid to give a mixture capable of dissolving the catalytic salt in the proportion of its use, said body of liquid being maintained at a temperature at which oxidation of the aldehyde to the anhydride occurs, and the rate of supply of the oxygen-containing gas being such that the formed water, anhydride, and acid are continuously entrained from the body of liquid by the gas leaving said body.  The temperature of reaction may be 40-100 DEG C., and the partial pressure of oxygen in the gas blown into the liquid may be below 76 mm.  The concentration of the aldehyde may be 3-5 per cent, and the catalyst may be a salt of copper, cobalt, nickel, vanadium, or silver and the acid corresponding to the anhydride being produced.  Diluents specified are butyl, allyl, or amyl benzoate, dimethyl or dibutyl phthalate, dibutyl maleate, butyl stearate, glycerol tributyrate, tributyl phosphate, o-tolyl benzoate, tributyl borate, tetrahydrofurfuryl benzoate, citronellyl acetate, ethyl phenylacetate, diethyl dibromomalonate.  The gas and vapour issuing from the body of the liquid may be cooled to condense the vapours, a part of the residual gas being recycled and the remainder washed with a solvent and rejected.  The last-mentioned solvent charged with substances extracted from the issuing vapours may be treated with fresh oxygen containing gas which thereafter passes to the reaction.  The arrangement may be such that this solvent is relatively cold for washing the issuing vapours and relatively hot during contact with fresh gas.  Examples are given of the preparation of acetic anhydride using diluents and catalysts from among those specified above, or mixtures thereof.
