Title: Improvements in or relating to rock-drilling plant and equipment
IPC: B25D17/16
Filed: 1944-09-18
Abstract: 585,480. Fluid -pressure servomotors. HOLMAN BROS., Ltd., and ORAM, M. Sept. 18, 1944, No. 17798. [Class 135] A valve device for controlling the air and water supplies to a rock drill so that the air supply is cut off if the water supply fails or falls below a predetermined minimum flow, comprises a selfcontained unit U having air and water inlets AI, WI and outlets AO, WO. A valve member H controls the air passage and is opened when the pressure in a chamber G behind it, communicated through a bleed port Q, is released by an auxiliary valve member E. The valve E is opened by the differential water, pressure on a piston valve member B produced by the flow past ports Y and through a bleed passage D against a spring C. Thus, the air valve is opened when a predetermined water flow is established, but if the flow fails owing to supply failure or a blockage at the drill, the air is automatically cut off to stop the drill. On the water flow being re-established, the air valve is again opened.

Title: Improvements relating to pulse-repeating circuits
Inventor: DRAKE BERNARD
IPC: H03K17/54
Filed: 1958-06-04
Abstract: 874,329 Pulse shaping circuits using thermionic valves; thermionic valve relay circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 5, 1959 [June 4, 1958], No. 17878/58. Class 40(6) In a valve relay and pulse shaping circuit which is controlled by an input pulse to be shaped, a limiting impedance is connected in series with the relay winding to limit current flow through it to a minimum value for consistent operation of the relay and a non-linear impedance having an inverse voltage-resistance characteristic is connected across the winding so that when the current through it decreases rapidly a low impedance shunt is connected across it thereby delaying its release. The Figure shows a valve relay circuit in which relay X has series-aiding windings X1, X2 energized by current flow through valve V which is controlled by a pulse applied across terminals IP so as to function as a pulse shaper and repeater an output pulse being derived by the operation of contact X1. In the absence of an input pulse, valve V is conducting and relay X is energized, the current flows through it being limited by resistor Rl to, for example, one and half times the test operating current of the relay. The relay X is shunted by a non-linear voltage-resistance element RX, for example a varistor of silicon carbide material, for instance that known by the Registered Trade Mark "Metrosil". When negative-going input pulses applied across terminals IP reach a predetemined amplitude, current flow in valve V is reduced and the relay X releases relatively quickly and when the amplitude of the pulse across IP decays below the level, valve X conducts fully again and relay X re-operates. Compensation for any distortion on the leading and trailing edges of the input pulse may be provided by the difference between the operating and release times of relay X. With large amplitude input pulses which cause rapid changes in the current in relay windings X1 and X2 the voltage surge thereby produced reduces the resistance of the non-linear element RX so that it acts as a low resistance shunt across the relay windings and delays the release of the relay X, thereby providing additional compensation for the distortion of the leading and trailing edges of the input pulse.

Title: Improvements in wrapping machinery
Inventor: ROSE ALFRED GERMAN
IPC: B65B57/14
Filed: 1948-12-16
Abstract: 665,611. Packing. ROSE BROS. (GAINSBOROUGH), Ltd. Dec. 16, 1948, No. 17956/48. Class 94(i). [Also in Groups XIX and XXX] In a machine for wrapping blocks or articles of friable material such as ice cream in which the articles are fed by a conveyer towards a transfer station at which they are transferred from the conveyer towards wrapping elements by a transfer member, a feeler member is arranged to move towards a surface of each article on the conveyer in turn so as to be arrested by the article, an abutment on a pivoted arm carrying the feeler member, being arranged on pivotal movement of the arm to move into or out of the path of a movable controlling member according as the article is of normal or abnormal thickness, the controlling member governing the transfer of the article to the wrapping elements. In the construction shown in Fig. 1, blocks 11 of ice cream are carried in pockets 12 carried by a conveyer chain 13. A feeler member 16<SP>1</SP> is carried by an arm 16 of a two-armed lever 16, 17 which is freely pivoted at 18. The arm 17 carries a cam follower 19 which co-operates with a cam 21, and carries an abutment 24. One arm 27 of a two-armed lever 27, 28 freely pivoted at 29, carries a cam follower 31 which is downwardly urged into engagement with a cam 32 by a spring 33. The arm 28 is forked at its outer end, the prongs being in alignment with lateral slots in tne pockets 12. The arm 27 carries an abutment 26. In operation, the feeler 16<SP>1</SP> moves down under the action of the cam 21, into engagement with the upper surface of a block of ice cream. lf the surface is normal, the position of the feeler 16<SP>1</SP> is such that the abutment 24 lies in the path of the abutment 26 when the lever 27, 28 moves clockwise and prevents it moving to ejection position. Otherwise the feeler 16<SP>1</SP> moves down further, and the abutment 26 is not impeded by the abutment 24. The lever 28 thus moves to its extreme right position and displaces the faulty block from the conveyer. The cams 21, 32 are arranged so that the feeler 16<SP>1</SP> commences moving upwards before operation of the ejector 28. Damaged articles may alternatively be carried on beyond the transfer station by the conveyer. The controlling member may operate through suitable electrical or mechanical delayed-action mechanism.

Title: Production of organic arsenic compounds
IPC: C07F9/80
Filed: 1943-11-05
Abstract: b -p-Arsonobenzoylpropionic acid is prepared by condensing a p-nitrobenzoyl halide with an alkyl ester of acetosuccinic acid in which the alkyl group contains from 1-3 carbon atoms, treating the resulting alkyl p-nitrobenzoylacetosuccinate with sulphuric acid, reducing the b -p-nitrobenzoylpropionic acid to the corresponding amino compound, and replacing the amino group by an arsonic acid group by the Bart reaction.  The b -p-arsonobenzoylpropionic acid may, if desired, be converted by reaction with hydrazine hydrate or with an alkyl or aryl substituted hydrazine into a 3-p-arsonophenyl-pyridazin-6-one. The condensation step is carried out in the presence of an alkali metal in solution in a medium in which the alkali halide is insoluble.  In examples: (1) ethyl acetosuccinate is added to a suspension of sodium metal in xylene, followed by a benzene solution of p-nitrobenzoyl chloride to give on removal of the impurities p-nitrobenzoylpropionic acid; (2) this is reduced with hydrated ferrous sulphate in the presence of ammonia to the corresponding p-amino-compound; (3) a hydrochloric acid solution of the amino compound produced in example (2) is diazotized and treated with arsenious oxide to form b -p-arsonobenzoylpropionic acid; (4) this compound is treated with an aqueous solution of hydrazine hydrate to form 3-p-arsonophenylpyridazin-6-one; (5) the product of example (4) is converted into its sodium salt by treatment with caustic soda; (6) 1-phenyl-3-p-arsonophenylpyridazin-6-one is prepared by treating b -p-arsonobenzoylpropionic acid with aqueous phenylhydrazine hydrochloride.
