Title: Improvements in or relating to control systems for prime mover-electric power plant for winches, especially for use on trawlers
IPC: H02P9/00
Filed: 1946-04-15
Abstract: 610,699. Transmitting mechanical power. ANCIENS ETABLISSEMENTS BRISSONNEAU & LOTZ. April 15, 1946, No. 11516. Convention date, Nov. 12, 1943. [Class 38 (iv)] A winch is operated from a diesel or like engine working under constant torque conditions through a Ward-Leonard set 2, 7, the field 3 of the generator being supplied by an engine-driven exciter 6 and being supplied through reversing switches 4, 5, whereby the direction of rotation of the motor is controlled. Speed and power are varied by fuel control. The exciter characteristics are preferably such as to cause rapid decrease of resisting torque by the generator upon fall of speed of the prime mover, little or no excitation obtaining at idling speed. The motor has a separately excited field winding 8, in series with a resistance 12 which is varied in accordance with the winding radius of the cable to render the winding tension independent of the length of cable on the winch drum. Excessive tension when the load is overhauling is avoided by the insertion of a further resistor 121 in the motor field, under the control of a relay 21, 22, polarized by the motor volts. An oppositely polarized relay 14, also controlling the insertion of resistor 121 over its contacts 13, drops out when the motor holds the load, thereby closing a contact 15 in the circuit of a delayed action relay 16. The last changes over contacts 17-20 so that relay 14 is now energized from a separate source 28, the contacts 13 closing and permitting the motor to attempt to wind in cable with the resistor 12<SP>1</SP> short circuited.

Title: Indexing device
IPC: B23Q16/06
Filed: 1954-04-21
Abstract: 766,821. Metal-cutting machine details. CAPLIN, S. R. April 22, 1955 [April 21, 1954], No. 11532/54. Class 83 (3). [Also in Group XXIII] The cross-slide of a cutting or grinding. machine is traversed through a pre-set distance by the swinging movement of an operating lever 6 which co-operates with a ratchet-wheel 4 on the operating-shaft (e.g. the lead screw), of the cross-slide, by means of latches 22, 23, Fig. 5, engaging the ratchet-wheel to lock the lever to the latter against'relative movement in both directions, and when released allowing free movement of the lever relative to the ratchetwheel, rotation of the ratchet-wheel being restricted to one direction only. The lever can swing about the axis of the ratchet within limits determined by stops 8, 11 carried by a fixed plate 9, stop 11 being adjustable in an arcuate slot 12. The latches 22, 23 are pivoted spring- pressed pawls engaging opposite sides of the teeth of the ratchet. The pawl 22 has a fingergrip 28 to disengage it from the ratchet, and when so operated it disengages the pawl 23 also by inter-engaging formations 32 on the two pawls. The latches are held in this disengaged position by a spring-pressed latch 37 which, when the lever 6 is swung into contact with the stop 11, engages the latter to release the pawls for engagement with the ratchet. A spring- pressed withdrawable pawl 15 carried by the stop 8 prevents movement of the ratchet except in the direction from stop 11 to stop 8. Operation. The adjustable stop 11 is set to the position corresponding to the required amount of feed by movement of the lever between the two stops, the pawl 15 is engaged, and, with the lever abutting the stop 8, the pawls 22, 23 are disengaged by finger 28 and the lever then swung until it contacts the stop 11. The latch 37 then automatically releases the pawls for engagement with the ratchet and movement of the lever in the reverse direction rotates the ratchet through the required arc of feed.

Title: Manufacture of benzenesulphonamido-derivatives
IPC: C07D213/76
Filed: 1939-01-30
Abstract: 531,167. Sulphonamido compounds. SOC. OF CHEMICAL INDUSTRY IN BASLE. Jan. 30, 1939, Nos. 11606/40 and 11608, (both divided out of 533,495). Convention dates, Jan. 3, 1938, and Nov. 24, 1938. Sample furnished. [Class 2 (iii)] Benzene-sulphonamido-pyridine compounds containing in the p-position an amino group or a substituent convertible into an amino group are prepared by the methods known for the production of the corresponding compounds in which the pyridine residue is replaced by a hydrocarbon radicle. The convertible substituents consist of an acylamino, nitro, nitroso, azo or hydrazo group or a halogen atom. Thus, a benzene-sulphonic acid halide or ester, appropriately substituted, may be reacted with an aminopyridine; or the corresponding benzene-sulphonamide may be treated with a halogen-pyridine. When the p-substituent is one convertible into an amino group it may be so converted ; if an amino group is present, it may be substituted and comprise, for example, an alkylamino, N-acyl-N-alkylamino or aralkylamino group. Pyridine compounds mentioned are 2-, 3- or 4-aminopyridine, alkylaminopyridines, arylaminopyridines, aralkylaminopyridines, diaminopyridines, nitroaminopyridines, aminopyridine-carboxylic acids, 2-bromopyridine, 3-chloropyridine and 3:5-dibromopyridine. The products possess therapeutic properties. The preparation is mentioned of 2-(p-aminobenzenesulphonamide/-pyridine by reacting 2-bromopyridine with acetylsulphanilic acid amide followed by hydrolysis. A disclaiming reference is made to Specification 512,145. The sample furnished under Sect. 2 (5) consists of 2-(p-aminobenzenesulphonamido)- pyridine and is prepared by heating p-acetaaminobenzene-sulphonamide with 2-bromopyridine in the presence of potassium carbonate and copper powder and hydrolyzing the product with dilute caustic soda solution. The Specification as open to inspection under Sect. 91 also describes the preparation of analogous compounds in which the pyridine radicle. replaced by any heterocyclic residue other than a thiazole, and mentions aminoquinolines, amino-isoquinoli@es, amino-acridines and amino-oxazoles as amino-containing reactants. This subject-matter does not appear in the Specification as accepted. Specificatien 502,173 also is referred to.

Title: Improvements in or relating to automatic safety devices for preventing backward running of motor vehicles
IPC: B60T7/12
Filed: 1931-04-20
Abstract: 359,873. Vehicle brakes. FIAT SOC. ANON., 250, Via Nizza, Turin, Italy. April 20, 1931, No. 11641. Convention date, April 18, 1930. [Class 103 (i).] A device for preventing accidental reverse movement of a motor vehicle by means of a brake comprises a rocking lever 1 in contact with a rotating drum 31 operatively connected with the transmission, which lever during forward running is held in inoperative position by friction with the drum but on reverse movement is rocked by the drum in the opposite direction whereby the brake is operated. To bring the device into operation a foot lever 10, Fig. 1, is depressed to move the lever 1 axially against the edge of drum 31, Fig. 3, on a vehicle transmission shaft, by means of a rod 5, Fig. 1. Rotation of the drum during forward movement of the vehicle raises the lever but reverse movement lowers it to bring a toothed sector 2, Fig. 3, carried by the lever into engagement with a gear wheel 22 driven from the gear box transmission shaft 23 by means of a cone friction clutch 25. The lever 1 is thereupon further rotated and operates the brake shoes 30 by means of a link and levers. Depression of the foot-lever 10, Fig. 1, also moves a catch 11 into the path of the reverse speed control shaft 17 thus preventing engagement of reverse gear. Also when reverse gear has been engaged the shaft 17 prevents movement of the catch 16 and thus of the foot-lever for bringing the lever 1 into action. The lever 10 is provided with a pedal 11 having a spring catch 11a adapted to engage a stop 20 and hold the foot-lever in the depressed position. The lever 1 is rotatably mounted on the shaft 5 by means of a hub la and is capable of a slight axial movement on this shaft controlled by a spring arranged between a nut 7 on the shaft and the hub 1a and protected by a sleeve 4. The lever 1 is provided on its side where it engages the edge of the drum 31 with a friction strip 3. This apparatus may operate a wheel brake.

Title: Improvements in the catalytic oxidation of hydrocarbons
Filed: 1926-05-03
Abstract: 275,321. Marks, E. C. R., (Du Pont de Nemours & Co., E. I.). May 3, 1926. Oxygenated organic compounds; phthalic anhydride.-The catalytic oxidation of hydrocarbons in the gas or vapour phase is performed by passing a mixture of the hydrocarbon vapour with an oxygen-containing gas through a plurality of relatively small reaction zones arranged in a medium of high heat conductivity. The medium of high heat conductivity may be solid at ordinary temperature but liquid at the temperature of reaction, and the arrangement may be such that the reagents are preliminarily heated by the medium: suitable media are molten metals or fused salts, such as a mixture of sodium and potassium nitrates. Suitable apparatus comprises a number of catalyst-holding tubes 5 arranged in a casing 2 so as to be surrounded by a medium 5a of high heat conductivity. A pipe 1 passing through the casing 2 delivers the reagents to a header 3 having a curved surface 4, preferably paraboloid, whence the reagents are led through the tubes 5 to a condenser 7. The casing 2 is heated by a burner 9. Reference is made to the production of phthalic anhydride by passing a mixture of naphthalene vapour and air over vanadium pentoxide at 500‹ C.

Abstract: 781,213. Extruding alimentary paste, or clay or resin. BENEDETTELLI, A. April 22, 1955 [April 24, 1954], No. 11686/55. Class 87(2). Alimentary paste is passed into a vacuum chamber where mixing devices assist its deaeration and is fed thence to a plurality of discharge passages each housing a helical extension screw adapted to press the mix through an extruding die at the outlet of each passage, means being provided for driving a group of extrusion screws simultaneously. Water and flour or other mealy ingredients leave a measuring device 2 and pass through a series of mixing compartments 3, 4 and 5 with their vaned shafts 3, 7 and 8, and 9. The mixed paste is fed by a screw 18 to the inlet 19 of a vacuum mixing and distribution chamber 10, and the action of the screw 18 forces the paste through a perforated plate 20 with knives 21 moving across its outlet face, resulting in pellets of paste entering the chamber 10. The chamber 10 is subjected to vacuum by a pump (not shown), and the material is kneaded by vaned shafts 11, 12, 13, 14. The knives 21 are mounted on the shafts 12, 13. The pelleting and kneading under vacuum de-aerate the paste, after which it is forced through dies 23, each with its screw 22, into strings. The shafts 11-14 are driven through a gear train 16 by a motor 15. The drive for the shafts 6-9 is not shown. The screws 22 are driven in groups through worm gearing 26, 27, 28 by a motor 29. Each group may extrude the same or different length product ; different lengths are possible by variation of the extruder speed or the character of the extruder screw.

Title: Improvements in the manufacture and production of hydrogen
IPC: C01B3/46
Filed: 1937-05-04
Abstract: Hydrogen is obtained from solid, liquid or gaseous fuels by conversion with steam or mixtures containing mainly steam under conditions to give a gas containing 5-15 per cent of carbon monoxide and a residual content of combined carbon in the form of carbon dioxide, then washing out the carbon dioxide at ordinary or increased pressures, converting the residual carbon monoxide catalytically into carbon dioxide and hydrogen and if desired washing out this carbon dioxide.  The final product contains substantially no carbon monoxide.  According to examples, (1) brown coal briquettes are gasefied in a producer in which steam at 900 DEG  C. is introduced below the grate and a mixture of steam and oxygen is introduced about 1 metre above.  The gas produced contains 31,0 per cent carbon dioxide and 8,0 per cent carbon monoxide.  The gas is freed from tar, cooled and washed to remove carbon dioxide and hydrogen sulphide. Steam is added to the compressed gas, which is heated to 500 DEG  C. in a heat exchanger and led through a catalyst of magnesium oxide and zinc oxide.  The hot gas is cooled by washing with water, which may be used to add steam to the compressed gas above.  The final gas is washed to remove carbon dioxide, and the washing liquid may be regenerated; (2) waste hydrogenation gas freed from higher hydrocarbons is cracked with excess steam in a Cowper, and the cracked gas passed through a producer containing lignite coke. Carbon dioxide is removed by washing with alanine sodium salt and the residual carbon monoxide converted as in the first example, using a catalyst containing iron and chromium.
