Title: Improvements in or relating to rotary steam drums
IPC: D21F5/10
Filed: 1926-03-13
Abstract: 265,025. Millspaugh, W. H. March 13,1926. Discharging.-For discharging the water of condensation, a rotary steam drum, used as a drier in paper or textile manufacture, has an evacuator consisting of a conduit with a curved scoop adjacent the drum to convey the water to a hollow shaft. Ends 11 are secured to the drum 10 by hooked bolts 12, and the drum is strengthened by conical members 18, which have flanges 19 bolted to a spider 22 at the centre of the drum. The ends 25 of the conical members are bolted to the end plates 11. The evacuation shown in Figs. 1 and 2 consists of a hollow arm 40 supported loosely on one of the conical members 18 and maintained in a vertical position by a weight 42. The arm 40 has a flared mouth or scoop 44, which may be sufficiently wide to reach to the stiffening spider 26. The drum is rotated at high speed and steam is admitted through the hollow shaft 15. The steam passes through holes in the shaft and the conical members 18 into the drum. The condensed water is thrown, by centrifugal force, to the wall of the drum and is collected by the scoop 44, from whence it passes through the arm 40 and openings 46, 47 in the members 18, 15 aa these come into register with the arm once in each revolution.

Title: Mass flowmeter
Inventor: STERLING JOHN JEROME
IPC: G01F1/696
Filed: 1968-02-13
Abstract: 1,212,071. Measuring mass flow rate electrically: venturi apparatus. TECHNOLOGY Inc. Feb. 13, 1968, No. 7078/68. Headings GIN and G1R. The mass flow rate of a fluid through a conduit is determined by a thermistor in the flow path fed with a constant current, so that its temperature is raised by the heating current and lowered by the fluid flow, the resultant temperature, as determined by its resistance, being indicative of the mass rate of flow of the fluid. The circuitry incorporates electrical means for automatic compensation for variations in ambient temperature of the fluid, and mechanical means for ensuring laminar flow of the fluid. As shown (Fig. 1), a thermistor 31, located in the flow path of a fluid through a conduit 16, is fed with a constant current from a source 22. The ambient temperature of the fluid is sensed by a second thermistor 60. The voltage across thermistor 31, as modified by the voltage across the compensating thermistor network, is measured on leads 62, 64 and is indicative of the mass flow of fluid through the conduit. The adjusting procedure to obtain full compensation for the ambient temperature of the fluid is described. To remove irregularities in the flow pattern of the fluid through the conduit, a foraminated screen is placed across the inlet, and the internal crosssectional shape is suitably tapered (Figs. 6-15, not shown). The foraminated screen may comprise a body of porous metal or foam metal to reduce any temperature difference between the fluid and the conduit. In one embodiment Fig. 14, the fluid enters conduit 180 at 182, passes over a conical shield 184 and through a series of holes 190 in the flange 188, and follows the arrows through a foraminated body 198 to outlet 183 passing temperature sensing elements 212, 214.

Title: Process for the production of substituted triazines
IPC: C07D251/26
Filed: 1958-03-05
Abstract: The invention comprises 1,3,5-triazines of the general formula <FORM:0889715/IV (b)/1> which are substituted in the 4- and 6-positions by isothiocyanate or thiocyanate groups or in the 4-(or 6-) position by a thiocyanate or isothiocyanate group and in the 6- (or 4-) position by the group -XR, in which formula the radicals R, which may be the same or different, represent aliphatic, araliphatic or cycloaliphatic radicals which may, if desired, be substituted and which can also contain one or more hetero atoms, and X represents oxygen, sulphur, an NH group or -N= group or a direct carbon-carbon bond, or where only one group -XR is present then -XR may represent an alkoxyarylamino radical.  The novel compounds may be made by reacting a 2-(RX-substituted)-4,6-dihalotriazine or a 2,4-di(RX-substituted)-6-halotriazine with the thiocyanato salt of an alkali or alkaline earth metal or zinc in the presence of an aliphatic alcohol containing from 1 to 5 carbon atoms as solvent. The alkoxy-substituted isothiocyanato or thiocyanato triazines may also be made by reacting a 2,4,6-trihalotriazine with the cyanato salt and the aliphatic alcohol.  Instead of the thiocyanato salt, a reaction product of a salt of hydrocyanic acid with elementary sulphur may be used.  Examples describe the preparation of 2,4-dithiocyanato-6-methoxy-s-triazine 2,4-dithiocyanato-6-phenetidino-s-triazine and 2,4-dimethoxy-6-thiocyanatos-triazine.  The products are useful as chemical intermediates and pesticides.

Title: Improvements in and relating to the manufacture of laminated springs
Inventor: COTTAM BASIL RIDER
IPC: B21D53/88
Filed: 1957-03-05
Abstract: 827,675. Angular bending. COTTAM & CO. Ltd., E. March 4, 1958 [March 4, 1957; Aug. 1, 1957], Nos. 7152/57 and 24439/57. Class 83 (4). A method of bending plates for semi-elliptic laminated springs includes, for each individual plate, bending a plate blank, in heated condition, in two stages between the same pair of relatively movable dies having mating concave and convex surfaces, in the first stage the plate being contacted throughout substantially the whole of its length by the opposing faces of the dies and bent to a preliminary degree of curvature and in the second stage being contacted at spaced points intermediate its ends to bend the blank within a medial length thereof to a predetermined and more sharply inflected curvature. The convex die 11 has medially of its length a plunger 17 spring-urged outwardly an adjustable amount and has at its ends pawls 27 for positioning the ends of the blank during bending. The concave die 12 comprises a centre block 30, top and bottom plates 28 and arms 34, pivoted at 31 to the plates 28 and extending therebetween. The arms 34, which are urged outwardly by a spring 36 operating through adjustable links 37, each carry U-shaped elements 35 which bear on a resilient former plate 38 adjustably pivoted at 41 to the block 30. In operation a heated plate blank is placed on the die 11 and located thereon by the reduced end of the plunger 17 engaging a hole in the blank. The die 12 is then moved horizontally along a bed 10 towards the die 11 to bend the blank there between, the plunger 17 and arms 14 being moved back against their springs. The die 12 is then withdrawn, whereupon the springs push the plunger 17 and the elements 35, and thus the ends of the former plate 38, out to further bend the blank. To bend shorter blanks, a shorter plate 38 is used and the elements 35 are positioned nearer to one another. The die 12 may alternatively have spring-loaded die elements which engage the blank directly and which comprise plungers moving in pockets in the die 12 or slidable along yieldable arms in the die 12. The dies may operate in the vertical plane.

Title: Improvements in gear pumps
IPC: F04C2/14
Filed: 1939-03-04
Abstract: 525,986. Gear pumps ; stuffing boxes. EGERSDORFER, F., and EHRICH & GRAETZ AKT.-GES. March 4, 1939, No. 7187. Convention date, March 4, 1938. [Classes 110 (ii) and 122 (v)] In a twin type pump, gears 5, 6, 7, bear against bushes at one end, and a plate 12 of hard steel, or the like, at the other. The casing 1 and cover 13 may be made of light metal. The driving shaft 14 is provided with a collar 19 between two packing washers 20. Radial bores 22 admit fluid being pumped to all surfaces exposed to friction, for lubricating purposes. Suction ports 23, 24 communicate with axial bores 25, 26, which are normally closed on the side adjacent the cover 11 by spring-pressed valves 33 leading to two channels 35. Bores 29, 30 communicate with the pressure side of the pump. Fluid may be pumped through the byepass 35 thus formed directly to a receiver, e.g. a carburetter, by external means such as a hand pump. Pressure chambers 27, 28 communicate with bores 29, 30, and delivery is past valves 37. A pressure gauge may be connected to a port 40. The bores 29, 30 lead to a central delivery pipe 41. Spring-pressed control pistons 46 are placed in bores 43, 44, which on their upper side, Fig. 2, communicate through passages 49 leading to the compressor pipe delivering air to the engine which is being supplied with fuel by the gear pump. In the case of the engine'not being super-charged the chambers 48 are open to the atmosphere. When the pressure in chambers 35 rises above a predetermined level the pistons 46 are lifted to open a byepass leading to the suction side of the pump by way of annular spaces 51 which communicate with bores 25, 26. Inclined slits 52, provided in sleeves 45, cause a larger or smaller cross-section to be exposed by the pistons depending on their adjustment. The pistons may be caused to rotate by means of a pin 54 which projects into a helical groove 53.

Title: Improvements in electrical plug and socket connectors
IPC: H01R13/20
Filed: 1942-05-27
Abstract: 561,043. Two-part couplings., MODREY, H. J. May 27, 1942, No. 7189. [Class 38 (i)] The members of a plug and socket coupling are locked together by a clamping' bar having a head which, when the plug member is released after insertion, engages a hole in the socket member, in the manner described in Specification 553,623, [Group XXII]. In one form, a contact pin 9a lying alongside the clamping bar 8 protrudes through a metal plug 7 in a hollow body 6 and is attached to the lower end of a spring 9 within the body. The bar 8 is attached to a metal cap 5 or to a plunger 5a, Fig. 2, secured in the metal cap 5 and resting upon the spring 9 and to the cap a lead 4 is connected. When the cap 5 with its insulating housing 1 is pressed down, the bar 8 protrudes further so that its head 8a is clear of the pin 9a and can be passed first through a hole 11b in the disc contact 11a of the socket 10. The pin 9a and the shank part of the bar 8 follow into the hole 11b and substantially fill it, so that when the plug is released and the bar 8 is drawn back by the spring, the head 8a is pressed against the underside of the disc 11a and prevents withdrawal of the contact. A bayonet catch 1a 6a may be provided to hold the parts in position during insertion of the plug. Where additional connections are required, washers 12 attached to leads are inserted between the plug 7 and the disc 11a. In a modification, the disc may have upstanding resilient claws to grip the protruding end of the plug 7. Where two contacts similar to that above described are mounted on the plug body, a single depressible cap carries the two plungers 5a. Where the fastening device .does not constitute a contact, or only an earthing contact, it is arranged between-a pair of flat contacts that abut resiliently against studs in the co-operating member. Instead of depressing a cap to compress the spring, the plunger 5a may be actuated by a press-button.

Title: Circuit arrangements for limiting testing time of selectors in telecommunication installations
IPC: H04M3/12
Filed: 1953-03-16
Abstract: 727,533. Automatic exchange systems. SIEMENS & HALSKE AKT.-GES. March 16, 1953 [March 14, 1952; March 14, 1952], No. 7235/53. Class 40 (4). In a system in which a selector is stopped on an idle outlet when a discharge tube conducts, the discharge tube is enabled by a potential applied momentarily under the control of the selector or its driving mechanism when the selector reaches each outlet and at a time such that a successful test at one outlet cannot be too late to prevent the selector moving to the next. In a selector RW similar to that described in Specification 712,013, in which the outlets are characterised by different recurring series of pulses P1, P2, P3 and the pulses are connected to the grids G1, G2 of the gas discharge tube RO1 over a digit switch MW and a control wiper d of the selector respectively, the application of the potential denoting an idle outlet to the cathode together with the simultaneous presence of pulses at the grids G1, G2 is not sufficient to fire the tube RO1. The selector RW is driven alternately by two magnets M1I, M2I connected up by contacts m1 m2 actuated at each step. The energization of one of the magnets momentarily induces a potential across its second winding M1II, M2II which is applied to grid G1 and enables the discharge tube RO1 which if the selector is at an idle wanted outlet fires. The rise in potential of the outlet connected to wiper c as a result of RO1 passing current busies the outlet. Discharge tube RO2 ignites to bring up P which energizes both magnets M1I, M2I to stop the selector and earths wiper c to finally seize the outlet. In a modification the windings of the switch magnets providing the enabling potential are connected between the cathode of discharge tube RO1 and wiper c. In a further modification the magnets have one winding only and the energizing circuits of the magnets are connected over condensers to a third grid of the discharge tube RO1 to provide the enabling potential. Instead of deriving the enabling potential from the magnets, the potential may be applied over contacts operated by movement of the selector.
