Title: Pressure equalizing valves in furnace charging apparatus
IPC: F16K47/08
Filed: 1977-02-21
Abstract: 1526624 Valves SA DES ANCIENS ETABS PAUL WURTH 21 Feb 1977 [8 March 1976] 07164/77 Heading F2V [Also in Division F4] A pressure equalization valve connecting the lock hopper of a high pressure furnace installation to a source of gas at a pressure approximating to that of the furnace, or to atmosphere comprises a movable housing downstream of the valve and means within the housing to divide the gas flow into a number of non-linear streams. This reduces the noise of the charging operations and reduces the wear on the conduits and/or hoppers. Each valve comprises a movable member 22 co-operating with a seating 26, and a housing 28 rotatable about a pivot 38. Replaceable perforated plates 30a, 30b and 30c are mounted within the housing 28 so that their perforations do not coincide. Since the housing may be readily swung about pivot 38 to allow access to the valve seat, or replacement of the plates 30, maintenance is simplified.

Abstract: 822,292. Applying mouthpieces to cigarettes. MOLINS, D. W., and MOLINS MACHINE CO. Ltd. March 6, 1957 [March 7, 1956], No. 7165/56. Class 130. Pushers 9a feed double-length stubs S in between alternate ones of cigarettes 2 on a conveyer 1 delivering to a platform 4 between which and a shoe 20 the cigarette immediately preceding each stub S is retarded to ensure its abutment with the stub, the operative pusher 9a being then retracted from the stub as the cigarette is gripped between a wheel 6 and a suction drum 5 feeding at the same rate as the pusher 9a but more slowly than the conveyer 1 which therefore, in conjunction with an even faster feed means in the form of a sponge rubber covered portion 21a of a roller 21, causes the cigarette immediately following the stub also to abut it, the resulting cigarette-stub assemblage passing to a conveyer 7 moving at the speed of the drum 5 and on which a gummed uniting band supplied by the drum 5 is folded and heat-secured around the assemblage which is then divided into two mouthpiece cigarettes. The stubs S are supplied along a guide 8 by an air jet. Each pusher 9a is rigid with a spring- loaded lever 16 pivoted at the free end of an arm 11 itself pivoted on a rotary disc 13, the members 11, 16 having rollers 14, 17 respectively controlled by a fixed cam 15 and a guideway 19 on the disc 13 so that during abutment of a stub with the preceding cigarette the pusher 9a moves in a straight path at constant speed, and so that during this period and that of subsequent retraction from the stub the pusher 9a remains parallel to the stub rear end. The shoe 20 is pivotally mounted and has a tail 27 spring-urged against a cam 28 which lifts the shoe clear of each stub and its following cigarette.

Title: Improvements in reversing gears
IPC: F16H3/00
Filed: 1931-03-11
Abstract: 363,567. Reversing - gearing. WESTERDAHL, W. 0., 3, Nybrogatan, Stockholm. March 11, 1931, No. 7540. [Class 80 (ii).] A container 15 is driven alternately in opposite directions from a driving-shaft 1 by means comprising a screw 23 of steep pitch on the driven shaft 12. Worm wheels 10, 11, which are driven in opposite directions from shaft 1 are each connected by a spiral clutch band 21 to a loose member 19 with a cone 17 within it fast on shaft 12. Upon the helix 23 is a nut 24 through a slot in which passes axially a dog-ended bolt 26. The reversals are effected by one or a pair of non-rotary nuts 31, 32 which engage a low-pitch screw on the outside of nut 24. The outer nuts 31, 32 move axially and each has a cam 33, 34 on its outer face. As shown, wheel 10 is driving shaft 12 through the coil clutch, the loose terminal member 19 of which is engaged by the end dog 27 of bolt 26. Main nut 24 turns solid with shaft 12 and the outer nuts screw along to the right until cam 34 is struck by a lug 36 on the right end of bolt 26. As lug 36 rides over cam 34, bolt 26 is withdrawn from clutch member 19 on the left, leaving that clutch to be disengaged by the spring coil. Main nut 24 continues to turn till it strikes the loose member 19 of the clutch on the right and until dog-end 28 of bolt 26 engages that member and winds the coil tight. The oppositely rotating wheel 11 now reverses the rotation of nut 24 and shaft 12. The outer nuts 31, 32 now screw away to the left to effect another reversal. The number of revolutions in each direction of container 15 is adjustable by adjusting the distance between the outer nuts, 31, 32. For this purpose, these nuts are formed as spur gears meshing with gears 37, 38 which are shrouded so as to slide laterally along with the nuts 31, 32. The gears 37, 38 are slidably splined on a shaft 41 and sleeve 43, respectively, which are normally locked together by a spring dog 50 and kept from turning by a crank 44 extending from the sleeve 43 into a strap 45 connected by a spring 46 to a fixed arm 47. To adjust the timing-mechanism, the strap 45 and dog 50 are disengaged and the crank 44 and a hand-wheel 42 are turned to bring the outer nuts, 31, 32 to the required relative position.

Filed: 1944-04-24
Abstract: 586,006. Variable-speed gearing. TRIGGS, W. W. (Gilbert & Barker Manufacturing Co.). April 24, 1944, No. 7588. [Class 80 (ii)] An epicyclic gear B carrying a driving shaft A is connected to an epicyclic gear E carrying a driven shaft F by two shafts C, D. The latter are interconnected by a variable-speed hydraulic gear G, control of which results in a variable speed to the shaft F in both forward and reverse directions. As shown, both gears B, E are identical, the planet pinions 2, 10 meshing with sun gears 5, 9 on the shaft C, and with toothed annuli 1, 8 on the driving and driven shafts respectively. The planet carrier 4 of the gear B has a gear 6 meshing a gear 7 on the shaft D, and the planet carrier 12 of the gear E has a gear 11 meshing with a gear 14 on the shaft D through an intermediate idler gear 15. The hydraulic gear G comprises vaned rotors 50, 51, on the shafts C. D, respectively, enclosed in a casing 26. The rotor chambers are connected by ducts 31, 32, and the casing 26 is adjustably mounted, as by a screw 28, in a fixed bracket 27. Axial adjustment of the casing 26 varies the capacities of the rotors 50, 51, and hence the relative speeds of the two shafts C, D.

Title: Improvements relating to hydraulic braking arrangements, particularly for motor vehicles
IPC: B60T11/22
Filed: 1953-03-19
Abstract: 724,568. Hydraulic brakes. DAIMLER-BENZ AKT.-GES. March 19, 1953 [March 19, 1952], No. 7687/53. Class 103 (1). In a hydraulic braking arrangement, particularly for motor vehicles, a master cylinder communicates with a storage vessel by way of a make-up cylinder provided with a piston subject to spring loading, and is characterized by the provision in the connection between the pressure space of the master cylinder and the make-up cylinder of a non-return valve which closes in the direction towards the make-up cylinder. When the brake pedal 14 is depressed, the piston 12 of the master cylinder 10 is displaced to the left, non-return valve 17 being closed to prevent any idle movement, and the brake fluid is forced out under pressure through a duct 11 into the operating cylinders to apply the vehicle brakes. Simultaneously with the displacement of the piston 12, the lever 24 is rocked by the rod 26 pivoted to the brake pedal 14, and the initially loaded spring 25 and consequently the piston 19 in the make-up cylinder 18 is displaced to the left against the action of the initially loaded spring 20. The port 27 to the storage vessel 28 is thus uncovered and brake fluid is drawn into the make-up cylinder 18. If the brake pedal 14 and piston 12 are then moved back into the inoperative position illustrated, brake fluid is drawn back from the operating cylinders into the master cylinder 10 and any loss of fluid is made up from the cylinder 18. The connection 27 for the storage vessel 28 is cut off and brake fluid in the make-up cylinder 18, the master cylinder 10 and the rest of the braking system is subjected to an internal pressure whose value is determined by the spring 20; the initial loading of which may be adjustable.
Patent GB-377189-A (GB)
Title: Process for accelerating chemical reaction between two or more gases
IPC: B01J19/08
Filed: 1931-03-12
Abstract: <PICT:0377189/III/1> <PICT:0377189/III/2> A process for accelerating the reaction between gases when reacting on each other without the aid of electrical discharges by intensifying the molecular intermixture of the gases comprises introducing carriers of electricity into one or other, or all, of the gases by known means in such a manner that they cause no chemical or molecular change in the gases and then subjecting the gases to the forces of attraction and repulsion of a unidirectional non-discharging electrostatic field of insufficient intensity to produce per se any electrochemical reaction between the gases.  The carriers of electricity may be produced in the reacting gases, or in an auxiliary gas, such as air, which is then mixed with the gases.  Charged liquids, sprayed through nozzles, or charged fine dust, and especially ions, are suitable carriers of electricity.  Ions may be generated by known methods, such as the primary or secondary action of X-rays, ultra-violet rays or radium rays &c. but preferably by impact ionization.  In the arrangement shown in Fig. 1, the two gases A and B enter a chamber 4 having plate electrodes 7, 7<11> set in insulating walls.  These electrodes may consist of thin aluminium plates, and the production of ions in the gases is effected by an X-ray tube 8 disposed outside the mixing chamber.  The electrodes 7, 7<11> are oppositely charged and cause a migration of the positive and negative ions produced in the two gases to the respective electrodes, thus effecting an increasing mutual diffusion of the gases into each other.  The reaction products issuing from the space 12 may be separated in known manner.  After a time, the polarities of the electrodes may be reversed, and so on, and in many cases, alternating current of the usual frequency may be used.  In the device shown in Fig. 3, the gases A, B, C and D are introduced into the chamber 17 by nozzles, and an auxiliary gas, such as air, charged with fine dust particles which are highly electrified by a corona discharge between the electrode 22 and the walls 20 of the vessel 19, is mingled with the gases A, B, C and D by means of a nozzle 23.  The electrostatic field is set up between an electrode 25 and the walls 28 of the chamber 17.  This electrode 25 may be designed as an ionizing or discharge electrode, and the addition of an auxiliary gas may be dispensed with.  Any resulting liquid or solid reaction products are deposited on the non-discharging electrode.

The container handling apparatus of the parent Specification, Fig. 1, is modified in that an elevator, Fig. 1, is coupled in to the conveying system to lift the containers from the lower to the higher conveyer for conveyance to a further work place. The apparatus of Fig. 1 is fed at its lower level by one of four endless conveyers in opposed pairs 11, 12, 11<SP>1</SP> (one of which is not shown), and at its upper level feeds out to one of four similarly disposed endless conveyers 13, 14, 13<SP>1</SP>. A container B delivered by conveyer 11 passes on to rollers 16<SP>1</SP> of a ramp 16 which is gravitationally tilted about 18 onto an abutment 58 whence the container rolls on to a roller surfaced support 24 co-plannar with the ramp 16. The support 24 is tilted by a pivoted lever 22<SP>1</SP>, 22<SP>11</SP> engaged by the tilting ramp. The support 24 is pivotable about either of two perpendicular horizontal axes 27<SP>1</SP>, 2711 against return springs 24<SP>1</SP>. A spring catch, Fig. 5 (not shown), locks the support 24 in the inclined position until the container B engages the lock to release it. A pair of endless vertical chains, 30, 31 are then started in motion and roller tipped levers 36, 37 mounted thereon engage and lift the container B from the support 24. Pivoted barrier levers 54 controlled by a roller 57 on each chain prevent premature delivery of the containers, on to the support 24. As the container approaches the top of the elevator, a support plate 40 carried on over a pair of arms 41 pivoted at 42 moves out under the container, under the control of a roller 60 on the chain 30, engaging the end of arm 41, and lifts the container clear of the conveying levers 36, 37. The plate 40 has a rollered surface and a universal mounting, similar to that of support 24 and the direction of tilt for delivery to one of the upper conveyers is controlled by latches 48, 49 which, when set, engage one side of the plate 40.
