Abstract: 240,444. Meyer, F. Sept. 29, 1924, [Convention date]. Void [Published under Sect. 91 of the Acts]. Stoppers with valves.-Liquids which are capable of dissolving large quantities of carbondioxide, are discharged from a vessel and atomized on the operation of a valve, by the pressure of dissolved carbon dioxide. Fig. 1 shows a bottle C provided with a rubber stopper V through which passes a spray tube L the lower end of which is bent to bear against a portion of the stopper. When liquid is to be sprayed the bottle is tilted and the tube L turned to allow liquid to be forced through it under gas pressure. Fig. 2 shows a form in which a tube L' passing to the bottom of the vessel is mounted in the stopper and the tube L bent so that its inner orifice normally bears against the stopper. In a modification, the tube L is closed at its lower end and provided with a lateral hole so that in rotation it establishes communication with a transverse bore in the stopper into which the upper end of the tube L<1> opens. The tube L, Fig. 4, is open and communicates with a transverse bore in the rubber stopper V while the tube L' has a lateral orifice which, on rotation of the tube by a handle, also communicates with the transverse bore.

Filed: 1969-05-07
Abstract: 1,271,104. Vinyl acetate. FARBENFABRIKEN BAYER A.G. 7 May, 1969 [10 May, 1968], No. 23224/69. Heading C2C. In a process for the purification of crude vinyl acetate containing acetic acid, water and ethyl acetate by azeotropic distillation of the vinyl acetate and water as the head product, and phase separation of the condensate, the vinyl acetate of this condensate is partly recycled to the azeotropic distillation column in a quantity such that the sump product contains 0À5 to 6% of water and acetic acid is obtained as the sump product. In a continuous process the tail acetic acid may be recycled through an evaporator to a reaction vessel in which vinyl acetate is prepared by reacting ethylene, acetic acid, molecular oxygen in the gaseous phase over a noble metal catalyst. A reflux ratio, based on the vinyl acetate of 3 to 8 is preferred. A second azeotropic distillation stage may be used to remove final water and acetaldehyde, and polymer impurities, and acetic acid traces are removed by a final distillation. In a modification an intermediate side stream may be withdrawn from the azeotropic distillation column and combined with the sump product to pass to an evaporator before recycling to the vinyl acetate production stage. This ethyl acetate rich liquid side stream may be taken from the distillation column, e.g. between the 8th and 16th plate of a 60 plate column.

Title: Improvements in systems of electrical distribution
IPC: H02M7/00
Filed: 1925-09-23
Abstract: 240,461. British Thomson-Houston Co., Ltd., (Assignees of Prince, D. C.). Sept. 23, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Systems depending on static transformers; regulation, automatic. - An interphase transformer, connected between direct and alternating current circuits one of which is loaded and the other supplied with current, is so proportioned and constructed that a change in the degree of saturation of its core resulting from load changes causes a corresponding opposing change in the load current which maintains the load circuit voltage constant. This action may be modified by a third winding on the transformer arranged to maintain a predetermined saturation of the core. Fig. 1 shows a system for converting threephase current in mains 1, 2, 3 into direct current at load terminals 9, 12. The transformer 4 has two sets of star-connected secondaries 5, 6 connected at their neutral points to the terminal 9 through the windings 7, 8 of one interphase transformer with a central core 13 and air gap 14. The secondaries are also connected through rectifiers of any type to the terminal 12, the Figure showing thermionic valves with filaments supplied from a transfoirmer to the midpoint of the secondary of which the terminal 12 is connected. Increase of load on the system causing an increasing saturation of the unidirectional flux in the core 13 of the interphase transformer results in the practical elimination of this transformer and a gradual rise in output voltage in the proportion 0.995 to 0.827. The core 13 may carry a winding giving an opposing flux. An auxiliary source 16 is connected to this coil 15 and a relay 18 responsive to the voltage 9, 12 is arranged to short circuit a resistance 17 to bring this coil into action when a rise occurs in the output voltage. A system for converting direct to alternating current is also described using three electrode valves with the grids supplied for transformer windings inductively related to the main windings and connected by a second interpbase transformer arranged as in Fig. 1 so that simultaneous changes take place in the supply to the grids. The system is applicable to single and quarter phase rectifying arrangements with differing ranges of regulation.

Abstract: 155,395. Baker & Sons, J., Prescott, W. E., and Pointon, J. E. Sept. 27, 1919. Filling cans and like receptacles.-Mechanism for feeding and conveying open receptacles, e.g. tins, to a machine for filling them with paste, liquid or powder, comprises a hopper a containing a conveyer b provided with elements b<4> adapted to enter the open sides or mouths of the receptacles x and convey them open side downwards about a revolting member c to a position in which they leave the conveyer and pass to an inclined shaking plate or table f with their open sides or mouths directed upwards. The hopper is provided with an adjustable brush d which engages the receptacles and brings them into proper position for movement by the conveyer elements, or returns incorrectly-placed receptacles to the hopper. An adjustable guard e is provided for the purpose of retaining the receptacles on the conveyer for the desired distance. The shaking movements are imparted to the table through a lever f<1> by means of a cam or eccentric f<2> driven from the main driving-shaft f<4>, which also drives the conveyer b through a belt c<1>, bevel-gearing c<3>, shaft c<4> and worm c<5>. The receptacles are brought more or less into alignment on the table by a rotary brush f<5> and are finally definitely spaced either in rows or singly by a rising and falling gate g which is mounted on pivoted arms g<1> and operated by a lever g<2> engaging a rotary cam or ratchet-wheel g<3>. The table is also given a reciprocating movement by connecting it to a slide g<5> operated by a lever g<6> connected by a rod g<7> to a crank-pin on the wheel g<3>. The receptacles are thus fed from the table f to a convever h at desired distances apart and are carried beneath a filling-machine. The latter comprises a hopper i containing rollers i<1> which feed the material to one or more delivery dies i<2> which are opened or closed at the desired moments by means of slides i<3> actuated by rods i<4> and levers i<5> coupled by a rod i<6> for synchronous movement. The dies are mounted on a slide j to which reciprocating movement is imparted from a crank disc j<1> through a rod j<2>, in order that the dies may move with the receptacles during the filling operation and then return to their original position ready to fill another batch of receptacles. Alter the filling operation, the receptacles may be transferred from the conveyer h to another conveyer k by means of a gate m operated by a slide reciprocated by a lever m<3> having an arm m<4> engaging a cam m<5>. Rising and falling movements are imparted to the slide and gate by means of a rod n and lever n<1>. The levers m<3>, g<6> may be coupled together by a rod m<7> in order that the two gates may be moved in proper timed relation. A reciprocating knife-edge o may be provided to assist in stripping the receptacles from the slats of the conveyer h. The conveyer k carries the receptacles through a cooling-chamber P through which air, cooled by brine pans l<20>, is circulated by a fan l<3>.
