Title: Improvements in or relating to high tension electrical switch gear
IPC: H02B1/00
Filed: 1923-01-19
Abstract: 212,039. Davies, D. R., and Metropolitan-Vickers Electrical Co., Ltd. Jan. 19, 1923. Oil-switches; earthing; switchboards.-In hightension heavy-current switchgear of the type in which duplicate sets of bus-bars are used, instead of employing a main oil-break circuit-breaker interlocked with alternatively-operable selector switches for each set of bus-bars, the selector switches not being capable of breaking the circuit as they are only opened after the circuit has been broken by the main switch, the main oil circuit-breaker is omitted and selector switches for each set of bus-bars are employed which are capable of breaking heavy currents under abnormal conditions. As shown in Fig. 1, the incoming feeder 3 is divided into two branches 6. 7 connected by alternatively-operable circuit breakers 4, 5 to duplicate sets of bus-bars 1. 2. In the constructioual form shown in Fig. 2. cir cuit-breakers 9. 10 forming the selector switches are arranged back to back, their adjacent terminals 11, 12 being connected through a T-connection 14 to the feeder 15. Two sets of bus-bars 1, 2 are located in their casings 17, 18 adjacent to the tops of the circuit-breakers 9, 10 and to their operating mechanisms 23, 24. The earthing switch comprises a contact 26 operated by a screwed rod 27 which passes through a fixed nut 29, the contact 26 co-operating with a fixed contact mounted on the cable T-piece 14. Interlocks of known form are provided between the operating mechanisms of the circuit-breaker oil-tank lowering gear so that earthing may be effected after the circuit-breakers 4, 5 are opened, their contacts being effectively earthed before the tanks are lowered. In the modification shown in Fig. 3 the feeder 15 is brought from the trifurcating box to an oil filled chamber 33 containing isolating switches 34, 35, the remote contacts of which are connected through leads 36, 37 to the terminals 11, 12 of the circuit breakers 9, 10 which act as selector switches. The switches 34, 35 are interlocked with the alternatively-operable circuit-breakers 9, 10 so that they may be opened only after the circuit has been broken.

Title: Improvements relating to the fractional distillation of crude oil and other liquids
IPC: C10G7/00
Filed: 1921-01-11
Abstract: 182,827. Mather, P. Jan. 11, 1921. Distilling hydrocarbons; column stills and rectifiers; film evaporators.-In the fractional distillation of crude oil or other liquid in which the oil is preheated and partly evaporated by the stillresidues and the hot vapour fractions a series of heat-exchanger units is so arranged that alternate units are traversed in succession by the still residue in counter current to the oil and each. of the remaining alternate units is traversed by a vapour fraction of a temperature higher than that of the fraction in the preceding unit. In the preferred fcrm of apparatus shown, the still is of the kind described in Specification 175,666, the heat-exchangers g, g<1>, g<2>, g<3> are of the kind described in Specification 182,828, and are arranged vertically one above the other, and the water-cooled condenser h is divided into separate compartments, one for each fraction of the still vapours and one for the vapours from the crude oil in each heat exchanger. The crude oil is forced up a pipe j<1> by a pump and sprays or drips through perforated pipes j<2> to film over the tubes of the nests i<4>, b<2> in the exchanger g. It is similarly sprayed or dripped by gravity in each of the progressively hotter exchangers g<1>, g<2>, g<3> so as to film successively over the nests i<3>, c<2>, i<2>, d<2>, e<1>, e<2>. The vapours evolved in the exchangers pass respectively through the pipes g<6>, g<7>, g<8>, g<9>, to the respective compartments of the condenser h. The heated oil discharged through the pipe g<4> is raised by a pump g<5> to the top of the still a through which it gravitates in an interrupted current as described in Specification 175,666. The vapour fractions from the progressively hotter compartments b, c, d, e pass by the pipes b<1>, c\ d<1>, e<1> to the hot vapour units b<2>, c<2>, d<2> e<2> in the heat exchangers, any gas or vapours not condensed in the exchangers passing on by pipes b<3>, c<3>, d<3>, e<3> to the respective compartments of the condenser h. The still-residue is drawn from the compartment f by a pump i and forced in succession through pipe i<6>, tube-nests i<1>, i<2>, i<3>, i<4> in the heat-exchangers, and discharge pipe i<5>. The main and branch supply pipes for the hot stillresidue may be provided so that the amount of residue passing through any exchanger may be controlled. The exchangers may be lagged or water-cooled, and, as described in Specification 182,828, thin metal curtains with serrated edges may be provided to assist or direct dripping of the oil, metal wall-sheets and roofs may be inserted to prevent splashing of crude oil on to the casing, and a gutter may be provided between the casing and the wall-sheets to collect liquid condensed in the exchangers. Steam may be injected to the exchangers to assist vaporization of the crude oil. The vapours from the still and from the exchangers may be passed through dephlegmators before passing into the tube nests or into the condenser h.

Title: Improved means for shaping hollow metal parts
IPC: B21D26/02
Filed: 1919-01-24
Abstract: 138,681. Todd, A. B., Beddie, J. S., and Beddie, J. A. Jan. 24, 1919. Stamping.-Hollow tubular blanks for metal articles, such as brass coupling tail-pieces for pipes, while being shaped by applying internal or external fluid pressure to cause the blank to take the shape of a die or mandrel, and simultaneously compressing or extending the blank by mechanical means, are held in a two-part die, one part b of which has a recess for the one end of the tube, and the other part is shaped to the desired form of the article. In the example shown, a plunger g working in the cylinder i forces fluid up the hollow plunger and ejector e into the blank c, ejecting air through the upper die b and vent p in the ram a, until this vent is closed by the upward movement of the die b caused by pressure on the plunger e. This pressure, and the internal fluid pressure, force the blank into the recesses of the die d, and holes f allow for the escape of any fluid between the die and the blank. A pressure gauge m and safety-valve n may be provided.

Title: Means for regulating the strength of sound in photo-electric reproduction from soundfilms
IPC: G11B7/00
Filed: 1928-01-24
Abstract: 284,285. Kiichenmeister, H. J. Jan. 27, 1927, [Convention date]. Optical apparatus.-The volume of the sound reproduced from an optical record by transmitting light through the record on to a photoelectric cell is controlled by varying the intensity of the light. This may be done directly, as shown in Fig. 1, by controlling through a rheostat 7 (which may be arranged in the auditorium) the current passing through a lamp 5 serving as the source which illuminates the film record 1 ; or an adjustable screen 4, such as an iris diaphragm, or a rotatable disc formed with apertures of different sizes, may be interposed between the lamp and the film. Fig. 3 shows an arrangement wherein a prism 11, the angular position of which may be adjusted and indicated by a pointer, is placed between the lamp 5 and the record 1, so that the amount of light falling on the record may be varied by deflection. Mirrors &c. may also be used for deflecting the light to any required extent from the path along which it is directed by a condensing lens. A further alternative, shown in Fig. 4, consists in mounting a number of lamps, of differing luminosities, on a rotatable carrier 14, so that any desired lamp may ba brought into the operative position. When using a constant source of light, the effective light falling on the iecord may be varied by interposing between the source and the record any one of a number of colour filters (which may be mounted in a common holder), or by using an adjustable screen (for example a grey disc) of graded transparency. Magnetic apparatus.-The Specification as open to inspection under Sect. 91 (3) (a) also refers to the regulation of the strength of sound reproduced by electromagnetic means, by varying the distance of the magnet from the "magnetogram." This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 214,274 and 225,840.

SOCIETA IN ACCOMANDITA SEMPLICE DI ENZO SERAGNOLI E ARIOSTO SERAGNOLI]. 19 Jan., 1966 [26 Jan., 1965], No. 2554/66. Headings B8A and B8C. Cigarettes are supplied from a hopper 21 to separate stations C, D, E, Fig. 2, where they are fed into pockets 47 of an intermittently moved conveyer B, to form successive layers of 7, 6 and 7 cigarettes respectively, by means of a pusher 48. Each group of 20 cigarettes thus formed is ejected from the conveyer B by a pusher 51 and passes to a packaging machine. The number of layers of cigarettes in each group invariably equals the number of stations. The cigarettes may be formed into groups of a different number, and there may be either two or more than three stations at which the conveyer pockets are filled. Each head 50 of the pusher 48 may be separately driven. Before passing into separate groups of channels 26 in the hopper 21, the cigarettes are vibrated by means of oscillated shafts 30 of polygonal crosssection. Cigarettes pass from the lower ends of the hopper stations which are placed at different heights, between side guides 53 and across supporting blades 36 into the conveyer pockets. A spring (35), Fig. 3 (not shown), keeps the cigarettes in position as they leave the hopper, and an element 45 overlies them when in the conveyer pockets. In a modification, Fig. 5 (not shown), the cigarettes are fed into pockets on a rotary drum. The form of the conveyer pockets may be varied, Figs. 6-8 (not shown), e.g. to provide for an ejecting element carried on a continuous chain, in place of the pusher 51.

Title: Improvements in and relating to clutches
IPC: F16D43/26
Filed: 1940-02-10
Abstract: 538,657. Clutches. LOEWY ENGINEERING CO., Ltd., and HENSCHKER, E. Feb. 10, 1940, No. 2605 [Class 80 (ii)] In clutch-operating gear the elements which move the shifting lever into the engaged position are returned to the disengaged position before a driven shaft has completed one revolution, the shifting, lever itself being locked in the engaged position until the shaft has made one revolution whereupon the locking means are released and the shifting lever is returned to the disengaged position. A clutch member 11 splined to a driven shaft 12 is moved into and out of engagement with a clutch member 10 by a shifting lever 15 pivoted on a fixed shaft 16. An operating lever 17, also pivoted on 16, and the lever 15 are pressed together by a spring 23, and a spring 22 tends to pivot the lever 17 in a direction to engage the clutch. A trigger 20 holds the lever 17 in the disengaged position. When the trigger 20 is tripped the clutch is engaged, movement of the lever 15 also causing lugs 27 connected thereto to engage fixed catch plates 28. Before the shaft 12 has made one revolution a cam 19 on the shaft 12 engages a roller 18 on the lever 17 and moves the latter to the disengaged position where it is held by the trigger 20. The lever 15 cannot disengage owing to the locking action between the parts 27, 28, and the spring 23 is therefor stressed. When the shaft 12 has completed one revolution a roller 30 on the member 11 engages a cam 29 connected to the lugs 27 and the latter are disconnected from the plates 28. The lever 15 thereupon snaps back into the disengaged position and into contact with the lever 17.
