Patent GB-383384-A (GB)
Title: Process for the cracking of heavy oils and apparatus therefor
IPC: F23D11/44
Filed: 1931-10-24
Abstract: <PICT:0383384/III/1> Heavy oils are cracked to produce a gaseous mixture suitable for ignition in a gas engine or for lighting purposes by passing the oil vapours mixed with superheated steam over coke in a high frequency field.  Oil vapours are led through a pipe L on to coke packed in a chamber I formed between a vessel A packed with insulating material K and a porous cylinder H, while superheated steam is led through a pipe N into a chamber II formed between the cylinder H and a porous bottle J.  A high frequency field is formed by passing a current of 220 volts through a transformer U, the induced current being led through a condenser M, a quenched or rotary spark gap S and a coil G surrounding the chamber I.  A direct current field is superposed on the high frequency field by connecting the bottle J to the positive terminal and the cylinder H to the negative terminal of a suitable source of current having a voltage of 500-1000 volts and the steam is thereby ionized, the oxygen passing off through the cylinder J, while the hydrogen passes through the porous walls H to mix with the oil vapours. The vapours produced pass off through a pipe O and are mixed with oxygen from the bottle J and also with oxygenated air formed by drawing in air over the serrated edges of the condenser M. Alternatively the vapours and the oxygen may be collected separately.  The walls of the cylinder H, the coil R and the spark gap S may be formed of or coated with metals by fritting the finely divided metals in known manner in a high frequency field.

Abstract: 144,959. Beadle, E., and Harwood, A. R. Nov. 27, 1919. Wick burners, blue flame; wick-operating devices.-In a flat wick burner of the type in which a portion of the vapours generated on the exposed surfaces of the wick enters into direct combustion whilst the remainder is mixed with air before combustion, the top baffle-plate of the burner is formed with a longitudinal hollow rib on its underside. The burner shown in Fig. 4 comprises a base-plate a adapted to be secured by a screw in a seating in the lamp or stove reservoir, a wick-tube b held in position in a slot in the base-plate by the hooked ends of a bracket or plate c, a slotted top plate f formed with the depending hollow rib f<2> and detachably supported over the wick-tube by end plates g, and an airbox or baffle chamber h and an angle-plate i fixed to the plates g and fitting against opposite sides of the wick-tube. The air-box h is perforated at the bottom and allows the passage of air to the flame on that side of the wick. The vapour from the other side mixes with air heated by its passage past the rib f<2> and burns above the wick. The wick-tube is preferably higher on the non- burning side of the wick. The wick-adjusting spindle d may have integral roller portions d', and is arranged in a casing e. The top plate f may be provided with a strengthening rib on the opposite side to the rib f<2>. Fig. 6 shows a double wick burner having two air-bores h adjacent to the outer sides of the wick tubes, the top plate being formed with two parallel slots having a single deflector rib f<2> between them.

Title: Improvements in tea-leaf cutting apparatus applicable also to the operations of rolling and roll-breaking
IPC: A23F3/12
Filed: 1932-10-24
Abstract: 390,757. Cutting tea &c. BROWN & CO., Ltd., Chatham Street, Colombo, Ceylon.- (Assignees of Bryan, F. ; 200, West Parade, Lincoln.) Oct. 24, 1932, No. 29758. Convention date, Nov. 3, 1931. [Class 129.] A tea-cutting machine, which may be adapted for roll-breaking, comprises an eccentrically-arranged rotary knife, and a pressurefeed mechanism, the two being driven in opposite directions by bevel gearing. The knifeblade h is attached to a sleeve i which is rotated by gearing l through a driving shaft z supporting fast and loose pulleys m<1>. The same shaft drives a vertical spindle d, through gearing k, and a screw s which forces down tea from a hopper b through an annular space m traversed by the knife h. A bearing plate n, which may be spring-loaded, supports the tea for cutting. Cut leaves are ejected radially into a hopper p which guides them to a sieve q through which finely cut leaves are deposited into a trough r<1>. Larger cuttings pass over the sieve into a trough q<1> where they are collected and replaced in the hopper b. The cone r supporting the sieve q is supported on springs, and given a vibratory motion through the action of rollers t<1> and a rotary cam-track t. A loose flanged piece g prevents the escape of leaf when the screw s and extruding device c are forced upwards against a supporting spring e by the pressure of the feed under the screw vanes. The length of the cut may be varied by adjusting the position of the plate n in relation to the knife, by means of levers o pressing upon a ring-member o<2> which in turn controls the position of the plate n through the medium of bolts o<3>. Other means, such as a cam, may be used to adjust the plate n. The length of cut may be varied by changing the gearing to alter the relative speed between the feeding gear and the knife blade. The cutter may have several cutting edges, may be other than circular, and may be supported at different heights. For sharpening purposes the knife blade can be secured to a clamp x on the driving-shaft and rotated in contact with abrasive means. A scraper plate may be attached below the knife and revolve with it. For roll breaking purposes, the knife-blade is removed and replaced by a plain or corrugated disc which co-operates with a flanged part of a removable fitting which is substituted for the lower part v<1> of the feed hopper. A second disc may be used which is attached to the spindle d. Various parts of the machine are made of stainless steel or other non-corrodible material. Metallic foreign matter is removed from the tea entering the hopper b by electromagnetic means. The number of sifters may be varied.

Abstract: 1,224,383. Automatic control of light intensity. DR. -ING. RUDOLF HELL. June 25, 1968 [July 27, 1967], No.30311/68. Heading G3R. A recording lamp controlled in dependence on an input signal in electronic line-by-line photographic reproduction apparatus is also controlled by a negative feedback signal from a photo-cell responsive to light from the lamp. As shown, a a discharge lamp 4, used for photographic recording in picture telegraphy apparatus, is supplied in series with a triode valve 1 which is grid modulated to produce the picture. Light from the lamp passes through a diaphragm 7 and lens 5 and 8 to recording paper or film 9 on a rotating drum 10. A portion of the light is reflected by a semitransparent mirror 12 on to a photo-cell or photomultiplier 14 the amplified output of which is fed back negatively to the grid of valve 1. Light intensity is thus maintained in correspondence with the magnitude of the modulating signal even if the lamp is changed. A linear relationship between the light intensity and the modulating signal is achieved by suitable choice of the characteristics of photo device 14. Several discharge lamps may be operated simultaneously.
