Title: Improvements in or relating to honey extractors
IPC: A01K59/04
Filed: 1934-10-03
Abstract: 440,511. Centrifugal honey-extractors. BURTT, E. G., 22, Stroud Road, Gloucester. Oct. 3, 1934, No. 28361. [Class 23] The cage or carrier 14 for the combs in a honey-extractor is rotated by means of a handle 10 through skew gearing in the casing 5 mounted on the cross beam 7 at the top of the barrel 8. The toothed pinion 1 on the spindle 2 gears with the worm 3 which can slide and rotate on its spindle 4<a>. A slot in the lower end of this spindle rests over a cross pin at the upper end of the spindle 4 of the carrier 14. The beam 7 has slots 11 near its ends to pass over studs on the brackets 12 so that the beam can be secured by wing nuts. When the handle is turned in one direction, the worm 3 is rotated and depressed so that ratchet teeth on its lower end engage similar teeth on a collar 17 fixed to the spindle 4a thereby coupling the carrier 14 to the gear. When the handle is released, the worm moves upwards to disengage the coupling, and the carrier rotates with a freewheel action. If the handle is rotated in the opposite direction, the worm is lifted and its upper end engages a collar 18 on the spindle, thus forming a friction brake. A spring may be employed to assist the worm to move to its normal position.

Patent GB-683344-A (GB)
Title: Process of making substituted 4-methyl coumarins
IPC: C07D311/16
Filed: 1950-11-24
Abstract: 4-Methylcoumarins, containing a substituent in the benzene nucleus or having a further ring fused thereto, are manufactured by the action of a dehydrating condensing agent on an acetoacetic ester of the general formula <FORM:0683344/IV (b)/1> (wherein R represents one or more substituents or a fused-on ring) obtainable by reacting the corresponding phenol with an equimolecular proportion of diketene in the presence of an esterification catalyst at an elevated temperature not substantially above the melting point of the phenol.  Suitable starting materials (which need not be isolated in the pure state) are the acetoacetates of the phenol homologues (e.g. cresols and xylenols) and the naphthols, and the mono-acetoacetates of polyhydric phenols.  The condensation is advantageously effected by running the acetoacetate into the condensing agent at a temperature between 0 DEG and about 50 DEG  C.  In examples: (1) resorcinol is fused with a small amount of pyridine and an equimolecular proportion of diketene is run in, and the resulting monoacetoacetate is run into 78 per cent sulphuric acid, producing methyl umbelliferone; (2) pyrogallol similarly yields 7 : 8-dihydroxy-4-methylcoumarin; (3) 6-hydroxy-4-methylcoumarin is similarly prepared from hydroquinone, except that the first step is carried out in benzene solution; (4) a -naphthol is treated as in (1) to produce 4-methyl-1 : 2-a -naphthopyrone; (5) diketene is run in a slow jet into a heated mixture of p-cresol with a trace of dimethylaniline, and the resulting acetoacetate is treated as in (2) to form 4 : 6-dimethylcoumarin; (6) resorcinol is reacted with diketene in the presence of triethylamine and the product is run into concentrated phosphoric acid, producing methylumbelliferone.  Zinc chloride is additionally specified as a condensing agent, and sodium acetate, benzenesulphonic acid and concentrated sulphuric acid as esterification catalysts.

Title: Improvements in heat-exchanging elements
IPC: F28C3/00
Filed: 1934-10-10
Abstract: 445,045. Drying apparatus. SHORT, A. A., 2, Aylesbury Road, Thame, Oxfordshire, and DUNLEAVIE, C. E., 2, Bunkers Hill, Oxford. Oct. 10, 1934, No. 29053. [Class 34 (ii)] [See also Group XII] Heat-exchanging elements for use in kilns, coolers, driers or other apparatus for promoting heat exchange between different, materials, such as a semi-liquid and a gas, comprise members of tubular form each having a protuberant portion or portions so shaped and disposed with respect to adjacent parts of the element that when the elements are jumbled in use the protuberant portions will constitute scrapers and exert a scraping and cleaning action on other elements in the apparatus. The elements are intended more particularly for use in the drying of cement slurry and serve to keep the slurry permeable to the hot drying gases. Many different forms of element are shown and described. Fig. 1 shows an element of approximately double bell shape with a protuberant flange 10 at each end and with side apertures 31. In addition each flange may have one or three protuberant lugs, the lugs at the two ends being relatively staggered. The element shown in Fig. 3 comprises two bottomless dish-shaped end parts 11 joined by two outwardly concave bridge parts 13, the outer margins 12 of the parts 11 forming the protuberant scraping portions. In other modifications the element is in the form of a perforated or unperforated cylindrical tube 18 with an undulatory flange at each end forming projecting teeth 20, Fig. 13, or of a tubular member flared at each end and of circular or approximately polygonal section with concave sides 28, Fig. 20. Fig. 14 shows an element which at one end 21 is of circular section and at the other end 22 is of elliptical section. Fig. 21 shows a cylindrical member cut away at its ends to form protuberant teeth 17 and which may also have a row of radially disposed lugs 27. If the lugs 27 are omitted the ends of the member may be outwardly flared.

Title: Improvements in and relating to television and the like transmission systems
IPC: H01J29/02
Filed: 1935-10-22
Abstract: 464,692. Television transmitters. SHOENBERG, I. Oct. 22, 1935, No. 29151. [Classes 39 (i) and 40 (iii)] In a television transmitter, such as the iconoscope, in which the object 1, Fig. 2, and its image 5 are disposed off the axis XY of the lens L, it is found that the illumination of the image 5 decreases from the edge nearer the axis XY to the opposite edge. According to one aspect of the invention, this is compensated by a suitably graded filter 9 before the object 1. According to another aspect of the invention, the compensation is effected by increasing the size of the scanning spot, in accordance with the decrease in intensity across the image, while maintaining its intensity per unit area constant. Saw-tooth oscillations, applied to valve 22, Fig. 3, are amplified by valve 23 and flow through the deflecting coil 21. The valve 22 is also coupled to valve 27, whose output is applied from a potentiometer 28 to a focusing electrode 15 to vary the size of the scanning spot. The output of valve 27 is also applied from potentiometer 29 to a control electrode 14 to vary the spot intensity, so as to maintain its intensity/unit area constant. Where a scanning light beam is used, the cathode ray beam of Fig. 3 may impinge on a fluorescent screen to produce a luminous spot. According to another aspect of the invention, compensation may be effected by controlling the amplification of the picture signal amplifier, as by applying the deflecting oscillations to the screen grid of a variable-mu valve. Specification 444,074 is referred to.
