Abstract: 279,376. Krupp Akt.-Ges., F. Oct. 25, 1926, [Convention date]. Alloys.-Sintered hard metal alloys consisting mainly, of a compound such as a carbide, nitride, or silicide of a refractory metal such as tungsten with one or more metals such as iron, nickel, or cobalt, are made from such finely ground materials that no pores are recognizable in the product at a magnification of at least 50 times. Tungsten may be ground in a ball mill to less than 1 Î 10<-4> mm, and converted into carbide by heating in an oxidizing atmosphere in a gas-heated furnace with a slight excess of carbon, the resulting carbide being ground to the above size and mixed with 5 per cent of cobalt which has been similarly ground. The mixture is then subjected to further grinding for at least 50 hours, and a pressed body is formed from the product, sintered at 700-1100‹ C., worked, and further sintered at 1300-1600‹ C.

Title: Improvements in cigar making machines
IPC: A24C1/04
Filed: 1932-03-15
Abstract: 383,846. Cigar making machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(International Cigar Machinery Co. ; 5520, 2nd Avenue, Brooklyn, New York, U.S.A.) March 15, 1932, No. 7719. [Class 130.] In order to increase the speed of laying and cutting cigar wrappers, two or more cutting beds or dies are brought successively into position for laying the leaf sections thereon and then into position for delivery of the wrappers to the wrapper-carrying device, the dies engaging stationary pressure rollers which effect the cutting operation as each die passes from one position to the other. Figs. 1 and 2 show a horizontal turret 13 carrying a pair of opposed dies 33 and arranged to be rotated intermittently through half-revolutions so as to bring each die from the position shown at the bottom of Fig. 1, which is the laying position, into the upper position, from which the cut wrapper is delivered to the wrappercarrying device for conveyance to the wrapping- mechanism, the die passing under pressure rollers 15 which effect the cutting. The leaf sections are held upon the dies by suction transmitted from a pipe 22 through a valve 25, which is oscillated to and fro about the turret shaft 12 by gearing 35, 36 and cam 41. During one movement of the valve 25, the turret is locked thereto by a bolt 44, but during the return movement of the valve the bolt 44 is released, and the turret is held stationary by another bolt 59. These two bolts are simultaneously moved in opposite directions by arms 51, 52, 54 and a cam 56. The valve 25 is constructed so that suction is communicated to holes 97, 99 to retain the whole leaf during the half-rotation of the turret from the laying to the transferring position. When in the latter position, the suction is cut off from the inner holes 97, so as to release the cutter wrapper for transference, whereas the suction on the outer holes 99 remains so as to retain the surplus leaf portion, until the die returns again almost to the laying position, when the outer suction is cut off to allow removal of the surplus previous to the laying of a fresh leaf. The wrapper-carrying device 17 for transferring the cut wrapper to the device 19 for winding it on the bunch C is carried by, and supplied with suction through, a head 80, arms 79, 77, and a pedestal 16, about which the arm 77 is oscillated by gearing 70, 71, arm 74, and cam 76. Movement of the carrier 17 during its oscillation is effected by arms 81, 84, 86 engaging at 82 and 85 in slots in a stationary cam plate 18. Die blocks arranged within the dies 33 are raised a small distance above the knife edge in the laying position, so as to protect the operator's hands, these blocks being lowered below the knives as the die passes under the rollers 15.

A process, for preparing compounds of Formula I comprises reacting a 6-amino penicillanic acid of the Formula II: wherein R is as hereinbefore defined with an α- phosphonoacetic acid of Formula III: or an acylating derivative thereof. Pharmaceutical and disinfectant compositions having antibiotic properties may be prepared from compounds of Formula I in conjunction with suitable carriers. α-Phosphonophenylacetic acid- P,P-diethyl ester is prepared by reaction of benzylphosphonic acid diethyl ester (obtained by refluxing a solution of triethyl phosphite acid benzyl chloride) with carbon dioxide in the presence of butyl lithium. Hydrolysis yields the corresponding P-monoethyl ester and the free α-phosphonophenyl acetic acid. α-Phosphonophenyl acetic acid-P,P-dibenzyl ester and the corresponding P-monobenzyl ester may be similarly prepared. α-Phosphonophenylacetic acid may also be prepared by heating chlorophenylacetic acid ethyl ester with triethyl phosphite to yield α-phosphonophenylacetic acid triethyl ester and hydrolysing this to convert it to the free acid.

Abstract: 671,920. Tubular heat-exchangers; steam boilers and superheaters. HUET, A. March 17, 1948 [March 17, 1947; April 25, 1947], Nos. 7966/48 and 7967/48'. Classes 64(iii), 123(ii) and 123(iii) A tubular heat-exchanger, e.g. a watertube boiler, steam superheater, economizer, or air heater, comprises a group of tubes and means, e.g. a baffle or baffles, which divide a subsidiary stream of hot gases from the main stream of those gases flowing over the tubes, the subsidiary stream forming a zone of hot gases of lower speed and higher static pressure than the main stream, so that a gaseous baffle is formed between the tubes to cause the main stream to follow a predetermined path. In a water-tube steam generator, Figs. 1 and 3, with steam super-heater tubes 11 between the water-tubes 4, 5, pairs of strip-shaped baffles 16 with a narrow gap between them are arranged between groups of superheater tubes, to divert the hot gases laterally into those groups. Auxiliary baffle strips 17 are located behind the baffles 16, and baffles 15 are located between the boiler wall and the superheater tubes. Unsymmetrically corrugated plates may be arranged between rows of tubes in each group. Baffles 18 are provided to divert hot gases into the superheater assembly. In an economizer, Fig. 5, hot gases from an inlet 24 are caused to flow back and forth across the tubes 22 to the outlet 25 by baffle plates 28, 29 and curved walls 26, 27. The plates 28, 29 are so shaped and related to the adjacent parts of the wall that zones X, Y of relatively stationary gas are formed. A branch conduit 30 conveys hot gases direct from the inlet 24 to a point adjacent to the plate 29. In a modification, the plate 29 is replaced by a pair of convergent plates forming a a nozzle to which the branch conduit 30 delivers hot gases. Another branch conduit may deliver hot gases to the lower parts of the tubes 22. A soot blower pipe 31 may be provided. Specifications 471,342, [Group XXXIII] and 628,416 are referred to.

Abstract: 1344434 Coating compositions BERGSTROM PAPER CO 21 Feb 1972 [24 Nov 1971] 7990/72 Heading C3P A non-aqueous composition for use in coating substrates has a dough-like consistency and comprises a finely divided pigment having an average particle size of 0À2 to 5 microns, a solution of synthetic resin binder in an organic solvent, and ingredient means (as defined below) for completely wetting the pigment, the resin binder constituting 5-30 wt. per cent (based on the pigment) of the composition, and the amount of solvent being only that necessary for a doughy consistency. The ingredient means is a generic term for a rheological modifier, a dispersing agent for the pigment and an antiflocculating agent to prevent flocculation of the pigment particles. Such means need not necessarily comprise three separate compounds for each of the components, since two or even one compound may serve all three purposes. The binder is preferably a thermoplastic polymer, polyvinylacetate being exemplified. Pigments specified are ZnO, kaolin clay, bentonite, fuller's earth, CaCO 3 , TiO 2 , silicas, and BaSO 4 . Organic pigments may also be used, and a mixture of pigments may also be used. Ingredient means specified, which are in fact rheological modifiers which serve all three purposes mentioned, are cationic, anionic, or nonionic surfactants of the conventional type, lubricants, e.g. metal carboxylates such as stearates, or antifoaming agents such as polyalkyl siloxanes. In the examples the ingredient means comprises, (1) and (3) an animated complex fatty acid ester and zinc naphthenate, and (2) a cocoaamine surfactant and zinc naphthenate. In the examples, the polymer and pigment are milled together and the diluent and ingredient means then mixed in. On dilution with further solvent, coating compositions are formed which can be coated on to many types of paper, polymer films, board, fibres, &c.
