IPC: A01B13/00
Filed: 1921-03-11
Abstract: 181,471. Willans, K. W. March 11, 1921. Single-tool implements; rollers, hand.-An implement for digging or cleaning out ditches &c. comprises a vertical frame A provided on each side with a downwardly and forwardly extending blade B, these blades being bent laterally like a ploughshare to deposit the excavated soil at each side of the implement. Horizontal plates A<1> A<2>, spaced apart, are secured to the vertical frame, and filling-in blocks of wood are arranged behind the blades B. A knife-edge a is secured to the vertical frame to cut roots encountered during the operation of the implement. The plate A' carries by means of a bracket C<2> and a pivot C<1>, a sledge C, which may be adjusted vertically and which is arranged in front of the blades B to control the depth of the ditch cut. A wheel may be used instead of the sledge, and more than one sledge or wheel may be employed to enable the implement to follow a curved path. A detachable tine B' may be arranged in front of the blades B to break up very hard soil. Root cutters or steel prongs may be fitted behind the implement so that they project into the soil below the blades. A rearwardly projecting lever may be provided on which the attendant can press to hold the tools in the ground, or, as shown, a lever E may project on one side by which the attendant can control the implement. A vertically adjustable wheel may be arranged at the end of this lever. The soil that is raised is pressed sideways and compared by vertically-adjustable inclined plates G or rollers H. One or both of the plates G may be spring controlled. The blades B and the sledge C may be duplicated at the rear of the implement so that it may operate when travelling in the reverse direction. In a modification the rear of the frame carries a rearwardly and downwardly extending plate which, on the machine travelling in the reverse direction, cleans out the ditch just cut. This plate may be formed by two longitudinal members adjustable to suit the size of the ditch. The implement is drawn by ropes F attached to a steam winch or similar machine; the ropes F are secured to adjustable brackets F<x>. In a modified form of machine only one blade B is used.

Title: Process for producing citric acid
IPC: B22D19/00
Filed: 1936-03-17
Abstract: In the production of citric acid by fermenting a suitable carbohydrate with a mould such as Aspergillus, Sterigmatocystis, Penicillium, Citromycetes or Mucor in an acid medium such as pH=3.4, for example, at 26--35 DEG  C., the residual carbohydrate and part of the colloids are removed by adding to the filtered solution a soluble calcium compound and fermenting with yeast. After a second filtration the liquor may be treated with decolorizing carbon and oxalic acid is then added to remove the calcium.  The citric acid is recovered by concentrating and cooling the solution.  The calcium compound added to facilitate the yeast fermentation may be basic or neutral such as the hydroxide, phosphate or acetate or calcium ammonium phosphate, the quantity being 0,1--1 per cent.

Title: Improvements in or relating to fabric take-up mechanism for straight-bar knitting machines
IPC: D04B11/32
Filed: 1940-10-11
Abstract: 598,705. Knitting-machines. MILLER, M. C. Oct. 11, 1940, No. 8307/47. Convention date, Nov. 12, 1938. Divided out of 598,647. [Class 74 (ii)] Welt wires inserted in the welt portion of a fabric knitted on a straight-bar machine are engaged by hooks provided on straps of a takeup mechanism to withdraw the completed fabric from the needles. The take-up mechanism is described in connection with the machine disclosed in Specification 598,647 and comprises straps 270, provided at each end of each section of the machine and carrying hooks 292, engaging with welt wires, and supported on pulleys, one, 282, of which is mounted on a driving shaft 284. The driving shaft pulley 282 takes up the straps to an extent sufficient to maintain a tension of the fabric until the fabric is pressed-off at which point the welt wires drop from the hooks together with the fabric into a hopper 307. The driving shaft is driven by a counterweight connected to a cord wound round a drum on the shaft. On completion of the fabric, the counterweight is reset by means of a second counterweight, attached to a cord coiled on a drum, which is brought into operation through the medium of a clutch. The effect of the reset counterweight is to rewind the second and reverse the motion of the straps until they are in position to receive the next welt wire. The straps are held in their initial position by a latch 408 and are released when a welt wire is lowered on to the fabric by a transfer member 398, mounted on the picot bar, engaging the latch and enabling the hooks to engage the welt wires. During the take-up operation, the resetting weight is rewound by a pawl and ratchet operated from the main cam-shaft. Specifications 450,440, 480,262 and 598,704 also are referred to.

Title: Systems for use in error detection and/or correction of digital information
Inventor: HELM HARRY ARTHUR
IPC: H04L1/00
Filed: 1965-02-26
Abstract: 1,105,581. Error checking and correcting arrangements. WESTERN ELECTRIC CO. Inc. 26 Feb., 1965 [31 March, 1964], No. 8349/65. Addition to 1,105,583. Heading G4A. An error detecting and correcting system for data transmission comprises means for generating for the data characters of a message two check characters, one check character being generated by an iterative operation on the data characters, means at the receiver for operating on the received data and check character to produce two corresponding error characters and means for operating on the respective error characters so that if identical outputs are produced by the operating means an error correction is effected. The system is such that all single character errors in a message can be corrected and all double and most multiple errors exceeding two can be detected. The operation of the system depends on the particular properties of the " Bose-Chaudhari " codes employed therein. The apparatus is generally similar to that disclosed in Specification 1,105,583, but the first cheek character is generated merely by simple interative modulo-2 addition of the successive data characters in an adder 106, Fig. 1, instead of by an iterative linear operation. The second check character is generated, as before, by an iterative linear operation in a network 108. The transmitted message is of a predetermined length dependent on the particular code employed. At the receiver, Fig. 2, the received message is supplied to a memory 225, such as a delay line, and to check character recalculating circuits 206, 208 which may be identical to the circuits 106, 108 of Fig. 7. The received check characters are added modulo-2 to the recalculated check character, the sum being zero if no error has occurred. At a predetermined time, switches 231, 233 are momentarily closed to transfer the outputs of circuits 206, 208 to circuits 235, 237 which may be identical to the respective circuit 206, 208 and whose outputs are connected to a comparator 239. When the comparator 239 detects equality, a switch 241 is momentarily closed to apply the output of iterative adder 235 to a modulo-2 adder 243 to correct the data character then being supplied by the memory 235.

Title: Improvements in or relating to silicone elastomers
Filed: 1960-03-09
Abstract: An elastomer-forming composition comprises an essentially diorganopolysiloxane in which the organic radicals are monovalent hydrocarbon, halogenated hydrocarbon or cyanoalkyl radicals, and from 0,001 to 0,75 part (by weight) per 100 parts of the siloxane of iron added as ferric hydroxide.  The siloxanes preferably contain terminal Si-bonded hydroxy, alkoxy, acyl or vinyl radicals or H atoms.  The compositions may be cured (1) by heating with organic peroxides, e.g. benzoyl, di-t-butyl and dichlorobenzoyl peroxides and t-butylperbenzoate; (2) by mixing an acid-free diorganosiloxane with an organic silicate in the presence of a metal carboxylate catalyst, as disclosed in Specification 764,246, or (3) in a modification as disclosed in Specification 844,128, using a "Cellosolve" (Registered Trade Mark) silicate as the organic silicate; (4) by mixing a hydroxylated diorganosiloxane with an organohydrogen-siloxane as disclosed in Specification 804,199; (5) by exposing acyloxy-terminated siloxanes to moisture as disclosed in Specification 862,567; or (6) by exposing the compositions to X-rays, g -rays or to U.V. light.  Fillers, e.g. TiO2, Fe2O3, ZnO, asbestos and glass fibres, diatomaceous earth, crushed quartz, and silicas (fume, aerogel and precipitated) per se or surface-modified with organosilyl groups, may also be added.  The De(OH)3 can be added as a dry powder, as a wet paste or as a slurry in alcohols, siloxanes or water.  Examples are given.  Specification 699,759 also is referred to.
