Title: Improvements in methods of and apparatus for making paper
Inventor: LEE CHARLES ALLEN
IPC: D21F9/02
Filed: 1960-04-22
Abstract: 931,196. Making paper. HUYCK CORPORATION. April 22, 1960, No. 14284/60. Class 96. Paper is made by delivering a flowing stream of a stock suspension of papermaking fibres to a continuously moving, elastic, foraminous carrier formed of synthetic fibre and capable of substantial elastic extension, draining sufficient liquid from the suspension on the carrier to form a wet web of fibres, conducting the wet web on the carrier through at least one resilient nip, applying sufficient pressure to produce momentary elastic deformation, e.g. extension, in corresponding portions of the web as the carrier and the web are pressed in the nip, to remove liquid from the web, and drying the web. The resilient nip is a pressure nip between two contacting surfaces, e.g. of parallel rolls, at least one surface being deformable and of a resilient material which is substantially non-compressible. As shown, pulp from a flow-box 10 is carried by a forming conveyer 12 of synthetic fibre capable of substantial elastic extension over table rolls 16 or over suction-boxes (not shown), and through the nip of a wet press 19, 20 the lower roll 20 of which is rubber-covered and may be a suction roll, in which case the rubber cover is perforated. The nip may also have a second forming fabric or a felt 21 passing through it. The roll 19 may be plain or rubbercovered. The wet-pressed web is taken to a Yankee-dryer drum 24 which may coact with one suction roll (23) or with two (23 and 25). The dried web is creped from the drum by the doctor knife 28 and wound up at 30. Spreader rolls 29 prevent wrinkling of the forming fabric. In modifications (a) the wet press 19, 20 acts as a couch press and a felt or fabric carries the web to the suction-roll-and-Yankee-drum press, and (b) the web passes via a succession of press rolls to a multi-drum dryer. The synthetic fibre of the forming carrier may be a polyamide, a polyester, an acrylic fibre or a polymeric vinyl fibre.

Abstract: 677,979. Pick boxes. MUSCHAMP, N. J., and COWLISHAW, F. Aug. 31, 1949. [Sept. 1, 1948] No. 14325/51. Divided out of 677,886. Class 68 (i). In a pick carrier assembly for a mining machine, the pick 9 in the form of a star wheel is rotatably mounted on a bearing 10 the square ends 11 of which project beyond the wheel and fit into correspondingly-shaped apertures 12 formed in the upper edges of the inner member 6 of the box assembly. An outer member 3 secured to the inner member, such as by welding, masks these slots and a pivot 15 passes through the outer member and the bearing to secure the star wheel in position. The configuration of the outer member of the box assembly and the manner of mounting the box assembly on a carrier form the subject-matter of Specification 677,886. Specifications 614,865 and 623,346 also are referred to.

Title: Improvements in or relating to fluid-controlling valves
Inventor: HOYLE EDGAR
IPC: F16K5/22
Filed: 1962-04-13
Abstract: 1,004,565. Valves. AUDCO Ltd. May 10, 1963 [April 13, 1962], No. 14328/62. Heading F2V. A rotary tapered plug valve is provided with means for feeding lubricant to urge the plug towards the larger end of its seating and means for feeding lubricant to parts of the interengaging surfaces of the plug and seat which are on the downstream side when the valve is closed. In the embodiment shown in Fig. 3, lubricant is fed through a passageway 14 in the spindle and through a passage 17 to a chamber 16 to urge the plug 10 against a spring 9. Lubricant is also fed to radial passages 18 containing non-return valves 19 and, when the valve is closed, lubricant flows past the valve on the downstream side to recesses 20 in the housing, through grooves 21 to recesses 22 and to groove 23 thereby lubricating the surfaces. The grooves 23 are separated by portions 24 which prevent communication between the grooves except when the valve is in the open position. Leakage of fluid on the upstream side acts on the associated non-return valve 19 to prevent flow of lubricant. Nipples 25 may be provided to supply lubricant to the interengaging surfaces. In a modification the non-return valves 18 act in the opposite direction providing the lubricant supply to the chamber 16 from the nipples 25 thus dispensing with the supply in the spindle. In a further modification, Fig. 6, the lubricant is controlled by a valve 33 which is subjected to upstream and downstream pressures through conduits 34, 35. As shown the passage 36 is the upstream side and the valve 33 has been moved to the right to permit flow of lubricant through conduit 38 to supply the interengaging surfaces on the downstream side when the valve is closed. In a further modification the valve 33 is located in the valve plug 10 and controls the lubricant fed from the spindle.

Abstract: 271,911. Lorenz Akt.-Ges., C. Feb. 3, 1926, [Convention date]. Atmospherics and undesired signals, eliminating or limiting ; duplex signalling. -In a receiving system the aerial circuit is divided into two parallel branches the currents in which are differentially combined in the receiving circuit F and in one of the branches a series combination of inductance L and capacity C is provided constituting an acceptor circuit to the frequency to be eliminated. The Figure shows such a circuit with a resistance R in the second branch to enable the balance to be obtained in amplitude. The output instead of being coupled may be directly across the inductances L1, L2 and the amplitude balancing can be obtained by varying the couplings K1. L1 and E2. L2, and by dimensioning the additional apparatus in the twobranches. The arrangement is adapted for simultaneous transmission and reception. In the case where a single aerial is employed the transmitter is coupled to the aerial outside the branching off connection and the receiver is electrostatically shielded. A number of disturbing waves may be eliminated by arranging a number of circuits in cascade each having its acceptor circuit tuned to one of the disturbing frequencies.

Title: A process for the manufacture of deltatocopherol
IPC: C07D311/72
Filed: 1961-04-25
Abstract: Delta tocopherol is made by diazotizing 4-hydroxy-3-methyl-aniline in an acidic medium, converting the resulting diazonium salt into the corresponding monoacyl derivative by reaction with an alkanoic acid containing up to six carbon atoms, condensing the monoacyl derivative in the presence of an acid condensing agent with iso-phytol or phytol and hydrolysing the condensation product.  Diazotization may be effected at 0-5 DEG C. in the presence of an alcohol or glacial acetic acid and hydrochloric or sulphuric acid using isoamyl nitrite or sodium nitrite.  The diazonium salt is then heated to 50-80 DEG C. in the presence of acetic or propionic acid and then condensation is effected with isophytol or phytol in the presence of zinc chloride or boron trifluoride diethyl etherate at a temperature below 40 DEG C. The hydrolysis step may be effected by means of sulphuric acid in the presence of dioxene, or by reaction with lithium aluminium hydride or a Grignard reagent.

The acids specified are formic, acetic, and lactic, and mixtures of these.  The salts may be obtained by direct reaction between basic nicotine and the acid; or tobacco juice may be rendered alkaline to set free the nicotine base which is then extracted with paraffin and the extract so obtained treated with the acid.  The salts formed, which are insoluble in paraffin, are separated by decantation.  Reference is made to salts of nicotine with higher fatty acids, but these are stated to be unsuitable on account of their solubility in paraffin.ALSO:Insecticidal or anti-cryptogamic products contain as the active material salts of nicotine with saturated monobasic carboxylic acids having a saponification factor above 620.  The acids specified are formic, acetic, and lactic or mixtures of these. According to examples a liquid product contains nicotine formate and a wetting agent such as oxgall or its derivatives, and a solid preparation contains nicotine formate, a mixture of capric and lauric acids obtained from cocoanut or palm oil, and carbonate of soda.  The salts may be obtained by direct reaction between basic nicotine and the acid, or the acids in question may replace sulphuric acid in the known method for obtaining nicotine sulphate.  According to an example tobacco juice is rendered alkaline to set free the basic nicotine which is then extracted with paraffin.  The separated paraffin solution is then treated with formic, acetic or lactic acid, and the salt formed, which is insoluble in paraffin, is separated by decantation.  Reference is made to salts of nicotine with higher fatty acids, but these are stated to be unsuitable on account of their solubility in paraffin.
