Title: A process for synthesizing polysaccharides
IPC: B01J19/12
Filed: 1964-05-12
Abstract: Polysaccharides are synthesized by mixing gaseous carbon dioxide, activated by irradiation with radiation of wavelength 80-40 <\>rA, and water vapour, activated by irradiation with radiation of wavelength 180-220 mm , with a catalyst consisting of pulverized porous aluminium silicate which has been treated with radiation of wavelength 370-140 mm , irradiating this reaction mixture with radiation of wavelength 370-150 mm , irradiating the product with successive radiations of wavelength 470-370 mm  and 120-60 mm  to form carbohydrate-like substances, and irradiating these substances with radiation of wavelengths 470-20 mm  and 575-647 mm .  In one embodiment, after the irradiation with radiation of wavelengths 470-370 mm  and 120-60 mm , the carbohydrate-like substances are subjected to radiation of wavelength 180-122 mm  before the irradiation with radiation of wavelengths 470-20 mm  and 575-647 mm . The reactions may be carried out in chambers through which the reaction mixture is circulated in quartz pipes, and the radiations may be provided by applying a high voltage to pure quartz tubes, containing small amounts of elements sealed therein in vacuo, fitted in each synthesis chamber.  Specified elements are mercury, selenium, xenon, thorium, lithium, potassium, cadmium and argon in various combinations depending on the wavelengths required.ALSO:In a process for producing polysaccharides by subjecting gaseous carbon dioxide and water vapour to irradiation in presence of a catalyst, a mixer (5) (not shown) is divided into compartments (C), (C\sv), (C\yF) by a rotor (26) supported by shaft (25).  Water vapour and carbon dioxide gas supplied by conduits (28), (29) are fed by the rotor into compartment (C\sv) where the mixture is irradiated, in presence of a catalyst, by radiation of wavelength 80-40  and 180-220mm  emitted from luminous body (27).  The activated reaction mixture is led from chamber (C\yF) by conduit 30 to a series of reaction chambers (not shown) to be further irradiated.

Title: Improvements in writing and imprinting apparatus
IPC: B41J15/24
Filed: 1943-04-14
Abstract: 563,068. Typewriters &c. WILLIAMS, W. P. (Standard Register Co.). April 14, 1943, No. 6002. [Class 100 (iv)] In a writing and billing machine in which record sheets 3 with feed perforations 25 are fed together with carbon sheets attached to a carrier 5 around a platen roll 7 which is mounted in lever arms 8 pivoted to links 9 and is movable from the active position, Fig. 3, to the inactive position, Fig. 4, to permit of the introduction of fresh record strips or cards, or the shifting of transfer material interleaved between the record strips or cards, a device is provided to restrain the movement of the platen roll while in its inoperative position, and this device in Fig. 12 takes the form of a detent 49 which engages the ratchet 47 of the line-spacing mechanism. In the operative position of the platen, a detent 48 functions similarly to the detent 49. In the inactive position of the platen, the record strips are held against movement due to the retractive force of the removed transfer material, and this is accomplished by the automatic adjustment of a cam 24 for controlling the radial position of the feed pins 21 which engage the feed apertures 25. This cam is stationary and normally causes the feed pins 21 to be protruded at the upper part of the feed roller's motion, as shown in Fig. 6, but when the roller 7 is moved to inoperative position, the cam 24 is adjusted so as to cause the pins 21 to be projected from the lower part of the roller and the pins engage the holes 25 to hold the sheets 3 stationary. The cam is moved by bifurcated levers 36 adjustably pivoted to the platen shaft, the levers 36 moving from the position shown in Fig. 6 to that shown in Fig. 9 as the platen is raised, owing to engagement of the levers with bearing collars 39 on the tear-off rod 20 carried by swinging arms 19. In the raised position of the platen the record strips extend rearward in a horizontal line, as shown in Fig. 4, thus relaxing binding tension on the interleaved transfer sheets and permitting retraction thereof. During retraction the record strips are held by engagement of the pins 21 in the holes 25. U.S.A. Specification 1,132,055 is referred to.

Title: Controlled fluid lubricated bearings
Inventor: MOHSIN MOHAMED EZZAT
IPC: F16C29/02
Filed: 1962-02-16
Abstract: 1,027,395. Bearings. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 14, 1963 [Feb. 16, 1962], No. 6188/62. Heading F2A. The rate of flow of fluid from a source 8 to a clearance 1 of a fluid bearing is regulated by a variable resistance which is located between the source and the clearance 1. In an embodiment pressurised fluid supplied from the source 8, Fig. 1 (not shown), enters a conduit 9, passes through an extension 10 of the conduit 9, and through a gap 13, which is formed between an end of the extension 10 and one side of a diaphragm 7; the other side of the diaphragm is urged by a spring 14, one end of which abuts an adjustable screw 15. The conduit 9 is secured at 11 to the body of a chamber 6. In use, the clearance 1 between the faces 2 and 3 is maintained constant and any increase in loading causes a rise of pressure in the chamber 6 so that the diaphragm is flexed, the gap 13 is made wider, and the rate of flow of fluid is increased. Similarly, a decrease in loading reduces the rate of flow of fluid, the diaphragm being urged by the spring 14 so as to reduce the gap 13. In a modification, a conduit 25, Fig. 2 (not shown), is supported by, and is secured to, a diaphragm 29, and an extension of the conduit passes through the diaphragm and forms a gap 40 with an adjustable member 39. In other modifications, the diaphragm is replaced by a stiff disc supported by seals which also serve to allow a limited displacement of the disc; and two discs are interconnected and act to regulate the flow of fluid when a bearing is subjected to negative loading.

Title: Improvements in or relating to gramophone record changers
Inventor: COSTA HARRY DA
IPC: G11B17/16
Filed: 1956-02-29
Abstract: 817,509. Automatic gramophones. PLESSEY CO. Ltd. Dec. 28, 1956 [Feb. 29, 1956], No. 6349/56. Class 40 (2). In a record changer having a feeler member which is differentially actuated by differentsized records for controlling the setting-down position of the stylus, said feeler member is utilized for controlling the speed at which the turntable is driven. The embodiment is directed to means for playing mixed 33 1/3 r.p.m. and 45 r.p.m. microgroove records and takes advantage of the fact that 45 r.p.m. records are 7 inches in diameter. The apparatus is provided with means for manually setting the speed at 78, 33 1/3 or 16 r.p.m., but when set for 33 1/3 r.p.m. the speed is automatically changed to 45 r.p.m. if a 7-inch record falls to the turntable. The feeler member may be a toothed sector-shaped plate 16 as shown in Fig. 4, which assumes one of three different positions, according to whether a 7-inch, 10-inch or 12-inch record falls to the turntable 8, and rotates a shaft or pin 21 having an ear 11 which is thereby set in the path of teeth 13, 14 or 15 on a lever 6 secured to the shaft of the pick-up and controlling the setting- down position of the stylus in well-known manner. The three alternative speed positions are set by rotation of a shaft 48 bearing a disc 36 having three notches 37, 38, 39 arranged at progressively increasing radial positions and which are engaged by a follower 34 on a lever 30 pivoted at 29 on a bar 26 and acting on a spring- loaded rod 31 controlling a speed-changing means 32. The notches 37, 38, 39 correspond to speed settings of 78, 33 1/3 or 45, and 16 r.p.m. respectively. When set to notch 38 and a 7-inch record falls to the turntable, the lever 6 is swung to the extreme position in which a pin 25 thereon moves the bar 26 about pin 28 and produces additional movement of lever 30 and sets the speed-changing means from 33<SP> 1</SP>/ 3  to 45 r.p.m. Return movement of lever 6 at the end of a record causes the bar 26 to be restored to its initial position by the engagement of a pin 25a with a sloping surface 49 on the bar 25. The additional movement of lever 30 is prevented when disc 36 is set for 16 r.p.m., by means of a pin 43 thereon which engages the hooked end 44 of bar 26. A similar pin and hook may be arranged for the 78 r.p.m. setting, but this is not shown in the Figures. Specification 817,510 is referred to.

Title: Improvements in or relating to the manufacture of chlorinated organic compounds
IPC: C07C37/62
Filed: 1943-04-21
Abstract: Dichlorophenol is made by subjecting molten phenol to the action of chlorine until a reaction product containing dichlorophenol is formed having a maximum setting point.  This is found by taking samples of the material undergoing chlorination and determining their setting points, 37 DEG  C. being the maximum. The setting point may be correlated with the density at a given temperature, thus chlorination to a setting point above 34 DEG  C. corresponds to chlorination to a density at 40 DEG  C. between 1.4 and 1.42 gm. per ml.  The product is distilled to isolate a fraction consisting of 2,4-dichlorophenol.

Abstract: 151,538. Wade, H., (Lockwood, L. V.). March 4, 1920. Pressing.-Relates to a machine for making the necks of carboys and large glass containers with internally-screwed mouths, and consists in forming the mouth by pressing a charge of metal on to the hot neck of the carboy immediately after it is removed from the mould. The machine comprises a table A on which is mounted a neck mould consisting of a lower section 2 which is firmly secured to the table, and two upper sections 3 which are hinged to the section 2 and can be opened and closed by a sliding rod 7 operated by a pedal. The upper sections 3 have extensions 3<b> which are formed with a cylindrical cavity 6 adapted to hold a charge of metal. A pressing- plunger 17 is operated by a fluid-pressure cylinder 18 mounted on a carriage 24 that can be moved backwards and forwards along guide bars 25 by means of a hand lever 32. The threaded plug 11<c> that forms the interior of the mouth of the carboy is attached to a mandrel C which slides through a bearing 8a and both slides through and screws into a bearing 9<a>. In use, the mandrel is screwed into the bearing 9<a> by means of a handwheel 13 so as to project the plug 11<c> into the mould, and the press cylinder 18 is moved into the position shown in dotted lines in Fig. 1, so that the forward ends of cams D<3>, Fig. 2, engage the extensions 3<b> of the mould and thus lock the mould. A carboy is removed from the mould in which is has been blown, and while the neck position is still hot, has its neck forced into the mould as shown. A charge of metal is then dropped into the mould cavity 6, the cylinder is moved into position above the mould and compressed air is admitted so that the plunger 17 is forced into the cavity and presses the metal around the plug 11<c> to form the mouth of the bottle. The plunger is then withdrawn, the handwheel 13 turned to screw the plug 11<c> out of the mouth of the bottle, the press cylinder moved rearwardly, and the mould opened.
