Filed: 1920-07-16
Abstract: 162,975. Goold, L. W., (Fulton Iron Works Co.). July 16, 1920. Roller mills.-In cane mills or crushers having rolls with peripheral ribs and grooves, the ribs and grooves terminate at abrupt shoulders to prevent lateral displacement of the material at the ends of the rolls. The grooves at the ends of one roll are provided with walls which form abrupt shoulders, while the other roll is provided with end ribs to confine the material in the corners formed by the abrupt shoulders. As shown, the upper and lower rolls A, B have end ribs 4, 6 of less depth than the intermediate V-shaped ribs 3, and end flanges 7 of the lower roll overlap the ends of the upper roll. Each of the end grooves 5 of the lower roll has a base wall 8 parallel to the axis of the roll, an outer side wall approximately at right-angles to the wall 8, and an inner side wall 10 at an obtuse angle to the wall 8. The end ribs 4 of the upper roll conform to the shape of the end grooves 5 and the shoulders formed by the walls 9 tend to prevent Lateral displacement of any material forced into the grooves 5 The intermediate ribs 3 may be notched as at 11, but the end ribs 4 are comparatively smooth. To minimize the delivery of cane to the end grooves 5, baffles 12 are arranged at the intake side of the rolls. Each baffle has an arcuate lower edge situated in an end groove 5 and contacting with the base wall 8 of the groove, and an upper arcuate edge conforming to and contacting with the smooth periphery of an end rib.

Title: Process for the production of derivatives of androstenols
IPC: C07J1/00
Filed: 1935-02-06
Abstract: Androstenolone compounds in which the hydroxy group is replaced by a group which on hydrolysis is reconverted into a hydroxy group are subjected to the action of reducing agents under such relatively mild conditions of temperature and pressure that the double bond present in the nucleus remains substantially unaffected.  Reducing agents which are suitable include amalgams, such as aluminium amalgam, and hydrogen in the presence of Raney nickel catalysts.  In examples: (1) water is allowed to drop slowly into an ethereal solution of dehydroandrosterone acetate and aluminium amalgam.  The sludge of aluminium hydroxide is filtered, the ether evaporated, and the androstendiol - 3 - acetate recrystallized from methanol or hexane; (2) dehydroandrosterone acetate is shaken at room temperature with hydrogen in the presence of a Raney nickel catalyst, until one molecular proportion has been absorbed.  The catalyst is filtered off and the mono acetate of androstendiol recrystallized. Specifications 346,130, [Group VI], 443,463, and 455,018 are referred to.

Title: Seismic exploration method
IPC: G01V1/28
Filed: 1973-05-07
Abstract: 1394533 Seismic prospecting CHEVRON RESEARCH CO 7 May 1973 [5 May 1972] 21732/73 Heading H4D In a marine seismic prospecting system a seismic source and hydrophone streamer are moved by a single boat which traverses a straight course line, the trailing end of the streamer has a steerable paravane assembly so that the trailing end moves along a line parallel to but offset laterally from the course line, and the instantaneous positions of the hydrophones relative to the boat are determined by digitally timing the travel of sonic pulses from a transmitter aboard the boat to a series of target transducers on the streamer. The trailing end offset results in successive locations of the hydrophones and source point defining a twodimensional grid of centre points (where each centre point is mid-way between a source point and associated hydrophone location) which can be arranged to give three-dimensional common depth point coverage of the subsurface. The hydrophone position determination preferably occurs between actuation of the seismic source and receipt of the resulting seismic reflection signals. The determination involves counting clock pulses and recording the counts on a header portion of a magnetic tape. The seismic reflection data, together with recording amplifier binary gain, navigational and other data, are then recorded on the tape in digital format (details given), the reflection data from individual hydrophones being multiplexed prior to conversion to digital form. For subsequent computer processing of the seismic data the counts recorded on the header portion are combined with the navigational data to derive the absolute (geodetic) positions of the hydrophones so that the centre point grid can be associated accurately with the subsurface.

Title: Improvements in or relating to the spinning of synthetic linear polymers
IPC: F23D14/48
Filed: 1953-08-07
Abstract: <PICT:0741342/IV(a)/1> <PICT:0741342/IV(a)/2> <PICT:0741342/IV(a)/3> A molten synthetic linear polymer is extruded from a spinneret to form one or more filaments which are passed, before being wound into a thread package, through an elongated space at the boundary of which there is caused to flow a stream of liquid, this liquid being exposed to any gases or vapours given off by the extruded filaments.  The stream of liquid absorbs volatile monomer fractions which are evolved from the filaments.  Preferably the liquid flows within a space bounded externally by a sheath and in this case the liquid prevents the air enclosed by the sheath from becoming overheated, A screen may be positioned between the filaments and the liquid, the openings in the screen having a sufficient overall area not to obstruct the passage of gases or vapours to any significant extent.  The liquid may be in part re-cycled so as to obtain a more concentrated solution of monomer fractions and thus to facilitate recovery of the monomers. The polymer may be a polyamide obtained from caprolactam or amino-caproic acid and the liquid used for absorbing the vapours of monomers during the production of the filaments may be water. As shown in Fig. 1, filaments 11 are extruded from spinneret 10 and pass downwardly through a tubular sheath 12 to rollers 14 and bobbin 13. A metal net 16 is located within the sheath and a film of water 17 is kept constantly flowing between the sheath and the net.  The water, which has absorbed monomer fractions, collects in a basin 21 from which it is discharged through pipe 22.  A portion of the liquid is recycled by means of the pump 20 and pipe 19, and the rest is continuously drawn off through pipe 24 and conveyed to a recovery apparatus.  As shown in Fig. 2, Raschig rings or like elements 30 are disposed between sheath 12 and net 16 to permit the formation of a water film of large surface area. A pipe 31 is located internally of the net 16 and has holes of considerable overall area to permit easy passage of vapours therethrough.  As shown in Fig. 3, several spinning nozzles are located near to one another and several bundles of filaments 11 are formed.  A perforated pipe 31 is placed in correspondence to each filament bundle.  A single sheath or casing 40 for all the filament bundles is employed and the Raschig rings 41 are positioned within the casing and held in place by longitudinal nets 42.  Perforated tubes parallel to the nets, acting as shower nozzles (not shown), are located at the top of the casing 40, and the water collects in the basins 43.
