Abstract: 127,444. Wentz, J. L. July 12, 1918. Portable flat endless-belt conveyers and elevators; adjustably supporting; driving-gear; feeding- devices; band-retaining devices; casings, elevatorboots, troughs, and the like; guiding; idler rollers; guards and shields to prevent falling-off and spilling; stationary cleaners and clearers and antifouling guards; swinging plates to prevent running back of material; tensioning belts.-A portable conveyer for transferring coal &c. from a heap to a vehicle is provided with a loosening-device for the material which is actuated by the idler drum 30 supporting the conveyer belt 28 at the receiving-end of the conveyer. The drum 30 is disposed within a casing comprising a shoe plate 31, nose-piece 44, flexible apron 32, and side plates, and a cam 45 is mounted on its shaft without the casing. This cam bears against the ground or against a bar 46, Fig. 5, driven into the ground, and, by its rotation, the casing is moved to break up the material, which is further agitated on its passage to the belt by the movement of the apron 32 caused by the transverse rubber strips 38 mounted on the belt. In a modification, the shaft of the drum 30 is fixed in a boss 50, Fig. 7, on a plate 49 which is connected by a pivot 51 to a slotted disk 47. The other end of a plate 49 is connected by a pin 52 to any one of a series of sockets 53 in the disk 47. The slot 48 and sockets 53 are concentric with the pivot 51. By varying the point of connexion of the pin 52 and disk, the vibratory action of the casing is varied. The frame of the conveyer is constructed of angle-bars 24, 25, Fig. 3, maintained parallel by braces and cheek-plates 27. The belt 28 runs between boards 37 and rests on rollers 35 and rails 36. Running-back of the material is pre. vented by pivoted plates 55. Any material which may reach and adhere to the drum 30 is removed by a scraper 58, Fig. 4, supported by an angleiron 59, which acts as a scraper for the belt. The scraper 58 is also supported by a block 60 which has a scraping-edge and supports inclined shelves 61. Material removed by the scraper 58 is delivered on to the shelves 61, which direct it to the outside of the frame. The framework is connected by cross-bars to standards 18 and bars 21. The standards are slidably mounted in sleeves 17 and connected thereto by pins engaging any one of a series of perforations 19. The bearings 16 for the axle of the wheel 15 extend bracketwise from the sleeves 17. The ends 22 of the bars 21 are formed as sockets for the handles used in propelling the apparatus. These handles may also be used as the bar 46, Fig. 5. The driving-drum 29 is mounted in bearings in sliding blocks 33 which are adjusted by screws 34, and is driven from a motor 40 by chain-and-sprocket gearing.

Title: Process for producing adipic acid and a ketone oxime
IPC: C07C55/14
Filed: 1961-03-29
Abstract: Adipic acid and a ketoxime are prepared by reacting cyclohexanol with adipomononitrolic acid, reacting the resulting adipomonohydroxamic acid with a ketone, and separating adipic acid and the oxime of the ketone from the reaction mixture. Specified ketones are cyclohexanone, acetone and methyl ethyl ketone.  A preferred procedure comprises (1) reacting adipomononitrolic acid with cyclohexanol to produce adipomonohydroxamic acid and cyclohexyl nitrite and distilling off the latter; (2) heating the adipomonohydroxamic acid with the ketone to produce adipic acid and the ketoxime; (3) neutralising with an aqueous base, extracting the ketoxime with a non-aqueous solvent, and crystallising adipic acid from the aqueous phase; (4) oxidising the cyclohexylnitrite with nitric acid to form adipomononitrolic acid and nitrous acid; (5) recycling the nitrolic acid to step (1); and (6) oxidising the nitrous acid with air and recycling the nitric acid to step (4).  If cyclohexanone is used as the ketone, steps (1) and (2) may be carried out concurrently by using a cyclohexanol/cyclohexanone mixture obtained by the liquid-phase air oxidation of cyclohexane. Adipomononitrolic acid may be prepared by reacting cyclohexanone with nitric acid containing at least an equimolar quantity, based on the cyclohexanone, of NO2; the NO2 may be supplied by carrying out the reaction in the presence of cyclohexyl nitrite.  Adipomononitrolic acid is also prepared by the action of nitric acid on cyclohexyl nitrite.  Specification 633,354 is referred to.

Abstract: 1,041,681. Transistors. WESTINGHOUSE ELECTRIC CORPORATION. March 18, 1965 [March 20, 1964], No. 11548/65. Heading H1K. In a transistor formed by the planar process a highly doped part of the collector region is connected to the top surface of the wafer by a highly doped " wall ". As shown, N<SP>+</SP> and N- type layers 112, 113 are provided on a P-type substrate 110 by epitaxial deposition or by diffusing arsenic into substrate 110 to form layer 112 and then epitaxially depositing layer 113. P-type impurity is deposited on the surface of layer 113, using a photolithographic technique to form an oxide mask, and is then driven through layers 113, 112 to form P type region 116 which surrounds and isolates part of the wafer which is to form the transistor. N-type impurity, such as phosphorous, is deposited inside this region so that during the subsequent diffusions of base region 118 and emitter region 120 it is driven through layer 113 to form N<SP>+</SP> type region 122 which contacts layer 112. Since N-type impurity diffuses faster than P-type impurity into an N-type region, region 122 is driven further than region 118 and may even reach layer 112 at this stage. Aluminium contacts 123, 124, 125 are applied to emitter region 120, base region 118 and collector region 122 respectively through apertures in an oxide layer 115. The base and collector contacts may have gaps through which deposited conductive strips may pass to connect the transistor to other components of an integrated circuit produced in the wafer. Region 122 may also be produced at the same time as region 116 by depositing the N-type and P-type impurities and then driving both into the wafer.

Abstract: 582,840. Aerial marine torpedoes. BURNEY, SIR C.D. April 19, 1939, Nos. 11744/39, 1996/40 (divided out of 582,842), 1997/40 (divided out of 582,843), 1998/40 (divided out of 582,842) and 1999/40 (divided out of 582,844). [Class 9 (ii)] [Also in Groups XXIX and XXXIII] A marine torpedo, having aerial supporting surfaces and adapted to execute gliding flight when launched from aircraft, is provided with means to cause automatic removal of the supporting surfaces before the torpedo strikes the water and at a predetermined height above the water. The invention also includes the combination with the means for automatic removal of the supporting sunfaces of gyroscopic or other automatic control means for the gliding flight as described and claimed in Specification 582,845. Fig. 2 shows a torpedo 1 after release from the carrying aircraft, the detachable wings 2 being provided with a trailing paravane 7 which strikes the water and, travelling evenly below the surface of the water, exerts a pull to effect automatic removal of the wings before the torpedo strikes the water. The torpedo is also provided with a tail attachment 3, retained by a cable 6, and having elevators 4 and rudders 5 for controlling roll, direction and angle of glide during aerial flight, the attachment being removed by aerial or water drag. As shown in Fig. 5, the control of the rudders 5 and of the ailerons 21 on the elevator 4 may be effected by the gyroscopically-con- , trolled rudder 16 of the torpedo itself, or, as shown in Fig. 19, by servomotors 43 controlled by a separate gyroscope 44, the power being derived from a wind vane 10 driving an oil pump 42. The torpedo 1 and the paravane 51, Fig. 6a, are supported from the aircraft by cables 35, 77 under the control of release hooks 76, 79. The wings 2 are connected to the torpedo by a strap 15 secured at the bottom by a bolt 32 which is rotated by the pull of the paravane to cause release by the device shown in Fig. 10, 41 being a shearable bolt which causes the arm 33 on the bolt 32 to fall to the dotted-line. position. The paravane, Fig. 12, is in the form of a miniature inverted aeroplane with wings 54 and tail 56, the cable 8 passing over a drum 58 having braking means. The paravane is constructed in halves connected by bolts 52. The gliding control of the torpedo may be effected by ailerons c on the wings 2, Fig. 18, which are controlled by a gyroscope 44 or by mercury-oscillators. Fig. 16 shows a torpedo 1 with wings 2 and tailpiece 3 automatically released, just before the torpedo strikes the water, by the impact of a forward projection a which serves to shear a pin band turn the bolt holding the strap 15. Means for releasing the torpedo clear of the slip stream of the carrying aircraft is illustrated in Fig. 20 (not shown). Specifications 582,841, 582,842 and 582,844 also are referred to.

Filed: 1926-05-04
Abstract: 274,978. Potter, H. S. May 4. 1926. Drawings to Specification. Cased forms; tubes.-In making hollow bars or rods such as mining drill steels from hollow billets, a metal lining is united by a spraying operation or by electro-deposition to the bore of the billet prior to rolling into bar form so as to protect the surface of the bore from damage during subsequent rolling by the mandrel, sand core or metal core methods and also to prevent rusting of the finished drill by water in the mines. The lining may consist of copper, nickel. or rustless steel or iron. The bore is first cleaned by sand blast and mav then be coated by metal from a spraying nozzle on an arm rotated by a turbine, the nozzle being inclined to the arm or being provided with a deflector plate. The thickness of the lining may be rendered uniform by reaming or pressing by a polishing operation e.g.- by pushing a mandrel or ball therethrough. Any cracks formed during the rolling operation may be removed by relining the bar by electrodeposition. A nickel lining serves as a lubricant to facilitate rolling on a mandrel or withdrawal of a metal core. A finished steel may be sprayed with a bitumen paint and deposits of silica therein may be removed by a jet of compressed air.. Specification 208,777 is referred to.
