Title: Method of preparation of 3-methylene-cephams
IPC: C07D403/12
Filed: 1975-12-18
Abstract: 3-Methylenecepham 1-sulphoxides of the formula <IMAGE> in which the substituents are defined in Claim 1 are prepared. These compounds are prepared by bringing about ring closure in a corresponding sulphinylazetidinone of the formula <IMAGE> in which X is chlorine or bromine, an alcohol or thioalcohol residue, an ester or a thioester residue, or an amino radical. If X is chlorine or bromine, the compound II is reacted with a Friedel-Crafts catalyst of the Lewis acid type, with a Friedel-Crafts catalyst of the Bronsted protonic acid type or with a metathetical cation former in a dry inert organic solvent, or is dissolved in an organic Bronsted acid. If X in compounds II is an alcohol, thioalcohol, ester or thioester residue or an amino radical, reaction is carried out with a Friedel-Crafts catalyst of the Bronsted protonic acid type in a dry inert organic solvent, or the compound is dissolved in an organic Bronsted acid. The resulting compounds can be used for the preparation of cephem antibiotics.

Title: Borehole orientation tool
IPC: E21B47/024
Filed: 1970-11-03
Abstract: 1314354 Position sensing apparatus SUN OIL CO 3 Nov 1970 [21 Nov 1969] 52134/70 Heading G4H [Also in Division H4] The angular disposition of an instrument housing in a borehole is digitally determined by determining the azimuthal orientation of the housing and the inclination of the housing with respect to the earth's surface. As described the inclination of housing 27 (Fig. 2) is determined relative to a first vertical reference plane utilizing a scanning disc 39 supported by the housing and rotated via gears by a motor 16. A pulse is generated when a lamp 48 carried by the disc illuminates a photocell 64 fixed to the housing to set a bistable (106, Fig. 4, not shown). The bistable is reset by the pulse from a second photocell 53 (carried by the disc) when it is illuminated by the lamp 48 via a slit in a shield 59 of a weighted pendulum member 63, the position on the slit depending on the direction of the gravitational force. Similar apparatus is utilized to determine the position of the housing relative to a second vertical reference plane 90 degrees from the first. The directional orientation of the housing is similarly determined utilizing a scanning disc (86, Fig. 3, not shown) and shield (74) except that the shield is positioned by a directional gyroscope (181) the outputs of photocells (88, 94) setting and resetting a gyro bistable. The motor driving the scanning disc (86) also drives an encoder delivering pulses to three gates (1, 2, 3, Fig. 4, not shown) so that the times for which the two pendulum bistables and the gyro bistables are set are measured by counting. A vector summation of the counts corresponding to the angular position is made. The count corresponding to the directional orientation representing the azimuthal degrees between Magnetic North and the reference photocell on the housing represents the angle through which the vector summation should be rotated to give the angular disposition of the housing relative to Magnetic North. The result may be printed or otherwise recorded.

[Also in Division F2] A self-locking and self-sealing fastener having a threaded portion provided thereon with a patch of thermoplastic material is made by heating a threaded member 110 to a temperature above the melting temperature of the thermoplastic material, depositing upon a selected area of the thread of the heated member 110 a quantity of thermoplastic material in fine powder form while rotating the threaded member about its longitudinal axis, at least a portion of the thermoplastic material being melted by the heat of the threaded member and adhering thereto and to the unmelted portion of the thermoplastic material, and thereafter cooling the thermoplastic material to provide a cohesive patch of solid thermoplastic material bonded to the thread. As shown, the threaded member is mounted in a holder 151 which is driven by a pulley 152 and belt 153 to cause rotation of the member by 200‹ to 360‹. A hopper 155 having an outlet 156 contains powdered thermoplastic material which, after the threaded member has been cleaned by a weak solution of acid, heated to a temperature of 500‹F to 550‹F and mounted in the holder 151, is directed to a small area of thread. The threaded member is then transferred to a support plate 161 within the field of an induction heating coil 162 which is operated to fuse the thermoplastic material on the threaded member to the thread before the thermoplastic material is allowed to cool. The thermoplastic material which may be nylon or a vinyl or polypropylene resin may contain from 0.1% to 5% by weight of molybdenum disulphide and the threaded member may, before the thermoplastic material is applied, be provided, e.g. by a dipping and baking process, with an epoxy or phenolic resin coating to improve adhesion between the thermoplastic material and the thread.

As shown collector 28 is a J box and means 174 is a tube having an internal cross sectional area 1¢ to 2 times the area of the outlet as defined by arch 178, Fig. 10, and a diameter slightly greater than the largest dimension of the outlet from chamber 22. This prevents buckling of the yarn. Tube 174 bends through 90‹ to direct the yarn to the J box, the bend serving to axially compress the yarn. Further axial compression is provided by a weak leaf spring 190 near the J box end of the tube. The J box has a cross-section of 0.5 to 0.9 in<SP>2</SP> per 100 deniers of yarn to prevent the toppling over of a pile of yarn (Figs. 2A-2C, not shown) as happens in larger diameter J boxes. The yarn is first heated in section 30 then cooled in section 32 of the J box as it passes through in an untensioned condition to heat set the crimps. Steam is passed into the plenum chamber formed by housing 102 and the concentric wall (104, Fig. 6) of the J box and passes through apertures 110, 112 to heat the yarn. Similarly ambient air is passed to plenum chamber (124, Fig. 7) formed by housing 120 and passes through apertures 128 to cool the yarn. The heating and cooling sections are of substantially the same diameter and are free from obstructions. Yarn movement, tangle removing. Yarn 12 is fed from a supply package to driven godet roll 16 and separator roll 14 then to godet 20 and separator 18, the latter rolls rotating faster to draw the yarn which may be heated by godets 16, 20. The yarn is then bounce crimped at 22 and passed to J box 28 as described. The heat set texturised yarn is drawn over baffle 48 and through an eyelet 50 to remove gross tangles. Tension vanes 52, 54, 56, 58 comprising thin metal sheets pivoted at hinges 60, 62, 64, 66 pinch the advancing yarn gently to further remove tangles. The yarn is pulled over idler rolls 34, 36, 38 and godet rolls 40, 42 and wound up in package 46. When the yarn piles up in J tube 28 above light source 132 light is not received by sensor (134, Fig. 8, not shown) and the rate of rotation of godet rolls 40, 42 is slowed until the volume of yarn decreases and light is received by sensor (134).

The protuberances may comprise spacers, e.g. 12, 13, 14 mounted on those individual conductors 8, 9, 10 which do not comprise superconductive material and may be conductive, insulating, or both, or a spacer may include both conductive and insulating material. Insulating spacers obviate the requirement for providing insulating material between the turns of a winding. The spacers may be spot welded and have ribs whereby they are pressed into apertures 17 in the individual conductors. As shown they may or may not overlap adjacent individual conductors. Apertures 16, 18 are for circulation of coolant. Recesses in the conductor may result from the super-conductive individual conductors being  thinner, e.g. conductor 26, or it may have a longitudinal groove 31 as in conductor 25 or both means may be utilized as in conductor 27. Alternatively these individual conductors may be thicker with transverse channels milled out to the level of the other individual conductors. The superconductive wires 2 may be embedded in copper or aluminium. The non-superconducting individual conductors may be steel. Instead of a single individual conductor spacing pairs of individual conductors including super-conductive material, a row of spaced apart short individual conductors may be employed.
