Title: Improvements in or relating to the acylation of 7-aminocephalosporanic acid and derivatives thereof
Inventor: WETHERILL LEWIS AUBREY
IPC: C07D501/06
Filed: 1964-05-28
Abstract: A process for the acylation of 7-amino-cephalosporanic acid, or an acid addition salt thereof, by means of an acyl halide to yield 7-acylamidocephalosporanic acid comprises effecting the acylation under substantially anhydrous conditions in the liquid phase in an inert Lewis base having a dielectric constant above 15 and containing a hydrogen halide acceptor, the reaction mixture not being subjected to ultrasonic vibrations.  The hydrogen halide acceptor may be (a) an appropriate Lewis base, which may be used as such or may be used in addition to another Lewis base; or (b) an alkali metal or alkaline earth metal carbonate or bicarbonate or a tertiary aliphatic amine e.g. triethylamine.  Typical Lewis bases are N,N-dimethylformamide, N,N-dimethylvaleramide, N,N-dimethylpropionamide, N-formylpiperidine, N-formylmorpholine, dimethylsulphoxide, N,N-dimethylcyanamide, N,N,N1,N1 - tetramethylurea; a mixture of acetonitrile and triethylamine being preferred. It is preferred to use 7-ACA in the form of the hydrogen p-toluene sulphonate salt.  A very wide range of acyl groups may be introduced by this method.  7-ACA may be replaced by <FORM:1104937/C2/1> where X is an azide, s-thiobenzoyloxy, 4-methyl - pyrimidyl - 2 - thio, 4,6 - dimethyl pyridyl-2-thio or other groups derived from a nucleophile as in Specifications 1,012,943 and 1,059,562. Reference is made to U.S.A. Specification 3,079,314 wherein a similar acylation is carried out in the presence of ultrasonic vibrations.

Abstract: 757,508. Toothed gearing. NAPIER & SON, Ltd., D. July 22, 1954 [Aug. 17, 1953], No. 22639/53. Class 80(1) [Also in Group XXXIV] In epicyclic gearing comprising a driving or driven sun-wheel H2, Fig. 2, a reaction annulus G, and a driven or driving spider C carrying three or more stepped planetary gear pairs E1, E2, one end of a shaft H integral with the sun H2 is floatingly supported by a resiliently-mounted bearing K allowing radial movements to ensure even distribution of load between the planet assemblies. The other end of the shaft H is loosely splined to a shaft B and is supported in a ball bearing J permitting limited self alignment. The annulus G may also be resiliently supported. The gearing may be employed in aircraft or marine propulsion and as shown comprises reduction gearing between a quill shaft B connected to the rotor of a gas turbine, and a propeller shaft A. The shaft A is supported in fixed bearings (not shown) and is integral with a part C1 of the spider, the other part C of which is supported in ball and roller bearings C3, C4. The annulus G, which may be associated with the torque-measuring apparatus described in Specification 743,418 [Group XIX], is mounted within a ring which is fixed by dowels to the casing D, a splined connection between the annulus and ring allowing a limited radial movement of the annulus. A series of leaf springs are preferably interposed between the annulus and the ring. The outer race of the resiliently-mounted roller bearing K is secured in a ring L, Figs. 2, 3, which is held against rotation relative to the spider-part C1 by a dowel L5 and has four raised portions L3 engaged by resilient bars P. The ends of the bars P contact fingers M1 on a ring M which is secured in a housing N itself held in the part C1 by a ring O. The bars P and portions L3 lie within flanges on the ring L which have projections L4 limiting the radial movement of the bearing 'The two parts C, C1 of the spider are connected by three pillars C5, Fig. 1, and in order to maintain the teeth of the sun H2 in correct mesh in spite of distortion under load, the spider and gearing are conveniently in accordance with the invention of Specification 733,800.

Title: Thermostatic control device
IPC: H01H89/04
Filed: 1974-05-22
Abstract: 1469992 Thermal switches; mechanical switches GENERAL ELECTRIC CO 22 May 1974 [8 June 1973] 22783/74 Heading H1N A thermostat comprises a temperatureresponsive expansible member 38 operating switching means 26, manually-adjustable mechanical biasing means associated with member 38 for selecting the operating temperature, and stepping means in the mechanical biasing means for charging between a temperature range and a single temperature outside that range. Member 38 is a fluid-filled bellows connected through a capillary tube 40 to a remote sensor in an oven; switching means 26 is a double-pole singlethrow normally-closed switch carrying the oven heater current, and is actuated through lever 44 which is a snap action lever supported between adjustment screen 54, the lower end of bellows 38 and insulating bar 48 carrying movable contact blades 28 of switches 26. The manuallyadjustable mechanical biasing means and stepping means comprises a rotary spindle 58 threaded in for axial movement in bush 66 and having an enlarged end portion 56 having an end surface 62 which bears on roller bearings 78 engaging the upper surface of member 38. Rollers 78 are located in a roller retaining plate 80 supported between cover extension 88 and the upper surface of member 38 with an extension 90 guided in a slot in the base, with an adjustment screw 96 bearing on it. During the temperature range (for braking) surface 62 rides on top of rollers, 78, as in Fig. 4 (not shown), which act on member 38, but when a predetermined position is reached (the oven clean position) rollers 78 slip into slots in surface 62, as in Figs. 1, 2 and 3 (not shown), so that the upper surface of member 38 bears against plate 80 thus necessitating greater expansion of member 38 to open switch 26, this greater expansion allowing the oven to reach a higher temperature for heat cleaning before opening switch 26 carrying the current to the oven heaters. This temperature can be calibrated by screw 96. The baking range can be calibrated by holding spindle 58 against rotation and rotating an annular washer 70 supporting bush 66. When spindle 58 reaches the heat clean position, radial finger 76 on spindle end portion 56 depresses slidable cam 104 to depress blade (112), Figs. 3, 4 (not shown) to change over contacts 114, 116, Figs. 3, 4, of an auxiliary switch to signal that the heat clean position is reached. After release, cam 104 is snapped back upwards by spring 118.

[Also in Group VIII] A yarn detector comprises an arm 12 urged against the yarn y by a spring 22 engaging a cranked end 13 of the arm, the end 13 turning and engaging an electrical contact 29 in the event of yarn breakage and thereby completing an electrical circuit to stop the machine. The tension of the spring may be varied by connecting its opposite end to an adjustable lever 25. To avoid stopping the machine in the event of the yarn becoming slack, a clamp in the form of two spring arms 42, 43 is positioned on the holder the yarn being drawn between the ends of the arms and clamped when the arm 12 moves upwardly under the influence of spring 22. Alternatively the clamp may be replaced by a member 45, Fig. 6, which only engages the yarn without clamping it. Instead of the lever 25 for tensioning the spring, a ratchet device operated by turning a knob may be employed.

Abstract: 388,048. Dough-balling &c. machines. POINTON, J. E., HARBER, L. S., Westwood Works, Peterborough, and BAKER PERKINS, Ltd., Hythe Road, Willesden, London. Aug. 12, 1931, No. 22819. [Class 87 (ii).] In a dough-moulding machine comprising a series of rings or cups to which a balling motion is imparted through adjustable crank mechanism axial displacement of the crank shaft is used to effect both the adjustment of the throw of the crank and vertical displacement of the moulding cups. The dough pieces are carried on a conveyer 10 which is driven intermittently by a ratchet and pawl 12 from a cam 13. A crosshead 37 carrying the moulding cups 38 is supported by two crank shafts 18 which are driven by gearing 19 and are displaced vertically by levers 22 actuated by a cam 26. Each shaft 18 carries a crank disc 28 at its upper end which is connected thereto by a key 33 which permits relative axial movement. The crank arm 29 is carried by a pin 30 which is adapted to be rotated by a toothed quadrant which engages sloping teeth 34 on the shaft 18. Thus as the shaft 18 is moved axially the pin 30 is rotated and the distance of the main crank pin 36 from the axis of the shaft 18 is varied. Continued upward movement of the shaft 18 causes it to engage the crank disc 28 and raise the cups 38 clear of the dough pieces. The adjustable crank mechanism may be applied to other machines than dough-moulding machines. Specification 387,716 is referred to.
