Abstract: 703,513. Ships' propellers. ENGLESSON, J. E. Dec. 17, 1951 [Dec. 27, 1950], No. 29504/51. Class 114 [Also in Group XXV] Screwed joints, in the hubs of ships' propellers having adjustable blades and in which at least one member of the joint is made of stainless steel, have the threads and other sliding bearing surfaces given a thin coating of metal having better sliding properties, such as copper or silver, or alloys consisting mainly of these, in order to prevent seizing. When copper is used the coating may be applied electrolytically and should not exceed 0.1 mm. in thickness 0.01 mm. being a preferable value. Where the joints are exposed to salt water they are sealed to prevent the water from contacting the coated surfaces. The sealing may be effected by coating the joint with thick oil, pitch, putty, red lead, or oil paint.

Filed: 1968-06-25
Abstract: 1275061 Boring heads STUART DAVIS MACHINES Ltd 25 June 1969 [25 June 1968] 30156/68 Heading B3C A rotatable tool head, e.g. a boring head, comprises a stiff diaphragm 25, a cutting tool holder 27 secured to a face of the diaphragm and means for applying a force to the diaphragm to distort the face to tilt the holder and thus adjust the position of a tool when held in the holder. In one embodiment (Fig. 1) an axially movable actuator 13 carries a part 17 having a tip 20 which bears on a lever 21 engaging a stud 26 at the centre of the diaphragm, which centre is eccentric relative to the axis of the head. Axial movement of the actuator 13, to the left in the Figure, thus causes the diaphragm to assume a conical form. The holder 27 is secured to the front face of the diaphragm only on one side of a diameter of the diaphragm, thus leaving a slit 28 between that face and the holder, whereby distortion of the diaphragm causes the holder axis to assume an inclination relative to the axis of the head, thereby adjusting the disposition of a tool 16 relative to the head. A precompressed spring 32 prevents backlash between the lever 21 and part 17. In another embodiment (Fig. 3), the tip 20 bears on a first lever 36 which transmits force to a second lever 21 through a projection 37 on the latter. In another embodiment (Fig. 5), a closed cavity between the diaphragm and a rear plate 12 of the head is filled with a suitable hydraulic liquid. Axial movement of a member 42 under the action of actuator 13 causes force to be transmitted by the liquid to the diaphragm. In a modification of the Fig. 3 embodiment, levers 21, 36 have intermeshing gear teeth. The head may be a facing head. Copending Application No. 30155/68 is referred to.

Receiving apparatus, Figs. 2, 3.-The mixer 8, Fig. 2, comprises a low-Q cavity, Fig. 3, formed by an outer conducting shell 25, and an inner conductor 26 is connected to a diode 27. Screw 28 permits adjustment of the cavity to the transmitter frequency. All A.C. components except the beat frequency are by-passed to earth by capacitor 20, Fig. 2, the D.C. component being passed via amplifier 13, voltage comparator 14 and OR gate 62 to the alarm circuits 63 . . . 65, thereby monitoring the system. To define the boundaries of the system the B.P. amplifier has sharp upper and lower cut-offs, and comprises stages 30 . . . 33 with the upper B.P. limit controlled by capacitors 36 and 40, and the lower limit controlled by capacitors 15, 38 and 48. The B.P. amplifier output is fed to a D.C. restorer and integrator circuit 46 which inhibits response to incoherent signals, e.g. noise and signals from small animals, weeds &c. Zener diode 52 ensures constancy of D.C. level at the junction of capacitor 48 and diode 50. The output of circuit 46, if sufficient, actuates a Schmitt-like trigger circuit 56 the triggering level of which is set by resistor 60. The trigger circuit output actuates an alarm bell or light 65 via OR gate 62. Protected areas, Fig. 6.-The protected area may be a room, Fig. 8 (not shown).

Filed: 1955-10-24
Abstract: In a process for the manufacture of polyethylene glycol terephthalate, a preliminary condensate of low molecular weight and having an intrinsic viscosity up to 0.3, prepared from dimethyl terephthalate and ethylene glycol is completely condensed by heating it for a short time to temperatures ranging from 310 DEG  to 350 DEG C., preferably from 315 DEG  to 335 DEG  C. under a reduced pressure of between about 1 and about 0.05 mm. mercury with agitation of the fused mass until a polyethylene glycol terephthalate is obtained which is capable of being spun.  When the condensation has been terminated the fused mass is advantageously cooled to 270 DEG  to 280 DEG  C. before being discharged. The preliminary condensate may be prepared by reacting 1 mol. of dimethyl terephthalate with 2.2 to 2.5 mols. of glycol.  The process may also be applied to a mixture of the preliminary condensate prepared from terephthalic acid and glycol with admixtures of other dicarboxylic acids and/or glycols.  When the process is effected continuously a molten preliminary condensate may be heated to 270 DEG  C. at reduced pressure, then passed through a closed channel at the reaction temperature and then after cooling again to 270 DEG  to 280 DEG  C. the mass can be cooled with water or be spun directly.  Specification 578,079, [Group IV], is referred to.
