Filed: 1924-12-30
Abstract: 233,299. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. May 5, 1924, [Convention date]. Aspirating-apparatus, ejector.-In a mercury vapour air exhausting apparatus having several stages, one or more of such stages being formed by an annular jet tube, the stream of metal vapour through the annular jet tube or tubes is determined by a partition in which several apertures are provided. A vessel 1 contains mercury 15 which, on being vaporized, flows through a metal tube 2 surrounded by an insulating jacket 3 to a downwardly-bent portion 4 whence part passes through a number of apertures 6 and part through a conical hole 16 in a nozzle 5. The vapour that has passed through the apertures 6 flows through an annular jet tube formed by a cylindrical wall 17 on legs 20 and the outer wall of the nozzle 5. After leaving the outlet 18 of the annular jet and the outlet 19 of the nozzle 5 the vapour condenses on the wall of a vessel 7 which has a constriction 8 and is cooled by a cooling liquid that flows through a vessel 9 having an inlet 10 and a discharge 11. A high vacuum conduit 12 and a low vacuum conduit 13 communicates with the vessel 7 at the upper and the lower ends of the vessel 7 respectively. The condensed mercury passes through a pipe 14 back to the vessel 1. The ejector may be arranged in series with a low vacuum pump or with another similar ejector. Metal such as lead, tin, bismuth, cadmium or zinc may be used instead of mercury.

In the construction shown, the rock shaft is secured by a screw 8 in a slot formed in the upper end of the member 7. The member 9 is provided with a screw-threaded rod 11 the lower end of which has a slidable plunger 14 spring-pressed against the upper end of the carrier 10. A rotatably-mounted nut 12 engaging the rod 11 is adapted to adjust the pressure of the spring 13. The lower end of the carrier 10 has pivotally-mounted thereon the holder for the wiper, so that the spring 13 acts to press the wiper against the wind screen. The movement of the wiper towards the screen is limited by means of a stop screw 15. A catch plate 16 pivotally mounted on the member 7 normally maintains the member 9 in position suitable for operation of the wiper, but may be swung aside to permit withdrawal of the member 9 and wiper away from the screen.

Abstract: 2,2,5,5 - Tetramethyl - 2,5 - disila - 1,3 - dioxolan of the formula <FORM:1080397/C3/1> may be prepared by two methods.  One method comprises heating a mixture of equimolar amounts of 1,3 - di - (hydroxymethyl) - tetramethyldisiloxane and 1,3 - di(bromomethyl)-tetramethyl disiloxane and excess methylamine until salt precipitation is complete, removing the nitrogen compounds from the mixture, adding p-toluene sulphonic acid as catalyst, distilling under reduced pressure and recovering the product as the distilate. The second method comprises heating a mixture of equimolar amounts of dimethyl - (acetoxymethyl)-acetoxysilane and dimethyldiethoxysilane, 5-20 fold molar amount of methanol and p-toluene sulphonic acid as catalyst, distilling off methanol, ethanol and methyl acetate, and then distilling under reduced pressure and recovering the product as the distillate.  Hydrolysis of the product alone gives 1,7-di-(hydroxymethyl)-octamethyltetrasiloxane and cohydrolysis with organoalkoxysilanes gives organopolysiloxanes with terminal hydroxymethyl groups.  Copolymerization with trioxan gives polyoxymethylenes with siloxane segments.

Conical reflectors 32, 35 have sides at angles of 3 degrees to horizontal, and are spaced apart such that the apices of the cones do not coincide in order to meet latest regulations. Current supply conductors 17 for lamp bulb 37 pass through spacing sleeves 20. Lamp bulb 24 providing the all-round white light may be used for morse signalling and warning only, and may accordingly be supplemented by an anchor light provided by a low consumption high intensity bulb mounted in annulus 26 (Fig. 4, not shown).

Abstract: 906,713. Slip measurement for Koepe pulley. ENGLISH ELECTRIC CO. Ltd. Oct. 3, 1958 [Oct. 8, 1957], No. 31494/57. Class 78 (5). The slip between mine cable 13 and the Koepe driving pulley 10 is measured by meter 26 from the output of magnetic amplifier 23. A signal proportional to the speed of pulley 10 is generated by tacho-generator 19 driven by the pulley driving-motor 12, is rectified at 22, and fed through coil 23a to amplifier 23. Similarly, a signal proportional to the speed of cable 13 is generated by induction tacho-generator 20 of the kind described in Specification 906,712, is rectified at 24 and fed through coil 23b to said amplifier, in a sense to oppose the other signal. The output signal of the amplifier is therefore proportional to the difference of the two speeds and meter 26 summates these output signals to indicate the accumulated net slip of the cable over any required period of time.

Title: Serial coder
Inventor: TEESDALE REGINALD ROY
IPC: H03M1/00
Filed: 1966-07-15
Abstract: 1,101,599. Analogue - digital converters. STANDARD TELEPHONES & CABLES Ltd. 15 July, 1966, No. 31892/66. Heading G4H. In an analogue to digital converter of the type in which an unknown input signal voltage after sampling is compared with reference voltages which are modified until a balance is obtained, to prevent errors which might be introduced by the decay of the sampled voltage during a comparison process, the fixed reference voltages are multiplied by a time varying function chosen so that the sampled voltage and the reference voltages decay at the same rate. In the embodiment described the sampling circuit consists of an emitter follower 10 feeding, via a gate 11 enabled by sampling pulses, a capacitor 9 shunted by a resistance 12 which determines the time constant of the decay of the sampled voltage. After amplification the signal is applied to a subtracter 5 (Fig. 1) where the voltage from a decoder 4 is subtracted from it and the difference signal fed to a comparator 6 which determines whether the voltage exceeds half a quantum. A logic unit 7 controls weight generators 2 in accordance with the output of the comparator circuit 6 and also supplies a serially coded output. The weight generators 2 all provide equal currents when a sampling pulse is capacitatively coupled to the bases of transistors 15 (Fig. 4). This pulse causes the transistors to switch on and produce currents via gates 3 enabled by the logic unit to the resistor attenuator network of the decoder 4. A resistance 19 shunting the base of transistor 15 has a value chosen in conjunction with that of capacitor 14 to give a time constant equal to the decay of a sample voltage in the sample and hold circuit.
