Title: Methods of and apparatus for winding coils
IPC: H01F41/06
Filed: 1963-07-18
Abstract: In a method of winding a multiple layer tapped electrical inductor coil (see Division H1) wire 26 (Figs. 7 and 9, not shown) is fed by traversing guide 30 to a rotating spool 20 and when a predetermined number of turns have been wound on the spool, rotation of the spool is lowed and then stopped, the guide 30 being moved to an end position adjacent terminal strips 24 carrying a number of L-shaped terminal posts 25.  The guide 30 is next indexed in the transverse direction to any desired predetermined terminal peg 25b and rotated thereabout to provide a tapping for the coil.  The guide 30 may then be returned to the normal traversing position and winding on the spool continued or alternatively the guide may first be indexed to a further terminal peg, rotated about it, and then returned to the normal spool winding and traversing position.  In a machine (Fig. 1, not shown) for winding a number of identical spools 20 mounted at accurately spaced intervals by means of spacer members on a spindle 31 the spools are fed with wire by an equal number of wire guides 30 which are rigidly mounted on a frame 42.  The latter reciprocates during the spool winding step on a traversing shaft 43 under the action of a rotary face-cam 53 which is retracted by an air cylinder 65 when the desired number of turns has been wound.  The frame 42 with wire guides 30 then moves to the spool-end position under the action of spring 52 against a stop 69.  Transverse movement of the frame 42 to bring the guides 30 adjacent the desired terminal posts on the spool flanges can be effected by reason of the fact that the support 45 on which the shaft 43 and frame 42 are mounted is slidable in the transverse direction on a base plate 46.  The transverse movement is effected by an indexing cam 80 (Figs. 2 and 4, not shown) the profile of which determines the extent of this movement and therefore selects the terminal about which the tapping connection is to be made.  Base plate 46 is mounted on four pillars 91 having universal coupling connections to the plate so that it may be gyrated by eccentric cams 100 thus causing all the wire guides 30 to rotate about the terminal pegs selected for the tapping.  Electronic counting means are provided to count the revolutions of the spindle 31 and to control the speed of a high and low-speed driving motor 34 in order that rotation of the spools should be arrested accurately after the required number of turns has been wound and stop means 111, 112, 116, 117 (Fig. 3, not shown) are provided to ensure that the spool is arrested with the terminal pegs in a vertical position. Means are also provided to orientate the face cam 53 after retraction so that when returned to the operating position i.e. for resumption of winding on the spool, the guides 30 commence operation from the end position adjacent the spool flange bearing the terminal pegs.

Title: Improvements relating to organopolysiloxanes containing silicas as fillers
Filed: 1955-10-06
Abstract: Silicas are rendered hydrophobic by reacting them with alkanols such as methyl, propyl, butyl, amyl, hexyl, heptyl, octyl, nonyl, decyl and octadecyl alcohols.  In Example (2) a silica aerogel having a surface area of 100 to 200 square metres per gram was wetted with alcoholic potash and heated to 375 DEG  C. in a closed bomb; excess alcohol was then vented and allowed to escape, while the reaction product was cooled for 2 hours in an atmosphere of alcohol vapour, to give a freeflowing powder which floated on the surface when stirred into boiling water.ALSO:An elastomer-forming composition comprises an organopolysiloxane convertible to the cured, solid, elastic state and as filler a finely-divided silica which has been rendered hydrophobic by reaction with an alkanol.  The convertible siloxanes used are well-known and are described e.g. in Specifications 594,481, [Group IV], 618,453 and 640,067 and may contain the customary hydrocarbon radicals and halogenated hydrocarbon radicals such as chlorophenyl and dibromophenyl.  The hydrophobic silicas, preferably having a surface area of from 1 to 900 square metres per gram, may be made by the process of Specification 27751/55, which describes the preparation of ethanol modified silicas, by using, e.g. methyl, propyl, butyl, amyl, hexyl, heptyl, octyl, nonyl, decyl and octadecyl alcohols (see Group III).  The hydrophobic silica may be used in amount of up to 100 parts by weight per 100 parts of siloxane, and the resulting mixture may be cured at 100 DEG  to 200 DEG  C. in the presence or absence of organic peroxides, e.g. benzoyl peroxide and t-butyl perbenzoate.  Conventional fillers, e.g. zinc oxide, titania, alumina, iron oxide and asbestos, may also be added.  In Example (3) a convertible methylpolysiloxane is milled with various amounts of hydrophobic silica and press cured.

Abstract: 1,179,459. Sample-injection apparatus for gas chromatography. BODENSEEWERK PERKIN-ELMER & CO. G.m.b.H. 21 June, 1967 [24 June, 1966], No. 28707/67. Heading B1L. Sample injection apparatus for use with a gas chromatographic column comprises a conduit, including a valve, extending from a carrier gas source to the inlet connection of the column and a second conduit for the sample extending from the inlet to a cannula for insertion through a self-sealing diaphragm on a sample container. In use, the cannula is inserted through the diaphragm with the carrier gas flowing through it so that a pressure is built up in the sample container. The valve is then closed and sample is forced up the cannula into the column. The valve is then opened and the flow of sample is interrupted and the cannula withdrawn. The continued flow of gas through the cannula ensures that it is swept clean for the next sample. To lessen the loss of carrier gas, a changeover cock may be used to connect the inlet to atmosphere via a throttle and the cannula direct to the carrier gas conduit via a throttle. Alternatively, as shown in Fig. 5, the cannula 50 may be carried by piston 52 about which is fitted a cylinder 54, the interior of which communicates with the atmosphere through a throttle tube 72. To inject a sample, the sample container 20 is raised to push the cylinder 54 upwardly against the action of a spring 70 so that the cannula 50 pierces a self-sealing diaphragm 60 at the end of the cylinder and the self-sealing diaphragm 22 on the sample container.

Abstract: 443,605. Dispensing aerated liquids. JOFEH, E. J., 12, York Street, Portman Square, TRILLING, J. G., 3, Nutley Terrace, Hampstead, and WALSH, S. J., 154, Mill Lane, West End, all in London. Oct. 10, 1934, Nos. 29007 /34 and 11569 /35. [Class 116] Aerated liquids, particularly lager and other highly carbonated beers and stout, are dispensed by supplying the liquid to a glass container 1 by way of a pipe 7 in constant communication with the container, and then drawing off the liquid by means of a multiposition plug valve 10 which first vents the container 1 and then allows the liquid to flow therefrom. If desired, the flow may be accelerated by moving the plug valve to admit gas under pressure to the container, and, by cutting off the dispensing operation, this gas pressure may be used to return the liquid in the container to a storage cask &c. The plug valve-box consists of a casting having a central passage 9, Fig. 2, communicating with a bore 8 in the base plate 3 of the container, a passage 16 communicating with a vent pipe 14 and a passage 15 through which gas may be supplied to the container. A passage 17 below the passage 15 communicates with a supply of carbon dioxide or other gas under pressure and spring-loaded valves such as 18 are fitted in the passage 17 and in the vent passage 16. The plug valve, Fig. 5, has a port 29 communicating with the discharge orifice 10, a vent 30 communicating directly with the atmosphere, and ports 26, 27, 28 adapted to register with ports in the passages 15, 16 and 17. The plug valve takes up five different positions, effecting operations as follows : (1) all passages closed ; (2) interior of container connected to atmosphere through spring-loaded relief valve in passage 16 ; (3) the vent opened in operation (2) remains open and liquid is allowed to flow from container through discharge orifice 10 ; (4) the vent and liquid discharge orifices remain open, while gas under pressure is admitted to the container to accelerate flow ; (5) the vent and liquid discharge orifices are closed, but the gas pressure continues to be applied to the container, thus returning all liquid from the container to the liquid supply line. A plug valve 31 in the pipe 7 couples the container 1 either with the beverage supply 32 or with a pipe 33 through which cleaning fluid may be supplied.

Title: Improvements in and relating to position-control systems
Inventor: WEST JOHN CLIFFORD
IPC: G05D3/14
Filed: 1951-12-11
Abstract: 754,105. Electric follow-up systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 11, 1953 [Dec. 11, 1951], No. 29011/51. Class 40(1) [Also in Group XL(c)] In a position control system having a controlled element supplying a signal representing its instantaneous position to a mixing circuit to which is also fed a signal representing its required position the output of the mixer circuit which is a signal proportional to square root of error magnitude and of the same sign as the error, is applied together with a signal proportional to velocity of the element, to a high gain amplifier controlling the element, e.g. through a servomotor. The amplifier is saturated by low input signals and the servomotor therefore runs under full forward torque until the amplifier input becomes zero at a position midway between the initial and required positions of the element, when full reverse torque is applied to bring it to rest. The signal proportional to velocity is obtained from a tachometer generator or an equivalent signal proportional to the first derivative of error signal is produced by the anode follower circuit of Fig. 5. The square root signal is generated from the error signal in the circuit of Fig. 6 in which valves V1 1  and V1 2  are worked on non-linear parts of their characteristics to produce outputs proportional to the square roots of negative inputs while having positive input signals short circuited by diodes 6 and 7 respectively. V1 1 , fed directly with the error signal therefore gives an output only for negative error signals, while V1 2  which is fed through inverter V2 gives an output only for positive errors, which is inverted by V3 so that the input to mixer V4 changes in sign with the error. The output of V4 is inverted by V5 and amplified in variable gain amplifier V6, the output of which, together with the velocity dependent signal is fed to the servomotor controlling amplifier which saturates at low inputs. The invention may be used in the system described in Specification 750,294 in which the movable element carries a pick-up member close to a series of insulated segments to which are applied pulse signals intercollated in time. Because of capacity between the pick-up and segments a signal representing position is derived, which with signal predicting a desired position is fed to a circuit as shown in Fig. 6, the output of which is fed with a first derivative of error signal to a saturable amplifier supplying current to a coil on the element moving in a magnetic field. In this system the square root signal may be obtained by suitable shaping of the pickup member. Specification 687,520 [Group XXII] also is referred to.
