Title: Improvements relating to differential speed measurement
Inventor: BARANY THOMAS ERNEST
IPC: G01P3/56
Filed: 1956-10-25
Abstract: 829,204. Speed measuring devices. BRITISH THOMSON-HOUSTON CO. Ltd. Oct. 16, 1957 [Oct. 25, 1956], No. 32582/56. Class 40 (1). The difference between the speeds of two members rotating at speeds approximating to a nominal value is measured in a circuit of a tachogenerator driven by a differential device which is coupled to the two rotating members, a compensating signal being also introduced into the measuring circuit which varies in accordance with the nominal speed value and is selectively adjustable in magnitude and sense in accordance with the compensation required at any particular speed value. In the Figure, the selsyn transmitters 4 are driven by successive rolls in a paper machine driven at the nominal speed by the motor 3. Differential selsyns 5 receive inputs from adjacent transmitters and drive tachogenerators 6 to give outputs on the voltmeters 8 representing the differences in speed of successive rolls. A further tachogenerator 11 is driven by the motor 3 to give an output proportional to the nominal speed, and from this output is obtained a signal adjustable in magnitude and sense by the potentiometers 12, 14. The speeds of the individual motors driving the selsyns 4 are initially set up so that the peripheral speeds of the various rolls are correct for the amount of draw to which the paper is to be subjected, and any deviation from these conditions is detected by observing the readings of the voltmeters.

Title: Improvements in and relating to brake mechanism
IPC: B60T11/04
Filed: 1929-10-29
Abstract: 346,015. Brake transmitting mechanism. ROCKWELL, E. A. and EVANS, E. R., 1725, Diversey Parkway, Chicago, U.S.A. Oct. 29, 1929, No. 32813. Convention date, May 29. [Class 103 (i).] A brake mechanism comprises a power operating arm 12 arranged to actuate an intermediate lever 30 which exerts a thrust on a lateral contact face provided on a brake applying lever 17. the contact face being in a plane at right-angles to the plane of movement of the brake applying lever. The power is derived from the vehicle transmission shaft. The levers 30, 17 are independently rotatable on a common pivot 18. The lever 30 is provided with an arm 37 which engages an arm 38 on the lever 17 in order to turn this lever. The front brake connection 15 is attached to the lower arm of the lever 17 at a point further from the pivot 18 than the connection 16 to the rear brakes in order to obtain greater power exerted on the front brakes. The bearing opening in the lever 17 may be elongated horizontally in order to equalize the pull on the front and rear brakes. An emergency brake lever 21 is connected by a rod 25 to the pivot 20 connecting lever 17 and rod 15.

Patent GB-389775-A (GB)
Title: Improvements in or relating to servo operating mechanism for change speed gearing
IPC: F16H61/02
Filed: 1932-11-21
Abstract: 389,775. Controlling changespeed gearing. EDGE, S. H. and CLAYTON DEWANDRE CO., Ltd., Titanic Works, Lincoln. Nov. 21, 1932, No. 32882. [Class 80 (ii).] In gear changing upon a vehicle in which the change is effected in a gearbox 1, Fig. 1, by depressing a pedal &c. 3 after preselection by suitable means (not shown), the manual effort on the pedal is assisted by a pneumatic relay 7 when the resistance to the operation of change-effecting lever 2 exceeds a limit. In the form shown, the levers 3, 2 are connected by links 12, 4 and a lever 9, and the link 12 is adapted to yield or stretch so as to open a valve to connect the relay cylinder 7 to engine suction in a duct 15. The relay acts on the lever 9 at 8. The yielding or lost-motion takes place within a valve casing 11 jointed to the lever 9 and into which the link 12 projects. Tension of the link 12 is passed on to the lever 9 through a spring 25, Fig. 2, which yields when the stress is more than the driver can conveniently exert. The suction port 15 leads to an annular recess 16 normally cut off by a sleeve valve 17 held by a light spring 27. In the unstressed position shown, a port 19 leading to the servo cylinder 7 is connected through a chamber 20 and through the hollow of the sleeve 17 to vents 29 opening to the atmosphere. On manual effort being applied, sufficient to compress the spring 25, a valve element 23 on the link 12 first closes the end of the sleeve 17 and then moves the sleeve 17 to the left, thereby closing the vents 29 and opening the recess 16 to the chamber 20. Suction then operates in the cylinder 7 to assist the manual effort still applied to the lever 9. Instead of the suction cylinder 7, a bellows operated by compressed air might be used.

Nov. 30, 1931, Nos. 33068/31 and 12425/32. [Class 112.] Laterally vibrating needle carriers are guided by a cam slot 32 so that the lower dead centre position of the vertical oscillation is such that the needle loop will meet the rotary hook 5. A needle carrier 28, which is mounted to slide vertically in a guide 26, carries a pin 30 which projects through an aperture 31 in the guide 26 and engages a cam slot 32 in a horizontal guide 24. The guide 26 is reciprocated laterally by the link mechanism 40, 33, 4, and the horizontal guide 24 is reciprocated vertically by the needle bar 3. A wide throw is imparted to the needle by a multiplying linkage 33, 40, 44. The device may be employed with two needles. Thread-tension devices which decrease the tension as the throw is increased comprise two conical members 56 which are pressed together by a spring 57. The same movement of the lever 9 which varies the throw of the needle, varies the spring tension by means of the link mechanism 55, 53, 46, 47, 11a, 11, 12, 13, 22.

Title: Improvements in the manufacture of films, foils, and the like and apparatus for use in such manufacture
IPC: B29C48/08
Filed: 1936-12-04
Abstract: <PICT:0486769/IV/1> <PICT:0486769/IV/2> <PICT:0486769/IV/3> Films, foils, and like products are obtained by evaporating a volatile solvent from a layer of film-forming dope on a travelling support and a colouring-agent or other desired constituent of the product is introduced into the partly dried layer of dope by causing a solution of said constituent to flow, drip, or be sprayed on to the surface of said layer from supplying means kept out of contact with the surface. Coloured foils of cellulose acetate are produced by extruding the acetate solution in acetone on to an endless nickel band passing through a warm atmosphere and causing to flow on to the surface of the foil just beyond the point of extrusion a solution of a dye in acetone, or alcohol, and containing a plasticizer such as dimethyl phthalate.  The dye may be methylene blue, malachite green, 1-4 di(methylamino) anthraquinone, or 4-nitro-2-methoxy benzene azo dimethyl aniline. The device for applying colouring or other liquid may comprise a reservoir for the liquid with adjustable aperture, a wick or curtain of porous material for causing flow of liquid from the reservoir to the surface of the film, the wick extending downwardly through the aperture, means for varying the aperture to control the amount of liquid passing through the wick, and means for micrometrically adjusting the height of the lower edge of the curtain above the surface of the film.  As shown in Fig. 1, the endless band 10 passes the extrusion device 13 from which film-forming solution is extruded on to the band.  It then passes the liquid-applying device 14.  As shown in Figs. 2 and 4, the liquid applying device is of V-shaped section and has a fixed side 15 and fixed ends carried by brackets 17 and micrometer screws 18 resting on fixed brackets 19. The other side 26 of the trough is pivotally mounted on a bolt 27. An extension 28 of the side 26 functions as a crank to move the side about its pivot 27 so varying the side of the aperture between the sides of the trough. The adjustment of the aperture is made by turning the head 35 of the micrometer screw 31.  A curtain 37 comprising a foraminous base wound with layers of flannel extends from the trough downwardly towards the film-forming band.  In operation the curtain is first brought into contact with the freshly extruded layer of film 41 and the screws 18 are then altered so as to bring the curtain itself but not the stream of liquid oozing therefrom out of contact with the film.  The wick may extend across the whole surface of the band for uniform colouring.  Local colouring may be effected and two or more liquid applying devices in line or staggered relationship may be provided.  Other liquid applying devices may be used and the liquid may be sprayed or dripped.  The feed to the liquid-applying device may be by gravity or pump. Instead of colouring matters, plasticizers and non-inflammators may be applied to films in the same manner.
