Filed: 1961-09-19
Abstract: 922,052. Timepiece gauging apparatus. M. SCHMIDT. Sept. 19, 1961, No. 33473/61. Class 139. A mainspring and bridle torque gauge A, Fig. 1, is used with a lathe B to test the mainspring and bridle within a barrel E the arbor 10 of which is secured by a clamp 15 to the lathe spindle C. The gauge A includes a balancing spring 28, Fig. 3, connected to a spindle 26 having at one end a pointer 27 and, at the other end, a pinion 25 meshing with opposed crown gears 23, 24 freely rotatable on a shaft 20. Between the gears 23, 24 the shaft 20 carries a finger member 40 which, in accordance with the direction of rotation of the shaft, abuts one or other of two finger members 42, 41 extending from the gears 23, 24 respectively. The pointer 27 has a pin and slot connection with a maximum position pointer 39. A pin 17, Fig. 1, extends from the clamp 15 to abut a pin 18 extending from a crank arm 19 carried by the shaft 20. If the mainspring and bridle assembly is wound by rotating the lathe spindle C, the spring 28 of the gauge is stressed via the shaft 20, gear 23 or 24, pinion 25 and shaft 26. The operator senses the instant at which the bridle becomes effective and reverses the rotation of the lathe spindle C. The torsion of the bridle spring is indicated by the pointer 39 and the torsion of the mainspring by the pointer 27. The springs are matched if the pointers do not diverge by more than an amount defined by an extension 44 of the pointer 27.

Title: Improvements relating to the extraction of castor oil
IPC: C11B1/10
Filed: 1946-11-12
Abstract: In the production of castor oil by solvent extraction, a miscella of castor oil and an aliphatic hydrocarbon solvent is formed and maintained above the critical minimum miscibility temperature for the components of the miscella, the miscella is then cooled below this temperature, at which the miscella becomes turbid, to separate into an oil-rich phase and an oil-poor phase, the oil-rich phase being withdrawn.  The solvents generally comprise liquid aliphatic hydrocarbons of B.Ps. of 60-250 DEG  C., preferably one or more aliphatic hydrocarbons of 6 to 8 carbon atoms, i.e. hexane, heptane, octane, their isomers and mixtures principally thereof.  The process ensures the minimum volatilization of solvent from the oil-rich phase to recover the castor oil compared with the usual volatilization of all of the solvent in the typical leachings with solvents such as benzine. The process may be applied to castor beans, castor bean pomace or preferably to a castor bean pulp produced in a mill from the castor bean kernels and a proportion of the miscella from the extraction system.  The process may be carried out in conjunction with the extraction method of Specification 632,304, comprising an over-all counter-current process composed of repeated concurrent stages, but any batch or continuous extraction system may be used. The solvent recovered from the oil-rich phase may be recycled to the process; the oil-poor phase may be re-cycled without separation.

Title: Improvements in manipulating devices for liquid measuring instruments
IPC: B67D7/16
Filed: 1932-12-01
Abstract: 411,134. Fluid - actuated valves. WILSON, H. J. Branscombe, Highweek, Newton Abbot, Devon. Dec. 1, 1932, No. 33960. [Class 135.] Valves controlled by pilot or relay valves.-In liquid dispensing apparatus of the type fitted with a three-way valve by means of which a measuring container may be placed under vacuum when it is to be charged with a measured quantity of liquid and under atmospheric pressure when the liquid is to be discharged, the three-way valve is adapted to be operated manually to connect the measuring container to vacuum and automatically by pneumatic means to connect the container to atmosphere when the desired amount of liquid has been introduced. A measuring container Y is provided with an adjustable inlet and overflow pipe Z and may be connected to atmosphere or vacuum by a rotary three-way valve the operating lever of which is shown at e. The valve operates in a pipe a connected to the container and to vacuum. A piston rod g passes freely through the lever e and is provided at the upper end with a stop by which the lever may be moved downwardly to connect the container to atmosphere. The lower end of the rod g carries a piston operating in a dashpot cylinder h the bottom of which is adapted to be connected with the pipe a through a valve t operable by a lever W. In operation, assuming the lever e to be in its upper position, the container is connected to vacuum and liquid is drawn in through the pipe Z. When the level reaches the top of the pipe Z, the rising of a float g<1> operates a trigger d<1> through a cable f which trigger in turn operates the valve t and connects the underside of the piston to vacuum. The lever e is thus moved downwardly and the container connected to atmosphere. Meanwhile the underside of the piston is also connected to atmosphere and the piston returns to the upper position under the influence of a spring (not shown), the lever e remaining in the lower position. On the opening of the outlet cock of the container the float descends and the valve t closes. The container may then be recharged by a manual operation of the lever e. In order to vary the relative positions of the valve t and trigger d<1>, for the measurement of different quantities of liquid, the valve mechanism is slidably mounted on a rod c<1> along which it is moved by an endless cable b<1> attached to and moved by a projection a<1> on the adjustable inlet pipe Z.

Title: Improvements in or relating to roll film photographic cameras
IPC: G03B19/04
Filed: 1947-12-29
Abstract: 638,660. Photographic roll-film cameras. KODAK, Ltd. Dec. 29, 1947, No. 34510. Convention date, Jan. 8. [Class 98 (i)] A camera includes a receptacle into which is axially loadable for exposure a roll film cartridge comprising a flanged spool carrying the film and enclosed in an open - ended cylindrical container, means which limit the axial movement of said container into the receptacle but permits the spool to continue its axial movement to a film-advancing position independently of the container which may then be removed, the receptacle including a snap-latch which cooperates with a flange of the spool to retain it in loaded position. As shown, the film car- . tridge comprises a spool 5 with dished end flanges 2, 3, which retain on the spool in substantially light-tight manner a film having an opaque back, and an open-ended cylindrical container 7 having an annular internal flange at the upper end against which the flange 2 is pressed, and dimple catches which snap beneath the rim of the lower flange 3 so that the spool is held in light manner in the container. The cartridge is loaded endwise into a supply spool chamber which is provided with an external hinged door and in which is disposed a cylindrical holder 33 having a cutaway portion 38 and carried by a support 34 secured to the bottom wall 135 of the camera. The holder 33 is formed at diametrically opposite positions with spring arms 40, 45, each having an inwardly bent finger as 42 and an inwardly projecting lug as 43, the arm 40 being disposed at one edge 39 of the portion 38 while another similar spring arm 49 having an inwardly projecting finger 48 and a manually operable extension 51 is disposed at the other edge of the portion 38. On loading the cartridge into the holder, the cartridge moves down to the position shown when the fingers of the arms 40, 45 engage the bottom 8 of the container 7. By pressing on the upper spool flange and pulling on the container, the snap latch 8, 10 is released and the spool moves downwardly out of the container, pressing the arms 40, 45 outwardly and is latched in the holder by the finger 48 of the arm 49 engaging above the rim of the lower flange 3. The container 7 is then freely withdrawn and the spool chamber door closed. On rotating the film winding knob (Fig. 2, not shown) on a shaft 83 which extends into and engages the spool core, the tapered tongue of the coiled film is engaged between a guide plate and a waisted roller as described and claimed in Specification 558,515 so that the film is curved across its width, allowing it to pass off the spool between the dished flanges, and is wound across the exposure aperture into an empty chamber from which it is completely re-wound when all the exposures have been made. To remove the exposed spooled film the container 7 is placed over the spool disengaging the latch 48 and the latch 8, 10 pressed home so that the cartridge may then be withdrawn as a light-tight unit.
