Title: Improved variable electric condenser
IPC: H01G5/06
Filed: 1926-12-29
Abstract: 286,816. Johnston, F. R. Dec. 29, 1926. Condensers of the kind wherein two or more plates or sets of plates are geared together so that movement of one plate or set of plates causes proportional movement in the same direction of the other plate or set of plates, but at a different speed, have the plates mounted coaxially. The one set may be operated by a knob either directly or through reduction gearing. The principle is illustrated in Fig. 1, wherein the plate or set of plates a is arranged to move from x to x<1> about the pivot c, whereas the other plate or set b moves from y to y<1>, a slightly larger distance, and so provides a small change in capacity. The invention is applicable to fine adjustment condensers in combination with those of ordinary construction, as well as in combination with a fixed condenser. Further, there mav be employed additionally a set of plates rotating in the opposite direction to provide a coarse adjustment, and the plates may be designed for a straightline frequency relation. There may also be used moving dielectric (mica) plates, and they may be used as a pair, after the manner of the metal plates, or one movable dielectric plate may be used with a movable metal plate and a fixed metal plate. Many forms are described and illustrated in detail, and Fig. 2 shows a typical example wherein one set of plates a on a shaft d is rotatable from the knob through pulleys g, h, m, n, shafts k, o, and chains or cords l, p, whereas the vanes b are rotated directly by means of their support t. In another form employing two metal plates, one is adjustable to or away from the other to vary the dielectric thickness and maximum capacity. A form suitable for use with a liquid dielectric is also described and shown, and employs only two metal plates. In another form interleaving semicylindrical plates are used. In Fig. 15, cylindrical fixed plates 104, 105 are separated by two part-cylindrical dielectric plates 106, 107 rotatable about a common axis 110, but the dielectric or condenser plates may also be moved axially. In Fig. 12, one plate 76 in addition to being rotatable together with its supporting arm 74 about the common axis 73 is also independently rotatable about the point 77.

Abstract: 1,270,785. Knitting; looms. FOUQUETWERK FRAUZ & PLANCK. 8 July, 1970 [28 Jan., 1970], No. 33032/70. Headings D1C and DIE. A thread supply device for a shuttleless loom or knitting machine comprises a stationary helically grooved cylinder 2 and a rotatable two pronged fork 6-8 which winds thread, supplied via eye 17, onto the cylinder. Yarn is removed via an eye 18 adjustable relative to the cylinder. The device functions as a positive feed with yarn passing through guide in position 18', preferably however the guide 18 is positioned axially of the device which functions as a store. In a variant the eye is adjustable vertically of the cylinder. Accumulating turns of thread move down the thread but are frictionally retarded where they pass over the prongs. The resultant axial movement of the prongs and axle 12 against spring 9 disengages clutch 11, 13 in its drive. The fork may be driven by an individual motor housed in the cylinder, whose speed may be controlled by a yarn tension sensor pivoted at the end of guide arm 55. The forks of several devices in a machine may be driven by toothed belt engaging a pinion attached to shaft 12. One fork may be driven from another by gearing. The revolutions of the fork may be counted by a periodically closed switch, or photoelectric or magnetic sensing. In further embodiments (Figs. 14, 15 and 17) the grooved cylinder is constituted by a straight cylinder wrapped by a helical coil. The yarn is wound for positive feed by inclined prongs mounted in a body above the cylinder. The inlet and outlet eyes are adjustable alongside the cylinder in unison. In a similar arrangement (Fig. 15) for yarn storage the spacing of the prongs is adjustable.

Title: Improvements in captive balloons
IPC: B64B1/40
Filed: 1932-11-23
Abstract: 397,347. Kite balloons. LETOURNEUR, J., 75, Rue de la Parcisse, Versailles, France. Nov. 23, 1932, No. 33112. Convention date, Nov. 27, 1931. [Class 4.] Inflatable fins for captive balloons are composed of elements of the surfaces of bodies of revolution all tangential to two spacedapart developable imaginary surfaces, each of which includes a meridian of the body of the balloon, the radii of the bases of the individual elements decreasing towards the rear of the fin. In one form, a fin applied to the underside of an elongated balloon A comprises an inclined cylindrical surface C joined to a toroidal surface or horn D resting on the envelope at c. The fin surface included between these surfaces and the envelope includes partly cylindrical elements c<1>, c<2>, c<3>, &c. of which the generatrices are all parallel to the generatrix of the cylinder C. The diameter of the cylinder c is determined by the volume requirements of the fin as is the arc b, c forming part of the axis of the horn D. The surface of the born D is obtained by considering at every point of arc b, c circles having their centres on, and their planes perpendicular to b, c and their diameters determined by the distance separating the meridians 1-2, projected through their centres, on to a plane perpendicular to a, b, each element and the horn D having a common tangent plane. The bottoms of the furrows are connected by apertured transverse partitions shown dotted in Fig. 3. The horn D may only approximate to the form described above being constructed of a series of truncated conical elements. The fin is inflated by a vent 10. In a modification the direction of the generators of the envelope surface are perpendicular to the envelope axis so that the front part of the horn is no longer a cylinder and the furrows in the fin become vertical. In a further modification, Fig. 6, applicable to a body envelope having six equal lobes, the surface of the fin comprises elements of cones which intersect the body envelope in the meridians, 21, 22 have a common tangent plane with the horn and have for their apex a point S in the plane of symmetry defined by the intersection of the perpendicular from the rear point of the envelope on to the produced axis of the front part of the horn.

Title: Improvements in locking and releasing mechanism for garment presses
IPC: D06F71/02
Filed: 1921-12-09
Abstract: 194,392. Rogers, F. H., (American Laundry Machinery Co.). Dec. 9, 1921. Ironing-machines with pressing-action only.-In a garment ironing-press, the means for operating the movable pressing member is automatically locked in depressed position and is released by actuation of a lever pivoted on, and arranged to form a toggle with the locking member. A device is also provided for throwing the locking and releasing mechanism nut of action. The invention as applied to the press described in Specification 194,391 comprises a locking member 21 for the main foot-lever 10 in the form of a lever pivoted to the frame at 20 and controlled by a spring 23. At its lower end the lever is formed with a cam guide surface 26, 27 for a pin roller 30 mounted on the side of the foot-lever 10 so that when the latter is depressed to close the press it is held by the roller passing beneath the end 28 of the locking lever. Pivoted on this lever at 31 is a release pedal 32 having a dog 34 to rest against the roller 30 in the locked position of the foot-lever 10 and a projection 35 to bear against lever 21 and thus to limit movement of the pedal in the other direction. When the release pedal is lowered it acts in toggle fashion upon the locking lever 21 to draw its lower end forwardly to free the footlever 10. When it is desired to put the locking mechanism out of use, a pedal-lever 42 pivoted to the framework at 41 is depressed so as to force the locking-lever 21 out of active position, this being effected by a pendant wedge 47 entering between the framework and a roller 31 on the locking lever. The inner end 40 of the pedal 32 is simultaneously depressed to raise the pedal as shown in Fig. 7. The pedal-lever 42 is retained in either of its two positions by a spring 43 arranged to lie above or below the pivot 41.

[Also in Group II] An X-ray sensitive photo-conductive target comprises a layer of orthorhombic lead oxide separated from a mounting plate formed of or coated with stainless steel, nickel, chromium or copper or alloys thereof by a layer of the oxide of said plate or coating metal. In one embodiment a plate of aluminium is provided with a film of stainless steel bonded thereto by spraying, electroplating or rolling. Lead oxide is vaporized on to the mounting plate at a temperature of 360-380‹ C. in an atmosphere of dry oxygen at 3-5 Á pressure. The plate is then slowly cooled and subsequently baked in air for 90 minutes at 600‹ C. to convert the oxide to the orthorhombic form and simultaneously to form a conducting oxide layer on the stainless steel surface. The vaporization and baking processes are then repeated to provide a thicker layer of orthorhombic lead oxide. Stainless steel is the most suitable metal for the mounting plate or layer since its expansion coefficient closely matches that of the lead oxide layer.
