Abstract: 950,184. Treating tobacco. J. BEFFINGER. July 6, 1960 [July 13, 1959], No. 24008/59. Heading A2C. Dried tobacco 22, in bales or loose in woven wire containers, is subjected in a ventilated chamber 11 to sufficient heat and moisture to substatnially completely ferment but not to pasteurize it. Relative humidities of up to 85‹C. may be used but in a preferred process, the tobacco is raised to a fermentation temperature of between 40‹C. and 65‹C. over about 2 days whilst its relative humidity is kept between 50‹C. and 80‹C., is maintained forcibly ventilated under fermentation conditions for from 3 to 8 days and then allowed to cool to room temperature over a day or two, initially at least under forced ventilation. Details of the process as applied to Virginia, Kentucky and Oriental tobaccos are given. In the apparatus shown, air circulation is effected by an electrically driven fan 14 between a valvecontrolled chamber inlet 12 and outlet 13, the inlet air being heated by a steam radiator 15 and humidified by steam drawn in from radiator outlets 116. A by-pass valve 20 allows optional air recirculation. The outlets 116 may be in the chamber 11, in which water sprinklers may also be provided. Re-drying of the tobacco at below pasteurisation temperature may be effected before or after the fermenting as described above, which fermenting effects up to 18% dry weight loss.

Title: Improvements in and relating to unit substations
IPC: H01H75/04
Filed: 1944-12-04
Abstract: 583,781. Switches, partly electromagnetic. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 4, 1944, No. 24220. Convention date, Dec. 3, 1943. [Class 38 (v)] [Also in Group XXXV] An automatic circuit-recloser is mounted in oil in each low-voltage insulating bushing 8 of a three-phase, step-down power transformer (not shown). On overload, a coil 22, in series with the contacts 24, 25 and terminals 17, 19 attracts a plunger 30 encircling the movable contact rod 28. The plunger strikes a projection 29 on a rod 28 and separates contacts 24, 25, thereby deenergizing the coil 22 and allowing the contacts to reclose. When the contact 25 descends, a ratchet 34 of the enlargement 29 engages a ratchet wheel 35 which is rotated counter-clockwise under retardation by an escapement 44. This movement stresses a spring 45, so that when teeth 34 disengage the ratchet wheel, the latter is returned to its normal position also under retardation, and the contact 25 rapidly closes. If the overload still exists, the contacts immediately reopen and the wheel 35 is again rotated counter-clockwise before it has been fully returned to its normal position. With continuing reopenings, the wheel 35 is rotated stepby-step counter-clockwise until a latch system 48, 49 is released by a pin 46 on a wheel 47 on shaft 42 to engage under an extension 5 and hold the contact 25 open. Reclosure is effected manually by lowering an indicator-ring 52 on a lever arm 39, which is attached to the contact rod 28, thereby freeing the teeth 34 from the ratchet wheel and allowing the latter to return to its normal position, restoring the latch 49 in so doing. The ring 52 is then released and the contacts reclose. The recloser may also be manually opened and latched by a pin 53 on lever 39 engaging a latch 54.

Abstract: 637,087. Photographic reflex cameras. ANGENIEUX, P. Aug. 16, 1946, No. 24383. Convention date, Nov. 29, 1943. [Class 98 (i)] A view-finder for photographic reflex cameras comprises, above the region where the image is formed, a reversing optical system formed of two superimposed prisms not cemented at their contact faces, the upper prism having mutually perpendicular reflecting faces forming a rooflike element with its apex edge convergent with the optical axis of the camera so as to reflect the rays issuing from the image towards the rear of the camera and the contact faces of the prisms being so inclined to the optical axis of the camera that the light rays issuing from the image and entering the optical system pass without total reflection through the contact faces into the roof-like element are reflected thereby towards the rear of the camera, are totally reflected at the lower face of the upper prism, and are directed into an eyepiece at the rear of the camera. As shown, the image is formed by the camera objective 2 and reflex mirror 3 on the ground flat face of a planoconvex lens 4. The light rays therefrom pass through a prism 12 and enter a superimposed prism 13, passing through the contact faces 15 without total reflection. The rays are reflected twice at orthogonal faces of prism 13 intersecting in the. ridge 14, are totally reflected at the contact face 15 and pass out of the system to an eye-piece 8 situated at the rear of the camera with its optical axis parallel or slightly inclined to that of the camera. Specification 637,080 is referred to. The Specification as open to inspection under Sect. 91 describes also a view-finder in which (1) the prisms 12, 13 are replaced by a single prism in which the rays after reflection from roof-like faces are totally reflected at a face coplanar with or slightly inclined to the entry face, or (2) the rays enter a prism and are reflected by roof-like faces out of the prism into a second prism cemented thereto and are totally reflected at a face of the second prism into the eye-piece. This subject-matter does not appear in the Specification as accepted.

Filed: 1927-09-21
Abstract: 285,756. Mather & Platt, Ltd., (Loepsinger, A. J.). Sept. 21, 1927. Closure members, dual closure.-An automatically opening valve, particularly for sprinkler systems, is arranged to be swung laterally from its seat by the kinetic energy of the fluid flow which it controls. As shown in conection with a dry pipe valve arrangement, the water clock h is pivoted on a horizontal pin i in an arm j itself pivoted on a vertical pin k in the valve casing a. Depending from the arm j is a curved vane or blade o. When the pressure in the dry pipe c is released, the clock h is raised slightly axially by the water pressure in the pipe b, a clearance m on the pivot k allowing of this. Water then passes into the casing a, raises the air clock e partially, and acts on the vane o to swing the clock h laterally from the pipe b. The full water stream then acts on the air clock e to open it fully, a trigger p and hook q preventing reclosing. The contact member n between the two clocks has a spherical abutment with the clock h.
