Abstract: 494,524. Shutters in photographic cameras. BRONZAVIA SOC. ANON. April 26, 1937, Nos. 11948 and 11949. Convention dates, April 25, 1936 and March 22, 1937. [Class 98 (i)] A photographic camera has a focal plane shutter which comprises two blades defining a slot between them and a control member for adjusting the blades relatively, the member being normally out of engagement with the shutter parts but adapted to be coupled with the shutter to effect adjustment of the blades. The two blades 9, 10 of sector shape are relatively adjustable on a spindle 11 and define an aperture slot. The blade 9 is fixed to the spindle, whilst the blade 10 is mounted on a pinion which can be coupled to the spindle 11 through a comb-like part 14, a spring 15 tending to hold it in this position. A rod 16 with a graduated knob 17 has a tooth 16a and a bevel pinion 18 such that when the knob is pressed in against a spring 19, it first swings the comb like part 14 about its pivot to uncouple the two blades 9, 10, and then engages the pinion 13 whereby the blades can be relatively separated. The rod 17 can only be turned when it is pushed in, being normally retained from rotation by notches on the knob engaging the pointer 32. In a modification, Fig. 3, the rod 16 carries at its free end a plate 100 with pins 101 which can engage holes 102 in a driving device for the blade 10. This device comprises a toothed wheel 103 which is connected through worm gearing with a sleeve 107 carrying the blade 10. A pinion 17<1> and teeth 132, and a pawl 108 acting on the worm gearing both lock the shafts in their correct relative positions and are released when the knob 17 is pressed in. An exposure indicating device may be coupled with the rod 16. The shutter is tensioned by a spring 20 which is rotated by means of a pinion 24, rack 21, rod 22 and handle, and is retained in set position by pawl-and-ratchet mechanisms 25, 26 and 28, 29. The release mechanism includes a pawl 33 with a finger 33a, which engages a groove in a fixed abutment 33b. The pawl is released by a lever 37 which when rotated lifts the finger out of the groove and allows the shutter to run down. The camera casing 1 has several lenses and contains a chamber 3 in which are placed the film magazines 5 and the film driving drums 6. The Specification as open to inspection under Sect. 91 also comprises a catch 67, Fig. 4 (Cancelled), for the lid of the chamber, which catch drives a pinion 68 and opens the magazines when the lid is closed. It also comprises the subject-matter of Specifications 494,384 and 494,709. This subject-matter does not appear in the Specification as accepted.

Title: Backflow prevention unit
IPC: E03C1/10
Filed: 1962-03-29
Abstract: 1,006,566. Water supply systems. D. G. GRISWOLD, F. K. WYCKOFF, M. M. CHARD and W. S. GRAU. March 29, 1962 [June 26, 1961], No. 12156/62. Heading E1X. [Also in Division F2] A water back flow preventive device comprises an inlet 6, Fig. 3, for connection to the supply main and an outlet 10 to the point of use, the device being provided with two check valves 1 and 2. A zone Z between the two check valves can be connected to atmosphere through a valve 12 which comprises a valve closure member 84 which is connected by a stem 78 to two diaphragms 110, 117 which form walls of chambers 132, 131, the chambers on the opposite sides of the diaphragms being connected to atmosphere by passages 104, 137. The chamber 131 is connected by a passage 13 to the inlet of the check valve 1, the pressure in this chamber acting on the diaphragm 117 to close the valve 12. The chamber 132 is connected by a passage 14 to the zone Z at the inlet of the second valve 2 and the pressure in this chamber acts on diaphragm 110 which, in conjunction with a spring 130, tends to open the valve 12. In operation under normal flow condition the valves 1 and 2 are open and the valve 12 is closed due to the pressure differential across the valve 1, the pressure at the inlet of valve 1 being sufficient to hold the valve 12 closed. If the supply pressure drops or fails the check valves close and the valve 12 opens to drain the zone Z. Further the valve 12 will also drain any leakage back past the second check valve to prevent syphoning. The spring 130 is preferably calibrated or adjusted such that the valve 12 will open when the pressure differential across the valve 1 falls below 2 p.s.i. The seat of valve 12 is shaped to prevent any tendency of the flow through the valve to close this valve. Alternative angles of slope of the seating member are given in the specification. Each check valve comprises a hinged closure member 26, Fig. 5, cooperating with a bevelled seat of about 5 degrees. The closure member is pivoted at 38 and is connected by a toggle lever mechanism, comprising links 34, 45, to the valve housing. The links 34, 45 are pivoted at 48, the pivot being loaded by a spring 54 tending to straighten the links. The link 45 is preferably 4 times as long as the link 34. The loading of the spring of check valve 2 is preferably slightly less than that of check valve 1.

Abstract: 763,372. Making heading dies; extruding. AMERICAN SCREW CO. April 28, 1954 [April 29, 1953], No. 12370/54. Classes 83 (2) and 83 (4). A header die 30, Fig. 5, for use in retaining a wire whilst a head is upset on one end thereof, is made by confining an unhardened steel blank 25, Fig. 4, in a housing 27 and pressing the projecting end 21-24 of a hardened and polished punch 19 into the blank to form it into the desired orifice profile, Fig. 5, whereby any irregularities produced in the orifice will extend longitudinally. The upper end of the die is subsequently ground flat and the die is hardened. The blank may have a drilled hole of slightly smaller size than the end portion 21 of the punch. During pressing an intermediate portion 23 of the punch undergoes elastic deformation and produces a shallow rounded annular recess 31 in the die orifice. The shank of a blank to be headed is upset into the recess during the heading operation and this prevents the blank from being pulled out of the die by the heading tool, especially when socketheaded screws are being made. Various forms of header die for producing screw blanks with protruding or countersunk heads or with chamfered-ended shanks are shown and described, and in one form, Figs. 12, 13 (not shown), the punch is pressed part-way into a solid blank and afterwards a hole is drilled from the other end of the blank to meet the pressed orifice. Extruding. In one form of die, Fig. 16, an extrusion orifice 42 is provided through which is extruded that part of the shank of a screw blank which is to be threaded. A concave recess 43 prevents witdrhawal of the blank with the heading tool.
Patent GB-124208-A (GB)
Abstract: 124,208. Gowen, A. V., (Representative of Lecesne, N.). March 25, 1916, [Convention date]. Drawings to Specification. Alumina.-In the production of artificial corundum by the fusion of a charge of bauxite and anthracite in a shaft furnace, as described in Specification 102,507, a layer of corundum is preferably placed on the furnace grate under the charge, and an open-ended metal cylinder is stood inside the furnace to receive the charge, leaving a space between itself and the furnace walls which is filled with granulated bauxite or corundum to protect the walls, after which the metal cylinder is lifted out and the furnace is set in operation. Some porous corundum or its dust, such as the product described in the above-mentioned Specification, may be fixed with the furnace charge. If it is desired to obtain the titanium of the bauxite in the form of ferro-titanium, the blast is somewhat reduced so as not to expel the iron from the furnace. For use as an abrasive, the fused bauxite retained after grinding is subjected to a strongly oxidizing combustion with a sufficiently rapid current to expel the ash of the remaining carbonaceous matter. For making grindstones agglomerated by fusible matter, the ground material is moulded without taking any precautions as regards dust and the carbonaceous matter present, and the grindstones are roasted in an oxidizing atmosphere, the ash being expelled as above-mentioned.
