Title: Apparatus for feeding film sheets to a film processor
IPC: G03B42/04
Filed: 1966-04-21
Abstract: 1,148,176. Feeding sheets. EASTMAN KODAK CO. 21 April, 1966 [22 April, 1965], No. 17445/66. Heading B6B. Apparatus for feeding photographic film sheets one by one from a pile 13 to a processing machine 20 comprises an inclined tray 10 carrying the pile and pivoted at its upper end 11, a suction cup or cups 33 located above the lower end of the tray, a cam 12 which raises the lower end of the tray so that the top sheet is taken by the suction cup, and a pivoted support 36 for the suction cup which is actuated by the cam 12 against the action of a spring 46 after the tray 10 has started its downward movement, to move the separated sheet forward into engagement with continuously-rotating feed-rollers 26. The cam 12 is mounted on its driving shaft 34 by means of a slot 44 with a spring 43 therein so that in the raised position of the tray the cam 12 yieldingly presses against the tray, thus preventing damage to the sheets by excessive pressure thereon by the cup 33. A motor 29 drives the cam-shaft 34, and another motor 30 drives a vacuum pump 31 connected to the cup or cups 33. The rollers 26 may be driven by a motor 25 or may be coupled to the input rollers 22 of the processing machine 20. With the loaded tray 10 in its lowest position, feeding is started by operating a main switch 27 causing motors 25, 29, 30 to operate. The tray is raised until the top sheet is engaged by the suction cup 33 whereupon the tray starts its downward movement. The cup 33 is then moved towards the rollers 26 by the action of cam 12 on a bar 35 fixed to the support 36 to carry the separated sheet forward. A spring-pressed pivoted arm 39 engages the lower end of the pile 13 and bends that end of the separated sheet downwardly to assure separation of the sheet from the underlying sheets. When a sheet enters the bite of the rollers 26, a switch 28 in the circuit of the motors 29, 30 is opened by the rollers so that the tray is arrested and suction is cut off until the sheet passes beyond the rollers. Another switch in parallel with switch 28 is operable by an adjustable cam on the cam-shaft 34 so as to adjust the time the circuits are broken and thus vary the spacing of the sheets as they are fed to the machine 20. A further switch 45 opened by the support 36 at the end of its forward movement also operates momentarily to break the circuits of motors 29, 30 to ensure release of a sheet from the cup 33 at the end of the forward movement of the support 36. If more than one sheet passes between the rollers 26, a further contact of switch 28 is operated to stop all the motors 25, 29, 30 and to cause a buzzer to be energized. Holes are provided in the bottom of the tray immediately below the cups 33, so that if no sheets are on the tray, the tray does not adhere to the cups. A number of side-by-side piles of sheets may be carried by a single tray and a single cup 33 provided for each pile. It is arranged that when the main switch 27 is actuated to stop the sheet feed, the apparatus comes to rest with the tray in the lowermost or loading position.

Abstract: 384,587. Aerofoil structures. BUDD MANUFACTURING CO., E. G., 2500,Hunting Park Avenue, Philadelphia, U.S.A.-(Assignees of Ragsdale, E. J. W. ; Curren Terrace, Norristown, Pennsylvania, U.S.A.) June 23, 1932, No. 17737. Convention date, June 23, 1931. [Class 4.] An aerofoil comprises spaced ribs interconnected by angle-section longitudinal members, each having an arm extending into marginal slots of the ribs and another arm secured to marginal flanges of the ribs, while a metallic skin is secured to the ribs and longitudinal members to constitute therewith a rigid structure. As applied to one wing or blade of a rotary wing system ribs 10 formed in one piece stampings from light gauge sheet metal have upper and lower flanges 11 and oppositely flanged lightening holes 16. The ribs are spaced closely at the root 14 where the blade is to be attached to a hub member and at 15 where a bracing member is to be secured, and are interconnected by a series of angle-section longitudinals 18 of light gauge strip metal. The flanged edges of the ribs are formed with a series of kerfs 19 corresponding to the number and position of the longitudinals 18. One arm 20 of the members 18 is inserted into the corresponding kerfs of the ribs which are held in a jig and the other arm 21 spot welded to the flanges 11. Vertical angle members 22, Fig. 1, have one arm welded to the web of the rib and the other arm which vertically overlaps vertically opposed longitudinals welded to their arms 20. The sheet-metal wing covering is made in upper and lower portions flanged inwardly at their forward edges which are located in kerf 28, Fig. 2. Either the lower or upper portion of the wing covering is first assembled by first engaging the flanged forward edge in kerf 28 then spot welding to longitudinals 18 and rib flanges 11. The remaining portion of the covering is then applied, its edge flange being inserted in kerf 28 and welded to the flange of the other sheet, then the sheet progressively welded to longitudinals and ribs from leading to trailing edge, the flange 10 being cut away at 13 to permit easy access of welding tongs to the covering as the trailing edge is approached. Finally the overlapping trailing edges of the covering are welded together. In an alternative method, the forward edge flanges of the covering sheets are welded together then located in kerf 28, the lower section then welded to the framework with the upper section bent forwardly out of the way, and finally the upper section attached progressively to the framework as before. The wing tip 28<1> is formed from two shaped sheets lap welded together at the leading edge and spot welded at their abutting trailing edges. The wing tip is reinforced by ribs 31 welded to the skin, the inner rib being spaced from the mouth of the tip to permit the ends 32 of longitudinals 18 to telescope some distance into the tip to the skins of which they are welded. The tip is assembled before the main covering sheets.

Abstract: 1,136,888. Thermal switches. DANFOSS A.S. 18 April, 1967 [29 April, 1966], No. 17759/67. Heading H1N. [Also in Division G1] A bi-metal operating device for a switch 14 comprises operating means constrained for displacement by at least one bi-metallic element in a first plane and an ambient temperature compensatory bi-metallic element 16 displaceable in a second plane normal to the first plane, the operating means having an edge 23 adapted to engage the compensatory bi-metallic element. As shown, in an overload relay, three bi-metallic elements 2, 3, 4 are connected to terminals 5, 6, 7 of a three phase mains network and the operating means comprises slides 8, 9 which actuate a pivoted rocker arm 10. Movement of any one or all of the elements 2-4 displaces the slide 8 which therefore causes the rocker arm to pivot about the point 12 and operate the switch 14. The element 16 is U-shaped and has a stop 15 which engages the inclined edge 23 of the slide 9. The position of the stop is adjustable in the plane of movement of the slide by a screw 18 and in a direction normal to this plane by a pointer 20, the element 16 pivoting about the screw. Movement of the stop therefore adjusts the position of the slide 9 and the excess current necessary to operate the switch is given by the position of the pointer on a scale 21. In a modification (Fig. 4, not shown) for a single phase excess current responsive device, the inclined edge is formed on the rocker arm and a straight compensatory bi-matallic element is incorporated.

Title: Improvements in or relating to method of forming solid or shaped bodies from aggregate particles and the products resulting therefrom
IPC: C04B33/13
Filed: 1945-07-12
Abstract: Shaped bodies, ramming mixtures and mortars, and refractory materials are prepared from non-plastic aggregate particles by forming a dispersion in a liquid medium of a part of the bonding-agent and incorporating this into the aggregate to form a thin covering on the particles, the remainder of the bonding-agent being separately incorporated as a finely divided solid in a subsequent operation. The aggregate which may be of porous or non-porous character is graded to obtain a densely-packed batch under pressure.  The bonding-agent may be a single material, two or more materials capable of reacting to form a bonding-agent, or a bonding-material and an adhesive.  The bonding-material or the part to be incorporated first, is made into a dispersion or solution with the whole of the water or other tempering liquid and is thoroughly mixed with the aggregate, and after the grains are coated the remainder is mixed in dry, the mixing being accomplished in such a way as not to affect the grading of the aggregate particles.  The mixture is then pressed to shape at at least 1000 lbs. per square inch dried and fired. When periclase is to be bonded, the bonding-agent may consist of silica or a correctly-proportioned mixture of silica and magnesia so that a bond of forsterite is produced, and a solution of magnesium chloride is employed as the tempering liquid; preferably volatilized silica is employed.  Alternatively, a dispersion of a glue or other glutinous material, or a clay slip may be employed.
