Title: Improved process for coating metals such as iron and steel with lead
IPC: C23C2/10
Filed: 1931-03-24
Abstract: Metals such as iron or steel are coated with lead by applying molten lead to the heated surface of the metal to be coated in an atmosphere of chlorine or hydrogen chloride or a mixture of these gases.  The atmosphere may be provided by a hydrogen-chlorine burner or a jet of chlorine or hydrogen chloride may be used in conjunction with a coal gas-air, coal gas-oxygen, oxy-acetylene, or oxy-hydrogen burner.  The jets from the burners may be played on to a stick of lead held close to the surface to be coated.  The interior of a tube may be coated by heating the tube to 500-700 DEG  C. by slow rotation over a gas burner, inserting sufficient lead to form a coating of the required thickness and passing chlorine or hydrogen chloride through the tube until a coating forms.  The stream of gas and the heat supply are then cut off and the tube rotated at a speed sufficient to distribute the molten lead evenly over the tube, the rotation being continued until the lead has solidified.  In coating large iron or steel surfaces with sheet lead the surface may be coated with lead locally in points or bands by the process described above and the sheet lead then burned on to the treated surface.

Title: Photographic camera
IPC: G03B19/04
Filed: 1964-03-04
Abstract: 1,048,877. Roll film cameras. AGFA A. G. March 4, 1964 [Oct. 1, 1963 ], No. 9096/64. Heading G2A. The film 5 in a roll film camera is transported from a spool-less supply cartridge 3 to a spool-less take-up cartridge 4 by means of a sprocket 21, driven by means not shown and engaging in the film perforations. To the back cover 2 is fixed a latching spring 6 having a hooked end 7, this end being normally held clear of the film by the takeup cartridge itself. If, however, cartridge 4 has not been inserted into the camera, or not inserted properly, the end 7 of spring 6 is positioned in the film path, and so prevents further film advance. A lever 18, having two arms 18a, 18b, is biased by a spring 19 so that, when no take-up cartridge is present, a marker lug 20 on arm 18b is positioned between the lenses 16, 17 of the viewfinder. Thus when lug 20 is visible in the viewfinder, it is a warning that the take-up cartridge has not been inserted. When the cartridge has been properly inserted, it bears against arm 18a, so pivoting lug 20 out of the viewfinder field. Fig. 2 (not shown) is a modification in which the lever 18 itself has an extension which blocks the film advance path when cartridge 4 is not present.

Title: Improved mechanism for producing step by step motion
IPC: B41L11/00
Filed: 1941-07-23
Abstract: 547,640. Step-by-step mechanism; duplicating machines. FORD, F. R. July 23, 1941, No. 9288. [Class 80 (iii)] [Also in Group XVI] Consists in means for moving a member stepby-step or through any number of steps in one movement by hand in either direction. The invention is particularly applicable to office appliance machines and it is described as applied to the feed tray of a duplicating machine described in Specification 538,163, [Group XVI]. The tray 28 is supported on a pair of bars 27 and, on its underside has a block 100 containing a spring-pressed plunger 101 which projects into a hole 104 extending through the block. The machine has a moving carriage 105 carrying a bar 106 which passes through the hole 104 and in which is formed a helical groove 107 engaged by the plunger 101. The tray can be pushed sideways over the carriage any number of spaces in either direction by handles 108; the plunger and groove serving to check the movement. For the step-by-step movement, Figs. 3, 4, brackets 109 forming part of the carriage 105 have fixed projecting pins 110 and, mounted to move over these pins are two rack bars 111, 112 having teeth 113, 114 of ratchet form. The bar 111 has two cam slots 115 each having its left-hand end 116 turned downwardly, and the bar 112 has two slots 117 each having its righthand end 118 inclined downwardly, the slots in both bars engaging the pins 110 at their inclined ends. The bar 111 is urged to the right by a spring 119 and the bar 112 to the left by a spring 120. The upper edge of bar 111 has a cam surface 121 engaged by a pin 122 projecting from the back of the bar 112, and the bar 112 has a cam surface 123 engaged by a pin 124 projecting from the front of bar 111. On its upper side the feed-tray has a bracket 125 Fig. 2, formed with a web 126 on opposite sides of which are detents 127, 128 oppositely arranged and pivoted at 129,130. Each is acted upon by a spring 131 the detent 127 being pushed against a stop 132 and the detent 128 against a stop 133. The teeth 114 are adapted to engage the detent 127, and the teeth 113 the detent 128. The teeth are normally out of engagement with the detents and the tray can be moved any required distance by the handles 108. To obtain the step-by-step movement, one of the rack bars is operated. If the bar 111 is pushed to the left, its cam slot causes it to move downwardly and to the left and brings one of its teeth into engagement with the detent 128. At the same time the pin 124 acts upon the cam surface 123 of bar 112 to force the latter down and slightly to the right to bring one of the teeth 114 into a position to engage the detent 127 and act as a stop to limit the length of the movement. When the bar 111 is released both bars return to their original position. A similar movement, except that it is reversed, occurs when the bar 112 is pushed to the right. Specification 545,562, [Group XVI], also is referred to.

Title: Improvements in and relating to aircraft with sustaining rotors
IPC: B64C27/02
Filed: 1937-04-06
Abstract: 492,816. Aircraft with rotary - wing systems. CIERVA AUTOGIRO CO., Ltd., and BENNETT, J. A. J. April 6, 1937, No. 9799. [Class 4] In a sustaining rotor for a gyroplane adapted for a " jumping take-off " including an articular mounting for a rotor blade comprising a pivot leading and lagging displacement on which is compounded with a change of blade pitch, further pivot means permitting leading and lagging of the blade independently of the displacement on the other pivot and stops to limit the displacements at least in one direction, the parts are so disposed or additional means are provided so that when the rotor is rotating, but not driven, the action of centrifugal force positively locks the first pivot in the position corresponding to the maximum operative pitch angle of the blade, the second pivot being free. In one form, the rotor blade 19 is articulated to a stub 17 by a pivot 18 which may be inclined, with reference to the direction of rotation, backwardly and upwardly, or with reference to the hub axis, forwardly and upwardly, or both, or may be parallel to the axis of rotation. The stub 17 is pivoted to trunnions 16 of a trunnion-block 13 mounted in journals 15 in a hub 11 rotatable in bearings 12. The axis of the journal 15 is upwardly and outwardly inclined with reference to the rotor-axis. The block 13 is provided with a lever 20 adapted to be engaged, when a shaft 22 is driven, by a projection 21. The lever 20 moves in a slot which limits movement in the journals 15 and, during flight, movement in these journals is prevented by the action of centrifugal force, the axis of the blade being offset from the intersection C of the axes of the trunnion-block and preferably a stop is provided to limit leading displacements on the pivot 18. In a modification, the locking is obtained by the action of centrifugal force on a lever provided with a projection adapted to engage a recess in a plate secured to or integral with the trunnion-block. In this latter construction, care is taken that the offset cannot become zero or change its sign and the axis of the pivot 18 may be inclined inwardly and upwardly with respect to the blade axis. In one construction in which the axis of the pivot 18 is parallel to the hub axis, the pivot is provided with a friction damper. In further forms, the axis of the journals 15 is inclined inwardly and upwardly with respect to the hub axis, the lever 20 is disposed on the outside of the trunnion-block and the locking is obtained by a pivoted weight or by off-setting the line of action of the centrifugal force. In a still further form, the inclined axis AO, Fig. 8, is virtual, the stub 17 being free to turn in a trunnion-block 32, an arm 35 on the stub engaging a fulcrum 36. Specification 474,681 is referred to. The Provisional Specification describes also rocking the blades onto lagging stops on the application of a brake after landing.
