Title: Improvements in endless chain conveyors
IPC: B65G23/00
Filed: 1946-01-04
Abstract: 626,209. Endless-chain conveyers. NAAMLOOZE VENNOOTSCHAP TECHNISCHE MAATSCHAPPIJ MARCHAND-ANDRIESSEN. Jan. 4, 1946, No. 420. Convention date, Oct. 24, 1941. [Class 78 (i)] An endless-chain conveyer is designed to travel at a uniform speed throughout its length by the provision of outwardly convex bridge sections between adjoining straight and curved sections. The chain is driven at a uniform speed in a curved section by means of a driving sprocket, and the bridge sections eliminate irregular motion which would otherwise occur in the straight sections, especially with long chain links. In Fig. 1 adjoining straight and curved sections of an unmodified track are shown at 1 and 2, and a bridge section at 9 joining the straight section at 4 and merging into the curved section at 5. The Specification describes the geometrical construction of the bridge section when the radius R of the curved section and the length a of a chain link are equal: the distance 4-5 across the ends of the bridge section is then equal to a chain link length. The construction of a simpler bridge section 10 which gives sufficiently uniform movement in practice is also described. The adjoining straight section 11 is tangential to it and lies outside the straight section 1 of the unmodified track. The invention is applicable to conveyers for distributing postal matter in a sorting installation. The Specification as open to inspection under Sect. 91 comprises also, Fig. 4 (Cancelled), a letter or package container attached to each link of the conveyer chain in a sorting installation. Curved plates 22, working in slots 21 in side walls 20 of the container, are pivotally mounted at 24 to arms 25 pivoted at 26 to the container and drawn together against fixed stops 28 by a spring 27. A package 32 is shot into the container at the receiving station by power-driven rollers and comes to rest on crossed extensions 221 of the plates 22, spring 27 yielding to absorb the momentum. At the discharge station, a slide 31 is operated and, through links 30, rocks the plates 22 inwardly to grip the package between their curved peripheries and eject it through the open bottom of the container. This subject-matter does not appear in the Specification as accepted.

Abstract: 891,756. Regulating tyre pressures. DAIMLER-BENZ A.G. Jan. 5, 1961 [Jan. 5, 1960], No. 571/61. Class 144 (2). Tyre pressures are increased on increase of vehicle speed, and vice versa, by means of a pressure regulator 7 controlled through a lever system by means 18, 19 responsive to changes in the vehicle speed. As shown, the tyres' pressures are regulated also in accordance with the vehicle loading by a means 17 responsive to changes in pressure in the pneumatic suspension units 15 of the vehicle. Each tyre 1 is connected to a manifold 5 communicating with a regulator valve 7 and one side of a diaphragm 9, the regulator 7 having an exhaust port 10 and a pressure air supply connection 11 fed from a reservoir 13. The valve 7 is controlled by an arm 20 which is operable by a rod 25 pivoted to the centre of a lever 26, one end of which is linked to the diaphragm 9 and the other end which is linked to the centre of a lever 27. The lever 27 has its ends pivotally linked respectively to a diaphragm 17 responsive to the pressure in the suspension unit 15, and to a diaphragm 18 responsive to the pressure developed in an air intake 19 by the speed of forward travel of the vehicle. The diaphragm 18 is common to all four wheels, but separate diaphragms 9, 17 and associated lever system is provided for the front and rear pairs of wheels. In operation, any change in pressure acting on the diaphragm 17 or 18 causes movement of the regulator arm 20 to inflate or deflate the tyre correspondingly, with corresponding movement of the diaphragm 9 to restore the arm 20 to its neutral position. In an alternative arrangement the speedresponsive means may be actuated by the speed of rotation of the wheels or associated parts.

Abstract: PURPOSE:To prevent the order of consecutive photographs from being reversed and becoming unnatural by issuing an alarm to a photographer when it is detected by a posture detection means that the film winding side of the posture of a camera is held in an upper direction. CONSTITUTION:A camera is constituted so that the photographing of one shot can be executed every window without changing the size of one frame of full size and by dividing it to plural windows. For example, in the case that three windows are provided to the respective frames, threefold consecutive photographing time is realized in comparison with the normal consecutive photographing. However, in the case of the photograph photographed by holding the film winding side of the camera in the upper direction, the consecutively photographed photographs are drawn up in an upward direction from a lower part and they become unnatural. Then, when it is checked whether the film winding side of the camera is held in the upper direction or not and the judgement is affirmed, the alarm is displayed on a display means and release is inhibitted. Thus, the photograph is prevented from becoming unnatural.
