Abstract: 752,154. Draughting machines. ZUC. CHINI, C. June 16, 1954 [June 16, 1953], No. 17635/54. Class 97 (3). In a draughting machine a protractor carrying member capable of movement in two mutually perpendicular directions is adjustable on and along a support bar attached to a carriage slidably mounted on a guide bar fixed parallel to the upper edge of a draughting table, the support bar being perpendicular to the guide bar so that it can sweep over the draughting table as the carriage is adjusted along the fixed bar and the protractor may be placed in any position on the table. As shown, a draughting machine includes a fixed horizontal guide bar 1, Fig. 1, fitted by means of brackets 2 at the top edge of a draughting table T slightly behind the plane of the table, a carriage 4 running on spring-loaded rollers on bar 1 and carrying a C-shaped arm, extending slightly in front of the plane of the table, which arm supports a vertical guide-bar 5 for a protractor mounting carriage 6 slidable on spring-loaded rollers and an oblique slide bar 7 for a counter-weight 11 connected to the carriage 6 by a cable system, and a bracket 8 connecting bars 5, 7 at their lower ends and having at least one wheel running along the bottom margin of the table. Either or both carriages may have releasable means for clamping them to their respective guide bars. The carriage 6 has an extension 6<SP>1</SP> to which is secured a plate 28 on which is mounted a protractor base-plate 30 with arms 30<SP>1</SP>, 30<SP>11</SP> carrying scales 31<SP>1</SP>, 31<SP>11</SP>. The base-plate 30 is rotatable on plate 28 by means of a knob 29, Fig. 8, housing a sliding pin 36. When a knob 35 on the pin is pressed, the pin slides against spring action and, through a pivoted lever, rocks a pawl 33 out of engagement with a notch 32 on the plate 28. The protractor is then turned and, as knob 35 is released pawl 33 engages another of the notches 32, which are disposed at fixed angles round the periphery of plate 28. A pin 46 may be pressed against spring action to engage a hole 48 in pin 36 which is then retained in position to hold pawl 33 out of engagement with the notches, so that the protractor can turn freely.

Title: Improvements in or relating to door closing and checking devices
IPC: E05F3/06
Filed: 1959-05-23
Abstract: 940,644. Door closers. J. BROWN, and E. BROWN, [trading as J. & E. BROWN, ENGINEERS]. May 19, 1960 [May 23,1959], No. 17650/59. Heading E2M. In a door closing and checking device in which the mechanism is enclosed in a casing 10 adapted to be fixed to the face of a door or doorframe, the spindle 20 is journalled near its upper end in the lid 39 of the casing and near its lower end in a bearing 13 formed in a web 12 which extends across the casing, the lower end of the spindle is cranked at 51 and joined by a connecting rod 53 to a check piston 52 adapted to reciprocate in a cylinder 15, and the web 12, the bearing 13 and the cylinder 15 are formed as a separate single piece component. The web is formed with four bosses 21 which rest on bosses 22 on the inner wall of the casing and are bolted thereto, and an oil-resisting rubber sealing ring 17 located in an annular groove around the periphery of the web ensures that an oil tight compartment 24 is formed in the space below the web. The check valve comprises a tapered rod 55 which is a sliding fit within an axial bore in the piston and is arranged so that the checking action increases as the door approaches its closed position: the valve may be adjusted by a control knob 58 in threaded engagement with the cranked end 56 of the rod. A cylindrical tube 59 is also located in an axial bore in the piston and one end of the tube is connected by a coil spring 60 to the control knob 58. The other end of the tube is open and in communication with the pressure side of the piston, and a small radial port 61 is formed in the wall of tube. A similar port 62 is provided in the piston 52, the relative positions of the ports being such that they come into register just before the door is fully closed to provide a snap-shut device. A slight rotation of the control knob will cause the ports to move partly or wholly out of register, so that the knob controls both the check valve and snap-shut device. The door-closing torsion spring 25 is anchored at its ends to plates 26, 27 journalled on the spindle 20, sets of mating dogs on the plates, the web 12, the lid 39 and a carrier 29 secured to the spindle causing the spring to be wound which ever way the spindle is rotated. The plate 26 is formed in two parts, an inner ring 34 and an outer ring 63 rotatably mounted thereon. Teeth 49 are formed around the inner periphery of the outer ring and mesh with a worm 45 mounted on the ring 34, rotation of the worm causing relative rotation of the rings thereby to adjust the initial loading of the spring. A portion 40 of the lid 39 is removable to afford easy access to the worm for adjustment purposes. The axis of the worm is inclined to the horizontal plane of the plate, and a diametrical groove is formed across the end face of the worm to co-operate with a ridge on the plate to locate the worm positively at 180 degrees intervals of rotation. Specifications 940,645 and 940,646 are referred to.

Title: Improvements in or relating to methods of and apparatus for rendering powdered materials fluid
IPC: B65G53/00
Filed: 1934-06-15
Abstract: 439,819. Emptying storage chambers from below ; pneumatic conveyers. AHLMANN, N., 7, Taarnborgvej, Copenhagen. June 15, 1934, No. 17792. [Classes 78 (i) and 78 (iv)] [See also Group XVIII] In order that powdered material such as cement, cement raw meal, pulverized coal, pigments, &c., contained in weighing, measuring, transporting, or storage apparatus may behave as if it were a liquid, air under pressure is added to it, in a periodically interrupted, or continuously pulsating, current without the use of mechanical stirrers. In the case of a silo provided with a worm conveyer in its bottom to discharge the contents through a gate, the air is introduced in proximity to the worm. In one construction a container 1, Fig. 1, communicates with a chamber 20 at the end of a compressed air supply pipe 3, when the spring-loaded valves 2 are lifted by opening the cock 4. This cock is rotated continuously by a chain drive 5 at a uniform speed so that air is admitted and cut off at regular intervals of, e.g. one or two seconds. The pressure is prevented from fluctuating too considerably by inserting a chamber 6 in the pipe 3 before the cock 4. In another construction a spring-loaded lift valve has two seats 7, 8, Fig. 2, of different sizes and carries an armature 12 which cooperates with magnets 13, 14 that tend to retain the valve in its end positions. When the pressure in the compressed air vessel reaches a predetermined amount, the valve will open and the armature 12 will move to the magnet 13 and be retained until the pressure of the air on the valve has decreased sufficiently to allow the spring 15 to return the valve to the closed position. In a further construction the spindle of a lift valve is connected to a spring-loaded piston movable in a closed cylinder, one end of which is formed with an aperture through which compressed air is supplied periodically.
