Title: Improvements in weighing scales
IPC: G01G1/00
Filed: 1927-01-24
Abstract: 276,559. Marks, E. C. R., (Toledo Scale Co.). Jan. 24, 1927. Pendulum - weight apparatus; links and stays. - In a weighing scale the means for maintaining the commodity receiver in an horizontal position during weighing movements of the scales lever on which the commodity receiver is mounted consists of a frame mounted on knife-edge pivots having axes at an angle to the axis of the load pivots of the lever. The scale lever 9, fulcrumed on stands 5 projecting from a base 1, supports on load pivots 10 a platform spider 11 which is provided with forwardly and rearwardly extending arms 21, 22 each coupled by a pull and push link 23 to a frame 20. The frame 20 is pivoted upon knife-edge bearings 16, 17 arranged at right angles to the load pivots 10, and as shown in Fig. 2 extends transversely of the scale lever and by reason of its link connection with the spider 11 prevents tilting of the platform. Disarrangement of the bearings 16, 17 is presented bv screws 26, 27 carried by a base bracket 28. the lever 9 is coupled as usual to a pendulum lever 39 and computing drum 41. A weight 12 is removably secured to the scale lever for counterbalancing the platform and associated mechanism. Casings.-The lever mechanism is enclosed by a base cover 29 held in place by a nut 30 screwing on to a part 31 extending from the base 1. Secured to the rear of the base is a housing support 34 surmounted by an upright housing 38 containing the load-counterbalancing mechanism. The joints between the housing support 34, the base 1 and the base cover 29 are made tight by means of gaskets. A portion 35 of the housing support extends under the base cover and carries a level 36 visible through a window 37. A removable cover plate 42 affords access to the nose of the scale lever. Vibration, preventing and neutralizing.- Vibration is controlled by a dash pot 43 from which a plunger rod 44 extends through the base cover 29 to the platform 33.
Patent GB-233020-A (GB)
Title: Improvements in or relating to lighter-than-air craft
IPC: B64B1/00
Filed: 1924-01-26
Abstract: 233,020. Airship Guarantee Co., Ltd., and Wallis, B. N. Jan. 26, 1924. Aerostats.-For producing a gas container for balloons, and rigid or non-rigid airships of any desired shape, the wires forming the network or networks surrounding the aerostat or aerostats are so varied in pitch in the different zones from top to bottom that when subjected to the pressure of the inflated aerostat or aerostats the network or each network deflects to the desired curvature, the wires or certain of them being attached for this purpose to longitudinal member or members or to a longitudinal locating strip or strips. The same result may be obtained by varying the tension in each wire in relation to its angle of inclination to the axis of the ship, the load per foot. run being maintained constant or at the desired figure by spacing out the wires towards the regions of lower pressure; or, keeping the tension of all the wires constant the load per foot run and the angle of inclination of the wires may both be varied. To produce a cylindrical aerostat the load on the wires is maintained constant and normal by selecting the size of the mesh in the panels from top to bottom of the aerostat in accordance with the diminishing radial pressure as shown in the development in Fig. 1 The ends of the wires in each panel are secured to eyelets in longitudinal spacing strips or wires 2 and to eyelets on the frame rings 1 or wires attached thereto at the junctions of the frame rings and longitudinal girders. The longitudinals 2 also are secured to these junctions. Fig. 3 shows one half of the developed network extending from top to bottom of the airship on one side when the inclination of individual wires is suited to the load per foot run. In this case only two longitudinal spacing strips 2 are employed the remaining strips or wires 3 serving ony as supports for the wiring when the aerostat is collapsed. The constant tension of the wires is determined by that of pilot wires 6, 7 which may be set at any desired inclination. The wires of the network ommited from the drawing are similar but laterally reversed in inclination. Fig. 5 shows the application of the invention to the network between adjacent aerostats, the wires 14 being of increasing pitch towards the bottom so as to deflect to a spherical curve under pressure. The wires may be initially untensioned if self supporting frame rings are employed as described in Specification 233,021 or they may be initiallv tensioned and serve as bracing. Their ends are attached to eyeplates hinged to the rings. The network transmits the lift loads tangentially to the frame rings and consesequently the cars may be suspended at the sides of the airship in the space between the gas containers and the outer cover.

Title: Improvements in or relating to the recording of colour television images
IPC: H04N9/11
Filed: 1954-01-25
Abstract: 756,696. Television. TECHNICOLOR MOTION PICTURE CORPORATION. Jan. 25, 1954 [March 9, 1953], No. 2164/54. Class 40 (3). In an arrangement for recording colour television images on lenticular kinematographic film separate component images are reproduced by individual picture tubes and directed on to the film via a lens and a mirror being interposed in the optical path between at least one of the picture tubes and disposed to reflect the image on this tube to a predetermined entrance area of the lens so that this image is directed on to the film along a separate optical path. Fig. 1 shows one embodiment in which the red and blue component images are reflected on to the lens L over separate optical paths rand b by means of mirrors Mr and Mb respectively the green component image being directed over optical path g on to an area of the lens L lying between the entrance areas of the red and blue component images. To enable the amount of light from each component image to be varied to effect correct colour balance the mirrors are provided with knife edges at their inner edges (to sharply define the green entrance area) and are adjustable in the plane of their reflecting surfaces (Fig. 2, not shown). With this arrangement the picture tubes may be selected to produce maximum intensity of light emission in the region of maximum sensitivity of the film emulsion and the use of colour filters is avoided since the optical arrangement in co-operation with the film lenticules ensures that the three colour aspects are kept separated on the film. The film may be conventional positive or negative monochrome stock and to avoid moire effects with respect to the scanning lines the film is lenticulated longitudinally.

Inventor: ZERNA WOLFGANG
IPC: E04C5/12
Filed: 1957-01-23
Abstract: 804,360. Pre-stressed concrete. HOLZMANN A. G., P. Jan. 23, 1957, No. 2461/57. Class 20(4) [Also in Group XXV] Tensioning wires, preferably for prestressed concrete, are anchored to a thickwalled, heat-treated steel tube 1 having a substantially elliptical mouthpiece at one end through which passes at least one tensioning member 2 which is secured within the tube by a sealing mass of concrete 3. The elliptical mouthpiece is formed by flattening the tube 1 and to secure effective anchorage the wires 2 are spread out behind the mouthpiece and around a small steel tube 4. The embedded length required for each wire 2 which is of oval shape is shortened by twisting each wire twice through 90 degrees. At the end remote from the flattened mouthpiece, the tube 1 has a screwthread 5 on which a nut 6 transmits tension from the wires 2 to a steel plate 7. The tensioning member is protected from the surrounding concrete by an envelope 8 which provides an annular space which is finally filled with concrete mortar through the tube 4. The steel tube 1 may also be used with wires 2 twisted as before as an intermediate tensioning head and may be left within the concrete. Internal screw threads may be provided within the tube and are staggered in relation to the screw-threads 5 so that the tube wall is not weakened. The interior of the tube may be roughened so as to provide a firm seat for the sealing concrete 3. The anchoring nut is made of two or more segments 12 to facilitate removal and are connected together by bolts 13. The flanges have wedge shaped notches 14 so that the segments 12 can be separated on insertion of a chisel; Figs. 11 to 13 (not shown) illustrate variations of round tensioning wires which may be used with a shorter seal in the tensioning head and comprise corrugated wire, wire with a pr-tensioned helically wound wire about it or a corrugated wire wound helically with a pretentioned wire; Fig. 14 (not shown) iillustrates apparatus for pressing concrete into the tensioning head which comprises a rubber piston urged by a hydraulic jack into the concrete in the tube which is compressed and encases the tensioning wires. The other flattened end of the tube is substantially blocked during the process so that only a small quantity of concrete may escape. The device may also be used for tensioning cables of suspended roofs or ties of double-hinged frames.
