Title: Improvements in, or relating to, constructional metal frameworks for buildings
IPC: E04B1/24
Filed: 1943-10-09
Abstract: 574,559. Metal framed buildings. HILLS PATENT GLAZING CO., Ltd., and HINCHLIFFE, E. D. Oct. 9, 1943, No. 16557. [Class 20 (ii)] The metal framework of a building is so constructed as to be incompletely rigid in itself, complete rigidity being derived from the covering material, e.g., bricks or blocks, of the structure. The units from which the framework is erected comprise longitudinal booms 5 interconnected and braced by two staggered sinuous or zig-zag members 6 secured by spot-welding. The units are designed for loads applied only in the plane of their webs lateral stiffening being derived from the covering material such as bricks 11, Fig. 3, secured to the stanchions by bent members 12 set in the mortaring. Where the covering material is block-work, bent members 14, Fig. 4, may be used, which serve as dowels for the blocks. Alternatively the ends of bent members such as 12 may be bent outwardly in the plane of the member so that it may be set in the cement between adjacent blocks. The units are disposed so that their webs are perpendicular to the covering material. Floor blocks may have lugs on their under faces, the floor blocks interfitting in their own plane whilst the depending lugs embrace the longitudinals of the floor beams. In a modification stops may be welded to the upper longitudinals of the floor beams, the floor blocks having their corners removed to accommodate the stops thereby preventing lateral sway of the floor beams, plates which overlap adjacent blocks being secured to the stops by screws. Ceiling blocks 21 may rest on the lower booms and be secured by a transverse wedge 22, Fig. 8, engaged between the intersecting sinuous members of the web; or the ceiling blocks may be suspended from the lower booms by clips 23, Fig. 9, each having a pair of oppositely-facing tongues 25 to carry adjacent blocks. Specifications 565,678, 566,084, 570,998 and 574,021 are referred to.

Title: Pulse radar
IPC: G01S13/532
Filed: 1972-04-12
Abstract: 1379496 Doppler radar PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 12 April 1972 [15 April 1971] 16841/72 Heading H4D A pulse radar includes means sensitive to the amplitude of the transmitted pulses to prevent echoes reaching an evaluation unit if the amplitude is below a predetermined threshold. A scanning pulse Doppler radar utilizing coherent detection utilises a control unit 23  to enable AND gates 32 to successively energize sample and hold circuits 20 during a transmitter period. Thus the echo signals are passed to high pass filters 22 each representing a range increment and whose outputs feed indicator 24. A directional coupler 26 senses the transmitted pulse amplitude and after detection video pulses are fed to logic 31 which blocks gates 32 if the amplitude is low or a pulse does not follow a trigger pulse from sync. generator 11 within a predetermined time. The arrangement prevents saturation of the digital high pass filters over several transmitter periods due to sudden loss of signal because of an omitted transmitter pulse.

Filed: 1930-05-31
Abstract: 354,448. Locomotives. SKODA WORKS, PLZEN, 37, Jungmannova, Prague. May 31, 1930, No. 16888. Convention date, June 11, 1929. [Class 79 (i).] Each of the underframes of an articulated locomotive is mounted upon a pair of bogies by means of central spherical bearings 5, Fig. 2, while the lateral tilting is controlled by side supports on each bogie in the form of bell-crank levers 6, 8, 9 and 6<1>, 8<1>, 9<1>, the free arms of which are connected by a longitudinal rod 9, 9<1>, Fig. 5. Preferably a corresponding pair of connected supports 7, 71 is provided on the opposite side of the locomotive. In the arrangement shown in Fig. 5, the bell-crank levers are connected to the bogies by ball joints 6, 6<1> capable of sliding movement, and to the locomotive frame at the points 8, 8<1>. The full lines indicate the normal running position of the levers, while the dotted lines diagrammatically represent the displacements which occur when the leading bogie, i.e. the one bearing the supports 6, 7, has reached a curve and the elevation of the outer rail has effected a tilting of the bogie, the rear bogie not having reached the curve. The points of support 8, 81 of the locomotive frame are raised to the sameextent, thus minimizing torsional stresses in the frame, while the angle of tilt is approximately half that of the leading bogie. In a modified construction, Fig. 7, the levers have a sliding connection at the points 6, 6<1> with the locomotive frame and are connected at the points 8, 8<1> to the bogies, the arrangement in this case, when the vehicle reaches a curve and the bogies radiate, effecting a separation of the points 8, 8<1>, elevating the points 6, 6<1>, and thus giving the locomotive frame an additional tilt to counteract centrifugal force.

Title: Improvements in or relating to mountings for photographic cameras
IPC: G03B35/24
Filed: 1948-06-24
Abstract: 656,165. Photographic cameras. DUDLEY, L. P. C. J. June 24, 1948, No. 17028. [Classes 97 (i) and 98 (ii)] A mounting for a photographic camera of the kind in which there is provision for relative movement between a line or lenticular screen and the light-sensitive film or plate in the production of stereoscopic pictures of the parallax panoramagram type, comprises a carriage mounted for linear movement on a support, a platform carrying the camera mounted on the carriage, and means pivotally connected to the platform and to the carriage and co-operating with a cam rail in such a way that the platform is moved angularly with respect to the carriage pursuant to the linear movement thereof, the angular movement being so correlated with respect to the linear movement of the platform that the optical axis of the camera always passes through a chosen fixed point. As shown in Fig. 3, a carriage or frame is slidable on rails 1, and a camera 2 is mounted on a platform 5 supported on the carriage by a pivot and supporting castors. The carriage is moved by a chain 12 attached thereto at its ends and passing over a driving sprocket 13, an idler sprocket 14, and a guiding sprocket, not shown, beneath the carriage. The platform 5 is rotated during this movement by a bell-crank lever 22 pivoted to the carriage, carrying a roller 23 at one end and linked at the other end to the platform. Lever 22 is spring-loaded so that roller 23 rides on a cam-rail 19 adjustably mounted on extensions of the frames 3. Springs acting on the platform take up backlash. The lens board 16 of the camera is moved in guides 17 on the platform 5 by a lead screw 18 driven by a flexible coupling 33 through a gear-box 34 from an electric motor 36. A handle 35, connected to a differential in the gear-box, is used to adjust the initial focus. The motor 36 also drives the sprocket 13 through a differential gear-box 37, to which is coupled an adjusting handle 38. As the carriage moves on the rails, the platform is turned by its linkage to face a fixed point, and the camera focus is adjusted to this point by means of gear-box 36, which causes the focal distance to decrease to a minimum at the mid-point of the carriage travel, where the optical axis is preferably at right angles to the direction of travel of the carriage and thereafter to increase. The carriage may be moved on rails 1 by a rack-andpinion mechanism, or by hand instead of by a motor. The frame may be adjustable in length and collapsable. The whole camera, and not just the lens board, may move to maintain focus. According to the Provisional Specification, platform 5 may have a shaft in bearings on the carriage and carrying a pinion engaged by a rack, one end of which rides on bar 19. The correlated rotation of the platform may be effected by two constant-speed motors or a common drive through variable-ratio gearing or cam mechanism, or by two motors, the speed of one of which is variable.

Abstract: 1,261,009. Coffee percolator. ELECTROSTAR G.m.b.H. April 10, 1970 [April 25, 1969], No. 17203/70. Heading A4D. A coffee percolator comprises an annular water container 2 around a filter funnel 1 into which a rising and falling tube 8, 11 discharges. The rising tube 8 is partly enclosed in a water heating pipe 18 surrounded by an electrical heating element and inserted into a sleeve 5 supported in the water container 2. Water passes through a one way valve 7 and into the water heating pipe 18 and ring pipe 8, when poured into the container 2, air being displaced from hole 24 in tube 8. Electrical heating element 21 then heats up the water in the water heating tube until the increasing vapour pressure forces valve 7 into a closed position whereby hot water is forced through the rising and falling tube on to a sieve plate 13 and into the filter funnel in which coffee is infused. When the vapour pressure decreases to below the pressure of the water in the container water will again be forced through valve 7 into tubes 8 and 18. Packing 23 prevents water entering the space 22 in the sleeve containing the heating element 21. A metal bridge 28 attached to the heating element ensures continued heating of the rising pipe 8, whilst a temperature sensing element controls a switch which cuts off the heating system in case of excess temperature. A lid 3, having a window 10 for receiving a transparent action 9 of the rising and falling pipe, is attached to the sleeve 5 and secured by a clamping bow 17 over the filter funnel, and water container. The funnel, oval at its filling end, is sealed from the water container 2 by packing 15 and insulated therefrom by provision of the gap 27.
