Title: Improvements in or relating to the construction of buildings
IPC: B28B23/06
Filed: 1950-03-16
Abstract: 695,869. Construction of buildings; floors, roofs. WILLIAMS, Sir E. O. March 16, 1951 [March 16, 1950], No. 6640/50. Class 20(iv) In a method of constructing buildings where -a large mobile load is required to be movable along a path across a floor or roof of external area which is unsupported near to the path except at a perimeter point or points the floor or roof has girderlike rigidity in the direction of the path and at least one perimeter point of the floor or roof lying near to the path is prestressed down-wardly and rigidly connected to the ground or equivalent foundation through a strut or column to maintainthe prestressed condition and also act as a rigid compression-resisting strut or column. In an application described, an airplane hangar has a roof 10 constructed in three sections 11; 12 and 13 each comprised of a series of inverted V-section main members 14 of reinforced concrete made in situ together with interconnecting transverse beams 15' at their upper and lower edges and a crane rail 20 for a mobile crane 21. The opposite ends of the two outer roof sections are supported upon arms 16 of pier members 17 which with beams 18 define arched doorways at both ends of the building. At the perimeter points 22 reinforced concrete columns 24 are formed rigid at their upper ends with the adjacent roof section 11 or 12 and supported at their lower ends on removable jacks or wedges. The weight of the columns is made more or less equal to the stress to be applied and the jacks or wedges are removed so that the columns are suspended from the points 22 of the roof. With the roof under such conditions of stress the lower ends of the columns are rigidly anchored to the ground, for example, by a concrete block 27.

Title: Inflatable panel for agitating material in a hopper
IPC: B65D88/62
Filed: 1965-02-16
Abstract: 1,073,891. Agitating material in hoppers. A. TZIRIPOULOFF. Feb. 16, 1965 [March 27, 1964], No. 6652/65. Heading B8S. The diaphragm 1 of a pneumatic device for agitating material within a hopper by repeated vibrations thereof is formed of three plies and is connected to inlet valve 4 by chains 18 and is provided with an outlet ball valve 5. Air enters at 39. Base-plate 3 is secured to the inside of the hopper. Fig. 4 (not shown).-Chains (18) are connected by rod (27) to closure (19) pivoted at (23). Diaphragm 2 (Fig. 2, not shown).-The diaphragm is formed of rubber layer (6), permeable fabric layer (7) and rubber layer (8); layers (6) and (7) being secured together between jaw members (12) and (13) and adjustably secured at (15) to said chains (18). The layer (7) serves to limit the expansion of layer (6). Jaw member (13) carries plug (34) which is seated within an aperture formed in outer layer (8) so that layer (8) may detach itself from layers (6) and (7) if air should leak through the latter layers. The diaphragm is thus adapted to avoid bursting. Operation.-Air from (39) enters at (38) to cause inflation of diaphragm (1) till the chains (18) operate to close the closure (19). When suction is applied at (39), air from diaphragm (1) is first released through outlet valve (5) and then released through closure (19). Fluctuation of the source of air (39) thus produces vibration of diaphragm to agitate material in the hopper.

Abstract: 633,861. Hydraulic presses. BURTON, L. J. March 10, 1947, No. 6659. [Class 69 (ii)] In a hydraulic press comprising a hydraulic piston and cylinder assembly mounted in a frame which consists of opposed metal sidewalls having an upper cross - wall spaced from the upper end thereof to form an upper compartment and an intermediate cross-wall spaced from the lower end thereof to form a lower compartment, the intermediate cross-wall constitutes a work table beneath the hydraulic piston and cylinder assembly which is mounted in the frame beneath the upper cross-wall and is independently guided by external guide-elements engaging guides on the inner faces of the opposed side-walls, which latter, together with the upper cross-wall are formed as a metal casting or fabricated by welding; the upper compartment may contain a hydraulic pump and liquid reservoir, and a press head displaceable by the pistons and cylinder may be adapted to co-operate with the intermediate cross-wall. The main frame is constituted by metal side-walls 1, Fig. 1, integral with a baseplate 2, whilst longitudinal partitions divide the space above the upper cross-wall 3 into three compartments, oil reservoir 6, pump housing 7 and a conduit chamber 8. A manually-controlled valve 11 provides for connecting either of two conduits 9 and 10, Fig. 4, which pass through chamber 8, to a pump 13 in the housing 7. Conduits 14 and 15 provide for communication between the reservoir 6 and the valve 11 and pump 13 respectively. The conduit 10, which includes a pre-filling valve 17 fed from the reservoir 6, opens into the interior of a hollow piston 16 fixed to the crosswall 3 and when it is connected to the pump 13 causes the press to extend. The conduit 9 passes through the wall of the piston 16 and opens into an annular space between the latter and a cylinder 18, Fig. 1, reciprocable upon the guide elements over most of the axial length of the piston 16, thereby enabling the press to be retracted. The press head is fitted to the underside of the cylinder to co-operate, in the extended position, with a mould 26 positioned upon the intermediate cross-wall 27. The space beneath wall 27 is stated to be used for housing an ejector cylinder or mechanically-operated ejector-gear. The housing 7 may also contain a motor for driving the pump 13.

Title: Improvements relating to controlling the supply of gas to the burners of water boilers or the like
IPC: A47J31/56
Filed: 1953-03-12
Abstract: 726,845. Controlling gas burners. JACKSON BOILERS. Ltd., and MUSTILL, C. W. March 12, 1953, No. 6788/53. Class 75 (1). [Also in Group XXIX] Gas is supplied to the burner 2 of a water boiler through a main gas valve 5 mechanically connected to the main draw-off tap 3 of the boiler, and through a' diaphragm-operated gas valve 7 placed in parallel with the main gas valve 5. The operation of the diaphragm-operated valve 7 is effected by one or more gas valves 8, 9 each connected in series by a pipe 10 with a chamber on one side of the diaphragm of the valve 7. The valves 8, 9 are arranged in parallel to one another and the pipe 10 has an open end 11 near the b'urner 2. If any of the valves 8, 9 is open, gas flows through the pipe 10 and reduces the pressure on one side of the diaphragm, which moves to open the gas valve 7. The valves 8 are mechanically connected to side draw-off taps of the boiler, and the valve 9 is thermostatically actuated. The valves 5, 7 may be separate units arranged on opposite sides of the boiler, or as in Fig. 4, may be included in a single unit. In this, the main gas valve is a hollow plug 28 with inlet 33 and outlet 34, and an open end. When the hollow plug 28 closes the inlet port 35, a valve 31 carried by a diaphragm 30 controls the gas flow through the open end of the plug to the outlet 36. When the valves 8, 9 are closed, gas leaks through the passage 42 into the chamber 41 until the pressures on both sides of the diaphragm are equalized A spring 40 urges the diaphragm valve 31 towards its closed position, this movement being limited by the slidable engagement of a collar 37a on the diaphragm with an adjustable stud 37. When one of the valves 8, 9 opens, the pressure in the chamber 41 is reduced and the valve 31 opens. In a modification the valve 31 is above the plug 28. and is urged to close by gravity; the spring 40 is omitted.

Title: Improvements in or relating to control lever mechanism
IPC: B64D31/04
Filed: 1947-03-12
Abstract: 622,339. Controlling aircraft. NAPIER & SON, Ltd., D., and SNELL, L. S. March 12, 1947, No. 6862. [Class 4] [Also in Group XXIV] A control lever mechanism particularly for use on aircraft comprises a lever E with interchangeable fulcrums G, J for actuating a control rod A, A<SP>1</SP> so that continued operation of the lever in one direction will first move the rod A, A<SP>1</SP> in one direction and then the other. The lever works in a gate C<SP>1</SP> provided with longitudinal slots D, D<SP>1</SP>, D<SP>3</SP> and a transverse slot D<SP>2</SP>. The transverse movement in slot D<SP>2</SP> moves rollers G<SP>1</SP>, J<SP>1</SP> on the fulcrum pins G, J into and out of sockets H and K on the supporting casing C, this transverse movement being allowed by slight rotation of the rod A, A<SP>1</SP> to which the lever E is pivotally connected at F. Thus, movement of the lever along slot D in a clockwise direction in Fig. 1, with the fulcrum J engaged, will move rod A, A<SP>1</SP> to the left, transverse movement in slot D<SP>2</SP> will disengage fulcrum J and engage fulcrum G and continued clockwise movement along slot D<SP>3</SP> will then move rod A, A<SP>1</SP> to the right. In an aircraft control, this lever mechanism is utilized to control the engine throttle in conjunction with a reversible pitch propeller used for braking. The first movement in slot D closes the throttle to decrease the engine speed, the transverse movement in slot D<SP>2</SP> effects, through a cam L on rod A, A<SP>1</SP> operating a switch or valve M<SP>1</SP>, a reversal of the propeller pitch, and the further movement in slot D<SP>3</SP> opens the throttle again to speed up the engine and propeller for braking. The slot D<SP>1</SP> is provided so that the lever E may be moved if desired to completely close the engine throttle and to shut off a fuel supply cock. This control of the throttle and fuel cock may be effected as shown in Fig. 5 by an intermittent toothed rack N connected to the rod A, A<SP>1</SP> engaging teeth Q<SP>2</SP> and P<SP>2</SP> on levers Q, P operating throttle and fuel cock rods Q', P<SP>4</SP> respectively. The arrangement is such that during movement of lever E in slot D the rack N engages throttle operating lever Q only whilst on movement into slot D<SP>1</SP> the lever P only is engaged to close the fuel cock. An interconnection may be provided in the circuit of the valve or switch Ml with the operating mechanism of the aircraft under-carriage so that the pitch of the propeller cannot be reversed for braking until the under-carriage has been lowered. Alternatively, a locking detent may be provided on the cam L to prevent its rotation, and the transverse movement of lever E in the slot D<SP>2</SP>, until the under-carriage has been lowered.
