Title: Improvements in air craft
IPC: B64B1/62
Filed: 1919-08-14
Abstract: 153,950. Chaddock, G. A. Aug. 14, 1919. Airships; aerostats; cars and cabins; tanks and like containers, arrangement and disposition of; signals and indicators, applications of.-An airship comprises in combination propellers carried along the sides of the ship by outrigger frames provided with front and side screens, lift planes above the propellers, a watertight main hull with watertight side extensions carrying all the load, means for utilising the waste engine heat, together with means for admitting cool air for controlling the gas bag lift, and means for using the main gas as fuel. The propellers and engines may be rotated to give a direct lift or combined lift and drive. The hull 1, Fig. 4, has a watertight outer sheathing with circular bottom 2, which reduces suction when the ship rises from water. Side flat-bottomed structures 3 increase resistance to descent and prevent dangerous lists when floating, these side structures carry the engines 10, cabins 22, and other dead weight. The sides, bottom, and decks of the hull may have an inner and outer flooring, and may be formed with tanks for fuel, oil and water. They may be constructed to break up sound waves externally and internally. Air ports 4, 5 are controlled so that cold air may be admitted to the hull to cool the gas bags. The engine exhaust may be led to expansion boxes in the main hull, in order to reduce noise and to heat the gas bags, before being led outboard. In addition to this control of the buoyancy, auxiliary gas containers 6, Fig. 2, are coupled by valvecontrolled connexions to the main gas bags and to the engines, whereby the gas in the main bags may be increased or diminished, and gas may be used as engine fuel. A depending wire or cable is fitted as a lightning conductor; this wire, according to one of the Provisional Specifications, may be connected to devices for indicating speed or distance travelled or drift over water. According to the Provisional Specifications, the bow and stern extension planes may be constructed to contain gas which can be used for cooking or other purposes. Propelling; steering.-The outer portion of the side structure is made up of a braced framework 16, 18 together with supports 14 for the propellers 7, which are distributed along the hull on either side. The propellers and engines may be turned by rack and quadrant gear from a position giving direct lift to positions giving combined lift and drive. The propellers are placed in swells or casings formed by planes 19, forward screens 17 and side screens 18, the planes 19 being at an angle to give sustentation when the ship is in horizontal flight. Extension planes 19<a>, Fig. 1, are provided at the stern. A ridge wire connects the extensions 19<c> of the propeller supports with the framework, and a stay rope 24 connects the screens 17 on the two sides. Vertical rudders 25 and horizontal rudders are fitted at the bow. The exhaust from the motors may be led to silencers in the main hull.

Title: Improvements in and relating to hand driven computing machines
Filed: 1949-07-29
Abstract: 662,118. Calculating-apparatus. OLIVETTI & C. SOC. p A., ING. C. July 29, 1949 [Aug. 31, 1948], No. 20027/49. Class 106 (i). A hand-driven computing-machine comprises the combination of a single function-setting means, a Cardan type joint connected thereto and permitting said function-setting means to be set from an inactive position into more than two active positions, and a plurality of machinefunction control means associated with said joint, whereby in response to the setting of said single function-setting means into any one of its active positions a single machine-function control means is selectively set. A key 1, Figs. 2, 3, 5, 6, normally positioned at the centre of a cruciform window 3, Fig. 2, has a stem 2 by means of which it is attached to a bail 4, Figs. 3, 5, 6, oscillatable about the axis of a shaft 5, 51 carried by a second bail 6 oscillatable about the axis of a shaft 7, 7<SP>1</SP> supported on a frame T at right angles to the shaft 5, 5<SP>1</SP>. The key 1 is thus movable to any of the four positions shown in Fig. 2. The bail 4, Figs. 3, 5 is connected. by a lever 8 and a pin-and-slot 9, 101 to a lever 10 fixed to a shaft 11 carrying a double-armed lever 15 having pins 16<SP>1</SP>, 17<SP>1</SP> which engage slots 16<SP>11</SP>, 17<SP>11</SP> in function-control members 16, 17, respectively urged upwards by springs 22, 23. The bail 6, Figs. 3, 6, carries a lever 12 having a pin 13 which engages a slot 14<SP>1</SP> in a lever 14 loose on the shaft 11 and connected to a doublearmed lever 19 having pins 201, 211 which engage slots 20<SP>11</SP>, 21<SP>11</SP> in function-control members 20, 21 respectively. The arrangement is such that movement of the key 1 forward or backward, Fig. 2, results in depression of the member 17 or 16, respectively, and movement of the key to the left or right results in depression of the member 20 or 21, respectively. Upon rocking of the operating handle (not shown), after the key 1 has been set, the main shaft 38, Fig. 5, rocks clockwise to free a lever 34 which is rocked clockwise by a spring 36, a pin 39 on the lever 34 abuts a pivoted lever 32 which is thereupon carried clockwise and a bail 28 attached to an arm 29 connected to the lever 32 engages the bottom end of the extensions 26, 27 of the levers 10 and 14, respectively, which levers and the key 1 are thereby locked in the positions to which they had been set. In the return anticlockwise movement of the shaft 38 a pin 37 on a lever 37<SP>1</SP> returns the lever 34 and thereby the lever 32 and arm 29 to their initial positions so unlocking the key 1. The key 1 can be unlocked at any time after setting by manual movement of an extension 35 of the lever 32.

Title: Method of and apparatus for continuously producing small section welded steel tubes
IPC: B21B17/14
Filed: 1959-06-12
Abstract: 913,063. Making tubes; bending; rolling; welding. BENTELER-WERKE A.G. June 12, 1959 [June 13, 1958], No. 20152/59. Classes 83 (2) and 83 (4). In a method of continuously producing small-section, e.g. 20-3 mm. diameter welded steel tubes a strip is drawn through a plurality of freely-rotating undriven bending roll sets 6a, 6b, 6c to form a slotted tube, the slot in the tube is welded to form a longitudinal seam and the tube is then passed through guide rolls 16a 16b, 16c, 16d to prevent twist and to slightly deform the tube prior to cold-reduction in a mill which supplies the traction for the previous operations, the reducing mill comprising pairs of rolls 3a, 3b, 3c with oval-shaped passes arranged alternately at relative angles of 90 degrees and a final pair of rolls 3d with a circularshaped pass, the relative speeds of the roll pairs in the reduction mill being such that the material of the tube is stressed beyond its yield point. A steel suitable for deep-drawing is fed from a reel 2, by the traction of the reduction mill, through an edge-trimming cutter 5 prior to skelping. Adjustable closing rolls 7 are provided in advance of the welding point together with a sword 10 (Fig. 3, not shown), for correct alignment of the slot for welding. Pressure rolls 8 are provided at the welding point and welding is effected either by the argon arc process using a tungsten electrode 12 or by a resistance butt-welding process. In the latter case a bead-removing tool may be fitted to the bracket 9 carrying the sword 10. The guide rolls 16a, 16b, 16c have passes with alternately circular and oval grooves. Various diameters of finished tube may be produced from a skelp of the same width merely by removing an appropriate number of intermediate stands from the reducing mill. A traversable saw 18 cuts up the tube issuing from the mill.

Title: Improvements in or relating to servo systems
IPC: G05D1/06
Filed: 1951-08-29
Abstract: 724,518. Automatic control systems. SEDGFIELD, H. B., and SPERRY GYROSCOPE CO., Ltd. Aug. 20, 1952 [Aug. 29, 1951], No. 20383/51. Class 38 (4). In a servo system of the kind which normally operates to reduce the difference between a variable quantity and a reference quantity by controlling the former, but is also capable of inverted operation to reduce the difference by controlling the reference quantity, a time function of the reference quantity is introduced during inverted operation only. As applied to pitch control of an aircraft, a gyro vertical (not shown) controls a potentiometer P2 which together with a potentiometer P4 forms a bridge network the output of which is applied to the input terminals 11, 12 of a drift-stabilized D.C. amplifier 1, the output from terminals 13, 14 of which normally controls the energization of an electromagnetic clutch 20 associated with a reversible output shaft 6. A potentiometer P1 manually controlled by the pilot also supplies a D.C. signal to amplifier 1 and a resultant signal causes shaft 6 to operate a hydraulic control valve 22 so that a hydraulic servomotor 23 operates aircraft elevators 17 until the pitch of the aircraft corresponds to the setting of the pilot's potentiometer P1. Feedback to the amplifier input is provided by potentiometers P3, P5 associated with the control valve and elevators respectively. Resistance-capacity networks associated with the inputs to amplifier 1 introduce stabilizing rate components. If direct manual control is desired, automatic control of pitch may be eliminated by closing a switch 24 to energize a relay B, contact B4 of which changes over from the position shown to disconnect the output of amplifier 1 from clutch 20 and connect it instead to a transductor amplifier 19 controlling a two-phase servomotor 3 which thus maintains the pilot's potentiometer P1 in a position corresponding to the pitch so that automatic control may be re-engaged without shock. A contact B1 operated by relay B introduces a resistance-capacity network to stabilize operation in this manner and contact B2 introduces negative feedback to amplifier 1 to replace that no longer provided by potentiometer P3. Disconnection of other portions of the circuit not required during manual control by other contacts of relay B is referred to. Use of a hydraulic servomotor instead of the twophase servomotor is referred to. Specifications 666,882, [Group XL (c)], 690,982, 718,171 and 724,516 are referred to.

Title: Improvements in or relating to radio beacons
IPC: G01S1/02
Filed: 1946-07-08
Abstract: 630,250. Radio navigation. SOC. FRANCAISE RADIO-ELECTRIQUE. July 8, 1946, No. 20393. Convention date, June 30, 1942. [Class 40 (vii)] Relates to radio navigational systems for determining at a mobile receiver the bearing of the receiver with respect to a beacon in which the R.F. phase of the radiation emitted by the beacon is a function of azimuth, means being provided at the receiver for comparing the phase of the received R.F. signal with a datum signal also radiated by the beacon. As described the beacon comprises a plurality (n) of vertical aerials equally spaced round a circle and energized by radio-frequency currents of the same frequency and amplitude, the currents in adjacent aerials being dephased by 2#/n. In order to provide a datum signal having a phase substantially independent of azimuth the energy applied to each aerial is modulated at constant phase at a sub-harmonic of the radio frequency and at the mobile receiver the signal obtained by demodulation is frequency multiplied to equal the carrier frequency and compared in phase with the received carrier by means of a cathode-ray tube, the two signals being applied to the deflection plates to produce a radial line having an angular position indicative of the phase. In a modification the received modulated signal is heterodyned. to a higher frequency before demodulation. Several stations operating on. adjacent frequencies may be provided to serve a given area.

Title: Improvements in or relating to blow and squeeze moulding machines
IPC: B22C15/28
Filed: 1958-06-25
Abstract: 847,886. Moulding-machines. OSBORN MANUFACTURING CO. June 25, 1958 [July 18, 1957], No. 20411/58. Class 83 (1). A moulding-machine comprises means 5 for blowing sand into a box 17 in one position, and means for squeezing the mould in a second position while the mould is embraced by a flask 38. In operation, a slide 8 is moved by a ram 23 to position a mould-box 17 and a sand-reservoir 9 beneath a blowing-valve 5. A pattern-table 30 is raised against the mould-box and the blowing-valve operated. The table 30 is lowered and the ram 23 actuated, to move over the mould a flask 38 supported by a squeezing- head 37. The table 30 is again raised, the flask being located by pins on the table engaging lugs on the flask. When the mould has been squeezed, the table is lowered, leaving the mould in the flask 38. The ram 23 is again actuated to move the flask to a position where it can be slid from rollers 40, and to reposition the sand reservoir 9 which has been filled from a hopper 6. Empty flasks are delivered to the machine by a conveyer 54 and are picked up one at a time by a fluid-pressure-operated ram 58 carrying flaskengaging rollers 61 moved into gripping position by levers operated by a ram. A similar ram arrangement 65 lowers filled flasks on to a conveyer 68. A fluid-pressure-operated ram 71 then simultaneously moves an empty flask on to the rollers 40, and removes a filled flask to the lowering-head. The moulds may have gates and sprues such that a stack of moulds may be poured from a common gate. Specification 787,005 is referred to.
