Title: Improvements in and relating to aircraft having vertically reciprocating planes
IPC: B64C33/02
Filed: 1920-05-05
Abstract: 146,088. Florence, A. July 3, 1919, [Convention date]. Aerial machines without aerostats; planes, construction and arrangement of; propelling. - An aerial vehicle has the main plane a formed with series of pivoted slats and arranged to be reciprocated vertically to give a lifting effect. The plane is supported by four struts b upon a chassis c mounted on springs d and connected by rods k to a crank-shaft g. The slats turn on longitudinal axes and, during the up-stroke, hang at an angle of about 45 degrees. When the machine is in use as an aeroplane, the slats are moved by cords to the horizontal position to form a continuous surface. The central quadrangular portion a' of the plane is raised above the remainder, and the wing- tips a<4>, a<5>, instead of being formed as slats, may be hinged at p, so that they may be let down by cords for the vertical flight, and held horizontal for the horizontal or gliding flight. Lateral struts q, resting on springs s and brackets r, may be provided for the parts a<2>, a' of the plane. The reciprocating mechanism may be held locked by a bolt u. The cranks on the shaft g may be replaced by elliptic wheels or cams engaging wheels on the chassis c, the latter wheels and the eccentric parts of the elliptic wheels being toothed if desired. A biplane arrangement may be used, only one of the planes having a raised part a<1>; in the case where the lower planes are at the sides of the body. these planes are provided with slats but not reciprocated. In large aeroplanes, the usual planes may be formed with slats but not reciprocated, an additional reciprocating plane being provided behind the main planes. One or more lifting-screws may be provided, one of them being placed below the body, and the usual propellers are provided for horizontal flight. Aerial machines with aerostats.-Fig. 7 shows a machine of this type having the reciprocating plane a mounted on the gas-envelope 1 and a lifting-screw 2 below. The plane a extends in the longitudinal direction of the air-ship. Steering may be effected by two or more propellers or pairs of propellers, such as those shown at 3 in connexion with the air-ship, Fig. 7, arranged on transverse axes at the front and rear and provided with reversing-gear. These propellers may be arranged so that their shafts may be moved into a longitudinal direction for driving, or into a vertical direction for lifting. The pivoted slats of the planes may be simultaneously set horizontally for horizontal flight, or be inclined for descending. Cars and cabins.-In the air-chip, Fig. 7, a gangway may be constructed over or beside the plane a to facilitate communication.

Title: Improvements in mine shaft hoisting installations
IPC: B66B5/14
Filed: 1959-04-13
Abstract: 914,432. Tensiometers. GUTEHOFFNUNGSHUTTE STERKRADE A.G. April 13, 1959 [April 12, 1958], No. 12531/59. Class 40 (1). [Also in Group XIX] The tension in the hoisting rope of a mine shaft is measured in terms of the force applied to a deflecting pulley or the amount of deflection produced thereby. In Fig. 1 the rope 1 bears against a pulley 3 which is mounted on a bellcrank 4 which can pivot about a point 5. To the other end of the bell-crank is attached a cylindrical ferromagnetic body 7 whose permeability is changed when the force on it varies, and this alters the current in a coil 8. The current can be measured by an instrument calibrated directly in tension, and can be recorded on a strip. If the tension exceeds a certain amount a signal can be given. In a modification (Fig. 3, not shown), a similar device is fitted to a second strand of the rope, and a plurality of such devices can be used in multi-rope hoisting installations to compare the loads on the individual ropes. In a further modification (not shown) the pulley can be deflected against a spring.

Abstract: 1435059 Telegraphy; isolating devices; photo isolating circuits ITT CREED Ltd 21 March 1974 12539/74 Heading H3T An arrangement for electrically isolating telegraph apparatus, from a line, line signals are fed through a subtractor to a first isolating non- linear coupler providing an input to a high gain amplifier driving in turn a second coupler the output from which source is applied to the subtractor. The amplifier gain is arranged so that output current is substantially linearly related to line current. In a block diagram (Fig. 1, not shown) line currents are led through subtractor (2) and through square root circuit (4) to amplifier (5) supplying current to utilizing device (6), i.e. tape punch, teleprinter &c. and thence through another square root circuit (3) similar to (4) to a second input of subtracter (2). In a practical arrangement line currents pass through a resistor RT, considered as a subtractor, to light emitting element DF forming part of coupler 4, together with sensitive element PF supplied from source 7 and controlling amplifier 5 which feeds device 6 and thence to a second light emitting element 3 forming with sensitive element PB the second non-linear coupler, output from which is fed back to input point J.  In this arrangement line current supplies power for operating DF, PB but in an alternative arrangement (Fig. 3, not shown) a separate isolated supply (9) is led to DP through transistor (8) amplifying line current. Supply (9) may be of any type, e.g. transformer/rectifier, battery, or set of photo voltaic cells.

Title: Fuel injection system for internal combustion engines
IPC: F02M57/02
Filed: 1940-08-03
Abstract: 550,476. Fuel-injection pumps. BELL, G. A. Aug. 3, 1940, No. 12547. Convention date, Aug. 4, 1939. [Class 102 (i)] [Also in Group XXVII] A fuel-injection pump for internal combustion engines comprises a plunger 14 which is reciprocated and oscillated within a highpressure chamber 10, and which, during its inward movement first engages a valve disc 16 to close a bore in the plunger feeding fuel to the chamber, then opens an injection valve 34, and finally unseats the valve disc and closes the injection valve. The plunger 14 is fitted with an enlarged collar 26 which reciprocates in a low-pressure chamber 9 and is connected by inclined links 29 and pivots 30, 31 to a fixed collar 28, the plunger being connected by a twopiece spline 27 to an oscillating shaft 17. The latter terminates in a disc 20 with a port 21 to register with a port 22 supplying low-pressure fuel through a non-return valve 24. The valve disc 16 has one extension 32 in splined connection with the plunger 14, and another extension 37 screw-threaded at 38 into an extension 35 of the injection valve 34. Substa,ntial rotation of the extension 35 is prevented, and its upward movement limited, by providing it with teeth 40 which engage slots 41 formed in a screwthreaded sleeve 42 adjustably secured in position by a lock 43. A shoulder 45 on the injection valve 34 is held against a shoulder 44 on the extension 35 by a spring 47 and a bar 46 engaged in slots 48 in this extension. The conical lower end 34a of the injection valve engages a conical seat 51 which is slightly relieved at 52 and provided with orifices 53 which may be drilled horizontally or normally to the surface of the seat 51. The enlarged upper end 55 of the valve 34 is a close fit in an enlarged shoulder 57 of the tip 49, which shoulder is slotted at 59, and fuel passes through these slots, a filter 61, apertures 60 in the tip 49, and around the lower end of the valve to the orifices 53. The inclined links 29 cause an inward movement of the plunger such that its helical pitch is at a maximum at the beginning and at a minimum at the end of its stroke, whilst the helical pitch of the threads 38 is intermediate these maximum and minimum pitches. When the plunger 14 first begins to move it approaches the valve disc 16 faster than the extension 37 screws into the extension 35, and the plunger therefore engages and slightly depresses the valve disc. Continued descent of the plunger at a slower rate then allows the threads 38 to lift the valve 34, the valve disc 16 being held against the plunger 14 by the high pressure in the chamber 10 if sufficient fuel has been fed to the injector through the port 22. If this pressure is insufficient, the valve 34 is seated by the spring 47 breaking the connection between the valve disc and the plunger, and the pressure in the chamber 10 is relieved to prevent drip. When the teeth 40 strike the upper ends of the slots 41 the seal between the valve disc and the plunger is broken.

A regulating device for maintaining the speed of a hydraulic motor, reciprocating or rotary, at a predetermined value comprises a member responsive to variations in the motor outlet pressure from a predetermined datum value to regulate a servomotor actuating means .controlling the quantity of liquid supplied. to the motor. As shown, the outlet pipe 3, Fig. 1, from a hydraulic motor M has an adjustable throttle member 4 to maintain a datum pressure in the pipe 3. A spring-loaded piston valve 11 responsive at one end to variations in this datum pressure controls the supply and exhaust of pressure liquid to and from opposite sides of the vane 14a of a servomotor 14. Liquid is supplied to the servomotor through a branch 15 from a line 2 connecting the motor M and a pump P and exhausted through a branch 16 having a throttle member 17 to prevent over-regulation of the servomotor. To control the supply of liquid to the motor M, the vane 14a may control a rheostat connected in series with the shunt winding of an electric motor driving the pump P to control the speed of the electric motor. In another embodiment, the motor outlet pipe 3, Fig. 2, having an adjustable throttle 4 is connected by a branch 5 to a Bourdon tube 18 which through a rod 19 deflects a jet tube 20 continuously fed with pressure liquid from a branch 15 from the line 2 to move a piston in a servomotor 21 in either direction from its central neutral position. The servomotor 14 or the servomotor 21 may alter the position of a throttle valve in the line 2 or in a pump supply line 1, change the operating speed of an induction motor driving the pump, the ratio of a gear-box between the motor and pump or the opening of a by-pass valve in the line 2, to regulate the amount of liquid supplied to the motor M.
