Title: Improvements in reversing mechanism for toothed gearings, particularly for use in connection with turbines
IPC: F01D15/02
Filed: 1924-03-29
Abstract: 213,609. Aktiebolaget Ljungstr÷ms Angturbin. March 31, 1923, [Convention date]. Reversing gearing.-In a reversing mechanism of the kind wherein a shaft 9 carrying a pinion 10 meshing with a gear-wheel 11 is mounted in an eccentric which is rotatable by fluid-pressure acting on a piston in a cylinder 16, so as to effect reverse running of the gear 11 through the displacement of the shaft 9 and the introduction of another gear shaft 17 into the train, the shaft 9 is axially aligned with the shaft 6 driven by the turbines 1, 2, and is flexibly connected thereto by diaphragm couplings permitting the lateral displacement of the shaft 9. The connection between the shafts 6, 9 is made by a shaft 21 extending through the hollow shaft 9 and connected at the right-hand end with the shaft 6 by means of a diaphragm coupling 22, and at the left-hand end with the shaft 9 by means of a diaphragm coupling 23. The low-pressure turbine 3 has its shaft 30 flexibly connected to a laterally displaceable shaft 31 by a shaft and couplings disposed wholly at one side of the shaft 31. The shaft 17 may be mounted so as to be laterally movable like the shaft 9, or it may be mounted in stationary bearings and have its gears in constant mesh with the gear 11. Brakes are put into action before reversing, and an auxiliary oil-actuated turbine 24 is provided to rotate the pinion shaft 9 to facilitate the engagement of the teeth. The oil-supply for this auxiliary turbine flows first through a cylinder 26 to force a piston inwards so as to throw in a coupling 25 between the turbine shaft 27 and the shaft 9.

Title: Improvements in or relating to hand presses
IPC: B30B1/02
Filed: 1948-03-19
Abstract: 641,840. Mechanical presses. ROGERS, H. W. March 19, 1948, No. 8187. [Class 87 (ii)] A hand-operated press wherein a hand lever initiates the closing and opening movements through a toggle mechanism, has a fluid operable cylinder and piston, controlled by means adapted to be brought into operation automatically when the hand lever reaches a predetermined position in order to assist the press movements by power. The hand lever d pivoted on a shaft d<SP>1</SP>, Fig. 1, on being moved downwardly by the operator to the position shown in full lines, actuates the toggle mechanism e, f, a rocking lever g pivoted at h in the main supporting frame a, and an adjustable link j secured at its lower end by a ball-andsocket joint k to head c to press the head on work placed on a vertically adjustable table b. To increase the mechanical pressure a piston p working within a cylinder o pivoted at q, is adapted to apply direct force to toggle pin r, the fluid pressure to the piston being controlled, via supply and exhaust piping v<SP>1</SP> and v<SP>2</SP> respectively, by a valve v having a spring-loaded adjustable valve spindle or plunger w operated by an adjustable stop u attached to the bearing boss of the lever d. The valve plunger may, however, be actuated independently of lever d by means of a release lever x (Fig. 2, not shown). The head c and associated linkage are balanced by an adjustable weight l slidablo on an extension m<SP>1</SP> of the boss of a sector plate m secured to shaft d<SP>1</SP>. The sector m receives pressure from lever d through a pin n secured thereto and able to slide in a slot m<SP>2</SP> of sector m, thus providing a degree of lost motion. The pressure on head c may be maintained for any period of time, being released by reverse movement of lever d, or if necessary by admitting fluid pressure to the toggle end of cylinder o. In a modification the action of the toggle links may be reversed, cylinder o and piston p being to the left (as viewed in Fig. 1), of the press. In this arrangement the lever d is moved upwardly in order to apply pressure to head c.

Title: Improvements in or relating to permutation switches
IPC: G09C1/12
Filed: 1961-03-07
Abstract: 957,734. Electric switches. ANSTALT EUROPAISCHE HANDELSGESELLSCHAFT. March 7, 1961 [March 8, 1960], No. 8270/61. Heading H2B. [Also in Division G5]. In a permutation switch, particularly for coding and decoding apparatus, having a number of rotors 3, 4, 5 mounted on a common shaft and provided on their sides facing one another with wiping contacts 10, 11 for passing on information from one rotor to the next, relative step-by-step angular movement of one rotor in relation to another causes axial separation of the rotors so as to reduce the contact pressure of the contacts during such movement and lessen soiling and wear of the contacts. In the form illustrated, adjacent surfaces of the rotors have interengaging serrations 9, and such serrations on the outer sides of the end rotors 3, 5 engage serrations on two members 6, 7 axially movable but not rotatable on the shaft 2. Springs 8 press the assembly together, so that when rotary movement of a rotor occurs, the serrations 9 cause the rotor to move axially relatively to adjacent rotors so as temporarily reduce the pressure between the contacts. Other means for causing axial separation of rotors, such as balls engageable and disengageable with recesses in adjacent rotors or means operating electrically, pneumatically or hydraulically, may be employed. Each rotor carries a toothed wheel 12 by which it may be rotated from a control device 15 as, for example, is described in Specification 319,438.

Title: Improvements in or relating to automatic safety cut-out for the control mechanism ofadjustable surfaces subject to fluid pressure
IPC: G05D1/00
Filed: 1949-03-29
Abstract: 719,691. Fluid-pressure servomotor-control systems. SHIELDS, F. J., FENN, A. E., BARBER, E. G., and MUNDAY, F. J. March 29, 1950 [March 29, 1949], No. 8437/49 Class 135. [Also in Group XXXV]  In a servomotor system for adjusting control surfaces subject to fluid pressure on an aircraft or a ship, a predetermined or excess load in the system between the power source and the control surface, which load results from fluid pressure loading on the surface, actuates a cut-out to relieve the system between the power source and the control surface of all load. In an embodiment, the differential pressures acting on the two sides of a piston operating motor in a pneumatic control system are also applied to two bellows 17, 18, Fig. 2, which act on the opposite ends of a lever pivoted at its mid-point, and on which a further lever rests. On the occurrence of an excessive pressure difference across the piston, the bellows will tilt the two levers and the upper one will break the contacts of a micro-switch 22, Figs. 2 and 4. This will cut off current through a solenoid 23, releasing the armature thereof, so closing a valve 26 and cutting off the air supply to the control system. At the same time, the loading springs 51 of the solenoid armature will open a contact 27 and close a contact 28 so reversing red and green indicator lights. The main cock controlling the supply of compressed air, is operated in two stages : in the first, the air supply for rotating an attitude detecting gyroscope is switched on, and in the second, the'air supply to the control system is switched as far as valve 26 and a switch 32 controlling the electric supply is made. A press button switch 29 is now actuated and the circuit will be set for normal operation with solenoid 23 energized and valve 26 opened. When the operating motor is electrically energized the cut-out is actuated by the potential drop across the motor. Alternatively, where the rate change of displacement of a gimbal ring of the gyroscope is converted to an electrical signal which is applied to an amplifier controlling the electric operating motor and a feed back to the amplifier is effected by means controlled by the motor the cut-out is operated by means responsive to a predetermined difference between the electrical signal from the gyroscope and the feed back.

Abstract: 526,501. Valve relays. ASSOCIATED ELECTRIC LABORATORIES, Inc. March 17, 1939, No. 8636. Convention date, March 19, 1938. [Class 40 (v)] An impulse responding circuit includes a relay in the anode circuit of a valve so biased about the lower bend of the anode current grid voltage characteristic that the relay winding normally carries current but means are provided to ensure its release when no alternating current impulses are being received. The received signals are repeated by a relay energized by a condenser discharge so that the repeated signals are of constant duration. The relay 22 is normally held in the de-energized condition by current flowing from +B over 23, 22 and 28 to -B. When a signal is received current also flows in opposition to this from +B through valve 15, relay 22 and 26 to -B and the armature 29 moves to make contact 31. Condenser 32, which has been charging over 35, 36, is discharged through relay 14 and this relay energizes to close contacts 13 and repeat the signal over 12. The impedance of relay 14 and the capacities of condensers 32 and 38 are adjusted so that relay 14 remains energized for the same time interval no matter for how long the relay 22 is energized.
