IPC: F27B7/40
Filed: 1924-11-27
Abstract: 248,079. Vickers, Ltd., and Parker, L., D. Nov. 27, 1924. Rotary furnaces.-A rotary kiln has a recuperator rotating therewith formed of a double shell arranged in front of the burning zone and provided with inlet and outlet openings for the clinker and the air which pass in opposite directions through a circuitous path in the annular space. The walls of the recuperator may be made double to provide spaces in which an auxiliary supply of air to the kiln may be heated. The kiln A lined with firebrick B and supplied with combustible through a pipe C is extended past the burning zone C<1> to form the outer shell D of the recuperator to which is fixed by bolts d the inner shell D<1>. Longitudinal plates D<2>, D' between the shells form a number of pairs of compartments D<4>, D<5> communicating with each other at their rear ends, the compartments D<4> being open at the front for the entry of clinker while the compartments D' are closed at the front but have lateral holes d<5> for the escape of clinker and the entry of air. Lifting plates d' on the inner shell D<1> agitate the clinker, which then falls over the edge of the shell into the open end of the lowermost compartment D<4> and is carried by the helical plates d<x>, Fig. 4, therein to the rear end of the compartment whence in the continued rotation of the kiln it falls into the contiguous compartments D' and passes by gravity and the action of helical plates to the front end and out of the kiln through the hole d<5>. Meanwhile air has entered at the hole d<5>, passed rearwardly along the compartment D<5> and forwardly along the compartment D<4> and thence into the interior of the kiln through the open end of the compartment D<4>. This operation occurs in respect of all the pairs of compartments D<4>, D<5> as shown in Fig. 1, where the flow of the clinker is indicated by the doubleheaded arrows and the flow of the air by the single-headed arrows. The outer and inner walls of the compartments D<4>, D<5> are constituted by members D<6>, D' arranged to provide spaces between them and the walls D, D<1> these spaces communicating with each other at the rear, and with the interior of the kiln at the front so that air admitted to the spaces through holes d<6> passes to the kiln. The partition plates D<2>, D<3> are also made double, the spaces between them having cooling ribs d<2>, d<3>, Fig. 4, and communicating with the compartments D<4>, D<5> at the rear and with the interior of the kiln at the front so that some of the air passes through the spaces:

Patent GB-728245-A (GB)
Title: Improvements in vehicles including at least one gas turbine
IPC: F02C6/20
Filed: 1952-11-14
Abstract: 728,245. Gas turbine plant. SOC. D'ETUDES ET DE PARTICIPATIONS, EAU, GAZ, ELECTRICITE ENERGIE SOC. ANON. Nov. 14, 1952 [Nov. 17, 1951], No. 28840/52. Class 110 (3). [Also in Group XXXI] In a vehicle having at least one gas turbine connected through a variable change speed device with a transmission, the turbine has, in addition to the turbine wheels driving the vehicle in the forward direction, at least one brake wheel turbine, which exerts an opposing torque on the turbine shaft, to which power gases are supplied when the engine control member is moved to the idling position. A gas turbine power plant for a vehicle comprises a free-piston power gas generator 6 feeding a turbine 1. The turbine comprises one or several wheels 2 fed with gas through a conduit 4 for forward driving and a turbine wheel 18 which when supplied with gas through the conduit 20 applies to the turbine shaft 13 a torque opposed to that of the wheels 2. The supply to the turbine wheel 18 is controlled by a valve 21. The power output of the free piston gas generator is controlled by regulating the injection pump 8 through a rod 7 by a pedal 9. The pedal 9 is urged to the off position by a spring 10. A clearance 12 allows an initial displacement of the pedal 9 before the rod 7 is moved. The turbine 1 is connected through a reduction gear 14, a clutch 15 and a change-speed gear 16 to the transmission shaft 17. When it is desired to change gear, the pedal 9 is first released. This causes the abutment 22 on the link 11 to abut against the lever 24 attached to the valve 21 and brings the valve into the position shown. This allows gas to be supplied to the turbine wheel 18 which then retards the turbine 1. When the pedal 9 is depressed the spring 23 urges the valve into the position in which the valve 21 closes the conduit 20. A braking lever 27 attached to the steering column is connected through a rod 29, a bell-crank 30, a lost-motion connection 31 and a rod 32 with the lever 24. In the position of the lever 27 shown the lost motion connection allows the valve 21 to be operated as described above. If the lever 27 is depressed, the valve 21 is moved into the position in which it fully closes conduit 4 and fully opens conduit 20. A strong braking action is then exerted on the wheels of the vehicle. A stronger braking effect may be obtained by depressing the pedal 9 and supplying more power gas to the turbine. The lever 27 is operated when the vehicle is moving downhill. The braking turbine wheel 18 may be mounted on a shaft distinct from shaft 13 and be connected thereto through suitable means such as gears. The gases may be supplied by a compressor driven by the turbine which feeds combustion chambers between the turbine and compressor. During idling of the plant, the valve 21 is in the position shown in which gas is supplied to both the wheels 2 and the wheel 18 which are so arranged that the resultant torque on the transmission shaft 17 is negligible. Specification 685,943 is referred to.

Title: Improvements in automatic water softening apparatus
IPC: C02F1/42
Filed: 1922-10-24
Abstract: 206,684. Marks, E. C. R., (Wayne Tank & Pump Co.). Oct. 24, 1922. Valves actuated automatically and intermittently for water-softening apparatus. A valve 58, secured to a valve-rod 61, separates chambers 57, 59. The valve-rod is connected to a piston 64 working in a cylinder 67, which is provided with a seating for a check valve 69, and with ports 73 for the passage of water to a chamber 74. A housing 76, fitted with a tube 77, accommodates a ring slug 78, fitted with packing rings, and an annular recess to seat a poppet slug 82. The parts 78-82 constitute a piston, and when forced upwardly, they expel water through an opening in a pin 85 into a chamber 88, which is fitted with a weighted diaphragm 89. When the slug 82 seats on the pin 85, the pressures throughout the softening chambers equalize, the valve 58 opens by gravity and material passes from the chamber 57 into the chamber 59. Meanwhile water in the chamber 88 passes out through coils 94, 95 until a spring 101 carried by the diaphragm 89 unseats the slug 82, and reduces the pressure in the chamber 74, whereby the piston 64 rises, the valve 58 seats and the pressures in the chambers 57, 74 equalize. The apparatus is now ready to re-commence the cycle. The Specification also describes a valve for supplying measured quantities of brine similar to that described in Specification 206,683. Specification 208,576 also is referred to.

Abstract: 1301999 Projectile fuzes WERKZEUG MASCHINENFABRIK OERLIKENBUHRLE AG 22 June 1971 [26 June 1970] 29085/71 Heading F3A An impact fuze for a spin-stabilized projectile which can be set for direct and delayed action comprises a stud 36, Fig. 1, that sets back upon axial acceleration to enable a detonator pallet 22 to rotate into an armedposition under the action of a spring 29, lines extending from the centre of gravity S, Fig. 5, of the pallet through the axis of rotation D of the pallet and the spin axis A of the fuze defining an acute angle α, whereby the tangential component T 1  of the inertial force F 1  arising from the spin acceleration, opposes the thrust of spring 29 as well as the centrifugal force Z 1  acting on the pallet so that the contact pressure between the stud 36 and the pallet 22 is thus reduced, permitting the stud to set back reliably without jamming. Movement of the pallet into the armed position is delayed by means of an escapement mechanism co-operating with a toothed quadrant 38, Fig. 2, of the pallet. The pallet carries two detonators 56 and 66, Fig. 2, which in the armed position are respectively aligned with a striker 46, Fig. 4, beneath the pallet, and a striker 15 above the pallet. The striker 46, Fig. 4, is locked against the action of a spring 44 by balls 49. Axially displaceable sleeves 42 and 51 surround the striker. To set the fuze for direct action, a key 57, Fig. 1, is rotated so that the striker 15 is free to pass through an aperture 59. Upon firing, the striker 15 sets back into a recess 62 in the pallet, the pallet also sets back firmly against a face 13, and the stud 36 sets back to unlock the rotor. When the acceleration ceases, the striker vacates the recess 62, and the pallet moves forwards again under the action of spring 29 and subsequently rotates, with delay, into the armed position. At impact the striker 15 is driven into the corresponding detonator. To set the fuze for delay action, the key 57 is rotated so that the striker 15 cannot set back, Fig. la. Upon firing, the arming action is otherwise as before. At impact, the sleeves 42 and 51, Fig. 4, are thrown forwards, but the spring 44 returns the sleeve 42 to its original position and the balls 49 enter the gap created between the two sleeves, thus enabling the spring to drive the striker into the corresponding detonator 56. The flash from the detonator passes beneath the pallet to a relay.
