Title: Acid producing plant
IPC: C01B32/50
Filed: 1956-08-08
Abstract: <PICT:0822825/III/1> In a plant for making acid by absorbing in water a gaseous oxide produced by oxidizing in a combustion chamber a suitable substance, such as ammonia, with compressed air, the air compressor is driven by a gas turbine and a steam turbine.  The former is operated by the tail gas from the absorber after it has undergone heat exchange with the combustion chamber.  The steam turbine is supplied from a boiler heated by the combustion, and the exhaust steam is condensed and returned to the boiler via an economizer heated by the gases leaving the combustion chamber.  In the illustrated embodiment for the production of nitric acid air is compressed by the low-pressure compressor 1 and high-pressure compressor 2 driven by the gas turbine 9 and the steam turbine 10. Ammonia is vaporized in the vaporizer-intercooler 8, and both the air and ammonia are led to the combustion chamber 7, where in the presence of platinum catalyst 12 they react to give nitric oxide and nitrogen dioxide.  The products flow through the economizer 14 and are absorbed in the tower 16.  The tail gas flows through 18 into the heat exchanger 19 and then drives the gas turbine 9. In the combustion chamber is a boiler consisting of primary and secondary evaporators 23 and 24.  The steam generated operates the steam turbine 10 and then flows through the condenser 26 and economizer 14 back to the boiler in the combustion chamber. Surplus energy may be utilized to drive a dynamo 29.  Other acids, such as sulphuric, phosphoric, and carbonic acids may be similarly made in this plant.

Title: Improvements relating to railway point operating mechanism
IPC: B61L5/10
Filed: 1933-09-01
Abstract: 424,844. Operating railway points. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Bone, H. L. ; c/o Union Switch & Signal Co., Swissvale, Pennsylvania, U.S.A.) Sept. 1, 1933, No. 24292. Convention date, Jan. 16. Addition to 421,731. [Class 104 (i)] In point-operating mechanism as described in the main application, comprising a circuit controller having point-detector contacts 84, 85 operated by the movement of the points from their normal position, means are provided for automatically retaining the contacts in their operated position in the event of the pointlocking mechanism failing to operate in the normal manner while a train &c. is trailing the points. The retaining means may comprise a roller 151 carried by the locking plunger 39<e> and engaging a cam slot 150 in the rocker arm 66 pivoted at 67. The arm 66 carries a member 71 for operating the plunger lock contacts 78, 79, and a spring plunger 170 adapted to engage a latching foot 169 carried by a pivoted member 159. If a train trails the points and the plunger 39<e> is not withdrawn from the lock rod L, contacts 78-79 will remain closed, but owing to the force exerted on the tongues, the pointdetector rod 63 will be displaced far enough to cause the roller 88 to leave the notch 89. As a result, the member 87 will be rotated to open the point-detector contacts, and the latch dog 156 will enter a notch 161 in the latch catch head 160. This causes member 87 to be held in the position in which the contacts 84-85 are open until the latch catch 157 is disengaged from the latch 156. In order to release the operating member 87 and permit the contacts 84-85 to close after being opened as above, the latching member 165 must be restored to its normal position by hand. When the contacts 84-85 are released, if the tongues have been distorted by the train, the plunger 39<e> will not re-enter the lock rod L when the points are subsequently returned to normal, and contacts 78-79 will remain open, thus insuring that the damaged condition will be indicated.

IPC: G01L11/00
Filed: 1968-05-24
Abstract: 1276294 Measuring fluid-pressure electrically DEFENCE SECRETARY OF STATE FOR 25 Aug 1969 [24 May 1968] 24839/68 Heading G1N A transducer for measuring fluid-pressure comprises a diaphragm 13, Fig. 1, exposed on its upper face to the test pressure and attached on its lower face to a moving coil 20 in the gap of a permanent magnet 22, 22a and also to a moving contact 24 co-operating with a spring-biased fixed contact 25. The coil 20 is energized via contacts 24, 25 causing the coil to raise contact 24 until the arm carrying contact 25 meets a fixed stop 26, whereupon the circuit is broken and contact 24 is again forced down to a position partly determined by the test pressure. Thus the mark/space ratio of the current through contacts 24, 25 is indicative of the pressure, which is measured by the average current through coil 20 or by controlling a separate oscillator 32. In another embodiment, Fig.3, the coil 20 is energized from the oscillator 32. An increase in test pressure causes the mark/space ratio of the output from the oscillator 32 to increase and the average current through coil 20 to increase to a value maintaining the mean position of the moving system substantially constant. In an alternative arrangement the moving system including coil 20 is replaced by a variable reactance forming part of a non-contact-making switching means replacing contacts 24, 25.

Title: Bistable laser structure
IPC: H01S3/10
Filed: 1965-06-14
Abstract: 1,112,420. Lasers. AMERICAN OPTICAL CO. 14 June, 1965 [15 June, 1964], No. 25129/65. Heading H1C. A bi-stable solid laser structure incorporates a light absorber having a coefficient of absorption which varies inversely with the intensity of light incident thereon of a wavelength of the laser light. In the arrangement of Fig. 1 (not shown) a crystalline or non-crystalline rod such as neodymium doped glass is positioned between two reflecting mirrors forming a resonant cavity. A light absorber is situated in the resonant cavity in alignment with the longitudinal axis of the rod such that when the rod is optically pumped light energy emitted by the laser is absorbed by the absorber to cause the total light energy losses to exceed the light energy available by the stimulated emission. There is thus no output from the structure. When the absorber is subsequently saturated by light from an external source it becomes transmissive and laser oscillations occur resulting in a light output which continues after the absorption control radiation is removed. Laser action is terminated by applying a quenching radiation into the active medium of the laser. The saturation and quenching radiation may be provided by other lasers. In the arrangement of Fig. 2 the laser active medium 10<SP>1</SP> is provided with a cladding of absorbing material 12<SP>1</SP> which is itself provided with a cladding 32, the refractive indices of these three materials n 1 , n2, n 3  being such that n 1 , > n 2 > n 3 . The reflective end 18<SP>1</SP> is bevelled such that the saturation control radiation 26<SP>1</SP> is transmitted through this end. When the absorptive cladding 12<SP>1</SP> is saturated and the active medium pumped laser oscillations occur following the path 20<SP>1</SP>, the angle # being such that the laser oscillations are reflected back into the core 10<SP>1</SP> and material 12<SP>1</SP>. In order to quench the laser, radiation 28<SP>1</SP> is incident on end face 16<SP>1</SP> so that it is incident upon interface 36 at an angle greater than the critical angle and does not penetrate the absorptive cladding 12<SP>1</SP>. In order to ensure that the saturating radiation 26<SP>1</SP> is retained within the cladding 12<SP>1</SP> a longitudinal groove is provided in the periphery of the laser rod 10<SP>1</SP>, Fig. 3 (not shown).

Abstract: 600,150. Indexing. GEAR GRINDING CO., Ltd., and ORCUTT, A. H. Sept. 28, 1945, No. 25258. [Class 83 (iii)] [Also in Group XXIII] In an indexing mechanism of the type wherein a peripherally notched rotatable index plate is associated with means for moving it intermittently, the index plate is in combination with an oscillatory member carrying a plate-actuating pawl, a locking lever for securing the pawl in operative position, and means for actuating the lever from a stationary ramp. A rocking member b is mounted coaxially with a notched index-plate a and stationary ramp x, and carries an arm d pivotally mounted at c, a tooth e on the arm engaging the notches in the plate. A projection on the arm extends through a gap in the rocking member to carry two fingers, one of which, q is slotted for radial movement on being displaced through contact with the ramp x, and the other, p is located by the common axis v, both fingers being spring-biassed against a side-stop s. On moving the member b clockwise the indexing plate is rotated, and towards the end of the stroke the finger q engages the ramp and rocks a member through a push-rod m to release a member g from engagement with the arm d. The engaging tooth e is then released by the contact of the finger p with the ramp x. On the return movement of the plate b, the tooth e slides on the periphery of the indexing plate until the spring-loaded plunger k urges it into the next notch. Wear on the tooth is reduced by the provision of a roller z engaging a ridge 2 on the index plate.

[Also in Division F2] A hydraulic motor has radial cylinders 10 with pistons 15 engaging an eccentric 14 through sliding shoes 16, a drive shaft 13 being connected to eccentric 14 and, through an Oldham coupling, to a rotary valve 17. The valve has annular channels 26, 27 communicating with inlet and outlet connections 22, 23, and with arcuate channels 24, 25 which sequentially register with cylinder passages 21. Pairs of balancing recesses 30, 31 at each end of the valve are connected to channels 24, 25 through bores in the valve. Plastics sealing rings 35, e. g. of P. T. F. E., are mounted in annular grooves, either the groove walls or the rings being fluted to prevent pressure build-up, Fig. 5 (not shown). Further pressure balancing of the valve 17 is provided by scallops 36, transverse passage 37 and axial passage (38) Fig. 3 (not shown). Piston shoe 16 engages the piston 15 through a ball head with a ring contact with the internal piston surface Fig. 4 (not shown). The shoe bearing surface 41 is hydraulically relieved by liquid from the working chamber passing through the piston and passage 42 and throttle 44. In Fig.8 (not shown), a filter (57) is mounted in the piston passage, and the throttle insert (44) is tapered to trap foreign matter and to lock the insert in position. Piston rings of P. T. F. E. are either wedge-shaped, Fig. 6 (not shown), or trapezoidal, Fig. 7 (not shown), so that axial pressure forces them into contact with the piston and the cylinder wall. The piston shoes 16 are located by rings 45 and discs 46. Rings 45 may be recessed into the shoes.

Abstract: 355,513. Lifts. WESTING- HOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.-(Assignees of Lewis, F. E. ; 364, Avenue A, East Pittsburg, U.S.A.) Aug. 26, 1930, No. 25419. Convention date, Aug. 26, 1929. [Class 78 (ii).] Electric plant.-In a lift system comprising a number of cages operating in adjacent shafts past the same floors, in order to prevent more than one cage in the bank from receiving calls for service at any given time there is provided for each cage a pair of block relays 4X, 4Y connected to be energized successively as the cage approaches the various floors. Resistances 35, 37 and 34, 36 are connected to the relays 4X, 4Y, respectively, through corresponding segments in group 23 on the " up " side of the floor selector FS, and resistances 39, 41 and 38, 40 are connected to the relays on the other side of the selector. Each resistance is a common member in a circuit for each cage. If a person at the third floor e.g. presses button F3U, the call is registered on the floor selectors of all the cages. As the first cage approaches the floor, a circuit will be completed for energizing the relay 4Y, which on closing its contacts inserts the resistance 105 in the circuit. The insertion of this resistance causes an increase in the voltage drop across the resistance 37, and a decrease in the voltage across the coil of the relay. If while the relay is actuated a second cage approaches the floor, a similar circuit will be completed by its floor selector, and the voltage drop across the resistance 37 increased to such an extent that the voltage available to the blocking relay of this cage is insufficient to actuate it. Therefore while the relay 4Y or 4X is energized, the corresponding relays of the other cages are ineffective to complete the call-receiving circuits of those cages. Cage-stopping relays 5X, 5Y, 6X, 6Y, associated with the relays 4X, 4Y, when actuated control inductor energizing relays 7X or 7Y to complete a circuit for the coils of slow-down inductor relays UR, DR to cause the cage to stop level with the floors.
