Title: Improvements in and relating to combustion gas turbine systems
Inventor: PUNCOCHAR JAROSLAV
IPC: F02C7/143
Filed: 1961-12-14
Abstract: 959,336. Gas turbine plant. PRVNI BRNENSKA STROJIRNA, ZAVODY KLEMENTA GOTTWALDA, NARODNI PODNIK. Dec. 14, 1961, No. 44935/61. Heading FIG. A combustion gas turbine system having an open wet circuit and a compressor in which the air is cooled by interstage injection of water is characterized in that the compressor stage group disposed after the final intermediate cooler operates with a greater compression than the preceding group, the compressed air from the compressor stage group following the final intermediate cooler is first regeneratively cooled in a heat exchanger and water is injected into the cooled air in a saturating device at a temperature and pressure higher than that of the air before injection, substantially all the heat of evaporation being covered by the enthalpy of the injected water and only a small proportion of such heat being covered by the enthalpy of the air, whereafter the water vapour saturated air is regeneratively heated in the same heat exchanger by the heat which has been removed previously. Atmospheric air is compressed in compressors K 1 , K 2 , K 3  and cooled by evaporation of cold water injected into the air in interstage coolers S 1 , S 2 . Air leaving the compressor K 3  at a pressure and a temperature, for instance, of 30 atmospheres absolute and 300‹C passes to a heat exchanger V 1  where it is cooled. Water is injected into the air in a saturator S 3  at a pressure and temperature greater than that of the air. Some of the water vaporizes and cools the air by about 10‹C but substantially all of the heat of evaporation is supplied by the enthalpy of the water. The air is then heated in heat exchanger V 1 , to a temperature about 30‹C lower than the temperature of the air leaving compressor K 3  and is passed through combustion chambers SK 1 , SK 2 , SK 3  and turbines T 1 , T 2 , T 3 . The exhaust gases are fed through a water heater V 2  to a flue. The heater V 2  heats the unevaporated water from the saturator S 3  which together with make-up cold water is circulated by a pump OC. The wet compressed air may be further heated by the turbine exhaust gases in a heat exchanger (not shown).

Title: Camera shutter arrangement
IPC: G03B9/34
Filed: 1975-10-30
Abstract: 1529204 Camera shutters ASAHI KOGAKU KOGYO K K 30 Oct 1975 [2 Nov 1974]  45030/75 Heading G2A A camera shutter has stops 11, 14 for preventing shutter closure, and an electromagnet 9 controlled by an exposure time T determining circuit (Fig. 5); the arrangement being such that if T is less than a predetermined time, the circuit de-energizes the electromagnet 9 to release the stop means after time T to close the shutter but if T exceeds the predetermined time, the circuit de-energizes the electromagnet 9 to save battery power after the predetermined time but the stop means is not released. Preferably in the second case the circuit re-energizes the electromagnet after time T and this releases the stops to close the shutter. In the arrangement shown: (1) exposure time T less than the predetermined time. Upon shutter release a lever 20 operates a lever 19 to release a shaft 1d whereby a gear 1 runs down and rotates a pinion 2 to rotate a shaft 2a of the opening curtain (not shown). A capacitor C 1  is charged by a current i dependent on T and after time T when Va =Vsl a switching circuit SW 1  is turned off and the electromagnet 9 is deenergized. This releases levers 10 and 11 for ACW motion, stop lever 11 thus moving out of the path of a gear 5 which runs down and rotates a pinion 6 to rotate a shaft 6a of the closing curtain 8. (2) exposure time T exceeds the predetermined time. Gear 1 operates the opening curtain as in (1) and after the predetermined time two things happen (i) gear 1 has rotated sufficiently for a pin 1c to strike a crank 16 which it moves CW to release a pin 14d and allow a spring 15 to move stop lever 14 CW into contact with a pin 10b. (ii) capacitor C2 charges up and turns on a switching circuit SW II  so that the collector potential of a transistor Tr rises. Since both terminals of electromagnet 9 are then held at the battery potential it is deenergized. This again releases levers 10 and 11 for CW movement but this time pin 10b of lever 10 moves stop lever 14 further ACW into the path of gear 5 to prevent shutter closure. Thus during the remainder of the exposure time the electromagnet is de-energized and battery power is saved. Eventually when Cl has charged such that Va=Vs1, circuit SW1 is turned off to re-energize electromagnet 9. This moves lever 10 CW which via pin 10b moves stop lever 14 CW to release gear 5 and allow shutter closure. Electromagnet 9 stays energized until capacitor C2 has discharged (discharging having been initiated by the switching off of circuit SW1.

Abstract: 1,215,964. Endless conveyers. JOY MFG. CO. 25 Sept., 1968 [25 Sept., 1967], No. 45501/68. Heading B8A. A conveyer chain comprises flight members 18 connected by roller link members 12, 14, 16 and by a universal link 22. With bending of the chain in a direction parallel to a support surface for the chain taking place only at single points between the flight members and with those points spaced from the flight members, the positioning of the flight members normal to the direction of motion is stated to be more stable and better controlled than when a universal link is immediately adjacent each side of the flight members. There may be more than one universal link between a pair of flight members 18 to provide a greater amount of flexibility parallel to the support surface but at least one roller link 12 or connecting link 14 should then be used between successive universal links as well as between a flight member 18 and the nearest universal link.

Title: Braking systems for electrically operated escalators
IPC: B65G43/06
Filed: 1973-10-01
Abstract: 1442652 Emergency brakes HITACHI Ltd 1 Oct 1973 [29 Sept 1972 28 March 1973] 45683/73 Heading F2E A braking system for an electrically-operated escalator includes apparatus for selecting the direction of travel of the escalator, brakes for frictionally stopping the escalator driving mechanism in response to a signal from an emergency switch, and braking-pressure control-apparatus for applying a first braking pressure in the event of downward travel, and a second braking pressure, which is less than the first, in the event of upward travel. In Fig. 4, component 13 is part of a pivoted arm on the right of which is secured a brake shoe (not shown) co-operating with the exterior of a drum on the shaft of a motor driving an escalator. Component 15 is a brake-applying spring; a solenoid (not shown) mounted between the end of arm 13 beyond its pivot and the end of a similar spring-loaded brake arm is energized to pivot the arms against their springs to release the brake. A controlling circuit, (Fig. 5, not shown), includes an emergency switch and a two-way switch, the latter being used to govern the direction of travel (up or down) of the escalator. In operation of the escalator, the emergency switch is first closed, and the two-way switch is closed to drive the escalator in, for present purposes, the upward direction; in consequence, the brake solenoid is first energized, releasing the brake, and the drive motor is started inro tation in the appropriate direction; then a servomotor 21, Fig. 4, is energized, thereby driving gears 22, 19, which permit spring 15 to expand and push seat 18 and gear 19 to the left until bracket 26 on spring seat 18 operates a limit switch 34 to de-energize the servomotor. (If the gears &c. had been in this position initially, the servomotor would not have been energized). To effect an emergency stop, the emergency switch is opened, whereupon the driving motor is de-energized and the brake solenoid is de-energized. Then because spring 15 has been decompressed, the deceleration is not excessive even when the escalator is fully loaded. On the other hand, for arrest of downward movement, the spring is in the compressed condition of Fig. 4, so the deceleration is greater. In Fig. 11 a main solenoid 1130 when energized forces apart levers 1116, 1118 about pivots to release brake shoes 1114 from drum 1112, against the force of a spring 1124. If the escalator is travelling upwards when the emergency switch is opened, solenoid 1130 is immediately de-energized, permitting brake application by spring 1124; after a delay an auxiliary solenoid 1132 on the other side of the lever pivots is deenergized, whereupon springs 1160, 1162 act on the levers to increase the braking pressure. If the escalator is travelling downwards both solenoids are immediately de-energized for emergency stopping. In Fig. 6 (not shown) a main and an auxiliary solenoid are mounted between the levers on the same side of the drum.

Abstract: 1,133,009. Automatic phase control systems. COMPAGNIE FRANCAISE THOMSON HOUSTON - HOTCHKISS BRANDT. 21 Oct., 1966 [22 Oct., 1965], No. 47369/66. Heading H3A. A system as in Specification 673,957 for synchronizing the phases of two transmitters which are coupled to a common aerial through a hybrid ring, a dummy load being connected to the terminal of the ring opposite the aerial terminal, is characterized in that the phase control loop is interrupted when excessive power is dissipated in the dummy load. This has the effect of reducing large phase errors. For example, if the phase error is 300 degrees reduced to 30 degrees by the A.P.C. loop interruption of the loop will result in a phase error of 300 degrees which is equal to - 60 degrees; when the loop is re-connected the phase error will be reduced to - 6 degrees. The phase discriminator may comprise a second hybrid ring supplied across one diagonal with signals derived from the transmitter outputs and subjected to a 90 degree relative phase shift, the other diagonal being connected through oppositely poled diodes to a variable phase shift network in the path of one of the transmitters.

Title: A Mechanism for Positioning a Spheroidal Type Head to Present a Selected Type to a Print Position
IPC: B41J7/54
Filed: 1968-10-08
Abstract: 1,188,440. Typewriters. BURROUGHS CORP. 8 Oct., 1968 [19 Oct., 1967], No. 47704/68. Heading B6F. A type-selecting mechanism for rotatably positioning a type-head 24, Fig. 12, includes a floatably mounted code-plate 90 which limits against selected ones of an upper group of retractable stop members 140, 142, 144, 146 and a lower group of retractable stop members 148, 150, 152, Fig. 14. The code-plate 90 is operatively connected to the type-head 24 via a pivoted lever 68 carrying a pulley 80 over which a band 70 passes, the band being anchored at 72 to the machine frame 55 and connected at its other end to a pulley 86 spring-loaded with a torsion spring to keep the band 70 taught. The typewriter, Fig. 1, includes a support frame 20 and a cyclically operable shaft 22 driven by an electric motor via a one-revolution clutch and sprocket 50. The printing head 24 is mounted on the upper end of a rotatable shaft 27 journalled in an arm 28 pivoted on a stationary shaft 32. A cam 38 affixed to the shaft 22 operates on a cam follower 36 to thrust the head 24 against a platen (26, Fig. 2). A further cam 66 affixed to the shaft 22 cooperates with a cam follower 64 on a pivoted lever 60. A bifurcated extension 106 of the lever 60 engages a stud 108 mounted on a bell-crank lever 112 pivoted at 114. At the start of a type-selecting cycle, two studs 94 and 120 on the code-plate 90, Fig. 4, are engaged respectively by the upper and of lever 60 and the lower arm (118, Fig. 4) of bellcrank lever 112 to move the code-plate 90 in a first direction away from stop members or pins 140 to 152. As the cycle continues, the code-plate 90 returns in the opposite direction under the influence of the torsion spring acting on the band 70, and also a spring (125, Fig. 4), until it abuts against the selected stop members or pins, thereby defining the position of the pulley 80 carried by the lever 68. The right edge of the code-plate 90, Fig. 4, has a number of relatively offset abutment recesses 126, 128, 130, 132, 134, 136 and 138, of relatively different depths with respect to the edge. The stop members or pins are selectively retractable by four solenoids S 1 , S 2 , S 3  and S 4 , Figs. 3 and 8) in a permutative system or code. The stop members 149 and 142 are coaxial and integral, the stop member 142 being of reduced diameter for engagement by the relatively deeper abutment recess 128 in the code-plate 90. Normally, the larger diameter stop member 140 is in the path of code-plate 90 and is retractable to place the smaller diameter stoppin 142 in the said path. Stop members 148 and 150 are similarly constructed.
