Title: Improvements in or relating to automatic starting of turbines
Inventor: STEHLIK JOSEF
IPC: F02C7/26
Filed: 1967-08-30
Abstract: 1,202,903. 903. Programmed control of gas turbines. PRVNI BRNENSKA STROJIRNA ZAVODY KLEMENTA GOTTWALDA. Aug.30, 1967, No.39685/67. Heading G3N. [Also in Division F1] A turbine is automatically started after the automatic pre-setting of starting conditions on receipt of a signal, by the receipt of a further signal. As shown, the depression of a pushbutton 2 activates trip relays 3 which, over lines 16, prepare the turbine for start-up. The preparation is monitored, over lines 17 by a logic circuit 4. A push-button 1 is then depressed to commence the start-up of the turbine if the logic circuit indicates that preparation is complete. A relay 5 sends out a pulse to engage a clutch 18, on completion of which, a return pulse is sent to the relay which sends a signal to engage the turbine turning gear 15 and connect an electric starter motor 9 to a supply through a switch 10. The speed of the starter motor is controlled through a resistance 11 supplied with constant current through a current-sensitive relay 6. At a predetermined motor speed the output of a tachogenerator 12 operates a voltage-sensitive relay 13 which sends a signal to the relay 5. Upon receipt of this signal the relay 5 operates a device 22 which ignites a flame in the gas turbine combustion chamber 21 which is controlled by a flame detector 8. The indication to relay 5, from the detector 8, of a controlled flame causes the relay 5 to bring in a second current-sensitive 7 for operating the starter motor 9 under full-power by adjusting resistance 11. A fuel valve 24 is then opened and the fuel supply increased by a controller 23. At a speed determined by the tachogenerator and a voltage sensitive relay 14, the starting apparatus is shut off and at a higher speed determined by a voltage-sensitive relay 15, the relay reduces the addition of fuel by the starting controller 25 and the control of the turbine is taken over by a speed controller 25. The starting controller 23 then ceases operation and the servomotor of the resistance 11 returns it to the starting position. When a push-button 20 is depressed during the starting procedure the fuel valve 24 is shut. off and controller 23, motor 9, resistance 11 and the ignition device 22 returned to the starting condition. The turbine is then restarted by depression of push-button 1.

A toy multi-storey car park comprises a vertically stacked array of box-like cells for accommodating toy vehicles, an open-ended cab to accommodate a toy vehicle, motor means coupled to said cab to enable the cab to be aligned with any cell, and means which in one operating position transfer a vehicle from the cab to the cell aligned therewith and in a second operating position transfer a vehicle from the cell into the cab. As illustrated the vehicle is transferred from the cab 62 into a cell or down an exit ramp by tilting the cab floor by a mechanism attached to a lever or levers 91, 92 on the exterior of the cab. The same lever or levers may also be operated to transfer a vehicle from a cell into the cab by tilting the floor of the cell, while at the same time raising a stop at the rear of the cab to prevent the vehicle overshooting the cab. The floors are pivoted at their front edges and each one has a plate at the front, at right angles to and below the plane of the floor, upon which a plate emerging from the cab, at a suitable setting of its lever or levers, presses to tilt the cell floor. The cab is mounted on two rods, R 3  and R 4  which are moved vertically and horizontally respectively by means coupling them to separate, reversible electric motors. The means may be strings, attached via pulley systems to one end of each rod, the rods being guided by having pinions on their ends which move along guiding racks, or strings attached to both ends via suitable pulley systems. In another embodiment the cab moves between two towers of cells and vehicles may be transferred to cells and vice versa through either end of the cab. The bottom cell on each tower serves as an exit and is supplied with a suitable ramp.

Abstract: 1,048,306. Flexible cables. BOSTON INSULATED WIRE & CABLE CO. Oct. 7, 1964, No. 40828/64. Heading H1A. The Figure shows a lift cable intended to provide adequate flexibility or stiffness without wearing itself or fouling the cage or shaft walls. This is achieved by allowing considerable circumferential movement to the layers of conductors 32, 34, 36 so that they can accommodate bending while the stiffness is controlled by the sheaths 40, 42, 44 of the cable. The cable consists of a central strengthening member 30 around which are laid three relatively loose layers of conductors 32, 34, 36 the angle of lay of these conductors being between 65 and 68 degrees. Next a cotton braid 40 with a lay angle of 45 degrees is applied. Its lay angle is sufficient to ensure that it contributes some stiffness to the cable but it does not grip the conductors and acts merely as a cushion. Next, two tapes 42 are applied. They are made of a woven cotton with a backing of resilient yielding material such as rubber and are wound at an angle exceeding 45 degrees so that the warp contributes to the stiffness of the cable. Outside this is a braid 54 consisting of non-metallic threads with a lay angle of more than 45 degrees. The stiffness of this sheath provides the majority of the stiffness of the cable; it is impregnated with asphalt, rubber or plastic.
