Title: Improvements in and relating to starting control arrangements of gas turbines
Inventor: RIZK WAHEEB
IPC: F02C7/26
Filed: 1959-05-15
Abstract: 950,181. Starting prime-movers. ENGLISH ELECTRIC CO. Ltd May 13, 1960 [May 15, 1959], No. 16724/59. Heading H2H. [Also in Divisions Fl and G3] During starting of a gas turbine the energy supplied to an electric starter motor 1 is increased, and so also is the turbine fuel supply, by fluid pressure responsive devices connected to an hydraulic pressure generator 2 coupled to the starter motor. Rising pressure in the line 22 increasingly closes an obturator 17 in a bleed unit connected to a separate control fluid line 27; this second control fluid acts on the piston 51 of a spring-loaded fuel valve 101, the valve progressively opening as the obturator closes. The starting motor is accelerated by the sequential short circuiting of resistors 10, 11, 12 by pressure-operated switches 4, 5, 6. The motor may be D.C., the resistors being in the supply circuit, or A.C., when the resistors are in the rotor circuit. Another pressure switch 31 initiates a timing device 37 controlling an igniter 36 and its gas supply valve 33, and a further switch 32 opens a second fuel supply valve 39. At self-sustaining speed another pressure switch 14 disconnects the motor and, in the arrangement shown, closes a valve 29 to cut off the control fluid bleed unit. The clutch 26 is also disconnected. At this speed a time controlled cam starts to rotate to progressively close a second bleed 54, so that the fuel supply is further increased to run the turbine up to governing speed. Another bleed valve 53 is controlled by devices (not shown) sensitive to turbine temperatures or pressures, fuel to air ratio or the like. If the motor 1 fails to stop, a final pressure switch 56 shuts down the turbine. In an alternative arrangement the clutch 26 is between the motor 1 and the pressure generator drive so that this continues to be driven by the turbine. In this case the bleed unit is kept in operation up to governing speed, and so obviates cam-controlled bleed 54. The pressure generator 2 may be a positive displacement or a centrifugal pump, with a temperature sensitive valve 21 or other means to compensate for varying viscosity of the fluid, or it may be a total pressure head device (Fig. 2, not shown). This control fluid may be part of the fuel or lubricating oil system.

Title: Solenoid operated print mechanism
IPC: H04L17/26
Filed: 1970-04-08
Abstract: 1306514 Selective printing MITE CORP 8 April 1970 [22 Aug 1969] 16745/70 Heading B6F A selective printer includes a movable type body 176 and a solenoid summation system to move the type body to a selected position. The solenoid system comprises a plurality of opposing pairs of solenoids 116, 118; 120, 122; 124, 126; each pair being connected together so as to provide simultaneous displacement of both solenoids in a pair when one or other is energized. The sum of the displacements is transmitted to the type body to selectively position it. In the particular embodiment a pulley system is used to axially displace the cylindrical type body, and a differential lever system (Fig. 11) is used to rotate the type body via pinion 194. The opposing pairs of solenoids enables each successive character to be selected without the summation system having to return 'to a datum position. Aligning for impression; hammer mechanism (Figs. 13, 18 and 19).-Alignment of impression is achieved with an electromagnetically operated pawl (256, Fig. 13) engaging a detent wheel 258 which is secured to splined rod 174. In addition, the hammer head (252, Fig. 18) is articulated to the hammer body and pivots about a point (336). An initial impression tilts the hammer head which is then retained in this tilted position by the light-friction exerted by a U-shaped spring (346). Letter spacing.-The type body and the hammer mechanism are stepped along the line by an electromagnetically operated ratchet and pawl mechanism (Fig. 4), carriage return being provided by a coil spring (208). The drive is transmitted via the belts of the pulley summation system to the type body carriage, and via a cable (192, Fig. 3) to the hammer carriage 184. As an alternative, the type and hammer carriages may be stationary and the record material stepped along the line. At the end of the "carriage return" a pin (215, Fig. 14) on the ratchet engages a lever (217) forming part of the pawl resetting mechanism. A pad (213) cushions the force occurring when the pin (215) hits the lever (217).

Abstract: 1,003,509. Pneumatic despatch apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 23, 1964 [May 20, 1963], No. 16774/64. Heading B8A. [Also in Division G4] Film strips are stored in tubes 12, Fig. 1, and a single path between a tube 12 and a reading station 54 may be set up through tubes 24, 38, 52 whereby a selected strip may be driven pneumatically to station 54. Bin 10 may be moved by horizontal and vertical cylinders 14b, 14v by one position in either or both directions to align different groups of 16 tubes 12 with the 16 tubes 28. Similarly plates 26 which has 16 holes and plate 36 which has four holes may be moved by cylinders 28h, 28v to align tubes 38 with different groups of four tubes 24. Finally, plates 40, 50 may be moved to align tube 52 with one of tubes 38. Having established a path from a selected tube 12 to tube 52, vacuum is applied by valve 74 to draw the selected strip into station 54. Each strip, Fig. 3a, has space for recording up to 32 documents, any one of which may be aligned with station 54 by means of a stop 56 which is selectively positioned by means of weighted pistons 66 controlled by valves 68. The recorded document aligned with station 54 may be optically projected for viewing or may be recorded on film 60. The strip is returned to its position in bin 10 by applying air pressure from valve 74. The end 84 of each film strip has a circular crosssection and fits snugly within the transport tubes to act as a piston. Switches associated with stop 56, Fig. 1, detect the pressure of the strip in station 54 and also detect whether the strip has been rotated during its passage from bin 10, a pneumatic device 72 being controlled by these switches to rotate the strip into the correct position when this is necessary. A pair of contacts at bin 10 are closed pneumatically when a strip has been returned to its storage tube 12. Detailed control circuits for the system are described. A plurality of bins 10 and reading stations 54 may be combined in a single system to enable any strip selected from any one of the bins to be transported to any one of the stations 54, and if desired, several strips may be selected from different bins and transported to different stations 54 simultaneously. Since the system can be made light-tight, the film strips may be partially unexposed whereby further documents may be recorded thereon.

Abstract: 145,520. De Laval Separator Co., (Assignees of Leitch, M.). March 1, 1917, [Convention date]. Cow-milkers. - Relates to milking-machine claws for double-chambered teat-cups of the type having a milk passage connected to the inner chamber of the cups and a pulsator valve for controlling the admission of air and suction to the outer chamber, such as described in Specification 10967/14. According to the invention, the milk passage a fitted with branches c is readily attachable to or detachable from the pulsation member d, which also carries branches m, n. Hooks r, s on the two members are brought into engagement by a longitudinal movement of the members, and when connected the branches c, m are in close proximity so that the flexible tubes o, p when in position prevent the relative movement necessary to disconnect the hooks. The branches c, m are so arranged as to form guides to maintain the members a, d in a parallel position. The pipe g connects directly with an exhaust and the pipe f with a pulsator. The differential piston e is moved by the variations of pressure at its larger end, the smaller being under atmospheric pressure. The annular spaces l, k, each of which communicates with a pair of branches m, n, are thus brought alternately into communication with the vacuum pipe g, and with the atmosphere either directly or through passages h, i.
