Title: A safety device for the protection of the stability of turboalternators operating in parallel connection against excessive rotational speeds and runaways
IPC: H02J3/08
Filed: 1955-03-29
Abstract: 782,704. Supply systems comprising a plurality of sources. LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT. March 29, 1955 [March 29, 1954], No. 9090/55. Class 38 (4). A turbo alternator 1 operating in parallel with other sources connected to bus-bars R, S, T, is protected against instability by apparatus responsive to the load angle of the machine, i.e. the phase angle between the bus-bar voltage and the pole voltage of the machine, and which, upon the angle exceeding a limit value, operates contacts to give a warning, effect a regulation of fluid supply to the turbine, or shut the machine down. The apparatus may comprise a contact-making synchroscope 6, the windings of which are fed, respectively, by the bus-bar volts (over transformer 4) and by a reference voltage representative of the pole volts of machine 1. This latter voltage may be provided by a suitably phased auxiliary machine 2 driven with the machine 1, or by an auxiliary unloaded winding on the machine 1 or its exciter. The moving element of the synchroscope thus takes up a position corresponding to the load angle of the machine. Upon the limiting load angle being reached, the synchroscope closes contacts 9 to give a warning. If the angle increases sufficiently for the synscope to close contacts 10, synchronism has been lost, and these contacts cause closure of a switch 13 to energize from the machine 1, the rotor of a motor 7 for regulating the steam supply to the turbine and having a stator energized from the bus-bars. The motor rotates at a rate corresponding to the slip frequency. If this adjustment is inadequate to restore stability, the synchroscope rotates further and closes contacts 11 to operate quick shut-off means for the turbine. A regulating disc 14 may be driven by the motor to operate further control contacts. The synchroscope may be replaced by a slip ring induction motor 12.

Title: Slack adjusters
Inventor: MARSH GERALD CRANTON
IPC: B61H15/00
Filed: 1962-03-09
Abstract: 959,717. Slack adjusters; linkwork. GRESHAM & CRAVEN Ltd., and GIRLING Ltd. Feb. 26, 1963 [March 9, 1962], No. 9171/62. Headings F2E and F2K. A slack adjuster comprises a sleeve 18, two telescopic elements 1, 3, element 1 having a threaded portion engaged by a nut 2 relative rotation of which in one direction serves to telescope the elements 1, 3, a first driving oneway rotary clutch device 6, 7, 8, which engages a helical guide 19 on the sleeve by which, upon relative axial movement in one sense of the two elements and the sleeve, one part of the clutch is rotated and, through the clutch being thereby rendered operative, the nut is rotated in said one direction, and a second locking rotary friction clutch device 15, 20 engaged by an axial guide 21 in the sleeve, the second device being operative to prevent rotation of the nut in the opposite direction upon relative axial movement in the opposite sense of the two elements and the sleeve. The outer screw-threaded ends of the two elements constituted for the one part by spindle 22, end cap 13 tube 4 and barrel 3 and the other part by the spindle 1 are connected serially in the brake rigging of a railway wagon. In the initial position the internal parts are displaced to the right from the position shown with spring- loaded pawl-and-ratchet devices 8, 6, 15, 20 disposed adjacent the right-hand end of slot 19 and 21 respectively. As the brakes are applied by pulling spindle 22 to the left the internal parts of the adjuster will move to the left, against the spring 17, relative to the sleeve 18. Such movement causes pawl 8 to be rotated relative to the tube 4 as the radial extension of housing 7 moves down the helical slot 19, pawl and ratchet device 15, 20 preventing rotation of tube 4. If adjustment is required, the pawl 8 will ride over one or more teeth on the ratchet 6. Consequently, on return of the spindle 22, the pawl 8 will rotate in the opposite direction and cause the ratchet 6 and thus tube 4 and nut 2 to be also rotated. Such movement will telescope the spindle 1 relative to the barrel 3. Manual adjustment of the adjuster may be made by rotation of the nut 2 after the lever 10 has been pivoted downwardly so as to retract the pawl 8 from the ratchet 6. In a modification, the pawls 8, 15 are carried by the tube 4 and engage ratchets on the housing 7 and end cap 13.

Title: Alarm delay mechanism for alarm clock
IPC: G04B23/10
Filed: 1965-03-04
Abstract: 1,058,531. Alarm clocks. GENERAL TIME CORPORATION. March 4, 1965 [March 4, 1964], No. 9326/65. Heading G3T. An alarm clock includes means responsive to a first condition of register between the usual co-operating hour wheel (50) and indicator or setting wheel (70) for initiating ringing of the alarm at the set time, means operative after a short time, e.g. a few seconds, automatically to stop the alarm, and means responsive to a second condition of register, some time, e.g. eight to ten minutes, after the alarm has been so stopped, to re-activate the alarm and initiate a sustained period of ringing. In winding the clock, a pinion (23), Figs. 1 to 5 (not shown), on a winding shaft (24) moves a toothed segment (91) to the position in Fig. 2A where the segment clicks idly against the pinion under the bias of spring arm (101), (102). At the pre-set time, hour wheel (55) drops on to shoulders (71a), Fig. 5C, of cams (71), (72) on the indicator wheel (70), thus releasing a spring detent (80), (82) from the clapper (65), and the alarm spring commences to unwind. Pinion (23) re-engages the segment and rotates it to the other extreme position, where it again clicks idly. A cam (93) on segment (91) has now returned the detent (80), (82) to the alarm disabling position. After a further period, the hour wheel (55) drops off the shoulder (71a) to lower the segment (91) Fig. 5B and thence the detent (80) from the disabling position, whereby a sustained ringing is initiated. To prevent running down of the mainspring, this period is limited by a detent wheel device (110) engaged by the time train pinion (111) and having a lug (114) which locks the pinion (23).

Abstract: 414,465. Photographic roll - film reflex cameras. STEENBERGEN, J., DIEBEL, O., FRAUENSTEIN, H., ENGLISCH, E., SCHUBERT, H., and KOCH, C., (trading as IHAGEE KAMERAWERK STEENBERGEN & CO.), 24, Schandauer Strasse, Dresden, Germany. March 28, 1933, No. 9371. [Class 98 (i).] In a reflex camera for roll-films in which the winding of the film, setting of the focal plane shutter and moving of the mirror into position for focusing are effected by a single winding knob, connected to the film winding axle directly and to the shutter winding shaft through gearing and a friction clutch, the clutch comprises a spring frictionally connected to the knob and operatively connected to gearing driving the shutter winding shaft, and the mirror is set by a cam on the shutter winding shaft. In the form shown, the film is wound by a knob 7, Fig. 6, the shaft 8 of which is encircled by a spring 16 anchored to a pinion 9, driving the shaft of a roller-blind shutter through gearing 10-15. Reverse rotation of the shaft 8 is prevented by a spring 21. The mirror 34 is set by a cam 27, Fig. 9, on the shaft of the shutter which during the winding bears on a lug 33 on a pivoted plate 30 bearing a pin 32 which presses the mirror into position for focusing where it is retained by a spring catch 36. The pinions 10 and 15 are carried by a plate pivoted to the wall of the casing. Pressure on the shutter release 23 moves an arm 24 to rock the plate carrying the pinions 10 and 15, the pinions 12 and 15 being thereby uncoupled allowing the first roll of the shutter to run down. At the same time a nose 19 on an arm 44 engages a pin 18 on the pinion 11 preventing the second roll of the shutter from running down. When the shutter operating member 23 is released, the nose 19 is withdrawn from the pin 18, and the second roll of the shutter runs down.
