Title: Improvements in or relating to timing devices for electrical relays
IPC: G01R31/327
Filed: 1931-02-11
Abstract: 370,562. Clocks. PALMER, R. W., Crowhurst, Kingsway Crescent, North Harrow, Middlesex. Feb. 11, 1931, No. 4226. [Class 139.] Short-time movements.-A device for timing the operation of electromagnetic relays &c. has the timing operation effected visually by observing the relay contact springs by light passing through an orifice and arranging for them to be operated just before the orifice is closed by a shutter operated under the control of a timing member. As shown in the Figure, the apparatus is set by the depression of a handle 2 which is connected to a chain 15 passing over sprockets 30, 31, 17. The sprocket 17 is loosely mounted on a shaft 20 and carries a pin 18 which engages a pin 19 on a pinion wheel 40 attached to a catch-plate 39, also mounted on the shaft 2, the plate 39 being carried round until a notch in its periphery is engaged by the hooked end of a starting lever 24 operable through a pushbutton 21. During the setting operation, the wheel 26 engaging the pinion 40 is rotated freely on the shaft 28 without turning an escapement wheel 27, a free-wheel coupling being inserted between wheels 26, 28, but a spring 46 is wound up in readiness for returning the wheels 39, 40 under the control of the escapement 29. During the winding up of the spring a pin 25 attached to the pinion wheel 40 engages first with a rocker 9 to cause a pair of shutter flaps 5, 34 to uncover an orifice 33 through which the contact springs of the tested relay are to be observed as by the light of a lamp 14 and later engages a second rocker 12 operating contact springs 11 connected to terminals 35, 36, 37 across which the windings of the tested relay are connected. In the return movement of wheels 39, 40 which is controlled by the escapement, the pin 25 first engages the rocker 12 to initiate operation of the relay under test and then operates the rocker 9 to close the shutters 34. The time which elapses between these two operations is adjusted by means of a disc 23 friction-tight on the shaft 20 and carrying the pivot pin 13 of the rocker 12, the pivot pin 42 on the rocker 9 being mounted on the fixed framework 1. The disc 23 bears graduations on its periphery cooperating with a fixed pointer 22 and the angular position of this disc is adjusted by trial until the contacts of the tested relay are operated just before the orifice of 33 is covered. The time of operation may then be read off on the scale on disc 23 which may be graduated in milli-seconds. The rocker 9 may control contacts 10 which with contacts 11 mav be connected to an oscillograph for calibration purposes. In an alternative arrangement the lamp 14 is arranged immediately behind the orifice 33 and the movement of the contact springs observed by light passing through the orifice, it being arranged that the contacts operate just before the shutters 5, 34 cut off the light of the lamp 14. Observations by this method cannot, however, be made of relays situated in brightly lit positions.

Abstract: 252,246. British Thomson-Houston Co., Ltd., and Whitaher, F. P. Feb. 19, 1925. Synchronizing dynamoelectric machines. - A motor - converter is started by an apparatus comprising resistance and reactance such that at starting at least the resistance is connected to the slip-rings and when the desired speed is reached the resistance is rendered ineffective and the reactance alone is left in circuit with the rings. In the form shown in Fig. 2, the resistance a is connected to the rings b at starting, and when the converter has reached a nearly synchronous speed the switch d is thrown over so as to replace the resistance by a reactance c. A switch e may be provided for short-circuiting the reactance when the machine has dropped into synchronism. The resistance and reactance elements may be connected in series, as shown in Fig. 3, the two-way switch d being thrown upwards for starting on the resistance with the reactance short-circuited and downwards, thereafter, for synchronizing on the reactance with the resistance short-circuited. A second switch e enables the rings to be short-circuited for permanent running. Alternatively, both resistance and reactance may be in circuit with the rings at starting, the resistance being so operated subsequently as to leave the reactance alone in circuit for synchronization.
