Abstract: 674,084. Thermal switches; snap-action switches. CRABTREE & CO., Ltd., J. A. June 22, 1950. [July 21, 1949] No. 19202/49. Class 38 (v). A switch which is opened on overload by thermal releases, such as those of Specification 624,581, has means which are adjustable to enable the contacts to be reset either automatically or manually. The trip-bar d of the releases a acts on a spring blade e riveted at g to a channelled member f, the other end of the blade e engaging V-notches h<SP>2</SP> in a member h so as to form a toggle, the other end of member h being pivoted to a blade spring i having an end hooked into an aperture l<SP>1</SP> in a resetting blade l. The latter is riveted at m to a fixed bracket n, and has a forked end to receive the rivet g. The upper bent-over end of member f is also hooked into aperture l<SP>1</SP>. Normally, the blade l presses the centre of the toggle to the right, Fig. 1, so that a contact o carried by spring i engages a fixed contact o<SP>1</SP>. On overload, the toggle is moved over-centre, Fig. 2, and contact o moves to the right until arrested by a stop s<SP>1</SP>, the position of which is adjustable by rotation of a plunger r having a cam which can engage the stop as claimed in Specification 674,119. In the Fig. 1 position, the cam r<SP>1</SP> is disengaged from the stop which prevents excessive movement of contact o which can thus be reset automatically by blade l. If the cam is rotated, the stop is moved to a position, Fig. 2, wherein the contact moves so far to the right that the toggle cannot return automatically, the contacts being reclosed by depression of the plunger so as to release the cam from the stop which moves to the Fig. 1 position, taking contact o with it. The plunger has a rib (not shown) co-operating with a fixed projection to prevent rotation of the plunger without initial depression thereof. A contact 6 carried by the plunger co-operates with fixed contacts n<SP>2</SP>, 7, respectively connected to contact o.and a terminal 2, so that the circuit may be broken by depression of the plunger. The stop is connected to a pilot lamp which is lit when the stop is engaged by the contact o. Specification 609,143 also is referred to.

IPC: H03K3/78
Filed: 1961-05-30
Abstract: 982,894. Pulsing carrier frequencies; valve oscillator and pulse circuits; cathode ray oscilloscopes. ZENTRALINSTITUT FUR KERNPHYSIK. May 30, 1961, No. 19521/61. Headings H3F, H3P, H3R and H4T. A U.H.F. oscillator generates oscillations of phase demined by the leading edge of pulse and reaching a maximum limited amplitude during the first half cycle of oscillation and is used for generating calibrating marker pulses on a C.R.T. time base. Sharp positive pulses are applied to the grid of a pulse steepening valve 4 with small output capacitance Ca so that the Ia leading edge slope - is steep- Ca ened, and the negative going anode voltage applied to the cathode of an oscillator valve 6 whose tuned circuit is so highly damped by normally conductive forwardly biased diodes 10 that oscillations are not generated until the diode<SP>s</SP> 10 are blocked by the resulting negative excursion of the oscillator anode voltage. The #-network tuned L circuit 26, 27 being of high Q and - ratio, C oscillations build up immediately (within half a cycle) to a maximum amplitude limited by the diodes 10 (although feedback is small, for high stability). The oscillations are then fed to a Class C amplifier 13 so that " flat-topped " cycles are applied as marker pulses to the C.R.T. The output capacitance of valve 13 and input capacitance of the C.R.T. provide with the series inductor 22 a # circuit for the highest selected oscillator frequency (e.g. 1000 mc/s.) and, with the shunt inductor 23, a parallel resonant circuit, for the next lower frequency range. The tuned circuit 26, 27 is connected to the oscillator grid and anode by switch contacts 24, 25 so that a frequency range change may be made, and feedback is made independent of frequency by a large value of capacitor 9. The pulse sharpening valve 4 may be in parallel with a further valve fed with a differentiated trigger pulse, whose output is added to that of valve 4 to further steepen the output pulse leading edge.
