Filed: 1966-07-12
Abstract: 1,100,179. Recording-apparatus; speedometers. KIENZLE APPARATE G.m.b.H. July 12, 1966 [July 15, 1965], No.31255/66. Headings G1J and G1K. Apparatus for recording speed and periods of rest and motion of a vehicle comprises two styli and an electronic pulse generator whose pulses energize a solenoid 31, the carriers 5, 19 co-operating in such a way that when the vehicle starts the armature 29 of the solenoid 31 applies mechanical vibration pulses to one stylus 22 to record motion while the other stylus 6 records speed and when the vehicle stops the other stylus 6 is vibrated to record rest. A speedometer with copper eddy current drum 16 and return spring 18 drives the stylus 6 through rack 10 and pinions 10, 11, 14, while the vibrations of the armature 29 are transmitted by a lever 25 and a coupling rod 24 to the stylus carrier 19. When the speed drops to zero the slide 4 (carrying the rack 10 and stylus carrier 5) returns to a zero stop 34, a lug 33 on the slide 4 contact the vibrating lever 25 and a laminated spring 35 on the slide 4 holds the stylus carrier 19 clear of the coupling rod 24. To distinguish the driving times of different drivers of the same vehicle the width of the bar diagram is varied by providing the drivers with individual keys for adjusting the apparatus from outside to preset the amplitude of the mechanical vibration pulses. The adjustment may switch the application of the pulses of the electronic generator from one solenoid 31 to two solenoids 31, 32 in parallel arranged to increase the amplitude of the resulting mechanical vibration pulses. In another embodiment, Fig. 3 (not shown) the amplitude of vibration of the stylus carrier 19 (36) can be set by turning a lever (46) carrying three different limit stops to select the appropriate one for co-operation with an abutment (39) on the carrier (36). In the embodiment of Fig. 4 (not shown) the stylus 22 recording the "in motion" bar diagram is provided with a supplementary source of mechanical vibrations in the form of a pendulum mass (56). When the vehicle stops the slide 4 carrying the speed recording stylus 6 closes an electric contact to energize a solenoid (59) for clamping the carrier (36) of the stylus 22 against vibration.

Title: Improvements in or relating to thermionic valve oscillators
IPC: H03B5/38
Filed: 1945-11-24
Abstract: 599,963. Valve generating circuits. ERICSSON TELEPHONES, Ltd., and HOPWOOD, F. W. Nov. 24, 1945, No. 31737. [Class 40 (v)] In a thermionic valve oscillator having positive and negative feedback paths, the amount of negative feedback is controlled by a non-linear impedance which is connected across the secondary of a transformer, the primary of which is connected to the output circuit. The use of the transformer, which is arranged to step up the current through the non-linear impedance, enables the non-linear characteristic to have increased effect. Fig. 3 illustrates one form of the invention, comprising an amplifying valve V with positive feedback supplied through tuned circuit X. Negative feedback is provided in the cathode lead by means of the reflected resistance in the primary coil of transformer T arising from the non-linear resistance R connected in the secondary circuit. The resistance R may be a metal filament lamp, the resistance of which varies as the current flowing. Fig. 4 shows an oscillator circuit in which feedback is supplied through .a Wheatstone bridge network having a resonant crystal C in one arm and a transformer T coupling the non-linear resistance element R in another armof the bridge. The bridge circuit is regarded as comprising a positive and a negative feedback path, the amount of negative feedback being controlled by non-linear resistance R. A proof is given that optimum conditions obtain when alphaR0Gia = 1, where alpha is the resistance/ current slope of the non-linear resistance, Ro is the effective value of the resistance at zero current, G is the mutual conductance of the amplifier, and ia is the output current, and the use of the transformer enables this equation to be satisfied. The transformer T should have a wide frequency response and minimum phase shift. The negative feedback connection may be taken either from the primary coil of the transformer, when the turns ratio n is proved to be 1 /< 3>#alphaR0Gia, or from the secondary when the turns ratio is given as 1 /alphaR0Gia.
