Title: A device for an intermittent change skiving thickness in skiving machines
IPC: C14B1/14
Filed: 1962-11-20
Abstract: 947,034. Skiving machines. STROJOSVIT NARODNI PODNIK. Nov. 20, 1962 [March 13, 1962], No. 43756/62. Heading B4B. A device for changing the skiving thickness in a skiving machine provided with locking of the machine controlled by a pedal is characterized in that the pedal 1 is shaped like a bell-crank lever with one arm against the longer arm 3 of a two arm lever biased by a spring 8, the shorter arm 4 of which through a lever 5 determines the skiving thickness by controlling a materialsupporting roller 11 co-operating with a cutterroller 12. The machine is first locked at the normal skiving thickness, and after the resistance of the spring-biased lever 3, 4 is overcome by further actuation of the pedal the two arm lever comes into a second position corresponding to a predetermined skiving thickness. The first locked position is produced by actuation of a pneumatic or like distributer 6 controlling a piston 7, the normal thickness being determined by an adjustable screw 9. Further depression of the pedal overcomes the force of the piston, the second skiving thickness being determined by an adjustable screw 10.

The plate groups (not shown) of the cells are interconnected by hole straps 4 having terminals 5 joined by a connector 6, these terminals and connector being sealed in an aperture 8 in the cover 3 and to a partition 2 by synthetic resin sealing compound 9. The battery is intended for operation between extreme temperatures, e.g. from -40 to + 90 C., and due to the different coefficients of thermal expansion of the cover 3 and the lead connector 6 and terminals 5 there is a tendency for cracking to occur between their interfaces.

Abstract: 1,181,503. Valves. CONCENTRIC CONTROLS Ltd. 19 Jan., 1968 [19 Oct., 1966], No. 45374/66. Heading F2V. [Also in Division F4] A control valve for use in gas burning equipment comprises a conical plug valve 12 rotatably manually operable by a spindle 19, said spindle being formed with a cam surface 17 which when rotated from the valve off position allows a rod 25 to descend closing electrical contacts 30, 32, the relative distance between said contacts also being adjustable by a temperature sensor spaced from the valve. The sensor, containing an expandable oil, is connected via a tube 35 to a chamber 34 defined by a pair on ribbed discs. In the event of the sensor acting as a thermostat expanded oil will enter chamber 34 and cause a pin 37 to separate the contacts. The contacts are mounted on spring blades 28, 31 attached to a support 29. The setting of the thermostat may be varied by rotating spindle 19 after the valve 12 is fully open, said rotation tending to urge the contacts away from one another. A siting projection 22 prevents rotation of spindle 19 until it has been depressed. In a modification the spring blades are replaced by a non-resilient beam, springs urging the beam into contact with pin 37, and rod 25 into contact with surface 17.

Title: Selective signal amplitude detector
IPC: G10L19/02
Filed: 1962-12-04
Abstract: 986, 520. Indicating extremes of amplitude. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 4, 1962 [Dec. 7, 1961], No. 45737/62. Heading G1U. [Also in Division G4] In speech recognition apparatus an indication of local amplitude extreme in a number of frequency channels is provided by applying each channel to a transistor adapted to respond to a local maximum, the output of any transistor which responds serving also to inhibit response of at least adjacent transistors. The speech signal from microphone 7 is applied to band-pass filters 8a-8n the outputs of which pass to detectors 10a-10n giving D.C. amplitudes proportional to the square of the input amplitudes. These signals are therefore measures of the power in the corresponding frequency band. The curve of Fig. 2 represents the power in the different frequency bands, each maximum being accompanied by smaller peaks on each side, relating to harmonics of the maximum frequency. The circuit is designed to respond only to the main maxima and to ignore all or some of the adjacent peaks. The outputs from detectors 10a- 10n are each applied to comparator transistors 11a-11n which tend to conduct. When the transistor, say 11b of the channel having a maximum, conducts the potential at point 13b increases and exceeds the amplitude of the adjacent peaks. Through resistors 14a and 14b the potential of points 13a and 13c is also raised sufficiently to prevent the transistors 11a and 11c conducting. At more remote points 13d-13n the effect of the conduction of transistor 11b is more attenuated due to the successive resistors 14c-14n and more remote transistors are not affected so that other local maximum may be detected in the same way. Those transistors which conduct energize relays 17a-17n through second transistors 16a-16n The output, Fig. 4 indicates the local maxima. These are called the "formants" of the signal. A modification having two comparator stages for detecting more widely differing maxima such as the one at f6.
