Title: Generator device and method
IPC: H02N11/00
Filed: 1973-10-10
Abstract: 1448879 Free piston engines M DEMETRESCU 10 Oct 1973 [19 Oct 1972] 47314/73 Heading F1B [Also in Division H2] An internal combustion engine piston drives the inductor of a reciprocating electric generator (see Division H2) which is arranged with a spring mounting to form a mechanically resonant system, which oscillates at the resonant frequency between driving impulses from the piston. In the spark ignition system shown, each 4 stroke cycle of each cylinder a, b includes the injection of a fixed amount of fuel via solenoid valve 8. The cycles of the two cylinders are separated by one half stroke. After the power stroke, the resonant system of pistons 17, 18, inductor 19 and springs 46, 47 oscillates at the resonant frequency with an amplitude which decays exponentially at a rate determined by the load on the generator output plus any frictional losses. When this amplitude falls to a predetermined level (detected from the amplitude of the generator output) another four stroke cycle is initiated at the correct time in the oscillation, to sustain the oscillation. Thus, if the generator output is rectified to drive a D.C. motor for a vehicle, at idle i.e. zero required electrical output, there may be twenty complete oscillations of the piston between each four stroke cycle. Under full power, the power cycles are continuous Fig. 7 (not shown). Between the power cycles, the cylinders may be filled with clean air, to avoid pumping losses and to flush the cylinders thereby improving the combustion efficiency. A further embodiment Figs. 9-10 (not shown) shows a similar arrangement in a diesel engine.

An analogue-to-digital converter is calibrated by entering in a register a digital signal corresponding to each error to be corrected and the contents of the register are converted to analogue form and used as a correction signal. The zero corrector (25, Fig. 3, not shown) comprises an auxiliary analogue-to-digital converter consisting of a control circuit (27), a digital store (26) and a series of switches (28) each switching a weighted resistor (29) into circuit to provide a correction signal to the amplifier (19). To set the correction circuit the input (20) is opencircuited and the switches (15) of the feedback loop of the main converter are opened. Relay (35) is energized to close contacts (36), connecting the input to zero volts. The error signal from the comparator is then reduced to zero by the correction converter (25). A similar auxiliary converter is provided to balance the current input to the amplifier, to obtain a null comparator output when the input is opencircuited. There is also provision for making an automatic full-scale calibration. For this purpose a third auxiliary analogue-to-digital converter is provided which, when a standard calibration signal is applied to the main converter and the corresponding digital value entered in the register, controls the reference supply source to bring the error signal to zero.

Abstract: 1,198,435. Photo-electric dimension measurement. NATIONAL RESEARCH DEVELOPMENT CORP. Oct.20, 1967 [Oct.27, 1966], No.48183/66. Heading G1A. [Also in Divisions B3, G3] A machine tool includes a marker for following a profile of the workpiece at the rear of the tool, a device for comparing the marker position with a required position and controlling the position of the marker accordingly and a device for controlling the tool to follow the position of the marker. As shown, a workpiece 11 is machined by a tool 13 and the diameter, a short distance axially behind the tool, is followed by a front carriage 27 and a rear carriage 33 which, in a roughing and approach mode, are used as markers for a linear measuring unit 55, as disclosed in Specification 1, 143, 542, employing a moire fringe pattern technique. The output of the measuring unit is summated with a correction from a unit 57 and combined in a subtractor 66 with a desired workpiece diameter signal from an input 59. The resultant error signal is fed to an evaluator 63 and is used (1) to relatively position the carriages 27, 33 through a digital to analogue converter 69 and a lens servo 71 when the error is less than four thousandths of an inch and is used (2) to position the tool 13 and the lens servo 71 through a saddle control 25 when the error exceeds four thousandths of an inch. During fine machining lens units 47, 49 on the carriages are extended and light beams, shown dotted are projected on to a section 43R of a mark 43 on a photo-cathode of a television camera 39 whereby a digital count signal F-B, representative of the difference between the width F of the white area of the image 87 and the width B of the white area of the image 89 is derived which, through a digital to analogue converter 91, controls a centring servo 93 positioning the rear carriage 33 until the widths F, B are equal. An image of a mark 35 on the tool is projected by a lens 41 on to a section 43L of the mark and produces a signal T 1  -T 2  dependent on the distance of mark 35 off the axis of lens 41 which controls a fine servo 17 positioning the tool 13. The lens 41 is mounted on the front carriage 27 and is displaced in dependence on tool wear, by a servo 97 responsive to a sampling register 95 responsive to a signal F + B - (f + b) derived from the image on the section 43R of the mark, the signal #+ b being dependent on the widths of the dark areas. The signal F + B - (# + b) is recorded by a printer 99. In an inspection mode the front carriage 27 and the rear carriage 33 follow the edges of the workpiece and the lens servo 71 is controlled by the signal F + B - (# + b) via digital to analogue converter 69. The servo 93 is used for centring. The output of the evaluator 63 is then indicative of the difference between required and actual diameter of the workpiece and is recorded on the printer 99.
