Title: Electric signal synchronising apparatus
IPC: G01S1/30
Filed: 1972-05-19
Abstract: 1321798 Automatic phase control FURUNO ELECTRIC CO Ltd 19 May 1972 [27 May 1971] 23689/72 Heading H3A Apparatus for synchronizing a reference signal d with a received signal c in the form of bursts repeated at a predetermined rate T comprises; a frequency divider/phase shifter 4 for dividing down the output of a fixed frequency generator 5 to produce the reference signal d, having the same frequency as that of the input burst c; a comparator 3 comparing the signals c, d to detect the phase difference; a memory 6 for storing the detected difference during the period T; means for producing a control pulse train which divides the period T into n parts, n being proportional to the detected phase difference; and means for adjusting the phase shifter 4, by 1/n of the detected phase difference at each production of a control pulse of the train. In the embodiment of Fig. 1, the control pulse train is produced by feeding the output from the memory 6 and a divided-down output e from generator 5 to a unit 7 which produces a train of pulses f having a pulse width dependent on the detected phase error. This signal opens gate 9 to pass pulses from generator 5 to a counter 10 which produces an output pulse each time it fills, to adjust phase shifter 4. The unit 7, Fig. 3 (not shown), comprises a counter (12) which counts the pulses passed by gate 9 and which resets a bi-stable (13) to close the gate 9 whenever the count coincides with that stored in memory 6. In a modification, Fig. 4 (not shown) the units 7, 8, 9, 10 of Fig. 1, are replaced by an adder (21) and accumulator (22) which adds the output from memory 6 to the accumulated count under the control of the pulse train e to produce the control signal for the phase shifter. As described the apparatus is used in an Omega receiver, the signal c being the bursts of one particular received signal frequency as gated out by receiver 2.

Title: Feedback controls for cycloconverters
IPC: H02M5/27
Filed: 1971-04-19
Abstract: 1352949 Control of cycloconverters GENERAL ELECTRIC CO 19 April 1971 [11 March 1970] 23746/71 Heading H2F In a cycloconverter having feedback from the output to the gate control circuits for the main converting element, the feedback is arranged to be reduced as a function of output current and power factor so as to reduce the likelihood of mis-commutation of the main converting elements when operating on loads of poor power factor. Fig. 1 (not shown) relates to a block diagram of a three-phase cycloconverter comprising six groups of three thyristors arranged to convert the varying frequency output of an aircraft generator 10 into a constant 400 Hz output. The gate circuits of the thyristors are controlled in dependence on the output from a three-phase reference oscillator which feeds gating circuits or modulators with control pulses, the phase of which is determined by feedback circuits which may provide voltage regulation, wave shape correction or to minimize D.C. components. Each phase may have a feedback loop 88 including a twin T filter 30 arranged to block the 400 Hz fundamental and, after combination with other feedback loops in an operational amplifier 90, is fed to a modulator (not described in detail) controlling a pair of antiparallel groups of thyristors. The Specification describes with the aid of Figs. 6 and 7 (not shown) that for a given power factor load, the graph of input current against output current reaches a minimum at approximately half load. A signal dependent on power factor can thus be determined by monitoring the input current by means of transformers 60, 61, 62, the outputs of which are rectified so as to provide a negative going signal across capacitor 67. At low power factors, this signal will be less negative than the reference voltage across a Zener diode 93 so that a corresponding signal will be provided at the collector of transistor 97 which is added to a further signal from the common point of rectifiers 72... 74 which is proportional to load current. Field effect transistor 76 is shunted across the feedback loop 88 and is arranged to reduce the feedback if the output current is 1À25 times the rated value at unity power factor and at progressively lower currents at lower power factors, reducing to 0À5 times the rated load current at the zero power factor. The reduction in feedback is stated to reduce the likelihood of mis-commutation of the main converting elements.

The particular unit shown is an IGFET arrangement providing an OR circuit from the common source 10 to the drain terminal 26, one leg of the OR circuit taking the form of a.three input AND gate. The gate electrodes 22, 23, 24, 25 overlie surface emergent portions of the substrate (not visible) and have their ends terminating at high conductivity anti-inversion regions 17 to ensure that all current between source and drain is under gate control. If, for example, it was desired to prevent signal injection to the drain from a source area such as part 11 of source 10, the relevant gate (16) could be kept shut by strapping it to the potential of one of the adjacent source or drain regions (i.e. 11 or 19). Such an arrangement is illustrated in Fig. 2 (not shown) for a single IGFET isolated from surrounding circuits by an encircling source region.

Title: Warp knitting machine
Inventor: LAMBACH FRITZ
IPC: D04B27/00
Filed: 1951-10-16
Abstract: 736,396. Knitting-machines. REINER, Inc., R. Oct. 16, 1951, No. 24066/51. Class 74 (2). The driving speed of a variable speed drive which continuously drives the rotatable warp beam of a warp knitting machine and which, in operation, is driven by the main drive of the machine, is automatically adjustable in dependence on changes in the tension of the warp yarns, so as to maintain a substantially constant tension in them. When the tension on the warp yarns 32 or 60 increases or decreases beyond a predetermined amount, the output speed of a stepless variable speed drive 58 or 80 is adjusted through mechanism linked to the tension bar 34 or 62, to restore the yarn tension to normal. The variable speed drives are driven by gearing from a shaft 86, in turn driven by the main camshaft 22. In Figs. 1 and 3, movement of the tension bars swings a neutralizing member 54 or 76 which normally disables opposed pawls 144, 146, or 176, 178 constantly operated through linkwork from face cams 130, 172 on the shaft 86 and ultimately allows one or other of the pair concerned to rack round the appropriate one of opposed ratchets 150, 154 or 180, 182, keyed to the variable speed drive adjusting shaft 56 or 78. The basic speed of each warp beam can be set by hand, in the first instance. An excessive change in tension will cause operation of machine-stopping switch 190. In Fig. 4, the pawls 176, 178 for the drive 80 are operated from an eccentric 196 on the cam-shaft 22, whilst in the case of the drive 58, the pawls 204, 206 are moved together, one way or the other, by linkwork from the tension bar 34 until one or the other moves beyond control of a fixed neutralizing member 198 and engages its ratchet. In Fig. 9 sufficient movement of the tension bar beyond the mean position closes the appropriate one of two opposed switches and so drives one way or the other a reversible electric motor 224, or 248, connected through worm and worm-wheel to the variable speed drive adjusting shaft; excessive change in tension again causes the closing of a machinestopping switch. In Fig. 13, movement of the tension bar adjusts the pistons 260, 262, 264 of a hydraulic regulator valve and so determines whether fluid from a pump shall flow through one or other of two hydraulic motors replacing the electric motors 224, 248 and the direction of that flow.

A tower crane, Fig. 1, having a base A and a tower B, with a cone-shaped slewing top Z 2  to which a jib D and counter-jib C are hinged, is erected by a single cable f which is also the hoising cable. The cable f passes from a winch F up the tower over pulleys 70, 10, through the trolley and load hook, along the underside of the jib and back over the top side, round pulleys H 1 , Hg to form a loop H and finally round pulleys M 1 , M 2  to a fixed front f 1 . When the cable f is wound in, the loop H shortens raising the counter-jib C. Further winding in raises the tower to a vertical position and with it the jib D, Fig. 3. During this movement the tip of the tower Z 2  pivots about its hinge P thereby relieving some of the tension in the cable. After the tower has been locked in a vertical position the cable f is paid out to lower the counter-jib to the position shown in Fig. 3, in which a roller-type counterweight OR is attached. Winding in the cable again now raises the jib to a horizontal position in which it is locked, and further winding raises the counterjib. Shortening of the ties 60, 63 may be necessary for this operation. The tower B may be telescopic. -
