Title: Synchronising circuit for a system comprising logical elements
Inventor: HASKOVEC JIRI STEPAN
IPC: H03K3/313
Filed: 1963-01-29
Abstract: 1,025,401. Controlled non-linear inductors. CESKOSLOVENSKA AKADEMIE VED. Jan. 29, 1963, No. 3603/63. Heading H3B. A logical system in which the digits 1, 0 are represented by the presence or absence of positive half-cycles of alternating current controlled by a saturable inductor, the output circuit of the inductor includes a four layer semi-conducting diode of the PNPN type having a voltage/current characteristic illustrated in Fig. 1 (not shown). When core 1, having been set to one direction of saturation by a 1 signal in winding 2, is reset to the other direction of saturation by a half-cycle of alternating current in winding 3 from terminals 5, 6, a high voltage induced in coil 4 is sufficient to break down the diode 14 and to permit the remainder of the half-cycle to be applied to the load 19. The voltage of the alternating current supply on terminal 5, 6 is itself insufficient to break down diode 14. If the core 1 is initially left in a re-set state by a 0 signal in winding 2, no break down voltage is induced and no alternating current is fed to the load 19. By means of an impedance 11 comprising a capacitor and a resistor, the phase of the current in winding 3 can be adjusted so that the voltage at point 15 reaches a maximum and the diode 14 breaks down at the beginning of the operating halfwave and the whole half-wave of voltage appears a terminal 12 without distortion.

Title: Improvements in and relating to gyroscopic apparatus
IPC: G01C19/38
Filed: 1930-02-04
Abstract: 348,517. Gyroscopic apparatus. BURNSIDE, W. and HEATLY, W. G., Admiralty Research Laboratory, Teddington, Middlesex, and DRYSDALE, C. V., Admiralty, London. Feb. 4, 1930, No. 3712. [Class 97 (iii).] In gyroscopic apparatus in which the directional indications of a hunting followup member are transmitted to an indi- - cator or secondary transmission, the hunt is eliminated or reduced by the inertia of an auxiliary gyroscope. In one form, Fig. 1, a gyroscope 1 having its axis of rotation horizontal is mounted on horizontal trunnions 2 in a gimbal ring 3 :mounted in vertical trunnions 4 in a main frame 5. The lower trunnion 4 is connected by a flat spring 6 to a member 8 which is caused to move by the compass repeater motor 9 in accordance with the movements of the follow-up member of the master compass. The upper trunnion 4 is connected through gearing 10 to a transmitter 11, which provides non-hunting transmission since the gyroscope 1 because of its inertia takes up the mean position of the minor fluctuations of the member 8. Electromagnetic means for correcting tilting of the gyroscope 1 which is slightly bottom heavy, comprise electromagnets 17 mounted on the member 8, the armature 18 being attached to the trunnion 4. A pendulum 12 pivoted on the gimbal ring 3 carries contact arms 13 adapted to contact with mercury cups 15 mounted on either side of the gyro casing so that when the gyro 1 tilts a circuit through an electromagnet is closed bringing into action a restoring torque. The equivalent of bottom heaviness of the gyro 1 or member 12 may be obtained by springs. In a modification, Fig. 3, the gyro 1 pivots on horizontal trunnions 2 in a half ring 23 which is rotatable in the vertical bearing 24 and carries the gear wheel 26 driving the transmitter 27. The top heaviness of the gyro 1 caused by a weight 28 on the top of the casing is neutralized by a bail 30 which is connected to the gyro casing by a pin and slot connection 22 slightly displaced from the vertical axis. The bail 30 pivots on horizontal trunnions carried by a half ring 29 pivoting on a vertical axis 32 and carrying a gear wheel 34. The latter is driven through a differential gear 35 by repeat motors 36, 37 controlled from the transmitter 27 and master compass respectively. The arrangement is such that when trunnions 31, 2 are in alignment the bail 30 acts only to correct tilting of the gyro 1. When the trunnions 31, 2 are not in alignment, the bail causes the gyro to precess to increase the displacement. The action of the differential gear 35 is such that if the compass and gyro 1 maintain the same azimuth the member 29 will follow the gyro. If, however, the compass azimuth be displaced from the gyro azimuth the member 29 will be displaced from the gyro in the opposite direction and the action of the bail 30 is to precess the gyro into line with the compass.

Abstract: 1388473 Winding filters KUNSTSTOFFVERARBEITUNG & SCHREINEREI DIPL. ING. ADOLF VOSS 26 Jan 1972 [2 Feb 1971] 3728/72 Heading B5A [Also in Divisions B1 and F2] A filter tube 1, suitable for use in fountains or wells, is made of synthetic resin, such as polyester, reinforced with fibres, e.g. glass fibres and comprises a plurality of helically disposed members 2 extending between webs 4 extending along the tube, and spaced apart by slots 3, and a thread 5 along the interior of the tube. Sections of any length can be cut off from such a tube; and the sections may then be readily interconnected by means of threaded nipples having extensions which may be screwed into the internal threads of the tube sections. The tube may comprise several layers 7, 8, 9, 10, (Fig. 3), of resin impregnated layers of fibres extending along the whole length of the tube in the members 2, and in the webs 4. Layers of resin impregnated fibre strands 11, 12, 13 are also provided in webs 4. The tube may be made by placing a collapsible mandrel 15 between the head and tail portions 28, 29 of the machine shown in Fig. 9. The mandrel 15 (Fig. 4), comprises an external thread 23 and a rib 24 which extends along the thread and has, on each turn of the thread, clearances 25, 26, 27 corresponding to the number of webs 4 to be produced. The rib portions between the clearances produce the slots in the finished tube. As the support 31 is moved along screw 43 the layer 7 from spool 32 is helically wound around the rotating mandrel. The annular support 33 is then moved along the stationary mandrel to lay the layer 11 from spools 35 longitudinally along the clearances 25, 26, 27 and to helically wind thread 14 from spool 38 mounted on rotating ring 37, around the layer 11. The process is then repeated to lay the subsequent layers 8 to 13 and threads 14<SP>1</SP>, 1411 to give the structure shown in Fig. 3. When the layers have hardened the mandrel 15 is removed from the tube 1.

Abstract: 643,108. Systems depending on two or more sources ; automatic control of voltage and current. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., STEVENS, S. A., DUCKITT, H., and ALLEN, R. C. J. Feb. 13, 1948, No. 4265. [Classes 38 (ii) and 38 (iv)] An automatic regulating system for a plurality of power units A-C, each comprising a rectifier 3 supplied from an A.C. source 5-8 through a transformer 1 and induction or other voltage regulator 2, supplying in parallel a common load circuit 4, includes (1) a balancing relay 13 for each source which maintains a predetermined load division between the units by acting upon the associated regulator 2 and (2) a general voltage control relay 15 which exercises an overriding control on the regulators collectively to correct deviation of the load circuit voltage from a predetermined value. Each relay 13 is of the induction type and comprises a voltage winding 14 energized from phase conductor 5 and neutral 8, and a current winding 12 energized from a current transformer 10 in phase 5. The secondary windings of the several current transformers are connected in series in a closed loop 22, 23 so that the relay windings 12 are un-energized when the load is correctly shared by the units. Upon departure from this condition, however, an out-of-balance current flows through windings 12 and the relays so actuate the regulators 2 as to apply the necessary connections. If the load circuit voltage deviates from a predetermined value relay 15 operates to effect an appropriate adjustment of all of the regulators 2 by allowing a suitably phased voltage to be injected into the closed loop 22, 23 by a transformer 36. To provide for optional manual voltage control of some or all of the sources, an alternative closed loop 30, 31 is provided in which the parallel connected balancing relay and current transformer windings of any one or more of the sources may be included by switchgear 16-21 associated with this source or sources, the current traversing the alternative circuit not being subject to control by the general control relay but being under manual control, e.g. by means 40-45 permitting adjustment of a variable alternating voltage which may be injected into the second loop.
