Title: Improvements in and relating to visible indexes
IPC: B42F17/18
Filed: 1928-12-31
Abstract: 322,665. Power, R. F., and Morland & Impey, Ltd. Dec. 31, 1928. Sheet material, strengthening edges of. - The lower edge of an index card particularly for a visible index may be reinforced by a celluloid strip 30 formed similarly to the supporting-bar 3 of the card. The bar 3 comprises a strip of sheet metal folded and crossed longitudinally so as to irterlock with the edge of the card. In one form, Fig. 5, the strip 3 is folded on itself and a longitudinal crease 8 is formed therein with which engages a crease 9 on the card, which can be slid into or off the support without removing the support from the index-tray. The crease 9 may be dispensed with and the upper edge of the card folded over, the folded part being slid into the space above the crease 8. In order to reinforce the bar, a beaded edge 16 may be formed on one part 14 thereof and the fold 6 may be bent out of the plane of the bar. To form a stop to limit the movement of the card on the support, the two parts 7, 14 are pressed together near one end. A crease may be formed on the part 14 to coact with the crease 8. In a modified form, Figs. 8 and 9, the strip 3 is triple folded, a card-engaging crease 24 being provided on the inturned terminal part 23 and the front part 7 being formed with an inturned tongue 8 which holds the card against the crease 24. The part 23 may be extended to the top fold 6 or may be flanged over as shown at 28. A cut-away edge 11 on the part 7 facilitates the insertion of the card 1 and an end stop is formed by terminating the crease 24 and the, inturned edge 8 at the required point. A stamped-up tongue 26 facilitates manipulation of the bar and a triple thickness of metal is left at both ends to engage with the edges of the index tray. In another form of triple-folded strip, the crease is formed in the middle portion. Specifications 298,514. [Class 146 (i), Filing paper &c, sheets], and 322,666 are referred to.

Title: Magnetic integrator
IPC: H01P1/32
Filed: 1956-12-19
Abstract: 843,818. Circuits employing saturable magnetic elements. COLLINS RADIO CO. Dec. 19, 1956 [April 23, 1956], No. 38718/56. Class 40 (9). The number of pulses integrated by a hard magnetic core is detected by measuring the permeability of soft magnetic material in the flux path of the hard core, the pulses to be integrated being obtained from a clock-pulse source and being switched to drive the hard core one way or the other depending on the polarity of a control signal, rate of change of the detected permeability being subtracted from the control signal. The core construction used is shown in Fig. 1 where a core 2 of retentive material is wound with a centre-tapped winding 7 and has a flux path through yokes 5 and 6 and cores 3 and 4 of soft magnetic material; windings 11 and 14 being wound on cores 3 and 4. The integrating circuit is shown in Fig. 7 where the centre-tapped winding 7 is energized oppositely by clock pulses on terminal 31 depending on which one of gates 28, 29 is energized. A control voltage applied to terminal 25 opens gate 28 or 29 according to its polarity, an inverter 30 enabling the gates to be of like construction. The windings 11 and 14 on the soft cores are connected into a bridge circuit 33 energized, during times when centre-tapped winding 7 is inactive, by clock pulses taken over a delay circuit 32. As windings 11 and 14 change their inductance so that output of the bridge changes and this output is detected and filtered to indicate the degree of magnetization of the core 2, the output also being differentiated and subtracted from the control voltage in circuit 27 to equalize the effect of pulses on core 2.

Title: Apparatus for braking a motor vehicle handling trolley in garages and an electrical circuit for performing the same
IPC: E04H6/18
Filed: 1957-12-17
Abstract: 840,279. Handling trolley brakes. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. Dec. 17, 1957 [Dec. 22, 1956], No. 39151/57. Class 103 (1). An apparatus for braking a handling trolley for pushing and pulling vehicles into or out of parking bays in garages of the kind shown in Fig. 1 wherein the trolley has guide rollers d and entraining arms h, is characterized in that the brakes are automatically applied but the braking effort is arranged to depend upon the position of the arms h and hence upon the inertial load that must be braked. Referring to the circuit shown in Fig. 2, motors controlling the movement in or out of the entraining arms are controlled by push buttons 8 and 7 respectively. Contact elements 9 and 10 also controlled by the buttons 7 and 8 control contact pairs 13 and 14 of auxiliary relay 11 to select one or the other of the braking relays 15 and 16, the braking relay 15 short-circuiting about one third and the relay 16 about two thirds of the total resistance of the brake resistor 6. Assuming that the handling trolley has been pushed underneath a motor vehicle standing in one of the parking bays, button 7 is depressed to produce engagement of the motor vehicle. The depression of the button at the same time causes auxiliary relay 11 to operate, contact 14 to close and contact 13 to open so that braking relay 16 is siezed. Operation of relay 16 is by trip switch 17 which is closed by the trolley shortly before it reaches its terminal position in the elevator cage. The trolley loaded by the additional weight of the motor vehicle is therefore heavily braked.

Abstract: 1368997 Colour television TED BILDPLATTEN AG AEG TELEFUNKEN-TELDEC 25 Aug 1971 [27 Aug 1970 10 July 1971] 39776/71 Heading H4F Colour picture signals are recorded on a spiral track on a video disc so that radially adjacent track sections have recorded thereon chrominance modulated signals which are identical if the picture content is the same. The radially adjacent track sections may have recorded thereon signals derived from the same line periods of successive frames. A luminance signal may be recorded in a different frequency band from that of the chrominance modulated signals, or the luminance signal and chrominance modulated signals may be recorded line sequentially.  For recording NTSC signals the half-line offset (which causes a 180 degree phase change between the same line periods of successive frames) is removed. This may be done by delaying the signals by one line period, by using a 0/180 degree phase shifter to invert the signals in each second line-period or by changing the subcarrier frequency to be an integral multiple of the line frequency. A PAL signal may be similarly processed to remove the quarter-line offset, 25 Hz offset and PAL switching. On playback the offset may be restored or a reference subcarrier used for demodulation may be phase-switched as was the chrominance modulated signals prior to recording, so as to agree with the played back signals. For recording S.E.C.A.M. signals radially adjacent track sections have recorded thereon identical colour difference signals, a phase changer being used to remove the 180 degree phase change between the same lines of certain of the frames. For recording three-line sequential signals radially adjacent track sections have recorded thereon signals relating to the same primary colour (red, green or blue). If the chrominance modulated signals are recorded as frequency modulated signals, the phase and frequency of the recorded signals may be adjusted to constant values during each line blanking period in response to a control signal derived by comparing a reference frequency signal with the frequency modulated signal, this control signal being passed to a store which stores the control signal during the following line period.
