Title: Improvements in and relating to Alternating Current Network Couplings
Inventor: THANAWALA HEMESH LAXMIDAS
IPC: H02H9/02
Filed: 1965-11-03
Abstract: 1,153,999. Coupling arrangements for A.C. networks. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 28 Oct., 1966 [3 Nov., 1965], No. 46556/65. Heading H2H. In a coupling arrangement for two A.C. networks of the type in which a series inductance/capacitance combination is tuned to resonance during normal operation and detuned upon abnormal (fault) conditions to limit the current flow, part or all of the combination is shunted by an auxiliary impedance which carries little or no current during normal operation and substantial current during abnormal conditions. The nature of the impedance can be resistive, inductive or capacitive or various combinations of these, and is determined by the characteristics of the networks and by the fault conditions likely to be experienced. For example, a resistive impedance will damp oscillations consequent upon a fault; a reactive impedance will influence the power factor during "settled" fault conditions and immediately following fault clearance, and can be made inductive or capacitive as required. In Fig. 2, the auxiliary impedance 7 is connected to tappings A, B on the inductance and capacitance portions 3, 4 of the resonant combination, these tappings being chosen so that the series L/C circuit so formed is resonant like the overall L/C combination of which it is a part. The detuning circuit comprises a saturable reactor 5 and resistor 6, but may be a switch by-passing the capacitor 4 or a portion thereof and comprising a spark gap, a vacuum switch or controlled semiconductor elements. Another saturable reactor may be connected in series with the auxiliary impedance 7 to keep its current negligible when voltage oscillations occur between points A, B during normal network operation. In other embodiments the impedance 7 is connected across the whole L/C combination 3, 4, Fig. 1 (not shown) or between a tapping on the inductance 3 and the reactor 5, Fig. 3 (not shown). The impedance 7 or parts thereof may be transformer-coupled instead of directly connected.

Filed: 1968-10-02
Abstract: 1275904 Sorting articles by means of endless conveyers ENGLISH ELECTRIC CO Ltd 2 Jan 1970 [2 Oct 1968] 46781/68 Heading B8A In a sorting apparatus in which articles 11 on a conveyer 10 are sorted by being discharged to selected conveyers 13 by the opening of an appropriate door MD1, MD2, &c., there are two memories, one M2 through which information is moved in synchronism with the passage of articles through the apparatus, and the other M1 containing fixed information representing the MD1, MD2 doors &c., and the two memories are repeatedly scanned to detect identity of information in corresponding locations in the two memories, such identity controlling the operation of the doors. The identity causes the information to be fed to a decoder 42 which selects the appropriate door or doors for opening or closing. As described, there is one main door MD1, MD2 &c., for each outlet, and auxiliary doors AD1, AD2 &c., between the main doors, each auxiliary door being operated for either of the two adjacent outlets. In the discharge of an article, e.g. a parcel as shown in Fig. 1, the auxiliary door AD2 (preceding the main door MD3), and the main door MD3, open together. Then as the parcel proceeds, the door AD2 closes and the auxiliary door AD3 opens. The destination of each parcel is recorded on a keyboard 30. Parcels passing the keyboard operator are monitored by a photo-cell 31. A device 20 produces a pulse for every 50 mm. of movement of the belt 10. The output of the device 20 and the photo-cell 31 are applied to an AND gate 33. The latter produces pulses which extinguish a light 35 for a predetermined period. The operator ensures that the next parcel does not move on to the belt before the light 35 comes on again. The keyboard information passes to a write register AMR2 of the memory M2. The pulses from the device 20 are also fed to a multivibrator 22 which feeds a scanning device 24. The latter is applied to the memories M1 and M2. The latter are fed to a comparator 40 which is connected to logic circuit decoders 42 and 43 via which operation of the gates is effected.

Abstract: 980,422. Stop motion for winding machines. FR. METTLER'S SOHNE MASCHINENFABRIK A.G. Nov. 29, 1963 [Nov. 30, 1962], No. 47268/63. Heading D1D. A stop motion for a winding machine having a drum-driven spool, the drum and spool being mounted for relative movement as the package grows, comprises a photo-electric device operable when the drum or spool moves into a predetermined position, and means for stopping the wind in response to operation of the photo-electric device. A drum 5 with a helical traverse guide is driven from shaft 1 by friction-wheels 2, 3, 4. The spool is carried in arms 11 fast with a pivot 13 also fast with a sector 16 having a slot of adjustable width 18. On either side of the sector are arms 23 one carrying a lamp and the other a photo-electric cell. As the package grows, the pivot 13 is rocked and the sector moves towards a position where the beam from the lamp passes through the slot and gives rise to a current which is amplified at 28 to energize a solenoid 29. When attracted, the armature 30 moves an arm 33 to lift the wheel 3 off the driving wheel 1. The critical position of the slot 17 is adjusted by rotating a shaft 21 to change the position of the lamp and cell relative to the slot, an indicator 35 being provided. Shaft 21 may be rotated by a worm and worm-wheel operated by a crank. In modifications, the spool support may be fixed and the drum carried by a pivotal or slidable support, in which case the sector is on the drum; the spool support may move parallel to itself and the sector move in a straight line; the lamp and cell may be on the movable support of the spool or drum in which case the position of the sector may be adjustable.

Abstract: 1,060,970. VHF/UHF band switching. R. HOPT. Nov. 23, 1964 [Dec. 18, 1963], No. 47539/64. Heading H3Q. In a VHF/UHF receiver a transistor 12 acts as preamplifier for both bands, and is coupled for UHF by a series capacitor 14 and shunt inductor 13 to a resonant line 22. A coupled line 16 passes the UHF signal to a frequency changer 5, and the I.F. output passes through a series-resonant filter 17, 18 to a transistor 19 which acts as I.F. amplifier. At VHF, switch 11 shorts the coupling inductor 13 and the capacitor 14 resonates with tuning inductors 20, 21 and the residual inductance of the line 22. The VHF output is taken from coupled coil 23 to transistor 19 which now acts as frequencychanger. The output from the UHF frequencychanger is then shorted to earth by switch 6. A further contact on the switch (not shown) connects the emitter of 12 to the appropriate aerial. The switch 6 and filter 17/18 may be omitted, and a further capacitor may be connected across the coil 20.

Title: A photographic printing and processing accessory for a projection film reader
IPC: G03B27/30
Filed: 1962-12-18
Abstract: 1,030,860. Photographic printer-reader apparatus. EASTMAN KODAK CO. Dec 18,1962 [Dec 18, 1961], No. 47827/62. Heading G2A. A microfilm reader has a printing and processing accessory which can be attached thereto, so that the image can be projected on to a screen for viewing, or alternatively reflected to fall on lightsensitive material in the accessory. As shown in Fig. 3, the reader itself comprises a viewing screen 21, a rear projection mirror 23, a lamp 31, a condenser system 29, a film gate 27, a magnification lens 179, and a projection lens 25. Thus an image of a microfilm F placed in the gate is projected on to the screen 21. The printer-processor accessory comprises a housing 11 of inverted L- shape, which can be mounted on the top and rear of the reader. The light-sensitive strip M is would off a roll 37, passes through a printing station 41 and a cutting station 43, then through a processing station 45, and finally between rollers 47, 47<SP>1</SP> to be delivered through an exit slot at the front of the apparatus. The printing station comprises a glass platen 51, against which the strip M is held in close contact by the weight of a pressure plate 53. The cutting station 43 consists of a fixed knife 61, against which a movable knife can be moved to sever the strip. The processing station 45 consists of an upper tray 71, a middle tray 73, and a lower tray 75. The print strip is passed between the upper and middle trays, where it is treated in a monobath solution pumped up from a bottle 35. Excess liquid drains into the lower tray 75, and is led back to the bottle 35. When the apparatus is being used as a projection reader, the rear mirror, which can pivot on a shaft 181, occupies the position shown in full lines in Figs. 3 and 4B. A further mirror 49, carried on a support 161 on a bracket 163, is raised to the position in Fig. 3, where it is out of the projection path, and also screens the sensitive material in the printing station from stray light. When a print exposure is to be made, the rear mirror 23 is tilted forward to the position shown in broken lines in Figs. 3 and 4B. The movement of this mirror is linked, by way of a bracket 187, lever 189, link 193, and a cam follower 197, to bracket 163. Thus mirror 49 is tilted into the position shown in broken lines in Fig. 3 (49<SP>1</SP> in Fig.4B). In this position, the image reflected from mirror 23 is reflected again from mirror 49 to the printing station 41, where an exposure is made. During the same series of movements, lens 179 is moved out of the light path so as to change the focus and magnification suitably. The various operations, i.e. mirror movement, severing the strip, conveyor drive, energization of the lamp, are automatically controlled by a multisurface cam 211.
