Abstract: 963,468. Camera cable release connectors. N. KARPF, [trading as LINHOF NIKOLAUS KARPF KOMM.-GES. PRAZISIONS-KAMERA-WERKE]. May 29,1962 [June 24, 1961], No. 20665/62. Heading G2A. [Also in Division E2] A cable release connector comprises a pair of tong-like members which can be secured to the shutter housing, the tong jaws defining between them a recess which can accommodate the end piece of a cable release, the said end piece being retained in the recess by resilient means urging the jaws together. As shown, the connector is in the form of a tongs-shaped member having two jaws 6, 8. Jaw 6 terminates at its lower end in a tapered bushing 7 which fits into the connecting nipple 5 on the shutter housing. The other jaw 8 is pivoted, and biased by a spring 12 about this pivot. At their upper ends, the two jaws form a tapered insert opening for the en'd piece 9 of a cable release 10; as this is pushed in, jaw 8 turns against the spring loading, until the end piece 9 is in sufficiently far for shouldered portions 11 on jaws 6, 8 to drop in place behind it. The pin 13 which acts as the transmission element then extends downwards just into contact with the shutter release 14. The connector can be adjustably mounted on the shutter panel 1 by means of a nut and screw arrangement 15, 16.

Patent GB-187738-A (GB)
Title: Improvements in directional wireless apparatus
IPC: G01S1/02
Filed: 1921-08-05
Abstract: 187,738. Robinson, J. Aug, 5, 1921. Bearings, determining; signalling to or from aircraft; directive signalling.-Relates to receiving-apparatus comprising a main and an auxiliary coil aerial at right angles to each other, as described in Specification 134,560, the direction of arriving waves being determined by turning the coils until equality of reception is obtained for the two positions of a switch which puts the auxiliary coil alternately in series and in opposition to the main coil. Such systems enable an aircraft to be kept head on to a transmitting- station. If, however, it is desired to fly directly towards the transmitter, it is necessary that the fore-and-aft line of the aircraft should be headed into the wind, and the invention consists in providing means for giving an adjustable bias to one of the telephone readings so that the pilot may make the necessary allowance for drift while still steering by maintaining equality of signal strength. As shown in Fig. 1, a main coil 5 and a perpendicular auxiliary coil 6 are used, the coi] 6 being in series with the main coil 5 and reversed relatively thereto by means of a switch 8. The amplifier 9 and phones 10 are connected across a tuning-condenser 7 in the aerial circuit. Movement of the switch 8 connects resistances 13, 13<x> in shunt to the phones 10. These resistances are adjustable and may be calibrated to give the angle of drift. One or the other is employed according as the diift is to port or starboard, the other being cut out by a switch 16 or 16<x>. Instead of employing the biasing resistances 13, 13<x>, the sensitiveness of the amplifier may be cut down when the switch is on one side, or the aerial circuit may be de-tuned. In another arrangement shown in Fig. 2, a third receiving-coil 17, parallel with the main coil 5 is connected to the auxiliary coil 6 so as to reverse therewith. The coil 17 thus assists reception for one position of the switch 8 and hinders reception for the other position. The degree of the assistance or hindrance is determined by the position of the tap 18 and the sense by the position of a second reversing-switch 23. Instead of using this switch, the coil 17 may be extended as shown at 25 and the tap connection 18 made at either side of the fixed central connection 24. The tapping adjustment is calibrated to read in angles of drift. Instead of the variable tap, the extra aerial coil 17 may be shunted by a variable resistance or inductance, or it may be arranged in a separate circuit coupled inductively to the circuit of the auxiliary coil 6. The coupling is variable both in degree and in sense and the adjusting means is calibrated to read as angles of drift. An inductance 11 is provided to maintain the tuning of the main aerial circuit when the auxiliary coil or coils are cut out.

Title: Improvements in or relating to printing
IPC: B65H23/188
Filed: 1928-07-18
Abstract: 320,885. Mackley, A. H. July 18, 1928. Feeding webs.-Apparatus for use in feeding a number of newspaper webs in register with one another comprises a stroboscopic device for obtaining intermittent images of a series of spaced marks provided along the webs, variation in the relative position of the images indicating a departure from register of the webs. The connection of the register may be effected by hand or automatically. In one form, Fig. 1. a previously printed web 2 being associated with a web 1 as it leaves a printing-couple 4, 5 passes round a hand-controlled registering roller 10. A series of equally spaced marks are provided on the webs 1, 2 and are periodically illuminated by lamps 18 in a circuit which is opened and closed by a contact segment 14 rotating with the printing cylinder 5 and co-operating with a pair of contacts 16, 17. Stationary images of the marks are reflected from mirrors 19, 20, Fig. 2, and viewed through lenses 21, 22. The contacts 16, 17 are carried by an adjustable arm 15 so that the position of the image viewed through the lens 21 can be adjusted to fall upon a hair line on the surface of the mirror 19. A similar hair line is provided on the mirror 20 and when the webs are in register the image of the marks on the web 2 coincides with this hair line. Any advance or lag of the web can be corrected by a downward or upward adjustment of the roller 10. One of the contacts 17 is adjustable relatively to the other so that the period of illumination of the lamps 18 can be altered as required. Fig. 4 shows diagrammatically a modification whereby the adjustment of the roller 10 is effected automatically. In this form, the web 2 is provided with a series of pairs of marks, images b<1>, b<2> of which are caused to fall on a pair of light sensitive cells 24, 25 arranged in the arms of a Wheatstone bridge which includes equal resistances 26, 27 and a mirror galvanometer 28. When the webs 1, 2 are in register the images b<1>, b<2> fall equally on the cells 24, 25 and the Wheatstone bridge is balanced. If the web 2 creeps or lags, more light falls on one cell than on the other. Current then flows from a source 29 and the galvanometer mirror is deflected causing a beam of light to be directed on to one or the other of two other light sensitive cells 30, 32 also in circuit with the source 29 and in series with relay switches 31, 33. The consequent closing of the switch 31 or 33 causes current to flow from a high tension source 36 through windings 34 or 35, actuating switches to bridge contact 38 with 39 and 40 with 41 in the case of winding 34, and to bridge contact 42 with 43 and 44 with 45 in the case of winding 35. Current then flows from the source 36 to drive, in one or the other direction, a motor 37 geared to the registering roller 10.
