Abstract: 694,419. Variable resistances. SYLVANIA ELECTRIC PRODUCTS, Inc. April 6, 1950 [April 16, 1949], No. 21692/52. Divided out of 694,364. Class 37. [Also in Group XL (c)] An adjustable potentiometer comprises a planar member of relatively rigid thin sheet dielectric material having a large dielectric constant, an electrically continuous resistive element of open ring shape supported by and in engagement with one planar surface of the planar member, and a conductive member movably supported in insulated relation to at least the major length of the resistive element and capacitively coupled thereto through the intervening dielectric material. As shown in Figs. 1 and 1A, the resistance element 10 comprises an open ring of graphite &c. coated on one surface of a member 11 of material of high dielectric constant, such as titanium dioxide ceramic, titanium dioxide magnesium titanate, or titanium-zirconium dioxide ceramic. The ends of the element 10 are connected to terminals 12, 13. A conductive member or slider 20 is mounted on a shaft 24 of insulating material and is insulated from at least the major part of the length of the element 10. The member 20 includes an arm 27 which is movable along the element 10 but spaced therefrom by the dielectric member 11, which provides capacitive coupling between the arm 27 and the portion of the element 10 opposite to it. The member 20 is connected to a terminal 30. The potentiometer is adapted to be used as a volume control in a radio receiver having an intermediate frequency transformer 35, Fig. 2, a diode rectifier 38 and an audio amplifier valve 39 with an input circuit resistor 40. The capacitive coupling between the movable arm 27 and the element 10 is indicated as a condenser 32 adjustably coupled to portions of the resistance element by a slidable tap. In a modification, Fig. 3, the resistive element 10 is extended beyond the terminal 12 and the terminal 30 is bent down and connected to one end of the element by a rivet 38. The portion of the element 10 between the terminals 12, 30 may form the fixed resistor 40, Fig. 2. The portion of the resistive element 10 which lies between the terminals 12, 30 may alternatively be placed on the upper surface of the dielectric member 11, and may have a different resistance per unit length than the resistive element 10. Fig. 4 shows a dual potentiometer wherein one potentiometer comprises a resistance element 101, slider arm 20' and shaft 24<SP>1</SP>. A ring 39 of dielectric material is fixed between the element 10<SP>1</SP> and the arm 20<SP>1</SP>.

Abstract: 1435012 Automatic film processor H F HOPE and S F HOPE 9 May 1973 22219/73 Heading G2X [Also in Division H2] In web transporting equipment, e.g. for automatic x-ray and other film development, a web is driven through the equipment by means of rollers and having means which are driven by the passage of the web through the equipment the means being so arranged that at certain times during the passage of the web through the equipment an electric motor is energized, the motor being used to drive a pump which supplies a fluid to the equipment. Equipment for processing a photographic film 40 comprises a rack assembly 10 which includes a plurality of rollers 16-22 for driving the film 40 through a developing bath and two rollers 42, 46 which constitute a nip 50 through which the film passes so that the rollers 42, 44 are rotated whenever a film is being processed. A shaft of the roller 42 is provided with  an extension 52 carrying a gear 54 which drives a control gear 56 and thereby a further gear 72. The gears 56, 72 respectively carry small magnets 62, 76 and which co-operate with normally closed reed-type switches 64, 78. Switch 64 is included  in an electrical circuit 80 comprising a timer motor 86 and a motor 90 driving a pump by means of which the developing bath may be periodically replenished. Initially current is supplied to the timer motor 86 from an A.C. source by way of the closed switch 64, the motor 90 being de-energized by the timer switch 88. The timer motor 86 drives a timer dial (not shown) to a stall position in which the contacts 92, 94 of the switch 88 are maintained closed. When the magnet 62 on the gear 56 rotates to a given position reed switch 64 opens momentarily which releases the timer dial so that contacts 92, 98 of the switch 88 close to energize the motor 90 which runs for a period set on the timer dial - e.g. 10-15 seconds. Thus the pump is operated to replenish the bath each time the magnet 62 reaches a position to open the reed switch 64. Reed switch 78 is connected in series with a lamp and is opened and closed by the magnet 76 causing the lamp to flash thereby indicating the passage of a film through the developing bath.
