Title: Roll end withdrawal mechanism and motion picture projector
IPC: G03B1/56
Filed: 1971-10-05
Abstract: 1334783 Cinematography EASTMAN KODAK CO 5 Oct 1971 [5 Oct 1970 9 Feb 1971] 46313/71 Heading G2E A device for withdrawing the leading end of a film and applying it to an automatic threading device includes a member 30 having a hooked end 32 for engaging aperture 36 in film F. The member 30 is mounted on plate 62 see Fig.2. To operate the device handle 88 rotates shaft 84 clockwise causing torsion spring 90 to rotate plate 86 similarly. Pin 80 on the plate 86 therefore travels along slot 82 pivoting plate 62 anticlockwise against the action of spring 76 and bringing the hook 32 into contact with the film F. Film F is simultaneously being rotated in a rewinding sense on supply reel 22. When the film F and hook engage, the reel 22 is prevented from rotating and the pin 80 is pulled from latching notch 76c under the influence of spring 76 into which it moved when operation commenced. The spring 76 pulls the member 30 back to the position shown in Fig. 2 thereby leading the film F between driven and pressure rollers 40, 42. Alternative hook constructions are described. To maintain a loop between these rollers and the picture gate the film F is supplied at a faster rate than the gate requires, an excessive build up of film between the guides 106, 112 being dispersed by the film F pressing on the guide 106 and pivoting it about pin 108 so that the nip between rollers 40, 42 is relieved. When the film has been completely projected the film F pivots guide 112 (see Fig.7) about pin 114 so that the nip is relieved, a switch 148 closed to initiate film rewinding and an arm 150 also pivots guide 106 away from the film F by bearing against pin 152. The mechanism can also be used to stop the projector when projecting a film to rewind for a desired period and review the rewound section. This can be initiated by rotation of arm 182. For this operation a take up spool brake is provided at the non illustrated end of lever 130.

Abstract: 963,667. Wire enamelling ovens. GENERAL ELECTRIC CO. Dec. 18, 1962 [Dec. 27,1961], No. 47713/62. Heading F4G. A wire enamelling oven comprises a drying chamber formed of a solvent removal zone through which the wire 1 upwardly passes from an enamel applicator 2 through an entrance 3 past radiant heater panels 5 and in contact with a flow of air heated by a catalytic burner 7 and a further burner 8 and circulated by a fan 6, from which zone the wire passes to a curing zone through which it passes in counter-current to a flow of air heated by the burner 7 and circulated by a fan 19, the two air flows being removed through a common exhaust 15 situated between the zones to a mixing device 16 for combustion in the burner 7. The velocity of the air flows in the solvent removal zone and curing zone respectively are controlled by valves 12, 22 in ducts 11, 29 leading to the zones and the temperature of the air flows are controlled by thermocouples 9, 17a in the zones to regulate the burner 8 or admit cool air through a vent 10 to the solvent removal zone and admit cool air through a vent 18 to the cooling zone. The duct 11 has a curved end terminating in an air straightening grid 32 to cause the air to flow substantially parallel to the path of the wire. The radiant panel 5 is positioned at an angle to the path so as to increase the velocity of the air flow in the solvent removal zone, and a substantially constant or increasing velocity is achieved thereafter by including either a constant or decreasing cross-sectional area of the zone.

Title: Improvements in and relating to television display equipment
Inventor: TOPPING DOUGLAS RANDALL PETER
IPC: H04N7/10
Filed: 1966-10-25
Abstract: 1,145,167. Television. BRITISH RADIO CORP. (GOSPORT) Ltd. 25 Oct., 1966, No. 47884/66. Headings H4F and H4R. Equipment for use in a wired television distribution system in which any one of a number of signals may be selected by means of a selector switch and fed to a display device (and loudspeaker unit) that may be located away from the selector switch, comprises means for deriving a switching signal from received video signals when present, and means for applying such switching signal to cause the television display to be operative only when vision signals are being received. When a television signal is selected it is fed on lines 10 and 10<SP>1</SP> to display device and loud-speaker unit 11 and through a resistor 12 and capacitor 13 to the control grid of signal separator valve 14. Capacitor 13, resistor 18 and the diode action between the grid and cathode of valve 14 causes the video signal to be restored, the mean D.C. level 21 of which comprising the switching signal which is applied to the grid of valve 22 causing it to cut off. This interrupts the current in relay coil 23 and thus closes contact 24, 25, switching on the scanning and e.h.t. supplies to the CRT in the display device 11. Synch. signals 26 from the anode of valve 14 actuate the time base of the display device. The anode of separator valve 14 is coupled through diode 28 to the control grid of valve 29 having a relay coil 30 in its anode circuit. A resonant circuit 31 tuned to the line frequency of a 625-line signal is connected as shown and, when a television signal applied at 10 is a 405-line signal, acts as a short circuit to prevent any positive voltage from reaching valve 29 which is cut off. Relay 30 is thus released and contacts 32 are open, the equipment being arranged to display 405-line signals. When the signal is a 625-line signal, synch. pulses 26 are rectified at 28 and the resulting positive voltage which is smoothed at 33 causes valve 29 to conduct and relay 30 to operate, closing contacts 32. This energizes solenoid 34 which operates a switch 35, which switches the display device from the 405- to the 625-line condition. If the signal selected is a radio signal fed to device 11 on lead 36, i.e. in the absence of a television signal, a negative potential is not supplied to the grid of valve 22. Valve 22 thus conducts and operates relay 23 closing contacts 24 and 37 and opening contacts 24, 25 which conditions device 11 for radio reception.
