Guarding against unauthorized use. -The bonnet is locked and unlocked by electrically-operated means concurrently with the ignition system of the engine being rendered ineffective and effective. The bonnet 11, Fig. 4, is provided with a catch-plate 14 with which engages a bolt 13 operated by the core 12 of the locking and unloeking solenoids 8, 9. A key-operated switch 17, Fig. 1, energizes one or the other of the solenoids 8, 9 by means of the switch contact 24, the energizing current being supplied from the battery 19. Adjustment of the switch also by means of the contact 23 cuts off or supplies current to the low-tension circuit of the ignition induction coil 22. When ignition is by means of a magneto 25, an additional switch contact 28 earths the primary magneto circuit, thus cutting out the ignition when the bonnet is locked. As soon as the bonnet locking bolt has been operated a trip or change over switch 21 automatically breaks the circuit of the operating solenoid and closes the circuit of the other solenoid in readiness for the reverse adjustment of the switch and the reverse movement of the locking bolt. This change-over switch may consist of a spring contact 29 on an extension of the locking bolt 12 adapted to engage contacts 30, 30<a> in the circuit of the locking solenoid 8 or contacts 31, 31<a> in the circuit of the unlocking solenoid 9. A single solenoid with means for reversing the current may be employed. The solenoids may be replaced by electromagnets. The change-over switch may consist, as shown in Fig. 6, of a pivoted arm 33 carrying a relatively movable contact 32 adapted to engage the pair of contacts 31, 31<a> in one solenoid circuit or the pair of contacts 30, 30a in the other circuit, the arm being operated by the locking bolt, and a snap action being given by means of a spring 34.

Filed: 1933-02-24
Abstract: 396,319. Spinning and twisting machines. FILATURES BOUTRYDROULERS, 56, Rue Belle-Vue, Fives Lille, Nord, France. Feb. 24, 1933, No. 5715. Convention date, May 7, 1932. [Class 120 (ii).] Continuous spinning or twisting is effected in a mule by adjustably fixing the carriage I and providing the spindles with reciprocating ring rails 11. A thread guide 44 is so mounted that, when in the dotted position a for spinning warp, the yarn is led directly to the ring traveller, and, when in the position b for spinning weft, the yarn coils around the spindle before passing to the traveller. The plane of the axes of the drawing-rollers is substantially perpendicular to the direction of travel of the yarn. The rings are carried by holders 12, Fig. 3, so that by means of ears 13 they may be readily adjusted to the spindles. The tin roller 8 is driven from the rim pulley 9, and the backing-off clutch 37, 38 is utilized as a brake to stop the spindles quickly to prevent snarling, it being operated by a pedal 39 and levers 40, 41. The part 37 of the clutch when moved as above described also unlatches a spring- pressed lever which disconnects a clutch in the roller-driving gear so that the rollers stop before the spindles and the twist of the yarn is increased whereby doffing and restarting are facilitated. The building-motion comprises a lever 19, Fig. 2, operated by a cam driven from the drawing-rollers and connected by chains 28, 31 to a horizontal rod 33, which is thereby reciprocated and advanced and communicates the motion to the ring rails by chains 35 and pokers 36. The ratchet gear of the building- motion lever comprises a pawl lever 47 engaged by a fixed stud 48 so that the pawl is operated by the reciprocation of the lever. The ring rail is returned to its lowest position upon completion of the cops by operating a crank-handle 49.

Abstract: 542,309. Optical-projection apparatus. KODAK, Ltd. May 5, 1941, No. 5854. Convention date, May 3, 1940. [Class 97 (i)] In slide changing means comprising supply and take-up magazines 29, 30, respectively, at opposite ends of spaced plates 18, 24 having an exposure aperture 19, and enclosing a slide track and a slide changer 22 reciprocable to feed the slides along the track, a slide follower 33 in the feed magazine is positively advanced therein, in timed relation to the movements of the slide changer, to move the slides successively into the path of the changer; flexible connections may be provided to accommodate variations of width and thickness of the slides, an ejector may be provided to deliver the slides to the take-up magazine, and a shutter 116 may cut off the projection beam during slide changing. The magazines comprise rods 31, 36 and end plates 37, the rods of the take-up magazine being detachable 'from the plate 18. Slide changing is effected by rotation of a handle 42 secured to a screwed rod 41, and the rod 41 carries a nut 76, connected by a pivotted spring-pressed arm 79 to a rod 82 projecting from the follower 33 ; the screw and nut thus positively advance the follower, and the connection permits operation with slides of slightly varying thickness. The screw 41 carries a crank 43 connected by a link 45 to a stud 46 on a frame 52 having upper and lower arms 49, 50, guided by brackets 51. A pin 54 on the frame 52 projects through a slot 55 in the plate 18 and is connected by a spring to the slide changer 22 ; the spring serves to accommodate variations in width of the slides. The ejector comprises projections 95 from a plate 91 pivoted on thumb screws 93. The plate 91 has a yielding connection with a plate 97 pivoted on the upper thumb screw and carrying a pin 106 engaging a cam 105 carried by the arm 49 of the frame 52. Feed movement of the frame 52 and changer 22 causes the cam to pass over the pin 106, and return movement causes the pin to ride up the cam surface and turn the projections 95 to eject the slide ; a spring-pressed catch at the bottom of the ejection aperture 68 prevents return of the slide to the aperture. The shaft 118 of the shutter 116 is carried by a plate 119 detachably secured to the lens plate on the front of a bellows extension 15 permitting focusing. The shutter is rotated by chain gearing 122 from a shaft 120 passing through the plate 119 and having a pin and slot connection 125 with the end of the screw 41 ; this connection prevents focusing movement from interrupting the shutter drive.

Title: Improvements in or relating to cathode ray oscilloscopes
IPC: H04N5/228
Filed: 1948-02-27
Abstract: 643,912. Cathode-ray oscillographs. DEPARTMENT OF COMMERCE, DIRECTOR OF THE OFFICE OF TECHNICAL SERVICES OF. Feb. 27, 1948, No. 5989. Convention date, March 29, 1946. [Class 37] The intensity of the electron beam is automatically controlled so that it is reduced during zero or low deflection signal periods and increased during large deflection periods. A cathode-ray tube 1 has its cathode 2 connected through a condenser 3 to earth and also through a resistor 4 to the cathode of a diode 6. The anode of the diode 6 is connected to the slider of a potentiometer 7 which is connected in series with a resistance 8 between a source of negative bias and an earthed terminal 11. The cathode of the diode 6 is connected through a resistance 9 to the anode of a diode 15, the cathode of which is earthed. The anode of the diode 15 is also connected to a terminal 10 through resistances 12, 13, the latter of which is shunted by a condenser 14. A sweep generator 16 applies to the terminal 10 a sweep signal having at least a portion of each cycle positive, this signal also being applied to deflection means 17 of the cathode-ray tube 1. During the positive portion of the cycle the diode 15 conducts and causes the condenser 14 to charge, the potential at the cathode 2 becoming more positive and decreasing the intensity of the electron beam. When the positive portion of the cycle ends, the diode 15 ceases to conduct and the terminal 10 becomes at earth potential. The negative potential on the condenser 14 is then applied to the cathode 2 and increases the intensity of the electron beam. The cathode continues to acquire a negative potential with application of a sweep voltage of increasing amplitude until the cathode of the diode 6 becomes more negative than the anode. The diode 6 then conducts and prevents further increase of negative potential at the cathode 2 of the cathode-ray tube 1. If the potential on the grid remains constant the electron beam intensity increases as the cathode becomes more negative. The maximum intensity may be adjusted by means of the potentiometer 7.
