Title: Improvements in gramophones operatively combined with electric switches
IPC: G11B17/02
Filed: 1937-11-01
Abstract: 504,759. Interrupters. DEHN, F. B. (Automatic Instrument Co.) Nov. 1, 1937, No. 29860. [Class 38 (v)] [Also in Group XXXVIII] Relates to gramophones combined with switches for closing a number of circuits which effect operations such as lighting lamps or operating machines, during the playing of a record. According to the invention, mechanism actuated by the gramophone and adapted selectively to make contacts at frequent intervals (e.g. up to several hundred contacts during the playing of a record) comprises a commutator geared to the gramophone so as to be rotated a number of times, during the playing of a record, and a second commutator so actuated by the first one that it is partially rotated after each revolution of the first commutator. In the apparatus shown, an extension 5 of the turntable spindle of the gramophone carries a pinion 23 which gears with a wheel 13 adapted to drive, through a clutch 14, a shaft 10 carrying a commutator drum 8. A second commutator drum 9 is fixed on a parallel shaft 11 which is geared to the shaft 10 through Geneva mechanism so that on the completion of each revolution of the drum 8 the drum 9 is rotated through a fraction of a revolution. Each drum carries a spiral series of lugs 25 which, as the drums rotate, in turn press together corresponding pairs of insulated contact-fingers constituting switches 26, 27. These may be wired, as shown in Fig. 5, to any of the devices to be operated (diagrammatically shown by numerals enclosed in circles), and to a battery 45. In Fig. 5 the arms 30a, 30b represent those switches in the two series 26, 27 which are simultaneously closed at a particular time. With this arrangement, a number of circuits equal to the product of the number of switches 26 or 27 operable by each drum, is available. When a lever 19 is moved, either manually or by means of an electromagnet 24, to disengage the clutch 14, a spring 39 restores the drums to their initial position. Any suitable mechanism operated by an electromotor under the control of both manual and automatically operated switches may be provided for effecting repetition of the playing of a record, and such a motor may be associated with the magnet 24 so that the latter is energized only when the motor is running. A switch 70, opened when the magnet 24 is energized, prevents supply of current to any of the devices controlled by the commutators during the return movement of the drums under the influence of the spring 39.

Title: Photographic Camera
IPC: G03B9/08
Filed: 1966-07-13
Abstract: 1,154,913. Photographic cameras. EASTMAN KODAK CO. July 13, 1966 [July 19, 1965], No. 31468/66. Heading G2A. A photographic camera having an indexable socket for receiving flash-cubes and a cam 11 associated with the socket and indexed therewith, is further provided with means 10 for locking the cam and hence the socket against rotation, the means being unlocked to allow the rotation in response to sensing means 3 sensing the low scene light position of the movable needle 4 of a galvanometric device in the camera. For daylight operations when supplemental illumination is not required, the needle 4 is to the left (in Fig.) or in the centre of a slot 2 and depression of a shutter release member causes the slide 3 to rise until the needle 4 is clamped against the upper surface of the slot 2. The release member can continue its downward notion to trip the shutter. After exposure the film is advanced but the socket is not indexed as the cam 11 is locked against rotation. When the needle 4 is in the position shown (low scene light position), depression of the release member causes the slide 3 to miss the needle 4 and take up the position illustrated in phantom, thereby pivoting an extension 8 of a lever 5, 9. The arm 9 carries the locking means 10 which thus frees the cam 11 and socket for indexing. The arm 5 frees a slide 14 which moves to set the shutter at a speed suitable for a flash exposure. Switches 17, 19 are also closed by the slide 3 and the arm 5 respectively. Assuming an unused flash-bulb B is present, a light 23 is visible in the view-finder, and further depression of the release member trips the shutter and closes a switch 22 to fire the bulb B. As the release member returns to its normal position the slide 3 moves downwards and the lever 9 tends to return to the solid line position shown. A spring 10a prevents the locking means 10 reentering the same notch of the cam 11, so the socket and cam are indexing through 90 degrees when the film is wound on, the means 10 entering the next notch. If the needle 4 is in the position shown, but a flash-cube is not present, a switch 20 is closed. Consequently, when switches 17, 19 are closed, a light 21 is visible in the camera view-finder. If a used bulb is present in the flash circuit, the light 23 will not come on. There is further provided a cam 26 associated with the focusing mechanism. The cam closes a switch 25 to make a light 24 visible to an operator when switches 17, 19 are closed if the distance set is outside the range for which a flash-lamp is effective. A manual over-ride is provided to enable an operator to take fill-in flash pictures.

[Classes 79 (iii) and 79 (v)] Relates to a modification of the parent Specification in which, when the tractor-trailer are moving forward, a steering link actuated by the castor action of the front axle wheels of the trailer influences through the coupling rod the other steerable wheels of the trailer. As shown in Fig. 1 the front axle 6 of the trailer 4 carries wheels 8, 9 mounted for forward castor action and interconnected by steering arms 12, 13 and a track rod 14. The steering link 20 of the front axle 6 is interconnected with a steering link 18 of the rear axle 7 by the coupling rod 19. The link 20 is also pivoted to a rod 21 which is connected by a locking device 25 to a rod 22 pivoted on a pin 23 to the tractor 1 so that, when the locking device 25 rigidly connects the rods 21, 22, variation in the angle formed by the longitudinal axes of the tractor and trailer causes steering movement of the trailer wheels. In the modified steering arrangement shown in Fig. 2 the pin 23 is connected by links 44, 43, 41 to the steering link 18 of the rear axle 7. The locking device, Fig. 3, comprises a cylinder 28 connected to one rod and a member 37 having a fluid pressure inlet 38 and a hollow bore 36 connected to the other rod.
