A cigar or cigarette holder or stem of a tobacco pipe having a smoke chamber 22 to receive smoke from a source and a withdrawal chamber 56 for direct communication with a smoker, a variable orifice metering apparatus positioned therebetween and having pairs of metering orifices for positively and variably controlling the mixture of air and smoke that enters the withdrawal chamber and reaches the smoker, the air-smoke mixture being set by rotatable matching indicia on the outside of the smoking device that align a predetermined orifice pair and thus the air to smoke ratio, is characterized in that said variable orifice metering apparatus is arranged in a removable centre section 14. The device comprises a rotating index section 16 which includes a liner 18, the chamber 22, a smoke passage 40 and a blind hole 42. Resilient tabs 26 connect the index section 16 to the centre section 14 by engaging grooves 32 in a socket 28 formed therein. The centre section 14 also includes an orifice plate 29 provided with three diametrically opposed pairs of orifices of different size. A vent is formed between the index section 16 and the centre section 14 which allows air to pass between the two sections in the region of the blind hole 42. The pairs of orifices register with the passage 40 and the blind hole 42 respectively and allow varying percentages of air to smoke to pass to the chamber 56 on rotation of the index section 16 relatively to the centre section 14. Protuberances 34 on the outer surface of the end portion 24 of the index section 16 fit into holding indentations 36 formed on the inner wall of the socket 28 to serve as a detent mechanism for holding the two sections 14, 16 in any one of the six possible relative angular positions after rotation.

Title: Photographic camera
IPC: G03B17/42
Filed: 1962-09-11
Abstract: 973,053. Electrically operated camera mechanisms. AGFA A.G. Sept. 11, 1962 [Sept. 16, 1961], No. 34742/62. Heading G2A. In a camera having film advancing means and/ or shutter setting means operable by an electric motor, with a switch in the motor circuit, a first means is provided for holding the switch open in the idle position of the camera, a second means including a member of the shutter mechansim and operable during the shutter running down movement to maintain the switch open, the arrangement being such that on actuating the camera release, the second means is rendered operative (to keep the switch open), and then the first means is rendered inoperative, so that as the second means becomes inoperative again after the shutter has run down, the switch is closed to operate the motor, which itself breaks the circuit again at the completion of its running period. Fig. 1 shows one form of the mechanism in the rest position. The contacts 4a, 4b in the motor circuit are maintained open by a lug 6b of a lever 6 spring-loaded anticlockwise about a pivot 5. A lug 6a at the other end of lever 6 enters a recess 8a in a disc 8. Coaxial with disc 8 is a follow-up disc 10, coupled to disc 8 by a spring 11. Disc 10 is maintained against its spring-loading by a lug 2b at the lower end of the camera release 2. When this release is depressed, first of all a lug 2a pivots a member 16 to release the shutter. At the same time a pin 17 is moved counter-clockwise to pivot a lever 18 so as to bring a lug 20a against contact 4a. Further depression of release 2 brings it into contact with lug 6c of lever 6, pivoting the latter so that its lug 6b comes away from contact 4a; this, however, is still held open by lug 20a of lever 18. The pivoting movement of lever 6 also brings its lug 6a out of recess 8a, and since lug 2b has moved down out of contact with disc 10, the latter turns anti-clockwise till it abuts against a pin 8b on disc 8, in which position disc 10 covers up the recess 8a. When the camera release 2 is now liberated to return to its original position, member 16 and pin 17 also return to their original positions, together with lever 18. Retraction of this latter allows the switch contacts 4a, 4b to close, and energize the motor drive 9. This re-sets the shutter, via gear wheels 12,13 and a spindle 14, and also transports the film. In addition, it turns discs 8 and 10 a complete revolution anti-clockwise, bringing them back to the position of Fig. 1, and so re-opening the recess 8a to re-admit lug 6a of lever 6, the lug 6b at the other end of the lever consequently opening the switch contacts again to break the motor circuit once more. Fig. 2 (not shown) is a modified arrangement with only one lever, co-operating directly with pin 17 and a cam on disc 10.

Filed: 1927-12-30
Abstract: 282,831. Akt.-Ges. Brown, Boveri et Cie. Dec. 30, 1926, [Convention date]. Switches, actuating; clockwork actuation; retarding devices.-Energization of an electromagnet i causes a detent k to release a ratchet wheel h which then, under the influence of a spring a or other power drives a train of clockwork mounted on a lever o pivoted at d, the resistance of the clockwork train, which may terminate in a damping vane u, to the motion causing the lever o to move upwards into engagement with a stop n thereby bringing a wheel q of the train into engagement with a wheel v which thereupon rotates and raises a weight x which after a time interval actuates a contact device y. When the electromagnet i is deenergized, which may occur automatically when contact is made at y, the detent k engages and stops the wheel h but the clockwork train continues to revolve owing to its kinetic energy and so causes the lever o to move back into its original position against the stop m. The wheel v is thus set free and the weight x descends without retardation ready for the next operation of the relay. In a modification the retarding device is connected to the driven member v instead of to the intermediate driving member q.
