Abstract: 1,032,478. Alarm clocks. TAVANNES WATCH CO.S.A. Oct. 16,1964 [Oct.28, 1963],No. 42266/64. Heading G3T. 30 An alarm clock mechanism is provided with means for automatically stopping the mechanism after a predetermined run-down of the alarm train, and with manual means for stopping the mechanism arranged so that, if this manual means is actuated, the raising of the usual hour wheel by a cam to a reset position releases the manual means so that the mechanism is prepared for the next actuation. At the set time, projections 6, Fig. 2 (not shown) on the hour wheel 5 loosely mounted on a spindle 1, drop into notches 4 of the alarm wheel 3 which is fast with spindle 1. The alarm releasing lever 13,19 pivoted at 14 and biased by spring 16 toward the hour wheel 5, thus follows this wheel to move the part 19 out of the path of a part 23 of the alarm hammer 20 to release it for rocking in the plane of the movement. A stop 18 carried by the release lever 13, 19 simultaneously moves down to a position close to the surface of a stop wheel 9. A wheel 30 connected with the alarm barrel and alarm escapement then drives an alarm-controlling wheel 7 which is free on spindle 1. This controlling wheel has an arcuate slot 8 in which is engaged a pin 10 carried by the stop wheel 9 also loose on spindle 1, the pin 10 at the start being biased by a spring 12 against one end 31 of the slot 8. When the other end 32 of this slot meets the pin, stop wheel 9 is driven clockwise in Fig 1, from the position shown where a conical stud 11 is positioned just to one side of the part 18, to a position where this stud reaches the other side of the part 18 and raises it to shut off the alarm. Pin 10 has then re-engaged the spring 12 and is biased back to the position shown. The alarm can be stopped manually by a press-button 29 which moves a pivoted yoke 25 against a return spring 33 to a position wherein a conical stud 26 on the yoke passes beneath the lever 13 and raises it to the shut-off position, the yoke meanwhile being retained in this actuated position by its engagement with the lever. After a few hours the hour wheel 7 is raised by its cam projections 6 to the alarm restraining position whereupon the yoke 25 is released and returns to its original position. The mechanism is thus prepared for the next time release of the alarm.

Title: Photographic camera with a replaceable or exchangeable objective shutter
IPC: G03B9/22
Filed: 1970-09-07
Abstract: 1329017 Photographic cameras COMPURWERK GmbH 7 Sept 1970 [22 Oct 1969] 42733/70 Heading G2A A photographic camera is designed to accept interchangeable lenses which contain shutters either mechanically or electronically timed. The invention is described in relation to a single lens reflex camera in which upon operation of release 46, Fig.1, a catch lever 26 pivots to allow a control disc 18 to rotate under spring action to raise a mirror 14 and a cover flap 24. Pivoting of lever 26 also moves a pin 50 which engages a catch lever 52. Lever 52 is moved clear of claw 54a on a spindle 54 and allows, via a telescopic coupling, an operating ring 84, Fig.3, to rotate. Rotation of ring 84 closes diaphragm blades 76 to a preset aperture and closes shutter blades 74. A cam surface 84c on operating ring 84 moves a latching lever 92 to free shutter driving disc 88 which reciprocates blade ring 80 to thus open and close the shutter. The exposure time may be determined electronically by an RC timing circuit, in which case an energized electromagnet holds the shutter in the open position until the electromagnet is deenergized. Alternatively the exposure time is determined mechanically with a gear chain, ratchet wheel and rocker assembly. In the former event, the interchangeable lens is provided with a pin 138 for engaging a lever 70 so that an arm 70a thereof engages arm 66b of a slide 66 to prevent movement of the slide, In the latter event the pin is omitted, and operation of camera release allows slide 66 to move under action of a spring 68 so that an arm 66c thereof engages and holds an arm 58c of a lever 58. Lever 58 is coupled via a rod 60 to the mirror and cover flap moving assembly, and a nose 58b engages claw 54a of spindle 54 so as to prevent opening of shutter and diaphragm blades to their viewing position until the mirror and cover flap are moved to their viewing position. Lever 58 is released during electronic timing by energization of electromagnet 64 which attracts an armature 62, the energization occurring at the end of an exposure interval. In a mechanically timed exposure, the manual release of camera release 46 brings slide 66 back to its initial position to release lever 58. The electronically timed exposure is set by manual adjustment of a resistor or by a photoresistor.

Patent GB-433464-A (GB)
Abstract: 433,464. Making motor-vehicle mudguards. SMITH, D., Castle Iron Works, Peel Street, Wolverhampton. Feb. 15, 1934, No. 4962. [Classes 83 (ii) and 83 (iv)] Curving; drawing dies.-A roll - bending machine for mudguards and like sheet metal articles is adapted to curve a strip transversely by means of rolls and then by feeding against suitably shaped formers, which operate first on one side of the strip and then on the other, to impart longitudinal curvature to the strip in opposite directions. A strip B, Fig. 1, for a mudguard is passed into the machine through feeding-in rolls A, A<1> which start to curve the strip transversely. The rolls D, D<1> effect the final transverse bending prior to the strip passing through a drawing die adapted to curl the edges of the strip which is fed to a further pair of rolls E, E and on emerging therefrom encounters a former G which bends it longitudinally. The rolls E, E<1> maintain a heavy pressure on the region near the mid-line of the mudguard during the bending toward the open side of the latter. By upward movement of a hand lever M, the former G is rotated away from the mudguard through toggle mechanism J, and the former N, connected to the former G by a link Q, is brought into position to curve the mudguard in the opposite direction ; the pressure of the rolls E, E<1> is relaxed somewhat during this operation since the material of the mudguard has now to be compressed along the mid-line. To remove crinkling at the changeover of the bend the first and second pairs of rolls are removed and the mudguard passed through the machine with a stroker shoe in place of the second former N.
