Title: Improvements in and relating to photographic cameras
Inventor: SAWADA HIDEO
IPC: G03B19/04
Filed: 1968-04-23
Abstract: 1,207,233. Photographic cameras. RICOH K. K. April 23, 1968, No. 19068/68. Heading G2A. An automatic film winding mechanism comprises a knob 10 which rotates a housing 1 through a ratchet 12, 13 to tension a drive spring 2 having one end connected to housing 1 and the other end to a shaft 4. A rod 14 is slidably mounted within shaft 4 and is coupled thereto and to a film spool by a pin 19 so that when spring 2 is allowed to drive shaft 4 spool 20 is rotated. To disconnect spool 20 for re-wind, a button 15 is depressed, which lowers rod 14 and thus disengages pin 19 from shaft 4 and spool 20. Rod 14 is latched in this lowered position by a spring-pressed crank 18 which is pivoted on a disc 9, rigid with housing 1, and which engages a notch 14a in the rod. When a new film is required to be wound, a projection 10b on knob 10 moves the crank from the notch and a spring 16 returns the rod. Housing 1 is surrounded by a spring 7 to allow it to rotate in one direction only. Gears 5, 6 couple shaft 4 to the shutter mechanism (not shown) enabling spring 2 to drive the shutter. Gear 6 co-operates with a governor (not shown), to prevent the film being wound too rapidly, and with an automatic stepping film winder (hot shown) which checks the film after the winding on of each frame.

Abstract: 497,101. Vehicle bodies. AUTO UNION AKT.-GES. July 9, 1937, No. 19147. Convention date, July 9, 1936. [Class 108 (i)] [Also in Group V] A vehicle body for automobiles &c. is formed from parts of pressed laminated artificial resin material in such a manner that the reinforcements and flanges on the parts project towards the interior of the vehicle and the joints formed by abutting flanges follow the course of useful or ornamental ribs. The material may comprise layers of paper with or without layers of fabric. The ornamental ribs may cover the joints to protect them from moisture and, in cases of short dividing lines, the joints may be inclined to a main plane of the body to provide room for fixing screws. The size of the parts is calculated according to the pressure available and large apertures are arranged to adjoin surfaces requiring heavy pressure. As shown, the body comprises a floor part 1, windscreen frame 3, and side parts 2 and 4. The wheel housing 7 may be formed integral with the part 4 or separately. The rear part 8 is divided down a central line. The roof 11 may be in one piece or divided along the rib 13. All parts are provided with flanges at their edges and additional reinforcing ribs 19 may be provided. The drip rail may be moulded with the side parts or with the roof.
