Abstract: 1,125,979. Photographic camera. INTERNATIONAL POLAROID CORP. Dec. 14, 1966 [Dec. 30, 1965], No.56022/66. Heading G2A. A photographic camera comprising means for positioning within the camera a photo-sensitive material which is coupled to a sheet having predetermined reflective characteristics, a light source positioned to illuminate the sheet when the photo-sensitive material is ready for exposure, a photo-responsive element facing the illuminated sheet, and means responsive to the photoresponsive element for signalling the readiness for exposure. As shown in Fig. 1, the sheet having predetermined reflective characteristics, is a leader tongue 20 projecting from a camera back 18 containing a film pack. The photoresponsive element 60 is surrounded by a coaxial glass prism which reflects light from a source behind the element 60 on to the tongue 20 which, when in position, causes a buzzer and/or lamp 8 to be activated. After exposure, the material is withdrawn by a manually operated withdrawal apparatus 32 comprising a primary carriage 34 and a secondary carriage 36, slidably mounted on guide rods 36, 38 and 44, 46 respectively. The primary carriage 34 contains a biased clamping bar which holds the tongue 20 against a wall of the secondary carriage 36 during withdrawal. A switch 92 mounted in the path of the withdrawal apparatus 32 ensures that the photo-responsive element functions only when the apparatus 32 is continguous with the tongue 20. The apparatus can be adapted for use in roll film cameras.

Abstract: 1305615 Rolling mills MORGAN CONSTRUCTION CO 3 Dec 1970 [5 Dec 1969] 57438/70 Heading B3M Roll changing apparatus, for moving a roll assembly between a position in which it is solely supported by the housing of a roll stand and a position outside the stand Fig. 3, comprises a wheeled carriage 20 which supports a roll assembly and is movable along two sets of tracks 22 and 24 arranged laterally of the stand. The tracks are set at different levels and each has ramp sections 64 or 66 at its ends. As the carriage is rolled into the housing, the wheels 42 and 46 of the carriage reach these sections, the carriage then being positioned fully within the stand, and the carriage drops slightly. This causes the lower chocks 18b of the roll assembly, and hence the whole assembly, to be supported on the stand 10 and no longer by the side frames 32a of the carriage. The carriage can be coupled to the stand when located within the stand by means of studs 70 which can be locked within holes 72 in the carriage. The carriage, together with the stand, can then be moved by a ram 52 (which normally moves only the carriage) so that the stand is adjusted laterally on rails 12.

Title: Delayed-action door closing device
IPC: E05F3/10
Filed: 1973-12-12
Abstract: 1450427 Spring door closers with fluid damping G K N-STENMAN AB 12 Dec 1973 [21 Dec 1972] 57685/73 Heading E2M [Also in Division F2] A spring door closer, of the type in which door shaft 4 provided with a pinion 3 drives a piston 6 within a fluid filled cylinder 5 against a closer spring 9 and a fluid channel 11 links both sides of the piston, is provided with means located in the channel which constricts fluid flow during an initial section of the door closing movement but which widens this constriction during the final portion of the door opening movement. As shown an adjustable valve spindle 13 has a conical end portion 13a which engages in a seat 14a in a slidable sleeve 14 biassed toward the spindle by a spring 16. When the door is opened the piston moves to the left from the door closed position shown in Fig. 1 expelling fluid firstly via channels 11c, lid then, as the piston covers lid, through 11c alone. In this final stage the fluid forces sleeve 14 to the right to widen the constriction between 13a and 14a (Fig. 4). For the first portion of the closing movement i.e. before the piston uncovers channel 11d fluid is drawn into the cylinder through channel 11c forcing the sleeve 14 to the left to narrow this constriction. The slow movement of fluid through this narrowed constriction delays the closing of the door until channel lid is uncovered and provides an alternative passage for the fluid. Final damping of the door occurs as the piston covers exit passage 11a and fluid must flow through a passage 11b regulated by screw 12. A plate 24 resting against a washer 23 provides a safety valve to relieve pressure should the door be closed too quickly, though this may be replaced by a ball valve (Figs. 5-8 not shown). Fig. 9 shows a modification of the constriction means in which the spring 16 acts on a check valve 25 which seats into the sleeve 14 and has a slot 27 for the restricted passage of fluid in its closed position. This check valve provides overload protection during the opening of the door, enabling a larger fluid flow to pass.

Ferric oxide free from manganese is prepared by heating a ferrous sulphate solution in an acid medium, and in the presence of an oxidizing agent and sodium or potassium ions, to a temperature such that a sodium or potassium iron oxysulphate is precipitated. This precipitate is washed and dried, and heated in an oxidizing atmosphere to obtain ferric oxide e.g. at 875-925 C. The oxidizing agent may be air, ozone or hydrogen peroxide, but preferably sodium or potassium chlorate is used, in which case the additions of further sodium or potassium ions (as hydroxide or carbonate) is not necessary. The following double oxysulphates may be precipitated: 4Fe 2 O 3 .6SO 3 .Na 2 O.7H 2 O (struetural formula given) and 3Fe 2 O 3 .5SO 3 .K 2 O. 5H 2 O. Reduction of the ferric oxide at 500-550 C. results in pure magnetite.
