Title: Improvements in or relating to roll film cameras
IPC: G03B19/04
Filed: 1943-02-03
Abstract: 563,306. Roll-film cameras. KODAK, Ltd., and NAGEL, H. Feb. 3, 1943, No. 1796. [Classes 97 (i) and 98 (i)] Means for locking the film-feeding mechanism of a roll-film or kinematograph camera when the film is exhausted comprises a feeler which is held in an operative position by a latch device when a film spool is to be inserted and is mounted on a rock-shaft which is moved axially by the spool during insertion to release the latch, whereupon the feeler is moved by a spring into contact with the periphery of the film roll. At the same time a finger forming part of the latch moves into contact with a member normally preventing operation of the film feed latch, this member being finally moved by the finger, when the film is exhausted, to a position in which it permits operation of the film-feed latch. The Figures show a camera for photographing X-ray screen images, in which the film is fed after each exposure by a down-stroke of a lever 9, as described in the abridgment of Specification 563,304. A film footage indicator comprises a feeler 47 carried by an axially-movable rock-shaft 48 and maintained in contact with the outer turn of the film on the supply roll R by the action of a spring 54, a pointer 69 on the shaft indicating through a window the amount of film. When a new spool is to be inserted, the rock-shaft is turned by a knob 49 so that the feeler 47 clears the spool flange and is maintained in this position by pushing it inwardly until a finger 51 on the shaft engages under a fixed pin 52. When the new spool is inserted, the flange pushes the rod 48 outwardly, releasing the latch 51, 52 so that the feeler 47 engages the film. As the film is wound off the finger 51 rises, and by engaging a pin 67 on a pivoted arm 63 gradually raises this arm until, when the film is substantially exhausted, an abutment 66 is moved clear of a latching lever 60 which is then moved by a spring 62 so that a hooked end 55 engages a pin 56 on the film-feed lever 9 and prevents its further actuation. When the rock-shaft is rotated by the knob 49 for inserting a new spool, as above described, a pin 57 on an arm extending from the shaft moves down a cam surface 59 on the lever 60 and restores it to the non-latching position. Specifications 549,194 and 563,304 are referred to.

Title: Improvements in door checks and closers
IPC: E05F3/02
Filed: 1920-01-20
Abstract: 138,098. Schmidt, J. C. Sept. 7, 1917, [Convention date]. Operating doors by springs; checks. - A door check comprising a friction brake controlled and augmented by pneumatic means is provided in conjunction with a closing-spring. The spindle 20 of the closing-spring 22 carries at its lower end, within the housing 1, a disk 19 pinned to a split brake ring 10, which can be expanded to engage the inner surface of the housing 1, during the closing movement of the door, by means of oppositely-acting pistons 4, 5 working in diametricallyopposite cylinders 2, 3 on the housing. Rods 6, 7 pivoted on the pistons 4, 5 are connected to a wrist-pin 17 on a lever 16, which is pivoted in the gap in the split brake ring 10 and carries a roller 15 adapted to bear against one or other face of the gap according to the relative disposition of the pistons. Check valves 8 are provided in the pistons so that there is no resistance to the opening movement of the door. Control valves 9 are provided on the cylinders, and are adjusted so that the first half of the closing movement of the door is controlled primarily by the reduced pressure in the one cylinder, giving a maximum resistance at the beginning of the stroke, the action of that cylinder gradually decreasing and being progressively augmented by the increasing pressure in the other cylinder, and the last half of the stroke being primarily controlled by the pressure in this cylinder; or the valves may be adjusted for substantially uniform resistance throughout the stroke. The friction brake is applied during the first part of the closing movement, and is released before the closing movement is completed, the final portion of the movement being retarded by the pressure cylinder sufficiently to prevent slamming. The housing 1 is split and the adjacent edges are clamped together by means of a screw-threaded bolt and a hand-lever, which can he adjusted on the bolt to compensate for wear of the brake band, and also to hold the door in any desired position.

Abstract: 1341722 Shipbuilding MITSUBISHI JUKOGYO KK 18 Jan 1971 [23 Jan 1970] 2338/71 Heading B7S A mass production shipyard includes plant for manufacturing hull blocks, the plant comprising a number of workshops and reception and discharge stations arranged around an area over which blocks and components may be moved between the shops and stations. At least one spare station is located adjacent the area so that a block or block components can be temporarily stored in the event that a subsequent shop or station is already occupied by a block or components. The arrangement allows blocks and their components to follow different paths and thus reduces the delays that are experienced with a production line system. As illustrated, a truck 1 1  moves components and blocks over an area 1 between component collection, fabrication and assembly shops 2-7, welding shops 8, finishing shops 9, coating shops 10, a station 11 for the discharge of completed blocks, and a spare station 12. The truck 1 1  may itself enter the stations and shops, or the truck may remain on the area 1 in which case drives installed on the truck push or pull components or blocks over tables, rollers or conveyers between the stations and shops and the area 1. Two trucks may move on the area 1 in which case means are provided for passing blocks between them.

[Class 97 (ii)] A navigational instrument for plotting and reading magnetic and true compass bearings or courses comprises an oblong transparent base plate A having grid lines and a circular aperture in its central position in which fits a rotatable circular disc G. This disc G is retained in place by lugs engaging the undersurface of the plate A and is provided with a central stud I upon which is rotatably mounted a larger disc R. Degree &c. graduations b, J are marked on the discs R, G and surrounding the disc R on the base plate is arranged an annulus C with a matt surface. The disc G is provided with a line N to indicate true bearings and the disc R with a line T to represent magnetic bearings. Slots D are shown in the base plate A. Deviations of the steering compass are marked on the matt circle C while variations are obtained by rotating the disc R until an arrow head V indicates the variations on the degree circle of the disc G, after which the discs G,. R are clamped together by the stud P. To obtain the true and magnetic bearings of any course the leading edge W of the plate A is laid along the course and the central discs held while the plate is rotated until the leading edge W coincides with a meridian. The bearings may then be read off directly.
