Title: Cine film-holding cassettes
IPC: G03B17/26
Filed: 1963-08-08
Abstract: 1,042,276. Cine cameras and cassettes. EASTMAN KODAK CO. Aug. 8, 1963 [Dec. 7,1962], No. 31316/63. Heading G2E. The cassette for insertion into an electrically driven cine camera as disclosed in Specification 1, 040, 966 is modified to allow for inadvertent wrong insertion of the cassette into the camera. A stop lever arm 121 is pivoted on the cassette body at 123 and has a lip 125 which is urged by spring 127 towards the leading edge of a lever arm when cover 23 is open. The spring 127 is lighter than compression spring 59 and does not prevent the initial positioning of sensing toe 95 by the supply film roll. Cover 97 has an opening 99 through which projects extension 128 of arm 121 whose limiting position, determined by the diameter of the roll, is maintained when the cassette is closed and pressure pad 89 bears against extension 128 and the friction over-comes the force of springs 59 and 127. Therefore, if the cassette is inserted into the camera or the inverted position, the lever arm is driven from its operative position when its knob 109 contacts the fixed stud on the camera body through aperture 107 as described in Specification 1, 040, 966 but arm 121 is not affected and remains in its limiting position. If the cassette is then removed the lever arm may return to its initial position against arm 121 thereby resetting the switch mechanism to prevent running the film off the supply spool. Alternatively, the spring 127 may be secured to the cassette body to give a clockwise bias to arm 121.

Title: Drive Transmission.
Inventor: SCHICK GEORG
IPC: F16D7/06
Filed: 1968-07-01
Abstract: 1,198,574. Positive clutches. G. SCHICK. 1 July, 1968 [10 Nov., 1967], No. 31351/68. Heading F2C. An overload clutch, for a dental instrument or the like, driven by a flexible shaft, comprises a driven sleeve 5, Figs. 3, 1, within which a pin 7 retains a compression spring 6, and a threaded member 9 which is driven by the pin 7. If the sleeve 5 is driven to the right the member 9 has a left-hand thread and vice versa. Thus, if the tool is overloaded the pin is forced out of engagement with a notch 8 against the spring 6, and, since the sleeve 5 continues to rotate, the member 9 is unscrewed from the sleeve. This allows the pin 7 to move to the end 14 of the slot 7<SP>1</SP>. To re-engage the parts 5, 9 a pin is inserted in the hole 16 after withdrawing the part 11 and by means of a wrench 18, Fig. 2 (not shown), the two parts are screwed up as far as they will go thus ensuring a constant force from the spring 6.

Title: Mowing machines
IPC: A01D75/30
Filed: 1975-07-28
Abstract: 1501689 Mowing machines RANSOMES SIMS & JEFFERIES Ltd 20 July 1976 [28 July 1975] 31513/75 Headings A1 (F, P) A gang mower comprises side cutting units 30 mounted directly on a frame 10 so as to support part of the weight of the frame, and a centre cutting unit 32 mounted on an arm 34 which is connected to the frame by a ball joint 36 providing universal movement of the arm. The arm extends forwardly of the ball joint and is biassed clockwise by adjustable tension springs 50 which increase the pressure exerted on the ground by the centre cutting unit 32. The tension of the springs is adjusted so that the centre unit bears 40% of the weight of the frame, each side unit bearing 30%, in order to give a more uniform cut when the machine is traversing undulating ground. The frame 10 comprises an A-frame 12 fixed at the top to a link 16 connectable to a tractor top link 86, and fixed at the bottom to a transverse frama member 18. The tractor lower arms 82 are attachable to members 20 fast with the transverse member 18. Each side cutting unit 30 is supported on the frame by means of a sleeve 56 fixed to the unit fitting over a shaft 60 fast with the transverse member 18, so that the unit can pivot about the shaft 60 to follow transverse undulations in the ground. The mounting arm 34 of the centre cutting unit 32 extends between frame members 22 which extend rearwardly from the transverse member 18 and carry the ball joint 36. The frame members 22 are connected to the upper part of the A-frame 12 by reinforcing struts 24. The forward end of the mounting arm 34 extends through an aperture in a plate 38 fixed to the transverse member 18, this arrangement limits the universal movement of the arm 34 about the ball joint. Movement of the arm 34 about a vertical axis enables the centre cutting unit to move laterally when the machine follows a curved path so that it can assume the correct position to cut the swath between the swaths cut by the side cutters. In order to accommodate movements of the transverse frame member 18 relative to the tractor to allow both side cutting units to remain in contact with the ground when the tractor moves over uneven ground, a short extra link 80 is inserted between each lower arm 82 of the tractor three - point linkage and its lifting rod 84. The link 80 allows movement between the dotted and full line positions shown without any movement of the upper end 88 of the lifting rod, which movement is therefore independent of the other lower arm 82. In an embodiment of mower having five cutting units, two further side cutting units are provided beyond the side units 30 and are mounted on the frame in a similar fashion to the centre unit 32. Specification 1437261 is referred to.
Patent GB-816209-A (GB)
Title: Trimethylolpropane
IPC: C07C31/18
Filed: 1957-10-09
Abstract: Trimethylolpropane is recovered from an aqueous solution thereof containing also sodium formate according to the process claimed in the parent Specification, wherein the trimethylolpropane is extracted from said solution by continuously passing droplets of the liquid solvent through a continuous phase of said solution.  Ethyl acetate is the preferred liquid solvent but other solvents, e.g. esters of alcohols containing 2-4 carbon atoms with saturated monocarboxylic acids containing 1 to 3 carbon atoms and butyl and amyl alcohols may be used.  The trimethylolpropane solution to be subjected to extraction may be one obtained as described in Specification 816,210 and may be given any of the preliminary treatments described therein. The solution of trimethylolpropane in solvent obtained by the extraction procedure described may be steam-distilled to remove the solvent and the residue vacuum-flashed to leave high-boilers as a residue; the distillate from the vacuum-flashing is fed into a distillation column, at a point near the top, and pure trimethylolpropane is recovered as a sidestream near the base of the column.  Alternatively the trimethylolpropane may be recovered from its solution by extracting this solution countercurrently with water; the resulting aqueous solution of trimethylolpropane is distilled and subjected to vacuum-flashing and further treatment as before.  In an example a mixture of water, sodium formate and trimethylolpropane, produced by reacting formaldehyde and butyraldehyde by the method described in Specification 876,210 is fed continuously into a packed extraction tower, which is charged initially with the crude mixture, at a point near the top of the tower.  Ethyl acetate is introduced at a point near the bottom of the tower and water is introduced at an intermediate point.  The ethyl acetate is maintained in the discontinuous phase, as dispersed droplets, except at the very top of the tower. From the top of the tower there is obtained a continuous extract stream comprising water, ethyl acetate and trimethylol propane. The extract is steam distilled to remove most of the ethyl acetate, evaporated at sub-atmospheric pressure to remove the water and thereafter distilled at sub-atmospheric pressure to obtain pure trimethylolpropane as distillate.
