Title: Improvements in or relating to a roll film photographic camera
IPC: G03B19/04
Filed: 1941-08-11
Abstract: 545,350. Roll-film photographic cameras. KODAK, Ltd. Aug. 11, 1941, No. 10189. Convention date, Feb. 10, 1941. [Class 98 (i)] A roll-film camera has a focusing objective mount connected by a separable coupling to a range-finder or focus-indicating means, or both, on the camera body, the point of operative engagement of the coupling being variable so that the focusing may be correctly indicated in relation either to the focal plane of the roll-film or to the focal plane of a cut film or plate carried by a detachable camera back, this plane being spaced from the first. As shown, the tube 18 carrying the lens is moved axially.for focusing by rotation of the ring 19 which engages it and a collar 20 on the camera body by threads of apposite hand. An arm 36 pivoted on a frame 34 secured to the rear end of the tube 18 carries a screw the head 37 of which engages, in the position shown, an abutment 33 on an arm 30 secured to a spindle 27 carrying a cam 25. An arm 24 bearing on this cam adjusts angularly one mirror 23 of the range-finder. A spring 26 connected to the arm and to a lug on a gear segment 65 fixed to the spindle 27 keeps the arm in contact with the cam, and also tends to rotate the spindle clockwise to retain the abutment 33 and screw-head 37 in contact. When the removable plate back 11 is in use the focal plane is at F<SP>1</SP> instead of at F, and the coupling between the tube 18 and the range-finder must be correspondingly adjusted. For this purpose a lug 16 on the cover engages an arm 49 and causes it to rock an angle member 45 mounted on a shaft 44 and engaging a notch in the arm 36, which is thus raised from the position shown so that it can engage a second abutment 43 on a link 40 which is pivoted at one end to the arm 30 at the abutment 33 and guided at the other end by a pin 42 engaging a slot. The distance between the abutments 33 and 43 is equal to the distance between the focal planes F and F<SP>1</SP>, so that the range-finder is now operated in correct relation to the latter plane. In order that the mechanism may not be damaged by an attempt to place the back 11 in position when the tube 18 has not been retracted sufficiently to allow the screwhead 37 to be raised behind the abutment 43, the arm 49 operates the angle member 45 through a yielding spring drive to a pivoted member 48 having a lug 51 engaging the member 45. The rotatable disc 60 of a focus indicator, which may be constructed as described in Specification 540,438, is operated from the gear segment 65 engaging a pinion 64.

Patent GB-1122468-A (GB)
Title: Diamines
IPC: C07C209/48
Filed: 1966-03-09
Abstract: Amines are prepared by ozonizing a compound of the formula RCH = CH (CH2)nCN, wherein n is an integer of from 7 to 11 and R is hydrogen, C1- 10 alkyl, C2- 8 alkenyl or C4- 8 alkdienyl, and subjecting the ozonized product thus formed to reductive amination.  The reductive amination may be carried out in a single stage but is preferably conducted in two stages, viz. a catalytic hydrogenation stage followed by reaction with ammonia in the presence of hydrogen and a hydrogenation catalyst. The ozonization is preferably carried out using ozone in the presence of a C1- 8 alkanol. When R is hydrogen the process yields a mixture of methylamine and a diamine; when R is alkyl the process yields a diamine in admixture with a monoamine ranging from ethylamine to undecylamine; when R is alkenyl the process yields a mixture of a monoamine and two diamines; and when R is alkdienyl the process yields a mixture of a monoamine and three diamines. Exemplified products are methylamine, propylamine, hexylamine, nonylamine, undecylamine, stearylamine, 1,3-diaminopropane, 1,9-diaminononane, 1,10-diaminodecane, 1,11-diaminoundecane and 1,13-diaminotridecane.

Title: Improvements in the extraction and separation of stalk from fired or dried manufactured tea and/or for grading tea particles
IPC: F26B17/26
Filed: 1952-04-25
Abstract: 695,939. Separating solid materials. ANDREWS, H. C. April 25, 1952, No. 10490/52. Class 117  For separating stalk from tea and/ or for grading the leaf particles, the tea is caused to slide along a vibrating table interrupted by one or more transverse gaps and/or having apertures and having raised portions forming valleys which provide paths along the table into which the stalks find their way and pass over the gap or gaps and/or any of said apertures encountered. The table, which is polished, may be horizontal or sloping upwards or downwards and the vibration may have a frequency of 1000 to 2000 cycles/min. with an amplitude of 1/32 inch. In the embodiments described the table is corrugated longitudinally with V-shaped or rounded corrugations the pitch of which is of the order of “ inch. The transverse gaps are graded in size so as to grade the leaf falling therethrough. in one embodiment, Figs. 1, 3, the bottom edge 2 of the upper inclined surface 1 is chamfered at an angle of about 40 to 45 degrees to the slope of the surface. The upper edge 6 of the lower inclined surface 5 is rounded off. so that a piece of stalk moving in a valley 7 in the upper surface 1 slides over the gap 13 to the surface 5, whereas some of the leaf particles pass through the gap. Space is provided to deposit the tea to be treated as a layer on the upper part of the surface 1 from a long narrow slit in the bottom of a feed hopper. The gaps may be made adjustable, Figs. 4, 5, (not shown), by forming the lower plate in two parts, one of which may slide over the other. In another embodiment, the upper surface 1b, Fig. 8, may be flat or corrugated and chamfered at 24 to form points 25 at its lower edge. The upper edge 26 of the lower corrugated sur. face 5b is below the level of the points 25 and has a vertical flange 27 depending therefrom. The surface curves downwards iF a flattened portion before reaching the general slope. In alternative arrange ments, Figs. 9 to 16, (not shown), both top and bottom corrugated surfaces are cut off square or chamfered at various angles at the transverse gaps. The transverse gaps may be replaced by apertures 42, Figs. 17, 18, in an otherwise continuous surface. The apertures may be at the tops of the ridges of the corrugations 43, as shown, or may be in the bottoms of the valleys 44. In these cases the stalk rides over the apertures through which the leaf particles fall. In a further modification, Figs. 19, 20, the gap between two parallel but displaced inclined surfaces 45, 46, is not continuous, being crossed by integral bridges 50 separated by apertures 49 and carrying the stalk from one surface to the next.
