Filed: 1936-04-07
Abstract: 473,336. Photographic cameras with range-finders. KODAK, Ltd., NAGEL, H., and SMITH, J. BENNETT-. April 7, 1936, No. 10229. [Class 98 (i)] In a photographic camera a cam carried by a member pivotally mounted on the lens panel or other adjacent relatively fixed part coacts with a projection on a rotatable focusing part of the objective mount, the focusing movement of said mount being transmitted through the cam and the member to cause corresponding adjustment of light deviating means of a range-finder applied to the camera. In Figs. 1 and 2, the bell-crank lever 21 pivoted to the lens panel at 20 carries a cam surface 22 engaging with a projection 19 on the rotatable focusing mount. The range-finder mirror 15 is pivoted at 17 and operated by the lever 18 which is held by the spring 28 in contact with the arm 24 of the member 21. The member 21 and the lever 18 can thus be separated for the folding of the camera. In Fig. 5 the type of range-finder used is that described in Specification 440,353. The range-finder mirrors are fixed and the lens 26 attached to the arm 24 is moved for adjustment purposes across one of the two beams of light entering the range-finder. Specification 457,137 also is referred to.

Patent GB-712787-A (GB)
Title: Manufacture of thioketo-piperidine compounds and salts and quaternary derivatives thereof
Filed: 1952-04-24
Abstract: The invention comprises thioketo-piperidine compounds of the formula <FORM:0712787/IV (b)/1> in which one of the substituents X1 and X2 represents sulphur and the other oxygen or sulphur, R represents an unsubstituted aromatic residue and R1 has the same meaning as R or represents an alkyl or tertiary aminoalkyl group, and salts and quaternary derivatives of such compounds when they contain a tertiary aminoalkyl group.  R may represent, e.g., a phenyl or naphthyl group, and R1 may also represent, e.g., a methyl or ethyl group, a dialkylaminoalkyl group, or an alkylene-iminoalkyl group such as a piperidino- or morpholino-alkyl group.  Such compounds may be obtained by converting functional thio-derivatives of 2-aryl pentane-1 : 5-diacids in which the aryl group is unsubstituted and which contain in the 2-position a radical as defined for R1, into their cyclic thioimides.  For example the pentane-diacid-mono- or di-thioamides or functional derivatives thereof may be subjected to intramolecular acylation, e.g. the thioamides may be treated with concentrated sulphuric acid, acetic anhydride, tin tetrachloride, boron trifluoride etherates, zinc chloride, aluminium chloride or mixtures of these substances.  Alternatively the products are obtained by reacting the functional thio-derivatives of pentane diacids with ammonia.  As a further alternative at least one oxygen atom in the appropriately 3-substituted 3-aryl-2 : 6-dioxopiperidine may be replaced by sulphur, e.g. by reaction with phosphorus pentasulphide.  Products which contain a tertiary amino-alkyl group can be converted to salts with, e.g., hydrohalic, sulphuric, phosphoric, acetic, oxalic, citric, methane-sulphonic or toluene sulphonic acids. They can also be converted to quaternary derivatives by reaction with reactive esters of alcohols, e.g. those of hydrohalic, sulphuric or organic sulphonic acids, such as alkyl halides, dialkyl sulphates or toluene sulphonic acid esters.  In an example: (1) 2 : 2-diphenyl-pentane diacid-1-monothioamide is heated with acetic and sulphuric acids to give 3 : 3 - diphenyl - 2 - thioketo - 6 - oxo - piperidine.  Reaction of the product with phosphorus pentasulphide in pyridine gives 3 : 3-diphenyl-2 : 6-dithio-keto-piperidine.  In further examples: (2) 3 : 3-diphenyl-2-oxo-6-thioketo-piperidine; (3) 3 - phenyl - 3 - ethyl - 2 - oxo - 6 - thioketo - piperidine; (4) 3 - phenyl - 3 - (b  - diethyl - amino - ethyl) - 2 - oxo - 6 - thioketo - piperidine are prepared by reacting the corresponding 2 : 6-dioxo-derivatives with phosphorus pentasulphide.  2 : 2 - Diphenyl - pentane - diacid - 1 - monothioamide - 5 - monoamide is prepared by reacting 2 : 2 - diphenyl - pentane - diacid - 5 - monomethyl ester-1-mononitrile in alcohol with ammonia gas and hydrogen sulphide.

Patent GB-782298-A (GB)
Title: Improvements in means for extraction of sheets for inspection during sheet delivery operations
Inventor: TIMSON ERNEST ARTHUR
IPC: B65H29/58
Filed: 1955-04-12
Abstract: 782,298. Sheet-delivery apparatus. TIMSONS. Ltd. April 9, 1956 [April 12, 1955]. No. 10478/55. Class 100(1) In apparatus for delivering sheets S on to a pile 4 by means of grippers 3 carried by a pair of endless chains 1, the sheets striking front stops 5 coincident with the front side of the pile 4, the front stops are movable to allow a sheet to be engaged by a pair of co-operating rollers 10, 15 whereby the sheet is extracted for inspection. As shown, the stops 5 are secured on a spindle 6 rotatable in fixed brackets, and carry extensions 7 having arms 8 pivoted thereon which support rollers 10. When the spindle 6 is rotated clockwise by means of a handle H, the stops 5 drop below the line P of sheet-delivery, and the rollers 10 contact a set of rubber-covered rollers 15 which are constantly rotated by gearing from the gripper transfer shaft 2, on which the chain wheels 'are secured. A sheet released by the grippers 3 now misses the stops, shoots along the flat surfaces 7a of the extensions 7 to the bight of the rollers 10, 15 and is thereby removed for inspection. The stops &c. are latched automatically, when the handle H is raised by the engagement of a pawl 14 with a tooth 13 turnable with the spindle 6. A cam 25, connected by a link 24 with the pawl 14, is then raised into the path of rollers on one of the chains 1, so that the next roller to pas by the cam 25 depresses the latter, and effects automatic disengagement of the pawl 14 and return of the stops 5 to normal position. A transverse series of suction nozzles (not shown) may control the rear ends of the sheets S, and means, including a Bowden cable, operable on the turning of the spindle 6 to lower the stops 5 may control a valve, to cut off the suction to the nozzles. In a modification, the rollers 15 are only driven when they are engaged by the rollers 10. In this case, a disc C is driven continuously from the shaft 2, and in the raised position, the rollers 10 press against the rollers 15 to force a further roller on the shaft 16, which carries the rollers 15, into frictional driving contact with the disc C.

Filed: 1976-03-16
Abstract: 1533922 Haymakers C VAN DER LELY NV 16 March 1976 [20 March 1975] 10549/76 Heading A1F Contra-rotating rake members each having a felly 18 mounting substantially horizontally extending tines 19 have crop guides mounted at the front where crop is fed between the rake members. In Figures 1 and 2 the guides comprise curved tubes 29 supporting rods 32 and further arcuate tubes 27 with rods 31 which are located above the respective rake member. The tubes are either clamped on to frame beams 11 and 1 from below or can be mounted above the beams to be vertically adjustable with respect to the frame. The tubes 27 are not necessarily rigidly connected to tubes 29 and may be separately adjustable. The guides may also be adjustable radially and tangentially with respect to the rake members. As shown in Figures 5 and 6 the guides are closed screens 51 which are pivotally mounted in bearing bushes 44 inclined to the vertical so that, on pivoting, the screens do not foul the rake tines. The guides are biassed into their operating positions as shown in Figure 5 by torsion springs 48. A pin 50 riding in a slot 47 allows vertical movement of the screens 51 to follow ground undulations. In an embodiment the screens are replaced by freely'rotatable wheels supported in vertically extending bearing bushes. The corresponding rods 60 of the crop guides in the arrangement shown in Figure 9 are formed from single lengths of rod bent into channel shape and secured to a support 62. The support is pivotally mounted at its forward end to allow upward movement of the guide.

Title: Improvements in or relating to solar stills
IPC: F24S10/60
Filed: 1953-04-17
Abstract: <PICT:0743539/III/1> <PICT:0743539/III/2> Solar distillation apparatus, suitable for the distillation of sea water, comprises a housing provided with a sloping, transparent upper cover and containing a sheet of capillary material such as a cloth which is disposed so as to be exposed to solar radiation passing through the cover of the housing, means for feeding distilland to the capillary sheet, means for collecting the condensate which forms on and runs down the inside surface of the cover, means for withdrawing residual undistilled liquid from the apparatus, and valvemeans for periodically rinsing the capillary sheet.  A tank 10 (Fig. 2) or large area is connected by piping 22 to a plurality of distillation units 12 which extend lengthwise in an east-west direction.  Sea water is pumped into the tank so as to maintain a depth of about 6 inches.  The surface of the water is covered with a thin layer of dark petroleum oil or other heat-absorptive material 18.  By these means the water in tank 10 is preheated by solar radiation.  The flow of preheated water to the distillation units is controlled by valve 24.  The housing of each distillation unit 12 is made of concrete or resistant wood; and has a low southerly (N-hemisphere) wall 32 (Fig. 3) and a high northerly wall 34.  Sheets of a glass or of transparent plastic material 40 are supported on walls 32 and 34.  A sheet of black cloth 42 made of cotton, muslin or canvas, impregnated with copper naphthenate to prevent fungus growth, is suspended between walls 32 and 34 by fasteners 44.  Capillary wicks 46, such as loosely-twisted strands of cotton, rayon or linen, hang downwards from sheet 42 into troughs 48 which extend longitudinally through the bottom of the distillation unit.  These troughs are kept filled with salt water by piping 22, and the wicks 46 raise the water to sheet 42, and keep it in a saturated condition.  The water on the cloth is rapidly heated to 70-80 DEG F. by the sun's rays, thereby maintaining a high concentration of water vapour in the air present in unit 12. The vapour-laden air impinges on the under surface of sheet 40 which is relatively cool, and so the vapour condenses thereon.  The distilled water drains by gravity into trough 50; and from thence via pipe 52 to tank 16.  The troughs 48 slope gently to a common pipe 58 which discharges, via valve 60, into waste-brine tank 14.  When, after a period of operation, cloth 42 is to be washed free of accumulated salts, valve 60 is closed and valve 24 is opened more fully to run in sufficient water to submerge the cloth 42, but not enough to flow into trough 50.  After an adequate soaking time, valve 60 is opened to drain the rinsing water out of the unit.  There is also described an embodiment wherein the evaporator-cloth is disposed in a nearly vertical position; and water is supplied, by wicks, to the upper end of the cloth.

Title: Improvements in and relating to the formation and employment of a photographic record of lights and shades capable of use as a transfer printing plate
IPC: G03F7/06
Filed: 1921-04-18
Abstract: 187,638. Marks, E. C. R., (Daylight Film Corporation). April 18, 1921. Developing and after-treatment; photo-mechanical printing-surfaces; kinematograph picture films.-A process of forming a photographic record of lights and shades capable, of use as a transfer printing plate comprises hardening portions of exposed emulsion adjacent the light affected content of a photographic emulsion with an agent adapted to harden the emulsion by reaction with the light affected content of the emulsion and with a controlling agent for said hardening agent, the relative proportions of the hardening and controlling agents being such as to control selectively the area of influence of the hardening agent but to an extent less than the complete neutralisation of the hardening agent. The hardening under control may be effected during development, or the positive may be developed before the hardening is effected. In the first type of process a developer may be used containing pyrogallic acid as the hardening agent and sodium sulphite as the controlling agent, in approximately the proportions 1 : 2. In the second type of process the hardening is effected by the action of potassium bichromate in the presence of the silver image, the controlling agent being sulphuric or hydrochloric acid. The unhardened portions of the colloid remaining may be removed. The printing surface formed comprises a great number of photographically formed, extremely minute, individual protuberances, which are distributed and grouped irregularly so as to represent photographic lights and shades, and these protuberances will absorb, take up or carry the dye or ink in a few seconds, and yield a fine grain point which can be enlarged without showing prominence. The process is used for producing copies of kinematograph films in monochrome or colours. Various alternative methods are described for carrying out the process, and formulµ for these alternative methods are given. An accelerating agent such as sodium carbonate may be included in the developer. The hardening may be done in stages. Processes involving bleaching and re-exposure and reversal of the image are described. Exposure may be effected through the base. Very thin emulsions may be used. Coloured emulsions may be used and exposed with light of complementary colour. Specifications 1436/81, 17773/89, 27957/08, 18965/11, 20555/12, 5100/15, 127,953. 135,477, and 172,342 are referred to. Reference is also made to the use of potassium iodide in the developing composition described in Specification 187,932, and to the methods of printing an unperforated film from a perforated film described in Specification 187,933.
