Abstract: 604,047. Feeding sheets. LINOTYPE & MACHINERY, Ltd., and ROWLANDS, T. Nov. 22, 1945, No. 31455. [Class 100(i)] A side-lay for sheet-feeding devices in printing and like machines of the kind claimed in Specification 501,364 having means (operated by a Bowden wire or similar flexible coupling) for gripping a sheet by a gripper member 12 and moving it laterally of the direction of feed of the sheet is constructed with means for controlling the movement of the gripper 12 comprising a track consisting of a bracket 20 formed with fixed parts 20a, 20b, 20c, Fig. 7, and a pivoted 'track 23 normally maintained by a spring 26 in the position shown in Fig: 7. The position of the gripper 12 is controlled by a roller 15 on a lever arm 14 integral with the gripper arm 11, and as the gripper carriage moves to the right from its position indicated by dotted lines in Fig. 1, the gripper roller 15 moves over a horizontal track 20c, and then is engaged by an inclined part of 24 of the pivoted track 23 and the arm 14 is moved clockwise to raise the 'gripper. When the roller 15 reaches a gap 28 between the two tracks the roller moves up to the track 20c until it engages a track 20b thus permitting the grippers to close, and as the gripper car- 'riage moves to the left the sheet is registered against one or two pivoted stop members 31 as in Specification 501,364. The gripper is finally-moved to release the sheet by engagement of the roller 15 with the inclined track 21, and the pivoted track 23. is then pushed aside and the roller 15 inoves along the horizontal track 29. Sheet guides are attached to the stop members 31.

Abstract: 485,577. Photographic sensitive materials; colour photography. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Nov. 18, 1936, No. 31638. Convention date, Oct. 21. [Class 98 (ii)] Light-sensitive photographic material for the production of coloured images comprises a compound of the general formula R1(R2)NCO.COOMe in which R1 is an organic radicle containing a chromophore group, R2 is hydrogen or an organic radicle and Me is hydrogen or a metal. The metal may be silver, chromium, iron, mercury, or one of the alkali metals, or ammonium. Suitable compounds are the salts of oxamic acid, e.g. of o-nitro oxanilic acid. After exposure the metal is removed by a solvent, e.g. potassium cyanide in the case of silver or mercury, or water in the case of the alkali metals. The compounds may be formed into emulsions and several emulsions for different colours may be superimposed. The layers may also be treated with sensitizing dyes. The resulting images may be intensified, e.g. by diazotizing and coupling with an azo component, or reduced, e.g. with a sulphite solution or a ferricyanide reducer. In examples, (1) the oxamine derivative of mononitro-benzidine in gelatin solution is mixed with thiosinamine and silver nitrate and applied to paper. After exposure the paper is treated with ammonium persulphate and potassium cyanide giving a red image ; (2) the silver salt of 6 : 6<1>-dinitro-o-tolidine-dioxamic acid in gelatin is applied to paper. After exposure the material is treated with potassium cyanide giving a red picture; (3) the silver salt of 2 : 21-dinitro-benzidine-dioxamic acid is used as in example (2) to give a yellow picture ; (4) the silver salt of o- or p-nitrooxanilic acid is used as in example (2) ; (5) the ammonium salt of 2 : 2<1>-dinitro-benzidinedioxamic acid is applied to paper, exposed and washed with water giving a yellow picture. The anion part of the molecule may also form a body readily convertible into a dye.

Filed: 1975-07-29
Abstract: 1507901 Measuring density of air electrically NISSAN MOTOR CO Ltd 29 July 1975 [1 Aug 1974] 31656/75 Heading G1N Apparatus for determining the density of atmospheric air comprises a sealed bellows 10, Fig. 1 acting on a carbon pile resistor 12 against a biasing leaf spring 14. The resistance of the carbon pile 12 is inversely proportional to the pressure on it by the bellows and is therefore proportional to the the atmospheric pressure and density and inversely proportional to the ambient temperature. The negative temperature coefficient of the carbon pile increases the sensitivity of the unit with respect to ambient temperature variations. The carbon pile resistor may alternatively be a diode or transistor.

Title: Entertainment structures
IPC: A63G7/00
Filed: 1929-10-19
Abstract: 333,803. Giraud, A. J. A. July 8, 1929, [Convention date]. Roundabouts.-An amusement device comprises a rotating structure 4 (e.g. a spur ring) rigid with frames 3 to which are pivoted at 2 cars 1 running on wheels on the track, so as to swing out centrifugally as they rotate with the structure, the cars being oscillated as they rotate with the structure. The latter may be accelerated or retarded rapidly (e.g. by means of a very progressive clutch to the driving means) to swing the cars, and there may be locking and unlocking means to hold the car against swinging. Each car 1, Fig. 2, is connected at 7 with a spring 5 attached at 6 to the frame 3. When the structure is rapidly accelerated the cars oscillate and stress springs 5 which then oscillate them in the opposite direction. To lock the cars against swinging, each car has pivoted to it at 12 a link 11, which is pivoted at 13 to a sliding bar 14 or frame 3. When the car has swung sufficiently, a lug on bar 14 is locked by a latch 15 having a depending member 16. This latter, later, meets a cam 17 on the track and releases the car. Cam 17 is controlled by an attendant so that it may be removed from the path of member 16. A brake, operated by the passenger's foot, may assist the erratic course of each car.
