Title: Improvements in jet devices of the injector or ejector type
IPC: F04F5/46
Filed: 1937-01-26
Abstract: 471,034. Injectors and ejectors. HONERT, A. VAN DEN. Jan. 26, 1937, No. 2292. Convention date, Feb. 8, 1936. [Class 71] In a jet device for gaseous or vaporous fluids, the driving jet enters a channel with two parallel sides and a curved side between them starting from the position of the driving-jet and deviating gradually from the original direction, and entrains fluid through a suction opening opposite the curved side. The combined fluid passage has the shape of a flat box, the internal width corresponds to the thickness of the driving jet, and the curved wall is one of the narrower side walls. The driving- jet from the nozzle s enters tangentially to the curved wall. If equal amounts of fluid are to be drawn in per unit of length of the suction opening c-d, the curve a-b should be a parabola. If the passive medium is a gas, the influx velocity may rise above the critical (sound) velocity. The entrance c-d will be a convergent -divergent one. The channel for the passage of the mixture may be bent cylindrically, the curved wall a-b taking the form of a helix of varying pitch. Similar jets may be combined as shown in Fig. 7, or arranged in series.

Patent GB-345404-A (GB)
Title: A method of mordanting hair or the like for the production of felt
IPC: D01C3/00
Filed: 1930-01-24
Abstract: Skins or hair are mordanted for the production of felt with metal compounds in combination with nitric acid and oxidizing agents acting independently with nitric acid, the metal compounds being in greater quantities than those required for catalytic acceleration of the action of the oxidizing mordants.  Compounds of aluminium, zinc, nickel, silver, copper, tin, zirconium, bismuth, &c., are suitable. As oxidizing agents, there may be employed, chlorates, perchlorates, permanganates, chromates, iodates, persulphates, and hydrogen peroxide; chlorates and persulphates being preferred since they do not discolour the fibres.  In an example, skin or hair is treated with zinc nitrate, nitric acid, and potassium chlorate.  The Specification as open to inspection under Sect. 91 (3) (a) states also that such metal compounds as are also insecticidal may be used in order to make the hair capable of being stored. This subject-matter does not appear in the Specification as accepted.

Title: Receiving Socket Assembly for a Photographic Still Camera
Inventor: CHARNEY MICHAEL
IPC: G03B15/04
Filed: 1966-05-12
Abstract: 1,154,173. Lamp-holders. EASTMAN KODAK CO. 12 May, 1966 [24 May, 1965(2)], No. 2526/69. Divided out of 1,154,171. Heading H2E. [Also in Division G2] A photographic camera (10) (Figs. 1, 2, not shown), having a socket assembly (15) for a flashcube (16) is further provided with means operatively connecting the film wind-means 14, 45-48 and the socket assembly to rotate a portion 28 of the socket and a received flashcube, the operative means comprising a rotatable socket cam 45 engaging the socket portion; indexing means engaging the cam to prevent it rotating the socket assembly when a flashbulb is in a position for an effective exposure; and slip clutch means to rotate the cam with the film wind until engagement of the cam by the indexing means. A flashcube is inserted in the socket so that the centre post (19) of the flashcube receives a stabilizing stud 33 of the socket, a pair of lugs (20) on the centre-post being engaged by the arms of a square hair spring 32. Insertion of a flashcube causes an ejection ring 38 and a bifurcated yoke 39 to be depressed (in Fig. 3). One leg of the yoke thereby moves a member (43) (Fig. 6, not shown), forming part of e.g. a shutter speed change mechanism or a diaphragm adjustment mechanism, to a flash exposure control position. An exposure is then made by depressing a release button 13. Immediately before operation of the shutter, a release lever 72 moves a metering lever 68 anticlockwise (Fig. 3) and thereby displaces a metering pawl 58 sideways out of engagement with the cam 54. The pawl is also displaced forwardly by means of a spring, thereby preventing reengagement of a lug (60) (Figs. 7, 8, not shown) of the pawl with the adjacent slot (57) of the cam. Similarly, the lug (63) of a latch lever (62) is also prevented from re-entering the slot (57). After exposure, the film is wound on to the takeup spool 45. As the film wind drive gear 46 is rotated, an integral clutch gear 50 rotates the socket assembly via gearing (51-53) (Fig. 6) until the cam 54 and assembly, have turned through 90 degrees. As the assembly reaches the limit of rotation, the metering pawl 58 and latch lever (62) engage the next slot (57). The cam and assembly are thereby latched against further rotation. Further operation of the film winding mechanism causes the friction clutch (gear 51- plate 52) to slip. The flashcube and socket assembly may be rotated manually relative to the cam 54. To eject the flashcube, a button 41 is depressed, thus pivoting the yoke 39 and causing the lugs (20) to move the arms of spring 32 apart. In another embodiment (Figs. 9, 10, not shown) the slots (57) are replaced by teeth (76) which engage a spring (77).

Abstract: 1,000,715. Printing apparatus. THOMAS BONAR & CO. (CANADA) Ltd. Jan. 21, 1964 [Jan. 21, 1963], No. 2655/64. Heading B6C. [Also in Division B3] A process for treating the surface of an article made from a polyolefin film 10 comprises the steps of treating the surface of the film to provide a layer 17 of modified polyolefin on the surface receptive to printing ink but of reduced heat sealability property, and abrading the layer to remove a portion thereof and to substantially restore the heat sealability property. The polyolefin film, which may be polyethylene, polypropylene, solid polymer or other olefin, or copolymers of these olefins, is used for articles such as bags, packages and wrappings. The layer of modified polyolefin receptive to printing ink is produced by flame treatment, in which a direct flame, heating element, hot air or the like is used to soften the surface of the film, the opposite surface being cooled, or is produced by electrical treatment in which the surface is exposed to a gaseous surface containing at least 0À01% by volume of ozone. The modified surface is then receptive to printing ink but has reduced heat sealability which is substantially restored by engaging the surface with fine sandpaper or a cylindrical brush 12 having wire bristles 14 for removing a portion of the layer. The peripheral speed of the brush relative to the surface is at least 50 ft./min., and preferably 285 ft./min., the brush having bristles ¢ inch long and about 0À005 inch diameter. During movement of the film relative to the brush, the brush may be disengaged from the area of film bearing printing. Both sides of the film may be brushed.
