Title: Improvements in kinematographic apparatus for the performance of musical films
IPC: G03B31/02
Filed: 1921-04-09
Abstract: 161,538. Vische, C. April 9, 1920, [Convention date]. Score marked for synchronizing with kinematographs; metronomes. -Rel&tes to means for indicating to a musical conductor the time of music to accompany the projection of a kinematograph film. The time of music accompanying the taking of the picture, or accompanying a. preliminary projection thereof, is indicated on the negative or positive film by fitting the music stand with a key upon which the conductor beats the time, each depression of the key closing the circuit of an electromagnet which operates devices for puncturing the moving film or producing light marks thereon. A positive film is then prepared with holes corresponding to the punctures or light marks on the negative, or holes are formed in the punctured positive film to correspond with the punctures, and this positive film passes, during projection, over a drum fitted witl devices adapted to co-operate with each hole ir the film to close the circuit of an electromagne on the music stand, the armature of this electro magnet serving to beat time. As the picture is being taken, or during the preliminary projection the conductor beats the time on a key 34, Fig. 6 and thus operates against the action of a spring 38 a lever 31 the other end of which is raised to allow a spring 39 to operate a lever 35 and dip an adjustable contact 36 into a mercury cup 30 The circuit thus made energizes an electromagne to operate devices for puncturing the edge of the film moving through the camera or projector. The holes in the positive film corresponding to the punctures or light marks are each arranged cen trally of the nearest division line between con secutive pictures to correspond with centrally dis posed holes 46, Figs. 10 and 11, spaced the deptl of one picture along the surface of a drum 4( traversed by the film during projection. The drum is fitted opposite each hole 46 with a radial ly-moving pin 47 pressed outwardly by a spring 48 and controlled by a spiral cam 49. Each pin when disengaged from the inner end of the spiral is held in retracted position by the film unless ii comes opposite to a hole in the film, in which case it is moved outwardly by the spring 48 and through contacts 50, 51 completes a circuit which energizes an electromagnet 55, Fig. 2, on the music stand, causing the armature 54 to beat time on a sounding board. Each depression of the armature 54 is adapted to close a further circuit to energize an electromagnet 65, Figs. 16 and 17, whereupon the armature 66 turning on a pivot 67 pulls, on a hook 68 to rotate a toothed wheel 69 of an indicator 70 which registers the score of the music.

Abstract: 292,731. Grant, W., D. April 19, 1927. Subaqueous boring. - In a percussive subaqueous drill, water under pressure is delivered to the drill head either through the hollow drill rod, or through a separate pipe or a separate duct in the drill rod, and is withdrawn with the. detritus through the drill rod. In Fig. 1, a casing 7 is engaged with the borehole and a further casing 8 slides thereon and extends above water. The drill rod 5 is surrounded by a water, box 9 with valved openings 10, 11, 13 connected respectively to a pressure pump 17, an ejector 20 and a vacuum pump. Water under pressure is first forced into the borehole through the opening 10, and the debris is afterwards removed by means of the ejector or vacuum pump. In a further arrangement, water under pressure is supplied through a pipe leading down through the drill tube. and passes up through the latter to an orifice therein. In the form shown in Fig. 3, water is first supplied through a tube 21 to the borehole and is afterwards forced through a pipe 26 with an upturned end to remove the, cuttings; a double chambered water box may be provided. In a further arrangement drill tubes with two ducts are employed and in this form also a double chambered water box is provided. Alternate cutters 29 of the drill head project within the bore of the latter.

Title: Improvements in or relating to cation-exchange copolymers of the carboxylic type
IPC: C08F265/06
Filed: 1952-05-02
Abstract: Cation exchange resins are prepared by proliferously copolymerizing at least 70 per cent of acrylic acid or an ester thereof with up to 30 per cent of a polyolefinic organic compound and, when using the ester, saponifying to obtain a popcorn copolymer containing at least 70 per cent of acrylic acid.  The polymerization may be effected in bulk, solution or suspension and up to 0.5 per cent of a peroxide catalyst such as benzoyl, lauryl or stearoyl peroxide, t-butyl hydroperoxide or inorganic per-salts may be used.  The copolymerization is carried out at a temperature of 20 DEG  to 80 DEG C., in the substantial absence of oxygen, such as in an inert atmosphere, and in the presence of a seed of a similar or dissimilar proliferous copolymer.  Acrylic acid esters specified are the methyl, ethyl, n-propyl, iso-propyl, n-butyl, iso-butyl, sec-butyl, t-butyl, iso-amyl, cyclohexyl, octyl, lauryl, octadecyl, benzyl and phenylethyl esters. Polyolefinic compounds which act as popping agents are divinyl benzene, butadiene, isoprene, bimethallyl, biallyl, trivinylbenzene, dicyclopentadiene, dimethallyl ether and sulphide, vinyl allyl ether, diallyl maleate and 2-chloroallyl crotonate.  Saponification is effected by aqueous or alcoholic bases such as sodium, potassium and quaternary ammonium hydroxides.  Sodium salts may be converted to potassium salts by means of excess potassium salts and the sodium or potassium salts may be converted to acid resins with hydrochloric or sulphuric acid.  The products are insoluble in solvents which dissolve the normal copolymers.  They swell in water to form gelatinous suspensions suitable for use in sodium reduction therapy.ALSO:A therapeutic composition for the treatment of edema consists of an impalpable dispersion in an aqueous medium of an opaque, infusible, proliferous copolymer of (a) acrylic acid and (b) a polyolefinic organic compound in which the olefinic linkages are in the aliphatic portion of the molecule, said copolymer containing at least 70 per cent. proliferously copolymerized acrylic acid (see Group IV (a)) and being capable of exchanging cations. p
