Patent GB-964350-A (GB)
Title: Resin compositions
Inventor: FARRELL PETER JEFFREY
IPC: C08K5/13
Filed: 1961-01-12
Abstract: A thermosetting resin composition comprises a resin based on vinyl chloride or vinylidene chloride in admixture with an amine having more than one amino group in its molecule and/or an amide having more than one primary or secondary amido-group in its molecule, and a phenol which is not condensed with formaldehyde or furfural. The thermosetting composition can have a plasticizer for the resin included in it. The resin can be used in the form of a dispersion in a plasticizer in which the amine and/or amide and phenol have been incorporated. Such a dispersion constitutes a plastisol; the plastisol can be of the type in which substantially none of the resin is dissolved in the plasticizer or a portion of the resin can be dissolved. Another form of the composition can be prepared by first mixing together the resin and plasticizer on a heated mill.  The preferred amines are the alkylene polyamines H2N-(-CR2-CR2-NH-)n-H where R is hydrogen, methyl, ethyl or propyl and n is an integer 1 to 5, but other amines are mentioned. Mixtures of amines may be used. The amides may be derived from dibasic acids and ammonia or amines, the preferred acids being the unsaturated dibasic aliphatic carboxylic acids having a chain containing 10 or more carbon atoms in the molecule, e.g. dilinoleic acid and the preferred amines used to prepare the amides are the alkylene polyamines. Any phenol or phenolic derivative containing a hydroxy group attached to the aromatic nucleus can be used, e.g. phenol, o-, m- and p-cresol, orthohydroxy-acetophenone, orthohydroxydiphenyl, catechol, resorcinol, hydroquinone, pyrogallol, hydroxyhydroquinone, phloroglucinol, nitrophenols, chlorophenols and bromophenols. The resin may be polyvinyl chloride, polyvinylidene chloride or copolymers of vinyl chloride with a monomer copolymerizable therewith.  The preferred thermosetting composition contains a bentonite clay which has been activated with an amine. Pigments, fillers and stabilizers may be added. The thermosetting composition can be moulded by heating the composition at least at its surface to a temperature of at least 150  DEG C. in a mould until thermoset and then releasing the shaped article, e.g. a shoe sole (see Division B5) from the mould without applying excessive strain to the article while it is still hot.

Abstract: 712,344. Reflex photographic cameras. MEYER, F. Jan. 17, 1952 [Jan. 17, 1951], No. 1385/52: Class 98(1) In a mirror reflex camera having a direct vision viewfinder, a reflecting member pivotally mounted above a ground glass screen and when in use obscuring the viewfinder field, a pivotally mounted mirror within the camera casing reflecting the light passing through the objective to the ground glass screen for focusing the objective or to a photoelectric cell of an exposure meter, the parts are so arranged that on raising the mirror the reflecting member is swung out of the light rays passing through the direct vision viewfinder in order to observe the picture outline and that in moving the photo-electric cell over the ground glass screen the reflecting member is swung out of the light rays passing through the viewfinder independently of the pivoted mirror movement. As shown, the image of only part of the picture field reflected by the pivoted mirror 16 is formed on the ground plane face of a plano-convex lens 19 and is viewed for focusing by means of the eye lens 21 as an erect non-laterally reversed image due to a roofedge pentagonal prism 26 which obstructs the objective lens 22 of a direct vision viewfinder. To determine the exposure required, the photo-electric cell of an exposure meter is moved to cover the lens 19 and in so moving a pin 33 on its supporting arm 34 turns anticlockwise a pivoted lever 35 which engages a pin 36 on the mount for the prism 26 pivoted at 30 so as to move the prism anticlockwise and allow observation through the direct vision viewfinder which indicates the limit of the picture field. On withdrawal of the cell 32, the prism returns to the position shown. The prism may also be raised to clear the direct vision finder by depression of a button 45 on a shaft 44 supported by a spring 38 in a sleeve 39 which is urged out of the camera by a weaker spring 37. Pressure on the button 45 first moves the sleeve 39 inwards and so rotates clockwise against a stop 40 a lever 29 which engages a pin 31 on the prism mount and which is connected by a link 28 to the support for the mirror 16, simultaneously rotating both prism and mirror anticlockwise. Further pressure on the button compresses the spring 38 and moves a finger 41 on the shaft 44 sliding along a reduced portion of the shaft 43 into engagement with a shoulder 42 thereon depressing this shaft to release the shutter.
