Title: Improvements in, or relating to, apparatus for winding paper, or other similar flexible strip material, into roll form
Inventor: BARKER CLIFFORD LEWIS
IPC: G03B1/02
Filed: 1950-06-22
Abstract: 716,109. Film-windng means for photographic cameras. WALKER CROSWELLER & CO., Ltd. June 22, 1951 [June 22, 1950], No. 15561/50. Class 98(1) [Also in Groups XVI and XIX] In an apparatus for winding flexible strip material, e.g. winding film in a photographic camera, particularly where an exposed part of the film is to be cut off, a cam is fixed to a driven spindle within a relatively rotatable cylindrical shell around which the material is wound, such that the leading end of the strip material may be fed through a slot in the shell periphery, the shell being held against rotation by resilient means until the strip is gripped between the cam and shell interior. As applied to a recording instrument of the kind wherein a paper strip 7, Fig. 1, is fed from a roll across a viewing apparatus where it is marked by a reciprocating marker 14 which thus produces a graphical record 15 of a variable factor on the moving strip, the end of the strip 7 is fed from a spool (not shown), by a shaft 10 bearing teeth at its ends. A spindle 18 is driven by a pulley 19. band 28, and pulley 27 on the shaft 10 in a manner permitting slip of the spindle 18, relatively to the shaft 10 which is driven by an electric motor through a speed reduction gear. The spindle 18 carries a cam 20, Fig. 9, having a small clearance between its periphery and the inside of a shell 21 rotatably mounted on the spindle 18, The end of the strip is fed along guide channels 5 and 6, Fig. 1, formed at the edges of a guide plate 1, such that the strip end enters a slot 22, Fig. 9, in the shell 21 and curls around the cam 20. the shell being held by studs 31 engaging an L-shaped plate 29 against rotation, until the shell is rotated due to locking action of the strip between the cam 20 and shell 21. Thus, the strip is wound upon the shell 21. The wound roll may be removed by reversely rotating the pulley 19 relatively to the shell 21. thus releasing the strip end, and then sliding the roll axially off the shell 21, an end slot 23 registering with the slot 22 being provided iri the shell 21 for this purpose. The cam shape may be modified, as shown in Fig. 10, especially for the purpose of securing strips of varying thicknesses by providing arcuate surfaces 32b.

Title: Improvements in or relating to the impregnation of porous solids with other materials
Inventor: TINGLE ERIC DRUMMOND
IPC: F16C33/20
Filed: 1951-07-02
Abstract: A bearing material comprises a solid non-metallic component of rigid porous material impregnated with polytetrafluoroethylene. The porous material may be porous carbon.  The impregnation may be effected by driving a colloidal suspension of plastic material into the pores of the said non-metallic component and subsequently removing the continuous phase of the suspensoid, e.g. by heating. A coagulating agent may be added to the suspensoid after it has been caused to enter the pores of the solid non-metallic component to facilitate the removal of the continuous phase, or alternatively a wetting agent may be employed.  The invention is applied to bearings and electrical brushes.

Title: Process for removing free phenol from tetra-aryl orthosilicate and heat transfer media obtained by the process
IPC: C09K5/08
Filed: 1949-06-20
Abstract: Tetra-aryl orthosilicates are treated to remove free phenols by mixing from 5 to 30 per cent by weight of an organic acid anhydride based on the weight of tetra-aryl orthosilicate with the orthosilicate, heating the mixture until the free phenols and the added anhydride combine to form higher boiling point compounds. The anhydride may be benzoic, phthalic, or succinic anhydride.  In an example 8 per cent by weight of succinic anhydride based on the weight of tetra-aryl orthosilicate is added to a tetra-aryl orthosilicate which is a trans-esterified phenyl-cresyl orthosilicate mixture containing approximately 60 per cent phenyl and 40 per cent cresyl (chiefly m- and p-cresyl) radicals by weight, the said orthosilicate containing approximately 6 per cent by weight of free phenols, and the mixture is heated for four days to raise the boiling point from 460 DEG  to 495 DEG  F.  The Specification as open to inspection under Sect. 91 refers to mixing tetra-aryl orthosilicates and organic acid anhydrides in any proportions for the above process. This subject-matter does not appear in the Specification as accepted.
