Abstract: 1,022,184. Photographic type-composing. T. C. THOMPSON & SON Ltd. June 19, 1964 [July 19, 1963], No. 28577/63. Heading B6W. [Also in Division G2] Lines of type can be justified by reflecting them from a flexible mirror whose curvature can be varied. As shown, an unjustified line of original type a is reflected from an inclined mirror B<SP>1</SP> through a lens B<SP>2</SP> and on to another inclined mirror D. This is a metal or metallized reflecting strip which is supported at its ends in holders d, d<SP>1</SP>. The holder d is rigidly fixed, and the top holder d<SP>1</SP> is part of a linkage framework d<SP>2</SP>, d<SP>4</SP>. A screwed rod d<SP>6</SP> passes through holder d<SP>1</SP>, to which it is secured by collars d<SP>7</SP>. The screwed rod can be rotated for axial displacement by a nut d<SP>8</SP>, so causing the framework to pivot about pins d<SP>3</SP>. This results in a flexure of the mirror D into a cylindrical surface, either concave or convex towards the incident beam, so justifying the image of line a to any desired length. After reflection from mirror D the beam is thrown on to a photographic film or plate C<SP>1</SP>. Prior to this, the beam may be intercepted by a mirror B<SP>3</SP> and thrown on to a graduated inspection screen (Fig. 3, not shown).

Abstract: 506,912. Building shoe heels. BRITISH UNITED SHOE MACHINERY CO, Ltd., and CLARKE, T. B. Nov. 2, 1937, No. 29894. [Classes 17 (i) and 17 (ii)] A plurality of heel lifts are assembled together and a fastener is driven from a passage of a nailing mechanism of a heel building machine into the assembly, the fastener fitting the passage sufficiently well to restrain it from running laterally .to any substantial extent. The assembly is then compressed and both end portions of the fastener are deformed sufficiently to hold the assembly in compressed condition. Headless fasteners with elongated cylindrical shanks as shown in Fig. 2 or Fig. 8 may be employed, the passages from which they are driven being of slightly larger diameter than the shanks. Three fasteners may be inserted in a heel-shaped assembly of lifts in a mould of a heel building machine, e.g. of the kind described in Specification 420,293, to hold them in assembled position, after which the assembly is inserted between the dies of a heelcompressing machine, e.g. of the kind described in Specification 22839/02, [Class 17], which engage top and bottom faces of the assembly and clench the points of the fasteners on the attaching face of the heel and deform the recessed ends 25, Fig. 2, and 39, Fig. 8, into heads 29, Fig. 3, at the lower or tread end. The driver which drives the fasteners from the passages of the nailing mechanism is shaped to engage the recessed end portion of the nail and hold it central to prevent lateral running during driving. The die of the heel-compressing machine which engages the tread end of the heel may have shallow circular recesses 45, Fig. 9, to receive the lower ends of the fasteners at the beginning of the compression operation.
