Title: Improvements in or relating to fiber optics elements
IPC: H01J29/89
Filed: 1968-12-17
Abstract: 1,248,456. Cathode-ray display tubes. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 17 Dec., 1968 [28 Dec.,1967; 20 Jan., 1968], No. 59968/68. Heading H1D. [Also in Divisions G2 and H4] A fibre optics element consisting of fibre bundles 1 and 2, a transparent body 3, a semireflector 4 and a full reflector 5, may be used, on coating the end face of bundle 1 with a phosphor 14, as the face-plate of a C.R.T. When using the C.R.T. to scan an object 12<SP>1</SP>, Fig. 11, the horizontally scanning electron beam is passed through bundle 1, semi-reflector 4 and bundle 2 to the vertically moving object, and the reflected radiation returned via bundle 2 to the semireflector whence it is reflected through body 3 to a photo-electrical converter to record the image. Irregularities in transmission of the fibres may be compensated by placing neutral density filters 19, or a negative film of the irregularities, adjacent the block 3. The full mirror 5 prevents scattered light from the object being transmitted to the fibre bundle 1. When using the C.R.T. to record an electron beam modulated by a video signal, Fig. 6, the object is replaced by vertically moving recording paper 12. In this case the fibre irregularities are compensated by pre-recording on the paper 12 the irregularities by a means of fillers or a complementary negative 15 and light source 16.

Title: Counting apparatus
IPC: B41F33/00
Filed: 1978-10-31
Abstract: A numbering machine having a row of print wheels (16) for printing a main code number, and a check digit wheel (44) for printing a check digit derived from the code number. Except when singularities occur in the relation between the code number and the check digit, the check digit wheel is advanced in step with the units print wheel; in the case of Figure 1 this is done by a pawl (50) which moves in step with the pawl (34) for the units wheel. When a singularity occurs in the said relation, a different amount of rotation of the check digit wheel is required; in Figure 1, this is achieved by releasing the pawl 50, and a backstop pawl (56), to allow the wheel to rotate backwards to an extent determined by one of a group of detents (94), under the influence of a spring (66). <IMAGE>

Patent GB-2044102-A (GB)
Title: Sectioning device for use in removing hardened casts
IPC: A61F15/02
Filed: 1979-03-08
Abstract: The invention relates to devices for removing casts such as plaster casts. Although devices including a serpentine or zig-zag cutting wire embedded in the plaster cast have been proposed, on extension of the wire into a linear configuration under tension; the resistance to extension by such a wire has not been controllable thus often resulting in the complete extension of the cutting wire before the cutting of the cast is complete. The invention seeks to overcome this problem by the provision of a carrier strip 12 which engages the serpentine or zigzag cutting wire, with alternate stretches of the wire on opposite sides of the carrier strip, and which controls the extension of the cutting wire to provide a satisfactory cut. The device can be used for removing plaster casts on human limbs. <IMAGE>
