Title: Optical fibre splices and terminations
IPC: G02B6/38
Filed: 1978-12-20
Abstract: To make an optical fibre splice the two fibres to be spliced have the claddings removed from their ends, which are fitted into opposite ends of a tunnel between two blocks of a fluorinated or perfluorinated carbon polymer of co-polymer. This tunnel is defined by two grooves one in each block. The whole is clamped together so that at the splice region the cladding is replaced by the polymer or co- polymer, which also performs a light- guiding function in respect of light in the fibres.   The idea is also applicable to optical fibre terminations, and one is described in which the fibre is secured in a jewel-ended ferrule by a fused billet of the polymer or co-polymer.

Patent GB-2060305-A (GB)
Title: Acoustic wave device including a reflective array
IPC: H03H9/02
Filed: 1980-09-09
Abstract: In a surface acoustic wave reflective array of the kind in which parallel rows (4) of scatterers produce Bragg reflection of an incident wave in a wanted direction (X) at a given frequency determined by the row spacing, the rows (4) are formed of scattering centres, e.g. metallised dots (11), divisible into unit structures (10) each containing a group of at least two such centres, and the orientation and relative spacings (in terms of the Bragg wavelength) of the centres within each unit, relative to the direction (Z) of an incident beam, are such that the scattered waves constructively interfere in the wanted direction (X) while avoiding constructive interference in other directions. The scattering centres of each unit structure may be in the same row or in adjacent rows. No reflections are produced in unwanted directions, since the path difference for adjacent centres is then equal to 2a or one half wavelength, whereas it is zero for the direction (X). The scattering centres may alternatively be etched holes or non-conducting posts on the surface of the wave propagating medium, and the waves may be surface or surface-skimming bulk waves. <IMAGE>

Patent GB-808692-A (GB)
Abstract: 808,692. Cash registers. NATIONAL CASH REGISTER CO. May 17, 1957 [July 30, 1956], No. 15708/57. Class 106 (1). A key-set cash register having item-entering control keys and a total-taking key is provided with a device for signalling that the totalizer is clear, which device is electrically operated by means of a circuit including a switch so arranged that it is opened during each machine operation and closed at the conclusion of total-taking operations only. The machine described is adapted for multiple-item transactions and the signalling device is a lamp which is illuminated at the end of operations initiated by either A or B total-taking keys which cause the total standing on a main item totalizer to be transferred to a corresponding group totalizer on the same line and to a common grand totalizer on a second line. The lamp remains alight, until a further operation takes place, to indicate that a fresh multiple-item transaction may be commenced. The contacts of the switch 155 in the lamp circuit are urged to closed position by a spring 158 but may be held open by a lever 139 pivoted to the centre of a beam 137. One end of the latter is connected by a link 141 to an arm on the machine release shaft 118 which is rocked counter-clockwise in known manner during each machine operation. The other end of the beam 137 is coupled to a lever 130 positioned by a cam slot in a plate 126 controlled by the Row 1 differential mechanism, in turn controlled by keys including the A and B total-taking keys. Thus, during each operation, the machine release shaft 118 depresses the beam 137 sufficiently to open the switch 155 and, at the end of the operation, the lever 130 maintains the switch open except when the plate 126 has been positioned under the control of the A or B total-taking keys.
