Title: Coupling plastics clad optical fibres - by removing cladding from fibre ends, coating with metal and bonding the ends
Inventor: FOLTZER LAWRENCE EDWARD
IPC: C03C25/106
Filed: 1979-02-09
Abstract: Optical fibre having a core and a cladding layer, is terminated by removing the cladding layer from one end to expose the core and deposited a highly reflective metalic layer on the exposed core. An optical fibre splice can be formed by abutting two such core ends and engaging the metallic coatings (e.g. by soldering or gluing a metal tube in to the coatings) to maintain the cores in position. Method is used esp. for coupling soft plastics-clad optical fibres to each other or to optical sources and detectors. The metal coating ensures that transmitted light is still retained in the core and supplies the strength needed to maintain the core in position during coupling. Additionally low cross-sectional area, hermetic splices can be obtd.

Title: Expanding, self-tapping plug for fastening panels to concrete base - comprises tubular nail encasing dowel which is forced apart by driving expander into it
Inventor: APPELROS SVEN EMIL
IPC: E04F13/08
Filed: 1979-04-18
Abstract: A plug is claimed for fastening a cladding, e.g. an insulating panel, onto a light wt. i.e. low-density concrete base, the plug being adapted to be driven into, and anchored in, the base without a hole being previously drilled into the latter. The plug has a head and comprises a tubular slotted nail where one end forms the head whilst the other has a point to be driven into the base. Another component is a body which is forced through the tubular nail after the latter has been introduced into the base; this causing expansion and consequent secure anchoring of the nail. The inner cross-section of the nail is reduced by the forcing of it into the base. This contricted section is made of wood or plastics, e.g. PVC, and is expanded by driving the body which is of cylindrical shape with a point at its end, into it.

Title: Radio receiver with programme selection switch - addressing memories which store tuning signals and states of other circuits in receiver
Inventor: SCHROEDER ERNST DIPL ING
IPC: H03J5/02
Filed: 1979-05-30
Abstract: The radio receiver has a programme selection switch selecting tuning signals stored in a memory. Other memories store the operating states of other subassemblies in the receiver and are also addressed by the selection switch when the tuning signals are selected. The operating states stored in these other memories are the state of the stereo decoder (mono/stereo) a dynamic-range expander (on/off) and a noise suppression circuit (on/off). The advantage lies in making it easier for the user to obtain the same conditions when he selects a programme for the second time - i.e. the parameters are the same.

Title: Optical contactless speed and displacement measurement - using laser beams with polarisation planes at right angles focussed onto same spot on moving object
Inventor: CHRESTIN DIRK DIPL PHYS
IPC: G01P5/26
Filed: 1979-06-06
Abstract: The appts. is used for contactless photoelectric speed measurement in at least one coordinate along the surface of rigid or deformable objects. It uses at least one pair of phase and frequency correlated light beams impinging on the measured object at different angles. The light source is a laser, producing coherent light, and the light beam passes through several lenses and a diffraction grating which acts as a beam splitter. In the simplest application, a pair of light beams is the produced, allowing measurement in one coordinate only. The laser produces linearly polarised light. One of the light beams from the diffraction grating is passed through a lambda/2 plate which rotates the plane of polarisation through 90 deg. Lenses focus the two beams onto the object and reflected light returning along the axis of the system passes through a beam splitting prism to photodetectors.
