Title: Light-conducting element, in particular for laser transmitters of modular construction
Inventor: ALTHAUS HANS-LUDWIG DIPL PHYS
IPC: G02B6/42
Filed: 1987-08-31
Abstract: The invention relates to a light-conducting element (1) in the form of an elongate fibre or substrate track which is applied to a backing platelet (6), has a light input and a light output and is produced from a medium which routes the light rays in the interior with low losses by means of reflection, the medium having a correspondingly higher refractive index than that of the adjacent medium, for the purpose of optically interfacing (coupling) a laser diode (4) to an optical waveguide (9). With this light-conducting element (1), an optimum interfacing of the light of a laser diode into an optical waveguide is to be achieved, in particular without additional means. The invention makes provision to this end for the light-conducting element (1) to be split on the light input side into two symmetrical parts and to be bent or angled in such a manner that two mutually facing light input surfaces (2) are formed which are opposite the two plane-parallel light output surfaces, acting as optical resonator (cavity), of the laser diode (4), and for the light-conducting element (1) at the light output (5) to be optically matched to the optical waveguide (9) to be interfaced. The light-conducting element according to the invention is used in particular in laser transmitters of modular construction. <IMAGE>
Patent DE-3734956-A1 (DE)
Inventor: SMITH MICHAEL NORMAN
IPC: B26D7/20
Filed: 1987-10-15
Abstract: A ledger assembly for a continuous rod cut-off includes a rigid beam (12) carrying ledger tubes (10) and pivotally supported by fibreglass springs (16, 22). Vertical springs (22) resist the cutting force of the cut-off knife (30, Fig. 2) and allow reciprocal movement of the tubes (10) while imparting a vertical displacement to the beam (12) so that the tubes follow a straight path along the rod line (28). A horizontal spring (16) allows this vertical displacement while providing lateral stiffness for the base of the beam (12). A drive arrangement for the beam (12) includes a lubricating system for a bearing (42) of a connecting rod (36) in which lubricant is collected for return by action of centrifugal force in a housing (72, Figs. 5 and 7) located on the side of the bearing opposite a lubricant supply path (86, 88, Figs. 5 and 7) through a crankshaft (40). <IMAGE>

Patent DE-3804365-A1 (DE)
Title: Motor vehicle with main and secondary radiator
Inventor: PRANTL JOSEF
IPC: B60H1/32
Filed: 1988-02-12
Abstract: A motor vehicle contains a main and at least one secondary radiator. The air supply to the secondary radiator through a pressure fan in a separate air feed duct is completely separate from that of the main radiator. In order to obtain the largest possible cooling surface in the given cross-section of the air feed duct, the secondary radiator is designed curved or angled towards the outlet side. The large surface on the outlet side reduces pressure losses and the distance of the fan from the secondary radiator necessitated by the said arrangement improves the flow conditions.

Title: Flapping wing inertia control
Inventor: RINNAU HANS-JOACHIM
IPC: B64C33/02
Filed: 1988-05-05
Abstract: A flapping wing propulsion system having a flapping wing inertia control for producing an effective "coupled parallel/rotating flapping movement", the lift force P acting virtually on the leading edge of the wing on the flapping surfaces which are mounted at the cross-sectional centre of gravity such that they can rotate to a limited extent and are held in an unstable manner in the basic position by springs, and the wing thus rotates into the respective flapping direction, which is carried out by inertia forces, remaining in this state during the parallel flapping movement. In addition, at the end of each upward stroke and downward stroke, the mass of the wing arrangement is absorbed by low-damping springs which store the excess flapping energy and feed it back into the drive process. <IMAGE>

Title: Arrangement for measuring polarisation-optical path differences
Inventor: DANZ RAINER DIPL PHYS
IPC: G01N21/21
Filed: 1989-02-28
Abstract: The arrangement for measuring polarisation-optical path differences is applied in optical devices with which, for the analysis of the phase content or of the structures of the images or substances to be examined, circularly polarised light is used for the azimuth-independent representation of the path difference caused by the sample. A prominent field of application of the invention is polarisation microscopy, for example in the static or location-dependent examination of anisotropic solids or directed biological substances. The object of azimuth-independent path difference measurement is achieved according to the invention by arranging, between an object and a second quarter-wave retarder of a circular polarisation device, an optically active component, and by providing mechanical, electrical or magnetic means known per se, with which the azimuth of the oscillation direction of the bundle of light leaving this component is continuously varied. <IMAGE>

Title: Gas nozzle
Inventor: RUNKEL WALTER DR ING
IPC: D02G1/04
Filed: 1989-05-13
Abstract: Gas nozzle, by means of which a false twist is imparted to a running thread. The abovementioned gas nozzle exhibits a thread duct (12). A gas stream is blown into the thread duct transversely to the thread direction. Swirling is produced in that the gas ducts open tangentially into the thread duct. Consequently, the intensity of the swirling is rigidly predetermined. Instead of this, there is introduced, into the gas duct, a helical duct guide, by way of which a swirling flow is impressed on the gas. The helical duct guide can be produced by exchangeable inserts (30). <IMAGE>

Title: FM HF signal changeover switching - uses diversity functioning only when preset min.. signal level is present and specifically defined
Inventor: VOLKE PETER
IPC: H04B7/08
Filed: 1989-11-23
Abstract: The switching is carried out in dependence on aerial diversity for the car radios. The aerial system has pref. an aerial of high reception power for FM and AM, i.e. the main aerial, and at least another aerial for FM reception only. The diversity is functioning only when a preset min. signal level is available defined by a top ON switching value and a lower OFF switching value, forming thresholds. On not reaching the OFF value the main aerial is switched-on. The same mechanism is used for FM diversity function switching-of, and for change-over for reception via the main aerial, when the receiver is tuned to AM. The diversity circuit contains a demodulator for the IF signal processed by the FM tuner and IF amplifier. ADVANTAGE - Simple reduction of unfavourable reception conditions.
