IPC: F21S8/00
Filed: 1986-12-31
Abstract: The light-emitting part of the sign consists of a light source between a rear reflector and a front plate. The reflector is usually parabolic, and the front plate carries a colour filter, e.g. if the installation is a traffic light, and/or a warning symbol, e.g. a pedestrian walking or a train. The front plate (9) of the beam unit may be convex, concave or flat. - In front of the plate is a mask or lens (6), which consists of a framework of plates with horizontal surfaces (7), which carry an opaque and non-reflective coating (7'), and angled surfaces (8), which join the rear edges of one horizontal plate to the front edge of the one above. The light beam can pass easily through the transparent angled surfaces, while sunlight is prevented from reaching the angled plates by the horizontal plates.(3/4)

Abstract: ABSTRACT OF THE DISCLOSURE         A DC measuring circuit for power rectifiers is described wherein primary line  current is utilized to measure direct current output.  In the measuring circuit line  current transformers are connected to a multiphase instrument rectifier through a phase shifting current transformer which is adjustable to compensate for difference between the primary to secondary line current phase shift characteristic of the power transformer and any phase shift in the  line current transformers. By such compensation the average value of rectified primary line current in the  measuring circuit is maintained  independent of the commutating angle of the rectified power current.

Abstract: ABSTRACT     A high temperature chemical reaction process is disclosed which is characterized by steps wherein an annular envelope of an inert fluid which is substantially transparent to radiation is generated within a shell of a refractory material which re-flects radiation, the volume enclosed by the shell constituting a black body cavity, the envelope having substantial axial length and the interior of the envelope defining a reaction chamber.          At least one reactant is passed into the black body cavity and through the reaction chamber along a predetermined path substan-tially coincident with the longitudinal axis of the envelope.          High intensity radiant energy is directed into the reaction chamber to coincide with at least a portion of the predeter-mined path of the reactants, sufficient radiant energy being absorbed within the reaction chamber to raise the temperature of the reactants to a level required to initiate and sustain the desired chemical reaction.  This process can be utilized to car-ry out high temperature chemical reactions such as the dissocia-tion of methane to obtain carbon black and hydrogen.  Also dis-closed is a reactor for carrying out said process.

Abstract: ABSTRACT           An improved fastener assembly includes helical in-ternal and external thread convolutions.  A generally helical insert having a plurality of turns is disposed between the in-ternal and external thread convolutions.  This insert is resil-iently twisted or flexed from a first condition to a fully deflected condition under the influence of torsion forces appl-ied to the insert by the internal and external thread convolut-ions.  In one embodiment of the invention, the insert has four side surfaces.  When this insert is in the first condition, one pair of side surfaces is disposed in abutting engagement with the leading flanks of the internal and external thread convolut-ions.  At this time the other side surfaces of the insert are spaced apart from the trailing flank surfaces of the thread convolutions.  As used herein, the leading flank surfaces of the thread convolutions are the flank surfaces which, when the thread is about to be assembled with a mating thread, face the mating thread.  Upon twisting of the insert to a deflected con-dition, the side surfaces of the insert move away from the lead-ing flanks of the thread convolutions and move into abutting engagement with the trailing flanks of the thread convolutions.          Under conditions in which it is desired to pretension the inter-nal thread convolution, the internal thread convolution is form-ed with a smaller pitch than the external thread convolution.          In another embodiment of the invention, the insert is provided with an arcuate surface which engages one of the thread convolu-tions and a pair of side surfaces to engage the flanks of the other thread convolution.  The internal and external thread con-volutions may have different pitches to provide a locking action between the insert and the thread convolutions.
