Abstract: ABSTRACT OF THE DISCLOSURE           A four-way diverter valve has a cylindrical housing wall and two pair of in-line ports for connection to a heat exchanger condenser or the like.  Disposed within the interior of the valve housing is a longitudinal hollow tubular fluid flow diverter element mounted for rotation on a transverse axis coinciding with the center axis of the cylindrical wall.  The tubular diverter element is provided with an inner generally diametrical baffle which forms separate but parallel fluid flow passages therein.  Diametrically opposed longitudinally extend-ing radial ribs are disposed on the outer wall of the tubular diverter element and directly in line with the edges of the inner baffle.  The end closure plates for the valve are provided with a first stop device for engagement by the diverter element ribs for properly positioning the diverter element in a normal position parallel to the in-line ports.  A second stop means is provided for rib engagement to properly position the diverter element in rotated position when the fluid flow downstream of the valve is to be reversed.  Diagonally opposed ports in the valve housing are surrounded by concave seats which are inclined at an acute angle to the cylindrical housing wall and the axis of rotation of the tubular diverter element.  The end edges of the diverter element wall and baffle ends are slanted trans-versely at substantially the same angle to provide an engageable planular interface, in section, between the parts.  Each seat extends circumferentially toward the other adjacent port and is intersected by a central longitudinal plane containing the baffle of the tubular diverter element when the latter is in its normal position so that the seat terminates on the side of the diverter element baffle remote from the surrounded port when the diverter element is in normal position.  An axle mounts the tubular diverter element for rotation about its axis.  A device is provided to shift the axle axially when desired. Thus, the diverter element and its associated parts can be tightened onto the seats, but also when the diverter element is to be rotated from its normal to its second position, the end edges of the associated parts can be lifted from the circum-ferential tapered seats for free subsequent rotation.  Resi-lient seals are provided in association with the longitudinal ribs and stops.  The seal is maintained during shifting of the diverter element along its axis.

Abstract: Abstract of the Disclosure The present invention relates to a photosensitive transfer material, which comprises a flexible temporary support film which is preferably transparent, a thermo-plastic photosensitive layer, optionally a flexible cover film on the free side of the photosensitive layer and, optionally, an intermediate layer between the support film and the photosensitive layer.  The photosensitive transfer material is suitable for manufacturing photore-sist stencils and solder masks.  The temporary support film has a rough surface which exerts an embossing effect on the surface of the photosensitive layer and the inter-mediate layer, respectively.  The mat-finish of the intermediate layer prevents an irregular deformation of this layer in moist air, while the mat-finish of the photosensitive layer precludes unwanted reflections.

Abstract: ABSTRACT:     A coaxial cable tap connector comprises a cable-engaging member having a channel therealong in which a section of a coaxial cable is to be disposed. Outer conductor contact members are located in the cable-engaging member within the channel on each side of a threaded hole, the contact members including post sections disposed within a printed circuit board guide slot of the cable-engaging member. A clamp-retaining member has a movable clamp member disposed therein and is slidably positioned onto the cable-engaging member, the clamp member having a channel for engaging the cable. A driving member is mounted on the clamp-retaining member and engages the clamp member thereby driving the clamp member into clamping engagement with the cable and clamping the cable between the clamp member and the cable-engaging member within the channels thereof. The clamping operation causes the outer conductor contact members to penetrate an outer jacket of the cable and make electrical connection with an outer conductor of the cable. A signal probe assembly is threadably positioned in the threaded hole causing a spring-biased signal probe member to rotatingly penetrate into the cable so that a contact section of the signal probe member makes electrical connection with the center conductor. A post section of the signal probe member is disposed within the printed circuit board guide slot so that it and the post sections of the outer conductor contact members can be electrically connected with electrical contacts on a printed circuit board of a transceiver member to be mounted onto the tap connector.

Abstract: ABSTRACT OF THE DISCLOSURE:  A process of manufacturing a high-efficiency, stable CdS-Cu2S solar cell using A thick film methodology, which process comprises the steps of:  A - preparing a CdS slurry from a dopped, CdS powder; B - depositing a 10-15 µ thick layer of the CdS slurry onto a substrate plated with thin layers of Zn and Cd; C - drying the CdS layered substrate and subjecting it to heat treatment; D   pressing the heat-treated substrate; E - subjecting the pressed, CdS layered substrate to another heat treatment to cause CdS recristallisation and annealing; F - forming a thin, barriering layer of CuxS onto the surface of the heat-treated, CdS layered substrate under an inert atmosphere to produce a barriered, CdS-CuxS layered assembly G - subjecting the barriered, CdS-CuxS layered assembly to heat treatment under a H2 atmosphere in the presence of CaO; H - providing an upper conductor onto the upper surface of the heat treated assembly to complete the desired, stable CdS-Cu2S solar cell; and I - encapsulating the obtained cell.  This process is advantageous in that it can be carried out with a very simple equipment and sequence of steps, thereby making the overall cost of the resulting solar cells, even when encap-sulated with glass, advantageously comparable with the overall cost involved for the manufacture of the cheapest known silicon-based solar cells.

Abstract: FIBER OPTIC AMPLIFIER Abstract of the Disclosure A pair of small diameter optical fibers are arranged in a side-by-side configuration, the first fiber providing a  pumping  source,  and  the  second  fiber  doped  with  a material which will lase at the signal  frequency.   The signal to be amplified propagates through the second fiber to stimulate emission of coherent light from the lasing material,  resulting in amplification of the signal.  The refractive  index  of  the  first  and  second  fibers  are selected such that the signal in the second fiber is well guided,  while the pumping  light in the first fiber  is unguided, yielding low losses in the second fiber but high transfer of the pumping light from the first fiber to the second fiber.

Abstract: ABSTRACT OF THE DISCLOSURE A method and an apparatus for reducing the risk of ignition and fire in the preparation of hydrogen peroxide according to the anthraquinone method are disclosed. In the anthraquinone method, anthrahydroquinone derivatives are oxidized by means of an oxygen-containing gas. In the described method, the supply of the oxygen-containing gas is automatically interrupted when light and/or heat radiation from the point or points where the oxygen-containing gas is introduced in the working solution impinges on light and/or heat radiation detectors which are so disposed that they can receive such radiation. Preferably, a gas which is inert to the oxygen-containing gas and the working solution is thereafter supplied.  The apparatus for carrying out the method comprises a reaction vessel (1) and one or more gas inlet conduits (3) as well as light and/or heat radiation detectors (6) which are arranged so as to receive light and/or heat radiation from the point or points (7) where the oxygen-containing gas is introduced in the working solution. In addition, to the gas inlet conduit or conduits (3) are connected control means (9, 10) which interrupt the supply of the oxygen-containing gas upon impulses from the light and/or heat radiation detectors and which start the supply of a gas which is inert to the oxygen-containing gas and the working solution.

Abstract: REMAPPING TECHNIQUE FOR HANDLING MEDIA DEFECTS          IN A DISC DRIVE SYSTEM                      ABSTRACT OF THE DISCLOSURE     A remapping technique for handling media defects in a disc drive system is disclosed.  Each surface on each disc is divided into a number of tracks with the corresponding track on each disc defining a cylinder.  Each surface in further divided into a plurality of sectors.  Each sector is each cylinder not having a defect is assigned a logical address in sequential order such that as the discs rotate and as the head address increments within a cylinder, each succeeding defect-free sector within that cylinder has a logical address which is related to the logical address of the preceeding defect-free sector.  Defective sectors are labelled with an appropriate unique pattern in their headers so that they can be identified and distinguished from logical address numbers.         A predetermined number of sectors at the end of each cylinder are allocated as spare, the number of spares being at least as large as the number of potentially defective sectors in a cylinder and the number of spares to which logical addresses are assigned being equal to the number of non-spare sectors which are defective.  In using the technique, each defect-free sector in a cylinder is located and assigned its logical address.  In transferring information, the header address of a sector in a cylinder is compared with the logical address expected at that location.  If the addresses compare, the data at that sector is transferred.  If the addresses do not compare the header address at the next physical sector is compared with the expected address.  The procedure is repeated until the address at a physical sector compares with the logical expected address.  However, if the sequence of mis-compares exceeds a predetermined number, the sequencing operation is terminated and an error signal generated.  The technique eliminates moving the heads radially inward or radially outward to spare tracks allocated for data belonging in defective sectors as in most prior art systems.
