Abstract: G. R. Deacon 1A            SINGLE OPTICAL FIBER CONNECTOR UTILIZING      SPHERICAL ALIGNMENT ELEMENTS     ABSTRACT OF THE DISCLOSURE     A connector for coupling a pair of single optical fibers is disclosed.  Each contact of the connec-tor utilizes three spheres of equal diameter defining a tricuspid interstitial space therebetween into which the end of a fiber is mounted.  The spheres are embraced by a circular race.  In the preferred embodiment, the spheres engage each other and the race.  When a pair of contacts are mated in axial abutting relationship, the spheres in the mating contacts nest with respect to each other, there-by precisely laterally aligning the optical fibers which are mounted in the interstitial spaces of the sets of spheres in the two contacts.  In another embodiment, the spheres are dimensioned so they do not engage each other, but engage the optical fiber at three points.  Also, more than three spheres may be mounted in a contact for positioning a fiber therein.

Abstract: RCA 73,852 Abstract A signal seeking tuning system includes provisions for allowing the direct selection of channels.  It includes a memory for storing lower and upper boundaries of a tuning control voltage range for each channel which may be selected.  When a channel is selected, a microcomputer causes the memory location corresponding to one of the boundaries associated with the selected channel to be addressed and causes a tuning voltage generator to change the magnitude of the tuning control voltage in the direction of the boundary.  A comparator determines when the tuning control voltage reaches the boundary.  Thereafter, the microcomputer controls a signal seeking operation between the boundaries to tune the RF carrier associated with the selected channel.

Title: Process for drying organic solid materials using steam
Inventor: JANUSCH ALOIS
IPC: C10F5/00
Filed: 1980-10-14
Granted: 1983-03-15
Abstract: A b s t r a c t The process for drying as well as for, if desired, modification of the structure of organic solid material, such as for example brown coals, is using steam as the drying agent. The organic solid materials have their upper grain size limited to approximately 50 mm and are suspended in water and heated under a pressure exceeding atmospheric pressure. It is already when preparing this suspension that a first pre-drying is effected. In the following the selected operating pressure exceeding atmospheric pressure is maintained or increased and the suspension is centri-fuged in at least one further drying stage. In all drying stages succeding the stage in which the suspension is pre-pared heating is effected by supplying steam. The suspended solid materials are continuously discharged from the last drying stage maintained under a pressure exceeding atmospheric pressure and pressure-released.

Abstract: PROCESS FOR THE MANUFACTURE OF DESULFURIZING AGENTS          FOR CRUDE IRON OR STEEL MELTS      ABSTRACT OF THE DISCLOSURE:    The present invention relates to a process for the manufacture of desulfurizing agents containing 1 - 6 % by weight of chemically bonded water, based on calcium oxide-containing calcium carbide, for crude iron and steel melts. To this end, a molten mixture of calcium carbide and calcium oxide with a CaO content of 20 to 80 % by weight is produced, which is allowed to solidify into a block. Next, the block which still has an average temperature of more than 400° C, is rough-crushed to particles with a size of less than 150 mm and calcium oxide is added to the comminuted mixture, which still has a temperature of at least 400° C, in accordance with the CaO content desired in the end product. The mixture is finally ground in the presence of air or nitrogen with a moisture content of from 5 to 20 g/m3 (at 1.013 bar and 273.15 K) at temperatures below 100° C to particles with a size of less than 10 mm.

Abstract: PHOTOMETRIC APPARATUS AND METHOD     Arnold C. Bilstad Richard I. Brown Michael Wicnienski ABSTRACT OF THE DISCLOSURE           Photometric apparatus and method for determining the absorbance ratio, in a sample, of two different wave-length lights.  A first light is given a reference inten-sity and is passed through the sample.  A second light is passed through the sample and its intensity is varied so that the intensity of the second light that has passed through the sample is equal to the intensity of the first light that has passed through the sample.  When these intensities are equal, the intensity of the second light is detected in a state wherein it has not passed through the sample, resulting in an equivalent to the ratio of the absorbance in the sample of the second light and the first light.

Title: Mechanism for feeding and transporting printing  plates

Granted: 1984-01-10
Abstract: ABSTRACT OF THE DISCLOSURE     A mechanism for feeding and transporting printing plates to an exposure table with the aid of transport rollers.  The uppermost of the printing plates is stacked in a plate holder.  This plate is gripped by a swiveling lifting cylinder and is, after being swung through a semi-circular arc movement, deposited on a suction plate of the exposure table.  The transport rollers, which are arranged on either side of the suction plate, are driven by a drive roller in each row via drive belts.  Those transport rollers which are the first in each row (from the standpoint of the direction of printing plate travel)  are arranged on swivel blocks which are swiveled outwardly from the rows before the printing plate is put down.  This enables the forward part of the printing plate to be deposited on the suction plate without jamming.  As soon as the printing plate rests on the suction plate, the first transport rollers are swiveled towards the lateral edges of the printing plate which is then transported forward, its lateral edges being guided in grooves provided in the transport rollers.

Abstract: ELECTROMAGNET FOR A MECHANICAL LATCH RELAY   Abstract of the Disclosure A mechanical latch attachment (20) for a control relay (21) includes a mechanical latch movement (77), a solenoid (49), and a pair of contact cartridges (33) that are disposed in a housing (25).  The wear-resistant latch movement (77) has a latch (95) with teeth (103) on one end that are engaged by a pair of pivotable, hooked pawls (105).  The latch (95) is coupled to an operating plunger (79) through a contact actuator (82).  The operating plunger (79) can be coupled to a conven-tional control relay (21), which moves the plunger (79) upon the closing of its relay armature (30) to actuate the contacts (35, 36) in both the relay (21) and the attachment (20) and to move the latch (95) to a position where it is restricted by the pawls (105).  Th restriction of the latch (95) holds the relay armature (30) closed and the contacts (35, 36) actuate even though the relay (21) is deenergized.  The solenoid (49) has an armature (62) that can be moved mechanically or elec-trically to release the latch (95) from the pawls (105).  Re-lays with a mechanical latch attachment provide quiet opera-tion and retain their operated state even in the event of a power failure.

Abstract: Abstract ELECTRICAL CONNECTOR COUPLING RING      HAVING AN INTEGRAL SPRING      The invention is an electrical connector assembly characterized by a plurality of resiliently deflectable fingers (11) which extend between a shoulder (12) in the coupling ring and a shoulder (22) of the housing (20) to provide  a bias  between  the  coupling  ring (10) and  the housing (20) when  the  coupling  ring (10) is  completely threaded onto another connector housing.  The fingers (11) may be integrally molded into either the coupling ring or the housing shoulder eliminating the need for an extra biasing member.  The bias increases the force of friction on the threads in the coupling  ring when it is fully mated to retard unwanted rotation, i.e., uncoupling.     (FIGURE 6)

Abstract: MENISCUS PROSTHESIS                  ABSTRACT      A meniscus prosthetic device for a human knee joint can be inserted into the knee joint so that the articulating cartilage in the knee totally remains intact.  The prosthetic device translates between the articulating cartilage during normal knee movement.  Insertion of the prosthetic device is accomplished by applying force on the ends of the device, thereby elastically spreading them, and placing the device between the tibial articulating cartilage and one of the femoral condyles.  The forces thus applied can then be released causing the device to conform to its original C-shape.  Prominences on the ends of the device may superiorly extend into the space defined by the femoral condyles, thereby securing the device in place.
