Abstract: Abstract In the prior art, blueprints or other documents that are out of a central storage area, and in the area of the personnel working therewith, have been typically positioned loosely on a desk or working table in a manner so that they get in the way when not being used and/or roll off the desk.  In general when not in use and stored on a desk, such documents are difficult to position conveniently.          The invention is a working table or desk having a grating for vertical storage of material in elongated form, such as rolled blueprints.  The table has a vertically directed opening with grating forming rods extending thereacross to form spaces for inserting rolled documents for storage.  A container is positioned below the opening on the floor to receive the lower ends of the material.  The opening has vertical surfaces having spaced horizontally directed holes therein.  Each hole on each surface is in alignment with an opposite hole in an opposite surface to receive the rods forming the grating.  One of each pair of oppositely aligned holes is deeper than the other to receive a coil spring.  Each rod is inserted into a deeper hole to be in abutment with the spring, the spring being compressed to permit the entry of the rod across the opening and when so compressed the other end of the rod is within the opening and in position to be forced into the opposite hole by the bias of the spring.  The spring thus holds each rod in place.  In order to provide an arrangement of crossing rods to form the grating, holes in faces adjacent to faces having a first group of holes are bored at a higher level so that the rods may fit above the first rods and cross the latter.  Also included is a cover to rest on the upper rods provided to close the opening when it is not being used for storage.  The cover matches the top of the working table.

Abstract: PAPER FEEDING CONTROL APPARATUS     Abstract of the Disclosure Apparatus for controlling the feeding of paper about a printer platen.  Controlled are paper aligning, rear roller feeding, front roller feeding and paper bail operation.  The apparatus is primarily made up of a rocker button, reed switches, a drive motor, a cam gear, a comb, and a paper bail.  Upon operator manipulation of the rocker button, the drive motor is turned on for rotating the cam gear.  Rotation of the cam gear effects bi-directional rotation of the comb and a paper bail arm carrying the paper bail.  Rotation of the comb in a first direction results in 1) a rear feed roller being dis-placed from the platen to provide a feeding path for paper when inserted into the printer, and 2) a paper aligner being positoned for aligning the paper.  Rotation of the comb in a second direction results in the rear feed roller causing engagement of the paper and platen and the paper aligner being brought out of the feeding path of the paper.  Rotation of the paper bail arm in a first direction causes the paper bail to be displaced from the platen.  Rotation in a second direction results in the paper bail causing engagement of the paper and platen.

Abstract: METHOD OF PRODUCING A HIGH DENSITY SILICON CARBIDE PRODUCT                 ABSTRACT         A method of pressureless sintering silicon carbide mixtures to obtain a sintered, dense product when the silicon carbide starting materials do not include a densification aid, such as boron, beryllium or aluminum, is described.  The starting materials are mixtures containing predominantly particulate silicon carbide and include usually less than about 10 and, preferably, less than about 6 percent by weight of carbon in the form of elemental carbon or in the form of a carbon source material.  The mixtures may also contain minor amounts of other additives, such as lubricants, surfactants or agglutinants, to aid in forming a compact, or green body, from the mixtures, or minor amounts of other ceramic materials de-pending upon the nature of the desired final product.  The mixtures are formed into compacts, or green bodies, by known techniques.  The powder compact is sintered under substantially pressureless conditions in a sintering atmosphere containing boron to product a sintered product having a density of at least 85 percent and, preferably, greater than about 90 percent of the theoretical density of silicon carbide.

Abstract: ABSTRACT:           A transmission system for the transmission of binary data symbols.  It is known to use bi-phase modu-lations for the transmission by way of cables in a fre-quency band from 0 Hz to twice the bit rate.  This method is not optimum as regards the intersymbol interference and the signal-to-noise ratio.  Described is a so-called "crankshaft code" which, in combination with a receiver having a special filter characteristic enables a more optimum signal detection, independent of the cable char-acteristic.  The system is used for digital transmission over cables in the local telephone network.

For optical communications systems as well as for video or audio longplay apparatus (VLP/ALP), it is necessary that a semiconductor laser to be used therein is situated in an exact position (x, y) and at an exact distance (z) from a first optical element (for example, a lens) of the optical system coupled to the laser. This is achieved in accordance with the invention by arranging the laser in a bush-shaped cover on which a flange is form-ed. On this flange a holder with a lens is secured by way of a plastic metal solder layer. The lens can be placed in the correct position and at a correct distance from the laser by sliding the holder and by pressing on the holder, the solder layer then being plastically deformed whilst the space in which the laser is accommodated still remains hermetically sealed.
