Abstract: ABSTRACT OF THE DISCLOSURE A beam projector which is controlled to alternately transmit rectangular cross-sectional beams substantially parallel to a projection axis, wherein the beams are respec-tively pulse modulated over a correspondingly distinct pulse rate frequency range to supply yaw and pitch information and are respectively scanned in a direction correspondingly or-thogonal to the cross-sectional length of each beam.  The size format of the beam cross-sections and the angles of scan are controlled according to a predetermined time variable function.  In a first time period, the largest cross-sectional beams are alternately transmitted and the scan angle is de-creased as a function of time, so that a fixed area of detect-able information is available for detection with respect to an imaginary orthogonal reference plane moving along the projection axis at a rate corresponding to the predetermined time variable function.  In subsequent time periods propor-tionately smaller cross-sectional beams are transmitted and the scan angle is continually controlled.  The disclosed embodiment employs the use of a single set of proportionately different size formatted cross-sectional laser sources as a radiation generator, a scanning mechanism, a vibrationally modulated Pechan type prism and a fixed focus optical system to effect alternately transmitted beams, of selectable cross-section, orthogonally oriented and scanned with respect to each other.

Abstract: ABSTRACT No Bake foundry cores and molds for casting metals are prepared by using a binder comprising a polyol generally derived from alkoxylating an amine compound and a polyisocyanate.  The binder is especially useful for casting non-ferrous metals, for example, the casting of aluminum, magnesium and other light weight metals.  The cores and molds produced for casting aluminum and other light weight metals exhibit excellent shakeout while retain-ing other desirable core and mold properties.  In addition the binders of this invention would have been observed to have an autocatalytic nature.

Abstract: CONTAINERS AND CLOSURES THEREFOR    Abstract of the Disclosure In a container and closure assembly, there is a resilient seal between the two components and the resiliency of the seal determines the normal relative closed positions of the closure and container.  When the assembly is included within a stack, there is movement of the closure in the closing direction further to compress the seal.  To prevent over-compression of the seal, opposed movement limiting surfaces are provided upon the closure and container, these surfaces being slightly spaced normally, but closing together to take loads directly from closure to container and thus avoid overloading the seal, when the assembly is located in a stack.

Abstract: Disclosure Number                             Docket Number ABSTRACT     Method of doping silicon with boron by means of diffusion, where in a first heating process the silicon is exposed to a gas stream con-taining boron and oxygen in a predetermined quantitative ratio, with a boron glass layer forming on the silicon, and beneath said boron glass layer, in the unmasked areas, an SiB6 layer, where the boron glass, without the silicon being substantially affected, is subsequently removed, and where finally in a second heating process boron is driven into the silicon.            The method is suitable for producing silicon areas of low as well as of high boron doping. For making the former, the gas stream contains oxygen during the entire first heating process, and the drive-in is performed in an oxi-dizing atmosphere. For the entire silicon bodies and batches highly homogeneous Rs and xj values are reproducibly obtained. When making the highly doped areas the phase during the first heat-ing process when the boron coating is taking place is very short, and it is only during that phase that the gas stream also contains oxygen. Driving-in takes place in an inert atmosphere, It is important to note that the thus produced boron-doped areas can overlap with highly ar-senic-doped areas without any dislocations being produced in the over-lapping areas.

Abstract: ABSTRACT A novel joint prosthesis, particularly suitable as a metacarpophalan-geal joint prosthesis, is disclosed comprising first and second intramedullary plugs adapted to be secured to the walls of the intramedullary canals of the two bones forming the joint, and first and second components each comprising a bear-ing portion and a stem slidably received in a longitudinal bore provided in each of said intramedullary plugs.  Transmission of stresses to the bone-prosthesis fixation interfaces is substantially reduced as a result of the freedom of motion of the stems within these longitudinal bores.  In a preferred embodiment, axial rotation of one, but only one, of said stems with respect to the intramedullary plug receiving it is prevented.  Use of preferred configurations for the bearing portions of the two components provides an accurate reproduction of the movement and degrees of freedom of the natural metacarpophalangeal joint.

Abstract: ABSTRACT OF THE DISCLOSURE A high bit density is provided for static memory cells in which a semiconductor layer carried on a semiconductor body has strip-shaped insulation zones extending to the semiconductor body and limiting a memory cell. A gate oxide layer is applied to the boundary surface of the semiconductor layer and has a polysilicon layer which is highly doped and covered with a first inter-mediate oxide layer. A drive line and the gate are structured by a first, selective, vertically aligned, reactive plasma etching process. Sections of the drive line at the ends thereof are removed by isotropic etching and the resulting recesses are filled in a thermal oxidation step. The portion of the gate oxide layer adjacent the structured parts is removed by a second, select-ive, vertically aligned, reactive plasma etching process. A second poly-silicon layer is deposited, highly doped and covered with a second intermediate oxide layer. Another drive line having a part contacting a doped region in the semiconductor layer, the region being formed by ion implantation, is structured by a third, selective, vertically aligned, reactive plasma etching process. A recess is then formed by a fourth, selective, vertically aligned, reactive plasma etching process and an isotropic etching step is performed to remove those parts of the drive line which extend to the last-mentioned recess. A fifth, selective, vertically aligned, reactive plasma etching process is per-formed for removing the oxide layer covering the boundary surface of the semi-conductor layer within the recess. A third, silicon layer is deposited and covered with a third intermediate oxide layer. Another recess is formed in the third intermediate oxide layer above the recess provided by the fourth reactive plasma etching process in a sixth, selective, reactive plasma etching process. A conductive coating is then applied to the third polysilicon layer and is provided with an electrical terminal.

Abstract: Abstract SHOE LASTING MACHINE      Provision is made for enabling the adhesive applying nozzles on a shoe lasting machine to be initially positioned offset from the longitudinal center line of the machine, selectively at one side or the other according to whether the shoe to be lasted is a left or a right. To this end each nozzle is movable, independently of the other, widthwise of the shoe bottom and has stop means associated therewith. At the start of a machine cycle, one stop means is in an operative position, in which its associated nozzle is in a desired offset position, while the other stop means is in a retracted position, allowing its associated nozzle to move to a position adjacent the first-mentioned nozzle. After engagement with the shoe bottom said one stop means is also retracted, so that both nozzles are then free to follow the edge contour of the shoe bottom without constraint.
