Title: Internal sealant for concrete
Inventor: BOEHME W
IPC: C04B40/04
Filed: 1980-01-18
Abstract: A method and composition are provided for making a finished concrete structure having a water-impervious surface. A particulate composition of a paraffin wax material, glyceryl fatty-acid esters, and stearic or palmitic acid is added to the aggregate phase and mixed in a wet hydraulic Portland cement mixture. The resultant slurry is then poured and cured. The surface of the cured structure is thereafter heated as by solarization under black pigmented polyethylene sheets to cause the wax particles to melt and invade capillary and other interstices in the surface region of the concrete structure, thereby rendering said structure impervious to the infusion of water and water solubles.

Abstract: Une chaussure (24) concue biomecaniquement possede une construction formant talon (26) ayant une reaction de deflection de force optimale pour une personne particuliere et un emploi particulier. La construction formant talon (26) presente un ressort principal (32) caracterise par un coefficient d'elasticite verticale eleve tout en presentant en meme temps une resistance extremement elevee au cisaillement lateral (coefficient d'elasticite horizontal). Le ressort principal (32) est constitue de preference par un ressorts a disque conique (32', 32'') forme d'un materiau plastique ou d'une pile verticale de ressorts a disques coniques couples de maniere operationnelle. Le ressort principal (32) peut etre noye dans un talon faconne de maniere conventionnelle forme d'un materiau elastique (34) tel que du caoutchouc ou du plastique moule a cellules ouvertes ou fermees fixe a la semelle (30) de la chaussure (24). Dans d'autres modes de realisation, la construction formant talon (26) est fixee de maniere remplacable a la semelle (30) au moyen d'un goujon filete (72) avec ou sans un assemblage intermediaire. Dans un mode preferentiel de realisation, le ressort principal (32) agit de concert avec un organe elastique (34) pour etendre la courbe caracteristique de deflexion de charge du ressort principal. L'organe elastique (34) peut etre le materiau de talon en caoutchouc ou en mousse plastique dans lequel est noye le ressort principal ou bien une colonne (50) d'un materiau hautement elastique tel que du caoutchouc mou situe au centre du ressort principal (32) a disque conique.

Title: Methods and apparatus for x-ray analysis of rapidly moving multicomponent materials
Inventor: CHO BOONG YOUN
IPC: G01N23/08
Filed: 1982-08-09
Abstract: A beam of X-rays is directed into a traveling product (10, 132, 172) such as paper having a constituent such as ash made up of components such as clay, chalk and titanium dioxide. X-rays from the product may produce signal channel responses that are the same to one component but different to another component, and a resultant response indicative of the content of the constituent or component. The X-rays from the product may produce a response to a detected spectrum wherein the intensities of the rays are so distributed as a function of energy that the average effective absorption coefficients for the components are substantially equalized, so that the response will be indicative of the constituent and comparatively unaffected by the relative amounts of the components.

Title: Compatible descrambler for television synchronization
Inventor: DERIDDER DENNIS W
IPC: H04N7/171
Filed: 1984-03-16
Abstract: A descrambling circuit for video signals which have been rendered secure against unauthorized use by suppression or elimination of the horizontal sync signals generates (29) a decoding signal at the receiving end by detection (18, 20) of an unmodified portion of the video signal occurring during the vertical blanking interval or by detection (40) of the 3.58 MHz color burst signal. In this way, descrambling can be accomplished without need for reference to a decoding signal with the scrambled video or a key inserted in the video signal at the transmission end. This also permits a single descrambling circuit to decode video signals which have been scrambled by different techniques.

Patent WO-8901655-A1 (WO)
Inventor: HULSING RAND H
IPC: G01C19/5776
Filed: 1988-08-04
Abstract: A servo loop control for the dither drive of a Coriolis rate sensor is provided. The dither drive includes a pair of electromagnetic coils (70), which are alternately energized to dither a parallelogram frame (50), on which first and second accelerometers (20 and 22) are mounted with their sensitive axes antiparallel to each other. An LVDT position sensor (106) provides a feedback signal indicating the relative position of the two accelerometers or displacement of the parallelogram frame as it is dithered back and forth. The position signal is summed with a driving signal, amplified and summed with a velocity aiding signal and a velocity signal derived by differentiating the position signal. The resulting sum is amplified and again summed with an acceleration aiding input that includes compensation for a phase shift in the motion of the parallelogram frame relative to the driving force applied by the electromagnet coils, and for (I?2 and 1/D?2) nonlinearities where I is the current and D is the pole gap dimension (114). The sum of these signals is used to energize the electromagnetic coils, driving the parellelogram frame with a signal that causes it to dither in a pure sinusoidal fashion. Each of the critical frequencies used in the servo loop is phase locked to a common stable crystal reference frequency, and all components of the servo loop are powered by a common power supply. The servo loop provides improved frequency and phase stability and insensitivity to voltage fluctuations.

Title: Computer disk adjustable write-protect device
Inventor: DI GIESI ANTHONY L
IPC: G11B23/28
Filed: 1989-01-23
Abstract: A flexible magnetic recording medium contained in a protective jacket (10) for storing digital computer information requires a write/erase inhibit function to preserve previously stored information. This function is provided by a continuously lockable shutter (60) inserted into the containment jacket (10). The jacket structure provides shutter-locking means using an outside jacket edge (50) and sealed side flap (49) to apply lateral pressure, confining the enclosed shutter (60) to slide along the jacket margin. Once installed into the containment jacket (10), shutter (60) movement is controlled through an access slot (58) remote from the normal notch (53) provided, and is unemcumbered by any physical projection in the notch (53) or jacket (10). An exernal device facilitates shutter movement through dimple (51) in one direction to block, and in the opposite direction to unblock the write-protect notch (53).
