Abstract: ABSTRACT OF THE DISCLOSURE           A panel for elevated access floors is disclosed in which the panel is formed of reinforced expanded lightweight concrete.  The reinforcing is provided by a grid including two arrays of parallel reinforcing rods which extend parallel to the associated panel edges and perpendicular to the rods of the other grid.  A frame is provided by the grid around the two arrays.  The grid is located adjacent to the lower surface of the body and divides the body into a plurality of square zones.  Located in each zone, excepting the zones at the corners, is a pyramid-shaped cavity which extends from a base at the lower surface of the panel upwardly at about 45° to an apex spaced from the upper surface of the panel.  The presence of the pyramid-shaped cavities does not materially reduce the strength of the panel when compared to a similar panel without such  cavities, but reduces the weight of the panel and the material required to manufacture the panel.

Abstract: Dispositif automatique de réglage optimal de l'avance à l'allumage d'un moteur à allumage commandé.  Le dispositif comporte un ensemble de détection de la présence éventuelle du cliquetis pendant la combustion, cet ensemble étant sensibles aux vibrations du moteur, exclusivement pendant une fraction de la phase de combustion correspondant à un  intervalle angulaire sélectionné de la rotation de l'arbre moteur.  Des moyens réversibles sont actionnés par l'ensemble de détection et connectés au circuit d'allumage pour provoquer un retard à l'allumage lors de la détection d'un certain nombre de cliquetis consécutifs.  Un organe de repérage de la rotation de l'arbre moteur produit des impulsions électriques correspondant à des positions angulaires successives régulièrement espacées de l'arbre moteur.  Les moyens réversibles comportent un premier organe totalisateur produisant un signal après totalisation d'un nombre fixé de cycles-moteurs, un second organe totalisateur produisant un signal après totalisation d'un nombre fixé de cliquetis du moteur, chacun de ces organes ayant une borne de sortie reliée à des bornes de remise à zéro des deux organes totalisateurs, des compteurs-décompteurs électriques reliés  à  ces deux derniers organes et fournissant un signal de réglage d'avance, fonction de la différence entre les nombres respectifs de signaux produits par les organes et une commande du circuit d'allumage connectée aux organes de comptage-décomptage et de repérage de la rotation de l'arbre moteur.

Abstract: A B S T R A C T   A method of joining pipes in which a sleeve is placed over the adjacent ends of the pipes so as to overlap each pipe.   The sleeve fits with clearance around the pipe ends.    The ends of the clearance space are closed by inflating hollow sealing rings and then epoxy resin is injected into the clearance space to fill the space.    The pressure of the epoxy resin composition is then raised to a pressure substantially greater than atmospheric and the pressure is maintained until the resin composition is set.

Abstract: VERSATILE CUTTING TOOL FOR GEAR MANUFACTURE     Abstract of the Disclosure Versatile face-mill cutting tool apparatus particularly useful in the manufacture of relatively large gears having diameters of two to six feet (0.6 to 2 meters).  A single cutter body can be used in combination with one set of cutter blades to satisfy a wide variety of tool parameters:   Blades and blade holders can be readily reversed as required for clockwise or counter-clockwise tool rotation.  The angle of the cutting edge of each blade can be adjusted through a fairly wide range of settings as required by the design of the tooth slot being cut.  Fine radial adjustments of cutting blades can be made for cutter truing and gear tooth development without shims.  This latter feature is accomplished by moving the blade holders along respective straight line paths which, when extended, form an equilateral convex polygon about the center of rotation of the cutter body.

Abstract: ABSTRACT OF THE DISCLOSURE A hydraulic turbo-machine such as a Francis turbine is provided with a highly effective peripheral seal to greatly limit the quantity of water or other working liquid flowing past the outside of the runner, into the shroud space formed between the runner shroud and the runner housing. The seal comprises a double screw arrangement having a coarse thread, generally of rectangular section, projecting from an annular band of the runner shroud and a like thread, but of opposite hand, in projecting close facing relation therewith on the runner housing, the handing of the respective threads being related to the direction of rotation of the runner, to provide a seal possessing markedly low leakage flow charac-teristics. The arrangement is of particular value for use with machines having a low drag liquid contained within the shroud space. The effectiveness of the seal greatly reduces the rate of degradation of the low drag liquid by limiting the admission, as leakage, of working liquid to the shroud space.

Abstract: Abstract of the Disclosure A bicycle frame comprised tubes closed at their ends and lugs for connecting the tubes to form the frame, which lugs are formed by die casting in dies in which the tubes are arranged so as to integrally surround the closed ends of the tubes by the die-cast lugs.  The tubes are previously formed at their ends with tapered portions each extending from that corresponding to an extreme end of a boss of the lug surrounding the end of the tube toward an extreme end of the tube.  The outer surfaces of the bosses of the die-cast lugs are in substantially constant outer diameter or slightly tapered, thereby, in conjuction with the tapered portions of the tube, eliminating stress concen-trations at the extreme ends of the bosses of the lugs, and saving the amount of the die-cast metal resulting into light weight bicycles which can save the driving power and cost of manufacture.

Abstract: ABSTRACT      An improved spring shackle assembly is utilized in an im-proved vehicle suspension system and includes a pair of socket assemblies which connect an end portion of a leaf spring with a mounting bracket.   Each of the socket assemblies includes a rigid metal housing having an inner surface which defines a socket chamber in which a bearing liner is disposed.  Each of the bearing liners encloses a spherical end portion of a ball stud.  Each ball stud has a generally cylindrical shank which extends into an open-ing formed in an end portion of the spring.  In order to tend to minimize the sideward load applied to the mounting bracket, the bearing liners have spherical surfaces which cooperate with the spherical head ends of the ball studs so that offsetting axial or sidewise forces are applied to the bearing liners by the ball studs.  The socket assembly has a unitary construction to facili-tate assembly and to minimize the chance for dirt and other foreign materials to enter the socket chamber.  In one embodiment of the invention, the bearing liners are integrally formed of a suitable polymeric material.  In another embodiment of the inven-tion, the bearing liners are formed in two sections.  One of the two bearing sections carries a larger bearing load and is formed of a meterial having a higher modulus of elasticity than the other bearing section.

Abstract: A METHOD AND APPARATUS FOR REMOVING                     ROOM REVERBERATION            Abstract of the Disclosure Room reverberation and other uncorrelated signal sources characteristic of monaural systems are removed, in accordance with the principles of this invention, by employing two microphones at the sound source and by manipulating the signals of the two microphones to develop a single nonreverberant signal.  Both early echoes and late echoes in the signal received by each microphone are removed by manipulating the signals of the two microphones in the frequency domain.  Corresponding frequency samples of the two signals are co-phased and added and the magnitude of each resulting frequency sample is modified in accordance with the computed cross-correlation between the corresponding frequency samples.  The modified frequency samples are combined and transformed to form the nonreverberant or correlated signal portion.
