Abstract: The invention relates to a scraper-chain assembly for scraper-chain conveyors, in particular central or double central scraper-chain conveyors, having a scraper connection to horizontal chain links of the single-strand or two-strand chain assembly. Vertical chain links hooked into the horizontal chain links are provided with longitudinal limbs which have a non-round cross-section, and whose thickness dimension is smaller than that of nose parts of these chain links that connect the longitudinal limbs. For the scraper connection, the scrapers have coupling and locking pins, which extend through internal openings of the horizontal chain links, between the hooked-in vertical chain links and which protrude from the internal openings to form locking pieces which serve to secure the scrapers.
Abstract: The invention relates to a hopper discharging and charging plate conveyor with automatic weighing and apportioning device for bulk materials of all types, there being arranged in the conveying path of the plate conveyor (1) a weighing station (15) which is formed by a weighing bridge which is displaced on load cells (16) or the like and, during conveying operation, determines the bearing weight of the loaded conveying belt by way of repeated measurements. In order to achieve precise weighing results, the horizontal tensile forces of the drawing elements (6), which comprise flat-link chains for example, are isolated from the vertical bearing forces measured at the weighing bridge, this resulting from the fact that the drawing elements (6) are connected to the plate elements (7) of the plate conveyor so as to be freely movable to a limited extent in the vertical direction, and this connection preferably being made via transverse bolts with vertical play in the bolt holes.

Abstract: A landing control system comprising an elongated nonmagnetic strip extending vertically along the length of the shaft, having along its length, at predetermined sites, magnetic adhesive tape containing coded information. A sensor for reading the coded information is mounted on the exterior of the elevator car grasping the nonmagnetic strip by a pair of tape guides, the guides being spaced as to permit the centrally located magnetic adhesive tape to pass freely into the sensing area without, while avoiding contact with the tape.
Abstract: An electrostatic supporting type acceleration detecting gyro apparatus is formed as an active type so as to be able to positively cancel a displacement of a gyro rotor. Control DC voltages for generating electrostatic supporting forces and displacement detection AC voltages for detecting a displacement of gyro rotor are applied to electrostatic supporting electrodes, and mechanism control circuits detect displacement indicating voltage signals (P.sub.1A) through (P.sub.4B). A displacement of the gyro rotor and the control DC voltages applied to the electrostatic supporting electrodes are computed based on the displacement detection voltages (P.sub.1A) through (P.sub.4B) outputted from the mechanism control circuits.
Abstract: Flow agent particles, Aluminum Oxide C, are blended with metal oxide phosphor particles in an amount less than or equal to 2% by weight of the phosphor particles. The blended particles are finely sifted, through a 10 micron screen, in a sonic-sifting apparatus. The sifted particles are introduced into a carrier resin, thermoplastic polymers such as polyamide, polyester, and polypropylene, during the melt-stage of an extrusion and pelletizing process, to form pellets in an amount of less than or equal to 30% by weight of the polymer. The pellets are fed, via a volumetric color chip feeder, into a melt extrusion unit to form multi-filament phosphorescent textile yarn in an amount of less than or equal to 10% by volume of the polymer.
Abstract: An aerating device adapted to be retrofit to existing household lawn mowers comprising a pair of wheels each having a plurality of tines extending therefrom for penetrating a lawn and removing therefrom a section of soil, thereby aerating the lawn. The tines are offset from the center of the wheel to utilize the rotational energy of the wheel and the weight of the lawn mower to penetrate the lawn without the application of additional force by the user. In this manner, a user can simultaneously cut his/her lawn and aerate the same.
Abstract: A method for making polyesterimide varnishes by polycondensing and imidat a mixture of trimellitic anhydride, 4,4'-diamino-diphenyl methane, glycol, dimethyl terephthalate and glycerol or tris(hydroxyethyl) isocyanurate or optionally p,p'-dihydroxy-diphenyl-dimethyl methane, with a transesterification catalyst added, and subsequently dissolving the resulting polyesterimide resin in an organic solvent with a crosslinking catalyst added, characterized by the feature that 2-methyl-1,3-propanediol and/or 2-butyl-2-ethyl-1,3-propanediol is used as the glycol or as one of the glycols.

Abstract: A body furniture is provided having one or more air exhaust ports and a built-in air fan. A top plate having one or more air suction port is positioned on the furniture body, and a tornado-based suction unit is removably placed on the one or more of the air suction ports. The tornado-based suction unit includes a cylinder having a window formed through a peripheral wall thereof, and a suction hole formed through at least one of end surfaces of the cylinder connected to a suction side of the air fan. An artificial tornado is generated within the cylinder and collects contaminated air such as the smoke of cigarettes. The collected contaminated air is cleaned. Minus ions or fragrance may be supplied to air sucked from the suction hole to fill a space around the body.
Abstract: A skill based game presented in a bingo format in which a bowler, based on his or her bowling skill level and number of strike frames bowled during a three game session, has an opportunity to successfully complete pre-identified bingo patterns for awards. All entrants pay a fee prior to their league bowling and receive one or more computer generated bingo cards, each containing a matrix of numbers that correspond to individual bowling frame numbers for their three game sessions. In addition, and as a means of equalizing opportunity (handicapping bowlers), free computer generated strike frames may be given on each entrant's bingo card based on the bowlers skill level. An algorithm has been developed which determines the number of free strikes awarded to equalize all skill levels. The number of free strikes given is determined by identified average bracket levels and the system precludes issuance of a winning pattern with free spaces.
