Abstract: ABSTRACT     Endless Forms Feed Tractor Belt and Method of Making A forms feed tractor belt includes drive members molded around a thin, flexible band at longitudinal intervals.  To make the belt, slots are first punched at longitudinal intervals in at least one side of the flexible band. Drive members are then molded around the band at the slots except for at least one drive memberless interval at each end of the band.  The ends of the band are overlapped so that the slots of the drive memberless intervals coincide.  Final drive members are then molded around the slots of each pair of coincided drive memberless intervals to complete the endless tractor belt.

Abstract: PROPAGATION OF NETWORK QUERIES THROUGH   SUPERIOR SUBORDINATE AND PEER-PEER   DATA DISTRIBUTION RELATIONSHIPS     A directory database system includes a network and a plurality of directory service units (DSU), each of the DSUs providing one or more directory service functions within the directory database.  For propagation of an undirected user query relative to an object in the database from a source DSU to one or more target DSUs, one of which may contain information relative to the object, a propagation (P) table is provided in each of the DSUs, the P tables being a data structure capable of determining which other DSUs to send the user query to.      The source DSU examines its associated P table for the directory type specified in the query to generate an identification of one or more additional target ones of the DSUs to which the query should be directed.  After propagating a query from the source DSU to those additional DSUs identified by the P table in the source DSU, there is returned to the source DSU information responsive to the user query from the one of the additional target DSUs containing the information.

The machine includes a multi-station locking unit of horizontal or vertical configuration designed to hold a number of molds and an injection unit associated therewith for the simultaneous injection of the molds.  The machine also includes two outer mold clamping plates, one of which is mounted on guide elements and movable thereon in the locking direction and a center mold-receiving part movably mounted on guide elements between the two mold clamping plates and having a heatable melt conduction system with sprue nozzles and one half of a mold attached to each of its sides.  The center mold-receiving part is designed as a mold clamping plate sectioned lengthwise relative to the locking direction for receiving larger halves of a mold, the two parts of the plate being kept together by a high-speed clamping device and having the melt conduction system mounted between each other.          Separate driving cylinders are attached to the center mold clamping plate.  The melt conduction system has one or a plurality of separate melt conduction rails, each of which is rigidly clamped at its face side lengthwise relative to the direction of flow between the sectioned mold clamping plate so that uniform injection of both molds is assured regardless of expansion of the melt conduction system during heating.

Abstract: ABSTRACT OF THE DISCLOSURE            A technique for locating the position of a boring device within the ground with respect to a particular reference location along an above ground path directly over the intended course to be taken by the boring device is disclosed herein.  This technique utilizes an electro-magnetic field which is emitted from the device and an above-ground arrangement for simultaneously sensing the strength of the field at a number of distinct points.          The particular sensing points are selected so that the arrangement never has to leave the path directly above the boring devices intended course to locate the boring device, even if the latter deviates laterally from the path.

Abstract: Abstract of the Disclosure Finely divided ore blends containing chemically active magnesium oxide and calcium oxide are physically combined with a critical amount of water prior to reaction with acetic acid.  Intermediate products range in physical consistency from putty-like masses to viscous liquors, defending upon the relative fraction of magnesium oxide in the ore feed.  Intermediate products freeze to form hydrates of magnesium calcium acetate, the freeze times being dependent upon a number of chemical and physical parameters. Product drying requirements range from minimal drying to none at all, depending upon the magnesium fraction in the products.  Products are non-friable  and have excellent crush strength, and are suitable for storage, shipping and aplication in chemical deicing as well as other end use aplications where crude low-coat materials are called for.        A unique situation centers around the composition corresponding to the magnesium mol fraction of 0.8.  This material requires no drying and exhibits an extraordinary high crush strength.  Additionally, as much as 75% by weight of traction agent (sand) can be successfully incorporated into this material without the aid of chemical binders.

Abstract: An arrangement for the sealing of a shaft (2) which passes through a plate (1) which separates the "wet" and the "dry" zone of a packing machine from each other. In packing machines great demands are made on the tightness and durability of such shaft bushings, especially against strong washing agents, and the sealing assembly in accordance with the invention, therefore, has a flexible connection with the plate (1) and two O-rings (9,10), which are partly enclosed by the two halves of the sealing assembly and thereby are protected during washing as well as during operation. This design also produces a good sealing effect when during operation the shaft moves a little in radial direction.
