Abstract: COMBINATION LEFT AND RIGHT HANDED FURNACE ROOF                 Abstract of the Disclosure A combination left- and right-handed roof system adapted for use in electric arc or other furnaces having roof removal in either a clockwise or counterclockwise direction.  The roof system is spray cooled by a coolant and includes a coolant drain system divided into at least two segments and having opposing inlets for receiving spent coolant. Two pairs of adjacent coolant outlets are provided for connection with a coolant collection pump, depending upon the direction of roof removal, and each outlet in each of the pairs is associated with a different drain system segment.  A removable U-shaped conduit connects the two outlets of the pair disconnected from the coolant collection pump. Coolant may flow from one inlet, directly through a single drain system segment, and be removed from the roof through one of the connected outlets.  Coolant may independently flow from the opposite inlet, through the U-shaped conduit and another drain segment, and be removed from the roof through the other connected outlet.

Abstract: AUTOMATICALLY RESETTING PROTECTION ARRANGEMENT FOR A TELEPHONE SUBSCRIBER LINE INTERFACE CIRCUIT            Abstract of the Disclosure A protection arrangement for coupling a two-wire line to a SLIC includes surge protecting triacs between each wire and ground, and normally closed contacts coupling the wires to the SLIC.  The triacs are triggered via varistors coupled to the wires on the SLIC side of the contacts, which are opened in response to over-voltages on the line, as detected via a diode bridge and threshold circuit.  The triacs are thereby not triggered during over-voltage conditions so that their power dissipation is reduced during such faults, whereas they respond rapidly to surge conditions which accordingly need not be handled by the contacts.                     - i -

Abstract: In a drive mechanism of the type where a rotating drive wheel deforms and partly works into engagement with a rod of deformable material to axially displace the rod as the drive wheel rotates, the drive wheel is a wheel (15) which is provided with worm threads (17) and whose axis of rotation is substantially parallel with the said rod (11). According to the invention, such a structure results in an unprecedented great metering accuracy with indication of very small doses from e.g. an injection syringe (13) whose plunger (14) is driven by said rod (11). The invention is characterized in that the worm threads work into the deformable material of the rod under the action of essentially completely continuous forces. The preferred embodiment comprises two worms (in Fig. 4 behind the worm (17) on the opposite side of the rod (11) driven by their respective shafts (19), which are driven by a common worm (22) via helical toothed wheels (21). An antibackup roller (12) placed in an opening cover (27) serves to press the rod (11) down between the two worms so as to provide some wedge effect. Complete balance in the mechanism is obtained because the two worms rotate in the opposite direction.

Abstract: A reclosable extruded plastic fastener for joining sheet material such as walls of bags, and method of making the same. The fastener comprises a grooved female profile and a complementary hook-headed male profile, and a stabilizing structure especially advantageous when pressing the profiles together into closed fastener assembly. The female profile has a generally square base with at least one stop shoulder to minimize tipping of the female profile about a thin, thermal bridge minimizing, heat transfer limiting stem. The hooked jaw arms of the female profile may have various geometric shapes. The male profile has an interhooking barb which interengages with the hooked jaws of the female profile. Stabilizing ribs are spaced from the head, but the rib at the inner side of the head is closer to the head than at the other or outer side, so that there is a desirable differential fastener separating relationship retaining the fastener efficiently with greater hold against opening due to internal bag forces.

Abstract: This invention relates to formaldehyde-free, aqueous glue dispersions which contain polyisocyanates. These systems are particularly suitable for gluing veneers and surface materials on wood and wood products. The systems are prepared from polyisocyanates in combination with extenders based on flours and cold water-soluble of hydrolyzed natural starch. In this process, polyisocyanates or aqueous dispersions thereof are added while stirring to aqueous solutions or mixtures of starch and flour. The extender-containing adhesive systems are aqueous glue dispersions having increased service life which in their preferred embodiment contain about 15 to 30% by weight of polyisocyanates, preferably polyphenyl-polymethylene polyisocyanate (PMDI), 10 to 15% by weight of starch which is soluble in cold water and 14 to 25% by weight of (cereal) flour and optionally, other additives and the appropriate quantity of water adding up to 100% by weight. The glue dispersions are easily applied with glue spreading machines and if applied in suitable quantities do not bleed through veneers. The implements used for applying the glues can easily be cleaned by rinsing them with water. The invention is also directed to the use of the glue dispersions for gluing, particularly for gluing veneers or other surface coating materials to wood or wood products.

Abstract: The present invention concerns a process for stopping for a prolonged period and restarting a series of tanks for the electrolytic refining of copper. The process comprises preparing for the stoppage by reducing the proportion of Cu2+ ions in the electrolyte, controlling the additive agents, regulating the level of the electrolyte, and slow crystallization of CuSO4 in the form of very fine crystals. Subsequent restarting comprises restoration of the circulation of the electrolyte with progressive heating, a progressive increase in the electrolysis current strength, and resumption of the addition of additives. Use of the invention makes it possible to obtain deposits of refined copper of commercial quality as from the first electrolysis cycle.

Title: Retrofittable receptor device
Inventor: DAHOWSKI DONALD E
IPC: E04H4/14
Filed: 1989-11-14
Granted: 2000-01-18
Abstract: A longitudinal receptor construction for insertion into a channel or opening and for holding a desired element is provided.      The receptor has an inverted L-shape cross-section in which a horizontal leg is advantageously suited for retrofit usage in an existing groove or channel opening and has locking features which afford substantially improved capability for holding the receptor and the element inserted into the receptor. The groove into which the receptor is positioned may be the groove contiguous to a swimming pool coping arid may be the same groove devised for and used to hold another element such as the peripheral bead of a swimming pool liner. Sufficient gripping force by the horizontal receptor leg in the locking groove or channel is provided by the receptor leg configuration which prevents dislodging of the receptor leg by forces pulling on the receptor or other member which may be present in the opening. Advantageously the receptor may be used on an existing pool coping which has a channel or groove into which the peripheral bead of a vinyl liner which covers the swimming pool bottom is positioned. The securing leg of the receptor of the invention is of slender construction and contoured that it can be accommodated, together with the bead of the swimming pool liner, within a conventional pre-existing channel or groove such as that in the upper inner wall or coping of a swimming pool which houses the bead of a pool liner.
