Granted: 1993-10-25
Abstract: Two process (1) and (2A) and (2B) are claimed as is the cpd. in (ii) of process (1). (1) Process for repairing a multi-wire electrical cable after exposure to water resulting in water-bridging comprises (i) opening the outer covering; (ii) distributing granules of a water-swellable, water-insoluble polymer mixed with granules of a lubricating and bond-breaking substances into the interstices for a sufficient time to dry the insulation; (iii) removing the polymer granules; and (iv) restoring the outer covering. The cpd. in (ii) is also claimed. The polymer granules are pref. 50-150 mesh and have attached carboxylate, sulphate, phosphate and/or sulphonate gps. These granules cause no electrochemical heating. The lubricating and bond-breaking substances comprise pref. 70-90 vol.% and are pref. non-silica talc or clay. (2A) Process for electrochemically coating a metallic wire having a positive ionic deposition comprises (a) prepg. a soln. of a polymer having anionic gps. and at least one non-involved cationic substance; (b) placing the wire in the soln.; (c) passing a small DC current through the soln. so that the wire is the anode, and the substance with cations is left in soln. This provides a hydrophobic insulation which is chelated on the wire, with an anionic-cationic linkage established between the polymer and the metal. (2B) Above process is the basis of another claimed process for repairing a cable carrying at least one pair of wires, e.g. telephone wires, which carry a small DC current after a short caused by water. It essentially comprises sprinkling polymer granules having anionic gps. and at least one non-involved cationic substance over isolated and sepd. wires followed by passing a small DC current through the wire.

Title: Apparatus for separating labels from a perforated sheet
Inventor: KUNREUTHER STEVEN
IPC: B26F3/00
Filed: 1990-08-31
Granted: 1995-12-26
Abstract: Labels in sheet form are first separated into strips along spaced parallel perforation lines extending in the direction of sheet movement and then into individual labels along spaced perforation lines extending in a direction transverse to sheet movement.  The strip separation step can be accomplished with one of three ways.  The first embodiment includes a two driven pressure rollers one of which has a resilient exterior surface including discontinuous alternating larger and smaller diameter areas and the other has a rigid continuous surface of different diameter sections.  The rollers cooperate to clamp the sheet at points between the perforation lines as it moves and exert to a force along the perforating lines to burst same.  The second embodiment involves moving belts which clamp the sheets between the perforation lines as it moves, gradually separating into different planes.  The third embodiment includes a reciprocating element with fins and a pressure pad with slots aligned with the perforation lines to accomodate the reciprocating fins.  Transverse separation is accomplished by first and second spaced pairs of rollers.  The second pair of rollers is rotated at a higher speed than the first pair such that the labels are completely separated.  The individual labels can be accumulated on a slowly moving conveyor.

Title: Method for quenching silicon spent bed
Inventor: MARKO OLLIE W
IPC: C07F7/12
Filed: 1990-10-24
Granted: 2000-10-10
Abstract: The instant invention is a method for the quenching of a spent bed resulting from the reaction of organic halides with silicon metal to form organohalosilanes. The method employs a strong base and elevated temperature to digest the hydrophobic siloxane-rich coating and dislodge the carbon coating which forms around the spent bed particles. Removal of these coatings allows more rapid and complete quenching of the autoxidants on the surface of the spent bed particles.

Title: System and method for communications security protection
Inventor: SALTWICK JOHN M
IPC: H04K3/00
Filed: 1990-05-14
Granted: 1994-10-18
Abstract: A system and method are disclosed for pre-venting intelligible interception of information sig-nals transmitted over a two-direction line.  A masking signal is applied through a hybrid circuit at the receiving end of the line, and this masking signal, which appears on the line together with the informa-tion signal, prevents intelligible decoding.  The masking signal includes a series of frequencies which are sequentially applied.  Only at the receiving end of the line, where the hybrid circuit attenuates the masking signal which it receives at its receive port, can intelligible decoding take place.  The amplitude of the information signals is sensed at the receiving end and the amplitude of the masking signals on the line is adjusted to be great enough to provide security, by confusing an eavesdropping detector, yet small enough at the receiving end so that the receiv-ing detector is not confused.

Title: Microwave oven with invertor control power source
Inventor: MINAKAWA HIROSHI
IPC: H05B6/68
Filed: 1991-03-28
Granted: 1994-11-08
Abstract: A microwave oven with an invertor control power source produces a microwave by the use of a magnetron in combination with high frequency power generated by an invertor control power source.   Heat sensitive ferrite beads provided on a lead wire for transmitting the high frequency power to the magnetron changes the inductance of the wire from a high level to a low level at around a threshold temperature,  which is lower than the working equilibrium temperature of the magnetron.  As a result, the cathode  filament  current  remains  within the  allowable range, and moding of the magnetron is prevented.  Thus the lifetime of the magnetron is lengthened.

Title: Carrier stock with integral handles
Inventor: MARCO LESLIE S
IPC: B65D67/02
Filed: 1991-04-08
Granted: 1998-09-22
Abstract: Carrier stock formed from a single sheet of resilient polymeric material, such as low density polyethylene, and severable into individual carriers with integral handles.  For each carrier, integrally joined band segments define container-receiving apertures.  Moreover, an integral handle is joined at its ends respectively to middle portions of two outer segments, which are joined to one cross segment at a node.  Stresses are distributed from each end of the handle, through the outer segment having such end joined to a middle portion thereof, to two cross segments. Perforated lines divide alternate cross segments into half segments and facilitate severance of such stock to form the individual carriers.  Each half segment has an aperture-defining edge configured to provide means, which may comprise a nub, for countering tendencies of such half segment to neck down or to break.  The handle has a middle leg, which is joined to the node via a frangible joint, as defined by a perforated line extending across the middle leg.  The frangible joint is designed to break away when stressed.
