Title: Method for detecting warp threads clinging together, and a weaving machine that uses this method
Inventor: SHAW HENRY
IPC: D03D51/20
Filed: 1987-09-22
Abstract: Method for detecting the presence or absence of warp threads clinging together, with the characteristic that it consists principally of a combination of: initiating a machine stop when a warp stop signal is received indicating that a contact has been made by a drop wire 9; checking for a fallen drop wire 9A; and, if no fallen drop wire is found, restarting the machine at least once and interpreting the warp stop motion generated as a result of the restart as an indication that the warp threads 2 are clinging together.

Abstract: A tank fill assist (20) for filling a tank or other equiva­lent volume from a remote source of liquid, for example filling a consumer product (50) from a sink or bathroom faucet (148) with fresh water. The fill assist (20) is normally stowed within the interior of the tank (50). It is withdrawn for connection to a faucet (148) for tank filling, and is then returned to stowed position after tank filling. The fill assist (20) comprises standard flexible conduit (22) with unique inlet (124) and outlet (26) fittings at opposite ends. The outlet fitting (26) is disposed within the interior of the tank (50) and is constructed and arranged to prevent accidental separation of the fill assist (20) from the tank (50) when the conduit (22) is withdrawn from the tank (50) yet to allow passage through the fill opening when it is intended to either join or separate the fill assist (20) to or from the tank (50). The inlet fitting (124) is of thermoplastic rubber and can be fitted over the outlets of typical sink and bathroom faucets (146).

Abstract: Friedel Crafts preparation of arylene ether ketone polymers with an exceptionally high degree of isomeric purity and freedom from by-products can be achieved by adding to the Lewis acid reaction system a protic controlling agent selected from ROX, water, RCOOX, RSO 3 X, and ROY, wherein R is organic, X is hydrogen or metal, and Y is metal. Contrary to conventional expectation, the protic agent does not significantly acylate or alkylate the polymer, and agents of relatively low molecular weight, e.g. benzoic acid, can be selected to produce dispersions of the resulting polymers. The controlling agent also apparently acts to maintain the polymer in solution until a desired molecular weight is reached.

Abstract: A brush assembly 11 in a fractional horsepower PMDC motor comprises a cage 17 in which a brush 12 is slidable, the brush 12 being urged against a commutator 14 by a torsion spring 13. Power is supplied to the cage 17 and current passes through to the commutator via the brush 12. A leaf spring 26 is riveted 28 to the cage 17 and bears on the brush 12 to urge it against a base plate 19 of the cage 17. This reduces brush chatter and provides an electrical path between the cage and brush, reducing the current flow through the torsion spring 13 which otherwise tends to anneal the torsion spring.

Abstract: A pulse motor control apparatus for a polyphase excitation type pulse motor (6) variably and independently controls excitation currents supplied to excitation coils (41, 42). Ratios of any excitation current to other excitation currents supplied to the excitation coils (41, 42) are changed stepwise to rotate a composite magnetic field vector forward by those excitation coils (41, 42) each multiple of a real number of a predetermined unit angle at one time for controlling the rotational angle of a rotor of the pulse vector. The pulse motor control apparatus assures fine control for the rotational angle of the rotor compared with prior cases where currents supplied to a plurality of excitation coils (41, 42) are switched on and off for rotational control. Application of the present control apparatus to printers, etc., precludes replacement of gears, etc., due to types of print heads mounted thereon. Additional advantages such as inprovement of a torque ripple upon driving the pulse motor assure extensive application to various fields.

Abstract: A semiconductor process for fabricating bipolar devices of one type and extendible to include bipolar devices of a second type in the same epi-layer. The process protects selected surfaces of the epi-layer against deleterious processes associated with the formation of future emitter/contact regions for the devices. Subsequently, such emitter/contact regions are formed beneath such protected surfaces and contribute to enhanced device performance. The process also provides improved planarization of an insulating layer on the epi-layer by chemical-mechanical polishing. The planarization in conjunction with a mask formed in the insulating layer facilitates the formation of self-aligned emitter/base regions to appropriate thicknesses for high performance devices.
