Abstract: A detection circuit for remote release apparatus is disclosed which monitors a circuit carrying high-voltage between two connection points A and B and disconnects the circuit from the rest of a high-voltage network by automatically opening two power switches when a short circuit is detected. The ground fault protection system includes a pair of power switches for disconnecting points A and B from the remainder of a high-voltage network when a fault is detected in the high-voltage carrying circuit. A different one of a pair of detection circuits are associated with each point A and B. Each detection circuit causes both power switches to open when a fault is detected. The fault detection circuit associated with point A detects faults occurring in the high-voltage carrying circuit at any location extending from point A to at least one-half a distance to point B. The detection circuit associated with point B detects faults occurring in the high-voltage carrying circuit at any location extending from point B to at least one-half the distance to point A.

Abstract: A spot-type disc brake unit which cooperates with a brake disc when in use to form a disc brake includes a brake shoe carrier member and at least one brake shoe carried by the carrier member for axial movement toward and away from the brake disc, and with freedom of limited circumferential displacement upon entrainment of the brake shoe by the brake disc during the braking operation. The brake shoe includes a lining having a friction surface facing toward the brake disc and a backing plate rigid with the lining and having a backing surface facing away from the brake disc, as well as disc entry and disc exit, substantially circumferentially facing, end surfaces. A braking-force bell crank lever is arranged at least at the disc exit end surface of the backing plate. The lever has a first lever arm which extends into the path of circumferential displacement of the brake shoe, and a second lever arm which extends into juxtaposition with a selected region of the backing surface to apply an additional augmenting axial force to the brake shoe at such region. The lever has a fulcrum portion which engages an engagement surface of the carrier member to constitute a pivot axis for the lever therewith during the braking operation. Upon termination of the braking operation, the lever is attracted by a spring to the backing plate to compensate for the diminishment of the thickness of the lining attributable to the wear of the latter.

Abstract: A dewatering press section for a paper or cardboard web includes a press roll having a wide pressing zone over which a belt is provided to run guided by guide rollers with the web being arranged to run in the pressing zone in compression between the press roll and the belt. At least one fabric runs in the pressing zone and acts on a respective face of the web. A pressure transmitting device has a surface which overlies the belt substantially in the pressing zone. According to the invention, ultrasonic field generators are provided in association with the pressure transmitting device surface for applying an ultrasonic field substantially in the pressing zone such that the friction between the surface of the pressure transmitting device and the belt is substantially reduced. The ultrasonic field generators can operate at a single frequency, at a plurality of discrete frequencies or may emit a continuous spectrum of frequencies and the intensity of the ultrasonic field is selected such that in addition to reducing the friction between the belt and the surface of the pressure transmitting device, the ultrasonic field will also substantially promote the removal of water from the web within the pressing zone as well as the transfer of water removed from the web into the press fabric or fabrics.

Abstract: At least one algae-produced, substantially pure chemical compound with biocidal activity has been isolated from a blue-green algal (Cyanobacteria) toxin, preferably Scytonema toxin. This biocide appears to be one of the first of its class, since very little is now known regarding algal toxins and any biocides (including any antibiotics) they may contain. A biocide of this invention has activity against harmful blue-green algae such as Anabaena and can be used as, among other things, an algicide with minimal undesirable effects upon the environment of use (e.g. lakes, streams, water supplies, swimming pools, etc.). An ether-soluble, nonsteroidal, anisole-containing biocide of this invention appears to have a molecular weight of 430 or 431, a melting point or range within the range of about 48 DEG  to about 55 DEG  C., and the empirical formula C23H23O6Cl. Other groups in the molecule besides the anisole appear to include a saturated gamma-lactone, an aliphatic OH, a methylene bridge, a chlorobenzene ring, and an isopropyl substituent (probably attached to the gamma-lactone) in an asymmetric environment. The compound can be stored in or crystallized from diethyl ether and blended with the usual pharmaceutical extenders.
