Abstract: The invention relates to an arrangement for the stripping of layers of pieces of timber (3), in particular boards and planks, comprising a lift arrangement (1) that, inclined at an angle to the horizontal plane, supports a stack of timber (2), a transport element (17) that is located above the stack of timber and strips one layer at a time through interaction with the uppermost layer of timber in the stack of boards (2) perpendicular to the longitudinal direction of the boards, whereby the stripped layer of boards is delivered to a subsequent transporter (10). According to the invention, the endless mobile transport element (17) is placed in connection in a manner that transfers motion with a driving source with which the transport element can be transferred between a stopped position at which it is essentially locked against motion and an active operating position in which it is active, whereby the layer of timber is retained on the stack of timber (2) through interaction with the transport element when it is in its stopped position.

Abstract: 1494136 Automatic exchange systems TELEFONAKTIEBOLAGET L M ERICSSON 26 Feb 1975 [6 March 1974] 8111/75 Heading H4K In an exchange system in which a subscriber makes an enquiry call, e.g. to initiate an interim conversation with a third party, by earthing one of the speech wires La, Lb, e.g. by depressing a key K at his substation TA, this earthing is detected at the exchange by a circuit DA which includes voltage dividers R5, R6 and R3, R4 and a differential amplifier DF. The resistors R3-R6 are chosen so that for on-hook (no current in La, Lb ) and connection-established (equal currents in La, Lb) conditions, the output from DF, Fig. 2 (not shown) is substantially zero. However, on depression of key K the currents in La, Lb become unequal, resulting in a negative output from DF. This output actuates a coupling circuit, which brings about the necessary switching sequences for an enquiry call.

Abstract: To protect a discrete electronic component such as a bipolar transistor or a field-effect transistor against destructive current surges, one or two ancillary transistors are formed in the same semiconductor body which has a major portion thereof overlain by an output electrode constituting a variable-voltage terminal connected to a load. This major portion, acting as the collector of the bipolar transistor (or of two such transistors in a Darlington configuration) or as the drain of the FET to be protected, also forms the collector of each ancillary transistor whose emitter is grounded through a constant-current generator or through a resistor. The emitter potential of a single ancillary transistor, or the potential difference of the emitters of two such transistors of mutually different current densities, varies as a function of temperature and is compared with a reference voltage to apply, in the event of an overload, an inhibiting signal to a driver stage for blocking or limiting the conduction of the protected component.

Abstract: A battery interseparator useful in alkaline battery systems, and a process of forming the same, is formed from a composition having 30-70% by weight synthetic pulp, 15-65% by weight alkali resistant inorganic filler, and 1-35% by weight of long fibers having lengths of between 1/4 and 1 inch. The long fibers may be polyester, polyacrylic, polyamide, polyolefin, or other staple fiber material. The process for forming the subject battery interseparator requires first forming a substantially uniform aqueous mixture of the subject composition, sequentially treating said composition with a combination of a cationic and an anionic agent, applying the treated composition to a standard paper-making apparatus at a grammage rate to cause the resultant dried sheet to have a thickness of less than 10 mils, and forming a sheet product.

Abstract: This invention pertains to an impact wrench mechanism and a clutch therefor, wherein a motor having an output shaft rotatably drives a carrier member mounted on an axis. Anvil jaw(s) rotatably and coaxially mounted adjacent the carrier member have impact jaw(s) extending radially therefrom. Hammer member(s) having impact jaw(s) for impacting with the anvil jaw(s) is (are) mounted on the carrier member for rotation therewith and for limited linear motion relative thereto in a direction essentially transverse to the axis of rotation to allow the hammer member impact jaw(s) to contact the anvil jaw(s). The line of force of the impact blow has a force component tending to urge the hammer member(s) out of engagement with the anvil jaw(s), but the hammer member(s) have a mass and a mass center location such that linear inertial force is created which prevents motion of the hammer member(s) during the impact blow.

Abstract: A self-converging deflection yoke having toroidally-wound vertical deflection coils incorporates a pair of magnetically permeable field formers mounted on either side of the yoke. The field formers shunt a portion of the external field flux to the vicinity of the electron gun assembly where they form a pincushion-shaped field which aids in vertical coma correction. In one embodiment, a yoke comprising planar-wound vertical coils incorporates both coma-correcting rear field formers and a pair of front crossarm assemblies for providing side-pincushion correction. The resultant yoke provides covergence of electron beams free of coma and side-pincushion distortion with reduced sensitivity to transverse motion. In another embodiment, similar results are obtained without the front crossarms by vertical deflection coil having a nonradial winding configuration.

Abstract: The present invention pertains to a composite material from parts of a plant origin, for example, from wooden elements, veneers, chips, sawdust, bark, corn cobs, stalks and straw, containing lignocellulose materials with the content of polysaccharides, lignin, tannins, essential oils, which parts are bound together in the said composite material. The invention consists in application of an activation agent, for example, sulfuric acid, on the parts of starting material, which causes transformation of the polymeric compound of parts to an active monomer. An excess of activation agent is neutralized, if it is desired, by addition of a neutralization agent, for example, powdered urea. The activated parts are then put together and compressed under heating, to cause crosslinking of the activated monomer to a polymeric compound of similar character as is the original polymeric compound and thus bind the parts together. The activation effect can be increased by addition of a catalyst, for example, potassium permanganate. The binding effect of the binder generated from the lignocellulose material may be increased by addition of furylalcohol, furylaldehyde, furylacetone, phenols, or their precondensates or thermoplastics.
