Abstract: ABSTRACT OF THE DISCLOSURE        A device for attachment of coil ends in a generator stator high-voltage winding, comprising insulation spacers disposed on external surfaces of the coil ends, auxiliary spacers disposed between coil end bars, a case, spring stops anchored inside the case, and planks.  The case is made of two coaxial truncated-cone members and a part of a torus member made integral therewith and incorporating a joint with a seal.  Each plank is arranged between two insulation spacers, and the insulation spacers are arranged between the coil end bars and the spring stops.  The insulation spacers, the planks, the spring stops and a side surface of the case form cooling passages.  The device according to the present invention permits saving electric energy by vir-tue of linger periods between overhauls provided due to higher dependability of attachment of the high-voltage winding coil ends and improved cooling thereof.

Abstract: -13-                RCA 74,513 Abstract A bidirectional pulse generator for driving a video disc stylus deflector.  Responsive to a deflection pulse a charge integrator has its input connected to a polarity selectable current source.  The integrator generates a ramped potential output signal having an amplitude proportional to the deflection pulse width and a slope related to the current polarity.  Upon termination of the deflection pulse a feedback loop is closed around the integrator to rapidly reset the output potential of the integrator to one of two pre-pulse output amplitudes.  A direction control selects the current source polarity and controls the pre-pulse output amplitude and thereby the relative polarity of the output pulse.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of producing pressure tubes for use in heavy water reactor, advanced thermal reactor or the like.  The method includes the following two steps conducted at the final stage of the production process for producing the pressure tube:          (1)       step of effecting a grinding on over the entire inner surface of the tube or on the inner surface at the end portion of the tube; and (2)       step of treating the ground tube in an auto-clave of hot water to form an oxide film.         By adopting these two additional steps, it is possible to avoid the delayed hydrogen cracking which is liable to be caused by the sand particles embedded in the tube surface during the production of the tube blank.

Abstract: REPLACEABLE ADJUSTABLE BUTTERFLY VALVE SEAT          Abstract This invention concerns a butterfly valve having a resilient, adjustable body seat for the pivoting disc.  The seat comprises a T-shaped elastomeric ring which is confined at one end by the transverse wall of an annular groove in the valve body and that another end by a clamping ring which slides along the wall of the flow passage extending through the body.  The clamping ring is forced against the seat ring by a plurality of individual screw actuators spaced around its circumference and therefore selected portions of the seat ring can be compressed as needed to produce a leak-free seal around the entire periphery of the pivoting disc.  The T-shaped elastomeric ring is held in place solely by mechanical forces in order to permit removal, maintenance, and replacement thereof.

Abstract: G. Domhan et al 4-15-5 (Revision) Abstract of the Disclosure A switch machine which is connected by two throw rods to the respective switch points to be operated includes an internal locking arrangement which includes two holding ele-ments pivotally mounted on the respective throw rods and accommodated between a sliding member and a displacement member of the switch machine which are disengageably connected to one another.  Each of the holding elements has a free end which is enlarged by two tongues respectively extending toward the sliding member and the casing of the switch machine. Depending on the position of the sliding member, the tongues are received in the associated recesses in the sliding member or in the casing to thereby either lock the throw rods in their positions relative to the casing or to entrain the same for movement with the sliding member.  During trailing of the switch points, the connection between the displacement member and the sliding member is discontinued so that the sliding member can move with the holding elements and the throw rods relative to the displacement member which is arrested in its position.  This connection is re-established during the subsequent throwing of the switch.            PRR:lgm

Abstract: ABSTRACT          The invention is concerned with a protective composition for application to a porous substrate, which comprises a protective material for protecting the substrate from deterioration and a carrier therefor, the  carrier comprising a hygroscopic liquid.  In a preferred embo-diment, the hygroscopic liquid used is ethylene glycol or a hygroscopic derivative thereof.  Particularly suitable protective materials are boron-rich compounds which are to be carried into wood as preservatives for suppressing or preventing insect or fungal attack.  It has been found that the glycol carrier penetrates the outer portion of the wood more quickly than an aqueous carrier.

Abstract: ELECTRONICALLY ACTUATED BRAKE SYSTEM        ABSTRACT           A pulse width modulated control signal is applied to inlet and outlet solenoid valves in a closed fluid vehicle brake system.  The electronic actuating circuitry can control a fluid brake system in a towed vehicle from a towing vehicle without fluid connections therebetween.  The closed fluid brake system provides an electrical feedback signal that tracks an electrical command signal applied by the towing vehicle operator through a manually operated command signal transducer to produce an error signal to maintain a command pressure in the towed vehicle fluid brake system.  The inlet and outlet valves are repeatedly opened and closed in accordance with the width of a train of pulses.   The pulse width is proportional to the difference between an electrical command signal and an error signal.

The substituent groups may be removed from the (substituted)-2-carbamoyloxypenams or the (substituted)-3-carbamoyloxycephams to give the corresponding free 2-carbamoyloxymethylpenams or 3-carbamoyloxycephams, respectively.  Novel penams and cephams provided by the present invention (after removal of the carboxyl-protecting group to produce the free acid) are active against various Gram-positive and Gram-negative organisms and, accordingly, are useful antibacterial agents for the treatment of diseases caused by such organisms in animals, including man.
