Abstract: LINE PROTECTOR FOR COMMUNICATIONS CIRCUIT            Abstract of the Disclosure A line protector for communications circuits com-prises a gas tube having external contact surfaces for connections to communication lines and to ground.  A conduc-tive member is proximate to the contact surfaces that are associated with the communication lines.  A dielectric sub-stance interposed between the conductive member and the last-mentioned contact surfaces melts upon overheating of the protector resulting from the excessive line current.  The conductive member, due to its resiliency, engages the subja-cent contact surface or surfaces thereby resulting in a direct short circuit between the protected line and ground.  A shield over at least part of the gas tube in the region of the con-ductive member prevents potting compound or foreign matter from obstructing the function of the conductive member.

Abstract: Abstract of the Disclosure A sprayer wherein there is formed in a sprayer body a pressurizing cylinder defining a pressurizing chamber communi-cating with a pressure accumulating chamber defined by a pressure accumulating cylinder in which a valve rod is slidably received. The pressurizing cylinder has a smaller diameter than the pressure accumulating cylinder. A piston is slidably inserted into the pressurizing cylinder. When a liquid received in the pressurizing chamber is pressurized by bringing down the piston in the pressurizing cylinder of the smaller diameter, then a higher pressure than the pressing force of the piston is applied by Pascal's principle to the valve rod against the urg-ing force of a pressure accumulating spring disposed behind the valve rod, because the valve rod has a larger diameter than the piston. When the high pressure is applied to the pressure accumulating spring, then a highly pressurized liquid can be sprayed, though the piston itself applies a relatively low pres-sing force and since the pressure accumulating spring is received in the pressure accumulating cylinder of the larger diameter, a spring having a large capacity of accumulating pressure can he used for accumulation of pressure.

Abstract: ABSTRACT OF THE DISCLOSURE      A vegetable peeler with a handle supporting a cylindrical and electrically rotatable shafted cutter body connected to the handle with a plurality of spaced cutter blades extend-ing longitudinally from the outer to the inner end of the body and a fixed splatter shield partially surrounding and spaced from the body and supported directly on the handle.          In this general arrangement there is provided an improved cutter and shield release assembly of a cylindrical tapered support surface on the handle and a matching tapered support surface on the shield for telescopically locking the parts together.  A cam and slot connection between the surfaces of different sized pins entering cooperating angled slots cams the tapered surfaces together and locks them. The body has a flared inner end and an abutment is provided on the shield adjacent the flared end so rotation of the shield breaks the tapered connection while simultaneously abutting the body to release the cutter without handling it.  The invention is thus directed to an improved cutter and shield release assembly for a vegetable peeler.

Abstract: Abstract A seal is used to prevent the escape of gas from a gas pressurized plastic-jacketed, multi-conductor cable where the conductors of an unjacketed portion of the cable enter a cabinet of a terminal which is exposed to temperature cycling.  The seal includes a sleeve made of an elastomeric material having one end which engages an end section of the cable jacket with the conductors of the unjacketed portion of the cable extending through the other end of the sleeve into the cabinet.  The seal also includes a metallic tube which is disposed about the elastomeric sleeve with one of the end portions of the tube which is aligned with the cable jacket being in compressive engagement with the sleeve and jacket.  A plugging compound in the other end portion of the tube and which is compliant with the sleeve material encapsulates the conductors and the other end of the sleeve which extends into the plugging compound.  The compliancy of the sleeve and the plugging compound cause them to move together during temperature cycling to avoid the development of leak paths and the escape of gas from the cable.

Abstract: Abstract method of restoring the shroud of a turbine blade which has become worn, and particularly that edge of the snroud in the vicinity of what is commonly known as the Z-notch, which comprises the steps of grinding down the shroud in the vicinity of said notch to an accurately pre-determined dimension with respect to the original geometry of the shroud, placing the blade in a fixture having a masking member with a slot in it, such that the Z-notch of the blade is disposed substantially in alignment with the slot, and de-positing, by means of a plasma spray, a metal alloy onto the edge in an amount just sufficient to build up the same essen-tially to its original dimension.  Following the plasma spraying, the built-up edge is sintered at a temperature on the order o_ 1900° F or more, to more firmly bond the built-up layer to the base metal.  The blade is then cooled.    The advantage of the present method is that it is especially inexpensive to carry out, while at the same time providing a re-furbished component which meets the stringent dimensional and physical specifications for a new part.  Moreover, since the resulting edge conforms so closely to the original geometry of a new blade, no additional refinishing or grinding operations are normally required after the sintering.

Abstract: 769.001 S P E C I F I C A T I O N               GKP       VARIABLE TRANSFORMER METHOD & APPARATUS             Inventor : Stanley G. Peschel ABSTRACT OF THE DISCLOSURE     In a variable transformer, two high-conductivity brushes are mounted in carriage means and adapted for longi-tudinally traversing the transformer winding to contact ex-posed segments of the winding which are relatively elevated with respect to portions of the nearby turns.  By relatively elevating and exposing the odd and even turns along two dif-ferent traverse paths contact with the individual odd and even¦ turns is obtained by the dual brush system without short-cir-cuiting adjoining turns, the brushes being interconnected through an external current-limiting or compensating circuit.          Spacings between exposed segments of the winding along these respective traverse paths are filled with dielectric potting material and are wider than the high-conductivity brushes; thus these brushes can never short circuit adjacent turns.         The brushes are positioned in the carriage relative to each other and relative to exposed winding segments so that at all times at least one of the brushes contacts an exposed winding segment.  Potential differences between exposed winding seg-ments contacted by respective brushes are offset by the volt-age difference compensating circuit, such as a diode circuit, connected between the brushes, whereby no turn-to-turn current can flow, irrespective of the external load conditions being applied to this compensating circuit.  Preferably, the wind-ing or windings are of copper wire having a square or rectangular cross section, and the high-conductivity brushes are also formed of copper.   Further, the winding or windings are advantageously closely coupled to the magnetically per-meable core of the variable transformer, thereby minimizing leakage flux and associated leakage reactance.  Very large size variable transformers now become feasible by employing this invention.
