Abstract: TECHNIQUE AND APPARATUS FOR MEASURING THE VALUE OF A CAPACITANCE IN AN ELECTRICAL CIRCUIT SUCH AS A TELEPHONE COMMUNICATION LINE     BSTRACT OF THE DISCLOSURE          A technique for measuring the value of a capacitance that is inseparatably connected with other circuit elements as part of a composite electrical circuit.  The measurement is insensitive to such other elements that include resistances, inductances and active voltage sources.  The technique involves the charging of the unknown capacitance followed by an immediate transfer of that charge to an external known capacitance that is part of an integrating circuit.  The voltage stored by the known capacitance is unaffected by series resistances and is proportional to the desired electrical circuit capacitance being measured.  The effect of induced or generated interfering signals in the circuit are cancelled by transferring the charge to the known capacitor for a period equal to an integral multiple of periods of the interfering signal.  Furthermore, the charging voltage is adapted to the particular circuit in order to compensate for any resistance shunting the capacitance being measured.  These techniques have a particular application to capacitive measurements of telephone communication lines.

Abstract: ABSTRACT OF THE DISCLOSURE            A water lubricated rubber bearing is disclosed in which a compliment of staves is positioned within a bearing housing having a cylindrical inner bearing housing surface.  When unstressed, the stave can be moved within the housing for installation or removal.  Locking of the staves in the assembly is provided by producing tight frictional contact between the inner bearing housing surface and the exterior surface of the staves.  Such locking frictional contact is produced by axially compressing the staves to increase their thickness and to produce tight frictional contact between the outer surface of the stave with the bearing housing along the entire length of the staves.  Additional locking is provided at the ends of the staves by pins mounted on the housing assembly, which project into bores within the ends of the staves.  Such pins augment the fritional locking at the ends of the staves to resist peripherally directed movement of the stave ends.          Each stave illustrated consists of two aligned and abutting stave elements providing cylindrical openings at their ends, which receive bridging alignment pins to insure that the stave elements are aligned in the assembled condition.

Abstract: ABSTRACT OF THE DISCLOSURE A pre-cured tread stock for re-capping a vehicle tire and a method for retaining the tread tightly in place on the peripheral surface of the tire casing during the curing of the tread onto the casing under heat and pressure.  The tread cross-section includes a central portion and a longitudinally extending groove at each side near the respective edge or "wing", the grooves extending circumferentially around the tire casing when the tread is wrapped around and "stitched" to the casing.  The grooves are of such shape that when the tread is laterally curved to fit a buffed tire casing, the outer and-lower sides of the grooves extend generally upwardly in a hook-shaped profile.  The method includes the steps of (1) placing a retainer around the tread-stock in each of the grooves after the tread stock is wrapped around and stitched to the tire casing; (2)  alternatively, (a) reducing the dia-meter of substantially inextensible retainers such as steel wire by tightening them against the outer sides of the grooves to squeeze the wings of the tread radially inwardly relative to and tightly against the casing and to hold them in place during the curing or (b) using resilient loop retainers which are expanded, laid in the grooves and then retract to squeeze the wings against the casing or (c) using retainers made of a material which shrinks upon heating so as to even more tightly squeeze the tread wings against the casing at the start of the curing process; (3) curing the tread stock to the casing; (4) removing the retainers after the assembly is cured and; (5) buffing or cutting off the hook-shaped material forming the lower sides of the grooves.

Abstract: CIRCUIT BREAKER WITH OPERATING MECHANISM      HAVING OUTBOARD CAM AND RATCHET     ABSTRACT OF THE DISCLOSURE         A circuit breaker is taught having an operating mechanism with two parallel, spaced apart support members.          A circular shaft having keyed ends is supported in the parallel support members such that the keyed ends extend outboard of the two support members.  On one keyed end is disposed a correspondingly keyed cam.  On the other keyed end is disposed a ratchet wheel which is spaced from the keyed portion so that it may turn independent of the shaft in one direction.  Also disposed on the same end as the ratchet is a correspondingly keyed lever which rotates synchronously with the cam.  The lever may interlock with the ratchet to be rotated thereby.  Both the lever and cam have parallel connecting rods extending therefrom which are perpendicular to the shaft and generally parallel to the support plates. The rods are attached at one end thereof to a closing spring yoke.  A closing spring is provided between the yoke and a fixed member which is perpendicular to and supported by the previously described support members.          Rotation of the ratchet in the proper direction causes movement of the connecting rods for compressing or charging the contact closing spring.  Correspondingly, discharge of the spring moves the connecting rod to rotate the cam.  The cam is interlinked by way of a cam follower to a jack shaft which in turn is interconnected with separable main contacts for opening and closing the contacts.  A separate opening spring is interconnected with the jack shaft for the opening operation.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved method of interconnecting the frame or rail members of a sash.  In the case of conventional horizon-tally sliding sashes, each sash member comprises an upper and a lower rail member, a pair of side rail members.  Ends of the upper and lower rail members are inserted into the ends of the supporting channels of the side rail members, and are retained therein by means of self-threading screws.  The present inven-tion eliminates the use of screws as fasteners for retaining the rail members of the sash in assembly.  The improved joint construction comprises a first rail member and second rail member, the former having a pair of spaced-apart parallel outer walls interconnected by a web portion extending the length thereof.  The inner portions of the outer walls together with the web define a sash glass supporting channel extending along a length of the first rail member, the web having a protuberance extending inwardly into the channel.  The second rail member has spaced-apart parallel outer walls interconnected by a C-shaped web portion defining an arcuate expandable socket.  A cut-out portion is defined by an area in which indentical wall portions of both outer walls of the second rail member have been removed.  Parallel edges of the cut-out portion, which are spaced apart a distance corresponding to a distance be-tween the outer surfaces of a pair of inwardly directed pro-jections situated on inner surfaces of outer walls of the first rail member, frictionally engage the outer surfaces of the pair of spaced-apart projections of the first rail member as the second rail member is slid into tight engagement with the first rail member, and the lower end of the arcuate expandable socket engages a protuberance in the web of the sash glass supporting channel of the first rail member, whereby the first and second rail members are retained in locked assembly.
