Abstract: ABSTRACT           A method and apparatus for sensing the oscillating state of an oscillating system in a transmitter and for delivering energy to the oscillating system for maintaining the oscillation in the oscillating system.  In order to measure a function, such as pressure or change of length, at least one frequency determinative parameter in the oscillating system is designed to be reacted upon by the selected function and a signal representative of the change in frequency is sensed and measured. The sensing of the oscillations is effected along the same signal path as that used to deliver the necessary energy to maintain the oscillation in the system.  The oscillating system may be either mechanical or electrical.

Abstract: SET SEPARATOR     ABSTRACT OF THE DISCLOSURE A  set separator for offsetting sets of sheets of paper is provided.  A first set of paddle wheels is provided which, in one position, directs a sheet of paper forwards towards a stop wall and to one side, and in a second position directs the sheet of paper forwards towards the wall and to the opposite side.  A pair of sideposts is spaced apart more than the dimension of the leading edge of the sheet of paper so that only one post is engaged by one side edge of a sheet of paper, when the paddle wheels are in the first position, and only the other post is engaged by the opposite side edge of a sheet of paper when the paddle wheels are in the second position.  The sideposts rotate in directions opposite to one another to move the sheet forwards toward the wall.  A second pair of paddle wheels, also spaced apart more than the dimension of the leading edge of the sheet of paper so that only one paddle wheel engages the sheet of paper at a time, is located adjacent the stop wall.  The second pair of paddle wheels rotates in directions opposite to one another about axes which extend in the same general direction that the sheet of paper moves.  A particular one of the second pair of paddle wheels engages the sheet of paper at a particular time to urge the paper in the same side direction that the first pair of paddle wheels is urging the sheet.  The second pair of paddle wheels acts to keep the sheet from riding up the wall.  The first pair of paddle wheels is in one position until the required number of sheets are received to make up one set.  Then the first pair of paddle wheels is changed to its other position to direct the sheets of another set toward the opposite side of the separator to laterally offset the sets from one another.

Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates to a method for terminating insu-lated conductors in respective insulation-piercing contacts of an electrical connector.  Prior art terminating machines are rather complex and expensive, and manual insertion becomes an extremely slow and expensive process when it is necessary to terminate a large number of conductors, particularly as a continuously repe-titive operation.  The present invention overcomes these defects of the prior art by providing the technique of supporting the con-nector on a base with the conductor channels exposed to receive the respective conductors, and moving an insertion tool generally parallel to the connector to sequentially insert the conductors within the respective channels and insulation-piercing contacts.          The connector may comprise a notched ridge, with each notch in communication with a respective channel for alignment before insertion.  The entire terminating apparatus to carry out the method resembles a credit card impression mechanism with a wheeled carriage supported to traverse a base in opposite directions.  In one embodiment, a wire cutter, supported by the carriage, advances in front of the insertion tool to cut the ends of the wires before insertion, thereby performing the insertion operation upon return of the carriage.  In a second embodiment, the insertion tool includes the wire cutter and operates to cut the wires contempo-raneously with insertion.  In another embodiment, a wire cutter is carried between a wire pulling and seating member and the in-sertion tool, whereby the individual wires are snugged in each channel, and then cut to a predetermined length before insertion.     .

Abstract: DOUBLE SASH STRUCTURE          Abstract of the Disclosure A window frame assembly ready for securement in a window opening of a building to provide a double sash window structure comprising a first sash facing to the outside and a second sash facing to the inside.  The window frame portion supporting the first sash is formed of a metallic material and that of the second sash is formed of a synthetic resin material having a low heat conductivity.  The latter is disposed contiguously to the window frame of the first sash.  The two frame portions are secured to each other by interlocking complementary engagement means, preferably prior to the mounting of the frame within the window opening of a building.  By virtue of the low heat conductivity of the window frame of the second sash, lowering of the temperature in the room and formation of dew by condensation of moisture can be reduced.  The invention thus provides an improved double sash structure excellent in the heat-insulating property, having an attractive appearance and an improved strength, combined with an easy assembly of the two frame parts.

Abstract: ABSTRACT              Liquid coolant and lubricant is intermittently pressure fed through a hollow drill stem to the tip of a drill, preferably a spade drill, against the workpiece by compressed air from the conventional machine shop air line which is fed over and released from a column of the liquid coolant and lubricant at selected frequencies and for selected durations without the use of motors, pumps, or other propelling devices. A pair of manually adjusted controls select the frequency of intermittent coolant feed and the length of feed duration within the selected frequency to maintain desired operating temperatures at the drill tip while effectively flushing out chips cut from the workpiece.
