Abstract: AN APPARATUS FOR REMOVING FLASH FROM  THE INSIDE SURFACE OF WELDED PIPED             Abstract of  the Disclosure An apparatus comprises a body mounting V-shaped two-arm levers.     Around the periphery of the body there are disposed cutting tool holders pivoted each to one arm of each of the levers. On the body there are mounted drives for turn-ing the levers, each of said drives being connected with the other arm of each of said levers. On the front ends and the rear ends of the cutting tool holders there are mounted rollers which are in contact with the inside sur-face of the pipe. The cutting tool holders hold cutting tools rigidly secured thereto.     Such an arrangement of the apparatus of the present invention makes it possible to increase the period between repairs several times, to appreciably reduce the power consumption and engine power required for the movement of the apparatus within pipes, and to substantially rule out the possibility of damaging the pipe walls and weld in the course of flash removal.

Abstract: HOWARD, R. E. 1-3-3 16.                     HIGH RESOLUTION TWO-LAYER RESISTS       Abstract This invention relates to the use of two-layer resist composite, with a more sensitive and thicker resist being the lower layer, in the production of devices requiring highly resolved features.  The improvement re-sides in selecting the sensitivity of the resist material of the upper layer and its thickness such as to allow, upon exposure of the composite to a dose of energy and removal of the exposed portions, production in the surface of the upper layer of apertures with a resolution of 5000 .ANG. (500 nanometers) or less, the thickness of the lower layer being selected to be sufficient to at least reduce adverse effects of said exposure upon the said resolution.

Abstract: IMPROVED AUTOMATIC INJECTION APPARATUS                      ABSTRACT OF THE DISCLOSURE         An improved automatic injection apparatus has a planar work surface with a hingedly attached retention plate which pivots from a raised position to a lowered position against the work surface in response to a member of an animal being forced against it to actuate a switch protruding through the work sur-face.  Actuation of the switch operates a drive mechanism which forces a hypodermic needle attached to a syringe through an opening in the work surface and through an aligned aperture in the retention plate into the animal member, operates the syringe to inject a fluid into the animal, and then retracts the syringe and needle to the initial position.  The retention plate is shaped to conform generally to the contours of the animal member and has oppositely facing restraining walls to accurately posi-tion the body member relative to the needle and to prevent lateral movement of the member during the injection process.  The aperture in the retention plate is elongated to insure passage of the needle therethrough regardless of the inclination of the needle relative to the work surface.

Abstract: 9D-HL-14768-Gerry ABSTRACT OF THE DISCLOSURE         A drive arrangement is disclosed for producing oscillation of a washing machine agitator and rotation of the basket for the spin cycle.  The arrangement consists of a DC motor having an oscillating mode and a unidirectional rotation mode, the motor driving a mechan-ically shifted transmission, including a planetary gear set driving the washing machine agitator during the oscillation mode of the motor.  A gear case is clutched to the washing machine basket during the spin cycle to produce direct drive of the basket during unidirectional rota-tion of the motor.  The transmission shifter arrangement  is operated by an incremental rotation of the drive motor which causes a cam follower-shifter member to be axially displaced from a neutral position to produce either a spin or agitate drive condition of the transmission.  A dynamic braking arrangement of the washing machine drive motor is provided by switching in a load across motor armature leads to cause braking of the agitator and basket spin whenever the drive motor is not energized.

Abstract: ABSTRACT OF THE DISCLOSURE An improved method and apparatus using edge shaping and traction rolls is disclosed for shaping and forming plastic foams as a foamable extrudate is extruded through an arcuate orifice of an extrusion die. Immediately adjacent and downstream of the die orifice are opposed sets of curved rolls, each having substantially the same center of curvature as the die orifice and being positioned, respectively, on opposite sides of the extrudate pass line. Moreover, two pairs of traction shaping rolls downstream of the curved rolls engage edge portions of the extrudate further to assist in shaping the same especially in connection with the shaping and forming of relatively wide bodies of plastic foam material. Several parameters of the traction rolls may be adjusted to selected values affecting the force and direction applied by such rolls to the extrudate. Parameters such as compression force, slippage, angle of attack, and/or surface area of the extrudate over which such forces may be applied, may be remotely adjusted.

Abstract: Abstract of the Disclosure:           On carrying out matching of two information compressed patterns, a weighted similarity measure calculator (64) calculates a weighted similarity measure by multiplying an intervector similarity measure between one each feature vector of the respective patterns by a weighting factor calculated by the use of a variable interval between each feature vector and a next previous one.  A recurrence formula is calculated by the use of such weighted similarity measures instead of the intervector similarity measures.  A predeter-mined vaiue .delta. may be used in reducing the number of signal bits used for the recurrence formula.  Preferably, a sum for the recurrence formula is restricted by two preselected values.  Most preferably, an additional similarity measure is used for the recurrence formula.     [Fig, 12]
