Abstract: ABSTRACT OF THE INVENTION   A flail chain connector is provided which may be applied to an existing wood debarking apparatus or machinery for cutting vegetation. The connector is provided with integral fasteners for removable attachment of a length of flail chain to a powered rotary shaft. The connector may be removably engaged with the flail chain by moving a link in the flail chain and one integral fastener to a first relative position and thereafter moving the link and fastener into a second relative position. The connector may be disengaged from the flail chain by relative movement of the link and fastener from the second position, to the first position, and finally to the disengaged position. The connector may be removably engaged to the shaft by a second fastener through relative movements to a first and second relative positions.

Title: Eccentric c-fold mailer with return envelope
Inventor: SAUERWINE DEAN N
IPC: B42D15/08
Filed: 1993-08-16
Abstract: An intermediate for a mailer type business form, and the mailer type business form constructed from the intermediate, provide a construction in which a minimum amount of paper can be utilized to provide the maximum amount of information, yet allow easy construction of a return envelope from the original components of the mailer. The mailer constructed according to the invention is also thin. The intermediate has three panels which are eccentrically C-folded with the outgoing address visible through a cut-out (with transparent patch) in an outer panel.      The return envelope is constructed by the recipient by removing release liner strips from pressure sensitive adhesive strips inside the mailer, forming the sides of the return envelope. The recipient of the return envelope can easily tell who the return envelope is from since the outgoing address is provided on the inner portion of the flap of the return envelope.

Title: Thermal Analysis Instrument
Inventor: NAKAMURA NOBUTAKA
IPC: G01N25/48
Filed: 1994-03-25
Abstract: The temperature of a heat reservoir is varied according to a linear function which is AC modulated. At the same time, a temperature difference between two points located in a heat flow path from the heat reservoir to an unknown sample is measured. The temperature difference between two points located in a heat flow path from the heat reservoir to a reference sample is also measured. These two pairs of points are arranged symmetrically. The resulting DSC (differential scanning calorimeter) signals are demodulated, and each signal is divided into an AC component signal and a low-frequency component signal. Using these signals, the DSC signal is separated into a heat capacity component and a latent heat component.

Abstract: An improved long-term predictor (LTP) for use in analysis-by-synthesis coding systems, such as CELP is disclosed. The invention provides control of theperiodicity of speech signals generated by the LTP. This control facilitates a reduction in perceptible noise/buzziness in reconstructed speech. An embodiment of the invention includes a conventional LTP in combination with a two-tap finite impulse response filter.

Abstract: A method and apparatus for forming a slide-fastener coupling element from a metal wire having a substantially Y-shaped cross section wherein a blank piece is cut or sliced off from the metal wire by a co-action between a cutoff die and a cutoff punch, and substantially at the same time, the metal wire is chamfered along a next cutting line by a chamfering edge so as to form a substantially V-shaped groove extending in and along the peripheral surface of a head portion of the metal wire and the outside surface of each of two opposed leg portion of the metal wire.  The next slicing operation produces a blank piece which is already chamfered at its upper and lower peripheral edges extending along the peripheral surface of the head portion and the outside surfaces of respective leg portions of the blank piece.  A finished coupling element shaped from the thus chamfered blank piece is smooth to touch and ensures smooth sliding move-ment of a slider which will guarantee smooth opening and closing operation of a slide fastener.

Title: System for converting mechanical energy produced by the engine of a conventional motor vehicle into an electrical current suitable for powering household products
Inventor: TRUNG SAC H
IPC: H02M5/458

Abstract: SYSTEM FOR CONVERTING MECHANICAL ENERGY PRODUCED BY THE ENGINE          OF A CONVENTIONAL MOTOR VEHICLE INTO AN ELECTRICAL CURRENT          SUITABLE FOR POWERING HOUSEHOLDS PRODUCTS          ABSTRACT OF THE DISCLOSURE: A system for converting a portion of the mechanical energy produced by the engine of a conventional motor vehicle into an electrical current which is suitable for powering conventional household appliances. The system thus allows a conventional motor vehicle to be temporarily used as a backup source of electrical energy. The system uses a modified alternator having a non-rectified output. The multi-phased current produced by the modified alternator is first sent to a multi-phase step-up transformer which increases its voltage value. The current emanating from the transformer is then rectified by a bridge rectifier and stabilized by a voltage regulator. The current is then used to charge a capacitor. The electric charge of the capacitor is converted either electronically or mechanically into an alternative current having a voltage value and a frequency value compatible with conventional household appliances.

A curve (FE) is obtained by similarity transforming at a reduction ratio of 1/2 a portion from a starting point (A) of the envelope (e) to a terminating point (E) thereof corresponding to two times the working depth in the direction of the depth from an apex of a moving locus (~ o) when deviation is 0, using the terminating point as an original point, and this curve is made to be each of main portions of convex tooth profiles at tooth faces of the both gears (2, 3). Further, a composite curve (MFE) including a straight line (MF) having a limited pressure angle (.alpha.M) associated with a deflection value of the opening inserted in the vicinity of a datum point (M) of tooth profile and a transient curve smoothly connecting the straight line to the main portion of the convex tooth profile is made to he each of tooth profiles at the tooth faces of the both gears.
