Title: Bistable zero insertion force connector
Inventor: HILLIS W DANIEL
IPC: H01R12/87
Filed: 1987-09-30
Granted: 1991-03-19
Abstract: ABSTRACT     A  bistable  zero  insertion  force  connector  assembly including  one  or  more  conductive  contact  members.   Each conductive contact member includes mating ends or contact arms having contact  surfaces  and  a  resilient  central  segment. Variable  engagement  means  cooperates  with  each  conductive contact member to displace the member from a first stable state to a second stable state and vice versa, with minimal force the member being maintained in the first or second stable states by means of stresses induced in the resilient central segment.  In the first stable state the contact surfaces of the mating ends or contact arms are disposed in mating proximity to the contact surfaces of the device to be electrically connected therewith with zero force/zero contact while in the second stable state there  is  secured  engagement  between  the  respective  contact surfaces.   Wiping  contact  between  the  respective  contact surfaces during transition between the first and second stable states enhances reliability of the electrical connection.

Abstract: METHOD FOR MANUFACTURING A MINERAL PANEL            Abstract of the Disclosure Method for the manufacture of structural mineral panels on a foraminous support wire by forming a dilute aqueous dispersion of mineral fiber and/or lightweight aggregate with some fiber and binder solids in water.  A small amount of cationic flocculant such as polyacrylamide is added sufficient to effect coating of the binder solids onto the mineral fiber materials and the slurry is passed to a first flooded section of the support wire to form an open, entangled, structural mass having water in interstitial spaces of the entangled mass.  Water is stripped from the mass and the mass dried substantially without collapse of the open structure, first by application of brief pulses of high vacuum followed by further vacuum and passing heated dry air through the open entangled structure.  This produces a very uniform homogeneous panel core with very evenly spaced and uniformly sized voids in the open cored structure.

Title: Computerized servo drive
Inventor: AROV ANATOLY
IPC: H02P27/02
Filed: 1988-03-22
Granted: 1991-03-26
Abstract: ABSTRACT OF THE DISCLOSURE         A simplified computerized servo drive for an AC motor is disclosed which comprises a central processing unit having a data input from a main computer, a data output connected to linear amplifiers and a feedback input.  The central processing unit produces various digital signals generally corresponding to sine waves. These signals are converted to an analogue signal and amplified by a linear amplifier with the resulting signal used to power an AC motor.  Speed and torque are adjusted in accordance with the main computer input and the feed. The signals produced can be varied in phase amplitude and frequency for varying the motor power.  Controlled acceleration and deceleration reduces peak current loads of the motor.  Feedback information to the central processing unit is supplied from prerecorded magnetic media associated with the drive of the motor and a suitable means for sensing the same.

Granted: 1998-12-15
Abstract: A color-changeable toy having a toy body to which a quasi-reversible thermochromic material is applied in a pattern.   This material  stably holds  either  of  two colored states in a range of ordinary room temperatures. However, the material reversibly changes to one of the states above this range and to the other below this range.   Thereby, by using commonly available heat and chilling sources such as ice, hot water or breath, one of the colors can be selected.  A breath blow pipe can be used in conjunction with the toy and have an external appearance associated with that of the toy, e.g., gun and soldier.

Granted: 1993-03-02
Abstract: PACKAGE HAVING FIBER-CONTAINING SHEATH AND APPARATUS AND METHOD FOR PACKAGING          Abstract of the Disclosure The package of the present invention comprises a sheath formed from a folded, relatively rigid strip having structure for receiving and releasably holding the ends of the fiber to be packaged.  In a preferred embodiment, the fiber is between the two folded over parts of the strip with the ends of the fiber anchored in place in a pair of slits.          The sheath is in a pouch formed by a pair of foil members on opposite sides of the sheath.  When ready for use, the package is opened by peeling the foil members apart, thereby exposing the sheath and permitting access to the fiber carried by the sheath.          An improved apparatus and method are provided to form the package.  In the first instance, the sheath is prepared by first folding a strip of relatively rigid material, such as siliconized polyester, then moving the folded strip along a path of travel and feeding the fiber into the region between the parts of the strip as the strip moves.  At a certain location along the path of the strip, the fiber is forced into each slit of the strip and the fiber becomes releasably attached to the strip.  At another location, the strip is cut; thus, in this way, a plurality of sheaths with fiber lengths between the sides of the sheaths are formed and are immediately moved to a location where the foil members are applied to the opposite sides of the sheaths.

Granted: 1992-10-27
Abstract: WATER RESISTANT COMMUNICATIONS CABLE            Abstract A communications cable comprising a core of at least one transmission media and a plastic jacket includes provisions for preventing the movement of water within the cable. A water blocking yarn or strip is interposed between the core and the jacket and extends either linearly along the cable or is wrapped helically about a portion of the sheath system. In any plane along the cable which is traverse to the longitudinal axis of the cable, the yarn or the strip extends about an insubstantial portion of an inner periphery of the cable. As a result, any desired bond between the jacket and an underlying element of the cable sheath system is discontinuous for only an insignificant portion of the peripheral surface of contact. The yarn may be one which has been treated with a superabsorbent material whereas the strip may comprise a substrate strip which has been impregnated with a superabsorbent material which upon contact with water swells and inhibits the movement of water within the cable.
