Abstract: 412-1707 A high frequency electrical connector system for electrically interconnecting corresponding first and second circuit elements includes a first planar array of pad-type contact terminals disposed on a substrate and connected to a first circuit on the substrate, together with first guide structure adjacent the first array of contact terminals. A cooperating second array of pad-type contact terminals is mounted on a rigid nonconductive contact support structure that includes a resilient contact terminal array mounting, camming structure and second guide structure for cooperation with the first guide structure. The contact support structure is resiliently coupled to a carrier structure that includes cooperating camming structure. Flexible multi-conductor interconnection structure has one end electrically connected to a cooperating electrical circuit secured to the carrier structure and its other end connected to corresponding terminals of the second array. Fastener structure is adapted to secure the carrier structure and the substrate together with guide structures in engagement. As the fastener structure moves the carrier structure towards the substrate, the camming structures interact and move the contact support structure laterelly (parallel to the plane of the contact arrays) in transverse wiping action, as directionally guided by the engaged first and second guide structures, to remove debris or other foreign matter (such as corrosive films) which may adversely affect electrical circuit performance.

Abstract: PATENT - 9D-MA-16920-Welle et al POWER CONTROL FOR COOKING APPLIANCE                      WITH MULTIPLE HEATING UNITS                  ABSTRACT         An improved electric cooking appliance with a plurality of heating units arranged in two groups, a first group adapted for energization by a first AC power signal and a second group adapted for energization by a second AC power signal, 180° out of phase relative to the first power signal.  The heating units of the first and second groups are each connected to a common neutral power line.  The output power of each of the heating units is controlled in accordance with the user selected power setting for each unit by selectively applying current pulses to each heating unit at a pulse repetition rate corresponding to the user selected power setting for that heating unit, with the application of current pulses to each heating unit being further controlled to minimize the concurrent application of current pulses to those heating units energized by the same one of the first and second power signals and to maximize the concurrent application of current pulses to those heating units energized by different ones of the first and second power signals, thereby minimizing the peak current pulses in the common neutral line.

Title: Child resistant closure energy planes
Inventor: WILSON WOODROW S

Granted: 1991-09-24
Abstract: ABSTRACT         A child resistant dispensing closure of the type having a cap and a spout mounted thereon for rotation about a substantially horizontal axis.  The upper surface of the cap is provided with a pattern of ribs.  The upper surface of the spout is provided with a plurality of ribs, each of which has a distinct energy plane.  All but one of the energy planes fails to allow sufficient purchase on their respective ribs and fails to produce the proper force vector required in order to initiate rotation of the spout when a manual force is applied to the latter energy planes.  Only one of the energy planes is adapted so as to allow sufficient purchase and to produce the proper force vector required in order to initiate rotation of the spout when a manual force is applied to said one plane. The plurality of ribs provided on the spout, in conjunction with the pattern of ribs provided on the cap, blend together and serve to distract and confuse a child or other individual of reduced mental capacity, thereby effectively reducing to negligible the probability that the child or other individual would inadvertently discover the sole energy plane capable of realizing rotation of the spout while exploring the dispensing closure with the fingers, fingernails, teeth or other objects.  The spout may be mounted on the cap in such a manner as to require relatively little rotational torque for rotation, thereby making the dispensing closure convenient and easy to utilize by adults, even those not possessing normal physical strengths.

Granted: 1991-10-29
Abstract: ABSTRACT            NITROGEN STIMULATION OF A POTASSIUM HYDROXIDE WELLBORE TREATMENT     Clays in water sensitive subterranean formations are stabilized by injecting a sufficient amount of an inert gas, preferably nitro-yen,   into the formation to substantially fluidize the clays (in-cluding migratible fine particles),  thereafter  injecting  into the formation an aqueous solution of soft water and potassium chloride to effect a cationic exchange between the potassium and the sodium within the clays and then injecting into the formation an aqueous solution  of  soft  water  and  potassium  hydroxide.   The  potassium hydroxide  renders  the clays  relatively  insensitive  to  an aqueous solution having an ionic makeup distinct from connate waters within the formation, thus, this process protects against formation damage by a "fresher" water,  The well can be an injection well or a pro-duction well.

Granted: 1993-06-29
Abstract: APPARATUS AND METHOD FOR MONITORING LIQUID LEVELS            Abstract of the Disclosure An apparatus to indicate a low level of liquid in a vessel, such as an automobile crankcase. A light-emitting diode and a phototransistor are coupled at the crankcase so that the light received by the phototransistor varies with rising or falling oil levels. The diode has a given maximum current rating. A unique pulse generating circuit applies a short duration, high-current pulse to the light-emitting diode to produce a correspondingly short but intense burst of radiant energy that is received by the phototransistor. The advantage of the present arrangement is that the sensitivity of response is superior to that of a phototransistor employed with a light-emitting diode driven by low-level voltages giving rise to currents equal to or less than its steady-state rating. False readings are eliminated when the vehicle is on an incline, or when the ignition switch is improperly operated. Reli-able functioning is had, even at high operating tempera-tures.
