Abstract: Abstract Implantation of a particle flux, for example a laser produced particle flux, upon a substrate is enhanced by premelting the substrate surface with a beam of radiation from a pulsed high energy source such as a laser source.  The premelting is provided prior to the arrival of the particle flux in order that the particle flux impinge upon an area of the substrate which is melted. (Figure 1)

Abstract: ABSTRACT         The present invention relates to a method for utilizing and storing environmental energy, using a storage-medium operating by chemical reactions or sorptions, whereby in the said storage-medium, more particularly silica-gel or zeolite, exergy is accumulated at high density, during energy-charging, by a gaseous inert carrier-medium for the exergy in the storage medium, the stored exergy being removed, as required, during charging, also by means of a gaseous inert carrier-medium, from the storage, for conversion into heat or cold at a desired level.  The method according to the invention is carried out in such a manner that:    (a)  during energy-charging, the exergy is accumulated from minor disequilibrium conditions in the environment, and/or (b)  during energy-discharging, the residual exergy contained in the emerging gaseous inert carrier-medium is used for energy-charging an additional storage-medium in which little or no exergy has accumulated.

Abstract: Vibration Dampening Apparatus for Motor Actuated Eccentric Forces Abstract of the Disclosure This invention pertains to induced vibration and the dampening of these vibrations in the motor means.  Vibration induced by rotating a shaft having eccentric weights thereon has been used to produce all kinds of shaking apparatus including large car shakers in which the induced force may be as much as eight thousand two hundred pounds, These vibrations can be as much as five thousand six hundred vibrations per minute and can be used for huge bins and hoppers in which the capacity may be as much as one hundred fifty thousand pounds.  Vibrators using air, electric or hydraulic motors can be tuned or adjusted to provide the desired results.  Most of these vibrators using a tuned motor may be temporarily or permanently attached.  Motor driven vib-rators, as far as is known, transmits the vibrational force into the shaft of the motor.  Said motors, which are usually standard off-the-shelf units,have their rotor bearings designed for rotary motion rather than combined with a vibratory force.  This vibratory force reduces the life expectancy of these motor bear-ings.  A rubber dampener device is used between the motor output shaft and the eccentric shaft which eliminates all vibration transfer to the shaft and another vibration shock absorbing device is also provided to prevent transmission of vibration to the motor.

Abstract: Abstract of the Disclosure The invention relates to an electric hot plate with an overheating safety switch.  The switch rests on the lower heated side of the hot plate body and is positioned in the heated annular part of the plate.  The safety switch comprises a bimetallic strip and a snap switch actuatable by the bi-metallic strip and mounted in a chamber inside an extended housing.  The housing projects through a cover covering the lower side of the hot plate body and the safety switch is applied onto the lower side of the hot plate by this cover which has connections for the switch and at least one lead-through passage for at least one connection line of the hot plate which is not connected by the switch.  In accordance with the invention, the bimetallic strip is positioned out-side the housing of the safety switch in an open chamber formed between housing projections which rest with their ends against the lower side of the hot plate body, and extends lengthwise to the housing longitudinal extension and acts on a transmission member projecting through a housing open-ing and transmitting deflection of the bimetallic strip to the snap switch.

Abstract: ABSTRACT This application discloses a double tier ski rack comprised of two frames, each of which may be connected to an automobile by essentially conventional means and each of which may incorporate pivotal hold-down arms, which are likewise essentially conventional.  The hold-down arms may be locked in place by the usual locking mechanism whereby a first series of skis may be clampingly supported between support surfaces of the spaced frames and the hold-down arms.  The rack of this application is characterized by the presence of a second set of hold-down arms pivotal relative to the first set of hold-down arms, so that a second series of skis may be clamped between the arms of the first and the second sets, providing two layers or tiers of skis. The second arms may have a separate lock mechanism interposed between the second arms and the frame or the first arms.  For purposes of simplicity and cost saving, the second arms may carry at their distal ends a link adapted to be clamped between the frame and the first hold-down arms, so as to be locked in place when the first arms are locked to the frame. With this arrangement a single locking mechanism effectively locks both the first and second hold-down arms against movement from the carrying to the loading position.

If  sound is sensed in the specified environment within the  predetermined  time  interval,  a  signal  is  generated  to energize  or  maintain  energization of one  or  more  electrical devices,   Contrarywise,  if  no  sound is  detected  within  the predetermined time interval, there is a resultant de-energization of  the  electrically  operable  equipment.   A  control  may  be provided  to  adjust  the predetermined  time  delay  period.   A control may also be provided for adjusting the sensitivity of the device.

Abstract: METHOD AND APPARATUS FOR ENCODING AN NRZI DIGITAL          SIGNAL WITH LOW DC COMPONENT     ABSTRACT OF THE DISCLOSURE           Successive n-bit information words are converted into successive m-bit NRZI code words by assigning to each n-bit information word at least one m-bit code word having a respective NRZI disparity.  The digital sum variation of the preceding m bit NRZI code words is determined and the polarity of the conclusion of the immediately preceding m-bit NRZI code word is detected.  An assigned m-bit code word is selected to represent the next n-bit information word as a function of the NRZI disparity of that code word, the determined digital sum variation and the detected polarity.  The selected m-bit code word then is modulated in NRZI format such that the modulated code word has the same initial polarity as the detected polarity.  The m-bit code word is selected such that its NRZI disparity, when combined with the determined digital sum variation, tends to prevent the digital sum variation from increasing.
