Abstract: A B S T R A C T              Underground bituminous sand deposits are heated by mechanical wave energy to fluidize the bituminous sand thereby to facilitate extraction thereof.  For uniform, circular, symmetrical dispersion of mechanical wave energy of high-power and low-frequency, a mechanical wave energy radiator is provided comprising a cylindrical elastic tube of springy steel or the like preferably dimpled or corrugated and closed at one end and containing a liquid medium.  Mechanical wave energy is applied to the liquid medium by a reciprocating source or the like connected to the radiator by a rigid walled tubular pipe or the like.  The axial length of the radiator tube should be an odd multiple of one-quarter wavelength of the mechanical wave energy transmitted.  Cavitation within the liquid is avoided by biasing the system with a steady state pressure at least as great as the maximum negative pressure swing of the mechanical waves in the liquid.  Trans-formers are disclosed for accommodating changes in pipe dia-meter and changes in liquid medium throughout the system.

Abstract: AN ELECTROSTATICALLY BONDED SEMICONDUCTOR-ON-INSULATOR MOS DEVICE, AND A METHOD OF MAKING                     THE SAME                  ABSTRACT OF THE DISCLOSURE        An electrostatically bonded semiconductor-on-insulator and particularly semiconductor-on-sapphire MOS devices are made of bulk materials.  A semiconductor body of a bulk material of less than about 75 microns in thick-ness is electrostatically bonded to an insulator substrate of a bulk material.  A dielectric layer of between 500 and 2,000 Angstroms in thickness is then formed on the semiconductor body to make a MOS semiconductor device and preferably a MOS field-effect transistor.         The semiconductor-on-insulator MOS device is pre-ferably made by first forming a major surface of the dielec-tric substrate and a major surface of the semiconductor body in planar configurations, applying a metal layer to the opposed major surface of the insulator substrate, and placing the planar surfaces of the body and substrate in intimate contact.  The assembly is then heated to at least 300°C. and preferably at least 700°C. while avoiding oxidation of the contacted surfaces, and thereafter applying an electrical potential of at least 700 volts between said metal layer and the semiconductor body to electrostatically bond the insula-tor substrate to the semiconductor body.  The electrostatical-ly bonded assembly is then cooled at a rate less than about 10°C. per minute to a temperature of about 300°C. and pre-ferably to room temperature.  Then, a dielectric layer and metal layer are applied on the semiconductor body to complete the semiconductor-on-substrate MOS device.

Abstract: ABSTRACT OF THE DISCLOSURE        An improved process for preparing adhesive repellent coatings is provided.  The process includes the steps of:  applying to the surfaces which are to be rendered adhesive repellent, an aqueous emulsion contain-ing (1) diorganopolysiloxanes having Si-bonded vinyl groups in their terminal units, (2) organopolysiloxanes having at least 3 Si-bonded hydrogen atoms per molecule [preferably wherein the organopolysiloxanes (2) are present in an amount of 1 gram equivalent of Si-bonded hydrogen for each 0.3 to 0.8 gram molecule of Si-bonded vinyl groups in the diorganopolysiloxanes (1)], and (3) catalysts (known per se) which pro-mote the addition of Si-bonded hydrogen to vinyl groups, present in a catalytic amount preferably, where the catalyst is a platinum-containing compound of from 0.001 to 0.02 per cent by weight based on the weight of the diorganopolysiloxanes (1), and thereafter cross-linking the polysiloxanes (1).  The improvement involves the step of mixing the cata-lyst (3) with the diorganopolysiloxanes (1) prior to the addition of water, preferably where the catalyst (3) is mixed with at least one-half of the total diorganopolysiloxanes (1) in the absence of a dispersing agent and water to form a homogeneous mixture and thereafter the resultant mixture is mixed with a dispersing agent and water.  By this improvement, the solutions are more stable.  Since the aqueous solurions can be preserved over a long period of time and still produce coatings as good as those obtained from freshly prepared emulsion, optimum utilization of continu-ously operated coating devices is achieved without migration of the repellent coatings.  The coatings so prepared may be used as separating, cover and lining papers, boards, films and cloths.

Abstract: ABSTRACT OF THE DISCLOSURE A continuous clear surfaced web adapted to be fed from a supply roll thereof for a converting operation thereon is preprinted with n succession of identical repeat patterns extend-ing over the entire width of the web. Each pattern consists of areas which contain printed matter and at least one longitudinable discontinuous area or segment which, except for the presence of a printed register mark therein, is clear and unprinted. A photo sensitive scanner is directed at the register mark track of the feeding web for detecting the register marks and controlling in accordance therewith the timing of an associated machine operation, such as web splicing, so as to be performed in register with the web pattern. The operation of the scanner is controlled by a digital reset counter of pulses fed from a pulse generator driven by the seb feeding mechanism. The counter is reset to zero upon the detection of each register mark. It is initially preset to a number during the count of which the scanner is deactivated and after the count of which the scanner is activated. The number preset in the counter corresponds to the length of the register mark track starting from one register mark and continuing up to the segment of clear track containing the next register mark. The counter thus gates the operation of the scanner so as to detect only register marks and not to misread other printed matter lying in the scanned track as a register mark.

Abstract: ABSTRACT OF THE DISCLOSURE It is known to measure the frequency of microwave signals by heter-odyne conversion or by transfer oscillator techniques.  Heterodyne conversion frequency counters are limited in their ability to measure the frequency of pulsed microwave signals.  On the other hand, while transfer oscillator fre-quency counters can measure the frequency of pulsed microwave signals they have limitations in measuring signals with large frequency modulation compo-nents.  The present invention utilizes analog microwave frequency dividing devices to virtually instantaneously convert the signal to be measured in oc-tave steps into the frequency regimes associated with digital frequency count-ers.  The apparatus disclosed comprises an antenna or other device for re-ceiving a microwave frequency signal and feeding it to an analog frequency divider system having n stages, where n is an integer, each stage dividing frequencies applied to it by a factor of 2.  The output of the divider sys-tem feeds a digital counter which, in turn, feeds a digital display device which displays a number equal to 2n times the output of the digital counter and hence equal to the frequency of the received microwave signal.
