Abstract: ABSTRACT OF THE DISCLOSURE         This invention relates generally to a transfer mechanism for microorganisms and more specifically, to a device for duplicating a growth pattern of microorganisms.  The apparatus comprises a body and a transfer material on one surface of the body.  The transfer material is brought into contact with a primary medium having a growth of microorganisms on the surface thereof, and transfers that growth to at least one secondary medium.  The apparatus is particularly suitable for use with a hydrophobic grid membrane filter.  This apparatus replaces slow and cumbersome methods for transferring microorganisms from a primary medium to a secondary medium and is an automated and efficient apparatus to effect such transfer.  This device makes it now possible to transfer  or duplicate the colonies of micro-organisms growin on a hydrophobic grid membrane filter to fresh or different culture.

Abstract: ABSTRACT    A process for the production of construction material comprising the steps of:    1.   heating the soil to a temperature sufficient to substantially destroy the property of the soil to swell with changing levels of moisture without causing any of the soil constituents to melt, which temperature will normally lie between 500 and 750°C depending upon the soil type, 2.   adding to the soil, either before or after the heating step, iron oxide in a finely divided form, and 3.   introducing into, or creating within, the mixture a solution of sodium silicate, such as by adding an aqueous solution of sodium silicate to the mixture or by adding to the mixture a strong solution of sodium hydroxide and a silica source. The construction material formed by the process, and articles formed therefrom, form part of the invention.  The construction material could be used for the production of articles such as bricks or tiles or for the formation of massive structures such as building foundations or road bases.

Abstract: TOY LAWN MOWER ABSTRACT OF THE DISCLOSURE A toy lawn mower shaped like a conventional wheeled lawn mower and including an enclosure in the shape of a grass catcher which simulates a real grass catcher.  The enclosure, which has at least one transparent side, includes means located near its bottom to agitate grass-like particles to simulate the appearance of grass blown from the mower housing into a grass catcher.  The agitating means is opera-tively connected to a wheel axle of the toy to agitate the particles in response to movement of the toy.  The toy lawn mower also has means to vibrate the lawn mower so that the grass simulating particles will collect at the bottom of the enclosure for continuous reagitation.  A sounding means connected to a wheel axle of the toy emits a sound similar to that of a real lawn mower when the lawn mower is pushed.

Abstract: A DIGITAL SIGNAL SUBSCRIBER LOOP AND INTERFACE CIRCUIT Abstract of the Disclosure A TDM PCM telephone system and a telephone user terminal are interconnected by a digital subscriber loop circuit which provides at least a single channel communication path for digital signals of data or encoded voice origin.  The digital subscriber loop circuit includes transmit and receive paths and a line interface circuit.  The line interface circuit converts a selected channel of binary signals appearing at a subscriber line port of the telephone system into a corresponding bipolar return to zero (BPRZ) signals for transmission on the receive signal path.  The line interface circuit also converts BPRZ signals from the transmit signal path to corresponding binary signals.  These binary signals are accumulated and stored.  At a time coincident with the selected channel occurrence, the line interface circuit transmits the stored signals to the subscriber line port for acceptance by the telephone system.  In one arrangement, the digital subscriber loop is interfaced at opposite ends by a universal line interface circuit (ULIC) which provides for compatible use with two TDM signal formats and with any one of a plurality of commercially available single channel codecs in the associated telephone user terminal.                             - i -

Abstract: ABSTRACT OF THE DISCLOSURE         A method is disclosed for the reactive plating of substrates to produce transparent conducting films and photoactive coatings.  Reactive gases at low pressures are introduced into a vacuum chamber having a partial vacuum therein.  A substrate located in the vacuum chamber is subjected to a glow discharge in the partial vacuum.  A coating material, such as zinc or silicon is vaporized in the vacuum chamber to react with the gases, with the resulting compound being deposited on the substrate by the effect of the glow discharge.  The power in the glow discharge and the partial pressures of the vaporized coating material and gases introduced into the vacuum chamber can all be controlled separately to vary the stoichiometric ratios and the properties of the coatings.          The electrode geometry is arranged and the operation maintained such that the power density distribution in the discharge is fixed and controlled.

Abstract: ABSTRACT          The invention is referring to a storage carrier to be used in a fermentation interruptur  for the production of rolls or similar products with a pattern. The first stage of such rolls are dough crudes in form of dough cuts whose ends are rolled or wrapped up towards the centre, where they are form-ing a contact seam. It is necessary that during the later baking process this contact seam is ripping up or cracking and there Is resulting the so called pattern (Ausbund). The possibility to produce such rolls from the dough crudes is depending on different effects  during the procedure in the fermentation interrupturs. For ensuring on the one side a sufficient raising effect and to privent on the other side the access of to much air humidity, it is proposed to provide a storage carrier with a supporting framework having deepenings for taking up the dough crudes as well as a textile cover and a foam plastic layer between the supporting framework and the textile cover. Preferably the foam plastic layer and the textile cover are formed of one piece..

Abstract: Abstract of the Disclosure A system and method are disclosed for con-trolling blood flow or flow of biologic fluid in an artificial organ or extracorporeal blood circuit. Selected parameters relating to blood flow are sensed and used to automatically optimize blood flow while assuring proper and safe operation.  Utilized in con-junction with a reciprocating dialyzer apparatus, the system controls blood flow into and out of the dialyzer apparatus by controlling pressure on a slurry around the dialyzer membrane package.  Slurry pressure is controlled by an actuator, such as a bellows pump, the pumping action of which is controlled by an electric motor, which motor, in turn, is electrically controlled by a control unit which receives sensed indicators of blood flow, pressure and/or motor current.  Blood contamination is also monitored for assuring safe operation of the dialyzer apparatus.

Abstract: CONVERSION OF HEAVY PETROLEUM OILS       Abstract Heavy petroleum oils, such as vacuum resids and heavy fractions of tar sands and shale oil, are partially converted to more volatile hydrocarbons by mixing with light aromatic hydrocarbons and treatment of the mixture with a transalkylation catalyst, for example a Friedel-Crafts catalyst such as aluminum chloride.  It is believed that the conversion is essentially a transalkylation, i.e. the resid undergoes dealkylation with concurrent alkylation of the light aromatic hydrocarbon.

Abstract: ABSTRACT         A substantially solvent-free adhesive composition consists essentially of an elastomer and tackifier, 3 metal oxide and, optionally, a plasticizer.  The elastomer is selected from the group consisting of polar elastomers and unsaturated elastomers which have at least 5 mole percent unsaturation, said elastomer being a non-crystalline elastomer or an elastomer which has a slow rate of crystal-lization such that after a time period of at least 100 hours has elapsed following subjecting the elastomer to a temperature of 70°C for 30 minutes, the elastomer has a room temperature Shore A hardness of less than 60.  The adhesive compositions can be formed into a shaped article, such as of a tape,  film,  sheet or tubular sleeve,  if desired.  The compositions have high adhesive strength for bonding together a variety of substrates.  The adhesive is particularly  useful  with  a  dimensionally  recoverable article, such as a shrinkable sleeve, to bond the recovered sleeve to a substrate such as an electric cable.
