Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is a torque transmitting and blocking device which includes a cylindrical drum, a pair of arcuate shoes positioned within the drum, and a spanner bar extending between the shoes to one side of the axis of the drum.  On the other side of the drum axis the shoes are displaceable toward each other, and may conveniently be lightly biased apart.  The shoes have surfaces, which may include holes, lateral or transverse pro-jections, or the ends of the shoes, through which rotative forces may be transmitted from sources external of the drum and through which the shoes may retransmit such forces.  Application of a rotational force through such a surface into a shoe in a direction tending to displace the shoes toward each other results in rotation of the shoes and bar within the drum, and consequent transmission of torque, if desired, out of the drum through another shoe surface. Application of a rotational force into a shoe in a direction tending to displace the shoes away from each other throws the shoes into a jamming relationship with the wall of the drum and prevents transmission of torque past or through the device.  Applications of the device in apparatuses for winches, stepping clutches, and automatic load holders are disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE           Hydrophilic, crosslinked modified organopolysiloxanes are obtained from the polymerization of hydroxyalkylmethacrylate and/or hydroxyalkylacrylate in the presence of an organopolysiloxane which is soluble in the polymerizable monomer and has a molecular weight of at least 1,000, in which the organic groups of the organopolysiloxane are selected from the group consisting of hydrocarbon radicals, halogenated hydrocarbon radicals and mixtures thereof, said organopolysiloxane is crosslinked by condensation or by the addition of Si-bonded hydrogen to Si-bonded alkenyl groups, and containing at least 40 mol percent of monoorganosiloxane units.  The amount and type of condensation catalyst and/or catalytic system, including the inhibitor for the polymerization of the hydroxyalkylmethacrylate and or hydroxyalkylacrylate in the poly-merization process, is selected so that the crosslinking of the organo-polysiloxane, which is substantially uniformly distributed in the hydroxy-alkylmethacrylate and/or hydroxyalkylacylate, is initiated and preferably completed before the polymerization of the hydroxyalkylmethacrylate and/ or hydroxyalkylacrylate is complet ed.  The modified organopolysiloxanes are more rigid than prior organopolysiloxanes.  Thus, contact lenses made therefrom or containing such modified organopolysiloxanes enhance the correction of visual deficiencies which are attributable to a de-formation of the cornea, for example, astigmatism.

Abstract: ELECTRIC FOREHEARTH ABSTRACT OF THE DISCLOSURE         Disclosed is a method and apparatus for preventing the formation of blisters in an electrically-heated fore-hearth that utilizes submerged electrodes connected to either a single or plural phase alternating current source.  The electrodes are arranged so that Joule effect heating is effected by passing alternating current through the molten glass with the center tap of the secondary of the power trans-former being connected to the positive side of a Direct Current source through a filter, while the negative side of the DC source is connected to a counter electrode, immersed in the glass at a point upstream of the forehearth.         With this physical arrangement, the formation of blisters due to free electrons migrating to and collecting on some of the electrodes that are at different potentials than the others is prevented.  This is accomplished by the fact that all of the forehearth electrodes are maintained at the same potential and the counter electrode is at a different potential so that these free electrons will collect at the single counter electrode and create bubbles or blisters at a position well in advance of the forehearth.  With this system, the blisters will disappear before reaching the fore-hearth.  The forehearth electrodes are disclosed as being formed of stainless steel with molybdenum tips and the elect-rode support being electrically isolated from the forehearth structure.

Abstract: ABSTRACT OF THE DISCLOSURE         Compositions of an a method for pre-paring polymeric formulations that gradually, con-tinuously and uniformly release various compounds over a long period of time in ionic form that are well recognized as essential to the growth of agri-cultural commodities. The compounds, such as inor-ganic salts of varying water solubilities, are mono-lithically incorporated in a thermoplastic polymeric matrix usually of two thermoplastic polymers, for example, a copolymer of poly(ethylene-vinyl acetate) or a copolymer of ethylene and propylene. Release is generally conditioned upon the presence of moisture and is proportional to the moisture content of soil treated with the subject invention. Release rate is tailored to a given desirable condition by regulation of the free volume and/or polarity within the polymer matrix and through dispenser geometry. Free volume is maintained at the level conducive to agent release such as through the use of free volume modifying secondary thermoplastic additives such as low density polyethylene; and porosity is controlled through the use of porosity enhancing agents appropriately termed porosigens. Said porosigens can be the low or moderate soluble salts such as the carbonates, bicarbonates, sulfates, phosphates, nitrates, etc.; of the alkali metals, the alkaline earths, or ammonium. Upon exposure to moisture, water ingress into the dispens-ing pellet removes said porosigen through dissolution.     processes thus creating a porous network permitting water contact with the incorporated nutrient mole-cules and their gradual egress in said water over a period of time such as for about a couple months to four years, or longer.

Abstract: BE IT KNOWN THAT Helmut Erb of  Emmastrasse 3, 6050 Offenbach/Main and Werner Leese of Spechtstrasse 9, 6078 (Gravenbruch) Neu Isenburg, Germany, both of German nationality, having made an invention entitled:           -- A COMBUSTION AUTOMATIC CONTROL SYSTEM --the following disclosure contains a correct and full descrip-tion of the invention and the best mode known to the inventors of taking advantage of the same.                          ABSTRACT    The invention is with respect to a fail-safe system for stopping damage to water boilers, whose thermostats are not in working order.    In an automatic combustion control system of the sort having an elastic thermostat bellows element placed within an outer shell within the water space of a boiler and joined by a chain or the like with the air door for controlling the air inlet rate at some point in the connec-tion between the thermostat element and the door, there is a temperature-sensitive part, for example in the form of a plug of fusible metal or collapsing material, or in the form of a soldered join using a special fusible solder.  In one form of the invention, this temperature-sen-sitive part may take the form of a ring of temperature-sensitive material placed at one end of a spring which is forced together on the temperature increasing. On damage to the thermostat element, the one end of the spring will no longer be supported so that the spring will no longer take effect and so let the air door be moved down under its own weight into the shut position.    In a further form of the invention, a body of tem-perature-sensitive material is placed between a rod, acting on one end of the thermostat element and a  turning head which is used for making adjustment in the desired tem-perature.    In a further form of the invention, the temperature-sensitive part takes the form of a plug of temperature-sensitive material between the end of a gripping screw in a jointpiece and a turning rod acted upon by said screw.    In a still further form of the invention, the temperature-sensitive part takes the form of a bimetallic wing, which is unhooked from a jointpiece on being heated to a limit tempe-rature. As part of a still further form of the invention, a guide roller for a chain joining the thermostat with the air door is fixed to the side of the boiler by way of fusible solder, this taking the form of the temperature-sensitive part.

Abstract: PHN. 9816                       22 ABSTRACT:       The invention describes a semiconductor switch-ing device for transferring a signal charge Qs from a first capacitor Cs to a second capacitor Cd.  In order to achieve a transfer rate high enough to perform the transfer within a well determined period T, means are provided for periodi-cally transferring back a fixed quantity of transferred charge into Cs.  The frequency and the amount of charge of said back-transfer are chosen such that within the period T an equilibrium is reached in which charge transferred from Cs per unit of time is substantially equal to the charge transferred from Cs in the same unit of time.  The invention may be used, in  particular, in a camera wherein within the line flyback time an optionally generated signal has to be transferred from a sensor into read-out means.
