Abstract: Snow stop has a base, a snow-hindering member, and a convolute hook. The convolute hook includes a forward section, a first opening section, and a further opening section; the convolute hook can be present at a distal end of a base of the snow stop, and it also can include a distal base bend section, and an extending section. The snow stop can have its base and convolute hook made to include sheet metal, for an example, copper. In general, the convolute hook can act as a spring. The hook minimizes or eliminates crushing of the same, and the snow stop can be retro-fit in slate, shake and shingle roofs efficiently.

Abstract: An anti-theft device to be applied to a shoe and provided with a sensor element (52) of an alarm system comprises two clamp plates (11, 12) which can be tightened against each other by a screw mechanism to be attached to the shoe straddling the edge of the upper leather thereof which defines the insert opening for the foot, and a device for preventing operation of the screw mechanism for displacement of the clamp plates from the tightened position, which can be actuated by means of a special tool only.

Abstract: An impingement distributor for a shell and tube heat exchanger and a method of recovering waste heat from a hot gas which minimizes adverse heat flux at the outermost banks of tubes for enhanced operational reliability. The impingement distributor has a cylindrical distribution plate having evenly arranged rows of longitudinal perforations and a plurality of impact bars longitudinally aligned with the perforations. The hot fluid impinges on the impact bars, and direct impingement on the tubes is avoided.

Abstract: A safe locking mechanism has an engagement element movable from a disengaged position to an engageable position in response to a small amount of electrical power. When in its engageable position a mechanical linkage assembly is driven by the engagement element to unlock a lock-bolt. The mechanical linkage assembly includes a low inertia pivoting cam which interacts with a lock lever of the locking mechanism to move it to an unlocking state. Electrical power is generated solely while the user manually inputs a combination code, and a microprocessor controls storage and delivery of this power to put the engagement element into its engageable position. Once the desired engagement is obtained, the lock-bolt is moved from its locking to its unlocking position manually. Subsequent unlocking requires another entry of the code input.

Abstract: The invention relates to a process for producing an immunogenic construct comprising activating at least one first carbohydrate-containing moiety with CDAP, and covalently joining the activated first moiety to a second moiety. Preferably, the first moiety is a polysaccharide and the second moiety is a protein. Immunogenic constructs are prepared by this process using either direct or indirect conjugation of the first and second moieties.

Abstract: Self-inking stamps and methods of reinking such stamps are disclosed. The self-inking stamps comprise a frame and a removable ink pad holder releasably mounted on the frame wherein the ink pad holder may be at least partially removed while the remaining structure of the self-inking stamp remains substantially intact to facilitate reinking of the associated ink pad.

Abstract: Safety element intended to assure in time the electric reliability of pulse transmitting leads, comprised in apparatus for the electric stimulation of the heart (pacemaker) and consisting of a main metallic coil of tubular structure delimiting an inner bore, covered by an insulating sheath, which safety element comprises a flexible lead formed by one or more wires coiled in tight turns or intertwined and provided with a rounded head for making it easier the introduction of the safety element in the bore of the main metal coil of the pulse transmitting lead.

Abstract: A device for recovering accumulated ink from a screen in a printing press, the screen having interstices corresponding to printed indicia, the device comprising means for applying the screen with ink while travelling along the length of the screen in a first direction, first means for generating a signal when said ink applying means has reached a desired point of travel after printing, means for stopping travel of said ink applying means in response to said signal from said first signal generating means, second means for generating a signal when recovery of ink is desired, and means for permitting further travel of said ink applying means in response to said signal generated by said second signal generating means, and lowering said ink applying means.

Abstract: A method for deinking paper pulp, wherein the batch of pulp to be deinked is made to circulate to move from top to bottom whereas the air bubbles are introduced at least in the lower part and move from bottom to top, characterized in that the pulp descends from top to bottom while being recycled in several consecutive and superposed stages.

Abstract: Staphylococcus aureus can bind a number of different extracellular matrix proteins. Recent studies have shown that one particular Staphylococcus protein has the capacity of binding several different matrix proteins. The gene encoding this staphylococcal protein has been cloned and sequenced and the nucleic acid and amino acid sequences are provided as a feature of the present invention. This staphylococcal protein has a high degree of homology with eukaryotic MHC Class II antigens. Further analyses of the binding specificities of this protein reveal that it functionally resembles an MHC II antigen in that it binds synthetic peptides. Additionally, the present invention provides a vaccine and an in vivo vaccine against staphylococcal infections, and methods for using same.

Abstract: A router bit for trimming the overhanging edge of a plastic laminate is provided having a rotatable shaft. A cutting tool is connected to the shaft and a cutting flute or wing is connected to the cutting tool. A ball-bearing guide rides along the apron of a plastic laminated top holding the cutting flute or wing in a spaced relationship to the plastic laminate. The shape of the cutting flute or wing employs two straight edges connected by a small radial section. A first straight edge is provided which lies at an angle of 5.degree. to 7.degree. with a portion of the side edge of the laminate. The second straight edge is provided which lies at an angle of 40.degree. to 60.degree. with a portion of the side edge and the top edge of the plastic laminate. The radial section, connecting the first straight edge to the second straight edge, has a small radius of curvature of 0.005 inches to 0.015 inches.

Abstract: A through-roof fitting seals a stack with a boot and seals the boot with a gasket around an opening in a sheet roofing created to receive the stack or pipe. An elliptical opening is cut in the roofing sheet. A base plate is placed below the sheet with a central raised portion of the plate extending through the opening cut in the roofing sheet. A flange on the base plate extends outwardly beneath the roofing sheet around the opening. A clamping plate is embedded in a combined boot and gasket so that the gasket extends over the roofing sheet around the opening when an elliptical step in the clamping plate is aligned with the projecting central portion of the base plate. The boot has successively inwardly stepped elliptical portions which terminate in a sloped top with a central opening for receiving and tightly engaging and sealing the pipe or stack. The embedded clamping plate has fastener openings which align with fastener receivers in the base plate.

Abstract: Acyclic hydrocarbons having 4 to 7 carbon atoms per molecule are isomerized in the liquid phase by contact with a solid superacid catalyst comprising sulfated oxide or hydroxide of a metal selected from the group consisting of Group III and Group IV metals, to obtain high octane number blending components for motor fuel and/or valuable chemical and fuel intermediates.
