Abstract: ABSTRACT     A weather sealing arrangement for a gap between first and second elongate structural members of which a door equipped with a weatherboard, and a sill, are examples, in which the weatherboard supports an elongate seal therealong which has a resiliently supported protruding portion for sealing a gap between the weatherboard and the sill when the door is in a closed condition, and the sill provides a weather strip which extends along the sill and protrudes therefrom.   During hingeing movement of the door from the closed condition to an open condition, the protruding seal passes through an intermediate condition in which the seal portion traverses the weather strip so that the whole length of the seal portion is wiped by the weather strip and rain-water will tend to be wiped off the seal portion and so be kept outdoors.   The weather strip is in the form of a rib which may be elastomeric and removably secured to the sill, or formed on it and be moulded with the sill.   In the closed condition the seal portion and rib may be backed up by the door;  the seal portion may seal against the rib, or the sill, or both the rib and the sill.

Abstract: PATENT APPLICATION   of JOHN D. PSARAS       and LEROY R. SACHLEBEN for A METHOD AND APPARATUS FOR MOISTURIZING TOBACCO STEMS                 ABSTRACT OF THE DISCLOSURE      Whole tobacco stems are uniformly moisturized by opening the cellular structure of the stems and inducing moisture to permeate the opened cellular structure.  By an initial and simultaneous application of water and steam, the cellular structure of the stems is opened, and moisture permeates the structure to a first induced moisture content.  Thereafter, the stems are equilibrated with the moisture diffusing throughout the cross-section of the stems.  Subsequent to equilibration, the stems are moisturized to a second induced moisture content by initially applying water to the stems and thereafter a mixture of water and steam.

Abstract: ABSTRACT OF THE DISCLOSURE      A process for the production of pile-surface material which comprises the steps of interposing a thermo-plastic material between a backing and a substantially smooth heated surface, holding the backing against the thermoplastic material so that bonding of the backing to the thermoplastic material and adhesion of the material to the heated surface occurs, parting the thermoplastic material from the heated surface over a bar which provides a curved path having an initial radius of between 1 mm. and 8 mm. so that fibrils are drawn out from the thermoplastic material between the heated surface and the backing and hardening the fibrils as they are drawn out by a stream of cooling fluid.    The present process seeks to improve both the uniformity of pile produced by this type of process, to allow uniform piles to be produced at higher speeds than before possible and to provide a versatile process which is readily adaptable to produce varying types of pile.

Abstract: Processes are provided herein for the catalytic production of formaldehyde.  In particular, the inventive process for the production of formaldehyde from methanol includes the passage, at an elevated temperature, of methanol through a specifically recited catalyst, e.g., by passing a gas stream containing methanol and oxygen or gaseous methanol and oxygen through the catalyst under specifically recited conditions of temperature, pressure and space velocity.  The catalyst comprises a monolithic metallic or ceramic support, e.g., corrugated metal foil or corrugated and plain sheets of metallic foil provided with channels for passage therethrough of the gas stream.  The channel wall surfaces are coated or impregnated with one or more of copper, silver, gold and iron.  It is believed that one factor contributing to the success of the process of this invention is that the extended metal substrate oxidizes in such a way that the first layer of oxide film does not tend to grow over or cover the outermost layer of the catalyst metal, e.g., iron, copper, silver or gold.

Abstract: UNITED STATES PATENT APPLICATION        OF                         ROGER J. CURRAN                             FOR           EXTRACTOR ASSEMBLY FOR RIMLESS CARTRIDGES     ABSTRACT OF THE DISCLOSURE     Disclosed is an extractor assembly including an extrac-tor rod splined within a revolver cylinder and carrying spring leaf extractor segments in elongated grooves about its outer sur-face.  The segments are prebent and biased in the assembly to displace extractor tips carried thereby radially outwardly.  When the extractor assembly is fully seated within the revolver cylin-der, cam surfaces on the cylinder maintain the extractor tips spaced radially inwardly of the cylinder chambers.  Upon axial displacement of the extractor assembly, the extractor tips, under the natural bias of the segments move radially outwardly into the grooves of the cartridge casings whereby the tips displace the casings rearwardly from the cylinder chambers.  Upon spring return of the extractor assembly into the cylinder, the extractor tips are cammed radially inwardly and out of the chambers enabling the cylinder to be loaded.

Abstract: METHOD OF MAKING FILTER BOARD                     Abstract of the Disclosure Beads of expandable polystyrene are expanded to a density of 0.4 to 0.6 pounds per cubic foot, using a two-step process in which the beads are expanded to a density of about 1 to 2 pounds per cubic foot in a first step, and then to a density in the above-mentioned range.          Thereafter, after a suitable length of storage, like 4-30 hours, the beads are used to make filter boards, by being placed into a mold and treated with steam, caused to expand to the desired final dimensions, and fused together.          If cut, the pieces so molded are divided with the use of a saw, hot wire, or similar mechanical means.  This makes it possible to produce filter boards with the use of an extremely short molding-cycle time and a correspondingly increased production rate.  Such filter boards do not decay nor support the growth of fungus or mold, and they are eminently suited as drainage boards in the agricultural industry.

Abstract: MATERIAL TRANSFER SYSTEM     ABSTRACT OF THE DISCLOSURE         A material transfer system for transferring parti-culate material from a first fluidized bed to a second fluidized bed includes a rectangular, vertically-aligned downcomer communicating at its lower end with a rectangular, horizontally-aligned exhaust duct.  A sparger assembly having plural gas injection tubes communicates with the exhaust duct and is provided to direct horizontally spaced gas flows into the exhaust duct.  A control valve coupled to the sparger assembly selectively starts and stops the flow of an activating gas to define gas flow pulses having a selected pulse duration.  Particulate material from the first fluidized bed enters the downcomer through a catch pocket formed at the upper end of the downcomer and fills both the downcomer and the exhaust duct.  The gas flow pulses entrain the particulate material in the exhaust duct and transport it through an outlet into the second fluidized bed.

Abstract: ABSTRACT OF THE DISCLOSURE         A solvent vapour collector is mounted on the upstream inlet end of an oven having a gas-circulating means and intended for curing a coating applied to a strip sheet metal at a coating station.  The strip sheet metal may be hot and solvent vapours are evaporated at the coating station and from the strip as it passes from the coating station to the oven.  Upper and lower plenums within a housing of the collector are supplied with oven gases or air from the gas-circulating means and such gases or air are discharged within the collector obliquely in a downstream direction against the strip passing through that collector to establish downstream gas flows along the top and under surfaces of the strip so as, in turn, to induct solvent vapours into the collector at the coating station.  A telescopic multi-piece shroud is usefully provided on the housing for movement between an extended position in which it overlies the coating station to col-lect solvent vapours released thereat and a retracted position permitting ready cleaning and adjustment of that coating station.

The disc transducer element is positioned to transmit acoustic energy in  direction parallel with a borehole axis and this energy is reflected by the conical reflector so that it impinges upon a borehole wall near the critical angle to provide maximum propagation of energy in the rock in one direction parallel to the borehole. The same transducer arrangement also functions as an efficient directional receiver of acoustic energy.
