Abstract: TITLE:  LOG CHOKER HOOK                     Abstract of the Disclosure A choker hook slideably mountable to a winch line and receiving one end of a choker cable or chain.  The hook is comprised of an elongated body having an opening for receiv-ing a winch line.  The body will slide freely along the winch line.  A lower portion of the body is bifurcated to define an open recess.  A choker cable loop or an eyelet of a "keyhole grab" may be received within the recess.  A threaded pin is provided to threadably connect the bifurcations and selectively close the recess.  A sheave is rotatably received on the pin and may be located within the recess to receive a portion of a cable loop.  The pin may be easily removed and attached to the choker hook body to facilitate quick attachment and removal of a choker cable.  If a "keyhole grab" is being used, the sheave may be removed.  The pin alone is then used to close the recess.

Abstract: METHODS OF MAKING FEMININE HYGIENIC  PADS WITH ANTERIOR LEADING EDGES        ABSTRACT        Methods of making feminine hygienic pads from non-layered and layered material by use of folding, pres-sure molding and various methods of bonding to create a long geometric form with an anterior leading panel of narrow thickness and a thicker posterior underpanel of a wider thickness. The folded panels may be bonded by either a suitable adhesive, crimping, heat, pressure or ultrasonic means leaving an anterior portion with a lead-ing anterior edge and a larger posterior portion.  A filler may be inserted between the folds of the material prior to bonding.  Thereafter, the long geometric form is multiply cut transversely providing pads about two inches long.  These pads are used for insertion into the female interlabial space.  The geometric configuration of the pads facilitates insertion of the pad via the an-terior leading edge into the interlabial space and has improved retention within such space.

Abstract: ABSTRACT            A method for treating gaseous combustion products, in particular, combustion products containing sulphur dioxide and smoke gases.          The combustion products are led to a scrubber in which they are brought into contact with scrubbing water, into which a base, pre-ferably calcium hydroxide, has been added for obtaining suitable neutralization of the acids created in the scrubber. The scrubbing water is sprayed into the gaseous combustion products, preferably in the form of a finely divided mist, and after the scrubbing ope-ration the combustion products are led through a heat exchanger for cooling and for recovery of condensation water. The scrubbing water used and the condensation water are collected in a settling tank, at the bottom of which solid impurities are caused to settle for removal at suitable intervals. The purified surplus water is led from the settling tank and is reintroduced into the scrubber.          The amount of base mixed into the scrubbing water for converting the acids created in the scrubber into settling salts, is so cho-sen, that the pH value of the liquid in the settling tank is 7-10, preferably 8-9.

Abstract: Abstract of the Disclosure A system and method for fixedly securing a roller side bearing assembly to the top surface portion of a rail car truck assembly.  Elongated threaded fasteners pass through registered openings in a bearing cage bottom wall and truck assembly top surface portion in threaded receipt by locknuts disposed on the underside of the top surface portion.  A washer captured on each fastener includes at least a portion thereof which is closely interposed between the fastener head and the bearing cage bottom wall at the associated opening.  The fasteners are rotated into threaded advancement with the locknuts to achieve fastener clamploads which fall within predetermined upper and lower limits.  Each fastener head advantageously includes a hex type wrench receiving opening which has a limited maximum torque capacity generally correlated to obtaining a fastener clampload no greater than the predetermined upper limit.  The washer geometry facilitates use of better or improved fastener head fillets.  In addition, the fasteners advantageously have undersized bodies or shanks immediately adjacent the heads to reduce bending stresses experienced therein.  The overall structural features and manner of installation provide a fatigue resistant, somewhat torque limiting roller side bearing mounting system and method.  The results obtained enable the fasteners to withstand periodic bending loads applied thereagainst during normal rail car use.

Abstract: ABSTRACT OF THE DISCLOSURE     Longitudinal grooves and/or ribs (2a,2b,2c) depart from the card's (1) forward extremity (1a), likewise two similar rows of toothing (3) occupying a limited portion of the card. The obliterator is furnished with a slot (30) accessible from without, whose cross-section complements the card's transverse profile and whose two longitudinal grooves (32a,32b) serving to accommodate the said tooth-ings (3) give place to teeth of corresponding small cog-wheels (36a,36b) idling on respective shafts. Insertion of the card (1) into the slot (30) causes gear-pairing of the cogwheels (36a,36b) with the toothings (3), intercep-tion, or not, of mechanical tracer points (24,25,33,34,37) linked with corresponding micro-switches (24a,25a,33a,34a, 37a), with predetermined areas of the card, with consequent excitation of an electromagnet (16) commanding a blade (19) which clips a paring (Z) from the card's (1) forward extre-mity  (1a) ;the number of clippings equates to the number of teeth (3a) in each of the card's toothings and the final clipping may be effected only when individual micro-switch (34) is inserted into the corresponding aperture (45) located within the card itself. Each accomplished clipping occasions activation of a corresponding micro-switch (18a) which in turn activates a drinks/services vending unit (50).

Abstract: ABSTRACT           Glass sheets having controlled reflection and transmission spectra in which a metallic reflective layer deposited on the surface of a glass substrate is coated with a protective layer consisting of a cadmium and tin oxide mixture wherein the atomic ratio of the cadmium/tin is between about 0.2 and about 10.  Alternatively, the metallic reflective layer is deposited on an anchoring layer which is deposited directly on the surface of the glass substrate. The anchoring layer advantageously consists of a cadmium and tin oxide composition identical to that utilized to form the protective layer.  According to the present invention, the transmission and reflection spectra of a glass sheet can be modified by controlling the thickness and/or composition of each layer, particularly the composition of one or more of the cadmium-tin oxide layers, to produce glass sheets which exhibit excellent transparency in the visible spectrum and high reflection in the thermal infrared spectrum, thereby reducing energy losses.
