Abstract: ABSTRACT           A unitary push button of a molded flexible plastic material adapted for pressing onto a stud provided with ridges extending generally radially and circumferen-tially therefrom.  The button is provided with an opening for accommodating the stud and expandable by the ridges when the button is mounted on the stud.  The button comprises a shank having a hole formed axially therethrough.          A flange is disposed at one end of the shank and blends into the shank.  The flange partially closes off the hole at the one end of the shank and the hole is opened at the opposite end of the shank.  A plurality of resilient fingers protrude radially from the wall of the hole at a predetermined angle toward the center of the hole and has an end face for engagement behind a ridge on  the stud and an opening formed through the flange for each of the fingers.  The openings extend axially from the outer surface of the flange into the hole and have an area to at least cover the cross-sectional area of the finger projected in a direction toward the opening.

Abstract: ABSTRACT OF THE DISCLOSURE       This invention provides a process for producing ethanol from a D-sugar in a continuous aerobic environment using a flocculant respiration-deficient mutant of Saccharomyces uvarum in a single stage fermentor with a cell settling tank and cell recycle, at a productivity of more than 50 grams ethanol per liter fermentor volume per hour.  The process comprises (a) inoculat-ing a fermentation zone with a respiration-deficient mutant of Saccharomyces uvarum; (b) feeding a mixture of a D-sugar, a nitrogen source, a vitamin source and a mineral source into the fermentation zone in the presence of oxygen, and (c) fermenting the D-sugar mixture for a sufficiently long period of time to yield an ethanol product.  In the process, the yeast are allowed to settle for a sufficiently long period of time and recycled to the fermentation zone to increase ethanol productivity.  The preferred D-sugar that may be used in the present process to produce ethanol, is D-glucose.

Abstract: ABSTRACT      The present invention relates to apparatus and method for separating, by centrifugation, blood lymphocytes from other leuko-cytes in a blood sample.  Small dense particles, either wetted or suspended in a physiological, hydrophilic medium, and a chemi-cally inert hydrophobic barrier material are initially located in a suitable container.  When the blood sample is added to the container, the particles are phagocytized by the monocytes and granulocytes, so as to increase their specific gravities.  Upon centrifugation, the barrier material, whose specific gravity is only slightly greater than the specific gravity of the lympho-cytes and less than the respective specific gravities of the phagocytic cells which have ingested particles and of the erythro-cytes (red blood cells) in the blood sample, forms a rigid barrier therebetween, allowing harvesting of the lymphocytes, substantially free of contamination.

Abstract: ABSTRACT OF DISCLOSURE        A drinking vessel comprises a first vessel member adapted to hold a liquid and a second vessel member associated with, but separated from, the first vessel member to form a barrier against the formation of condensation on the exterior surface of the second vessel member when a cold liquid is contained in the first vessel member.  In one embodiment, the first vessel member comprises a removable insert which conforms generally to the configuration of the second vessel member to form a double-walled drinking vessel.  Advantageously, a sanitary lip extends downwardly from the top edge of the insert and is proportioned and oriented to prevent a person's lip from contacting the second vessel member when the person takes a drink.  Also advantageously, the drinking vessel includes ribs or serrations, or, preferably, a plurality of protuberances and engagement ridges, ridge segments or recesses associated between the insert and the second vessel member to provide a secure friction fit therebetween yet permit removal of the insert for disposal and subsequent replacement.  In another embodiment, the first vessel member comprises a bowl member for holding a liquid and the second vessel member is a hollow stem member supporting the bowl from its base.  A collar-like ridge is formed generally at the junction of the stem for collecting any condensation and directing it into the stem.  The structure may be formed in two-piece structure or an essentially unitary structure.  The structure may, however, include a detachable stem base portion or a stopper-plugged hole in the stem base to facilitate removal of the accumulated moisture.

In the preferred embodiments half cylinder or quarter cylinder shaped segments are incorporated as the diamond cutting elements within teeth disposed on a rotating bit.  The planar surface or surfaces characterizing the cylindrical segments are oriented within the tooth to provide the leading and cutting face of the diamond cutting element.  Typically, such planar surfaces are entirely exposed and disposed adjacent to and form one wall of an adjacent and preceding fluid channel whereby cleaning and cooling efficiency is also improved.     page 1

Abstract: TOILET-BOWL BIDET APPARATUS            ABSTRACT          An add-on bidet includes a moulded plastic seat (12) which has a channel-shaped cross-section.  A pivoting spray-arm (106) is stowed between the toilet-bowl rim and the inside of the channel. The inner wall (16) of the  seat acts as a splash guard.  The  spray-arm  is mounted in bearings (214,102) which are formed in the walls (16,18) of the seat. The seat is able to pivot, for  raising,  on a pair of stubby pivot pins (36,38) widely spaced apart.  One (38) is hollow,  to  convey water to the seat. There are no exposed hose pipes or other  obtrusive components.  The water control knobs (70,71,76) are accessibly located.  Water leaves  the spray-head  (116) as a coherent tube of water,  which gives rise to a soft, gentle stream, whether the flow volume  is  large  or  small.  This  is  achieved  by deflecting  jets  of water from nozzles so  that  the jets coalesce back into a stream.

Abstract: ABSTRACT OF THE DISCLOSURE     A process for the recovery of germanium includes acid leaching of germanium-containing oxidic material and neutralization to pH 3-5 in the presence of ferris iron, whereby a precipitate is obtained.  The precipitate is releached in acid and the leach slurry is reduced with at least one reductant chosen from zinc sulfide concentrate, lead sulfide concentrate and iron.  Preferably, lead sulfide concentrate and iron are used in a two-step reduction following the reteach.  Germanium in the reduced solution is precipitated as germanium sulfide.  The use of lead or zinc sulfide concentrate and iron results in a reduction of arsenic and antimony in and a substantial elimination of copper from the germanium sulfide-containing concentrate.

The microphone portion is angled about 38 degrees from the handle.  The handle has a width of about 1.5 inches and a depth of about .7 inch to meet the requirements of 98% of the user population.  A speaker portion, angled about 15 degrees from the handle, has a concave depression to be seated against a user's ear.  The distance between the center of the speaker depression and the microphone cavity is about 5.8 inches.  The microphone portion is about two inches long and has grooves extending to its end.  Baffles extend across the hollow of the handle to acoustically isolate the speaker and microphone portions of the handset.  To facilitate assembly, the connector and microphone are first fixed to a holder without the need for adhesive or additional fasteners. The speaker and holder are then positioned in a base section of the handset without the need for adhesive or additional fasteners.  The holder may restrain a magnet element.  A top section of the handset is secured under a lip at one end and by a spring clip at the other end.
