Abstract: METHOD AND APPARATUS FOR CLEANSING AND DISINFECTING        TOILET TANKS AND BOWLS             ABSTRACT         Method and apparatus for cleansing and disinfecting a toilet tank and toilet bowl by treating the water dis-charged from the toilet tank each time the toilet is flushed. A passive dosing dispenser that automatically dispenses a disinfectant with each flush is provided in the tank to carry out the cleansing and disinfecting method.  The dispenser com-prises a series of chambers in fluid communication including a reservoir containing the source of disinfectant, a vented volume control chamber, a delivery tube provided with a dis-pensing orifice in dynamic fluid communication with liquid in the toilet tank, and a vented standpipe.  The respective cham-bers have volumes selected to provide a controlled dispensing action, and the arrangement of chambers is such that the con-centration of the aqueous disinfectant solution discharged re-mains substantially constant upon repetitive flushing, and/or during extended quiescent periods.  The dispenser can be pro-vided with means responsive to toilet tank and toilet water con-taminants that tend to interfere with the disinfectant dis-pensed.

Abstract: Abstract of the Disclosure Method and apparatus for neatly and efficiently coating microscope slides with a staining liquid.  One or more slides are dipped into a pool of liquid partially fill-ing a chamber in a container.  The chamber has a cross-section conforming closely to the slide exterior so that slide im-mersion causes the liquid level to rise upwardly and cover all those portions of the slides which may contain a specimen to be stained.  To stain a multiplicity of slides simul-taneously, the slides are clamped in a holder between spacers which hold them parallel and spaced apart by a small predetermined distance, and the clamped slides are then held by the holder during subsequent immersion and removal.  A special inexpensive arrangement of case and slidable drawer with wedge-shaped side portions is used to facilitate fast clamping and unclamping of the slides.

Title: Method of steel production from solid iron-containing   material
Inventor: CHITIL MANFRED
IPC: C21C5/34
Filed: 1983-06-28
Granted: 1986-12-16
Abstract: ABSTRACT OF DISCLOSURE           This invention relates to a method of producing steel from solid ferrous material (such as scrap) in a converter.          According lo the invention, in each converter cycle, after scrap charging, a portion of a liquid charge originating from a preceding converter cycle is poured over the scrap.  The total charge is melted down by injection of fuel and oxygen through melt-submerged injection nozzles.  The tapped output is either (for repeat cycles) tapped into two holding vessels the content of which is used as liquid charge for the next two following charges, or (for production cycles) the whole tapped amount of steel is used for further processing, for example in a foundry.  In that case, the steel melt is fully refined prior to topping.

Dompas ABSTRACT OF THE DISCLOSURE          Process and apparatus for continuous casting in a twin-belt casting machine in which the moving side dams are guided along opposite sides of the moulding cavity by guide means extending along beside the respective moving side dams, and the moving side dams are cooled by cooling fluid circulated in at least a part of said guide means and applied directly to the moving side dams.  The moving side dams are cooled by cooling fluid sprayed through orifices in said guide means directly onto the moving side dams along at least a part of the downstream zone of the moulding cavity.  During movement of the side dams along the moulding cavity from its entrance to its exit, they pass succes-sively through a first (or upstream) zone in which they face molten metal and through a second (or downstream) zone in which they face solidified metal. The cooling fluid is sprayed directly onto the moving side dams only in this second zone.          The first zone occupies from approximately 3/l0ths to approxi-mately 1/2 of the overall length of the moulding cavity, and the second zone occupies the remainder.   The cooling fluid is advantageously sprayed directly toward the side dam for provid-ing very effective cooling action, and this cooling fluid is aimed in a downstream direction that forms an acute angle with the moving direction of the side dam.  Preferably this acute angle is in the range from approximately 20° to approximately 50° for propelling the cooling fluid downstream away from the first zone, and preferably the cooling fluid is water.

Abstract: RADIO TELEPHONES HAVING IMPROVED TRANSMITTING AND RECEIVING CHARACTERISTICS            Abstract A radiotelephone system using portable radiotelephones (FIG. 2) utilizes two antennas but only one receiver section.  A terminal station (FIG. 1) transmits the same preamble signal in at least two time slots of a frame period of a time division sequence using the antenna receiving the strongest preamble signal from the portable station in the immediately prior frame period followed by a binary message signal using the same antenna.  The portable station receives each of the preamble transmissions from the terminal station via both of differently oriented antennas and determines which antenna received the strongest signal.  The message signal from the terminal station is then received via the antenna of the portable station having received the strongest signal, the portable station also sends its response message signal on that antenna during a separate time slot of a frame period.

Abstract: ABSTRACT    A system for generating a real time perspective view of the terrain lying along an aircraft's flight path accesses terrain data stored in a digital map generator and converts the data into a perspective representation of the terrain on the face of a suitable display such as a cockpit instrument panel CRT.  The stored map data that is accessed provides, in real time, information pertaining to elevation features of the terrain over which the aircraft is flying, so that upon conversion to a perspective presentation to the pilot, there is provided a real time perspective image of the contours of the terrain as though the pilot were looking out a windscreen at the terrain in high visibility conditions.  The invention also is capable of providing perspective scene rotation and translation (corresponding to roll and pitch of the aircraft).
