Abstract: OPTICAL FIBER CONNECTOR          Abstract of the Disclosure The present invention relates to an optical fiber connector.  The connector is comprised of a connector body having a frustum-shaped mating portion which tapers from a large diameter to a point along the connector body to a smaller diameter end surface.  An aperture extends longitudinally and coaxially along the connector body.  A single optical fiber is located in the aperture and is affixed to the connector body.  The single optical fiber terminates near the smaller diameter end surface of the mating portion.  A transparent flexible contacting member is provided, extending over the end of the optical fiber and a portion of the end surface of the mating portion.          The contacting member has a dome-like shape.  Problems related with variations in the physical size of the connector are substantially eliminated by using the frustum-shaped mating portion. The latter maintains the symmetry and centering of the optical connector resulting in accurate and reliable fiber alignment and consequently low coupling loss.

Abstract: DRAINAGE DEVICE WITH SEPARATE OUTFLOW CHAMBER            ABSTRACT        A drainage device is provided with a collection chamber, underwater seal chamber and a separate outflow chamber.  The underwater seal chamber which prevents the flow of atmospheric air from the device into the pleural cavity of the patient is formed by a recessed portion in a partition separating the un-derwater seal chamber from the collection chamber.  The passage-way from the underwater seal chamber into the collection cham-ber is disposed centrally of the partition separating the cham-bers and a baffle is formed around the opening to prevent ex-cessive loss of fluid from the underwater seal chamber into the collection chamber when the device is inadvertently tilted.  The outflow chamber is closed off from the collection chamber and is connected with the underwater seal chamber by means of a tubular passageway adjacent the upper wall of the drainage ap-paratus so as to prevent fluid from passing from the underwater seal chamber into the outlet passageway.  A oneway valve is provided in the outlet chamber to prevent backflow of air from the atmosphere into the device but which permits outflow of air from within the device when the air pressure within the device is higher than atmospheric pressure or when the device is used with a suction pump.  A hanger attachment is provided to permit the device to stand on the floor or be hooked onto the bedside.

Abstract: Abstract Disclosed are sampling devices for detecting particulate contaminants, particularly radioactive particulate contaminants, in a gaseous medium, such as air.  The devices use filters comprising a filter membrane sandwiched between two pieces of plastic material having holes exposing the filter membrane to the gaseous medium.  Each filter is moved between a sampling position at which the filter is exposed to the gaseous medium and a measurement position at which the amount of particulate material collected by the filter can be measured.          In the measurement position, a gas-tight seal may be formed with the plastic surrounding the filter medium so that the chamber holding the filter may be evacuated for measurement of radio-active particles.  The filter may be moved linearly or rotationally.  The detector may comprise a detector of radio-active particles.

Abstract: A NEW SYSTEM FOR DRYING AND BURNING VISCOUS    AQUEOUS LIQUORS WHICH CONTAIN ORGANICS     ABSTRACT OF THE DISCLOSURE     Sawdust is mixed with partially concentrated black liquor from pulp manufacture.  The sawdust, coated with the solids of the black liquor, is dried by heated air.  The sawdust, coated with organic and inorganic black liquor solids, is fed to the hearth of a chemical recovery boiler.  Combustion of the char formed on the boiler hearth produces heat which causes additional organic material to pyrolize.  The inorganic material combines to form molten smelt. The moisture-laden, heated air from the dryer is introduced into the boiler with the secondary air and the smelt is tapped off into an aqueous solution to form green liquor.

Abstract: Case 611 Abstract of the Disclosure In accordance with the present invention a hatch cover hold down arrangement is provided including a handle which pivots about a first mounting pin.  The handle in-cludes an elongated locking slot.  A locking member in-cludes an extension which in one position is located over and holds in place a hatch cover.  A locking pin extends from the locking member into the elongated slot in the handle and a mounting pin slot is provided in the locking member which receives the mounting pin upon which the handle is pivotably mounted.  Preferably the mounting pin is supported by a flange located adjacent to the locking member which includes a vertical surface which guides the locking member during vertical movement between open and closed positions.  The locking member includes a surface which engages the flange vertical surface as the locking member is lifted by the handle and locking pin from the closed position toward open position and prevents initial rotation of the locking member.  However, when the handle pivot pin bottoms out in the bottom of the slot in the locking member, the pressure within the car has been relieved and the locking member moves with the handle to a position which no longer obstructs the cover.

Abstract: ABSTRACT In a process for the production of titanium dioxide by the vapour phase oxidation of the titanium tetrachloride in which process entrained inert particulate material is passed through equipment used to reduce or prevent the deposition of solids thereon, the quantity of inert particulate material en-trained may be affected by the varying back pressure normally obtaining in the equipment.  The control of this quantity may be improved by reducing pressure differences by means of conduit between the inlet and outlet of a mechanical feeding device for the solids.  This entails the transmission of the pressure from the conduit into the solids delivery system and this may be alleviated, optionally, by maintaining a head of solids in the system and/or by using a system of pressurised hoppers.  The invention enables the quantity of inert particulate material used to be reduced.

Abstract: "COIN OPERATED CAR WASH CONTROL ASSEMBLY" ABSTRACT OF THE DISCLOSURE:          Coin operated car wash assemblies usually include a selector and means to insert coins to obtain the necessary wash, rinse or other functions and when the time has expired, further coins have to be inserted.  Furthermore each function has to be called up and completed before additional coins can be inserted for the next function.  For example, coins have to be inserted for the wash cycle and then when that is complete-ed, further coins have to be inserted for the rinse cycle. The present device allows the car wash assembly to be used by the user for various functions and for various times.  With the provisions of two individual timers, any two functions can be requested and paid for and times accumulated.  Furthermore the user can switch functions at any time and can add additional money at will.  A comparator compares accumulated time with used time and switches off the system when these times match. The operator can preset two individual times for the various functions.  For example wash and rinse can be for one time period costing a certain amount of money and functions such as engine wash, waxing, rust inhibiter, etc. can be set for a different time period and for a different amount of money.

Abstract: ABSTRACT OF THE INVENTION        A communications system capable of simultaneously transmitting voice and data information.  The spectral energy of the data signal is smeared by spreading it in a spectrum with energy packed in the lower frequency range under the conventional voice signal frequency in a manner which complements the standard C-message weighting curve.  The use of the spread spectrum technique also eliminates thumping at the data rate since the harmonics that produce thumping are also spread throughout the bandwidth.
