Patent NO-160146-C (NO)
Inventor: BRACKE JAMES W
IPC: C07H5/04
Filed: 1984-10-15
Abstract: Hyaluronic acid, a polysaccharide, is prepared in high yield from streptococcus bacteria by fermenting the bacteria under anaerobic conditions in a CO2-enriched growth medium, separating the bacteria from the resulting broth and isolating the hyaluronic acid from the remaining constituents of the broth. The bacteria may be grown free of endotoxins by filtering all ingredients through a 10K Millipore TM filter prior to inoculation of the medium and subsequently maintaining pyrogen-free conditions. Separation of the microorganisms from the polysaccharide is facilitated by killing the bacteria with trichloroacetic acid. After removal of the bacterial cells and concentration of the higher molecular weight fermentation products, the hyaluronic acid is isolated and purified by precipitation, resuspension and reprecipitation.

Abstract: The invention concerns woven straps having transverse contractions, as well as a method and apparatus for their manufacture. Contractions are formed along straps having a continuous unchanging weave and continuous selvedge by altering spacing of warp yarns during weaving. The warp yarns are spaced by a V or fan shaped support which is vertically movable to cause corresponding width variations in the straps.

Date Jan. 3, 1986.A method and a device for placing edge protecting means (7) at objects in connection with band strapping. The inventive method is distinguished in that blanks for edge protecting means (7) are fed as a continuous band (7a) which when advanced is preliminary bent around a longitudinal line, that the fed-out portion of the band (7a) is cut to form an edge protecting means (7) in correct position, and that the edge protecting means (7) is finally bent in connection with cutting. The inventive device is characterized in that a magazine containing blanks for edge protecting means in the form of a band (7a) is secured to a body (6) supporting a feeding mechanism (8-17) for said band which comprises means (8) for preliminary bending the band (7a) around a longitudinal line, a cutting means (30) being fixed to the body (6) serving to separate, after feeding the band a predetermined distance, the fed-out portion of the band as an edge protecting means (7), a bending means (30, 32) thereby being arranged to finally bend the edge protecting means (7) on separation thereof.

Abstract: A means for dispersing paper, cardboard and pulp, comprising a basin (1) open on top, into which the raw material to be dispersed is fed e.g. from a paper machine located thereabove, and wherefrom it is removed when dispersed with the aid of a pump, and one or several dispersing units (3) placed on the wall (6) of the basin (1), preferably a rotor/rotors. A problem with this kind of apparatus known in the art is that the pulp-circulation effect of the dispersing rotors is poor, whereby the material to be dispersed cannot enter the effective range of the rotors well enough. With the aid of the invention, the problem is solved in that one or several mechanical or flow-technological apparatus (7) providing pulp flow for the rotors is mounted on the wall (5) of the basin (1) opposite to the rotors (3).

IPC: H04L12/70

Abstract: In high-speed packet switching, packets of specific connections (CS1, CS2), e.g. speech, moving image, are to be handled with higher priority than packets of other connections (PS1, PS2, PS3), e.g. data, without delay jitter and without losses. 
<??>In a known method, a division is made into a line-switching component (for CS1, CS2) and a packet-switching component (for PS1, PS2, PS3). The line-switching component operates using synchronous time-division multiplexing. In each case, for example, 70 packets, each comprising 40 octets, are combined on each input line to form a frame. Without special measures, this would produce delays in each switching stage of the order of 40 x 70 x 8 bits = 22,400 bits; for each input of a switching stage 22,400 bits of memory space would be required. 
<??>According to the invention, all packets are divided in the exchange into packet parts of equal length and distributed among sub-frames. Switching is carried out on the basis of sub-frames. Delays and memory space requirements are reduced by the frame : sub-frame ratio. 
<??>Fixed positions are preferably allocated to the higher-priority connections (CS1, CS2) in each frame and each sub-frame for the entire duration of the connection. 
<??>Packet parts of the remaining packets are preferably arranged in sequence in remaining free positions and re-combined within each switching stage to form complete packets.

Abstract: This extendable antenna is related to an extendable antenna for a portable radio transceiver.     The antenna has a first antenna portion and a second antenna portion connected with a connecting portion of the first antenna portion. The first antenna has a loading coil which is enclosed in a top end cap. When the second antenna portion is retracted into a housing, the connecting portion is held by a holding member disposed in the top of the housing, and the connecting portion is ellectrically connected with the circuitry of the transceiver via the holding member. Furthermore, the electrical length of the loading coil is a quarter wavelength, while the physical length of the loading coil is ?uch less than a quarter wavelength.     Accordingly, even if the top end cap is only located out of the housing. the first antenna portion detects a radio frequency signal.          Furthermore it is unnecessary for the radio transceiver to have an inner antenna and a rod antenna. and switching means for switching from the rod antenna to the inner antenna. And it is unnecessary for the housing to have space for the the inner antenna.

Title: Vehicle simulation circuit for inductive-loop traffic signal control systems
Inventor: STRANG CLIFFORD B
IPC: G08G1/042
Filed: 1991-05-17
Granted: 2000-12-19
Abstract: The present invention provides a simulator which when used aboard a vehicle normally undetectable by a traffic signal control system (e.g. A.C. energized buried sensing loop type which detects predetermined changes in the characteristics of an electromagnetic field due to the presence of a detectable vehicle therewithin), will substantially simulate the characteristics of a detectable vehicle within its field and thereby cause any activation of the system. Operationally, the simulator derives an electrical signal from the field (e.g. via a receiving antenna), converts the electrical signal into a modified transmittable signal of an amplitude which when impressed upon the field (e.g. via a transmitting antenna) simulates electromagnetic influence of a detectable vehicle therewithin which is sensed by the detector circuitry and activates an associated traffic signal controller to provide the necessary signals (e.g. a green arrow) to allow safe and unobstructed traffic flow at an intersection.

Abstract: A method and apparatus for the production of a fuel from the decomposition of water and the subsequent use of this fuel as an energy source in an internal combustion engine or in a system for generating heat.  The method comprises the steps of:  a)    mixing water and a hydrogen-based source material under pressure to create a mixture;  b)  creating turbulence in said mixture;  c) heating said mixture to the point that the water molecules within the mixture begin to dissociate.  The apparatus of the present invention comprises a first pump to pressurize water and a second pump to pressurize the hydrogen-based source material.  The pressurized water and hydrogen-based source material are pumped into a mixing tank where they form a mixture.  A turbulence-creating mechanism is connected to the mixing tank and the mixture is passed through the turbulence-creating mechanism where it is heated to a temperature sufficient to cause decomposition of the water molecules therein.   The mixture is heated to this temperature by a heat applying mechanism which contacts the turbulence-creating mechanism.  The mixture is ultimately fed into a combustion chamber where it is ignited by a combination of compression and a spark from a spark plug.
