Patent BR-PI0107925-B1 (BR)
Inventor: IMMONEN OLLI
IPC: H04W12/10
Filed: 2001-02-01
Abstract: The invention relates to a method for checking the integrity of a message transmitted between a sender in a transmitting end and a recipient in a receiving end, in which method an authentication value is calculated for the first message and a random string is generated. According to a method in the transmitting end an authentication value is generated from a message to be sent and the random string. A check code is formed from the authentication value and the random sting. The first message is transferred from a sender to a recipient through a first channel, and the check code is transferred through a second secure channel. In the receiving end a message is received through a first channel and the check code is received through a second secure channel. In the receiving end an authentication check formed at least based of the received message. The integrity of the received message is checked by comparing the predetermined check values in the receiving end.

Abstract: Sensors for the determination of organometallic compounds, e.g. n-butyllithium, comprise the following elements:   a)an inorganic, organic or polymeric support, insoluble in the sample to analyze b)an indicator which reversibly reacts with the organometallic compound and whose reaction product gives a characteristic absorption, reflection or emission band in the range 150-15000nm, e.g. 1,10-phenanthroline and derivatives, triphenylmethane, or N-Ä2-(4-hydroxybenzyl)phenylÜ-2,2-dimethylpropanamide, and which is physically trapped, adsorbed, absorbed, dissolved or chemically linked in an electrostatic or covalent way to the support c)an optical sensor which measures the absorption, reflection or emission of the functionalized support at the characteristic wavelength and transforms it in the concentration of the organometallic present in the solution. Also described is the method for the determination of the concentration of organometallic compounds by the on line use of a sensor in anionic polymerizations.

IPC: A46B15/00
Filed: 2002-03-21
Abstract: A method is proposed for analysing the usage of a toothbrush made by a subject. The position of the toothbrush is monitored using a position sensor on the brush, and the position of the teeth is monitored by a position sensor mounted in a known fixed relation to the teeth. The resultant data is used to find the relative positions of the toothbrush and teeth over time. Statistical analysis of this data permits the identification of habitual brushing failures by subjects of the toothbrush. The toothbrush may transmit the output of its position sensor to a data analysis unit as a wireless signal. The toothbrush may also be provided with further sensors, such as pH and pressure sensors, the output of which is used in the statistical analysis to enrich the results.

Abstract: Obvod pro kontinuální přepojení odporů
a zrychlovače tramvají je realizován
zapojením čtyř stykačů v obvodu elektrodynamické
brzdy, při jejichž funkci nedojde
k přerušení brzdného proudu. Účelem
řešení je zamezení selhání brzd a
vyloučení havárií stávajících dvoj stykačů
při přerušovaném přepínání proudu
brzdových obvodů tramvají vybavených
zrychlovačem s reverzovaným zapojením a
Chodem. Podstata řešení spočívá v tom,
že v jednom pólu generovaného napětí
trakčních motorů jsou zapojeny dva stykače,
kterými se uzavírá obvod náběhového
odporu a jedné poloviny zrychlovače,
zatímco v druhém pólu jsou zapojeny další
dva stykače, kterými se uzavírá obvod
druhé poloviny zrychlovače a brzdového
odporu. Postupnou funkcí stykačů se
přepojuje konstantní brzdový a náběhový
odpor s regulovaným odporem obou polovin
zrychlovače tak, že při brzdění vozidla
z vyšších rychlostí do nižších nedojde
k přerušení brzdného proudu. Sled spínání
a rozpojení jednotlivých stykačů se
dosahuje pomocí reverzačního relé a
pomocných doteků stykačů zapojených
v obvodech jejich cívek na ovládací napětí.

Title: Numbering mechanism control for rotary printer - enables complete regulation any point in time without stopping machine
Inventor: ZEISER ALOIS
IPC: B41K3/12
Filed: 1975-01-15
Abstract: A control strip is passed over a pressure roller and the roller and strip can be pressed for a short time onto the numbering printing mechanism. The pressure roller is rotatably mounted in a swivel frame which is axially displaceable but cannot rotate on a traverse shaft fixed to the housing of the rotary printing machine. The traverse shaft can be operated by a hand lever in order to swivel the frame between an inoperative position of the control unit and a pressure position for the roller. The inoperative and operative positions are determined by stops which in each case limit the rotary movement of the traverse shaft. The control unit is swivable under its own weight into the inoperative position.

Inventor: MACK KARL
IPC: F28F19/00
Filed: 1979-03-12
Abstract: To fill up the ring-shaped gaps between the tubes and fins of a tube and fin type heat exchanger with a corrosion protective hardenable filler, a unit made up of two closing pieces with filler material between them is pushed by means of the tube to be inserted in the stacked fins through the space formed by the collars of the openings in the fins which are stacked together for assembly into a heat exchanger. On passing this unit through the stacked fins the ring-shaped gaps are filled up with the filler material. The remaining thin film on the collars is also forced into the ring-shaped gaps when the tubes are subsequently expanded. A device for carrying out the process comprises a sleeve with a mandrel which slides inside the sleeve and forms a seal with the sleeve and a piston which likewise slides in the sleeve and forms a seal therewith and which lies ahead of the mandrel forming a space which can be varied in size and which accommodates the filler material. This device is positioned at and in line with a cylindrical space formed by the collars of the stack of fin material and the unit comprising the piston and mandrel with filler material between them is pushed out of the sleeve and through the cylindrical space formed by the stacked batch of fins.
