Title: Velocimeter for a printing press web
Inventor: LINEBARGER RANDOLPH S
IPC: G01P3/36
Filed: 1988-12-21
Granted: 1993-09-07
Abstract: ABSTRACT OF THE DISCLOSURE           A velocimeter and a method for measuring the velocity of a printing press web are provided.  The velocity is measured without contacting the web by measuring a speckle pattern which is reflected off the moving web by a laser.  The reflected light is filtered and detected by a linear photodetector array which is differentially connected.  The photodetector array output is fed into a differential amplifier to obtain a differenced output which has a frequency that is related to the velocity of the web. The difference output is filtered through a variable filter set at a predetermined bandpass center frequency and bandwidth, and its frequency is counted to obtain the approximate velocity of the web.  Using the approximate velocity, a bandpass center frequency and bandwidth is selected which provides a substantially linear response of velocity at the counted frequency.  The variable filter is reset to the selected bandpass center frequency and bandpass, and the frequency of its output is obtained.  The web velocity is then determined using a predetermined relationship between web velocity and frequency for the selected filter setting.

Title: Process for brominating an alkylarene substrate
Inventor: TURNER PHILIP JAMES
IPC: C07C17/14
Filed: 1989-03-17
Granted: 1995-08-08
Abstract: Selective bromination of alkylarenes to the alpha monobrominated derivative is desirable as a precursor for the selective production of, for example, the corresponding alcohols.  The product can be obtained by a photolytic reaction between the substrate, hydrogen peroxide and hydrogen bromide in approximately equimolar ratios in an organic solvent, but improvement in the yield of the product coupled with similar or improved selectivity in its production was either not achieved or was actually impaired by a range of variations in the ratios and by omitting the solvent.  The invention employs mole ratios of H2O2:substrate of 0.1:1 to 0.4:1, preferably 0.2:1 to 0.33:1 and of H2O2:bromide of 1:1.2 to 1:2, preferably about 1:1.3 to 1:1.8 and progressive introduction of the H2O2, either in the presence or absence of the solvent, whilst irradiating with light preferably having principal emissions in the range of 250 to 600 nm, and the process thereby achieves either or both of improved yield and improved selectivity of the alpha monobrominated product.  The reaction mixture is preferably maintained at 50 to 70°C.  The process is especially suitable for deactivated alkylarenes, such as o-nitrotoluene.

Abstract: Abstract A  catheter  for  treating  a  constricted  blood vessel (10) comprises an elongated tubular body (3) having an internal lumen (4), a proximal portion and a  distal  portion,   and  includes  an  inflatable dilatation element (1) on the distal portion thereof. The dilatation element is in communication (9) with the  lumen  and  is  adapted  to  be  inflatable and deflatable  by  the  application  of  a  suitable therapeutic tissue dissolving fluid (13) pressurized within the lumen.  The dilatation element includes a wall (5) having microporus openings (12) adapted to be permeable  by  the  fluid  applied  to  inflate  the dilatation element.  The fluid, which is pumped into the interior space of the dilatation element, under sufficient pressure, presses through the microporus wall directly on and into the adjacent tissue (11). The  fluid  tends  to  dissolve  the  tissue,  thereby treatment time is considerably shortened and the long-term success of the treatment is improved, since the impairing  tissue  is  not  only  dislodged  but  also dissolved from the vessel.

Abstract: ABSTRACT An arrangement for associating an electrical device with a mounting is provided that includes cooperating structure to prevent the association of inappropriate electrical devices and mountings. Specifi-cally, cooperating support structures that are provided on the mounting and carried by the electrical device cooperate to provide the supporting of the electrical device within the mounting; the cooperating support structures being dimensioned so as to interfere with and prevent the association and support of an electrical device in a mounting that is inappropriate therefor, In a specific arrangement, either the electrical device or the mounting carries receiving structure with defined openings, and the other of the electrical device or mounting carries interfitting protuberances. The appropriate dimensions of the protuberances and the openings prevent the association of inappropriate combinations of elec-trical devices and mountings while permitting the association of appropriate combinations of electrical devices and mountings. Each of the protuberances has different predetermined dimensions and the appro-priate openings include corresponding dimensions. For example, in a specific configuration, a member or fitting attached to an electrical device includes a right-hand side protuberance that is larger than the left-hand side protuberance, and the appropriate mounting includes correspondingly disposed and dimensioned openings; i.e., the right-hand side opening being larger than the left-hand side opening. In this manner, different supports can be formed for two different electrical devices from identical stampings by bending of the stampings in opposite directions.

Granted: 1992-05-19
Abstract: ABSTRACT OF DISCLOSURE    A counterbalancing assembly for use with a gate vertically rotatable about an axle carried by a support structure.  The counterbalancing assembly utilizes a coil spring having one end attached to the support structure and having its other end attached to one end of a cable.  The other end of the cable is attached to the gate at a point spaced apart from the axle.  This cable, intermediate its ends, is trained around a pulley. The pulley is positioned so that as the gate is lifted, the spring provides a resilient force assisting in the opening of the gate and, as the center of gravity of the gate crosses over the axle and the gate starts to fall on the other side of the axle, the spring provides a force counteracting this falling movement.         With this arrangement, the coil spring also assists in closing the gate from the open position.
