Abstract: A damper seal (10) and method of sealing and damping a rotating shaft (12) is provided with a stator housing (14) and at least two sealing blades, an upstream sealing blade (16) and a downstream sealing blade (18). There are at least two partitioning walls (20) disposed between the sealing blades (16,18) and attached to the stator housing (14). The clearance between the downstream sealing blade (18) and the shaft (12) is greater than the clearance between the upstream sealing blade (16) and the shaft (12). The damper seal (10) restricts the flow of fluid from regions along the shaft that are at different pressures and damps vibratory or whirl motion of the shaft.

Abstract: The invention relates to a magazine arrangement for enabling one or more printed circuit boards to be held in the magazine but readily removable therefrom, wherein the circuit boards are disposed side-by-side and can be inserted into and withdrawn from the magazine by virtue of each board having upper and lower edge-parts which coact with upper and lower grooves in the magazine. Each board carries on its edge that faces inwardly of the magazine one part of a connecting element which is intended to be brought into and out of coaction with a second part of the connecting element, this latter part being located on the backplane of the magazine. The two parts of the connecting element are each provided with a corresponding connecting device, wherein devices are provided for damping transient voltages that occur within board-mounted and/or board-connected electrical and/or electronic components, among other things, when a normalized voltage is applied to said components.

Abstract: Coin-controlled apparatus for locking shopping carts together in nested series at a cart parking station having coin-controlled mechanism mounted on a cart, e.g. on the handle of the cart, which is adapted for receiving and releasably locking therein a latch bar on a tether which is attached to the next cart in the nested series. Deposit of a coin is required to release the latch bar to free the cart for being wheeled away by the user. The coin is held until the user brings the cart back to a cart parking station, nests it in the end cart at the parking station, and inserts the latch bar which is tethered to the end cart in the mechanism to lock the returned cart to the series and to provide for return of the user's coin. The apparatus has a detent arrangement permitting reduction in its size.

Abstract: A cantileverable roll for use in a roll press, wherein the cantileverable roll cooperates with a backing roll. The cantileverable roll has a rotating surface and is either a solid rotatable roll body or a stationary roll body with a rotatable shell around it. A journal at each end of the cantileverable roll is supported in a respective bearing bracket. At one end of the roll, preferably the drive end, there is a non-rotating extension piece which extends out axially from the roll body and is fastened to the bearing bracket at that end. A tension bar or the like connects the extension piece to a stationary structural part and introduces force in the roll body which compensates for the weight of the roll when the other end of the roll is temporarily unsupported and the roll is cantilevered. The backing roll may also be cantilevered. The various techniques for supporting the one end of the roll by using the coupling element from the extension piece to the frame of the paper making machine are disclosed.

Abstract: New chemical compounds, bis(pyrrol-2-yl)halocarbylmethanes, also known as meso-halocarbyl dipyrromethanes, are made by recting pyrrole in either of two reaction schemes. Once such scheme converts pyrrole through an intermediate, a halocarbyl carbonyl pyrrole, to a [2-(1-hydroxyl-1-hydro-1-halocarbyl)pyrrole], and then converts the latter to the desired halocarbyldipyrromethane; the last step in this scheme is a novel and useful method in itself. The other such sequence converts pyrrole, by reaction with a halocarbyl aldehyde, directly to the desired halocarbyl dipyrromethane.

Abstract: A method of and system for paging mobile stations within a cellular telecommunication system wherein the allocation of control channel paging capacity is optimized. Each page request for a mobile station received by the system is classified into a predesignated group based upon the characteristics of the request, such as the degree of certainty with which the location of the mobile is known and the origin of the page request. In accordance with the predesignated group to which the page request is assigned, each page request is assigned a paging extent designation to be associated with one or more page attempts and representing the geographic area within the system to which each page attempt is to be broadcast. A paging priority is then assigned to each page attempt based upon the previously assigned group characteristics and paging patterns. Each page attempt is executed within the system according to its designated priority.

Abstract: A multifunctional visceral catheter having a self-guiding system in the form of a pair of fiberoptic sensor systems which are sensitive to a predetermined analyte, the analyte being one which is removed from the vascular circuit of interest to a high degree, such as galactose in the hepatic venous system or creatinine in the renal venous system. One of the sensors is disposed on the catheter so as to be positioned within the venous system of interest, while the other sensor remains outside the venous system in the vena cava. A substantial difference between analyte concentration values as measured via the two fiberoptic sensor systems provides immediate confirmation that the catheter is properly positioned. In addition to being self-guiding, the catheter provides for direct sampling of venous blood; includes a fiberoptic system for continuously monitoring oxygen saturation in the hepatic or renal venous blood; and is capable of measuring absolute hepatic or renal blood flow.

Abstract: A lock assembly includes a retaining block having a substantially rectangular recess with a shoulder defining a transition between a wider outer portion and a narrow or inner portion. A door knob shaft having a rectangular cross-section extends through the inner portion of the recess in the retaining block for extending and retracting a striker. A substantially rectangular locking bar engageable with the recess has a shape which corresponds with the recess. The locking bar has a slot at one end for engaging and capturing the door knob shaft to prevent its rotation. When the orientation of the locking bar is reversed, the locking bar rests on the shoulder of the recess and does not engage the door knob shaft.
