Title: Absorbent article having inflected barrier cuffs
Inventor: BENJAMIN JOYCE MARIE
IPC: A61F13/49
Filed: 1995-09-08
Abstract: Absorbent articles having side panels that provide inflected barrier cuffs which promote better containment and fit. The absorbent articles comprise a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core positioned between the topsheet and the backsheet; a side panel extending laterally from each longitudinal edge of the absorbent article and having a proximal edge, a distal edge and a fold intermediate the distal edge and the proximal edge; spacing means for spacing the distal edge away from the liquid-receiving surface (topsheet) of the absorbent article; and a closing means for securing the distal edges inboard of the proximal edges in the front waist region. The fold of the side panel is secured inboard of the proximal edges in the front waist region and is disposed outboard of the proximal edge in the rear waist region when fitted to the wearer. Thus, the side panels are inflected such that the portion of the side panels in the rear waist region provide a gasketing action about the buttocks of the wearer to contain exudates and a snug fit, while the stand-up portions of the side panels in the crotch region and the closed portion of the side panels in the front waist region provide channels to contain, restrain and hold body exudates.

Title: Method of correcting nonlinearities of an amplifier, and radio transmitter employing a method of this type
Inventor: SCHNABL GOTTFRIED
IPC: H04L27/36
Filed: 1997-03-21
Abstract: In order to correct nonlinearities of an amplifier (20) which receives a radio signal  (d')  and produces an amplified radio signal representing an input complex digital signal (m), a predistortion table, associating a value of a predistorted complex digital signal with each value of the input  complex  digital  signal,   is   stored,   and  the predistorted complex signal  (d) is modulated in order to obtain the radio signal addressed to the amplifier. In an adaptation period, a fraction (r') of the amplified radio signal  is demodulated in order to obtain a demodulated complex signal (r) which is compared with the input complex signal, with which the predistorted complex signal modulated in said adaptation period is associated, in order to update the predistortion table. The input complex signal or the predistorted complex signal has a phase which is constant modulo .pi. in the adaptation period.

Title: Digital vcr with trick play stream derivation
Inventor: MCLAREN DAVID LIONEL
IPC: H04N7/50
Filed: 1995-09-29
Abstract: A consumer digital video cassette recorder (210) may record an advanced television signal (09) having an MPEG like signal format. The predictive nature of the MPEG like signal format requires that additional I frame data be generated and recorded together with a normal play speed data stream (10) to facilitate non-standard speed, or trick play reproduction. Additional I frame data streams (121, 131, 141) are generated specifically for each replay speed and are written within recorded tracks to facilitate reproduction at the predetermined speeds. Various inventive methods for the derivation of full resolution and reduced resolution trick play data streams are disclosed. Inventive trick play data stream generation is disclosed for real time recording by consumer apparatus and non-real time normal and trick play data stream generation for use with pre-recorded digital media.

Title: Device for the surface treatment of hollow glass bodies
Inventor: HOFER WOLFGANG
IPC: C03C17/00
Filed: 1995-12-16
Abstract: The invention concerns a device for the surface treatment, in particular the final heat coating of hollow glass bodies, using a carrier gas enriched with coating materials. The device comprises a tunnel-shaped vaporisation hood with a conveyor belt which extends along the floor region of the hood and transports the hollow glass bodies, and with apertures along the sides and separated by spacer elements, these apertures being used for the alternate expulsion and drawing in of the carrier gas which flows around the hollow glass bodies and produces a metal oxide layer on the surfaces thereof. To prevent excessive heating of the spacer elements which would cause the coating materials to overheat and break down, and to prevent the build up of deposits and uneven speed distribution with the associated drawbacks, the intermediate elements are formed by tubular bodies which can be pressurized by a coolant stream (4).

Filed: 1997-07-10
Abstract: Installation for measuring the wheel offset of railway vehicles. It makes it possible to obtain three circumferential profiles of the zone of contact of the running tread of said wheels as the railway vehicles travel at low speed over the installation. Once the data have been processed by computer equipment, the offset and the shape error are detected in real time. The installation is made up of equipment, at the foot of the track, formed by a running support with its guard rail, wheel-position sensors, a system for picking up radial displacements and an electronic control system. This system transmits  the  data  to  computer  equipment  where  the process is carried out and the statistics generated and in which the results are displayed and stored. (Figure 1)

Title: Electric fumigation device
Inventor: GATZEMEYER JOHN J
IPC: A01M1/20
Filed: 1997-04-17
Abstract: An electrically activatable fumigating device and the method of its use. The device is adapted to be useable with vertically or horizontally oriented, wall-mounted electrical receptacles as well as receptacles mounted in horizontal countertops, all without the need for moving parts in the device. This is accomplished by the relative angle of the electrical plug to the longitudinal axis of a well contained within the body of the fumigating device from the mouth of which active ingredient is expelled by chemical reaction. Use of a modular heating assembly aids in allowing economical manufacture so that the fumigating device may be made inexpensively enough to be a single use device, with a self-disabling, single use, electrically activated heating means.

Title: Self-sealing framing system for buildings
Inventor: MAGOON ROBERT DEAN
IPC: E04B2/96
Filed: 1998-01-21
Abstract: A self-sealing framing system is disclosed for curtainwalls, storefronts, and other framing systems for buildings in which frame members are erected in a grid and infill panels set within the openings of the grid. An elastomeric weathering gasket is mounted to a first frame member such that a portion of the weathering gasket overlies a recess formed in a side wall of the frame member. In an undeformed condition the elastomeric weathering gasket normally extends through a plane defined by the side wall of the first frame member. A second frame member oriented substantially perpendicular to the first frame member has an end abutting the side wall of the first frame member. The end of the second frame member contacts the elastomeric weathering gasket and displaces it onto one side of the plane by the contact with the end of the second frame member. A portion of the weathering gasket is displaced into the recess in the side wall of the first frame member. The weathering gasket thus forms a continuous seal between the first and second frame members along the line of contact with the second frame member.

Abstract: A brake release tool incorporates a two-part structure wherein a portion accessible from outside the brake actuator does not move axially away from the brake actuator during caging. In this way, less room is necessary outwardly of the brake actuator housing than has been required in the prior art. An operator turns an outer bolt (38), which turns a threaded inner nut (42). The threaded inner nut moves axially to contact a piston, and moves the piston to cage the power spring. The bolt need not move axially outwardly. In further embodiments, structure is provided which is visible from outwardly of the brake chamber that provides an indication of when the brake is fully released. In one embodiment the structure is a pop-up indicator (120) that extends outwardly of the housing when it is at least partially caged. The indicator is pulled inwardly when the spring has been fully released. In a second embodiment, a dual threaded release bolt (142) is utilized. The bolt extends outwardly of the housing, then an indication is provided that the spring has not been fully released.
