Abstract: A composite strip for preparation of a substrate edge for application of labels is disclosed. The composite strip comprises an elongated carrier web having an upper surface and a lower surface with the lower surface having a pressure sensitive adhesive backing covered with a removable release sheet. A high tensile strength film, such as that sold under the trademark "Mylar" by DuPont, is directly bonded to the upper surface of the carrier web by a further adhesive. This film provides a receptor surface for receiving labels. The film is of a width equal to or less than the width of the carrier web and of a width to receive a label therein. This composite strip has proven useful in preparing a substrate, such as an existing file folder tab or the edge of an x-ray jacket for the subsequent application of a discrete series of labels applied about the edge of the substrate. Such discrete series of labels may also be applied to the composite strip before its application to the edge of the substrate. The composite strip is also advantageously used in combination with a tab extension to provide an add-on tab assembly.

Abstract: A steel strip is continuously annealed while successively travelling through a heating, soaking, primary cooling, overaging and secondary cooling zone in an annealing furnace. In the overaging zone, an endless steel strip is allowed to run through a passageway that extends spirally from the entry end of the averaging zone to the point where overaging is completed, at a given distance in the direction of radius. The guide strip travels at the same speed as the steel strip being processed that is delivered from the primary cooling zone. On the entry side of the overaging zone. the strip being processed is laid over the guide strip so that the two strips spirally travel through the overaging zone side by side. The processed and guide strips running together are shifted out of the spiral passageway atthe point where overaging is completed. Then, the processed strip is separated from the guide strip by shifting at least one of the two strips. While the separated processed strip is delivered to the subsequent secondary cooling zone, the guide strip is returned to the entry end of the overaging zone for the next trip through the spiral passageway. Helical devices are used for changing the position and running direction of the strip being processed and the guide strip. The overaging furnace is annular in shape and provided with a number of radially disposed guide rolls on the inside. Each guide roll has a plurality of guide grooves in which both edges of the guide strip are fitted.

Abstract: A keyless entry system can lock and unlock an automotive vehicle door, a trunk lid, a glove box and/or a steering column without an ignition key. The system comprises a transmitter (100) producing a radio signal indicative of a preset unique code, and a controller (200) receiving the radio signal and performing desired locking or unlocking operation when the code from the transmitter (100) matches a preset code. A manual switch (210) is provided to order the transmitter (100) to transmit the code-indicative radio signal to the controller (200). The transmitter (100) encloses a battery acting as a power source. Locking the transmitter in the vehicle is detected by detecting that the code signal level remains substantially unchanged for a given period of time after the vehicle is locked. In such cases, an alarm is produced to remind the driver to remove the transmitter (100) from the vehicle cabin by operating the manual switch to open the door. An optional feature disables the keyless entry system if the driver fails the retrieve the transmitter (100) after the alarm.

Abstract: A monolithic multi-layer capacitor is disclosed having a central capacitively active area and two electrode joining sections separated from the active area by sloped sections. The dielectric layers are about 1 micron thick in the active area and taper gradually to zero thickness in the sloped sections. Electrode layers in the active area have a thickness in the range from 200 to 500 Angstroms and sufficient thickness throughout the sloped sections for adequate current carrying capacity. Various acrylates are used for the dielectric layers, the number of layers ranging from a few to many thousands. 
     Apparatus and methods are disclosed for the fabrication of such capacitors on a high speed, production scale basis. Such employ techniques for the flash evaporation of highly reactive monomers of acrylate dielectric materials so as to form a gaseous stream of such materials. The gas stream is controllably directed to a deposition surface for condensation and subsequent curing by a field enhanced gas discharge electron beam source. The control of the dielectric gas stream is accomplished by means of adjacent gas streams of an inert gas directed to areas of the deposition surface where deposition of the electrode material is unwanted. Means are disclosed for the atomization of the monomers of the dielectric material in preparation for its flash evaporation.

Abstract: An ink jet printer includes a print head (10) for producing at least one jet drop stream (12) from a fluid filament emerging therefrom, and a charge electrode arrangement (26, 28) for inducing electrical changes on drops formed from the fluid filament. The charge electrode arrangement is movable into and out of an operating position in which it is adjacent and at least partially surrounds the fluid filament. A deflection field is established prior to start-up in which the field has a non-zero electrical potential in the region of the fluid filament. At start-up and shutdown of the printer, the charge electrode arrangement (26, 28) is retracted from its normal operating position (as shown in Figure 1b) and drops are charged by the deflection field. As a consequence, the charge electrodes (28) are not contaminated by ink from the unstable jets. The drops in the jet drop streams are, however, charged and deflected to a catcher (33) by the deflection field. After stable operation is obtained, the charge electrode arrangement is moved into its normal operating position (as shown in Figure 1d). At shutdown of the printer, this sequence of steps is reversed.
