Abstract: A multi-layer laminate structure from which containers are injection blow moldable, includes a layer of scrap (111) composed of the other thermoplastic resins used in making the laminate structure, which comprises outer and inner polyolefin layers (103, 105) an intermediate oxygen barrier layer (107), preferably ethylene-vinyl alcohol copolymer, and adhesive layers (109, 113) bonding the barrier layer to the inner layer (105) and the scrap layer (111) which is interiorly of the outer polyolefin layer. 
     Apparatus (1) for producing parisons having such a structure has a sequence of extruder elements (3,4, 5) which discharge polymeric materials in turn into a common duct (42) to form a laminate composed of a plurality of thin polymeric layers, said duct conveying the laminate to a principal delivery channel (40) for joining with a relatively thick polymeric layer flowing in the principal delivery channel (40) from another extruder element (7) upstream of the said elements (3,4,5); the resulting structure thereafter issues as a parison from a nozzle (23) of the apparatus (1).

Abstract: Method in which a free exchange line can be seized from each extension and transferred if required through suffix dialling to another extension on the PBX system. The PBX system is microprocessor- controlled and the object is to find a suitable method for carrying out the aforementioned switching processes, particularly using MF dialling. To achieve this, an MFD receiving circuit is connected to the output of each extension and transfers MFD information in processible form to the microprocessor, which can then control the switching processes as appropriate. The method is suitable for use in small PBX systems. <IMAGE>

Title: High surface area filter cartridge
Inventor: TANG YUAN-MING C O MINNESOTA M
IPC: B01D29/01
Filed: 1988-08-08
Abstract: New, high surface area per unit volume, generally cylindrical filter cartridges for gaseous or liquid filter applications are described. These filter cartridges which comprise a nested arrangement of substantially disk shaped layers having a radial pleat pattern embossed therein, are capable of achieving higher surface areas per unit volume than can be achieved with conventionally pleated filter cartridges. Utilization of the filter media is extremely high as blocking of adjacent layers of filter media is avoided and fluids are evenly distributed over the total area of the filter media as a result of the series of channels created by the nesting of the disk shaped pleated layers.

Inventor: JOHANNSEN FRED DIPL-ING
IPC: B41J2/045
Filed: 1989-01-07
Abstract: Both for the print image and also for reliability when printing with ink jet mosaic printers, it is important that the expulsion of ink droplets out of the individual outlet nozzles occurs at the same constant speed. Since, in addition to the driving criteria, material properties and production influences also play a not inconsiderable role in this, in the known devices for expulsion of droplets an adjustment is performed. This adjustment is achieved for example by setting the pulse voltage with which the individual drive elements of an ink jet mosaic head are operated. In this case, no simple setting is provided by means of which it is ensured that the ink droplets emerge from the outlet openings 2 in phase. This is achieved according to the invention in that the sections (17, 18), serving as pressure channels, of the ink channels (3) from the pressure chambers (4) as far as the outlet openings (2) and the suction channels (21, 22) leading into the pressure chambers (4) are all constructed with identical length. Due to the fact that the ink droplets emerge from the outlet openings (2) in phase, graphic representations are possible with a fine matrix and a compact design of the print head. <IMAGE>

Abstract: A packet switching system has at least first and second packet level control devices (10₁, 10₂) and first and second frame level control devices (20₁, 20₂). When a data packet (DT) is received at the first frame level control device via a communication line which is connected thereto, the first frame level control device disassembles the data packet and transfers only a header portion (PH) of the data packet to the first packet level control device, thereby a data portion (UD) of the data packet being transferred directly to the second frame level control device. The second frame level control device assembles the data portion received from the first frame level control device and the corresponding header portion received via the first and second packet level control devices, and transmits the assembled data packet on a communication line which is connected to the second frame level control device.

Abstract: The invention relates to a method and circuitry for auto­matic control of the frequency of a radio telephone, ac­cording to the counter principle and on the basis of the reception frequency, in which case the reception frequency (fin) is mixed with the output frequency of a phase-locked loop (7) in a first mixer (1), the output frequency (if1) of the first mixer (1) is mixed in a second mixer (2) with the frequency derived from a local oscillator (5), and the frequency of the phase-locked loop (7) is controlled on the basis of the frequency deviation of the output frequency (if2) of the second mixer (2). Whereas in prior-art cir­cuitries at least two oscillators are needed, one of which must additionally be very precise, in the present invention one local oscillator (5) suffices, which is an oscillator having a controllable frequency and is controlled on the basis of the said frequency deviation, the reference fre­quency (fr) of the phase-locked loop (7) being derived from the frequency (f) of the local oscillator (5). The frequen­cy deviation of the second mixer (2) can be determined, for example, by counting pulses within a certain time interval, the time interval being determined by counting a certain number of pulses of the local oscillator (5).

Abstract: A vehicle identification camera arrangement (10, 42) for photographing a vehicle identification number (VIN) plate through a vehicle windshield includes a housing having an object window (58) at its distal end forwardly of the lens (22) and an aperture stop adjoining the lens with the length of housing from the lens establishing the distance to the windshield. The aperture stop suffi­ciently reduces the aperture to increase the depth of field to encompass the variations in distance of the VIN plate behind the vehicle windshield. Preferably, the arrangement is provided as an adapter housing (42) whose interior is divided into an upper lightbox section (60) and a lower exposure section (62) by an opaque baffle (64) and a dif­fusing screen (66). The lightbox section (60) receives flash illumination and directs it at a sharp angle with respect to the optical axis of the camera objective to illuminate the VIN plate through the windshield with a minimum of reflection from the windshield along the camera exposure axis. Optionally, the housing includes an arrangement for mounting an information label adjacent the object window to provide for the production of composite VIN plate and information image exposures.

Abstract: If such a control rod has in its lower area facing the reactor core an Ag-In-Cd absorber (5) and in its upper area a B4C-absorber (6), there is the risk that fragments of the B4C absorber can pass into the gap between the Ag-In-Cd absorber (5) and the cladding tube (2). Swelling of these B4C absorber fragments could then lead to damage of the cladding tube (2). To avoid such damage, it is provided that the Ag-In-Cd absorber (5) is separated from the B4C absorber (6) by an intermediate plug (7) which is rigidly connected to the cladding tube (2) and that between the intermediate plug (7) and the Ag-In-Cd absorber (5) a cavity (8) is provided. To avoid local power excess in fuel assemblies having such control assemblies, it is provided that the cavities of adjacently arranged control rods are offset with respect to one another, seen in the axial direction and that the control rods of a control assembly are inserted in symmetrical core positions with identical position of the cavities. <IMAGE>
