Abstract: A digital transmitter-receiver unit for a radio communication system is described. The transmission path of the unit includes a modulator 11 adapted to modulate received transmission data in accordance with an automatic frequency control signal, a frequency synthesizer 12 adapted to synthesize the modulated data with a reference signal to provide a locally oscillating signal and a primary mixer 16 adapted to receive the locally oscillating signal and output a transmitting carrier signal. The receiving path includes a secondary mixer 17 adapted to synthesize an incoming signal with the locally oscillating signal, a bandpass filter 18, a demodulator 20 adapted to demodulate the synthesized signal, a lowpass filter 21 and a distortion automatic frequency control circuit 22 for generating the said automatic frequency control signal from the demodulated signal in response to a given external control signal. A wideband automatic frequency control circuit 23 is arranged between the distortion automatic frequency control circuit and the modulator and adapted to determine whether or not the automatic frequency control signal emerging from the distortion automatic frequency control circuit has a frequency within an automatic frequency control range and to perform a wideband frequency tracing function if not.

Title: Fluid flow fitting and flow control device
Inventor: DARLING BRIAN JAMES
IPC: F15B11/05
Filed: 1998-04-24
Abstract: A fitting for a fluid flow control device comprises a body portion (137) having an axial through bore (144). A tubular portion (162) of the body portion (137) of the fitting makes a close sliding fit with a surface (68) of a housing bore. A first portion (150) of the through bore (144) opens from the tubular portion into a second pressure chamber (30) of the housing. A second portion (152) of the through bore fluidly connects with a side bore (56). A third portion (154) of the through bore opens into an outlet flow passage (42) for the flow of fluid out of the fitting and the control device. An inlet bore (170) of the fitting aligns with the wet flow passage 32 of the housing at the outer surface (166) of the tubular portion and opens into the first portion. A passage (60) fluidly connects the side bore (56) with a first pressure chamber (28) of the device. Improved fluid flow through the control device reduces risk of noise generation.

Title: Arrangement for transmitting packet data segments from a media access controller across multiple physical links
Inventor: MERCHANT SHASHANK C
IPC: H04L12/56
Filed: 1998-06-25
Abstract: A Gigabit network node (12) having a media access controller (16) outputting packet data at Gigabit rates uses multiple 100 MB/s media interface links (21) coupled to a physical interface (20) to enable implementation of a Gigabit network using low cost data links (22). A modified reconciliation layer (18), also referred to as a media interface, receives a data packet from a Gigabit MAC (16) and divides the received data packet into multiple data segments having a prescribed length. The multiple segments are output on the multiple media interface links (21) according to a prescribed output protocol, enabling a corresponding media interface at the destination station to recompile the data packet from the received segments from the multiple transmission paths (22). The transmission of the segments upon multiple transmission paths (22) provides an efficient load balancing of data traffic among the multiple transmission paths.

Abstract: A method of reinforcing a selected portion of a structural part 24 utilises a flexible member 20, eg a tube, at least a portion of which is covered with an expandable resin 22, eg a thermally expandable resin. The flexible member 20 is inserted into a cavity 26 in the part 24 and is bent prior to or during the inserting step so that it conforms to the geometry of the part 24 to be reinforced. After securing the flexible member 20 in place, the resin 22 is expanded to bond it to the selected portion of the part 24. The part 24 may be a roll bar, an A-pillar joint or a seat frame for a vehicle.

Title: Photographic elements with antistatic layers
Inventor: NAIR MRIDULA
IPC: G03C1/00
Filed: 1998-08-21
Abstract: A photographic element comprising a film support, having on one side, at least one light-sensitive layer and other side, an aqueous coated layer having a film forming binder content of greater than 70 volume percent, and being at least 1.0 micron thick an antistatic layer which contains more than 30 volume percent of non-film forming particulate conductive material, and an upper aqueous coated layer with at least 70% by volume of binder. There may be a layer coated over the upper layer which comprises an aqueous coated transparent magnetic recording layer. The layers may be simultaneously applied to the support. The placing of the antistatic layer between two aqueous coated adjacent layers, which preferably comprise a magnetic recording layer and a curl control layer or two curl control layers, results in excellent adhesion of the coated layers to the support compared to where the antistatic layer is closest to the support.

Title: pressure plate having a manually operable wear take-up device
Inventor: KRAUS GEORG
IPC: F16D13/75
Filed: 1998-09-08
Abstract: A clutch pressure plate assembly 12 has a wear compensating device 30 comprising relatively rotatable rings 32, 34, with inclined adjusting surfaces, that are held in position by lever 60 which is connected to a bolt member 50 of a manually operable wear take-up device. When the clutch is disengaged a tool 80 is inserted, around the bolt member 50, in spacing d and the clutch is again engaged, this results in the bolt member 50 being displaced relative to pressure plate 36 and a frictional clamped fit, between bolt member 50 and throughhole 52, is released. At the time of this relative displacement, the lever 60 lifts from ring member 32 moving the pressure plate 36 in the direction of flywheel 14, thereby taking up wear. After carrying out the wear compensation with respect to housing 16, the bolt member 50, because of its relative displacement, is in a position corresponding to that before wear occurred so that the same tool 80 may be used repeatedly for wear compensation. In another embodiment a screw bolt which is threaded into a threaded opening in the pressure plate 36 may be used.

Title: Welding control
Inventor: HONG SUNG JIN
IPC: B23K9/12
Filed: 1998-12-17
Abstract: A robot welding apparatus responds to the temperature of a workpiece (35) by changing the welding conditions. If, for example, the temperature of the workpiece (35) exceeds a threshold value, the welding voltage and current are reduced. Also, the relative speed of the welding torch (7a, 7b) and the workpiece (35) may be increased in response to an increase in the temperature of the work piece. Alternatively the welding conditions may be changed at a certain point along the welding line.
