Abstract: A contact toaster has a housing (10) with a product inlet, product outlet and at least one toasting chamber (20) defined in the housing. A heated platen (19) is mounted in the housing and has a platen surface arranged for toasting the food products. A flexible endless belt (22), which when rotated, is arranged to pass the food products in a toasting path along the platen (19) between the belt (22) and the platen (19). An infinite controller (40) acts to selectively displace the belt to adjust the distance between the belt and the platen to any value between minimum and maximum distance limits to accommodate food products of different widths. A guide (21) is situated between the belt (22) and the infinite controller (40) so that the controller is in contact with at least one area of the guide. The infinite controller (40) includes a variable distance element (41A-41D) with a cam surface which is sellable to any selected point of the cam surface between minimum and maximum cam radial limits to move the guide and belt to any belt to a selected platen distance that can have any value equal to or intermediate the maximum and minimum distance limits.</SDO AB>

Title: Synchronous spread-spectrum communications system and method
Inventor: SCHILLING DONALD L
IPC: H04B1/69
Filed: 1991-12-10
Granted: 2001-11-27
Abstract: A spread spectrum communications system for use over a communication channel, including a transmitter-generic-chip-code generator (101), a transmitter-message-chip-code generator (102), an EXCLUSIVE-OR gate(103), a combiner (104), a transmitter (107), a receiver-generic-chip-code generator (121), a receiver-generic mixer (123), a generic-bandpass filter (125), a receiver-message-chip-code generator (122), a receiver-message mixer (124), a message-bandpass filter (126), and a synchronous detector (139). The transmitter-generic-chip-code generator (101) generates a generic-chip-code signal and the transmitter-message-chip-code generator (102) generates a message-chip-code signal. The EXCLUSIVE-OR gate (103) spread-spectrum process message data with the message-chip-code signal to generate a spread-spectrum signal. The transmitter (107) transmits the combined generic-chip-code signal and spread-spectrum signal, on a carrier signal (108) over the communications channel as a spread-spectrum-communications signal. The receiver-generic-chip-code generator (121) generates a replica of the generic-chip-code signal. The generic mixer (123) recovers the carrier signal from the spread-spectrum-communications signal. The receiver-message-chip-code generator (122) generates a replica of the message-chip-code signal. The receiver-message mixer (124) despreads the spread-spectrum-communications signal as a modulated-data signal. The tracking and acquisition circuit (121) uses the recovered carrier signal for synchronizing the replicas of the generic-chip-code signal to the recovered carrier signal. The synchronous detector (139) synchronously demodulates the modulated-data signal as received data.

Granted: 2005-04-26
Abstract: The static mixer contains precision cast elements (1) which are arranged along a central axis (10) and which in each case have a reinforcement region (4) at their circumference which extends over the entire circumference. These cast elements (1) are assembled with intermediate elements (2) to form a cylindrical body. Joint locations between the elements (1, 2) form surfaces (40a, 40b, 20a, 20b) which stand transversely to the central axis. For each isolated cast element, in a rotation about its central axis the joint locations are accessible to machining tools for a subsequent machining - in particular for a grinding or turning. As a result of the subsequent machining a predetermined total length (L) of the mixer in the direction of the central axis can be precisely achieved.

Abstract: An athletic pole including a handle, a shaft, and a handle-to-shaft transition assembly, said transition assembly adapted for allowing the handle to articulate. The transition assembly includes an enlarged shaft base on the shaft, the shaft base including a handle-base-engaging surface. The transition assembly also includes an enlarged handle base on the handle. The handle base and the shaft base are biased together by a tension force into a mating, coaxially aligned position when any bending forces applied to the pole are insufficient to overcome the tension force, the handle being pivotable to an articulated position relative to the shaft upon the application of a predetermined bending force on the pole sufficient to overcome the tension force. During handle articulation, the enlarged dimensions of the handle base and the shaft base allow the periphery of the handle base to travel across and engage the handle-base-engaging surface of the shaft base such that, after an initial range of handle articulation, the bending force necessary to continue articulation or to maintain the handle in a desired articulated position is reduced relative to the bending force that would prevail if the periphery of the handle base were not allowed to travel across the handle-base-engaging surface toward the center of the shaft base.

Abstract: Disclosed is a temperature compensated long period optical fiber grating filter. The long period optical fiber grating filter includes a core formed with a long period grating, a cladding surrounding the core, a coating coated over a portion of the cladding not surrounding the long period grating, and a re-coating coated over a portion of the cladding surrounding the long period and made of a material exhibiting an increase in refractive index in accordance with an increase in temperature, the recoating serving to allow a coupling wavelength shift caused by the increase in refractive index to be carried out in a direction opposite to that of a coupling wavelength shift caused by a refractive index difference between the core and the cladding. In accordance with this long period optical fiber grating filter, a temperature compensation can be more easily achieved without any inconvenience caused by an adjustment of refractive index in the filter or an addition of a material for avoiding a variation in refractive index depending on temperature.
