Title: Method and circuitry for determining symbol timing for time division multiple access radio systems
Inventor: ARNOLD HAMILTON W
IPC: H04L7/02
Filed: 1989-04-12
Granted: 1993-01-05
Abstract: ABSTRACT OF THE DISCLOSURE In order to correctly demodulate a received sequential burst of symbols in a Time Division Multiple Access (TDMA) radio system, proper symbol timing is necessary. A method and circuitry for estimating symbol timing is disclosed in which the IF radio signal is sampled and digitized at a sampling rate which is sixteen times the symbol rate. The digitized samples are processed to obtain phase values. A one symbol delay is introduced and differential phase values derived, a differential phase value being derived for each of the sixteen sampling times per symbol. The differential phase values are compared with expected differential phase values and the absolute differences are accumulated for each sampling time over substantially the entire burst. The symbol timing is selected to be the particular one-of-the-sixteen sampling times that results in the minimum sum of differences.

Abstract: Abstract of the Disclosure A local area network for interconnecting terminals and other users and data processing systems and other service providers over a communications link.  The users and providers connect to the communications link by means of interface units each of which may connect to several users or providers.  The interface units communicate over the communications link by means of messages.  When a user requires the use of a service, the interface unit establishes a virtual circuit between it and the interface unit connected to the service provider and a service session which allows the user and the service provider to communicate over the virtual circuit.  If several users connected to the one interface unit as the first user require services provided by provides which connected to the same interface unit as the first provider  they communicate in sessions over the same virtual circuits.  The session messages are accumulated into single virtual circuit messages that are acknowledged in unison by the receiving interface unit.          Each virtual circuit in the users  interface units includes a timer which reset when a message is transmitted over the virtual circuit and a data waiting flag set whenever data is present to be transitted over the virtual circuit.  The interface units are inhibited from transmitting over a virtual circuit unless the timer has timed out and the data waiting flag is set.

Abstract: Abstract of the Invention A dielectric block filter which may be mounted on a printed circuit board or other substrate as a single component is disclosed.  The dielectric filter utilizes metallized hole foreshortened resonators  in the dielectric block, which employs capacitive coupling between resonators controlled in part by an electrode strip coupled to the conductive material covering the majority of the dielectric block surface.   Input and output coupling is accomplished via terminals asymmetrically arranged in a mounting bracket.  Mounting tabs on the bracket opposite a recessed area holding the dielectric block secure the filter to the circuit board and provide ground connection for the filter.  Two or more filters may be arranged on the circuit board to form a duplexer.

Abstract: LOW TEMPERATURE EXTRUSION PROCESS       FOR QUICK COOKING PASTA PRODUCTS            Abstract of the Invention Quick cooking pasta products are extruded in a low temperature process by advancing a par-tially pre-cooked mixture of pasta flour and water prepared in a preconditioner along the length of a screw extruder through a cooking zone, then through a venting zone and a forming zone, and finally through an extrusion die to yield an extruded prod-uct.  The mixture has a maximum temperature of 215° F. in the cooking zone in order to substantially eliminate the formation of darkened specks in the final extruded product which would otherwise repre-sent portions of the mixture that are burned during cooking.   Limiting the maximum temperature of the mixture in the extruder also greatly enhances the extruded pasta quality by increasing product resis-tance to overcooking and improving the retention characteristics of the original product integrity. Venting of the gaseous products from the mixture during the time that the latter passes between the cooking zone and the forming zones removes signi-ficant amounts of moisture to enable less shear to be imposed on the mixture during the cooking process and to decrease the time required for rehydration of the extruded products.   A venting device has a rotatable screw for enabling gaseous materials to be discharged  from  the  mixture  while  substantially preventing the escape of the mixture from the ex-truder barrel.

Abstract: An expansion dowel assembly includes an expansion sleeve, an expanding member and a bolt for pulling the expanding member into the expansion sleeve. The expansion sleeve has a leading end and a trailing end with a bore extending between its two ends. At the leading end, the bore is conically shaped and converges toward the trailing end. From the trailing end of the conically shaped section, the bore is cylindrically shaped and extends toward the trailing end to another smaller diameter cylindrically shaped section of the bore. At the transition between the two cylindrically shaped sections there is a stop shoulder which limits the pulling-in action of the expanding member and the radial widening of the expansion sleeve.
