Title: Method and apparatus for processing printed products
Inventor: HAENSCH EGON
IPC: B65H9/00
Filed: 1992-05-15
Abstract: ABSTRACT          In the processing of printed products, such as news-papers, magazines or parts thereof, the printed products (24) are transported, held at a first edge (26), running transversely to its conveying direction (F), by the mouth (22) of individually controllable grippers (14) of a conveying device (10) moved at a conveying speed (v1).  The products are displaced in the mouth (22) and with at least partial opening of the grippers (14), are brought to rest with the second edge (30) opposite the first edge (26) on straightening means (39) driven approximately in the conveying direction (F), and transported further upon subsequent closure of the grippers (14).  For positioning in the gripper (14), the printed products (24) are thrust towards the interior of the mouth (22) of the grippers (14) by the straightening means (39).          The latter are driven relative to the conveying speed (v1) at a lower speed (v2) in the case of the second edge (30) leading in relation to the first edge (26) and at a higher speed (v2) in the case of a trailing second edge (30), before the grippers (14) are closed.

Abstract: ABSTRACT OF THE DISCLOSURE          A T-bar partition support clip for securing a rectangular channel shaped partition track to a T-bar ceiling support includes first and second spaced, parallel, vertical leg portions formed from a deformable sheet metal material.  Upper ends of the first and second vertical leg portions are perpendicularly connected to coplanar first and second horizontal leg portions.  The first and second horizontal leg portions are connected by a vertically extending clip portion possessing vertical sidewalls connected by a top web.  A pair of juxtaposed inwardly extending protuberances are formed by punch indentations in central regions of the vertical sidewalls.  The vertical sidewalls converge inwardly and downwardly from a maximum lateral separation adjacent the web to a minimum lateral separation adjacent junctions of the vertical sidewalls with the first and second horizontal leg portions.  In use the clip portion is inserted over a top ridge of a T-bar ceiling support with the protuberances in engagement with a reduced neck portion of the T-bar ceiling support.

Title: Controlled clean-emission biomass gasification heating system/method
Inventor: BENDER ROBERT J
IPC: F23G7/10
Filed: 1993-09-29
Abstract: A biomass fuel gasification chamber, blast tube, and heat exchange chamber are interconnected horizontally and subjected to negative drawing pressure by a large variable speed chimney fan. An auger with an air lock feeds biomass fuel automatically into the gasification chamber. Fuel is moved across the gasification chamber on a partially serrated sloping grate. Three stages of fuel activity are created: anaerobic heating for pyrolysis, combustion, and incandescent charcoal oxydation for gasification. A variable speed fan, variable flue, and directional air duct and baffles control the stages with underfire air. A programmed auger in an airtight chamber removes ash automatically. In large systems a hydraulic moving wedge floor assists the fuel feeding auger and a moving sloping grate moves the fuel. A fan and long preheating duct with baffles and fins inside the gasification chamber preheat and direct air into a blast tube leading from the gasification chamber. Openings from the preheating tube angled both longitudinally and transversely into the blast tube create turbulence in the blast tube directed away from the gasification chamber. Preheated directed air flow and the negative pressure of the chimney fan draw gases from the gasification chamber into the blast tube, crack the gases, and shoot a fire blast into the heat exchange chamber. The fire blast heats an external system. Particulates are removed producing a clean-emission exhaust gas. Temperature and air quality sensors in the chimney provide feedback signals to various system controls to maintain optimum operating conditions.

Title: Ethernet repeater
Inventor: ADAMS MARTIN C
IPC: H04L25/49
Filed: 1993-10-29
Abstract: ABSTRACT           An adaptation circuit for operation in conjunction with a repeater element for a data network is disclosed.  The repeater element is of a type capable of communicating with one or more other repeater elements via an 'inter-repeater bus' such that they together operate as a single logical repeater.  The adaptation circuit is arranged to receive a plurality of two-level signals from said repeater element, to provide electrical connection to the inter-repeater bus, and to convert said two-level signals into a number, smaller than said plurality, of multi-level signals.  This results in the electrical bus between the elements, which is also a feature of the invention, requiring a reduced number of conductors.  The adaptation circuits may be connected with repeater elements to form a logical repeater, which preferably operates as an ethernet repeater.
