IPC: E06B3/263
Filed: 1994-07-19
Abstract: An insulating composite frame member is disclosed which comprises an elongated gutter member and an elongated face member disposed in parallel, spaced apart relation. First and second facing flanges project toward one another from the gutter member and the face member respectively. A thermal isolator comprised of a thermally insulating material has first and second jaw-like clamps formed on opposite sides thereof which engage the first and second facing flanges respectively to secure the gutter member and the face member to the isolator. The frame member further includes means formed on the gutter member and the face member for crimping against the clamps of the isolator to lock the isolator to the gutter member and the face member. In the disclosed embodiment the isolator is adhesively bonded to the gutter member and to the frame member in addition to the mechanical coupling provided by the jaw-like clamps of the isolator. Also in the disclosed embodiment mutually engaging surfaces of each of the jaw-like clamps and their respective flanges are knurled to provide enhanced resistance to longitudinal shear forces.

Title: Device for pelletizing vegetable material
Inventor: HAIMER FRANZ
IPC: A23K10/32
Filed: 1993-04-23
Abstract: A pressing or pelletizing device for compacting vegetable materials, in particular grass blades, is disclosed for use specially with a harvester. In order to reduce the pressing forces required for the pelletizing process, the pressing channels are heated up to a temperature above 100 °C, preferably above 150 °C. It bas been demonstrated that by heating the pressing channels, local overheating of tire device, which could otherwise lead to malfunctions, can be avoided. Appropriately, the pelletizing device has two co-axial hollow cylinders (33) in which the pressing channels (51) are delimited by radial lands (39) which alternatively engage the pressing channels (51) of the other hollow cylinder (33). The hollow cylinders (33) are heated by means of a liquid circuit guided through the lands (39) and linked to a heat exchanger that utilizes the lost heat from the internal combustion engine of the harvester.

Title: Inflatable swimmer's safety belt
Inventor: BROWN DENNIS
IPC: B63C9/15
Filed: 1994-11-28
Abstract: A first belt of the invention -- substantially hollow and worn about the waist -- is able to be filled with a compressed gas from a cartridge coupled with it and actuable by a pin whose placement is controlled by a pulling open of a belt buckle or by a pulling on an included lanyard. A portion of this first belt is secured in overlapping relationship so as to unfold and expand outwardly under action of the compressed gas which fills it. A second belt of the invention -- of conventionalconstruction and also worn about the waist -- underlies the first belt and is tethered to it. The end result is to increase the length of the first belt when filled with the compressed gas, thereby forming a tube riding under the armpits in holding a wearer vertically in the water -- yet still allowing him or her to be able to swim about, while the tether prevents the tube thus formed from slipping over the shoulders and head of the wearer.

Title: Converter arrangement having a low-inductance commutation circuit
Inventor: BERIGER CONRAD
IPC: H02M7/00
Filed: 1994-12-22
Abstract: A converter  circuit  arrangement  is  specified which  is  constructed  to  have  a  particularly  low inductance. This is achieved by the circuit area of the commutation circuit being kept as small as possible. A circuit area which is as small as possible is achieved by the branch modules and switch modules of a phase module  being  arranged either  in a U-shape  or  in  a meandering shape.  The branch modules can be arranged either  parallel  to  or  at  right  angles  to  a  main direction,   between   the   positive   and   negative connections and the load connection. In addition, it is advantageous if the power semiconductor switches and the reverse-connected parallel diodes and freewheeling diodes are arranged in separate stacks which are held together by means of a clamping-in device.

Title: Ergonomic computer desk
Inventor: BELL DAVID A
IPC: A47B17/06
Filed: 1995-01-19
Abstract: Currently available desks for personal computers are uncomfortable to use over long periods of time because the screen of the computer monitor and the keyboard are at different distances from the operator's eyes.  These desks are also inconvenient for referring to books, papers etc., when using the computer. This invention results in a desk which permits the screen of the computer monitor, the keyboard, and the working surfaces for reference material to all be at the same distance from the computer operators eyes. This makes the desk very comfortable to use.

Abstract: The present invention has an object to provide a compact quadrature modulator manufactured at low cost in such a manner that an input level is low over a wide high frequency band, and few input signals are wrapped around an output terminal.  The quadrature modulator is mainly constructed of a multi-layer substrate into which a 90-degree phase shifter is assembled, a semiconductor integrated modulator circuit into which two sets of 2-phase modulators and an output signal in-phase synthesizing circuit, and a lid.  The multi-layer substrate is constructed of "n" pieces of layers in total, namely from a first substrate corresponding to an uppermost layer to an n-th substrate corresponding to a lowermost layer.  The first substrate layer is a layer for assembling a semiconductor integrated circuit, or a layer for connecting a substrate with a semiconductor integrated circuit.  The 90-degree phase shifter is constituted by distributed coupling circuits having wavelengths of .lambda.g/4 by both of wiring patterns formed on the substrates corresponding to an intermediate layer of the multi-layer substrate.  A wiring pattern connected to a ground terminal and other circuit components are formed on the n-th substrate layer, i.e., the lowermost layer.

Abstract: In a packet network for electronic transfer of data packets from an end station to another end station there are, in the conventional way, a number of switch units.  Each end station is connected to a switch unit and the switch units perform the transfer of data packets along an established connection.  The switch units are provided with switch ports on all of its connections.  In these switch ports a substitution is performed of labels of the data packets, both for data packets arriving to a switch unit and for data packets forwarded from a switch unit.  It is performed in order to avoid that data packets belonging to different connections will have the same label and also for offering distributed services in the data network.  The data packet labels are constructed of a VPI field and a VCI field and for data packets, which arrive directly from or are sent directly to an end station, also a GFC-field.  In the substitution of the label of a data packet arriving to a switch unit, in the associated switch port first a table look-up is performed by means of the contents of the VPI field of the data packet. The result of the table look-up gives a direct information if the data packet belongs to a connection having a label comprising only a VPI field (VP connection) and then its contents are replaced by a record obtained in the table look-up.  If the data packet has both a VPI and a VCI field (VP connection), its VPI and VCI fields are replaced by new label portions obtained from a second table look-up.

Inventor: SHEN QUN
IPC: H04B1/12
Filed: 1994-04-28
Abstract: A method and apparatus is described for actively canceling a primary noise source to produce a desired noise level at at least one location. The apparatus comprises a signal processor which drives at least one actuator (H'), et least one error sensor (e(k)) and a primary noise reference signal (x(k)). The error sensors are positioned proximate to each of the locations. The output of the error sensors and primary noise reference signal are sent to the signal processor (312). The relationship between the driving output of the processor and the output of the error sensors is modeled by a block of filter coefficients (314). Based upon the model and the primary noise reference signal, the processor drives the actuator to generate a canceling noise at the location. The processor calculates differences between the desired noise level and the output of the sensors. A variable convergence factor and a gradient block are derived from the residual noise and are used to adapt the filter coefficients.
