Abstract: A mechanical device comprising; a base which is attached to the lower side of tables that are found on typical furniture at public telephone locations. The base has a hinge and a dashpot.      Attached to the base by the hinge is a frame and a piston. The piston interacts with the dashpot on the base. On the piston is a seal and which controls the interaction between the piston and the dashpot. A typical binder with spring closing covers is fastened to the frame by it's back cover with the back of the binder in a more or less vertical position when the binder is in the storage position. When not in use, the binder with it's book, hangs below the table. A rest protrudes from the table of the telephone furniture in a position where it supports the binder when the binder, on is's frame, is hinged forward and upward from below the furniture to a horizontal position in front of the table, and opened. The rest supports the binder while it is open. The binder with it's book is easily held open with light downward pressure on the front cover with one hand. When the downward pressure is released, the springs in the covers of the binder close the binder and it returns below the table. The speed of the return is controlled by the piston and dashpot device.

Abstract: A systems management subsystem provides resources for managing components and allows components to be manageable. In particular, state information about managed components is encapsulated into objects that are visible in the global name space. The state of a single component may be partitioned into subcomponents that are stored in separate objects. These objects may, in turn, be encapsulated into a single container object that is associated with the managed component. By placing the state information in the global name space, local processes and remote processes may both gain access to internal state information and properly manage the component.

Abstract: Disclosed is a method and system for data compression. In a preferred embodiment, an input stream of data bytes are compressed into an encoded stream using an LZ77-based scheme. The preferred method searches for a matching sequence of already processed data bytes that is identical to a current sequence of bytes. Sequences of literals (bytes not forming part of a matching sequence) or match codes (encoded matching sequences) are identified by count values indicating the number of literals or match codes in the sequence. Preferably, the encoded stream is transmitted from a first computer to a second computer, where the encoded stream is decompressed. The method uses matching circular history buffers for compression and decompression, the history buffers being synchronized using a coherency byte included with each frame of encoded data transmitted. If an encoded frame is not received by the decompression device, the decompression device transmits a flush request to the compression device. The compression device flushes its history buffer in response to the flush request, the flushing step making the previously processed bytes stored in the history buffer incapable of becoming part of a matching sequence. The compression device includes in the coherency code of the next encoded frame a control code indicating whether a flush request has been received by the compression device.

Title: High concentration homogenized collagen compositions
Inventor: CHU GEORGE
IPC: A61K8/65
Filed: 1993-02-16
Granted: 2009-02-03
Abstract: High concentration collagen compositions having improved persistence when administered for soft tissue augmentation are prepared from both cross-linked and non-cross-linked collagen starting materials. Suspensions of the starting materials are subjected to vigorous mechanical disruption to reduce the average collagen fiber size to below a threshold level which enhances the injectability of the composition. Thus, both enhanced injectability and enhanced persistence may be achieved using the same formulations.

Abstract: A method for measuring electric voltages and/or electric fields by the use of a crystal with an electro-optical (Pockels) effect. To this end, in a direction transverse to the direction of propagation (y direction) of a light wave polarized in the z direction, an electric field intensity gradient is generated in the crystal in the direction from which results a corresponding gradient in the refractive index of the crystal. This produces a deflection of the light wave in the crystal which depends upon the field intensity, and on emergence, it is used as a measure for the voltage of field intensity. A suitable sensor for this purpose also is described.

Abstract: A flexible coupling of the type having hubs secured to aligned shafts and connected to one another through the use of a flexible belt surround-ing the hubs is improved by forming axial and circumferential grooves on the exterior surface of the belt, each circumferential groove lying transverse to and opening into an axial groove. A cooperating metal retainer ring has respective pins formed on its interior surface for insertion into the axial grooves. After a test for gross misalignment has been satisfied, the respective pins are rotated into the circumferential grooves, thereby fixing the retainer ring in position with respect to the flexible belt and coupling. The belt further has nine wedge-shaped projections, each conformably fitting with a receptacle in a cooperating hub, each receptacle rotatable into a position where it lies vertically above the shaft on which the hub is mounted, each receptacle further providing inside diameter support to the belt through its mating relationship therewith.

Abstract: A process for eliminating organic pollutant residues in the synthe- sis gas occurring during refuse gasification by the addition of oxygen is described, in which at least prepyrolyzed, carbon-cont- aining refuse in compressed form is fed into a high temperature reactor, where a loosely heaped up gasification bed is formed and is burnt below the same by O2 addition. The resulting synthe- sis gas is drawn off from the top area of the high temperature reactor after an adequate residence time and into the residence zone additional oxygen is jetted in temperature-regulated, partial quantities in such a way that the resulting possible partial combu- stion of the synthesis gas maintains its temperature above the gasification bed constant at approximately 1000°C. Oxygen jetting takes place in such a way that a completely homogeneous gas mixing is ensured in the top area. For this purpose several oxygen jets are arranged in the top area of the high temperature reactor and are axially and/or radially inclined thereto.
