Title: Multi-cylinder internal combustion engine with lower cylinder communication
Inventor: HUDOCK DANIEL S
IPC: F02B75/18
Filed: 1996-09-27
Abstract: A multi-cylinder internal combustion engine cylinder block is formed with communication ports allowing communication between cylinders that, when assembled with pistons and a crankshaft, are 180° out of phase. This allows the trapped mass of air beneath a piston to flow beneath a piston ina different cylinder 180° out of phase. As a result, advancing and returning pistons are matched to effectively balance pressures.

Title: Process and device for the analysis of glucose in a biological sample
Inventor: ESSENPREIS MATTHIAS
IPC: A61B5/00
Filed: 1995-04-26
Abstract: A method  for  the  analytical  determination  of  the glucose concentration in a biological sample. In a detection step,  light  is  irradiated  into  the  sample  and  the  light emerging therefrom after interaction with the sample emerges therefrom is detected in order to measure a physical light property   affected   by   said   interaction.   The   glucose concentration  is determined  from  this  measurement  in  an evaluation step. To provide a method for determining glucose in  reagent-free  and  non-invasive  manner,  the  invention proposes that a portion of the light emitted by the light source be  guided along a reference  light path of  defined optical  path  length  to  the  photodetector,  that  the  total measuring light path also has a defined optical length and that  the measuring light path after  it  has  traversed the sample is so combined with the reference light path that the measuring light and the reference light interfere with each other. The photodetector measures an interference signal used in the evaluation step to determine the glucose concentration.

Abstract: Traffic in a multiple ring transmission system is advantageously routed via alternate rings should a ring fail. Upon the failure of a ring, a hunt is first undertaken to establish the available restoration capacities within the rings. Next, a selected set of available restoration capacities is reserved (selected) to optimize the transmission of traffic between a destination node and an origin node. The selected set of restoration capacities are then cross-connected to route traffic between the origin and destination nodes.

Title: Network design for both compressed and uncompressed atm cells
Inventor: CHEN HOWARD ZEHUA
IPC: H04L12/56
Filed: 1997-06-24
Abstract: A method and apparatus for reducing bandwidth in an ATM network.  The invention provides an ATM switch having a compression module for compressing ATMcell headers without affecting the virtual circuit established for the call.  The compressed headers provide the ATM switch buffers with extra space to handle more cells for a given call.  To realize the benefit of the extra space during transmission, the present invention provides a mapping interface between the PHY and ATM layers of the ATMcommunication.  The mapping interface separates the compressed headers from the uncompressed headers into two different PHY payloads. The cells transmitted in the compressed payload are then expanded in an expansion module located in the call destination switch.  The expansion module returns the compressed headers back to their original form.

Inventor: SKIPTUNAS STEVEN J
IPC: G01N35/08
Filed: 1996-05-31
Abstract: In an apparatus (10) for fluid analysis, such as hematologic analysis, a plurality of reagent-mixture components are each injected by a respective pump (P1...Pn) through a valve matrix (16) and into a flow-injection unit (24). The flow-injection unit (24) defines a mixing chamber (50) including a plurality of protuberances or nubs (54) projecting inwardly toward the center of the chamber, and spaced relative to each other both axially and radially. As the reagent-mixture components are injected into the mixing chamber (50), the nubs (54) agitate the fluid flow and create turbulence, thereby dispersing the reagent-mixture components and in turn mixing the components together to create a reagent mixture. The flow rates of the reagent-mixture components are adjusted in order to select the reagent-mixture ratio as the components are combined in the flow-injection unit (24) to thereby create the selected reagent mixture. Upon passage through the flow-injection unit (24), the reagent mixture is injected into a sensing unit (20) for analyzing a particle distribution of the mixture.

Abstract: The present invention concerns the improvement of a static reading head, having the capability of processing, indeferently, data cards of the inductive type and chip-cards provided with contact pads on their surface . The raising and lowering of connection pins (49) which contact said pads is achieved by linking the pin supporting plate (48) to rockin g C-shaped driving arms (41, 41'), having bifurcated free upper ends (42) slidingly coupled to pivots (43, 43') which are attached to said plate. The lower limbs of said arms extend parallel to the lower face (47) of the upper part (30) of the reading head, said limbs having bo sses (54) facing said lower face, the gap (45) between said bosses and said face being roughly equal to the thickness of an inductive card. The greater thickness of a chip-card presses down said bosses bringing about a clockwise rotation of said C-shaped arms around a fixed shaft (44), resulting in a lowering of the connection pins which touch the contact pads on the card surface.
