Filed: 1990-06-02
Abstract: A stream of test-gas, or of test-material entrained in carrier gas, is discharged from the open end of a first chromatographic sepn. column (10) to enter the first end of a generally T-shaped connector (11), from which a lateral branch leads to a detector (16), possibly with a recorder (17) for identified materials.

The main column is mounted in a hollow sealing block (19), e.g. of graphite or synthetic material, permitting the column to reciprocate along the connector main arm, with the extreme positions of the column outlet extending to both sides of the conduit entry point. In a variation the connector is dome shaped instead of T-shaped, and the connector conduits all enter from one of a common housing.

Title: Digitally controlled frequency multiplication for square wave signals - counting integer pulses in up-counter and passing result to down-counter producing corrected output pulse
Inventor: STEINBACH GEORG DIPL ING
IPC: G06F7/68
Filed: 1990-07-11
Abstract: Higher frequency pulses (fc) are counted between consecutive rising edges of an input signal (f ein).  The integer multiplication factor pulses (ft), produced by a dividing stage (2), are counted by an up counter (3) and passed as a resultant (Zg) to a down counter (6) via a buffer register (4). The down counter (6) produces a pulse at the desired output frequency (f aus) each time the zero count condition is reached.  The re-loading of the down counter (6) with the resultant (Zg), and subsequent production of an output pulse (f aus) at the zero count condition, continues until a new cycle between input signal (f ein) edges is initiated. USE/ADVANTAGE - Suitable for motor drive applications.  Linear response to frequency changes.  Fast response time.

Title: Decision logic for prioritising and synchronising async. signals - is for multiprocessor with access to global bus using two synchronisation, priority and masking logic stages
Inventor: FRANK ULRICH DIPL ING
IPC: G06F13/364
Filed: 1990-07-28
Abstract: Decision logic for prioritising and synchronising to a reference clock for asynchronous request signals for access by a number of processors to a global bus contains a first synchronisation stage (81), a prioritisation logic (P) and a second synchronisation stage (S2) for each processor in series. Connections for invidiual request signals (e1-en) can be blocked by masking logic (M) connected in front of the series circuit. A combination of request signals synchronised by the first stage is converted by the subsequent stages to a prioritised sequence (a1-an) which triggers the transfer of information for a corresp. sequence of processors. Combinations are blocked by the masking logic according to signals fed back from the prioritisation logic. USE/ADVANTAGE - Enables signal throughput time and circuit costs to be reduced for multiprocessor system.

Patent DE-4040352-A1 (DE)
Title: Curing thermosetting resins in plastics - comprises monitoring temp. throughout layout to indicate point when exothermic reaction finishes and heat supply can be cut-off
Inventor: HEBEL WILHELM VON
IPC: B29C65/02
Filed: 1990-12-17
Abstract: Thermosetting resins are cured under heat and pressure in a bonding process, where the energy used in the reaction is specific to the materials concerned. The amount of the energy used is monitored during the curing process so that the course and the end of the reaction are recorded for efficient utilisation. A conventional multi-daylight hot press is used, with its platens heated by suitable liquid. The temp. is measured at a number of points by thermocouples which are connected to a recorder with integral computer. The points are located at the heating oil feed and return, and various other places. The total heat supplied to the press equals the total heat lost. If the heat lost is greater or less than the heat supplied, the system must have an exothermic or endothermic reaction respectively. Monitoring the heat flow therefore can indicate whether the curing process is continuing or has already finished. In the first stages the temp. rises from room temp. and the exothermic reaction causes a steep rise. After a time the heat used drops off; this is a secure indicator that the cure reaction is nearly finished, and no further heating is required. ADVANTAGE - The mechanical strength of the prod. is appreciably higher than hitherto and its values lie within a strikingly narrow range. No energy is wasted. If the course of the reaction is not normal this is recognisable and can be interrupted. The measurements made do not come from direct connections to the material so that the set-up can be made a fixed layout.
Patent DE-4104592-A1 (DE)
Title: Epitaxial deposition of high temp. ceramic superconductor on silicon@ - using an intermediate layer of which the first part is deposited by sputtering in an oxygen-free high pressure ambient
Inventor: BEHNER HEINRICH DIPL CHEM DR
IPC: C23C14/02
Filed: 1991-02-14
Abstract: Epitaxial deposition of a ceramic superconducting material (22) on a single crystalline Si surface (5) is carried out via an intermediate layer (4a, 4b) of an oxide which has a lattice constant close to that of Si and that of the superconductor. The improvement is that the first stage (4a) of deposition of the intermediate layer consists of sputtering some atomic layers, pref. a thickness of 5-50 microns esp. 10-25 micron, in an oxygen-free ambient at a sputtergas pressure of at least 0.5 mbar, pref. at least 1 mbar. The sputtergas used is pref. at least a single noble gas. During the deposition of the intermediate layer the substrate is pref. heated. The intermediate layer is pref. one of the following: SrTiO3, BaTiO3, LaAlO3, NdAlO3, NdGaO3, MgO, MgAl2O4 or Y-stabilised ZrO2. The sputter equipment is pref. an RF-magnetron. USE/ADVANTAGE - The deposition of the first layer prevents growth of an amorphous oxide layer on the Si which prevents epitaxial deposition. The high pressure of sputtergas atoms causes thermalisation of the O-ions from the oxide target, reducing the rate of oxide growth. Afterwards normal sputter conditions can be set up. The method is used in the integration of superconductor layers with Si ICs's
