Title: Establishing time synchronicity in third generation mobile radio system
Inventor: BRAAM REINHOLD
IPC: H04L25/06
Filed: 1998-10-27
Abstract: The receiver in a telecommunication system is presented with several reception data per symbol. The data are mutually displaced with sufficiently small time delay (over-sampling). Analogue-to-digital conversion and reception filtering is performed using two times over-sampling. In the following interpolator, intermediate values are calculated, so that data at the output of the interpolator are eight times over-sampled, and access to individual steps is possible by means of a shift register.  A RAKE receiver accesses the input data for providing its finger at suitable positions.

Title: Preparation of dough portions by extrusion under low pressure
Inventor: HELMSTAEDTER JOSEF
IPC: A21C5/00
Filed: 1998-12-16
Abstract: Preparation of dough portions by extrusion under low pressure.  The dough mass in funnel (7) gravitates into cylinder (1). This cylinder has a rectangular cross-section with the longest side horizontal. The closure (4) has a number of circular openings (5) through which the dough is extruded. A piston (12,13), together with an apron (14), provides the driving force for the extrusion by pneumatic cylinder (11). Initially openings (5) are closed by a pneumatically operated guillotine knife (21). The pressure in cylinder (11), which is proportional to the pressure on the dough, is monitored so that the guillotine frees openings (5) when the pressure on the dough is between 2 and 3 bar. A measuring device (15,16,17,18) indicates the travel of the piston, and hence the size of the dough portion, and triggers the action of the guillotine to sever the portions and close the openings (5). Alternatively a photoelectric switch could be used. A processor (25) controls the operations.

Inventor: KAUS WOLFGANG
IPC: F15B11/16
Filed: 1999-07-02
Abstract: The invention relates to a control device for supplying a pressure means to preferably, several hydraulic consumers. Said control device has a load-sensing-regulated variable displacement pump (10) whose setting can be varied according to the highest load pressure of the hydraulic consumers being activated, by means of an LS pump regulating valve (27); proportionally adjustable directional-control valves (38), which are situated between a supply line (12) extending from the displacement pump, a discharge line (63) leading to a tank (11), and the hydraulic consumers; and a load indicator line (26), through which the LS pump regulating valve can be subjected to the highest load pressure of the hydraulic consumers being activated at the same time. A control device of this type sometimes lacks the desired dynamics. The aim of the invention is therefor to further develop the known hydraulic control device in such a way that the displacement pump can continue to operate in an energy-saving manner with the usual LS behavior but if desired, can also operate with greater dynamics. To this end, arbitrarily switchable valve elements (60, 61) are provided. Said valve elements can be switched into a mode in which a pressure can be built up in the load indicating line from the supply line, by means of said valve elements.
