Abstract: HYDRAULIC CONTROL SYSTEM FOR VEHICULAR AUTOMATIC TRANSMISSION            Abstract of the Disclosure The present invention provides a hydraulic control system for the automatic transmission of a vehicle.  The control system utilizes only one pulse width modulating valve to provide modulated pressure to whichever of the torque transfer devices -- in the nature of clutches and brakes -- constitutes the single, on-coming torque transfer device required to effect the drive ratio selected in accordance with electrical control signals from an on-board, pre-programmed computer.  The control system accomplishes its objective by cascading a plurality of relay valves which are coupled to preferably latching, solenoid valves (A through E) which are also controlled by computer.  A control valve is interposed between the single, pulse width modulating valve and the plurality of cascaded relay valves to provide both modulated pressure (P3) and main line pressure (P1) to the various torque transfer devices of the transmission. The computer controls the solenoid valves (A through E) to determine which of the torque transmitting devices shall receive line pressure (P1) and which shall receive modulated pressure (P3).  In this regard it is noted that the on-going torque transfer device is always actuated by modulated pressure (P3).  Moreover, the control system is adapted for operation with vehicular transmissions that provide one more forward drive ratio than the number of torque transfer devices in the transmission.

Title: Method of transmitting different commands relating to the choice of transmitter antenna in a time multiplex radio communication system
Inventor: ERIKSSON HAAKEN OLOV
IPC: H04B7/06
Filed: 1991-05-07
Granted: 2000-01-18
Abstract: The invention relates to a method for transmitting, in a time-multiplex radio communication system, for instance a GSM-type (Global System For Mobile Communication) mobile telephony system, different commands from a movable station to a fixed station with respect to the selection of transmitter antenna in the fixed station. Each transmission sequence from the movable station includes a synchronizing word which consists of a predetermined number of binary bits. The different commands are transmitted by using different synchronizing words in dependence on the command to be transmitted. The movable station has access to at least two different synchronizing words. The synchronizing words used in addition to a standard synchronizing word are formed by the binary bits from the standard synchronizing word being shifted laterally to mutually different extents and/or in mutually different directions in order to generate different, new synchronizing words. In this way, there is formed in the receiver of the fixed station an impulse response having a pulse which occurs at different time points depending on which synchronizing word was used by the movable station.

Title: Metal utensil
Inventor: KUHN JACQUES
IPC: A47J36/08
Filed: 1992-04-03
Granted: 1996-02-27
Abstract: The invention shows how a metal utensil with handles shaped onto the marginal portions thereof can be manufactured in a simple, material-saving manner. Such a utensil can be used in a more universal manner than conventional utensils.   The metal utensil comprising the container part (10) and/or the lid part (15), with handles (4) for holding the utensil, is characterized in that the handle parts have at least one handle attachment (12) for fixing a handle (4) shaped onto the rim of the opening.   As a result of the special shaping of the handle attachments a system utensil is obtained, with e.g. significantly improved stackability, reciprocal usability, e.g. bain marie cooking and more extensive uses, e.g. as a pouring, steaming or sieving vessel.  Through shaping and the use of heat distributing laminated materials a local overheating in the vessel is virtually impossible and a uniform heat distribution over the entire vessel surface is ensured. The handle attachments 12, e.g. as carriers of heat insulating handle parts (4), can be extended a long way out, which ensures a maximum distance from the heat source.
