Abstract: A translation look-aside buffer (TLB) (10) for translating a variable page size virtual page number (VIRTUAL ADDRESS) to a physical page number (PHYSICAL ADDRESS) partitions the virtual page number into an upper portion (UPPER) and a lower portion (LOWER). The upper portion is always compared to an upper virtual page number entry in a first content addressable memory (14) while only certain bits of the lower portion are selectively compared to a corresponding number of bits in a lower virtual page number entry in a second content addressable memory (16). The number of bits compared in the second content addressable memory is determined by the specified size of the physical page. The TLB includes a page size memory (18) having a plurality of page size entries wherein the certain number of bits for each of the lower virtual page entries is specified by a corresponding page size entry. Associated with each bit in the lower virtual page number entries is an enable transistor for selectively enabling the comparison of that bit in the lower virtual page number entry, in dependence on the corresponding bit in the page size entry. A victim TLB can be coupled to the main TLB (10) in order to improve the overall hit rate of the combined TLBs. <IMAGE>

Title: Improved airflow in trash chamber in open end spinning unit
Inventor: WASSENHOVEN HEINZ-GEORG
IPC: D01H4/36
Filed: 1996-02-16
Abstract: An open-end spinning unit has an opening roller (2) with a rotary airflow (24) in a housing (3) fitted with a trash chamber (15) and pneumatic trash removal.  The trash chamber (15) has two distinct airflow systems.  A suction connection (17) together with an atmospheric air inlet (22) produces a relatively high speed (vST) transport air stream (23) which brushes over the entire floor region (16).  This stream (23) is in the same direction as the rotary flow (24) induced by the opening roller.  An opposing flow (25) is induced by an opening to atmosphere (21) above the suction connection (17) resulting in stagnant zones (26,27) and so giving separation from the transport air stream (23).

IPC: F01M1/18
Filed: 1996-04-15
Abstract: A system for monitoring the bearing temperatures of e.g. a 2-stroke IC engine incorporating a crosshead drive for the crankshaft via a connecting rod (7) employs temperature responsive sensors at the shell bearing surfaces (20) of each of the connecting rod (7) bearings.

Inventor: FINGER HELMUT DIPL ING
IPC: F01L1/34
Filed: 1996-12-18
Abstract: In a device for determining the opening and closing times of a valve 1, 2 which can be opened by lifting off a closure element 3 from a valve seat 4 and can be closed by bringing the closure element 3 into contact with it, the valve forms a contact switch in an electrical circuit. In this context, at least one electrical variable can be sensed by an evaluation unit 5, it being possible for the opening and closing times of the valve 1, 2 to be determined from said electrical variable. The valve may be an inlet valve 3, fig. 1, the stem 11 of which is received in a conductive guide sleeve 8 which is isolated from the cylinder head 14 by an insulating sleeve 9. An insulating cup tappet 6 is used. A contact 10 on the guide sleeve 8 and an earth contact 13 on the head 14 are connected to a low voltage source and the time profile of the voltage of the circuit is evaluated digitally by unit 5. In the case of a fuel-injection valve, fig.2, a circuit including earth contact 13 and contacts 10 and/or 13 is closed when the valve element 3 contacts the valve seat 4.
Patent DE-19706496-A1 (DE)
Inventor: WINKLER OLIVER
IPC: G06F1/32
Filed: 1997-02-19
Abstract: The invention relates to a clock pulse supply system for a microcomputer system in which flexible power management drastically lowers the power consumption of the overall system during both normal and stand-by operation of the microcomputer. At the same time, through this quasi-decentralized clock pulse supply, flexible power management also ensures the greatest possible functionality. Furthermore, making available additional clock pulse rates also adjusts performance in line with the prevailing requirements. The invention further relates to a sleep mode by which the clock pulse supply system can be switched to a stand-by-like operating mode which is similar to the power-down mode but from which it can be woken without a hardware reset or interrupt. By means of a so-called intelligent power-down mode the module groups and/or individual modules are switched off or switched down only when an active data transfer or protocol run has been fully completed.

Title: Method for cleaning heating body lamellas
Inventor: STEINDORF OLAF
IPC: F28G13/00
Filed: 1997-07-04
Abstract: The process works by means of the accompanying movement of dirt particles and/or their removal. The laterally accessible intermediate spaces of a heating body are cleaned by means of a rotating brush with suction. Rotation energy is imparted to the brush by a rotor or an electric motor located in the suction path. The pressure difference can be produced either by a vacuum cleaner-type apparatus by means of a vacuum produced on one side, by an excess pressure producing apparatus, e.g. a blower or high pressure cleaner, or through a combination of both. As cleaning bodies, specially formed foam bodies, brushes or liquids (gas-form or fluid) are suitable.
