Patent DE-4014952-A1 (DE)
Inventor: SCHNAIBEL EBERHARD DIPL ING
IPC: F02D41/24
Filed: 1990-05-10
Abstract: In order to determine the amount of fuel to be supplied to an internal-combustion engine with intermittent injection and to measure the air flow in the inlet pipe, the invention proposes, in contrast to prior art time-based injection control, a crankshaft angle-based control. Injection is carried out for a length of time (t alpha ) determined by the time taken for the crankshaft ( alpha ) to increase from zero to a pre-computed final value (fuel injection angle  alpha i), the integral of amount of fuel injected being adjusted independently of rpm, automatically and without delay, to the engine filling. At high rpm, and a correspondingly small amount of fuel supplied per injection, the number of injections per unit time increases, thus ensuring complete compensation.

Title: Introducing solids or fluids into a liq.-solid contact system - comprises liq. circulated through nozzle into space where it picks up solid particles before re-entering contact vessel
Inventor: SCHREINER HERMANN PROF DIPL IN
IPC: B01D11/02
Filed: 1990-05-23
Abstract: A circulating stream of liq is delivered via an adjustable nozzle into an open space leading to the mixing vessel, in such a manner that the stream of fluid exactly fills the cross-section of the entrance from the open space into the vessel. The liq leaves the nozzle at a velocity of 30 to 40 m/s and flows at atmospheric pressure from the open space into the mixing vessel.  The nozzle and the opening leading to the mixing vessel may be automatically varied in cross-section by a process control system. The liq is circulated from the contact vessel (1) via a pipe (9) and a pump (3) and enters the space (23) which is open to the atmos via a nozzle (33). There it picks up the solid particles being fed under gravity, and spreads into a flow pattern (25) which fully occupies the entrance to the mixing vessel (17).  Devices (33,35) are provided for adjusting the nozzle and the entrance opening (17). USE/ADVANTAGE - For introducing solids and/or fluids into a solid/liq contact or mixing vessel, in which the liq is circulated in a closed circuit. Such systems are found in drying and varnishing processes, and also in chemical reactors and mass- and heat-transfer systems. Larger solid particles than normal of regular and irregular shape can be handled in a continuous process, and pharmaceutical prods of up to 30 mm in size can be accommodated.

Patent DE-4022895-A1 (DE)
Inventor: KUMNIG FRANZ
IPC: B23Q1/00
Filed: 1990-07-18
Abstract: The invention relates to a spindle head with an arrangement for supplying the respective drilling and/or cutting tools with coolant and/or lubricant, the spindle being provided with an axial passage, fed via an opening of a stationary feed member, for the transport of the coolant and/or lubricant to the working area of the tool, the feed member and the spindle mating coaxially while a gap is formed. In order to reduce the occurrence of leakage flows in the gap and sealing loads associated therewith as well as wear phenomena, the axial passage of the spindle has a larger cross-section than the opening of the feed member. This results in a suction effect like a water jet pump, which suction effect manifests itself in a pressure gradient in the gap, as a result of which the occurrence of leakage flows is counteracted. <IMAGE>
