Patent DE-3413419-A1 (DE)
Title: Device for introducing additional gas flows into the intake port of a mixture-compressing internal combustion engine
Inventor: AUGUST PAUL DIPL ING DR
IPC: F02M1/00
Filed: 1984-04-10
Abstract: The device serves for the introduction of additional gas flows (air, exhaust gases, cracked gases) into the intake port (39) of a mixture-compressing internal combustion engine (11) by means of slots (9, 10) lying opposite one another in the intake port wall downstream of the throttle valve (2) and extending in the circumferential direction of the intake port (39) over a circumferential angle of less than 180 DEG , to which slots the additional gas is fed through one or more feed lines (6, 7, 8, 14, 15, 19, 20), a control element (5) being provided in each feed line in order to control the rate of flow of the additional gas through these feed lines as a function of the vacuum prevailing in the intake port (39). At the same time the slots (9, 10) are so aligned that that parting surface which divides the intake port (39) and is produced by displacement of the longitudinal axis of the throttle valve shaft (21) parallel to itself along the longitudinal centre line of the intake port (39) is not perforated by any of the slots. An arrangement of this type leads to good mixture preparation and as a result to improved thermal effectiveness of the internal combustion engine for a reduced fuel consumption and reduced toxic gas constituents in the exhaust gas.

Title: Process for abrasive blasting using compressed air
Inventor: NASSENSTEIN HEINRICH PROF DR
IPC: B24C1/00
Filed: 1984-04-21
Abstract: A description is given of a process for abrasive blasting using compressed air, a granular abrasive being conveyed and accelerated by a carrying air stream, the main stream, and, in order to moisten the abrasive by means of an additional air stream, a liquid, in particular water, being introduced in distributed form into said main stream. In the case of said process, virtually optimum relative dust laying is achieved by the liquid being introduced into the main stream in the form of a dispersion with a gas as the dispersed phase. Air or an inert gas can be used as the dispersed phase. Use of inhibitory gases, decontamination gases or gases containing corresponding substances can also be used as the dispersed phase, and in certain applications they are very expedient.

Title: Process for extracting ethane and higher-molecular hydrocarbons from a hydrocarbon-containing crude gas
Inventor: KUMMANN PAUL DIPL CHEM DR
IPC: F25J3/02
Filed: 1984-07-27
Abstract: A process is described for extracting ethane and higher-molecular hydrocarbons from a pressurised hydrocarbon-containing crude gas by means of rectification. The crude gas is cooled and expanded in a plurality of stages, and the condensates produced are fed to a rectification column. A top product consisting essentially of methane, and a bottom product consisting of ethane and higher-molecular hydrocarbons, are obtained. In order to save energy it is proposed to cool the crude gas and/or the product streams in a plurality of pressure stages connected in parallel, to expand the cooled high-pressure gas by means of an expander and to feed the condensates, which are produced upon cooling and expanding, to the rectification column separately. <IMAGE>

Title: Drier for pourable material to be dried such as wood chips, wood fibres, cereal grains or the like
Inventor: WALSCH HANS-JOACHIM
IPC: F26B17/14
Filed: 1984-10-24
Abstract: A drier is described for drying wood chips, wood fibres, cereal grains and other material to be dried with a series of guide surfaces which are arranged in a staggered manner in relation to one another in steps in the vertical direction and run in each case downwards at an angle to the vertical central plane. In order that such a drier, if possible with a simultaneous improvement of the overall heat economy, requires a considerably lower construction height and decisively increases the operational safety, it is envisaged that the guide surfaces are air-impermeable and directly heated, that each guide surface is assigned, at its lower end, an adjustable air-impermeable flap in such a manner that guide surface and flap form a funnel slide which can be closed on the outlet side, and that at least two columns arranged parallel to one another vertically are constructed from the funnel slides.
Patent DE-3440943-A1 (DE)
Title: Process and device for continuous measurement
Inventor: GOERMAR HELMUT DR ING
IPC: B29C48/92
Filed: 1984-11-09
Abstract: With complicated, highly jointed profiles made of thermoplastics, for example plastics hollow window profiles, which are usually produced by extrusion, it is important that after their production they have the planned outer dimensions as accurately as possible. It is difficult to achieve this particularly because in general a plurality of specified dimensions must be maintained simultaneously so that the profiles fit perfectly and accurately together with other components, such as counterprofiles etc., during their further processing. The continuous monitoring of all important dimensions of the profiles during their production is made possible according to the invention in that a measuring device surrounding the profile is guided thereon in a longitudinal direction so as to be essentially non-slidable such that, in its entirety, it follows all movements of the profile transversely to the profile travel direction.

Title: Device for destacking in layers
Inventor: PFEIFFER ULRICH
IPC: B65G59/02
Filed: 1984-12-05
Abstract: During the destacking in layers of elongated stack elements 1 by pushing off further stack elements located beneath the former stack elements and acted upon by a restraining device 27, there is a danger that the downwardly arched stack elements 1 will collide with the restraining devices 27, causing operation to be disrupted. In order to avoid disruptions due to tilting of the individual stack elements 1 of a stack layer which is to be pushed transversely or longitudinally at one or more of the restraining devices 27 which hold the stack layer located therebeneath, provision has been made for allocation to the restraining device 27 of a scanning element which can be controlled from the top of the stack element 1 to be pushed off and takes the form of a scanning shoe 28, and for the scanning shoe 28 to control the position of the restraining device 27, with the distance between the scanning shoe 28 and the restraining device 27 being somewhat larger than the thickness of the individual stack elements 1. <IMAGE>

Patent DE-3515877-A1 (DE)
Title: Tunnel furnace with two parallel ducts
Inventor: RIEDEL RUDOLF
IPC: F27B9/30
Filed: 1985-05-03
Abstract: The tunnel furnace serves for the heat treatment of, for example, clay or porcelain and is a so-called countercurrent furnace, in which the product stacks (P1, P2) are guided in opposite directions through the two ducts (1, 2). The ducts are separated by a central wall (3) provided with passage openings (10) above and below the product stacks and are in each case divided into a heating zone (A1, A2), a baking zone (B1, B2) and a cooling zone (K1, K2). Between the heating zone of one duct and the neighbouring cooling zone of the other duct, a transverse convection (Q) takes place which makes the heat of the cooling zone useable in the heating zone of the other duct. This transverse convection (Q) is disturbed by a longitudinal convection (L), which flows between the baking zone and the external atmosphere, in such a manner that the heat balance of the furnace, which in itself is very good, is worsened. The invention now provides, above and below the product stacks (P1, P2) in each duct (1, 2), a number of flow guide surfaces (12) which, in the transport direction (T1, T2) of the products, form an angle ( beta ) of 30-80 DEG , preferably 50-70 DEG , with the central wall (3) and in each case end next to the passage openings (10) on the central wall. On each guide surface, a part of the longitudinal convection is in this case deflected in the direction of the transverse convection in such a manner that the longitudinal convection is weakened from guide surface to guide surface and at the same time contributes to the drive of the transverse convection (Fig. 3).

Patent DE-3535434-A1 (DE)
Title: Regulation method for boiling in water
Inventor: RILLY RERALD
IPC: F24C15/10
Filed: 1985-10-04
Abstract: When water is heated in a saucepan on an electrical heating plate or hotplate equipped with a temperature sensor, the use of a regulation method prevents the water boiling off as a result of too much energy being supplied. The method provides that the quantity of water is determined. The continuous temperature changes are then detected at fixed time intervals. As soon as at least two successive measurements result in a zero change, the power supply is restricted, so that boiling off does not occur.
