Title: Process for urea synthesis
Inventor: INOUE SHIGERU
IPC: C07C273/04
Filed: 1981-01-09
Abstract: An inert gas which contains carbon dioxide and ammonia separated from a urea synthesis off-stream under urea synthesis pressures is brought into contact with an absorbent together with unreacted carbon dioxide and ammonia which were separated in the high-pressure distillation at a gauge pressure of 10 to 25 kg/cm<2>, to absorb essentially all the carbon dioxide and the predominant proportion of the ammonia, and cooled to separate the liquid ammonia obtained and then removed. The inert gas can be treated by the above method with little or no risk of explosion.

Patent DE-3112386-A1 (DE)
Title: Compressor
Inventor: BAIER WOLFGANG
IPC: F04B37/16
Filed: 1981-03-28
Abstract: For a compressor, in particular for a two- or multi-cylinder compressor, there is provided, to increase the volumetric efficiency, a control device which acts as a function of the travel and which, in or near upper dead centre of the one piston, connects this compression cavity with a second cavity. This second cavity is advantageously formed by a second cylinder cavity in which the piston is in or near bottom dead centre. This ensures, in a simple manner, that the highly compressed gas from the clearance volume of the first compression cavity is used to recharge the second compression cavity in the end phase of the intake action and that said second compression cavity thus benefits from considerably better admission. At the same time, a larger amount of gas is drawn in in the first compression cavity, owing to the pressure drop during the subsequent intake action.
Patent DE-3117838-A1 (DE)
Title: Screening device
Inventor: HOPPE KURT ING GRAD
IPC: B07B1/48
Filed: 1981-05-06
Abstract: The invention relates to so-called tensioning-wave screening machines which have screening surfaces comprising screening elements which are in the form of strips and are lined up in rows. The screening elements are fastened, on the longitudinal side, on carriers, engaging one into the other in pairs, of various carrier systems which can be set in opposite swinging motions. As a result, successive screening elements are alternately tensioned and relieved of tension. The extent of their movement influences the screening intensity, it being possible to raise the screening output with increasing intensity only up to a defined limit. In the case of a screening device according to the invention, the screening output is further raised by the intensity of the screening being adapted specifically to the various regions of the screening surface. For this purpose, the screening elements are fastened on the carriers, starting from the supply side, with decreasing, average pretensioning. The high screening intensity desired in the supply region can thus, if appropriate, be further raised, but at least maintained, by a higher pretensioning of the screening elements, and, in the discharge region where a high intensity may be disadvantageous, it can be correspondingly lowered. Consequently, the screening output can be raised overall.

Title: Device for producing mixed water gases for an internal combustion engine
Inventor: HO KIM BYUNG
IPC: F02M25/022
Filed: 1981-07-31
Abstract: A device is described for producing mixed water gas at a high temperature and a high pressure for an internal combustion engine. The device is characterised in that an outlet chamber is divided into a middle space and two lateral spaces, which have two or more intake openings, three or more outlet openings and a vent opening. In the internal combustion engine a carburettor with a water injection device is provided, which introduces water into the carburettor by means of a water injection device, which is supplied from a water source, which is provided in the internal combustion engine. A heating device with one or more centre heating pipes and a plurality of heating pipes situated on both sides in the respective sub-divided spaces is provided. An open air supply pipe is connected to the intake system.

Title: Disc wheel for children's or dolls' pushchairs
IPC: B60B3/08
Filed: 1981-10-29
Abstract: A disc wheel which consists of two metal discs (1) which are connected in mirror-inverted fashion next to one another and to one another, have a finished surface and are shaped at their circumference in such a way that they are suitable for positioning a rubber tyre (4). In this arrangement, the two metal discs (1) have on their circumference a flange (2) which runs perpendicular to the axle (5) of the wheel and at which the two discs (1) are connected to one another. The rubber tyre (4) has on the interior of its outer surface (41) which is matched to the shoulders (11) of the two discs (1) a radial circumferential slot (44) with which it is positioned on the common flange (2). As a result, the processing and connecting points (10) of the two metal discs (1), which are preferably spot weld points, are not externally visible so that sheet metal which is already surface-finished can be used as the starting material for manufacturing the disc wheels and subsequent working of the metal discs (1) is dispensed with. <IMAGE>

Patent DE-3202976-A1 (DE)
Title: Needle-type printing head
Inventor: MOSER ERICH
IPC: B41J2/28
Filed: 1982-01-29
Abstract: The invention relates to a needle-type printing head, in which each printing needle is movable to and fro between a position of rest and a printing position, and in which each printing needle is assigned an actuating device consisting of an armature and of a magnet system. Arranged at the end of the printing needle (1) assigned to the armature (7) is a body which is guided round the armature (7) and which has an armature stop (6) located behind the armature (7) in relation to the printing needle (1). During the movement out of the printing position into the position of rest, the armature (7) is in frictional contact with the armature stop (6). The armature stop thereby experiences wear. In the position of rest, therefore, the printing needle (1) is shifted nearer to the recording medium by the amount of the wear. The length wear of the printing needle (1) is thereby compensated or at least reduced. <IMAGE>
