Patent DE-4136865-A1 (DE)
Title: Overpressure eddy reactor - has lower connection at cylindrical vessel for the eddy jet which forms a closed circuit with the lower outlet
Inventor: TURGAY HUEDAI
IPC: B01F13/10
Filed: 1991-11-07
Abstract: The cylindrical vessel of the overpressure eddy reactor, to clean sewage soiled by organic matter, has an upper outlet connection for the activated mixt. and the foam disperser,. At the lower end there is a connection to empty the cylinder and allow a closed circuit to be formed for the mixture. The entry inlet connection at the lower end of the cylinder, gives a tangential inflow, which can be connected to the lower outlet to form the closed circuit and also give the insertion of the special eddy jet into the cylinder vessel. The eddy jet is pref. in two tubes, within each other. The outer tube with the compressed air connection, is welded to the jet head. The inner tube, with the connection for the sewage and return foam mixture, opens into the mixing zone in the jet head where the bacteria agglomerates and air bubbles are reduced. The mixt. is forced from the mixing zone by pressure pumps and compressed air at a tangent into the cylindrical vessel, which keeps the matter rotating. The function of the reactor is based on an overpressure. ADVANTAGE - The appts. gives a high O2 delivery and breathing activity, with min. energy requirements and space for the assembly, for universal application in relation to reaction and vols.

Title: By pass for water heater to prevent drips from overflow - consists of by pass valve fitted to cold supply which opens to allow water through it and through water jet pump
Inventor: BRAECKER ERNST-EMIL DIPL ING
IPC: F24H1/18
Filed: 1991-11-29
Abstract: The attachment includes a water jet pump (7) which exerts pressure above the operating threshold level in an associated equalising chamber (8) by opening a tap fitting (1) connected to the overflow (3) and located in the water supply (4) between the cold water pipe network (2) and storage cylinder (5). This frees a volume in the chamber to take expansion water arising from the heating process. Between the tap fitting and the storage cylinder there is a by pass valve (9) fitted in the water supply (4) which opens when opening pressure threshold value exceeds operating threshold value in the water jet pump. ADVANTAGE - The pump is worked by comparatively low throughput of water with high throughput through the water storage cylinder.

Title: Safety window grip - has cylindrical roller easily rotated to draw back closure bolt from baseplate
Inventor: KOLB HORST
IPC: E05B13/10
Filed: 1992-02-22
Abstract: The window grip consists of a hand grip (1), a baseplate (2), an operating roller (3), and a double closure lock (4) which in all closure positions automatically moves under the return force of a screw spring (5) into the arresting holes (6) of the baseplate, preventing undesirable turning of the grip. Unlocking for adjustment of a new position is only possible if pressure is applied to the grip to effect a pushing movement upwards, activating the operating roller (3) to effect a rotation through approximately 90 deg. against spring force. In this event, the driver bolt (7) of the lock bolt (4) slides into a reducing dia. recess (8) in the operating roller (3), causing the bolt (4) to be withdrawn from the holes (6). USE - For opening and closing windows, balcony and terrace doors.

Title: Mounting bracket for cable ducts, such as breastwork ducts, on a wall etc.
Inventor: KLEINKORRES UWE
IPC: E04F17/08
Filed: 1993-02-09
Abstract: The invention relates to a mounting bracket for cable ducts, such as breastwork ducts, on a wall or the like. It consists of a plurality of basebodies which are in the form of plates and whose position with respect to one another can be varied using fixing devices. The mounting bracket has a mounting angle bracket on one side which can be fitted to the wall and a connecting angle bracket on the other side. For its part, this holds (in a detachable manner) a coupling which can be used to produce a connection to a cable duct. In order to ensure that a cable duct snaps onto such a mounting bracket even when said mounting bracket essentially has a smooth-walled base, it is proposed according to the invention that the coupling, which is constructed as a snap-action element, be connected to an adaptor which, for its part is connected to one of the walls of the cable duct, preferably to its base. The adaptor is preferably a metallic, integral body which has a centre part (which is used for the detachable fitting of the coupling) and at least one side mounting part. Mounting elements such as bolts, screws, nuts, blind rivets or the like which are known per se, can be passed through the apertures in the mounting part in order in this way to achieve a permanent connection of the adaptor to the outside of the base of the cable duct.
