Title: Heating-up circuit of a storage water heater
Inventor: TEPER HERBERT
IPC: F24D19/10
Filed: 1988-11-25
Abstract: To kill harmful bacteria, the domestic hot water is heated up at certain intervals to temperatures of around 80@C. The excess energy in the domestic hot water is then returned, according to the invention, to the heating circuit so as to avoid scalding and reduce the energy losses. This is effected in an intermediate heat exchanger (3) between the boiler circuit (1) and a domestic hot water circuit (4), in that charge pumps (2, 5) are maintained in operation until the temperature in the storage water heater (6) has dropped to the temperature set at the domestic hot water thermostat. <IMAGE>

Patent DE-3844073-A1 (DE)
Title: Trap release, in particular step release
IPC: A01M23/24
Filed: 1988-12-28
Abstract: The step release is used for releasing striking or gripping traps.   The area of use is land on which trapping with traps which have a trigger release is unsuccessful. Environmental awareness and the improvement of trapping results require trap releases which effectively come into operation where other trap releases are unsuccessful in order effectively to combat forest pests. This requirement is satisfied by the step release described by a release mechanism of special mobility being produced, which only brings about release of a trap when there is stepping contact of an animal on it. As releases of this type hold apart two centres of gravity of the trap which are to be moved towards one another, it is necessary that the release is of simple and safe connected type in order to be able to set it particularly rapidly and safely between the pressure points. This is possible as it uniquely consists of only two levers which are interconnected rigidly but movably. The difficult handling encountered in other very complicated step releases, which in some cases work with two to four levers, is eliminated. All trigger releases which are to be baited are unsuccessful in the case of passing through of an animal which, however, takes no notice of the bait and not suitable for productive trapping.
Patent DE-3844281-A1 (DE)
Title: Door-locking device for locking doors of all types on one side
Inventor: MEYR RUPERT
IPC: E05B13/00
Filed: 1988-12-30
Abstract: When locking doors of all types on one side, in particular bathroom doors and toilet doors, the relevant square spindle of the door lock is divided in two in the centre and, in the handles, is mounted displaceably to the right and left in corresponding shafts. By displacing the spindle to one side, the spindle part of the outer handle is released from contact with the lever mechanism of the catch and thus from its opening function. This state of being locked on one side is maintained until the inner handle is pressed down and the spindle is rotated out of an arresting means and springs back into the original position, which can be used by both handles.

Title: Pneumatic apparatus against earthquake damage as means, and process
Inventor: SCHATTA MARTIN
IPC: E02D27/34
Filed: 1989-02-21
Abstract: Pneumatic apparatus against earthquake damage as means, and process, the strong earth shocks being converted into mild earth shocks or into entire-building vibrations by means of fillable pressure cushions. A box-shaped foundation bed and a floor slab retained in the mounting profile form the building-displacement area in which the pressure cushions or folding-type coverings and vehicle tyres function as building-displacement pneumatics. They are triggered by means of a ball weight falling onto an impact valve due to earth shocks. In order to reduce large earth-shock double amplitudes, the peaks of which generate a high pneumatic pressing pressure, peak-pressure reducers are arranged on the respective pressure pipe connections. Consequently, the single basic principle of designing a building such that it vibrates vertically in a resonance-free manner is used for the subject matter of the invention. For example, it can be used from a count of five on the Richter scale.

Title: Self-supporting composite panel
Inventor: RUF HEINZ DIPL PHYS DR
IPC: E04F15/024
Filed: 1989-03-04
Abstract: There is a composite panel for self-supporting installation 1, in the case of which a thicker composition layer 3 which hardens due to a mineral binder is provided on a thinner load-bearing layer 2, and in the case of which a means 4 for connecting load-bearing layer 2 and composition layer 3 is distributed over the load-bearing layer. In this arrangement, it is desirable for the ratio of loading capacity of the panel to weight of the panel to be improved by an improvement in the connection of load-bearing layer and composition layer without increasing the production outlay. This is achieved in that a full-surface bonding layer 4 is provided as means for connecting load-bearing layer 2 and composition layer 3. By using the bonding layer, the ratio loading capacity of panel to weight of panel is increased considerably. <IMAGE>

Abstract: A change-speed gearing with a driveshaft and driven shaft (2 and 3, respectively) rotating coaxially in the same direction, in which driveshaft and driven shaft can be locked relative to one another with the aid of clutches (8, 9) to obtain a rotational speed which is the same for both shafts, is to be designed so as to be constructionally simple and also compact even in the case of high transmission ratios. For this purpose, the gearing is designed as a planetary gearing, in which the sun gear (1) is fixedly connected to the driveshaft or driven shaft (2 and 3, respectively) and the revolving carrier (4) is fixedly connected to the respective other driveshaft and driven shaft (2 and 3, respectively) which do not form one piece with the sun gear (1). The planet gears (6) of the revolving carrier (4) mesh in a ring gear (5) which is mounted to be rotatable about the common axis of driveshaft and driven shaft (2 and 3, respectively) and to be lockable with respect to the gearing case (7) by a clutch (9). The driveshaft or driven shaft (2 and 3, respectively) connected to the sun gear (1) can be fixedly connected to the revolving carrier (4) via a further clutch (8). Of the two clutches (8, 9), during gearing operation in each case one must be opened and one closed in order to obtain, on the one hand, the same and, on the other hand, different drive and driven speeds. To obtain different, especially high, transmission ratios, a plurality of shiftable planetary gearings can be arranged in series. <IMAGE>
