Patent DE-3916911-C1 (DE)
IPC: E03C1/30
Filed: 1989-05-24
Granted: 1990-10-18
Abstract: A device for cleaning clogged drains, consisting of a conventional aerosol can with outlet valve and protective cap, is to be improved in that it can be refilled with an environmentally friendly propellant and has an operator-friendly actuation lock. This is achieved in that the aerosol can (2) is filled with compressed air and, for its refilling, the region (14), enclosing the valve pin (13), of the protective cap (3) is extended as a free-standing cylindrical tube-shaped adaptor (16), and the actuation lock can be released by relative rotation of aerosol can (2) and protective cap (3). <IMAGE>

Title: Acceleration friction damper system - uses inertia weight to clamp friction surfaces onto moving rod
IPC: B60R19/26
Filed: 1989-08-25
Granted: 1990-08-16
Abstract: The friction damper (1) for impact and vibrations consists of a damper-rod (3) in a tube (2) between which is a friction piece in the form of a sensor mass (4) for transmitting frictional forces.  When the friction damper accelerates the sensor mass (4) touching the friction damper (1) is deflected. The torque produced by the deflected sensor mass (4) by means of a causes engagement of friction  sufaces (c,d), which produces acceleration-dependent frictional forces on the contact surfaces between the damper tube (2) and the damper rod (3).  The two opposite-facing sides of the damper  pipe tube (2) each have a cavity (8,9). USE/ADVANTAGE - The friction damper operates in conjunction with speed and acceleration.

Title: Regulating heating of single room, in hotel - using electronic control unit to operate electrically adjustable valves in hot water supply of respective radiators
IPC: F24D19/10
Filed: 1990-07-19
Granted: 1991-12-19
Abstract: At least two heating bodies or radiators (2, 3) supplied by the hot water circulation (6) of a central heating system (7) heat the room (1). The radiators are controlled separately by an electrically adjustable valve (8, 9) in the hot water supply (4) and electronic equipment (10), with means of entering working data and requirements and sensors (17), in particular for the room temperature. The equipment (10) produces control signals for the valves. In the outlets of the radiators (5) there is an additional sensor (12, 13) which gives a signal depending on the temperature of the hot water leaving a radiator and which is used by the electronic equipment to set the valves. The equipment from the signals of at least two sensors forms a reference signal, setting the valves so that the hot water leaving the radiators corresponds in temperature with that of the reference signal and so is the same at all radiators. ADVANTAGE - Improvement in control of heating process.

Granted: 1994-02-28
Abstract: FIELD: production of glass burden. SUBSTANCE: dosing auger of feeder 3 is mounted as that screw 8 of small diameter is disposed in remaining volume of material 10. The remaining volume of material 10 is defined by walls of discharge throat 7 of weight doser 1, first coil of screw 9 of large diameter and is defined from top by surface of angle of repose of material 10. Discharge window 4 is formed trapezium- shaped, with window side faced towards auger having an angle of 70-90 deg. with respect to surface of large-diameter screw 9. Discharge process is turned from discrete into continuous process, dose is lengthened and precision of dosage is immensely increased by reduced quantity of material discharged per time unit. Simultaneously compaction of material in discharge place (when the material is discharged on fixed support) is eliminated by reduced weight of material falling per time unit. Moreover, material 10 is discharged not in one point, but is distributed along a predetermined length of path. Processes recited are characterized not only by precise discharge, but also by approximated discharge to facilitate smooth dosage of material. Upon completion of dose distribution of material 10 on conveyor 6 a command for switching-off discharge auger feeder 3 is delivered in accordance with control system signal. Doser 1 has a predetermined portion of material 10 left there. This portion functions as variable container, i. e. correction volume for next discharge process. EFFECT: reduced compaction of material in auger and at the site of discharge, eliminated lumping of material, when it is prepared for mixing and, as a result, obtaining of homogeneous glass burden, increased precision of dosage due to the usage of screws of different diameters. 2 cl, 7 dwg
