Title: Method of regulating water circulation in heating system - involves using heat pump driven by strong inflow of cold water
Inventor: FAUST HANS JOACHIM DIPL ING
IPC: F24H8/00
Filed: 1990-12-22
Abstract: A method of regulating the water circulation in a heating system uses a heat circuit pump with changeable output. The pump is driven by a strong inflow of cold circulating water into the boiler during the starting phase of the boiler out of a cold state in order to achieve optimum calorific value. At the end of a lowering phase the pump is driven with maximum otuput by a low to rapidly achieve a heat effective water temperature, but before exceeding the dew point of the heating gas. USE/ADVANTAGE - The jacket temperature of the boiler is kept in a copious condensation temperature for as long as possible.

Patent DE-4109177-A1 (DE)
Inventor: HAUPT ROBERT
IPC: B60T17/00
Filed: 1991-03-20
Abstract: The compressed air supply installation is intended especially for compressed air systems of vehicles. It comprises an oil-lubricated compressor (1) and units assigned to this, such as air cooler (1), oil separator (5), pressure regulator (6), air dryer (7) and air reservoir (8). At least some of these units are equipped with outlets (11-14) for condensate or air containing lubricating oil delivered during idling phases. All these outlets (11-14) are connected by lines (22-24) to a condensate collecting vessel (15) in which the condensate and lubricating oil are separated and collected. The air with the condensate and lubricating oil removed is released by way of a vent (26) into the environment. The environment is thereby at least largely relieved of the lubricating oil of the compressor (1) which in the case of known compressed air supply installations passed into the open air through their unit outlets. <IMAGE>

Title: Sandwich carbon granule absorption filter - has granules between e.g. polyester textile webbing, useful for air filtration
Inventor: CHRIST MICHAEL DIPL ING
IPC: B01D53/04
Filed: 1991-09-02
Abstract: An endless belt of textile webbing which incorporates active carbon granules and passes through an adsorbent air filter in a duct, has a limited adsorbent capacity. The novelty is that the belt is made of two layers between which are the pockets contg. active carbon granules; and that the belt passes through the duct at least four times in each cycle through a belt drive. The endless belt passes through the effluent duct in cycles which are multiples of two passages through the duct, per complete revolution through the belt drive. The textile web is pref. of polyester or glass fibres or of fibres (esp. with a PTFE or polyether- ketone coating). USE/ADVANTAGE - The vol. of adsorbent active carbon material incorporated is unrelated to the filter surface area. The carbon granules need not be glued to a textile substrate, the effluent air flow is repeatedly filtered, and the carbon granules cannot be removed by the flow. (5pp Dwg.No.0/12)

Title: Seal for vertically sliding window -  is used in motor vehicle and is bonded to glass to reduce friction of operation
Inventor: ROUILLARD FIRMIN
IPC: B60J10/04
Filed: 1991-09-05
Abstract: The vertical sliding window (1) of a motor vehicle slides in the gap between the inner and outer walls of the surrounding frame. The lower edges (3, 5) of the window frame support two lips (7a, 7b). These lips are not in contact with the glass and do not form a seal. Their function is solely to fill the gap between the window frame and the glass. A seal (8) is bonded to the glass (1) with adhesive in the region immediately below the window frame. The seal forms a sort of pocket which collects any water which passes between the lips (7a, 7b) and the glass. Any collected water is then drained away through the tubes (10a, 10b). The seal abuts against the underside of the window frames (3, 5) when the window is fully closed. USE/ADVANTAGE - Seal for sliding window in vehicle with low friction which facilitates manual opening and closing.

Patent DE-4209840-A1 (DE)
Inventor: DRASKOVITS GUENTER
IPC: F04C15/06
Filed: 1992-03-26
Abstract: A suction-controlled vane-cell pump is disclosed, whose pumped flow does not increase further above a determined speed of rotation but remains practically constant. Radially movable vanes (4) arranged in a rotor (2) form working chambers (12). Between the vanes (4), the rotor (2) has control slots (21) which cooperate with several outlets (22 or 22A) in a front plate (5) located in the pressure zone. The control slots (21) and the outlets (22 or 22A) are sized so that a reflux of oil under pressure can be avoided from a higher-pressure working chamber (12) into a lower-pressure working chamber. The outlets (22 or 22A) are closed by a valve (24) with movable tongues (25, 25A). During the opening stroke, the tongues (25, 25A) rest on a supporting body (26). Suction openings (13 and 13A) communicate with a suction chamber (14) through throttle bores (31, 31A) in order to limit the suction current. Wear due to cavitation can thus be avoided. The pump has a low running noise level and can be cost-effectively produced with a small volume.
