Abstract: A device for use as a convenient, easy-to-use, and inexpensive pump for pumping water is disclosed which uses water pressure from a standard garden hose connected from a tap to the pump apparatus as the motive power to pump between seven and eleven times the volume of the water from the garden hose from a reservoir into a discharge hose which is any of several different standard sizes and which is connected to the pump apparatus. The water from the garden hose flows into the pump (10) through a pump inlet (14) having a reduced diameter venturi (32), which increases the velocity of the water, into a pumping chamber (40) with the resulting drop in pressure creating a vacuum in the pumping chamber (40). The vacuum in the pressure chamber (40) draws water from a reservoir the pump is placed in through a reservoir inlet chamber (20) into the pumping chamber (40) in the pump body (12), and the water exits the pumping chamber through a pump outlet (16) located on the opposite side of the pumping chamber (40) from the pump inlet (14).

Abstract: 2.1 In the actuation of a roller shutter, more or less substantial generation of noise inevitably takes place, in particular in the case of metal roller shutter slats. The new roller shutter slat is intended to reduce this generation of noise. The new method is intended to permit simple and economic manufacture of such roller shutter slats. 2.2 According to the invention, the walls of a metal roller shutter slat are provided with coatings of different layer weights. The correspondingly asymmetrical distribution of weight on the walls results in damping of the vibrations of the entire system, and hence in a significant reduction of the generation of noise. According to the proposed method for manufacturing such a roller shutter slat, an aluminium strip is initially provided with a plurality of adjacent longitudinal layers of different layer weights. The coated strip is divided into longitudinal slivers with at least two adjoining layers. The slivers obtained are converted to the roller shutter slats according to the invention by conventional roll forming. 2.3 Sound-adsorbent roller shutter slats and their manufacture. <IMAGE>

Abstract: In this method, destination calls requested in elevator cabins (CABIN.1 ... CABIN.n) in elevator control systems with immediate assignment of the destination calls requested at the floors (E0 ... EN) are treated according to an algorithm (CONTROLLER.K) implemented in the process computer (COMPUTER). Preliminary treatment of the cabin destination calls is effected when they are requested and final treatment of the cabin destination calls is effected before the floor of the cabin destination call. Cabin destination calls coinciding with assigned destination calls are immediately assigned during the preliminary treatment. The remaining cabin destination calls are shortened by one floor and recorded. The cabin destination calls recorded during the preliminary treatment are assigned in their original length during the final treatment in case there are similar assigned destination calls. The final treatment of the remaining cabin destination calls is effected as a function of the assigned destination calls before and/or after the floor of the cabin destination call.

Abstract: A dehumidifying system uses a membrane cartridge (16) to filter water vapor from air or other gas introduced into the membrane cartridge via a main pump or compressor (15). Dehumidified gas from the membrane cartridge (16) is then delivered into a system (20) which requires dry gas. The dehumidifying system further includes valve arrangements (18) or additional compressors which provide gas flow through the membrane cartridge when the main compressor is inactive. Therefore, the membrane cartridge (16) receives a substantially continuous flow of gas which maintains the optimal efficiency of the membrane cartridge. In addition to the arrangements which provide this continuous gas flow, a heating coil wrapped around the membrane cartridge raises the temperature of the fiber membranes within the cartridge. The heated fiber membranes are less susceptible to retain moisture which decreases the efficiency of the membrane cartridge.

Abstract: In an arrangement for the regenerative braking of electronically speed-controlled three-phase AC motors, there flows in a bridge circuit for each phase a control alternating current which is in a suitable angular position and is modulated by a transverse control direct current, which is not influenced by it, in such a way that control alternating current half-waves are steplessly shortened. These shortened control current half-waves are used after suitable conditioning to drive a three-phase inverter, to be precise to resupply the electrical energy available as direct current in a buffer store by virtue of generation from a three-phase AC motor into the public three-phase mains. The arrangement is undertaken in such a way that a continual transmission of the available energy that is to be resupplied is performed. The arrangement is constructed such that it does not interfere and is not subject to interference. <IMAGE>

Abstract: A method and apparatus are described for determining characteristics of peripheral arterial volume and compliance. A blood pressure cuff (10) is inflated and deflated around a limb of the body and pressure measurements are taken. The volume of air removed from the cuff is determined in a quantifiable manner, such as by expelling air through an orifice of known characteristics or by means of a volume of know characteristics. The detected pressures and volume of air removed are used to compute oscillation volume, which in turn is used to display arterial capacity and compliance as a function of transmural pressure and time. Arterial capacity may be displayed in terms of arterial radius, arterial cross-sectional area, or arterial volume. A display of these characteristics as a function of pre and post anesthetic administration is particularly useful to the anesthesiologist and surgeon.
