Patent DE-4305570-A1 (DE)
Inventor: JAERVINEN JYRKI
IPC: A62B18/02
Filed: 1993-02-24
Abstract: A gas mask (1) comprises a set of inlet channels (4) for incoming breathing air, a filter (10) and a separate exhalation channel (5) for exhalation air. The channels (4) comprise in lot branches (6, 7) directed to the sides of the mask, of which one can be provided with a filter (10), if desired, and the other one can be closed by a closure (11). Using this arrangement, the same mask can be provided to suit either a right-handed or a left-handed wearer. The branches (6, 7) are joined together on the vertical center line of the mask into one vertical channel (8) which divides the incoming air essentially evenly to the area of windows (3) of the mask. The windows are maintained clean from condensing humidity with the aid of the air flow. When branches (6, 7) are joined together into one channel (8) directly on top of channel (5), the exhalation air can be arranged to heat the incoming air with the aid of a heat-conducting metal partition 14. <IMAGE>

Title: Drying of protein compounds, in particular of protein hydrolysates and protein-fatty acid condensates
Inventor: CARDUCK FRANZ-JOSEF DR
IPC: A61K8/65
Filed: 1993-03-03
Abstract: Fine particle, pale-coloured, free-flowing protein compounds can be obtained from their aqueous solutions, suspensions or pastes by drying. The moist material to be dried is passed at the same time as a hot gas, in particular air, with an inlet temperature of at least 100 DEG C to 250 DEG C, in particular 150 DEG C to 200 DEG C, into an elongate drying container, and the material to be dried is rotated together with the hot gas around the long axis and is moved axially and is discharged at the end of the drying container. The drying process is both economic and temperature-sparing. Relatively high throughputs can be achieved without impairing the product quality, especially the colour of the product.
Patent DE-4319637-A1 (DE)
Title: Bag tearing-open and emptying press
Inventor: CHABORSKI JUERGEN DIPL ING
IPC: B65B69/00
Filed: 1993-06-14
Abstract: For tearing open and splitting up refuse bags filled with recyclable material, there is a refuse-bag press which is arranged between a conveyor delivering the refuse bags and a sorting band. This press has a feed funnel and a tearing chamber as well as a press piston which presses the refuse bags entering the tearing chamber through the latter, the refuse bags being at all events torn open because they are of course, at the same time, fixed by the slitting-open parts of the tearing chamber, but at the latest are fixed by the discharge, or the associated slide, arranged on the end face of the tearing chamber, in such a way that splitting up is at all events guaranteed. This twofold splitting up guarantees that the recycling material delivered in the closed refuse bags is exposed completely. <IMAGE>
Patent DE-4321458-A1 (DE)
Inventor: JABS ARNO
IPC: H04L12/24
Filed: 1993-06-29
Abstract: State of the art: A plurality of autonomous communications networks (KND, KNE) which are in each case managed by their own network management system (NMED, NMEE) are interconnected. Operators communicate by telephone. Technical problem: Network management tasks can be performed only unsatisfactorily with communications links via a plurality of these autonomous communications networks (KND, KNE). Underlying principle: The network management devices (MED, NMEE) exchange status information (CONFIG, STATISTIC, STATUS) with one another via a data network and make this available to the respective network operator (D, E). Solution: Each network management device (NMED, NMEE) requests from each other device selected information on the network components managed by the latter and with this represents graphically the status of the entire network. Advantages:     - Simple end-to-end fault management - Advantageous implementation of customer networks ('customer network management') - Network technology can be monitored centrally by a network management device.   <IMAGE>

Title: Arrangement for non-contacting control of the outlet temperature (discharge temperature) and the water flow at a tap, in particular with a flow heater for heating water
Inventor: GROITL JUERGEN
IPC: G05D23/19
Filed: 1993-10-08
Abstract: The invention relates to an arrangement for non-contacting control of the water temperature and of the amount to a tap which, for the purpose of hot-water supply, is provided by an electronically controlled flow heater preferably with electric power or gas energy in order to heat the water. Within an effective range of a sensor system, which operates without making contact, for localising a body, a logic assignment of water temperatures and amounts is carried out in the case of the presence of a body. After programming, these values are assigned permanently and directly to the individual room regions together with the associated room coordinates and are set by means of a control electronics by means of control signals. The control of the temperature is carried out by means of the electronically controlled metering of the heating power of the flow heater. The control of the amount of water is carried out by means of electromechanical actuating valves, in particular magnetic valves.
