Patent DE-3023648-A1 (DE)
Inventor: EICHLEV RUEDIGER ING GRAD
IPC: A61M15/00
Filed: 1980-06-24
Abstract: To permit accurate introduction of aerosols containing, for example, irritants or similar substances, into the pulmonary tract or airways of a patient, the breathing cycles of the patient are counted and, after a number of normal breathing cycles, and during a limited period of time in the inhalation phase of a breathing cycle, and after commencement of the inhalation phase, a predetermined quantity of aerosols is introduced to the patient by applying compressed air of controlled pressure to an atomizer or aerosol fog generator (32, 34); initiation of inhalation is sensed, for example by a pressure transducer (24), the output of which is connected to a threshold stage (50) sensing inhalation and exhalation, respectively, and setting a time delay period for example of less than half than normal duration of the inhalation phase of the patient, which then triggers a timing interval by a monostable flip-flop (56) which, during the time period thereof, applies the controlled compressed air to the atomizer (32, 34), the compressed air being shut off, and thus terminating atomization well in advance of the end of the inhalation cycle, and preferably less than 1/2  second, for example less than 0.3 second, so that the quantity of aerosols is accurately controlled and will reach the alveoli to be absorbed in the lungs so that the breathing tube will be essentially free from contaminating aerosols.

Title: Reinforced rotor blade head - has elastic loops around opposing pairs of blade mountings
Inventor: STEPHAN MICHAEL DIPL ING
IPC: B64C27/32
Filed: 1980-10-07

Title: Control circuit - uses comparator to control output voltage from LC circuit between static converter and load
Inventor: HUECKELHEIM KLAUS
IPC: H02M7/155
Filed: 1980-12-20
Abstract: The control circuit has a comparator circuit (12) for comparing the output of a voltage regulator with the current in the capacitor's branch of the LC circuit. The regulator forms the difference between the desired and measured voltages across the LC circuit. The comparator output is passed to a current regulator (13) whose output is added (14) to a signal derived from the load input current, the supply voltage and the required value of the LC circuit's voltage. The current regulator is coupled to the controller (15) that controls the converter's thyristors.

Title: Beaker for slicing the top off an egg
Inventor: ZIMMER PETER
IPC: A47G19/28
Filed: 1981-01-16
Abstract: When opening soft-boiled eggs there are always problems due to soiling. With the present invention of a "beaker for slicing the top off an egg" this problem, especially for children and older people, is largely eliminated. As is depicted on the accompanying drawing (1), according to the invention the egg, inserted in the beaker with its tip upwards is cut open with a knife. After removing the upper part (2, Fig. 2) of the "beaker for slicing the top off an egg", the cut-off top of the egg is then lifted off. Moreover, the upper part 2 of the "beaker for slicing the top off an egg" is used both as an egg warmer and also as a waste beaker. <IMAGE>

Patent DE-3104135-A1 (DE)
Title: Apparatus for comminuting plant stems and stalks
Inventor: MILLER CHARLES E
IPC: A23N15/02
Filed: 1981-02-06
Abstract: The apparatus for comminuting plant stems and stalks is composed of a cylindrical plant reception chamber, which is held so as to be rotatable about a first axis, and of a cylindrical cutter support which grips round the outside of the chamber so as to be in abutment with it and is held so as to be rotatable about a second axis which is offset with respect to the first axis and extends essentially parallel to it. A number of cutters which are held on the cutter support extend radially through assigned cutter apertures into the plant reception chamber. A drive device rotates the plant reception chamber and the cutter support at the same speed, which results in each cutter executing a reciprocating movement with respect to the assigned cutter aperture in the course of one revolution. Notches are provided in the cutters to receive the stems and stalks of the plant and to pull them towards the inside of the walls of the plant reception chamber, the plant parts being cut into pieces as the cutter movement continues.

Title: Single-lever mixer fitting
Inventor: GROTH GUENTHER
IPC: F16K11/078
Filed: 1981-02-16
Abstract: The invention proposes a single-lever mixer fitting with a valve body and control discs of ground ceramic material arranged therein and with an operating lever which acts on the control discs and can be adjusted about the axis of the valve body and obliquely to the axis of the valve body, two separate motion systems being provided for flow rate adjustment and temperature adjustment, these systems leading to two linear movements directed transversely to one another. For this purpose, the control disc designed as the flow rate regulating disc is arranged in a manner which allows it to be displaced linearly and the flow rate regulating disc and the temperature regulating disc are arranged in a manner which allows them to be moved jointly in linear fashion relative to the inlet disc, transversely to the first-mentioned direction of motion. It is advantageous in this arrangement that when the temperature setting is changed the flow rate remains unaltered and vice versa. Advantageous mechanical connections and improvements in terms of manufacture and assembly are furthermore described.

Abstract: 1 Treibstangenbeschläge, die in Längsnuten der Rahmen von Fenstern, Türen od. dgl. verlaufen, sind mit Haltemitteln versehen, welche von den Nutseitenwänden ausgehende Rippen untergreifen, wobei die Treibstange oberhalb der Rippen verschiebbar gelagert ist. Um einerseits einen möglichst großen Ablängbereich der Treibstange zu schaffen und andererseits trotzdem eine gute Führung an den Treibstangenenden zu erhalten, ist die Treibstange mit einer in Höhe der Rippen entsprechend abgesetzten Abkröpfung zum Nutgrund versehen. Das freie Treibstangenende gelangt infolgedessen in den Nutbereich unterhalb der Rippen und wird somit am Austreten aus der Längsnut gehindert.

Abstract: A temperature-control device with liquid heat-transfer medium, in particular for plastics processing machines. The invention relates to a temperature-control device with liquid heat-transfer medium, which is used in particular for the temperature-control of plastics processing equipment. The aim and object of the invention are to provide a temperature-control device with low space requirement and high operating reliability, which maintains a constant preset temperature of the heat transfer medium under all operating states occurring, without increased equipment outlay. The solution provides for the cooler in a temperature-control device consisting essentially of tank, submerged pump, heater and cooler, as well as appropriate pipelines, to be installed in an enclosed housing provided with a circulation pipe and for said housing to be arranged in the tank. The open end of the circulation pipe is located at the top in the cooler housing and the lower end provided with bores projects out of the housing into the tank. The cooler housing is connected to the pressure connector of the pump and is acted on by heat-transfer liquid which partly flows back to the consumer and partly flows, via the circulation pipe, back into the tank.

Title: Flue-gas pipe probe holder for determining the turbulent core flow in furnaces
Inventor: MERKLE WILLI
IPC: G01N1/22
Filed: 1981-12-24
Abstract: Probe holder which can be mounted in the measuring hole of a flue-gas pipe which is such that two segment-like clamping jaws are extended outwards at the face of the hole by means of an adjustable eccentric in the measuring hole and are clamped together with the probe introduced. The probe holder is additionally held with the aid of a preferably trapezoidal radial recess in the clamping jaws as a result of interference with the wall of the flue-gas pipe and provides adequate swivelling freedom for the probe between the clamping jaws. In addition, a permanently installed adapter ring in the flue-gas pipe can be used to optimise the reception, sealing and thermal insulation of the probe holder and the measuring hole can be sealed by a trapped closure cap after measurement has been completed.
