Title: Domestic roasting apparatus
Inventor: GELDMACHER ERWIN HELMUT
IPC: A23N12/08
Filed: 1983-01-04
Abstract: In a domestic roasting apparatus, for green coffee or similar material to be roasted, having a stand containing heating wires and a fan transporting air over the heating wires, which stand has at the top a hot air outlet closed by a mesh, on which outlet can be mounted a vessel made of transparent material, preferably glass, for receiving the material to be roasted, to protect the user from burns because of the high temperature of the glass vessel and to avoid overfilling the vessel, the mesh (10) forms the end of a hollow base (6) which can be inserted and locked into the hot air outlet (4) of the stand (1), to which base is attached a bag (11) made of a high-temperature-resistant plastic film furnished with a multiplicity of air outlets (15), containing a predetermined amount (12) of material to be roasted. <IMAGE>

Title: Device for detecting ignition failures
Inventor: SPAUDE HEINZ-W DIPL ING
IPC: F02P17/12
Filed: 1983-02-24
Abstract: In a device for detecting ignition failures, needle-pulse-shaped output signals are generated by means of a high-pass filter circuit which is capacitively coupled to the individual ignition lines, which signals are connected with the severe voltage change occurring with the onset of the ignition spark. Output signals characteristic of the nominal ignition times are generated by means of a reference stage. This stage comprises a storage section which is set by the reference stage output signals and is reset by the high-pass filter output signals. In the processing and logic stage, a timing section is provided which defines a window period which begins with the onset of the ignition voltage rise and is limited to about 100  mu ms and thus corresponds to about the period which elapses with voltage idling of the ignition coil until the peak of the available ignition voltage is reached. This prevents output pulses generated by means of the high-pass filter circuit, which occur only after the maximum available ignition voltage has been reached, from falsely being interpreted as signals characteristic of correct operation of the ignition system.

Title: Method and apparatus for determining the heat losses due to incomplete fuel combustion
Inventor: MILOVIDOV BORIS ANDREEVIC
IPC: G01N31/12
Filed: 1983-03-03
Abstract: In the novel method for determining the heat losses due to incomplete fuel combustion, samples of the combustion products are periodically collected and divided into two parts, one of which contains the gaseous phase and the other the solid and the gaseous phase. The oxygen concentration in each part is measured. The two parts are then heated and burnt and the oxygen concentration is determined after combustion. The oxygen decreases in the gaseous phase and in the mixture of the solid and gaseous phase are determined. The heat losses due to the chemical and total unburnts of the fuel are determined as a ratio of the oxygen decreases. The heat losses due to the mechanical unburnt of the fuel are then determined as a difference in the heat losses due to the total chemical and mechanical unburnts of the fuel and the chemical unburnt of the fuel. The apparatus for determining these heat losses has two chambers 6, 12 for afterburning the sample which contain electrical heaters 10, 15 communicating with one another via a valve 9. The chamber 6 contains a partition 11 of porous material for retaining the solid phase of the sample in the chamber 6. A device 16 sucks the sample into the chambers 6, 12 and a measuring instrument 28 determines the heat of reaction. <IMAGE>

Title: Distributing valve
Inventor: SCHWENKLER FRITZ OTTO ERNST DI
IPC: F16K11/085
Filed: 1983-07-06
Abstract: A distributing valve for the distribution of a fluid from one into at least two further pipelines. It has a housing with at least three inlet and outlet apertures which extends to a circular opening and are provided for the connection of pipelines. In addition a distributing element is provided in the opening of the housing. By means of the new distributor valve it is possible to shut off or reverse or to distribute or collect fluids, especially in the case of measuring lines. In so doing, either all outlets are closed or the inlet is connected to the first outlet or to the second or third outlet, or the inlet is connected to the first and second outlet or to the first, the second and the third outlet. This is achieved by a component which fills the width of the opening and has a through-recess which runs symmetrically relative to its centre axis and either widens in a funnel shape towards one side or has additional bores running in the angle to the recess which, when the distributor valve is opened, coincide with the outlet apertures of the housing.

Title: Display device and its use
Inventor: LITTWIN BURKHARD DIPL PHYS
IPC: H01J17/49
Filed: 1983-07-20
Abstract: In a plasma panel having spatially separated electron generation and subsequent acceleration, the control structure (4) is built up as follows: a first control plate (11) is provided on the rear and front sides with line conductors (14) and column conductors (15) respectively. A second control plate (13), placed in front of said first control plate (11), carries further conductors (tetrode conductors 16) on at least one of its two sides, which further conductors run parallel to the conductors of one of the two other conductor families ("selection conductors"). In each case n tetrode conductors (16) are allocated to the selection conductors. Wherever its two conductor families cross, the rear control plate (11) is in each case perforated once (inlet channels 17), while the front control plate (13) has in each case one opening (outlet channel 19) at the intersection points of its tetrode conductors (16) with the conductors running at right angles thereto, so that n outlet channels are associated with each inlet channel. The estimation ba</=be<nba+(n-1)bs (ba,e,s = width of the outlet channels, inlet channels and webs between adjacent outlet channels, measured at right angles to the selection conductor extent) applies to the cross-sections of the inlet channels. In one preferred embodiment, the display is used for representing coloured images on the basis of three primary colours, the column conductors acting as selection conductors and corresponding to in each case three tetrode conductors. The proposed control element has few connections, permits a representation with a strong light and sharp contours, and allows ... Original abstract incomplete. <IMAGE>

Title: Method for driving a self-commutated invertor
Inventor: DEPENBROCK MANFRED PROF DR
IPC: H02M7/521
Filed: 1983-09-29
Abstract: In this self-commutated invertor, which is suitable, for example, for supplying asynchronous motors, one or more branch pairs are provided in doubler connection, each branch pair having two semiconductor valves (1a...1f), for example GTO thyristors, which can be turned on and off purely by control measures, and two uncontrolled semiconductor valves (2a...2f) which are connected to one another in the manner of an unbalanced single-phase bridge circuit. The DC poles of the bridge circuits are connected to one another by means of in each case one preliminary inductor (3r, 3s, 3t) whose centre taps form the load connecting points (R, S, T) of the branch pairs. In normal operation, the effectiveness of the preliminary inductor inductance is varied continuously from its full value to zero by means of control measures in such a manner that, on the one hand, the higher harmonics of the load currents are limited, and in such a manner that, on the other hand, an additional reduction of the stalling torque of an asynchronous machine which is connected as a load is avoided in the event of severe field weakening. To this end, the controlled semiconductor valves (1a...1f) which are allocated to a bridge circuit are operated with mutually overlapping switch-on intervals in order to produce an additional DC current which flows magnetically in the same direction via both partial windings (3a...3f) of a preliminary inductor (3r, 3s, 3t). In the event of faulty turning-on of both control valves (1a...1f), the complete preliminary inductor inductance is always [lacuna] for limiting the surge short-circuit current ...

Title: Retaining structure for fastening roofing and facade slabs consisting of sandstone
Inventor: KARRAS UWE
IPC: E04D1/36
Filed: 1984-05-14
Abstract: Roofings and facade hangings with sandstone slabs are fastened by retaining structures and processes in a lasting and cost-effective manner. By raising the stone slabs, these retaining structures can be pushed underneath and then connect the stone slabs to the roof lathing by hooks. Since the slabs are held at the lower edge, they are safeguarded to a high extent against plunging downwards, e.g. in the case of fracture. In addition, they are also safeguarded against dampness, this being ensured by plastic panels being fitted on the retaining structure. The cost-effectiveness is achieved by the elimination of the labour-intensive transport of the slabs when re-laying a roof, since the slabs remain in situ.

Title: Oral hygiene device resembling a finger stall
Inventor: YUEH WEI-YI
IPC: A46B9/04
Filed: 1984-08-11
Abstract: The invention relates to a novel oral hygiene device which differs completely from conventional devices and is intended, in particular, to replace conventional toothbrushes. The device resembling a finger stall is made of rubber, a synthetic plastic or another material having equivalent properties, the parts used for the actual cleaning operation being integrally formed with the finger stall. The novel device comprises a cover which can be pulled over the index finger (3), the base (1) of the actual finger stall and a bristle part whose individual bristles (2) extend from the cover at least over a considerable part of its surface towards the outside. The length and softness of the individual bristles (2) may vary. As a result, it is possible to brush the teeth after introduction into the mouth, and in addition irritation or even injury of other parts of the oral cavity, especially the gums, is ruled out. Moreover, there are no dead angles in the oral cavity because of the particular manoeuvrability made possible by the subject of the invention. For this, the terminal phalanx of the finger is moved or turned at its joint, and this results in an as yet unknown cleanliness of the entire oral cavity and has corresponding health consequences. <IMAGE>
