Title: Oscillation control in low voltage lighting circuit - initiating oscillation by pulse derived from time base, monitored according to criteria and also stoppable
Inventor: DIETRICH JUERGEN DR
IPC: H02M7/5383
Filed: 1992-11-19
Abstract: In a procedure for time control of an oscillation in a low voltage discharge lamp circuit supplied with either an AC or DC supply, the oscillation is initiated by a trigger pulse derived from a time base. The oscillation is monitored according to certain criteria and can be stopped after an arbitrary time lapse or in the case of malfunction, with the characteristic of not reacting integrally towards known malfunctions like short circuit and overload. The overload regime corresponding to the load and cold current behaviour of the lamp is designed so as to ignore stochastic overload signals and those during starting by using multiple interrogation with time delay. It also ignores periodically repeating overload signals of short time duration. ADVANTAGE - High accuracy and reproducibility of functions.

Title: Model for practising cardiopulmonary resuscitation (CPR) of a human being, especially of babies
Inventor: GUTTORMSEN TOM
IPC: G09B23/28
Filed: 1993-03-17
Abstract: A baby model for practising cardiopulmonary resuscitation is composed of a conventional doll's body (1) and a functional unit (2) which can be easily inserted therein. The functional unit (2) includes all necessary functional elements required for simulation of the thoracic resistance, the lung function and the like. Moreover, there is a switchable exhalation non-return valve (21) which prevents backflow of respiration air from the simulated lungs (20) to the mouth opening (31) for reasons of hygiene in one switching position, whereas it permits this type of backflow deliberately in the other switching position. In this switching position, it is possible to practise those measures that are necessary for eliminating a foreign body that has entered the airways. The simulated lungs (20) are represented by a bellows which simultaneously represents the spring device for simulation of the thoracic resistance (Fig. 2). <IMAGE>

Inventor: MINDEL KLAUS DR
IPC: B61L1/16
Filed: 1993-05-04
Abstract: A method for clear track signalling is disclosed in which axle count pulses which are acquired at counting points of a route area which comprises several sections of track are fed to a computer and stored thereby for each counting point in a direction-related fashion, in which method clear track signalling occurs for a track section if the same counter state is stored for the counting points which bound the track section and in which method correction of a counter state is performed when the counter states stored for the next two counting points in the direction of travel are the same and higher than the counter state to be corrected or when the counter states which are stored for the two directly succeeding counting points in the direction of travel are the same and lower than the counter state to be corrected. The correction takes place by approximating the counter state to be corrected and the counter states of the respectively significant adjacent counting points. <IMAGE>

Patent DE-4315213-A1 (DE)
Title: Water distributor for coffee machines
Inventor: PUEHLER THOMAS
IPC: A47J31/44
Filed: 1993-05-07
Abstract: In conventional coffee machines, a single water jet is delivered with a high inflow velocity into the product contained in the filter. In this process, the product contained in the filter is flushed away to the side and therefore not optimally utilised. The water distributor serves to reduce the inflow velocity and to divide the water jet into several fine water jets. As a result, the flushing-away of the product contained in the filter is prevented, the water is distributed evenly over the product contained in the filter and the latter is thereby better utilised. Fig. 2 shows the water distributor designed in the form of a lid, in plan. <IMAGE>

Title: Magnetic fastening of supplementary parts on spectacle frames
Inventor: KARP LEILA
IPC: G02C11/00
Filed: 1993-05-13
Abstract: The previous optical variation possibility of a spectacle frame in the form of supplementary parts is possible at present only by means of clamping or screw connections. The novel possibility of fastening is characterised in that the supplementary parts stay on the spectacle frame by fitting small magnets. They ensure the rapid and virtually wear-free exchange of the supplementary parts. Usually the supplementary part (2) is firmly (unreleasably) connected to the spectacle frame (3). Using a magnet (1b) on the supplementary part (2) and a second magnet (1a) on the spectacle frame (3) makes the connection releasable. The spectacle frame (3) is thereby provided with various optical variation possibilities. <IMAGE>

Patent DE-4325159-A1 (DE)
Inventor: BOCK HERIBERT
IPC: B65B69/00
Filed: 1993-07-27
Abstract: What is specified is a device and a method for handling the used packaging of a roll of web material, in which the web of material is freed of the end-face cover and of the circumferential wrapping in an unpacking station. The handling of the circumferential wrapping, which can attain a considerable size and a considerable weight, is difficult. The handling is to be simplified. For this purpose, a roll is produced from the circumferential wrapping and the roll is compressed transversely to its axis. Provided for this purpose is a folding device (5) which folds the circumferential wrapping (21) together in multiple layers and presses it flat, and a transport device (17) which is arranged between the unpacking station and the folding device. <IMAGE>
Patent DE-4327085-A1 (DE)
Inventor: MUELLER ROLAND
IPC: A47J31/46
Filed: 1993-08-12
Abstract: The invention relates to a device (1) for a machine for brewing drinks to heat and emulsify liquids, especially for the making of the milk-coffee drink "Cappuccino". The device (1) has a tube (2) with a nozzle (22) which adjoins the bore (10) in the lower section (5) and from whose outlet opening (24) superheated steam emerges, during operation. A nozzle (22) is surrounded by the tube (2) in such a way that an annular chamber (26) open in the flow direction (Y) results around it. The open end (18) of the annular chamber (26) extends beyond the outlet opening (24) of the nozzle (22). Formed on the tube (2) at the height of the outlet opening (24) of the nozzle (22) are passages (29) through which the air required for emulsification can penetrate into the annular chamber (26). Furthermore, means (30) are attached to the tube (2) which make it possible for the user to maintain a certain distance (L) between the outlet opening (24) of the nozzle (22) and the surface (43) of the liquid by visual inspection (40). By means of this device according to the invention, the handling during the milk frothing-up process is considerably simplified in that, with the aid of the visual inspection (40) via an operator, the distance (L) of the outlet opening (24) of the nozzle (22) from the surface (43) of the milk can easily be kept constant. As a result, for a simple design of the device (1) a good froth result is achieved and the frothing-up process is even accelerated. <IMAGE>
