Title: Device for measuring the frequency of an electrical alternating voltage
Inventor: MARCORDES RALF DIPL ING
IPC: A61B5/0245
Filed: 1981-09-14
Abstract: This alternating voltage is, in particular, an action voltage derived from a human heart. The lower and upper limits of an operating range within which the frequency counter operates correctly are defined by threshold devices with different operating voltage. The transgression of the respective thresholds is indicated by visual signals, for example light-emitting diodes. The device can therefore be easily and faultlessly used by non-experts. <IMAGE>

Title: Method for producing transfer prints by the resist technique
Inventor: EINSELE ULRICH DR
IPC: B41M5/035
Filed: 1981-10-30
Abstract: A method for producing transfer prints by the resist technique is characterised in that a resist paste is printed onto printed transfer papers, which paste contains a substance (resisting agent) which prevents the sublimation of the colorant situated below the resist paste, no chemical reaction taking place between the resisting agent and the colorant and it being possible for the transfer print to be carried out from the paper to the textile substrate under the generally known conditions. Natural and synthetic polymers, in particular cellulose derivatives, can be used as resisting agent. The printing of the papers with the resist paste can take place by the methods customarily used for printing transfer papers.
Patent DE-3143475-A1 (DE)
Title: Photoelectric force measuring device (optoelectronic force measuring device)
Inventor: BARTKOWIAK KLAUS
IPC: G01L1/24
Filed: 1981-11-03
Abstract: The main function of the "photoelectric force measuring device" (optoelectronic force measuring device) is the electrical measurement of very small forces by incident flow or acceleration. In this case, it is possible simultaneously to obtain a plurality of components of the measured variable, so that the size and direction are measured. The fundamental principle is based on the elastic bending of an optical fibre. Size or size and direction of the bending can be converted into signals in various ways optically and electrically. Glass fibres embody outstandingly expedient mechanical and optical properties for this purpose. Possible measured variables are flow velocity, sound, acceleration (gravity, oscillations), weight, and forces or displacements otherwise applied. It is possible to have small and cost-effective embodiments which deliver signals exactly proportional to the measured variables. The effects of ageing and temperature and other disturbing influences can be effectively compensated. A particularly interesting application would be use for measuring the very smallest air speeds, since thermal anemometers fail in principle here. The drawing shows a projection principle: the appropriately configured free fibre end retroreflects light into a specially shaped lens and is imaged as a square light spot on a field of four photosensors. <IMAGE>

Patent DE-3217390-A1 (DE)
Title: Metal pieces of a shape suitable for placing in the mouth, such as, for example, metal discs, for eliminating or improving deficiency states and for detoxication
Inventor: PICKEL HANS
IPC: A61K33/24
Filed: 1982-05-08
Abstract: In the elimination of deficiency states relating to metals, it is possible to place metal pieces in the mouth, in place of tablets, which is advantageous inasmuch as it is possible thereby to achieve a result over a longer period with, in fact, a lower dosage. Thus there is no unwanted or disadvantageous inundation of the body, which is often the case on intake of tablets. Metal pieces made of aluminium have a detoxifying effect for the period during which one such is placed in the mouth.

Title: Process for the structural isomerisation of n-alkenes, catalysts for carrying out this process and process for preparing this catalyst
Inventor: SCHLEPPINGHOFF BERNHARD DR
IPC: B01J21/04
Filed: 1982-07-24
Abstract: n-Alkenes can be converted into the respective i-alkenes by structural isomerisation, by treating these n-alkenes or hydrocarbon streams containing such n-alkenes at a temperature from 300 to 550 DEG C and a pressure from 100 bar to 10 bar over a catalyst which consists of a  gamma -Al2O3 having a purity of at least 99.5% by weight and an SiO2 doping of between 0.05 and 0.5% by weight, relative to the quantity of the undoped  gamma -Al2O3. Hydrogen can be added to the hydrocarbon feedstream in an H2/n-alkenes molar ratio of 0.5-10 : 1. The catalyst can be prepared by treating a  gamma -Al2O3 with a solution of a tetraalkyl orthosilicate, which can be decomposed at an elevated temperature, in an inert solvent, followed by evaporation of the solvent and thermal decomposition of the tetraalkyl orthosilicate.

For facilitated production with increased spring comfort, the invention proposes that a top unit (1), consisting of individual, interconnected conical springs, and a similar bottom unit (2) (the springs (5, 9) of both units being arranged spaced apart relative to one another) be joined together in such a way that the conical springs (5, 9), directed with their taper towards the centre, overlap in the central region and, at that point, are connected to one another by straps (8, 11) extending in an undulating manner and lying in a crossover manner relative to one another. <IMAGE>
Patent DE-3236906-A1 (DE)
Title: Plate heat exchanger
Inventor: MEIKE KLAUS
IPC: F28D1/03
Filed: 1982-10-06
Abstract: The plate heat exchanger (P) is composed of two metal sheets (1, 2), between which is arranged a cavity. On opposite sides of the plate heat exchanger (5) extend collecting channels (10) which communicate with the cavity. One (1) of the metal sheets (1, 2) is essentially plane, whereas the other sheet (2) has bosses (6) formed by embossing and welded to the plane sheet (1). The plate heat exchanger (P) can be produced cheaply, since the sheets (1, 2) have to be deformed only slightly. The heat contained in a heat-exchange medium flowing between the sheets (1, 2) can arrive at the plate surface (5) over the shortest possible distance, because heat conduction need take place only over the thickness of the sheets (1, 2). The plate heat exchanger (P) is suitable as a heating body. <IMAGE>

Title: Door
Inventor: SOMMER HORST
IPC: E06B5/16
Filed: 1983-02-10
Abstract: A door, in particular safety door with fireproof and airtight properties, has a number of shells, at least one shell of which bears seals which are brought into contact with the frame when the door is closed. Locking bolts arranged in a locking box are brought into a first locking position by a trip device when the door is closed and, by actuation of a handwheel or the like, into a second locking position, in which the door is pressed against the frame, the seals ensuring an airtight closure in relation to the frame. According to a preferred embodiment, the handwheel only acts on the locking bolts when these are automatically brought into their first locking position by the trip device so that, by actuating the handwheel, the locking bolts are brought further in the direction towards the frame into the second locking position, in which the door is pressed against the frame with the seals. In a further embodiment, the bolt is extended automatically, as soon as the door assumes its closed position, and locks the door in relation to the frame in such a manner that the seals ensure an airtight closure between the door and the frame.
