Title: Transcutaneous gas sensor
Inventor: DELPY DAVID THOMAS
IPC: G01N27/49
Filed: 1981-01-30
Abstract: A transcutaneous gas sensor to be applied on to the body of a patient has a sensing electrode with an exposed surface area which is placed on the body surface with interposition of an electrolyte layer, an electrolyte layer being interposed between the electrode and the body of the patient. Gas diffusing from the blood through to the body surface leads to an electrochemical reaction in the surface area. This exposed surface area may be a single, discrete surface area or several surface areas. An enveloping line surrounding the surface areas at the same time includes an area which is larger than the overall surface area, the surface areas having virtually the same widths everywhere. Alternatively, the exposed surface areas have sufficiently small width dimensions and are shaped and arranged such that the reducing zone formed by them in the electrolyte is limited to a depth of less than 1 mm for example. The gas stream to the body surface can be excited by heating the particular area examined. The stream resulting from the electrochemical reaction in the electrolyte layer is used as a measurement variable for the gas partial pressure in the blood. <IMAGE>

Title: Method and device for producing scale screens and/or scale half-tone pictures
Inventor: KIONTKE SIEGFRIED
IPC: G03C5/04
Filed: 1981-02-24
Abstract: In a method for producing scale screens and/or scale half-tone pictures, in which during the recording the grey-scale values of an imaging field are partially changed, in accordance with the object on which the invention is based the aim is to change the grey-scale values of the scale screen or of the half-tone picture in such a way that entirely novel graphic effects are achieved. This object is achieved according to the invention when during recording the imaging field (5) and the recording material (3) rotate relative to one another, and the imaging field is provided with various field sections (22, 23) having differing grey-scale values or tone densities. The outcome of this method is that a differing tone density or shading which changes radially in steps or continuously from the inside outwards is produced by the rotation over the surface of the field. Thus, it is possible using the method according to the invention to produce scale screens or scale half-tone pictures in which by contrast with the known scale screens the differences in tone density extend over the surface of the field not linearly in one direction, but circularly. <IMAGE>

Title: Balance
Inventor: PUETTER PAUL STEFAN DR RER NAT
IPC: G01G23/00
Filed: 1981-04-07
Abstract: The invention relates to a flat balance, in which the weight is applied via a movable plate to a pressure cell which is filled with gas or liquid. The internal pressure of the pressure cell is to correspond to the applied weight. For this purpose, a parallel guide of the movable plate has hitherto been necessary. In view of constructive difficulties in the building of a flat parallel guide, the parallel guide considered necessary hitherto is abandoned, and instead of it, in the event of an inclination of the movable plate, only a moment which counteracts the inclination is transmitted to the latter. The invention is to be used, above all, in order to build a portable personal balance (travel balance).
Patent DE-3115940-A1 (DE)
Title: Die-casting machine
Inventor: GOEHRING KARL DIPL ING
IPC: B22D17/30
Filed: 1981-04-22
Abstract: A description is given of a die-casting machine in which a casting chamber of variable volume is formed between the press plunger and a counter plunger lying opposite in the cylinder. Before triggering the shot, the volume of this casting chamber is reduced by appropriately controlling the movement of the two plungers such that the air which is initially still present after filling the casting chamber with liquid casting material is virtually completely displaced, i.e. a degree of filling of approximately 100% is obtained. This ideal degree of filling of the casting chamber contributes considerably to the structural quality of the shaped part obtained; in particular, the porosity and the air pockets are considerably reduced. <IMAGE>

Title: Pipeline, in particular face line for pneumatic stowing
Inventor: KUEHME ERNST DIPL ING
IPC: E21F15/08
Filed: 1981-07-09
Abstract: The invention relates to a pipeline, in particular a face line for pneumatic stowing, consisting of pneumatic stowing pipes, which can be set at an angle and have couplings at the pipe ends, and a drive for each pneumatic stowing pipe. The drive is preferably designed as a pressure-medium cylinder and produces an axial motion component for the coupling and uncoupling and in the process actuates a ratchet mechanism which enables the pneumatic stowing pipe to rotate partly about its longitudinal axis by means of elements arranged in a ring shape around the pneumatic stowing pipe and by means of a pawl. The aim of the invention is to simplify the pipeline so that a lever mechanism connecting the ends of the pneumatic stowing pipes and intended for imparting the kinetic energy from the drive to the ratchet mechanism becomes unnecessary. To this end, a connecting element (41, 42) and the fixed arrangement of the pawl (48), which has several locking pieces (53, 54) arranged around the pneumatic stowing pipe (14), are provided on a frame (8) accommodating the pneumatic stowing pipe (14), resting on pipe supports (11, 12), and provided with a bearing (23) for a fixed part (21) of the pipe drive (20), and, in the ratchet mechanism, in which the switching is effected by insertion of wedges (53, 54; 70, 71) between round cams (53a, 54a; 63, 64), the locking pieces or the elements in each case consist of the wedges or the round cams.

Patent DE-3209105-A1 (DE)
Title: Rolling mill
Inventor: MAYER ROLF DIPL ING
IPC: B21B1/42
Filed: 1982-03-12
Abstract: A rolling mill with at least two work rolls which roll on back-up rolls and are supported and drivable by means of swivelling levers on the axles of the back-up rolls is designed, in particular for the rolling down of slabs, in such a way that a small bite angle is achieved and the work rolls have a small diameter. For this purpose, the work rolls are swivelled out of the central position by means of the swivelling levers to form a larger acceptance gap. After the introduction of the rolling stock, the swivelling levers swivel back relatively rapidly in relation to the speed of rotation of the rolls. Due to the contact of work rolls with the back-up rolls, the work rolls are forced to rotate in the opposite direction to that initiated by the back-up rolls. During this process, the rolling stock is partially rolled down. After the swivelling levers have come to a halt at the end of the return movement, the work rolls rotate in the normal direction of rotation dictated by the back-up rolls and the whole of the rolling stock is rolled.
