Patent DE-3123207-A1 (DE)
Title: Process for producing a regular microrelief, comprising closed depressions, on the workpiece surface, tool head and abrasive element for carrying out the process
Inventor: PROKOFIEV VALENTIN M
IPC: B24D5/06
Filed: 1981-06-11
Abstract: The process and the tools for carrying out the same are used for the grinding machining of metals. The process involves grinding workpieces by means of a rotating abrasive element (1) which acts, by means of its circumferential cutting surface, in a regularly recurring manner on the machining surface while, at the same time, the abrasive element (1) and the workpiece move relative to each other in parallel with the machining surface. The rotational plane of the abrasive element (1) essentially coincides with the direction of the abovementioned relative movement. The process can be carried out by means of a tool head with abrasive elements (1) arranged on the circumference of the carrier wheel (11) and driven by the latter via a planetary-gear mechanism, or with an abrasive element having a non-movable rotational axis, the cutting surface (24) of which comprises individual segments (25) which are arranged at a distance from one another on the circumference of the abrasive element. The invention can be predominantly used in mechanical engineering, in particular for producing oil pockets on the frictional surfaces of mountings. <IMAGE>

Title: Bidet fitting
Inventor: RETZER ROBERT
IPC: E03C1/04
Filed: 1981-11-26
Abstract: A bidet fitting is specified, which enables a conventional bathtub or a shower tray to be used in the manner of a bidet without the need for bulky parts, such as tub or tray inserts, for this purpose. A three-legged unfinished body, such as for example a T-piece, is provided with a suction or magnetic foot on one leg, a second leg is constructed with a hose connection, and situated on the third leg is a water nozzle. Commercially available T-pieces are provided with joining threads which serve for fastening the holding foot, the water nozzle and the hose connection piece. As hose connection piece, use is advantageously made of a pluggable quick coupling, which permits quick and trouble-free connection of the bidet fitting in exchange for the conventional hand spray of a shower hose. As water nozzle, a ball- joint nozzle permitting all-round adjustment of the jet direction can be chosen. The arrangement of holding foot, water nozzle and hose connection on the three legs is exchangeable, so that an upwardly directed water jet can be obtained both on attaching the bidet fitting to the tub rim and to the tub bottom. <IMAGE>

Patent DE-3200352-A1 (DE)
Title: Appliance for converting water energy into rotary motion
Inventor: KLEEN LUDWIG
IPC: F03B17/02
Filed: 1982-01-08
Abstract: The invention relates to an appliance for converting water energy into rotary motion for driving working appliances or generators. According to the invention it is proposed that weights be floated in shafts, which can be filled with and drained of water, which weights can be latched in this position on reaching the highest water level in the shaft. Once the shaft has been drained the weights are unlatched and the weight then dropping in the shaft can transmit the force thereby generated by way of suitable devices to a working appliance. For floating the weights use can preferably be made of the ocean tides.
Patent DE-3205163-A1 (DE)
Title: Ladder
Inventor: GEBHARDT KLAUS
IPC: E06C1/32
Filed: 1982-02-13
Abstract: A ladder has two climbing spars which can be arranged at an angle to one another and which are connected in their upper end region by means of a connection device. The connection device is fastened to one of the climbing spars and, for the other climbing spar, has jaws surrounding this. The jaws are displaceable relative to one another transversely in relation to the longitudinal extension of the surrounded spar. For this adjusting movement there is an eccentric bolt passing through the two jaws. This is connected fixedly in terms of rotation to a connecting strap which is itself fastened to the other climbing spar. The climbing spars can be pivoted into a parallel position and into a spread position. During this pivoting movement, an adjustment of the eccentric bolt also takes place, in such a way that, in the parallel position of the spars, the jaws are in the release position, in which the surrounded spar can be displaced longitudinally, whilst during the pivoting of the spars into the spread position the jaws move towards one another and assume the clamping position, in which the spar is held fixedly in terms of displacement.
Patent DE-3208023-A1 (DE)
Title: Mechanism having a uniformly rotating cam disc of constant thickness and constant diameter
Inventor: KUPKA MARKUS DIPL ING
IPC: F16H25/14
Filed: 1982-03-05
Abstract: The mechanism consists of a uniformly rotating cam disc of constant thickness (uniformly thick) or identical diameter as input element and a flat-faced tappet or fork rocker or roller tappet as output element. In order to improve the smooth running of such a positive cam-disc mechanism by means of suitable cam discs, or to increase the admissible maximum driving speed, the contour of the cam disc is determined by the fact that, starting from the partial paths g ( alpha ) of motion which are the target for the functioning of the drive downstream of the mechanism and are given as a function of the angle ( alpha ) of rotation of the cam disc, the law of motion of the output element is fixed such that it obeys the non-linear trigonometric polynomial <IMAGE> In this case the degree n of the polynomial is, on the one hand chosen to have a maximum so large that the spectrum of the law of motion contains only oscillation components whose frequencies are all smaller than the lowest resonant frequency of the output and, on the other hand, is chosen to have a minimum so small that the cycle of motions of the output is fulfilled with sufficient accuracy. The contour of the cam disc is determined using conventional methods, starting from the trigonometric polynomial determined in the preceding way.
Patent DE-3215534-A1 (DE)
Title: Method of determining the proportion of water vapour in a gas mixture containing oxygen
Inventor: UEDA SHINYA
IPC: G01N25/56
Filed: 1982-04-26
Abstract: In a method of determining the water vapour content of a gas mixture (test gas) containing oxygen, the water content is calculated in a simple way from the measured value of the oxygen content. The O2 content can be measured with the aid of one of the known magnetic oxygen analysers and the proportion of water vapour y in the test gas can be calculated from the linear relationship  x = a1-a2.y (% by volume), where x is the oxygen content of the test gas, a1 is the known oxygen content of a reference gas and a2 = a1/100. A logarithmic relationship results if solid-state electrolytes which conduct oxygen ions are used as O2 sensors whose principle of operation is described by the Nernst equation. The EMF corresponding to the logarithmic ratio of the partial pressures of oxygen of test gas and reference gas is functionally linked to the proportion of water vapour y in the test gas:  E = k.log (100-y), where E is the EMF corresponding to the oxygen content of the test gas and k is a constant. Application and method primarily for continuously monitoring the water content of the off-gas of industrial drying installations. <IMAGE>

Patent DE-3222424-A1 (DE)
Title: Flexible electrical cooking area for electric cookers
Inventor: RAPP JOHANN
IPC: H05B3/68
Filed: 1982-06-15
Abstract: In order significantly to reduce the power consumption by means of improved heat transmission from the cooking plate to the cooking vessel, the flexible electrical cooking area is divided into individual heating elements which match themselves by means of spring pressure to the base of the vessel and to its unevennesses. A magnet which is arranged in the centre of the flexible electrical cooking area pulls the cooking vessel, on whose bottom an iron platelet is inserted in an embedded manner for this purpose, onto the heating elements. In consequence, the cooking vessel is also prevented from sliding. Small cooking plates are superfluous in that, if they are required, only the heating elements which are arranged in the centre of the flexible electrical area are heated. Switching on of half the flexible electrical cooking area largely prevents the contents of the cooking vessel being overcooked. If a plug connection is provided, the individual heating elements can be removed and, if necessary, replaced in a simple manner. Exceptionally, if extreme contamination is expected, a protective cap of thin metal can be used, which nevertheless still allows the heating elements to be matched to the cooking vessel.
Patent DE-3223095-A1 (DE)
Title: Detachable latching connection
Inventor: AWAKOWICZ ERWIN
IPC: F16B17/00
Filed: 1982-06-21
Abstract: Latching elements (7, 10), which correspond in pairs, for the detachable connection of two parts (1, 2) have allocated to them, on one of the two parts (1), an auxiliary latch (11, 28) which, during unlatching for the purpose of releasing the connection, allows a blocking position of in each case one of the corresponding latching elements to be passed by in which the corresponding latching partners (7, 10) are held at a distance from one another until the two parts (1, 2) have separated from their connecting position. One configuration according to the invention is especially worthwhile for releasing a latching connection where a plurality of spaced-apart latching points consisting of latching elements (7, 10), which correspond in pairs, result in the common connection between two parts (1, 2) which are connected to one another, but which must be unlatched individually for releasing. The invention can be used, for example, for latching connections on housing parts of electrical apparatuses. <IMAGE>

Title: Method for controlling robots or other machines and equipment for testing components
Inventor: PRYOR TYMOTHY R
IPC: A01B69/04
Filed: 1982-11-10
Abstract: In a method for controlling robots or other machines, a pattern is visually projected into the space in the working region of the robot. A detector on a movable arm of the robot scans the pattern if the movable part is situated in the working field. The output signal of the detector is used to control the robot so that it passes through a predetermined precise path or arrives at a location in the space. As a result, a precise outer reference coordinate system for the robot is provided, which is independent of mechanical movement quantities. The position of the robot arm is thus very precise at comparatively low cost for the mechanical means for moving the robot arm. The invention therefore relates to a simple visual guidance system which is universally usable in all types of automation systems and also in coordinate measuring machines. <IMAGE>
