Title: Adjusting device for the grinding and polishing of different workpiece diameters in the centreless method
Inventor: RAMRATH WALTER MATTHIAS VERSTO
IPC: B24B5/22
Filed: 1982-01-26
Abstract: The invention relates to a central diameter-adjusting device in single-position or multi-position centreless grinding and polishing machines. The device enables the work guide to be changed over from one particular workpiece diameter to another particular workpiece diameter in such a way that, by mechanical linking of the work-rest vertical adjustment with the horizontal infeed of the control feed wheels, an integrated and simultaneous variation of the vertical level of the work rest on the one hand and of the horizontal infeed of the control wheels on the other hand is effected. An exemplary embodiment of the invention is shown in drawing 28358/1. The work-rest vertical adjustment (15, 16) is here linked to the feed unit (3, 9, 10, 11, 12) via a rolling guide (13, 14) and two parallel round guides (8). <IMAGE>

Title: Electrical machine which can be supplied via a converter and whose speed can be regulated
Inventor: LEITGEB WILHELM DR
IPC: H02K1/27
Filed: 1982-02-11
Abstract: The invention relates to an electrical machine which is supplied via a converter and whose speed can be regulated, having a rotor (4) and having a stator laminate stack (2) which supports the stator winding (3) which is connected to the converter. As a rule, the converter voltage consists of a mean value on which a voltage is superimposed whose frequency is high in comparison with the rotation frequency of the machine. In order to limit the current losses caused by this high-frequency voltage using simple means provided in the machine itself, it is proposed that the rotor (4) be dimensioned to have a shorter axial length than the stator laminate stack (2) and that there be arranged in the intermediate space produced as a result of this shorter length of the rotor (4) an unslotted, annular yoke (6), which is laminated in the axial direction and is separated from both the rotor (4) and the stator laminate stack (2) by a non-magnetic intermediate layer (9 and 10). <IMAGE>

Patent DE-3205810-A1 (DE)
Title: Process and device for treating the exhaust gases from internal combustion engines
Inventor: VIRK KASHMIR SINGH
IPC: F01N3/28
Filed: 1982-02-18
Abstract: In a process and device for filtering combustible particles out of an exhaust gas stream and for periodic regeneration of the filter bed and the catalyst part thereof by combustion of the retained particles, a part of an exhaust gas stream is heated upstream of the filter, so that the catalyst temperature is raised above that at which the catalyst can initiate the combustion of the particles. A small quantity of additional fuel is injected into the exhaust gas stream, before the latter enters the catalyst part, so that the heated fuel/exhaust gas mixture ignites. After the initiation of the oxidation reaction, the further supply of preheating energy to raise the exhaust gas temperature to the initiation temperature of the catalyst can be stopped without thus impairing the combustion rate of the combustible particles. Preferably, the additional fuel is brought into heat transfer contact with the filter, so that the fuel is heated before it is injected into the exhaust gas stream. In this way, a controlled carbon removal rate from the exhaust gas stream is achievable without damaging the filter by temperature changes.
Patent DE-3206686-A1 (DE)
Title: Percussion drilling rig
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: E21B4/16
Filed: 1982-02-25
Abstract: A pneumatic percussion drilling system is described which is operated from a liquid-air cylinder on the drill. The rotary drive is used for the translation of the drill bit on the one hand and for the rotary drilling in hard rock on the other hand. The percussion is taken from a distributor head of the distributor shaft with or without a step-up or step-down of the rotational speed of the drill head and can therefore have a relatively low percussion rate despite the high operating pressures. Rotary breakdowns of the drill head are largely avoided with the use of an inertial gyroscopic drive of the head, and it becomes clear that the useful system combination of inertial-mechanical rotary drive with pneumatic percussion operation results in drilling which is also fully manoeuvrable in optimum manner in the bore hole with commands "rope slacken (drilling)" and "rope tighten (drilling pause)" and in which only the rope needs to be subsequently guided into the bore hole, and the bore hole, like the implements, is resistant with cold exhaust air against high earth temperatures. Here, the cylinder air is used not only on the percussion mechanism but also on the gyroscopic drive by means of a compressed-air turbine, and in fact in a tubeless manner, for which there is no alternative at great depths.
Patent DE-3208053-A1 (DE)
Title: Orientation device
Inventor: SAXON JOHN WILLIAM CHARLES
IPC: B65G47/14
Filed: 1982-03-05
Abstract: A device for orientating parts which each comprise an axial elongated body which extends on opposite sides of a flange at different distances is proposed. Different parts can have their centre of gravity on different sides of the flange. The device comprises a slotted guideway, along which parts are conveyed by vibration, the slot being too narrow to let the flange through. One part is carried on the guideway by its flange about which it can turn whilst it is situated on a first section (28) of the guideway. A second section (29) of the guideway can be entered only by such a part which is aligned at right angles to the guideway and projects with its longer section into the slot. The orientation device comprises two air nozzles (38 and 39), in each case one of the air nozzles being arranged in each case above one section of the guideway, and the two air nozzles being arranged along the guideway at a distance slightly greater than the length of an individual part. A part located on the guideway with its flange at the end of the first section (28) close to the second section (29) can be under the action of one of the air nozzles only with its longer section, so that the longer section is forced into the slot and the part into an orientation in which it can enter the second section (29) of the guideway. <IMAGE>
Patent DE-3208183-A1 (DE)
Title: Door handle for doors of motor vehicles
Inventor: SCHOEPFER OTTO
IPC: E05B17/00
Filed: 1982-03-06
Abstract: The electrical heating device in the door lock of a motor vehicle must be capable of being switched on from outside in order to thaw out the frozen door lock. Mechanical switch contacts permanently installed for this in the door lock or on the motor vehicle have the disadvantage that the heating device is switched on continuously as a result of an improper jamming of the switch contact and consequently the battery of the motor vehicle is drained. Switch contacts, in which a simple jamming is impossible, for example those which are actuated by a permanent magnet, or electronic switching devices have the disadvantage of a high technical outlay. To reduce the risk of an improper switch-on and to avoid a high technical outlay, the car key, by means of which an interrupted electrical feed line to the heating device is bridged, is used for switching on the heating device.
Patent DE-3211452-A1 (DE)
Title: Method of testing the imperviousness of ceramic hollow bodies, in particular concrete pipes
IPC: G01M3/28
Filed: 1982-03-27
Abstract: In a method of testing the imperviousness of ceramic hollow bodies, in particular concrete pipes, pressurised air is pumped into the test piece, sealed, for example, with end-mounted blank flanges, until a predetermined internal pressure is reached, and the pressure maintenance is then tested with manometers or similar measuring instruments. Since pressurised air escaping from leaky pipes does not leave any traces behind, local repairs to damaged pipes are not possible since defect points cannot be found. According to the invention, an atomisable medium which is entrained by air flowing through the defect points and deposits at the edges of the latter, thereby rendering them visible, is added to the pressurised air. Repairs can be carried out without difficulty.
