Patent DE-2422791-A1 (DE)
Title: Cutter feed system for spline cutting - compensates automatically for wear of single point tool by stylus actuation
Inventor: KIFFE HORST-GREGOR
IPC: B23D3/02
Filed: 1974-05-10
Abstract: The single point is connected to a system which senses the actual position of the cutter, and this system adjusts the cutter automatically to compensate for the wear of this cutter. The single point cutter is drawn in a holder through the workpiece bore and such a cutter is more flexible in application than a multi tooth broaching cutter. The machine tool has a dial gauge whose stylus is inthe path of the cutter edge. The displacement of the gauge is used for producing correction of the cutter position. The stylus can be inductively coupled to a cutter adjusting mechanism motor. The stylus senses the extent of the wear and it can actuate a microswitch in turn connected to the correction mechanism.

Title: Address-free defect locating system for PCM transmission parts - has unmanned repeaters and three signals closing and opening test loops sequentially
Inventor: SCHEFFLER HARTMUT
IPC: H04B17/40
Filed: 1974-05-25
Abstract: The address-free defect locating system for PCM transmission paths with unmanned intermediate stations produces a first signal by briefly interrupting the remote supply voltage. This first signal closes the defect locating loop in each intermediate station, whilst a second signal switches on the amplifier in the first intermediate station. A third signal is then transmitted over the now closed defect locating loop and back to its receiver, where it is evaluated. The second signal is again transmitted to break the tested intermediate station defect locating loop and to switch on the amplifier in the next intermediate station. The third signal is then retransmitted, and so on.

Title: Water-proof communication cable - with plastics-insulated strands and interposed sealant
Inventor: DAGEFOERDE HANS-GERD DIPL ING
IPC: H01B7/285
Filed: 1974-06-19
Abstract: A waterproof communication cable comprises plastics-insulated strands and a sealant in the interstices between the strands. The sealant consists of a foamable matl. whose expansion in the interstices is effected after the cable has been spun, the time of the foaming step being chosen at any time as desired. Prior-art polyurethane sealant requires foaming before the spinning step involving the risk of excessive mechanical stresses on the plastics insulators during mfr., leading to possible damage. The alternative use of petrojelly may adversely affect the dielectric characteristics of the insulation as the jelly may penetrate into the plastics.

Title: Disintegrator for elastic waste, esp. foam and tyres - pressing shaft for stripper rings ejects cuttings more quickly
Inventor: LANGENSCHEIDT ERNST
IPC: B26D1/38
Filed: 1974-08-16
Abstract: In the parent patent a shearing machine for cutting up elastic matls., esp. waste foam, with two intermeshing cutting cylinders, comprises a series of cutter discs keyed on shafts driven in opposite directions and positioned relatively to the cutter discs of the other shaft by spacer collars on which stripper rings are supported with radial play; the inside dia. of the stripper ring being larger than the outside dia. of the spacer, whilst the outside dia. of the stripper is equal at least to that of te cutter discs. The strippers thus turn continuously enabling elastic matls. to be chopped up small and ejected from between the cutter discs without the possibility of fragments being trapped behind the strippers. In the patent of addn. at least in the case of the upper cutting cylinder and for pref. in that of the lower cutting cylinder also, there is a roller exerting pressure on the stripper rings in the direction in which the cutting action takes place. Roller is carried in adjustable bearings permitting its point of contact with the circumference of the stripper rings to be altered. A line drawn from the centre of the roller to the centre point of the nip between the cutting cylinders, subtends a predetermined angle alpha which locates the line of intersection of the stripper rings and the cutter discs nearer to or farther from the nip.

Title: Exhaust gas purifier for IC engines - has compressor for delivering combustion air to purifier heat exchanger
Inventor: KATABUCHI KEICHI
IPC: F01N3/26
Filed: 1975-03-15
Abstract: The exhaust gas purifier is used especially in motor vehicles. The power of the engine is maintained at its highest level while reducing toxic substances below the required level. The air is drawn into the engine system through an air filter from which air is supplied to the carburettor and the heat exchanger. A compressor and air flow regulator are connected to the pipes connecting the filter to the heat exchanger. The engine exhaust is connected to the heat exchanger primary side and nitrogen oxides are decomposed within the heat exchanger header chamber into which air is pumped by the compressor. The exhaust gas and air mixture flows subsequently into the exchanger secondary side through a connecting pipe and from there to the exhaust pipe for disposal. Surface combustion of exhaust gases takes place with the secondary side and exhaust gases are completely burned.

Abstract: The polyps share is used in conjunction with an endoscope for the removal of clusters of polyps (within the stomach). A rubber finger stall is fixed to one of the biopsy forceps by a thread of surgical silk drawn through the instrument channel. Once the tip of the instrument is position in the pyloric region the finger stall is brought in view by pulling on the outer thread end and then the finger stall is inflated by blowing air into it, permitting several polyps to be consecutively sucked into the snare using a suction tube, ecraseur or forceps without repeated removal and repositioning of the instrument to collect polyps singly.

Title: Detoxication of tobacco, cigars and cigarettes - by adding materials which generate catalysts to lower toxic material content on burning
Inventor: BRANTL VICTOR
IPC: A24B15/28
Filed: 1975-06-06
Abstract: Detoxication of tobacco, cigars and/or cigarettes takes place by adding matls. which, on burning, generate an adequate quantity of a catalyst to lower the content of toxic matls. in combustion gas and in smoke. The matls. may be converted to such a catalyst and/or are the catalysts and are activated on burning the tobacco. The matls. added form a catalyst in the flame-zone and/or through the hot combustion gases. Active catalyst formation may take place through structural changes, decompsn., phase-conversions, solid body reactions of >=2 components. Catalyst is highly active. Catalyst is present at different temps. depending on position and distance from combustion zone. Catalyst is not poisoned. Detoxication extends to environment. Unstable catalysts may also be used. CO can be converted to CO2 and NO to N2. Catalyst also acts by adsorption and/or absorption, e.g., to reduce nicotine content. The catalyst-forming matls. contain main or side-gp. metals or cpds., pref. Ti, V, Cr, Mn, Fe, Co, Ni, Cu and/or Zn. In an example, addn. of 5% Pb nitrate to tobacco, lowered CO content of waste gas to 42% and NO content to 58% of quantities in untreated tobacco smoke.
