Title: Mobile hydraulic excavator - lifting mechanism with overload warning and cut off switches
Inventor: PICK HEINO
IPC: B66C23/90
Filed: 1973-08-31
Abstract: The excavator articulated arm carries at its free end a load measuring dynamometer. The articulated arm on the machine body carries an angle measurement instrument. The hydraulic lifting cylinder has a pressure gauge. These measuring instruments are connected to a pre-programmed computer unit which is connected to the warning signal and cutting off switching system. The computer system evaluates the allowable limiting values for the given load and angle settings and it evaluates the limiting pressure for the lifting cylinder. When this pressure is exceeded then a warning signal is produced and the switching off device will respond. In addition to the above measuring instruments a measuring instrument senses the longitudinal and transverse arrangement of the vehicle undercarriage and this information is fed into the computer. This arrangement ensures that the full capacity of the excavator is utilised.

Title: Identifying-characterising liquid samples - by mixing with radionuclide mixts. and processing spectrum emitted
Inventor: RASSOW GOETZ DIPL PHYS
IPC: G21H5/02
Filed: 1973-11-21
Abstract: Characterisation of liquid samples e.g. in clinical chemical and nuclear medical laboratories, is carried out by mixing each sample with a number of radionuclides, the energy spectrum of the radiation emitted by the sample being processed for the determination of the sample characteristic. Method associates the identification with the sample and not with the vessel contg. it, so that the sample may be subdivided as often as desired. The quantity of radionuclides added is too small to effect any of the analyses carried out. The process can be extended to include radioactive samples, provided an entirely different energy spectrum is used for sample identification to that arising from the sample itself.

Title: Flexible elastic sheet collector mechanism - has guide bent away from stack at first transporter and parallel at second
Inventor: SCHAEL RUDI
IPC: B65H29/22
Filed: 1974-01-18
Abstract: The mechanism is particularly for use in microfilm handling machine, having a first transporter delivering the sheet to a stack, and a second one conveying them to a final position, also a movable supporting base and a pressure plate for the stack. A guide is provided for the sheets delivered by the first transporter to the stack. In the vicinity of the first transporter this is bent away from the stack, and in that of the second one it runs parallel to the last sheet in the stack.

Title: Exhaust gas removal system for motor vehicle engine - has vacuum generating conical shell assembly at its outlet end
Inventor: KOVACS OSKOLAS ANDRAS
IPC: F23L17/02
Filed: 1974-03-05
Abstract: The vacuum generating conical shell and cylinder assembly is fitted on the outlet end of the motor vehicle engine exhaust pipe. This arrangement generates vacuum over the whole range of engine performance varying from idling to full load. The vacuum generating arrangement for promoting exhaust gas flow is fitted on the free end of the exhaust pipe so that the assembly can be readily detached, and has a cylinder which is pushed on the exhaust pipe end. This cylindrical section is joined to a flared conical section which supports an outside, enveloping cylinder with radial pins. The flared section envelopes a truncated conical shell and the direct flow path is blocked by a conical, dished plate whose apex faces the flow direction. Exhaust gases escape through circumferential slots between conical sections into the space within the enveloping open ended cylinder. Exhaust gases are emitted with low noise because pulsations are damped out.

Title: Sealing ring with two sealing surfaces - has flexible lip attached to close-fitting rigid element
Inventor: ROSENTHAL ERICH
IPC: F16J15/3204
Filed: 1974-09-27
Abstract: A sealing ring (1) is intended to retain the lubricant in the bearing of a rotating shaft, is of generally rectangular cross-section with an annular groove (5) surrounding a cylindrical wall (2) terminating in a lip (3). The inside diameter of the lip (3) is somewhat smaller than the diameter of the shaft on which the seal is to be fitted so that when the seal is installed the lip (3) exerts a pressure on the shaft surface. This pressure is increased by venting the space (6) behind the lip to atmosphere through the hole (7). In some applications an intermediate pressure controlled by a valve is applied to the annular space (6).

Title: Prodn. of natural gas substitutes from coal, tars and heavy oils - by gasifcn. and methanation, using indirectly gas-cooled catalyst in final stage
Inventor: MUELLER WOLF-DIETER DIPL ING
IPC: C10L3/08
Filed: 1974-07-27
Abstract: Multi-stage metharisation of gas mixts contg. H2, CO and CO2 from gasifcn. of coal, tars or heavy oils, using Ni catalysts under 5-100 bar at 200-500 degrees C, in which the final methanisation stage is carried out on a catalyst indirectly cooled by gas, in countercurrent to the product gas. Used for production of natural gas substitutes with high methane and low hydrogen contents. The final dry methrisation stage, which requires the gas to be re-heated after cooling to condense water, is eliminated. Pressure drop in the system is reduced, so that the product gas is delivered at higher pressure which favours the washing-out of CO2 and feeding into the supply mains. Initial gasifcn. processes can be operated at lower pressure, reducing the energy required for compressing the oxygen and steam used.

Title: Telephone network with high traffic loading - operates by constructing inter-exchange connections in both directions and retaining best correction path
Inventor: BRANDSTETTER ALOIS DIPL ING
IPC: H04Q3/00
Filed: 1975-07-25
Abstract: The telephone network has its traffic loading increased by avoiding certain limiting conditions as regards the direction in which a connection can be made. Connections between a calling and called exchange are made via the best connection path chosen by taking into account not only lines from calling to called exchange but also lines in the opposite direction from called to calling. A connection is first made in one direction from the calling to the called exchange. The called exchange then makes a connection in the opposite direction back to the calling exchange, using the usual criteria for call rerouting. The two connections are then compared in terms of line length and section criteria and the better of the two is chosen.
