Patent DE-2222219-A1 (DE)
Title: Compressor shaft seal - with carbon ring sec seal shielded from corrosive fluid
Inventor: POTTHARST JUN JOHN E
IPC: F04D29/12
Filed: 1972-05-05
Abstract: Compressor for a corrosive fluid, e.g. salt water steam, has a shaft seal preventing escape of the compressed fluid from the compressor housing; this seal comprises a first ring sealed to and rotating with the shaft, a radial plane of this seal running in sliding contact with a non-rotating, but axially slidable carbon ring which is mounted in a generally C-shaped housing fixed in the wall of the compressor casing; this carbon ring is urged by a spring in an axial direction to bear against the surface of the first sealing ring. The housing also contains, radially inside and spaced away from the carbon ring, an inner wall in the form of an annular strip surrounding the shaft but constituting a small gap between itself and the shaft through which the compressed fluid can flow. Between the radially inner surface of the carbon ring and the radially outer surface of the annular strip a second seal is formed by an elastic sealing ring, pref. an O-ring having a coeffic. of friction equivalent to PTFE, which is prevented from moving axially relative to the annular strip by fixing means, pref. shoulders. Thus, as the end surface of the carbon ring wears, areas of the radially inwards surface of this carbon ring which have not been in contact with the fluid slide over the outer surface of the O-ring or equivalent. This arrangement ensures improved performance of the S-ring seal, since the carbon surface with which it is in contact has not yet been in contact with the corrosive fluid.

Title: Defatting starch-rich vegetable materials - using inert gas in hypercritical state as extracting agent
Inventor: SCHWENGERS DIETER DIPL CHEM DR
IPC: C11B1/10
Filed: 1972-11-14
Abstract: Crushed plant material rich in starch is defatted by extracting it with an inert gas in the hypercritical state or with a liquified inert gas at a pressure of more than the critical pressure of the gas, and recovering the extracted material by raising the temp. or reducing the pressure of the gas in the hypercritical state. Extraction may be carried out e.g., at 20-100 degrees C and 30-1000 atm. using ethane, propane, SO2, CO2, ethylene, halogenated hydrocarbons, etc. The process is esp. useful for degreasing cereals such as maize, wheat, barley, oats, etc. The resulting fat-free starch can be recovered or converted into glucose with starch-degrading enzymes.

Title: Maximum sweep windscreen wiper - with pivoted blade on arm between stops and tilting to lie along edge of windscreen
Inventor: SEIBICKE HORST
IPC: B60S1/34

Title: Logical network for stored data failure correction - uses redundant code to correct bit failures in integrated circuit network
Inventor: ENZMANN WERNER DIPL ING
IPC: G06F11/18
Filed: 1974-04-23
Abstract: A logic network for correcting bit failures in stored binary data uses only one decoding network. The information is held in a register in a highly redundant code which is used to detect and correct any errors when the data is read out. A closed loop network with suitable logic properties reconstitutes the data correctly. With a sufficiently redundant code, the information may be corrected even if several bits have become corrupted. A suitable code for this purpose is briefly described, and consists of digital words built up from test characters. A voting system is used so that faulty readings may be rejected.

Title: Support frame for track rollers - is pivoted on support arms to prevent tracks from splaying
Inventor: REICH WOLFGANG
IPC: B62D55/084
Filed: 1974-07-15
Abstract: The rear of the tracked vehicle is fitted with a drive axle at the ends of which are fitted the drive wheels. The lateral support frame for supporting the track rollers are hinged about the rear end of the vehicle on rigid axles attached to the drive axle. Further support is by means of lateral struts which are hinged about longitudinal axes on the chassis and the frame. The bearings have limited slip movement so that the frame is pivoted about the drive axis in vertical planes. This prevents the tracks from splaying outwards when subjected to lateral forces.

Title: Method of assessing viability of seeds - involves passing electrical current through partially germinated seed
Inventor: LEVENGOOD WILLIAM C
IPC: A01C1/02
Filed: 1974-09-13
Abstract: The method is for assessing the viability of seeds, such as peas. It is particularly related to giving results applicable to growing in open ground. Dry seeds are kept moistened for a period of time and at a temperature which allows them to pass into the first phase of their germination cycle, but without starting the final phase. An electric current, at a constant voltage, is passed through each seed and measured and the seeds separated into groups according to the observed current values; the viability being related to current flow. The max. current and voltage required are about 40 mu A and 1.5V respectively.
