Title: Electromagnetically compensated beam balance - provides two compensation ranges using two groups of large and small weights
Inventor: KNOTHE ERICH
IPC: G01G7/04
Filed: 1978-09-27
Abstract: A beam balance, esp. for analysis, with electromagnetic compensation, has a fixed counter wt. on the beam and a wt. switch arrangement on the side of the load sensor for compensation expansion. The wt. switching is semi or fully automatic, enabling rapid closing or weighing out and can be used with dual range balances. The wt. switches consist of two groups each operated via a shaft by cams. One group is motor driven and controlled by a sensor between the side pan and the load pick-up whilst the other group is activated by over or under load signals from the compensator. Alternatively, both groups are motor driven. For the course compensation operation mode only the larger wt. group is used.

Title: Silver roller drawing unit - has a blade to prevent build-up on lower roller
Inventor: SCHMID REINHOLD
IPC: D01H5/60
Filed: 1978-10-23
Abstract: In a roller drawing unit for sliver, where there is at least one powered lower roller, there is a blade with a cutting edge directed approximately tangentially against the rotary direction of the lower roller. It is placed in the direct zone of the roller surface. The cutting edge of the blade is located at the opening of a suction channel, and the blade is mounted to the housing for the suction channel, so that its mounting pivots on an axis. The operating linkage for the blade mounting is triggered by a switch. There is a connection between the suction channel and a fibre collection channel, where there are fibre measurement probes linked to a fibre indicating unit. The design prevents a build-up of the sliver material on the roller surface, and there is no requirement to encapsulate the drawing unit.

Title: Pump esp. vane pump with lip seal for drive shaft - has channel which connects space behind the lip to suction side to reduce pressure on the lip
Inventor: RENNER WOLFGANG
IPC: F04C15/00
Filed: 1978-12-23
Abstract: The shaft which connects the pump rotor to the drive motor, protrudes through the pump housing in which it is supported by a plain bearing. A bush mounted over the shaft contains a lip seal. The space between the lip seal and the bearing, which supports the shaft in the housing, is connected by a channel to the suction side of the pump. The channel can be cut in the outside of the bearing bush or in the bore of the housing. The channel relieves the pressure on the lip seal and increases its life.

Title: Aq. paper sizing agents - by quaternising a basic amide of a fatty acid and a poly:alkylene poly:amine with epichlorohydrin
Inventor: BONIN WULF VON DR
IPC: D21H17/55
Filed: 1978-12-30
Abstract: Paper sizing agents are made by quaternising an average dibasic amide of (a) fatty acids with a m.pt. of >30 degrees C and (b) amines of formula H2N-R-(NH-R')n-NH2 and/or commercial mixts. of these in which R and R' are 2-3C alkylene and n = 1-6. The amine mixt. may contain up to 80 wt.% impurities consisting of cyclic and/or branched amines having the same boiling range. The amide is quaternised with 0.5-1 equiv. (on amino gp. in the basic amide) of epichlorohydrin in the presence of water. The prod. may be diluted to the desired solids content with water as desired. The prods. have improved bulk sizing properties on paper. Technical amine mixts. can be used avoiding the necessity for isolating the linear amine form the amine mixt. before making the amide. Addn. of electrolytes such as NaCl to the prepn. give prods. with a reduced viscosity at a given concn., which improves handling without adversely affecting the performance.
Patent DE-2901084-A1 (DE)
Title: Inflatable sole for sports shoes - has foam bodies between transverse webs preventing bulges and ensuring even pressure distribution
Inventor: BRITSCHINN HORST
IPC: A43B17/03
Filed: 1979-01-12
Abstract: Transverse webs are used which have a number of openings. The webs run between the top and bottom sides of the inflatable sole member while foam pieces (13) are connected between the webs to the top and bottom sides (2). The foam bodies pref. fill up the spaces between the transverse webs and can be stuck to the top and bottom sides. By filling up the entire pressure chambers the top and bottom sides can be held at a defined distance from each other over their entire surface so that no curving or bulging can occur. A very even smooth surface is thus obtained so that the pressure exerted when running or walking is distributed over the entire face.

Title: Mains-frequency interference suppressor for heart signals - uses common mode rejection with delay circuit synchronised to mains
Inventor: NETTELHORST HERWIG FRHR VON DR
IPC: H04B15/04

Filed: 1979-12-29
Abstract: The present invention relates to a process for the manufacture of desulfurizing agents containing 1-6% by weight of chemically bonded water, based on calcium oxide-containing calcium carbide, for crude iron and steel melts. To this end, a molten mixture of calcium carbide and calcium oxide with a CaO content of 20 to 80% by weight is produced, which is allowed to solidify into a block. Next, the block which still has an average temperature of more than 400 DEG C., is rough-crushed to particles with a size of less than 150 mm and calcium oxide is added to the comminuted mixture, which still has a temperature of at least 400 DEG  C., in accordance with the CaO content desired in the end product. The mixture is finally ground in the presence of air or nitrogen with a moisture content of from 5 to 20 g/m3 (at 1.013 bar and 273.15 K) at temperatures below 100 DEG  C. to particles with a size of less than 10 mm.
