Title: Defoamer for yeast fermentation
Inventor: SCHMID KARL DR
IPC: C12N1/16
Filed: 1984-12-06
Granted: 1988-06-09
Abstract: Troublesome foaming in the fermentation of yeast is suppressed by the addition of polyglycol ethers which are derived from saturated and monounsaturated C16-C18 fatty alcohols and which contain on an average of from 1 to 4 ethylene and/or propylene glycol ether groups. Preferred defoamers contain oleyl and cetyl alcohol residues in a ratio of from 3:1 to 1:1, and on average 2 ethylene glycol ether groups. The defoamers do not inhibit yeast growth or lead to premature softening and liquefaction of the compressed yeast.

Title: Improvements in baby feed bottles
Inventor: ATKIN EDWARD
IPC: A61J9/00
Filed: 1984-10-18
Granted: 1989-11-23
Abstract: The invention provides a baby feed bottle and combination thereof with a screw fitting annular cap to which a teat, preferably moulded of liquid silicone rubber may be assembled before the cap is fitted to the bottle. The bottle is dimensioned with a large capacity per cm height, giving it an unusually large diameter, and the externally threaded neck (12) in particularly wide mouthed as it also has a large diameter of the order of three-quarters the diameter of the main portion (10) of the bottle. The teat is moulded with shape and dimensions such that, when the annular captteat sub-assembly is fitted to the bottle and screwed down, a flap valve arrangement is produced by a depending lip (35) on the teat which seals against the interior of the bottle neck. The flap valve arrangement is operative when the bottle is used to prevent collapse of the teat mouthpiece.

Title: Process for manufacturing valve seat rings
Inventor: KOHLER MICHAEL DIPL ING
IPC: B22F5/00
Filed: 1985-04-03
Granted: 1987-12-17
Abstract: A process for the production of valve seat rings by powder metallurgy wherein molybdenum disulfide in the range of about 0.5% to 1.5% by weight is added to a powder mixture containing 0.8% to 1.5% by weight graphite, 1.0% to 4% by weight lead, 0.5% to 5% by weight nickel, 1.2% to 1.8% by weight molybdenum, 9.6% to 14.4% by weight cobalt, and the remainder iron. The resulting powder mixture is pressed into valve seat rings at a pressing force between 40 and 60 and preferably 50 KN/cm2. The rings are then sintered in a neutral atmosphere at a temperature of 1100 DEG  C. to 1200 DEG  C., finally compressed at a pressing force above 120 KN/cm2 and heat-treated if required. The resulting valve seat rings have greatly improved wear properties when used in internal combustion engines using lead-free gasoline.

Abstract: The security method uses a real-time-controlled coding system during the period when connection is being established. A time base coding system is used, with a timing mode which uses a time period which is a multiple of that used during message transmission. In addition to repeated changeover of the time bases code signals, calling information is transmitted which includes a coded address, and also starting information for changeover from the long time base to the short time base. The calling information contains further time information in addition to the coded address. The reversal period for the calling information is the same as that for the coded signals with the short time base.

Abstract: A memory is described which incorporates redundancy in the form of one or more redundant columns. An applied binary address is first distributed between predecoders which form a 1-out-of-2<n> code from n bits received. For each non-redundant column there is available a part of a main decoder, each part receiving a different combination of the bits supplied by the predecoders, thus selecting the column. For each redundant column there is provided a redundancy decoder. The latter decoder receives all bits supplied by the predecoders, each time via a series connection of a activatable gating element and a fuse element. Per predecoder the outputs of the series connections are combined in a wired logic function. Each wired logic function forms an input signal of the actual redundancy decoder. When a redundant column is to be addressed, all fuse elements but one of a group are opened and the gating elements are activated. A memory column to be replaced is then uncoupled by way of another fuse element.
