Title: Method of making controlled release products for chewing gum
IPC: A23G4/20
Filed: 1987-12-15
Granted: 1992-01-22
Abstract: A process is disclosed wherein an ingredient is treated so that it will exhibit a controlled release when incorporated in chewing gum. According to the method, a quantity of a powdered ingredient is mixed with an agglomerating agent, such as a modified cellulose, and a limited quantity of a solvent for the agglomerating agent, such as water. The quantity of solvent is limited so as to produce a mixture which is only moist or damp. This damp mixture is characterized as being dust-free, non-flowing and crumbly. The damp mixture is then dried and the dried mixture is treated, e.g. by grinding and/or screening, to produce the desired particle size range in the agglomerated ingredient particles. These agglomerated particles comprise collections or clusters of ingredient particles which have been bound together by the agglomerating agent.

Patent EP-0236051-B1 (EP)
IPC: H03K17/972
Filed: 1987-02-24
Granted: 1991-09-18
Abstract: The present disclosure describes circuit variants for reducing electromagnetic interference from saturable core keyboards to acceptable levels. The invention finds particular application in conjunction with capacitive-discharge scan techniques used in such keyboards. In order to attenuate the external field resulting from such techniques, a circuit is taught which effectively disconnects the scan line array from the capacitor charging circuit during the time between scans. A second variant, when added to the first, further reduces interference by disconnecting the entire scan circuit from the supply potential during the scan time thereby eliminating steady-state currents and turnoff oscillatory transients.

Date Nov. 3, 1988.Especially in gripper, insertion and bending tools of automatic insertion machines for electric components, the problem arises, that the production flow is adversely influenced because of solder accumulations at the tools. In machine design it is already known to apply hard material layers on a nitride base to improve tool surfaces; normally, better solder resistance is expected of them. According to the invention at least one second layer is provided as the cover layer with solid-lubricant properties, besides the nitride base layer. The base layer has here preferably a gradual change from high density in the boundary region to the base material of the tool to a porous rough structure at the boundary surface to the cover layer, where the change of the density can be continuous. The metal-nitride layer is advantageously a titanium nitride. With such coatings, the service life of the tools can be increased by more than one order of magnitude.

Abstract: This invention relates to a process for amplifying a specific nucleic acid sequence. The process involves synthesizing single-stranded RNA, single-stranded DNA and double-stranded DNA. The single-stranded RNA is a first template for a first primer, the single-stranded DNA is a second template for a second primer, and the double stranded DNA is a third template for synthesis of a plurality of copies of the first template. A sequence of the first primer or the second primer is complementary to a sequence of the specific nucleic acid and a sequence of the first primer or the second primer is homologous to a sequence of the specific nucleic acid. The amplification process may be used to increase the quantity of the specific nucleic acid sequence to allow detection, or to increase the purity of the specific nucleic acid sequence as a substitute for conventional cloning methodology.

Granted: 1992-03-04
Abstract: In a disc concentrator used for the dehydration of suspensions, with axially spaced suspension chambers and filtrate chambers which are open towards a stationary trough and are mutually separated by rotatable screen filter discs, the individual filtrate chambers are divided by radially and axially extending transverse walls into individual filtrate chamber sections which are distributed around the periphery and preferably sealed from one another. In addition, the filtrate outlet on the bottom side of each filtrate chamber is divided into at least two mutually separate filtrate outlet sections on the outlet side, which are arranged one after the other in the peripheral direction of the trough, for filtrate of varying purity. In conjunction with the individual outlet sections, the transverse walls ensure effective filtrate separation. In addition, the outlet sections can also be subjected to vacuum, in order to accelerate the dehydration process. <IMAGE>

Abstract: The invention relates to a method and apparatus for sand molding composite articles formed of a light alloy metal and fibrous insert. A sand mold is formed containing a fibrous preform separated from the walls of the mold cavity. The mold is fed by means of a tube dipping into a liquid metallic bath therebelow. In the molding process, the pressure in the mold cavity and above the bath are reduced, and the pressure above the bath is increased to create a positive pressure differential  DELTA P, thereby forcing molten metal from the bath into the mold cavity. The pressure in the mold cavity and above the bath are then increased to above atmospheric, and the pressure differential  DELTA P is maintained until the metal in the mold cavity solidifies.
