Abstract: The present invention provides novel silyl 2-amidoacetates and silyl 3-amidopropionates which are the reaction products of azlactone and silanol reactants. The novel products result from nucleophilic addition of a soluble or insoluble, low or high molecular weight reactant containing one or more silanol groups and a soluble or insoluble, low or high molecular weight reactant containing one or more azlactone groups. The reaction products provide for high adhesion between the siliceous and azlactone reactants, as would be useful as protective coatings particularly on silicon-containing materials. It has been recognized in the present invention that silyl 2-amidoacetates and silyl 3-amidopropionates are useful linkages between silanol and azlactone derived materials.

Abstract: The problem of formulating a dentifrice which is compatible with a bis-biguanide anti-bacterial agent, for instance chlorhexidine or alexidine, is solved by using a nonionic thickening agent; a nonionic surfactant; and an abrasive which is either a sparingly soluble salt, for instance calcium carbonate, (used in combination with an agent to suppress anion formation), or an essentially insoluble compound, for instance, a silica of low anion content, or a mixture thereof. Preferably, the composition has a flavour which is mainly aniseed, balanced by mints. Preferably during the preparation of a silica containing dentifrice, chlorhexidine and saccharin are added together at an early stage, prior to the addition of silica, to avoid the formation of lumps. Such dentifrices are useful in the prophylaxis and/or treatment of periodontal disease and caries.

Abstract: Unification of a disjunctive system is performed based on context identifiers within data structures that correspond to disjunctions. Each context identifier is a logical combination of choices, with each choice identifying one of the disjuncts of a disjunction in the system. Each choice can include a disjunction identifier and a choice identifier identifying one of the disjuncts of the identified disjunction. The logical combination of choices in a context identifier thus corresponds to a combination of disjuncts, all of which could be from different disjunctions. If two data units have context identifiers identifying contexts that are genuine alternatives, those data units are not unified. Data units that have context identifiers that are not genuine alternatives are unified. A set of context-value pairs, referred to as a disjunctive value, can be unified with another disjunctive value by considering all combinations of pairs of context identifiers that include one context identifier from each disjunctive value. The number of combinations of context identifiers in each disjunctive value is reduced by combining context-value pairs: Pairs with equal value tokens are combined by merging their context identifiers and unifying the value tokens. Pairs with f-structures as values are combined by merging context identifiers and unifying the f-structures. An equality within a disjunct is handled by unifying the equated entities, but only in the context appropriate to that disjunct. If it is necessary to insert a pointer, the pointer is inserted so that it initially leads to a disjunctive value, with the source of the pointer indicating which of the context-value pairs in the disjunctive value is to be accessed. This technique can avoid exponential growth for some classes of the NP-complete problem that occur in such domains as natural language processing.

Inventor: WILBER JAMES ALBERT
IPC: H04N3/18
Filed: 1989-11-09
Abstract: A horizontal deflection circuit (100) includes a flyback transformer (T1). A secondary winding (W2) of the flyback transformer (T1) is coupled in series with a diode switch (70) to produce a trace rectified supply voltage (V) that energizes a vertical deflection amplifier (40b). The diode switch (70) also provides switching operation in an East-west diode modulator (30). During, for example, service mode operation, when the vertical raster is collapsed, the current in the secondary winding (W2) during trace is substantially reduced. The reduced current during trace is sensed (by R15) for producing a control signal that causes the peak current supplied to the diode switch (70) by the diode modulator (30) to be smaller than the current in the secondary winding (W2). This ensures that the diode switch (70) remains conductive throughout horizontal trace, thereby preventing an undesirable increase in the supply voltage (V) from occuring.

Abstract: Known line-connector transmission networks exhibit repeater stations which are provided with distribution frames to be switched over manually. Recently, there has been a demand for creating electronically controlled distribution frames or network nodes for the operating stations of the transmission network so that a standby path can be very rapidly switched when a connection fails. …<??>The fundamental problem is to switch the digital signal connections even when no central network management is available either in the setting-up phase or due to a disturbance. In the transmission network according to the invention, the terminating network nodes (A, C) of the connection to be switched insert into the digital signal to be transmitted an identification which designates the source network node (A) and its input port 2 for the digital signal and the destination network node (C) and its output port (6). This identification is received in the following network node and forwarded to the next network node in each case up to the other terminating network node. …<??>All network nodes check the received identification, which enables them to carry out the stand by switching rapidly in the case of disturbances. …<IMAGE>…

Abstract: The invention proposes a hydraulic motor, the displacement of which can be adjusted in accordance with a new type of adjustment principle. The adjustment principle is based on the known hydraulic two-point adjustment from a maximum displacement to a minimum displacement. The minimum displacement is here subject to a control pressure-dependent limitation of the possible regulation pressure. The regulation pressure stipulated for the high-pressure regulating circuit is guided by an additional pressure regulating valve as a function of the control pressure, not as a function of the high pressure. If this variable displacement motor is combined with a commercially available variable displacement pump and the rotational speed-dependent control pressure produced in the automatic movement mechanism of the variable displacement pump is used to control the variable displacement motor, a hydrostatic transmission is obtained, the automatic movement mechanism of which not only permits automatic follow-up movement but, in addition, supplies the variable displacement motor with control signals for the optimum utilisation of the driving power available. …<IMAGE>…

Abstract: An electronic output transformer permits elimination of hum and other ground loop interference from audio signals transmitted between separated pieces of equipment. The transformer has a balanced differential output and feedback circuits which force the differential output voltage to equal the input voltage (Ein), and which force the current in the balanced output lines (14,16) to be precisely equal and out-of-phase. This permits hum and extraneous signal rejection at the input of the remotely located piece of equipment and results in common mode rejection ratios in excess of 100db.
