Abstract: APPARATUS FOR SUPPLYING AIR-FUEL MIXTURE      IN INTERNAL COMBUSTION ENGINE                ABSTRACT OF THE DISCLOSURE An apparatus for supplying an air-fuel mixture through a collecting passage of an intake manifold to a cylinder of an internal combustion engine.  The flow of the air-fuel mixture from the intake passageway of a throttle body is discharged transversely into the collecting passageway so that the mixture strikes a region on a side surface of the collecting passageway.  Also provided is an arrangement for supplying an auxiliary air stream into the collecting passageway from a location across the striking region from the engine cylinder, which arrangement directs the auxiliary air toward the center of the striking region.

Granted: 1993-01-05
Abstract: ABSTRACT The signal-to-noise ratio of a transimpedance operational amplifier is enhanced by employing a large feedback resistor. Bandwidth lost in the process recaptured by a compensation network without reducing the signal-to-noise ratio. The compensation network provides a zero which cancels the upper 3 db pole of the transimpedance amplifier, and also provides a high frequency pole defining the restored bandwidth of amplifier.

Granted: 1993-08-17
Abstract: NOISE ISOLATING MOTOR MOUNTING SYSTEM FOR A CANISTER VACUUM CLEANER                           Abstract An arrangement for mounting a motor blower assembly in a canister vacuum cleaner uses a pair of resilient rubber rings, one each on the front and rear of the assembly, to isolate the motor from the vacuum cleaner housing.  The front ring goes over the front of the fan casing and is trapped within the housing, while the rear of the motor has attached thereto an adaptor which fits within the complementarily shaped rear rubber ring.   This rear rubber ring in turn fits within a complementarily shaped motor support, which is attached to a support abutment within the housing.  In order to accommodate different size motors within the same housing and utilize the same mounting components, the support abutment is pre-drilled at various locations to accommodate the different size motors.  Thus, the only fixed attachment to the housing is the rear support, which is isolated from the motor blower assembly by the rear rubber ring.

Abstract: A method for removing double metal cyanide complex catalyst from polyether polyols is disclosed which uses alkali metal compounds and phosphorous compounds to precipitate the residual catalyst, which may then be removed by filtration.  In one embodiment, a propylene oxide polyol is treated with sodium metal dispersion, capped with ethylene oxide, treated with magnesium silicate, and then filtered to remove at least a portion of the catalyst.  Substantially complete catalyst removal is then achieved by treating the polyol with hypophosphorous or phosphorous acid to precipitate the remaining solubilized double metal cyanide complex catalyst residue, neutralizing the excess acid with magnesium silicate, and filtering.

Abstract: METHODS FOR HIGH Tc SUPERCONDUCTOR FILM DEPOSITION     ABSTRACT OF THE DISCLOSURE      The present invention describes two simple methods to prepare high Tc multi element superconductor films. In the first method, metallic elements (or oxides) are deposited sequentially on substrates in a vacuum system.  The film composition is controlled by controlling the amounts of the source materials introduced into the boats.  In addition, one or more of the elements (or oxides) are-introduced to the films by treating the films in an environment containing such elements. The other method described involves the deposition of films on substrates with arbitrary shape using a non vacuum paint on method.

Abstract: The anodes for the electrolytic production of zinc from acid aqueous solutions of sulphate comprise a skin portion formed by conventional anode metal, lead containing from 0.25 to 1.0% silver, and a stiffening reinforcing member of titanium or zirconium. The reduction in thickness of the anodes, which is made possible by the provision of the reinforcing member, results in a substantial saving in the amount of silver-bearing lead which is immobilized, and a substantial reduction in the unit weight of the anodes. The resistance of the lead to anodic corrosion in a sulphuric acid medium is maintained and the resistance to corrosion by passivation of the reinforcing member permits the reinforcing member to be accidentally exposed, without disadvantage. To produce the anodes, the reinforcing members are clad with lead at a temperature of more than 100 DEG  by rolling sheets of lead, by casting in a mould or by spraying on molten lead.

Abstract: For introducing gases, wires and powders to metal melts, a multi-ducted refractory body (11) is installed in the wall (14) of a vessel (15) for the melt. The body has passage closing elements (24, 34, 35) preventing melt entering the passages (A, B, C). Two passages (A and C) serve respectively for introducing gas, and fluidised powders, to the melt; each has a movable pipe (36, 91) (for gas or fluidised powder). Upon moving gas pipe (36) towards the melt, it dislodges closing element (24) whereby gas from the pipe can enter the melt via capillary bores (25). Similarly, by moving pipe (91), closing element (35) is dislodged whereby the fluidised powder can discharge from the pipe (91). Wire is fed along passage (B) to the melt: when it reaches the closing element (34) the wire can itself dislodge this element to gain access to the melt.A method of introducing substances to liquids related to use of this apparatus is disclosed, as well as metallurgical processes involving the method.
