Abstract: ABSTRACT OF THE DISCLOSURE       A presser foot has a generally rectangular,solid block-shaped foot means made from transparent material and integral with a stem for securing the foot means to a presser bar of a sewing machine.  An aperture is provided in the foot means for needle passage.  The height of the foot means is such that the needle eye reaches out of the passage when in upper position, while the needle tip is generally coincident with the top surface of the foot means.  Thus, the invention provides a relatively inexpensive presser foot whose shape is also operative as a safety guard.

Abstract: ABSTRACT           This invention relates to a water soluble quaternized epihalohydrin copolymer.  The copolymer is prepared by first reacting an epihalohydrin with a polyepoxide in an organic solvent in the presence of a polymerization catalyst.  The copolymer thus produced is then quaternized by reacting it with tertiary amine.  The quaternized epihalohydrin co-polymer is useful in removing suspended solids from aqueous dispersions.  It is particularly useful in processes for clarifying raw water.

Abstract: ABSTRACT         A pollution-free process for the recovery of high purity zinc from zinc containing materiel including sulfide ores which provides for maximum conservation and re-use of reagents, the process consisting of chlorinating the materials either with ferric chloride or chlorine gas followed by selective removal of metals other than zinc by standard procedures, such as, lead chloride crystallization, cementation etc. to produce a solution containing essentially only zinc chloride and ferrous chloride.  To enhance the purity of the zinc end product zinc chloride is separated from the ferrous chloride solution with a zinc selective extraction agent from which the zinc chloride is stripped, with sodium chloride solution in a sodium chloride stripping circuit followed by precipitation of zinc as the carbonate. The sodium chloride formed in precipitating zinc carbonate with sodium carbonate goes to an electrolytic cell to produce chlorine and sodium hydroxide by electrolysis which latter is carbonated to sodium carbonate for circulation to the zinc carbonate precipitation.  The sodium chloride stripping circuit includes the electrolytic cell where excess chlorine is removed from the stripping solution.  The ferrous chloride raffinate from the zinc chloride extraction step is sent to a chlorination and hydrolysis step where ferric chloride leaching agent is regenerated and iron removed.  Chlorine from the electrolysis step is used for the chlorination step.  The process results in very little loss of reagents from the system.

Abstract: FUEL CONTROL VALVE                          ABSTRACT           The disclosure illustrates an anti-tampering fuel control valve for a fuel system providing fuel at a regulated pressure to a series of unit injectors on a diesel engine.          The injectors are cam actuated to inject fuel quantities related to the pressure of the fuel supplied to them.  The control valve bypasses fuel from the output of the fuel system to a low pressure region when the pressure exceeds a first given level because of fuel system tampering.  Orifices in the bypass flow path cause the fuel pressure to follow a schedule generally similar to the normal system pressure schedule but at lower levels.  Bypass flow is continued until the fuel system pressure drops to a lower pressure than the pressure at which bypass flow begins.

Abstract: ABRIDGEMENT      Method and apparatus for trimming cylindrical articles, particularly can bodies, to a predetermined longitudinal length by sequentially feeding such cylindrical articles into carriage pockets rotating around a main shaft synchronously with an axially aligned plunger at one end of each carriage pocket and a similarily aligned mandrel at the other end of the carriage pocket.  At predetermined positions, the plunger moves into the aligned carriage pocket and pushes a cylindrical article therein onto an aligned mandrel which is rotated around its own axis as well as around the main shaft.  As the mandrel rotates, a fixed arcuate blade which cooperates with a cutting edge defined in the mandrel is engaged to shear an annulus portion from the end of the cylindrical article thereby trimming the cylindrical article to a predetermined and repeatable length.  Upon severing of the annulus, a fixed cutter blade engages the annulus to transversely cut the annulus into an open ring.  Thereafter, the open ring is rolled, straightened and deposited as a strip in a chamber defined adjacent each mandrel with the severed strip being carried to a waste disposal position as the mandrel rotates around the main shaft.  The trimmed cylindrical body is removed from the mandrel for further processing and the plunger retracted from the carriage to permit insertion of yet another untrimmed cylindrical article into the carriage device.

Abstract: A SELF-ADJUSTING SEAL ASSEMBLY                        ABSTRACT OF THE DISCLOSURE     A self-adjusting seal assembly is formed to fit around a member extending from a structure which is thermally insulated with insulation panels but which leaves a gap around the in-sulated member.  The self-adjusting seal assembly covers this gap and automatically compensates for any gap variation due to thermal expansion and contraction.  The assembly has a first spring biased seal member located on the insulation panel to partially abut against the member and partially seal the gap around the member.  A second seal member is spring biased to abut against the first seal member to thereby completely en-close the member and the gap around the member.  As the struc-ture member expands or contracts the spring loaded seal mem-bers move to retain their position abutting the member and maintain the integrity of the gap seal.

Abstract: 46,106 FAST DE-EXCITATION BRUSHLESS EXCITER            ABSTRACT OF THE DISCLOSURE         Thyristors are substituted for conventional diodes in the rotating rectifier assembly of a brushless exciter in a synchronous dynamoelectric machine.  In contrast with prior systems in which thyristors are switched at relatively high ceiling voltages (requiring thyristors of high power rating and additional components for fast de-excitation), the gates of the thyristors in the present invention are fired only at a low voltage point of the negative half cycle of the polyphase armature voltage waveforms for fast de-excitation and are maintained in a fully conducting condition during the positive half cycle. This permits the use of thyristors having a relatively lower power rating and makes unnecessary additional components to achieve fast de-excitation.
