Abstract: ABSTRACT OF THE DISCLOSURE           Axial compliance/sealing means are provided for scroll-type apparatus.  These means comprise seal elements capable of experiencing axial and radial motion within chan-nels cut in the tips of the involute wraps to make sealing contact with the end plates of the opposing scroll members.          Continuous involute spring members having a pitch larger than the wrap involute channel provide a mechanical force applying means to urge the seal elements into sealing contact.  The use of the axial compliance/ sealing means allows the contacting surfaces  through which  radial sealing  is effected to be machined to conventional accuracy,  and provides automatic compensation for temperature differentials within the appar-atus as well for any uneven wear of the scroll members.  The sealing means is particularly suited for reliable extended operation in a hermetically sealed apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus and a method for removing suspended particles from water in a circular tank having a distribution and flocculation chamber immersed in the tank of water and carried circularly around the tank by a carriage. Flocculating material and inlet water are introduced into the body of water from the moving flocculating chamber at the same rate as clarified water is discharged through a filter substantially covering the bottom of the tank. A majority of particles in the water is collected by flocs in the water and floated to the water surface by air bubble action. The floating sludge is removed by a spiral scoop carried by the carriage. The water is then passed through the bottom filter which removes the remaining flocs completing the clarification of the water for discharge.          Apparatus is provided for electively back washing sections of the filter while the remainder of the filter is in operation.

Abstract: Abstract of the Disclosure A clean release label or the like is produced by lamination of a plurality of sheets, including a face sheet and a backer sheet,  the laminating process is performed by use of a selected fugitive adhesive which attaches the sheets together.  Then one or more of the laminated sheets is die cut and a portion thereof is removed as a matrix. A remaining portion of the sheet constitutes a removable label or the like which is carried by the backer sheet.  The label is removable from the backer sheet as cohesive failure occurs in the fugitive adhesive.  Therefore, the label and the portion of the backer sheet from which the label is removed are non-tacky and non-waxy.           A three ply embodiment of this invention comprises a clean release product comprising a face sheet attached to a backer sheet by fugitive adhesive.  The backer sheet is attached to a silicone release surface of a carrier sheet by a pressure sensitive adhesive applied to the back of the backer sheet.  Labels are formed as the face sheet and backer sheet are die cut followed by removal of the matrix.  The face sheet and backer sheet as a unit are either manually or mechanically separated from the carrier sheet and attached by the pressure sensitive adhesive to a business form or other suitable surface.  The face sheet may be printed upon before or after attachment of the two ply unit to the business form.  Then the face sheet is separated from the backer sheet. The face sheet thus serves as a label, identification card, or the like, having a clean back surface and leaving a clean exposed surface of the backer sheet, which remains attached to the business form by the pressure sensitive adhesive.

Abstract: ABSTRACT OF THE DISCLOSURE    A fault point in a line section of a three-phase power transmission line, is determined by measuring currents and voltages at a measuring point arranged adjac-ent the near end of the section.  The type of fault (single-phase/multi-phase ground fault/phase-to-phase fault) is determined and the parameters in a quadratic equation are determined using the relative distance (n) from the measuring point to the fault point as a variable. The equation is derived in advance from the electrical relationships between the complex values of the line impedance, the source impedances of the networks located ahead of and behind the fault, and measured currents and voltages following elimination of the fault resistance and possible zero sequence components.  The parameters in the equation are determined by the type of the fault, by the measured voltages and currents and by said imped-ances.  The equation is solved directly by means of a numerical square root method.  When calculating the para-meters, the fundamental frequency components of the measured values are used,which components are obtained by digital filtering of the measured values. The invention also relates to a device for carrying out the method.

Abstract: ABSTRACT OF THE DISCLOSURE     A braking control circuit for alternating current motor is described.  As is conventional an SCR is operative when the AC voltage is disconnected from the motor winding to supply DC braking pulses to the motor winding.  According to the invention, however, the braking time is divided into a first period during which the braking torque is high and a subsequent period of lower braking torque.  This is achieved by applying large conductive angle pulses via the SCR during the first period and lower conduction angle pulses during the second period.
