Abstract: ABSTRACT "TV-IF circuit".     TV-IF circuit comprising a balanced video signal path (A5, M, A6, VM) arranged between an IF-input (1, 1') and a video signal output (2, 2') and a balanced sound sig-nal path (A1, A2, A7, SM) arranged between the IF-input (1, 1') and a sound signal output (3, 3'), these two paths comprising a video mixing stage (VM) and a sound mixing stage (SM), respectively for a quasi-parallel sound signal processing or an intercarrier sound signal processing. The compatability between these two modes of sound signal pro-cessing increases  the range of applications compared with prior art TV-IF circuits and this is accomplished by a ma-trix circuit (M) comprising a balanced, non-inverting (5,5') and a balanced, inverting (4, 4' ) input, as well as a ba-lanced output (6, 6'), the matrix circuit (M) being included via the non-inverting input (5, 5') and the output (6, 6') in one (A5, M, A6, VM) of said two signal paths (A5, M, A6, VM or A1, A2, A7, SM) between the IF-input (1, 1') and a signal input (7, 7') of the mixing stage (VM) in this sig-nal path (A5, M, A6, VM), the other signal path (A1, A2, A7 SM) between the IF-input (1, 1') and a signal input (10, 10') of the mixing stage (SM) in the last-mentioned signal path A1, A2, A7, SM) being connected to the balanced, inverting input (4, 4') of the matrix circuit (M) and comprising be-tween the IF-input (1, 1') and the matrix circuit (M) a balanced first pair of terminals (9, 9') which may optional-ly be shortcircuited, remain open-circuited of for connect-ing therebetween a resonant circuit (FSC) having a resonant frequency which corresponds to a sound carrier frequency of the TV-IF signal applied to the IF-input.

Abstract: ABSTRACT OF THE DISCLOSURE      Force measuring equipment has a magnetoelastic trans-ducer with an excitation winding supplied with alternating current, which generates a primary flux in a magnetic core of the transducer, and a measuring winding in which a signal voltage is induced, the signal voltage giving a measure of the force applied to the transducer core.          The signal voltage is supplied to signal processing members which are arranged to form an output signal by phase-sensitive rectification of the signal voltage.  Control members sense when the primary flux passes a positive and a negative reference level, and switch polarity rever-sing members at the times during each period of the AC supply when the primary flux with a certain sign of its time rate of change passes the positive reference level and with the opposite sign of its time rate of change passes the negative reference level.

Abstract: TWELVE PULSE LOAD COMMUTATED INVERTER DRIVE SYSTEM Abstract of the Disclosure A control system for powering an AC load such as a polyphase synchronous motor having at least two sets of three phase (3) windings.  Each three phase winding set is powered by an independently operable six pulse load commutated inverter drive including a source side converter and a load side converter coupled together by means of a DC link and wherein the source side converter and the load side converter are operated in accordance with respective current and load angle regulators which respond to torque command signals generated by speed regulators.  The two motor drives operate concurrently in separate control channels which are substantially independent of one another with the exception that in one embodiment, which is the preferred embodiment, the speed regulator and the motor terminal overvoltage regulator are cross-coupled to effect a balanced torque command and motor terminal voltage from each channel while still providing for continued motor operation by one of the motor drive channels in the event that the other becomes inoperative for any reason.  In a second embodiment, one of two redundant speed regula-tors is adapted to provide a common torque command to both channels with the other speed regulator taking over in the event of the failure of said one speed regulator.

Abstract: LOW-FRICTION THIN-HUB PLASTIC MULTI-PART SHEAVE                     Abstract A low-friction thin-hub plastic multi-part sheave for handling wire, having two joined disc-like members with conical rim portions which together form a V-groove for the wire. The members have apertured central hub portions provided with facing shoulders that engage co-operable, oppositely-facing shoulders on the outer race member of an anti-friction bearing assemblage, to hold the latter captive between the disc-like members. The central hub portions and anti-friction bearing assemblage have respective, oppositely facing, parallel exposed side surfaces which are flush and disposed in spaced-apart parallel planes, making for a thin hub assemblage. the cooperable, oppositely-facing shoulders are prefer-ably conical. The disc-like members have large, shallow circular recesses in their exposed sides. The advantage of the present construction over the devices of the pri-or art is that by cutting off a rim portion of one disc-like member, it can nest in the recess of an adjoining, similar but un-cut disc-like member so that a plurality of sheaves with cut rim portions can be mounted in tan-dem on a common shaft, thus requiring considerably less space.

Abstract: ABSTRACT         In a parapet portion of a curtain wall, indoor side and outdoor side members of each panel unit mounted at the top of the curtain wall are connected via a connector made of heat-insulating material, and a damp-proofing sheet is mounted so as to extend between the indoor side member and a building body to form a heat-insulating damp-proofing layer, whereby the disadvantages that heat received by a coping from the external atmosphere would be transmitted to the indoor side of the curtain wall, resulting in deterioration of the heat-insulating property of the curtain wall, and that damp enclosed between the curtain wall and the building body would dew the inner surface of the coping, can be improved.  Preferably, the coping form-ing a principal member of the above-mentioned parapet por-tion should have a two-part construction consisting of an outdoor side part and an indoor side part, and these indoor side and outdoor side coping parts are connected so as to be slidable with respect to each other in the indoor-outdoor direction as well as in a horizontal direction at right angles to the former direction, whereby thermal expansion of the coping caused by heat received from the external atmosphere can be absorbed by the connecting portion, and moreover even if there exist some dimensional errors of the coping, mounting of the coping becomes easy.
