Abstract: ABSTRACT:              In accordance with a method of recording and/or reproducing stereophonic information in two adjacent tracks of a magnetic record carrier an auxiliary signal whose frequency content is situated beyond the frequency spectrum of the stereophonic information is recorded in the tracks and in the magnetic record-carrier area between the tracks during recording.  During reproduction use can be made of the auxiliary signals read from the record carrier by the two transducers in order to obtain a control system which ensures that the amplitude of the stereophonic information thus reproduced becomes independent of tracking errors.

Abstract: ABSTRACT OF THE DISCLOSURE          The seal consists of a hollow stud member which is welded to the enclosure to be secured and a cap member which holds the enclose cover in place when secured to the stud.  The cap member has a body sec-tion and a pin element extending from it.  The pin element has an end portion that is shaped an as to be permanently secured once it enters a receiving element in the stud member.  The cap member further has a ran-dom identity element, such as a randomly wound coil mounted in a cavity within the cap body.  One end of the identity element is fixed to the cap member body section and the other end is fixed to the pin element end portion; such that the identity of the identity element is altered when the end portion is broken away from the pin element.

Abstract: ACID SOLUBLE BLUE COLORANT FOR FOOD PRODUCTS ABSTRACT Spirulina blue, which is not soluble at low pH, is subjected to enzymatic hydrolysis in an aqueous alkaline medium. The pH of the aqueous system is lowered and the liquid phase is dried to produce a blue dye in dry form which is soluble at low pH. The blue dye is useful as a blue colorant in food products, particularly food products, such as bev-erages, in which acid solubility is desired.

Abstract: ABSTRACT OF THE DISCLOSURE            There is disclosed herein a flow-through medical filter element which includes surface or depth filter media and a frame-like structure for supporting and positioning the media.  The frame-like structure is a molded member which includes a ring-like inlet, a fluid-impervious terminal end spaced from the inlet and a plurality of rib-like members which extends be-tween and interconnect the inlet end and terminal end. The inlet end includes internally-extending pleat-supporting projections and the terminal end has comple-mentary externally-extending pleat-supporting shoulders. The frame-like structure is symmetrical about an axial plane which includes the mold parting line.  The ex-ternal shoulders are formed at angles which permits separation of a mold along the parting line and release of the part.  The filter media also includes longitu-dinal pleats and is secured at its end to the pleat-supporting projections associated with the inlet end and to the external pleat-supporting shoulders at the terminal end.  Thus blood enters the filter element flows through the media and thereafter exits the filter ele-ment.    This construction permits for a molding operation and provides a high surface area filter for use in existing units.

Abstract: Abstract The invention relates to an arrangement in cylinder drying, intended for incorporation in a paper machine and including a plurality of heated cylinders (l) arranged substantially parallel in two rows, about which the paper web (2) is taken serpentine during drying, whereat it is carried by an endless porous fourdrinier wire (3) which presses the web against the cylinder surfaces in one row of cylinders and lies between the paper web and the cylinders in the other row. For preventing the web from lifting from the wire as a result of pressure differences on either side thereof, there are blowing boxes (11,12) arranged for blowing out air in at least some of the pockets (4,5) situated on opposite sides of the web, each of said pockets being formed by the web and three cylinders lying consecutively in the travelling direction of the web. Blowing out from the blowing boxes takes place in directions such that a sub-pressure is generated in the pockets (4) where the wire (3) lies outmost towards the pocket, and an excess pressure generated in the pockets (5) where the paper web (2) lies outmost towards the pocket.

Abstract: ABSTRACT         TELEVISION SIGNAL TRANSMISSION A television picture transmission system using conditional replenishment employs a scanning rate at the transmitter which differs (for asynchronous operation, slightly; or for operation between systems using different standards, considerably) from the scanning standard at the the receivers  The frame rate conversion is effected by the updating loops at the transmitter or receiver by, respectively, periodically stopping the coding loop for a field or frame so that no data is produced to produce a lower frame rate or periodically repeating a field or frame in the loop without adding any updating data so as to produce a higher frame rate.  Resulting variations in data rate are accommodated by utilising the buffering inherent in conditional replenishment systems. The jerkiness of motion in the received picture resulting from stopping the loop or repeating a field or frame can be reduced by the use of temporal interpolation in the generation of the updating data to anticipate the stopping or repeating of a field or frame, whilst conversion of the number of lines per frame can be effected by spatial interpolation using a transversal filter.

Abstract: ABSTRACT      A fluid sealing gasket device for a spin-on, throw-away filter having an annular sealing gasket with a groove of a particular shape in cross-section, the groove being formed circumferentially at the outer peripheral wall thereof; a substantially correspondingly shaped annular, metal reinforcing member positioned in and extending from the correspondingly shaped groove; and an annular gasket retaining channel formed in the filter end plate for retaining the reinforced sealing gasket therein. The gasket has a lower portion positioned in the retainer channel and an upper portion extending therefrom, with the annular groove and reinforcing member located in the upper portion of the gasket. Alternatively, the reinforcing member effectively fills "void" when the gasket is molded therearound.  This fluid sealing gasket device retains the gasket's structural integrity upon installation on the filter mount l during use when High fluid pressures are exerted on the gasket from the inside of the filter. Thus this reinforced fluid sealing gasket device minimize deformation, improper orientation, and improper displacement of the gasket during installation and use of the filter, thereby assuring that the gasket is fully effective for sealing the filter to the filter  mount and preventing leakage of the fluid.

Abstract: ABSTRACT OF THE DISCLOSURE     From a pile or stack of cups, which is available in a magazine, the lowermost one is released with the aid of a slide in such a way, that simultaneously a retaining device is slid away from and a separating and releasing device is slid in between the rims of a lowermost cup and the one above it.   In such a way, a positive release of a cup is possible.   The separating and releasing device is  provided with upper and lower inclined  surfaces  and their common points are bevelled away from each other in the direction of feeding or releasing.   Due to a bifur-cated shape of the slide   and  provision   of   same with the separating and releasing device as well as the retaining device on the inside of the slide shanks  or  bifurcations one  immediately behind  the  other  in  sliding  direction, great  dependability  is  attained  and  the  separating  and releasing device can be manufactured   at   comparatively low  cost,  particularly because  all  essential  parts  are made in one piece together with the slide.   There is no need for provision of a device for retaining a cup pile or for separating and releasing cups at the cup magazine itself.

Abstract: ABSTRACT          Start-Up Control Method and Apparatus for a Polyphase Induction Motor In order to minimise the initial in-rush current produced on first energisation of a polyphase induction motor (10), careful control is exercised over the firing of controlled switching means (11) connected in series with each of the supply phases (A, B, C) or motor windings. This control includes effecting an initial selective firing of the switching means (11) such as to cause current to flow between two only (B, C) of the supply phases, the firing being timed to occur such that the voltage between these two phases (B, C) is decreasing in value at the moment of firing.  Thereafter, the switching means (11) are sequentially fired in a manner resulting in the progressive increase in the angle of conduction of each switching means (11).            (Fig. 1)
