Abstract: ABSTRACT          Containers made of flexible material often have opening arrangements in the form of a tear strip for opening an outlet aperture. The tear strip constitutes a part of the container wall and is limited by a weakening line. To facilitate initiation of the tear-open operation a short length of the weakened line has the form of a cut or cuts extending fully through the material. Two or more cuts may form a lug or projection, and if located at a fold line of the container blank the lug or projection may be arranged to automatically extend outwards from the finished container.

Abstract: Abstract of the Disclosure A liquid component can be introduced into a detergent bar by injecting liquid within or immediately downstream of a multi-apertured plate positioned before the compression cone of an extruder.  The method can be used to produce marbled bars with the aid of a coloured liquid and is des-cribed in UK 1387567.    When a double extruder is used together with a common compression cone the injected liquid becomes unevenly dis-tributed within the detergent.  Even distribution of the liquid as striations is achieved by use of a partition in the cone to ensure each detergent stream is subjected to separate compression during movement down the cone.   The partition extends to the final extrusion plate; the velo-cities of the two streams are equalised by having a common extrusion volume between the two screw extruders and the multi-apertured plate.

Abstract: (Case No. 6997) ABSTRACT OF THE DISCLOSURE      A light emitting diode (LED) is coupled direct to the local source of alternating current track circuit energy through a transformer, with a band pass filter tuned to track circuit frequency included in the transformer secondary connections to the LED.  The LED responds to each positive half cycle of the local signal and is focused to illuminate a photo resistive cell (PRC) to actuate similar periodic reductions in its resistance.  The PRC is coupled to the electrified track section rails through a saturable transformer to receive track circuit energy from the same source through the section rails.          The LED and PRC function as a synchronous rectifier, when the local and track signals are of the same frequency and rela-tively in phase, to provide an averaged direct current signal component from the saturable transformer secondary to a biased direct current track relay, which picks up to indicate an unoccupied section and releases when the section is occupied or a broken rail occurs.  The circuit arrangement rejects signals of propulsion power frequency and its harmonics and sharply attenuates the D. C. output if the inputs are out of phase beyond predetermined limits.

Abstract: ABSTRACT      Control apparatus and methods wherein distance pulses calibrate the movement of load-carrying members past receiving stations.  Location codes for the members indicative of the station at which each respective member is to discharge its load are entered into a shift register having a plurality of stages equal in number to the greater of the number of load-carrying members and discharge stations plus one.  The location codes move through the register responsive to each preselected number of distance pulses generated, with arrival of a member at the station where its load is to be discharged indicated by the arrival of the location code for that station at a stage of the register corresponding to that station.  Fine tuning is achieved by requiring generation of a preselected but adjustable number of distance pulses after indication of arrival at a station of a member to be discharged before that member is in fact discharged.          Adjustment of the preselected number of distance pulses required before discharge fine tunes the precise location of discharge.

A needle is slidably positioned in the lumen so that its point protrudes slightly beyond the distal end of the tube, whereas the other end of the needle extends through the hub and sealingly contacts the same so that the hub is effectively closed.  A blocking device is contained in the cavity which is adapted to block the entrance of the lumen after the needle is withdrawn from the catheter tube to prevent ready re-insertion of an instrument into the lumen; however, flow of fluids into the lumen is not blocked.  The hub includes an access provision to the cavity whereby fluids may be deposited into the cavity for delivery to a patient after the needle has been withdrawn from the catheter tube.

Abstract: ABSTRACT OF THE DISCLOSURE Some free water containing glass batch agglomerate formulations when attempted to be dried and heated in a vertical bed (3) prior to being discharged to a glass melter (1) for vitrification convert into large aggregates which cannot be suitably supplied to the melter.  The present invention solves this process disabling aggregate formation by treating such agglomerates in a preconditioning chamber(s) (11, 21, 31, 41) prior to supplying them into a vertical bed (3) so as to preclude serious aggregate formation in either the preconditoner or the vertical bed.  Such treatment is employed in manufacturing glass with a fossil fuel fired melter or an electrically operated melter.

Abstract: ABSTRACT Disclosed is a process for the transmission of data with a mod-ulated carrier via a two-wire line from a first station to a remote station and vice versa.  The modulated carrier is split into two orthogonal signal components and as a result of correlation with a difference signal supplied to the receiver, a first and second regulating signal is produced.  The first and second regulating signal each regulate a base band simulation stage, whose output signals - taking into account the two orthogonal signal com-ponents - form the components of a compensation signal which is used to sup-press a cross-talk signal.
