Abstract: ABSTRACT         In renovating bathrooms, it is known to form a unitary tub and shower enclosure out of a suitable plastic material, usually acrylic.  However because of the large size of these enclosures, it is necessary to cut them into, for example, three pieces so that they can be taken through the bathroom door.  Once in the bathroom, they are re-assembled, with joints between the pieces.  One type of joint utilizes an H-shaped sealing member of vinyl material which is softer than acrylic and not as attractive in appearance, particularly after some time when it deteriorates.          Also, the joint thus formed is not entirely satisfactory.  The present invention provides an improved joint between the pieces in which mateable surfaces extending backwards from the front surfaces are mechanically joined, preferably with silicone sealant between the surfaces.  The surfaces can slope so that any moisture tends to drip down into the tub.  Also, each joint can have an over-hanging lip so that water running down the wall of the enclosure will drip into the tub and not go into the joint.  The enclosure is made by thermoforming a sheet of thermoplastic material to include mateable surfaces between different sections, but with regions of waste material extending between the mateable surfaces.          This material is simply cut away so that the mateable surfaces can be joined together mechanically.

Abstract: ADJUSTABLE MAST STEP     Abstract of the Disclosure A mast step is mounted on a traveler having two parallel linear bearings which ride in lateral grooves on a central track.  The central track has downward enlarged vertical holes on 2-inch centers which hold detent balls.     The detent balls are locked in their upper active position with a contact and lock the traveler in a preselected position.  Depressing an operator pedal moves a slider bar within the track to align detent receivers with the openings in the track.  As the detent balls drop into the receivers in the slider bar, the platform is released to move toward a new location.  When the pedal is released, a spring tends to return the slider bar to misalign the receivers with the track openings.  The detent balls are ramped upward out of the receivers into their upper operative position in contact with the downward opening locking recesses in the traveler.

Abstract: CONTRACEPTIVE HOOD ABSTRACT OF THE DISCLOSURE A male contraceptive hood which is adhesively secured to the penis, the hood being initially rolled up with adhesive between the turns of the roll.  In a preferred  form,  the hood has  a  thin  sheath  which serves  as  the  contraceptive  device and  an  outer cylindrical member which is initially rolled together with the thin sheath.  The outer cylindrical member has an adhesive on a portion of its outer wall, which is transferred to the inner surface of the sheath as the hood is unrolled onto a penis.   Initially,  the adhesive  is  disposed on  the  outer surface  of  the outer  cylindrical  member  being  separated  from  the outer surface by a release agent.  When the sheath is rolled up, the adhesive on the outer surface of the cylindrical member comes into contact with the inner surface  of  adjacent  turns  of  the  sheath.   As  the sheath is unrolled onto the penis, the adhesive layer adheres to and is transferred to the inner surface of the sheath so as to cause the sheath to adhere to the head of the penis.  The outer member can then be removed leaving only the thin inner sheath on the penis.  A projecting portion is provided on the outer member for grasping the outer member to remove it.         The  contraceptive  hood  may  be  relatively short so as to extend only slightly beyond the head of the penis.  Even though the hood is relatively short it is retained in position by the adhesive.  Or the hood may extend over substantially the entire length of  the  penile  shaft.   Again,   the  adhesive  is effective in retaining the hood in place.

Abstract: ABSTRACT: "Mixer arrangement comprising first and second quadrature mixer stages".          Mixer arrangement (M) comprising first and se-cond quadrature mixer stages (M, resp. M2) to which qua-drature mixing signals are applied from an oscillator circuit (F0), these two mixer stages (M1 and M2) being coupled to a superposition circuit (S0). To suppress inter-ferences occurring in the output signal of the superposit-ion circuit due to oscillator crosstalk or leakage and/ or a d.c. offset of the mixer stages (M1 and M2) which are supplied with mixing signals by the oscillator circuit F0, the quadrature components of these interferences being in phase with the quadrature mixing signals are measured by means of first and second synchronous detectors (SD1 resp. SD2) to which detection carriers are applied in an in-phase or an anti-phase relationship with respect to the quadrature mixing signals.After sign inversion these qua-drature components are fed back to the inputs of the two mixer stages(M1 and M2), resulting in an interference ne-gative feedback.

Abstract: TITLE OF THE INVENTION               FLEXIBLE HEATING CABLE             ABSTRACT OF THE DISCLOSURE    A flexible heating cable includes a first conductive body, a second conductive body, a thermally fusible electrically insulative body which are arranged such that the first and second conductive bodies will be brought into electric contact with each other when the thermally fusible electrically insulative body is thermally fused, a third conductive body, and a heating body having a positive temperature coefficient and held in electric contact with at least one of the first and second conductive bodies and the third conductive body.  The flexible heating cable is capable of self-controlling the temperature of the heated heating body.  The flexible heating cable can detect the danger of localized overheating, abnormal overheating, or the generation of an arc which is caused when the heating cable is subjected to external oppression, bending, or twisting, or when the heating cable is heated by an external source, or when a conductive material has been mixed in the PTC heating body.  Through such detection, the flexible heating cable is prevented from being overheated beyond a certain temperature setting.  The flexible heating cable will not be heated up to a high temperature after use over a prolonged period of time.  Therefore, the flexible heating cable has a sufficient degree of safety.

Abstract: ABSTRACT OF THE DISCLOSURE          This specification relates to a construction of a magnetic tape cassette.  The specification discloses a magnetic tape cassette whose A and B sides are easily dis-tinguishable from each other and which also permits ready identification of either the feed or takeup hub in the cassette housing from the outside.  The magnetic tape cas-sette disclosed herein is characterized in that transparent upper and lower housing halves are mated together at surround-ing walls so that the interior is visible from the outside, and each said half is lined with a transparent lubricant sheet and is provided with a mark of letter A or B in color assigned to, and indicative of, the A or B side and also provided with a strip of label extending centrally and longi-tudinally of the cassette on a part where the both hubs wound with the tape are visible from the outside, the feed hub visible through each housing half being colored in the same color as the letter and label on the particular half.          The construction that characterizes the present invention permits immediate identification of the A or B side by a glance at the letter A or B and the label indicating either side, even in dimly lit places.  The two sides can also be easily distinguished from each other while the cassette is set in the recorder.  Since the hub visible on a given side and having the same color as the label on the particular housing half  is always the feed hub, the user can simply realize which side, A or B, should now come to the front for recording or playback.

These opposite faces are subjected to a fluid pressure difference which produces deformation of the portions towards a conformation substantially identical with the conformation of the valve flaps when mounted in the prosthesis.  The biological tissue is finally fixed whilst the portions defining the valve flaps of the prosthesis are maintained in the said conformation. The sheets of biological tissue are then separated from the forming means to be subsequently mounted in the frame of the prosthesis.
