Abstract: ABSTRACT            A plastic gutter is designed with a longitudinally extending bead  (5)  under an outwardly facing lip (4)  and  a  corresponding  longitudinally  extending bead (5) on the inside of the rear part. At least at   the  end  of   each  length  of  gutter  the longitudinally extending beads have been machined in such a manner that material has been removed at regular intervals so that the remaining material constitutes one or more locking pieces (6).          An assembly piece  (7)  with a rubber packing  (8) for  assembling  adjoining  lengths  of  gutter,  for example,  has  a  number  of locking  holes  (9)  in an  outwardly  facing  lip  (11)  and  a  number  of corresponding  locking  holes  (9)  in  a  bent  edge part (10) at the rear.       There  is hereby obtained a gutter which is both quickly  and  easily  mounted  and  taken  down  and where  the  parts  are  nevertheless  securely  held together  so  that  an  axial  movement  between  the parts will not occur.

Abstract: MINIATURIZED TAPE CARTRIDGE DRIVE       FOR DATA PROCESSORS ABSTRACT OF THE DISCLOSURE A miniaturized cartridge-type tape drive for data storage applications having a main support frame upon which are mounted a tape-drive motor and a transducer-positioning motor, disposed one behind the other in generally tandom position.  Both such motors preferably have generally flat silhouettes, enabling the drive to be small and compact, and both motors are directly-coupled to corresponding actuating members, i.e., a tape-driving capstan for the tape-drive motor and a rotary positioning cam for the transducer-positioning motor.  An elongated transducer-positioning linkage arm extends from the rotary cam, which is nearer the rear portion of the support frame, to the transducer, which is nearer the front portion of the frame, and the arm has pivot-mounting structure toward the center portion of its length mounted in corresponding pivot mounts on the main support frame.

Abstract: PHN. 10.981 ABSTRACT:           The invention relates to a DC/AC converter (8), having a half bridge circuit and which serves for igniting and feeding a gas and/or vapour discharge tube (1). According to the invention, a starting capacitor (94) of this converter is connected between a junction (A) between two branches - each comprising a semi-conductor circuit element (60 - 61, respectively) - of the half bridge circuit on the one hand and a centre tapping (E) of a voltage divider (90, 91) on the other hand.  As a result, the converter (8) starts satisfactorily and hence the discharge tube (1) readily ignites, while moreover undesired starting pulses during the operation condition are avoided.

Abstract: ABSTRACT A diversity system of the selection type is disclosed.  It includes N (?- 2) receivers for receiving multi-phase PSK or multi-level QAM waves carrying differentially modulo-M (equal to or more than 2) encoded digital signals and providing N sequences of demodulated digital signals by phase-detecting the waves with a recovered carrier wave. Selector circuitry is pro-vided for selecting out of the N sequences of demodulated digital signals one with a low bit error rate.  The selected one of the sequence of demodulated digital signals is aligned with other sequences of demodulated digital signals, thereby providing a demodulated digital signal sequence retaining the differ-ential encoding as the output of the selector circuitry.  In the system of the invention differential decoders in the relay station are dispensed with.

Abstract: ABSTRACT OF THE DISCLOSURE            Pistons  and cylinders are manufactured to an oval  shape, which  is defined as being an oval where the ratio of  the major  axis  to the minor axis is between 1.1:1 and  3:1. Pistons  and  cylinders are generally finish  machined  by relative  rotation between the tool and the workpiece  and movement  of  the  tool  in a defined path  to  produce  a finished  profile.    In  general,  however,  conventional machine  tools  cannot  machine  such  oval  profiles   at commercial  production  rates because of  the  excessively high  tool  accelerations which this would involve and  of which  the  conventional machine tools  are  not  capable. Disclosed  are  a  machine tool for  machining  such  oval pistons in which an oval piston blank is rotated in a path such  that,  when each part of the piston surface  reaches the  tool,  it is at a constant datum position.   Thus the tool considers that it is machining a surface of  constant radius and normal tool movements can be performed.   There is also a boring machine for machining such oval cylinders where  the  tool  is moved in a  required  oval  path.   A mechanism  is  disclosed  which  can be  used  either  for turning  pistons or boring cylinders to ensure  that  they are complementary with one another.

The longidudinal axis of the rear part is oriented toward the fifth metatarsus of the foot so as to likewise orient the calcaneus.  The median part has an inner border which concavely curves to wind around the patient's plantar arch.
