Abstract: MOUNT FOR A PARABOLIC ANTENNA            ABSTRACT OF THE DISCLOSURE          A mount for a parabolic antenna includes a ver-tical post with a beam pivotally mounted on the post about a horizontal axis and lockable in a desired elevational position by the cooperation between a pair of slotted plates and a nut and bolt which passes through the beam. The beam is then coupled to a frame for supporting the dish by an upper and lower bearing.  The distance bet-ween one of the bearings and the frame can be adjusted to change the angle between the frame and the pivot axis. A screw arrangement attached to the beam and to the frame can be manually operated to pivot the frame about the pivot bearings. Adjustment of the angle of the frame to the beam and the angle of the beam to the post can set the dish so that operation of the screw scans the dish through the required scanning arc.

Abstract: ABSTRACT The coded data (12) on the record carrier (10) and the method for encoding such data (12) in tracks (14) provide a relatively simple and yet very effective means for making the data record carrier (10), and particularly the data (12) recorded thereon, highly tolerant of errors such as "burst errors" where one or more spots of data on the data record carrier (10) arc ooliterated,  The data (12) is recorded on the data record carrier (10) in arcu-ate nested tracks (14), each track (14) comprising a stream of data bits.  The stream of data bits includes an encoded front track address (32) and encoded back track address (44) with coded groups or so-called Hamming type co-ded groups (52) of data bits therebetween each of which can comprise 96 or 105 data bits.  Error correction is provided by including in the coded groups data words which include a data byte and a field of parity bits, typically an eight bit data byte followed by a four bit parity field. also a cyclic redundancy checksum byte is provided in the group as a further check of the data therein.  Further, this data is multiplexed.  Additionally, one or two redun-dant groups are provided in each track (14) for recreat-ing missing groups and a cyclic redundancy checksum field is provided for error detection in each track (14).

Abstract: Abstract:    A novel cover arrangement is described for use with foodstuff holding pans to be heated in a microwave oven. The cover is one which in terms of microwave energy, does not transmit reflected energy.  Thus, the cover acts in a manner analogous with non-reflecting coatings in optics and permits passage of the microwave radiation into the container holding the foodstuff, while substantially pre-venting escape of microwave radiation reflected from the foodstuff surface and container bottom.  In this manner the microwave energy is retained and concentrated within the container, resulting in more efficient and uniform heating of the foodstuff.  The novel cover is particularly valuable when used with aluminum foil pans, which without the cover of this invention seriously reflect microwave radiation.

Abstract: ABSTRACT OF THE DISCLOSURE:            Polyphenylene oxide is a valuable thermoplastic polymer blended with polymers and copolymers of styrene.  It is obtained by means of the oxidative polymerization of 2,6-xylenol.  However, prior homogeneous phase processes suffer from viscosity problems, while prior heterogeneous processes involve uneconomic batchwise production modes.   A process for the production of polyphenylene oxide which overcomes these difficulties involves the oxidative polymerization of 2,6-xylenol,  with either oxygen or a gas containing molecular oxygen,  in  the presence of a  catalyst,  by continuously operating in a circulation system, and with the precipitation of the polymer in the liquid reaction medium.

Abstract: ABSTRACT OF THE DISCLOSURE       The  method  relates to manufacturing contact  spring sockets with a plurality of radially inward bowed contact springs  (9) clamped at one end in an approximately cylindrical socket body (1),  formed by a thin-walled deformable sleeve. The straight contact  springs, formed by sections of a contact spring wire, are  introduced into  the socket body and made fast at their front ends to a central  head (10)  at the front end  of  a  line  connector  (2) by  deformation of  the socket material.   The free ends of the contact springs (9) are  brought into supporting  abutment  on  an  annulus  (5) at  the pin  insertion end.          Deformation of the socket body (1)  to produce  bowing of  the contact springs can be omitted if in accordance with  the invention  an insert ring (6) is introduced into the middle region of the socket  body (1), which fits adjacent the interior wall of the socket,  subsequently the contact springs (9) are introduced into the socket body,  whereby they lie  adjacent  the  insert ring   (6),  and  following   on   this  a mandrel (12), which is conically shaped  and whose  diameter increases towards its front end, together with the annulus (5) mounted on it, is introduced  into the  socket body  (1) and again withdrawn  from the socket body with radial expansion of the annulus (5) which  is secured against  axial  displacement during this while  carrying with  it the outer ends of the contact springs, and finally the central  head (10) is deformed while carrying with it inner ends of the  contact springs.

Abstract: ABSTRACT OF THE DISCLOSURE     A   rotary workpiece   treating   apparatus   is   described particularly useful for depositing coating or adhesive materials within threaded fastener nuts.  The device includes a continuously rotating turntable assembly having a plurality of workstation cylinders attached thereto.   Installed within  the  cylinders  are  plungers  having  cam followers, which plungers move between a first and second position as the turntable assembly is rotated.  A probe attached to the plunger is caused to enter within the internal bore of the nuts and release flowable  material within the nut.   The  flow of  such material  is controlled by a valve stem protruding from the probe which is depressed against a stop surface when the probe is inserted within the nuts.  A second clamping plunger within the cylinder clamps against the nut when the probe is being inserted, thereby positioning the nut and preventing flowable material from being deposited on the exterior surfaces of the nuts.   The clamping plunger further  acts  to prevent  discharge of flowable material from the probe when a nut is not positioned at the workstation position.
