Abstract: ABSTRACT OF THE DISCLOSURE:           The invention relates to a ventilation unit in a frame or the like, the said unit comprising a flow-duct and a slide having a leg which opens and closes the said flow-duct, the said slide being adapted to move at least partly back and forth in the said flow-duct, a stop-surface being associated with the leg which possesses a sealing surface.  A ventilating unit of this kind is fitted, for example, in a window-frame or an opening in a wall, the slide providing a satisfactory seal in the closed position, since a major energy loss would otherwise have to be feared.  The ventilation unit is to be reliable in operation and to provide reliable sealing.  In order to solve this problem, it is proposed that the slide be substantially U-shaped, a second leg having a sealing surface being provided in the flow-duct.   This second leg extends over a portion of the structural height of the said flow-duct and a stop-surface is associated with seal-ing surface of the said second leg, a guide-element for the slide being provided on both longitudinal sides of the said flow-duct.          The ventilation unit according to the invention thus comprises at least two sealing surfaces, so that, when the slide is closed, satisfactory sealing is assured.  The slide is furthermore reli-ably guided in a simple manner by the said guide-elements, thus ensuring great reliability.

Abstract: ABSTRACT:          "Process for the separation of methyl tert-butyl ether from reaction mixtures containing it".       Methyl  tert-butyl  ether  (MTBE)  is prepared by the  selective  reaction  of  methanol  with  isobutylene contained  in a hydrocarbon fraction with four carbon atoms (C4fraction, or C4hydrocarbons), operating in the liquid  phase  under  the  influence  of  acid  catalysts.          The reaction mixture containing MTBE together with me-thanol and C4 hydrocarbons is distilled, preferably at increased pressure, with separation of the methanol and the  C4  hydrocarbons at  the head and of MTBE at  the bottom of the distillation column.   This operation is carried out with an additional lateral liquid flow of a C4 hydrocarbon, or mixture of C4 hydrocarbons, to the column so as to maintain a methanol-C4 hydrocarbon com-position in the column at all times with a greater than azeotropic  C4 -hydrocarbon  content  at  the  operating pressure.       According to a preferred embodiment the distil-led C4-hydrocarbons,  after separation from the metha-nol, are recycled as the lateral flow to the distillat-ion column.   It is thus possible to separate MTBE com-pletely in a single distillation operation with a high purity  as  the  product  at  the  bottom  of  the column.

Abstract: ABSTRACT OF THE DISCLOSURE     The disclosure herein describes an incident which is subdivided into two components having orthogonal polarization states and these two components form the object of a coherent detection. For this purpose, a local oscillator supplies a local wave, which is itself divided into two components having orthogonal polarization states, which supply two detection - demodulation channels. The demodulation signals of these two channels are combined, and in particular added, and the resulting signal makes it possible to recover the information independently of the polarization state of the incident wave. The invention applies to optical transmission.

Abstract: Abstract Machine for lasting heel seat  portions of shoes In a tack seat lasting machine the wiper plates (90) first effect an "advancing + inwiping" movement and thereafter an "inwiping only" movement, while a central wiping member (76), about which the wiper plates pivot, advances only.  To achieve this motion, the member (76) is supported by an arcuate projection (78) which is accommodated in grooves (83) formed in the wiper carriers (88), the center of curvature of the projection and grooves coinciding with the axis of the wiper plates.          Thus, the central wiping member is always brought to the same "back tack" position (but the shoe can be adjustably positioned relative thereto by varying the fore-and-aft position of the heel band (20)).          The nail pattern is adjustable, without affecting the back tack position, by limiting the stroke of the cylinder controlling the operation of the wiper assembly.

Abstract: Abstract of the Disclosure A process for fabricating a cross rolling die which substantially reduces the time, expense and complexity heretofore encountered in such machine component fabrication is disclosed.  A flat wooden cross roll tooling model blank cut to the specified die dimensions is positioned on a mill mounting table.  The surface of the wood blank is then milled by a conventional milling machine to produce a pre-form blank in accordance with the desired cross roll die surface.  A face cast of the thus contoured wooden model blank, or a negative impression, is then made which, in turn, is used to make a positive cast of the wooden model blank.  A series of closely spaced cuts parallel to the axis of roll is then made in the wooden model blank and the positive cast of sufficient depth to provide radial flexibility in each of these pieces.  The model blank is then divided into appropriate segments for separate mounting on the cross roll die mounting plates, with each segment mounted separately so as to cover approximately 315  of the full 360  displacement of the cross rolling machine.  The transverse cuts in the wooden model blank and positive cast are then filled with a hard-setting filler material and the surfaces of the model blank and positive cast are then contoured such as by grinding down.  A sand cast is then made of each segment from which corresponding face casts are made.  Abrader die casts are then in turn made of each face cast.  A graphite electrode is then abraded on each abrader die and a cross roll die blank is then formed by means of electrical discharge machining (EDM) from which the cross roll die may be formed.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an injection molding system of the type wherein a heated probe is centrally located in the hot runner passage.  The probe has a pair of circumferentially spaced melt channels, each with an upstream portion which branch out from a common central inlet to a downstream portion along the outer surface of the probe.  The probe is seated in a well in the cavity plate and a hollow cylindrical insulating sleeve is located between the downstream portion of the probe and the wall of the well.  The outer surface of the probe and the inner surface of the insulating sleeve have longitudinally extending grooves which are aligned to form the downstream portions of the melt channels.  The insulating sleeve is formed of a thermoplastic material with low thermal conductivity and a high melting temperature.  In addition to insulating, the sleeve provides the advantage that it avoids the space between the probe and the well wall filling with melt which often results in problems on colour changes and the degradation of the stagnant material which is trapped.
