IPC: B29C49/06
Filed: 1996-07-16
Abstract: The machine for the production of receptacles of plastic material comprises a loading device (5) in which the preforms (2) are disposed neck down on supports (7) of double carriers (8) heated in a heating device (10) and moved into a drawing-blowing device (12). In this latter, the receptacles are formed and then discharged into a discharging device (14). In the part (21) of the guide track (20) the supports (7) and the preforms are aligned in a single row, whilst in the part (22) the supports (7) and the preforms are arranged in a plurality of parallel rows. Between each row of preforms of a row of carriers (8), the heating device (10) comprises a heating body (42) arranged so as to heat bidirectionally the preforms located on each side of the heating body (42). The heating device can moreover be raised from an active position to an inactive position and vice versa. There is thus obtained a machine with a very high output, of reduced size and low consumption of energy.

Abstract: <PICT:1107305/C6-C7/1> A dielectric body has conductive regions formed therein by selective reduction.  The invention is described with reference to the reduction of a crystalline compound of formula Mx Y3- x Aq Fe5- q O12, wherein M is selected from the group consisting of aluminium gallium, indium, thallium, lanthanum, scandium and the rare earth elements, and x is any number between 0 and 3; wherein A is selected from the same group of metals and q is any number between 0 and 5; and wherein x is always less than 3 when q = 5 and q is always less than 5 when x = 3; and in particular yttrium iron garnet, Y3 Fe5 O12, (YIG).  Other compounds which may be used include spinels, hexagonal iron oxides, and perovskites.  The degree of conductivity attained depends upon the intensity and duration of the reducing reaction.  Fig. 1 shows a YIG body the surface of which has been reduced in a hydrogen atmosphere. Inner region A comprises unreduced YIG having a resistivity of about 1012 ohm-cm. while surface E consists almost entirely of metallic iron; intermediate layers B, C, D are of progressively higher conductivities.  Regions of limited conductivity, e.g. to form resistors, are produced by partial reduction.  Surfaces may be metallized by reduction prior to the plating thereof, e.g. with nickel, by an elctroless process.  Electroless plating of nickel may be carried out in a solution containing the following percentages by weight:- .NiCl2 . 6 H2O.3% .NaH2 PO2 . H2O.1% .Ammonium chloride.5% .Sodium citrate.10% .Water.81% Ammonium hydroxide is repeatedly added to the solution during plating at 95 DEG C. for half an hour.  Other metals, such as silver, may be deposited be electroless plating on the reduced surface.

Title: Membrane filter unit - with sector-shaped section membranes
Filed: 1974-07-03
Abstract: In a membrane filter unit comprising a pressure resistant envelope, the cross section of which is filled with filtration membrane surfaces having wedge-shaped cross section, the membrane surfaces being mutually separated by a porous layer, the tops of the apices of the sectors comprising the tubular filter membranes of sectional cross section, are interconnected in the centre of the envelope, support the curved end walls on the cylindrical inner wall of the envelope and the side walls of the sector support each other from the centre to the inside of the envelope. The risk of damage to the membranes is reduced by mutual support provided by the sector-shaped filtration membranes and associated fibre fleece material, and locating of the membranes within the envelope is much easier since no central tube is required.

Title: Method for compressing flat wooden elements - involves pressing between two movable plates, one having elastic layer to receive knot which projects after pressing
IPC: B27M1/02
Filed: 1981-10-08
Abstract: The method involves introducing a board (8) between a stationary plate or table (2) and a press plate (3) which is vertically movable. The board rests on an elastic bed (7) and is subjected to a press force via the press plate. The applied pressure is in the range of between 20 and 60 MPa. The material of the elastic bed (7) is able to accommodate the projecting portion of a knot (9) without the knot being splintered. The soft wood board (8) will thus be permanently compressed while the knot will be partially projected. This facilitates the removal of the knot by grinding after the compression operation.

Patent NL-8601447-A (NL)
IPC: H04N7/50
Filed: 1986-06-05
Abstract: In a method of recording video information in a record carrier (10), each picture (1) of NxM picture elements being divided into subpictures (2) of nxm picture elements, the video information of each subpicture is encoded in accordance with a transform coding (Ti) and recorded on the record carrier. Moreover, corresponding subpictures 11.1, 11.2, Fig. 4a) of two pictures (B1, B2) are compared with each other. To both subpictures a motion code (mci) is assigned, which motion codes are the same if the subpictures do not differ substantially from one another, but which are not the same (mc1, mc2, Fig.4c) if the subpictures (16.2, 16.3) differ substantially from each other. The motion is recorded on the record carrier (10) together with the coded information of the subpicture. Moreover, different transform codings (T1, T2, Fig.4a) may be applied to the subpictures. A higher-order transform coding yields a more accurate information of the subpicture which is encoded (Fig. 3). The associated transform code (Ti) is also recorded on the record carrier (10). Further, a method of reproducing video information from the record carrier (10) is described (Figs. 5, 6) and apparatuses for carrying out the two methods are described (Figs. 7 to 11).
