Patent EP-0011060-A1 (EP)
Inventor: MACULAN ALEXANDER DIPL-ING
IPC: F26B15/16
Filed: 1979-10-17
Abstract: 1. Apparatus for manufacturing elements, in particular building elements such as moulded blocks, from a plastic, gradually hardening mass, preferably concrete, furnished with a number of movable conveying devices between a starting station serving for moulding these elements and an end station serving for the discharge of the finished elements which are suitable for the reception of usually several elements at a time and equipped with loading compartments for this purpose which are at times air-conditioned during the course of the conveyance of the elements to the end station, characterized by the fact that solid walls of these individual conveying devices form loading compartments closed on five sides, whose open side within the conveying distance is temporarily coverable and lockable for air-conditioning the loading compartments either by means of a solid wall of a neighbouring, similar conveying device or by a separate, self-moving covering forming a unit with the conveying device or stationary walls.

Abstract: Une methode amelioree et un appareil pour former des feuilles de materiau thermoplastique est decrite dans laquelle une ou des feuilles sont moulees sous pression contre un organe de moulage par application directe d'un liquide de refroidissement sous pression a celles-ci. Le liquide entre en contact avec la surface de la feuille et lors de la diminution de la pression se vaporise et par l'effet de la chaleur latente de vaporisation absorbe rapidement une quantite importante de chaleur soustraite ainsi de la feuille. Il se forme alors une peau solidifiee a la surface exterieure de la feuille. Cette peau peut se former simultanement au faconnage de la feuille ou ulterieurement. La feuille demeure moins longtemps dans le moule dans la mesure ou elle devient plus rapidement apte a retenir la forme du fait de son refroidissement rapide. Ceci permet d'utiliser un equipement moins volumineux dans le processus de faconnage des feuilles. Cette reduction peut se traduire par une substantielle economie de prix.

Abstract: The invention provides a method of heat-treating a biaxially oriented polyolefin film by constraining the film against shrinkage, heating the constrained film to at least the minimum stress relaxation temperature of the polyolefin, and thereafter cooling the treated film to a temperature below the alpha-relaxation temperature of the polyolefin. 
     The film is preferably heated rapidly to the required temperature and cooled rapidly therefrom. The resultant films exhibit good modulus and thermal shrinkage characteristics. The heat-treatment may be supplemented by a conventional heat-setting operation to improve heatsea- ling characteristics of the treated films.

Abstract: A centrifuge tube holder (10) which not only provides support for the tubes (23) in a vertical orientation when placed on a workbench, but also horizontal and radial support when the tubes are placed in a centrifuge rotor. The tube holder has at least two sections (12, 14) which are pivotally connected to allow for upright or vertical orientation of the tubes when placed on a workbench. The two sections (12, 14) can be pivotally oriented with respect to each other to place the tubes horizontally in a centrifuge rotor at different radial angles with respect to each other with reference to the spin axis of the rotor. The holder (10) also incorporates means (40, 42) for securely holding the tubes within the holder (10) while they are being transported, so that the holder (10) can be inverted without the escape of the tubes (23). On the other hand, the biasing or securing means for the tubes in the holder is eliminated when the holder is at rest on the workbench to permit convenient and easy insertion or removal of the centrifuge tubes. The tube holders (10) act in conjunction with a spacer (70) within the rotor bowl to not only provide the proper placement of the centrifuge tube holders during centnfugation, but also permit extraction of the holders from the rotor bowl to remove essentially all obstructions within the rotor bowl for easier cleaning after a centrifugation run. 
     An alternate embodiment of the invention holds a plurality of small volume tubes in such a manner that, when the centn- fuge rotor is at rest, the tubes will be oriented at an inclined angle, but will assume essentially a horizontal orientation when the centrifuge rotor is operating. The holder (111) provides improved collar (142) support for the centrifuge tube (140) during centrifugation and also provides for the inclusion of a tube pivot point (126) in the plate to enhance the proper movement of the tube from its at-rest position to the correct support position during operational speeds of the centrifuge rotor.

Abstract: An oxide layer 104 is formed on a semiconductor substrate 101 by selective oxidation. Thereby the edges 104A of a window in the oxide layer 104 have edges which are naturally tapered. Using the oxide layer 104 as a mask, a buried layer 105 is formed by ion implantation. The buried layer is flat at the centre of the window, curves up to the surface of the semiconductor substrate 101 in correspondence to the tapered edges 104A of the oxide layer 104 and extends into the oxide layer 104. A part of the buried layer 105B is exposed by etching of the oxide layer 104, and a contact region 110 is formed at that exposed part.

Abstract: A circuit arrangement for transmission of communication with a laser diode by way of a light waveguide wherein it is desired to reduce the optical transmitted power of the laser diode in order to lengthen its life duration and wherein in a receiving device a control signal is generated and is then fed back to the transmitting device through a return channel to control the output of the laser diode as a function of the received control signal. The invention assures that the optical transmitted power does not overload the laser diode which results in a considerable increase in the operating life time of the laser diode. The circuit arrangement can be used in light waveguide systems for optical communication or data transmission systems.

Abstract: All components of arriving polarized waves are obtained independent of the type and amount of polarization. A higher mode detector (2. 3) outputs two higher mode components which are in orthogonal relation. These two components are combined so as to maintain the orthogonal relation. A circuit is provided having a set of at least one 90° phase difference plate (4) and one 180° phase difference plate (5) which have rotatable phase lag surfaces and which are cascade-connected. The 90° phase difference plate (4) is provided on the side of the circuit combining the two higher order components. The output of the 180° phase difference plate (5) is divided into first and second orthogonal polarization components. The first polarization component is synchronously detected with a local oscillator (9) output synchronous with (Ay) reference signals to provide a first angular error output while the output of the second polarization component is synchronously detected with signals shifted 90° in phase from the local oscillator (9) output to thereby provide a second angular error output (Ax) orthogonal to the first angular error output.

Abstract: An improved method of making a half-tone gravure printing plate in which a planographic or relief half-tone positive and a gravure screen are printed on a photosensitive resist forming material. In the method, the lowering of the quality of printed matter resulting from formation of moire pattern can be prevented and an error caused by the reproduction step between a new half-tone positive and an original half-tone positive can be corrected. The method comprises the steps of contacting and inverting the planographic or relief half-tone positive on a soft continuous gradation film to prepare a half-tone negative, screening in a photosensitive film with screen dots of the half-tone negative eliminated by use of a contact screen to prepare a new half-tone positive; printing the new half-tone positive on a photosensitive resist forming material to form an element of sizes of dots; and forming a space between the new half-tone positive and the photosensitive resist forming material, and printing said half-tone positive, blurring the screen dots, on the photosensitive resist forming material, thereby correcting an error of gradation of a middle tone portion.
