Abstract: The adhesive applying of marks (3; 3') from a foil in tape form to predetermined points on a substrate (1) which is printed with motifs (2) and is drawn at a predetermined rate of advancement through at least one adhesion station is performed by means of punches of the adhesion station raised radially above a punching cylinder. The punches have convex punching faces, which are parts of a larger cylinder jacket concentric to the punching cylinder and, during each adhesion phase, roll on an impression cylinder and transfer the marks (3; 3') to the substrate (1). The band speed of the foil may also be less than the rate of advancement. A hot embossing foil having an adhesive layer or an embossing foil without adhesive layer may be used as the foil, the device for applying the embossing foil to the substrate (1) having an applicator unit for adhesive upstream of the adhesion station (11 or 11') and a radiating station for activating adhesive layers.

Title: Purified quartz and process for purifying quartz
Inventor: LORITSCH KENNETH B
IPC: C01B33/12
Filed: 1990-11-20
Abstract: Quartz is purified by removing mineral impurities, particularly alkali metal impurities, from within the quartz crystal lattice structure. According to the disclosed process, quartz crystals are subjected to a pretreatment that removes surface bound impurities and then contacted with gaseous HCl at a temperature of from 800°C to 1600°C for a period of time of from a few minutes to several hours, thereby diffusing the mineral impurities to the quartz crystal surface where they form salts with chloride ion, removing the salts, and recovering the purified quartz crystals.

Abstract: It has been found that when layered preforms are being injection molded utilizing at least two materials, it is possible to maintain the same horizontal and vertical pitch of adjacent cavities as is possible when each mold cavity is being filled with a single material. Most particularly, it has been found that when the percentage of the material to be injected into a mold cavity is relatively high, it is possible to utilize a single metering pot (18) for four adjacent mold cavities (10). On the other hand, if one of the materials to be injected into a mold cavity constitutes a relatively low percentage of the volume of a mold cavity, it has been found that a small metering pot (40) must be provided for each of the cavities of the four cavity mold (10). Most particularly, with this combination, it is possible to maintain the pitch of the single material mold and thereby maintain the small size of existing injection systems as opposed to an increase in the pitch of the mold cavities which would increase the size of the mold structure.

Abstract: Prochiral ethylenically unsaturated substrates are converted to chiral epoxides by reaction with optically active hydroperoxides in the presence of transition metal catalysts. For example, chiral glycidol is obtained by asymmetric epoxidation of allyl alcohol using optically active ethyl benzene hydroperoxide and a titanium alkoxide/tartrate catalyst. The chiral epoxide products are versatile synthetic intermediates.

Abstract: The distributor body (1) comprises, at the front, an opener formed from rotors (3) equipped with teeth (4) and with cutting discs (5). A movable bottom (2) causes the cylindrical bale (B1) or parallelepipedic bale (B2) to advance towards the rotor (3) which opens up the plants and sends them towards a blowing device. Arms (23) actuated by a jack (26) carry a gripping pusher (21) capable of pushing the bales (B1, B2) into the distributor body and of closing the rear of the latter. A harrow (7) is fixed to the arms (23) in order to close the space above the rotor (3) partially when the arms (23) are in the low position. The harrow (7) comprises spikes (7b1) directed towards the rotor (3) and guide faces (7d) which guide the plants in their rotation generated by the movement of the movable bottom (2) and by the movement of the rotor (3). The guide surface (7d) belongs to a flat sectional iron bar defining a guard surface (7e) preventing the tooth (7b1) from penetrating deep into the trusses of unopened plants. The invention is used for minimising clogging and to make possible unclogging easier. <IMAGE>

Abstract: The subject of the invention is a novel apparatus intended for enlarging the ends of tubes which comprises a body (1), an expansion tool, a mandrel (2), a connecting link (3) and two handles, one (7) of which is solidly fixed to the body while the other (4) is connected to the said body by means of the connecting link which imparts to it a movable pointer bearing enabling it to transmit to the mandrel, to which it is connected by means of a direct articulation, an axial force which increases as the said movable handle approaches the fixed handle. Once the expansion of the pipe has been carried out, the mandrel is extracted from inside the set of jaws of the tool by means of the traction force which is exerted thereon by the movable arm which the operator brings back to its initial position. This apparatus makes it possible to produce the fittings required for connecting the copper piping of sanitary installations. <IMAGE>

Abstract: The signals are processed in blocks. When signals are coded and decoded in blocks, the limits of the blocks may be visible or audible during reproduction of certain picture or audio signals, causing interference. By post-filtering (471, 472, 473) transformed, quantized and inversely transformed signal scanning values in the coder, or transformed and inversely transformed signal scanning values in the decoder, the visibility or audibility of signal jumps at the limits of blocks can be reduced.

Title: Local intervention interactive system inside a region of a non homogeneous structure.

Abstract: An interactive system for a local intervention inside a region of a non-homogeneous structure, such as the skull of a patient, which is related to the frame of reference (R2) of an operation table, and which is connected to a reference structure comprising a plurality of base points. The system creates on a screen a representation of the non-homogeneous structure and of the reference structure connected thereto, provides the coordinates of the images of the base points in the first frame of reference (R1), allows the marking of the coordinates of the base points in R2, and allows the carrying out of the local intervention with an active member such as a trephining tool, a needle, or a radioactive or chemical implant. The systems also optimizes the transfer of reference frames between R1 and R2, from the coordinates of the base points in R2 and the images in R1 by reducing down to a minimum the deviations between the coordinates of images in R1 and the base points in R1 after transfer. The system also establishes real time bi-directional coupling between: (1) an origin and a direction of intervention simulated on the screen, (2) the position of the active member.
