Title: Multiple path lens for electron beam writing device - has two perforated magnetic plates spaced and combined with focusing system
Inventor: ANGER KLAUS DIPL ING
IPC: H01J37/317
Filed: 1980-03-20
Abstract: The multiple path lens for focusing a number of parallel beams of radiation for an electron beam writing device for forming a number of identical patterns on a semiconductor wafer in the production of integrated circuit clips, consists of two parallel perforated magnetic plates (1,2). The holes through the plates are in line and the plates can be permanent magnets. They can be of ferromagnetic material and form part of a large magnetic lens (10) with a winding (11) enclosed by an iron casing (12). The magnetisation can be varied by altering the current flow through the winding. In another design, one plate is stopped, having holes of different lengths through it, the spacing between some of the holes in the upper plate and those in the lower plate varying to give a variable magnetic force for correct forcusing. The writing device may use a hybrid lens with the radiation source near its front face, below a condenser lens and a deflection system.

Title: Switch for optical connections between light conductor pairs - has sliding block between main conductors carrying parallel and crossed-over lengths of light conductors for diverting light signals
Inventor: HALTENORTH HELMUT DIPL ING DR
IPC: G02B6/35
Filed: 1980-03-31
Abstract: The light conductor changeover switch (4) consists of two carrying plates (3), mounted on a common base (11), each plate (3) having a pair of parallel grooves, into which, the pair of light conducting cables are fixed with an adhesive. The carrying plates (3) are by a switch unit (5) carrying two short pairs of light conductors (6), one pair parallel and the other pair crossed, the distance between the ends of each pair corresponding to the distance between the main conductors (1) on the carrying olates (3). The switch unit is movable across the base plate (11), in either direction, allowing the parallel or crossed lengths of conductor (6) mounted on it, to match up with the aligned ends of the main conductors (1). Thus the signal carried by the light conductor pair (1), can be transmitted straight through the switch unit (5), or diverted to each opposite outgoing conductor (1).

Title: Mfg. plastics bag with printed legends from double layer sheet - with simultaneous printing then folding and sealing in single device
Inventor: JOERGENSEN LEIF BANK
IPC: B31B50/88
Filed: 1980-05-07
Abstract: A method of making plastics bags from double-sheet material by simultaneous printing on both faces, followed by sepn. of the sheets and folding each sheet and cutting it to produce separate bags from each, is carried out as follows. One of the printed and sepd. sheets (3) is folded to a V-shape with its printed legend outwards and fed directly to a single- track bag welding (sealing) appts. (11), while the second sheet (4) is reeled onto a storage roll (8); this second sheet is later pulled off this storage roll, folded into V-shape with the printed legend outwards, and supplied to the same bag welding appts. (11). With this arrangement the double speed of printing obtd. by simultaneous application of the printed legends onto both sides of the double sheet is combined with the advantage of using only a single bag welding appts. (11). This is made possible by the intermediate storage of one sheet (4) on the temporary storage roll.

Title: Self adhesive strips cut from fully coated sheet - with alternate bands of adhesive transferred to completely uncoated sheet
Inventor: WERNY LOTHAR
IPC: C09J7/21
Filed: 1980-07-19
Abstract: A method of producing self-adhesive strips operates on the principle of fully coating a sepg. paper with adhesive, removing strips of the adhesive, and slitting the sepg. paper with a series of parallel cuts, each down the middle of one of the bared zones. Two feeds of separating paper are used: the first of these is fully coated with adhesive, while the second is completely uncoated; the coated sheet has the coating lifted along parallel strips preparatory to baring its surface along these strips, then the two sheets are together fed and brought into contact in the contact zone the lifted strips of adhesive from the coated sheet are transferred onto the uncoated sheet so that the two sheets leave the contact zone each possessing a series of parallel adhesive strips alternating with parallel strips comprising no adhesive. The sheets are each longitudinally slit with a series of parallel cuts so that adhesive strips possessing adhesive up the centre but not along the edges are produced from both. Pref., the contact zone is produced between a pair of rolls and the sheets of paper leave these rolls at a diverging angle of 90-180 deg. The strips of sepg. paper each with their narrower layer of adhesive can be used for various subsequent purposes; esp. for pressing onto a support tape or strip, when the sepg. paper then fulfils the function of a protective covering to be later stripped off and thrown away.

Patent DE-3034960-A1 (DE)
Title: Electrostatically spun polymer fibre with porous foamed surface - and pore-free core, for clothing, absorption filter, or sound damper
Inventor: SCHMIDT KLAUS DIPL PHYS DR
IPC: D01D5/34
Filed: 1980-09-17
Abstract: An electrostatically spun fibre of a polymeric material has a very porous surface structure and opt. a band-shaped profile. The polymer has an amorphous or partially oriented molecular structure. The surface structure is a component of a foamed layer, which surrounds a fibre core which is free from pores. The foam layer is very uniform in thickness, and size and distribution of the pores. It is formed from the same material as the fibre core, but has a considerably lower degree of molecular orientation, which favours the heat-welding of adjacent fibres. The pores may be open or closed. Open pores pref. have constant cross-section, are arranged at right angles to the surface, and completely penetrate the layer. Pores of this type are pref. for the infiltration of cleansing or disinfecting cpds., which widens the scope of use of the fibres in textiles. The fibre has greater strength (e.g. 2-5x that of known electrostatically spun fibres), better pore structure, better dyeability, and greater resistance to rubbing.

Title: Mine roller cutter machine curved loading plate - has base and telescopic segments geared to move mutually and relative to machine
Inventor: KOPPERS MANFRED ING GRAD
IPC: E21C25/14
Filed: 1980-10-01
Abstract: In a loading plate assembly on a cutting machine in a mine, the shell-type plate partially encloses a raisable and lowerable cutter roller, and is repositionable by a hydraulically activated setting cylinder on the peripheral side of the roller. The plate (19), connected to the machine body (9) by the setting cylinder (25), is divided into a base segment (20) guided on the roller carrier arm (7), and a telescopic segment (36) guided on the base segment. When an arm lifting movement takes place, the segments are movable, by a gear coupling (31), relative to each other and to the machine body. Segments can be guided on sliding guideways. This ensures that minerals can be completely loaded into the conveyor, from a cutter roller working at the top.

Title: Process for the preparation of high-quality fatty acid esters
Inventor: MATSUKURA TADAAKI
IPC: C11C3/10
Filed: 1981-02-26
Abstract: The invention relates to a novel and highly effective process for the preparation lower alkyl esters, for example methyl esters, of fatty acids which are of high quality with regard to colour and odour and which are suitable for the preparation of high-quality soaps, even without further purification by graining, which has previously been considered as unavoidable in conventional processes. In the process according to the invention, natural oils or fats are used as starting materials, and these are reacted in a two-step transesterification reaction with a lower alkanol, such as methanol, to give the corresponding lower alkyl esters of the fatty acids, from which traces of coloured or chromogenic impurities are removed by adding an adsorbent, the nature of the adsorbent and the temperature and duration of the adsorption being important for an effective decolorisation. The best results are obtained using mixtures of activated clay and active charcoal in certain ratios by weight.
