PII: SO956-7135(98)00145-5 Production of frozen desert such as ice bar - involves forming frozen desert layer comprising food materials in random concavo.convex shape on edible core material mNEB0 FOODS LTD 96.08.07 9WP-225926 (98.02.24) A23G 9100, 9104, 9124, 9126 Production of a frozen desert such as an ice bar involves forming a frozen desert layer (2) on the periphery of a core material (1) comprising an edible material to form a frozen desert (5). At least two types of food materials are used in the surface of the frozen desert layer. Semi-frozen desert material is adhered to the surface of the core material to forming a random concave-convex shape. Then a viscous food material (4) is added and rapid freezing is effected. Advantage - Viscous food material may be partially adhered to the frozen desert layer to form a spots pattern. (6p Dwg.No.l/4)

PII: SO956-7135(98)00146-7 Defect inspection method for glass bottle storing alcoholic beverages e.g. beer, soy sauce - involves judging existence of defect in glass container based on image of container output by optical unit OJI KOEI KK 9608.26 9WP-223583 X25 (98.03.06) GOIN 21190 Addnl. Data: IMAMURA F (IMAMI) The method involves positioning a light source (14) in the upper part of a glass container (W) which is to be tested. The container is placed in an inspection area (PC), and light beam is projected onto the container. An optical unit (15) which is arranged on the slanting upper part of the container, obtains the reflected image of the container, which is rotated along the periphery of axle line part (CW). A judgment unit judges the existence of defect in the container based on output from the optical unit. Advantage - Detects existence of hair crack in glass bottle quickly, at low cost.

PII: SO956-7135(98)00147-9 Gas barrier material - exhibits good gas barrier properties under conditions of high humidity and is superior in clarity and melt mouldability. (Eng) KURARAY CO LTD 97.03.31 97JP-080919 (96.10.15 9WP-272250) 807 (A92) (98.04.22) CO8F 16108, 8104, 8112 97.10.14 97EP-117756 R(AT BE CH DE DK ES FI FR GB GR IE IT LI LU MC NL PT SE) A gas barrier material has an oxygen permeability not higher than 30 ml. 20 ~m/m*.day.atm measured at 20 degC, 100% relative humidity and comprises a polymer containing not less than 30 mol% of repeating unit of formula (I) Rl=l-2C alkyl; R2=H or l-3C alkyl. Also claimed are: (1) a gas barrier shaped article comprising the gas barrier material; (2) a packaging material comprising the gas barrier material; (3) a multilayer structure comprising layer(s) of the gas barrier material; (4) a multilayer material comprising a layer of

thermoplastic resin lamianted on one or both sides of a layer of the gas barrier material; (5) a multilayer structure having layer(s) of thermoplastic resin selected from polyolefin, polyamide, polyester, polycarbonate, polystyrene, polyvinylchloride, and polyurethane, laminated on one or both sides of a layer of the gas barrier material; (6) a packaging container comprising the multilayer structure of (3) to (6); (7) a multilayer film with a total thickness of lo-300 pm, having layer(s) of thermoplastic resin(s) specified above in (5) laminated on one or both sides of a layer of the gas barrier material, the layer of the gas barrier material having a thickness of 0.5-50 pm; and (8) a packaging container comprising the multilayer structure of (7). Use - The gas barrier material is useful for packaging foods such as edible fats and oils, processed meat or marine products, pickles, ketchup, seasonings, coffee, spices etc and medicines and toiletries, cosmetics and agricultural chemicals. Advantage - The gas barrier material exhibits very good gas barrier properties under conditions of high humidity and is superior in clarity and melt mouldability.
