Title: Continuous-flow water heater for coffee machines
Inventor: BLECKMANN INGO DIPL ING DR MON
IPC: A47J31/54
Filed: 1988-11-28
Abstract: Continuous-flow water heater for coffee machines, wherein the plane in which the axis of the water pipe lies is inclined by a few degrees with respect to the plane in which the axis of the pipe heater lies, and thus with respect to the horizontally lying metal plate. This results in improved operation of the machine, without gurgling noises and without unnecessary steam production.
Patent DE-3841308-A1 (DE)
Inventor: WESSMAN ROLF
IPC: H01J29/86
Filed: 1988-12-08
Abstract: A mesh filter for display terminals, especially television screens, is used to improve picture quality and reduce electro-static fields. The filter consists of a multi-piece frame 1 glued to a fine meshed and electrically conductive mesh 2. The frame 1 comprises several separate pieces spaced apart around the mesh 2. Each piece is individually attachable to the display terminal. Since the frame 1 is divided the filter may be folded providing for reduced packaging and handling costs. It also simplifies the fixing of the filter to the display terminal. <IMAGE>

Title: Light-sensitive element
Inventor: KANAI YUTAKA
IPC: G03G5/08
Filed: 1989-03-08
Abstract: A light-sensitive element is described which has, on a conductive substrate, a photoconductive layer of a material in which an increasing number of charge carriers is generated as the amount of light received increases, and a switching layer of a material which changes abruptly from a state of high resistance to a state of low resistance when an impressed voltage exceeds a threshold value. Due to the switching layer, blurring at the edges can be avoided as a consequence of the intensity distribution in the exposing light beam.
Patent DE-3908528-A1 (DE)
Inventor: GUENTHER DIETMAR DIPL ING
IPC: G05B19/404
Filed: 1989-03-16
Abstract: In order to minimize deviations from the desired contour at reversal points of a feed movement during machining of curved contours by means of controllable feed drives for axes which make angles with each other, a correction pulse is generated in function of the time at which the feed movement changes direction. This correction pulse is added to a target speed value which is transmitted to the feed drive. The time at which the correction pulse is associated with the change of direction of the feed movement can be chosen in function of the prevailing conditions. The amplitude of the correction pulse can be determined in particular in function of a quantity which is proportional to the load on the feed drive at constant speed.

Title: Process for sealing concrete filling nozzles, and apparatus for carrying out the process
Inventor: MOOSER WALTER
IPC: E21D11/10
Filed: 1989-04-07
Abstract: The process for sealing a concrete sealing nozzle on shutterings comprises the conventional shutting-off of the concrete filling nozzle by means of an impact slide, the closure of the concrete filling nozzle by a further device (1), the opening of the concrete filling nozzle by the impact slide and the displacement, behind the shuttering, of the concrete composition present in the concrete filling nozzle, to be precise until the displaced composition comes to lie flush with the concrete composition which is already in the shuttering. In order to carry out this process, use is made of a guide (1) which can be fastened on the concrete filling nozzle (5) by means of a quick-acting coupling (3) and guides a displacement piston (10) on a piston rod (9) which permits the displacement piston (10) to be pushed into the concrete filling nozzle (5). In the pushed-in end position, the front end side of the displacement piston (10) then lies in the same plane as the inner side of the shuttering (6), this also resulting, at this location, in a smooth concrete inner shell which does not require any further working. <IMAGE>

Title: Sub-munitions expelled from projectile - have braking parachutes with independently timed opening-release mechanism
Inventor: ZIMMERMANN MICHAEL DIPL ING
IPC: F42B10/56
Filed: 1989-10-28
Abstract: After conveyance by a projectile (10) into a target area, individual sub-munitions (11) are separately expelled and complete their descent while susoended from a parachute (12) providing braking action. Opening of the parachutes takes place over a range of times by release systems dependent on time-delay members activated when the sub-munition leaves its carrier projectile, e.g., by a mechanical sensor or electrical switch. Parachute opening may be facilitated by a pyrotechnic charge or by an air-cushion formed when external air enters from diffusor slots in the external casing for the sub-munition. ADVANTAGE - Individually operating and differentially timed release systems prevent mutual interference between sub-munition.

Title: Co-extruded plastic waste water pipe
Inventor: HETZENECKER HEINZ
IPC: B29C48/09
Filed: 1989-11-25
Abstract: A plastic pipe (P) for fluids is formed of a smooth inner pipe and an outer pipe with two different surfaces.  The two pipes are fused together into a single pipe. The outer pipe has alternating smooth and corrugated sections. The smooth section can be divided to form a pipe joint by expanding into a slightly larger dia.  socket. The sockets allow connection, both to the extruded pipe and to other traditional pipe systems. A process for mfg. the pipe sections uses two concentrically arragned devices which form the inner and outer pipes. A haul-off unit with rotating pairs of cheeks  forms the outer corrugated pipe.

Title: Modified, sugar-free coated popcorn prodn. - uses natural sweetener from sugar beet instead of sugar, vegetable fats and fruit flavours
IPC: A23L7/174
Filed: 1990-01-16
Abstract: In a process for prodn. of modified popcorn with a sugar containing layer, the raw corn is opened up by the effect of heat in the presence of the coating material.

During the process the raw corn is continuously stirred, together with the coating material, in a cooking vessel at 130-150 deg.C. When the corn opens up it is coated in the material which consists of the sweetener, vegetable fats and fruit flavours. USE/ADVANTAGE - The process produces modified sugar-free popcorn with a variety of colours and flavours and is particularly suitable for diabetics.

Title: Sepg. residues from plastic packs - by washing with suitable solvent, e.g. cyclohexane, and treating fractions to recover solvent and polymers
Inventor: STRICKER URBAN DIPL ING
IPC: B03B9/06
Filed: 1990-09-17
Abstract: Rsidues of material left in plstics packs are sepd. by the use of a suitable solvent in which the packaging polymer is insol., pref. a volatile satd. hydrocarbon and cyclohexane in particular. Existing designs of washing plant can be used for washing with cyclohexane given certain modifications, e.g. to ensure there is no chemical attack or explosion. Polymer residues themselves do not float in this solvent and this simplifies extn.. Contacts with this solvent need only be brief e.g. if paper labels have to be freed from the polymer 5-30 mins. are enough at room temp. or less at elevated temp.. Removal of cyclohexane from the plastics fraction is best achieved by heating and evaporating, as its b.pt. is only 80 deg C. The evaporated solvent is recovered. ADVANTAGE - Polymer is recoverd in a clean state suitable for recycling e.g. by fusion. In some cases the residues of the contents can also be obtd. in reusable state. The process is suitable for use with non-food types of packages. Washing with solvent instead of water has several advantages e.g. removal of grease, etc., aq. portions are sepd., satd. hydrocarbons are less reactive and hence not liable to react with the residues concerned, deep penetration, low energy consumption by low b.pt./vapour pressure, solvent recovery, residues concerned are partly recoverable.
