Title: Heat store comprising thin-walled polyethylene tube - almost filled with calcium chloride hexa:hydrate and sealed with same polymer caps (SE 1.12.80)
Inventor: CAMPBELL STEVE
IPC: F28D20/02
Filed: 1980-04-30
Abstract: A heat store unit is a long high-density thermoplastic tube e.g. polythene, partly filled with heat-storing medium e.g. calcium chloride hexahydrate whose phase can be changed, closed at one end, and round or oval in cross-section. The calcium chloride hexahydrate filling medium is produced at site by dissolving its dihydrate in water; with its formation the temp. rises to beyond its m.pt. so that it can be conveniently poured into the tube used. The polythene tubing used has a M.W. 500,000-700,000, it has an o.d. 8.5 cm, wall 3mm, it is closed off at one end with a screw cap of the same polythene. The filling is poured in until the tube is 90% filled. The top end is then sealed off by heating a similar top cap to 260 deg.C, heating the top end, and applying the top cap under pressure to weld it on. Resistant to medium used inside and to the surrounding environment, suitable for e.g. hot water/solar heating/heat pumps.

Title: Semi-automatic film splicer - has splicing tape indexed by lifting splice head past film position
IPC: G03D15/04
Filed: 1980-08-14
Abstract: The splicing tape is supplied mounted on a perforated carrier strip and is threaded to an indexing claw (31) on the top of the splicing head. The claw and drive mechanism is pivoted about an axis parallel to the head pivot axis and indexes the tape when the head is lifted higher than the normal raised position. The indexing control provides a separate operation and is not affected by pressing the head down. This allows the user to lock the head down for compact storage without damaging the tape and feed. The claw is operated by a two armed lever, with one arm linked to the claw and the other to the actuating control when the head is lifted.

Title: Ink fountain for printing machines
Inventor: JOHNE HANS
IPC: B41F31/04
Filed: 1982-03-31
Abstract: The invention relates to an ink fountain for printing machines having an adjustable colorimeter. The aim of the invention is to develop an ink fountain in such a way that the printing quality is decisively improved by preventing uncontrollably falsified colorimeter settings. Furthermore, the number of spoiled sheets in proof printing and production printing is to be reduced. The object on which the invention is based is to provide an ink fountain, by which a drastic minimisation of the force effects occurring in the ink fountain, along with an increase in the service life of the colorimeter and of a device for reducing damage to the colorimeter and/or ink ductor, is brought about by an optimum design and arrangement of the colorimeter in interaction with the ink ductor. For this, the colorimeter has a negative cutting angle, the functional faces of the colorimeter having a rounding radius of 0.05-0.3 mm in the direction of the ink ductor. <IMAGE>

Title: Roller-blind box and process for producing it
Inventor: BACHL KARL DIPL KFM
IPC: E06B9/17
Filed: 1982-04-23
Abstract: A roller-blind box having a casing (1) of a width (b) corresponding to the nominal thickness of the masonry, and especially made of breeze concrete, surrounds in one piece an insert body composed of heat-insulating material (6), such as foam. The heat-insulating material (6) leaves free a cavity (7) which serves for receiving the roller-blind skirt (9) rolled onto a shaft (8), and the vertical centre line (14) of which is offset relative to the vertical centre line (15) of the casing (1) in the direction of the outer wall (2) of the casing (1) by an amount (x) which corresponds at least to half the thickness (d) of the heat-insulating material (6) in the region of the inner wall (4) of the casing (1). This affords the most efficient possible heat insulation between the cold cavity (7) and the room side of the casing (1). The breeze concrete of the casing (1) fits homogeneously into the masonry and, by virtue of its one-piece design, presents a good base for plaster, wallpapers, etc. on the room-facing inner wall (4) and on the adjoining room-facing lower wall (18). The mounting orifice (16) for obtaining access to the cavity (7) can be shifted to the outside of the window (13), without relinquishing the width of the window sill. <IMAGE>
