Title: Sound absorbent layer beneath floating screed - having two or three plastics sheets spot welded to give air cushions
IPC: E04F15/22
Filed: 1974-01-31
Abstract: The sound absorption of a floating screed floor is improved by incorporating, below the screed, a double layer of plastics sheeting with spot or strip-welding or gluing between the two layers. The non-bonded regions form a series of air cushions, with no escape for the air. In a variant, a similarly constructed triple layer is used, giving two layers of air cushions, pref. circles of cushions, staggered in two layers. The cushions may be square or rectangular. The whole composite sheet may also constitute a humidity barrier. Where the available depth for the sound-absorbing layer is small, esp. less than 5 mm., the sheet should be used below a stiff e.g., concrete surface and an underlay of prefabricated units, e.g., chipboard or plasterboard. The thermal insulation effect is good.

Title: Rack drive for document conveyor - has rack of soft material to allow teeth to conform to drive gear
Inventor: NITKA EDMUND ING GRAD
IPC: B61C11/04
Filed: 1976-03-10
Abstract: The conveyor system operates with carriers running on shaped rails, with one or more power driven friction wheels and is used for movement of documents, or other material of similar dimensions. Spur racks are mounted in vertical or inclined rail sections, engaged by a gearwheel on the carrier. There is a run-in spur rack in the transitional area between horizontal and inclined rail sections. The run-in spur rack (EZ) is made from material which is elastically deformable, so that when the approach of the teeth of the gearwheel (ZR) is non-synchronous, its own teeth (Z) are deformed by these, with the return force making the cogwheel move into the synchronous setting. The spur rack tooth height may decrease towards the beginning of the approach spur rack.

Patent DE-2619453-A1 (DE)
Title: Concentrating filtrate after sepn. of saccharate in sugar prodn. - by freezing effected by evaporation of liquefied gas eg. isobutane
Inventor: KUBASIEWICZ ANDRZEJ DR ING
IPC: A23K10/33
Filed: 1976-05-03
Abstract: Liquid returned from the filter during the prodn. of sugar from molasses must be concentrated before use in the prodn. of alcohol or addition to animal feed. This is effected by introducing into the liquid a liquefied gas having a b.pt. 0 degrees C (e.g., isobutane, b.pt. -3 degrees C); this liquid evaporates and, as a result, the water is cooled to 0 degrees C and then partly frozen. The gas is condensed and recycled. The ice crystals are sepd., washed and used for direct cooling of the molasses when reacted into quick lime (to produce saccharate). The concn. of the returned filtrate by partial freezing is more expedient than the customary evaporation because the latent heat of water solidification is about one seventh of the evaporation heat. Moreover, there is no deposition of the solids on the appts., walls and the latter are not corroded. The process can be carried out continuously in a freezing column.
