Patent DE-2844653-A1 (DE)
Title: Forming an end section on a plastic pipe - by thickening the pipe wall of the end section
Inventor: FABER RICHARD CHARLES
IPC: B29C57/00
Filed: 1978-10-13
Abstract: A thickened end is formed on a plastics pipe by heating the pipe end over a predetermined length and axially compressing the heated length in a mould cavity which is longer than the heated length. During an initial phase of the compression, the heated length is thickened and during a subsequent phase the adjacent section of the unheated remainder of the pipe is heated by conduction from the heated length. Thickened conditions are arranged so that the ultimate thickened length of pipe is slightly less than the length of the cavity.
Patent DE-2846576-A1 (DE)
Title: Production of coated strip material - has viscous coating deposited on tape and passed through control gap with second tape to produce two coated tapes
Inventor: HENKLER HERBERT DIPL ING DR
IPC: B05D1/00
Filed: 1978-10-26
Abstract: The production of tape with a surface coating is effected in such a way that the rate of mft. is improved and the depth of the coating maintained at a constant value. The carrier tape material (1) receives a surface deposition by spraying, or a similar process, as it is passed over a hardened roller. The tape is fed through a calibration gap (7) in a control plate (9). At the same time a second tape (2) is fed into the gap. As the material leaves the control gap the two tapes are separated each with a surface deposition. The use of the control gap ensures that the deposited material is a specified thickness. An alternative system collects a layer of the surface coating material, which is highly viscous, by rotating a partially submerged drum. A final pair of rollers separated by a control gap relives both the coating and two carrier tapes and produces two separate coated types.

Title: Pointing up paving, esp. natural stone - using setting retarder sprayed onto surface after pointing to prevent soiling
Inventor: BECKER RUDOLF DR
IPC: E01C5/02
Filed: 1979-11-07
Abstract: Pointing up areas of paving, esp. of natural stone, involves applying a fluid or moist mortar mix based on sand, cement and water, pref. by washing and sweeping into the joints. The novel feature is that, after this, the area is sprayed with a surfactive chemical setting retarder, which immunises the cement particle surface of the material and prevents the mix setting on the exposed areas of stone. The technique avoids soiling the surface, without impairing the quality of the pointing.

Title: Continuous washing off process for textile fabric - by passing between absorbent surfaces saturated with concentrated wash liquor
Inventor: BERGMANN GERHARD ING GRAD
IPC: D06B3/20
Filed: 1980-01-26
Abstract: In a washing-off process for continuous lengths of fabric following weaving, printing, etc., the fabric is passed between a pair of absorbent surfaces which are satd. with concd. solns. of washing agents. Mechanical action on the outer sides of the absorbent surfaces drives the wash liquor repeatedly through the fabric perpendicular to its direction of movement. The absorbent surfaces consists pref. of felt, pile fabric or foamed material, bonded to a base of carrier-material and formed into a pair of endless belts. The mechanical action on the fabric sandwich may be effected by passing it in zig-zag fashion around a series of staves or rollers. The process provides a rapid, intensive washing action for the removal partic. of mineral-oil stains from the fabric, using a high-concn. wash-liquor at a low liquor-ratio to minimise the consumption of expensive washing agents.

Title: Extracting heat from waste gas - using two heat exchange steps and avoiding prodn. of corrosive liq.
Inventor: BEN-SHMUEL DANIEL
IPC: F23J15/04
Filed: 1980-06-25
Abstract: Hot waste stack gas or flue gas having a particulate loading and contg. noxious prods. of combustion gases which, when exposed to cool heat exchange surfaces condense to produce active corrosive liq. is subjected to heat exchange to recover usable heat. As a first heat exchange step an aqs. liq. is brought into direct physical contact with the hot gas stream to extract heat, raise the temp. of the aqs. liq. and condense the stream by dispersing the particulate loading in the aqs. liq. and dissolving the noxious gases in it. A cool cleansed gas stream and a dirty heated liq. is produced. As a second heat exchange step the dirty heated liq. is cooled by heat exchange with a cooler fluid. Heat from the hot stack gas or flue gas is recovered without dirtying the cooler fluid or producing corrosive liq. from the noxious gases during the second heat exchange step.
