Title: Volatile vapours, esp. benzine, sepn. from air - during e.g. tanker discharge, using liquefied gas for pptn
Inventor: POHL KURT MANFRED DR ING
IPC: B01D5/00
Filed: 1974-03-11
Abstract: Air-vapour mixts. expelled, e.g. from storage and tanker filling or emptying processes for volatile liqds., are purified by cooling the air-vapour mixt. by in direct contact with liq. having a b. pt. below -75 degrees C, to ensure >=90% condensn. of the contained vapours; sepg. the condensate and opt. returning it to the storage tank, while the air is discharged to atmosphere. The refrigerating gas used is esp. a harmless one, e.g. liq. N2 or liq. CO2. Where direct contact with the refrigerating liquid is employed, the purified air, before discharge to atmosphere, may be used for pre-cooling the mixt. entering the system; in partic., this air may be diluted to raise its temp. so that the mixt. entering the system is not pre-cooled below 0 degree C, thus preventing pptn. of ice. In the indirect contact system a regenerator cycle comprising two or four stages may be used. Used esp. for purifying the discharge for example where air is expelled from a large tanker during a period of 12 hrs.; the very large quantity to be treated would necessitate a cooling plant of uneconomically large size, whereas the use of a refrigerating liquefied gas makes the treatment economically possible. In addn., the direct contact system causes the small proportion of water vapour in the mixt. to be pptd. directly as ice, thus preventing icing up of the equipment.

Title: Emptying sand traps in sewage purification installations - sediment rid completely of floating matter in bridge-mounted vessel
Inventor: BAEHR ALBERT
IPC: E03F5/14
Filed: 1974-03-26
Abstract: Sand traps in sewage farms, comprising deep narrow gulleys at the bottom of water courses, are cleared by pumping the mixture of suspended and precipitated matter with water, into a vessel arranged on a mobile bridge above the trap, where it is washed and dewatered by the action of agitators with lift, turn and deposit it repeatedly. The bridge, moving on runnersrs with guide rollers, carries a submersible pump delivering the sand mixt. via ducts tangentially into the vessel. This is formed by a section of a cylinder in which a worm conveyor runs in one direction to agitate the contents until the trap is emptied and then in the other to eject the sand through an outlet. Process gives a more thorough washing of the sand, a shorter waiting time for dewatering and a structure much lower in height.

Patent DE-2421413-A1 (DE)
Title: Exposure of colour TV tube screens during mfr. - using second ultraviolet lamp behind glass screen to reduce exposure times
Inventor: BRINTON BERNARD M
IPC: H01J9/227
Filed: 1974-05-03
Abstract: In making the luminescent screen, a film of polyvinyl alcohol and ammonium dichromate is exposed through a shadow-mask using UV light which makes the exposed zones insoluble in water, a typical exposure time being 8-10 mins; during this relatively long time scattering of the light occurs at the edges of the zone. By locating a second UV lamp on the other side of the screen, i.e. so that its rays pass through the glass, a brief back-exposure (e.g. 30 secs.) ensures that the entire thickness of the film is made insoluble esp. at the junction of the film with the substrate, and the exposure time of the main lamp (i.e. the one working through the shadow mask) can be reduced to 4-5 mins. so that in addn. to time saving, light-scatter is less. The exposure for the three primary colours is made in the usual way.
