Title: Polypropylene film - contg finely dispersed micro-particles of a thermoplastic
Inventor: MATSUI TAKESHI
IPC: B29C48/08
Filed: 1972-09-12
Abstract: Polypropylene film contains 0.01 to 1 wt %, based on polypropylene, of a synthetic thermoplastic resin having a pt. of higher than that of polypropylene and substantially little compatibility with polypropylene upon being melted is dispersed in the form of finely divided particle.

Title: Cold sterilizing and filling of bottles - by acid and water sprays and filling spiders with differential inclination
IPC: B67C3/18
Filed: 1973-03-28
Abstract: In an automatic cold sterilizing and bottle filling plant, esp. for wine, a spider with e.g. 32 arms holds the bottles in an inverted position for sterilizing sprays of sulphurous acid and rinsing sprays of water. After dripping dry the bottles are inverted and are filled by an inclined spider with filler tubes and nozzles. The inclination of the spider lifts the nozzles clear of the filled bottles which can be removed and replaced by empties. This plant guarantes sterilization combined with acid removal by rinsing. It requires not more than two operators and is simple to operate. The plant is inexpensive and portable so that it can be moved from vineyard to vineyard.

Patent DE-2361790-A1 (DE)
Title: Double railway track in tunnel - is lowered for electrification by using stabilisation struts and injected mortar
Inventor: LORCH OTTO
IPC: E02D17/04
Filed: 1973-12-12
Abstract: The lowering process is used for ensuring a correct distance between the overhead power cable and the rails when the double track railway is converted to electric operation. In tunnels and in some open stretches it may not be possible to raise overhead cables to the required height and hence the track has to be lowered. The lowering process is carried out while one track is free for traffic. The track rests on firm rocky ground and the lowering operation of the track with the sleepers and the rail itself starts by clearing away ballast and reinforcing the ballast for the other track with rails by vertical steel struts and injected mortar. The first track can be removed and excavated after stabilising the second track.

Title: Air filter with elements at an angle - having inclined or zig-zag configuration which can have electrical charge
Inventor: JUNG ANTON L DIPL ING
IPC: B01D45/04
Filed: 1974-03-18
Abstract: Air filter has several plate draped or zigzag elements arranged at an acute angle to the direction of flow. Between neighbouring elements is a free passage for the air flow and in sharp zig-zag configurations this is also zig-zag. In a further alternative, the zig-zags can be arranged so that the air passage consists of a series of wide sections and constrictions. The filter elements rely on a combination of gravity and electro-static separation and for this purpose conducting filter mats with a miner metallic layer and an outer filter material coating can be used. Alternatively, filter mats of a metal mesh can be used. The filter is used for air filtration where low pressure drop is important.
