Title: Periodic detonating combustion process - using separating zone of cooled combustion prods. from previous cycle
Inventor: WALAEW ALEKSANDR ALEKSANDROWIT
IPC: F23R7/00
Filed: 1973-10-19
Abstract: Combustible mixture is periodically detonated and combusted in a chamber, to which fuel and oxidant are fed separately. A separation zone of incombustible material separates the hot combustion prods. of the previous cycle from a newly fed charge of mixture, and is cooled to a temperature below that of the combustion prods. of the previous cycle. Preferably the separation zone is produced by cooling the combustion prods., which are compressed impulsively into the feed ducts by a short-time rise of pressure in the combustion chamber by detonating combustion of the mixture, below the ignition temperature of the mixture. Appts. may be used for MHD electricity generation, or production of periodic light, strong density fluctuations, or combustion in internal combustion engines.

Title: Refuse disposal bag dispenser - folds bags in three and rolls them while each bag overlaps another
Inventor: HECKRODT WILLIAM F
IPC: B65D83/08
Filed: 1974-06-19
Abstract: The bag dispenser system for plastic bin liners etc. is easy to handle and to store while the individual bags are arranged in an overlapping sequence so that they may be rolled up in a cylindrical roll, while the bags remain separate and unperforated. The bags are about 1m long and 800mm wide; to reduce the size to manageable proportions, they are folded in three. As the bags are overlapping there is no problem of air bubbles forming in the rolled bags because air is expelled during the rolling process. The overlap should be 50 to 60 per cent of the bag length to prevent the bags slipping past each other, while maintaining the desired degree of rotation.

Title: Elastic foam mouldings mfr from thermoplastics granulate - by filling mould with granules, compressing charge, heating and glueing granules together
Inventor: KRUG HANS DIETRICH DIPL PHYS D
IPC: C08J9/22
Filed: 1974-08-02
Abstract: Elastic foam mouldings are prepd. by heat-welding or glueing the plastics granules in a mould, the foamed granulate being charged to the mould, compressed, and heated until sticky. The process is performed in one operational step. A suitable steam-permeable mould is connected, at its top, with a refill or replenishing space, introduced into an autoclave and there subjected to steam pressure in such a way that the temp. of the satd. steam reaches the temp. at which the resin becomes sticky. At the same time, the granulate in the replenishing space is gravity-fed into the mould so as to completely fill same. The steam is then replaced by cold, compressed, air, whilst maintaining pressure. As soon as the temp. has dropped below solidifying temp. the resulting moulding is removed, with simultaneous release of pressure.

Title: Cement mortar roofing tiles - treated to convert free lime into calcium silicate
Inventor: OTTENHEYM JOHANNES HUBERTUS
IPC: C04B28/18
Filed: 1974-10-08
Abstract: Roofing tiles made of a cement mortar mixt. are improved in that they contain hydrated Ca silicate formed from the free lime and SiO2 in the mortar mixt. during or directly after setting. Conversion of the free lime into Ca silicate avoids the discoloration due to weathering normally associated with mortar tiles; the tiles have mechanical properties as good as or better than those of the untreated lime-contg. tiles, and better frost resistance than ceramic tiles. The conversion of the lime into Ca silicate can be effected by treating the tiles (before or after setting) with steam at >100 degrees C (pref. 100-250 degrees C) at elevated pressure (pref. 14-18 bar) in an autoclave. The mortar mixt. pref. contains s small excess of fine sand, esp. quartz. sand.

Title: Mixing valve for coupled heating installation circuits - has two channels for inlet and outlet arranged at right angles to one another
Inventor: HAGEMANN FRANZ-JOSEF
IPC: F24D3/10
Filed: 1974-12-27
Abstract: The two channels (15, 16) positioned normal to one another are for the low temperature water while a third channel conveys the hot water and is couplable to the former channels by a controllable valve opening (19). The valve is therefore in the form of a T-piece containing a wall (18) with a valve seat (19) against which a valve body can be moved via a rod (21). The dia. of the valve seat is however relatively small in relation to the dimensions of the cold water channels (15, 16) so that even in the completely open valve position never too much hot water can flow into the low temperature branch. A throttle (23) is incorporated in the low temperature outlet of the valve chamber.
