Title: Outdoor unit air conditioner with heat exchanger - has interconnected indoor units with compressors and heat exchangers preventing pressure imbalances
IPC: F24F1/00
Filed: 1976-06-10
Abstract: Air conditioner comprises at least one outdoor unit (8) including an outdoor heat exchanger (9) with several coolant pipes (13) which act as condensers during cooling. There are a number of indoor units (1) equal to the number of condensers in the outdoor heat exchanger.

Title: Producing grooved socket on tube in crystal-contg. thermoplastic - by hot upsetting followed by upsetting whilst equally hot socket forming (AT 15.8.82)
IPC: B29C57/02
Filed: 1981-06-29
Abstract: The tube end is heated to forming temp., then has its wall thickness increased by applying axial pressure whilst the end is placed in the annular gap in a heated mandrel-and-bush unit, after which the grooved socket is produced by axially moving the end into a forming unit, followed by cooling. The preheating and initial upsetting temp. is within a narrow range (around 5 deg.C) just below the crystal fusion temp. upsetting proceeding from the extreme end of the tube. The forming unit is at the same temp., the axial movement therein producing a further upsetting action to equalise loss of wall thickness due to widening as the socket is formed. Used for producing socket with internal groove at end of tube in crystalline or partly crystalline thermoplastic material. Existing methods used for amorphous thermoplastics such as PVC which have a gradual softening range are unsuitable as they produce irregular swellings in the crystalline material. In this process the second upsetting action eliminates the weakening which occurs during socket forming on a previously upset e.g. polythene tube end when using a method disclosed elsewhere, (US3899565).

IPC: C02F3/28
Filed: 1982-02-26
Abstract: The installation is intended for producing biological gas (methane) by fermentation of e.g. liquid stable manure. It comprises a number of fermentation tanks, a line to supply manure from a pit below the stable floor individually to successive tanks, a line to discharge worked-out manure individually from successive tanks into a collecting pit and a line connecting the tops of all tanks (and the preheating tank) to a (weighted) gas collecting bag.
