IPC: B31B19/90
Filed: 1969-03-26
Abstract: Sealable bags are formed from synthetic resin material by folding the film so that one side is longer than the other to produce a flap to the inner surface of which is applied a ribbon of pressure sensitive adhesive which is then dried before applying a strip of pressure adhering but removable tape of synthetic resinous material over the ribbon, cutting the film into lengths and sealing the film at the cuts to form the bags. The synthetic film (a) is fed from a roll to a folding plate (2) mounted on the machine frame (1), the plate (2) with the aid of rollers (4, 4a) producing the fold in the film.

Title: Furnace carbon black mfr - with continuous control of particle size by ir analysis of outlet gas
Inventor: ROTHBUEHR LOTHAR DR
IPC: C09C1/50
Filed: 1971-03-19
Abstract: The particle size of the product, as characterised by iodine adsorption, is maintained constant by continuous IR analysis of the gas at the outlet for CH4 and for C2H2, or CO content and consequent proportional adjustment of the flow rate of combustion gas and/or oil feed, or of the air supply. The flow of combustion gas and/or oil is adjusted inversely proportionally to the CH4 and/or C2H2 content and in inverse proportion to the CO content. The total hydrocarbon content may be measured by flame ionisation detectors and used to control the process. Finer control of the particle size of the carbon black is obtained than by known methods e.g., measurement of thermal conductivity of the effluent gas.

Title: Swimming bath air conditioning system - has heat exchangers in heat pump for air dryer switched out
Inventor: FRIEDRICH HANS GUENTER
IPC: F24F5/00
Filed: 1974-01-18
Abstract: An air conditioning system for a swimming bath, circulates the damp air around a circuit with fresh air entering on the discharge side and a heater on the return side, which includes a heat pump containing a condenser cooled down by water from the swimming pool. The heat pump also has a compressor, and the cooling medium is circulated between the compressor and the condenser through two finned heat exchangers in parallel, past which the circulating air flows, to heat it. These heat exchangers are each preceded by a valve so that one or both can be cut off when required, by e.g. a temperature sensing device. When both are cut off, the coolant travels via a by pass line, and check valves block off the ends of the exchangers remote from the valves.
