Patent CH-652816-A5 (CH)
Title: Recirculating burner
Inventor: ROHS ULRICH
IPC: F23C9/00
Filed: 1981-02-09
Abstract: The recirculating burner has, arranged at a distance in front of the mixing pipe (11) and flush with it, an incoming-air opening (8) and a fuel nozzle (9) which is eccentric in relation to the mixing pipe. As a result of the injector effect of the combustion air, hot combustion gas is guided back as recirculating gas into the antechamber (17) of the mixing pipe. The closure of the combustion chamber (5) is formed by a deflection wall (6) which is arranged essentially perpendicularly to the axis of and at a distance behind the mixing pipe (11) which is held in an intermediate wall (12). This deflection wall has at least one combustion chamber outlet opening (14) which opens into the furnace space (4) of the boiler. Situated in the intermediate wall (12) next to the mixing pipe is at least one recirculating opening (13) for the combustion gas, towards which the fuel nozzle (9) is directed. The fuel is injected exclusively into the recirculating gas. This recirculating burner provides, in comparison with known burners, at the same pressure drop of the incoming air, a greater temporal quantity of recirculating gas so that a better starting behaviour, a more balanced fuel preparation and increased reliability against oscillations are achieved. <IMAGE>

Patent CH-663253-A5 (CH)
Title: Exhaust particle filter for internal combustion engines
Inventor: JENNY ERNST DR
IPC: F01N13/04
Filed: 1984-04-11
Abstract: The exhaust particle filter (7) for internal combustion engines (1) is divided into two ducts (7a, 7b) arranged in parallel. A control flap (10), which can be controlled as a function of the engine load, channels the exhaust gases (5) from the engine to one or both ducts (7a, 7b). Complete exhaust particle filtering is thus guaranteed during the entire period of operation. The controlled admission to the ducts (7a, 7b) permits complete burning of the exhaust particles trapped there. In the case of forced induction with a gas-dynamic charger, the particle-free exhaust gases (9) ahead of the pressure-wave machine (3) have a high mixing temperature, thereby guaranteeing a high boost rate. <IMAGE>

Title: Cardboard box for confectionery - sidewalls are formed from spaced walls formed from single flaps
IPC: B65D5/66
Filed: 1973-07-18
Abstract: The bos is made from cardboard or other suitable material and is cut out of a single sheet. This sheet is cut, crimped and folded in such a way that the edges can be folded over twice. This forms an inner wall within the box. The size of this inner wall is such as to leave just enough space for the object to be packed, without leaving much play.

Title: Multi-tubular boiler for producing superheated water - with longitudinal and transverse collectors connected by water tubes joined together
IPC: F24H1/40
Filed: 1974-08-07
Abstract: Multi tubular boiler for producing superheated water incorporates a combustion chamber which contains four longitudinal collectors connected by transverse collectors and a convention bundle of vertical water tubes situated in its extension. The collectors are joined to one another by water tubes which fix the boundaries of the combustion chamber. These tubes are joined together over all the surfaces of the chamber except that near the convection bundle, which constitutes an outlet for combustion gases and where one tube in two is offset towards the bundle. The vertical water tubes connect the transverse collectors giving circulation to and from the bundle. The water circuits is calculated for forced circulation by pumps, the collectors distribute the water flows rationally to absorb convected or radiated heat without risk of vaporisation and the tubes between collectors are short, giving intensive mixing of water and equalising temps. and pressures.

Patent CH-696684-A5 (CH)
Inventor: TOGNOLINI MAURIZIO
IPC: B23H7/04
Filed: 2003-05-22
Abstract: The electrical discharge machining device comprises a first voltage/current source (U1) for discharge initiation connected to the tool electrode (F) and a workpiece electrode (P) forming the poles of a machining gap (G) and a second voltage/current source (U2) that can be disconnected by way of two switches (SW1, SW2). Capacitive elements (C1, C5) are mounted in series in the lines (10, 11) connecting the first source to the poles of the machining gap (G). In addition, these poles can be connected by a self-induction coil (Lm) mounted in series with an adjustable DC source (Sm). Thanks to these features, the energy of the eroding discharges can be significantly reduced in order to obtain a superfine surface finishing process of high quality, while at the same time precisely controlling the mean voltage across the terminals of the machining gap.
