Title: Domestic water softening appts. - with squeeze bottle containing ion exchanger resin filled cartridge
IPC: B01J47/024
Filed: 1977-06-13
Abstract: A water softening device for domestic purposes (for electric steam irons or for cosmetic purposes) contains the tap water to be treated in a bottle made of elastic material (PVC). The ion exchanger resin is contained in a cylindrical vessel, attached to the screw top and is accessible through gaps in the vessel cap. Soft water can be ejected from anozzle in the screw top by squeezing the bottle.

Title: Melting lost wax patterns out of casting crucibles - with rapid cooling of wax to avoid fumes, esp. in mfg. dental prostheses
IPC: B22C9/04
Filed: 1977-11-23
Abstract: The appts. consists of a hollow, C-shaped frame made of sheet metal. The upper arm of the frame contains a grid on which the crucible is placed so the wax can run out of its spout; and in the upper arm is a fan and an electric heater generating a current of hot air which heats the crucible and melts the wax. The molten wax flows downwards into a metal dish resting on the lower arm of the frame and not exposed to the current of hot air; the metal dish may also be cooled. The underside of the upper arm of the frame pref. has a gap below the grid so the molten wax can flow downwards into the dish in which rapid cooling occurs. Used for mfg. lost wax castings, esp. in a dental laboratory. The wax is rapidly cooled so no noxious fumes are evolved; this means that a fume extn. duct is not required in the laboratory.

Title: Method and assembly controlling burner stoichiometry - has oxidant adjusted to obtain ratio near stoichiometric in control burner, then mixture is supplied to main burners
Inventor: NOIR DOMINIQUE
IPC: F23N1/10
Filed: 1977-12-14
Abstract: The ratio of fuel to oxidant in a gas mixture to main burners in a furnace, where the fuel is of variable composition, may be controlled to a predetermined level. This is accomplished by burning a portion of the fuel in a control burner, adjusting the oxidant to obtain a ratio of fuel to oxidant near the stoichiometric ratio in the control burner and supplying the main burners with independent preset multiples of the fuel and oxidant flow in the control burner such that the predetermined ratio of fuel to oxidant is achieved. The stoichiometric ratio is determined by automatic searching for the peak value of a burning or burned fuel property which has a maximum value as a function of the fuel/oxidant ratio at or near the stoichiometric ratio.

Inventor: HEGLER WILHELM
IPC: B29C48/30
Filed: 1978-07-22
Abstract: An apparatus for the manufacture of transversely contoured tubing from thermoplastic material. The tube emerges in the plastic state from an extrusion nozzle and is guided into a mold composed of a plurality of mold sections in series, with inner side working surfaces forming the transverse contours. Each of the mold sections is composed of two mold halves which are arrayed along a straight molding run in two confronting rows and which are circulated. In the circulation, the first two mold halves are moved apart and out of the molding run at the end of the molding run and are guided to a return run on which they are separately returned to the beginning of the molding run where they are rejoined to the preceding mold half. The mold halves are guided on the return run in a continuous, accelerated and then decelerated movement by a transfer mechanism which couples and uncouples from the mold halves as actuated by pneumatic cylinders under the control of limit switches.

Inventor: ZEMANEK JOSEF DIPL ING
IPC: H04Q11/04
Filed: 1978-09-28
Abstract: A method for the synchronizing of sending and receiving devices in a PCM telecommunication network employs a counter which is reset by each bit representative of a binary 1 in the received message and which produces a signal for enabling the synchronizing device when it reaches its end count. The counter is incremented by clock pulses produced at the receiving station, and the radix of the counter is selected to exceed the number of bits representative of binary "0"s which can appear consecutively within the message, and the time required for the counter to reach its end count is almost as long as the pause between successive message words.
