A high-flow concrete additive comprises a polymer of 10-100 wt% of an N-vinylacetamide, 0-50 wt% of a compound CH2=CR3X1R4SO3X2 wherein R3 is hydrogen or methyl, R4 is alkylene of 1 to 4 carbon atoms, X1 is CONH or COO, and X2 is hydrogen, an alkali metal, ammonium salt or organic ammonium salt, and 0-40 wt% of a compound CH2=CR5X3 wherein R5 is hydrogen or methyl and X3 is CN, COOR6, CONH2, CONHR...

A method for processing chemical cleaning solvent waste that combines evaporation, purification, and absorption. The method is mobile and thus allows the processing to be done at the site of the cleaning where the entire processing can be completed. Evaporation produces a concentrated solvent and vapor and gas. The concentrated solvent is absorbed to produce a dry residue for long term storage or ...

An actuator for a spray valve is provided which includes an actuator head and spray producing body positioned within the head. The actuator head includes a mechanism for connecting the head to a spray valve and transfer channel for receiving a pressurized fluid from the spray valve. The transfer channel is formed with a terminal area surrounding an outlet orifice of the channel. The spray producin...

The deodorant applicator comprises a container (4) enclosing the product to be dispensed having an axis of symmetry (X). An applicator (12) in communication with the container has an external applicator surface (16) which is covered by a cap (24). The cap has two orifices (36,38) which cause an air circulation in its internal volume. These orifices are located at different heights along the axis o...

A vibrating gyroscope having a vibratable body (3) in the form of a triangular prism, piezoelectric elements (5a, 5b, 5c) formed on side surfaces of the vibrating body and having the same vibration characteristics and a detection circuit (53) having two input terminals connected to two of the piezoelectric elements to detect the difference between the outputs from the two piezoelectric elements, t...

A snowboard binding with angular adjustment having a disk (3) rigidly connected to a snowboard, and a supporting base (5) for a shoe. A pawl (7) is associated with the base and selectively interacts, in contrast with a spring, with holes (12) formed on the disk. The pawl can be activated directly by the user and give a high degree of safety to the binding, keeping the selected angular position fix...

The HCN concentration of HCN containing synthesis gas streams is reduced by treatment with a Group IVA metal oxide and optionally containing a Group IIB, Group VA, or Group VIA metal or metals, at reaction conditions preferably suppressing Fischer-Tropsch activity.

A safety valve (4) enables the draining conduit to be pressurised forwards. The other side of the draining conduit is plugged with a pipe-plugging balloon so that the conduit can be pressurised with compressed air, causing its pores to open to the ground, so that it can against drain the area with open pores.

An outboard motor is provided with an engine holder, an engine mounted to an upper portion of the engine holder, a drive shaft housing mounted to a lower portion of the engine holder and an exhaust structure connecting an exhaust inlet opening formed to an upper surface of the engine holder to an exhaust outlet opening formed to a lower surface of the engine holder, in an installed state. The exha...
