Patent MX-9605701-A (MX)
Title: Disinfectants and sanitizers with reduced eye irritation potential.
Inventor: HALL LARRY K
IPC: C11D1/62
Filed: 1995-05-22
Abstract: It has been found that certain combinations of substituted imidazoline-based amphoterics and quaternary ammonium compounds show markedly reduced irritation profile in addition to providing excellent cleaning detergency. Moreover, it has further been found that certain substituted imidazoline amphoteric surfactants in combination with didecyl dimethyl ammonium chloride (DIDAC) show unexpected synergistic irritation reduction compared to that observed when the quaternary is an ADBAC type. This allows the formulation of disinfectants and sanitizers with the favored antimicrobial agent while at the same time affording the optimum reduction in irritation potential.

Inventor: WETZEL UWE
Filed: 1997-01-13
Abstract: The present invention describe a control device to control and to check two valves for fluid, wherein each valve comprises an impelling means, which is adapted to actuate an associated control signal, and a movable valve means which is derived towards a first position, wherein flow through valve is prevented and which can be carried by displacement means to a second position, wherein fluid is capable to circulate through valve, a first switch which is actuatable by first valve displaceable means, a second switch which is actuatable by second valve displaceable means, wherein each switch can be displaced to a second position, when associated valve displaceable means takes its second position. According to the invention, both switches (20, 21) are adapted to directly influence control signal paths in both commutation positions, and are connected in a way that prevents first control signal (S1) application to first valve on its first position when first control signal (S1) application is carried out, after a predetermined period of time has been passed from second valve actuation, and to prevent second control signal (S1) application to second valve when it is on its first position, if second control signal (S2) application is carried out after a predetermined period of time has passed, subsequent to first valve actuation. Both switches (21, 21) are connected in so as to allow control signal to being applied to a respective impelling mounting when both switches simultaneously occupy their first position, or simultaneously occupy their second position.

Title: Method and apparatus for recording and playing back continuous-play video signals together with stop-motion video and audio signals
Inventor: GOLDING SCOTT MITCHELL
IPC: H04N5/92
Filed: 1987-12-30
Abstract: An improved method and apparatus for recording and playing back a video signal on a video disc, such that selected video frames can be played back in a stop-motion fashion, with accompanying audio. Each stop-motion video frame is recorded on a single recording track on the disc, and an associated digitized stop-motion audio signal is combined with a continuous-play video signal and recorded on a plurality of preceding tracks. During playback, the tracks recording the continuous-play video signal are first scanned, to recover and display the continuous-play video frames, and to recover and enter into a memory the digitized stop-motion audio signal. The track recording the corresponding stop-motion video signal is then scanned, in a repeated fashion, to provide a stop-motion display of the video frame, while the stop-motion audio signal is extracted from the memory and converted back to its original analog format, for playback along with the stop-motion video frame.

Patent NL-6411272-A (NL)
IPC: G10L21/00
Filed: 1964-09-28
Abstract: A continuous reaction is effected in a gas stream by an electric discharge at a point in the stream where the flow has been made supersonic and the pressure and temperature lowered by a substantially adiabatic expansion.  Various forms of apparatus for carrying out such a process are described.  The apparatus may be used for the production of ozone which is used to convert ethylene and tetramethyl-ethylene fed into the apparatus into the corresponding ozonides. On leaving the apparatus the ozonides are converted in the presence of water into formaldehyde and acetone respectively.ALSO:A continuous reaction is effected in a gas stream by an electric discharge at a point in the stream where the flow has been made supersonic and the pressure and temperature lowered by a substantially adiabatic expansion.  One form of apparatus, Fig. 1, comprises a supersonic nozzle 1, a pressure reducing chamber 17 for starting the action of the nozzle and a recompression chamber 13. Gas from an inlet pipe 6 passes along a cylindrical chamber 5 to a convergent part 2 of the nozzle 1 and then expands in a divergent part 4.  A hollow electrode 8 supported by insulators 9 and 10 in the chamber 5 produces a discharge at the outlet 7 of the nozzle 1.  The recompression chamber 13 comprises a convergent part 14, a cylindrical part 15 and a divergent part 16. This apparatus may be used for the production of acetylene and hydrogen from methane gas, or for the cracking of other hydrocarbons. An alternative form of apparatus is described in which the electrode 8 is extended to the part 16 of the chamber 13 and is closed at the end, but is provided with side vents for the injection of methane into the part 15 of the chamber 13.  Two discharges are set up, the first at the end of the nozzle 1 for producing ozone, and the second in the chamber 13 for partially oxidizing the methane. <PICT:0987902/C4-C5/1>

Patent NL-7710814-A (NL)
Title: Felted yarn with varying surface properties - prepd. from separate strands with differing surface properties, allowing variation and contrast to be selected
IPC: D02G3/28
Filed: 1977-10-03
Abstract: A yarn consists of felted fibres, brought together so that the surface of the yarn displays variations in properties (pref. in colour, but also texture in glaze) along its length. The yarn is fabricated by subjecting sparate strands of differing surface properties to the felting treatment. Depending on the extent of the mixing prior to the felting, the variations can be strongly contrasting or distributed. The surface properties along the length of the yarn may be varied by using one core strand and felting several strands to it at different posns. along the length. The method enables a wider variety of surface colour and texture to be achieved than is currently possible.
