Title: Block copolymer dispersion stabilising agent - with hydrophilic and hydrophobic blocks for aq. polymerisation
IPC: C08F/
Filed: 1977-03-18
Granted: 1985-05-31
Abstract: Polymerisation of an ethylenically un-satd. monomer (I) in water is effected in the presence of a catalyst and a block copolymer dispersion stabilising agent (DSA). This consists of is not 2 blocks, chemicall joined, with one block being hydrophilic, one hydrophobic and compatible with a polymerisable ethylenically un-satd. monomer. The hydrophobic block contains many gps. (II) with a chemical reactive functionality. The hydrophilic block constitutes 50-97 wt.%, the hydrophobic block 3-50 wt.% of the DSA. Procedure avoids problems of temp. control which exist with bulk polymerisation. No organic solvents are present to react with the monomer, cause agglomeration of the finished product or cause air contamination problems. The DSA being non-ionic does not cause colour problems with the polymers obtd., which are used to coat and impregnate a large number of substrates.
Patent IT-1102642-B (IT)
IPC: G10L15/10
Filed: 1978-05-11
Granted: 1985-10-07
Abstract: An apparatus and method wherein speech or other signals are sampled during a time slice of approximately 1/30 second and spectrum analysis is performed on the samples, producing measures of amplitude in several frequency bands with each frequency band being characterized by a binary digit indicating the presence or absence of significant amplitude. The binary digits are collectively referred to as a sonogram. Sonograms for several time slices are then concatenated, randomized and decoded using an n-tuple technique to produce a pattern corresponding to the current speech signal. This pattern is learned by superimposing it on an existing vocabulary entry and is subsequently recognized if it is sufficiently similar to one vocabulary entry and different from all others.

Title: Manually operated electric switch - comprises fixed contact member movable contact member and liquid element force transmitter
IPC: H01H/
Filed: 1974-12-03
Granted: 1978-05-10
Abstract: Manually operable electrical switch comprises switch housing, a fixed-position contact member, a movable position contact member normally urged by spring force into a closed position of touching engagement with the fixed contact member, an operating member responsive to slight external pressure to become positionally displaced thereby at an effective rate. Force transmitting means includes a liquid element as its operative medium in a normal state of equilibrium in the housing intermediate the operating member and the movable position contact member and in contact with the members. The force transmitting means is responsive to displacement of the operating member to transmit to the movable contact member an operating force of sufficient magnitude to move the movable contact member from its closed position of touching engagement with the fixed contact member. The force transmitting means is so constructed and its liquid element is of such viscosity that the spring force on the movable contact member acting through a time period related to the viscosity is sufficient to move the movable contact member back into engagement with the fixed contact member.

Title: Oxygen and hydrogen generating cell
Inventor: TOFFOLETTO LUCIANO
Filed: 1985-04-01
Granted: 1989-12-20
Abstract: The system generates a digital pixel image in a framestore memory (20) by expanding run-length encoded data stored in a command memory (22). Each pixel has a variable characteristic such as its colour, or its depth in a 3-D image. The value of the characteristic for each written pixel is determined from the run-length encoded characteristic. The value of the characteristic for each pixel in the run is determined from a reference parameter which determines the initial value of the characteristic, and a difference parameter which represents the change in the value along the length of the run. The coordinates of the pixel runs may be determined from the coordinates of a preceding run. The initial location and run length for each run are determined relative to the preceding run by delta parameters associated with the current run. The system generates linear colour blends and automatically depth-clips images being written into the framestore (20).

IPC: C04B28/24

Abstract: Disclosed is the solidification and chemical fixation of liquid wastes using biogenetic primarily amorphous silica to the waste in the presence of a strong alkali in the waste which converts the biogenetic silica into a soluble silicate, and in the presence of a polyvalent metal ion in the waste which reacts with the soluble silicate to provide a cementitious product of the waste. In the event there is insufficient strong alkali present in the waste to convert the biogenetic amorphous silica to a soluble silicate, and insufficient polyvalent metal ion in the waste to harden and form a cementitious product, amounts of these components as necessary can be added along with the biogenetic silica to the waste. The resulting cementitious and chemically fixed waste can be left in place, for example to provide a land farm, or can be removed and broken up and used as a cover for land fills, various land applications, and farms, as well as other applications.

Abstract: A packet switch receives data and processes it for assembly into packages. A bus allows communication between each of the data processing units of the switch and one or more storage units for storing the data packets. Arbitration for deciding which of the processing units will be granted access to the bus is performed by a system which selectively and alterably designates any of at least two different levels of priority of access to the bus for each of the processing units, and the relative percentages of time of access for the different priorty levels. The system assures greater access to the bus by those of the processing units having the higher level of priority. If communication is provided by two buses, the requests for access are alternated between them. The arbitration system provides selective access to the bus in any of a plurality of bus cycles including a read cycle, a write cycle and a read/modify/write cycle, and grants a request for access from a higher priority processing unit within one bus cycle.

IPC: F25B/
Filed: 1975-08-28
Abstract: Between a compressor (20) and a condenser (11) of the refrigeration installation, the refrigerant vapour flows through a heat recovery heat exchanger (25). The refrigerant vapour delivered by the compressor (20) is mixed with a concentrated absorption medium solution which is supplied e.g. by an injection device (39) and which absorbs a part of the compressed refrigerant vapour, as a result of which the temperature of the mixture flowing through the heat exchanger (25) is increased. After the heat exchanger (25), the solution diluted with refrigerant is separated from the remaining refrigerant vapour in a separator (30). In a concentrating device (35), the solution is subjected to the compressor inlet pressure in order to boil refrigerant off from the solution. The heat necessary for this is extracted from the remaining refrigerant vapour which at least partially condenses in the process. The solution, concentrated again, is supplied to the injection device (39) again. A part of the waste heat of the installation is thus delivered at a higher useful temperature level without the compressor having to be operated in an uneconomical compression range which is detrimental to the refrigerant. <IMAGE>
