Title: Methods for the production of heterofilaments
IPC: D01F8/04
Filed: 1963-07-31
Abstract: Composite or heterofilaments and heteroyarns are produced by separately metering into a spinneret assembly comprising a cover, housing and spinneret plate at least two synthetic polymers in a viscous liquid state, i.e. either viscous melts or viscous solutions. The polymers allowed to meet and form a liquid interface or interfaces and are forced, after forming the liquid interface or interfaces through a filtering medium contained within the spinneret assembly and are extruded through the orifices in the spinneret plate to form filaments which are subsequently drawn to orient them. The polymers may be metered into the assembly in a molten state and after forming the liquid interface or interfaces, and being forced through the filtering medium contained within the assembly may be extruded to form filaments which are solidified by a transverse blast of air. The liquid interface(s) formed by the polymers within the spinneret assembly and the orifices within the spinneret plate may be arranged to be parallel and in the same vertical plane and the volumetric flow rates of the polymers may be adjusted to produce heterofilaments (composite filaments) in which the polymers are in side-by-side relationship. The interfaces and some or all of the spinneret plate orifices may be otherwise disposed with respect to each other so that some or all of the filaments produced are homofilaments consisting wholly of each of the polymers. The polymers may be polyamides. At least one of the polymers may be polyhexamethylene adipamide. One of the polymers may be an interpolymer of polyhexamethylene adipamide and polyepsilon caprolactam, e.g. in the proportions 80 : 20. At least one of the polymers may contain a delustrant such as titanium dioxide or a coloured pigment. At least one of the polymers when in filamentary form may be an elastomer or a potential elastomer. At least one of the polymers in filamentary form may be potentially adhesive under conditions in which at least one other component in filamentary form is non-adhesive. One component in filamentary form may have a greater shrinkage capacity than the other polymer(s) in filamentary form. When one of the polymer components can be rendered adhesive by heating, the heterofilaments may be used to form non-woven fabrics, the filaments being bonded together at their cross-over points by heating them. The heterofilament may consist of a polyhexamethylene adipamide component and a polyepsilon caprolactam component, the latter being rendered adhesive by heating the filament to temperatures at which the other polymer is still non-adhesive.

Patent ES-357404-A1 (ES)
Title: Hydraulic control valve with void prevention means
IPC: F16K11/07
Filed: 1968-08-20
Abstract: A spool valve 18 controlling the supply and exhaust of pressure fluid to and from a double-acting jack 6 through two service passages A, B, is provided with means for preventing cavitation in the expanding end of the jack cylinder when the jack piston 8 is descending rapidly under the action of the load 9, in a " float " position of the valve as shown. In this position both service passages and the inlet 19 communicate with outlet 15. Return fluid to a service port B, which can pass from a return passage 26 through a restricted passage 43 to the drain port 15, builds up an increased pressure in the return passage. This passage communicates through a feedback passage 31 and check valve 32 with the other service port A. Thus when the pressure supplied to port A by a pump through inlet 19 falls, the supply is supplemented from the feedback passage 31. Branch passages 23, 24 adjacent the service ports are connected with the inlet 19 through a common check valve 25. The spool valve is of open-centre type and in a neutral position of the spool to the right of that shown, the inlet 19 communicates directly with an outlet 20 when the service ports are isolated. The flow then goes through a spring-loaded valve 36 containing the restricted passage 43. There is a " raise " position to the right of neutral, and a " power down" position between neutral and that shown. In the " power down" " position, service port A is supplied from passage 24 and service port B communicates with return passage 26. Where the jack is arranged to pull up the load, the connections to the jack being reversed, cavitation is especially likely and is likewise prevented. In another embodiment, two spool valves (18) are provided in a sectional valve body (105) for controlling separate jacks in parallel. In a modification, the restricted passage 43 is replaced by a passage (128) in the valve housing. In other modifications a check valve (163 or 63) is fitted either between the passage 26 and the restricted passage or bypassing the restricted passage, Figs. 4-6 (not shown).

Patent ES-370812-A1 (ES)
Title: Device for the detection of the flow of fluids
IPC: G01P13/00
Filed: 1969-08-25
Abstract: A fluid flow detector comprises a temperature variable resistor 3 of which a surface is in thermal communication when the fluid is flowing but is thermally insulated from it by a flexible heat-insulating diaphragm 11 when fluid does not flow. The resistor is heated by a constant electric current so that when the diaphragm is raised from the casting 5 due to pressure difference between inlet and outlet pipes 1, 2, fluid flows past the resistor and extracts heat therefrom whereby the resultant temperature change is detected to indicate the fluid is flowing. An aperture 15 in the diaphragm connects the outlet pipe with a chamber 16 in which a spring 12 is seated. The spring acts on an abutment 13 fast with the diaphragm to urge it to the casting 5 thereby blocking flow between inlet and outlet.

Title: Event monitoring transceiver
IPC: H04M3/36
Filed: 1975-01-23
Abstract: A data terminal utilizes a time division multiplexer to monitor traffic on 16 input lines and convert the information from parallel to serial form as a 16 word serial message, records the count data for each input line, and transmits accumulated count data over a phone line as a serial message of 16 sequential 16 bit words. The terminal has a Count Register and a Storage Register each of which is a 256 bit serial shift register. The Count Register is the active memory that stores the counts of the events as they occur while the Storage Register receives data from the Count Register periodically, and holds the data for transmission. The terminal operates in either cumulative or peak modes. In cumulative mode the count for each input line is transmitted when the terminal is interrogated. In peak mode the terminal stores and transmits for each line only the highest count which occurs during successive selected time intervals, such as an hour or half hour. In both modes data is transferred from the Count Register to a Comparator for comparison with data in the storage Register and the higher count is retained in the Storage Register. Incoming data continues to be received and the counts in the Count Register are incremented even during data transfer. One terminal input circuit may be utilized to count elapsed monitoring time in minutes. A traffic usage scanner pulse is provided to activate a usage scanner. Operation of the terminal is automatic, and data readout and subsequent clearing of the registers and counters is controlled by the remote interrogating unit.
