Title: Axial trajectory sensor having gating means controlled by pulse duration measuring for electronic particle study apparatus and method
IPC: G01N15/12
Filed: 1972-04-07
Abstract: A sensor for use with apparatus operating in accordance with the principles of the Coulter electronic particle studying device for differentiating between signals from particles passing on axial or near axial trajectories through an aperture and particles passing off center. The particle pulse duration is measured at two or more fractions of the amplitude for each individual particle pulse. These pulse durations so measured are converted into voltages which represent the respective durations of the several fractional amplitudes and are compared with certain reference voltages. The reference voltage for one fractional amplitude is derived from a memory circuit which remembers the duration at that same fractional amplitude for the smallest of prior pulses processed by the sensor. Using this information, a reference voltage is established for that one fractional amplitude as the maximum permissible level below which the duration-representing voltage is acceptable and above which the duration-representing voltage is not acceptable. This same reference voltage derived from the memory circuit is used to establish maximum and minimum levels for the other fractional amplitude duration-representing voltages. In addition to the one duration-representing voltage falling below its reference level, the duration-representing voltages of all other fractional amplitudes must fall between the maximum and minimum reference voltages, respectively, which have been established for them in order to operate gating means to pass the particle pulse. All other pulses will be disregarded. On such account, pulses must have the proper shape and duration to be passed by the sensor.

Title: Apparatus for producing de-boned meat products
IPC: A22C25/16
Filed: 1973-05-02
Abstract: Material obtained from animals, poultry, or fish and containing edible flesh along with normally inedible relatively hard or tough components, such as bone, gristle, tendons, etc., is fed in ground condition into one end of a perforated conduit that has a conveyor srew therein which progressively decreases in conveying capacity from the feed end of the conduit to an imperforate discharge end thereof. Such inedible components are compacted within the imperforate discharge end of the conduit by an extension of the conveyor screw prior to discharge following build-up and conveyance along the interior surface of the perforate portion of the conduit as a filter mat through which edible flesh is forced toward and through the perforations of the conduit to provide a substantially bone-free edible product. The discharge passage surrounding the exeension of the conveyor screw can be varied in size, preferably by a tapered ring that is movable back and forth axially of the conveyor screw extension, and preferably the spacing between conveyor screw and conduit is variable. The forward faces of the conveyor screw flights are preferaby concave to provide a forwardly projecting circumferential overhang that tends to keep particles of bone near the axis of the screw, and the conduit wall thickness is unusually thick so as to withstand high pressures. Unusually high production rates can be obtained by feeding finely ground material into the conduit by means of a hgh pressure pump. The discharged and normally inedible components can be slurried in a digestant liquid and the digested material recovered as a food product by the application of centrifugal force. In instances where some minute particles of bone are discharged with the fleshy components, they can be homogenized by subjecting such flesh components to an attrition operation.

Patent ES-432281-A1 (ES)
Title: Extracorporeal blood circuit
IPC: A61M1/30
Filed: 1974-11-26
Abstract: An extracorporeal blood circuit including a haemodialyser and a pump for pumping blood to and from the haemodialyser, and a single needle for the passage of the blood to and from the body. The single needle is connected to the stem of a Y-shaped coupling, the first branch of which is connected to an inlet pipeline for the pump, an intermediate pipeline connecting the pump to the inlet of the haemodialyser, the outlet of which is connected to the second branch of the Y, a bubble trap being included in the outlet pipeline. A device is provided which seals the inlet and outlet pipelines intermittently and this is driven in a cyclic manner at a predetermined frequency. The haemodialyser and/or the pump and/or the intermediate or outlet pipeline has a variable internal volume which is sensitive to the variations in the differential pressure instantaneously existing between its interior and atmosphere. This may be effected by making some of these elements resilient, so that they can expand when the pressure increases. By this means it is unnecessary to provide pressure detectors which control the alternate occlusion of the pipelines. This substantially reduces the cost of manufacture and running the blood circuit.

Patent ES-476417-A1 (ES)
Title: Method and apparatus for conditioning demineralized water
IPC: C02F1/20
Filed: 1978-12-28
Abstract: The invention relates to a simple, very economical apparatus for conditioning "aggressive" demineralized brackish water or sea water to remove CO2 and raise the pH to about 8. The invention is undemanding as to operator skill and attention and can be used economically with rather small quantities of water, such as a few thousand gallons a day. It requires no instruments or controls and utilizes inexpensive, generally available materials, principally limestone chips. The water is first sprayed at low pressure against a conical surface to cause it to film and release the bulk of the free CO2. The water is then fed upwardly through a bed of limestone chips with at least a two minute reaction time to convert the balance of the CO2 to calcium bicarbonate which is soluble and produces a pH of about 8.
Patent ES-481838-A1 (ES)
Title: Fluidized bed powder discharge and metering method and apparatus
IPC: B65B1/16
Filed: 1979-06-22
Abstract: A metering method and apparatus is provided for the controlled discharge of powder from a fluidized-bed blender to a material container, which gives accurate material weights while separating powder from fluidizing gas. In this method the material container is filled with a series of short duration discharges at a reduced powder flow rate. This method enables the apparatus to more precisely measure the weight of the container and maintain homogeneity of the blended material in both the bed and the container. The apparatus for carrying out this method includes a flexible pressure-tight sleeve connecting the fluidized bed to the container. When a ball valve located at the bottom of the fluidized bed opens to discharge powder, the sleeve retains the high pressure fluidizing gas inside the sleeve and the container. This causes the pressure to build at the outlet of the valve thus preventing the gas from rapidly exhausting and forcing powder through the outlet. The short duration discharges are terminated when a load cell, provided to electronically weigh the container, measures a predetermined material weight. To improve accuracy, the load cell measurement is monitored only during the relatively quiescent period between discharges, and the measured weight of the material in the container is continuously corrected to eliminate the effects of fluidizing gas pressure forces. Finally, an off-gas hose extending from the container lid exhausts the fluidizing gas at a controlled rate of flow and separates the gas from the powder.
Patent ES-481871-A1 (ES)
Title: Solar energy collection
IPC: F24S10/70
Filed: 1979-06-25
Abstract: The invention is a solar energy conversion apparatus in which several evacuated, glass tubular collectors are connected together in a liquid circulation system for controlled movement of a liquid between the interior of the collectors and a storage tank. Liquid circulation is controlled by sensors and switches therefor in regulating operation of valves and/or a pump. The conditions for circulating the liquid rely upon (1) sensing a need for energy at the storage tank, (2) sensing solar radiation availability, (3) sensing thermal conditions in the solar collector tubes to avoid high temperature and thermal shock, and sensing a need to withdraw hot liquid and add more. The system is operable in either of two modes herein disclosed: (a) the "continuous batch circulation" mode in which liquid is pumped to fill the tubes, in parallel, and low temperature sensed below a set point to stop pumping and resume pumping when the temperature in the tubes arrives at the preselected higher temperature, and (b) the "full continuous circulation" mode in which liquid is continuously pumped through the tube collectors, in parallel, continuously withdrawing liquid from the top of the tube while introducing liquid at the bottom of the tube in either mode, the hotter liquid being removed from the top of the tubes and relatively colder liquid introduced at the bottom of the tubes. The invention includes a full drainability of all the tubes of the system under control when conditions are sensed to call for draining the tubes such as, the end of the solar day, the storage tank temperature exceeds a certain value (enough energy is stored), or tube temperature is too high and, restarting of circulation of liquid to the tubes is abated until their temperature is within preselected operating range. The system will operate using water without additives without danger of freeze up and all collected energy is placed in storage at the end of a solar day period. The system includes a second circulation system through the storage tank to remove the heat in utilizing it, such as in a domestic hot water system. This second system removes water to be heated from the base of its hot water tank and pumps it through a heat exchanger in the solar heated liquid tank and back to the top of the hot water tank.
