Abstract: A method and apparatus for screening unwanted calls by processing coded information received through a telephone line during the non-active intervals of a ringing period. Once the ringing loop has been established, a calling party "dials" a pre-established code, which may comprise one or more characters, during one or more of the non-active intervals of the ringing period. If the code is correct, the called party is alerted. The indication furnished to the called party may be an acoustic signal, a flashing light, an alphanumeric display, or any other suitable indication means. The apparatus, during the ringing period and after such coded information has been received thereby, decodes and compares the codes with pre-established codes stored in a memory device and, if it finds coincidence between the received code and one of the memorized pre-established codes, it will validate the code.

Abstract: Disclosed is a method of producing granulated products from a suspension, which comprises in general the steps of spraying the suspension in a suspension spraying zone, introducing a heat-carrier in the form of a spiral flow to a zone disposed beneath the sprying zone, drying the suspension by the heat-carrier concurrently and countercurrently therewith and separating simultaneously fine fractions of the dried material by means of the same flow of the heat-carrier, with drawing a spent portion of the same, treating thermally the granules produced by drying countercurrently with the aforesaid heat-carrier upon their moving downward in a spiral to a temperature sufficient to ensure the desired product properties, withdrawing processed granules from the thermal treatment zone.

Abstract: The invention provides a method of producing discharge lamp arc tubes of ceramic material complete with metal cermet end closure members using initially incompletely fired sintered components and a sealing composition selected from silica, alumina and magnesia in proportions such that the composition falls within the accompanying ternary phase diagram BCDEFXYZPQ. The sealing compositions may also contain up to 5% by weight of nucleating agents such as phosphorous pentoxide, rare earth oxides, titania, zirconia or chromia. The inclusion of up to 5% by weight of boric oxide improves the flow characteristics and up to 10% by weight of Y.sub.2 O.sub.3, Yb.sub.2 O.sub.3, La.sub.2 O.sub.3, Dy.sub.2 O.sub.3, Eu.sub.2 O.sub.3, HfO.sub.2 improves the thermal and mechanical properties of the seals. The invention eliminates the need to make a first end seal by separate sintering and sealing operations.

Abstract: A laser nephelometric system measures the concentration of various substances in a solution particularly in blood or serum. The system receives a number of data elements each indicative of the intensity of light scattered from the solution at its sampling time. These data elements are processed in accordance with a statistical analysis. Based upon the fact that the relative variation of the scattered light intensity increases as the scattered light decreases, a first screening of data elements is performed so that the band of selection for data elements accords with the above fact. Further a second screening of data elements is performed in order to reduce the effect of the unnecessary light resulting from the other reflecting objects, such as dust, air bubbles and other substances. The average of the screened data elements provides an accurate value of the intensity of scattered light due to the substances to be measured, i.e. measurand.

Abstract: A collator includes a series of twenty bins arranged in parallel with each other, a copy feeding member for feeding copies supplied from a copying machine along inlets of the successive bins, first and second deflecting devices arranged at the uppermost two bins for delivering the copies into the uppermost two bins and a distributor movable between the third bin and the twentieth bin for delivering the copies into the bins. The collator can treat the copies in a job separation mode in which all copies of each documents are delivered into respective bins in succession, while the distributor is advanced bin by bin in response to a distributor advance signal produced by a variable timer which is actuated upon detection of the rear edge of the last copy of an Nth original by an entrance switch to set a time period represented by b+(N-1).times.a/V.sub.1, wherein a is a pitch between successive bins, b is a distance from the entrance switch to the first bin and V.sub.1 is a copy feed speed in the collator.

Abstract: A miniature portable physiological parameter measuring system with interchangeable sensors. In a preferred embodiment, the system is incorporated into a wrist-worn device having the general configuration of a wristwatch. The device contains, in the upper right-hand quadrant, an outcropping on which a pulse sensor is located. In the lower left-hand quadrant of the device, when worn of the left hand, diagonally opposite from the sensor described above, there is positioned a tiny plug. When the plug is removed, an open area is displayed which allows for the introduction of a connector in the wrist device. On introduction of the connector into the side of the device, the permanent sensor housed within the wrist device is disconnected and the remote sensor commences inputting a signal into the wrist device.

Abstract: A photosensitive member is formed by applying on an electrically conductive substrate, a first photoconductive layer sensitive to a visible light, an insulating charge retentive layer, and a second photoconductive layer sensitive to ultraviolet light, successively in this order. At first the photosensitive member is uniformly charged to a negative polarity, while the photosensitive member is uniformly exposed to the visible light. Then an image of a document to be copied is projected while the photosensitive member is charged to a positive polarity. After that the photosensitive layer is uniformly exposed to the visible light and finally the photosensitive member is uniformly exposed to the ultraviolet light. In this manner, an electrostatic charge image having high contrast and resolution is formed in the photosensitive member by means of charges which are stably trapped across the charge retentive layer.

Abstract: The apparatus comprises a constant level flow receptacle and an immersion type freeness tester having two chambers, namely a filtration chamber provided with a bottom screen portion, and a measurement chamber. A sensing element is placed inside the measurement chamber for determining the level of the liquid passed through the bottom screen portion, and connected to a circuit for measuring this level and for recording the freeness according to this level. The dimensions of the filtration chamber and those of the measurement chamber are so selected that, during the immersion of the freeness tester into the pulp, water is supplied into the filtration chamber at a constant pressure differential between the level of the upper edge of the filtration chamber and the level of the edge of the flow receptacle.

Abstract: A method of and an apparatus for testing the internal pressure of a sealed container carried on a conveyor belt by striking the container with an electromagnetic pulse thereby causing its wall to vibrate, and to check the internal pressure of the sealed container based upon the frequency of the vibratory sound produced by the sealed container. The vibratory sound is converted to an electrical signal by an electroacoustic transducer and is returned to a container striking device in a feedback path thereby to strike repetitively the sealed container with the same frequency of the vibratory sound. The repetitive striking produces continuously without damping a vibratory sound at a frequency commensurate with the natural frequency of vibration of the container. The testing of the internal pressure of the sealed container can be carried out in a stable manner with increased accuracy. A reject system is responsive to the vibratory frequency to permit passage of or to remove the container from the conveyor belt.
