Abstract: In a radio concentrator system found by a central station (3) and remote stations (4), demand-assigned data channels are constantly monitored to detect when they are congested. When an emergency call is received from a subscriber terminal (6), a dial tone is sent to the terminal if the emergency call occurs simultaneously with the detection of a congestion. On hearing the dial tone, the subscriber dials an emergency destination address, which is received by a remote station and compared with a list of predetermined addresses and verified if it matches one of the predetermined addresses. The dialled information is sent from that station to the central station, where it is relayed to a switched network (1). An emergency channel is established to the network for routing the emergency call. This channel may be permanently provided and demand-­assigned in response to an emergency channel assignment request, or first selected by a remote station requesting an emergency call and access is granted by the central station if no collision occurs between competing emergency calls. Alternatively, no emergency channel is provided in the system and one of the data channels is cleared when an emergency call is detected simultaneously with the occurrence of a congestion. The cleared channel is used as an emergency channel to complete the emergency call.

Abstract: Methods and apparatus are disclosed for transferring data to and from a first bus, to which a first set of high performance devices, including at least one central processing unit ("CPU") is attached, and a second bus, to which a second set of relatively lower performance devices is attached. More particularly the invention accomplishes the aforesaid transfer function in a manner that facilitates communication between the first and second set of devices from the compartive­ly lower performance of the second set of devices. According to the preferred embodiment of the invention, a data transfer controller i.e., ("DTC") is disclosed that includes a set of direct memory access ("DMA") channels and an input/output controller comprising a set of address mapped I/O ports. Both the DMA channels and I/O ports may be used to transfer data between the high performance channel (hereinafter referred to as the "Local Bus") coupled to the CPU in a reduced instruction set computer (RISC) system and a typically lower performance, peripheral bus (herein­after referred to as a "Remote Bus"). The resulting DTC interface between the Local Bus and a Remote Bus permits a wide performance range of standard peripheral devices to be attached to the RISC system in a manner that does not limit system performance.

Abstract: Apparatus is provided for use in detecting the peak voltage applied to a radiation source operating at an unknown input voltage. The apparatus includes a set of radiation absorbing filters including a first filter which includes a first element that exhibits a known K-absorption edge and a second filter constructed of a second element so that the filters exhibit essentially the same radiation absorption characteristics below the K-absorption edge of the first filter. The filters are adapted to be positioned so as to be irradiated by the radiation source so that the radiation impinges upon a surface of each filter and is partially absorbed as it passes therethrough so as to exit therefrom as attenuated radiation. A detector, such as X-ray film or a pair of photodiodes, is positioned for receiving the attenuated radiation passed by the first and second filters and provides an output indication when the radiation passed by the filters is differently attenuated. This is indicative that the known K-absorption edge of the first filter has been exceeded, thereby providing an indication as to the magnitude of the voltage applied to the radiation source.

Abstract: A process for the removal of heavy metal ions and particularly cadmium and copper from phosphoric acid of a concentration in the range of 20% to 52% by wt P₂O₅ is described. The process consists in a treatment of phos­phoric acid with a reducing agent and a thio-organophos­phene reagent, the heavy metal ions being retained on a solid adsorbent. According to one embodiment the process is carried out during the production of wet-process phosphoric acid, the calcium sulfate co-produced being the adsorbent. According to another embodiment,a solution of phosphoric acid, obtained by mixing a filter acid phosphoric acid with a more concentrated phosphoric acid solution, is treated according to the process, using an adsorbent selected from the group consisting of calcium sulfate, active carbon and aluminum silicates. The thio-­organophosphene reagents are selected from tri-n-propyl­phosphene sulfide, diisobutyl dithiophosphene sulfide, tri-n-octylphosphene sulfide, dicyclohexyl phosphene sulfide, diisobutyl dithiophosphinate and dicylcohexyl dithiophosphinate.

Abstract: An algorithm converts true lines into a selection of coordinate points on an X and Y axis coordinate grid for representing integral coordinate points representative of the line. These coordinate points correspond to pixel locations for printing of an image on a print medium. The algorithm takes into account the true endpoints of the line to be represented and derives a variance value which accounts for the position of the true endpoints relative to the initial integral coordinate points selected. This variance value then is carried through the computational process for each coordinate point selection, so that the cumulative variance signal represents the offset of the initial line endpoint. The result is the representation by integral coordinate points which are aligned with the true line, and which represent collinear lines collinearly.
