Title: Improvements in and relating to display systems
IPC: H01H13/83
Filed: 1981-02-28
Abstract: A liquid crystal (LCD) display arrangement has separate LCD's 12 ("ENTER"), 14 ("CLEAR"), 16 (digits "0" to "9") and 18 (a frame for a digit display). These LCD's are arranged behind a screen and initially only the LCD 12 ("ENTER") is visible. Each of the LCD's 12, 14 and 16 incorporates a proximity switch; when the operator touches LCD 12 ("ENTER"), logic causes the LCD's 14, 16 and 18 to be rendered visible and the operator can then enter digit values into the system by touching LCD's 16. The digits touched are displayed within the frame 18. When the operator touches LCD 14 ("CLEAR"), the LCD's 14, 16 and 18 are switched off and become invisible. <IMAGE>

Patent GB-2082933-A (GB)
Title: High voltage semiconductor materials and structures and method for their preparation
IPC: C30B13/06
Filed: 1981-08-11
Abstract: This invention provides for mounding a single-crystal doped boule of silicon in a float zone apparatus. A vacuum or other ambient is established within the apparatus and an rf coil is passed along the boule's length. The rf power is such that the boule is melted to depth "d" which is less than the diameter of the boule. Dopant within the molten depth "d", diffuses to the surface of the melt and evaporates, thereby leaving upon resolidification a relatively high resistivity single crystal sheath along the length of the boule. Wafers cut from the boule can be used for making semiconductor devices with a high resistivity edge portion, thereby providing a device with a high breakdown voltage without the need for field rings, bevelling or coating. <IMAGE>

Title: Sodalite photo and/or cathode- chromium material, method of producing it and sensitive element of a variable light transmission device made of that material
IPC: G11C13/04
Filed: 1981-03-31
Abstract: A sodalite photo- and/or cathode- chromium material is a transparent monolith with a homogeneous polycrystalline structure having a density of more than 99% of the theoretical density of the sodalite of the corresponding chemical composition. The material is produced by hot moulding of the sodalite powder, obtained by any method, under conditions which would exclude intensive volatilazation of the alkaline halogenides and unwanted melting of the sodalite. The sensitive element of the thus produced material is shaped as a plate the thickness of which is chosen depending on the required sensibility of recording the radiation and the required contrast of the recorded image when the sensitive element is used in a translucent mode.

Title: Apparatus for mixing respiratory gas and a liquid
IPC: A61M16/18
Filed: 1982-03-16
Abstract: An apparatus is disclosed for admixing anesthetic with respiratory gas to be supplied to a patient, which comprises a mixing chamber having an inlet for receiving the liquid anesthesia and the respiratory gas, and an outlet for supplying the mixture. A feed line is provided in the inlet for the liquid anesthesia, with a heat exchanger for equalizing the inlet temperatures of the anesthesia and respiratory gas. Temperature sensors are provided in the inlet and the outlets with a circuit for determining the difference between the temperatures.

Title: Frequency-hopping radio communication system
Inventor: DENT PAUL WILKINSON
IPC: H04B7/26
Filed: 1983-01-21
Abstract: A frequency-hopping radio communication system in which a network of stations operate on the same sequence of frequencies, in synchronism, controlled by pseudo-random generators which are initially synchronised. Each station has means for modifying its p.r. sequence dependent only upon the instant in the main line sequence at which the modification is switched. In order to communicate, one station transmits, on the current main-line frequency sequence the address of the desired other station and then signals the sequence switch. At this instant both transmitting and receiving stations switch to a modified frequency sequence and are thus isolated from the remaining stations. At the end of the message a signal from the transmitting to the receiving station causes both stations to revert to the main line sequence.

Title: Speech-controlled phonetic typewriter or display device
Inventor: GRIGGS DAVID THURSTON
IPC: G10L15/22
Filed: 1983-08-23
Abstract: In a first tier of operation the audio input is fed to sound separator 12 and to plosive sensor 14, fricative transducer 18, nasal transducer 20 and vowel identification section 24. The speech sounds are thus sorted into four types while the separator 12 indicates the presence or absence of voicing. The identified speech sounds are passed by input synchronizer 32 to a transcriber processor 34 the output of which goes to the printer/display 36. In the first tier the identified sounds are broken down into syllabits whose spoken sequence is separated into possible words, the grouping of the syllabits being indicated. In the second tier a comparison is made with stored words narrowed down to essential phonemes. Thus all except the specific word spoken which contains each of the detected phonemes in the proper sequence can be eliminated from the possible words. The specific word is then printed or displayed in the conventional spelling held in the store. <IMAGE>

Title: Apparatus for preventing scale formation in water systems
Inventor: GAUGER RAYMOND G
IPC: F28F19/01
Filed: 1983-09-07
Abstract: The apparatus has a unitary member (10) with a web portion (14) extending diametrically within a fluid carrying conduit (12), with fin members (16, 18, 40, 42, 44, 46) extending from opposite surfaces thereof into proximate or abutting relation with the inner wall of the conduit. The fins are undulate in form to define fluid flow passageways providing a venturi effect with the fluid velocity fluctuating during traversal therethrough. Adjacent passageways fluctuate the velocity differently so that the composite effect at the exit end of all passageways is to promote turbulence in the fluid leaving the apparatus to prevent scale formation in the conduit. In a first embodiment (Figures 1-5) the configuration of the fins on opposite surfaces of the web portion are different to provide different rates of fluctuations of the velocity. In the other embodiments (Figure 6, and Figures 7-10 not shown) the fin configuration is generally identical on both sides of the web portion. <IMAGE>
