Title: Phonetic encoding system of Chinese characters
Inventor: LI JIN-KAI
IPC: B41J3/01
Filed: 1984-04-12
Abstract: 26 Latin letters are used for representing 21 consonants and 37 vowels in Chinese, to spell a character with two Latin letters. A consonant is combined with a vowel, both represented by a Latin letter, to get a character used as a name allotted to the Latin letter. After that, Fan-qui (a traditional Chinese phonetic method) is done with characters used for naming Latin letters. By this way, the obstacle of the phonetic interference of dialects can be removed to great extent. Stroke shape codes are used to identify homonyms and alternative encoding with letters and digits is adopted to drop the ending symbol. Brevity codes are used for frequently used characters.

Patent GB-2143226-A (GB)
Title: Fibre-reinforced hydraulic material
Inventor: MUNOZ PLAZA MIGUEL-JESUS
IPC: C04B28/02
Filed: 1984-05-25
Abstract: A process for preparing fiber-reinforced hydraulic composite material having a high mechanical resistance and durability is characterised by treating the hydraulic binder with compounds in solution (for example, carbonates and bicarbonates of ammonia or of alkaline and alkaline earth metals) at variable concentrations from 0.5 to 20 percent by weight and at different treating temperatures in the range 0 to 99 DEG  centigrade. After setting has occurred this reduces the porosity of the product, increases its mechanical resistance, and causes a reduction of alkalinity of the cement matrix which prevents the degradation of the reinforcing fibres.
Patent GB-2160398-A (GB)
Title: Electrothermal atomiser
Inventor: WIDMER DAVID SYDNEY
IPC: G01N21/74
Filed: 1984-06-11
Abstract: An electrothermal atomiser comprises a tubular member (1) having a dosing aperture (7) situated midway between its ends and two pairs of graphite contact members (2, 4; 3, 5). Two gas entry blocks (30, 35) are urged against the contact members (4, 5) so that a closed volume comprising the interior of the tubular member (1), apertures (15) in the contact members (4, 5) and chambers (31, 36) in the gas entry blocks (30, 35) is formed. Inlets (32, 37) for the flow of protective gas are provided in the gas entry blocks (30, 35) and in addition bleed holes (33, 38) are provided to allow escape of a portion of the protective gas as an addition to the flow through the dosing aperture (7) in the tubular member (1). The provision of the bleed holes (33, 38) enables an increased measured chemical sensitivity to be achieved when the atomiser forms part of an atomic absorption spectrophotometer. By placing the bleed holes (33, 38) opposite the inlets (32, 37) a flow of gas across the quartz windows (34, 39) is produced which reduces the deposition of vapourised sample products on the quartz windows. <IMAGE>

Title: Flat packages for electric microcircuits
Inventor: ROBINSON GERALD BRYAN
IPC: H01B17/30
Filed: 1985-03-28
Abstract: A flat package for electric microcircuits 6 includes a Kovar (R.T.M.) frame 1. Copper wires 2 extend into and are fixed in opposite sides of the frame 1 with glass seals 3, and a Kovar sleeve 4 is provided on each copper wire 2 between that wire 2 and its glass seal 3. With this combination, a large diameter copper wire 2 generates a low amount of heat in the region of the glass seal 3 at high currents of up to 30 amps and a Kovar sleeve 4 of sufficient thickness effectively reduces the coefficient of expansion of the wire 2 in the region of the glass seal 3 to a value compatible with the frame 1. For example, a 1 mm copper wire 2 can be used with a Kovar sleeve 4 of 1.6 mm diameter. <IMAGE>

Title: Alternate cell routing for cellular mobile radio
Inventor: GOLDMAN STUART O
IPC: H04W16/06
Filed: 1986-02-26
Abstract: A method for processing Cellular Mobile Radio Service (CMRS) telephone calls during cell voice channel congestion provides that, when the system receives a request for service (either a mobile originating call or a call terminating to a mobile) which would normally be denied because of cell voice channel congestion, the system can directly select an idle voice channel in other cells which have coverage areas overlapping the coverage area of the cell or cell sector wherein the subscriber is located. Direct selection is accomplished by the use of a routing table containing alternate routes. The table members of the alternate routes are the available voice channels in the other cells. The communication to the mobile to tune to the selected voice channel in the new cell is sent to the mobile via the control channel of the current cell as is done in the cases of either a denial or a directed retry command. <IMAGE>

Title: Axial-piston engine
Inventor: DWORAK WILHELM
IPC: F04B1/20
Filed: 1987-06-02
Abstract: The axial-piston engine has a housing (10) and a cover (11) closing the latter. The two housing parts are connected to one another by means of tie rods (17). The upper parts of the tie rods have screw heads (18) which rest against cover flanges (11A), whilst the opposite ends of the tie rods are fastened in lugs (20) formed on the outside of the housing. These are located in the vicinity of the bearing point of the swash plate (12). This ensures that large regions of the housing are largely relieved of noise- generating flexural waves, since the force flux is transmitted via the tie rods.   <IMAGE>
