Title: Subscriber communication channel equipment
Inventor: WEBER DR JENS
IPC: H04B10/80
Filed: 1983-10-24
Abstract: Subscriber communication channel equipment is switched to a stand-by-state if they are not operated. In the stand-by-state only those components are fully operative which are necessary for switch-over to the normal operation state. The switch-over to the operation-state is effected by a logic signal "ON" which connects the supply voltage to a parallel/series- converter 2 which transmits together with the data stream D, a bit timing signal BT to an electro-optical-converter 3. After detecting the bit timing signal BT the electro-optical-converter 3 is switched on and the light signal is transmitted on an optical fibre transmission line to an opto-electrical- converter 4. After detecting the light signal the opto-electrical-converter 4 sends data and bit timing signals to a series/parallel-converter 5. After detecting the bit timing signals the series/parallel-converter 5 is switched on. <IMAGE>

Title: Facilities control
Inventor: TASHIRO TSUTOMU
IPC: G06Q50/04
Filed: 1984-05-02
Abstract: A condition-responsive control arrangement for facilities, e.g in an automated factory, provides for receiving status signals from the facilities and delivering command signals responsive to the status signals to the facilities. Upon the generation of a status signal, the identity number of a rule set (control logic) for use is determined; a corresponding internal code (Fig. 3b) is generated from the status signal on the basis of look-up data stored in memory means; the corresponding coded rules are read out from another memory means on the basis of the identity number of the rule set; the internal code of a final control command is decided by referring to a further memory means (50, Fig. 5B) which stores codes of conclusions formed on the basis of the coded status signals and the applied coded rules; and the command signal for a facility is generated from the internal code of the decided control command by referring to the stored look-up data. The use of internal codes provides faster data processing than in prior art arrangements using character strings. <IMAGE>

Filed: 1985-06-28
Abstract: A dispenser for drinks, e.g. beer, comprising a cock with a casing (1) having a passage (2) in which a cock closure spool (4) is displaceable. An actuator mechanism for the spool is connected to a control drive and has a double-acting solenoid (16) which is mounted on the outside of the casing and an actuator member (18) of which is coupled to the cock closure spool (4) via a rocking lever (11, 13). The control device for the double-acting solenoid is a time control device via which the double-acting solenoid may be shifted out of a starting position, as shown, in which the cock closure spool blocks the passage (2) in the casing, into two working positions in opposite directions, in one of which the spool connects substantially the whole cross-section of the casing inlet (2''') to the casing outlet (3) to deliver liquid only, and, in the other of which, a restricted cross-section (10) of the inlet is connected to the outlet to deliver froth. In the one working position lever knobs (11', 11'') have moved the spool (4) to the right, and sealing ring (5) moves with the spool off its seating at the inlet (2'''). In the working position, lever knobs (11''') have moved the spool (4) to the left, and sealing ring (5) firstly comes to rest on its seating at the inlet (2'''), and thereafter, the spool (4) continues to move relative to the ring (5) so that a radial mouth of a bore (10) in the spool is exposed. <IMAGE>

Title: Producing alumina-silica sintered ceramics
Inventor: OHTA SHIGETOSHI
IPC: C04B35/18
Filed: 1986-06-05
Abstract: A process for producing alumina-silica sintered ceramics, the strength of which at temperatures up to 1,300 DEG C is higher than their room temperature strength, is characterized by employing a powder mixture which is free from the defect of heterogeneity being present in the starting material prepared by the prior art. The powder mixture is attained by: synthesizing from a solution obtained by mixing Si and Al sources; adjusting the ratio of Al2O3 content to the sum of Al2O3 and SiO2 contents in the powder mixture to the range of 60-73%; and adjusting the amounts of impurities in the powder mixture to no more than 2,500 ppm. If the appropriate proportion of Al2O3 is selected, sintered ceramics having a high-temperature strength which is nearly 1.5 times their room temperature strength can be obtained.

Title: Hammer unit for printers
Inventor: NOTSU RISEI
IPC: B41J9/133
Filed: 1986-07-02
Abstract: This invention provides a hammer unit for use in character printers in which the front end of a plunger (2) of a solenoid (1), operating under control of the print command, is positioned directly opposite to and close to the typeface (7) of the character head. The plunger is provided with a plunger tip (3) which can be attached to and detached from it in a direction perpendicular to the axis of the plunger and which covers part the cylindrical side surface of the plunger and the entire circular end face of the plunger front end. At least the cap part (5) of the plunger tip (3) covering the front end of the plunger being made of synthetic resin material. When the plunger tip (3) has to be replaced owing to wearing out of its cap part, the plunger tip can be replaced easily and quickly by slipping it on and off the plunger in a direction perpendicular to the axis of the plunger. Furthermore, since the print stroke is determined in such a unit by the stroke of the plunger and thickness of the cap part of the plunger tip, adjustment of the print stroke is easy. <IMAGE>

Title: A fuel vaporiser
Inventor: SOTHERAN ARTHUR
IPC: F23D11/00
Filed: 1987-08-28
Abstract: A form of T-shaped fuel vaporiser for a gas turbine engine is described in which the vaporiser mixture outlets are defined by a generally oval shaped cap joined to one end of a vaporiser stem. The outlets are defined by a cap rim and part of the wall of the stem so that the latter is washed on both sides by the fuel/air mixture. The arrangement eliminates hot spots which tend to occur with T-shaped vaporisers on the inside bends of the cross-piece and outlets, but without sacrificing the desirable flow distribution characteristics of a T-shaped vaporiser. <IMAGE>
