Patent GB-2170578-A (GB)
Title: Valve
Inventor: SUTTON DAVID MICHAEL
IPC: F16K31/06
Filed: 1985-12-18
Abstract: A valve for controlling fluid flow, particularly gas flow, comprises a body 101 with portions forming passages 103 and 107 and an annular chamber 105 surrounding the passage 103 which is centrally located within the body 101. A valve member 108 common to each passage can close off opposed ends 109 and 110 of the passages 103 and 107 and form a seal (119, 134) therewith, the valve 108 being spring biassed by a leaf spring 148 to close off the end 109 of the passage 103. The valve stem 136 is connected to an armature 135 of a solenoid (not shown) serving to move the valve 108 upwardly against the bias. The arrangement is such that the valve 108 can occupy a position in which one passage communicates with the chamber 105 while the other passage is closed by the valve 108 or an intermediate position where both passages communicate with the chamber 105. The valve body 101 has internally threaded external ports 113, 124 and 106 leading respectively to the passages 103, 107 and the chamber 105. By-pass ports 150, 151 are provided. The valve can operate as a flow diverter, a flow proportioning valve, a flow selector, or a mixing device. <IMAGE>

Title: Timing system for a circuit tester
Inventor: HEAPS IAN
IPC: G01R31/319
Filed: 1986-02-21
Abstract: The timing subsystem (34) is for an automatic circuit tester (10) and includes an edge generator (36a) comprising two delay sections. The first section (70,72,74,76, and 78) begins timing for an edge at the beginning of a pipeline period in which the edge generator (36a) receives the data that indicate the time at which the edge is to occur. This section completes its timing before the end of that pipeline period. When it does so, it initiates the timing of the second section (80,82,84, and 86), which can continue its operation beyond the end of the current pipeline period. When the next pipeline period starts, therefore, the first section (70,72,74,76, and 78) of the edge generator can be timing the first part of the delay to the next edge while the second part is still timing the delay to the current edge. <IMAGE>

Title: Solid/liquid separator
Inventor: HAIGH MALCOLM
IPC: B01D29/00
Filed: 1986-07-16
Abstract: In a two stage separator for dewatering of sewage, the sewage is fed on to a semi-cylindrical bar screen 20 from which the solids content is swept by a rotating rake (18) into a tank 40A, where a macerator-pump unit 42 chops it up and delivers it, with a fraction of the liquid content which passed through screen 20, through pipe 45 to a weir feedbox 48 and thence on to a second semi-cylindrical screen 28. Rotating brushes, rollers and/or scrapers (26, 50A) sweep the solids from screen 28 into a tank 52. The two screens are axially aligned side-by-side so that their respective rakes and brushes etc can be mounted for rotation on a common shaft (12).

Abstract: A cylindrical image-bearing member (10) especially adapted to a very compact electrophotographic apparatus having a ratio of the diameter to the length of 1:5 or more, can be effectively cleaned by a cleaning blade 20 if the surface of the image-bearing member has a relative frictional coefficient against urethane rubber of 0.7 or less with polyethylene terephthalate film as the standard. Cleaning failure and generation of blade (20) scratches on the image-bearing member can be avoided even if it has a small diameter of 45 mm or less. The cleaning effect is ensured if the cleaning blade (20) line pressure is 7 g/cm or higher. <IMAGE>

Patent GB-864229-A (GB)
Abstract: 864,229. Calculating-apparatus. KOOPERATIVA FORBUNDET EKONOMISK FORENING. Aug. 30, 1957 [Aug. 31, 1956], No. 27379/57. Class 106 (1). A keyboard machine such as an adding or invoicing machine having auxiliary means for automatically operating the keys to enter predetermined groups of digits or other characters, comprises a member movable through the same number of positions as there are digits in a predetermined group in co-operation with a photocell and light source, the arrangement controlling switch means to prevent an incomplete group of digits from being printed. In a calculating- machine a flag 4, Fig. 2, moves stepwise with the pin carriage in response to key actuation initiated by signals derived from a stepping switch 6, Fig. 4. After a predetermined number of steps (five) the arm 7 of the switch moves to the sixth contact normally to initiate a machine cycle. If the flag 4 also has completed five steps it now interrupts a beam of light to a photo-cell 5 causing contacts fc to be transferred to position 2 and thus preparing a circuit from the sixth contact of switch 6 to a machine-actuating magnet Utl. If, however, a fault has prevented the pin carriage with the flag 4 from completing five steps, the contacts fc remain in position 1 and current via the switch 6 causes a relay B to close its contacts b to illuminate a warning lamp S. In another embodiment a larger flag or a strip having a series of apertures (Figs. 5 and 6, not shown) moves between the light source and the photo-cell. Light passing through an aperture to the photo-cell causes closure of contacts #c, Fig. 7, and energization of a solenoid C which operates a stepping switch 12 additional to the controlling switch 6. After five steps the arms of both switches will normally be in the fifth position, and when therefore the switch 6 moves to the sixth position a circuit will be completed through the machine-actuating magnet Utl. If, however, the switch 12 has not reached the fifth position at this time, the circuit of a relay B is completed and this lights a warning lamp S as in the first embodiment.

Title: "Failure detection for an automatic transmission"
Inventor: ITO YASUNOBU
IPC: F16H61/08
Filed: 1988-12-21
Abstract: A first sensor (1) senses the rotational speed of an input shaft of the transmission (9) and a second sensor (2) senses the rotational speed of the output member of the transmission or senses the vehicle speed. During a gear change, the device measures the time for the ratio between the measured input and output speeds of the transmission to change from the formal gear ratio (i.e. the ratio ignoring any slip) before the change to the formal gear ratio after the change. The device checks whether or not the time (TS1) so measured falls within a predetermined range of acceptable times for the gear change in question and for the gear change conditions such as throttle opening. If the time (TS1) does not fall within the predetermined range, the device determines that there is a fault and sets the transmission in an emergency control mode and operates an alarm device so that the driver can note the need for repair.
