Patent GB-969353-A (GB)
IPC: D06L4/23
Abstract: 969,353. Absorption-desorption cycles for gas separation. BRITISH PETROLEUM CO. Ltd., A. A. YEO, and R. T. L. MOWLL. Oct. 23, 1962 [Nov. 3, 1961], No. 39433/61. Drawings to Specification. Heading B1L. [Also in Division C5] In a cyclic absorption-desorption process using one or more fixed beds of absorbent for separating gases, e.g. hydrocarbons, the switching of an outlet valve or valves to collect the next effluent from a bed is delayed beyond the switching of an inlet valve or valves to change the feed to the bed so that material present in the void between absorbent particles when the inlet valves are switched is removed from the absorber before the outlet valves are switched in an amount up to 90%. An intermediate purge step may be employed to give an absorption-purge-desorption cycle, and four beds may be used so that at any given time one bed is absorbing, one is being purged and two are being desorbed. The process is described in relation to the separation of n-paraffins from C 4 -200 ‹C. and 200-400 ‹C. B.P. petroleum distillate fractions with 5Š molecular sieve particles isothermally and isobarically at 200- 600 ‹C. and 0-500 p.s.i.g. using nitrogen as purge gas and n-butane or n-pentane, diluted if desired with nitrogen, as desorption gas.

Title: Preventing charging of primary cells
Inventor: AKIYA MAKOTO
IPC: H02J7/00
Filed: 1997-07-17
Abstract: A charger 11 is provided for charging a battery of an electronic equipment (such as mobile communication equipment) which can use a battery of primary cells or a battery of secondary cells. The charger prevents erroneous charging of primary cells by discriminating between secondary and primary cells according to the presence or non-presence of voltage at an auxiliary terminal, 2a or 2b, on a battery case 6. Non-presence of voltage at that terminal may indicate that the case 6 contains secondary cells, and presence of voltage that the case 6 contains primary cells, a series string of primary cells 3 (Fig.2) having intermediate connections connected to terminals 2a, 2b for example. Alternatively, non-presence of voltage at the auxiliary terminal may indicate primary cells, and presence of voltage may indicate secondary cells. An audible or visual alarm 16 may be activated to indicate that charging is being carried out when a secondary battery has been detected, or alternatively such an alarm may be activated to indicate that charging is not being carried out when a primary battery has been detected.

Title: Vehicle having position sensors assigned to the wheels
Inventor: KUTSCHER EBERHARD
IPC: B60C23/06
Filed: 1997-11-06
Abstract: A device for determining the position of the centre of each wheel (1-4) of a vehicle relative to the portion of the body of the vehicle vertically above each respective wheel. Sensors (6-9) are arranged on the body of the vehicle and provide signals to a computer (14) representative of the said relative positions. The computer (14) generates a time-average of the relative position of each wheel (1-4). The displacement of the time-averaged relative position of one wheel of the vehicle from a plane (13) defined by the aforementioned relative positions of three of the other wheels of the vehicle, is determined by the device. Should the time-averaged position of the one wheel deviate excessively from plane (13) a warning signal is issued to the driver via warning display (16). Such a warning signal would be issued in the event of a sufficient drop in pressure in the tyre associated with the aforementioned one wheel i.e. the drop in pressure and resulting tyre deflation causing a displacement of the wheel (1 of Fig. 2) from the plane defined by any three of the other wheels, each of the latter having fully inflated tyres.

IPC: E05B65/464
Filed: 1998-04-14
Abstract: A locking device for furniture drawers C consists of guide strips (21 ...) For each drawer sliding in a fixed guide 1, one strip carrying a seat 22 and another a cam assembly 23.

Filed: 1998-09-17
Abstract: An active pixel sensor with an electronic shutter is capable of obtaining an auto exposure function so that all pixels have the identical photosensitive time to enable a uniform brightness across a display screen. Means such as a diode D1 for generating a photo-electric charge in accordance with light incident thereon is connected to means M2 for amplifying the charge and means M3 for outputting the charge in response to a selection signal. Switching means M4 passes the charge for a predetermined time in accordance with an externally inputted shutter control signal to means M5 for storing the charge for a predetermined time. The charge from the storage means M5 is supplied to the amplifying means M2, and the storage means is reset in accordance with an electric charge resetting signal.

Title: Clipping device with gripping means
Inventor: WU SHIH-PIAO
IPC: A01G3/02
Filed: 1999-09-22
Abstract: A horticultural clipping device has both a finger grip's blade (111) and a palm grip's blade plate (121). These blades respectively have a press base (2) and a clamp base (3). Both the press base's surface and the clamp base's surface have a full row of shallow teeth (21,31). Within the press base a spring clip (2A) is fitted. In this way, when the clipper is cutting, as the blade (111) is dropping down upon the blade plate (121), the press base (2) drops down upon the clamp base (3), which is attached and next to the blade plate. Thus, after clipping a plant stem, the cut parts are held securely between the press base (2) and clamp base (3). This prevents parts from falling and eliminates the user's inconvenience of having to pick up clippings.

Title: Steam accumulator with centrifugal separators
Inventor: OAKLAND DAVID
IPC: B01D45/12
Filed: 1999-10-01
Abstract: A steam accumulator 5 is provided with centrifugal separators 4 which remove water from the steam as it is discharged. The accumulator stores surplus steam from a boiler 1 in water. When steam is required, a pressure drop is allowed to occur in the space above the water, causing steam to evaporate from the water. Any mist or water entrained in the steam is removed by the centrifugal separators, so that near dry, saturated steam is supplied to the outlet pipeline 6. The provision of the centrifugal separators means that the water surface area and therefore the size of the accumulator can be reduced.

Title: Executing debug instructions
Inventor: JAGGER DAVID VIVIAN
IPC: G06F11/36
Filed: 1999-12-10
Abstract: A main processor 4 is driven by a main processor clock signal clk at a main processor clock frequency and debug logic ( coprocessor 6, and JTAG12) has at least a portion (JTAG 12) which is driven by a debug clock signal tck at a debug clock frequency. The debug clock frequency tck is different and asynchronous to the main processor clock frequency clk. The instruction transfer register ITR receives data processing instructions which may be transferred by the debug logic 12 and which may be read by said main processor 4. When the processor 4 is switched from a normal mode to a debug mode it continues to be driven by the main processor clock signal clk executing no-operation instructions until a data processing instruction is present within the instruction transfer register ITR and the debug logic 12 triggers the processor 4 to read and execute the data processing instruction whilst still driven by the main processor clock signal clk. This arrangement allows debug instructions to be executed at full speed whilst avoiding the need to switch clock speeds and provide a synchronisation mechanism. The processor 4 also has separate scan chains for instruction transfer and data transfer to/from debug logic.
