Title: Screen printing apparatus
Inventor: BAYLISS ROBERT VIVIAN
IPC: B41F15/10
Filed: 1990-03-23
Abstract: A control system for use on a screen printing apparatus for assisting correct registration of subsequent images screen printed on a substrate at a screen printing station includes an electronic scanner (86) for locating the image of a print or marker printer on the substrate, and an encoding disk attached to a printing drum (16) with a further scanner to measure the rotational movement of the printing drum from which the expected position of the image of a print or marker can be determined. Processing means is provided for comparing the located image position with the expected image position and for effecting connectional movement of the printing screen (18) by means of a stepper motor (85) controlled by the processing means. The control system is employed in a four-colour screen printing apparatus which includes a plurality of printing stations (2, 4, 6, 8) in which the substrate is moved in a first direction through first (2) and second (4) printing stations, and in a direction substantially opposite thereto through the third (6) and fourth (8) printing stations. <IMAGE>

Title: Fluid flow control system
Inventor: TAYLOR STEPHEN ALAN
IPC: G05D7/00
Filed: 1992-07-24
Abstract: A fluid flow control system has a vortex valve 1 combined in series with a non-fluidic control valve 6, eg a butterfly valve. Also, a further flow line 4 is connected at one end to a flow line 2, containing the two valves, upstream of the non-fluidic control valve, and at the other end to the control ports of the vortex valve. This flow line can form or can include a flow restrictor to provide required divisions of flow between the lines 2 and 4. With this arrangement, small changes in the control state of the non-fluidic control valve produce significant changes in the flow resistance through the vortex valve. As a result the problems of erosion and cavitation in the non-fluidic control valve are reduced with a consequent improved life therefor. <IMAGE>

Title: Processing digitally sampled data
Inventor: CAMPBELL ANDREW
IPC: H04H60/07
Filed: 1992-11-25
Abstract: For processing input channel status data associated with encoded input data from at least one input channel to form output channel status data associated with encoded output data for at least one output channel where the encoded input data include input data samples at a first sample rate and the encoded output data include data samples derived from the input data samples but at a second sample rate, output channel status data are generated either by omitting selected input channel status data where the output sample rate is lower than the input sample rate or by duplicating selected input channel status data where the output sample rate is higher than the input sample rate. Input channel status data are temporarily buffered in a memory 20 under the control of a write state machine 22 which controls the writing of selected input channel status data to the memory and a read state machine 24 which controls the reading of selected input channel status data from the memory 20 to form the output channel status data. The write and read state machines are responsive to an input channel clock C11 and to an output channel clock C12, respectively, and to each others states. <IMAGE>

Patent GB-2277803-A (GB)
Title: Microwave moisture determination
Inventor: ASSENHEIM JERRY GEOFFREY
IPC: G01N22/04
Filed: 1993-05-05
Abstract: A moisture measuring system uses the technique of measuring both parameters of the complex dielectric constant of the material containing water to correct for the density of this material. The electromagnetic field of a microwave resonator is allowed to link with the moist sample and the changes in Q factor and resonant frequency of the resonator are determined. The change in frequency is measured by a technique comparing the phase of the voltage in the resonator with the phase of a voltage due to the delay in a coaxial cable. Two microwave diodes D1, D2 rectify the difference between these two voltages to produce an output which is a linear function of the small frequency change. A simple analogue circuit is proposed to use the two parameters obtained to obtain a reading of moisture which is independent of density of the material. <IMAGE>

Title: Data buffering between processors.
Inventor: HEJDEMAN CARL RON
IPC: H04L13/08
Filed: 1994-04-12
Abstract: A data buffering device (33) is positionable between communicating processors (21, 22). At least one of the processors is battery powered and is arranged to be placed in a stand-by condition when not required to process information, thereby reducing overall power consumption. The data buffering device includes data storage locations (34,41) and means (42, 43) for addressing these locations to effect the transfer of data to or from the memory locations. In addition, interrupting means (42, F1, F2, G1) are provided for generating interrupt signals arranged to interrupt at least one of the processors. Thus, upon receiving an interrupt signal, a communicating processor is switched from its stand-by mode to an active mode and data transfer is effected. Data transfer may take place in both directions and respective buffering means, with respective interrupt signal generating means, are provided. The device may be used in a mobile cellular telephone, positioned between a controller and a digital signal processor. <IMAGE>

Title: Effluent treatment
Inventor: CROCKER PETER JOHN
IPC: C02F1/66
Filed: 1994-08-13
Abstract: An effluent which may contain both complexing agents and potentially-toxic heavy metals is treated by first acidifying to pH below 4, adding a ferric salt, and leaving for a prolonged time.

IPC: G01R31/74
Filed: 1995-08-11
Abstract: A simple fuse-testing device comprises a lidded container (11) carrying an indicator device (19: this may provide one or both of a visible and audible indication, such as that from a diode or a buzzer) and divided internally into compartments (12, 13) for retaining a battery (31) and a multiplicity of spare fuses.
