Title: Drive station for mining machines and conveyors
Inventor: BRIEHL GERHARD
IPC: B65G23/36
Filed: 1993-12-13
Abstract: A drive station for winning machines and scrape chain conveyors used in mining operations comprises a main drive and an auxiliary drive, each drive having a measuring and control unit 7 for a drive motor 1 and safety slipping clutch 6. During heavy start and heavy run respectively, a control sensory means detects the undershooting of a limit speed of the drive motors, which is preselectable according to a program, and a drive control shifts simultaneously or successively into a slow speed step. After overshooting a preselectable limit speed of the slow speed step, the drive control shifts into the fast speed step. Moreover, the drive force of the safety slipping clutches can be adjusted during the starting process. <IMAGE>

Title: SAW filter
Inventor: MORGAN DAVID PICTON
IPC: H03H9/02
Filed: 1994-04-25
Abstract: The filter comprises a group of N tracks, where N is an odd integer greater than 2, each track including an input interdigitated transducer (IDT) 101a - 101c spaced apart from an output IDT 101d - 101f. The respective tracks are selectable to have different effective electro-acoustic lengths such that surface acoustic waves launched from respective input IDTs undergo at least one reflection at corresponding output IDTs and at least one reflection from the respective input IDTs prior to generating coherent signals from respective output IDTs. The different effective electro-acoustic lengths may be substantially provided by there being different physical separation between input and output IDTs of respective tracks, or by IDTs of respective tracks having different polarity connections of electrodes or different amounts of material deposited in respective tracks between the input and output IDTs. <IMAGE>

Patent GB-2296902-A (GB)
Title: Motor cycle front suspension arrangement
Inventor: HILL NIGEL JOHN
IPC: B62K25/08
Filed: 1995-01-16
Abstract: The front suspension comprises a pair of telescopic struts each having a stanchion,21, and a cylinder 22,23. The upper parts of the cylinders, 22, 23, are linked together by a brace 25, which is in turn pivotally linked to the frame by a radius arm 15. The radius arm imposes a lateral load on the strut cylinders 22, 23, and thereby promotes wear. Lubrication of the strut is ensured by a lubricant chamber formed in the base of the cylinder, from which lubricant is transferred by the action of compressing the strut, to the wearing surfaces, 30, at the upper end of the cylinder.

Patent GB-2299636-A (GB)
Title: An expansion joint
Inventor: MCNEELA ANN
IPC: F16L59/18
Filed: 1995-05-11
Abstract: An expansion joint has side walls (4) which have a large exposed surface area for radiation of heat (7). Heat transfer to the side walls (4) is reduced by a configuration of base insulation (5). Heat transfer through clamps is minimised by use of insulating washers (15). Heat which reaches the clamps is radiated with the help of channel-shaped clamping members (11). A fabric belt (10) extending between the clamps has a graphite glass cloth protective cuff 20 and a layer 27 which provide insulation and strength. A band (25) of insulation helps to reduce heat transfer but does not extend across the free part of the fabric belt (10) so that temperature on the inside of a chemical PTFE layer (23) is not reduced to the extent whereby there is condensation when gas passing through the joint is at the operating temperature. However, additional protection is provided for an outer silicone cloth layer (21) by an insulating layer (22) which does not extend into the clamped area.

Patent GB-2306086-A (GB)
Title: Improved adaptive audio systems
Inventor: TRIM RICHARD MORRIS
IPC: H04R27/00
Filed: 1995-10-06
Abstract: A Public Address System employing a sample and hold technique, in which the level of acoustic output is adapted to the prevailing levels of acoustic noise, so as to minimise noise pollution and to maximise intelligibility. In the absence of public address announcements, the sample-and-hold circuit 2 constantly adapts the gain 1 of the public address system message channel such that if an announcement were made, its acoustic level would be appropriate to the prevailing level of acoustic noise at the time that the message began. In this way, the ambient noise sampling system is prevented from confusing the acoustic level of the PA message with acoustic ambient noise, thus avoiding regenerative "lock up". Noise signals picked up by a microphone 11 are applied to the sample and hold circuit 2 via circuitry 12-22. The sampling is inhibited by circuitry 3-7 responsive to the message signals. The sample and hold circuit is briefly enabled during pauses in the message for updating, the gain to current noise levels. A monostable 7 is for inhibiting changes caused by echoes, reverberation. An attack and decay circuit 18 prevents changes in noise output caused by transient phenomena e.g. coughing.

Title: Image data manipulation in buffer of controller for bulk storage device
Inventor: BRETT STEHEN
IPC: H04N11/04
Filed: 1996-04-09
Abstract: A bulk storage controller having a memory for buffering data which has been requested from the bulk storage permits the modification of buffered data prior to onward transmission. The data in the buffer are used to index into a RAM containing a look up table and data from the corresponding addresses indicated in the look up table are written back into the buffer. The data may be image data and the look up table may be a colour cube for introducing colour or textural corrections, possibly with interpolation. Cubic and tetrahedral interpolation schemes are used. The colour cube look up table may be targeted at specific colour ranges eg. to prevent the modification of reserved colours used for "blue screen" techniques.

Title: Handling telephone calls in an Intelligent Network having distributed service logic
Inventor: JELLEMA BART
IPC: H04M3/42
Filed: 1996-07-19
Abstract: Service logic is distributed over a number of service control points in an Intelligent Network. In response to a call 22 from an end user (8, Fig. 1), a service switching point (SSP 6) sends a query 24 to a first service control point (SCP). If the first control point determines that at least part of the query should be dealt with by a second control point, the first control point sends a message (handover instruction 28) to the switching point instructing it to send a query (32) to the second control point. A response sent from the second control point to the switching point may instruct (36) the switching point to direct a further query (38) to the first control point or to a third control point. The switching point may use different protocols for communicating with different control points. The network may include control points located close to respective users and containing service logic relating to the more common parts of a service, and a centralised control point which executes a more specific part of the logic and is queried by a large number of switching points.

Title: Automatic blind or curtain operating system
Inventor: BELL DAVID
IPC: E06B9/32
Filed: 1994-01-14
Abstract: An electric motor 44a moves a suspension device 28 along a headrail 10 or pole towards and away from a stop 48 to open and close the blind or curtain. An automatic controller 12 is provided which detects a monotonic increase in current to the motor 44a associated with drive from the motor 44a being taken up by the springs 50 as the stop 48 is reached and interrupts current to the electric motor 44a when the increase in motor current is detected. The controller also stores the position of the suspension device 28 when the increase in current is detected and drive to the electric motor 44a during subsequent operation of the system is then regulated to interrupt current to the motor before the suspension device 28 hits the stop 48 again.
