Title: Polling for detection of power supply or other failures of a digital circuit
Inventor: TAN SIEW MENG
IPC: H04N5/63
Filed: 1992-05-01
Abstract: A television receiver includes a standby power supply (ST), and an operational or run mode power supply (U2, X2). A microprocessor coupled to the standby power supply controls switching between a run mode, where the standby and run mode power supplies are operative, and a standby mode where only the standby supply is operative. The switching is normally made in response to switch inputs or in response to a signal from a remote controller. The microprocessor is in digital communication with a digital circuit, such as a phase locking tuner, over a bidirectional data bus. The microprocessor is programmed to poll the digital circuit periodically and to monitor the data on the data bus for an expected response to a poll. When the digital circuit fails to respond to the poll, or responds inappropriately, as may occur with lack of adequate power to the digital circuit from the run power supply, the microprocessor automatically switches into the standby mode and disables the run supply. The microprocessor switches back into the run mode upon command, unless data stored in memory indicates a recent or repeated automatic change into the standby mode after a detected failure. <IMAGE>

Title: A method of mining seams to a defined preset depth of cutting
Inventor: GEUNS GUY
IPC: E21C35/24
Filed: 1992-05-26
Abstract: A method of working coal seams to a defined preset cutting depth during ploughing with a cutter 2, a face conveyor 3 moving along a face behind the cutter 2 being advanced by the defined preset cutting depth and this advance being made by extension of self-advancing cylinders 4 pivotally attached at one end to the face conveyor 3 and at the other end to face supports 5 disposed parallel to the face conveyor 3. The advance is controlled in dependence upon the piston stroke of the self-advancing cylinders 4, carried out in dependence upon individually defined partial strokes corresponding to the preset depth of cutting. After a predetermined maximum total piston stroke has been reached, the face support 5 connected to the respective self-advancing cylinder 4 is automatically disengaged, advanced by the maximum total piston stroke and then re- set. The length of the partial strokes corresponding to the preset depth of cutting is increased by an amount to compensate an average mechanical clearance at the pivot points of the self-advancing cylinders. <IMAGE>

Patent GB-2269080-A (GB)
Title: Constant picture size for crt displays despite scan frequency changes
Inventor: MORRISH ANDREW JOHN
IPC: H04N3/27
Filed: 1992-07-25
Abstract: The deflection comprises a ramp generator 210 for producing a current ramp signal synchronised to a raster synchronisation signal. A ramp regulator 230 is connected to the generator 210 for varying the amplitude of the scan signal as a function of the difference between a reference input and a feedback signal. A feedback circuit 220 is connected to the generator 210 and to the regulator 230 for generating the feedback signal as a function of the amplitude and frequency of the line scan signal. A multiplier 250 is connected to the regulator and for varying the reference input is a function of an integer multiple of the frequency of the raster synchronisation signal. Any scan signal frequency component in the feedback signal is cancelled at the input to the regulator by introducing, via the multiplier 250, a scan signal frequency component to the reference input. Because the displayed picture size is thus made independent of scan signal frequency, the deflection apparatus can maintain a constant picture size despite variations in scanning signal frequency without the bandwidth limitations of the prior art. <IMAGE>

Title: Wave solder machine with dross suppression function
Inventor: BEVAN PETER RYLAND
IPC: B23K3/06
Filed: 1994-09-07
Abstract: In a wave soldering machine, stainless steel diffuser tubes (11f, 11r) (with apertures constructed as mesh, the size of which is not less than 7  mu M or greater than 170  mu M), are located near the position where the solder waves (3f, 3r) fall into the solder (3). They are covered by stainless steel housings (14f, 14r) on the upper side thereof. Dross production is thus suppressed by approximately 80%. Also a conveyer includes a sensor device for detecting the presence or absence of printed circuit boards so that in their absence, the circulation of the solder is stopped or performed at an idle speed so that no solder waves (3f, 3r) are produced. Furthermore the supply of the inactive gas (eg. nitrogen) to the diffusers (11f, 11r) is switched off in these circumstances. <IMAGE>

Patent GB-942562-A (GB)
Abstract: 942,562. Labelling machines. W. PECHMANN. July 15, 1960 [July 25, 1959; Nov. 12, 1959], No. 24792/60. Heading B8F. Relates to a labelling machine for labelling bottles, ampoules into which are fed on a band conveyer 11, Fig. 1, to a labelling roller 12 receiving labels from a magazine 20 via a rotating segment 21 on which the labels are gummed by rollers 23, 24. According to the invention a reciprocating blocking slide 28 adjacent to and associated with the roller 12 is interposed in the path of the containers and permits feeding of the containers to the roller 12 individually and at a point of time corresponding to the label feed. The blocking slide 28 comprises prongs which, as shown, are guided in grooves in the bearing block 29 of a feed worm 18, and which are pivotally mounted at 30 to a two-sided frame-like lever 26 pivoted at 27. A cam disc 12b mounted to rotate with the roller 12 engages the lever 26 and controls the reciprocating movements of the prongs 28 in their guide grooves, the arrangement being such that a container is held by the prongs 28 until such time as a label on the rotating roller 12 is in a position to meet the container, the prongs 28 then being withdrawn from the guide grooves to release the container. As shown, a band 14 runs around the roller 12 and another roller 13 and a parallel band 15 runs over rollers 16, 17. In the case of square bottles or other bottles of non-circular section, the two bands 14, 15 are run at the same constant speed but, as shown, with bottles of circular section, the speed of the band 15 is varied such that at first the container is rotated in one direction and then in the other direction in order to apply firmly the lateral ends of the labels. Rollers or small wheels which engage the containers may be resiliently mounted on the blocking slide 28. In another embodiment for labelling bottles of eliptical section, the band 15 is replaced by a chain 52, Fig. 3, carrying resilient and divided pockets 55 shaped to receive the bottles and for satisfactory passage over the rollers 57, 58. The blocking slide 28 serves to hold the bottle for a very brief instant until the bottle has been correctly positioned in the pocket 55. In a further embodiment, Fig. 4 (not shown), the blocking slide 28 is mounted at the other side of the roller 12 and its prongs pass between the individual belts of the band 14. The arrangement for the movement of the prongs is also modified in this embodiment, but the movement is controlled by a cam disc 12b rotating with the roller 12.
