Patent FI-991246-A (FI)
Inventor: KANGAS ARTO
IPC: H04B7/005
Filed: 1999-06-01
Abstract: The invention concerns a method for measuring the quality of a radio link in a radio packet data connection in a cellular radio system for telecommunication. According to the invention, the mobile telephone measures the level at reception of data blocks in the downlink control channel, wherein the data block contains control information addressed to the mobile telephone, and reports the measured data to the network. Based on the measured data, the network monitors the transmission power for the packet being sent at the downlink control channel so that all mobile telephones for which the packet contains information can successfully decode the packet. <IMAGE>

Title: Offset keying technique for segregation phase comparison relaying
IPC: H02H3/30
Filed: 1976-01-13
Abstract: 1531571 Line protective systems WESTINGHOUSE ELECTRIC CORP 13 Jan 1976 [7 Feb 1975] 01230/76 Heading H2K In a system for determining whether a fault on a line is internal or external to a protected section by deriving two measuring signals respectively representing current conditions at each end of the section, converting these to trains of rectangular pulses and then determining whether the pulses of the two trains coincide, the pulses in each train correspond to periods for which the associated measuring signal is exceeding a respective threshold which is not zero (i.e. the pulses do not simply represent the positive or negative half-cycles of the measuring signal). This ensures that high-resistance internal faults, where the fault current is less than the normal line current, will be recognized even though the currents I L , I W  (Fig. 5) at the two ends appear to have a satisfactory phase relationship.  The invention may be embodied in the system described in Specification 1,494,682, in which from a measuring signal (16) at one end are derived (67) a first pulse train I SW  for transmission to the other end, and the second and third pulse trains I SWP , I SWN  for comparison with the pulse train RI SW  received from the other end and its inverse respectively. The transmitted pulses I SW  (and correspondingly, of course, the received ones RI SW ) are made to correspond to the instants at which the local (or far) end measuring signal exceeds a negative threshold, e.g.-4À5A, which is slightly less than the peak value of the measuring signal (e.g. 5A) under normal full-load conditions. The pulses I SWP  are only produced when the signal exceeds a positive threshold (6A) which is normally never reached, whilst the pulses I SWN  correspond to the instants at which the signal is below a positive threshold (3A) less, in absolute magnitude, than the threshold for the transmitted/received pulses I SW , RI SW .

Title: Mechanism for reversing oil engines by means of preignition
IPC: F01L13/00
Filed: 1923-01-23
Abstract: 212,042. Harris, A. J. Jan. 23, 1923. Reversing.-A device for reversing oil engines by means of an early injection and ignition of fuel comprises a collar 5 loosely mounted on the cam shaft 2 near the pump cam 1, pairs of levers 9, 10 and 12, 13 pivoted to the collar, and means for moving the collar to bring one or other lever of each pair into position to engage the corresponding one of the pump plungers 3, 4 when the lever is actuated by the cam. The levers of each pair are mounted on a common pivot 11, 14, and the levers have raised portions 15 - - 18 extending into the path of the cam, so that the cam actuates one lever 9 on meeting its free end 30 and the other lever 10 on passing the pivot and therefore at a different phase point. The collar 5 is adjusted angularly about the shaft 1 by means of a handle 6, and pivoted fingers 19, 22 are interposed between the free ends of the levers. In order to reduce friction, a collar 25 integral with a fixed plate 26 fits the cam shaft 2 loosely and is provided with raised portions 29 which take the weight of the collar 5 and attached parts when the shaft 2 is vertical. In normal running, the collar 5 is turned so that the parts 16, 18 of the levers 10, 13 are under the pump plungers 3, 4. For reversing, the collar 5 is turned into the neutral position, Fig. 1, until the engine slows down, and then into the position in which the parts 15, 17 are under the pump plungers. As soon as reversal is effected, the collar 5 is returned to the original position. In order to prevent the premature movement of the collar 5 from its neutral to its reversing position, the lever 6 may be suitablv connected to the sliding collar of a centrifugal governor.

Cylinders and like elements, rotating.-In an optical-projection advertising device having a series of slides mounted on the periphery of a preferablv internally-illuminated drum 17 rotated step-by-step, the motion is conveyed to the drum by mechanism shown in Fig. 3. A series of pivoted catches 8 carried by a slowly rotated disc 4 loose on the drum shaft engage a sliding nose 10, thus withdrawing a pivoted pawl 13 against the action of a spring 14 which returns the pawl and advances a ratchet-wheel 16, fixed on the drum shaft, after each catch 8 has passed by. Means is also provided for operating spring-controlled sliding shutters 20 - - 23 which uncover the projection opening 19, Fig. 2. and may be used to spell out lettering. The retracting means comprise mutilated gear-wheels continuously rotated by gearing 33, 35 from the disc 4 and engaging racks 31 on the shutters 20, 21, 23. The shutters 22, 23 are connected together by rack and pinion gear 24, and so move in opposite directions to expose the middle part of the opening 19 from the centre outwards. The shutters 20, 21, 23 when retracted are held by gravity or spring-operated hooks 27 which are actuated to release the shutters, to enable them to close the opening 19, by pins 5, 6. 7 on the disc 4. The pins 5, 6, 7 may be pivotally mounted so as to be turned out of the path of the hooks 27 if desired. The Provisional Specification states that the shutters may be withdrawn by pins on a rotating disc engaging with fingers on the shutters.

A device for feeding bar stock 11 into an automatic lathe 100 comprises a bed 10 with a channel 12 housing an endless chain 14 which carries a pusher member 19. Secured to the bed are end posts 28 and intermediate posts 29. Each post has a front portion 30 and a rear part 31 with a vertical magazine opening 32 in between disposed above the bar feed guide 26. Extending the full length of the front of the bed is a mounting angle 47 carrying levers 50 the front ends of which are connected to a rod 51. At one end of the rod is an operating lever 52 with a forked end 54 which engages a peg 55 on the pusher member 19. The rear end of each lever 50 is pivotally connected to a support and cover member 56 which extends over the whole length of the bed to a magazine 32 and is formed in equal sections corresponding to the spaces between the supports 28, 29. A movable stock bar separating member 62 of angle form is pivoted at 42 on the front portions 30 of the posts 28, 29. The movements of the separating member 62 and the support and cover member are synchronized by means of a lever 75 connected to the rod 51 which actuates a rod 72 from the cam surface 73. In operation bar stock 11 is fed to the lathe intermittently at a slow speed and when the bar has been used the pusher member co-operates with a switch 24 and is rapidly returned along the bar feed guide 26. Prior to reaching its extreme returned position the lever 51 is operated causing simultaneous movement of the cover means and the separating member so that the lowest bar falls into the feed guide 26. The pusher 19 then actuates a switch 23 to recommence the feed sequence. Specification 797,351 is referred to.
