Abstract: 1303291 Ramp generator G & E BRADLEY Ltd 29 June 1971 [6 July 1970] 32712/70 Heading H3T A ramp wave generator comprises two complementary transistors having their collectoremitter paths in series between supply lines and their commoned collectors coupled to a capacitor through a diode, the capacitor being charged from a substantially constant current source when one transistor is on and discharged via the diode and the other transistor when said one transistor is off. A trigger pulse 15 sets bi-stable 41 to turn on transistor 35 thereby raising the voltage at 81 to reverse bias diode 28 and permit bootstrap circuit comprising transistors 23, 24, 27 and resistor 18 to charge the capacitor 19. A level detecting circuit 82 sets bi-stable 72 when the ramp waveform 16 reaches a particular voltage level so causing transistor 35 to turn off and thereby forward biasing diode 28 to discharge the capacitor 19 via resistors 29, 31 and transistor 30. The rate of discharge of capacitor 19 is arranged to be faster than the rate of discharge of the integrator comprising capacitor 84 and resistor 85 so that after the capacitor voltage is caught by diode 33 and held at -¢ volt, a period elapses before the voltage on capacitor 84 is sufficiently low to cause bi-stable 72 to be reset via circuit 82 and cause bi-stable 41 to be responsive to the next trigger pulse. This produces a plateau 17 on the waveform 16. The charging current for capacitor 19 is determined by resistor 18 and the voltage at wiper 71 of a potentiometer 69 included in a constant voltage circuit of the bootstrap circuit. Resistor 18 and capacitors 19, 84 may be preferred values switched into and out of circuit.

Title: Monitoring of gyroscope rotor rotation

Abstract: 1308205 Gyroscopic apparatus ELLIOT BROS (LONDON) Ltd 19 July 1971 [21 July 1970] 35254/70 Heading G1C [Also in Division G4 and H3] To monitor the rotation of a gyroscopic rotor, the electrically-driven rotor 10 has a band 15 which is reflective except for two matt sections. Collimated light from a lamp 20 is reflected by the band on to a photo-detector 25 except when the matt sections cross the light path thus producing, for every rotor revolution in the correct sense, a cycle constituted by a long pulse (90 degrees) followed by a short interval (45 degrees) followed by a short pulse (10 degrees) followed by a long interval (215 degrees). This pulse train is amplified and inverted by circuit 31 to produce an output V 1 . Output V 1  is fed both to a differentiating, inverting and squaring pulse forming circuit 32 providing a pulse train V 4 , and also to integrating and squaring circuits 33 and 34 to produce a pulse train V 3 . Gate circuit 35 acts as an inverting coincidence gate producing a constant frequency positive output pulse train V 5  on line 36 only when the voltage outputs V 3  and V 4  are both zero, which only occurs when the rotor is rotating in the correct sense and its rotation axis has not precessed more than  0À05 degrees from it correct orientation. If the rotor is stationary or precession causes a collimating slit 24, carried on arm 17 of gimbal shaft 11, to cut off light to detector 25, no pulse train V 1  but unvarying signal, is produced, and if the rotor rotates in the opposite sense producing a short pulse followed after a short interval by a long pulse then the circuitry 30-35 will produce no output waveform V 5 .

Abstract: 1315071 Seaming non-metallic sheet material L R JOHNSON 23 April 1971 11038/71 Heading B5K Apparatus for positioning carpet seaming tape beneath two carpet pieces to be seamed comprises a base 11 slidable along a carpet seaming surface and supporting a roll 48 of carpet seaming tape 62 above two pieces of carpet 76 with their edges 75 abutting; a prow 74 at the leading edge of the base 11 for sliding beneath the abutting edges 75 and spreading them apart a distance less than the width of the tape 62; means 72, 79 above the prow 74 for longitudinally folding tape 62 withdrawn from the roll 48 and inserting the folded tape between the spread apart edges 75; and means 80, 82, 84 for unfolding and flattening the folded tape 62 beneath the edges 75, whereby the tape and the carpet are in position for the carpet to be seamed by being subsequently adhered to the tape. In one embodiment, Figs. 1, 3 and 4, an adhesive receptacle 12 is mounted on the base 11 and has a handle 26 attached thereto. The tape roll 48 is supported between two brackets 42. Tape 62 from the roll 48 passes between a wall 16 of the receptacle 12 and a bar 58. The receptacle 12 and the roll 48 are pivotable about a bolt 68 to facilitate the initial threading- through of the tape 62. The prow 74 is formed by the exterior surfaces 73 of two curved guides 72. The tape 62 is folded along a line 77 by the guides 72 pinching the tape and folding it about a fin 79. The flattening means comprises a flange 80 on each side of the bottom of the fin 79 widening at 82 into a plate 84. A conduit 90 conveys adhesive from the receptacle 12 to the tape 62 below the plate 84. Adhesive flows from the conduit 90 into a well 92 having a roller 102 disposed transversely thereacross. The roller 102 comprises two conical halves 108 joined at their bases which each have an annular ring 110 disposed therearound. The underside of the carpet pieces is coated with adhesive by the conical surfaces and the edges 75 are coated by surfaces 114 of the rings 110. Flow of adhesive through the conduit 90 is regulated by a valve 116 comprising a sealing member 118. To lift the member 118, a fingerpiece 148 is pulled rearwardly to rotate a trigger 142 in the direction of arrow 150 about a bolt 144 and rotate bellcranks 122 about a bolt 126. When the level of adhesive is substantially lower than a weir 154, the fingerpiece 148 is pulled rearwardly to permit adhesive to flow into the well 92 and, when adhesive flows over the 154 into a trough 152, the fingerpiece 148 is released. In another embodiment, Fig. 5, a roll 248 of seaming tape is supported in a curved trough 244 in front of the adhesive receptacle 212. The flow of adhesive through the conduit 290 is regulated by a valve 316 having a trigger 318 the bottom 320 of which is normally urged against the end of the conduit 290 by a spring 322. Reference has been directed by the Comptroller to Specification 1,192,259.

Abstract: 1334225 Rotary vacuum pump EDWARDS HIGH VACUUM INTERNATIONAL Ltd 9 Dec 1970 [16 Dec 1969] 61344/69 Heading F1F A mechanical oil-sealed vacuum pump having an oilway extending from a sump to an antisuckback system has an orifice or conduit preventing ingress of air during pump operation but admitting air to at least part of the oilway when the pump stops. A main pump 3 driven from a pulley 2 has an exhaust valve 23 in a well 19 while an oil pump 7 delivers oil from a sump 10 to a distributor valve 12 having a block 14 overlain by a seal 15. A smaller conduit 20 leads from the duct 11 to open above a well 18 while a duct 17 leads from an annular chamber 16 to the pump 3. In operation oil from the duct 11 raises the seal 15 so that it can flow from a chamber 25 to the chamber 16 and thus lubricate and seal the pump 3 while the conduit 20 delivers to the well 18. When the pump is stopped if the seal 15 fails to function once the well 18 and the conduits above the junction of 11 and 20 have emptied air will be drawn into pump 3 through the conduit 20 rather than oil from the sump 10. To prevent oil being drawn from the sump 10 along the driveshaft 1 two seals 5, 6 are provided with an interposed chamber 22 connected by a duct 21 to the well 18. If the seal 6 fails once the well 18 has emptied air will be drawn into the pump 3 while if 5 and 6 fail a similar effect will occur due to the greater resistance to the oil path along the shaft 1 and duct 9 to the sump 10.
