Abstract: 1461153 Reversing sprinkler devices G H LOCKWOOD 12 Sept 1974 [12 Nov 1973] 39835/74 Heading B2F A sprinkler device 2 comprises a sprinkler body 6 rotatable relative to a base 4, which receives fluid e.g. water, and having a nozzle 8, a drive including a drive arm 10 for oscillating the sprinkler nozzle over a predetermined adjustable curved path and a clutch connected to the sprinkler nozzle to permit the nozzle to move outside the predetermined path if accidentally knocked, the clutch and the drive, connected to the sprinkler body, moving the nozzle back into the predetermined path. The clutch has parts 24, 28 which engage each other only when the nozzle moves in the predetermined path, the clutch being connected between the base 4 and a dog drum 20 which are urged together by a spring 26. The dog drum is rotatably mounted on the base 4 and carries dogs 16, 18, the angular space between them being adjustable to preset the arcuate path-length of movement of the body 6. The reversing dogs are contacted alternately by a reversing lever 14 which operates a reversing mechanism 12 of the drive. The torque required to disengage clutch tooth 24 from notch 28 is greater than the torque required to move the reversing lever 14 to actuate the reversing mechanism 12 to reverse the direction of rotation of the nozzle. Thus the preset position of the reversing dog 16, 18 is maintained when an external force which disengages the dog drum is removed since the sprinkler body rotates until tooth 24 engages notch 28 and the preset path is restored. The sprinkler may be a ball-driven or a turbine sprinkler.

The head 16 carries a fibre optic bundle 36 in a recess 254, Fig. 11, of an arcuate document contacting surface 202 of the head which maintains the exposed fibre optic ends 250 at the predetermined distance from the document mounted on the drum. The bundle comprises at least one light receiving fibre and at least one light emitting fibre so that it may simultaneously illuminate and read the original document carried by the drum. The head 16, Fig. 1, is mounted on a drive shaft 20 disposed parallel to the axis of rotation of drum 12 and moved therealong by the interaction of skewed rollers 215, Fig. 9, mounted on the head, and carries a control shaft 212. A cam 210 is mounted on the control shaft 212 so that when turning the latter about its axis the cam 210 disengages the head biasing spring 208 from the underside of a housing cover part 214 and releases the rollers 215 from engagement with shaft 20 by overcoming resilience of roller retaining spring washers 222, enabling the head to be moved freely and axially along shaft 20. The control shaft 212 has an actuating knob 118 at its forward end and this knob has integrally mounted theron a cutting wheel 64, Fig. 11, and a soft roller 116 so that by turning the knob 118 in one direction the document may be cut and by turning the knob in the opposite direction the head position may be freely adjusted along the drum. To facilitate cutting, axial grooves (120), Fig. 4 (not shown), may be provided on the curved surface of the drum. A second cam 236, Fig. 9, is provided on the rear end of the control shaft 212 which, when knob 118 is turned, actuates a micro switch 230 which interrupts the power supply to a stylus 38 mounted on the head adjacent the fibre optic end. The stylus 38 extends into contact with an electronsensitive record medium carried by the drum when the device is used in the receiving mode. The head 16 further comprises a lamp 258, Fig. 8, for supplying light to the illuminating fibres (302, Fig. 14, not shown). An infra-red filter may also be used to facilitate the detection of blue ball-point pen ink.

Abstract: 1,109,602. Spectrometer. ALBRIGHT & WILSON (MGF) Ltd. Oct. 21, 1964 [Oct. 21, 1963; Jan. 6, 1964; March 6, 1964; Oct. 5, 1964], Nos. 41456/63; 576/64; March 6, 1964 and Oct. 5, 1964. Heading G1A. [Also in Division G2] A stream of gas such as argon, helium, nitrogen or oxygen, is passed at 2 tangentially into a tube 4 and a carbon rod is introduced into the open end of a vessel 1 surrounding the tube 4 so that the heating induced therein by high frequency current passing through a coil 3 causes heating of the gas surrounding the carbon rod to ionize it sufficiently to initiate a stable plasma which is of annular form and is maintained when the rod is withdrawn. Argon or other gas is fed into an injector inlet 8 and causes the powder sample being rotated in drum 11 by motor 13 to be drawn up the capillary tube 10 and sprayed through the low temperature central region of the plasma to form a tail flame at the open end of vessel 1 whose spectrum may be analyzed using a spectrometer. An insulating gas or liquid fed at 2 into vessel 1 surrounds the plasma. The high frequency current supplied to coil 3 may be modulated by using an oscillator whose power supply has inadequate smoothing, and a mechanical chopper is not essential then, when using photo-electric cells for detection, as an A. C. current is produced which facilitates amplification. Moreover with such modulation the temperature of the plasma varies cyclically at the modulation frequency and by using a particular part of each cycle to perform spectral measurements the sample temperature may be selected at any value desired within a range. Apparatus for doing this may comprise a cylinder 31, Fig. 3, rotated by an electric motor 32 in synchronism with the modulation frequency, and with a phase relationship thereto selected by rotation of the motor 32 as indicated by scale 34, the cylinder 31 being slotted at 33 so that radiation passes from tube 1 through broad-band optical filter 38 and narrow-band interference filter 39 to phototransistor 41 only once per cycle of modulation. In a modification a Kerr or Karolus cell is used as interruptor instead of a rotating cylinder.

The valve member has one end tapered so as to co-operate with an opening 78 of insert 56 whilst the other end is enlarged and fluted as at 70 such that when this enlarged end is engaged with insert 54, under the action of a spring 68, flow still takes place between the enlarged end and the inlet insert. Increasing of flow-rate causes the valve member to move against the spring bias and, in the extreme, to engage the outlet insert 56, such engagement being by way of projections 74 which prevent complete closure of the outlet opening 78. Accordingly the maximum flow-rate through the device is independent of the pressure differential thereacross.

In a push-pull amplifier, more especially for feeding a reactive load 7, the cathode of each output valve 1, 2 is returned to ground via an un-bypassed resistor 8, 9, respectively, and negative feedback is applied by means of a tertiary winding 13 on the output transformer 5, which is connected, in series with resistor 12 and D.C. blocking capacitor 14, between the cathodes. The output stage is driven by means of a pair of transistors 21, 22 each of which has an individual un-bypassed emitter resistor 25, 26, respectively, the two emitters being connected together by a resistor and D.C. blocking capacitor in series. The arrangement may be switched off, either by opening the positive supply to the screen-grids of the output valves 1, 2 by means of a switch 39, or alternatively by applying a positive pulse via terminal 36 and capacitor 37 to the base of an auxiliary transistor 30. The collector potential of this transistor then goes negative, biasing the output valves 1, 2 to cut-off. In addition, diode 29 common to the emitter circuits of transistors 21, 22 and which is normally conductive, is biased non- conductive, the biases on the transistors 21, 22 then becoming such that these transistors are also cut off.
