Abstract: 432,288. Gun turrets; wind motors. BOULTON & PAUL, Ltd., Riverside Works, NORTH, J. D., Hill House, Eaton, HUGHES, H. A., Westfield, Plumstead Road, and DOE, A., St. Peter's, Earlham Green Lane, all in Norwich. Feb. 13, 1934, No. 4741. [Class 92 (i)] [See also Group XXVI] Relates to power-operated means for rotating gun turrets, particularly on aircraft, in which a driving shaft 13, geared to a winddriven motor 18 deriving energy from the slip stream of the aircraft, operates a shaft 11, fast with the turret 10, through the medium of a friction clutch. According to the invention, the clutch comprises a friction disc 25 on the turret and a sliding shaft 23 which is geared to the driving shaft 13 and carries a friction wheel 27, the radial sliding of the shaft 23 causing the friction wheel to be engaged with or disengaged from the friction disc. In the arrangement shown, two friction wheels 26, 27 are provided on the shaft 23 to engage alternatively with opposite sides of the disc 25 to cause rotation of the turret in either direction.

Abstract: 435,185. Training-gear for guns and the like. BOULTON & PAUL, Ltd., Riverside Works, NORTH, J. D., Hill House, Eaton, HUGHES, H. A., Westfield, Plumstead Road, and DOE, A., St. Peter's, Earlham Green Lane, all in Norwich. Feb. 13, 1934, No. 4743. [Class 92 (i)] Relates to power means for training guns and other similarly mounted objects particularly on aircraft of the kind in which the gun &c. 13 is mounted on a pivot 15 on a U-shaped elevating arm 11 for limited manual training movement at the limits of which the means controlling the training motor are operated to effect movement of the gun support in the appropriate direction and at a speed corresponding to the extent of manual displacement of the gun &c. According to the invention, the motor-controlling means operated by a member 16 on the gun &c. are in the form of spring- loaded plungers 18 located on the elevating arm and connected to throttle valves 29 which control the passage of pressure fluid to the motor 35, Fig. 3. The direction of rotation of the motor is dependent on which of the plungers has been displaced, and the speed of training is proportional to the amount of opening of the valves. In the example shown, a rod 23 connected to the plungers carries a piston valve 29 controlling a triangular port 27 which admits fluid from a pipe 30 through a passage 32 in the rod and thence to the motor 35 by way of a pipe 34. Screws 25 allow for the adjustment of the extent of the manual movement. Specification 426,288, [Group XXVI], is referred to.

Abstract: 1486883 Injection moulding control SAABSCANIA AB 10 Feb 1976 [18 Feb 1975] 05230/76 Heading B5A [Also in Division G3] In a plastics injection moulding machine a sequentially operating system compares the actual temperature of the plastics (at 22) and the moulding pressure (at 23) at prescribed time intervals throughout the cycle with respective reference values and tolerances, produces an electrically readable statement as to whether or not any of the parameters are outside their tolerance, and issues an instruction for taking corrective measures which may be manual or autoteatic. The object is to ensure that the pressure/ time curve has a specific shape (Fig. 1, not shown). The complete sequence is as follows: (a) temperature, (b) mould filling time, i.e. time to reach set peak pressure, (c) to (e) the back pressure at times T2 to T4, measured from the end of (b). In each case the parameter error is obtained in comparators 19 ... 21 and is compared at 26 with the appropriate tolerance issued from 25. The result is resolved into a binary word, Fig. 3, each pair of terms represented whether a parameter is above, below, or within the tolerance band of its set value. This is converted into a corrective instruction, using a memory 31, to operate temperature, pressure, and ram motor regulators 14, 15, 12 and/or give an operator indication. None of the circuits are described.

A large part of the oil is collected in an annular groove a and is thrown out through a hole or holes b. In the arrangement shown in Fig. 2, the oil is supplied to a cup c separated from the shaft by a lip g, and passes to the bearing through one or more channels d which lead to grooves e in the bearing. The grooves e end in holes b through which surplus oil passes out. As shown in Fig. 3, oil supplied to a cup c passes to the bearing through holes d and is carried up by a groove on the shaft. The main part of the oil is collected in an annular groove a and is thrown out through holes b. Straight or spiral grooves may be formed on that part of the bearing surface which is not exposed to the excessive oil supply in order to collect and lead awav surplus oil. The invention is particularly applicable to the neck bearing of a centrifugal separator wherein oil is splashed up from a bath by a worm wheel.

In the embodiments described, the chamber is cylindrical, the gas is directed in tangentially and the charged conductor is either along the cylinder axis or mounted across one of the outlets. As shown, the gas is directed into chamber 1 at inlets 4, passes round passage 5 between the chamber wall and the inner wall 11 and reaches the inner chamber through slots 12. Gas also enters the inner chamber through the porous wall 14 thereby preventing the deposition of the decay products of the gas in the inner chamber or end wall.
