Abstract: 1431757 Agitating apparatus DERRITRON ELECTRONICS LTD 14 June 1973 [15 June 1972] 28027/72 Heading B1C [Also in Division F2] An electromagnetic vibrator 12 is mounted so as to be capable of vibrating a load at any angle between the horizontal and the vertical the mounting comprising a base 10, an unsprung support 17 mounted (by horizontal trunnions, not shown) on the base so as to be adjustable through at least 90‹ about a horizontal axis, a sprung support 40, to which the vibrator is attached, mounted on the unsprung support 17 by guiding means (rods 26, 27 sliding in bearings 22-25 in bosses 18-21 fast with the unsprung support 17) so as to be constrained to move relatively to it along an axis of vibration perpendicular to the abovementioned horizontal axis, and at least one pair of oppositely acting springs 29, 30 mounting the sprung support 40 on the unsprung support 17, the bias afforded by each spring being individually adjustable. The springs are air bags, two at each side of the vibrator, supplied from pneumatic reservoirs housed in beams 11 connecting end frames 10. When the vibrator is effecting vertical vibrations, the lower bags 32 are inflated, and the upper bags 31 kept at atmospheric pressure. When the vibrator has been rotated to effect horizontal vibrations, all springs are inflated to the same pressure.

Abstract: 390,818. Telephone and like transmission measurements. STANDARD TELEPHONES & CABLES, Ltd., MONTGOMERY, A. W., and TERRY, V. J.; Connaught House, Aldwych, London. Oct. 9, 1931, No. 28041. [Class 37.] A device for indicating and measuring the distortion of telegraph signals or the like comprises means 14, 15, 16 for converting signals of both polarities into inidirectional impulses and means 21, 22 for impressing the latter on a cathode ray tube 1 whose time scale is produced by a standard comparison frequency. The time scale of the tube is elliptical or circular and is produced by an oscillator 13, whose frequency is proportional to that of the signals, and a phase splitter 10, 12, the potential between the anode 3 and cathode 2 of the tube being normally such that the beam is just on the threshold of visibility on a scale 6 in the tube. Signals passing through a coil 14 operate a measuring relay 15 the contact arm 16 of which is connected symmetrically between condensers 17, 18, each of which, according to the position of the arm 16, is charged or discharged from a battery 19, protective lamps 20 being provided and coupling coils 21 being arranged to transmit unidirectional impulses to a coil 22 in series with a battery 26 across an adjustable resistance 23 which is connected across the anode and cathode of the tube 1. For each current impulse a cathodic beam is discharged on the scale 6, the position of this spot on the scale giving an indication of the distortion of the signals under measurement. Alternatively, the relay 15, 16, Fig. 2, gives alternating pulses to a transformer 24 which pulses pass through a network 25 of rectifiers and feed unidirectional pulses to a transformer 22. The oscillator 13 may be a valve oscillator driven by a tuning fork and can also be an ordinary Creed type morse transmitter and oscillator.

Abstract: 1,080,504. Clogging indicator for vacuum cleaner filter bag. ELECTROLUX Ltd. July 6, 1965 [July 17, 1964], No. 28560/65. Heading BIT. In a vacuum cleaner in which a diaphragm 22 is exposed on one side 24 to the pressure upstream of a paper filter bag 14a and on the other side 23 to a spring 37 and the pressure on the downstream side of the supporting bag 14, the diaphragm is normally held against a seat 36 which is adjustable so as to vary the pressure difference at which the diaphragm separates from the seat 36 thereby actuating a clogging alarm. Seat 36 is formed at the end of a channel 32 opening to the atmosphere and containing a metal reed 34, and when diaphragm 22 is displaced rightwards air is drawn through channels 32, 33 to the upstream, inside region of bag 14a whereby reed 34 gives an accoustic signal. Valve body 29, comprising channel 32 and seat 36, is threadedly adjustable in end cover 12 of the cleaner, displacing the diaphragm and compressing spring 37. The initial compression of spring 37 is adjustable by screw 38 which carries a further screw 39, and, if body 29 is sufficiently advanced, the diaphragm is clamped between screw 39 and seat 36 and the alarm is thereby inactivated. The diaphragm could move an external coloured indicator or open a switch to stop the motor.

Pre-firing may be carried out at e.g. 600 C. in a fluidized bed. The body may be formed by compressing granules obtained by spray-drying an acetone suspension of pre-fired powder, or by punching a dried sheet made by casting on to a substrate a mixture of preferred powder with a binder. Acetone or binder may be removed by heating to 300 C.

Title: Improvements in calculating apparatus

Abstract: 427,117. Calculating - apparatus. BYGRAVE, L. C., Royal Aircraft Establishment, Farnborough, Hampshire. Oct. 18, 1933, No. 28802. [Class 106 (i)] A calculating-apparatus for solving vector triangles, particularly those occurring in aircraft navigation, comprises a rotatable plate supported on a frame and having a radially and circumferentially adjustable pivot pin, a second pivot pin at a variable distance from the former pin, means for joining the two pins by a straight line and for indicating the bearing of this line against the edge of the plate. The frame 5 is slidably mounted on a base 6 to which is pivoted at 20 a slotted arm 19. The frame 5 carries a plate comprising a rotatable scale 1 and a rotatable disc 2 having a slot 16 through which projects a pin 9 engaging the arm 19. The pin 9 is mounted on a spring 10, Fig. 6, carried on a slide 11 slidable on the disc 2 and connected to a spring-pressed bolt which normally locks the scale 1 to the disc 2 but which is released when the pin 9 is moved to the extreme outer end of the slot. When the pin 9 is depressed, a projection 17 on the blade 10 is disengaged from teeth 18 on the underside of the disc 2 so that the pin 9 and slide 11 can move radially relatively to the disc 2. A toothed quadrant 23, Fig. 3, is connected through the pivot 20 with the arm 19 and engages a long pinion 24. A second quadrant 25 also engages the pinion 24 and is attached to an arm 22, Fig. 1. This arm thus remains parallel to the arm 19 and indicates the direction of the arm 19 on the scale 1. In use, the pin 9 is moved to the centre of the disc 2, thus locking it to the scale 1, and the frame 5 is moved until the distance between the centre of the disc 2 and the pivot 20 is equal to the air speed. The pin 9 is then moved to the outer end of the slot 16 to release the locking between the scale 1 and the disc 2, the zero of the scale 1 is set to a mark 29 and the disc 2 is turned until the slot 16 is in the direction of the wind, e.g. 270‹, on scale 1. The wind speed is set by the position of the pin 9 in the slot 16 and the line 9-20 then represents the ground velocity. The direction of this line is given by the arm 22 on the scale 1 and the drift by the same arm on a fixed scale 30. A circular slide rule for calculating speeds &c. may be mounted on the back of the device.

Abstract: 886,999. Piles; boring earth &c. COELUS, G. J. Aug. 19, 1960 [Aug. 21, 1959; March 1, 1960], No. 28841/60. Classes 68(2) and 85. A concrete pile is formed by a drill tube 1 with a screw-shaped bit 2 having a movable valve 4 which is closed during the downward movement of the drill, concrete being forced therethrough during the upward movement. Working via position A (Fig. 1) the bit is screwed into solid ground 3 (position B). During upward movement to position C the valve 4 opens and concrete from the tube 1 is forced therethrough. Subsequent screwing downwardly closes the valve again and the concrete is forced away to form an enlarged foot 5, as at D. Further enlargements may be formed above the foot as at E. With the pile thus cast up to ground level a reinforcement 7 may be lowered along guide means 6 (see F). The tube 1 continues into the bit 2 (Fig. 4), the valve portion 28 of which is fixed to a stem 23 having a screw 27 in a threaded casing 24 supported by members 25. A lug 26 on the valve stem 23 extends beyond the screw thread 22 of the bit offers resistance to the ground and according as the bit is screwed upwardly or downwardly controls the opening and closing of the valve. The drilling rig (Fig. 2) comprises a winch 9 for a cable 10 secured to a gear case 14 on the drill tube 1, which gear case is secured against rotation while being movable up and down in a shaft 17. The gear case contains a motor-driven worm-wheel mechanism. The motor and the winch 9 may be so controlled that the screw bit 2 will move up and down in the ground in accordance with the pitch of its thread.
