Title: Improvements in Mine Signalling Apparatus.
Inventor: MILLAR WILLIAM
IPC: B66B19/06
Filed: 1917-10-01
Abstract: 119,514. Millar, W., and Strachan, J. Oct. 1, 1917. Mine and colliery signals.-Signalling apparatus for use in mines &c. has two pointers, operated independently but by the same wire, &c., one registering signals complying with legal requirements, the other registering signals determined by the colliery &c. officials. Signals are cancelled on compliance by pneumatically operated mechanism worked by the winding engine. A spindle c, provided with a ratchet wheel operated by a pawl l on a sliding frame k reciprocated in the usual way, has a pin f<1> engaging a pin f<2> on a second ratchet wheel h carried by a loose sleeve d to which the indicating pointer e is attached. The ratchet wheels are respectively held by detents i<1>, i, the former being normally held out of engagement by a cord i<7> secured to the piston i<4> of a time-lag device, but lowered into engagement when a signalling impulse raises the frame k. After a pause, the spindle c returns to the zero position, the pointer remaining to register the signal until complied with, or until the first impulse of a succeeding signal which releases the detent i by means of a projeotion k<2> on the frame k. To prevent the pointer from moving more than one step at a time, a third ratchet wheel is provided with its teeth in the reverse direction and co-operating with a pawl u<2> carried by an arm u<1> loosely mounted on the sleeve d. Upward movement of the frame k releases the pawl u<2> by means of an arm u<5>, and the arm u<1> is moved over to the left by a weight u<7>, the pawl u<2> engaging the next tooth of its ratchet wheel. Descent of the frame k moves the ratchet wheel and with it the arm u<1> to the right. Movement of the arm u<1> is limited by stops u<6>. The second pointer v is operated by a ratchet wheel v<2>, and the centre on which the signalling lever (not shown) works can be raised or lowered so that the pawl l can be made to operate the lower or upper indicator at will. When the upper indicator is in use, audible signals are given in the usual way on a gong A, but when the frame k is lowered to operate the pointer v, the gong connexion is slack so that no audible signal is given. Both pointers are returned to zero by engineoperated means acting on the detents through levers r. The engine, when running, operates an air pump n so as to raise a weighted piston n<2>, thus causing a pivoted lever p' to depress one arm q of a T-shaped lever, the other arms of which are connected by means q<2> with the levers r When the engine stops, air escaping through an adjustable valve n<4> allows the piston n<2> to fall, the lever q being again operated to cancel any signal which may have been registered during the running of the engine. The lever p' is also connected by means s with a plate t, which is raised or lowered to exhibit the words " raise " or " stop " when the engine is stopped or running.

Filed: 1965-04-02
Abstract: 1,039,057. Retractable ball-point pens. G. LINZ. April 2, 1965 [April 4, 1964], No. 14128/65. Heading B6P. A sleeve 9 rests on a non-friction bearing 6 of the barrel 1 and below a similar bearing 3, to facilitate rotation, and is formed internally with two annuli of teeth 10, 11 angularly staggered with respect to each other, the annulus 11 comprising alternate deep and shallow teeth. A push-button actuating member 12 associated with the writing-element 19 is provided with cams 13, 14 and is prevented from rotating by a recess 17 co-operating with a rail 18 on the inside of the cap 2. The sleeve is of resilient deformable plastics material to allow the element 19 to be inserted therein so that the cams 13, 14 are brought into a position to co-operate with the annuli 10, 11. Depression and release of the push-button thus rotates the sleeve and brings the cam 14 alternately into the deep and shallow teeth, thus defining the retracted and projected positions of the point. Alternatively, the cams may be staggered and the teeth axially aligned.

Abstract: 1371372 Axial-flow fans ROLLS-ROYCE (1971) Ltd 8 May 1972 [6 May 1971] 14173/71 Heading F1C In variable pitch rotary blading including blades mounted on a rotor for rotation about their longitudinal axes to change their pitch, the pitchchanging mechanism comprises an actuator, a plurality of driving members each forming part of a first driving connection between the actuator and a respective one of the blades, and a plurality of driving elements each forming part of a second driving connection between the actuator and that blade in parallel with the first driving connection, the driving elements being adapted to allow deflection of the respective driving member whilst being capable of transmitting the torque required to vary the pitch. The ducted fan of a gas turbine engine comprises blades 2 which are varied in pitch by, e.g., a vane-type hydraulic actuator 40 acting through bevel gearing 48, 50, 52. Each bevel gear 52 is connected to the corresponding blade root 10 via a shaft 54 and a member 56 which is screw threaded into the blade root at 58, the shaft being secured to the,bevel gear by a nut 60. The bevel gear 52 is further connected to the blade root 5 via a hollow shaft 62 which is splined to the bevel gear at 66, splined to the member 56 at 64 and splined to a ring 32 at 34. The ring 32 forms the inner race of a bearing 30 and is splined to the outer race 22 of a bearing 24. A ring 28 screwed into a circular aperture in the outer wall 20 of the fan rotor forms an inner race for the bearing 24 and an outer race for the bearing 30. The outer race 22 is splined to the blade root 10 at 26. The shaft 54 is capable of bending and the hollow shaft 62 is capable of tilting at the same time, this movement being accommodated by the splines 34, 64 and 66. This permits movement of the bevel gear relative to the blade root 10 to accommodate any discrepancy between the mating of the bevel gears 48, 50 with any bevel gear 52 and to accommodate blade vibration.

Title: Improvements in or relating to electric oscillator circuits
IPC: H03K3/78
Filed: 1940-09-19
Abstract: 573,269. Valve generating circuits. SCOPHONY, Ltd., and DODINGTON, S. H. M. Sept. 19, 1940, No. 14344. [Class 40 (v)] In a generator, the oscillations produced are utilized to set up a train of mechanical oscillations of lower frequency in a liquid column which are connected to electric control oscillations and arranged to control the amplitude of the high-frequency oscillation. The Figure shows a blocking oscillator 1 ... 4, the output from which is applied to a piezo-electric crystal associated with a liquid column 7 terminated in a thick steel reflecting plate 8. In this way, energy reflected from the plate 8 may be arranged to trigger the circuit 1 ... 4 into oscillation after either one or more reflections. If the reflected waves are too weak to exert effective control, the plate may be replaced by a second piezo-electric crystal from which a feed may be taken back to the blocking oscillator through an amplifier, Fig. 2 (not shown). The control oscillations may be detected before being used to control the blocking oscillator. Specification 375,568 is referred to.

Title: Means and method for backwashing filter bed
IPC: B01D29/27
Filed: 1962-04-16
Abstract: 971,476. Filters for liquids. J. A. RICHARDS. April 16, 1962 [April 18, 1961], No. 14536/62. Heading BID. A filter system comprises a filter tank 29 incorporating a plurality of filter elements 74, a reversible pump having a tubular casing 10, a conduit 37 leading to the side of the pump which normally operates as the suction side from a source of liquid, a waste conduit 30 leading from this conduit, a conduit 36 leading from the side of the pump which normally operates as the pressure side to the tank, a conduit 38 leading from the tank to the source of liquid, and an isolating ball valve mechanism in a casing 21 adapted to close the waste conduit when the pump is drawing liquid from the source and for opening the waste conduit when the pump is reversed for drawing liquid from the tank. Normally, liquid passes through conduit 37, casing 21 containing a strainer basket, pump 10, filter tank 29, and conduit 38. When back-washing is required, the pump is reversed, flow being through conduit 38, tank 29, pump 10, casing 21, and waste conduit 30. A suitable automaticallyoperated valve for opening conduit 30 within casing 21 is described, Fig. 7 (not shown). To replace filtering material deposited on the filter members 74, a tank 57 containing a slurry of, for example, diatomaceous earth, is agitated by liquid injected through a jet tube 60 on opening of a valve 54 when normal flow is resumed. This raises an arm 82 and rod 63a to open a valve 63 and allow the pump to pass slurry to the filter until the level of slurry drops and valve 63 closes again. During this operation, a magnet 65 on rod 63a draws down an armature 66 releasing a catch 70 from drum 71, until the connection between magnet and armature is broken as rod 63a falls further. Drum 71 rotates under gravity to drop one load of pellets 72 of filter material. Valve 61 controlled by rod 82 restores the slurry level. This cycle of operations may be governed by cams driven by an electric motor, Fig. 8 (not shown), and initiated by hand, at a given time, or in response to pressure within the system. The pump 10 may be a multi-stage turbine.
