Title: Improvements in or relating to methods of determining the out-of-balance of rotatingbodies in balancing machines
IPC: G01M1/22
Filed: 1926-08-03
Abstract: 256,277. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Aug. 3, 1925, [Convention date]. Testing balance of rotary apparatus. - Comprises a method in which the deflections of the rotating body are used to produce variations in the inductance or capacity in an electric oscillating circuit, so that the distance of the deflection caused by a marker in the record of an oscillograph from the deflection caused by the unbalance is used to determine the position of the unbalance. To determine the deflection of the rotary body a in the direction of the arrow b, a coil c is brought opposite to the periphery near this point. The coil together with a coil d and a condenser e form an oscillatory circuit of a valve transmitter. While the body is at rest, the anode current ammeter f is brought to zeroby a parallel arrangement including an electromotive force E and a resistance g. If now the body is rotated the deflections due to unbalance cause a periodic variation in the deflections of the ammeter owing to the varying air-gap between the body and the coil c. If now the measuring loop of an oscillograph be substituted for the ammeter, and a small marker comprising a piece of iron h be secured to the periphery of the body, the recording sheet of the oscillograph will be as represented in Fig. 2, and the distance " a " of the deflection caused bv the marker from that caused by the want of balance will give the position of the want of balance in the body. Instead of the coil c one plate of a condenser is substituted, the other plate being formed by the body a.

Title: Improvements in or relating to radio aerials
Inventor: MIDWINTER HENRY JOHN
IPC: H01Q19/30
Filed: 1958-06-17
Abstract: 926,171. Aerials. CHELTVIEW TELEVISION Ltd. June 18, 1959 [June 17, 1958], No. 19286/58. Class 40 (7). A radio aerial which can readily be designed to match a standard feeder cable of coaxial type comprises a dipole 2, 2 mounted centrally in a junction-box 5 and having attached to the outer ends of each of its elements matching bars 6 arranged symmetrically with respect to the dipole and angled inwards to meet at the point 7. The inclination of the bars 6 determines the impedance of the aerial. The aerial unit is used with a number of parasitic director elements 3 and a reflector 4. The spacing between the elements 2 and the nearest director 3 is made less than half the distance between the latter and the next director. In constructing the aerial, the lengths of the various elements and their spacings are first chosen to give maximum induced signal at the working frequency. Then the inclination of the bars 6 is chosen to match the aerial to its feeder. The correct angle of inclination can conveniently be found by experiment using a dipole assembly with pivotally connected matching bars of adjustable length. Instead of connecting the feeder to the dipole at the junction box 5 it is possible to connect the dipole elements together in this box and to connect the feeder to the ends of the matching bars. Where it is desired to receive a second (lower) frequency signal with the same aerial system, the element 4 is replaced by an element 8 (Fig. 3) resonant at the second frequency and having its limbs inclined so as to be substantially parallel to the bars 6. To provide an impedance correction offsetting the effect of the presence of the element 8 the ends of the matching bars are not directly connected but coupled through a capacitor mounted in insulating block 9. The gain at the lower frequency can be increased by the use of a reflector 10 if required.

Abstract: 861,850. Miniature track diagrams. LIEWALD, F. June 19, 1957, No. 19318/57. Drawings to Specification. Class 105. A miniature track diagram has the indications of the route set up, occupation by a train and the aspects of the wayside signals given by cathode-ray tubes having rectangular screen ends and arranged side-by-side, the indications being set up by appropriate voltages being applied to the horizontally and verticallydeflecting plates and to the grid of the tube. A sawtooth voltage applied to the horizontallydeflecting plates in conjunction with a rectangular form voltage on the grid gives a broken horizontal line indication; the sawtooth voltage gives a continuous line indication and an appropriate sinusoidal voltage on the vertically deflecting plates deflects the cathode-ray beam on to an appropriate area of the screen which fluoresces in a colour appropriate to the wayside signal aspect. A plurality of track and signal indications may be given in a single tube by rapid switching of deflection voltages and utilizing the persistence of vision.

Abstract: 150,881. Brondum, M. V. Aug. 6, 1919. Potato diggers and harvesters. - Relates to moving grates for separating earth from the potatoes in a potato harvester, of the type comprising serrated grate-bars having a circular or elliptic motion in the opposite direction to the rotation of the road wheels, adjacent bars rising alternately so as to move the potatoes along the grate. According to the invention the bars 21, 22, Fig. 1, are arranged in pairs, the bars of each pair working close together as shown in Fig. 4. In one form the grate-bars 21, 22 are carried at one end on a crank shaft 8 and at the other end on rollers 28 behind the share 5. Each bar may have a single crank, or alternate bars may be connected by transverse rods 24, 25 so as to move together. The crank-shaft 8 is mounted on arms 9 adjustable by means of struts 10 engaging a series of holes 12. The share is adjusted in height by means of a hand-lever 16 and links 19, 13. Certain of the bars 21, 22 are extended beyond the shaft 8 to carry the haulms rearwards, allowing the potatoes to fall through, and a grating adjustable to incline to either side may be arranged to receive them. The share 5 may be dispersed with and the ends of the bars 21, 22 constructed to act as diggers. Modified mechanisms for supporting and operating the bars 21, 22 are described. The rollers 28 may be replaced by a second crank-shaft geared to the shaft 8, or by a rocking double crank or disk from which the bars are suspended by pivoted or spring hangers. Similar motion may be obtained by means of levers connected to the crank shaft 8 and supported centrally by a link or spring from the frame, and having a slotted connexion at the forward end with similar centrally supported levers connected to the front end of the bars 21, 22. A pair of rocking double-cranks or disks 49, Fig. 7, may be used, operated from an elevated crank shaft 52, connecting-rods 55, 56 being employed to give the horizontal motion to the bars 21, 22. The share and bars are both carried by the same frame so that both are moved by the share-adjusting hand-lever. The spring rods 41, 42 rigidly fixed to the bars 21, 22 assist in checking the momentum of the bars. The rear suspension 49, 41, 42 may be replaced by rigid brackets extending down from the centre of the rods 55, 56. This construction may be employed also where the roller support 28, Fig. 1, is used at the front. One end of the bars 21, 22 may be supported from a crank-shaft 81, Fig. 11, by rods 79, 80 linked at the centre to a fixed point 88, the other end being supported on hangers 82, 83 either from an extension of the links 84, 85, from fixed brackets shown in dotted lines, or from a rocking double crank. If the rods 79, 80 are connected rigidly to the centre of the bars 21, 22 no other support is required. The bars 21, 22 may be formed with a step. the rear part being at a lower level, and the lateral bars may be wider or mounted higher than the central bars to give the grates a trough-shaped upper surface.

Abstract: 746,148. Disc brakes. TRIGGS, W. W. (Yale & Towne Manufacturing Co.). July 5, 1954, No. 19631/54. Class 103 (1). [Also in Groups XXIV and XXX] In a hoist of the type in which a combined clutch and brake mechanism, i.e. a Weston brake, is provided to hold and control a load applied to the hoist, a ratchet disc, mounted for free rotation in the axis of the drive shaft and forming part of the clutch and brake mechanism, is formed with a series of ratchet teeth at one side thereof and projecting parallel to the axis of rotation and a pawl having a series of teeth is mounted in a direction parallel to the axis of rotation towards and away from the ratchet disc; spring means being provided through which the pawl is pressed bodily on its mounting means towards the ratchet disc to oppose rotation of the drive shaft in a load lowering direction by engagement of the pawl teeth with the ratchet teeth. In the embodiment illustrated in Fig. 1, the hoist chain 15 is reeved over the load sheave 13 which is driven by a drive shaft 14 fitted with a pinion 17 which meshes with a gear 16 splined on to the load sheave. The drive shaft 14 is operated by a hand wheel 18 rotatably engaged upon a screw threaded portion 19 of the drive shaft so as to control the latter through a combined clutch and brake mechanism 20. The combined clutch and brake mechanism 20 comprises a friction disc 21 mounted upon the threaded shaft portion 19, and a ratchet disc 22, provided with a friction ring 22a, confined between the handwheel 18 and the friction disc 21. When the handwheel 18 is shifted inwardly, by its rotation relatively to the threaded portion 19, the ratchet disc 22, friction disc 21, the handwheel 18 and the drive shaft 14 are secured for rotation as a unit, thus permitting a load upon the hoist chain 15 to be raised by clockwise rotation of the hand wheel 18. If the driving force of the hand wheel 18 is discontinued, the weight of the load on the chain 15 will tend to rotate the drive shaft 14 and the brake in a reverse direction to lower the load. This tendency is prevented by a pawl 25 provided with inclined teeth 27 being spring urged by coil springs 28 into engagement with a series of ratchet teeth 24 formed on a continuous cylindrical flange 23 of the ratchet disc 22. A cushioned pressure ring 31 is provided between the handwheel 18 and the ratchet disc 22 to contribute also to uniform control and operation in order that there will be no eccentric forces upon the friction disc 21. The load is permitted to descend by a slipping action of the combined brake and clutch mechanism to an extent corresponding to the rotation of the hand wheel 18.
