IPC: B65G23/14
Filed: 1957-10-10
Abstract: 834,607. Endless bucket conveyers. HAPMAN, H. J., and HUFFAKER, M. S. Oct. 10, 1957, No. 31665/57. Class 78 (1). A bucket conveyer, of the type having buckets which are mounted for swinging on axles extending between a pair of endless chains, is driven by a series of driving abutments 70 extending transversely of and secured to a pair of endless driving chains 58 arranged above the path of the buckets, the abutments 70 being caused to move in a sagging path so as to move gradually into and out of engagement with the buckets. In one embodiment, Figs. 1 and 4, the buckets 14 are adapted to carry loose material and consist of pans 15 having end walls 16 which are provided on their outer faces with ribs 17 for engagement by dumping apparatus (see below). A sleeve 18 extends between the end walls 16 for reception of axles 20 extending between a pair of endless chains composed of outer and inner links 22, 23. The axles 20 are extended beyond the conveyer chains and carry rollers 24 engaging U-shaped tracks 26. The abutments 70 engage the sleeves 18 to drive the conveyer. Two series of rollers 129 are positioned to engage the lower runs of the two driving chains 58 and hold the latter in their sagging paths where they engage the buckets. Two further series of rollers 104 freely rotatable on axles 102 engage the upper runs of chains 58 and maintain the latter in straight paths. The chains 58 are carried by sprockets 54, 56, the former being driven by a motor 92 via a gear-box 80, and the latter being adjustably mounted for tensioning the chains 58. In a second embodiment, Fig. 5, the buckets 170 are driven on an inclined portion of their path and the driving chains 58 are similarly inclined but are otherwise supported and guided exactly as in the first embodiment. In order to prevent the buckets from fouling the chains 58 they are provided with flanges 198 which engage a series of rollers 208 so as to forcibly tilt the buckets into line with their direction of movement. The buckets are divided into two compartments by partitions 186 so that each can carry two metal pegs. These are discharged by dumping apparatus consisting of two pairs of pegs 172, 174, the pegs forming each pair being carried on opposite sides of the conveyer guide framework. The first pair of pegs 172 engages ribs 176 formed on the ends of the buckets to partially tip the buckets, while the second pair of pegs engages the flanges 198 to complete the tipping of the buckets. As in the previous embodiment, sleeves 190 extend between the ends of the buckets and receive the swing axles 184 which are carried by endless chains composed of outer and inner links 180, 182. The axles are extended beyond the conveyer chains to carry rollers 210 engaging U- shaped tracks 143. At the upper reversal point of the elevator the upper and lower runs of these tracks are joined by arcuate track sections 144, while at the lower reversal point tensioning sprockets are provided (Fig. 7, not shown).

Title: An aircraft alam providing a tactile warning signal
Inventor: GREENE LEONARD MICHAEL
IPC: B64C13/42
Filed: 1960-09-19
Abstract: 890,248. Stall warning indicators on aircraft. SAFE FLIGHT INSTRUMENT CORPORATION. Sept. 19, 1960, No. 32157/60. Class 4. An aircraft alarm adapted to be secured to an inanimate object in an aircraft for providing a tactile warning signal comprises a weight, means mounting said weight for rotation about an axis spaced from the centre of gravity of the weight, means to spin said weight rapidly about said axis so as to create a shaking action, and means for securing said mounting means to said object for limited movement relative to said object in a direction generally transverse to said axis of rotation between limits defined by abutment of said mounting means and said object or an attachment thereon so as to partially convert said shaking action into a series of sharp raps that are distinguishable from aerodynamic buffeting of the aircraft. The alarm, which is mounted on a control column 10 to give a warning of impending stall conditions, comprises a housing 16 formed with an inner sleeve 14 to form an annular cavity within which is mounted a bearing 20 supporting a gear ring 22 to which an eccentric weight 24 is attached. The gear ring 22 is driven through pinion 24<SP>1</SP> by an electric motor 28 which is energised through a circuit 54, 56, when a stall-detecting device on the aircraft closes a switch 58. The housing 16 is attached to the control column 10 by a mounting 32 comprising a split clamp having leaf springs 42, 44 respectively riveted thereto and secured at their upper ends to lands formed on diametrally opposed inner faces of a sleeve 40 secured to housing 16 by a base flange 42<SP>1</SP>. In operation, with motor 28 running, the rotating eccentric weight 24 will cause housing 16 to oscillate laterally on leaf springs 42, 44 to an extent that causes projections 50 to hammer against a protective sleeve 52 on the column, thus producing a tactile warning signal that is readily distinguishable from stick vibration resulting from aerodynamic buffeting of the aircraft. A further embodiment is described in which a vibrating unit is mounted offset from the axis of the control column by a bracket carrying a single leaf spring, Figs. 5 and 6. (not shown), and in another embodiment, Fig. 5 (not shown), a housing such as 16, Fig. 2, surrounds the control column with a clearance and is formed with a depending portion pivotally mounted by a bolt passing diametrally through the column so that the housing may rock laterally. Specifications 660,854 and 668,805 are referred to.

A coaxial attenuation unit operative from direct current to frequencies of about 10 kilomegacycles comprises a shunt resistor having a film of resistance material on the conical or approximately conical outer surface of a homogeneous low-loss dielectric core, coaxially arranged in the unit to constitute a shunting impedance and progressively intercept signal energy with a relatively low V.S.W.R. over a wide frequency range. A.T. pad attenuator unit 20 is arranged between the terminals 21, 31 and 22, 32 of coaxial lines and comprises a metallic shielding member 23, a resilient shim 39, and tapered cylinders 40, 41 interconnecting outer terminals 21, 22. Two cone-like members 37, 38 of steatite or other low-loss dielectric material carry a film of carbon on their surfaces 58, 59 and form a resistor element 35 having a conductive ridge 36 locked in position between cylinders 40, 41. The silver-surfaced hollow interior 43 of element 35 is connected by clips 46, 47 to series resistors 50, 51, the opposite ends of which are connected by clips 56, 57 to conductors 31, 32. Alternatively, the faces of each conical element may be curved exponentially, or the resistor surface of the conical element may be inclined to the direction of incident power at such an angle as to create total internal reflection so that the power is all developed across the film. The invention may be applied to TT-pads, L-pads or terminations.
