Title: Method of producing a fibrous tobacco material for cigarettes
IPC: A24B15/24
Filed: 1959-06-30
Abstract: Fibrous tobacco material is produced by grinding tobacco to a fine powder or extracting the aromatic ingredients therefrom, producing a spinnable mass by mixing the powder or extract with a spinnable and slow burning binder e.g. "Tylose" (Registered Trade Mark), and spraying the mass upon an endless belt to form threads having a cross-sectional size equal to that of natural tobacco fibres, the belt having a thin coating of tobacco powder previously applied thereon to prevent the threads adhering thereto.  The belt is preferably downwardly inclined so that the powder remaining thereon after the threads have been removed slides off automatically.  The threads, which are initially of round section, are coated from above by tobacco powder and flattened on the belt, while still plastic, by rollers to the width of natural fibres.  After removal, the fibres are cut to the normal length of natural tobacco fibres.  The tobacco powder applied to the belt and to the fibres may be of the same composition as the tobacco forming the fibres or may be of a higher grade.  The belt may be given rapid transverse movements to produce crinkled fibres and the solidifiication of the threads may be quickened by heating.

Title: Devices particularly applicable to internal combustion engine poppet valves for effecting relative rotation between two axially-loaded parts
IPC: F01L1/32
Filed: 1955-08-04
Abstract: 794,049. Valve gear. THOMPSON PRODUCTS, Inc. Aug. 4, 1955 [Aug. 4, 1954], No. 22451/55. Class 7(6) [Also in Groups-XXIV and XXIX] A poppet valve is rotated a small amount, when lifted from its seat, by the tilting of a coiled spring 30, backward rotation of the valve when it closes being prevented by a friction device 27. The lower end of a valve loading spring 39 engages a collar 51 rotatably mounted on a second collar 54, a frusto - conical washer spring 27 normally being in frictional engagement at its inner and outer edges, with the parts 51, 54 to prevent rotation therebetween. The coiled spring 30 has its coils almost vertical when the valve is seated but when the valve is lifted, the coil 30 first depresses the spring 27 to move it out of contact with the collar 51 thereby freeing the latter and hence the valve 36, for rotation relative to the collar 54, and then, under the axial force, the coils of the spring 30 tilt sideways causing a slight rotation of the plate 51 relative to the collar 54. Due to the tilting, the depth of coil 30 is reduced and the spring 27 returns into frictional engagement with the plate 51 at 58, preventing any further rotation. When the valve is seated and the axial load is removed from the springs 30, 27, the coils of the spring 30 return to their normal position without causing any backward rotation.

Abstract: 1334168 Dip-moulding; stripping BAXTER LABORATORIES Inc 19 April 1971 [26 Feb 1970] 22465/71 Heading B5A A machine for stripping flexible products, e.g. gloves 115, from dip-moulds 111 attached to a continuously moving conveyer comprises an array 109 of pairs of arms 110, means for moving the array parallel to, and at the same speed as, the conveyer, with each arm pair centered over a mould, means for sequentially moving the array towards the moulds, clamping the pairs of arms on to respective moulds whereby the products are gripped thereby, spreading the arms of each pair and then moving the array away from the moulds to strip the products. Each arm of a pair has fingers 113a, 113b for clamping on to a glove cuff, and when the arms of a pair are brought by means 133 into engagement with the product the fingers are brought together to clamp the cuff. The array is connected to a carriage 116 mounted on guide rods 117 and is lifted or lowered by a piston and cylinder 118, 119. The carriage is driven at the same speed as the conveyer by a chain and sprocket assembly 121, 122, 124, 125 in which dogs 127, 128 on drive chain 125 engage a catch on the carriage, and the latter is driven against the piston-rod 129 of a constant pressure air cylinder whereby when the carriage is disengaged it is returned to its original position. The carriage has trips for sequentially actuating microswitches controlling the stripping operation. The arm pairs act on alternate rows of moulds and the arrangement is such that on return of the carriage to its initial position the remaining moulds become aligned with the mould pairs. A horizontally reciprocable platform is brought below the array when the gloves have been removed from the moulds to receive the gloves from the fingers; the platform is then moved to a position above conveyers which receive the gloves when trap-doors on the platform are opened.

Title: Method for automatically maintaining an acceleration-controlled body in a desired attitude and apparatus for performance of the method
IPC: G05D3/16
Filed: 1966-05-20
Abstract: 1,146,023. Automatic attitude control. BOLKOW G.m.b.H. May 20, 1966 [May 28, 1965], No.22474/66. Heading G3R. In a system for automatically maintaining a body in a desired attitude, signals from a proportional rate of change of attitude detector are amplified and compared with step function signals generated by a change of attitude detector so that only differences exceeding a predetermined value cause attitude correction. As applied to an electrical system for maintaining the attitude of a satellite fixed relative to a star or the sun, one detector responds to angular deviations and produces a first signal which increases in steps with the deviation and another detector produces a second signal proportional to the rate of change of deviation. The second signal is suitably amplified and subtracted from the first. Whenever the difference exceeds a predetermined value a controller is operated to apply a torque of a fixed value in the appropriate sense to correct the attitude of the satellite. The effect of the number of steps in the first signal, the values of deviation at which they occur, and the amount of amplification of the second signal to produce a desired response are discussed in detail.
