[Class 130.] To average the tobacco in a tobacco-feeding machine, the tobacco, after leaving the carding mechanism, is distributed by an arrangement of conveyer drums arranged in series. Tobacco fed by a belt 10 to a carding drum 13 is dressed by a drum 16 and removed by a picker roller 21 adjacent which is a comb. The tobacco removed by the picker roller is distributed in a housing having stages arranged one above another so as to reduce the door space. A roller 24 distributes the tobacco over a drum 27 from which it is removed by a picker roller 29, and projected on to a roller 24<a>, and the process is repeated until the tobacco is finally deposited on a web 31 of cigarette paper. The advancing faces of the vanes 136 of the rollers 24 are flat and radial while the rear faces 38 are arcuate. These rollers may also serve to winnow the tobacco so that dust and undesirable portions are rejected. In a modified construction, the tobacco is distributed on to the conveyer drums directly by the picker rollers, which perform the winnowing and distributing actions of the rollers 24.

Title: Pressure-modulation device for a hydraulic circuit
IPC: B60T8/50
Filed: 1974-05-20
Abstract: 1473674 Modulating valves SOC ANON FRANCAISE DU FERODO 20 May 1974 [24 May 1973] 22403/74 Headings F2F and F2V In a modulating valve assembly 15 a chamber 24, communicating with an hydraulic pressure producing device, is communicable with a chamber 26, communicating with an hydraulic pressure receiving device, via a normally closed pressure regulating valve member 29 controlling flow through a passage 28 and a normally open isolating valve member 41 controlling flow through a passage 37 axially within the member 29 which carries a guiding tail 32, in a bore 33 connected to the chamber 26, at its end remote from the member 29, the chamber 24 being substantially coaxial with and disposed between the chamber 26 and the bore 33, the member 41 being housed in a recess 38 integral with the member 29 and into which the passage 37 opens. Specification 1,473,583 claims a different aspect of the disclosed assembly. Fig. 2 indicates the modulating valve assembly allowing uninterrupted hydraulic flow from a master cylinder via a line 25, the chamber 24, the passage 37, the chamber 26, and a line 27, to wheel brake actuators. Upon receipt of a skid signal, an armature 51 moves rightwardly towards a yoke 49 to close an air gap 52, and in doing so, moves a needle closure member 63 and associated piston 60 to open communication between the chamber 26 and a line 72 via passages 47 and a chamber 70. The passages 47 produce a pressure difference between the chambers 26 and 70 causing leftward movement of a piston 45, allowing the valve member 41, e.g. a ball or disc, to close off the passage 37, pressure in the chamber 26 reducing due to flow in a line 72 leading to an accumulator chamber 73 bounded by a piston 79. This decrease occurs until a rod 62 is engaged by the piston 45 to close the line 72 by the member 63, against the armative force. Upon cessation of the skid signal, the armature 51 moves leftwardly, with consequential rightward movement of the piston 45 which contacts the closure member 41; however, the member 41 moves with the member 29 as a unit, opening communication between the chambers 24, 26 but via an orifice 31 and a chamber 24B, this action being controlled by a spring 80, acting on the guiding tail 32, in turn controlled by the piston 79 and the fluid in the accumulation chamber 73. This action continues until the member 41 opens up the passage 37. Fig. 10 shows the member 41 in the form of a disc surrounded by a perforated cage carrying the guiding tail.

Abstract: 943,376. Moulding plastic tubing. B. SEILER, and W. SCHLATTER. June 12, 1962 [June 13, 1961], No. 22571/62. Heading B5A. Successive sections of heated plastic tubing are subjected to vacuum moulding so as to form a series of hollow elements joined by narrow tubular sections, suitable for ampoules. In one example a thermoplastic tube 2 is heated to softening temperature in a heater unit 1, comprising a pre-heating chamber 4 and a main chamber 5, by means of blown hot air or heat radiation. The tube is advanced in steps by two endless belts 7, and as successive heated sections traverse a forming unit 9 jaws 10 close, recesses 11 gripping the tube and a vacuum is applied through bores 13, so that a hollow element 15 is formed. In a second example (Fig. 2a) the tube is held by four pairs of retaining jaws 20, 21, 22, 23 and heated by two pairs of heating jaws 17, 18. The retaining jaws advance the heated tube stepwise with the heating jaws open and vacuum moulding is carried out as described above. In a third example, Fig. 3 (not shown), an extrusion press produces the tubing already heated. With a press which produces successive sections of tubing by strokes of a plunger a forming unit as in Fig. 1a is employed. With a continuous extrusion press a similar arrangement is used, but the jaws 10 are arranged to traverse rectangular paths. When closed they move with the advancing tube at its own speed and then move quickly backwards when open. The jaws of the forming units may be cooled, and jaw recesses 11 may be smaller than the tube being formed.
