Title: Apparatus for stretching and smoothing a natural tobacco leaf
IPC: A24B5/14
Filed: 1969-08-26
Abstract: An apparatus for stretching and smoothing a natural tobacco leaf 3, e.g. prior to stripping, comprises an air permeable leaf supporting conveyer belt 1 and retaining members 8, 32 co-operating therewith to keep a narrow zone 35 of the leaf 3 fixed relative to the belt 1, air flow members 17, 18, 19, 33 disposed above the belt 1 to direct an air stream from the central vein of the leaf 3 towards its edges, and a suction device 7 disposed below the top run of the belt 1 to retain the leaf 3 on the belt 1, the air stream being applied first to smooth and stretch the leaf 3 and then, at a moment preceding or immediately following termination of the air supply, suction is applied by the device 7 to retain the smoothed leaf 3. The apparatus, Fig. 1, comprises three stations A, B, C, the belt 1 being advanced intermittently to transfer the leaf 3 from one station to the next. Within the stations A, C, vacuum boxes 5, 11 underlie the upper run of the belt 1 to provide leaf-retaining suction. The belt 1 is formed from at least transversely stretchable material, such as perforated rubber or woven material, and includes edge holding means 13 to which guide pins 14 are secured, and pins 14 running in grooves 15 of two guide rails 16. The grooves 15 run parallel to each other at a first distance apart through stations A, B, whereas at station C this distance is increased causing stretching of the belt 1 and hence further stretching of the stretched and smoothed leaf 3. Section B, Fig. 4, includes a suction box 17 which carries suction tubes 18, 19, a rubber pressure rail acting as the uppermost retaining member 32, and is mounted to a tie rod 22 for a reciprocation in a vertical direction by a cam driven lever mechanism, the box 17 being raised when conveying the leaf 3 into or out of the station B and lowered to clamp the central vein 35 of the leaf 3 during the smoothing operation. Throttle valves 10, 20, 21 are provided in pipe 9 and tubes 18, 19 to control the suction applied. Openings 33, provided in the top of the box 17, permit ingress of air, flowing in the directions shown by the arrows, when the throttles 20, 21 are opened. Where the central vein 35 is to be cut out, the station C may be dispensed with and a non-stretchable airpermeable belt 1 may be employed, e.g. a perforated steel band. In another embodiment, Figs. 7, 8, the leaf 3 is deposited with its central vein 35 over a line of suction holes 38 formed in a table 37 and is then conveyed on to a narrow conveyer belt 46 overlaid by two narrow pressure belts 47, 48 that clamp the central vein 35. Compressed air is then directed through openings 55 in tables 46, 51 to smooth and stretch the leaf 3. The leaf 3 is then transported on two suction-backed air-permeable conveyers 56, 57 past circular knives 61, 62 and a co-operating feeder wheel 63 to cut out the central vein 35.

Title: Data transmission system
IPC: H04L12/423
Filed: 1970-04-30
Abstract: The main features of the present invention reside in the fact that one or more remote groups of subordinated terminal units are serially interconnected and arranged in a closed loop which is terminated at the output and input of a master unit. Each of said groups and said master unit is connected to the transmission line via a modulator and a demodulator. In order to selectively connect a pulse equipment associated with each subordinated terminal unit, and adapted for transmission of data, with the transmission line, each of said subordinated terminal units includes a switching unit, which either connects or disconnects the associated pulse equipment from the transmission line. According to the invention, the novelty resides both in the arrangement of the network connecting the subordinated terminal units with the master pulse equipment, and the procedure for the exchange of information between the master pulse equipment and the subordinated terminal unit, and vice versa, through the closed loop, and by selectively actuating said switching unit.

Title: Information media handling system
IPC: G11B15/675
Filed: 1973-11-03
Abstract: An information media handling system comprises an information media container and a hopper which is adapted to receive the container. The hopper includes a spring biased automatic locking arm having an integral pin which during insertion of the container into the hopper enters and follows a groove in the container to a first position in the groove to lock the container into positive engagement with the hopper. Momentary application of another force in the direction of insertion disengages the container by allowing the pin to continue along and exit from the groove. Another spring then causes the container to be partially ejected from the hopper.

Title: Metallurgical process using oxygen
IPC: C22B5/00
Filed: 1974-03-26
Abstract: A continuous autogenous multi-stage process for converting non-ferrous metal sulfides, in an oscillating, elongated, gently sloped, sealed, tiltable, rounded cross-section furnace, discharging crude metal or low-iron matte at one end, and silicate slag and sulfur dioxide-rich gas at the other end. The concentrates, fluxes, commercial oxygen, sulfur dioxide, a carbonaceous reducing agent and optionally other materials are introduced into the furnace in stages to provide a molten bath of slag and matte flowing countercurrently. Slag scavenging is accomplished by deconverting to produce low grade, cleansing matte in situ in the slag layer, followed by settling. At least a substantial proportion of the commercial oxygen is continuously blown in through injectors extending through the refractory lining of the vessel and communicating with its interior below the bath surface, where necessary with a protective fluid, desirably surrounding the oxygen. Oscillation of the converter causes the injected gases to sweep back and forth through the bath, and distributes the solids over its surface to provide bath turbulence and interphase contact. Off-gases are desirably recycled. Flexible control means and special apparatus are disclosed.

Title: Power plant and system for accelerating a cross compound turbine in such plant, especially one having an HTGR steam supply
IPC: F01K9/04
Filed: 1976-09-28
Abstract: An electric power plant having a cross compound steam turbine and a steam source that includes a high temperature gas-cooled nuclear reactor. The steam turbine includes high and intermediate-pressure portions which drive a first generating means, and a low-pressure portion which drives a second generating means. The steam source supplies superheat steam to the high-pressure turbine portion, and an associated bypass permits the superheat steam to flow from the source to the exhaust of the high-pressure portion. The intermediate and low-pressure portions use reheat steam an associated bypass permits reheat steam to flow from the source to the low-pressure exhaust. An auxiliary turbine driven by steam exhausted from the high-pressure portion and its bypass drives a gas blower to propel the coolant gas through the reactor. While the bypass flow of reheat steam is varied to maintain an elevated pressure of reheat steam upon its discharge from the source, both the first and second generating means and their associated turbines are accelerated initially by admitting steam to the intermediate and low-pressure portions. The electrical speed of the second generating means is equalized with that of the first generating means, whereupon the generating means are connected and acceleration proceeds under control of the flow through the high-pressure portion.
