In a wrapping machine, each article G is fed through a folding tube 1, together with a wrapper which is folded into U-shape about the article, by means of one of a number of drivers 5, each pivotally connected to a pair of endless claims 8 by rods 15. The drivers are guided by rollers 13, Fig. 2 (not shown), running in a pair of spaced hysteresis-shaped stationary rails 14, their direction of movement being instantaneously reversed as the rods 15 traverse wheels 6 and 7. Each operating stroke of a driver 5 carries an article G into a vertical web E, from which a wrapper is severed, through folding tube 1 where plates 2, 3 fold the extending ends of the wrapper, and finally to a position where folders 25, 26 may complete the folding at the rear of the article. The driver is reversed at the end of its operating stroke and is caused to move on the lower branch of the hysteresis by mechanical switches 17. These switches are weighted to assume the position shown and are movable to allow forward movement of the driver along this top branch, but prevent rearward movement therealong. Return to the top branch is effected by similar switches 18. Pivoted pusher plates 10 are held in an operative position by magnets 22, Fig. 3 (not shown), but are rotated through 90 degrees by a pivoted pawl 21 as the drivers 5 are reversed to minimise the opening required in table 16. Passage for pivot pins 27, which connect rods 15 to the chains 8, is effected by pivotable parts 28, 29 of the rails 14.

Title: Drive rod assemblies for nuclear reactor control rods

Filed: 1970-10-09
Abstract: 1282083 Controlling reactors SIEMENS AG 9 Oct 1970 [11 Oct 1969] 48215/70 Heading G6C Means for driving the control rod of a nuclear reactor comprises a hollow drive rod 3 fitting with small clearance in a pressure tube 2, extending from the reactor vessel 1, and movable (in the embodiment illustrated) by a pawl-type step-by-step drive mechanism (not shown) operated by electromagnetic coils 7. A control rod 34 is suspended from the lower end of the drive rod 3 by means of a coupling 33. A draw rod 4 inside the drive rod 3 serves to actuate the coupling 33. Coolant inlet ports 32 and outlet ports 31 are formed at opposite end regions of the drive rod 3. But for the provision of a slidable closure member 5, which normally rests upon an inner shoulder 35 of the drive rod 3 and in this position closes the outlet ports 31 (as shown on the left-hand side of Fig. 2), an undesirable convective flow of the coolant would be set up through these ports. On a rapid downward movement of the drive rod 3, for reactor shut-down, the pressure of the coolant within the drive rod 3 lifts the closure member 5 so that the outlet ports 31 are freed (as shown on the right-hand side of Fig. 2). Coolant within the guide clearance of the closure member 5 escapes to the outside through small equalizing ports 36. On completion of the downward movement, the closure member 5 descends under its own weight to again close the outlet ports 31. A pressure-equalizing flow of coolant occurs (as indicated by the chain lines) during the descent of the drive rod 3. The prevention of heattransferring coolant circulation when the drive rod is stationary avoids the heating of apparatus situated outside the pressure tube, e.g. the coils of the drive mechanism and any positionindicating coil, which would otherwise occur. The pressure tube may extend within a flue (Fig. 1, not shown) which constrains gas to pass in thermally-conducting relationship over the external surface of the tube, so as to cool the tube.

An ink-ribbon guide for a vibrator 11 has two ribbon guiding recesses 15 on opposite edges defined by outwardly directed upper and lower lugs 16 and 21. A gate structure 18 formed of stiff wire and comprising a pivotally mounted gate arm 19, spans each recess 15 to form a closed ribbon guiding eye 22, Fig. 2. Each arm 18 is constantly biased (either by gravity or by a spring not illustrated) to assume a closed-eye position, but is so mounted that when a stretch of ribbon is lowered behind the guide and pulled forward into the recesses (Fig. 3), the arms 18 are pushed to the open-eye position by the ribbon and then drop behind the ribbon to the closed-eye position (Fig. 4). The wire of each arm 18 is extended beyond the pivot bushing 17 formed in the upper lug 16, to form a handle 26. The handles 26 enable the arms 18 to be moved to the open-eye position (Fig. 5) to facilitate ribbon removal. In an alternative embodiment (Fig. 6) each gate arm (39) of moulded polyethylene has a hole (49) in line with a hole in the upper lug (37). A U-shaped member (48) has one leg (47) extending pivotally through the hole in the lug (37) and fitted to the hole (49) in the arm (39). The outer leg (51) of the U-shaped member is press fitted into a hole of an arm (46) forwardly extending from the gate arm (39). As an alternative, gate arms of shorter length reaching toward each other from both lugs 16 and 21 may be provided.

Title: Process for the production of repeatedly frothable foam glass
Inventor: SCHULZ ERNST OTTO
IPC: C03C11/00
Filed: 1964-11-30
Abstract: Repeatably frothable foam glass is made by a process comprising grinding glass with a SO3 content of at least 0.5% by weight in the presence of 0.15-0.30% of active soot, or the equivalent quantity of another C carrier, to a specific area of 5000 cm.2/g. or more, and providing at least 0.7% wt. water, which mainly adheres to the surface of the glass.  The water may be supplied by use of water, steam or moist air.  The resulting substance which may be in a mould or on a free surface is heated so rapidly to 200 DEG  C. above the m.p. that a thin continuous gas-tight external glaze coating is formed.  The entire portion is then heated to 800-900 DEG  C., whereupon foam glass results. The residual SO3 content is still sufficiently high for it to be reground, if necessary being replenished with C, and used again as above. The glass preferably gives in boiling water more than 1 mg. of Na2O per g., and contains not more than 7% wt. alkaline earth oxides.  In an example, a glass containing in per cent by weight SiO2, 74.5; alkali oxide, 19; alkaline earth oxide 6.5; and SO3, 0.8; is ground with active soot and treated as above.

A coherent light pulse from a source 5 is split by semi-reflecting plates 8 to provide M beams directed at the M words, the time taken for light to traverse the distance between adjacent semi-reflecting plates 8 being greater than or equal to the duration of the pulse provided by source 5. A beam deflector 7 operates to select different pages, there being, for example, a second page of words 12. A photo-detector 21 controls a binary counter 19 which, together with an address comparator 18, causes those words specified by a control circuit 22 to be passed through gates 15 to shift registers 16. The optical recording 10 may have data recorded in two dimensions (Fig. 2, not shown) the light pulse from source 5 being split in two stages (Figs. 3, 4, not shown), by semi-reflecting plates, the necessary delays between successive beams being produced by multiple reflections between mirrors. Additional data may be similarly recorded such that the recording has to be rotated or translationally moved for reading this data. The optical recording 10 may be a holographic recording or the value of each bit may be represented by the transparency of the recording in which case an optical system (Fig. 6, not shown) may be included between the recording 10 and the photo-detectors 13.
