Title: Wall plug
IPC: F16B13/06
Filed: 1971-06-29
Abstract: 1343199 Wall plugs A FISCHER 29 June 1971 [8 Aug 1970 3 Sept 1970] 30407/71 Heading F2H A wall plug for use in a wall of soft or porous material comprises a generally cylindrical expansible sleeve 2, having leg portions defined by longitudinal slots 3 extending from one end, and a generally cylindrical expander 4 with the same number of triangular laminar wings 6 as there are leg portions of the sleeve, so that each leg portion is expanded outwardly by a respective wing 6 when the expander 4 is drawn into the sleeve 2. The slots 3 have transverse slots 11 at their inner ends to facilitate spreading apart of the leg portions. In Fig. 1, the expander 4 forms the head of a bolt 5. In Figs. 3, 4 (not shown) the expander is a nut held captive in the sleeve by inturned flanges at the tips of the leg portions. The wings project through recesses 14 in the leg portions. In Fig. 5, the sleeve 2 comprises two sheet metal pressings 15, 16 which when laid together form longitudinal ribs 17, 18, the pressings being spot-welded together at 19. The expander comprises an internally screw-threaded cylindrical core 4 round which are secured sheet-metal pressings 20, 21 forming the wings 6. To install a wall plug, a hole is drilled in the wall whose diameter corresponds to the outer diameter of the sleeve 2. The plug is then driven into this hole, the wings 6 (and the ribs 17, 18 in Fig. 5) penetrating the wall material surrounding the hole. Finally the expander 4 is drawn into the sleeve to bend the leg portions outwardly into the material surrounding the hole, as in the lower half of Fig. 1.

A rolled capacitor is sealed against moisture by wrapping it in a sheet of plastic B of width greater than the length of the capacitor A so that tubular extensions are formed which are subsequently filled with resin, a large part at least of the inner surface of sheet B being coated with a synthetic resin (e.g. an epoxy resin) to ensure that the wrapping adheres together. The resin is cured after wrapping, a casting resin (also an epoxy resin) being then used to fill the tubular extensions. The capacitor may consist of interleaved layers of polyethylene terephthalate and metal (e.g. aluminium) foil, the dielectric may be paper impregnated with polystyrene, or alternatively, the electrode layer may be applied to the dielectric by vacuum deposition. The sheet B may be polythene or one of the polyethylene terephthalates. In another embodiment (Fig. 5) a length of metal foil D is interleaved with the sheet B, the foil also being coated with resin and the tubular extensions may be spun over as shown before they are sealed. The ends of the wrapping may first be coated with casting resin before the extensions are sealed. The terminals may be secured to the capacitor by the wrapping (Fig. 7, not shown).

Filed: 1924-12-22
Abstract: 226,816. Johne-Werk Grafische Maschinen-Akt.-Ges. Dec. 22, 1923, [Convention date]. Rotary offset machines. -A rotary offset machine is constructed with two coacting offset cylinders c, d which each receive multiple impressions from plate cylinders a, b, the diameters of which are a multiple of the offset cylinders c, d. The sheets to be printed are fed from a feed table 13 to grippers 11 on the offset cylinder d at the same time as the cylinder c comes into contact with the final printing-plate on cylinder a. At this time also the cylinder c, which is normally in the dotted line position out of contact with cylinder d, is moved in an orbit concentric with the cylinder a into contact with cylinder d, whilst preserving its contact with cylinder a. The sheet is thus perfected with two or more offset impressions, and after this is delivered by grippers 14 on chains 15 on to a pile 16.

Abstract: 799,064. Water-tube steam boilers; regulating steam temperature. BABCOCK & WILCOX, Ltd. Oct. 11, 1956 [Oct. 24, 1955], No. 30972/56. Classes 123(2) and 123(3) A steam generating and heating installation comprises two similar boiler units 10, 12 spaced apart lengthwise of a common steam and water drum 14. The unit 10, which is shown in Fig. 2, comprises an upright furnace 56 lined with steam generating tubes extending between lower headers such as 44, 92 and upper headers such as 74, 98 which are respectively connected by downcomers and circulators to the drum 14. Combustion gases flow from the upper part of the furnace between the platens of a secondary superheater section 182 into a lateral pass locating another secondary superheater section 188 and a primary superheater section 190 and then flow downwards in a pass 192 in which are disposed other primary superheater sections 194, 195, 196 and economiser tube banks 200, 202. Provision is made for recirculating flue gas for steam temperature control, a fan 208 withdrawing the gas from the bottom of the pass 192 and discharging it into the bottom of the furnace 56. The unit 12 is identical except that the secondary superheaters 182, 188 are replaced by reheaters. In order to minimize the path of travel of water longitudinally of the drum 14 and to give an equalizing effect upon temperature along the drum and upon the fluid circulation of the units 10, 12, the downcomers and circulators are cross-connected as shown in Fig. 1. The downcomers 18, 19 of the unit 10 are connected to the drum 14 at points opposite that unit and at points 26, 38 opposite the unit 12 by branch pipes 24, 36; the downcomers 20, 21 of the unit 12 are connected to the drum 14 at points opposite the unit 12 and at points 30, 34 opposite the unit 10 by branch pipes 28, 32. In a similar way the upper collector headers of each unit are connected by circulators to the adjacent and remote parts of the drum so that the two units are tied together in a single circulatory system. Specification 526,825 is referred to.

Abstract: 504,408. Displaying. ERICSSON TELEPHONES, Ltd., and DICKINSON, W. Nov. 16, 1937, No. 31431. [Class 3 (i)] An indicator for displaying variable information comprises an endless flexible display band 1 driven by an epicyclic gear train the elements of which rotate only in planes parallel to one another or only in one plane. The band is driven by marginal perforations 5 engaging sprocket wheels 4 on a hollow shaft 2 having intermediate band-supporting rings 6. A series of brushes 8 bear on theband, and contact through rows of slots 10 with contact bars 7 carried by the shaft 2, a slot 10 being omitted in each row to determine, in known manner, which portion of the band shall come to rest at the display face. The power unit is a motor 18 belt-driving a double pulley 11 on which, and on a plate 15 attached to the shaft 2, is journalled the planet-carrying cage 20 of the epicyclic gear. The cage holds one or more pairs of pinions 25, 26 geared together, and meshing relatively with toothed wheels 14, 16 on the pulley 11 and plate 15 respectively. A slot 23 in the plate 15 is adapted to be engaged by a catch 27 forming part of the armature 28 of an electromagnet 29 controlled by the brushes 8, the catch being adapted also to enter slots 30 in the cage 20. Thus either the shaft 2 or the drum 20 is always held stationary, a helical spring unidirectional clutch 19 being provided to hold the shaft from rotating with the pulley when the catch is in the mid-way position. The epicyclic gear wheels may be partly externally toothed and partly internally toothed, or they may be replaced by frictional elements. The shaft 2 may rotate in the same or in the opposite direction to the pulley 11, and the gear may form a reduction gear, and may be reversing. Further, the cage 20 may be fixed to the shaft 2 and control effected at a sun-wheel, or be fixed to the pulley with a sun-wheel as the controlling element, or control may be effected by stopping or freeing the rotation of the planet wheels relatively to the cage 20. A plurality of bands may be employed adjacent to one another and coupled to a common motor. Specification 437,914 is referred to.
