Abstract: 1,075,614. Shrinking wrappers. KALLE A.G. Oct. 21, 1964 [Oct. 23, 1963], No. 42949/64. Heading B8C. Articles are packaged in heat shrinkable film, only part of which is subsequently heat shrunk. In the apparatus described a wrapped woollen blanket gripped between conveyer belts 3, 3a (Fig. 1) is carried past nozzles 10 which blow hot air or nitrogen on to the sides of the package. Alternatively the package may be tightly gripped between two metal plates and submerged in hot liquid, the plates gripping the package sufficiently well to ensure that no liquid penetrates between the plates and the surfaces of the package. The belts 3, 3a are as wide as, or wider than, the package and so protect the surfaces that they cover from heat. The belts 3, 3a travel round spring rollers 7 which allow slight variation in the height of the package, and a device 9 permits adjustment of the belts 3, 3a for greater variations. The positions of the nozzles 10 and guides 2 are also adjustable for different-sized articles. The surfaces of the package which are prevented from heat shrinking may be printed or perforated, before or after heat shrinking the package.

Abstract: 944,111. Packing railway tracks. F. PLASSER [trading as FRANZ PLASSER BAHNBAUMASCHINEN]. Dec. 16, 1960 [Dec. 31, 1959], No. 43449/60. Heading E1G. In a method of packing a railway track, which has been lifted to the correct height by a track packing machine 1, the packing tools 10 penetrating the ballast to an adjustable depth, the depth of penetration of the tools 10 is adjustable in dependence of the amount of lifting of the rail required locally in each case. In the arrangement shown the rail 4 is lifted by a clamp 25 and the ballast is packed beneath the sleepers 5 by tamping tools 10 operated in a known manner. The machine operates as follows. The upper chamber of a cylinder 11 is fed with a pressure medium from a pump 16 to move a piston 12 downwards to displace a pressure medium in the lower chamber of the cylinder 11 into a cylinder 23 to lift a piston 24 against a spring 26 and, through the rail clamp 25, the rail 4. Once the rail 4 is lifted to the desired height a valve 22 is closed to enable the clamp 25 to hold the rail 4 at the desired height and to prevent further movement of the piston 12. The carrier 3, supporting the tamping tools 10 is then lowered into contact with the piston 12 and determines the depth of penetration of the tools 10 into the ballast.

Abstract: 1353337 Active filters BBC BROWN BOVERI & CO Ltd 27 Sept 1971 [28 Sept 1970] 44872/71 Heading H3U  A filter comprises: a number of band-pass circuits 1, 11, 21 having contiguous passbands, and their inputs connected in parallel to a signal source U E  of varying frequency; switching means for connecting the output of any one to a common output U A ; and a logic circuit responsive to the appearance at the output of any one bandpass circuit of a signal of which the magnitude exceeds a predetermined level to connect the output of that circuit to output U A  and to inhibit the output from any other bandpass circuit. If a signal of peak level greater than that of the reference U 0  is present at the output of one of the bandpass filters, say No. 1, the comparator 2 associated with this filter will produce output pulses which pass through AND gate 3 to trigger monostable 4 to its unstable state. The duration of the unstable period is greater than a complete cycle of the lower cutoff frequency of filter 1, e.g. 2 or 3 times, so that when triggered the Q output provides a "0" signal to the AND gates 13, 23 in the other channels, to prevent their associated monostables 14, 24 being triggered. The Q output of monostable 4 provides a " 1 " signal to set bistable 5, which in turn enables gate 7 to pass the signal from filter 1 to the output U A .
