Title: Improvements in electric filter circuits
IPC: H03H7/075
Filed: 1949-05-20
Abstract: 661,715. Electric filters. E. M. G. HANDMADE GRAMOPHONES, Ltd., and DAVEY, F. G. G. March 30, 1950 [May 20, 1949], No. 13576/49. Class 40 (viii). A low-pass ladder filter is terminated by resistances a and b and the elements on the input side of a central element have reactances of magnitude k 1 a, and the elements on the output side of the central element have reactances of magnitude k 2 b and the central element which is variable has a range of reactance values including k 3 ab/(a+b) if it is a shunt element and k 3 (a+b) if it is a series element. The reactances are measured at the mean cut-off frequency and k 1 , k 2  and k 3  do not differ greatly from unity. The effect of these dimensions is that the cut-off frequency of the filter can be varied over a substantial range by adjustment of the variable element whilst maintaining a sharp cut-off. In the construction shown a series inductance L2 is the central element but, if the end reactances of the latter are shunt capacities the central element will be a variable shunt condenser.

Title: Improvements in or relating to rail contact devices
IPC: B61L1/06
Filed: 1959-04-21
Abstract: 905,561. Vehicle-operated track switches. FRYBA, J. April 21, 1959, No. 13600/59. Class 105. In a vehicle-operated track switch the relative movement between a deflected rail and a bending resistant beam operates the switch contacts. A rail 1 is secured to sleepers 4 and 5 and bridges sleepers 6, 7, 8 and 9 with a clearance equal to distance 14. A bending resistant beam 15 is attached to the rail at positions 17 and 18 and to the bridged sleepers. Attached to the beam is a switch assembly comprising spring contacts 56, 57 and 58 in an inner housing 50 which is frictionally held by pads 70 within an outer housing 45. The switch contacts are operated via a membrane 51 by a bolt 49, having a head 68 and collar 67 which co-operate with the base 52 of the inner housing to limit the bolt traverse with respect to the inner housing to a distance 14. The bolt is attached to a resilient arm 48 which is connected between the beam 15 and the rail base 2. When a rail vehicle moves over the arrangement the rail base is deflected downwards at least a distance 14 and carries with it the bolt 49 whereby contacts 56 and 57 are broken and contacts 56 and 58 engaged. Further relative movement between rail and beam is absorbed by the movement of the inner housing within the outer housing against the frictional resistance of the pads 70 whereby the traverse of the bolt 49 with respect to the switch contacts remains unaltered.

Abstract: 647,109. Double-belt sheeting-machines. FISCHBEIN, W. J., and BRITISH ARTIFICIAL RESIN CO., Ltd. May 20, 1948, No. 13669. [Class 87 (ii)] [Also in Group VIII] In a process for making sheet material by subjecting a heated mixture of comminuted material such as sawdust or loose fibrous material and a plastic bond to sustained pressure between two pressure-applying conveyers, the mixture is subjected to a high initial pressure before being pressed between the conveyers. This high initial pressure may be applied by one or more rollers or by a heated platen supported by a rolling device. This high initial pressure may be repeated in stages so that the compacting is attained prior to pressing between the conveyers. Fig. 1 shows part of a machine for doing this, comprising a roller f which applies the high initial pressure and upper and lower conveyers h, b which are made up of a number of platens as described in Specification 595,423. The lower conveyer is supported on a bed g. An endless steel band i is interposed between roller f and the material, and a similar band is provided on conveyer b. The mixture is fed from a hopper a on to the conveyer b which carries it under high-frequency heaters e and thence under roller f and between the conveyers. The height of roller f is adjustable. The roller may be internally heated. A layer of paper may be fed from roll d and applied to the material to form a facing thereon. In modifications: (1) (Fig. 2, not shown). The conveyers are bands of steel or other heatresistant material and the high initial pressure is applied by two oppositely-disposed rollers, one being below the lower band and the other above the upper band. The bands are backed by heated adjustable supports. (2) (Fig. 3, not shown). The machine of Fig. 2 is modified by the substitution of adjustable heated rollers for the supports.
