Title: Cable equalising circuits
Inventor: WEIGHTON DONALD
IPC: H04B3/14
Filed: 1955-09-21
Abstract: 798,401. Equalization circuits. PYE, Ltd. Sept. 19, 1956 [Sept. 21, 1955], No. 26993/55. Class 40 (4). [Also in Group XL (b)] The attenuation of a cable is equalized by means of a circuit comprising a conductive element whose permeability and resistivity are chosen so that the resistance of the element increases with frequency in a manner similar to the attenuation of the cable. The increase in resistance is due to skin effect. The element may be incorporated in the anode circuit of an amplifying valve V and may comprise a length of high-permeability wire, e.g. " Mumetal " (a Registered Trade Mark) wire, wound upon a former F. It is stated in the Specification that the desired result is achieved when the product of the square of the wire diameter and the permeability divided by the resistivity has the same value as that of the conductor of the cable. The element may be in the form of a layer of ferrite having the requisite properties deposited in a groove on the surface of a flat plate or a cylinder of insulating material.

Title: Improvements in and relating to braking mechanism
IPC: F16D49/10
Filed: 1920-09-22
Abstract: 174,673. Kelley, E. F. Sept. 22, 1920. Band; force-transmitting mechanism.-A bane brake particularly for automobiles comprises an operating lever 23 pivoted at 22 on a stud in an eye 20 at one end of the band, and connected by a link 26 which screws into a rocker 21 disposed in an eye 19 at the other end of the band. The link 26 passes through a tapered hole in the lever 23. The band is held in position with respect to the drum by a guide member 47 through which the link 26 passes and which is pivoted at 15 on a fixed plate 14 serving as a shield for the interior of the drum. The guide 47 is interposed between a spring 27 and a spacing tube 28 on the link 26. The plate 14 is mounted loosely on the axle 12 and is held stationary by a distance rod 11 with diverging arms 16 secured at 15 to the plate. The band is further held in position by pins 55, 56 which pass through members 48, 51 secured to the plate 14. The hole 50 in the member 48 is slotted but the pin 56 fits in the hole in the member 51 which is rigidly held by the member 53 secured at 15 to the plate 14. The pin 56 thus serves to anchor the band at a point which divides the band into unequal parts the larger part being effective during the forward running of the vehicle and the smaller part being effective during backward running and producing a relatively smaller braking action. The lever 23 may be connected by a pull rod 32 to a hand lever 31, the means of connection between the rod and lever 31 comprising a member having a tubular part 58 adapted to be adjustably positioned on the rod by screwing and a pair of slotted ears 42 to receive a pin 44 on the lever. The slot in the ears 42 allows for play necessary on account of the movement of the body on the bearing springs.
