Title: A Method of, and Apparatus for Demultiplexing Signals
IPC: H04J1/04
Filed: 1980-03-05
Abstract: A method of, and apparatus for demultiplexing a multiplexed signal having a reference frequency. In accordance with the invention the multiplexed signal is filtered and then sampled at a controllable frequency which is greater than the reference frequency of the signal. The samples thus obtained are rearranged into different series representative of the original component signals. The phase differential between the reference frequency and the controllable sample frequency is also determined by using the different series. The controllable sample frequency is adjusted toward synchronism with the reference frequency by an amount proportional to the phase differential.

Title: Internal shoe drum brake
IPC: F16D51/20
Filed: 1981-11-03
Abstract: The brake incorporates automatic adjustment and includes an adjuster element (23) carried by one of the brake shoes (e.g. 12), a struct (19) extending between the shoes (11, 12) and engaged by the element (23) and a rotary adjuster cam (27) carried by the one shoe (12) the cam normally engaging the element in a non-rotatable manner.

Title: Rope end fitting
IPC: F16G11/05
Filed: 1982-01-26
Abstract: The fitting comprising a housing (10) with a tapered bore and an interfitting cone (11), is emplaced by threading the rope onto the housing, splaying out the end fibres thereof. introducing the cone centrally among the fibres and withdrawing the rope until the cone grips the fibres within the taper. This is done in such a manner as to leave fibres projecting beyond the cone, e.g. by 10 mm. A fluid epoxy resin is then introduced to these fibres and cured to form a plug which may be contiguous with the rear of the cone. For ropes to be subjected to high shock loading the end fitting and rope assembly is given a preload of rope proof stress proportions to establish that friction is the principal load transfer medium in the end fitting. <IMAGE>
