Title: Tipping skip release mechanism
Inventor: PERRETT JAMES
IPC: B65D88/56
Filed: 2009-04-04
Abstract: A tipping skip release mechanism comprises a main body 1, a support foot 3 under the main body, a handle 6, a release catch 7, a link pin 2, a link pin guide 4 and a locking pin 9 that can be moved between an upper locked position and a lower locked position. In the upper locked position the support foot is free to move so that when the skip is placed on a surface, the support foot pushes the link pin upwards, which in turn causes the link pin guide to press against the handle, and the handle to rotate and move the release catch, which releases the tipping skip. In the lower locked position the main body is not allowed to move. The invention allows the skip to be tipped at height without having to be operated manually, thus improving safety.

Title: Sample rate converter with gain and error adjustment
Inventor: MAGRATH ANTHONY JAMES
IPC: H03H17/06
Filed: 2008-10-13
Abstract: A sample rate converter (200) receives a first signal at a first sampling frequency (FSl) and produces a second signal, representative of said first signal, having a second sampling frequency (FSo). The converter comprises: a buffer, for storing data samples received from said first signal; and a loop circuit, for receiving first and second clock signals corresponding respectively to said first and second sampling frequencies and for generating an estimate (R) of a ratio of the first and second sampling frequencies, for outputting a write pointer so that said data samples can be stored in the buffer, and for outputting a read pointer so that said data samples can be read from the buffer. The loop circuit comprises a multiplier (106), for multiplying an error signal (e) of the loop circuit by a gain coefficient (K), wherein said gain coefficient is dynamically adjusted to change the rate of convergence of the loop circuit to the estimate of the frequency ratio, and wherein the circuit is adapted to compensate for the adjustment of the gain coefficient by correspondingly adjusting said error signal.
