Title: Scaffold platforms
Inventor: COLLIER RONALD THOMAS
IPC: E04G1/34
Filed: 1990-05-18
Abstract: A portable platform which supports a person in an elevated position is provided with a base (10) pivoted to a pair of frames (3). The frames (3) have legs (11) which slidably engage support legs (12) supported by wheels (16). The frames (3) can be swung down onto the base (10) to collapse the platform for storage or transport. When in use the frames (3) are swung into an upstanding disposition and manually releasable catches (30) lock the frames (3) upright. The height and orientation of the base (10) is adjusted by raising and lowering the frame legs (11) on the support legs (12) and by clamping the legs (11, 12) with the aid of spring loaded pins (61) which snap into bores (66) in the support (12). The pins (61) are manually withdrawn and released to permit adjustment by knobs or plungers (68). Upper cross-pieces (8) of the frames (3) combine with detachable rails (15) to form a safety rail. The detachable rails (15) and a framework (90) of the bore (10) can be adjusted to vary the length of the assembly. <IMAGE>

Title: Fine-tune frequency adjuster
Inventor: SHAPIRA YAIR
IPC: H03L7/183
Filed: 1990-06-13
Abstract: The division coefficients of two phase locked loop dividers (10, 13) are substantially simultaneously changed by amounts so that the combined change results in a small change in loop output frequency f out. The loop has an input frequency fi, a first divider D1, a voltage controlled oscillator 12 and a second divider 13. The loop may be used as a frequency adjuster in the clarifier of an SSB receiver. The changes of coefficients can be synchronised to achieve a change of both coefficients within one cycle. Calculating means (14, Fig 2) or a look-up table may be used to select coefficient changes corresponding to a required output frequency adjustment. <IMAGE>

Title: Imaging of short t2 material using sinusoidal gradients
Inventor: HALSE MORLEY ROGER
IPC: G01R33/54
Filed: 1993-01-12
Abstract: Spatial NMR information is obtained from a sample by applying a magnetic field having a static component and two sinusoidally time varying gradient components (Gy, Gz), the period of one gradient component (Gz) being preferably twice the period of the other gradient component (Gy). An RF excitation pulse is applied at the instant both gradient field components are zero. A plurality of NMR sampling responses are produced by gradient echoes in data capture windows and the amplitudes of the gradient field components are varied to provide a desired distribution of sampling path in k-space. In each data capture window the gradient field components are reversed in direction to enable all quadrants of k-space to be sampled.
