Patent GB-2086336-A (GB)
Title: Walking Beam
IPC: B65G25/02
Filed: 1981-08-18
Abstract: A walking beam is so designed that a material to be transferred, e.g., a steel product such as a steel pipe or round bar is placed on stationary beams 8 such that transfer beams raise the material from below, move it forward and then place it again on the stationary beams, thus accomplishing the transfer of the material to be transferred. The transfer beams are formed for example into two groups 1a, 1b in a lengthwise direction and the two groups of the transfer beams are each caused to make a circular motion in the same direction by link mechanisms in such a manner that a phase difference of  pi radians, for example, is produced in circular motion between the two groups. As a result, when one of the groups of the transfer beams is raised, the other group of the transfer beams is lowered with the result that the potential energy of the lowering transfer beams is utilized for the energy required to raise the other transfer beams and the total amount of the externally applied energy is reduced. <IMAGE>
Patent GB-2107142-A (GB)
Title: Frequency synthesisers
Inventor: INCE PAUL JAMES
IPC: H03L7/197
Filed: 1981-10-07
Abstract: A frequency synthesiser comprises a phase lock loop (3), which includes a frequency divider (5) arranged to divide the output frequency by the divisor value N. To achieve small frequency steps in the output value, the frequency divider is arranged to simulate a required division ratio N, x, where N is an integer and x is a fractional value, by repetitively changing the division factor by a constant integer value of at least two (eg from N-1 to N+2) to provide fractional division factors. Since the effective required divisor value lies between N and N+1, it is possible to arrange that switching between the two actual divisor values of N-1 and N+2 can occur very rapidly. The technique of fractional -N frequency synthesis inevitably introduces phase modulation within the phase lock loop at the output of the frequency divider, which, if allowed to remain, would introduce quite unacceptable noise in the output signal and in order to compensate for this, a phase modulator (6) is included in the loop. The required switching of the division factor is achieved by an accumulator (9) which also provides the correction signal fed to the modulator (6). <IMAGE>

Patent GB-2133928-A (GB)
Title: Coatings for semiconductor devices
Inventor: GOODFELLOW ROBERT CHARLES
IPC: H01L23/29
Filed: 1983-12-02
Abstract: The performance of semiconductor devices having p-n junctions is often impaired by current leakage across the junction at the surface of the device where the p-n junction is exposed. Coating the junction with a conventional insulator, such as silicon, aluminium or titanium oxide is not very successful for reducing this leakage and whilst nitride and oxide layers deposited on InP and InGaAsP semiconductors make good insulators, charge accumulation at the oxide/ semiconductor interface can cause adverse effects on performance. It is thus proposed to use the group III-V ternary compound AlAsSb or AlGaAsSb as a semi-insulating passivating medium (22) for InP and InGaAsP devices and as an insulating material in MIS devices. <IMAGE>
