Patent GB-2007067-A (GB)
Title: PAL television receiver sub- carrier regenerator
IPC: H04N9/455
Filed: 1978-10-12
Abstract: The regenerator is of the type in which the PAL signal is fed both direct and via a one-line delay 12 to an adder 14 and a subtractor 16 whose outputs pass via full-wave rectifiers 36, 38 to control a sub- carrier oscillator 50, and is characterized by a second sub-carrier oscillator 40 which is controlled by the colour burst and which also controls the oscillator 50. To ensure that the regenerator synchronizes correctly on the colour burst and maintains approximately constant phase but also follows any rapid change in the phase of the chroma signal, oscillator 50 has a larger frequency change for a given control signal than does oscillator 40. The regenerator may be used in a colour decoder in which oscillator 50 feeds demodulators 20, 24 receiving the separated chroma components. <IMAGE>

Patent GB-2034091-A (GB)
Title: Alarm circuit
IPC: G08B19/00
Filed: 1978-11-15
Abstract: A driver circuit designed to respond to one or more of a set of signals by conducting during unidirectional, transitory variations of the signals but by otherwise remaining non-conducting. The circuit includes an output driver 18 and provisions 40-48 for introducing a set of input signals. The output driver 18 is momentarily actuated via a first resistance/capacitance network 60, 62, 64 and a second resistance/capacitance network 78, 80, 82 only when the signal on a line 48 changes in one direction (ie only when switch 42 closes). The circuit further includes a light producing 92, audible 90 or other alarm device driven by the output driver 18. The alarm device indicates the presence of a unidirectional transitory varying input signal. The circuit may also include a capacitor or other filter separating the first network from the second network. This filter prevents the reaction of the second network to transitory variations of more than one input signal occurring within fixed intervals of one another, the fixed intervals being determined by the filter time constant. <IMAGE>

Title: An electromechanical device for distance measurement
IPC: G01B7/26
Filed: 1979-02-14
Abstract: An electromechanical device for measuring the distance of an object and particularly for measuring the radial clearance of rotating component 5 from a casing 8.

Title: Automatic tool changing arrangement on a machine tool
IPC: B23Q3/157
Filed: 1979-05-29
Abstract: For the purpose of a tool change a work spindle (6) is moved along a tool axis (z) out of a work position into a tool changing position and a tool changing device (9) is brought alternately into a transfer position relative to the work spindle (6) and relative to a tool magazine (7).

Patent GB-2025063-A (GB)
Title: Apparatus and Method for Detecting Electrocardiogram Baseline Shift
IPC: A61B5/308
Filed: 1979-06-22
Abstract: An apparatus for detecting baseline shift in an ECG system, in which there is a multiple element electrode (15, 16) at a given skin location and another such electrode (17, 18) at another skin location, each providing an ECG signal of negligible magnitude between the elements because of the close spacing while the pair of elements are sufficiently separated so that the motion of one element is at least partially independent of the motion of the other. Parallel ECG signals (22, 24) are obtained from different elements of two multiple element electrodes and which under normal operating circumstances would be equal. Any difference between the signals (due perhaps to an electrode becoming dislodged) is detected by logical circuitry (25, 26, 27) to produce a signal on line 26 indicating baseline shift. The baseline shift signal on line 26 will prevent the e.c.g. signal utilizing means from giving a false alarm or output. <IMAGE>

Title: Ram air turbine blade pitch control mechanism
IPC: F02C7/32
Filed: 1980-03-21
Abstract: The control mechanism includes a blade control member (23) mounted for reciprocation along a central axis (17) of the hub assembly. The blade control member cooperating with an eccentric pin (59) operatively connected to the blade (11) for controlling blade pitch, a first spring (63) being positioned between the hub assembly (12) and the blade control member (23) to cause the blade (11) to assume a coarse pitch position when the blade and hub assembly are in storage. Second spring means (47, 48) is positioned between the blade control member (23) and the slide member (41). Initial rotation of the hub assembly (12) causes the flyweight 30 to move the slide member (41) and the control member (23) bodily, to move the blade pitch from coarse pitch to fine pitch whilst. Thereafter, an increase in the rotational speed to the operating speed causes centrifugally responsive means (56) to control the blade pitch by moving the control member (23) relative to the slide member (41), against the bias of the second spring. <IMAGE>
