Abstract: 1. A Doppler-radar device consisting of two generally parallelepiped cavity resonators, having substantially identical dimensions and mutually connected by a lateral wall (3) common to the two cavity resonators and comprising a coupling aperture (4), wherein the first cavity resonator (1) is sealed at its end remote from the coupling aperture and the second cavity resonator (2) has an open end face directed towards the object (5) to be measured, and wherein an oscillator diode (9) is arranged in the first cavity resonator (1) and a (first) receiving diode (10) is arranged in the second cavity resonator (2), characterised in that a second receiving diode (20) is fixed in the second cavity resonator (2) and that the first receiving diode (10) is arranged at a distance of (2n + 1) lambda/8 and the second receiving diode (20) is arranged at a distance of (2n + 3) lambda/8 from the wall (16) of the second cavity resonator (2) opposite the open end face, where n equals zero or a natural number and lambda is the wavelength of the central frequency of the oscillations which are excited in the first cavity resonator (1), and that both a frequency change of the received radiation conditional upon motions of the object (5) to be measured, and also its assigned phase difference dependent upon the direction of motion of the object are determined at the receiving diodes (10, 20), where the phase which is measured at the one receiving diode (10 or 20) serves as a reference phase, whereas the deviation therefrom is determined at the other receiving diode (20 or 10 as the case may be).

Abstract: detector comprising two D-type flip-flops (701) and (702) which are arranged so that in response to data pulses DP and clock pulses CK they produce respective pulse sequences 01 and D2. An exclusive OR gate (703) receives the pulse sequences 01 and D2. and an exclusive OR gate (704) receives the pulse sequence 01 and the data pulses DP. The clock pulses CK can be up to one half a clock pulse period late or up to one half a clock pulse period early relative to a desired phase relationship of the clock pulses CK with the data pulses DP. Accordingly, as the actual relative phase is correct, late or early, the duration of the logical output from the gate (704) will be the same as, relatively longer than or relatively shorter than the duration of the logical output from the gate (703). The two gate outputs control respective current sources (707) and (708) of a current source circuit (705) to feed current into an extract current from a capacitor (203). The voltage across the capacitor (203) serves as a control voltage for altering the phase of the clock pulses CK as produced by some form of oscillator to tend to bring it into the desired phase relationship with the data pulses DP.

Abstract: A device for hooking and unhooking keys carried by a key holder comprising a key holder body (10) and a ring (11) containing an open portion sufficiently large to enable keys to be hooked on to and unhooked from the ring; the ring rotates in a slot (13) of circular arc configuration provided within the body (10) and of length such as to contain in its interior a ring portion (11) of greater length than the open ring portion; a portion of the slot (13) is constricted by an arcuate flat spring (18) which presses on to the ring (11), and of which the curvature (19) is such that when in its rest position it lies between the edges of the open portion (12) in order to prevent accidental rotation of the ring; the elasticity of the spring (18) is such as to enable it to deflect under the force exerted by the manual rotation of the ring, thus withdrawing from the open portion.

Abstract: A transmitter for transmitting FSK-modulated signals by means of an inductive aerial. With a large frequency deviation, such as with FFSK-modulated signals, and a high transmission rate, which may cause the occurrence of a non-constant envelope electronic equipment arranged in the vicinity is subjected to a greater degree of interference than with a small modulation depth and a low transmission rate. By generating in the transmitter and aerial current whose amplitude changes inversely proportionally to the frequency, tuning is not necessary and still a constant envelope is obtained.

Abstract: An improved method for separating a slurry (e.g a slack wax (12) into a crystallized component (e.g. a wax fraction (52) and a liquid (e.g. a lube oil fraction) is disclosed. In a preferred embodiment, the method comprises passing the slack wax (12) into a first mixing zone (20) and subsequently into a second mixing zone (30). Solvent selectively miscible with the lube oil fraction is added to the zones (20, 30). The temperature of the solvent added to the second mixing zone (30) through manifold (36) is substantially higher than the temperature of the solvent added to the first mixing zone (20) through manifold (26). This process produces a wax fraction (54) having a relatively low lube oil content.
