Abstract: Apparatus for analysing digital radio transmissions to indicate the condition of a transmission link. The apparatus samples received digital radio signals to produce at each sampling instant a signal or signals representative of the modulation state at that instant. The apparatus includes display means (30) for displaying a given number of the samples as an array of clusters in which each cluster corresponds to one of the modulation states. Associated with the display is a graticule generating means (80) capable of storing data indicative of a plurality of graticule configurations. The apparatus has means which enables the production on the display of a graticule configuration which is appropriate to the cluster array associated with the modulation scheme of the transmission under analysis. In addition there is an adjustment (35) which can be operated to set the relative position of the array and the graticule.

Abstract: A straight tube mass flowmeter includes upstream and downstream transducers (18, 20) arranged such that phase difference between vibration occurring at the positions of their placement may be measured. By virtue of Coriolis effects which occur when a fluid flows in the tube (6), this phase difference is a function of mass flow within the tube (6). Unfortunately the function is non-linear and sometimes has a fold back characteristic with the result that massflow cannot be uniquely determined. In an improved straight tube mass flowmeter in accordance with the present invention, the tube is vibrated at resonance and the resonant frequency measured. By taking the ratio of phase difference to resonant frequency, an output more conveniently related to massflow is provided, this output being a substantially linear function of mass flow.

Date Jan. 28, 1988.In an easy-to-open chocolate package, the wrapper has two areas (2, 3,23', 24') where the packing material is folded in two, made of two layers of packing material sealed together by their inner side, lying on an essentially even upper surface of the wrapper and laterally enclosing a tearing up zone (18, 26) of the wrapper, so that when the package is torn open the wrapper is opened up in these areas. In an embodiment as a cylindrical bag, the tearing up zones (18, 26) extend until the free edge (11, 11') of a fin (10, 10') by which the tearing up zone (18, 26) is held when tearing the package open.

Abstract: The invention relates to a magnetic field sensor (1) having a frequency-analogous output (16, 26). The magnetic field sensor (1) contains several bipolar magneto-transistors (3) which are uniaxial with respect to their magnetic-field sensitivity, as components sensitive to a magnetic field. The magneto-transistors (3) are current-feeding transistors of I<2>L inverters, several of which are combined to form an oscillator (10, 20). In a preferred embodiment, magneto-transistors (3) with dual collector structure are provided which are in each case associated with two inverters. The inverters belonging to different magneto- transistors (3) are combined to form in each case one ring oscillator (10, 20). The two ring oscillators (10, 20) supply a frequency- analogous output signal, the differential frequency of which is proportional to the magnetic field and largely independent of interfering environmental influences. <IMAGE>

Abstract: An improved balloon-tipped catheter 10 includes means for convectively heating the inflation medium within the balloon 12 during dilation. In the preferred embodiment, the convective heat is provided by a radiant heating block 40 which is attached to a laser light source through an optical waveguide 16 extending the length of the catheter 10. The convectively heated balloon 12 promotes restoration and healing of the arterial wall in the region of stenosis, which region normally suffers from cracking, tearing, and stretch­ing. It has been found that damage to the arterial wall can sometimes result in abrupt closure of the artery and frequent restenosis in the same region.

Abstract: The converter converts two binary signals (BIN+BIN-) into positive and negative bipolar pulses (BIP) corresponding alternately to a "1" logic state of the binary signals. The bipolar pulses are defined by low-impedance output states of two transfer gates (2e+,2e-). The invention aims principally to reduce the tailing effect from the trailing edges of the bipolar pulses. This can be obtained by delaying the crossing of the low-impedance state to the high-impedance output state by means of delaying the control signals for the transfer gates, or by an integrator circuit (5e) applying calibrated pulses at the output of the transfer gates, in response to the trailing edges of the "1" logic states of the binary signals. The converter also makes it possible to calibrate the rise times of the bipolar pulses and to use CMOS circuits upstream. …<IMAGE>…

Abstract: An apparatus for moulding a urethane overlay (26) on a metal wheel disc (24) includes a base mold part (202), a middle mold part (22, 24) and a clamp (206). The clamp (206) includes a funnel (312) adapted for introducing a liquid urethane reaction mixture. The funnel (312) has a nozzle passage (322) registering with a pour opening (290) in the disc (24) in the closed condition of the mold. A sprue pin (330) is affixed to the base mold part (202) and cooperates with the margin of the pour opening (290) to define a restricted access opening to the mold cavity during the injection pour of the reaction mixture. The sprue pin (330) is operable to restrict back-flow of the reaction material during gelation of the same in the cure cycle. The sprue pin (330) and disc (24) in the vicinity of the pour opening (290) define a zone of weakness in the cured urethane reaction mixture operable to induce fracture in the zone upon separation of the base mold part (202) to thereby cause cleavage of the urethane reaction material adjacent the inboard surface of the middle mold part (22, 24).
