Title: Vehicle wheel mounting
IPC: B62D7/18
Filed: 1978-07-21
Abstract: A vehicle wheel mounting includes a ball joint 52 which pivotally interconnects an axle 42 and wheel spindle 22. The ball joint includes a socket housing which is connected with the axle and a rotatable ball stud 70 having a tapered shank 68 which extends into a cylindrical opening 60 formed in an arm 32 of the wheel spindle. An axially split bushing 58 has a tapered opening 72 which engages the tapered shank 68 of the ball stud. A cylindrical outer surface of the split bushing is disposed in engagement with the cylindrical opening 60 in the spindle and has a central axis 62 which is offset from the central axis 74 of the tapered opening in the bushing. Upon rotation of the bushing 58 about the central axis 74 of the tapered opening in the bushing, the spindle is moved relative to the axle to adjust wheel camber. This movement of the spindle results from the offset relationship between the central axis of the tapered opening in the bushing and the cylindrical outer side surface of the bushing. When a desired wheel camber has been obtained, a nut 104 is tightened to apply an axial force to the bushing 58. This force causes the tapered shank of the ball stud to expand the split bushing radially outwardly into tight gripping engagement with the cylindrical opening in the spindle arm 22. <IMAGE>

Patent GB-2005841-A (GB)
Title: Navigational instrument
IPC: G01C21/12
Filed: 1978-10-03
Abstract: An instrument for navigating land vehicles on uneven terrain includes attitude sensors (18, 20) which respond to deviation of the yaw axis (z<F>) of the vehicle from the vertical (z<R>). A computer computes the attitude angle or the sine or cosine thereof from the attitude sensor signals. Signals from a movement pick-up indicative of movement relative to the ground are combined with signals from a heading reference unit. The computer then transforms the heading angle (< alpha >K) measured in a heading reference-fixed coordinate system to a heading angle (< phi >K) relative to an earth-fixed coordinate system (x<R>, y<R>, z<R>) using the attitude angles (and/or their sines or cosines) and generates a signal for compensating for the drift induced in the heading reference-fixed coordinate system, an axis of which represents a heading reference direction determined by a directional gyroscope. The attitude sensors may be accelerometers (18, 20) or clinometers. <IMAGE>

Title: Line state detection circuit
IPC: H04M19/02
Filed: 1979-05-10
Abstract: To detect the condition-made or broken-of a telephone line (1g1, 1g2) a smoothing circuit (FC) is connected to one wire of that line, the smoothing circuit including a biassed diode (D) with resistors (R1, R2, R3) and a capacitor (C) to get rid of noise and other short- term line voltage fluctuations. The output of the smoothing circuit is connected to the input of a comparison circuit CC, which latter includes two voltage comparators AC1 and AC2. The comparison circuit input is connected to the non- inverting inputs of the comparators each of whose inverting input is connected to a reference voltage. For each comparator the two inputs are inter-connected via a diode. The comparator outputs are connected via respective NAND gates (ps1, ps2) to outputs (ss1, ss2) of the comparison circuit. The logic conditions of the two outputs, i.e. 00, 01, 10, 11, are inductive of the condition of the telephone line to which the circuit is connected. Its high input impedance means that it has little or no detrimental affect on the operation of the telephone line. <IMAGE>

Title: Yarn monitoring device
IPC: D04B35/14
Filed: 1979-10-04
Abstract: Yarn Y1, Y2 being supplied to a textile machine is led over a pair of spaced hooks 24 on a support member 22 and is contacted between the hooks by a pivotable member 12 when in an inoperative position (shown in broken lines). In the event of breakage of the yarn, the member 12 pivots into an operative position (shown in full lines) and operates a proximity switch 18 to halt operation of the textile machine. In the event of snatching, the increased tension in the yarn lifts the support member 22 off a magnetic block 26, again causing the member 22 to pivot to its operative position and therby halt operation of the textile machine. After the snatch has passed, a weight 27 which the support member 22 engages after initial lifting thereof returns the support member 22 to its original position under gravity and the yarn forces the pivotable member 12 back into its inoperative position so that operation of the textile machine can recommence. <IMAGE>
Patent GB-2036303-A (GB)
Title: Method and apparatus for measuring thermal neutron characteristics
IPC: G01V5/10
Filed: 1979-10-12
Abstract: The thermal neutron decay characteristics of an earth formation are measured by detecting indications of the thermal neutron concentration in the formation during a selected set of two measurement intervals following irradiation of the formation with a burst of fast neutrons. These measurement intervals may consist of a sequence of contiguous, discrete time gates which begins following a discrete time delay after the preceding neutron burst and extends over substantially the remainder of the interval between neutron bursts. The time gates are divided into a number of groups. The durations of the individual discrete time gates within the groups are equal, but the duration of the time gates progressively increases from group to group in the sequence. The duration of the neutron bursts, time delay between the burst and the start of the sequence and of the individual time gates may all be adjusted by a common, selected one of a finite number of scale factor values. The particular set of measurement intervals used is selected from among a number of possible sets as a function of a previously measured value of the decay characteristic. Each measurement interval set is used over only a specific range of decay characteristic values for which it has been determined, in accordance with a previously established relationship between the decay characteristic value and a function of the thermal neutron concentration measurements for the set, to afford enhanced statistical accuracy in the measured value of the decay characteristic. <IMAGE>
