Title: Method and switching arrangement for adaption of the measuring range of a delta modulated measuring system of a navigation apparatus
IPC: H03M3/02
Filed: 1976-02-04
Abstract: 1531292 Analogue to digital converter MESSERSCHMITT-BOLKOW-BLOHM GmbH 4 Feb 1976 [12 Feb 1975 23 Jan 1976] 04460/76 Heading H3H An input signal which an a-d converter decodes by integrating it at J 1  until a threshold level in SW 1  is passed, this resulting in a clocked pulse e resetting the integrator and advancing or decrementing a counter Z in a navigation computer, may be in two ranges. The range is selected by a switch Um in dependence on a time programmer ZW or signal level detector Mu, the changeover only taking place at the time of a reset pulse and if the integrator output is low. In addition to the sensitivity changeover, zero point drift in the gyroscope from which the input is derived may be compensated for by reversing the gyro spin, a second gyro and decoder (Fig. 6), locked into the same time raster being used during the reversal, similar restraints relating to the signal level being near zero during switching being applied.

Abstract: 364,900. Current and pressure meters. WATES, F. S. S., 184, Shaftesbury Avenue, London. Feb. 17, 1931, No. 5000. [Class 37.] An instrument adapted to give a direct reading of high-tension volts, low-tension volts, and milliamperes in a wireless receiving set includes a single operating coil b, one or more series resistance c, and three pushbutton switches e, f, g, contained in the instrument and arranged so that the current always flows in the same direction through the coil b. The instrument is preferably of the polarized moving iron type described in Specification 322,558, [Class 37, Electricity, Measuring &c.], and has an operating coil b of about 200 ohms resistance and a series resistance c of 4800 ohms. For measuring the voltage of the accumulator, the low-tension pushbutton f is pressed, putting the coil b directly across the low-tension terminals l, k. For high-tension readings the high-tension switch g is operated, putting the coil b and resistance c in series across the high-tension terminals l, h. For milliampere readings the switch e is depressed, breaking the normal direct connection between the low and high-tension negative terminals l, j and inserting between them the operating coil b in series with a resistance m of about 10 ohms. This resistance, which is wound with wire capable of carrying one ampere, prevents short-circuiting of the low-tension supply if the switches e, f should be simultaneously operated. The invention is also applicable to the ordinary moving iron and the moving coil types of instrument.

Limbs, artificial.-Arms in which wrist-twisting mechanism is operated by flexing the elbow are fitted with a bevel gear located near or at the elbow joint which transmits movement by means of a shaft in the forearm to a wrist element, locking gear being provided so that the wrist element may be disconnected from the twisting mechanism and locked. In the form shown in Figs. 2 and 4, the frame B carrying the forearm casing is pivoted at B<1> to the bucket of the upper arm. Mounted loosely on a transverse shaft B<2> carried by the frame B is a sleeve C carrying a bevel wheel E gearing with a bevel wheel F on a hollow shaft G to which is attached the wrist element. The sleeve C is capable of limited axial movement, and carries a guided locking-plate H', which, when the sleeve is moved to disengage the bevel wheel E, engages by means of holes H<8> the teeth of the bevel wheel F and locks the shaft C. Rotary movement is transmitted to the sleeve C by a link C<3> pivoted to the upper arm and to a crank C' which engages a slot in the end of the sleeve. The sleeve is normally held with the bevels in gear by a spring K attached to a pin H<2> depending from a sleeve H sliding on a guide-shaft H<1>. The plate H<4> is guided on a second sleeve H<5> on this shaft. A cam J is loosely mounted between the sleeves H, H<5>. The plate H' is attached to the pin H<2> by a spring to which an operating cord H<3> is attached. A pull on this cord moves the plate H<4> to lock the wheel F, and the sleeve C is held in this position by spring catches which are released by the cam J when the elbow nears the limits of its movement. In the form shown in Figs. 5 and 6, the elbow pin is carried on a hollow shaft M<3> formed on the hemispherical end of the upper arm bucket. This end is constituted by a metal spinning, the edge of which enters a groove M<2> in the bucket proper, as shown. One gear wheel E is mounted rigidly in the shaft M<3> and the other F on a shaft G on the forearm.
