Abstract: In a test circuit and method for detecting a fault condition in a voltage bus (20), the bus (20) is connected to a resistor network (22) which is coupled to a data acquisition circuit (24) including a voltage sensing means (32). In the event a zero voltage condition is detected, a constant current source (58) is connected to the test circuit and a plurality of switches (38, 40, 42) in the data acquisition circuit are sequentially operated to connect corresponding circuit paths, one of which includes a resistor (28) in the resistor network (22), sequentially to the voltage sensing means (32). A processor (25) effects comparisons of the voltage drops sensed upon operation of the switches (38, 40, 42) to effect operation of an alarm (27) to indicate the fault condition in the voltage bus (20) or to indicate a short or open circuit in the test circuit or its connections.

Title: Mig welder attachment for an electric hand drill
IPC: B23K9/133
Filed: 1987-10-23
Granted: 1993-09-15
Abstract: A dielectric cover (30) is detachably coupled to an electric hand drill (12) of pistol form with a front portion extending beyond the drill shaft projecting from the front end of the drill casing. The cover acts as a torque tube to support a right angle drive reduction gear mechanism (38) which terminates in a drive wheel (65) rotating about an axis perpendicular to the drill shaft axis (24) and within a friction drive mechanism, completed by spring biased idler wheel (54) pressing against the drive wheel. Metal blocks (42a, 42b) mounted to the cover (30) connect to one side of a DC source (122, 122) and mount a wire guide (44) for guiding a thin wire first electrode (90) into contact with and between the drive wheel (65) and the idler wheel (54). The wire electrode (90) which is frictionally pulled from a spool (92) borne by the cover (30) feeds through a conductor tube (64) of an electrode nozzle assembly (72). The conductor tube (68) receives an inert shielding gas which flows about the thin wire first electrode (90) and the arc (124). The variable speed drill (12) uses the trigger mechanism (18) to control wire electrode (90) feed speed and thus the amperage of the weld arc (124), with workpiece (116) functioning as the second electrode. Owing to the inherently stabile arc as derived from storage batteries (122, 122), arc (122, 122) and drive power (122) sources require no stabilizing interlock and may thus be entirely separate or identical, as convenience may dictate, without affecting either arc or drive either beneficially or adversely.

Title: Smear signal perturbations-compensating circuit in satellite television receivers
IPC: H04N5/21
Filed: 1988-05-26
Granted: 1992-10-07
Abstract: 2.1 In band-limited frequency-modulated transmission systems such as the transmission of television signals via satellites, a dispersal signal is superimposed onto the television signal to be transmitted before it is frequency-modulated. This leads to disturbances in satellite television receivers. In a known circuit, a correction signal characterising the amplitude of the dispersal signal is generated by evaluating the synchronisation signals and this correction signal is additively superimposed on the input signal. The novel circuit should also provide for compensation of the disturbances caused by the dispersal signal if no standard-oriented synchronisation signals are available. 2.2 This is achieved by means of a circuit which generates overshoots on a reference level of the signal. These overshoots, which differ from the useful signals with respect to their level are evaluated with respect to amplitude and used for generating the correction signal. 2.3 Satellite television receiver. <IMAGE>

Title: Charge determination method for chargeable television transmissions
IPC: H04N7/16
Filed: 1988-06-18
Granted: 1991-08-07
Abstract: In known methods for determining charges, the viewer must pay for an entire programme contribution even if he or she is following it only in parts. In the novel method, the viewer should be able to view a desired programme contribution wholly or partially and should only need to pay for the actual viewing time. For this purpose, either a charge signal per unit time or a clock signal, the transmission rate of which can be controlled, is inserted into each individual programme contribution by the transmitter. At the receiver end, the charge signal per unit time or the clock signal is used for debiting a credit account. <IMAGE>

Abstract: Electromagnetic deflection unit for use in a projection television display tube, comprising: a system of line deflection coils having two oppositely located saddle coils with their longitudinal conductor groups which are to be positioned on either side of the longitudinal axis of the display tube.

Patent EP-0305319-B1 (EP)
IPC: C21C5/46
Filed: 1988-08-12
Granted: 1993-05-26
Abstract: When converters are tapped, steel also runs out with the slag towards the end of the tapping. With a minimal amount of steel remaining in the converter, the proportion of slag also running out must be minimised in order to improve the accuracy of analytical sampling, the degree of purity and the output. The cause of slag also running out is essentially the formation of a vortex and a lowered channel above the tap hole, when the level falls below the critical steel bath level. According to the invention, a depression is therefore created around the tap hole, the depth of the depression being greater than the critical bath height for vortex formation and, to prevent the latter, the depression being provided with weirs, feeds for inert gas and/or coils for generating flows in the steel bath and measuring instruments to detect the slag also running out. The process provides that the depression is uniformly filled until the end of tapping, the stiffness of the slag is increased by means of lime if necessary and/or the melt is perturbed by pulsed introduction of inert gas and/or the vortex flow is perturbed by electromagnetic fields. By means of the novel device and the process, formation of the vortex is very largely prevented and therefore has the advantage of improving the accuracy of analytical sampling, the degree of purity and the output of steel in the tapping of converters. <IMAGE>

Abstract: A matrix pin print head of the hinged clapper armature construction includes several pin systems, where each pin system comprises a magnet yoke limb pair (1), an electromagnetic coil (2), a hinged clapper armature (3), and a print pin (4). A higher pin system number naturally results in a larger print head or nominal diameter (5). In addition, an electomagnetic coil support (11) is provided, which is produced by sintering or precision casting and which forms a single-piece component (21) together with a base plate and the magnet yoke pairs (1). In order to achieve an advantageous guiding of the armature, in particular for high-number pin systems with, for example, 18 or 24 print pins, without a loss in magnetic energy, the electromagnetic coil support (11) exhibits radially outwardly disposed individual magnet yoke limbs (1a), which magnet yoke limbs (1a), in each case, are directed to a pin engagement point (15) between the pin head (4a) and the hinged clapper armature (3), such that the radially inner magnet yoke limbs (1b) are formed to a closed ring (16) and that this closed ring (16) has attached radially inwardly directed teeth (17), where guide means (19) for the hinged clapper armatures (3), in each case, grip into the tooth gaps (18) of the teeth (17).
