Patent EP-0031891-A2 (EP)
Inventor: TERMAN LEWIS MADISON
IPC: G11C19/36
Filed: 1980-11-20
Abstract: A digital-to-analog conversion (DAC) circuit (32) and trigger comparator (34) combination is described for encoding and decoding charge packets in a common-well multi-level signal charge-coupled memory device (CCD). The DAC circuit, which may be of the weighted capacitor type, is used to generate a staircase waveform and to create the common-well under a first gate (14) in the CCD. The trigger comparator adjacent to a second gate (16) in the CCD is a detection circuit which stays in one binary state until an input charge signal is received, whereupon it switches state, In particular, the weighted capacitor DAC contains an extra offset bit which is used in the analog-to-digital or regeneration operation such that when the trigger comparator (34) switches state, the digital input to the DAC (32) at that time correctly represents the signal charge being converted. In one embodiment a circular serial-parallel-serial memory structure (37) is employed as the multi-level CCD memory system.

Abstract: The invention relates to a device intended for protecting from the flame action a glass pane mounted on the hearth of a fireplace for the purpose of restricting the flow of air being drawn from the surroundings through the flue under natural draft conditions. The technical problem to be solved is that of providing a simple and economically convenient device which can prevent the glass pane from overheating and blackening over its clear portion owing to the tarry residues of combustion. The solution to the problem is provided by a protective device, which comprises air conveying shaped interspaces adapted to convey air parallel to and in close contact with the glass pane (2) surface facing the fireplace (1) interior, and to create, by virtue of the draft action applied by the flue, laminar airflows which creep along the inner side of the glass pane (2).

Abstract: Olefinically unsaturated rubber e.g. butyl is continuously halogenated in an extruder-reactor having in sequence a feed zone, first flow restrictor, reaction zone, second flow restrictor and neutralization zone. Rubber in the feed zone is formed into a cohesive mass and delivered to the reaction zone where halogenating agent is injected at a filled position and the reactants are subjected to a high degree of mixing; the first restrictor hinders backflow of halogenating agent. Halogenated rubber product mixture is conveyed past the second restrictor, serving to hinder backflow of a neutralizing agent which is injected at or adjacent the downstream end of the restrictor to neutralize the mixture in the neutralizing zone.

Abstract: The suspension device for a lattice girder (10) whose top boom consists of two parallel round bars (9) has a sheet-metal vertical suspension strip (3) whose lower end is constructed as an anchoring part (4). The anchoring part (4) is an inverted T-shape and grips with two horizontal arms (6) under the two round bars (9), between which the middle part (5) of the anchoring part (4) is situated. Two resilient blocking tongues (7) extend downwards parallel to the middle part (5) and form with the two horizontal arms (6) of the anchoring part (4) an interspace which is narrower than the width of the round bars (9). During assembly, the suspension strip (3) is introduced between the two round bars (9) in the longitudinal direction of the lattice girder (10) and turned. In so doing, the two blocking tongues (7) yield resiliently and allow the two round bars (9) to enter the recesses (8) provided for them on both sides of the middle part (5). Thereafter, the two blocking tongues (7) prevent detachment of the suspension strip (3). <IMAGE>

Abstract: Pulse-Doppler radar sets operating in a relatively high frequency range, eg. X-band, are employed in the detection and recognition of hovering helicopters. The frequency range situated below the lower limit frequency of the double filter for suppression of permanent echoes is checked by means of a chain of speed filters for the spectral lines of target echoes which exceed a prescribed threshold. The signal components of all the individual filters of the filter chain which remain below the threshold, are added together using an output signal of the Doppler filter and fed to a threshold circuit for target decision. <IMAGE>

Abstract: In a three phase welding power supply, the three phase power is connected to a welding arc by a power control circuit having three conducting paths for straight polarity current and three conducting paths for reverse polarity current. The power control circuit comprises a three phase bridge rectifier circuit (112) having eight bridge arms each including a silicon controlled rectifier (1, 2, 3, 4, 5, 6, 7, 8) with the bridge circuit being connected between the three phase power source (102) and the welding arc (124) which is in turn connected to the three phase power supply neutral (103). An inductor (116) is connected across the direct current terminals of the bridge circuit so that arc currentflows in one direction through the inductor (116) regardless of the polarity of the arc current. The conducting paths are selectively activated at nonzero voltage points to conduct repetitive sequences of independent numbers of straight polarity half cycles of arc current followed by independent numbers of reverse polarity half cycles of arc current to the welding arc. Pulses are generated in synchronism with each of the three power phases and counted to determine the activation sequences of the conducting paths. By controlling the generation of the pulses and the counts of the pulses at which the paths are activated, a variety of sequences are generated.

Abstract: A picking tool adapted to open a cylinder lock of the axial pin tumbler type having its tumblers arranged in a coplanar configuration, includes a planar torquing core insertable into the lock keyway in a longitudinal direction, a plurality of longitudinal guideway channels formed on opposing faces of the core, and respective tumbler probes longitudinally reciprocable in the channels. A holder, which acts as a handle for manipulating the picking tool, also serves as a housing surrounding the core and the probes. The holder is formed with a pair of radial openings in opposite sides thereof which receive respective brake segments for exerting a frictional drag on the probes. An adjustable hoop clamp surrounds the brake segments for manually adjusting the frictional drag, so that the proper tumbler displacement action can be achieved. Setscrews are threaded into the body of the holder for clamping the probes in their final tumbler- displacing positions. At the rear of the holder, the tail ends of the probes fan out circularly so that they can be more easily manipulated individually. The probes have indicia from which the lock code can be read out after the probes reach their final positions.
