Each processor contains subsidiary devices such as calculator RW, working register AR, storage control device SS and memory SP, input/output device EA coupled to peripherals PE and a program interrupt device PU, coupled together via a data distributor line DL and controlled via a line SL coupled to the control unit. Each processor also contains a control and monitoring device BW and a diagnosis link DA. The control and data distributer lines and control unit PL are connected to their respective diagnosis link and the control unit and the diagnosis link of one processor are connected respectively to the diagnosis link and the control unit of the other processor, the connections allowing two way transfer. Each diagnosis link contains registers and a comparator, the register holding control words supplied by the control unit of the other processor and the comparator acting to stop a control program if a result obtained from its processor does not agree with a result calculated by the diagnosis program from the other processor.

[Also in Division H4] An electric control circuit, e.g. for controlling the switching of amplifier channels in a twoway communication system, comprises two paths fed with respective first and second signal inputs and whose gains are controlled by the respective second and first signal inputs so that the output of the first path is proportional to the ratio of the first and second input signals and the output of the second path is proportional to the ratio of the second and first signal inputs. The control path outputs may control a bi-stable circuit whose output operates switches in the amplifier paths of a loud-speaking telephone. Fig. 1 shows an embodiment of the control circuit in which the two channels 10a and 10b each include a potential divider consisting of resistor 14a (or 14b) and diode 23a (or 23b). The impedance of the diode and therefore the gain or loss in the channel is controlled by the current flowing through the diode, which current is derived from the other channel input via the amplifier 18b (or 18a) and the rectifying circuit and filter 20b, 21b and 22b (or 20a, 21a and 22a), so that the output signal of the channel is proportional to the ratio of the signal in the one channel and the signal in the other channel.

Abstract: 1,114,051. Electricselective signalling. WESTERN ELECTRIC CO. Inc. 11 May, 1965 [11 May, 1964], No. 19770/65. Heading G4H. [Also in Division B8] An apparatus for detecting the absence of a strand to be wound on a cable comprises gated photo-electric detectors. Each binder head, which rotates about the cable axis and carries the strand spools, has on it a reflecting strip which is detected by a photo-detector, thereby providing gating pulses whose frequency and duration varies.with the speed of rotation of the head. Photo-detectors, one for each strand, are mounted on a fixed support and generate a pulse each time a strand is detected. For a pair of strands, two photo-detectors are so arranged that their respective outputs, when gated, contain only pulses relating to one and to the other strand. These gated outputs set and reset a toggle which feeds a flip-flop whose unstable state is sufficiently long to maintain a relay operated even at low binding speeds. If a strand breaks, the flip-flop, and hence the relays, are no longer operated, this stopping the binding and initiating an alarm. Single strands are detected by turning the gate on permanently.

A single-phase motor has main and starting windings 2, 3, and a PTC-resistor is connected in series with the starting winding. This resistor has a stable operating point on either side of the peak of its current-voltage curve, the resistor being at the low-value stable position when it is heated only by the starting current. A heating resistor 8 is connected across the supply lines, and delayed by its mass and by a thermal insulator 9, affects the resistor 7 only towards the end of a selected period. The resistor then changes over to its other stable operating point so that the starting current is reduced to a low value. The resistor 8 may be energized for the entire running period of the motor, or may be switched on only for a brief interval towards the end of the starting period. The resistor 8 may carry the main winding current, or it may be in parallel with the starting winding.

Abstract: 1,062,964. Space heater; air supply for gas stoves. P. KREIS. July 9, 1964 [July 11, 1963; Oct. 17, 1963], No. 28273/64. Headings F4S and F4W. A gas or liquid fuel fired heater comprises a combustion chamber 2, Fig. 1, containing at its bottom end a burner 6, characterized in that the chamber rises vertically into the enclosure to be heated and has connected to it a heating chamber 9, which downwardly deflects the flow of rising hot gases, and is thermally insulated from this flow by insulation 3. Combustion air enters orifices 7 and leaves the cylindrical combustion chamber at 4, the flow descending through compartment 9 and being disturbed by deflectors 18 and 19, and leaving via exit spigot 13 whose aperture 16 extends to the atmosphere and is screened from the incoming fresh air by baffle plate 22. External flanges 15 fix the heater to a floor. External ribs or fins (25), Fig. 2 (not shown), may be provided on the casing (10) to increase heat emission. Fig. 8 shows a heater where the heating chamber 115 is disposed to one side of the combustion chamber 101 and comprises deflecting channels 109, 110, 111 and 112 alternating with cross channels 106, 107 and 108 forming 180 degree deflectors. Air spaces 116, 117, 118 and 119 provide heat insulation between the various sections. The fresh air and waste gas orifices are placed below the space to be heated. At a level with the burner orifices there are transverse slots or gaps 128 to reduce flame noise. Fig. 4 shows the heater to be made from two parallel side walls 120 which are cut to provide the air insulation gaps, and are interconnected by cross-walls 121 to define the combustion and deflection chambers. Bolts passing through bores 122 clamp the heater parts together. Fig. 5 (not shown) shows how the heater can be made from two welded shells joined to a central portion. The waste gases may leave the heater through an aperture (113), Fig. 3 (not shown), or enter an annexe chamber 213, Fig. 8, and leave via a chimney pipe 230 through a wall or roof. The pipe 235 serves to remove any condensation which may form. The heater may be mounted on a box structure 242, Fig. 12, with the burner assembly and annexe chamber extending into the compartments separated by partition 249 (Figs. 11 and 14, not shown). An extension of the box extends through an outer wall 241. One of the burner orifices may be covered with a metal screen to form a pole for a sparking plug which will initiate combustion.

Title: Photoimaging processes and compositions
Inventor: CORDES WILLIAM FREDERICK III
IPC: H01L21/30
Filed: 1986-10-14
Abstract: The step-on-wafer process, also known as the step-and-repeat alignment process, for the production of very large scale integration (VLSI) microcircuitry with multi-layer interconnects, is greatly facilitated by incorporating, into at least the first layer of photoresist, a dyestuff which meets certain criteria the chief of which is that it be transparent to radiation to which the photoresist system is sensitive and that it absorb radiation of a wavelength to which the photoresist system is not sensitive. The use of photoresist systems in association with such dyestuffs has additional advantages. For example, the thickness of the photoresist layer deposited on a substrate can be checked prior to imaging without activating the photoresist.
