Abstract: ELECTROCHEMICAL CELL              Abstract of the Disclosure A primary electrochemical cell of a design for reduc-ing parasitic self-discharge of the cell during storage and subsequent discharge of the cell.  The cell includes a tubular porous carbon cathode structure within a metal housing of the cell and spaced from an anode structure by an insulative separator material.  The carbon cathode structure and the anode structure are exposed to an elec-trolytic solution including a reducible soluble cathode (e.g., thionyl chloride) which is catalytically reduced during discharge of the cell at the surface of the carbon cathode structure.  The anode structure includes an elongated, cylindrical, lithium member located centrally within, and spaced from, the housing, and an electrically-conductive metal assembly at the potential of the lithium electrode and connected between the lithium electrode and a feedthrough member provided in a top cover for the housing.  All or portions of the electrically-conductive metal assembly, as well as the feedthrough member, are selectively covered with a sufficiently chemically-stable, catalytically-inert anti-parasitic discharge material for preventing the undesirable catalytic reduction of the soluble cathode at the surfaces of the electrically-conductive metal assembly and feedthrough member covered by the anti-parasitic discharge material.

Abstract: ABSTRACT:         An apparatus for optically scanning a disc-shaped record carrier, which apparatus comprises a radial tracking control system which employs a radial error signal obtained by comparing two signals supplied by two radially adjacent detectors. In order to correct tracking errors caused by deviations between the signals supplied by the two detectors the correlation between the radial error signal and the amplitude of the information signal being read is measured. The control signal obtained by means of this correlation measurement controls a balancing amplifier-circuit for balancing the two signals supplied by the detectors. Suitably a signal of predetermined frequency is in-jected into the control loop to cause the scanning beam to oscillate relative to the track so as to improve the correlation measurement. This injected signal may also be used for stabilizing the loop gain in the radial tracking control loop.

Abstract: ABSTRACT OF THE DISCLOSURE           Methods and apparatus adaptable to continuous production of hydrogen sulfide by chemical reaction of sulfur with a gaseous sulfur-reducing reactant selected from methane or other hydrocarbons, hydrogen carbon-containing compounds such as carbon disulfide, gases with high CO contents, e.g., from gasification of coal, or mix-tures of such gases are provided utilizing a separately-fired sulfur heater to vaporize liquid sulfur feedstock.  Adding steam with the sulfur reduces the temperature level require-ments of the sulfur vapors and provides H2 and O2 for the hydrolysis reactions.  Control of the temperature of the sulfur vapors and steam delivered into the system through the sulfur vaporizer is used to modulate sulfiding reaction temperatures.  A major portion of the steam is introduced with the sulfur vapors; a minor portion of the steam can be added with the feedstock reductant gas to assist in heat recovery from the reaction product gases and to facilitate standby conditions.  During production, the system is operated at pressures above atmospheric as determined by a back pressure established in removing product gases containing hydrogen sulfide.  Controlled movement of reactants and reaction product gases through the system is achieved without requiring mechanical flow control equipment in any of the relatively high temperature zones approaching sul-fiding reaction temperatures or sulfur vaporizing temperature. Requirements for on-site storage of toxic and explosive hydrogen sulfide are eliminated.  The separately-fired sulfur vaporizer provides for circulation of sulfur and/or steam, without feedstock reductant gas in various production stand-by modes, which make production on demand readily available.

Abstract: A VOICE-ACTUATED SWITCHING SYSTEM          Abstract A voice-actuated switching system selectively connects multiple microphones to an audio line in accordance with the output signal levels from each of the microphones.  Comparison circuitry including an analog multiplexer, a nonlinear amplifier, an analog demultiplexer, a peak detector, an analog multiplexer, an analog to digital connecter and a centrol processing unit determines the state of each microphone which can exist in one of three states: selected, mixed, or off.  The microphone with the greatest output signal level at any given time is considered in the selected state and is selected for connecting to the audio line with no loss.  Those microphones in the mixed state have their output signal levels attenuated before being connected to the audio line. And those microphones in the off state have their outputs essentially disconnected from the audio line.  The user of a microphone which is in the mixed state can be heard along with the user of a microphone which is in the selected state, but at a lower level.  Improved accuracy is obtained in the microphone selection process by comparing the microphone signals to each other and to a reference level that takes into account any offsets induced into the signals by the system.  The system can accommodate any number of microphones.

Abstract: Abstract Ice Detector An ice detector to detect a layer of ice on a thin solid sheet (14), such as the skin of an aircraft wing, even in the presence of water, comprises two ultrasonic transducers attached to the sheet.  The first transducer (10) is adapted to cause propagation of ultrasonic waves through the sheet (14) having their predominant component parallel to the surface of the sheet (14).  Such waves will dissipate energy into an ice layer adhering to the surface, but not into air or a liquid layer.  The second transducer (30) is adapted to detect the waves propagating in the sheet and to give a signal representative of their amplitude. A discriminator (34) responsive to the signal detects the presence of an ice layer on the surface.

Abstract: ABSTRACT:         A television receiver for receiving scrambled television signals has an arrangement which provides scrambled vision components (V) and packet arranged sound/data components (D) some of which are also scrambled. The components (D) are applied to a packet demultiplexer where the packets are assembled from the data in several lines in the signal to provide a first output (P) the respective packets carrying sound/data information and at a second output (E) encrypted control data which is applied to a sub-system to produce a vision scrambling control word (VS) for each line of the vision components.  The sub-system during each line produces further bits which are applied to a descrambling control word generator which assembles these further bits from three lines to form a packet scrambling control word.  This control word and the packets associated with it are added in an adder and applied to a main packet buffer store from which each packet is read out by a packet selector and the packet is applied to a packet descrambler whilst the packet scrambl-ing control word is selected by a register and used to control the generation of a binary sequence by a pseudo random binary sequence generator which sequence is added to the packet in the descrambler, modulo-two, to achieve descrambling.  A packet identifier examines the packet address to ensure the packet requires descrambling and inhibits the generator should descrambling not be required. With such a receiver the control data (E) can be used for controlling descrambling of both the vision and the sound/ data components.
