Abstract: PHB 33.107             11 ABSTRACT:           A battery economising circuit for use with one or more operating circuits, for example a part or parts of a radio circuit, in which battery economising circuit an opposed current mirror type of current reference cir-cuit (18) determines entirely the current consumed by the operating circuit (10).  A control circuit (22) is con-nected to a point in the reference circuit (18) from which current can be extracted.  The control circuit (22) in response to an OFF signal causes a portion of the current in the reference circuit (18) to be diverted so that the reference circuit (18) cannot sustain its normal ON-state and in response thereto assumes its OFF-state in which the operating and control circuits (10,22) do not take current. The control (22) further includes means whereby current can be injected into the current reference circuit (18) to cause it to assume its ON state and in consequence the operating circuit (10) takes current.  In the case of there being several current reference circuits (18,18') and associated control circuits (22,22'), but the inputs (24,24') of the control circuits (22,22') are all connected to a common signalling bus (26).

Abstract: ABSTRACT        In a television receiver with a digital processing system for processing display parameters, a CRT discharge detector produces a signal in response to discharge of the cathode ray tube of the television receiver, and a control-reset circuit employs a signal for generating one or more reset pulses for holding the registers of the signal processing circuits in their reset state for the duration of the cathode ray tube discharge.  Following termination of the discharge, the reset signal is removed which allows the signal processing circuits to resume their normal function with unaltered data.

Abstract: QUEUE ADMINISTRATION METHOD AND APPARATUS          Abstract:         A memory subcontroller of a computer includes a queue for storing read and write requests issued by memory using units to a memory, apparatus for executing requests on the memory, and a circuit for administering the queue.          When the queue is empty and the executing apparatus is ready to receive a request for execution, a request incoming from a using unit bypasses the queue:  it is received by the executing apparatus directly and is not stored in the queue.  Otherwise, the queue administration circuit stores the request in the queue and then awaits results of validity checks on the stored request.  If the request is found to be invalid, generally the administration circuit discards the request from the queue by freeing the queue location or locations that store the invalid request to store the next received request.  The invalid request is then overwritten by the next received request.

Abstract: METHODS AND APPARATUS FOR PURIFYING INERT GAS STREAMS     Abstract of the Disclosure An inert gas stream containing parts per million levels of impurities such as O2, CO, CO2, H2, H2O, is purified by passing the same sequentially through a first bed and second bed of material.  In the first bed, carbon monoxide and hydrogen are both reacted with oxygen to form CO2 and H2O.  The latter is retained in this first bed while the reaction products and the inert gas stream are supplied to a second of material which is comprised of a getter.  In this bed, oxygen reacts with the getter material and carbon dioxide is adsorbed therein so that the inert gas stream leaving the second bed is substantially free of such impurities.  The first and second beds of material operate at temperatures up to about 38°C and these materials may be regenerated by heating the same to approximately 200°C and purging such beds with a purge gas flow.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus  for generating a plurality of electromagnetic signals, primarily optical signals, having linewidths centred on frequencies fixed relatively to a reference frequency is described.  The apparatus comprises a reference frequency signal source such as a gas laser which generates a reference signal having a frequency fp. This reference signal is fed to a leading one of a plurality of optical fibre ring lasers connected together in series by optical fibres.   The characteristics of the injected signal and the form of the waveguide ring defined by the ring laser is such that stimulated Brillouin scattering occurs in the waveguide ring to generate a scattered signal with a frequency fp-fA travelling in an opposite direction to the injected signal.   This scattered signal is passed by the optical fibres via an isolation device to the next ring laser in series.   Directional couplers are provided to guide the injected signals,  including the reference signal to respective output ports.   The stimulated Brillouin scattering effect causes each scattered wave to be offset from the corresponding injected wave by a fixed frequency FA.

Abstract: Abstract of the Invention Object Sensing Arrangement An arrangement for sensing an object relative to the side of a vehicle requires physical contact between the arrangement and the object.  Therefore, mechanically operated object sensing arrangements are prone to damage, frequent malfunctions, and premature failure.  An object sensing arrangement for identifying an object within a preselected minimum distance spaced from a first side of a vehicle has first reflective target movably connected to the first side at a location on the first side adjacent a first end portion, and a first connecting apparatus movably connects a first signaling apparatus to the first side at a first location on the first side adjacent a frame second end portion.  The first signaling apparatus delivers a first signal to the first reflective target and receives a reflection of the first delivered signal from the first reflective target.  The first connecting apparatus is movable in a direction toward the first side and in a passing relationship with the first side in response to an external force being applied to the first connecting apparatus.  Therefore, the aforementioned problems related to damage caused by physical contact and the like are alleviated.  The object sensing arrangement is particularly suited for use on a material handling vehicle.

Abstract: A dry particulate sulphite-containing material produced in a flue gas desulphurisation process is oxidized and agglomerated in a fluidised bed, wherein the material is fluidised in an oxygen-containing gas. The oxygen- containing gas which is supplied to the fluidised bed has a temperature below the agglomeration temperature of said particulate material. Due to the exothermic character of the oxidation, the temperature of the fluidised bed is maintained above the agglomeration temperature of the particulate material. Gas with entrained particles leaving the fluidised bed is cooled during its passing through the freeboard of the fluidised bed reactor, whereby problems due to sticking of said entrained particles are avoided. At least a part of said entrained particles are recycled to the fluidised bed reactor. A fluidised bed reactor is disclosed suitable for performing the combined oxidation and agglomeration.

Abstract: It is known that in ventilation systems having a plurality of air intake valves it is possible to arrange for a selective opening of valve plates in these valves between closed and fully open position, such that the opening is adjusted to the requirements. The selective opening is based on the valve plates being drawn to open through a direct pull and through a 2:1 pulley block pull, respectively. According to the invention it is possible to arrange for other transfer ratios, viz. in that a part of the opening of selected valves is effected with a transfer ratio of 2:1, while later during the opening this ratio is changed into 1:1 by way of an abutment (28) on the pulling wire (10) engaging the wire eye (12) on the valve plate (4) which, otherwise, holds the wire in a sliding manner. Hereby the total opening characteristic of the valves can be determined in a widely optimized manner in the single stable.

The laminate has a high rate of water vapour transmission, thus providing a comfortable garment, blocks transmission of bacteria and submicron size particles, sheds particles, and does not itself form particles. The laminate comprises a layer of porous polymeric film adhesively bonded by a conductive adhesive to a textile fabric layer. The preferred porous polymeric film is of expanded polytetrafluoroethylene. The preferred adhesive is a solvent ased isocyanate-cured polyester adhesive containing electrically conductive carbon particles in sufficient amount to render the composite as a whole static electric charge dissipative.
