Abstract: ABSTRACT              This invention relates to a multiple glazing assembly of the type made from metal extrusions such as aluminum.  A pair of main frame members are connected by insulating members arranged to separate the frame members to provide a thermal break and also to give a triple seal to prevent air entering between the panes of the glazing.          The frame members are shaped and the insulating members are arranged so that a pair of such insulating members resists movement in one direction transverse to the axes of the metal extrusions.  The third insulating member resists movement in a direction different to such one direction so that the insulating members combine to lock the metal extrusions against relative movement otherwise than an axial direction.          A resilient tube is particularly suitable for use as the third insulating member.  The connection thus provided has the further advantage of flexibility to withstand impacts and deviations from linearity of the metal extrusions.

Abstract: Title    :   RADIALLY CURVED AXIAL CROSSECTIONS    OF TIPS AND SIDES OF DIFFUSER VANES.                  Inventor :   Kenneth Campbell ABSTRACT           This invention is proposed further to increase the effi-ciency of all vaned diffuser types used in centrifugal compressors, without in itself further increasing the overall diameter.  The invention is so to curve in radial plane, the axial crossections of vanes from tip to near the throat, so as logically to accommo-date the heretofore deleterious effect of the long-recognized highly-arched relative velocity traverse across the impeller exit annulus, a recognition seldom reflected in diffuser structure over the past approximately 49 years of vaned diffuser development.

Abstract: METHOD OF AND MEANS FOR CONTROLLING        ELECTRICAL DEVICES                        Abstract In the control of two or more electrical devices powered by a common battery and each actuated by a separate controlled rectifier chopper circuit, at least one of which is an SCR chopper circuit, under high stress conditions requiring both electrical devices to be repeatedly and rapidly turned on and off it has been found that control over the SCR chopper circuit can be lost due to inherent inductive effects which prevent the charging of the commutating capacitor of the SCR chopper to at least full open circuit battery voltage.  This problem is met by inhibiting the occurrence of an "off" actuation control signal to the SCR chopper circuit for a given period of time before and a given period of time after an "on" actuation control signal to the other chopper circuit. Thus, in a battery powered lift truck, for example, having a drive motor and a lift pump motor each actuated by an independent SCR chopper circuit, an "on" actuation control signal to the drive motor circuit is sensed and any "off" actuation control signal to the lift pump motor circuit is inhibited for a few hundred microseconds before and a few hundred microseconds after the drive motor circuit is actuated to allow the battery to return to at least full open circuit voltage before the pump motor circuit is turned off.

Abstract: ABSTRACT OF THE DISCLOSURE     This fluid mixing valve is particularly adapted to mix steam and water to operate a liquid nozzle gun as for instance in the food processing industry to wash utensils and equipment.  This valve is adapted to be connected upstream of the gun in particular to prevent burns by the steam, to minimize the waste of steam, and to minimize the occurrence and effects of water hammers resulting from mixing steam with water.  This valve comprises a body defining a steam inlet, a water inlet, a heated water outlet, a heat exchanger connecting both inlets to the outlet, a piston chamber, and a venturi nozzle merging the chambers of the heat exchanger for flow of water under suction by the steam flow.  A valve closes the steam inlet under the action of a piston responsive to the pressure in the liquid inlet and a bleed valve and passage are arranged to bleed unintentional flow of water when the mixing valve is closed to prevent unintentional opening of the valve.

Abstract: Disclosure 245-79-0030 ABSTRACT OF THE DISCLOSURE         A control system directs an aircraft along a predetermined curvilinear descent path (10).  The aircraft carries a plurality of sensors, for example, an altitude sensor.  The system has a longitudinal device (64) responsive to at least one of these sensors for  providing a longitudinal signal related to longitudinal displacement of the  aircraft.  The system also has a height device (26) responsive to the longitudinal signal for producing a height signal functionally related to the altitude required to follow the path.  Also, a command subsystem (36) responds to the height signal and a given one of  the sensors to produce an error signal bearing a predetermined relation to the extent of deviation from the descent path.  In one embodiment dispersion otherwise occurring during a flare maneuver is reduced by definitively directing the aircraft onto a specific path such as a circular arc.  Such a control system may employ an aircraft motion monitoring system (Figure 4) having a descending subsystem (86) responsive to at least one of the aircraft sensors for producing a descent signal signifying aircraft descent rate.  Also included is an altitude differentiating device (80) for differentiating the output of the altitude sensor.  Also a transfer subsystem (98, 100) produces a signal, controlling influence in its production being transferred from the descending subsystem to the altitude differentiating device in response to arrival of the aircraft at a predetermined position.  The control system preferably employs another motion monitoring system (Figures 3 or 5) having a velocity sensing device (74, 112) providing a velocity signal signifying ground Disclosure 245-79-0030 speed and a travel integrating device (62) for integrating the output of a longitudinal acceleration sensor carried by the aircraft.  A feedback device (72) is coupled around the travel integrating device.  This feedback device has a combinational subsystem (70, 68) responsive to the longitudinal acceleration sensor and the velocity signal for driving the travel integrating device.  The foregoing motion monitoring systems can be highly reliable and can produce initial conditions which reduce transients.

Abstract: CONTINUOUSLY EXCITED LASER           ABSTRACT OF THE DISCLOSURE            There is disclosed continuously - excited lasers of the CO2 mixing, and supersonic CO, types.  There is specifically disclosed a method, and a laser apparatus, for producing a repetitively pulsed output, in which a stream of excited gas, of the type having a relatively long excitation life, is produced, stored and subsequently transferred, in the form of pulses, to a power extraction zone incorporating a resonator.  In one example the gas laser is a supersonic CO laser in which the CO is excited in the excitation zone and is, after storage, transferred under supersonic conditions to the resonator.  In the main example the gas to be excited is N2 which is initially transferred to a storage chamber provided between a rotatable storage cylinder (16) and an axial supporting shaft (18) therefor, and thereafter the N2 is transferred through holes (17) in the storage cylinder (16) which align during rotation with slots (20) through a surrounding fixed cylinder (19) to allow pulses of excited gas to be transferred to the power extraction zone (12) where it is mixed with CO2 and He, entering through supply tubes (23), and to which it transfers its excitation before flowing to the resonator.
