Title: Fm stereophonic system incorporating companding of  difference signal
Inventor: TORICK EMIL L
IPC: H04H20/88
Filed: 1984-03-12
Granted: 1987-04-14
Abstract: ABSTRACT           An FM stereophonic radio broadcasting system in which stereophonically related audio frequency source signals L and R are matrixed to obtain stereophonic sum and difference signals M and S, respectively.  At the transmitter, the difference signal is compressed, and the conventional difference signal and compressed differ-ence signals modulate respective quadrature-related sub-carriers of the same frequency to develop two double-side band, suppressed-carrier signals, the frequency of the sub-carriers being sufficiently high as to assure a frequency gap between the lower sidebands of the modulated sub-carrier signals and the sum signal M.  The M signal, the aforementioned suppressed-carrier signals, and a pilot signal having a frequency which lies within the frequency gap, are combined and frequency-modulated onto a high frequency carrier for the purpose of transmitting the same to one or more remote receivers.  The receiver includes an expander for complementarily expanding the received compressed difference signal, and the expanded noise reduced difference signal is combined with the received sum signal to reproduce the audio frequency source signals L and R.  The system increases the broadcast coverage area over that of current biphonic service yet is compat-ible with existing monophonic and biphonic receivers.

Abstract: MANUALLY OPERABLE GEARSHIFT  MECHANISM                  Abstract of the Disclosure An improved manually operable gearshift mechanism is disclosed for an automobile transmission, and which gearshift mechanism is of the character including a support of sheet metal construction and first and second gear selector members mounted on the support for pivotal movement of the members to-gether about a first axis and for pivotal movement of one of the members relative to the other about a second axis transverse to the first axis.  An operating lever is attached to the second gear selector member to facilitate pivoting the first and second members about the first and second axes and between a plurality of positions relative to the support and each other and in which positions the gear selector members operate to position corresponding gear shifting cables in positions corresponding to one of a plurality of selectable transmission gears.  Im-provements are provided with respect to the structure of the support, mechanical interconnections by which pivotal move-ment of one of the gear selector members is translated to linear displacement of the corresponding gearshifting cable, stability of the gear selector members during pivotal move-ments thereof, and lockout mechanisms for preventing uninten-tional displacement of the gear selector members into the positions thereof corresponding to the reverse gear of the transmission.

Abstract: MEDICAL TABLE     ABSTRACT       A medical table which can be used for examina-tion of the spine and for other diagnostic and therapeu-tic back procedures, including discography and surgery, and which can be adapted for use with imaging devices, has a bottom support frame, a front support frame resting on the front of the bottom support frame, and a rear sup-port frame resting on the bottom support frame.  The front and rear support frames are spaced from each other to provide a substantial clearance for imaging devices including radiographic and fluoroscopic apparatus.  A radiolucent top panel is supported at one end by the front support frame and at the other end by the rear sup-port frame.  The use of front and rear support frames rather than side support frames eliminates radiopaque ma-terial adjacent to the top panel and permits oblique, la-teral, as well as anterioposterior views to be taken.

Abstract: ABSTRACT OF THE DISCLOSURE      A catalyst assembly  effective for selective catalytic reduction of nitrogen oxides with ammonia in a gas stream has an upstream section comprising a phosphorus getter comprised of a phosphorus retaining material, e.g., activated alumina, and a downstream section comprising a vanadium oxide containing cata-lyst, e.g., a vanadia/titania catalyst.  It has surprisingly been found that vanadium oxide catalysts are poisoned by phosphorus which may be contained in the form of phosphorus contaminant compounds in the gas to be treated, so that the positioning of a phosphorus-retaining material upstream of the catalyst pro-longs catalyst life.  In operation, the gas to be treated is passed first through the phosphorus getter upstream section of the catalyst assembly   and then contacted in the presence of ammonia with the downstream section catalytic material.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and an apparatus in a plant for fibrating mineral molten material which in the form of a stream of molten material is discharged to the peripheral surface of a primary spinner wheel and which is formed to mineral fibres by being thrown out from the spinner wheel or from several cooperating spinner wheels.  The distribution of the stream of molten mat-erial over the width or length of the primary spinner wheel is improved in that the force is applied to the incoming stream of molten material, especially from the rear side thereof as seen in the rotation direction of the spinner wheel, which force is act-ing in a plane substantially perpendicular to a generatrics to the peripheral surface of the spinner wheel and in a blunt angle to the stream of molten material.  The force acts on a stream of molten material a short distance in advance of the place where the material comes into contact with the spinner wheel, and the force provides a widening of the stream of molten material without breaking same up into small fragments.  The force may be provided by a gas flow or by different mechanical deflector means.

Abstract: Abstract of the Disclosure Fluid Operated System Control Controlling arrangements for controlling the amount of fluid flow deliverable from a pump to a work system tend to be complex, waste substantial amounts of energy, are costly, and operate inefficiently due to the inability to provide the proper amount of fluid flow.  A control having a primary work system, a secondary work system, a first fluid flow generating system, and a second fluid flow generating system is provided.  A control signal delivering device is provided to deliver a control signal having a magnitude responsive to a relative location of a control valve between a first and second position of a control valve.  A control signal receiving device receives the control signal and separately controls the flow rate deliverable from the first and second flow generating system in response to the magnitude of the control signal received.  The control signal receiving device has a set point value which is representative of a preselected magnitude of the received control signal The second fluid flow generating system is controlled to deliver fluid only in response to the magnitude of the received control signal having a value greater than the set point and at a substantially constant preselected deliverable flow rate.  The first flow generating system is controlled to deliver fluid at a rate responsive to the magnitude of the received control signal and, during periods at which the received control signal has a value greater than the set point, reduces the fluid flow deliverability rate of the first flow generating system, an amount substantially equal to the flow rate being delivered by the second flow generating system.  Therefore, the problems of cost, inefficiency, controllability and the like are eliminated.  The control is particularly suited for use in the fluid operated system of a material handling vehicle.
