Abstract: DATA SET DIAGNOSTIC SYSTEM            Abstract of the Disclosure A voiceband data set network includes a control data set, a plurality of tributary data sets and a diagnostic control device.  User-provided data is communicated between the control data set and the tributary data sets via a primary channel within a four-wire private telephone line.  Diagnostic and control information is communicated between the control data set and the tributaries via a secondary channel within the private line.  Diagnostic and control information is communicated between the diagnostic control device and the control data set, with which it is co-located, via a control channel. Each data set includes a data set diagnostic unit, or DDU, via which it transmits and receives the diagnostic and control information.  Communications among the DCD, DDUs, and primary controllers within the data sets, are carried out on a link-by-link basis, with the DDUs serving as message switching nodes and with communications over each link being principally comprised of requests and reads. The DCD, DDUs and primary controllers communicate in a hierarchy in which requests and reads are always directed downstream.  The tributary data sets are provided, however, with a way of directing request-type message texts upstream.

Abstract: ABSTRACT       The invention relates to a method for recovering rare metals from the combustion residues of various coals, in parti-cular brown coals.  The recovery is performed by digestion, more particularly by aqueous and/or dilute alkaline and/or dilute acidic digestion, where two or three of these steps can be combined in any desired order or they may be carried out separately.  During digestion the concentration of the solution is monitored and the subsequent digestion steps are terminated at a desired concentra-tion.  The solid and liquid phase are then separated and the rare metals are isolated from the liquid phase while the solid phase, optionally after neutralization and/or washing can be utilized for example as a source of energy.

Abstract: A b s t r a c t An apparatus for applying hot thermoplastic stripe ma-terial to a solid surface. The apparatus comprises a pipe circuit including various means for storing and circulating stripe material, an applying device for said material, as well as an electronic control unit controlling the applying device. The applying device comprises a plurality of adjoin-ing controllable gates. Each gate opening is of a width, i.e. the dimension perpendicular to the paper of Fig. 1, corresponding to a width module in the multi-stripe complex to be applied, whereas the height of the gate opening cor-responds to the thickness of the applied material. The to-tal width of the gates corresponds at least to the total width of the multi-stripe complex to be applied. Fluid-oper-ated actuating means are present on the applying device, which serve to open and close the gates quickly. In this manner a possibility of a simultaneous applying of several marking stripes in a multi-stripe complex is obtained. Fur-thermore, the width of each stripe is easy to change. In addition, it is ensured that the beginning and the ending of each stripe is clear cut.

Abstract: EXPANDABLE HYDRAULIC TAPPET WITH      A VARIABLE EXIT VALVE                   Abstract Of The Disclosure An expandable hydraulic tappet with a variable exit valve is supplied for use in an internal combustion engine to selectively vary timing by altering the effective profile of a camshaft.  The tappet expands to extend the drive train between the camshaft and a camshaft operated mechanism by enlarging and filling an internal hydraulic chamber with a noncompressible hydraulic fluid via an inlet port and inlet valve.  The fluid is retained in the tappet chamber until a pre-determined pressure is atta??ed, when an exit valve opens to exit the pressurized fluid from the chamber at a predetermined rate.  The exit valve includes a bore having a predetermined configuration to provide one or more exit flow rates and also dampen valve operation. An exit valve control means responds to the pressure within the hydraulic chamber to open and close the exit valve and vary the flow rates as desired.

Abstract: ABSTRACT OF THE DISCLOSURE           A convenient feedtube protector and single-motion cover lifting structure is provided for a food processor of the type including a housing containing an electric motor drive and control means for rendering the motor drive inoperative unless the control means are actuated.  A bowl is mountable on the housing surrounding a rotary tool which is adapted to be driven by the electric motor drive, and a removable cover with a feedtube mount-ed thereon forms a passageway for feeding food items through the cover into the bowl.  A feedtube protector is nestable in a pre-determined position around the feedtube, and this protector carries a food pusher captured in telescoping relationship which can be plunged longitudinally into the food passageway for pushing food items toward the rotary tool in the bowl.  The food processor can be actuated when and only when both the cover and the feed-tube protector are properly positioned, such that the control means become actuated to permit operation of the motor drive, thereby preventing inadvertent insertion of a hand or foreign object through the feedtube while the tool is being driven.  The feedtube protector and the cover are separate items, and there-fore the normal procedure for removing the cover from the bowl is to remove the feedtube protector first and set it down on a counter and then to remove the cover.  In accordance with the present invention, a lateral access opening is provided in the outer sleeve of the feedtube protector for exposing the feedtube to the grasp of the user.  Accordingly, when the protector is grasped with the thumb on one side and with the fingers on the other, either the thumb or the fingers press directly through the lateral access opening onto the feedtube.  Thus, when the hand is raised, the cover is automatically and simul-taneously lifted together with the feedtube protector in a single,convenient motion using one hand.

Abstract: CABLE TELEVISION TAP BRACKET OR THE LIKE                 Abstract of the Disclosure The invention contemplates a suspension bracket and clamp bent and therefore integrally formed from a single strip of metal, the clamp being completed by a nut-and-bolt fastener to compress integrally connected clamp jaws upon a desired local point of attachment to an overhead suspension cable, such as a messenger wire for support of CATV cabling or the like.  The configura-tion is such that for initial placement upon the suspen-sion cable, the jaws are downwardly open to permit effectively hooking the bracket to hang from the cable; the hanging involves bolt-shank contact with the top of the cable section and lateral retention by and between confronting inner surfaces of the jaws.  One of the jaws has an inwardly bent formation at such downward offset from the bolt shank as to establish a trapped or nested relation of the cable section when the fastener is tightened to compress the jaws upon the cable section.

Abstract: There is described a musical instrument such as a piano comprising a plurality of vibratile members such as wires capable of vibration to produce notes of selected frequencies, a hammer mechanism for each said vibratile member for causing vibration thereof, and an actuating mechanism for selectively rotating each hammer from a rest position to strike the vibratile member associated therewith and a return mechanism for rotating the hammer back to its rest position. A hammer rail is provided to support the hammer in a rest position. A control mechanism for the hammer includes a pivotally mounted adaptor having an inertial mass movable in a substantially vertically upwards direction and active upon the hammer when struck thereby to absorb the kinetic energy of the hammer moving towards the hammer rail to thereby exert a decelerative force upon the hammer. The hammer rail has a surface of resiliently deformable material such as felt which the hammer abuts in the rest position thereof. The pivotally mounted adaptor is located for striking by the hammer moving towards the hammer rail substantially at the moment of initial contact of the hammer with the felt.

Abstract: ABSTRACT OF THE DISCLOSURE         A  solid-state  load  protection  system  having electronic simulation of motor heating characteristics.  A current sensing function is utilizes so as to produce an output signal which is related to the current in an elec-trical circuit.  Attached to the current sensing function is an inverse time delay circuit and has a signal path for charging and discharging a capacitor.  The voltage across the capacitor is related to the thermal state of the load.          Depending  upon  the  voltage  across  the  capacitor,  the inverse time delay circuit which is essentially an over-current and timing function which is monitoring the volt-age will initiate either a time-out or trip sequence or a reset  sequence.   The  time before  time-out  or  reset  is proportional to the voltage across the capacitor.  An out-put function which is connected to the overcurrent and timing  function upon  receiving  a  trip  signal causes a light emitting diode to conduct and also deenergizes a contactor through which a current source is connected to the load.  Upon receiving a reset signal the output func-tion prohibits the light-emitting diode from conducting and energizes a contactor thereby connecting the current source with the load.

Abstract: MOTOR POWER FACTOR CONTROLLER WITH A       REDUCED VOLTAGE STARTER                      Abstract A power factor type motor controller in which the conventional power factor constant voltage command signal is replaced during a 5 to 30 second starting interval with a graduated control voltage.  A ramp generator 174 provides an initial ramp-like signal which replaces a constant power factor signal supplied by potentiometer 70.  The ramp-like signal is applied to terminal 40 where it is summed with an operating power factor signal from phase detectors 32, 34, and 36 to thereby obtain a control signal for ultimately controlling SCR devices 12, 14, and 16 to effect a gradual turn-on of motor 10.  The SCR devices are turned on at an advancing rate with time in response to the summed or combination signal rather than simply as a function of a ramp-like signal alone, to thereby eliminate motor instabilities.

Abstract: BLIND SHAFT DRILLING                ABSTRACT OF THE DISCLOSURE           In the mining of various minerals from the earth, large mining shafts extending from the surface down to the deposited mineral layers or seams in the earth can be provided through the use of large diameter bore hole drilling equipment.          With the drilling equipment stationed on the surface of the earth, a drilling member is drilled down into the earth for forming a shaft in excess of 10 feet to a depth of at least 2000 feet.  As the earth is broken up during the drilling operation, the broken fragments are removed from the drilled hole by a reverse circulation drilling operation.  During the drilling operation, the drilling bit is maintained in proper alignment with the shaft being drilled by the use of non-rotating stabilizers having an outer diameter substantially equal  to the diameter of the hole being drilled.  By maintaining fluid at a sufficient level in the drilled hole. during the drilling operation, an adequate hydrostatic head can be created for exerting an opposing pressure on any zone of instability on the walls of the drilled hole for-preventing inflow of water and debris.

Abstract: ABSTRACT OF THE DISCLOSURE       According to the present invention,  a thermostat for use  in  fire  detectors  is  possible  which  has  improved characteristics.  A unique electrical contact arrangement is provided  which  reduces  the  tendency  of  the  electrical contact  points  to  weld  while providing  a  simple  spring biasing to allow the  thermostat  to  return  to  its  initial position  as  the  pressure  decreases.   This  structure  is particularly useful with rate of pressure increase  sensing devices,  although it  is also useful  for fixed  temperature activation.  A greater life expectancy or ease in testing is achieved  by  providing  two  leaf  springs,  each  having  an aligned contact surface for defining an electrical contact.          The  leaf springs  simplify  adjustment  of  the  device  and reduce welding of the contact surfaces.
