Abstract: ABSTRACT OF THE DISCLOSURE         A projector is disclosed which is constructed as an integral part of a wheel alignment head for use in an alignment system for the wheels supporting a vehicle chassis.  The projector causes a beam to be emitted from the "back" of the alignment head toward the supporting wheels at the opposite end of the chassis.  The projector is configured so that the direction of the projected beam relative to a reference direction may e adjusted within about plus or minus 5° of arc by turning a manually accessible adjustment knob.  The adjustment knob also causes a corresponding adjustment to a signal generator so that a signal output is obtained therefrom which is indicative of the angular departure of the beam from the referenced direction.

Abstract: ABSTRACT     METHOD AND APPARATUS FOR CONTROLLING A STEPPER MOTOR        A method and apparatus for controlling a stepper motor of a disk drive is described for;  minimisation of stepper motor oscillations for a single step, minimising the time taken for the stepper motor to move between tracks for multi-track seeks, and reduction of angular hysteresis due to the mechanical and magnetic properties of the stepper motor construction.     This control is achieved using a microprocessor-based circuit adapted to drive the stepper motor in accordance with predetermined programs.   Oscillations of the stepper motor are damped by controlling, using one program, the current applied to the stepper motor during the last step of its motion by switching this current on and off within small predetermined time intervals.   The time taken to move between tracks is controlled by another program in which the non-linear torque speed characteristics of a particular stepper motor are matched by a non-linear pulse rate which is determined by data held in the memory of the microprocessor circuit.     This data can be modified to suit the requirements of the stepper motor and load.   Another program controls minimisation of hysteresis by ensuring that each track on the disk is approached from the same direction and from the same previously energised set of windings.          The microprocessor controls the direction of motion of the stepper motor and hence decides whether or not the read/write head should cross the desired track and return it to ensure uniformity of approach.

Abstract: ABSTRACT: An electronic switch for use in the tip and ring circuit of a rotary dial telephone pulsing system is disclosed. The electronic switch is a functional replacement for a single pole, double throw electromechanical pulsing relay having normally open and normally closed output terminals, with the state of theoutput terminals being reversed in response to the connection of an external impedance load to an input sensing node. Normally open and normally closed output nodes are driven by first and second output switching circuits. The operating states of the first and second output switching circuits are reversed in response to a switching signal generated by a binary switch. The binary switch is biased off with no switching signal being produced in the absence of the external impedance load so that one output terminal is normally open and the other outputterminal is normally closed. When the external impedance load is connected to the sensing node, the switching signal is generated, thereby reversing the operating states of the output switching circuits.

Abstract: ABSTRACT OF THE DISCLOSURE     A  circuit  fuse  assembly  designed  to  prevent  damage  to consumer electronic devices due to customer misuse.   The fuse assembly  comprises  two  fuses  in  series.   The  first  fuse  is readily accessible to the user and is set to open the circuit at a current level which protects the electrical product against an overload current condition.   The second fuse is located  in a position that is normally not accessible to the customer and is set with a current rating higher than the current rating of the more accessible fuse.   Thus  if a customer replaces  the  lower current rated,  more accessible fuse, with a short circuit,  or much higher current rated fuse,  the less accessible fuse will still protect the circuit.  In addition, if the second fuse burns out it will provide a permanent record of customer misuse.

Abstract: Abstract Lasting heel seat and side portions of a shoe In a combined heel seat and side lasting machine, in which the heel seat lasting operation takes place during the dwell time necessary for the cement side lasting operation, the backpart of the shoe remains free of any clamping pressure at least in and adjacent the backseam region thereof, which pressure would have the effect of forcing excess material out of the heel seat region into the region to be lasted by the side lasting instrumentalities, while at the same time provision is made for locating the shoe, prior to the side lasting operation, in a predetermined relationship, both heightwise and lengthwise, with the heel seat lasting instrumentalities.  To this end, the shoe is first located lengthwise by the heel band (16), whereafter, with the shoe clamped against a holddown (20), the heel band is retracted out of engagement with the backseam region of the shoe during the side lasting operation.  If desired, to assist in controlling any excess material, breast line grippers (172) may be provided, in which case the heel band, in its retracted position, is caused to clamp on to the shoe to maintain the tension provided by the breast line grippers and enable them to be released prior to initiation of the side lasting operation.

Abstract: REMOTE DETECTION OF GASES IN THE ATMOSPHERE                          Abstract Gases in  the  atmosphere are  detected  remotely using a frequency mixed CO2 laser beam formed by passing the beam from a first CO2 laser through a frequency doubler  and then  frequency-adding  the output to the frequency  from  a second  CO2 laser  to obtain wavelengths in  the  3  micron region.   A first wavelength in this region, preselected for nonabsorption  by the gases to be detected,  is  transmitted through the gases toward an object capable of reflecting the beam  back.   A  second  wavelength  preselected  as  highly absorbed  by  the gases to be detected is then  transmitted.          The presence and quantity of the gases is then determined by the  difference in the amount respectively absorbed  at the two wavelengths.

Abstract: S P E C I F I C A T I O N     Title    : METHODS AND APPARATUS FOR FEEDING AND            CONTINUOUSLY CASTING MOLTEN METAL WITH INERT GAS APPLIED TO THE MOVING MOLD SURFACES AND TO THE ENTERING METAL      Inventors: R. William Hazelett Charles J. Petry Stanley W. Platek ABSTRACT OF THE DISCLOSURE        Methods and apparatus for feeding and continuously cast-ing molten metal are described in which inert gas is applied to the moving mold surfaces and to the entering metal for the protection or shrouding of the molten metal surface within the mold cavity from oxygen and other detrimental atmospheric gases.          The shrouding is by means of inert gas injected into the mold through a semi-sealing nosepiece, or directed at the mold cavity and passing through the necessary slight gaps around the nose-piece.  At the same time, such inert gas is further circulated by channeling or shielding the circulated gas for blanketing and diffusing of the inert gas along the moving mold surfaces for cleansing them of undesired accompanying gases, such as atmospheric oxygen, water vapor, sulphur dioxide, carbonic acid gas, etc. as the mold surfaces approach the nosepiece before entering the mold region.  In installations where the inert gas is directed at the mold cavity from above and/or below the nosepiece, the gas is ejected at a relatively slow flow rate so as to be noiselessly ejected, i.e. without audible disturbance, the objective being to avoid entrainment of air.   Heavier-than-air inert gas may advantageously be used above the nosepiece, while lighter-than-air inert gas is simultaneously used below it.

Abstract: Abstract A system for dynamically balancing a wheel uti-lizes low speed (preferably 50 to 100 rpm) rotation of the wheel that can if desired be provided manually . In manual operation as the rotation is imparted to the wheel by an operator, the rotational speed of the wheel is measured, and an indicator notifies the operator when sufficient rotation-al speed has been imparted to the wheel to enable a balan-cing operation to be carried out.  Thereafter the wheel is allowed to coast and decelerate until the sensed forces have adequately settled out, then the forces of imbalance trans-mitted by the rotatable shaft are measured.  When the mea-surements are obtained, any detected imbalance of the wheel is displayed on a suitable indicator mechanism.
