Abstract: ABSTRACT OF THE DISCLOSURE:           A method and a device for detecting cracks in metal pieces having a same shape and made of a same metal, for example hardened steel grinder balls. This detecting device comprises a mechanical assembly including an anvil and especially designed to produce an impact between an actually tested metal piece and the anvil, this impact generating an acoustic wave formed of a plurality of components. One of these wave components is produced by vibrations of the metal piece and has a frequency indi-cating a cracked or uncracked state of the metal piece. A microphone is provided for sensing the acoustic wave generated by the impact and for delivering a signal representative thereto. A measuring circuit receiving the signal from the microphone, and including in series an amplifier, a band-pass filter, a rectifier and an integrator, measures the energy, within a predetermined time gate and within a predetermined frequency bandwidth, of the above-mentioned one component of the generated acoustic wave, the predetermined frequency bandwidth being defined by the transmission bandwidth of the band-pass filter. Of course, the anvil is designed so that its vibrations produced by the impact generate  no wave component at a frequency included within the predetermined frequency bandwidth, whereby the crack detection is not disturbed by any acoustic wave component generated by the anvil. A logic circuit is also provided to synchronize the measure operation of the measuring circuit in accordance with the moment of occurrence of the impact between the actually tested metal piece and the anvil, and to control this measure operation. The integrated signal representative of the measured energy from the integrator is compared with a reference through a comparator which provides an output indicating if the actually tested metal piece is cracked or uncracked. The detecting device may be used in a device for sorting cracked and uncracked metal pieces, which sorting device comprises for example a deflector tube operated in accordance with the output of the comparator to deflect the cracked and uncracked metal pieces towards respective storing locations.

Abstract: ABSTRACT: "Colour display tube."         A colour display tube comprising in an evacuated envelope 1 an electron gun system 5 of the "in-line" type for generating three electron beams 6, 7, 8 situated with their axes in one plane. The axis of the central beam 7 coincides with the tube axis 9. The electron beams converge on a display screen 10 provided on a wall of the envelope and in the operating display tube they are deflected over said display screen in two mutually perpendicular direc-tions by means of a first and a second deflection field 80, 91, the direction of the first deflection field being parallel to the said plane. At its end the electron gun system comprised curved field shapers 27, 28 for causing the fields described on the display screen by the elec-tron beams to coincide as much as possible. Each field shaper comprises two or more plates 29, 30, 31, 32 of ferro-magnetic material situated substantially in the elongation of each other and separated by slots, said plates being symmetrical with respect to the said plane and the central beam axis and the curved field shapers facing the three beams with their concave sides so that the field shapers make the first deflection field at the area of the elec-tron beams pincushion-shaped. At least the plates 29, 32 which are farthest remote from the said plane comprise at their ends remote from the said plane substantially flat plates 33 extending substantially in the direction of the central electron beam. In such a colour display tube the losses in the second deflection field are small and said field is substantially not distorted. The desired pincushion-shaped distortion of the first deflection field in the field shapers is even intensified.

Abstract: AUTOMATIC SLACK ADJUSTER FOR VEHICLE BRAKES     ABSTRACT       A  slack  adjuster for  a  cam actuated brake system  is  disclosed  in  which  the  change  of angularity of the brake applying push rod relative to the  actuating arm during brake  application is used  for  sensing  stroke  length  and  effecting adjustment  to  compensate  for  brake  wear.    The adjusting mechanism comprises a pull rod and a gear rack coupled together by a lost motion connection. The lost motion distance corresponds with the normal stroke length of the brake applying push rod when the brake  linings have  the normal  clearance.   A pinion meshes with the gear rack and is coupled to an adjusting shaft through a one-way clutch.   The adjusting shaft carries a worm which drives a worm gear to reposition the actuating shaft of the brake system to compensate for brake wear.  When the brake is  applied,  any  overtravel  of  the  lost  motion represents  brake  wear  and  the  overtravel  is memorized by the position of the gear rack.   This movement of the gear rack causes the one-way clutch overrun the  shaft and  the  shaft  is not  rotated. When the brake is released, the gear rack is moved in the other direction an amount corresponding to the overtravel  and the  one-way clutch drives the adjusting shaft to reposition the actuating shaft to compensate for the brake wear.

Abstract: ABSTRACT OF THE DISCLOSURE      A method of enhancing transdermal  delivery of a pharmaceutically active drug from a transdermal delivery system as well as a transdermal delivery system capable of  providing  a  desirable  flow  interface  between  the delivery system and the skin surface are disclosed.  The method involves pre-treating an area of skin with an anticholinergic agent in an amount sufficient to have a local  antisecretory effect on the area treated,  such amount being insufficient to cause systemic effects; and applying  the  transdermal delivery  system to the pre-treated  area.   The  delivery  system  of  the  present invention is comprised of a carrier means,  a pharma-ceutically  active  drug  and  an  anticholinergic  agent. With  both  the  method  and  the  delivery  system,  the anticholinergic  agent   is  preferably  a  quaternary ammonium salt which is itself transdermally delivered to the  area beneath  the  delivery  system  in  an  amount sufficient to suppress perspiration in that area.  The suppression of perspiration prevents the formation of an aqueous interface between the skin and delivery system which might prevent drug delivery.

Abstract: TWO SPEED AXLE              Abstract of the Disclosure A low power electric motor slowly load to spring, which rapidly operates a two speed axle shift. An electric motor drives a nonreversing worm gear which engages a gear rack on a shaft.          The shaft supports a caged spring.  The motor moves the shaft, compressing the spring against one end of the cage, storing energy required for shifting.  A solenoid piston holds the cage in position.  When the shift is desired, the solenoid is tripped, the piston is raised and the spring moves the cage.  An arm on the cage moves the shift lever.  The solenoid piston engages the opposite detent in the cage and holds the cage in the new position.  As the cage arrives at the new position, a lug trips a microswitch which completes a circuit to operate the motor in the reverse direction.  The motor worm slowly drives the gear which slowly drives the rack to move the shaft in the reverse direction, compressing the spring against the opposite end of the cage.  When the shaft moves sufficiently to fully load the spring, a lug on the shaft trips the switch turning the motor off. The next pulsing of the solenoid causes the spring to drive the cage in the opposite direction, back towards its first position, where the solenoid locks the cage.  A lug in the cage trips the switch, turning the motor on to run in a forward direction, driving the shaft to its original position and compressing the spring until a lug on the shaft engages a switch, turning the motor off.
