Abstract: ABSTRACT          A disc brake boot seal 10 (and method for assembling  a disc brake system) that is molded in its extended condition and that when moved into its col-lapsed condition will remain in its collapsed con-dition.  The boot seal comprises a molded elasto-meric sleeve 12 having a plurality of different wall portions 20-34 certain ones of which interact to releasably hold the sleeve in its collapsed condition so that it does not self-extend.  The expense and high mold breakage resulting from the prior art system of molding a seal in its collapsed, convoluted condition are eliminated by this invention.

Abstract: Abstract of the Disclosure A PCM signal processing circuit records a predeter-mined number of PCM signals and also parity signals and a CRC signal after conversion into a signal having a data format conforming to the television signal with a VTR and detects the PCM signals from the reproduced signal from the VTR.  In this PCM signal processing circuit, when the preset bit number of the PCM signals is greater than a reference bit number, the number of parity signals is reduced, and extra bit portions of the individual PCM signals are allotted to the vacant parity signal slot obtained as a result of the reduction of the parity signal number.

Abstract: AUTOMATIC IM DISTORTION   TEST SELECTOR                         Abstract An  intermodulation  test  analyzer  which  auto-matically determines whether an SMPTE or CCIF inter-modulation test  is  being conducted and switches its output accordingly is disclosed. This is accomplished by  sensing  the  low  frequency  energy  content of the test  signal.  This  energy  content  is  compared  to  a reference  level  representative  of  the  low  frequency energy content of a typical SMPTE test signal. There-fore, if the low frequency energy content of the input signal is greater than the reference level, the signal is treated as the SMPTE test signal. However,  if the low frequency energy content is less than the refer-ence  level,  the  signal  is processed as a CCIF test signal.

Abstract: ABSTRACT            A fan motor sequencing switch assembly is employed to effect delayed full power energization of a magnetron in a microwave oven for protecting the magnetron and energization circuit therefor against high start-up current surge and for cooling the magnetron during oven operation. The sequencing switch is connected in parallel with a start circuit consisting of a start switch and serially connected current limiting resistor, and is operated by an actuator movable by the magnetic field induced in the fan motor upon energization, the motor being connected to the start switch and sequencing switch for energization through either switch. In the preferred embodiment, the actuator is the rotor of the motor which is mounted for rotation and limited axial movement with respect to the motor stator and normally biased to a position with its magnetic center axially displaced from that of the stator, whereby upon energization of the motor, the rotor is caused to move axially by the induced magnetic forces in the rotor and stator to effect delayed actuation of the sequencing switch.

Abstract: Disclosure 245-77-0100 ABSTRACT OF THE DISCLOSURE A controller (Figures 1, 2) is provided in a dual servo system that drives a controlled element (22) with mechanically coupled first and second servos (24 and 44).  This controller has a first (10, 110, 112) and second (14, 108, 114) digital processing subsystem.  The first digital processing subsystem can simultaneously drive the first and second servos.  This first processing subsystem is operable to measure the responsiveness of the servos to the first processing subsystem and  provide a self-checking indication.  The second digital processing subsystem measures the responsiveness of these servos to the first digital processing subsystem and can provide an independent indication of failure.  The fore-going can be extended to multiple channels for controlling independent multiple elements such as aircraft control surfaces.  Preferably, two different types of computers (10, 14; 108, 110, 112, 114) with different programs can be employed to control three control channels.  Since the system can provide self-checking and independent checking of its operation, the likelihood of "multi-axis hardover" is reduced.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to the safety of ammuni-tions.       The projectile of a cartridge has a base which houses a safety stop consisting of a transversely slidable valve. A device ensures that the valve cannot be released until the projectile has been subjected to a powerful acceleration. Another safety device very advantageously ensures that the pyrotechnical chain inserted in the base functions only when the pressure of the ejection charge has been able to release a scaling-block.       In particular, the invention may be applied to infra red window releasing cartridges.

Abstract: SCANNING BEAM OPTICAL POSITION DETERMINING APPARATUS AND METHOD     Abstract of the Disclosure A method and apparatus for determining the location of a target surface by projecting a periodically scanning pattern of light onto the target surface, and comparing the time of projection of a predetermined point of the pattern along a predetermined path with the time of observing an image of the predetermined point of the pattern reflected along an intersecting receiver path.  An apertured disc is rotated between a light source and a collimating projection lens assembly to produce scanning pattern of light.  Photoelectric sensors generate reference and receiver electrical signals in response to projection and reception of the pattern of light, and the distance of the target surface from a reference loca-tion may be electrically determined as a geometrically defined function of the phase angle between the electrical signals.          In one embodiment of the apparatus, the scanning pattern of light is both projected and received through a single projection lens, permitting the angular separation between the projection path and the receiver path to be kept small, permitting measurement of a wide range of locations of the target surface within a phase angle variation of less than 360 degrees.

Abstract: ABSTRACT OF DISCLOSURE: A motor-fan unit for a wet pick-up type of vacuum cleaner comprising a fan-section and a separately ventilated motor section.  A motor-end bracket in the motor housing structure serves as a common end wall  with the fan section and carries a bearing for the common shaft of the motor and fan.  A baffle carried by the motor-end bracket within the fan section has an apertured central portion, at least partly enclosing the bearing, to provide a passage-way for high velocity air sealing the bearing from detergent-containing cleaning liquid entrained in working air drawn into the fan section.  A normally closed check valve at an inlet to the sealing air passageway inhibits back-flow of either air or liquid through the inlet but permits such sealing air to serve as cooling air when the entrance of working air into the fan section is impeded.
