Abstract: ELECTRONIC FLASH UNIT FOR CAMERAS   ADAPTED TO RECEIVE FLASHBULBS                 ABSTRACT OF THE DISCLOSURE           An electronic flash unit for use with cameras having a flash lamp firing mechanism adapted to fire flash lamps in timed relation with the operation of a camera shutter.  An electronic time delay circuit coupled to the flash lamp firing mechanism energizes a flash unit trigger circuit to fire the flashtube in synchronism with the camera shutter.  A voltage-sensitive switching element renders the delay circuit operative once the flash unit firing capacitor is charged above a predetermined level.         With this arrangement, the flash-firing mechanism cannot energize the flashtube trigger circuit when there is insufficient firing capacitor voltage.

Abstract: ABSTRACT         For cutting extrudate catalyst supports to uniform length, a rapidly spinning roller is spaced at a set length in front of the extrusion die.  As the extrudate emerges from the die it contacts the spinning roller which causes the extruded length to shear off at the die face.  As more extrudate continues to emerge from the die it again reaches the roller and is again sheared off to the same length.

Abstract: TITLE OF THE INVENTION Transmission for Tractors ABSTRACT OF THE DISCLOSURE           A speed change mechanism for a transmission com-prises a main shaft provided with a plurality of power trans-mitting gears, and a propelling speed change gear system and a young takeoff speed change gear system supported on the opposite sides of the main shaft in parallel thereto. Each of the propelling and power takeoff speed change systems includes a speed change shaft freely rotatably carrying a suitable number of speed change gears meshing with the power transmitting gears on the main shaft at all times.  The speed change shaft accommodates an axially slidable speed change rod which, when moved, forces pins outward or inward radially of the shaft to couple the speed change shaft to the corresponding speed change gear or disconnect the shaft from the gear.  The freely rotatable speed change gears are held against axial movement, while axially slidable engaging members which are otherwise provided between the adjacent speed change gears are eliminated.  The transmission therefore has a shortened axial length and does not require a clutch which must be usually provided between the engine and the main shaft.  The propelling speed change system further incorporates a creeping assembly of the planetary roller type for super-speed reduction and is provided with a secon-dary speed change assembly.  The transmission also includes a power takeoff assembly for driving the front wheels of the tractor utilizing the secondary speed change assembly.

Abstract: HEATER SHUTDOWN CIRCUIT     ABSTRACT OF THE DISCLOSURE     The heater shutdown circuit is connected between an electric current source and a heating element in an electric heater and is operable to shut off the flow of current to the heating element when the heating element reaches a predetermined temperature and to maintain the flow of current shut off after the heating element cools to a temperature below the predetermined temperature.  The heater shutdown circuit will maintain the electric current shut off until the heater shutdown circuit is disconnected from the current source for a predetermined period of time after which the heater shutdown circuit can be re-energized.  The heater shutdown circuit includes a control circuit connected to the current source, a switching circuit coupled between the control circuit and the heating element and a current sensing circuit coupled between the heating element and the junction between the control circuit and the switching circuit.  It is operative in response to a decrease in current caused by an increase in the resistance of the heating element due to the overheating thereof to turn off the switching circuit.          The control circuit is operative to turn on the switching circuit upon the initial energization of the shutdown circuit.          Thereafter the control circuit reaches a steady-state condition where it is no longer operative to maintain the switching circuit turned on.  However, subsequent to the turning on of the switching circuit by the control circuit, the current sensing circuit latches the switching circuit in a turned on condition until there is a decrease in the current through the heating element below a predetermined value.

Abstract: ABSTRACT OF THE DISCLOSURE       An electro-optic detector utilizes a trigger circuit to sense the presence of a fluid medium and produce a control signal at a predetermined time after the fluid medium is detected.          The trigger circuit responds to the presence of a fluid medium and provides a signal to control a device external to the circuit.          The circuit includes means for producing a first signal when the fluid medium is detected and means responsive to the first signal for producing a control signal.  In one embodiment of the invention, the first signal producing means includes a light source positioned at one end of a light path, a light responsive means positioned at the opposite end of the light path and a hollow prism intermediate the light path.  When the prism is immersed in water, light from the light source is transmitted to the light responsive means which produces the first signal. The control signal producing means includes a first time delay network which closes a first gate circuit a predetermined time after the occurrence of the first signal and a second time delay network which closes a second gate circuit a predetermined time after the operation of the first gate circuit.  Closing the second gate circuit produces the control signal which is utilized in an external device.  One such external device is an automatic harness release.

Abstract: INTERNAL DIVISION ACTUATION OF VENTILATED FLOPPY DISK STACK                 ABSTRACT OF THE DISCLOSURE    A hollow tubular actuator device operates through an enclosure formed by aligned holes in multiple floppy type storage disks.  The disks, separated by interposed ventila-ting spacers, are clamped between inflexible end plates in a closely spaced continually rotating stack assembly.  The actuator preferably rotates with the stack and translates axially relative to the disks and spacers.  The actuator has a slotted opening for transmitting variable pressure to a selected spacer (address) in the stack and thereby varies the aggregate pressure equilibrium in the stack due to centrifugal air flow.  This acts to deflect the orbits of disks peripherally, on either side of the selected address space, forming a gap useful for obtaining external access to otherwise inaccessible storage surfaces adjacent the selected space.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of manufacturing sealed thermostats or the like is disclosed in which male and female members are assembled with an interference fit to produce a seal which is maintained through a predetermined operating temperature range.  The minimum interference during assembly is selected so that such minimum interference is greater than the difference in the temperature during assembly and the most adverse seal temperature to be en-countered within the temperature range, times the difference in coefficients of thermal expansion and contraction between the members times the linear dimension of the seal.  In addition, the two members are selected so that the maximum total elastic deformation is greater than the difference in coefficient of thermal expansion and contraction times the difference between the maximum and minimum temperatures within the temperature range times the linear dimension.          Preferably, the interference is selected so that the female member is stressed beyond its elastic limit, at least when the device is cycled throughout the temperature range to produce a mechanical interlocking of the two parts. The assembly of the device may also be arranged to provide calibration and/or gauging of the device.
