Abstract: METHOD AND APPARATUS FOR CONTROLLING     WHEEL SLIP ON DIFFERENTIALLY-DRIVEN WHEELS                      Abstract A standard motor vehicle having a pair of driving wheels powered by a drive shaft through a differential can experience difficulties when one of the two differentially driven wheels loses traction.          The differential directs all of the power to the wheel that is slipping and the wheel with traction remains stationary.  Various anti-spin devices have been developed but these often produce an abrupt transfer of all of the driving power to the wheel having traction.          The anti-spin apparatus of this invention overcomes this problem and includes an electrical control circuit and sensors for generating a slip signal representing the speed difference between the wheels.  The apparatus further includes a modulated hydraulic reducing valve for actuating the brake on the faster rotating wheel and a hydraulic modulating control valve connected to the reducing valve and actuated by the slip signal.          The reducing valve is modulated to proportionally vary the braking force applied to the faster rotating wheel in accordance with the difference in rotational speeds between the wheels.

Abstract: RADIATION SWITCH FOR PHOTOFLASH UNIT .                 ABSTRACT OF THE DISCLOSURE    A photoflash unit having a plurality of flashlamps mounted on a printed circuit board containing circuitry for sequentially igniting the flashlamps in response to successive firing pulses applied thereto.  The circuitry includes a plurality of solid-state switches capable of being activated by radiant energy generated during flashing of lamps located adjacent to respective switches. Initially each of the switches has a resistance sufficiently high to provide an open circuit to the applied firing pulses, and after being activated by radiation, the switch undergoes chemical con-version to a conductive state over a finite time interval.  The switches are prepared from compositions comprising admixtures of silver carbonate and/or silver oxide, silver-coated glass beads and a binder; the admixtures may also include electrically non-conductive particulate solids, such as titanium dioxide, and/or silver-coated metal beads.  The constituents and proportions of the switch compi-tions are selected to provide a predetermined conversion time of twelve milliseconds or greater, thereby permitting reliable functioning with comparatively long duration, low voltage firing pulses.

Abstract: A B S T R A C T     Device and process for operation of open baking furnaces, in particular such ring-type furnaces for manufacturing anodes for the aluminum electrolytic process, are such that for each so called fire the sealing chamber and/or chamber in the cooling zone can be saved in that the flue gas exhaust mani-fold is not situated on the headwall but instead on the flue (11), and/or the opening (36) of that headwall (25) on which the last fresh air supply manifold is situated is closed off by a sliding baffle (51). Openings (34) corresponding in cross section to that of the connected part of the flue gas exhaust manifold (40) are provided in the region of the flues (11,12,13,14).     The advantage of the process lies in the greater flexibility in furnace operation, which results either in an increase in production or an increase in product quality.     (Fig. 1)
