A falling plate sensitometer for testing photographic materials comprises a shutter which allows the passage of light for a pre -set period controlled by a timer, the opening and closing of the shutter both being effected by the falling under gravity of a body from rest, the time lapse between the time initiating the opening of the shutter and the shutter allowing the passage of light being equal to the time lapse between the timer initiating the closing of the shutter and the shutter ceasing to allow the passage of light. As shown, a light proof metal case 18 has blades 13 and 14 provided with openings 19 and 20, such that on drop of blade 13 exposure is started and on drop of blade 14 exposure is terminated. Electromagnets 1 and 2 controlled by the timer, causes release of the blades 13, 14 respectively; steel springs 7 dampen their impact on the bedplate. On the front of case 18 is a wedge and filter holding frame 21, Fig. 7, having a pressure pad for film strips held in front of a slit 10 during exposure to a lamp (not shown). The blades 13, 14, Fig.1, are returned to their upper position by a handle 6 which also raises a baffle 4. In another embodiment, a shutter blade (46) Fig.10 (not shown) has an aperture (44) larger than an exposure slit (50) in a casing (40), the blade (46) being released by a hook (41) to drop on to a hook (42) for the required exposure time.

Abstract: 1356324 Testing apparatus for a memory array INTERNATIONAL BUSINESS MACHINES CORP 27 Aug 1971 [30 Sept 1970] 40278/71 Heading G4C Apparatus for testing an integrated circuit data store includes a programmed computer having a test pattern loaded in its memory, an interface which communicates with the computer, a pulse generator responsive to words in the test pattern read out through the interface to generate test stimuli, a probe connected to the generator output and adapted to feed the stimuli to a data store under test and to feed the store responses to a discriminator which in response to the store output and to words in the test pattern generates a pass/fail signal. General.-The memory chip 10 is connected to probe 11 which in turn is connected to pulse generator 15, discriminator 21, and digital to analogue converter 14. The D-A converter provides bias voltages for the memory and for the pulse generator and discriminator. A master strobe unit generates triggering pulses for the pulse generator and discriminator, in the latter case via controlled delay 23a. The computer 32 communicates with the remainder of the test system via interface 19 and is also connected to a printer 36 which prints out a representation of the results of a diagnostic program test on the pass/fail signals received from the discriminator. Test procedure.-The test pattern followed includes writing a 1 into each cell to initialize the system; reading a 1, writing a 0, reading a 0, and writing a 1 into each cell; reading a 1, and writing a 0 into each cell; reading a 0, writing a 1, reading a 1 and writing a 0 into each cell; and reading a 0, and writing a 1 into each cell. The procedure enables the following faults to be detected; cells stuck at either 1 or 0; multiple addressing, i.e. more than one cell responding to an address; disturbs, i.e., an operation on one cell disturbs the data stored in another; and bit recovery, i.e. failure to read a cell which stores a particular datum properly when all other cells in that row store the opposite datum. Further details.-A memory having an access time of 6 nsecs may be tested by a computer having a 2À2 Ásec cycle time. The memory may be activated for 6 nsecs beginning at T 1  and ending at T 2  during a machine cycle for a single write operation, or for 12 nsecs beginning at T 1  and ending at T 3  for associated write and read operations, or for 6 nsecs beginning at T 2  and ending at T 3  for a single read operation. Various circuits for use in the discriminator, pulse generator, delay element &c. are briefly described, the discriminator including a tunnel diode.

Abstract: <PICT:1080775/C6-C7/1> Spheres of 100-1000 micron diameter of material having a high melting point e.g. uranium, uranium carbide and oxide are formed by melting the material in ingot or powder form in an argon plasma furnace and subjecting the liquid as it forms to centrifugal force whereby droplets are ejected into a controlled inert atmosphere in which the solidify.  As shown the plasma furnace comprises a cylindrical working chamber 1 having double, liquid cooled walls 1a, 1b and slightly curved ends 5, 6 through which extend axially a plasma burner 2 (see Division H5) and a rotatable spindle 3 supporting a container 26 in which the material is carried. The chamber has observation windows 74, an air lock for extracting samples and may have an orifice for passing through a handling gripper.  The burner comprising a conical, tungsten cathode and an anode, both water cooled, is supplied with argon which ionizes to form plasma which is ejected through orifice 8 to form a flame 40-150mm long which impinges on the material in the container, its base 26 being of copper.  The spindle, comprising five concentric tubes forming two separate water cooled circuits, is rotatably mounted on a slide 18 permitting axial movement, in addition the inner tubes slide axially to maintain constant the distance between the burner and the face of the material in the container. The chamber is first evacuated by a vacuum pump 17, then during operation, with the spindle rotating at 2000 r.p.m. the atmosphere is maintained oxygen free and slightly above atmospheric pressure by the incoming Argon which exhausts through a pipe 12 containing a heat exchanger 14.  In a modification the material in powder form entrained in argon is introduced into the plasma by injecting it into the burner upstream of the orifice 8.  The material then impinges on to the bottom 26 of the container which rotates and ejects droplets.  The furnace may be arranged vertically with the burner at the top.ALSO:Spheres of 100-1000 micron diameter of uranium carbide are formed (see Div. B5) in an argon plasma furnace (see Div. F4) by heating a mixture of uranium oxide and carbon, melting the resultant carbide and subjecting the liquid to centrifugal force whereby droplets are ejected into an inert oxygen free atmosphere in which they solidify.
