Filed: 1959-09-08
Abstract: 861,040. Photographic apparatus and film unit therefor. INTERNATIONAL POLAROID CORPORATION. Sept. 8, 1959, No. 30652/59. Class 98(1) The apparatus comprises a housing having an exposure chamber, means for mounting the film unit therein, a member to engage and partially remove a portion of a flexible sheet of the film unit, and a mechanism to rotate and translationally move the member in engagement with the sheet in a plane parallel to the image plane to uncover a photosensitive layer on movement in one direction and return the sheet on movement in the other direction. The film unit as indicated has a removable or cover sheet over a photosensitive layer, which is mounted on a base, a thin under sheet attached at its ends to the under surface of the base, and a draw tab arranged to slide along between the thin under sheet and the base. It may also have a rupturable container of processing fluid between base and cover sheet and the latter may carry a strip of iron adapted to magnetic attraction. A plurality of the film units in a casing may constitute a film pack. In a preferred embodiment the apparatus is a folding camera shown, Fig. 8, in open position with front section 14 at 45 degrees to rear section 16, and containing lens 32 over one of the film units 22 biased forwardly into the focal plane by pressure plate 26 and leaf spring 28, bellows 34 being provided to exclude light; rear section :16 can, however, accommodate the film pack, the casing of which may be withdrawn to leave the individual units therein. In operation, not here fully described, opening of front section 14 preparatory to exposure draws steel tape 120 forwardly to cause translational movement of carriage 108 on tracks 104 and also rotation of magnetic spool 112 on the carriage, whereby engagement of the spool with the iron strip of the cover sheet unrolls the latter, permitting exposure of the underlying sensitive surface, after which closing of forward section 14 causes reverse operation, and with the cover sheet protecting the sensitive surface the unit may be withdrawn by tab 24a between pressure rolls 42, 48 and out of the camera, to cause rupture of a container (not shown) and spreading of the fluid, normally with production of a positive image on the underside of the cover sheet which latter may, finally, be removed from the remainder of the film unit.

Abstract: 622,924. Measurement of short time intervals. MARCONI INSTRUMENTS, Ltd., PITMAN, D. A., COE, P. S., and HUNT, E. W. Nov. 15, 1945, No. 30666. [Class 37] [Also in Group XL (c)] A short interval of time is measured by synchronizing a charge integrator with the beginning of the interval, synchronizing a similar integrator with its ending and measuring the phase difference between the two generators, the charge integrators receiving periodically recurrent small increments of charge. General operation.-Oscillations from OSC, Fig. 4, are applied to integrating generators IDU, IDL, each producing a stepped oscillation. The impulse ST, Fig. 3, at the start of. the interval is applied to IDU to discharge the integrating condenser and synchronize the stepped oscillation IDU<SP>1</SP> with the pulse ST. Similarly, the impulse SP occurring at the end of the interval is applied to IDL to synchronize the stepped oscillation IDL<SP>1</SP>, Fig. 3, with SP. Oscillation IDU<SP>1</SP> is applied to the X plates of a cathode-ray tube CRT to give a time base, and a pulse corresponding to the end of the cycle IDL<SP>1</SP> is applied to the Y plates to give a " blip " MP<SP>1</SP>, whose position on the time base indicates the magnitude of the interval. Pulses corresponding to the end of each cycle of oscillation IDU<SP>1</SP> may be passed on to further integrating generators IDU2, IDL2, Fig. 5, started and stopped by the impulses defining the interval so as to measure periods greater than the time of one cycle of IDU<SP>1</SP>. Further oscillators IDU3, IDL3 and IDU4, IDL4 may be similarly used. Integrating generators.-Oscillations from OSC are applied to the grid of valve V1, Fig. 6, so that positive pulses appear in the anode circuit corresponding to negative half-cycles from OSC. These positive pulses charge condensers C1, C2 ; condenser Cl discharges through diode V2 when valve V has the positive half-cycles from OSC applied to its grid, but condenser C2 cannot discharge and receives increments until it renders valve V5 conducting which renders valve V6 non- conducting and the positive pulse developed in the anode circuit of V6 is applied to render valve V4 conducting to discharge condenser C2. The synchronizing pulse is applied to diode V7 to render V5 conducting. The time base potential is taken from the cathode of cathode follower V9, and the marker pulse is obtained from a multivibrator fed from the screen of valve V6, Fig. 7 (not shown). Pulses for integrating in succeeding stages are taken from the anode of valve V5.

Abstract: <PICT:0391865/III/1> <PICT:0391865/III/2> <PICT:0391865/III/3> <PICT:0391865/III/4> p  Water is treated by means of a device consisting of a container and a body within it which produces an electric discharge by frictional action as a consequence of the agitation of the container.  Hard water so treated yields a loose deposit when heated.  The device may consist of a glass bulb containing mercury and neon or other gas or mixture of gases having no reaction with mercury, the gas being under a low pressure, for example under 40 mm. of mercury.  The water is preferably treated in an earthed metal tank.  The glass bulb 10, Fig. 1, contains mercury and is carried by loops 18 of a wire 16 which is also looped around a vertical wire 22 fixed to a heavy base 24.  When the tank in which this device is situated is filled with water and emptied, the bulb is caused to rise and fall and to swing around the wire 22.  The device may comprise two bulbs connected by a tube through which the mercury passes to and fro.  Devices 28 of this kind are used in the forms of apparatus shown in Figs. 4, 5 and 6.  As shown in Fig. 4, two devices 10 move respectively on the upright members of a wire frame 27 fixed to a heavy base 25.  The devices 10 are connected by a wire 29 carrying a drum 33 and two devices 28.  A cord 35 is wound on the drum but has its ends fixed to the base 25 and to a cross wire at the top.  The arrangement is such that as the devices 10 move up and down, with the water level, the devices 28 are turned about the wire 29.  The drum 33 may be replaced by a toothed wheel meshing with a fixed rack.  As shown in Fig. 5, devices 28 and paddle blades 34 are fixed to the same horizontal shaft and rotated by water passing through a vessel 15.
