Title: Improvements in or relating to x-ray apparatus
IPC: G21K1/02
Filed: 1949-05-02
Abstract: 665,730. X-ray apparatus. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. May 2, 1949 [May 29, 1948], No. 8287/51. Divided out of 665,692. Class 98 (i). [Also in Group XXXIV] In apparatus including a Bucky diaphragm mounted to move longitudinally in a table, means are provided for preventing undesired movement of the diaphragm while permitting desired longitudinal adjustment thereof, said means comprising a bracket secured to one end of the diaphragm, a crank with an unlocking segment carried by its shaft mounted in the bracket, a pinion pivoted on the shaft and carrying an unlocking segment, a coil spring encircling, and with radial end portions disposed between, the segments and frictionally housed in the bracket, and a rack mounted on the table and engaged by the pinion, whereby turning the crank in either direction acts on one of the ends of the spring which is thereby released to allow movement of the diaphragm, while the diaphragm is locked against unintentional movement by the springs binding in its housing and being made tighter if the locking segment presses on an end portion thereof. As shown, the carrier 22 for the Bucky diaphragm, which may also carry photographic material in a cassette, is longitudinally movable on rails mounted in an X-ray table 21, which may be of the kind described in Specification 665,692. The carrier is moved by a handle 141 journalled in a bracket 129 fixed to the carrier, which drives a pinion meshing with a rack 138 fixed lengthwise to the table. The shaft 132 of the handle has a semi-circular segment 136. The pinion (not shown) has a similar segment 135 attached thereto and is freely mounted on shaft 132. Segments 135, 136 are surrounded by a coil spring 137, the ends of which are turned between the segments, and which is contained in a circular recess 140 in the bracket 129. Should the carrier 22 tend to move of itself, the pinion will tend to turn and the segment 135 will press one end of spring 137. This will tend to open the spring and press it against the housing 140, increasing the frictional resistance to movement. If handle 141 is turned, however, segment 136 presses one end of the spring to reduce its diameter, reducing friction until movement takes place. A roller 139 may be mounted on bracket 129 to engage the lower edge of rack 138. Specification 665,729 also is referred to.

Title: Improvements in and relating to apparatus for recording the accuracy of gun practiceat moving objects
IPC: F41G3/26
Filed: 1919-04-02
Abstract: 137,443. Jepson, W. April 2, 1919. Teaching gunnery.-Relates to target-practice apparatus in which a miniature target is mounted on the gun and is caused to move relatively thereto in an irnegular manner, and consists (1) in mounting the entire apparatus on the gun, (2) in moving the target to bring it back into the line of sight by means actuated from the gun as it is made to follow the target, (3) in employing a dotter to record the. accuracy of the shots, and a liner to record the closeness of the following movement, and (4) in combining with the apparatus a bullet-box, and an aiming-rifle mounted on the gun. In the form shown, the target card is carried in a frame 1 movable (a) vertically in a frame 2 swung on links 5 pivoted to an horizontal part of the frame 6, and (b) horizontally on a roller 8 engaging a member 4 swung on similar links pivoted to a vertical part of the frame. Irregular to-and-fro motion is imparted to the card by a cord 13 secured at one end to the frame 2 and at the other to a pin 14, and passing over pulleys 16 mounted eccentrically on shafts driven by clock-work 17, the motion of the pulleys being preferably regulatable as regards phase and speed. Irregular up-and-down motion is similarly applied by a cord 18 actuating the member 4, the same pulleys being preferably employed. The gun is caused, during the training movement, to displace the card in a direction contrary to that of the horizontal movement produoed by clock-work, by means of a device comprising a cord 20 anchored to the ship or other structure and passing round a spring-controlled drum 21, the consequential movement of which is caused, through reduction gearing, to displace the pin 14 and therefore also the frame 2. The distance of the pin 14 from the gear-pivot 25 may he adjusted in order to simulate the effect of firing at different ranges. A similar device is employed to cause the elevation of the gun to impart a compensating vertical movement to the card through the member 4. If the gun is made to follow the target accurately, the movement of the target due to the clock-work 17 is exactly compensated by the movement of the target due to the gun; any difference between the two movements may be recorded continuously on the back of the card by a liner 27 of known construction. A dotter 28, also of known construction, marks the card when the gun is fired. Another dotter may be provided in conjunction with a travelling band for recording the intervals between shots. Two synchronously-moving target-cards may be employed for convenience in sighting, only one card receiving records. Alternatively to the dotter and liner mechanism, a bullet-box may be set up behind the target-card, upon which actual shots may then be fired by an aiming-rifle mounted on the gun.

Title: Synthetic crystalline zeolite
IPC: C01B39/02
Filed: 1959-03-11
Abstract: A synthetic crystalline zeolitic molecular sieve of formula 0,9\sB0,2Na2O:Al2O3: 4,6-5,9SiO2: 6-7 H2O, designated zeolite S and having a specified characteristic X-ray diffraction pattern, is prepared by maintaining a sodium alumino-silicate/water mixture of composition given below, at 80 DEG  to 120 DEG C. under a pressure at least equivalent to the water vapour pressure, until crystals are formed.  The aluminosilicate/water starting mixture may be prepared from sodium aluminate and alkali, and a source of silica, which may be sodium silicate or an aqueous colloidal silicate sol. If sodium silicate provides the silica, the initial mixture, on an oxide mole ratio basis, has a composition such that Na2O/SiO2 is 0,5, SiO2 Al2O3 is 25 and H2O/Na2O is 18.  If colloidal silica sol. is used, the ratios may be 0,3 to 0,59, 6 to 9,99 and 20 to 100 respectively.  The formed crystals are preferably washed until the effluent pH is 10 to 11.  Such crystals are generally 2 to 5 microns in diameter and have a density of 2,08 gms./c.c.  For use as an adsorbent for gases, the crystals are dehydrated at 350 DEG C. under vacuum.  The adsorption capacity of the dehydrated zeolite for water, argon, krypton, CO2, N2, C3H8, C3H6, C6H6, NH3, SO2, O2, and n-pentane is compared.  The zeolite may be pelleted with clay.

Abstract: N-vinyl- and N-(substituted vinyl)-2-oxazolidones of formula <FORM:0893689/IV (b)/1> where R1, R2, R3, R4 and R5 may be the same or different and may be hydrogen, alkyl, aryl or aralkyl are prepared by heating (e.g. at 200 DEG C.-300 DEG C.) an oxazolidone-aldehyde condensation product of formula <FORM:0893689/IV (b)/2> where R is a primary alkyl or aralkyl radical [for preparation see Specification 887,595] at reduced pressure (e.g. below 100 mm. Hg.) either alone or in the presence of an acid catalyst of low volatility to give a 2-oxazolidone and an N-vinyl- or N-(substituted vinyl)-2-oxazolidone and rapidly removing the products from the reaction mixture and separating them from each other.  Preferred catalysts are Lewis acids having a low vapour pressure up to 300 DEG C., e.g. ZnCl2, AlCl3, e.g. in amounts of 0.05%-5% by weight of starting material.  The reaction products may be distilled and condensed and the N-vinyl compound removed from the 2-oxazolidone by washing with a poor solvent for the latter.  A mixture of starting material and catalyst may be heated, or the liquid starting material added to hot catalyst, or the vapourised starting material may be passed through a heated bed of catalyst on a carrier.  The molten mixture of starting material and catalyst may be passed quickly through a heated zone from which the products are rapidly distilled.  The catalyst may be dissolved in fused 2-oxazolidone before the starting material is added.  The presence of a finely divided copper is desirable; this may be added as such or as decomposable copper compounds, e.g. cupric acetate or oxide.  The examples describe the preparation of N-vinyl - 2 - oxazolidone, N - propenyl - 2 - oxazo - lidone and N-vinyl-5-methyl-2-oxazolidone; N-styryl-2-oxazolidone is also mentioned.  Reference has been directed by the Comptroller to Specification 851,773.

Abstract: 545,284. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc., and HILLIER, A. May 17, 1940, No. 8812. Addition to 492,670. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 21, 1940.] [Class 97 (iii)] The gyroscopic apparatus claimed in the parent Specification is modified by mounting the polyphase stator directly upon a member from which a sensitive element of the gyroscope is supported with freedom to precess, and mounting the conductive member (co-operating with the stator) on the sensitive element. As shown in Fig. 3, wherein the gyro casing 71 is universally mounted by a gimbal ring 6, a conductive cup 81 is carried by a stem 191 depending from the gyro casing. Stator poles 11<SP>1</SP> are mounted on a fixed base 35 and are supplied with three phase current by way of connection-reversing relays controlled by pendulums 36, 37 co-operating with reversing contacts 39, 391, 40, 40<SP>1</SP>, the pendulums being pivoted about the two gimbal axes. The magnetic flux across the poles of the stator is varied in direction by the pendulums according to the tilt of the rotor axis and the eddy currents consequently induced in the conductor cup 8<SP>1</SP> produce a reactive torque to eliminate the tilt. A more graduated control may be obtained by making the pendulums form the sliding contacts of potentiometers in a Wheatstone bridge arrangement supplying the stator pole windings. In a modification applied to a "slave" directional gyroscope, Fig. 4, wherein the gyro rotor spins on an horizontal axis 51, and the rotor casing 41 pivots about an horizontal axis 42 in a verticallypivoted ring 43, a cylindrical conductive member 46 is secured to the rotor case and torque is applied thereto by a three-fingered stator 1111 mounted on the vertical ring. The torque is applied in either direction by reversing one of the phases of the three-phase windings by means of a reversing switch 47, Fig. 6, which may be operated manually or from a remote magnetic compass or other control means.
