Title: Reverse osmosis membranes
IPC: B01D71/16
Filed: 1973-01-05
Abstract: 1420122 Reverse osmosis membrane EASTMAN KODAK CO 5 Jan 1973 [6 Jan 1972] 695/73 Heading B1X [Also in Divisions B5 and C3] An asymmetric cellulose ester reverse osmosis membrane has (a) an active surface which can selectively exclude dissolved sodium chloride ions from passage therethrough under applied pressure while selectively permitting the passage of purified water; (b) an integral porous substructure immediately adjacent the active surface, the porous substructure having a substructure flux under 600 psi pressure of at least 10000 gallons of water per square foot per day; (c) from 36% to 41% combined acetyl and at least 1% combined formyl; and (d) a porosity of at least 70%. The membrane may be produced by casting a dope (see Div. C5) containing a pore-forming agent, exposing the cast film to air for from 15 to 100 seconds and then immersing it in an aqueous bath at 100 to 190F. Examples are given of the use of such membranes in desalination of water.

Title: Improvements in and relating to gear shaping machines
Inventor: BEAN ARTHUR INSLEY
IPC: B23F23/12
Filed: 1956-01-09
Abstract: 788,420. Gear-cutting. FELLOWS GEAR SHAPER CO. Jan. 9, 1956, No. 708/56. Class 83 (3). A gear-shaping machine for straight or helical, internal or external gears, comprises a reciprocating cutterspindle carrier 2, a spindle 11 coaxially mounted therein, guide means G to control the rotation of the spindle carrier and spindle and supplementary guide means 21, 24 to control the rotation of the spindle with respect to the carrier, during relief movements of the tool. The cutter carrier 2 is rotated by a worm W and is guided by engaging members G constructed according to the helical angle of the teeth. The cutter is secured by a nut on an adapter 7, which has a spherical surface 8 at its upper end to permit tilting movement, and clutch teeth 9 at its lower end which can be pulled into driving and locking engagement with teeth on the carrier 2 by an hydraulic piston 31. The supplementary guide means consists of an angularly adjustable guideway 21 on the carrier engaged by a roller 24 on the spindle so that when the spindle is moved downwardly to relieve the cutter, the cutter is given a helical motion to follow the angle of the teeth. In addition to the downward relieving movement of the piston 31, the cylinder 30 is moved laterally by pistons 43, 44 to tilt the cutter about the spherical bearing 8. The pistons work in a system operated by the movements of the spindle and carrier. A cam device 50 permits the adapter 7 to be locked when a cutter is replaced. Scales are provided to indicate the normal adjustment of the guideway 21 and of the hydraulic unit 13, which is adjusted angularly according to the helix angle of the teeth so that the tilting relief movement is in the appropriate direction. U.S.A. Specification 1,478,472 is referred to.

Title: Improvements in or relating to adding machines
IPC: G06C21/04
Filed: 1952-01-09
Abstract: 735,701. Calculating-apparatus. BRUNSVIGAMASCHINENWERKEAKT.-GES. Jan. 9, 1952 [Feb. 26, 1951], No. 724/52. Class 106 (1). The upper (alternatively the lower) orders of the totalizer and their spring-operated differential actuators 12 are adapted for item counting by the provision of a control device which is actuated by movement of any one of the remaining or amount actuators beyond zero during a machine cycle and, when so actuated, permits the actuator in the counting order to move one step. In the apparatus shown, the control device comprises a comb 19 formed with cam ends 19a to its prongs whereby the comb is rocked downwardly upon its support shaft 20 and against a spring 21 upon movement, beyond " 0 '' of any one of the seven amount actuators 12. Secured to the comb is a stop arm 18 lying opposite the actuator 12 in the counting order so as normally to arrest the actuator in the zero position (Fig. 6). When, however, the comb is rocked downwardly during entry of an item, the stop arm 18 is lowered and presents. a step 18b to the actuator which thereupon moves forwardly to enter " 1 " into the counting order of the totalizer. The mechanism is conditioned for item counting by clockwise (Fig. 2) manipulation of a control lever 23 into the position shown. A pin 32 on the lever then cams a lever 33 clockwise which, through a transverse lever 36, rocks the zero stop clear of the counting order stop bar 12. A finger 23b on the control lever 23 releases an arm 25 on the support shaft 20 of the comb 19 so permitting the comb to be raised by its spring 21 into effective position. Excessive downward movement of the stop arm 18 during item counting is prevented by engagement of an ear 31a on a lever 31 under the arm 25. When the control lever 23 is manipulated counterclockwise to inhibit item counting, a finger 23a on the control lever rocks the lever 31 to move the ear 31a clear of the arm 25, whilst the finger 23b depresses the arm to lower the comb 19 and stop arm 18 into ineffective position clear of the stop bars 12. During totaltaking operations, a shaft 29 rocks clockwise and, through a crank-arm 28 and a lever 22 spring-connected to the lever 31, again lowers the arm 25 to inhibit counting. Where a " non-add " key is provided, the lever 33 is made in two spring-connected halves and the left-hand half is depressed when the non-add key is operated so that the zero stop is restored to active position in the counting order and inhibits counting of the " non-add item.

Title: Magnetic storage of information
IPC: G11C11/06
Filed: 1964-01-08
Abstract: 1,004,932. Magnetic storage devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 8, 1964 [Jan. 11, 1963], No. 796/64. Heading H1T. [Also in Division H3] A magnetic data storage device comprises a magnetic core member having a first write conductor which when energized produces a first field resulting in a remanent flux state of given orientation in the core member, means being provided for producing another remanent flux state of the same orientation but different distribution, these means applying the first field and a smaller second field transverse to the first field and terminating after it. In the storage device shown in Fig. 1a a " 0 " is stored by a saturating pulse in conductor W alone which results in the clockwise flux distribution shown in Fig. 4a. A " 1 " is stored by applying a pulse in conductor W and a limited overlapping pulse in B which results in the different but still clockwise flux distribution shown in Fig. 5a. A saturating read-out pulse in W then produces an output in B for a " 1 " but merely a slight noise for a " 0 ". The write pulse in B is not large enough to produce any remanent flux change in the absence of a saturating pulse in W. A separate read-out conductor parallel to B may be used. Only part 12 of core member 10 or alternatively the remainder of member 10 need have appreciable flux remanence. In a magnetic memory the word conductors W 1 -W 3  (Fig. 6) may be energized for read-out, switches 16.1-16.3 and 18.1-18.3 connecting row conductors B to loads 22.

IPC: H02H7/04
Filed: 1998-01-06
Abstract: PROBLEM TO BE SOLVED: To protect a current transformer, by inputting a secondary current of a current transformer to an open circuit protecting device, comparing such secondary current with a predetermined current value to detect that the secondary circuit of the current transformer is disconnected or opened, thereby forming a short-circuiting circuit. SOLUTION: A circuit breaker 1 is closed to allow a current to flow into a main circuit 3 of three phases, a secondary current is applied to a current transformer 4 and its secondary current is inputted to an open circuit protecting device 5. The input secondary current is converted to a current value insulated by an insulation converting circuit of the open circuit protecting device 5, the converted current is inputted to a current comparison/open circuit detecting circuit. The current comparison/open circuit detecting circuit detects the opening condition of each phase, and each output relay corresponding to each phase discriminated as the open circuit is energized to terminate the broken or opened phase. As a result, burning of current transformer 4 and damage to wiring or connecting device of the secondary circuit may be prevented.
