Title: Improvements in and relating to viscosimeters
IPC: G01N11/06
Filed: 1933-03-22
Abstract: 400,840. Viscosimeters. GLASPLAKATEFABRIK UNION GES., 86, Hardtstrasse, Karlsruhe, Germany. March 22, 1933, Nos. 8669, 8670, and 8671. Convention dates, March 24, 1932. July 28, 1932, and Feb. 22, 1933. [Class 106 (ii).] Comprises a vessel provided with two marks and a vertical capillary d connected therewith, in which the capillary terminates in a widened outflow tube e which communicates with the atmosphere by means of a branch tube i. The vessel a connected to the top of the capillary d is connected to a pipe g open to the atmosphere, the pipe i being connected to the pipe g. A vessel l connected to the tube or vessel e also communicates by a pipe h with the atmosphere. In use, the apparatus is filled with liquid to the level A-A<1> and then by suction on the pipe g or pressure on the pipe h the liquid is drawn up through the capillary to the level B-B<1>. The suction is now released, and the liquid in the pipe i immediately drops back, opening the vessel e to the atmosphere. The liquid at the lower end of the tube d then takes on a curved surface, shown in dotted lines. The time taken for the liquid to fall back enables the viscosity to be calculated. If it is not desired for liquid to rise in the tube i the pipe i is continued to the same level as the pipe g and a tap is provided at the top which is closed during suction and opened during the timing of the fall of liquid in the capillary. A tap connected by a short pipe to the bend at the hottom of the apparatus facilitates changing the liquid. In a modification, the vessel l is made of metal and the pipe h and the tube below the vessel e dip into it. In a. further modification the join between the capillary d and the vessel e is given a flat annular surface at right-angles to the capillary. The height of liquid remaining in the capillary and supported by the plane film of liquid across the annulus is a measure of the surface tension.

Title: Magnetic data storage system
IPC: G11C11/15
Filed: 1965-03-01
Abstract: 1,064,623. Magnetic storage devices. SPERRY RAND CORPORATION. March 1, 1965 [March 31, 1964], No. 8726/65. Heading H1T. [Also in Division H3] A magnetic information storage device comprises an anisotropic thin magnetic film member 10 (Fig. 4), in which information is stored, adjacent a second film member 12 of similar magnetic and physical characteristics, the two film members being arranged with their easy axes parallel and the direction of remanent magnetism in 12 being dependent on the direction of stored remanent magnetism in 10 so that the latter can be read out non-destructively by disturbing the former. Each film member may be formed of a plurality of thin layers having single domain properties. Information is written into 10 by overlapping pulses (52), (54) (Fig. 5, not shown) in orthogonal write conductors 48, 50 (Fig. 4) remanent magnetism being also produced in 12 in a direction opposite to that in 10. The magnetism in 12 (but not in 10) is disturbed by the transverse field produced by a read pulse in the series connected conductors 42, 44 and an output indicating the information stored in 10 is produced in conductors 40, 46. Several other arrangements incorporating conductive ground planes are described (Figs. 9, 12 and 15, not shown) in one of which (Fig. 9, not shown) the direction of remanent magnetism in the read-out magnetic film element is turned anti-parallel to that already written into the information storing magnetic element by the combination of the cross field produced by a pulse in the interrogation conductor and the longitudinal field produced by the remanent magnetism written into the information storing magnetic element. In another such arrangement (Fig. 12, not shown) the magnetic film elements (10), (12) are arranged adjacent opposite sides of a conductive ground plane (94) which shields the information magnetic film from the read-out field. In a further such arrangement (Figs. 15 and 16, not shown) long-duration orthogonal write pulses having gently sloping leading and trailing edges are used to reduce the distorting effect of a ground plane (110) on the drive fields influencing the read-out and information magnetic films (10), (12) while a rectangular interrogation pulse is used to maximize the effect of (110) on the interrogation flux density in the area of read-out core (12). A word-organized memory array is described consisting of sixteen of the storage devices described above with reference to Fig. 3 (Fig. 17, not shown). In this array the bits constituting a word are written in simultaneously using individual information pulses for the devices involved and a common overlapping cross field pulse. The bits forming the word are also read out simultaneously by a common crossfield read pulse which disturbs the read-out magnetic films of the devices involved, the outputs produced being coupled to sense amplifiers (S/A) connected to a register of bi-stable flip flops which provides temporary storage.

Abstract: 520,323. Pile fabrics. DU PONT DE NEMOURS & CO., E. I. March 18, 1939, No. 8734. Convention date, July 28, 1938. [Class 142 (iv)] The fabric is composed, especially the pile thereof, wholly or in part of one or more synthetic linear polyamides. These may be used for the pile yarns, the ground warps or the ground wefts or all of these, and the polyamide fibres may be obtained by condensation of monoaminocarboxylic acids or by the reaction of diamines With dibasic carboxylic acids. Crimped polyamide fibres may be used. The pile fabric may be woven face to face on a double shuttle loom, or by means of wires or by terry weaving or as weft pile fabrics, or by sewing or attaching fibres to a backing, or as chenille fabrics. The fibres may be set by treatment with steam, hot water, methanol and ethanol, hot aniline. Various examples of the weaving of pile fabrics on a double shuttle loom are given. The polyamide fibres may be set in the condition or position ultimately desired, for instance uniformly inclined, or disarranged throughout or in portions of the fabric, by treatment with steam, hot water, alcohols or hot benzine. Delustred fibres, colour fibres, fibres containing plasticizers, wetting agents and hygroscopic materials may be used. Shrunk or unshrunk filaments may be used for the pile. The fabric may be sized &e. Fibres of various sizes and lengths, crimped and curly forms of the fibre or tapered filaments may be used. Spontaneously crimpable polyamide filaments such as described in Specification 514,821 may be used and the weaving of these and subsequent treatment of the fibre, including cutting the pile when wet is described. Unmoistened synthetic polyamide filaments may be used as pile elements and be cold drawn after weaving. A part only of the pile elements may be cold drawn thus producing pile of intermingled short and long filaments of the same or different cross-section. Polyhexamethylene adipamide may be used. The weaving of pile fabrics with all the yarns of polyhexamethylene adipamide, and also with the latter pile yarns and ground yarns of cotton on a double shuttle loom is described and also the prior treatment of the ground yarns with hot air of a specified moistness before coning, and the subsequent treatment of the fabric. Also the weaving of a pile fabric with yarns of polyhexamethylene adipamide viscose pile and cellulose acetate.

Title: Improvements in Chronotelemetrical Apparatus for use in Regulating the Firing of Anti-aircraft Guns.
IPC: F41G5/08
Filed: 1917-06-18
Abstract: 127,351. Maison BrÚguet, and Routin J. L. Oct. 20, 1916, [Convention date] Addition to 127,280. Speed indicators operating by sighting aerial objects; velocity components, measuring. - Consists in modifying the anti-aircraft gunnery apparatus described in the parent Specification by utilizing the sighting-telescopes of the gun as the telescopes of the speed measuring apparatus, the corrections in these telescopes being effected directly without taking readings. The invention involves a modification of the apparatus for graphically determining the product of the angular speed and the time of flight. The drawing shows only the apparatus for measuring and correcting for the zenithal angular speed. The sight L is mounted on the gun cradle, and is elevated with it. The elevating-gear, operated by the handle A, is connected through differential gear D to a screw V which traverses a fork B in which is mounted a rotating drum C. The drum C is rotated at a regular speed by clockwork and is marked by a fixed stylus F so that a curve of the angle of site in time functions is produced. A pointer F-G, pivoted at F, is set tangential to this curve by operating a screw H which is adjustably mounted so that its distance above the point F can be made proportional to the time of flight, thus the number of turns given to the screw H counting from the position in which F-G is vertical, measures the product of the angular speed and the time of flight. This product is the required sighting correction, and it is applied to the sight by a flexible shaft K. The screw H is connected by bevel gearing to the differential gear D to ensure that the transversing movement of the drum C is proportional to the movement of the sight in space.

Title: Dialysis apparatus
Inventor: GREENING JOHN RAYMOND
IPC: B01D61/46
Filed: 1958-03-19
Abstract: Dialysis tubes 7, which are normally of glass but can be of any suitable material, are open at one end and being closed at that end by a leakproof stopper 9.  The semi-permeable membrane is in the form of a sac or bag 10, formed from a length of tube, one end p  being closed by knotting, the other end being similarly closed after insertion of a specimen.  A measured amount of the specimen is put in the sac or bag, any air is excluded by squeezing together the walls of the membrane, the sac or bag to allow movement of the specimen and also for any expansion of the specimen which may occur.  A measured amount of another fluid is then placed in a dialysis tube 7 and the sac or bag inserted, the stopper 9 closing the end of the tube.  The requisite number of dialysis tubes are thus charged and attached to the drum 3 by the spring clips 6, the motor started and the drum rotated.  The free space in the dialysis tube above the dialysis fluid ensures the movement of the dialysis fluid within the dialysis tube.  This movement in turn enhances the movement of the sac or bag within the dialysis tube which would otherwise only occur by virtue of the difference in density between the dialysis fluid and the specimen.  This enhanced movement of the sac or bag also increases the motion of the specimen in relation to the inner surface of the sac or bag.  A modified form of the apparatus suitable for continuous or periodic flow of either or both of the liquids without stopping the drum is also described.

Abstract: 1427667 Control of a number of A.C. motors GOODYEAR TIRE & RUBBER CO 27 Feb 1974 [26 March 1973 23 July 1973] 8969/74 Heading H2J In a vehicle conveying system of the type comprising spaced vehicles which traverse high speed zones between stations and low speed zones through stations, each vehicle 12 is decelerated from the high to the low speed by engaging it with an appropriate number of wheels 22 each driven by a respective polyphase synchronous or induction motor 24a, 24b, 24c ... which motors are sequentially connected to the same one of three ramp-generator/inverters 26, 28, 30 as the vehicle advances through the deceleration section of the low speed zone, the inverter progressively reducing the frequency of supply to the motors to correspondingly reduce the vehicle speed. If the vehicles are part of a passenger conveying system wherein each vehicle is decelerated to and accelerated from the speed of a station moving platform, Fig. 1 (not shown), the motors 24a, 24b, 24c are of synchronous type to maintain the vehicle spacing and are respectively controlled by vehicle-operated switches 36a, 36b, 36c ... , stepping switches 32a, 32b, 32c ... and stator control switches SA, SB, SC. In a typical operation, switch 36a is closed by the vehicle to step switch 32a to position A and so cause closure of switches SA to connect the motor 24a to the inverter 26, the motors 24b, 24c ... being similarly energized by closure of switches 36b, 36c ... as the vehicle 12 advances. By the time another vehicle 12 enters the deceleration section, the previous vehicle has progressed sufficiently to allow the switches 36a, 36b, 36c... to be operated by the new vehicle to step the switches 32a, 32b, 32c ... round to position B and so sequentially connect the motors to the inverter 28, the subsequent arrival of a third vehicle completing the cycle by stepping switches 32a, 32b, 32c to position C to connect the motors to the inverter 30. The arrangement operates so that each motor is varied over a limited speed range according to its position within the section, closure of switches 36a, 36b, 36c ... connecting each motor to the inverter to raise its speed to that of the approaching vehicle. Members 36, 32 and SA, SB, SC may be replaced by circuits each comprising a sensor controlling a logic arrangement operating triac switches connecting each motor to the inverters, Fig. 5 (not shown). The layout of a full deceleration section is described, Fig. 2 (not shown), acceleration of the vehicles being produced in a similar manner. Wheels 22 may be replaced by rollers, drums or belts.

Abstract: 1457323 Typewriters TRIUMPH WERKE NURNBERG AG 27 Feb 1974 [2 March 1973] 8983/74 Heading B6F A key input to a typewriter comprises keylevers 2 associated with control members 10 which when actuated release drive levers 17, to permit a respective drive lever to coact with a constantly rotated drive roll 27 whereby the drive lever is displaced to displace a respective combination of setting rockers 20. Depression of a keylever 2 pivots its associated control member 10 about axis 11 whereby a projection 16 on the respective drive lever 17 is released from a holding recess 15 to permit a spring 25 to pivot the lever 17 so that a cam 26 thereon contacts the drive roll 27. A flat 28 on the cam loosely detents the cam in its rest position shown. On powered displacement of the lever 17, a respective combination of setting rockers 20 and a further rocker 31 are displaced. The rocker 31 pivots a blocking bail 33 which prevents other drive levers from being actuated. If the key lever is depressed only so far that a projection 34 thereon strikes a stop 35, repeat power action is prevented since the tripping pawl 5 on the keylever is out of alignment with the projection 8 on the control member when the control member returns. However on further depression of the keylever, rocking the rail 36 carrying the stop 35, against the action of a spring 37, a projection 9 on the control lever 10 becomes operative and repeat action occurs. Under the latter circumstances, a bail 40 is displaced to act as an additional interlock.
