Title: Improvements in or relating to the filtration of liquids
IPC: B01D29/00
Filed: 1924-12-09
Abstract: 227,094. General Engineering Co., (Assignees of Genter, A. L.). Jan. 2, 1924, [Convention date]. Filters having sheet filtering-materials. - In the filtration of hot liquids or liquids containing gases by means of suction filters, the suction is continued for short periods only with short alternating periods of liquid counter-pressure for cleansing the medium, the separation of gas of vapour in the filtrate spaces being thus reduced. Filter elements 10 are suspended in radial frames 30 in a tank 12<1> to which the liquid to be filtered is supplied by a pipe 13<1>. The filtrate is discharged from the elements 10' through the frames 30, outlets 31, radial ports 33 and a casting 15' to a receiver 19<1> connected by a pipe 20' to a vacuum pump and condenser. Within the casting 15<1> is a rotary plug 16<1> adapted to cut off the communication of one or more of the ports 33 with the receiver and to open communication of the ports so cut off through passages 35 in the plug to a reservoir 26<1> which contains filtrate, for the cleansing counterflow. The filtrate is drawn from he receiver 19<1> through a pipe 21<1> connected by a branch with the reservoir 26'. The plug 16<1> is driven by a pawl and ratchet wheel, the pawl being given a quick forward motion with slower return.

Title: Improvements in or relating to shock absorbing devices
Inventor: HATFIELD JOHN EDWARD
IPC: B64D1/14
Filed: 1959-09-01
Abstract: 905,836. Energy-absorbing devices. IRVING AIR CHUTE OF GREAT BRITAIN Ltd. June 29, 1960 [Sept. 1, 1959], No. 29826/59. Class 103 (1). In an energy-absorbing device for use when a moving load is suddenly arrested or retarded, e.g. in the case of falling loads being braked by parachutes, the device comprises a housing, a member slidably disposed with respect to the housing, a sheet of material being located in or on the housing which progressively severed or sheared by a divergent head portion on the slidable member when the latter is moved with respect to the housing. In the embodiment disclosed, one end 12 of the energy-absorbing device is coupled by means of straps, cables or the like to the load for which the device is required and the other end is attached to the movement arresting that device, e.g. the lift web of a parachute. The energy-absorbing device includes a housing composed of three plates 1, 2 and 3 secured together in sandwich by means of screws 4; plates 1 and 2 being provided with recesses 7 and 8 on the faces of the housing to accommodate shear strips 9, 10 of suitable metal. When assembled together the plates form a slideaway for a slidable member 11 having a divergent wedge-like head 14 which overlies the planes of the shear strips 9 and 10 so that on outward movement of the slidable member, strips 9 and 10 are progressively stripped to absorb the kinetic energy. The shear strips may be of uniform thickness throughout their length so that the kinetic energy dissipated when the shearing action takes place will be of a uniform nature or, alternatively, the strips may be of tapered section so that the load required to bring about shearing will progressively increase or decrease during outward movement of the slidable member.

Title: Aqueous asphalt emulsions for use as agricultural mulches
IPC: C08L95/00
Filed: 1962-08-03
Abstract: Aqueous asphalt emulsions for use as agricultural mulches are prepared by emulsifying 1-10% (by weight, of the asphalt) of an organic solvent of boiling point 100-500  DEG F. with an asphalt of initial hardness greater than 70 penetration at 77  DEG F., thereby reducing the hardness of the asphalt to a maximum of 61/70 penetration at 77  DEG F., before, during or after forming the aqueous emulsion.  The emulsion preferably contains 20-60% by weight of asphalt.  Suitable solvents include various naphthas.  Emulsifiers utilizable may be cationic-including primary, secondary, tertiary or poly-amines or salts thereof, such as <FORM:0989384/B1-B2/1> where R is a 6-18 carbon alkyl chain; such amines combined with 1-10 mol parts of ethylene oxide; quaternary ammonium salts; aromatic and cyclic amines and salts thereof; Z-imidazoline -or anionic, e.g. R COONa where R is an 8-22 carbon alkyl chain; or salts of pine wood lignin or resins-or fine clays, e.g. bentonite.  These agents are usually present as salts formed in the emulsifying solution, and various acids and bases may be used for this purpose, e.g. HCl, CH3COOH, HNO3 or NaOH, KOH.  The emulsions may be prepared in conventional mills.  A typical emulsion contains asphalt (c. 50%), 400  DEG F. end-point naphtha (2-5%), N-alkyl trimethylene diamine (0,2-0,4%, and 36% HCl (0,1-0,3%), and water.

Title: Improvements in or relating to gyro-verticals or gyroscopic artificial horizon instruments
IPC: G01C19/44
Filed: 1945-11-12
Abstract: 615,734. Electric control systems. SPERRY GYROSCOPE CO., Inc. Nov. 12, 1945, No. 30255. Convention date, Nov. 11, 1944. [Class 40 (i)] [Also in Group XX] A gyrovertical or gyroscopic artificial horizon instrument having a gravity responsitive control device is provided with means for modifying the control effect exerted by the control device due to Coriolis acceleration forces acting thereon when a craft carrying the instrument moves relative to the earth's surface. Additional means may be provided for modifying the control effect exerted by the control device due to horizontal acceleration forces acting on it when the craft turns. As shown, the rotor casing 3, Fig. 1, pivots about an axis 4 in a fork 5 integral with a horizontal shaft 6 pivoting on bearings 7, 8. A Y-shaped bracket 12 carrying a pendulum bob 11 is similarly pivoted in a fork 13 mounted on bearings 14, 15. An electromagnet in the bob 11 co-operates with a saucer-shaped conductor 75 on an extension of the rotor spin axis to provide an electromagnetic erecting torque on the gyro, whenever the latter and the pendulum are out of alignment. The correcting torques are applied by the induction motor 16, 70 to the fork 13 so as to prevent deflection of the pendulum by Coriolis effects and centrifugal force on turning. One phase from a two-phase generator 21, Fig. 2, is fed to one winding 16 of the motor, the second phase being supplied to the primary 22 of a transformer, the secondary coil 23 of which is rotated manually or from an air speed motor so that the secondary voltage is proportional to the velocity v. The latter is then fed to the primary 25 of a transformer, the secondary 26 of which is rotated through the angle of latitude L. The secondary voltage, proportional to v sin L, is then transmitted to the second winding 17 of the motor. The angular setting of the secondary 26 may be effected manually by the knob 27 or automatically by the constant speed motor 28 which drives a roller 30 on the shaft of the knob 27 through the friction disc 29 and two balls in a cage 31. The radial distance of the cage 31 from the centre of the disc 29 may be adjusted manually by the knob 32. An additional torque to correct for centrifugal force is supplied by a winding 18 wound in the same slots as the winding 17 and supplied through the variable transformer 68, 69, which is adjusted by the constrained gyro 60, with a voltage proportional to the product of the velocity and the rate of turn. In a modification, the gyro is erected by two torque motors acting respectively on the pitch and roll axes and controlled by contacts in a liquid level carried on the rotor casing. In this case the motor acting on the pitch' axis is provided with an additional winding to which voltages proportional to the desired corrections are supplied. Specification 552,554, [Group XX], is referred to.
