Title: Improvements in or relating to air-line lubricators
Inventor: JAMES DAVID RICHARD
IPC: F16N7/34
Filed: 1959-10-13
Abstract: 868,472. Air-line oilers. WILLIAMS & JAMES (ENGINEERS) Ltd. Oct. 13, 1959, No. 34617/59. Class 12 (3). In a one-shot air-line lubricator having a valve with a connection 2 for an air-line and a valve member formed integrally with or coupled to a plunger in a chamber, a closing movement of the valve member 7 produces a suction stroke of the plunger 20 and an opening movement of the valve member 7 produces a compression stroke of the plunger to inject the contents of the chamber into a region of the valve which communicates with an air outlet 3 of the valve when the valve member is in an open position. A spring 4 urges the valve member 7 into a closed position. A lubricant chamber 8 is provided with automatic inlet and outlet check valves 9, 10. The member 7 is supported by a sleeve 12, Fig. 1, which can be adjusted to vary its stroke. An axial passage in the member 7 connects the valve 10 with an outlet passage 28 which is downstream of the valve-seat 19, or alternatively, with an outlet passage 29 which is upstream of the valve-seat 19. The valve 7, Fig. 1, may be opened automatically by the air pressure applied to the valve inlet or it may be operated by a linkage connected to the stem 16. In another embodiment, as shown in Fig. 2, the valve has a mushroom head 41 for manual operation.

Filed: 1972-07-26
Abstract: 1395925 Spreading filamentary tow INSTITUT TEXTILE DE FRANCE 26 July 1972 [30 July 1971] 34924/72 Heading D1F In the conversion of a tow of continuous filaments into a spread band thereof, a running tow is stretched by two pairs of draft rollers between which is interposed a rotary vibrator. Curved surfaces of sectional members of the vibrator engage the filaments successively to impart additional tensions thereto in the form of vibrations the majority of which have an inclined transverse resultant with respect to the plane passing through the nips of the rollers. As shown in Figs. 1 and 2, tow 1 passes from a drum 2, through tensioning bars 3 and 4 and back rollers 5, over a positively driven vibrator 6 and through front rollers 7 near the exit of which the spread band 1a subjected to the further spreading action of divergent jets of gaseous fluid emerging through an aperture 8 of a pneumatic device 9 and is carried by the gaseous sheet or curtain flowing over and along a guide plate 10 at the downstream end of which the band is taken-up by a conveyor belt (not shown). The vibrator 6 may comprise one or more curvilinear faced members constituted by plane or straight blades 21 or rigid steel wires on a support 23, Figs. 3-6 (not shown). Two superposed tows, perhaps of chemically different filaments, may be simultaneously spread. Additional rotary vibrators may be used in successive zones downstream of rollers 7, positioned above or below the level of the vibrator 6 shown. The vibrator members may be similar or different as regards material or shape e.g. the curved edges may undulate and the undulations of successively operating members may be in line or staggered, Figs. 9-11 (not shown). Blade members may comprise flaps or deflectors which create swirling air currents acting on the filaments and/or pressure fluid may be supplied from a hollow axial bore of the vibrator to emerge at the outlets of radial channels.

Title: Improvements in luminescent screens
IPC: G21K4/00
Filed: 1954-12-06
Abstract: 777,745. Luminescent screens. VINGERHOETS, A. W. Dec. 6, 1'954 [Dec. 4, 1953], No. 35270/54. Class 39(1). A screen for converting X-rays into light rays comprises a carrier plate with a large number of evenly distributed recesses each covered on its inner surface with a light reflecting layer and containing crystalline luminescent material, the luminescent light emitted in lateral and rearward directions being reflected to emanate from the front surface of the screen. Fig. 1 shows rectilinear parallel equally-spaced grooves of triangular cross-section formed in a plate 1 and covered with a layer 2 of light reflecting material and containing the luminescent material 3. The cross-section may be parabolic. In modifications, Figs. 4 and 6, (not shown) the screen is formed with a series of pyramidal or paraboloidal recesses similarly lined with reflecting material and filled with luminescent material, though the latter may only partially fill the recess. The reflecting layer 2 is X-ray absorbent particularly for the secondary X- rays, and should be of a relatively high atomic number. If its atomic number is only slightly higher than that of elements in the luminescent material, the metal of the reflective layer need only be a few microns thick. In Fig. 8 (not shown), the axes of the recesses may be inclined to focus the light rays. Curved zig-zag or oscillating grooves and recesses of spherical or conical shape are given as alternatives. The metal layer is formed by electrodeposition or by evaporation in vacuo.

Title: Improvements in or relating to the separation of lithium compounds from other compounds
IPC: C01D15/00
Filed: 1956-11-23
Abstract: A relatively insoluble salt of lithium such as the borate, carbonate, fluoride or phosphate is precipitated from a solution containing one or more other metallic compounds in the presence of an organic substance forming soluble complex compounds with said other metal or metals, at a pH greater than 7.  Suitable complexing agents are the alkali metal salts of ethylenediaminetetra-acetic acid and nitrilotriacetic acid, polymethylenediaminetetra-acetic acids and derivatives thereof, diaminocyclohexane-N : N1-tetraacetic acid and iminodiacetic acids (e.g. carboxyliminodiacetic acid, methyliminodiacetic acid, aminomalonicdiacetic acid, uramildiacetic acid, aniline diacetic acid and sulphonated and carboxylic derivatives of the latter compound, and N-g  : g -dimethylbutyliminodiacetic acid).  The complexing agent is preferably used in amounts of 120-300% of theoretical.  In the example the precipitation mixture is heated to the boiling-point. After precipitation and removal of the precipitate, the mother liquor may be concentrated and recycled; a fraction of the recycle solution may be periodically withdrawn and the complexing agent recovered for reuse.  In the case of the alkali metal salts of acids such as ethylenediaminetetra-acetic acid and nitrilotriacetic acid, the complexing agent may be precipitated and recovered from the mother liquor by addition of a strong acid.ALSO:A relatively insoluble salt of lithium such as an oxalate or stearate is precipitated from a solution containing one or more other metallic compounds in the presence of an organic substance forming soluble complex compounds with said other metal or metals, at a pH greater than 7.  Suitable complexing agents are the alkali metal salts of ethylenediaminetetraacetic acid and nitrilotriacetic acid, polymethylenediaminetetra-acetic acids and derivatives thereof, diaminocyclohexane-N : N1-tetraacetic acid and iminodiacetic acids (e.g. carboxyliminodiacetic acid, methyliminodiacetic acid, aminomalonic - diacetic acid, uramildiacetic acid, aniline-diacetic acid and sulphonated derivatives of the latter compound, and N-g  : g -dimethylbutylimino-diacetic acid).

Patent GB-361146-A (GB)
Abstract: 361,146. Calculating-machines. MONROE CALCULATING MACHINE CO., 555, Mitchell Street, Orange, New Jersey, U.S.A. Dec. 8, 1930, No. 36947. Convention date, Dec. 23, 1929. [Class 106 (i).] The totalizer carriage may be shifted in either direction under the control of manual setting means capable of being over-ridden by automatic control, and when the automatic control terminates the parts return to a setting determined by the position .of the setting means. As applied to the machine described in Specification 216,174, [Class 106 (i), Calculating &c.], a lever 321, Fig. 3, pivoted at 322 to the underside of the keyboard may be set into any one of three positions, defined by the click 323, by means of a rotary knob 324. Pivotally mounted on a member 341 is a pawl 318 adapted to be swung to right or left by one or other of two pins 320, 330 depending from the lever 321. The pawl controls the position of clutch hubs 61 provided with operating cams 59, 60 and slidable into engagement with front or rear clutch parts 62, 63 fast on the carriage-shifting shaft 46. The elements are normally in the position shown in Fig. 3, but if the knob 324 is turned clockwise the lever 321 is swung counterclockwise and the pawl consequently is caused to press one clutch hub into engagement with the part 62. When therefore the machine operates and the stop arm 24, Fig. 2, through the pusher 47 and bell crank 52 forces the shifting roller 58, Fig. 6, upwards, cam 59 is operated to effect a shift of the carriage to the right. If the knob 324 is turned counterclockwise the pawl permits the clutch hubs to slide to the rear so that a shift to the left shall occur. In order that in automatic division shifting to the right shall ensue irrespective of the setting of knob 324, the member 341 is slidably mounted so that when the lever 218 is set for division it slides the member and pawl 318 to the rear to allow the rear clutch part 63 to be engaged.

Title: Process for the manufacture of phosphatic manures
IPC: C05B17/00
Filed: 1920-12-30
Abstract: Phosphates are rendered colloidal by a process of "intensive high-speed mechanical disintegration," as defined in the prior Specification 155,836.  The phosphate is disintegrated in a high-speed mill with a large quantity of water to which has preferably been added a small amount of acid or alkali; sulphuric, nitric, phosphoric and other mineral acids are suitable.  The finely-divided phosphate becomes hydrated and colloidal and after drying is equal in value to water-soluble phosphates.  The process is facilitated by conducting it under pressure or by heating to about 90-95 DEG  C., or by adding protective colloids such as tannin, salts of lysalbinic acid, or the alkali salts of humic acid.  Bone-meal and guano may be subjected to the same process. In an example slag phosphate is first ground in a phosphate mill and is then disintegrated under the conditions described in the prior Specification, in the presence of six times its amount of water.  The resulting suspension is coagulated by means of a gaseous or liquid acid and allowed to separate into two layers. The bottom layer of phosphate mud is withdrawn, filtered and dried, preferably by blowing with hot air or by heating with waste gases.ALSO:Calciumphosphate is rendered assimilable, as a manure, by a process of "intensive high-speed mechanical disintegration" as defined in the prior Specification 155,836, [Class 1 (i), Chemical processes &c.].
