Title: Process for making an extensible dry-creped sheet material
IPC: B31F1/12
Filed: 1964-06-10
Abstract: Fibrous sheet material, such as paper is compressively creped in a substantially dry condition, i.e. up to 15% moisture content, by passing a web of the material through the nip of a pair of rolls, one roll having a hard surface and the other, an elastic roll, having a surface hardness of from 10 degrees to 45 degrees (Shore durometer) the hard roll being driven at a surface speed greater than the speed of said elastic roll.  The surface of the hard roll may be provided with an embossing pattern, e.g. to provide extensibility in the cross direction of the web.  Two or more plies of paper may be passed through the nip together to produce a laminated, creped and, if desired, embossed product in which the plies adhere to each other by interlocked fibres and crinkles.  In operation the surface of the soft roll stretches as it approaches the centre of the nip, then contracts and moves against the direction of travel of the web thus creping the sheet material.  The surface of the material in contact with the hard roll is rendered smoother than the surface in contact with the elastic roll.  The hard roll surface may be of mild steel, granite or other stone material.

Title: High speed weighing scale
IPC: G01G23/42
Filed: 1975-06-05
Abstract: 1513773 Weighing mail PITNEY-BOWES Inc 5 June 1975 [5 June 1974] 24241/75 Headings G1A and G1W A scale for weighing a piece of mail comprises a weighing tray 33 for supporting a piece of mail on edge, the tray having a base section 35 and a wall member 34 extending therefrom, means for supporting the tray for movement through a weighing range, and means for measuring the movement of the tray. The tray is supported by a pair of leaf springs 44, 45. The movement of the tray is measured by a photo-electric system comprising a light source 53, a shutter 51 mounted on the tray, a window 52, a prism 56 and an array of photodiodes 57, the photodiodes in the array being successively darkened as the tray descends. The photodiode array may be pivotally adjusted about its bottom end to vary the vertical spacing of the photodiodes so that the sensitivity of the photo-electric system matches the particular leaf springs used (Fig. 3). A spiral spring 65 connected to the tray has its tension automatically adjusted by a motor 63 and a screw and nut arrangement 64, acting under the control of the first photodiode, to zeroise the scale. On the input side of the scale are a pair of input drive rollers 32, and on the output side of the scale are a pair of output drive rollers 58, and a set of arrestment fingers 37. The rollers 58 are mounted on levers 74 for movement between inner and outer positions by means of an eccentric cam 20 acting on a wheel 202 carried by a pivoted arm 204 which engages a pullpush rod 208 linked to cranks 223. The arrestment fingers 37 are rotatable from the closed position shown to an open position under the action of a solenoid 241 which moves member 242 to the left, member 241 having slots engaging drive pins 251 of the shafts 43 of the fingers 37. In use, a letter propelled forwards by input rollers 32 is arrested and held by fingers 37, thus breaking the light transmission path from source 61 to detector 59. This breaking of the path causes solenoid 241 to be actuated to release the letter to fall on to the tray 33, and causes the commencement of the rotation of cam 200 to move rollers 58 towards their inner position, the letter being ejected when engaged by rollers 58. When the light path to detector 59 is restored, the fingers are moved to their closed position and rollers 58 towards their outer positions and another letter is propelled forwards by rollers 32. A further photo-electric detector (81, 82), Figs. 4-7, (not shown), is provided to detect the presence of a letter at the input rollers 32.

Filed: 1922-09-07
Abstract: 207,886. Bedell, E. M. Sept. 7, 1922. Magnetic, electrostatic, and like separators.- Clover seed is freed from dodder by adding to the mixed seed a powdered magnetic or electrically conductive material which will adhere to one kind of seed only, and then treating the material in a magnetic or electric separator. Magnetic iron oxide, or aluminium may be employed. The separation may be performed by passing the seed on an endless band over a magnetic pulley or beneath a magnet, or beneath an electrically-charged laterally-moving member, such as a disc of vulcanite or a belt of silk. The electric charge is maintained by friction, and the coating of conductive material modifies the rebound of the seeds attracted to the charged surface. Calcium hydrate or barium sulphate may be added to the magnetic oxide.

Title: Process for the preparation of non-corrosive hydrocarbon oils wholly or partly free from mercaptans and other sulphur compounds
IPC: C10G29/12
Filed: 1956-08-08
Abstract: Non-corrosive hydrocarbon oils wholly or partly free from mercaptans and other sulphur compounds are prepared by treating the oils with a hypochlorite solution having a pH of less than 9 and then with alkali metal mercaptides.  A pH of 8.2 to 8.5 is specified.  The hypochlorite solution may contain 0.005 to 1 mol./litre hypochlorite, e.g. sodium hypochlorite.  The mercaptides may be added in aqueous or alkali metal hydroxide solution; the oil may alternatively be treated with an alkali metal hydroxide solution, e.g. a 10-30 per cent aqueous solution of sodium or potassium hydroxide, and a hydrocarbon oil containing mercaptans, for example oil of the same origin as the oil treated with hypochlorite.  The oil and mercaptides may be stirred with a propeller mixer or turbo-mixer.  The oil may be washed with alkali metal hydroxide solution, to remove H2S, before the hypochlorite treatment, and also afterwards, when a solutizer, e.g. phenol, phenolates, alkyl phenols, alkyl phenolates, water-soluble alcohols, e.g. ethanol, and salts of fatty acids, e.g. isobutyric acid, may be added.  Any corrosive components formed during the hypochlorite treatment may be counteracted by adding a small proportion, e.g. 0.001-0.1 per cent, of a substituted or unsubstituted aliphatic or cyclo-aliphatic monocarboxylic acid having 12 or more carbon atoms, e.g. oleic acid.  Straight-run, cracked or reformed hydrocarbon oils may be treated; gasoline is specified. Specifications 761,724 and 802,675 are referred to.

IPC: G21C7/12
Filed: 1959-07-16
Abstract: 963,215. Reactor control rods. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 15, 1960 [July 16, 1959], No. 24541/59. Heading G6C. [Also in Division E2] An automatic latching mechanism comprises a member, such as a control rod 2 for a nuclear reactor, which is movable vertically in a passage 1, a detent 20, Fig. 3, supported in the passage and engageable with a recess 5 in the rod 2, a spring 22 for biasing the detent towards the rod 2, and a striker 6 operatively connected to the detent and operable by axial movement of the rod 2, to selectively cause the detent to be extended towards the rod or to be locked in a retracted position to allow freedom of movement of the rod vertically. The striker 6 is depressed by either a shoulder 4 or lip 3 on the rod, successive depressions of the striker causing the detent 20 to be held in turn in a locked position in which the detent is held in the wall of the passage and in an unlocked position, in which the detent is urged inwardly towards the rod 2. Each depression of the striker 6 moves a spring loaded latch rod 12 axially by engagement with a cam surface 7, the latch rod being bifurcated at its end and having an integral pin 15 which is situated in a slot 16 of a fixed plate. Axial movement of the latch rod 12 from the locked position of Fig. 5a carries the pin to slide along the slot until, on reaching the V-portion of the groove, the pin is urged, by springs 24 and 25 connecting the pin to a movable pivot pin 18, along the lower limb of the slot. The downward movement of the latch rod then causes one of the bifurcations to shift the pivot pin to the lower end of its slot. In this second, unlocked position the pin 23 of the detent 20, Fig. 1, is freed from a hook 13 of the latch rod. In practice, the control rod is mounted vertically so that from an unlocked position of the detent in which the detent is biased inwardly into the recess 5 of the rod and supports the rod, the rod is raised and lowered such that the lip 3 twice depresses the striker 6 to cause locking of the detent and permit downward movement of the rod. A number of detents may be used for a single control rod.

Abstract: Lithium salts of fatty acids are obtained by leaching a specially formed slurry of lithium carbonate and anisometric zeolite (see Division C1) with aqueous carbonic acid, ammonium carbonate or bicarbonate, as described in the parent Specification and Specification 935,217, and treating the lithium bearing solution thus obtained with the sodium and ammonium salts of fatty acids.ALSO:Lithium carbonate, other lithium salts and anisometric sodium or ammonium zeolites are obtained by reacting a calcined lithium bearing silicate with sodium carbonate in an amount 2 to 8 times the weight of Li2O in the silicate in the presence of sufficient water to ensure a good contact, at a temperature of 85-125 DEG  C. for 12 hours to 4 days, and separating the lithium carbonate formed from the formed anisometric sodium zeolite.  This may be effected by dewatering the slurry and leaching the solids with aqueous carbonic acid, ammonium carbonate or bicarbonate as described in the parent Specification and Specification 935,217. The mother liquor may be recycled to treat further silicate.  The lithium-bearing solution obtained from this leaching step may alternatively be treated with NaF, NH4F, sodium phosphate, ammonium phosphate and Na2SiO3 and NaAlO2 to precipitate other lithium salts. Suitable silicate starting materials are petalite, everyptite, lepidolite and b -spodumene.
