Title: Process for the manufacture of nitrogen-containing derivatives of hexoses and of compositions and baths containing the same
IPC: C07H13/12
Filed: 1948-08-31
Abstract: Nitrogen-containing derivatives of hexoses are prepared by reacting hexoses (or polysaccharides which become hexoses under the reaction conditions), in the presence of a dehydrating agent with organic compounds of the general formula <FORM:0653775/IV (b)/1> in which R represents hydrogen or an alkyl, aryl or alkaryl group and X represents an oxygen or sulphur atom or the =NH group, or with melamines.  Sulphuric acid, zinc chloride and phosphoric acid are suitable condensing agents.  The reactants are conveniently stirred together in molten condition, preferably in the presence of not more than 20 per cent of water.  In examples: (1) glucose hydrate is reacted with urea to produce a glucose ureide; (2) cane sugar is reacted with urea in the presence of some water; (3) the urea of (2) is replaced by thiourea; (4) glucose hydrate is reacted with guanidine, and (5) glucose hydrate is reacted with melamine.ALSO:Cellulosic textile materials are crease-proofed and shrink-proofed by treating them in the presence of an aldehyde with a nitrogen-containing derivative of a hexose prepared by reacting a hexose (or polysaccharide which becomes a hexose under the reaction conditions), in the presence of a dehydrating agent with a compound of the general formula <FORM:0653775/IV (c)/1> in which R is hydrogen or an alkyl, aryl or alkaryl group and X is an oxygen or sulphur atom or the =NH group.  Examples are given of the reaction of glucose hydrate with urea, thiourea, guanidine or melamine, and of cane sugar with urea.

Title: Improvements in or relating to hydraulic buffer systems
IPC: B64F1/06
Filed: 1945-09-06
Abstract: 655,030. Railway buffers. THOMLINSON, J., and BODDINGTON, L. Sept. 6, 1945, No. 22984. [Class 104 (ii)] [Also in Groups XXXII and XXXIII] A hydraulic buffer system, which uses the retarding force derived from the displacement of hydraulic fluid by means of a ram 7 working in a cylinder 1, is arranged with one of these elements mounted on the object to be arrested and the other element stationary, the ram being normally completely outside, and unconnected to, the cylinder, but adapted, in the process of arresting the moving object, to enter the cylinder after piercing a diaphragm 5 closing the entry end of the latter. The buffer shown in Fig. 4 is intended for the purpose of arresting at the end of its run the rail trolley upon which an aircraft is carried during launching from a catapult, and comprises the cylinder 1 which is closed at one end by a screwed plug 2, and is fitted at the other end with an annular choke 3 of less diameter than the bore of the cylinder. The part 4 of the choke 3 also serves as a retaining nut for the diaphragm 5, which is of thin metal or composition. The ram 7, which has an integral portion 7b for bolting to the supporting structure, comprises a part-spherical nose and a tapered portion gradually increasing in diameter from the nose to the root portion 7a. The profile of the tapered portion of the ram is so ground that, on progressive entry of the ram into the cylinder, the dimension of the annular space within the ring 3 will decrease continuously and the retardation produced by the discharge of fluid through this annular space will be substantially uniform. Towards the end of the stroke the root 7a of the ram will engage the close fitting choke ring 3, so that, theoretically, the ram should then be brought to rest; in practice, however, the nose of the ram might be driven home against the end of the cylinder, and, in order to prevent this, the co-operating end faces of the ram nose and cylinder may be of part-spherical shape, or a yielding stop element, such as a hard rubber ring, rope grommet, or lead packing, may be provided on the ram nose. If desired, the object to be arrested may be retarded in two stages, the first stage being constituted by the engagement of the ram on the moving object with a cylinder 1 which is movable in the path of the ram; this cylinder may, itself, be formed as a ram for engaging the stationary cylinder 8 as shown in Fig. 6, or it may be provided with a second cylinder 10 for engaging a stationary ram 8 as shown in Fig. 7. Alternatively, the object to be arrested may be fitted with a cylinder engaging, at the first stage, a ram which is mounted in the path of the cylinder and is either itself formed with a cylinder for engaging a stationary ram or provided with a second ram for engaging a stationary cylinder.

Abstract: 1525848 System for dismantling used vehicles and storing the removed parts J M HOLLANDER 1 June 1977 23154/77 Heading B8W Used vehicles are dismantled and the reusable parts stored in a warehousing system including a conveyer, e.g. a belt conveyer 36, on which a used vehicle is transported during disassembly, means for removing used parts from the used vehicle, a storage area for storing the removed parts, means for identifying the removed parts and means for maintaining an inventory record relating to the removed parts. As shown, used vehicles enter main building 10 at entrance 12 and are raised by a travelling hoist 35 in an inspection area 17 where the vehicle is identified and an appropriate inventory form selected. After testing the vehicle engine by analysing equipment 34, to enable a decision to be made as to whether it should be removed whole or dismantled, the petrol tank is pumped dry and removed to fire-proof area 31, various parts are labelled for removal, and some parts removable only from below may be removed prior to placing the vehicle on conveyer 36, using the hoist 35 or/and a ramp 38. The vehicle then proceeds along the conveyer, together with its inventory form and passes successively a number of stations including labelling stations 24, parts testing areas 21 and cleaning areas 22, movement of the vehicle being controlled by conveyer drive controls 26 operable at each of several positions along the conveyer. At each station where dismantling is effected, use is made of tools connectible to pneumatic bases or electric lines, which are available at points such as 6, 7, 8 and 9, and of acetylene cutting torches 30, or arc welding or power saw equipment. The removed parts are placed in storage racks 48 which are loaded and unloaded by pallet trucks or manually, gangways 46 being provided for this purpose. Information on all the parts removed is supplied to an inventory record store device 52 in an adjoining sales building 32 including a sales counter 33. The store device 52 can be of any known type and have associated computerscanning equipment. After removal of all usable parts not requiring a hoist, a hoist 28 is used, e.g. for removal of rear axle, axle shaft, transmission and larger drive shafts. At the end of the conveyer a further hoist 49 lifts the remaining hulk of the vehicle and delivers it to a crusher 50 or to a transport vehicle for delivery to a crusher. 23, 25, 27 denote various test equipment, cleaning equipment and labelling equipment, used at the stations 21, 22 and 24, respectively.

Title: Production of cyclohexane
Inventor: BENNETT RUFUS BURNELL
IPC: C07C7/00
Filed: 1956-07-27
Abstract: Cyclohexane is recovered from a fraction containing at least 70 per cent and not more than 88 per cent by volume of cyclohexane in admixture with non-naphthenic hydrocarbons, by chilling the fraction to a temperature between - 10 DEG  and - 100 DEG  F. to form a slurry of cyclohexane crystals in a mother liquor, and <PICT:0800983/IV (b)/1> separating the crystals from the slurry.  An hydrocarbon fraction consisting of cyclohexane in admixture with non-naphthenic hydrocarbons including dimethyl pentanes, is fed by a line 11 to a fractionating column 12, where a first fraction comprising an azeotrope of cyclohexane and dimethyl pentanes is discarded as overhead fraction by line 35, and a second fraction containing between 70 and 88 per cent by volume of cyclohexane is passed by a line 14 to a chiller 15.  The fraction in chiller 15 is cooled indirectly or by addition of a refrigerant such as carbon dioxide or propane, to form a slurry at a temperature between - 10 DEG  and - 100 DEG  F., which is passed by lines 17 and 18 to a cooled holding tank 20 where the crystals are allowed to grow, the slurry then passing by a line 25 to a cooled centrifuge 26.  If desired, the slurry may by-pass the tank 20, and pass by lines 17 and 25 to the centrifuge 26.  Cyclohexane crystals are separated in the centrifuge 26 and removed by a line 31, and mother liquor withdrawn by a line 30 is either recycled to line 11 or removed by line 32.  The centrifuge 26 may be replaced by a filter.

Abstract: 295,588. Addressograph, Ltd., (Assignees of Duncan, J. S., and Hubbard, H. E.). Dec. 3, 1927, [Convention date]. Delivery apparatus. - In a machine for printing addresses or other matter on magazines, newspapers, &c., by means of printing- plates moved successively into printing position, the magazines. after being addressed, are sorted into groups by providing a tab on the first or last printing-plate of a series and causing the tabs to operate jogging - mechanism arranged to push a magazine to one side so as to indicate to an operator the beginning or the end of a group. As shown, address-plates 10, Fig. 1, stacked in a hopper 9, are moved along a transverse guideway into printing position. Each plate 10 on its way to the printing position depresses a tripfinger 11, Fig. 3 : a tabbed plate, however, holds the finger down longer than an untabbed plate, and thereby operates the jogging- mechanism. The jogger consists of a reciprocating bar 39, Fig. 5. adapted to engage one of a line of magazines fed by tapes 58 in a direction at right angles to that of plates. The bar 39 is carried by adapted to be oscillated about a pivot 28 by a cam 29<1> loosely mounted on a shaft f to the shaft by a pawl 31 on the ca pawl is swung about a pivot 30 so 35<1> engages a notch 34 in a boss on The pawl 31 is normally held away f against spring action by an ann 27 pivoted at 28 and connected by a link 24 to an arm 21 fixed on a shaft 19 carrying an arm 18, Fig. 3, connected by a rod 17 to an arm 15 pivoted at 15<1> and formed at the end as a latch 14 engaging the lower end of a bar 12 carrying the pawl 11. A spring 16 constantly pulls the rod 12 to the right and presses a roller 22, Fig. 5, on the arm 21 against a cam 23 on the shaft 6. An untabbed address-plate releases the arm 15, but the bar 12 latches on to the arm 15 before the low part of the cam 23 reaches the roller 22; a tabbed plate, however, by depressing the finger 11 for a longer period allows the arm 21 to swing to the left, Fig. 5, and turns the arm 27 away from the pawl 31 which couples the cam 29<1> to the shaft 6 for one revolution while the jogger 39 is actuated. Feeding sheets.-The Specification as open to inspection under Sect. 91 (3) (a) comprises also sheet-feeding mechanism. This subject-matter, however, does not appear in the Specification as accepted, and is described in Specifications 295,403 and 295,404.
