Patent GB-660918-A (GB)
Title: Process for the production of phosphorus-containing organic compounds and the compounds so produced
IPC: C07F9/38
Filed: 1949-04-07
Abstract: Olefinic compounds are reacted with phosphorus compounds containing the group H-P--> O in the presence of free radicals. The olefinic compounds may be hydrocarbons, ethers, alcohols, sulphides, disulphides or esters containing one or more double bonds, preferably alkenes, dialkenyl ethers, alkenols and alkyl alkenoates; they may contain up to 20 carbon atoms, and many suitable compounds are specified, including mercaptans and chlorine-substituted compounds. The phosphorus compound preferably has the formula <FORM:0660918/IV (b)/1> where Z is a hydrocarbon radical free from multiple bonds or an inorganic cation, and Y is hydrogen, a hydrocarbon radical free from multiple bonds or is OZ.  Such compounds are the salts and esters of phosphorous and hypophosphorous acids and of organic phosphinic acids.  The free radicals may be produced by thermally or photochemically dissociating a solvent or other compound added for this purpose, e.g. N-chloramides, organometallic compounds, peroxides or carbonyl compounds such as acetone; 0.5 to 10 moles. per cent of such initiator may be present.  Other solvents such as alkanols and hydrocarbons may also be added.  The reaction may take place in the liquid or vapour phase at a temperature between 0 DEG  and 200 DEG C., preferably between 50 DEG  and 150 DEG  C.; the pressure is normally atmospheric but may be lower or higher.  The process may be continuous or batch-wise.  When using equimolecular amounts of the reactants or an excess of the phosphorus compound, 1 : 1 addition normally occurs.  By using a 2-3 molar excess of the olefine, however, an addition product may be formed containing several molecules of the olefine.  In the examples the olefinic compounds used are: 1-hexene, 1-octene, 1-decene, 1-tetradecene, cyclohexene, the mixture of C8-C18 olefines from the cracking of petroleum wax, allyl alcohol, diallyl ether, diallyl sulphide, diallyl disulphide, divinyl sulphide and ethyl crotonate; where the reactant contains two olefinic linkages, one or both may react depending on the conditions, and in the case of ethyl crotonate, the product is a mixture of 2 isomers.  The products obtained are sodium and ammonium alkylphosphinates from sodium and ammonium hypophosphites, dibutyl alkylphosphonates from dibutyl phosphites, diethyl and dipropyl alkylphosphonates similarly, and the ethyl ester of a phenylalkylphosphinic acid from ethyl benzenephosphinate.  The initiators used are acetone, di-tertiary butyl peroxide, di-tertiary butyl permalonate and 2 : 2-di-(tertiary butyl-peroxy)-butane.  In one example, sodium hexane-1-phosphinate is prepared from 1-hexene and sodium hypophosphite, and a further quantity of 1-hexene and initiator added to the reaction mixture to give sodium di-hexane-1-phosphinate.  The hydrolysis of dibutyl cyclohexanephosphonate with hydrogen chloride to give cyclohexanephosphonic acid is also described.

Title: Improvements in leather working machines
IPC: C14B1/10
Filed: 1919-04-15
Abstract: 148,606. Percival, S., (Careleton Ruhe Co.). April 15, 1919. Rotating-tool machines; work-supporting surfaces.-A leather-working machine has changeable feed-rolls, working rolls and bed so as to be suitable for various processes. Fig. 4 shows an arrangement for unhairing hides, by which both operations of coarse and fine hairing will be performed. Feed-rolls 21, 22 draw the hide upwards against the action of bladed work rolls 4, 5 each rotating preferably in the same direction, the hide resting on a bed roll 15. The pitch of the helical blades of the roll 4, measured along the axis, is preferably 42 inches, while that of the roller 5 is about 74 inches. The roll 4 rotates more quickly than the roll 5, thus acting as a tension member. The feed-roll 22 and the bed roll 15 are both mounted on two arms hanging from a shaft located above the machine, by which they can be simultaneously moved away from or towards the feed-roll 21 and work rolls 4, 5. The mounting is such that when the rolls 22, 15 are in their separated position for removing or introducing the hide, said hide will hang freely from the feed-roll 22 without touching the bed roll 15. The arms supporting the rolls 22, 15 are poweroperated, and the weight of the hanging mass assists the movement of the bed roll 15 into engagement with the work rolls 4, 5. The feedrolls 21, 22 are provided with pointed meshing teeth, so that when they are brought together, the power-driven roll 21 communicates its motion to the roll 22. The rolls 21, 22 are furnished with longitudinal corrugations 44, and the roll 22 has in addition circumferential grooves which retard lateral movement of the hide. The rolls 15 and 21 are mounted to rotate in swivel bearings and are spring-pressed and finely adjustable to and from the work rolls 4, 5 and the feed-roll 22 respectively. For fleshing hides the arrangement shown in Fig. 5 is employed, in which the rolls 21 and 22 are interchanged to correspond with the reversal of the hide. The work roll 74 is fitted with helical blades of 10 in. pitch and rotates faster than the lower work roll. For putting out and staking hides, the feed-rolls 21, 22 are replaced by felt rolls 76, 77, Fig. 7, the work rolls being the same as those for unhairing. The bed roll is replaced by a bolster 82 preferably consisting of a bed forming two-thirds of a circle and covered with resilient material 84, preferably felt, and a strip of leather 85. Attached to the bed is a slicker blade 87 having a rounded nose over which the hide passes in travelling between the work rolls.

Title: Improvements in a fiber optical image transfer device
IPC: G02B23/26
Filed: 1961-03-16
Abstract: 923,747. Fibre optical devices. A. ABBEY. (American Optical Co.). March 16, 1961, No. 9718/61. Class 81 (2). [Also in Groups XX and XL (a)]  A fibre optical image transfer device such as an endoscope or a gastroscope comprises bunched light transmitting fibres, each having a high index core and a low index coating forming a highly reflecting interface to light rays incident thereon at angles greater than the critical angle of reflection at said interface, the coating having such absorbing characteristics that light entering the core of the fibre and incident on the interface at angles less than the critical angle of reflection at the interface will be substantially absorbed. One of the fibres is shown in Fig. 1 as comprising a core 11 as of high index glass and coating 10 of a low index glass which includes for example equal quantities of chromic oxide and gold chloride so as to absorb light rays incident on the core-coating interface at angles less than the critical angle of reflection. Preferably, the coating is such that in a thickness equal to the ratio of volume of coating material to core material multiplied by the length of the fibre, the coating will only transmit substantially 10% of all light which passes thereinto. Each fibre may be formed by placing a rod of core glass of a given initial cross-sectional size within a surrounding tube of coating material of an initial thickness which is in accordance with the crosssectional size of the core and then heating and drawing the assembly down to a desired fibre size and length.

Filed: 1957-03-25
Abstract: 879,533. Automatic attitude control systems. ENGLISH ELECTRIC CO. Ltd. March 19, 1958 [March 25, 1957], No. 9785/57. Class 38 (4). [Also in Group XXIV] A three-axis pick-off is associated with a body which is maintained in the same attitude about three axes passing through a point as another body mounted for movement about a spherical bearing, the centre of which is displaced from said point. In Fig. 1, as in Specification 873,128, a carrier 10 is mounted for limited universal movement on a shaft 12 by means of a spherical bearing 11, and the attitude of the carrier is automatically adjusted electromagnetically under control of gyroscopes such as gyro 13 mounted on the carrier. The carrier is, however coupled through four universally-pivoted rods 16 to a follower ring 14 which can rotate within a gimbal ring 15c mounted in a further gimbal ring 15b pivoted relative to the casing of a missile in which the whole apparatus is located. A coupling 18 between an opposite pair of rods 16 provides them with the necessary torsional rigidity. The attitude of follower ring 14 is thus always the same as that of the carrier and pick-off devices for detecting movements about each of three perpendicular axes are associated with the follower ring 1 instead of the carrier. The pick-off devices may be potentiometers or variable inductive devices or as in Fig. 2 (not shown). Bowden cables formed by stainless steel wire in nylon tubing suitably attached where necessary to the gimbal rings may transmit movements of follower 14 to indicators or electrical transmitters located remotely.

Abstract: 794,114. Building yarn packages on spinning &c. machines; bobbins. PRINCESMITH & STELLS, Ltd. March 20, 1956 [April 5, 1955], No. 9917/55. Classes 120(2) and 120(3) Long yarn packages are produced without affecting the axial length of the balloon by winding the yarn on a package support comprising nested coaxial inner and outer rigid members movable axially relative to one another to permit extension of the support so that the package is built on both members. A hollow spindle 8 is rotatably carried by a rail 10 which is moved downwards by a chain 11 as the yarn package is built. Passing through the spindle 8 is a plunger 21 supported in a rail 23 and rotated by a tape 24 and whorl 25 keyed to the plunger 21. There is a splined connection between the plunger 21 and spindle 8 for rotating the latter. Guide collars 29 on the plunger 21 are a sliding fit inside the inner of two nested package tubes 36, 37 which abut against shoulders on the spindle 8 and lower collar 29. Bayonet or other detachable connections may be provided between the outer tube 36 and the spindle 8. As the outer tube 36 descends during package building, the plunger 21 and inner tube 37 do not descend until the outer tube 36 has almost been covered with yarn and the tubes 36, 37 have reached their full extension, whereupon the plunger 21 also begins to descend by reason of an adjustable stop 34 contacting the rail 23 and pressing it down against the pressure of a spring 31. In another embodiment, the whorl 25 is keyed to the spindle and the plunger takes its drive from the spindle. According to' the Provisional Specification, the package support may consist of more than two nested tubes.
