Title: Improvements in or relating to a shock proof container wagon
IPC: B61D3/20
Filed: 1935-07-23
Abstract: 440,937. Vehicles with removable bodies. KELLETT, W.P., 16, Hilltop Road, Bronx - ville, New York, U.S.A. July 23, 1935, No. 20902. [Class 103 (iv)] In a railway or like wagon having a removable container body and in which buffing devices are arranged to absorb shocks between the container and wagon body or underframe, the shock-absorbing device comprises elements which are adapted to engage both ends of the container and are associated with springs located substantially mid-way of the length of the wagon, so as to resist movement of the container in either direction. In the arrangement shown sockets at each end of the container 6, Fig. 2, are engaged by adjustable screws 15 carried by abutments 14 which are pivotally mounted in slidable blocks 10, Fig. 5, so as either to be swung upwards through apertures 7 in the floor 4 into operative position, or to fold downwards into an inoperative position. The blocks 10 are interconnected by means of longitudinal rods 21, 28, the central rod 28 being guided in sleeves 26 mounted in fixed blocks 24 and being surrounded by springs 31, 32 operating between the blocks 24. By this arrangement, the springs are compressed in whichever direction the container tends to be displaced.

Title: Process for the preparation of cyclopropanes
IPC: C07C1/32
Filed: 1960-06-15
Abstract: Cyclopropane or a hydrocarbon substituted derivative thereof is prepared by reacting an allyl halide or hydrocarbon substituted derivative thereof with diborane to form an addition product and treating the addition product with an alkali.  Reaction of an allyl halide of the formula CH2=C(R)-CH2X, in which R is hydrogen, alkyl or aryl and X is chlorine or bromine, with diborane is believed to give compounds of the formulae (X-CH2-CH(R)-CH2)3B, (X-CH2-CH(R)-CH2)2BX and (X-CH2-CH(R)-CH2)BX2. This reaction is effected by bubbling diborane into a solution of the allyl halide in dimethyl ether, diethyl ether, diethylene glycol dimethyl ether or tetrahydrofuran at - 10 DEG  to 35 DEG  C. using a mol. ratio of allyl halide to diborane of 1-6 : 1.  A 10% aqueous solution of sodium or potassium hydroxide in a mol. ratio to halide of 1-2 : 1 is added at 20-70 DEG C. and the cyclopropane recovered by distillation or separating the organic phase and extracting with heptane, methylene chloride or diethyl ether.  The preparations of cyclopropane, and methyl-, phenyl-, benzyl- and butyl-cyclopropanes are described.

Title: Impulse-responsive stepping device actuated by magnetic torque
IPC: H01H51/08
Filed: 1948-08-10
Abstract: 658,622. Motors. LEIGH ELECTRIC CO. Aug. 10, 1948, No. 21102. Convention date, Oct. 24, 1947. [Class 35] [Also in Groups XIX, XXXVII, XXXVIII and XXXIX] An electromagnetic impulse-responsive device, e.g. a step-by-step switch, comprises an armature and coacting polepiece so formed with angularly-disposed co-operating teeth that on energization the armature moves both axially and angularly and, on de-energization, angularly only, relative to the polepiece. Figs. 1, 3, 4 show a selector switch comprising a magnet coil S, the magnetic yoke member 30 of which has polepieces 36, 37, Fig. 4, arcuately shaped to coact with a disc armature 25 carried by a shaft 42 bearing in non-magnetic plates 40, 41 secured to the yoke. The armature is normally offset axially relative to the polepieces, Fig. 3, and both polepieces and armature are provided with angularly disposed co-operating teeth, Fig. 4a (not shown), so that when the coil S is energized the armature moves in a manner analogous to that of a screw in a nut, i.e. axially downwards, Fig. 3, and angularly. The axial movement is effected against the bias of coaxial and oppositely-wound springs 43, 44 which when the coil is de-energized, function as a detent so that the armature moves axially only under the action of these springs. In this manner the armature shaft is advanced angularly at each energization a distance corresponding to the pitch of the teeth on. the armature. Figs. 11, 12, 13 show an indicator drum 88 carried by an armature shaft 79 selectively positioned as previously described. In this case a contact ring 92 and segment 91 are carried on opposite faces of an insulating disc 90 which is rotated with the shaft 79 through a bushing 86 splined to the shaft. The drive magnet 75 is pulsed to step the indicator by operating impulse contacts IMP, and is subsequently zeroized by actuating a switch 105 to energize a relay 101 which disconnects the impulse contacts IMP, and connects positive over an interrupter 102 to the stepping magnet which advances the indicator to zero when the stepping circuit is broken at the gap in the segment 91. The indicator drum 88 may be secured to the bushing 86 in which case it will rotate only and not move axially at each shaft step. In a modified construction, Fig. 15, the magnet yoke 131 has a single ring-shaped polepiece 135 surrounding the armature disc 146 which is normally axially offset downwards relative to the polepiece by oppositely arranged spiral springs 138, 139, formed by pressings from a plate 137 screwed to the polepiece. The armature shaft 145 bears in a recess in the magnet core 130 which engages in a recess in the armature. The operation is similar to that of the previous embodiments.

Title: Improvements in automatic lathes and like machines
IPC: B23Q39/04
Filed: 1936-07-30
Abstract: 464,733. Lathes. FAIRWEATHER, H. G. C. (National Acme Co.) July 30, 1936, No. 21125. [Class 83 (iii)] Chucks.-An automatic multi-spindle or single-spindle bar-stock lathe has a main tool slide and an auxiliary tool slide which is movable relatively to the main slide and carries chucking or pick-up means rotated synchronously with the work spindle, the main slide serving during its advance movement to close the pick-up means onto the work to support and rotate it during the operation first of a parting tool and then of a finishing tool. As applied to a multispindle work turret lathe, the driving shaft 4, Fig. 5, of the work spindles 3 passes through the usual main tool-slide 5 carrying the endworking tools. The slide 5 carries an auxiliary slide 6 movable longitudinally thereon and provided with a pick-tp work holder consisting of a housing 7 fitted with a rotary spindle 8 and a collet 8<1>, Fig. 4. The spindle 8 is rotated at the same speed and in the same direction as the work spindles by a shaft 9 driven from the central shaft 4. The auxiliary slide is operated by cams 12 mounted on the usual cam-shaft and connected through a link 13, arm 14, and rod 15, to the housing 7. The spindle 8 is moved forward at the cutting- off station to grip the end of a piece W which is being cut off by a tool 31, and is then partially returned, Fig. 11, with the severed piece to permit a finishing tool 35 to be brought into alignment therewith, whereupon the spindle 8 is again moved forward for the finishing operation and then finally moved back and the completed work-piece ejected. The slide 5 has a trip 17 coacting with the end 18 of a swinging finger 19 operating the sliding chuck yoke 21. After the pick-up spindle has been moved up to the work-piece, the subsequent advance of the main tool slide 5 actuates the chuck yoke to grip the work. A fixed bracket 32 carries a swinging arm 33 fitted with the holder 34 of the finishing tool 35 which may perform a boring, drilling, facing, chamfering, reaming or other operation. The arm 33 is connected by an arm 37 to a lug 36 on the cross slide 30 so that as the cross slide is moved forward for the parting operation the tool 35 is retracted, and vice versa. When the finishing tool is in position, the pick-up spindle is moved to carry the work up to the tool and the pick-up then fully withdrawn. During this movement the yoke 21 engages a stop rod 24 to open the chuck, whereupon the workpiece is ejected by a spring plunger 40 located within the collet. The fully withdrawn position of the pick-up to cause ejection of the work is shown in dotted lines, Fig. 11.

'[Class 34(ii)] A tumbler type clothes-drying apparatus has a lint trap comprising a rotary screen or filter 4 in the air outlet and a concentrically arranged rolling element mounted over part of the screen and resiliently pressed towards it, the element having a roughened surface so that lint collected on the screen is compressed and rolled into rolls between the screen and element. The screen 4 is placed in a casing 3 on top of the casing 2 of a drying cylinder 1, one end of the screen being closed and the other connected to the air outlet pipe. The surface of the screen has teeth 7 and a ruler 8 with teeth 9 can be turned around a shaft 10 which is parallel to the axes of the cylinders 1 and 4, the ruler 8 being actuated by rods 11, 12. A plate 13 is fixed to the casing at one of its edges and compression springs 14 are provided between the plate and the casing 3. By means of the rods 11, 12, the ruler 8 is periodically turned around its shaft so that the teeth seize the lint on the screen 4 which lint becomes compressed and rolled between the screen and plate 13. the rolls of lint 15 falling between the casing 2 and the rotating cylinder 1 which transports them to a collecting place. The Specification as open to inspection under Sect. 91 comprises also (see Fig. 3 (Cancelled)), a drying cylinder 1 with a fixed semi-cylindrical screen 21. A plate 22 concentric with the drying cylinder is resiliently mounted on the casing 2 between it and the cylinder. When the apparatus is stopped working the lint falls from the screen on to the cylinder 1 and when the rotation of the cylinder re-starts the lint is transported between the latter and the plate 21 where it is rolled up and falls through a slot 23 into a container 24. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to preparation of amides of lysergic acid and novel mixed anhydride useful in such preparation
Filed: 1956-07-10
Abstract: The invention comprises a mixed anhydride of lysergic and sulphuric acids, the preparation thereof by reacting sulphur trioxide with lysergic acid or a cationic salt thereof in a dispersant inert to the reactants and at a temperature not substantially exceeding room temperature, and the conversion thereof (if desired without isolation) to amides of lysergic acid by reaction in a similar dispersant with nitrogenous bases having at least one hydrogen attached to nitrogen.  The term "lysergic acid" includes d- and l-lysergic and d- and l-isolysergic acids, also 5:6-dihydrolysergic acid and its acyl derivatives and 10:11-dihydroisolysergic acid, and suitable salts thereof are the lithium, potassium, barium, lead, calcium, ammonium, triethylamine and trimethylamine salts. Preferably about 2 molecular equivalents of SO3 (advantageously in the form of a complex with the dispersant employed) are used to one of lysergic acid or salt, and about 5 of the nitrogenous base to one of the mixed anhydride.  In examples: (1) cooled solutions of potassium d-lysergate monohydrate and SO3, both in dimethylformamide, are mixed, and the mixed anhydride is precipitated by adding cooled anhydrous ether; (2) solutions of lithium d-lysergate and SO3-dimethylformamide complex, both in dimethylformamide, are mixed, and the resulting solution is stirred with L-(+)-2-amino-propan-1-ol to produce ergonovine (isolated as its maleate) and some ergonovinine (as nitrate); (3) the lithium d-lysergate in (2) is replaced by the barium salt and the L-(+)-base by its racemic form; (4) the solution of lithium d-lysergate in (2) is replaced by d-lysergic acid and the base by its N-benzyl derivative, yielding N-benzylergonovine acid maleate; (5) the product of (1) is reacted (without isolation) with aqueous ammonia to form ergine (as acid maleate), or with hydrazine hydrate; (6) and (7) aniline and methylaniline similarly give d-lysergic acid anilide (as acid maleate) and methylanilide (as dibenzoyl-d-tartrate); (8) potassium d-lysergate is reacted as in (2) and the product reacted with l-ephedrine; (9) cooled solutions of potassium d-lysergate in hexane and of SO3 in acetonitrile are mixed and the products reacted with a solution of diethylamine in ether, the isomeric diethylamides produced being separated by chromatography; (10) by a process similar to that of (1), racemic potassium lysergate and L-(+)-2-aminopropan-1-ol yield racemic ergonovine (as maleate); (11) potassium d-dihydrolysergate is reacted as in (9).  Additional amines specified are ethylamine, glycine, propylamine, diphenylamine and isovalinol.
