Patent GB-934385-A (GB)
Title: Substances useful as lubricant additives, processes for their preparation, and lubricants containing such substances
IPC: C08F8/00
Filed: 1961-07-25
Abstract: Lubricating oil compositions comprise additives which are polymers having a chain of at least 150 carbon atoms, which chain carries both <FORM:0934385/III/1> groups and oleophilic groups which contain at least 8 carbon atoms, or substituents containing these groups. Specified additives are those prepared by reacting hydroxylamine with copolymers of stearyl methacrylate and acrolein, and stearyl methacrylate and methyl isopropynyl ketone; and with copolymers of stearyl methacrylate with the dimethyl and diethyl acetals of acrolein in which the acetal groups have been partially hydrolysed with hydrochloric acid.  The additives may be incorporated in mineral and synthetic lubricating oils and lubricating oils containing fatty oils.  In the examples they are added to a Venezuelan paraffinic lubricating oil.ALSO:Polymers having a chain of at least 150 carbon atoms, which chain carries both >C=N-OH groups and oleophilic groups which contain at least 8 carbon atoms, or substituents containing these groups, may be prepared by reacting with hydroxylamine a copolymer of a compound containing a polymerizable double bond as well as at least one carbonyl group and a compound containing a polymerizable double bond and an oleophilic group having at least 8 carbon atoms.  Alternatively the carbonyl groups may be obtained indirectly, e.g. by reducing to aldehyde groups ester groups of an ester polymer or copolymer, oxidizing to ketone groups secondary alcohol groups or by treating acetal groups with a mineral acid. Specified carbonyl compounds are acrolein, methacrolein, beta-formyl acrylic esters, muleic dialdehyde, fumaric dialdehyde and methyl isopropenyl ketone.  Specified monomers containing oleophilic groups are alpha olefins having at least 10 carbon atoms, unsaturated esters, e.g. C12-18 alkyl methacrylates and C12-18 alkyl vinyl ethers.  Polymerization may be effected in solvents, e.g. benzene and ethanol, in the presence of catalysts, e.g. dibenzoyl peroxide and azo-bis-isobutyronitrile, and telogens, e.g. nitrobenzene. Uniform copolymers of monomers having very different reactivities may be prepared by adding one of the monomers incrementally. Examples describe the reaction with hydroxylamine of copolymers prepared by (I, III, IV and V) copolymerizing stearyl methacrylate and acrolein in benzene in the presence of benzoyl peroxide, (II) copolymerizing stearyl methacrylate and acrolein in benzene in the presence of benzoyl peroxide and methanol and partially hydrolysing the dimethyl acetal groups in the presence of hydrochloric acid, (VI) copolymerizing stearyl methacrylate and acrolein diethyl acetal in the presence of azobis-isobutyronitrile and partially hydrolysing the acetal groups with hydrochloric acid and (VII) copolymerizing stearyl methacrylate and methyl isopropenyl ketone in benzene in the presence of benzoyl peroxide.  The products are useful as lubricating oil additives.

Title: A system of automatically controlling road vehicles
IPC: G05D1/02
Filed: 1959-08-10
Abstract: 886,166. Automatic position and speed control systems. GENERAL MOTORS CORPORATION. Aug. 10, 1959 [Aug. 25, 1958], No. 27203/59. Class 38 (4). [Also in Group XL (c)] In an automatic control system for a road vehicle a pair of electric conductors are spaced in a regularly recurrent pattern along a desired course and a control apparatus in the vehicle detects the magnetic field due to an alternating current in the conductors. As shown, Fig. 3, a pair of conductors 22, 24 buried in a roadway are energized from an alternating-current generator 28. The magnetic field along the centre-line of the conductors is at a minimum where the conductors cross and the field in each loop 30 is reversed relative to the field in adjacent loops. Pick-up coils 34, 36 are mounted on the vehicle and the voltages induced are applied to capacitors 42, 44 through rectifiers 38, 40. The voltages across the capacitors are in opposition and are equal when the coils are symmetrically situated above the conductors. When the road vehicle is off-course, the voltage across the capacitors represents in magnitude and sign the deviation, and controls a steering servo 46 so as to correct the deviation. The recurrent pattern of the conductors causes the voltages induced in the coils 34, 35 to be modulated at a frequency dependent on the speed of the road vehicle, and by a demodulator 48, responsive to the modulation frequency, a speed-dependent voltage is derived and compared with a reference voltage from a demodulator 50 responsive to the frequency of the generator 28. The difference between the speed and reference voltages actuates a throttle servo 52 so as to maintain the vehicle speed constant. In another embodiment, Fig. 8, the conductors 66, 70 are disposed as shown and pick-up coils 76, 78 are positioned one loop length apart along the length of the vehicle and the voltage used in either coil is used to control the vehicle speed. The sum of the induced voltages in coils 76, 78 is substantially constant and can be used to transfer information, such as a voice signal or a command speed signal, to the vehicle. The command signal may be derived from a third cable laid in the road.

Abstract: 921,437. Seals and sealing. W. R. GRACE & CO. Aug. 5, 1960 [Aug. 18, 1959], No. 27316/60. Class 146 (2). An adjustable sealing device for putting a seal 52 around the twisted necks 54 of flexible bags comprises a pair of jaws 14, a plunger 24 having opposed cams 22, a floating punch 28 slidable on the plunger 24 and spring-urged to clip the seal, and means to vary the pivotal motion of the sealing jaws so that various sizes of seals, Fig. 4, may be slid into position. The seals are supplied from stepped guideway 70 which allows the different size seals to rest and according to the one chosen, the device is adjusted by the position of the plunger 24. This is determined by a four-position cam 40 the sides 42, 44, 46, 48 being different distances from the axis 50. The first action of sealing pressure folds the upper arms 64 together and when the jaw follower rollers 20 reach the flat part 23 of the plunger 24 no further pivoting of the jaws 14 occurs but the plunger continues to squash the seal into the shape shown in Fig. 8. The punch 28 may form marks on the seal. The seals are claimed in Divided Specification 921,438.

Abstract: 304,624. Pugh, J. V. Oct. 20, 1927. Detaching from, and attaching to, permanent hubs; suspension-spoke wheels; spokes, securing and adjusting. - A detachable wheel is formed with two or more sets of spokes with at least one set comprising two or more groups extending to the rim from different centres around the wheel-axis, tension being set up in the spokes by relative axial displacement of the sets. In all the constructions shown, the outer set of spokes is connected to a central collar or the like adapted to engage an axially-adjustable end-cap on the axle-hub, the inner groups being connected to similar devices on a flange (or the brake-drum) of the axle-hub. In the form shown in Figs. 1 and 2, the outer spokes e are carried by a flanged collar f adapted to fit on to a nipple a<3> which projects from a cap a<2> threaded on the axle-hub a. A spacer-ring g is shown fitted between the limbs of the hairpin spokes. The inner spokes e', e<2> are carried by similar collars f<3> adapted to be fitted over threaded studs c projecting from the hub-flange a<1>. After assembling and securing the inner spokes, the cap a<2> is screwed outwards on the hub a to set up the desired tension in all the spokes. In modifications, the outer spokes may be welded or otherwise permanently secured to a plain collar (or closed cap) adapted to fit on to the cap a<2>, or directly against the end of the axle. Fig. 11 shows an example of the latter arrangement in which separate spokes are connected to a collar n fitting over the nose m<4> of the axle m. The collars n<1> carrying the inner groups of spokes are bolted to a composite flange m<3> which is secured by means of a split ring fitting a groove m<2> in the axle. 'When, as shown in Fig. 11, two sets of spokes extend from the rim to the inner side of the wheel centre, these may be carried by pairs of collars with slightly-displaced apertures for the flange-bolts. By this arrangement, the sets of inner spokes are tensioned as the collars are forced home on the bolts. Fig. 9 shows a modification in which the inner groups of spokes are attached to eyelets l having keyhole slots l<1> for engaging headed hooks or the like fixed to the axle-hub flange on the brake-drum. Fig. 18 shows a further modification in which the inner sets of spokes are attached to sleeves t adapted to fit over long bolts v as used in the attachment of other types of wheels.
