Title: Method for controlling viscosity of organic liquids and compositions containing said organic liquids
IPC: C10M143/00
Filed: 1975-04-24
Abstract: 1499733 Lubricants EXXON RESEARCH & ENG CO 24 April 1975 [17 May 1974] 17029/75 Heading C5F A composition comprises a major amount of an organic liquid and minor amounts of an ionic polymer and of a cosolvent. The organic liquid has a solubility parameter of 6À0 to 10À5. The ionic polymer amounts to 0À1 to 20% by weight of the organic liquid, and comprises a hydrocarbon backbone and from 0À2 to 10 mole per cent of pendant carboxylate, sulphonate or phosphonate groups, neutralized to the extent of 50 to 500% with a basic compound of Group I (A or B) or Group II (A or B) of the periodic table or Pb, Sn or Sb. The cosolvent amounts to 10 to 600 moles per mole of pendant ionic group, is soluble in or miscible with the organic liquid, and has a solubility parameter at least one unit greater than that of the organic liquid and between 10 and 20. The term "solubility parameter" is defined by reference to the literature. The cosolvent may be an alcohol, an amine, an ether or an ester. A list of organic liquids is given, and includes hydrocarbons, ketones, halohydrocarbons, mineral lubricating oils, ethers, esters, polymeric oils and synthetic lubricating oils. When the organic liquid is a lubricating oil, conventional lubricant additives may also be present. If they have solubility parameters in the range specified for cosolvents, they may partially replace the latter, but may not be used in amount exceeding the limit for cosolvent. The viscosity of the composition changes little with temperature.

Title: Improvements in or relating to the packaging of liquids
Inventor: TEBBUTT ERIC
IPC: B65B9/12
Filed: 1956-06-02
Abstract: 814,325. Packaging-machines. ROSE BROS. (GAINSBOROUGH) Ltd. May, 24, 1957 [June 2, 1956], No. 17106/56. Class 94(1). In a machine in which the longitudinal edges of a folded web or two opposed webs are heatsealed to form a tube which is filled with liquid and then sub-divided by transverse heat seals to form a succession of packages, a substantial head of liquid is maintained in the tube above the transverse sealing portions and, prior to each transverse sealing operation, the tube is nipped above the sealling position to dispace the liquid in the tube, sealing then taking place substantially simultaneously with the release of the nipping pressure. A web 11 of polyvinyl chloride is folded longitudinally by a guide 12 and fed downwardly by a pair of opposed pulling members 14 mounted on carriers 16 each coupled by a toggle linkage 17 to a frame 18 secured to a non-rotatable shaft 19 mounted for vertical reciprocation in a bed 21. Each linkage 17 is pivotally attached to an arm 22 pivoted to the associated frame 18 and having an extension 23 carrying a roller 24 engaging a cam 26 on a rotatable and vertically-reciprocable shaft 27. The carriers 16 also support longitudinal edge sealers 28 and transverse sealers 29 constituted by electrodes to which a high-frequency voltage is applied. The liquid is syphoned from a tank and fed into the tube by a pipe 31 which extends downwardly into the sealed portion thereof a distance equal to the length of several packages. Completed packages are severed from the tube by a cutting device 33 and fall onto a delivery conveyer 34. The frames 18 and linkages 17 are operated to cause the pullers 14 and sealers 28, 29 to engage the tube and then move downwardly to feed a length of tube equal to the length of one package, seal a length of tube somewhat greater than the length of a package and form a transverse seal. As the carriers move outwardly and upwardly after the completion of these operations, a pair of cam-operated nipping members 36 are moved slowly into engagement with the tube to displace liquid in readiness for the next sealing operation, the nipping pressure being released substantially simultaneously with the reengagement of the tube by the sealers 29. Violent upward surges of the liquid, which might cause frothing, are their eliminated.

Title: Toy vehicle with spring-actuated drive
IPC: A63H17/00
Filed: 1954-06-11
Abstract: 747,157. Toy vehicles. ERNST, M. June 11, 1954 [June 15, 1953], No. 17165/54. Class 132(3) Two wheels or two pairs of wheels of a toy vehicle may be driven from a clockwork mechanism, and either or both of the wheels or pairs of wheels may be disconnected from the drive, the toy thus being controllable to run straight ahead, turn in a curve or remain stationary. In a toy aeroplane having a tricycle type undercarriage, pairs of wheels 27 may be driven from a mechanism 4 and hand levers 45, 46 each control drive to a wheel pair. When the levers are moved forwardly, shafts 21, 22 are urged upwardly and rearwardly by flexible drives 29, 30 connecting the shafts with two outer propellers and pinions 19, 20 on the shafts are driven via a, pinion 14 and gear 13. Wheel pairs 27 are thus both driven from shafts 21, 22 via gears provided in each undercarriage member 1, 2, and all four propellers are driven. On moving the lever 45 rearwardly, the drive from the pinion 14 to pinion 19 is' disengaged causing drive to the propeller 33 and to wheels of the undercarriage 1 to be disconnected; the toy is thus made to travel to the left by the still driven pair of wheels 27 of the undercarriage 2. Rearward movement of lever 46 produces a corresponding right turn of the toy and drive to the other outer propeller is disconnected. With the levers 45, 46 both in the rear position, only the propellers 18 are driven and the toy is stationary. A hand lever 11 enables the clockwork mechanism to be stopped and started.

Title: Improvements in yielding shaft-couplings
IPC: F16H33/08
Filed: 1924-07-18
Abstract: 240,259. Burgess, S., (Tekniske Forsogsaktieselskab). July 18, 1924. Shaft couplings. - A yielding shaft coupling comprises a centrifugal mass connected to arms or discs on the shafts bv means which act to alter its radius of rotation in response to changes of torque. Crank pins C, D carried by the aligned shafts A, B are connected by a flexible cable, chain, or toggle links F, G, Fig. 5, an additional weight or weights M being provided if necessary. The torque is balanced by the components K<1>, K<2> of the centrifugal force K, the magnitude of these forces depending on the angle a between the links F, G. Under overload or on starting, theflexible connection between the pins C, D straightens out and conveys a rigid drive. The arrangement is preferably duplicated to secure balance. In another form arms M<1>, Fig. 8, carrying masses M are extended beyond the pivoted pins D and connected by links 0 to the pins C on the arms S. In a modification, the ends of the arms S are slotted to engage pins on the arms M<1>, which are then not extended. In the form shown in Fig. 13, the shafts carry interfitting drums C<1>, D<1> forming a casing. Segmental planetary wheels L, rotatably mounted on the drum D<1>, carry masses M and mesh with a pinion N on the other shaft. Leather buffers Z, rigid with the part D', limit the movement of the masses M and provide for solid drive. By making the pinion N small in comparison with the wheels L, considerable angular displacement between the coupled shafts is possible. The wheel N may, however, be internally toothed to gear with the wheels L.
