Title: Bituminous compositions
IPC: C08L95/00
Filed: 1957-09-09
Abstract: Copolymers of glycidy polyethers (1.2 epoxy equivalency greater than 1) of a polyhydric phenol with a polymerized conjugated fatty acid are obtained by precondensing the epoxy compound with the acid by preliminary heating in the absence of a catalyst, adding the catalyst, and further heating.  For example, trimerized 9,11 octadecadienoic acids and liquid glycidyl polyether of 2,2 bis (4-hydroxyphenyl) propane are heated at 100 DEG  C. and alpha methyl benzyl dimethylamine (as catalyst) then added with further heating at 100 DEG  C.  Specified phenols for preparing the polyethers are resorcinol; methyl resorcinol; catechol; hydroquinone; 4,41-dihydroxy benzophenone; bis (4-hydroxyphenol) methane; 1-1 bis (4-hydroxyphenyl) ethane, and isobutane; 2,2 bis (4-hydroxyphenyl) butane; 2,2 bis (4-hydroxy-2-methyl phenyl) propane; 2,2 bis (4-hydroxy 2-tertiary butylphenyl) propane; 2,2 bis (2-hydroxynaphthyl) pentane; and 1,5 dihydroxynaphthalene. The polymerized acids are prepared by heating, e.g. their lower aliphatic esters, and the monomer acids preferably have 16 to 24 carbon atoms, e.g. linoleic, linolenic, eleostearic and licanic acid.ALSO:A bituminous composition consists of an asphaltic bitumen and a copolymer of a glycidyl polyether, having a 1, 2 epoxy equivalency greater than 1, of a polyhydric phenol with a polymerized conjugated fatty acid.  Between 0,5 and 75 per cent. of copolymer can be present.  Preferably the epoxy and acid compounds are precondensed by heating in the absence of a catalyst the bitumen being present or not.  Subsequently, heating is continued in the presence of a catalyst e.g. an amine.  Amongst the phenols specified are mononuclear, e.g. resorcinol, and polynuclear ones, e.g. bis-phenol, the preferred polyethers being prepared from bis phenol.  The polymerized acids are obtained from conjugated fatty acids by heating under known conditions, the monomers containing 16 to 24 C. atoms.

Filed: 1968-11-06
Abstract: 1,240,809. Combustion chambers. TOYOTA CENTRAL RESEARCH & DEVELOPMENT LABORATORIES Inc. Nov. 6, 1968 [Nov. 18, 1967], No. 28853/70. Divided out of 1, 240, 518. Heading F1B. The subject-matter of this Specification is similar to that described in Specification 1, 240, 518, but in the present invention the tube 25 connecting the carburetter A to the auxiliary combustion chamber 21 of the I. C. engine cylinder 1, is provided with a venturi 18 connected to a fuel chamber in the carburetter by a pipe 19. Moreover, the carburetter has only one throttle valve 11, and the inlet valve 30<SP>1</SP> of the auxiliary combustion chamber may open automatically in response to a pressure difference between the tube 25 and the auxiliary combustion chamber. Thus during suction at noload, i.e. with the throttle valve 11 closed, the flow through tube 25 is enriched by fuel drawn through the pipe 19. At part-load the enriching effect is reduced, and at full-load the auxiliary combustion chamber receives substantially all of its mixture via the main combustion chamber since the valve 30<SP>1</SP> remains closed. The valve 30<SP>1</SP> may be replaced by a valve actuated by valve gear to open and close with the main inlet valve 6.

Operation of the lever 20 closes the control valve 15 allowing the pump to cause the ram to tip the vehicle body. Tipping causes the arm 23 to move and gradually open the control valve 15 to arrest the tipping.
Patent GB-395685-A (GB)
Title: Improvements in sound-reproducers
IPC: G11B17/02
Filed: 1931-10-17
Abstract: 395,685. Sound recording and reproducing apparatus. ACH, N., 62, Hainholzweg, and WILICHOWSKI, G., 24, Gronerstrasse, both in G÷ttingen, Germany. Oct. 17, 1931, No. 28879. Convention date, June 27. Void [Published under Sect. 91 of the Acts]. [Class 40 (ii).] Comprises means whereby during sound recording or reproduction the speed of relative motion between the sound recording or reproducing device and the record carrier can be made to vary to produce special acoustic effects. Fig. 1 illustrates the application of the invention to the reproduction of sound from a disc record carrier 4 by an electric pick-up 6 which energizes a loud-speaker 31. The pick-up 6 is pivoted on a spindle 8 to an arm 9 fixed to a casing 10 mounted on a lever 11. The lever 11 is pivoted in a bearing 13 and carries a spring blade 17 fitted with a contact-piece 18. Adapted to engage with the contact-piece 18 is a contact 24 on an arm 23 of a lever 20 which can be turned, about a pivot 19, between stops 21, 22. When the lever 20 is placed against the stop 22, the contacts 18, 24 complete the circuit of an electromagnet 27 which attracts the lever 11 to turn it about the pivot 12 and so impart a limited movement to the pick-up 6 in a direction opposite to that in which the record-4-.is-revolving. Opening of the contacts 18, 24 causes the lever 11 to return to its original position and an oscillatory movement is thus imparted to the pick-up 6. A resistance 26 can be varied by a lever 28 to adjust the strength of the current which energizes the electromagnet 27 and so vary the speed at which the lever 11 is moved. A knob 15 allows of manual operation of the lever 11. As applied to an optical sound recording or reproducing apparatus, Fig. 2, a light source 33 is oscillated longitudinally of the uniformly-moved sound film 32. For this purpose, the light source 33 is suspended from levers 36, 37, the lever 37 having a pin-andslot connection with a connecting rod 40 attached to an eccentric 42 on the shaft of a driving motor 41. The extent of the movement is regulated by adjusting the position of a rod 43 which is adapted to slide in a friction guide 45 and is connected pivotally to the rod 40. The speed of the motor 41 may be varied by adjusting the position of a lever 47 which slides over a resistance 46. In an alternative form, the film is passed at the sound head over a roller which is rotated, by means of a pawl-and-ratchet mechanism, first in a forward and then in a backward direction to accelerate and retard alternately the motion of the film.
