Abstract: 668,745. Liquid seals. ROCKWELL MANUFACTURING CO. Nov. 14, 1949. No. 29109/49. Class 122(v). [Also in Group XXIX] A method of maintaining a fluid tight seal for a bearing space between two relatively movable parts comprises providing a body of plastic lubricant, containing a stable dispersion of small discrete bubbles of compressible gas, in communication with the said space, storing energy in the lubricant by compression thereof and utilizing this energy for displacing further lubricant into said space by expansion as the lubricant in the space becomes depleted. The invention is applied to a plug valve, Fig. 1, in which lubricant contained in a reservoir 33 in the valve stem is forced by a screw 37 past double check valve units 35, 36 into a chamber 34 which communicates with four grooves such as 40, 41 in the surface of a plug 15. The lubricant forms a liquid sealing film between the plug and surfaces 13, 14 in the valve body 11. A pressure gauge 60 may be fitted. In another embodiment the chamber 34 is omitted and the grooves are formed in the bore of the body 11 and communicate with the reservoir in the stem through arcuate grooves in the surface of the plug. A grease gun may be used instead of the forcing screw.

Title: Improvements in manufacture of carbon black
IPC: C09C1/50
Filed: 1962-08-03
Abstract: <PICT:0991428/C1/1> <PICT:0991428/C1/2> Carbon black is produced by the thermal decomposition of a hydrocarbon make according to a process in which there is established and maintained within an elongated furnace chamber a stream of hot combustion gases at a temperature in excess of the decomposition temperature of the hydrocarbon make, the make is injected into this gas stream as an expanding, conical spray stream, and this spray is caused to pulsate by rapidly varying the spread angle of the stream so that the hydrocarbon make is rapidly dispersed in the gas stream and decomposed. The frequency of pulsation of the make stream is preferably between 200 and 500 revolutions per minute. The spread angle of the entering make stream is varied from a maximum within the range 60 to 90 degrees to a minimum approaching the symmetrical axis of the make stream. In Fig. 1, a carbon black furnace having coaxial chambers 1 and 5 is fed with a hydrocarbon fuel/air mixture, which may be precombusted, through tangential burner ports 7.  Hydrocarbon feed is axially injected by a nozzle shown in Fig. 4.  The nozzle comprises a tubular feed pipe 20 to which hydrocarbon is fed by line 43, and which is surrounded by an air jacket 22 and two interconnected cooling jackets 24 and 27.  The feed pipe 20 terminates in an end plug 31 having a conical orifice meeting with a cone 34 formed at the end of an axial stem 37.  Oscillation of the latter varies the spread of the hydrocarbon make injected. Specification 834,634 is referred to.

Title: Electric switch for operating the light and sound signals of motor-driven vehicles
IPC: B60Q1/42
Filed: 1928-10-16
Abstract: 299,308. Siegl, S. Oct. 22, 1927, [Convention date]. Road-traffic signals on vehicles. - Dimction signals and audible signals on motor-vehicles are operated by the same switch levers 3, 3<1>, which are provided with abutments 9, 9<1> adapted to cooperate with a stop 10 on the steering-wheel. The levers 3, 3<1> carry spring contacts 5, 5<1> co-acting with two contacts on a fixed piece 4 so as to light the left or right turn signal when the selected lever is turned by hand. The lever is held in this position by a spring catch, but when the steering-wheel is turned to effect the desired turn the stop 10 engages, say, the stop 9 and moves the lever 3 so that its extension 8 closes a contact and sounds a horn signal. The continued movement of the steering-wheel releases the stop 0 and allows the lever 3 to return to its "left turn" notch, thus interrupting the horn signal. The return movememt of the steering-wheel resets the lever 3. To sound the horn alone, the lever 3 is moved in the opposite direction, bringing an extension 7 against the contact for the horn circuit. Extensions 7<1>, 8<1> on the lever 3<1> correspond to the extensions 7, 8. Specincation 293,770 is referred to.

Title: Improvements in apparatus for spreading butter and like substances
IPC: A21C15/00
Filed: 1950-12-08
Abstract: 696,966. Spreading butter. STANDEVEN, J. E. Dec. 6, 1951 [Dec. 8, 1950], No. 30099/50. Class 28 (i). A bread slice from a hopper 4 is slid with a slightly upward incline under a buttering knife 20 and a smoothing knife 27, and is then penetrated by fingers 30 which remove and drop the slice when its carrier block 3 is slid back to receive the next slice. The block 3 slides on inclined guide rails 2 thereby pressing the slice upwards towards the knives 16. The butter is forced by a piston 31 through slots 16, Fig. 1, and 18, Fig. 5, to the knife 20 which can swing about its shaft 21 against the pull of a spring 23 as the slice passes under its edge with a wiping action. The smoothing knife is similarly mounted to smooth the butter and pick up any surplus. The knife 20 is initially pivoted up high enough to clear the crust or edge of the slice by a fixed cam 24 lifting a cam plate 25 on the end of the knife shaft 21. The knife 21 is adjustable for width by making it in three overlapping sections the end sections being slidable behind the middle section and mounted on split shafts 21A secured by lock rings 21B to the split shafts 21. To prevent the knife 20 from applying residue butter to the surface of the slice carrier 3 on its return stroke, it is held up clear by an adjustable bar 6 engaging the cam plate 25. The butter supply can be varied by an adjuster 37, which alters the angular relation of the oscillated offset arm 35 to the fork 36 whereby the rotation of the ratchet 33 is varied thus varying the amount of the screw-down of the piston 31. The rotary oscillation of 15 is derived from the oscillation of the slice carrier. The piston has a one way valve 40 to prevent suction when being withdrawn.
