Title: Break-in fuel and method for breaking in internal combustion engines
IPC: C10L1/12
Filed: 1944-08-16
Abstract: Internal combustion engines are run in by operating them with a gasoline fuel containing an amount of iron carbonyl insufficient to raise materially the anti-detonation value of the fuel. Thereafter, operation of the engine may be continued on a standard or regular gasoline free from iron carbonyl.  The gasoline to which the iron carbonyl is added may be straight run, cracked or synthesized (as by alkylation or polymerization of olefins or other suitable hydrocarbons) or may be a blend of several components and may contain tetraethyl lead, aromatic amines of not more than about 9 carbon atoms, other additives to raise anti-knock value or to adjust volatility or both, and oxidadation inhibitors.  Aromatic amines mentioned are aniline, toluidine and xylidines while oxidation inhibitors specified are 2 : 4-dimethyl-6-tertiary butyl phenol, 2, 6-di-tertiary butyl-4-methyl phenol, 2, 4-dimethyl-6-octyl phenol, secondary butyl para-amino phenol, N, N1-di-secondary butyl p-phenylene diamine and N, N1-dipropyl-p-phenylene diamine. A run-in fuel comprising straight-run gasoline, isopentane, tetra-ethyl lead and iron carbonyl is described.

Abstract: 1,004,834. Hydrostatic transmissions; change speed gear. MASSEY-FERGUSON Inc. April 25, 1962, No. 15682/62. Headings F2C and F2D. A motor vehicle transmission comprises an enginedriven continuously variable hydrostatic gear 35, with a variable stroke pump 39 and a reversible constant stroke motor 42 on output shaft 38, a separately and constantly engine - driven power take-off shaft 25, and a combining planetary gear with a ring gear 71 driven by the power take-off shaft 25, a sun wheel 70 on output shaft 38 and, carrying planet wheels 74, an output shaft 75, which is either connected directly or, for industrial tractors, through planetary reversing gear to output shaft 17. The planetary reversing gear provides direct drive when hydraulic disc clutch 84 locks the planetary gear train or reverse drive when brake band 76 holds ring gear 81 stationary the planet carrier 78 carrying pairs of intermeshing planet wheels 80 the wheels of each pair also meshing respectively with the sun gear 77 and ring gear 81.

Title: Transparent films from linear propylene high-polymers
IPC: B29D7/01
Filed: 1957-05-17
Abstract: Films which have a transparency of at least 95%, i.e. they are capable of transmitting 95% of normally incident white light without scattering, are made by extruding a molten linear high molecular weight crystallisable polymer of propylene, alone or in admixture with a linear high molecular weight amorphous or block polymer of propylene, to form a film, and immediately quenching the film in a cooling fluid having a temperature of not more than 80 DEG C.  By blockpolymers are meant polymers which consist of macromolecular isotactic and non-isotactic segments and are soluble in heptane and insoluble in ether.  The quenching fluid is preferably water and the film is obtained by conventional means, e.g. by extruding the fused mass through a die plate and passing the film between a pair of rollers immersed in water. Specification 835,038 is referred to.

Filed: 1952-06-23
Abstract: 696,876. Fish, beheading and gutting. ARENCO AKTIEBOLAG. June 23, 1952, No. 15796/52. Class 28 (ii). Fish are conveyed broadside on to a pair of beheading rotated co-operating wheels 12, 13 having a higher velocity than the conveyer at the cut-off point and spaced so that the tough gullet will pass uncut between the knives. The head is then forced down away from the body by the pockets of a side conveyer 14, as it curves round its sprocket 19, so that the attached gullet, abdomen and foremost end of the gut can be pulled out from the body by gripping rollers 33, 35. The body is held against this pull by a thin plate 40 extending beyond the cutting point and secured to an arm 25. The cutting wheels 12, 13 each mounted on its swingable arm 20 or 25 are adjusted by a handle 39 operating eccentrics 34 whereby both cutting wheels can be raised to suit thicker fish. The spacing apart of the knives can be adjusted each independently by a screw 50 for each arm 20, 25.

Abstract: 277,751. Vickers, Ltd., and Lucas, O. D. June 24, 1926. Fire between aircraft propeller blades, controlling and synchronizing.-Mechanism of the kind comprising a cam driven from the propeller shaft and acting on a spring-controlled member which is connected to a sear-operating member, is provided with a device for positively preventing the sear-operating member from moving except when the breech is closed. As shown in Figs. 1, 3, and 5, the rotating cam B acts on a spring-controlled lever 0 pivoted to a sliding bar D which is adapted to operate the sear A<2> through a cranked lever F, F<2>. The compression spring C<2> acting on the lever C is connected at one end to an eccentric pin E<x> on a disc E<1> adapted to be rotated, by operating the firing lever or trigger, to move the lever C from the inoperative position shown in Fig. 1 to the operative position shown in Fig. 3. The disc E<1> also carries, on another eccentric pin E<2>, a safety catch E adapted to engage a notch D<1> in the operating bar D to lock it until the firing lever has been operated. The device for locking the operating bar except when the breech is closed, comprises a spring plunger A<4> engaging a notch D<2>, Fig. 5, in the underside of the bar. This plunger is depressed, when the breech is closed, by another plunger A<3> acted on by the side lever A<1> of the gun lock. When the bar is locked, the cam B merely displaces the lever C against the resistance of its spring. When the breech opens, the lever F and the bar D are restored to their original positons by the gun lock acting on a tail portion F<3> of the lever and on a cranked lever G, G<1> connected to the bar. In a modification, Figs. 7 and 12, the spring-controlled arm C, connected to the operating bar D, is operated indirectly by the cam B, Fig. 12, through a plunger B<1>, arm B<2> and Bowden wire B<3>. The disc of the first construction is replaced by a three-armed lever of which one arm E<x> is connected to the spring C<2>, another arm E<1x> to a Bowden wire E‹ connected to the firing lever, and the third arm E constitutes a safety hook for engaging a pin D<1> on the bar.

A photographic camera has an automatic aperture adjustment for daylight and flash-light exposures dependent upon the position of an indicator 1c, Fig. 2, of a photo-electric exposure meter. A battery 3 Fig. 1, switched into circuit with meter 1 by switches 4, 5 for flash-light operation (as indicated by flash symbol), which a photo-cell 2 is switched into circuit by the switches 4, 5 for daylight operation (as indicated by the sun symbol). Two potentiometers 8, 9 in series are set in accordance with focus setting and intensity of a flash-light source respectively: The potentiometer 8, Fig. 2, is associated with focus scale 16 by a sliding contact 18, while potentiometer 9 is associated with scale 17 carrying flash-light values by shading contact 19. The scale 17 is coupled to exposure time scale 22 by coupling 21. Scale 22 carries a film sensitivity scale 22c co-operating with a mask 24a on setting device 24 having teeth 24b engaging a pinion 26 of a gear train including pinion 27 engaging teeth 1a attached to meter body 1b for adjusting the meter 1 consequent upon adjustment of scale 22 and device 24 for exposure time and film sensitivity. Daylight operation Setting device (32), Fig. 3 (not shown) is moved to the "Auto" position as shown by the sun symbol after selecting an exposure time. The meter 1 is thus energized through switches 4, 5, Fig. 1, such that indicator 1c, during release of the shutter and in co-operation with a scanning cam controls the setting of an appropriate aperture. Flash-light operation Setting device is set into "Auto" position as shown by the sun symbol and the exposure time is set on scale (22) Fig. 3 (not shown), e.g. 1/30 for flash-lamp exposure on 1/500 for electronic flash. The meter 1, Fig. 2, is rotated through the gear train including pinions 26, 27 and such rotation is compensated by moving knob 25 and contact 19 to adjust potentiometer 9. An appropriate voltage is applied to meter 1 to automatically adjust the diaphragm setting. The diaphragm setting may also be set manually by adjustment of device 32 to a value on the aperture scale 32a and adjustment for the required focus (scale 16) and exposure time (scale 22).
