Title: Improvements in or relating to the preparation of heavy duty lubricating grease
Inventor: MORWAY ARNOLD JESSE
IPC: C10M169/00
Filed: 1950-09-06
Abstract: A lubricating grease comprises from 30 to 60 per cent. by weight of an asphaltic residuum having a viscosity of from 1000 to 5000 s.s.u. at 100 DEG F., 20 to 50 per cent. by weight of a mineral lubricating oil having a viscosity between 35 and 300 s.s.u. at 210 DEG F., 8 to 18 per cent. by weight of an alkali or alkaline earth metal soap of fatty acids having 12 to 22 carbon atoms in the molecule and 1 to 15 per cent., preferably 6 to 12 per cent., by weight of an extreme-pressure additive.  The composition is non-brittle at temperatures below 0 DEG F. and remains solid up to 250 DEG F.  The asphaltic residuum preferably has a viscosity of 2500 s.s.u. at 100 DEG F.  The preferred alkali or alkaline-earth metal soap is the sodium soap of rapeseed oil, but sodium stearate or calcium stearate may also be used.  Lead oleate is the preferred extreme-pressure agent, and may be used in an amount of about 10 per cent. Conveniently it may be added as a 50-50 solution in mineral soil. Chlorinated and/or sulphurized fatty oils or hydrocarbons may also be used as extreme-pressure agents.  From 0.05 to 1 per cent., preferably about 0.2 per cent., based on the total composition, of an oil-soluble sodium petroleum sulphonate, preferably of molecular weight 450 to 500, may also be added, to inhibit rust-formation. Other known corrosion inhibitors such as partial esters of polyhydric alcohols may be used in place of the sodium petroleum sulphonate. The petroleum sulphonate is preferably added after the grease has been cooled from its maximum temperature.  Other additives such as antioxidants, rust inhibitors, viscosity index improvers, tackiness agents and polymeric thickeners may be added if desired.  In an example a grease composition is prepared from 8.8 per cent. by weight of rapeseed oil, 1.9 per cent. of caustic soda, 29.1 per cent. of low and cold-test mineral oil of 50 s.s.u. viscosity at 210 DEG F., 0.2 per cent. of sodium petroleum sulphonate of molecular weight 450 to 500, 40 per cent. of asphaltic residuum of 2500 s.s.u. viscosity at 100 DEG F., and 20 per cent. of a 50 per cent. solution of lead oleate in mineral oil.

Patent GB-1185990-A (GB)
Title: Automatic gain control, notably for televisors
IPC: H04N5/53
Filed: 1967-05-15
Abstract: 1,185,990. Automatic gain control. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 15 May, 1967 [18 May, 1966], No. 22336/67. Heading H3T. In an arrangement in which automatic gain control is derived from the alternating voltage component of a composite video signal in a transistorized television receiver a threshold current device controlled by current variations in one of the amplifier stages is provided: the device so modifies the automatic gain control as to prevent saturation of certain stages of the receiver occurring. The receiver comprises an I.F. stage T1, the gain of which is controlled by variation of base bias and a video signal amplifier including an emitter-follower T2 coupling the detector to an amplifying stage T3: the emitter circuit of the latter comprises a frequency-correcting inductor L2 shunted by variable resistor R19. The collector circuit of transistor T3 comprises frequency-correcting inductor L2 and a resistance network R6, 7, 8 and feeds the picture tube by means of line K. At the join of resistors R7, 8 a video signal is taken off and the A.C. component applied via capacitor C3 to transistor T4 which is biased to act as a detector, the bias network comprising resistors R9, 10, 11 and a potentiometer P1 which comprises the contrast control. The D.C. output at the collector of transistor T4 is smoothed by capacitor C4 and applied to the base of a D.C. amplifier comprising transistor T5, the collector potential of which comprises the gain control voltage and is applied to the base of transistor T1 and to other stages via line CA s . In such an arrangement the gain goes to its maximum value if the modulation disappears, causing saturation of the receiver which removes any modulation when this is again present, so that A.G.C. cannot take control. To prevent this, the D.C. potential at the common point of resistors R6, 7 is applied to the base of an auxiliary transistor T6, the collector of which is coupled via diode D1 to the common point of resistors R14, 18 in the base circuit of transistor T5. Normally transistor T6 is biased to a saturated condition, diode D1 is non- conductive, and it has no influence on the operation of the A.G.C. circuit: in the absence of modulation, the increased D.C. level at transistor T3 causes the base potential of transistor T6 to fall, so that it is biased back. The collector potential then rises, diode D1 becomes conductive and a positive potential is applied to the base of transistor T 5 , causing its collector potential to fall and bias back the A.G.C. line.

Title: Improvements in or relating to implements for paring and slicing beans
IPC: A47J17/06
Filed: 1944-11-13
Abstract: 597,642. Slicing vegetables. ROBINSON, F., and JACOBSON, J. Nov. 13, 1944, No. 22376. [Class 5 (i)] A kitchen implement for slicing and paring beans comprises a frame, a feed channel formed in two parts, one of such parts being integral with or rigidly secured to the frame and the other of such parts being resiliently secured to the frame so as to be movable towards and away therefrom a cutting member 14, on each part of the channel adapted to pare the longitudinal edges of the beans passed therethrough, a separate cutting member 18 formed integrally with or secured rigidly to the movable part of the feed channel, and a second feed channel with cutting means mounted in the frame wherein a pared bean may be sliced. In the construction shown, a rectangular frame 1 of sheet metal strip is secured to a table by clamping means 2, 3, of known type, the longer edges of said frame being vertical. A cross-bar 6 secured to the frame has a feed channel 7 mounted thereon, a series of equally spaced slicing knives 8 being supported in said channel and extending entirely across its width, their cutting edges being arranged in a curve when viewed in plan. A strip 11 has a central depression 12 with guide posts 13 mounted on each side of said depression, said posts passing through apertures in a member 9, which also has a depression 10 along its length, so that both depression 10 and 12 together form a feed channel and each has a paring knife 14 mounted centrally. Apertures in the cross-bar 6 serve as guideways for the extremities of the posts 13, and helical springs 15 surrounding said posts and abutting against lugs 16 and the inner faces of the members 9 serve to urge the strip against the said members 9. Knife edges 18 on a V-shaped portion of a strip 17, mounted on the upper face of the strip 11, serve to remove the tips of the beans.

Title: Improvements in or relating to welt turning mechanism for straight-bar knitting machines
Inventor: FORD BENJAMIN HARVEY
IPC: D04B11/32
Filed: 1958-07-12
Abstract: 874,991. Knitting-machines. MONK (SUTTON IN ASHFIELD) Ltd., S. A. Oct. 12, 1959 [July 12, 1958], No. 22415/58. Class 74 (2). The welt hook bar 9 of a straight bar machine is supported at its ends by members 8 pivoted on slides 4 movable along arms 1 pivoted on a shaft 3, the slides being moved along the arms, for the hooks 10 to take loops of the first course, and withdrawn to take up the work as it is produced; and, to turn the welt, the arms 1 and slides 4 are moved and the members 8 are turned about their pivots so that the hooks 10 are substantially vertical and engage and move in co-operation with the needles for the return thereto of the loops. The slides are moved along the arms 1 by rotation of a shaft 7, to which they are connected by links 5 and arms 6. The members 8 are pivoted by rotation of a shaft 17 acting through arms 16 and links 15 having slots 14 in which engage pins 13 on arms 12 on the members. The slots 14 are long enough to allow for advance and withdrawal of the welt bar. The necessary up and down motion of the welt bar is obtained by raising and lowering the arms 1 by rotation of the shaft 3, to which the arms are connected by arms 43, links 44, bell cranks 45 and links 46. The shafts 3, 7 bear pinions through which they are rotated by racks reciprocated by cams on the main shaft. The trucks which co-operate with these cams are moved into and out of engagement therewith by forks on rods 32, 26, slid longitudinally under pattern control. The shaft 17 is turned by another cam acting through a truck, under the control of the rod 32 and link work. The in and out motions of the needle bar, necessary for the return of the loops to the needles, are produced by yet another cam acting through a truck moved into and out of engagement with it by a third slidable rod 41. The rods are slid or not according as to whether their ends miss or hit holes in a disc 56 when it is advanced towards them. The disc is rotated under pattern control. Each link 5 is of two telescoping parts connected by a spring which is extended as the shaft 7 returns to its starting position after the welt hooks are engaged with the loops; and the spring then provides the draw-off tension. The shafts 3, 7 may alternatively be turned, to raise and lower the arms 1 and to move the slides 4 longitudinally thereof, by means similar to means described in Specification 787,994. Each welt hook has a flute 19 and an offset stem forwardly thereof.

Title: Improvements relating to blends of olefin polymers and waxes
IPC: C09D191/08
Filed: 1965-05-26
Abstract: Blends of polybutene-1 and a petroleum wax are obtained by mixing butene-1, a petroleum wax and a catalytic amount of a catalyst formed by mixing a compound of a metal of Group IVb, Vb, VIb or VIII, Large's Table, or manganese with an organometallic compound of an alkali metal, an alkaline earth metal, zinc, an earth metal or a rare earth metal, and heating the resulting mixture to a temperature of 50 DEG  to 160 DEG  C. under a pressure from atmospheric to 17.5 kg./cm.2.  Excess catalyst is preferably removed from the polymerization mixture by adding water, the amount being insufficient to wet the polybutene-1 was blend, and then removing the catalyst residues, e.g. by filtration.  Paraffin waxes, e.g. mixtures of essentially straight chain hydrocarbons or intermediate fractions containing straight chain n - paraffins, isoparaffins, polycyclic paraffins and aromatics or the micro-crystalline waxes consisting of a mixture of isoparaffins, polycyclic paraffins and aromatics, may be used. The molecular weight of the polybutene-1 can be controlled by varying the polymerization temperature, adding zinc diethyl or adding hydrogen.  In the examples the catalysts employed are titanium trichloride with either diethyl aluminium chloride or triethyl aluminium.

Abstract: 959,567. Transformers and inductors; electric conductors; electric coils. REYNOLDS METALS CO. June 27, 1960, No. 22457/60. Headings H1A, H1P and H1T. [Also in Division H2] A conductor, which may be wound into a coil such as 10, for transformers, comprises layers of insulated and uninsulated strips, e.g. 13, 15, of aluminium and/or copper, such that the insulated strips are thin and can readily be coiled without cracking the insulation. The insulation 14, e.g. of aluminium oxide, may extend over one face, where the uninsulated strip 15 touches the uninsulated face, Fig. 2, or both faces, Fig. 4. In the first case the strips form a single conductor between terminals 11, 12 and in the second case they may form separate circuits. The bare strips are narrower but of greater section from the insulated ones, and the insulation 14 extends over the edges of strips 13 to prevent edge arcing. A coil with three separated conductors has a completely insulated strip 47, a half-insulated strip 48 and a bare strip 51. Multiplication of the uninsulated strips increases the area of the conductors for heavy duty. In this case, extra bare strips may contact the uninsulated face of the halfinsulated strip (Fig. 6a, not shown).

Abstract: 670,671. Saw-tooth generating circuits; integrating circuits. GENERAL ELECTRIC CO., Ltd. Aug. 21, 1950 [Sept. 2, 1949], No. 22807/49. Class 40 (vi). An integrating or saw-tooth generator circuit comprises a Miller valve the anode of which is connected via a diode to a further valve and means for biasing an electrode of each valve to render each non-conducting so that the Miller capacitor is rapidly re-charged at the end of its linear " run-down period via the diode and a low value resistor in the anode circuit of the further valve. The Figure shows a saw-tooth generator circuit comprising a Miller valve 1. When switch 11 is opened both valves 1 and 5 are rendered conducting and the anode potential of the Miller valve falls linearly in a conventional manner, diode 7 being non-conducting during this period. At the end of the " run-down " switch 11 is made, so that both valves 1 and 5 are rendered non-conducting, the anode potential of valve 5 rises rapidly and diode 7 conducts. Capacitor 4 is thus re-charged very rapidly via diode 7 and the low value resistor 6 thus shortening the fly-back period of the saw-tooth output wave form which may be taken between the anode and cathode of the Miller valve 1. When the circuit is used as an integrating circuit the voltage to be integrated is applied between the control grid and cathode of valve 1.
