Abstract: 367,541. Force-feed lubricators. TACKLIND, S. M. Z., 30, Kungsgatan, Stockholm. Feb. 2, 1931, No. 3287. Convention date, Sept. 13, 1930. [Class 12 (iii).] Apparatus for supplying lubricants, such as oils and fats, under pressure includes means which are especially adaptable as the low pressure part of a high pressure lubricator, but which may be used alone, such means comprising a feeding body 8 performing a rolling movement on the lubricant in a container 1, to force the lubricant through an annular sieve 5 and grooves 4 into ducts 2. The ducts 2 form the supply pipes of a number of reciprocating pumps (not shown) arranged around a driving shaft 3 and connected therewith through gear or worm wheels so as to operate in succession. The feeding body 8 is of double conical form and is freely mounted on an inclined shaft 16 having a bayonet connection 13 with the driving shaft 3, and has also a rolling connection with the base of the container by toothed gearing comprising pins 9 on the base meshing with pins 10 in a groove in the body 8. The upper spherical surface of the body 8 underlies a complementarily shaped ledge on an inserted member 6 so that as the shaft 3 rotates, the body 8 rolls over the lubricant in the compressing space, simultaneously having a backward movement relative thereto, due to the action of the toothed gearing 9, 10. In order to cut off portions of the lubricant in the container and feed them through the crescent-shaped space into the compressing space, the shaft 16 carries a curved sickle-shaped vane 12 sharpened on its leading edge. The vane extends above a conical ledge 19 contiguous with the upper surface of the member 6. The inclined shaft 16 also carries beneath the securing nut 15 a scraper 18 to remove lubricant from the upper surface of the feeding body 8. A space is left between the lower surface of the body 8 and the base of the container to avoid damage due to the presence of hard bodies. The annular sieve 5 is carried on the inserted member 6 and prevents air bubbles reaching the high pressure pumps.

Title: Corrosion inhibiting compositions
IPC: B01J19/00
Filed: 1946-02-04
Abstract: Corrosion inhibiting lubricants and temporary protective coatings for metals comprise a homogeneous storage-stable solution in a non-volatile hydrocarbon medium of a corrosion-inhibiting amount of an organic acid partial ester, of a polyhydric alcohol, the ester portion of which has an aliphatic or cyclo-aliphatic radical and an oil-soluble salt of an organic sulphonic acid, e.g. sodium mahogany sulphonate, in an amount sufficient to maintain the ester in solution under normal storage conditions.  The ester has the following properties: a melting point below about 200 DEG  F., a solubility in the hydrocarbon medium insufficient to enable all the corrosion-inhibiting amount of the ester to dissolve completely at normal room temperature in the absence of a mutual solvent, a ratio of hydroxyl to ester radicals of at least 1 : 1, a content of at least 12 carbon atoms and of at least 2 hydroxyl radicals separated from each other by not more than 3 directly connected carbon atoms. The melting point of the ester may be below about 100 DEG  F., it may contain two hydroxyl radicals attached to adjacent carbon atoms or it may contain hydroxyl radicals and ester linkages attached to directly connected carbon atoms.  The ester may be a glyceryl mono ester, the acid radical being, for example, an oleate, naphthenate or tallate, or the ester may be a sorbitan mono ester of a fatty acid, e.g. sorbitan mono stearate, sorbitan being partially dehydrated sorbitol. Alternatively, the ester alcohols may be derivatives of erythritol, pentaerythritol, mannitol or sorbitol.  The acid radical should have at least 10 and preferably between about 10 and 40 carbon atoms.  A number of suitable acid radicals are given in the Specification.  The proportion of ester present may range from about 0.5 per cent to about 10 per cent by weight and the ratio by weight of the sulphonic acid salt to the ester may be between about 3 : 1 and about 1 : 20. The metal in the sulphonate may be an alkali metal p  such as sodium, an alkaline earth metal or ammonia, and the sulphonate may be a mahogany sulphonate or may be derived from alkyl benzenes, alkyl naphthalenes, coal tars, or obtained by the treatment of aliphatic or cycloaliphatic hydrocarbons with chlor-sulphonic acid. Alternatively, oil-soluble sulphonates of dicarboxylic acid esters such as malonic acid esters may be employed.  The hydrocarbon medium is preferably a liquid, e.g. a refined mineral lubricating oil, but may be a plastic solid such as petrolatum, paraffin wax, or a soap-thickened lubricating grease.  The composition may be incorporated in motor oils in order to produce rust-inhibiting lubricants for internal-combustion engines.  In an example, 4.5 per cent by weight of glyceryl mono oleate and 0.4 per cent by weight of a 50 per cent concentrate of sodium salts of mahogany acids are added to a refined mineral lubricating oil of 740 S.U.S. viscosity at 100 DEG  F.

Title: Speed-responsive systems
IPC: G01P1/10
Filed: 1971-02-01
Abstract: 1386961 Automatic control of speed ASSOCIATED ENG Ltd 25 Jan 1972 [1 Feb 1971] 3640/71 Headings G3P and G3R A speed responsive system for a power unit 11 driving a shaft 12 is particularly applicable to vehicles and includes an inductive transducer 14 receiving impulses from a ferrous-toothed disc 13; a frequency-to-voltage converter 16 whose output is proportional to the frequency of the rotating disc; a comparator 21 fed from the converter 16; a differentiator 23 and reference voltage points 29, 26,; and two torque changing systems an increase system 30 and a decrease system 31 which operate a throttle actuator 32 in response to pulses from comparator 21. The reference voltage may be supplied from a potentiometer 29 or a memory circuit 26. A voltmeter 19 and a pulse counter 18 calibrated to indicate shaft speed or revolution numbers respectively or in the case of a vehicle road speed and distance respectively are included in the circuit. The memory circuit is set by closing switch 25 momentarily with the shaft running at the required speed to generate the corresponding reference voltage. The differentiator has the effect of stabilizing the system by filling in the dead band between the torque increase and decrease control modes. The control circuitry also includes feedback loops R30-D5-C10 and R31-D6-C11 from the output of the units 30, 31. The circuitry arrangements are shown in Fig. 2. Fig. 3 (not shown), illustrates the switching mechanism connecting the circuits of Fig. 1 to the power supply and controlling the modes of operation of the regulator. This mechanism is under operator control and may include drop-out contacts which respond to clutch or brake operation. Figs. 4-10 show various mechanical and hydraulic devices which respond to the output of the units 30, 31 [Figs. 4 and 5 only shown in abridgement.] These may operate the throttle directly, act as a limit device, or act to merely give a warning signal. In particular, in Fig. 4., when the system is set to Auto relay RLB operates to move valve 49 to close air bleed 50. When a torque increase voltage appears at terminal U valve 51 opens to admit manifold vacuum to chamber 48 causing bellows 45 to retact and open throttle 41. If a torque decrease voltage appears at U air is admitted via valve 53 to cause throttle to close. Fig. 5 shows an equivalent system using hydraulic circuit rather than pneumatic. In this embodiment the throttle pedal 58 is hydraulically linked to the throttle but is over-ridden by the automatic control of the fluid pressure in the system when set to Auto. The throttle opens in response to pump 59 and closes in response to relief valve 68.
