Title: Improved lubricating arrangement for centrifugal separators
IPC: B04B9/12
Filed: 1934-05-18
Abstract: 422,391. Lubricating. AKTIEBOLAGET SEPARATOR, 8, Fleminggatan, Stockholm. May 18, 1934, No. 15113. Convention date, May 18, 1933. [Class 12 (ii)] [See also Group II] In a centrifugal separator with peripheral outlets 4 to which sludge is conducted by a conveyer in the bowl, the bearing nearest to the bowl is supplied with lubricating oil from a pump or an elevated container. In the form shown in Fig. 1 the oil is conducted from the container 13 by the pipe 16 fitted with an observation glass 14 and valve 15. It passes through the bearing 11 to the trough 17 and thence by the pipe 17a to the oil-bath 30. A branch pipe 18 conveys oil to a bore 19 in the bottom of the frame from which it passes through the axially movable sleeve 20 and the channel 23 in the shaft 9 to the bearing 24, the gear housing 8, and the bearing 25 between the conveyer spindle 5 and the bowl spindle 6. It then passes through the channel 26, the trough 27, and the pipe 29 to the oil-bath 30. The oil overflows from the bath 30 through the bearing 12 and is returned to the container 13 by a pump. In a modification the shaft 9 is provided with a helical thread which acts to pump oil from the bath upwards through the gear housing and the bearings between the bowl and conveyer spindles until it is dropped on to the bearing 11 with the oil from the pipe 16. The Specification as open to inspection under Sect. 91 comprises also the modification shown in Fig. 3 (Cancelled) in which the resilient buffers 41 of the bearing 11 have channels 42 corresponding to channels 43 in the bearing so that oil can be supplied under pressure through the pipe 16 to the surface 44. This subjectmatter does not appear in the Specification as accepted.

Title: New 7ª-methyl-androstenes and process for their manufacture
IPC: A61K31/569
Filed: 1964-04-13
Abstract: The invention comprises steroids of the formula <FORM:1023715/C2/1> wherein R1 is hydrogen or methyl; R2 and R3\t are each hydrogen or C1-18 acyl, or R2 may also be tetrahydropyranyl; and R4 is hydrogen or a C1-4 hydrocarbon group.  They may be prepared by (1) epoxidation of a corresponding 4-unsubstituted-steroid and then splitting of the resulting 4,5-epoxide; (2) hydroxylation of the same starting material and then dehydration of the resulting 4,5-dihydroxy-steroid; (3) exchange of the halogen atom in a corresponding 4-halo-steroid for the group -OR2; or (4) oxidation of the corresponding 4-unsubstituted ring A saturated steroid.  Hydroxy groups in the resulting products may be esterified and esterified hydroxy groups hydrolysed.  The 4-hydroxy and tetrahydropyranyloxy groups can also be interconverted.  Examples are given.  4 - Unsubstituted D 4 - 3 - oxo - 7a  - methyl - androstenes and 19-nor-androstenes are prepared from the 4,7-unsubstituted D 5-3-hydroxy compounds by Oppenauer oxidation, dehydrogenation of the resulting D 4-3-ketones to D 4,6-3-ketones, and reaction of these with methyl Grignard reagents. The products may then be catalytically hydrogenated to the corresponding ring A saturated 4-unsubstituted 3-oxo-7a -methylandrostanes. Corresponding 17-oxo-steroids may be prepared similarly and then converted to the appropriate 17-hydroxy steroids. 3 - Oxo - 4,5 - oxido - 7a  - methyl - 17b  - (b 1 - phenylpropionyloxy)-19-nor-androstene is prepared by esterification of the 17b -ol.  The 7a -methyl-androstenes of the invention, which are stated to be anabolics, and some of which are also stated to show a progestative, ovulation - inhibiting and antigonadotrophic action, may be made up into pharmaceutical compositions with suitable carriers.  These may take the form of tablets, dragees, capsules, solutions, suspensions, emulsions, ointments or creams and may contain preserving, stabilizing, wetting or emulsifying agents, salts for varying the osmotic pressure, or buffers.

Title: Improvements in or relating to improved molds and patterns and method for productionthereof
IPC: B22D25/02
Filed: 1946-05-21
Abstract: 612,446. Moulding and casting processes; mercury &c. patterns. KOHL. E. F. May 21, 1946, No. 15380. Convention date, Aug. 25, 1943. [Classes 83 (i) and 83 (ii)] A method of preparing a foundry pattern for use in producing a mould, comprises introducing mercury into a master mould, freezing the mercury and removing the frozen pattern from the mould. Instead of pure mercury an amalgam which is liquid at ordinary temperature may be used. A master mould comprising two parts 6 and 7 held together by spring means 8 is immersed in a low freezing point liquid such as acetone or ethylene dichloride contained in one compartment 18 of a vessel shaped as shown in Fig. 4. The other compartment 17 contains solid carbon dioxide which cools the liquid sufficiently for it to freeze the mercury which is poured into the mould through a gate. The acetone or ethylene dichloride may be poured into the mould, where it acts as a lubricant and facilitates the withdrawal of the pattern. Alternatively, any suitable form of known refrigerating apparatus may be used. The mould is then opened to release the frozen mercury pattern which is placed in a flask and packed around with moulding material such as ordinary moulding sand. A suitable form of flask, shown in Fig. 7, comprises end plates connected by a spacer and two semi-cylindrical side walls 23, 24 hinged together at 25 and secured by a fastener 26. One of the end plates has a comparatively wide opening to facilitate the packing and ramming of the sand. The flask is then inverted on a stand and the mercury allowed to melt and pass into a collecting vessel through a screen and filter. To remove the last traces of mercury from moulds of complicated shape, the mould is heated to about 700‹ F. at which temperature the mercury volatilizes and may be readily condensed and recovered. Larger and more complicated patterns may be formed from two or more patterns made to fit together by means of integral dowel pins. When assembled, such parts will readily fuse together at the surfaces which have been exposed to atmospheric temperatures. Fig. 18 shows a mould for casting a spring or other helical member formed from a pattern 47, Fig. 17, made by bending a frozen mercury rod around a mandrel. Patterns for making moulds for casting chain links may be made in two interfitting parts 49, 50 as shown in Fig. 19, or, alternatively, may be made as shown in Fig. 25, some of the links being split and after assembling are closed up as at 63, the two ends adhering to form a closed link.

A reciprocating pump for delivering measured quantities comprises a closed bellows 70, loaded by a spring 78, which has its interior connected to liquid in a reservoir 22 through passages 62, 60 and pulsations are applied to the liquid by a piston 23 having an inclined control edge 65 that co-operates with the port 60 to determine the amount of liquid trapped between the piston and the bellows ; the piston is rotated by a knob 55 through pinions 52, 53 to adjust the stroke of the bellows. The piston is'maintained against an eccentric ring 36 by a spring 48 and the bellows 70 has a rod 76 which enters a guide sleeve 77. The pressure of the pulsations is limited by a relief valve. A non-return valve or a valve attached to the bellows is located between the bellows and the piston to ensure liquid is trapped in the bellows to prevent a collapse when the liquid to be metered is.supplied under pressure. The pumping space 28, for the liquid to be metered, has a series of inlet valves 86, each comprising a lightweight plate of substantially triangular shape and the delivery side has a valve of similar shape and also a spring-loaded lift valve 90. A valve 113 permits release of air and vapour. The spring 78 may be replaced by a tension spring within the bellows.

Filed: 1977-04-15
Abstract: The device has a hydraulic cylinder (10), which is controlled by a control valve (9) for opening and closing an inlet, exhaust, fuel injection or starting valve (11). The control valve (9) is in turn controlled by a computer unit (6) which calculates the optimum timing control for the valve (11) on the basis of an electrical signal representing the movement of the pistons or the crankshaft. The hydraulic control valve (9) can be driven by multi-layer piezo- electric actuators (12). As a result the internal combustion engine (1) can be of more compact construction, the mechanical loss can be reduced, the efficiency increased, the direction of rotation of the engine (1) easily changed and the noise emission considerably reduced. <IMAGE>
