Title: Improvements in or relating to systems for lubricating and supporting horizontal tables of machine tools
IPC: F16C29/02
Filed: 1944-11-17
Abstract: 618,764. Fluid bearings. CINCINNATI MILLING MACHINE CO. Nov. 17, 1944, No. 22869. Convention date, March 10. [Class 12 (i)] A horizontally moving table as of a machine tool has bearing portions which are located between vertically spaced parallel fixed bearing surfaces and are supported by lubricating liquid introduced under pressure between the bearing portions of the table and the fixed bearing surfaces, the total thrust being varied as the clearances between the bearing surfaces alter. As shown in the transverse sectional view, Fig. 3, the table 11 of a precision grinding machine is supported on a bed 10 by table bearing-portions 20, 19 which slide on the ways 18, 17 and are located below overhanging gib portions 22, 21. Oil supplied under pressure by a pump 100 passes by ducts 26, 25 to the bearing surfaces and passes thence by the small clearances formed below appropriate lands to intermediate pressure spaces and to drainage. Fig. 2 is an enlarged view showing the arrangement for the table bearing portion 20. Oil at pump pressure is supplied to the bottom recess 2 (by duct 26, Fig. 3) and passes at the same pressure to side recesses 7 by internal ducts 32, 33, Fig. 2. The faces of the table bearing portion 20 are provided with the intermediate-pressure spaces 4, 9, b, d, Fig. 2, which intercommunicate by internal ducts, Figs. 8, 9; the oil passes by the throttling clearances 3, 8 to the intermediate pressure spaces 4, 9 so setting up an intermediate pressure in the spaces 4, 9, b, d with the oil draining from these spaces 4, 9, b, d through the throttling clearances 5, 10, a, c to the drains 28, 27, 29, 28. The resistances of the throttling clearances are designed by appropriate dimensioning of the widths and lengths of the lands so that the resultant total thrust balances the weight of the table. If the table is displaced downwardly, upwardly, or sidewise, the clearances alter and cause a compensating thrust to arise. The pressure oil may equally well be introduced at the upper face of the table bearing-portion, Fig. 11 (not shown).

Title: Process and apparatus for the continuous fermentation and maturing of beer
Inventor: WOLTER HANS CARL
IPC: C12C11/00
Filed: 1965-05-31
Abstract: In a continuous process for the production of beer, air or oxygen enriched or saturated wort is caused to flow through a propagation vessel, the yeast race or races being added to the wort prior to entry into the vessel or added directly into the vessel, the wort is retained at a fixed temperature and for a fixed time in the vessel according to the race or races used and the required degree of fermentation, the yeast-containing liquid, on leaving the vessel (or vessels), is passed through a fermentation vessel in which the pressure in the liquid increases in accordance with its carbon dioxide content, the fermented liquid leaves the fermentation vessel as the alcoholic content is reached and is partly freed from yeast at the final pressure prevailing in the fermentation vessel, thereafter the fermented liquid is matured by flowing through maturing apparatus consisting of one or more vessels and the pressure within the maturing apparatus is lowered in one or more steps to reach the carbon dioxide content desired of the finished beer.  The propagation is carried out without any further aeration of the aerated wort, the fermentation vessel has a considerable height in relation to the width, which height is governed by the static pressure for the carbon dioxide content of the emerging non-matured beer and by the time the liquid is to remain in the fermentation vessel, and the fermentation vessel may have built-in components for preventing the mixing of the different parts of the fermenting liquids in the successive fermentation phases. Vessels forming the maturing apparatus may be arranged one above another such that over-pressure of 1.2 atm. for the non-matured beer is reduced by about 0.2 atm. each time, down to 0.35 atm. overpressure in the final maturing vessel.  The liquid is conveyed downwardly in the propagation and fermenting vessels, and upwardly in the maturing vessels.  The separated yeast is returned either to the propagation vessel or to the fermentation vessel. The yeast concentration remaining in the fermented liquid is selected in such a way as to ensure that the biological decomposition of flavour-producing material typical of maturing beer will take place under the operating conditions.

Title: Rotary plug valves
IPC: F16K5/16
Filed: 1935-08-22
Abstract: 461,653. Rotary plug valves. CRANE CO. Aug. 22, 1935, No. 23610. Convention date, Feb. 27. [Class 135] A rotary plug valve which is unseated before being turned to the open position . and re-seated after being turned to the closed position comprises a pawl carrier 18 non- rotatably mounted on a threaded stem 8 extending from the plug 5, an enclosure 16 within which the pawl carrier and an actuating nut 21 surmounting the pawl carrier are supported, and a control track or surface 26<x> which causes a pawl 19 pivoted at 18<b> on the pawl carrier to remain in engagement with a notch or groove 21<a> in the nut for rotating the plug before or after its axial movement. The pawl 19 carries a roller 24 near its nose 19<a>. The carrier 18 is connected to the plug stem 8 by means of an hexagonal or other polygonal aperture 18<x>, Fig. 3, and bears on a raised surface 16b in the enclosure or casing 16. A handle 32 and a pointer 31 are non-rotatably connected to the actuating nut 21, a flange 21<c> on which has a lug 21d adjacent the notch 21<a>. The casing 16 which is rigidly connected to the casing 1 by yoke members 20 has a cover 27 attached thereto by equi-angularly spaced bolts 28. Fig. 9 shows the position of the mechanism when the valve is closed but not seated. In this position, the shoulder 18<c> on the carrier abuts the end 26b of a rib 26 depending from the cover 27. Clockwise rotation of the nut 21 causes the nose 19a of the pawl to ride out of the notch 21a and its roller 24 to engage a recess 27d in the cover so that the stem 8 is locked against rotation and the nut forces the plug to its seat formed by upstanding rims 4 around the inlet and outlet passages. Counter-clockwise rotation of the nut first unseats the plug, and when the lug 21d engages the shoulder 18<c>, the nut entrains the carrier and the roller is forced from the recess 27d so that the nose 19<a> again engages the notch 21<a>. The nut 21 and spindle. 8 thus move together until both are stopped in the valve-open position by the shoulder 18d meeting the end 26<a> of the rib 26. The hexagonal aperture in the carrier 18 and the equi-angularly arranged bolts enable the carrier 18 and the cover 27 to be adjusted with respect to the spindle 8 and casing 16 respectively to vary the lift given to the plug. Lubricant may be supplied to the nut and spindle threads by a passage in the nut having a threaded closure plug. In the modified form, Fig. 17, the roller 24 is dispensed with, the pawl having a lug 24<a> which slips over the stop 26<a>, when the valve-closed position is reached so that the nose 19<a> can then ride out of the notch 21<a>. The rotation of the carrier in this case is limited by an arm 18f engaging stops 26<c>, 26d.
