IPC: B23Q11/00
Filed: 1959-01-21
Abstract: 913,242. Automatic lathes. HAHN, E., [trading as INDEX-WERKE KOMM.-GES. HAHN & TESSKY]. Jan. 21, 1959 [March 28, 1958], No. 2290/59. Class 83 (3). Control mechanism for automatic lathes utilizes the reciprocating movement of a toolslide e.g. a turret-slide to move a rotatable control element carrying cams &c., in one direction only, a " lost-motion " coupling operating to move the control element on to a predetermined angular position at the end of each tool-slide reciprocation. The turret slide 11, Fig. 1, is provided with a rack 15, Fig. 3, which engages a gear 18 which is thus rotated in opposite directions when the slide carries out a forward and return movement. The wheel 18 is secured to a shaft 22 which is geared to another parallel shaft 32 by gears 20, 33. These gears drive through uni-directional clutches 24, 35, and pinions 26, 36, respectively, a large internallytoothed drum 30. The cycle control plate or switch drum 38 is secured to the drum 30 and operates control elements for the various operating parts of the automatic lathe. In order to bring the drum 30 into a predetermined position after each complete reciprocation of the turret slide a lost-motion clutch 50 is employed. This is driven from a " onerevolution " shaft 42 at the desired time so that the inner clutch member 58, Fig. 5, does a full revolution. A spring-pressed pawl 57 on this member picks up a lip 55 on the outer member after some lost-motion and brings the outer member to the desired " zero " position. The outer clutch member 52 is in the form of a pinion which is in constant mesh with the internal teeth of drum 30. The Specification refers to, but does not describe in detail, the use of other control plates including perforated cards scanned by photo-electric cells, magnetic cards and cards with raised bosses.

Title: The Production of Traditional Beer (Southern Africa)
Inventor: CLAYTON DAVID HENRY
IPC: C12C5/00
Filed: 1968-01-18
Abstract: 1,184,032. African beer. A.B.M. INDUSTRIAL PRODUCTS Ltd. Jan, 2, 1969 [Jan.18, 1968], No.2752/68. Heading C6E. A process for the production of Traditional beer (Southern Africa) in which some of the starch present in a cereal mash which comprises raw sorghum corn (or other appropriate cereal material) is converted into fermentable sugar, involves heating the mash to gelatinize the starch, cooling the mash to a temperature between 50‹ and 70‹C., adding to this mash a mixture of the commercial enzymes amyloglucosidase and α- amylase, allowing the controlled hydrolysis of the starch, present in the sorghum corn, to fermentable sugar to take place for a predetermined period of time so that a required quantity of fermentable sugar is produced while a required quantity of suspended starchy solids remains, cooling the mash to a temperature suitable for alcoholic fermentation and subjecting the mash to alcoholic fermentation, and the mash is soured by incorporating at an appropriate stage a sour liquor produced by the action of lactobacilli viz prior to gelatinization, after cooling of the mash but prior to the enzymatic hydrolysis, or after the enzymatic hydrolysis. The mash may be supplemented with maize grits. The enzymatic hydrolysis is carried out at a temperature of 60‹-62‹C. usually for 2 to 4 hours until the dextrose equivalent of the mash is not less than 30% and preferably between 45 and 50% of the total carbohydrate solids. A pre-gelatinized enzyme-converted starchy material (whether soured or not) may be carefully spray-dried prior to the completion of the enzymic action to give a pale buff, slightly hydroscopic powder. The enzymatic hydrolysis will be resumed when the spray dried product is redispersed in water. The water supplied to the processes should have a calcium hardness equivalent to not less than 100 p. p. m. by weight of calcium carbonate. The sour liquor may be produced by mashing sorghum corn malt in the presence of lactobacilli as by the action of the lactobacilli on a mash produced by the action of the commercial enzymes amyloglucosidase and α- amylase on a gelatinized cereal. This mash may have been divided from the prepared main mash.

Filed: 1972-01-24
Abstract: 1366981 Photo-electric lens centring WESTERN ELECTRIC CO Inc 24 Jan 1972 [25 Jan 1971] 3192/72 Heading H4D A method and apparatus of centring an optical element having two surfaces so that the optical axis is aligned along a predetermined axis, including directing electromagnetic radiation at the element, receiving reflected radiation, providing a signal representing the decentring of the element, and adjusting the position of one or each centre of curvature of said surfaces while the other centre of curvature remains stationary to correct for the decentring. Laser 115 in collimator 21 provides a beam of light whose size is adjusted by lenses 117 and the position of the collimator is adjusted by motor 161 to match the wavefronts in the beam to the curvature of the lens. The beam is reflected by prisms 125 on to the top surface of lens 135 mounted in manipulator 31. Reflected light is received by a photodetector 151 comprising four quadrant detectors or a silvered pyramid. The relative amplitudes of the signals received by the four detectors as the lens 135 is rotated about the axis of support rod 311 indicates the decentring of the lens which is determined by digital computer 11. The computer then controls manipulator 31 to move the lens by small amounts towards its correct position in the two directions perpendicular to the axis of rod 311. It then computes a value for movement along the axis to make the total movement a rotation about the centre of curvature of the lower surface. The decentring is then determined once more and the process is repeated until the centre of curvature of the upper surface lies on the axis of rod 311. The position of the lens along rod 311 is then adjusted to correctly position the centre of curvature, utilizing the output of interferometer 165. The collimator is then adjusted once more to match the beam to the lower surface and the centre of curvature thereof is correctly positioned. A compound lens may be manufactured by centring several lenses correctly spacing them using the interferometer and cementing them together. The manipulator 31 is described in detail (Fig. 3, not shown) and comprises two plates moving on roller bearings to provide movement perpendicular to the rod 311 axis and a further plate with three adjustable legs which uniquely determines the position of the lens 135 which is mounted thereon and also provides for tilting the lens and movement along the rod axis.
