Abstract: 1,088,309. Recording and playback. MINNESOTA MINING & MANUFACTJRING CO. Feb. 25, 1965 [March 13, 1964], No. 8203/65. Heading GSR. [Also in Division H3] In a system for recording information having a wide amplitude range and for reproducing the information without distortion, the information is recorded on two separate tracks at two levels, the levels being such that they are equal at low frequencies, while one increases relative to the other as the signal frequency increases. In playing back the recorded information, the output from the higher level track 22, which passes via a de-emphasis unit 28 to a switch 26, is normally used except where its amplitude is so great that distortion occurs. When the amplitude reaches such a level, a trigger 31 is operated and this actuates the switching arrangement 26 to disconnect the output from the head 22 normally used and apply the signal from the head 23 to the output. Detailed conventional circuitry for the pre-emphasis unit in the recording arrangement and for the trigger circuit 31 is described, and the circuit for the switch 26 is also explained (see Division H3).

Title: Improvements in or relating to the production of beer
Inventor: CURTIS NORMAN SIDNEY
IPC: C12C11/00
Filed: 1964-02-27
Abstract: The foam stability of beer is improved by carrying out the fermentation of brewers' wort under conditions such as to maintain the foam head formed during fermentation in a wet condition and substantially to prevent a barm head from forming. The maintenance of the wet condition of the foam head is achieved by continuously circulating the fermenting wort through a sparge arm placed over the contents of a vessel containing the wort, whereby the foam head is sprayed with liquid.  The formation of the barm head is substantially prevented either by using a variety of yeast which does not form a barm or skimming head or when conventional top yeast is used, by removing the yeast from the fermented wort whilst the foam head is still in a wet condition.  Preferably the maintenance of wet condition in the foam head is limited to about the first 30 hours of fermentation as this enables the pH and flavour to be controlled without losing the benefits of foam stability.  The sparge arm may be self-propelling or independently driven.  An example is directed to the fermentation of 870 gallons of brewers' wort in a fermentation vessel; during the first 30 hours of fermentation, the fermenting wort was circulated continuously through a sparge arm at a rate of 5.1 gals. per square foot area of the vessel per hour.

Title: Method and means for controlling foaming of casting compositions during casting
IPC: B29C39/00
Filed: 1963-03-01
Abstract: 1,021,273. Vibratory agitators; dissipating foam and entrained air in liquids. R. M. BERGSTEIN, and F. D. BERGSTEIN. March 1, 1963 [March 1, 1962], No. 8305/63. Headings B1C and B1M. [Also in Division B5] Foam and entrained air bubbles in a fluid composition recovered from a casting operation may be dissipated by collecting the recovered casting composition and subjecting it to vibration at a frequency of 2000-5000 vibrations per minute. In a specific embodiment, Fig. 2, a rotating casting drum 1 has a layer of casting composition held in vessel 5, applied to it by drum 4 before passing through heater 9. The excess of casting material on the drum is doctored from the casting surface e.g. using an air knife 6 and flows down sheet 7a to collecting vessel 7. Sheet 7a and vessel 7 are both vibrated by means of vibrator 14, thus removing the foam and entrained air, and the composition is withdrawn from the bottom of the vessel 7. The recovered composition is passed via valve 16, pump 18 to storage tank 17 whence it is recirculated by pump 20, cooler 21 which acts in conjunction with temperature control 28, filter 22 and vessel 23 to tank 5. Vessel 23 contains a viscometer 24 which regulates the amount of water or solvent added to collecting tank 7 through conduit 27, thus governing the viscosity of the coating composition. If a laminated cast layer is required a backing web e.g. of paper or boxboard is added using roller 11 and the finished product is removed over roller 12. An aqueous slurry containing clay, calcium carbonate or titanium dioxide together with a binder comprising a vinyl acetate or acrylate emulsion may be used as a casting composition. A polyethylene emulsion, and a vinylidene chloride or styrene copolymer latex is also mentioned.

Abstract: 882,125. Rolling screw-threads. MALMEDIE & CO. MASCHINENFABRIK G.m.b.H. March 11, 1959 [March 14, 1958], No. 8448/59. Class 83 (4). In a thread-rolling machine having a pair of flat rolling dies 34, 36, one die 36 being stationary while the other reciprocates, a feeding mechanism is provided which comprises a first channel 58 laterally opening into a second channel 150 pushing means including a reciprocating pushrod 98 in the second channel 150 for feeding a single blank to the dies, the push-rod 98 closing the channel 58 when feeding, blank-moving means for moving a blank into the channel 150 and lock means including a movable lock member which may be operatively disposed in the channel 58 so that only one blank may be moved at a time into the channel 150 and drive means for the push-rod 98 and the lock member adapted to unlock the lock member when the push-rod 98 feeds a blank and to lock it again on retraction of the push-rod 98, the drive being synchronized with the main drive of the reciprocating die so that the blank pushed by the pushrod enters the gap when the dies are about to start a rolling cycle. The push-rod 98 is reciprocated by a slide 92 guided in a housing 94 and actuated in the feed direction by a spring 104, the slide being retracted against the spring pressure by a cam-operated lever 110 engaging a shoulder 136. If desired the feed may be stopped by holding the slide 92 in the retracted position by engaging a projecting shoulder of a spring- loaded plug 158 with a shoulder 176 on the slide. Bolt blanks 62 are fed from a sorting and aligning mechanism of a rotatably mounted blank container into the channel 58 comprising parallel bars 60, 61 adjustable for their distance apart. On the feed stroke of the push-rod 98 one blank is fed along the channel 150 the following blanks being retained in the channel 58 by the side face of the push-rod. A wedge-shaped locking member 138 attached to a spring-loaded pivoted arm 140 is rendered inoperative during the feed stroke by pressure of the slide 92 on a pin 146 also carried on the arm 140. As the push-rod 98 retracts the pin 146 is released and the wedge member 138 enters the channel 58 laterally to push one blank into the channel 150 ready for feeding while retaining the subsequent blanks in the channel 58. One blank is thus fed to the dies 34, 36 every time the die 34 reaches the position corresponding to the beginning of a rolling cycle, the blank being subsequently threaded on the forward stroke of the die 34 which is mounted on a slide 30 reciprocated by a crank 26 attached to a flywheel 18 on the main drive shaft. The die 36 may be laterally adjusted by screws 56.
