Abstract: 698,599. Door locks. GENERAL MOTORS CORPORATION. Feb. 22, 1952 [March 21, 1951], No. 4677/52. Class 44 In a motor vehicle door lock having a latch bolt and two separate bolt-actuating mechanisms each for connection to a respective door handle, the first mechanism including a member displaceable at will to render the lock operable or inoperable by the first mechanism handle, the second mechanism includes two juxtaposed coupling members, the one member being connected to the bolt and the other to the second mechanism handle and a connector displaceable either to positively inter-engage the coupling members for operation of the bolt by the second handle or to disengage them to render the handle inoperative. In the arrangement shown in which the lock elements are mounted upon a plate 1 and in which a pivoted bolt engages a conventional striker plate, a tailportion 9 of the bolt is engaged by fingers 27 of a pivotally mounted operating lever 18 which is spring- biased in a counter-clockwise direction and which constitutes one member of a coupling. The tail portion 9 is also engageable by a reciprocable push bar 35 which is pivoted about a pivot 32 common to the bar 35 and a channel guide member 30. The upper end of bar 35 is pivotally connected to the guide member 30 and to a spring loaded tumbler 33 which latter is movable by a trigger 47 rotatable from the outside of the door by means of a keyoperated combined torque rod and plunger 50. A control plate 39, pivoted about a pivot 40 to the plate 1, is pivotally connected to an arm 31 of the channel member 30 and is rotatable by means of a button 80 on the inside .of the door through links 43, 44 and lever 42, to move the bar 35 into or out of engagement with the bolt tail 9. A coupling lever 61 pivoted about the pivot point of lever 18 constitutes the other member of a coupling and is connected through a link 28 with an inside handle 8. The lower ends of levers 18 and 61 are formed with slots 62 and 63 respectively by which the levers may be coupled by means of one end of a link 64, the other end of which engages an L-shaped slot in plate 39. The link 64 is biased upwardly by a spring 70. The arrangement is such that operation of the button 80 from the position shown in Fig. 1 is effective to render both inside and outside handles effective or ineffective simultaneously without jamming the lock.

Title: Improvements relating to the manufacture of yeast
IPC: C12N1/18
Filed: 1921-02-17
Abstract: 180,043. Gilmour, R. Feb. 17, 1921. Yeast.-A light-coloured yeast is produced from molasses by subjecting the molasses to a treatment, before fermentation, with charcoal or decolorizing-carbon in one of two ways. (1) The molasses solution is acidified and boiled with bone charcoal &c. and 5-20 per cent of albumenoid-containing material such as malt combings, grain, bran, wheat or maize germs, dried yeast, or other by-product of the flour milling, brewing, or distilling industries. Yeast foods such as phosphates and salts of ammonium, potassium, calcium or magnesium are then added, and the acidity of the solution is adjusted to bring about maximum precipitation of albuminoids, which occurs in general near the neutral point. Filtration may be performed both before and after, or only after, adding the yeast foods. (2) The molasses is boiled with a quantity of bone charcoal and sulphuric acid, sufficient to provide the phosphoric acid requirements of the yeast. The solution is then neutralized, filtered, and treated with yeast foods, or boiled with albuminoid material and then treated with yeast foods, neutralized, and filtered. The molasses solution which has been subjected to either of these treatments may be treated with malt at about 60‹ C., and filtered. The liquid is then diluted, seeded with yeast at 25‹-30‹ C., and aerated during fermentation for 15-20 hours. The solution is kept nearly neutral by adding ammonia or other alkali or alkaline carbonate, until towards the end of fermentation, when the acidity is raised somewhat by the addition of sulphuric or lactic acid. The fermentation is allowed to continue for 2-3 hours, after which the yeast is separated and pressed in the usual manner. The Provisional Specification also describes the treatment of molasses with another form of charcoal together with calcium phosphate and sulphuric acid, or with carbon and free phosphoric acid.
