Title: Improvements relating to the alcoholic fermentation of sugarcontaining liquids
IPC: C12P7/06
Filed: 1932-05-25
Abstract: In the alcoholic fermentation of sugar-containing solutions, the consumption of sugar for the proliferation of the yeast is suppressed by maintaining constant the specific cellular saturation of the yeast after this saturation has once for all been attained, by allowing the fermentation to be continued to the end, removing all the yeast that is present in the liquid, and using this yeast again for the fermentation of a fresh volume of liquor such that the total resultant volume is equal to the first. The fermentative activity of the yeast is increased or prolonged by addition of any suitable nutrient agent or by a preliminary de-aeration of the liquor to be fermented.

Filed: 1975-04-11
Abstract: 1463939 Electric incandescent lamps PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 11 April 1975 [16 April 1974] 14977/75 Heading H1F [Also in Division G2] An electric incandescent lamp includes a composite filter which is transparent to visible light and reflects infra-red radiation, the filter consisting of an interference filter and a metal oxide filter doped to provide such a concentration of free electrons that the plasma wavelength is less than 1À4 Ám., the metal oxide filter being the more remote from the lamp filament. The metal oxide filter may comprise a layer of indium oxide doped with at least 7 atom per cent tin to provide a free electron density of at least 10<SP>21</SP> per cubic centimetre. The interference filter may comprise alternate layers of comparatively low refractive index material, e.g. Na 3 AlF 6 , MgF 2  and SiO 2  and comparatively high refractive index material, e.g. ZnSe, ZnS and TiO 2 . Two stacks comprising different pairs of layers may be used. Where the two filters are not spaced apart an adaptation layer of MgF 2  may be located between them. As shown the composite filter 12 is formed on the inside of outer wall 11 of a double walled elliptical crosssectioned tungsten halogen lamp. The two series or parallel connected filaments are located along the ellipse foci, and reflectors 19 are provided at each end of the inner envelope. Other possibilities for location of the two filter components are, in the case of a single walled envelope, both inside, both outside or one inside and one outside. In the ease of a double walled envelope both may be located on the outer wall, both on the inner wall or one on each. The filament must have a shape adapted to that of the composite filter and lie at its optical centre whereby reflected radiation strikes the filament.

A method of making a set of bars for forging into the blades of gas turbines comprises casting enough bars to form a set, putting each bar into an individual mould and remelting under vacuum, the metal cooling in each mould to give a final bar, and reheating these final bars and hot-swaging to eliminate any cavities. The bars are first cast in cylindrical moulds, shotblasted to remove surface oxides and remelted in moulds of fused alumina or zircon. The bars are vacuum purged, the temperature is lowered to near the freezing point of the metal and the bars are then rapidly cooled to give a small grain size. The final operations are hot-swaging, centre-less grinding and cropping the bar-ends.

Abstract: 918,660. Automatic gramophones. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 14, 1959 [May 14, 1958], No. 15472/58. Class 40 (2). In an automatic gramophone a tap-tap lever 5 is frictionally coupled to a pivotally mounted actuating arm 8 on a movable post 6, and an operating pin 16 is coupled by a driving element 17 to the pick-up arm shaft 4 and movable to engage and swing the actuating arm such that, when the tap-tap lever is moved longitudinally after the run-off groove has initiated such movement, the actuating arm is moved in the same direction as the driving element 17 normally moves during record playing, whereby reaction on the pick-up arm is reduced. During the early stages of the playing of a record the operating pin 16 moves along a slot 7 in the base-plate 2 in the direction of the arrow shown in Fig. 1. At a later stage the pin 16 engages a cam 12 on the actuating arm 8 and moves it and the tap-tap lever about post 6 towards a striking lug 20 on the turntable spindle. When the stylus passes into the runoff groove, the end of the tap-tap lever intercepts lug 20 and is moved longitudinally so that post 6 passes along an arcuate section 7a of slot 7 to break a switch or initiate an automatic cycle, and at the same time moves the cam surface 12 away from the operating pin 16. Outward movement of the pick-up arm later causes pin 16 to engage the left-hand ends, as viewed in the Figures, of slots 13, 14a, respectively, in arm 8 and lever 5 to restore the parts to their initial positions.
