Abstract: 1,003,023. Semi-conductor devices. SIEMENS & HALSKE. Sept. 19, 1963 [Sept. 21, 1962], No. 36872/63. Drawings to Specification. Heading H1K. A semi-conductor material is highly doped with two or more elements which produce the same type of conductivity, the total solubility of the doping elements in the semi-conductor material being greater than that of any one alone. Each doping element forms a eutectic mixture with the semi-conductor material, and the mean of the atomic radii of the doping elements is approximately equal to the atomic radius of the semi-conductor material (if this is an element) or of the element which is replaced in the semi-conductor crystal lattice (if the semi-conductor material is a compound). Examples given of suitable combinations of doping elements in silicon or germanium include phosphorus with arsenic, aluminium with gallium, boron and indium with either aluminium or gallium, lithium with either phosphorus or arsenic, and copper or zinc with either boron or aluminium or gallium. At least two elements from Group II or from Group VI may be incorporated as doping elements in an A III B V  compound. Embodiments described include a tunnel diode and the emitter zone of a transistor.

Title: Process and apparatus for the regulation of the supply of nutritive solution and air during the growth of yeast in mashes for baker's, food and fodder yeast
IPC: B01J4/00
Filed: 1959-10-30
Abstract: 882,476. Regulating yeast. PATENTAUSWERTUNG VOGELBUSCH G.m.b.H. Oct. 30, 1959 [Nov. 14, 1958], No. 36979/59. Class 14 (2). In the production of yeast in a mash, the regulation of the respective rates of supply to the mash of oxygen and nutritive material is derived from the instantaneous alcohol content of the exhaust gases, by collecting the gases in a known amount or at a known rate and measuring the alcohol content, e.g. with a refractometer or colourimetrically; the change in refraction or discoloration may be measured continually and converted into an electric signal which is used for automatically adjusting the rates of supply either in an on-and-off manner or by proportional adjustments. A portion of the alcohol-containing exhaust gases escaping from a vat a through a conduit b is drawn by a precision pump c 1  into a heated reaction vessel e containing a sulphuric acid solution of potassium bichromate of a determined concentration, supplied by a pump c 2 ; the discoloration produced is continuously measured in a colourimeter g and the signal derived is, after suitable amplification used for regulation of valves controlling the supplies of nutrient solution and air. The pumps c 1 , c 2  may be replaced by a syphon or aspirator, and a drip feed, respectively. German Specification 739,021 is referred to.

Title: Bakery product depanning apparatus
IPC: B65G17/46
Filed: 1972-08-08
Abstract: 1361916 Transferring articles between endless conveyers; suction-holding appliances BAKER PERKINS Inc 8 Aug 1972 [13 Dec 1971] 37009/72 Headings B8A and B8H [Also in Division A2] In suction depanning apparatus in which loaves &c. B are removed from pans 12 on a conveyer 10 and transferred to a conveyer 9 by resilient cups 50 carried by slats 42 on a transfer conveyer comprising chains 40, means are provided for closing, under certain conditions, the apertures by which the cups communicate with a suction box defined by end walls 27, side walls 26, and a top wall 28, thereby enabling use of a relatively low power suction fan 30, which is connected to the box by a duct 32. On starting up, before the attainment of sufficient working suction, a pressure switch 71 in the box causes a fluid-pressure operated cylinder 68 to position a shoe 64, which is pivotally mounted at 67, against the inner surfaces of the slats 42 so that the suction passages to a number of the cups are closed. This allows the suction to build up to a value such that valve members 60 in those cups that are below the suction box but not affected by the shoe 64 are lifted against gravity by inflowing air to seal the suction passages 54. The suction is thereby enabled to build up to a higher value at which the switch 71 operates to cause the cylinder 68 to raise the shoe 64 to condition the apparatus for transfer of loaves from the pans 12 to the conveyer 9. If, during operation, any cup does not make contact with a loaf, its valve member 60 is closed by inflow of air. The valve members 60, which are retained and guided by clips 58, are bevelled at 60a to decrease the likelihood of their closure by deformation of the cups. A modified form of clip has a portion which projects upwardly into a central hole in the valve member.

[Also in Divisions C7 and Fl] The continuous supply of liquid through pipe 3 into an evaporation receptacle 2 enclosed within vacuum chamber 1 is controlled by an external feed chamber 24 which is at a lower level than receptacle 2 and is connected as shown to a liquid reservoir 6, a pump 8 which circulates the liquid through chamber 24 and reservoir 6, and an adjustable sleeve 32 which maintains a constant level of liquid in chamber 24. The liquid flows up tubes 15 and 3 onto receptacle 2 because of the difference of pressure between chambers 1 and 24. Chamber 24 may be open to the atmosphere, or it may be enclosed and maintained at a pressure intermediate atmospheric pressure and the pressure in chamber 1. Means (not shown) are provided for heating receptacle 2 in order to vaporize liquid therein. The vapour may be condensed on a substrate which is continuously moved through chamber 1. When the liquid to be evaporated is molten metal (see Division C7), reservoir 6 is surrounded by a furnace 14, and other parts of the apparatus are thermally-insulated.

Abstract: 854,695. Photographic colour processes. GEVAERT PHOTO-PRODUCTEN N. V. Nov. 26, 1956 [Nov. 26, 1955], No. 37027/58. Divided out of 854,693. Class 98(2) In preparing a colour component image corrected by an integral mask formed by the silver salt diffusion process as in Specification 634,169, development of the component image is effected after development of the maskforming silver salt layer and diffusion into the receiving layer. This may be accomplished by adding an inhibitor to the emulsion for the component image or to an adjacent layer, or by means of a protective layer coated over the emulsion, effecting development and diffusion in the mask-forming layers with a hydroquinone developer containing hypo, and subsequently developing the component image in a metol/hydroquinone developer. Alternatively, an active developer like metol or "Phenidone" (Registered Trade Mark) may be added to the silver salt emulsion for mask-forming or to an adjacent layer, the exposed material being processed by developing with a developer of little activity or long induction time (e.g. hydroquinone) in the presence of hypo to form the mask, and subsequently developing the component image in a metol/hydroquinone developer. The mask-forming layers may be coated on the opposite side of the support to the component image layer as in Specification 854,693. Specification 854,694 also is referred to.

Title: Improved polyglycidyl ether condensation polymers
Inventor: TANNER EDWARD BUTLER
IPC: C08G59/44
Filed: 1964-09-22
Abstract: Condensation polymers are obtained by condensing a glycidyl polyether of a dihydric phenol with a product containing both carboxyl and amide groups; the latter is obtained by condensing ammonia or an organic compound containing primary amine groups with an excess of a polycarboxylic acid or anhydride of such an acid.  Half-amides obtained by reacting equimolar proportions of ammonia or amine with a dibasic acid are particularly suitable. The dibasic acid may be a dimerized fatty acid.  Coating compositions may be produced by dissolving or dispersing the condensation polymers in a solvent and neutralizing the polymer by adding alkali (e.g. NaOH) either to the polymer or polymer-solvent mixture.  The compositions are suitable for coating (e.g. of metals) by eletrode position.
