Title: Improvements in or relating to pass word locks
IPC: E05B37/02
Filed: 1935-06-11
Abstract: 456,169. Permutation locks. KITTLER, A., 21, Rubesova, and PALOUS, G., 9, Krakovskß, both in Prague. June 11, 1935, No. 16875. Convention date, Feb. 8. [Class 44] A permutation lock comprises a two or more lettered discs 19, 19<1> connected to corresponding sleeves 15, 151 surrounding a central spindle 11, the sleeves terminating in discshaped members 16, 16<1> having each a series of blind slots 17 and a through slot 18 for the passage of a projection 24 on a bolt 10, the sleeves being separable into parts at toothed junctions 53 or separable from the discs 19, 19<1>, for the purpose of changing the combination but only when the door is open. The bolt is moved by a lever 12 on the spindle 11, the lever having a slotted end engaging a pin 13 on the bolt. The projection 24<1> is mounted on a twoarmed lever 24 pivoted on a pin 25<1> on the bolt, a handle 25 enabling the projection 24<1> to be moved out of the plane of the discs 16, 161 when it is required to withdraw the bolt from inside the door. The projection 24<1> is normally biassed by a spring 52 into the plane of the discs. A projection 29 on a lever 28 is movable into the path of the projection 24<1> to prevent its withdrawal by the handle 25. A flange 34 on the bolt normally prevents axial movement of the sleeves 15, 15<1> but when the bolt is in a partially withdrawn position a gap 20, Fig. 3, in the flange permits the passage of a segment of an annular projection 16<a> on the last disc 16. Axial separation of the sleeve parts is then effected by moving a plate 21 having ramps 21<1> which engage behind the discs 16 16<1>, whereupon the discs 19, 19<1> can be reset to a new combination. This can only take place after the door has been opened to give access to the end 21<a> of the plate 21, and when the projection 24<1> is in the slots 18. Whenever the projection 24<1> is in its inoperative position the opposite end 27 of the lever 24 engages the projection 16a and prevents axial movement of the sleeves. A two armed spring 31, 31<1> is mounted on a fixed pivot 32 and is engaged by projections 30 on the bolt which cause the bent end 33 to engage the notches 17 on the discs and scatter the combination as soon as the projection 24<1> has moved clear of the slots 18 into the annular space within the last disc 16. Alternatively this spring may be mounted on the bolt. In a modified mechanism a projection on the last sleeve engages the surface of the bolt to prevent axial movement except when the bolt is moved to bring a slot therein opposite to this projection. Instead of forming the sleeves 15, 15<1> in two parts they may be formed with external teeth engaging internal teeth on the discs 19, 19<1>, the teeth being brought out of engagement when the sleeves are moved by the action of the sliding plate 20.

Filed: 1937-06-21
Abstract: Surfaces are coated with coherent gold films by bringing them into contact with a solution containing, inter alia, an organic gold compound having the empirical formula R2 Au X or R11 Au X (where R and R11 represent respectively a univalent and a divalent hydrocarbon radical which may be substituted and X represents a halogen atom), or an organic gold compound which can be derived from such a compound by reaction with a silver salt.  A typical example of a compound of the formula R2 Au X is diethylmonobromogold; compounds which can be prepared from this by reaction with silver salts are for example diethylmonocyanogold and tetraethylmonosulphatodigold. Numerous suitable compounds of the types described are specified and their preparation from other specified organic gold compounds is referred to; reference is also made in these connections to articles in the Journal of the Chemical Society and the Journal of the American Chemical Society.ALSO:Surfaces are coated with coherent gold films by bringing them into contact with a solution comprising a monohydric alcohol capable of undergoing direct oxidation, e.g. ethanol, methanol, n-propanol, n-butanol, or benzyl alcohol, an alkali metal hydroxide or alcoholate, and an organic gold compound having the empirical formula R2AuX or R11AuX (where R represents a univalent and R11 a divalent hydrocarbon radical which may be substituted and X represents a halogen atom), or an organic gold compound which can be derived from a compound of this formula by reaction with a silver salt.  At least one molecule of the hydroxide or alcoholate is used for each atom of gold in the organic gold compound.  The alcohol may be diluted with an inert miscible liquid such as acetone, tertiary butyl alcohol, or benzene.  A typical example of a compound of the formula R2AuX is diethylmonobromogold; compounds which can be prepared from this by reaction with silver salts are for example diethylmonocyanogold and tetraethylmonosulphatodigold.  Numerous suitable compounds of the types described are specified and their preparation from other specified organic gold compounds is referred to; reference is also made in these connections to articles in the Journal of the Chemical Society and the Journal of the American Chemical Society.  Surfaces which may be coated include glass, silica, textiles such as natural or artificial silk, cotton and wool, paper, mica, vitreous enamel, porcelain, china, synthetic resins, wood, wax, and metals such as copper, nickel, aluminium, zinc, magnesium, stainless steel, brass, and magnalium.  Paraffin wax may be used for protecting portions of the article or the containing vessel where a coating is not desired, as the rate of deposition of the gold on paraffin wax is much less than on other surfaces; any gold deposited on the wax may be subsequently recovered by mechanical or chemical means. After coating, the articles may be washed, e.g. with ethanol or successively with water, ethanol, and ether. Numerous examples are given.

Abstract: 1,182,222. PN junction diodes. MOTOROLA Inc. 11 April, 1968 [9 May, 1967], No. 17499/68. Heading H1K. A variable capacitance PN diode is made by epitaxially growing on a low resistivity substrate a layer the resistivity of which decreases sharply from the substrate outwards, providing an apertured passivating coating on the layer, diffusing impurity through the aperture to form a shallow PN junction in the layer and providing ohmic contacts on the diffused region and substrate respectively. In a preferred device the substrate is of 0À008-0À015 ohm cm. antimony doped silicon orientated 2 degrees off the 111 crystallographic axis towards a 110 axis, and the layer deposited at 1000‹ C. to a thickness of < 8 Á. The layer resistivity is 10 ohm cm. adjacent the substrate and 0À05-0À3 ohm cm. at the surface which may then be coated with intrinsic silicon 4000 Š thick. Diffusion is effected through a 5000 Š silica passivating layer by heating to 1080‹ C. in boron tribromide. Contact is then made to the diffused region by successive vaporizations of chromium, silver and gold followed by form-etching. Finally after reducing the thickness of the substrate by abrasion or acid-etching a back contact of antimony doped gold is applied.
