Abstract: 1,255,483. Coated metal objects. B.P. CHEMICALS Ltd. 22 Oct., 1969 [18 Nov., 1968], No. 54590/68. Heading B2E. [Also in Division C3] Metal objects may be coated with a polyamide P by fluidized bed dip coating, electrostatic deposition, or flame-spraying. Polyamide. P comprises residues derived from: dicarboxylic acid(s) A containing #6 C-atoms; an acyclic polymethylene diamine B having 7-12 C-atoms in the chain, the chain bearing 1-3 alkyl substituents; and a cyclic diamine C such that its 2-dimensional structural formula does not possess an axis of symmetry passing through the amine groups. A may be one or more of e.g. adipic, sebacic, azelaic, or dodecanedioic acid, or an alkyl-substituted derivative thereof; tere- or isophthalic acid or hydrogenation products thereof; or phenylenediacetic acid. B may be 5-methylnonane diamine. C may be 3-aminomethyl-3,5,5-trimethylcyclohexylamine or m-xylylene diamine. Preferably C forms 10-40% moles of. the total diamine. Also present in P may be up to 20% moles of the total amine component of residues of, e.g. H 2 N-(CH 2 ) 6 -NH 2 , H 2 N- (CH 2 ) 12 -NH 2 , caprolactam, oenantholactam, or H 2 N-(CH 2 ) n -COOH where n is 5, 6, 10; or 11. P may be prepared by condensing, e.g. at 230-300‹C in the absence of free O 2 , the amines and the acid(s) A derivatives thereof, e.g. diesters or acid chlorides; e.g. by melt-polycondensation methods, e.g. simple diacid/ diamine condensation or condensation of the "nylon salt". A and the amines may be used in equimolar quantities or # 5% wt. excess of the amines may be used. The process may be performed in a twin-screw reactor. Also present may be a colour stabilizer, e.g. 0.001- 2.5% of ammonium hypophosphite, triphenylphosphite, diethyl hexylphosphite, or tris(nonylphenyl) phosphite. Acetic acid or monoamines may be added to control the M.W. of P. P preferably has viscosity >0.7. The Vicat softening point may be, e.g. 132.4‹C or 143‹C.

Abstract: 1378826 Regulating timepieces electrically DIXI SA 28 Nov 1972 [10 Dec 1971] 54824/72 Heading G3T In order to synchronize a mechanical oscillator with a standard frequency, the latter is divided to give periodic pulses which are fed to an electromechanical transducer to displace a member to a position where it may engage a part of the mechanical oscillator. As shown, pulses T derived from a crystal oscillator 1 via a frequency divider 2 are fed to a solenoid coil 5 to displace a pin 7. In the displaced position the pin engages the hairspring 8 of a balance 9 driven by the mainspring of a manually or automatically wound movement. The balance is adjusted to run slow and engagement by the pin 7 at the point g, Fig. 4, causes premature reversal of the balance to speed it up. In an alternative embodiment, the balance is adjusted to run at substantially the correct frequency and the pin 7, in its displaced position, engages a projection (12), Figs. 5-8 (not shown) on the rim of the balance only if the latter is running fast or slow, and correspondingly slows or speeds up the balance.

Title: Improvements in portable lighting apparatus
IPC: F21L23/00
Filed: 1966-12-21
Abstract: 1,129,930. Miners' lamps. KOEHLER MFG. CO. 21 Dec., 1966 [1 March, 1966], No. 57140/66. Heading F4R. A miner's cap lamp has locking means for the lens-retaining bezel which can only be released by attaching the lamp to a suitable fitting on a battery charging rack. In the preferred embodiment the headpiece 2 (Figs. 12, 13) to which the bezel 5 is screwed is formed with an extension 20 provided with a rectangular recess R in the base of which is formed a ramp 29. Secured to the ramp by a screw 29a is a cover-plate assembly 24, 26, 28 which forms, in conjunction with the ramp and the edges 20a of the extension 20, a pair of slideways 31, 33 to receive the edges 56, 58 (Fig. 4) of the fitting C. The ramp 29 has a cavity containing a slide S which is urged towards the bezel by a spring 32 and has a tip T adapted to engage in one of a series of notches N spaced around the rim of the bezel. A pivoted latch 44 engages a locking slot 42 in the slide, the shape of the slot being such that if the side 42a bears against the latch the slide can move forward under the action of the spring 32 and the latch can pivot, but if the side 42b bears against the latch the latter jams and movement is impossible. When the headpiece is attached to the fitting C so that the edge 58 enters the slideway 33, as shown in Fig. 12, the edge 58 abuts a cam surface 46 on the latch and rotates the latch to withdraw the slide so that the bezel is free to be removed or tightened as required. When the headpiece is removed from the fitting the slide advances and the tip T can be engaged with a notch N by slight rotation of the bezel. If, however, the headpiece is attached to the fitting in the reverse direction so that the edge 56 enters the slideway 33 a bevelled portion 56a of the edge approaches the cam surface 46 (Fig. 14, not shown) and the slide is not withdrawn. In this way the battery can be charged without unlocking the bezel. The charging circuit is completed through the screw 29a, which connects with a contact 60 on the fitting, and a contact 73 which connects with one of the edges 56, 58. Spring clips and trapping spaces are provided in the ramp 29 (Fig. 3, not shown) to prevent the insertion of tools. In a modification (Fig. 18, not shown) the slide is installed at an angle to the axis of the headpiece and the tip has a bevelled surface to engage the notches in the bezel.

[Also in Division C2] Photographic colour images are formed from a material having at least one silver halide emulsion layer and containing in said emulsion layer or a layer adjacent thereto a uniformly dispersed non- wandering organic compound which forms a coloured complex with free transition metal ions by (1) forming a silver halide image in said emulsion and then (2) applying a transition metal complex which reacts with the silver halide to form a silver complex and liberate transition metal ions which react with said organic compound to form a second, coloured complex. In a modification the silver salt is converted to a mercury salt before applying the metal complex. The silver halide image may be formed either by (i) imagewise exposing, and developing to form a silver image in the exposed areas and leaving silver halide in the unexposed areas or (ii) imagewise exposing, developing, fixing, and converting the Ag image thus formed back to silver halide. Images having integral masks may be formed by (a) using a coloured complex which dyes the areas not containing silver halide, or (b) after-treating the imaged material with a solution of a transition metal salt to form a coloured complex with the unused compound in the areas not containing silver halide. Multi-colour images may be formed from materials having three emulsion layers, each containing an appropriate organic complexing agent.
