Abstract: 1151505 Electronic counters PLESSEY CO Ltd 8 Aug 1966 [13 Aug 1965] 34774/65 Headings G4D D7X D6Y D6C1 and D6C2 The dividing ratio of a frequency-divider can vary by one from one cycle to another whereby over a given number of cycles the effective ratio includes a fraction. The several denominations 1-5 of a decimal counter are set to count to predetermined digits, the attainment of its digit by the highest denomination 5 operating a reset stage 6 for the next denomination 4 and so on down to the lowest reset stage 6 which additionally issues an output pulse. The output of one of the reset stages 6 is also fed to a pre-set binary-coded decimal counter 9 which is arranged to issue from 0-9 pulses, each of which inhibits gate 8 so that the input from 7 is effectively reduced. The dividing ratio is thereby increased by this decimal fraction.

Title: Improvements in or relating to selectors for automatic telecommunication equipments
IPC: H01H63/24
Filed: 1947-12-30
Abstract: 634,911. Operating clutches : stopping shafts in predetermined positions. OLSSON, G. D., and BJORKMAN, N. F. Dec. 30, 1947, No. 34872. Convention date, Jan. 11, 1943. [Class 80 (ii)] [Also in Group XXXIX] In a power driven electric selector switch the contact arms are set in a fixed contacting position irrespective of their inter-step position at the time of the termination of the impulse applied to the electromagnet. The contact arms of the selector shown are driven via a toothed coupling member 12 which under the control of an electromagnet 17 is brought into engagement alternatively with a continuously rotating toothed driving member 9, and a toothed stop member 14, the teeth on the coupling member 12 and stop plate 14 being formed in such a way that the coupling member 12 when operated for moving towards the stop member 14, by the return spring 18 of the electromagnet is held in engagement with the driving member 9 until the teeth 26 on the coupling member 12 are located for complete engagement in the recesses between the teeth 27 of the stop member. Angular brackets 2 and 3 mounted on the base 1 carry the shaft 4 and locate longitudinally the sleeves 10 and 19 on the shaft ; sleeve 10 being secured thereto whilst sleeve 19 is free to rotate. The sleeve 11 which is also free to rotate on shaft 4 carries at one end the toothed coupling member 12 and passes through clearance holes in the stop member 14, and bracket 13. The sleeve 19 carrying the contact arms 20 is coupled to the sleeve 11 by the leaf spring 21, Fig. 4 (not shown), so that the drive may be imparted without interfering with the lateral movement of the sleeve 11 under the action of a fork 16 in the recess between flanges 15. A development of the teeth of the clutch and stop plate, Fig. 5, shows the teeth 27, on the stop member 14 in which curve 6 conforms to the path of the movement of the square teeth 26 of the coupling member. The distance between the stop member 14 and the driving member 9 is such that the coupling member 12 may only be disconnected from the driving member 9 when the teeth 26 face clearings 28, i.e. l1, exceeds l2 by nearly the height of teeth 24 and is smaller than l3 by the same amount. Should jamming occur the driving wheel 9 is longitudinally displaceable against leaf spring 8. The coupling wheel 12 may alternatively drive the contact arms 20 through a gearing.

Title: Improvements relating to amplifying apparatus
Inventor: HOLLOWAY DOUGLAS ROWLAND
IPC: G01R17/08
Filed: 1956-11-15
Abstract: 881,515. Electric tests. ELECTROFLO METERS CO. Ltd. Nov. 11, 1957 [Nov. 15, 1956], No. 34998/56. Class 37. In amplifying apparatus for producing, from a small input current, an output current which can be transmitted for operation of remote recording and measuring instruments, the moving coil system of a galvanometer comprises two coils N1, N2 fed respectively with the input current and with a fraction of the output current whereby the galvanometer operates as a current balance, deflection of the moving coil system being detected by an oscillator influenced by a coupling loop carried by the system. The coupling between oscillator coils L1 and L2, and hence the anode current of V1, is thereby dependent upon the input current; the anode current flows through coil N2 shunted by resistance R2, and through grid bias resistor R1 of an output stage V2 to vary its cathode current. Thus a fraction of the anode current of V1 and of the cathode current of V2 flow through N2 in reverse directions, the remainder flowing through R2; the net current through N2 and R2 constitutes the output current and is approximately proportional to the deflection of the moving coil system which depends on the opposing torques produced by N1 and N2. The resistor R2 may be of copper and manganin to provide compensation for resistance variation with temperature of the windings N1 or N2. Specification 616,551 is referred to.

Title: Polymeric coating compositions comprising polyolefines
IPC: C09D123/02
Filed: 1960-10-14
Abstract: A process for coating a surface with a polymer of an olefin comprises applying to the surface a suspension of the polymer in a liquid vehicle with a boiling range such that the greater part of the vehicle boils below the softening point of the polymer, the per cent by weight of polymer in the suspension being at least 80 and at most 115 times the apparent density of the dry polymer powder, the applied coating then being heated first at a temperature below the softening point of the polymer until the larger part of the vehicle has evaporated and subsequently being heated at above the softening point of the polymer to cause the polymer particles to fuse into a continuous layer.  Non-porous layers on vertical surfaces may be obtained from a single application.  In the examples polyethylene powders of apparent densities ranging from 0,20 to 0,42 g/cm3 are suspended in a vehicle comprising ethanol, hexylene glycol, cyclohexanone and water, and coatings are applied to preroughened degreased plates of deep-drawing steel by means of a spraygun. Heating is effected first at 110 DEG  to 120 DEG C. and then at 170 DEG C.ALSO:A surface coating composition comprises a polymer of a mono-olefin in suspension in a liquid vehicle with a boiling range such that the greater part of the vehicle boils below the softening point of the polymer, the per cent by weight of the polymer in the suspension being at least 80 and at most 115 times the apparent density of the polymer powder.  The polymer may be polyethylene and the liquid vehicle may be mixtures of water with alcohols, glycols, glycol ethers, glycol esters, ketones, aldehydes and/or amines, or may be a water insoluble organic liquid such as aliphatic or aromatic hydrocarbons.

Title: Improvements in and relating to metal carbonyls
IPC: C01G1/04
Filed: 1960-10-17
Abstract: Carbonyls of metals of Group VB, VIB, VIIB (except manganese) and VIII of the Periodic Table are produced by reacting at - 25 DEG  to 175 DEG  C. an anhydrous halide of a transition metal, an alkali metal, at least one aromatic hydrocarbon capable of forming an addition compound with the alkali metal, an ether solvent, and carbon monoxide gas under a pressure of at least 15 p.s.i.g.  The carbonyls produced have the formula M(CO)6(Cr, Mo, W); M(CO)5 (Fe, Ru, Os); M(CO)4 (Ni, Pd, Pt); M2(CO)12(V, Nb, Ta); M2(CO)10(Re); M2(CO)8 (Co, Rh, Ir).  Alkali metals used are Li, Na, or K and mononuclear carbonyls are formed directly in the process, but in producing binuclear carbonyls, intermediates such as NaV (CO)6 and NaCo(CO)8 are formed, which are decomposed to the carbonyl by aqueous acid. Aromatic hydrocarbons may be used in amounts of 1 to 100% mol. based on the amount of alkali metal. The ether solvent may be a cyclic aliphatic ether having not more than an average of 4 carbon atoms per oxygen atom, or a non-cyclic aliphatic ether containing a methoxy group and having not more than an average of 4 carbon atoms per oxygen atom. The alkali metal may be used as a dispersion in xylene or mineral oil, and is present in sufficient amount to reduce the metals forming mononuclear carbonyls to the zero valence state and those forming binuclear carbonyls to the minus one valence state, e.g. up to 10% stoichiometric amount.  Reaction time may be 1 to 100 hours and inert gas atmospheres, e.g. argon, nitrogen or helium may be used. The CO should be dry and free from oxygen.  The solvent is removed from the reaction mixture by evaporation, the solid residue is treated with aqueous acid and the carbonyl is recovered by extraction with a water-immiscible organic solvent, e.g. toluene, diethyl ether or by steam distillation.  Reference has been directed by the Comptroller to Specification 938,116.
