Abstract: 1,136,316. Polyamides. VICTOR WOLF Ltd. 18 April, 1967, No. 17631/67. Heading C3R. [Also in Division B2] Polyamides are derived by condensation of a predominantly dimerized fatty acid together with some aliphatic monocarboxylic acid with isophorone diamine or a mixture thereof with an aliphatic polyamine in substantially equivalent proportions of carboxyl to amine groups, the major proportion of the carboxyl groups being contributed by the polymeric fatty acid. The acids may be used in the form of anhydrides or esters. The monocarboxylic acid may be a straight or branched chain acid having up to 18 carbon atoms and may be substituted (e.g. lactic acid). Up to 15wt. per cent of aliphatic dicarboxylic acids, e.g. sebacic or adipic, may also be used. Specified aliphatic polyamines are ethylene and propylene diamines, diethylene triamine and triethylene tetramine. The resins are soluble in methylated spirits and may be used for printing inks, adhesives and coatings. The products of the examples had acid values from 2À9 to 6À4, amine values from 2À2 to 6À4 and softening points from 80 to 138. In Examples 8 and 9 the resins are used with TiO 2  and (9 only) nitrocellulose to formulate printing inks. Reference has been directed by the Comptroller to Specification 976,007.

Title: Improvements in or relating to the purification of alcohols
IPC: C07C29/74
Filed: 1950-07-18
Abstract: Impure alcohols such as Oxo alcohols, in particular primary alcohols of C4-C12, and especially octanols and nonanols used in preparing carboxylic diester plasticizers, are freed from sulphur-containing and colour-forming impurities by contacting the topped alcohol at 25-180 DEG  C. with an oxide of Hg, Mn or Pb.  Air must be present if the oxide is in a low state of oxidation.  The alcohols are contacted in liquid phase with the solid oxide which may be finely-dispersed or in the form of a bed on an inert support.  Conditions are generally neutral or slightly alkaline.  The treatment time is usually 1-2 hours and the amount of oxide about 10-50 per cent of the weight of alcohol.  After removal of oxide, the alcohol is redistilled.  In examples, topped iso-octyl alcohol is treated with Pb3O4 or HgO or with PbO, HgO or MnO2 and air.  The purified alcohol is esterified with phthalic anhydride in the presence of stainless steel strip giving esters of good colour.

Title: Lock out circuit for automatic telephone exchange
Inventor: DELANOY DONALD BRIAN
IPC: H03K19/084
Filed: 1960-05-25
Abstract: 967,256. Automatic exchange systems. PYE Ltd. May 24, 1961 [May 25, 1960], No. 18474/60. Heading H4K. In an exchange in which calling and called subscribers are connected electrically to one of a plurality of links, a lock-out circuit, comprising a transistor operated over a diode or-gate from the links, is provided which is operable to prevent a calling subscriber from being connected to a link when all the links are busy. As shown, positive potentials are applied to rectifiers MR1 . . . MR3 when associated links are busy. This cuts off transistor T1, so that T2 is also cut off and T3 conducts. Terminal 4 may now assume any negative potential, so enabling a subscriber to connect to a link. When all links are busy, however, T1 conducts, the resulting current through R1 to point 4 causing T2 to conduct and T3 to cut off, the latter increasing the value of the negative potential applied to the base of T1 to ensure that it stays conducting irrespective of a link becoming free. With T1 conducting, the point 4 is clamped to a point near earth potential and this disables cold cathode tubes which connect the subscribers to the links. A subscriber can only seize a free link when it becomes free by first hanging up, whereby point 4 is disconnected so that T2 cuts off, whereupon T3 conducts to cut off T1. The lock-out circuit described in Specification 967,252 is also described.

Title: Mechanism for orienting strip ends for splicing
IPC: G03D15/04
Filed: 1970-04-17
Abstract: 1306423 Splicing films EASTMAN KODAK CO 17 April 1970 [21 April 1969] 18509/70 Heading G2C In a device for splicing together strip material, e.g. film strips, the two ends to be joined are oriented into their correct positions by a positioning means which is then withdrawn. As shown, the device comprises a base-plate 6 having guide rails 8 and a transverse ribbed support plate 10. A flexible spring member 16 has one end screwed to the base-plate, and its other end acts as a clamp to hold a sheet or strip firmly against the baseplate. Magnets (14, 14'), Fig. 1, (not shown), in member 16 and base-plate 6 enhance the clamping effect. A plate 24 is pivotably and slidably mounted on a rod 26, and can pivot or slide from the full line to the broken line position. One side is flanged downwardly as at 30, the flange resting against plate 6 in the full line position. Another side has a step or shelf 34, and in the full line position this shelf is spaced above the plate 6. In use, a leader strip 12 is placed on plate 6, its rear end positioned and clamped under member 16. Its forward end, which is to be spliced to a film strip, rests on the ribbed plate 10, and a strip of adhesive tape 25 laid across it. The assembly may be coated and stored for future use. Otherwise, it is removed, inverted, and  replaced, so that the back of the tape now rests against the ribbed plate 10. Plate 24 is now moved to its operative (i.e. full line) position, and the end of the film roll 23 positioned on the shelf 34. It is now located in the correct position for splicing. Plate 24 is slid away in the direction of the arrow, and the end of film 23 is pressed downwards into engagement with the adhesive tape 25, which now joins film and leader together.

Title: Method of and means for producing sound records and metal matrices therefrom
IPC: C25D5/56
Filed: 1929-06-17
Abstract: 335,181. Watson, H., and Good, J. June 17, 1929. No Patent granted (Sealing fee not paid). Records, duplicating; tape records ; sound grooves and traces.-A strip metal matrix for usein the production of ribbon sound records is made by recording sound waves in a helical track in a layer of wax carried by a cylindrical member. After recording, the surface of the cylindrical carrier is made electrically conductive, as by treating it with powdered graphite or like material, the adjacent convolutions of the helical sound track being insulated from one another as by skimming off the graphite along a narrow helical path. The cylindrical carrier is then mounted vertically or horizontally in a vessel containing an electrolyte comprising a solution of the metal of which the matrix is to be formed, and the metal, e.g., copper, is deposited electrolytically upon the carrier. The latter may be rotated during this operation, after which the metal matrix is stripped therefrom in ribbon form. In a modification, a ribbon of wax having a backing of inextensible and flexible material, e.g. textile material or metal, is wound helically upon the cylindrical carrier. The sound record is then impressed or cut in the wax, after which the negative metal matrix is made as previously described. The adjacent convolutions of the helical wax ribbon may be insulated laterally from each other by separating them by a helical rib of insulating material formed on the peripheral surface of the rotary carrier. Two or more helical sound records may be formed side by side in the wax coating or, after the first helical record track has been made, a second track may be cut starting from the end of the first track, the cutter being first moved slightly laterally of the wax cylinder and the cut being made in a backward direction, the same operation being repeated at the end of the second record, and so on. In another modification, the sound-record track may extend transversely in a zig-zag manner across an imaginary helical path of wax corresponding to the width of the strip metal matrix to be formed.

Title: Improvements in or relating to circuit arrangements for automatically distributing incoming telephone calls amongst a plurality of switching positions in trunk telephoneexchanges
IPC: H04Q3/00
Filed: 1959-06-01
Abstract: 892,833. Exchange systems. SIEMENS & HALSKE A.G. June 1, 1959 [June 25, 1958], No. 18622/59. Class 40 (4). Incoming calls at a trunk exchange are distributed to operators' positions over selectors RWI, RWII by means of common apparatus which pre-selects the position to receive the next call and sends numerical signals to the selectors to set them accordingly. The testing equipment Um comprises a no-normal switch of which the contacts are connected to the operators' positions P11... Pln through relays X1 ... Xn. A position is not selected if it is unattended or if all its connecting circuits VG are in use. When a line F1 is seized the incoming relay set An becomes connected to a register Sp which takes into use the testing equipment Um. In accordance with the X relay operated code signals, e.g. in binary form, are sent to the register Sp which effects the setting of the selectors by means of markers ESI, ESII. The selectors may, for example, give access to 225 positions each with 15 connecting circuits. If no idle connection circuit is found, the equipment Um is seized again and the action is repeated. An operator may transfer a call to another position by sending back a signal to reseize a register and energize relay R, followed by signals indicative of the desired position. The register Sp tests over wires y the condition of the position, and if it is available seizes the part b of the equipment Um to obtain routing digits for resetting the selectors RWI, RWII. If the desired position is unavailable the order remains stored in the register. If an incoming call is to be routed to a particular position, relay R is energized by a prefix signal and routing is effected by subsequent digits as in the case of a transferred call. The testing equipment Um can be arranged to preselect the position having the most connecting circuits available. Specification 772,267 is referred to.

Title: Improvements in or relating to methods of and apparatus for drying inked impressions
IPC: B41F23/04
Filed: 1936-07-04
Abstract: 474,095. Drying printed sheets. STEVENS, A. H. (Steel Engravers Appliance Corporation) July 4, 1936, No. 18626. [Class 34 (ii)] Inked impressions, particularly those printed from steel engraved plates, are dried by subjecting them to radiant heat while maintaining the atmospheric temperature on all sides of the sheets constant by circulating the air surrounding the sheets in an enclosed circuit. The sheets are carried through an oven 10 by a conveyer-band 29 and pass under pairs of electric heaters 35, 39 partly enclosed by curved reflectors 45. The heaters 39 are maintained at a temperature of about 600‹ F. and form the main source of heat for the oven and for drying the sheets, while the heaters 35 are controlled by a thermostat 36 so as to maintain the oven at between 150 and 250‹ F., according to the setting of a switch 38. The air inside the oven is kept in circulation by means of a fan 52, the outlet 54 of which is divided and communicates with a passage 53 between brackets 42 from which the heaters and the reflectors are supported. The air is thus forced down on to the centre of the sheet and then outwards towards the edges thereof. The walls of the upper portion of the oven are insulated so as to bring about an even distribution of the heat. After drying, the sheets travel in a vertical path to a receiver 95. In a modification, the fan is wholly outside of the oven, and air is admitted to the intake pipe to humidify the air inside the oven ; also, a radiator is provided in the outlet from the fan for regulating the temperature of the air, and a vent tube is provided for diverting some of the air so as to reduce its velocity.

Abstract: 1,140,695. Electrostatic generators. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. 28 April, 1966 [28 April, 1965], No. 18694/66. Heading H2A. In an electrostatic generator in which a graded potential is produced between spaced electrodes 36 by means of a voltage-distributing ring 38 of high resistance, arcing between the electrodes and the carrier ring is prevented by shaping the electrode, e.g. with a bevelled edge, so that it does not form a re-entrant surface where it joins the ring, and in addition, resistive or insulating beading 39 is placed over the edge of the electrodes. This material may be a silicone rubber elastomer, or an epoxy resin having a resistivity substantially lower than that of ring 38. This ring may be made of conductive glass or plastic. If desired, Fig. 6, not shown, the beading material may extend across the surface of the carrier ring, and this may, in turn be covered with an insulating layer. Alternatively the plate electrodes may, themselves, be of semiconducting material, e.g. of a mixture of carbon and rubber. The machine may be of insulating or conducting charge-carrier type.

Title: Improvements in or relating to coin checking apparatus
Inventor: PORTER CHARLES BENJAMIN ALBERT
Filed: 1963-05-11
Abstract: 1,101,421. Testing coins. AUTONUMIS Ltd. 10 Aug., 1964 [11 May, 1963], No. 18757/63. Heading G4X. Mechanism for testing coins for diameter, thickness, weight, and the presence of a rim and a milled edge, comprises a rail 5 which delivers a coin into a cradle comprising a platform 12 and pawl 16 on a member 10 pivoted at 11 on the outside of a back plate 1, the elements 12 and 16 moving in slots 13, 15 in the plate. Too thin a coin falls between rail 5 and plate 6 along reject path 9. A coin of too small diameter passes between elements 12, 16 along a reject path 9<SP>1</SP>. Too thick a coin is arrested by an adjustable stop 8, being released along path 9 by a reject button (not shown) which eases plate 6 away from rail 5. Member 10 is weighted at 17, so that a coin of sufficient weight rocks the member to deliver the coin on to rail 20. A coin of insufficient weight is retained, and pulled off the cradle to follow reject path 9 by the reject button by a finger 18 on plate 6 working in a slot 19 in plate 1 behind the coin. A coin of acceptable diameter but without a milled edge contacts a nose 16a on pawl 16 and raises it, passing on to reject path 9<SP>1</SP> Milling on the edge, however, is engaged by nose 16a to arrest the coin. A coin so far acceptable, rolls down rail 20, and passes between spring- biased balls 24, 26. If the coin has no rim, it passes on down a reject path 9<SP>11</SP>. If it has a rim, however, the balls temporarily retain the coin, which swings about its point of contact with the balls until it abuts a stop so placed that the inertia of the coin frees it from the balls, and it follows an accept path 35. The spacing and spring bias of the balls may be adjustable, and the spring bias may be replaced by magnetic attraction between the balls.
