Title: Improvements in and relating to nibs of ball point pens
Inventor: FEHLING HANS REINHARD
IPC: B29C45/00
Filed: 1959-10-02
Abstract: The nib portion of a ball-point reservoir pen is made by injection moulding with a material comprising a thermoplastic substance loaded with at least 20% by volume with a finely dispersed solid filler which has an elasticity modulus in compression of not less than 2X106 lbs. per square inch, and has a melting point above the moulding temperature of the thermoplastic material, the elasticity modulus in compression of the resultant moulded material being not less 6X105 lbs. per square inch and preferably more than 8X105 lbs. per square inch. The thermoplastic substance has a compression modulus of not less than 1X105. Examples of thermoplastics are synthetic polyamide resins, such as nylon or polyhexamethylene-sebacamide, and polycarbonate or acetal resins, such as polycarbonic acid ester of 4,4-dihydroxydiphenyl-2, 2 propane. The filler may comprise minute beads of copper, aluminium, glass, or mica, and where copper is used, the beads may be silver plated. Small quantities of pigments and graphite or molybdenum disulphide may be added. In one example, a powdered matrix of polyhexamethylene-sebacamide having a compression modulus of 3X105 lbs. per square inch when completely dry, is mixed with 45% of a filler of electrolytic grade pure copper powder in bead form and particle size 0.0001 inch to 0.0015 inch, such that the injection moulded material has a compression modulus of 11X105 lbs. per square inch. In other examples, the filler consists of 51% of glass powder in bead form, or 11% of mica powder in flake form.

Title: Transfer materials
Inventor: LYTHGOE ALAN LENNOX
IPC: B41M5/10
Filed: 1964-08-18
Abstract: In a transfer of the kind consisting of a carrier sheet, a releasable film layer on the sheet, and a pressure-sensitive adhesive superposed on the film layer, the adhesive comprises two components present as discrete phases and which, subsequent to the transfer of the film layer to a receptor surface, can be treated by heat to convert the discrete phases to a single phase and thus increase the strength and the heat-resistance of the adhesive bond.  The film layer is in the form of separate letters, symbols &c., each separately transferable by pressure, using a stylus and, in some cases by stretching the carrier sheet as described in Specification 959,670.  The carrier sheet, which may be rigid or flexible, or may be transparent, can comprise paper, plastic film, metal foil or laminate material treated to cause the film layer to adhere thereto but to be releasable.  A detachable paper sheet may be provided to protect the transfer before use.  Suitable inks for forming the film layer and which may be applied by screen or gravure printing, are as follows:  Example 1. Cellulose nitrate in ethylene glycol mono-isopropyl ether acetate, castor oil glyceryl sebacate, dimethylcyclohexyl adipate; Example 2. Polyamide resin, plasticizer, carbon black, butyl alcohol.  For the adhesive, the following compositions are described:  Example 1. Aqueous emulsions of terpene resin, polyvinyl butyl ether, and copolymer of butyl and methyl acrylates, and an aqueous solution of methyl cellulose are mixed; Example 2.  A mixture of (a) aqueous emulsions of terpene resin and polyvinyl ethyl ether and (b) an aqueous emulsion of a copolymer of butyl and methyl acrylates, and aqueous solutions of methyl cellulose and polyethylene glycol.

Filed: 1974-07-31
Abstract: 1475575 Automatic exchange systems RELIANCE TELECOMMUNICATION ELECTRONICS CO 31 July 1974 [31 July 1974] 33806/74 Heading H4K A relayless switching circuit comprising only passive elements and two terminal diode devices is used to couple a telephone subscriber's line to a source of A.C. ringing current and a speech transmission circuit. The switching circuit supplies pulses of D.C. ringing current to the line on energization of the ringing current source whilst electrically disconnecting the speech transmission circuit. To ring the substation a ringing control signal is used to turn on generator E AC . On negative half cycles of the ringing current diode 44 conducts and Zener diode 46 remains cut off, thereby resulting in the voltage across the ringing circuit 20, 22 remaining at + E B , the battery potential. On positive half cycles capacitor 42, and diode 44 act as a voltage doubler to cause the breakdown of Zener diode 46 so as to supply a positive pulse of ringing current to the ringing circuit 20, 22. Diode 36 acts to decouple the speech transformer circuit 30 for the line during the positive ringing pulses. Conventional ring trip circuitry may be used to cause the ringing generator 40 to be switched off.

Title: Inspection apparatus
Inventor: SKINNER RAYMOND SEARLES
IPC: H01J9/42
Filed: 1958-10-24
Abstract: 845,341. Photo-electric lamp inspection. SYLVANIA ELECTRIC PRODUCTS Inc. Oct. 24, 1958, No. 34194/58. Class 40(3). In apparatus for inspecting electric discharge devices (fluorescent lamps) the energized lamps are conveyed past a series of photo-electric . inspection stations each sensitive to either the intensity or spectral contents of the light emitted, defective lamps produce a change in the charge on a condenser memory device which operates a reject mechanism. The motor 15 drives, via the Genero-mechanism 17,18 and 19 the conveyer 10 and the ageing rack 11, and via the pulleys 32 the condenser memory disc 31. The lamps which are energized on transfer to the ageing rack move past the photo-electric devices 21, 22 and 23 where their light emission is examined and thence to the conveyer 26, or if found defective via the door 27 (in dotted position) to the reject bin. Each commutator segment is associated with one of the last 16 index positions on the ageing rack. As a lamp moves past position 38<SP>1</SP> its associated condenser 38 on the memory disc receives a charge of - 4 volts from contact 41. One and a half index positions later the lamp is inspected by the photo-electric device 21 and condenser 38 is connected to contact 42, the lamp is similarly inspected at position 22, condenser 38 to contact 43 and at position 23, condenser 38 to contact 44. If the lamp is in order no change takes place in the charge on the condenser, if, however, the lamp is found defective at any of these positions the condenser is charged to +3 volts. One and onehalf index positions after the final inspection at position 23 the lamp leaves the ageing rack and the charge on the condenser 38 is sensed by the contact 45 which is connected in the grid circuit of a valve controlling the operation of the door 27. If the charge is positive, indicating a defective lamp, the valve fires and opens the door to the reject bin.
