Patent GB-425049-A (GB)
Title: Improvements in the treatment of improved materials containing collagen
IPC: C09D11/06
Filed: 1933-09-06
Abstract: Glue or gelatine is heated in mineral, animal, or vegetable oils having a boiling-point not lower than 130 DEG  C. at a temperature of approximately 130 DEG  C. until a mass of fibres separates from the glue leaving a phase of the glue dispersed in the oil.  When a lubricating oil is treated in the above manner, the lubricating properties of the oil are improved.  In processes of grinding, e.g. graphite, lampblack, carbon black and pigments such as zinc oxide, lithopone and white lead, the tendency of the powder to cake is minimized by the use of an oil vehicle containing 5 per cent glue. Polymerized oils and petroleum hydrocarbons may be used for this purpose.  The treatment of a polymerized linseed oil with glue in the above manner gives a product in which metallic powders such as bronze and aluminium are readily incorporated.  The interfacial tension in liquids such as liquid paraffin and Diesel oil is decreased by the incorporation of glue in the above manner and an improved fuel is obtained by mixing an oil so treated with an untreated fuel oil. Specifications 214,308, [Class 59], and 360,852, [Group V], are referred to.ALSO:Glue or gelatine is heated in mineral, animal or vegetable oils having a boiling-point not lower than 130 DEG  C., at a temperature of approximately 130 DEG  C., until a mass of fibres separates from the glue or gelatine leaving a phase of the glue or gelatine dispersed in the organic liquid.  When a lubricating oil is treated in the above manner, the lubricating properties of the oil are improved. In processes of grinding, the tendency of the produced powder to cake is minimized by the use of an oil vehicle containing 5 per cent glue and prepared by the above process, e.g. in the treatment of graphite, lampblacks, carbon blacks and pigments such as zinc oxide, lithopore and white lead.  Polymerized oils and petroleum hydrocarbons may be used for this purpose.  The treatment of a polymerized linseed oil with glue in the above manner gives a product in which metallic powders such as bronze and aluminium are readily incorporated.  The treatment of a transformer oil with glue in the above manner gives a product having increased di-electric strength and this may also be mixed with an untreated oil.  Similarly a dispersion of glue in a rubber resin prepared according to Specification 360,852 gives a product having an increased di-electric strength.  The interfacial tension in liquids such as liquid paraffin and Diesel oil is decreased by the incorporation of glue in the above manner and an improved fuel is obtained by mixing an oil so treated with an untreated fuel oil. The dispersion obtained by the above process may be passed through a colloid mill in accordance with Specification 214,308, [Class 59].

Title: Improvements in vehicle-carried electric lighting systems
IPC: H02J7/14
Filed: 1945-09-24
Abstract: 599,873. Self-contained supply systems. MANDL, A., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. Sept. 24, 1945, No. 24720. [Class 38 (iv)] Variable speed generators, with.-In a vehicle lighting system in which a variable speed alternator, e.g. an axle-driven inductor alternator, supplies a lighting circuit and also charges a battery which, at low vehicle speeds or standstill, supplies the same lighting circuit, one alternator output winding charges the battery while another winding or a tapped portion of the same winding supplies the lighting circuit at a lower voltage, substantially equal to the battery discharge voltage. In Fig. 2, the alternator output winding 1 charges, through rectifier 4, the battery 3 which can supply lamps 5 through contactor switch 8, while winding 2 (or alternatively a tapped portion of winding 1) can supply the lamps through contactor 7 and rectifier 6. The contactors may respond to vehicle speed, contactor 7 being closed only at speeds above a certain value ; contactor 8 may, however, operate on a fall of the battery charging current below a certain value. To avoid lamp flicker, the one contactor may close before the other opens. The alternator field winding 10 (which may alternatively be supplied directly by the battery) is shown connected across rectifier 6 in series with the automatic voltage regulator 9 which may be of the carbon pile type. For accelerating the decrease of charging current as the battery charge increases, there may be a saturable reactor 11 in series with the winding 1 and having a saturating winding 13 connected across the shunt 14 in the battery-charging circuit, with or without an opposing winding supplied at constant voltage through rectifier 6. In a modification, contactor 7 closes (when contactor 8 is open) to connect the lamps directly across the winding 2 for supply with A.C.

Title: The "pressure drop" testing of cigarettes
Inventor: GROPPE OCEE KEATON
IPC: A24C5/34
Filed: 1967-05-30
Abstract: 1,208,282. Testing cigarettes. AMF Inc. 28 May, 1968 [30 May, 1967], No. 24917/67. Heading A2C. In an apparatus for testing cigarettes for air leaks and/or defective filling, two side by side rows of single-length filter cigarettes 146 are fed from a transfer drum 144 into concave recesses of disc-shaped walls 66, 68, 70 and 82, 84, 86 mounted on cylindrical hubs (64, 80) respectively of two sections 30, (32) of a double testing drum, and are sealingly engaged at their filter ends for testing by a suction method; detected faulty cigarettes being subsequently ejected, while being transported through that segment of the drum's rotation lying between shrouds 150, 152, before the satisfactory cigarettes are discharged on to a conveyer belt 148. The cigarettes are held on the drum sections 30, (32) in the space lying between the shrouds 150, 152 by suction applied through four tubes 158. Each tube 158 includes a smaller tube 160 positioned within it for the application of an air blast to eject faulty cigarettes. Referring to the drum section 30, the cigarettes, after loading thereon, are contacted at their tobacco ends by pins (136) mounted on cam actuated members 120 and shifted axially to sealingly engage their filter ends with tapered bores 108 formed in a sealing ring 94. Alternate ones of the bores 108 communicate directly with openings 110 in the sealing ring 94 and the remaining bores 108 communicate with radially off-set openings 112. The openings 110, 112 communicate with arcuate recesses 114, 116 respectively when passing through the testing segment of the drum's rotation. The recesses 114, 116 are each connected to a separate pre-set testing suction supply and to a separate aneroid bellows switch (220). Actuation of either switch (220) by the pressure change caused by the presence of a faulty cigarette in the testing segment, in conjunction with a rotary control switch and memory control circuit, subsequently admits compressed air to the tube 160 to eject the faulty cigarette when it reaches the ejection segment. The ejecting air blast through the tube 160 may be replaced by a pneumatically actuated mechanical ejection system (320). Immediately prior to their reaching the ejection segment, the cigarettes are axially shifted out of engagement with the tapered bores 108 by an air blast fed to openings 200 in the sealing ring 94. The testing of the cigarettes on the other drum section (32) is effected in the same manner.

Title: Improvements in or relating to the plating of metallic surfaces
IPC: C25D11/02
Filed: 1957-08-07
Abstract: Prior to plating a metallic surface is electrolytically oxidized in an aqueous bath containing at least one compound of one or more plating metals to be deposited and a reducing agent, whereafter the surface is chemically or electrolytically plated. Preferably the metallic surface is connected in the electrical circuit before immersion in the bath and oxidation is effected with A.C., D.C., or pulsating D.C. to provide a coating of less than 20m  thickness.  The oxidation treatment may be employed prior to plating with copper, silver, gold, zinc, cadmium, chromium or nickel, especially on readily oxidizable metals such as aluminium, beryllium, iron, magnesium, titanium, uranium, zirconium or their alloys.  The bath may contain simple or complex salts of the metal to be deposited and as reducing agent one or more sulphites, thiosulphites, hyposulphites, arsenites or hypophosphites or lower valency salts of a multivalent metal, e.g. ferrous, titanous, cuprous, or stannous salts, or alcohols, aldehydes, hydrazine or hydroxylamine may be used.  The electrolytic oxidation may be effected in the same bath as the subsequent plating or in a similar bath of lower pH.  Typically an aluminium base alloy was polished, degreased in trichlorethylene, cathodically degreased in an aqueous solution of sodium phosphate and sodium silicate, neutralized with nitric acid, rinsed, and immersed as anode in an aqueous bath containing per litre 23 gms crystalline nickel sluphate, 24 gms sodium hypophosphite, 27 gms lactic acid, and 20 gms sodium succinate, the pH being adjusted to 4.7 with sulphuric acid or sodium hydroxide, to produce an oxide coating of thickness 0.8m .  After switching off, the article remained in the bath at 96-98 DEG C. for 1 hour whereby a nickel layer 22m  thick was deposited.  An aluminium article after degreasing with trichlorethylene, and chemical brightening in a bath containing phosphoric acid, nitric acid, and copper nitrate at 95 DEG C. followed by rinsing, was anodically oxidized in a nickel hypophosphite bath composed as above at 95 DEG C. but of pH 1.  Other pure aluminium articles, after trichlorethylene degreasing, etching in hot caustic soda followed by a neutralizing nitric acid dip and rinsing, were anodically oxidized in aqueous baths containing per litre 23 gms crystallized nickel sulphate, 27 gms lactic acid, 20 gms sodium succinate, and 9 gms formaldehyde or 10 gms pure ethyl alcohol or 56 gms neutral sodium sulphate crystals. Chemical plating of nickel to a thickness of 22m  was in each case effected as set out above for the aluminium alloy.
