Title: Battery charging circuits
IPC: H02J7/00
Filed: 1972-01-14
Abstract: 1399151 Battery charging systems WESTINGHOUSE BRAKE & SIGNAL CO Ltd 3 Jan 1973 [14 Jan 1972] 1979/72 Heading H2H A battery charger circuit which normally supplies a predetermined charge comprises timing means and means responsive to the charge condition of the battery during an initial time period which will stop the continuation of the predetermined charge if this would result in overcharging. The charging circuit comprises input terminals LN which are connected to a bridge rectifier via inductances L1, L2 and L3. The timing circuit comprises unijunction transistor T1 which via latch T2, T3, is arranged to enable gate T4 for the initial period. If gassing cell voltage, or other condition during the interval indicates overcharging might occur a more negative signal, appears on lead B which, via transistors T4, T5, T6 and T7 causes relay RL2 to release which releases relay 52 remains the shunt from across coil L1, so slowing down the charging rate. The charger also comprises a main timing circuit (not shown) which at the end of a first period (longer than the initial interval) applies a signal on lead C which also, via transistor T5, causes L1 to the placed in the charging circuit regardless of the charged condition. If during this first period, gassing conditions occur, a signal on line E, via transistors T9, T10, T11, releases relay RL1 which releases relay S1 and removes the shunt across coil L3 thus reducing the charging rate. At the end of a second period, a signal on lead D via transistors T14, T15, releases relay RL3 to release relay 53 which treats the charging circuit via contact 53/1. If the battery is removed, Zener diode Z1, via transistors T12, T13 senses the change in voltage to release relay RL3 via transistors T14, T15, to break the charging circuit at 53/1.

Title: Hinge fitting for a vehicle seat and a vehicle seat incorporating such a hinge fitting
IPC: B60N2/22
Filed: 1974-01-17
Abstract: 1450475 Adjustable backrests FRITZ  KEIPER 17 Jan 1974 [8 Feb 1973] 02346/74 Heading A4J [Also in Division E2] A hinge fitting for an adjustable backrest of a vehicle seat comprises a pawl 16 pivotally mounted on a side plate 12 and engageable with a step 13 on a side plate 10 to limit the range of pivotal movement of the backrest. The pawl 16 is normally pivoted into an inoperative position, shown in dash-dotted lines, by a loop spring 23. The abutment arm 17 of the pawl is therefore moved outside the path of movement of the step 13. In this condition the backrest can be inclined into a reclining position. If, however, a seat belt lock member 20 is inserted in a seat belt lock member 21 attached to the plate 12, the member 20 turns the pawl in a clockwise direction against the force of the spring 23 so that the abutment arm 17 projects into the path of movement of the step 13. This prevents the backrest being inclined beyond a predetermined range of pivotal movement. Actuation of the pawl may also be effected electromagnetically, pneumatically or hydraulically.

[Classes 40 (iii) and 40 (v)] In the parent Specification, a diode 30 is used to isolate the synchronizing signals which are fed to transformers 34, 35, one of which has an iron core, to separate line synchronizing impulses from the frame impulses. According to the present invention, the secondaries of these two transformers are connected to the deflection generators over chokes 44, 45 so that the heterodyne frequency, used in a superheterodyne stage in the receiver, cannot affect the generators by entering from the chassis which is a common earth. The diode is preferably gas filled with a hot cathode. According to the Specification as open to inspection under Sect. 91, the diode 30, Fig. 2 (Cancelled), may be connected to the detector 22 over two tuned circuits 38, 39, in parallel, tuned to the line and frame synchronizing frequencies respectively. The synchronizing impulses may also be applied to a resistancecapacity combination 46, 47, Fig. 1, to be used as automatic volume control potentials. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in emulsion coating of cellulosic films
IPC: C08J7/052
Filed: 1965-01-22
Abstract: Films of hydroxyethylcellulose and of regenerated cellulose are coated with a thermoplastic, hydrophobic resin by applying an aqueous emulsion of the resin to the film, evaporating off in less than 4 seconds the water before it can substantially penetrate the film by heating with infra-red radiation say in the range 3 to 4 microns, and then applying to the residual resin more intense infra-red radiation in the range 6 to 9 microns to fuse the resin and bond it to the film.  The hydroxyethylcellulose may contain ethylene oxide and a glycerine softener.  The resins may be copolymers of vinylidene chloride, vinyl chloride, acrylonitrile or methyl methacrylate, polyethylene, and polyamides together with organic solvent and surfactants, and in some cases toluene and/or isopropanol. Surfactants include polyoxyethylene-polyoxypropylene block copolymer; alkylarylpolyether derivative, nonyl phenol polyglycol ether alcohol; polyoxyethylene sorbitan monoleate.  The aqueous coating emulsions may include polyethylenamine as anchoring agent.  The coating may be heated to \sB 20 DEG C of the fusion point of the resin to bond the resin to the film.  Suitable emulsions contain 10 to 50% resin in water.  In the Figure (not shown) hydroxyethylcellulose base film having 4% of ethylene oxide is continuously passed from roll 1 through tank 3 containing the aqueous emulsion, between the rolls 4 to remove excess emulsion and then over rolls 5 to smooth the applied emulsion.  The coated film then passes through infra-red section 6 and heated with 3 and 4 microns radiation, the residence time being less than 4 seconds. Water vapour is vented to the atmosphere in section 7.  The film then enters infra-red section 8 where 6 to 9 microns radiation is applied to fuse the resin and effect chemical bonding, the residence time being 1 second, and finally cooled in an air chamber or by passing over chilled rolls before it is wound on roll 2.  The film is coated on both sides with the aqueous emulsion, or two contacting base films may be passed through the system in face-to-face contact to coate only one surface of each base film.
