Title: Improvements in or relating to friction material
IPC: F16D69/02
Filed: 1931-02-17
Abstract: A friction material suitable for brake linings comprises asbestos, vulcanized rubber, and kaolin as a filler.  The material may, for example, contain: Asbestos fibre (45 per cent), magnesium oxide (3,6 per cent), rubber (18 per cent), sulphur (9 per cent), graphite (6 per cent), litharge (6 per cent), iron oxide (3 per cent), kaolin (9,1 per cent).  The sulphur combines with the rubber to cure it, the litharge and magnesium oxide accelerate the curing, the kaolin is a reinforcing agent and filler and has a low coefficient of friction, the iron oxide acts to age the composition.  In one process of manufacture, an equal weight of solvent such as naphthol or benzol is added to the rubber and the other ingredients are added to the softened rubber in a mixing machine.  The mixture is then extruded through a nozzle having roughly the desired size of the brake lining on to a conveyer belt enclosed in a hood through which a current of warm air is drawn to effect partial drying.  The extruder nozzle has a perforated plate whereby the asbestos fibres are roughly aligned in the length of the strip.  The strip is passed between rollers one of which has projections to perforate the strip to facilitate the subsequent further drying operation effected in a vacuum oven.  The strip is then passed through calender rolls to roughly form the material, cut into exact brake shoe length, placed in a flat mould and subjected to pressure and a temperature of about 300 DEG  F.  The strips are finally cured and curved by attaching to a drum placed in an oven at 350 DEG  F. and finished off to exact dimensions by grinding operations.  According to a dry process, the rubber and sulphur are first mixed cold in a machine of the Banbury type, the asbestos and other ingredients being then added and mixed and heated to render the rubber plastic.  The subsequent operations starting with that of subjecting the material to pressure and heat in flat moulds is the same as in the wet process.  The iron oxide litharge and magnesium oxide may be omitted.  To reduce the time of the drying operation, the material may be extruded in a very thin strip, a number of thicknesses being placed in the flat mould.

Filed: 1973-02-02
Abstract: 1463057 Motor vehicle warning devices LUCAS ELECTRICAL Ltd 18 Jan 1974 [2 Feb 1973] 5306/73 Heading B7H [Also in Division F2] In a motor vehicle a single warning device is actuated, when the engine is running, to indicate when the engine-oil pressure falls below a threshold value and, when the engine is stationary is also utilized to indicate when the engineoil level falls below a predetermined value. As shown, the warning device comprises a lamp 10 associated with supply lines 13, 15 a transistor 16 and switches 11, 12. With the engine running, switch 11 opens when the oil pressure reaches the required threshold value; should the pressure drop below this value however, the switch closes to energize the lamp 10 by way of supply lines 13, 15, the transistor 16 and resistor 17. With the engine stationary the switch 11 is closed and the arrangement is such that the transistor 16 is rendered conductive, by base current supplied by way of a resistor 34 and diode 35, when the normally closed switch 12 opens in response to the sensing of a low engineoil level, whereby the lamp 10 is energized to indicate this state. The transistor 16 is conditioned to respond to switch 11 when the engine is running and to switch 12 when the engine is stationary by a transistor circuit 18-33 connected to its base, the circuit also being connected to the vehicle battery over line 13 and ignition switch 14, to earth over line 15 and switch 11, to the contact breaker for the engine over line 24, and to a line 38 over which a timed signal may be applied when the ignition switch is closed to test the integrity of the arrangement. The lamp 10 may be replaced by a buzzer, the transistor 16 by a thyristor, and an electronic switch may be connected across switch 12 to inhibit oil-level response when the engine temperature is high, a circuit incorporating these modifications being described with reference to Fig. 2 (not shown).

Title: Impulse-type electromagnetically actuated devices
IPC: H01H50/20
Filed: 1961-02-14
Abstract: 980,686. Electromagnets. W. W. CLEMENTS. Feb. 14, 1961, No. 5501/61. Addition to 854,030. Heading H1P. [Also in Division H2] The armature of an electromagnet is moved between two stable states by means of an auxiliary member of magnetic material which, when the coil is energized, moves to a position which alters the configuration of the magnetic circuit such that the armature is attracted to its other stable state and, when the coil is deenergized the auxiliary member returns to a neutral position. The electromagnet comprises a coil 15, enclosed in a magnetic housing comprising sleeve 17 and end-plates 16A, 16B, which surround armature 6 of magnetic material which is attached to shaft 8 by pin 7. Attached to one end of the shaft is a bi-stable spring 12 held at its periphery in clamps 13. Loosely disposed on the shaft are members 19A, 19B of magnetic material joined together by a non-magnetic spacer (not shown) and located between plates 23A, 23B which are resiliently attached to the end-plates 16A, 16B and capable of displacement in slots 24 in brackets 9A, 9B. As shown, the armature 6 is in its bottom stable position and the auxiliary member is in its neutral position with plates 23A, 23B lying in the base of slots 24. If coil 15 is energized member 19B is attracted to the lower side of armature 6 thereby increasing the effective flux in the top air gap 18A so that the armature moves upward to its top stable position, Fig. 5 (not shown). Member 19B remains attached to the armature until the coil 15 is de-energized when the auxiliary member is returned to its neutral position under the action of spring 22A. Application of a further current pulse causes top member 19A to be attracted to the armature which is displaced to its lower stable position shown, the auxiliary member returning to its neutral position when the coil is de-energized. The end faces of the armature may be coated with non- magnetic material, e.g. brass, to ensure release of the auxiliary member. The embodiments of the bi-stable electromagnet shown in Specification 854,030 may be modified so that the auxiliary member returns to a neutral position when the coil is de-energized.
