Title: Improvements in or relating to magnetic electric switches suitable for use as leveling units for elevators
Inventor: BECK WALTER
IPC: B66B1/50
Filed: 1956-04-30
Abstract: 787,003. Magnetic switches; control of motors. MONTGOMERY ELEVATOR CO. April 30, 1956, No. 13224/56. Classes 38 (3) and 38 (5). A switch intended for use as a floor levelling device in a lift control system comprises a non- magnetic casing 35 pivotally supporting at 44 a member 45 carrying a horseshoe magnet 48 having its poles facing like poles of a bar magnet 40 carried by a casing bracket arm 39 in front of a non-magnetic casing cover 36. The mutual repulsion between the magnets normally holds the member 45 in the stable position, shown, in which a pair of contacts 51 thereon are disengaged from a pair of fixed contacts 54, the magnet 48 being tilted to cause engagement of the contacts by the positioning of a magnetic plate 33a between the magnets. Stop screws 49, 50 limit the tilting of the member 45. In use, a pair of such switches are mounted one above the other a short distance apart on the lift cage and co-operate with magnetic plates 33a arranged in the lift shaft at each floor level, the length of the plates being slightly less than the distance between each pair of switches whereby only one switch of a pair may be operated at one time. Depending on which switch is closed the levelling motor is driven in one direction or the other whereby the lift is brought to a position in which the plate 33a at the particular floor level is between both switches and both switches are open (Figs. 9-11, not shown).

Title: Production of polyamic acids
Inventor: VAUGHAN MERVYN FRANCIS
IPC: C08G73/10
Filed: 1966-11-04
Abstract: 1,207,485. Polyamide acids; polyimides. NATIONAL RESEARCH DEVELOPMENT CORP. 19 Oct., 1967 [4 Nov., 1966; 21 March, 1967],Nos. 49608/66. and 13244/67 Heading C3R. Polyamide acids are prepared by condensation of an aromatic dianhydride with an aromatic diprimary amine in a water miscible organic liquid medium in which the reactants are sufficiently soluble to polymerize in the liquid phase but in which the resultant polyamide is insoluble. Polymerization is carried out, at least in the latter part of the reaction in the presence of a minor proportion of water. This may be present in a quantity, e.g. up to 4% by volume, such that the polyamide is precipitated but the product is of a higher M.W. than a corresponding polymer prepared in the absence of water. Alternatively, a higher proportion of water may be present, e.g. 4-15% by volume, in which case the resultant polyamide acid remains in solution. Suitable solvent media are: acetone, methyl ethyl ketone, tetrahydrofuran, dioxan, or diethyleneglycol dimethyl ether. A small quantity, e.g. up to 10% v/v, of a more polar solvent, e.g. dimethylformamide, may also be present. Reaction may be started under anhydrous conditions, e.g. by mixing the solid reactants or using slurries or solns. of anhydrous solvent, the water being added at a later stage, possibly as an aqueous amine soln. Suitable dianhydrides are pyromellitic dianhydride and 3,31,4,41-benzophenone tetracarboxylic dianhydride. Examples of diamines are: 4,41-diaminodiphenyl-ether, -methane, or -sulphone and m- or p-phenylene diamine. The polyamide acids may be spun into fibres by conventional means and may be converted, by thermal or chemical treatment, to polyimides.

[Class 136 (iii)] [Also in Group XXV] In a folding cycle frame a hinged joint between two tubular members 10, 23 of the frame is formed by means of fittings 30, 31 one on each member, each fitting carrying a number of hinge plates 43, 44, 45 which fit between hinge plates 46, 47, 48 of the other fitting and are joined together by a hinge bolt 56 and so arranged that the ends 49, 50 of the plates bear upon surfaces at the bottom of the spaces between adjacent plates when the members are in the unfolded position and a latch member 61 holds the joint in this position and forces the ends against the surfaces on which they bear. An end portion 68 of the latch engages slots 58 in the hinge plates. The latch member is pressed towards the locking position by a hollow plunger 72 carried in an extension 82 of the fitting 30 and urged outwardly by a spring (not shown). In the case of a hinge for a cycle member inclined to the axis of folding the fittings 30, 31 are bent to enable the axis of the joint to be in the correct position. The latch opens automatically during unfolding of the tubular members and slips into a locking position when the unfolding is completed. The opening is effected by an edge of the hinge plates of one fitting engaging with a curved end of the latch. In Fig. 1 (not shown) a cycle frame has joints in an upper and a lower frame member so arranged that the cycle can be folded into a position in which the back wheel is beside the front wheel.

Title: Process for treating baking flour
IPC: A21D2/04
Filed: 1930-05-03
Abstract: Flour is treated with a sufficient quantity of perphosphates to render available a sufficient quantity of oxygen for bleaching the flour and also, after the bleaching operation has been stopped, to exert a direct raising action during the baking process. Perphosphates of the alkali metals and of calcium have been found suitable and may be added to the finished flour or during or before milling.  The addition may be by mixing or by injection or sprinkling in the state of solutions or suspensions.  The liberation of the oxygen for bleaching may be accomplished by warming the flour to a temperature of about 65 DEG  C., and arrested by rapidly cooling and aerating the flour.  Calcium sulphate or similar salts may be added in small quantities to accelerate the liberation of the oxygen.ALSO:Flour is treated with a sufficient quantity of perphosphates to render available a sufficient quantity of oxygen for bleaching the flour and also, after the bleaching operation has been stopped to exert a direct raising action during the bleaching process.

Title: Improvements in or relating to the treatment of titaniferous material
IPC: C01G23/00
Filed: 1923-05-24
Abstract: Titaniferous material such as ilmenite is treated with hydrofluoric acid and, after separation of the residue, an oxidant such as hydrogen peroxide is added to oxidize the ferrous iron. Potassium hydrate is then added to precipitate potassium fluotitanate, fluozireonate, and fluosilicate.  The precipitate is treated with hot water which dissolves the fluotitanate, and titanium oxide is precipitated from the solution by adding potassium hydrate, ammonium hydrate, ammonium carbonate or the like.  The fluozirconate and fluosilicate may be treated to recover hydrofluoric acid, zirconia and silica.  The ferric fluoride solution remaining from the first operation may be treated with calcium chloride to obtain calcium fluoride and ferric chloride or with potassium hydrate to obtain potassium fluoride and ferric oxide, and the potassium fluoride may be treated with lime to obtain potassium hydrate and calcium fluoride.  Specification 10175/14 is referred to.
