Title: Method of producing composite bushings
IPC: B22D19/08
Filed: 1958-10-09
Abstract: 877,526. Making composite bushings; rotary work-holders; mandrels. GIEREN, H. Oct. 9, 1958, No. 32283/58. Classes 83 (2) and 83 (3). [Also in Group XXIII] In a method of making composite bearing bushings of steel lined for example with lead, bronze a steel cylinder having a length and diameter far exceeding that of the required bushing but with a substantially equal wall thickness in the bushing is lined on the inside with lead bronze by centrifugal casting during which deformations may occur in the cylinder, the latter subsequently being machined by turning on the inside to attain uniform thickness of the lining and finished on the outside before dividing into sections which are first pressed to form semi-cylindrical half-shells and then finished on the inside. The steel cylinder 1 may be produced from plate or seamless tubing. Concentric-cylindrical machining of the lining 2 is effected after the composite cylinder has been freed from scale by pickling and while it is held in true cylindrical form by a sectional clamping die 3. External finishing of the steel backing cylinder 1 is effected by a tensioned grinding belt 17 driven by a motor 20 (not shown), the composite cylinder being mounted in a sectional mandrel 7, e.g. of a non-ferrous metal, expanded by a conical shaft 10 rotated by a motor 11 (not shown). The shaft 10 is mounted in bearings suspended by arms 14 pivoted about a shaft 15, the cylinder thus being resiliently biased towards the belt 17 during grinding. The grinding belt 17 may extend the full length of the cylinder or may be of narrower width and move to and fro. After machining, the cylinder is cut up and the pieces pressed to form half-shells which are finished by broaching. In an example given, 120 bushing half-shells are produced from a cylinder 240 mm. long and 860 mm. in circumference, the steel backing being 1 mm. thick.

Abstract: 844,988. Potatoes, chipping &c. HOBART MANUFACTURING CO. Oct. 14, 1958 [Oct. 14, 1957], No. 32731/58. Class 5(1). Potatoes for chipping &c. are released one by one by a camactuated flap 80 from a hopper 25 into a screw conveyer 70 which is bodily rotated to deliver each into the pockets of a rotor 55 (not shown).

Title: Improvements in pile supports for sheet-feeding mechanism
IPC: B65H1/26
Filed: 1936-06-09
Abstract: 476,526. Feeding sheets. CROWN CORK & SEAL CO., Inc. June 9, 1936, No. 32790. Convention date, June 10, 1935. Divided out of 476,502. [Class 100 (i)] In a sheet - feeding apparatus for feeding sheets from a stack and forwarding them to a printing or like machine, the stacks are supported by transversely spaced chains 53, the lower ends of which hang free in such a manner that a second stack-holding platform 52 may be positioned upon the lower portions of the chains while a platform 52 is supported upon their upper portions. When a pile 51 is nearing exhaustion, a second pile of sheets 51a is placed upon a platform or skid 50a formed with legs 98 by means of which the pile may be moved transversely of the machine to a position in which the skid may be engaged by a pair of cross-bars 52 fitted with hook members 99, Fig. 5, of double form, the upper members 100 being engaged by cross-pins carried by the freely hanging endless chains 53 which depend from sprocket gears 90 against which the chains are held by rollers 93. The chains are driven step-by-step or continuously as described in Specification 476,502. The hook 101 is arranged so as to be just clear of a chain pin below the pin engaged by the hook 100, so that damage is prevented in the case of breakage of the upper hook or its pin, the pile being in that case supported by the lower hooks. To ensure correct side register of the sheets, a bend-end crow-bar 105 is inserted in one notch 104 of a plate 103 attached to the crossbar 52, and the skid 50a is moved to the left so as to register the left edge of the pile against a gauge bar 106. The pile is so placed on the skid that the edges of the sheet extend slightly beyond the left edge of the skid, and when the sheets contact with the gauge the inner runs of the chains are inclined slightly to the right, so that in their upward movements they tend to hold the pile against the gauge 106.

Title: Production of fumaric acid
IPC: C07C51/353
Filed: 1952-12-29
Abstract: The catalytic conversion of aqueous impure solutions of maleic acid is effected by heating in the presence of chlorine.  The solutions employed are those obtained as by-products in the production of maleic anhydride by the catalytic oxidation of hydrocarbons, e.g. benzene and in the production of phthalic anhydride by the oxidation of naphthalene.  Hydrochloric acid is the preferred catalyst but iodine, bromine, hydrochloric, hydrobromic and sulphuric acids, potassium thiocyanate and sodium bromide are mentioned.  The reaction mixture should contain 2 to 6 mols. of water per mol. of maleic acid and 0.05 to 0.08 mol. of hydrogen chloride per mol. of water.  Based on the weight of maleic acid, 1 to 3 per cent of chlorine is passed into the mixture at elevated temperature, when the fumaric acid is precipitated.  In order to obtain white crystals of fumaric acid, the crude aqueous maleic acid is heated with chlorine and activated carbon during the preliminary step of concentration and the passage of chlorine continued during the isomerization at reflux temperature. Examples are given.
