Title: Preparation of oestrogenic hormones
Filed: 1949-08-16
Abstract: Water-soluble oestrogenically orally active substances contained in substantially unhydrolysed equine urine are extracted by means of an organic solvent consisting of an alcohol or a ketone having a water solubility of less than about 6 per cent to cause separation of the water soluble oestrogenically orally active substances into the said solvent and obtaining from the solvent a product containing said substances.  As solvent there may be used hexenol and the product may be obtained from the solvent extract by concentration.  Prior to concentration the solvent extract may be washed with alkali hydroxide.  The concentrate may be precipitated by the addition of a lower aliphatic hydrocarbon, e.g. hexane.  Detailed examples are given. Specifications 600,658 and 645,414, [both in Group VI], are referred to.

Title: Improvements in Methods of Manufacturing Printed Circuits
IPC: B23K26/18
Filed: 1968-05-07
Abstract: 1,194,112. Printed circuits; lasers; electron beam apparatus. INTERNATIONAL BUSINESS MACHINES CORP. 7 May, 1968 [29 May, 1967], No. 21552/68. Headings H1C, H1D and H1R. [Also in Division C7] In the manufacture of a printed circuit, a substrate of pyrolyzable polymeric material is exposed to a radiant energy source in a predetermined pattern to form a conductive pyrolyzate pattern which is subsequently metallized. In the embodiment, a layer 1 of copper is coated with a substrate 2 of epoxy resin varnish which is exposed in predetermined areas to a laser beam, Fig. 2 (not shown), to form the conductive pattern, the degree of conductivity of the areas being determined by the energy density of the beam at the substrate and the depth of penetration of the conductive areas, e.g. to provide pin points 3 penetrating the substrate to the copper base and a superficial area 4 forming a capacitor plate with a connection 5, depends on the dwell time of the beam. These pyrolyzate areas are then electrolessly plated and subsequently electroplated or electroplated directly, using a photoresist subse quently removed by a solvent. A second polymeric film 6 is then applied to the first film 2 and additional conductive areas e.g. pin points 3, capacitor plate 7 formed and metallized as before. A resistive element 6 is also provided by masking the pyrolyzate area during metallizing. Further polymeric films may also be applied with connections and elements as required, a magnetic element 10 being formed by plating a circular pyrolyzate pattern with magnetic material e.g. nickel, nickel-cobalt alloy, or cobalt, nickel-iron alloy. The layer 1 of copper may be etched to form an additional circuit or removed leaving only contact lands for the circuit. Alternatives.-The layer 1 may be of ceramic, glass or epoxy-glass laminate. The radiant energy source may be an electron or laser beam. Using a laser a substrate coated with the polymeric material is mounted in a support programmed to move in mutually perpendicular directions. If an electron beam is used its focusing and deflection are programmed to inscribe the required pattern.

Filed: 1924-09-15
Abstract: 244,813. De Havilland Aircraft Co., Ltd., and Hagg, A. E. Sept. 15, 1924. Steering and balancing.-A device of the character described in Specification 219,388 wherein a movable marginal portion of a wing is elastically controlled to enable the camber or incidence of the wing to vary automatically with the air speed without interfering with the pilot's control over those portions, has a modulating device for ensuring that the force exerted by the elastic control upon the movable member decreases or is substantially constant as the member moves to reduce the camber or incidence. Fig. 4 shows a perspective view of a device mounted upon the wing framework for controlling a flap extending along the rear edge of the wing. The flap is connected by a rod 24 to a crank 23 mounted on a spindle 20 passing through one arm 18 of a bellcrank lever pivoted about a spindle 16 to a bracket on the wing. The lower end of the spindle 20 has an arm 21 connected by a link 22 to a double-armed lever 17, also pivoted about the spindle 16, and the ends of these arms are connected by cords 32 to a corresponding lever at the other side of the machine and to the pilot's control lever. The arms 23 on the two sides of the machine are arranged as described in Specification 184,317 in order that the movements of the flaps, when moved in opposite directions by the pilot, shall be unequal. The arm 18 is integral with a double armed lever 19 connected by crossed wires 34 to a similar lever on the opposite side of the machine so as to move in unison with it and by moving the spindles 20 effect equal movements of the flaps. The other arm 26 of the bell-crank lever is connected to a rod 27 acted upon by a compression spring in a cylinder 29, and the arm 26 is set at such an angle that the movement of the spring decreases as it is compressed by upward movement of the flap. Where the trailing marginal flap on each wing is divided into two parts, as shown at 36. 120, Fig. 5, only the outer parts 36 are movable by the pilot to act as ailerons, the inner flap 120 on each side of the machine being connected to the arm 138 of a three-armed lever, the other arms 119 of which are connected by links 39 to the ends of the levers 19. Specifications 15920/13 and 17034/13 also are referred to.

Title: Improvements in or relating to artificial limbs
IPC: A61F2/60
Filed: 1958-07-09
Abstract: A shell or casing for an artificial limb is made from a number of overlapped layers of woven glass fabric, each coated with polyester resin.  A former, made of wood in sections to allow easy removal, is given a first coating of suitable liquid, to prevent the resin adhering to it, and is then given a coating of resin. The first layer of glass fabric is then wrapped around the former with its ends overlapping.  This is covered with a further application of resin and another layer of fabric, and this is repeated until the desired thickness has been built up.  The overlapped portions of different layers are spaced from each other around the former to assist in maintaining a uniform thickness and, to give added strength, the threads of each layer are placed at an angle to those of adjacent layers.  Extra thickness may be built up at the ends of the shell to provide the strength required for the attachment of any necessary fittings.ALSO:A shell or casing for an artificial limb comprises a number of layers of woven glass fabric, each coated with polyester resin.
