Title: Improvements in outer casings for balls
IPC: A63B41/08
Filed: 1932-05-17
Abstract: 402,398. Balls for games. SUTTLE, F., 3, Fitzroy Street, Cambridge. May 17, 1932, Nos. 14011 and 16312. [Class 132 (ii).] In a method of constructing a ball casing such as the casing of a beach ball, of lenticular segments seamed together and provided with an insertion aperture, a finishing aperture is provided in a seam, preferably opposite the insertion aperture, to facilitate the seaming together of the segments, after the seaming of which the portions of the segments adjacent the finishing aperture are drawn through the insertion aperture and the edges of such portions are seamed together to close the finishing aperture. As shown in Fig. 2, the case is formed of sections of rubberised fabric with an insertion aperture 32 in the form of a slot, and the portions of the case adjacent the finishing aperture 30 are drawn through the insertion aperture as shown and the finishing aperture is then closed by stitching, the stitches being arranged to simulate the rows of stitches joining the segments. In the form shown in Fig. 3 the insertion aperture 10 is of circular form reinforced inside by a semicircular sheet. A semi-circular cover 15 of rubber unattached at the straight edge 16 is secured outside the casing. In a further modification, Fig. 6, the insertion slit 18 is inclined and the cover consists of two overlapping semi-circular pieces 22, 23. In a modification, Fig. 11, a positioning flap 47 is secured beneath the insertion aperture and the free portion of the flap is provided with a hole 49 for the inflation tube of the bladder. A tongue 8 is provided for sealing the insertion aperture, and a carrying loop may be secured between two adjacent panels.

Title: A method for casting metallic articles with covered passageways
IPC: B22C9/00
Filed: 1955-05-16
Abstract: 778,005. Core-materials. HILLS-McCANNA CO. May 16, 1955 [Jan. 10, 1955], No. 14063/55. Drawings to Specification. Class 83 (1). Class cores, which are chemically removed from the casting, have an outer layer of a substance which is non-volatile and which is effectively inert to the casting-metal at the casting temperatures. The core is preferably of borosilicate glass. The coating may be of oxides, fluorides or salts of metals, e.g. titanium dioxide, barium oxide, barium fluoride, borium titanate, lead oxide, lead fluoride, lead tungstate, basic lead sulphate, lead chromate, lead metaborate, bismuth trioxide, zirconium dioxide, chromic oxide, ferric oxide, and applied by dipping, spraying, dusting, painting, and sooting, mixed if required with a volatilecarrier such as a low-boiling alcohol which, after application of the mix, may be driven off by heating. Alternatively metallic coatings which are the same as, or inert to reaction with the cast metal, e.g. magnesium, aluminium and alloys thereof, may be used and applied by spraying, painting, dusting or plating. To enable the complete removal of the glass core, after casting, to be verified by radiography, a coating may be selected to be of high radiographic-density with respect to the casting- metal and the glass core. Some of the materials may react with the cast-metal and such coatings, after application to the core, are coated with an inert coating-material. In a modification, radioactive-material, e.g. a radioactive isotope of zirconium, is mixed with the coating- material, e.g. a suspension of titanium dioxide in ethyl alcohol, or the radioactive-material is applied to the core and then coated with an inert material. Removal of all core and coating- material is then ensured when the radiation count measured from the outer surface of the casting reaches a prescribed minimum. The core may be removed by hydrofluoric acid pumped therethrough.

Title: Gyromagnetic Resonance Apparatus
IPC: G01R33/46
Filed: 1967-03-28
Abstract: 1,177,180. Gyromagnetic resonance spectrometers. NIHON DENSHI K.K. March 28, 1967 [March 28, 1966J, No.14167/67. Heading G1N. In a gyro-magnetic resonance spectrometer suitable for measuring large chemical shifts of F<SP>19</SP> nuclei, the range through which the magnetic field can be swept is increased by changing the strength of the polarizing field in discrete steps whereby the sum of the polarizing field and sweep field sweeps across a range of intensity larger than the range of the sweep field. As shown in Fig.l, a test sample 1 containing e.g. F<SP>19</SP> nuclei and a control sample 2 containing protons are both subjected to a common polarizing field from an electromagnet 3. An r.f. transmitter 7 supplies a 60 Mc/s field to sample 2 via coil 37 and also supplies, in conjunction with a 3.554 Mc/ s transmitter 8 and a mixer 6, a 56-446 Mc/s field to sample 1 via coil 4. An audio frequency oscillator 10 supplies a 2 kc/s modulation field to both samples. The gyromagnetic resonance signals of the test sample 1 are detected using the sideband resonance technique described in Specification 1,143,828. The gyro-magnetic resonance signals of the control sample 2 are used to provide field/ frequency stabilization. The output of the sweep source 30, which is synchronized with the recorder 21, is applied to coil 12 to provide the sweep field to both samples and a coil 34 cancels the sweep field applied to the control sample 2. A control unit 39, responsive to synchronizing signals from the sweep source 30, controls the excitation source 35 of the electromagnet whereby in use the polarizing field is stepped up (or down) when the sweep field reaches its highest (or lowest) value, the sweep field being simultaneously reverted to its lowest (or highest) value. Preferably, the levels of the discrete steps of the polarizing field are separated by #m/γ where cam is the angular frequency of the modulating field and y is the gyro-magnetic ratio of the control sample nuclei.

[Class 3 (ii)] [Also in Groups XV, XVI and XXII] A decorative metal plate made of aluminium, zinc or alloys such as nickel iron has an etched surface exhibiting crystals which have different orientations and by which any light striking the plate is reflected in different directions. The plates may be used as floor, ceiling or wall coverings, small plates may be used to build up advertisement letters, or letters may be cut from large plates. In an example; an aluminium plate is rolled and annealed whereby very small crystals are produced and is then deformed as by stretching to a maximum of 5 per cent. after which it is annealed again and is etched with aqua regia so that new crystals which have a large surface area and have substantially the same size are produced. Fig. 2 shows the crystal formation consequent on an extension of 3 per cent., more than 75 per cent. of the surface being occupied by crystals having a surface of at least 5cm<2>. The etching also forms serrations on the crystals 3 ... 5, the largest faces of the serrations being oppositely inclined whereby different effects are produced when observed from different directions. By employing sources of . light of different colours, the crystals appear as different colours when viewed from different positions.
