Title: Puzzle assembled from magnetically cooperating pieces
Inventor: BURTON PETER
IPC: A63F9/12
Filed: 2009-08-14
Abstract: A take-apart puzzle comprises a number of bricks 1 which can be assembled to form a predefined structure (figure 1) held together by cooperating hidden magnets 2,3 within the bricks. Upon disassembly of the structure (figure 2) the magnet 5 in at least a first one of the bricks 7 assumes a different position/orientation within the brick such that the magnet will no longer cooperate with at least one of the neighbouring magnets 2 within the assembled structure. Thus, the structure cannot be reassembled until a movement or convoluted series of movements of the first brick 7 relative to at least one other brick 1 repositions the magnet to its cooperating position. Movement of the magnet upon disassembly may be effected by a stored-energy device or additional magnet (not shown) provided within the brick. In a preferred embodiment the bricks are identical, and the assembled structure resembles a house or similar building (figure 1).

[Class 38 (ii).] The supporting member or members 13, 17, 40 of the vanes of a variable condenser are of uniform non-circular cross section such as to provide a jamming surface engaging with cooperating portions of the openings in the vanes by relative rotary movement. As shown, the spindle &c. is of volute cross section and the apertures in the vanes are of similar shape. In assembling, each set of moving vanes is inserted in slots in a cradle mounted so as to move about the spindle as an axis, after it has been passed through the appropriate holes in the vanes. The spindle is held at each end and between the gang-sections and in such a manner that it cannot rotate, and the cradles holding the sets of vanes are rotated, jamming the vanes securely at spaced intervals. The tips of the vanes are similarly held by a volute-section rod 40, rotated in the vanes by a shaped tool. The fixed vanes are mounted on the rods 13 by assembling in jigs together with supporting brackets 14 and locked by rotation of the rods by a shaped tool. In a modified arrangement all the vanes both fixed and moving are assembled together in a jig in the spaced relationships they will ultimately occupy in order to ensure uniform spacing between neighbouring plates. A locking strip may be inserted in the space on the rod or spindle vacated by the jamming movement.

Title: An improved method of producing a tapered fishing line
IPC: B29C48/05
Filed: 1969-02-27
Abstract: 1,211,963. Fishing line. SOO VALLEY CO. Inc. 27 Feb., 1969 [15 Nov., 1968], No. 10615/69. Heading A1A. [Also in Divisions B2, B5 and D1] A tapered fishing line is produced by (a) centering in the extrusion orifice of a coating die and drawing through the orifice a continuous flexible filamentous core of uniform diameter, (b) extruding through the orifice at a constant volumetric rate a fused thermoplastic synthetic polymeric material which forms a layer that surrounds and is bonded to the core, the polymeric material having a 'torsional stiffness' of 2,500 to 12,000 p.s.i. (determined by ASTM test method No. D1043-61T) and the core having less stretchability than the coated core from the extrusion orifice in a positive manner at a maximum speed such that the diameter of the coated core is at a minimum, (d) gradually decreasing the speed at which the coated core is withdrawn to draw the core through the orifice at a decreasing speed and to increase the diameter of the coated core, (e) after the coated core issuing from the orifice has attained a predetermined maximum diameter, gradually increasing the speed at which the coated core is withdrawn until the coated core has attained its maximum speed and its minimum diameter, repeating steps (d) and (e) as often as desired, and (f) severing the coated core at the points at which such minimum diameter was attained to produce individual fishing lines each of which tapers at both ends to a tip of such minimum diameter. The coating layer may consist essentially of a polyvinyl plastisol. The coated core upon leaving the extrusion orifice may be heated to further fuse it and then allowed to cool so that the coating layer solidifies and becomes bonded to the core. The core may be a single filament or a multiplicity of filaments which may be parallel, twisted or braided. The core may consist of nylon, "Dacron" (Registered Trade Mark) or natural silk. A primer is preferably applied to the core before it is coated to improve the adhesion of the coating to the core. The primer may consist of a solution of any synthetic resin that is compatible with the coating material. Thus it may consist of a solution of a copolymer of vinyl chloride and vinyl acetate in methyl isobutyl ketone, or of a solution of an acrylonitrile-butadiene copolymer in methyl ethyl ketone or in methyl isobutyl ketone. The coating may consist of polyvinyl chloride (and/or a copolymer of polyvinyl chloride and a small proportion of another monomer such as vinyl acetate) plasticized with a conventional plasticizer for polyvinyl chloride, such as di-octyladipate, containing a stabilizer such as a lead soap. The density of the fishing line produced may be reduced by incorporating in the plastic to be used a conventional blowing agent, or may be increased by incorporating microscopic glass beads, lead shot, or lead oxide particles in the plastic. The use of coatings consisting ethylenevinyl acetate copolymers is disclaimed.

Title: Improvements in signalling systems for distributing speech or other sounds to listeners
IPC: H04R3/12
Filed: 1937-04-14
Abstract: 476,022. Distributing music &c. GUIDED RADIO CORPORATION. April 14, 1937, No. 10635. Convention date, April 29, 1936. [Class 40 (iv)] In a system for distributing programmes, announcements, &c. to listeners over a conductive network, the various receivers may be selectively disconnected from or connected to the network by the application of various control currents at the distributing station. The Figure shows a system for ships or buildings employing a grounded network 18, 19, 20 forming part of the structure, e.g. the steel framework, water or gas pipes, or the neutral wire of a three-wire power circuit. Signal currents are fed into the network through an amplifier 4 and condenser 10 from apparatus 3, which may be a wireless receiver, a gramophone pick-up or merely a microphone. The receivers 22, 27, 32, 36, 40, 44, 49, which may be either loudspeakers or complete wireless receiving sets, are connected to earth through a condenser, and each is adapted to be short-circuited by operation of a corresponding relay. Relays 25, 30 are polarized and are operated by direct current of appropriate direction applied over a switch 12. Relays 34, 38, 42 are associated with condensers of different capacities so that they respond to different low frequencies applied from a source 15 when one of the switches 17 is closed. Relays 46, 51 are associated with tuned circuits so that they respond respectively to frequencies generated by oscillators 5, 7 which are controlled by switches 6, 8. The system is therefore capable of use in making announcements to any desired groups of listeners. A relay 97 associated with a tuned circuit 98 is normally energized by current from a source 90 in series with a normally closed switch 92, and a lamp 96 is thus disconnected. Signals can thus be sent by operation of the switch 92, and in the normal state the lamp would light to indicate a break in the circuit. Another system described, Fig. 2 (not shown) employs an ungrounded network, and the receivers are connected up in response to the application of different currents to the network.

IPC: A21D8/04
Abstract: 106,531. Stevenson, J. A. May 25, 1916. Yeast.-Brewers' yeast is freed from acidity and bitterness and is invigorated so that it may be mixed with distillers' or other yeast for breadmaking. The yeast is agitated with water in a vessel 2, acidity is neutralized by sodium carbonate solution from the tank 3, and the liquid is discharged through a strainer e to trap light deleterious solids, and into a receptacle 4 where it is mixed with salt solution from the tank 5 to precipitate tannin, increase the density of the solution, and facilitate settlement of the hop seed and other impurities. The supernatant liquid, with the suspended yeast cells, is run into a vat 6 and treated with formaldehyde and calcium carbonate to precipitate the tannin, decolorize the yeast, and prevent the increase of bacteria; this process is repeated in vat 7, and the supernatant liquid treated in vat 8 with oxygen produced electrically or chemically. The liquid is then mixed directly with other yeast, or is first passed through a filter-press 9. The sodium carbonate solution may be added to the tank 4 instead of the tank 2, or the sodium carbonate, salt, and formaldehyde and calcium carbonate may be added together to the tank 6.
