Title: Motion generating mechanism
IPC: G06K15/22
Filed: 1966-11-11
Abstract: 1,126,947. Linkwork; belt gearing. INTERNATIONAL BUSINESS MACHINES CORP. 11 Nov., 1966 [18 Nov., 1965], No. 50543/66. Headings F2K and F2Q. [Also in Division G1] A motion generating mechanism for an automated drafting machine comprises mechanical actuators operable to generate linear and simple harmonic motion, having predetermined amplitude and phase, along two axes at rightangles, the motions being combined into a resultant at a single point. A platform 44, which may carry a stylus, is mounted slidably on intersecting cross-bars 10, 12 which are mounted on separate pulley and cable arrangements for independent movement along x and y axes. Cross-bar 10 is carried by a belt 14 which is connected by a clamp 60 to a piston adder mechanism 58 which effects movement of the cross-bar 10 in the horizontal direction. Similarly cross-bar 12 is carried by a belt 30 which is connected by a clamp 100 to a piston adder mechanism 98 which effects movement of the cross-bar 12 in the vertical direction. Piston adder mechanisms as described in Specification 1,051,509 may be employed. Clamp 60 is reciprocated by a mechanism comprising a pin 56 adjustably mounted on a wheel 54 and engaging a slot 52 in a member 50 at the lower end of piston adder mechanism 58. Similarly, clamp 100 is reciprocated by a mechanism comprising a pin 96 adjustably mounted on a wheel 94 and engaging a slot 92 in a member 90 at the lower end of piston adder member 98. Rotation of wheels 54, 94 is effected by a toothed belt 124 which is driven by a piston adder mechanism 132. The phase relationship between the wheels 54, 94 may be varied by actuation of piston adder mechanism 134 and bias chamber 136 incorporated in the toothed belt 124. The mechanism may be used to produce straight lines, circles and ellipses.

Title: Rolling of gear locks
IPC: B21H5/02
Filed: 1972-11-03
Abstract: 1386489 Rolling gear teeth LEAR SIEGLER Inc 3 Nov 1972 50809/72 Heading B3M [Also in Division F2] The teeth 14 (Fig. 4B) of a clutch gear are provided with relatively depressed faces 28 separated by shoulders 30a, 30b from relatively prominent faces 26 by rolling the teeth in mesh with the conjugate teeth 38 (Fig. 4A) of a roller die. The clutch gear may be rolled by a single die whose axis is parallel, or nearly parallel, to the gear axis, or may be rolled between a pair of dies. In the latter case both of the dies may have profiled teeth, or one may have plain teeth. Instead of a prominent central face 26, each tooth may have a depressed central face, or may have just two faces separated by a shoulder. The dies may have the central areas 40 missing, or when a central depression is formed in the clutch gear teeth, the outer areas 42 missing. Each die may be of composite construction, in which the areas 40 and 42 are formed by separate dies welded, brazed, or clamped next to one another. The finished clutch gear 13, Fig. 1, co-operates with an axially movable ring gear 20.

Title: Filter assembly for sterilizing water
IPC: C02F1/50
Filed: 1964-12-21
Abstract: <PICT:1063669/C1/1> A portable filter assembly for purifying drinking water comprises a manually operated piston pump 3, 15 and a bacteria removing and purifying filter 21, 22, arranged in a common housing and connected by a passage 5 incorporating a non-return valve 13, the pump connecting by a tube 8 to a source of impure water through another non-return valve 10.  The outlet 31 is threaded to receive a canteen for milling when the pump is operated, and tube 8, when not in use, coils round the housing 1, which is of moulded plastic.  The filter comprises bacteria-removing filter element 21 enclosing a sorbent 22.  Element 21, as shown, is a pleated paper cylinder whose pores are reduced to average less than 0.2 microns by a deposit of particulate material, but sintered, foamed or woven metal, plastics or textiles may be used instead of paper. The particulate material may be any of a comprehensive list of natural or synthetic textiles or plastics, metals, minerals and ion-exchange resins in fibrous and/or granular form, and may also incorporate various slightly soluble silver salts which kill any bacteria deposited on the filter element and remain in non-toxic amount in the effluent water to maintain its sterility. Preferred forms are a mixture of asbestos fibres and 12.5% silver bromide or a mixture of diatomaceous earth and glass fibres, deposited on paper.  The element is prepared by depositing the particulate material on to the supporting surface from a liquid dispersion and an intermediate layer of binding agent may be incorporated. The bactericide may be applied separately or together with the particulate material. The sorbent 22 is preferably activated carbon but other materials listed are chabazite, silica gel, chromic oxide gel, lithopone, powdered porous glass, glass wool, activated alumina, quartz crystals and fuller's earth.  Clogging of the filter is indicated by opening of a relief valve 28 and discharge of water therethrough, but the vent 45 can be closed by the user so that the pump 3, 15 forces water through a partially blocked filter.

Abstract: 1,207,906. Mollusc-dredger. BORDEN Inc. 6 Nov., 1968 [6 Nov., 1967], No. 52519/68. Heading E1F. In a suction dredging apparatus for the harvesting of molluscs and the like the rate of flow of the sucked in suspension through the suction pipe of the dredger is maintained substantially constant irrespective of variation of the ambient pressure adjacent the intake of the pipe by recording the pressure differential between said ambient pressure and pressurised gas entering the pipe at a zone 36 at some distance along the pipe from the lower end thereof to cause lift therethrough and adjusting the pressure of this gas as necessary to maintain the pressure differential constant. The ambient pressure is measured by recording the pressure of a gas flow at a constant flow rate from the pipe 54 terminating adjacent the mouth of the suction pipe 14. This pressure is compared to the gas pressure in a transmitter 61 from which a signal is emitted as is necessary to a controller 64 of a regulator valve V in the gas supply conduit 37 by which pressurised gas is supplied to the zone 36. Associated with the lower end of the suction pipe is a sledge having a scraper blade and a ramp that are pivotably adjustable with respect to the sledge. The position of the ramp relative to the sledge can be indicated by lights 70 on the towing vessel of the apparatus, said lights being connected to limit switches on the sledge. Blockage in the suction pipe can be cleared by shutting off the gas to the zone 36 and applying pressurised gas through a pipe 45 to the also shut off upper end of the pipe.
