Title: Cutting device
Inventor: BRAMHILL JOHN
IPC: B26B27/00
Filed: 1989-08-11
Abstract: The device is intended to be used hold in the hand, e.g. for opening sealed plastics bags. and includes a unitary moulded plastics body 1 which is in the shape of a flat strip formed into a U to provide a pair of arms 2, 3 with grip surfaces 23, 24, joined together at one end. The free end of the arm 2 carries a blade 7 having a crescent moon shaped cutting edge (10, Fig 2) which is directed towards a shallow peak 9 formed by abutment surfaces 8a, 8b on the other arm 3. The blade 7 is mounted on a pin (20, Fig 3) formed on a retaining member 12 which is secured to the free end of arm 2 by snap engagement and preferably also by bonding. e.g. by ultrasonic welding. There is normally a gap between the blade 7 and the peak 9, but the arms can be pinched together between thumb and forefinger against inherent resilience of the body 1 to urge the blade into cutting engagement with e.g. the edge region of plastics package supported on the abutment surfaces 8a, 8b. <IMAGE>

Title: Determining the concentration of a cross-linking agent containing zirconium
Inventor: CHAKRABARTI SUMANA
IPC: C09K8/68
Filed: 1989-10-12
Abstract: The concentration of the agent in a gel is determined by adding an acid to break the gel and convert the zirconium into ionic form. This is followed by the addition of Arsenzo (III) to produce a complex whose intensity may be compared with that of a standard 5. Determination is especially used to control viscosities of fluids used in fracturing oil or gas wells.

Title: Balancing arrangement for rotating member and method of making same
Inventor: OETIKER HANS
IPC: F16F15/34
Filed: 1990-11-14
Abstract: A balancing arrangement for a rotating member (60), especially for a hollow shaft made from light-weight metal, comprises a counterweight (40) of predetermined size and weight which is affixed onto the external surface of the rotating member in predetermined position by the use of a clamping band (10) made from a material normally devoid of any significant elastic stretchability. Elastic stretchability is imparted to the clamping band by specially configured sections (20) which may be formed by openings or non-rectilinear lateral band portions which become less non-rectilinear in the presence of tensional forces in the band and which elastically return to a more non-linear shape when the tensional forces disappear. The internal surfaces of the counterweight and/or of the clamping band are provided with anchoring means to assure position retention thereof on the external surface of the rotating member, and the weight of the anchoring means is in effect additive to the weight of the counterweight. <IMAGE>

Title: Method of and apparatus for making a tobacco stream with a core containing tobacco ribs
Inventor: HEITMANN UWE
IPC: A24B3/16
Filed: 1990-11-26
Abstract: Smaller and larger fragments of tobacco ribs 13 are sifted out of a mixture of tobacco ribs and tobacco shreds before the shreds 12a are converted into a rod-like filler which is ready to be draped into a web of cigarette paper. The larger ribs are comminuted and are mixed with smaller ribs prior to readmission into the flow of shreds in such a way that the readmitted ribs 13a in conduit 44 are located in the inner portion of the rod-like filler so that they are less likely to puncture the wrapper and that they contribute to hardness of the filler. <IMAGE>

Abstract: A bolt (2) comprises a transversely-elongate head (5) for blind insertion through elongate apertures (13) in a pair of members (14, 15), the bolt (2) carrying a sleeve (3) slidable along the bolt (2) but prevented from rotating on it, the sleeve (3) having dogs (12) which engage in the aperture (13). The sleeve (3) has flats (11) which engage flats (9) on the bolt (2) to prevent relative rotation. The flats (9) may instead extend from the head (5) and be angularly offset from the elongations (6) of the head (5). The apertures (13) may be circular with outward extensions or with inward incursions. Alternatively, the sleeve (3) may be omitted, and the bolt prevented from rotating in the apertures (13) by providing pips on the elongations (6) or forming the bolt with an octagonal section. <IMAGE>

Title: Cleaning apparatus and valves for use therewith
Inventor: ELLIOTT RONALD
IPC: B08B3/08
Filed: 1991-01-30
Abstract: Cleaning apparatus for spray guns comprises a generally frusto conical chamber 1 whose upper end is closed by a lid 23. The chamber 1 is preferably supported within the open upper end of an inverted frustoconical base 2 and includes a manifold 4 which is supported by the converging walls of the chamber 1 at a location intermediate the upper and lower extents thereof. The manifold 4 is connected to a source of fluid solvent which is discharged as discrete jets through nozzles formed in the manifold surface. A valve 40, Fig 7 which may be used to operate the primary cleaning cycle (eg using pump 10) is described. A piston 54 forced to the right by pressurized air against a spring 62 to allow communication between passageways 64, 65 to initiate the pump 10 is returned slowly to the left by fluid returning from a reservoir 42 via a restricted passageway 46. An extractor conduit 25 removes solvent fumes. <IMAGE>
Patent GB-2255405-A (GB)
Title: Atmospheric liquid contact sensor
Inventor: HARDEN GRAHAM JAMES
IPC: G01N21/43
Filed: 1991-05-03
Abstract: A liquid content sensor has a length of sheathed optical fibre (11) with a modulated (preferably pulsed) light source (10) at a first end and a light intensity measuring device (13) at a second end. The optical fibre has a length (30) bared for exposure to an atmosphere, and impingement of liquid droplets (17) thereon causes a reduction in passage of light through the fibre (14) (provided that the refractive index of the fibre is not greater than that of the liquid). The reduction in transmitted light is compared with a calibration. <IMAGE>

Title: Gasket size control
Inventor: MARKS KEVIN TREVOR
IPC: F16J15/12
Filed: 1991-07-23
Abstract: The size of the spiral gaskets (G) which are formed by winding a sealing strip (S) and a compressible filler strip (F) around a mandrel (10) is controlled by measuring the angle through which the mandrel (10) turns, e.g., by means of an encoder (14). The lengths of arcs on the periphery of the gasket (G) as it is wound around the mandrel (10) are also measured, e.g., by means of a wheel (46) running on the periphery of the gasket (G) and an encoder (50) counting turns of the wheel. The arcs are defined by the angles through which the mandrel (10) turns. The supply of strip (F and S) is terminated, e.g., by cutting the strips, as result of an arc achieving a particular length.

Building apparatus comprises two or more such members 10 which are adjustable to desired orientations enabling a line or cord to be run therebetween to act as a guide for bricklaying. The elongate member may also be used to support a high-jump or pole-vault bar. <IMAGE>

Title: Seal for gutter
Inventor: STANIFORTH GRAEME
IPC: E04D13/068
Filed: 1991-11-21
Abstract: A joint between a gutter fitting 2 and a gutter 4 is sealed by means of a resilient sealing strip 6 and a groove in the gutter fitting 2. The sealing strip 6 projects by a greater amount in an intermediate portion of the groove than in the end portions of the groove. The gutter fitting comprises two clips 12, which engage respective edges of the gutter portion 4; thus compression of the sealing strip is greatest at the intermediate portion. The seal can also be used between two gutter fillings. <IMAGE>

Title: Apparatus for use in testing the surroundings of a buried pipe
Inventor: ASHWORTH ROGER PHILIP
IPC: G01M7/00
Filed: 1992-04-16
Abstract: The apparatus 10 consists of a pig or pigs in train, which is pulled or propelled through a buried gas, oil, water, chemical or other pipe. The chassis 16 of the pig supports a spring system 32 which carry a mass 30 forming part of an electrodynamic vibrator 31 having an armature driven by alternating current. The armature output shaft 34 is secured to the chassis 16. The mass 30 vibrates, vertically and imposes a force on the pipe. The frequency spectrum of the applied acceleration is measured using an accelerometer 50 attached to the mass 30. The frequency spectrum of the response of the pipe is measured using an accelerometer 54 attached to the chassis 16. Pipe inertance is calculated as the quotient of pipe acceleration divided by the applied force. This is characteristic of the surroundings of the pipe and changes as different surroundings are encountered by the pig as it travels through the pipe. <IMAGE>
