Title: Hydraulic clamping system
Inventor: AUBREY MARTIN JAMES
IPC: E02F3/36
Filed: 1985-02-23
Abstract: A member (1), having an hydraulically operated piston/cylinder arrangement (6) which includes an enlarged head (3), can be connected to a plate (4) by causing said head to pass through the large portion of a keyhole aperture (5); subsequent movement of the member (1) so as to move the head (3) out of alignment with the large aperture portion followed by actuation of the arrangement (6) such as to bring the head into contact with the plate will result in the plate (4) becoming clamped between the head (3) and the member (1). Hooks (2) on the member (1) and complementary apertures (14,15) in the plate (4) provide anti-rotational stability. The plate (4) may be incorporated in an appliance (e.g. an excavator bucket) and the member 1 may be carried upon one end of the arm- or boom-means of a vehicle, whereby the vehicle driver can mount and demount the appliance without needing to leave the driver's seat. <IMAGE>

Title: Low-cost, full-function container for food, beverages and other products
Inventor: AVERY DONALD J
IPC: B29C51/16
Filed: 1984-09-14
Abstract: A low-cost, full-function container (125) includes a tubular convolute or spiral-wound paperboard or composite material structure (127) that may be of various geometric shape to enclose a thin-walled vessel (131) of material constituting a barrier for enclosing and protecting a product, the structure having sufficient thickness and rigidity for supporting and protecting at least the enclosed sides as well as the bottom of the vessel. The vessel material wall thickness is inadequate for permitting the vessel conventionally to serve alone as a container for the product. A closure (133) for the vessel at its upper end seals the product hermetically or atmospherically with the product being protected from the air, other gases, moisture and light. The vessel may be formed in situ within the structure.

Title: Intra-vaginal contraceptives
Inventor: BRATBY DAVID MICHAEL
IPC: A61K9/00
Filed: 1985-12-04
Abstract: An intra-vaginal ring contraceptive which comprises a central annular core containing a contraceptive hormone and an annular cladding around the core, the core and the cladding being formed of compatible resilient polymeric materials through which the hormone can diffuse, and in which the core further contains a radio opaque material or, where the cladding material is translucent or transparent, a coloured material so that the location of the core within the ring can be determined by visual means or X-rays. The contraceptive screened in this manner is more reliable since those in which the core of hormone is significantly off-centre release hormone considerably faster than normal and can therefore be rejected in a screening process.

Title: Borehole inertial guidance system
Inventor: MOLNAR DANIEL O
IPC: E21B47/022
Filed: 1985-05-31
Abstract: In order to improve the accuracy of borehole survey systems utilizing probes (18) with inertial components including inclinometers (32, 34, 36), two ring laser gyro units (42, 44) are included to provide rotation information to the system. When the probe (18) is moving in a borehole (12), inclinometer information is used to produce a synthetic rotation signal to take the place of a third gyro and the earth's rotation is used for a similar purpose in combination with signals from the two ring laser gyros (42, 44) when the probe (18) is stopped. Wire line velocity is used in combination with the inclinometer and gyro information to provide signals representing the probe velocity and position. Coordinate transformations are provided in the probe to transform the inertial signals and wire line velocity signals into earth reference coordinate system. Kalman filtering incorporates noninertial velocity data to reduce the effect of errors inherent in the generation of various input signals to the system.

Patent GB-2180643-A (GB)
Title: Coal analysis
Inventor: WORMALD MALCOLM RODERIC
IPC: G01T1/36
Filed: 1986-09-15
Abstract: An analysis system for analysing coal or other material causes the material (3) to be bombarded with neutrons (2) from a source (1), and this generates gamma rays (11,12,13) from the material (3) which are detected by a detector (4). The detector has scintillators (5,6) which generate light when a gamma ray is detected, the light being detected by photomultipliers (8,9). Each gamma ray generates two other gamma rays, which may both be wholly absorbed in one or the other scintillator (5,6) or one absorbed in one scintillator and one in the other. By analysing these events, the spectrum of gamma rays may be obtained, giving the composition of the material. One preferred detector has an array of scintillators and coincident gamma ray detection events in three adjacent scintillators detected.
Patent GB-2180911-A (GB)
Title: Coupling
Inventor: MULLER ANTON
IPC: F16G15/06
Filed: 1986-09-26
Abstract: A coupling (1), such as a shackle, clevis or the like, comprises a base member with at least two sides (2,3) spaced apart. They each comprise an insertion opening (7,8) for a suspension bolt (10). The bolt (10) is prevented from falling out of the insertion openings (7,8) by locking members (14,15) disposed transversely to the bolt axis. One locking member (15) projects only partly into one of the two insertion openings (7,8) which have the same diameter. Thus the inside width (16) of the suspension opening (8) is reduced. It is thereby ensured that only the correct size of suspension bolt (10) will be inserted in the coupling (1), the ultimate strength of which bolt (10) is coordinated with the ultimate strength of the chain (11) to be suspended, since a smaller bolt will fall out of the insertion openings. On account of their identical diameter, the two insertion openings (7,8) may be drilled in a simple manner in a single operation, due to which the desired, economical and simple manufacture is achieved for the coupling (1) as a mass-produced product. <IMAGE>
