Patent ZA-861755-B (ZA)
Title: Stable nitrate/slurry explosives
Inventor: HONEYMAN GORDON RUSSELL
IPC: C06B47/14
Filed: 1986-03-10
Abstract: Explosives that are sensitized blends of inorganic nitrate. e.g., AN, particles, such as AN or ANFO prills, and an aqueous slurry comprising a thickened aqueous solution of an inorganic oxidizing salt, preferably AN, are rendered storage-stable by keeping the slurry's water content low enough, and its viscosity high enough, that the slurry is water-retentive. Water immobilization in the slurry, a requirement for storage stability, is achieved despite the slurry's flowable consistency at the time of blending. A blend containing about 25% slurry or less, is essentially in the form of a granular mass of free-flowing, high-density, slurry-bearing prills, and the slurry is sensitizable by the prills alone. As the slurry content exceeds about 25%, the blend takes on the characteristics of a thick slurry, requiring a supplemental sensitizer in the slurry perse. Slurries containing a nitrogen-base salt of an inorganic oxidizing acid, preferably monomethylamine nitrate, are preferred because this additive affords a saturated solution with lower water content, and also can act as a sensitizer.

Title: Radio frequency heating
Inventor: PERKIN ROBERT MELSON
IPC: A23B4/07
Filed: 2009-06-16
Granted: 2013-12-04
Abstract: To enable a practical RF oven to heat a wide range of product volumes for different operations such as baking or defrosting, an auxiliary removable box shaped metal electrode 8 is inserted underneath the product 3 to be processed. This electrode has a cross-sectional area comparable to that of the product to be heated and a height which minimizes any air gap above the product, subject to processing requirements. A polymer holder 13 (fig 6) may hold an appropriate number of auxiliary electrodes 8,8' so as to match the area of the product(s)3,3'. A polymer enclosure 5 separates the main electrodes 1,2 from the product chamber. Alternatively the auxiliary metal electrode may be replaced by a dielectric with a large dielectric constant of 100 or greater, for example the auxiliary electrode may comprise a polymer container 19 having modules filed with water 21. Fig 7 not shown discloses the use of ice added to the top of a product to reduce the gap under the electrode 1 and to promote uniform heating.

Title: Releasable and adjustable end attachment for watchband and the like
IPC: G04B37/16
Filed: 1979-11-06
Granted: 1982-09-22
Abstract: Disclosed is a watch band end attachment adapted to be releasably and adjustably mounted between the spaced lugs of a watch. The end attachment of the invention typically includes a housing, one end of which fits between the spaced lugs and the other end of which is connected to the watch band, and levers on opposite sides of the housing with a sliding member therebetween. The levers have lug-engaging ends disposed in the first end portion of the housing and pivot ends in the second end portion. Cam surfaces of the levers coact with cam-engaging surfaces of the sliding member as the latter is translated from the pivotal ends toward the lug-engaging ends of the levers to cause the lug-engaging ends to pivot and extend through the side apertures in the housing and engage the lugs of the watch. Reverse movement of the sliding member disengages the end attachment from the watch. Accidental disengagement is prevented by locking means typically in the form of a spring associated with the levers or sliding member. Attachment and detachment is accomplished by simple manipulation of a finger tab connected to the sliding member and accessible from outside the housing.

Abstract: A threaded bore in a flange (4) of a reactor pressure vessel (1) can be plugged or sealed by means of a sealing or plugging element (6) and a tool (8) with the reactor pressure vessel cover (2) in place. In order to obtain a tight seal, the plugging element (6) is joined in a detachable manner to the tool (8) and has a shoulder (11) thereof set down on the upper face (4a) of the flange (4). An O-ring (15) borne by the plugging element (6) is compressed between two relatively movable parts 12, 13 of the tool and is thereby pressed radially outwardly against the peripheral surface of a free turn (7) of the threaded bore. The relative movement of the two parts 12, 13 is effected by rotation of a nut 20. <IMAGE>

Title: Apparatus for the cleaning of teeth
Inventor: MAURER WILHELM
IPC: A46B9/04
Filed: 1985-08-15
Granted: 1988-11-09
Abstract: A tooth cleaning device for optimal tooth cleaning comprises, on a U-shaped carrier (109), tufts of bristles (180), which are placed against the tooth using pressure bubbles (149) under equal cleaning pressure on both sides. With this arrangement the tufts of bristles (180) are fitted to individually self-positioning rocker arms (174, 178'), in order to also engage in the spaces between the teeth, which are difficult to access. With the aid of a further pressure bubble arrangement (147) using phase-shifted pulsating pressurization, with reference to the pressure-generating bubbles (149), a wiping movement of the tufts of bristles (180) with cleaning pressure is generated in the direction from the gum towards the crown of the tooth, in counter-direction without bearing pressure on the tooth.

Title: Improved liquid dispensing arrangement
Inventor: MORGAN PHILLIP
IPC: B67D1/12
Filed: 1987-07-01
Granted: 1989-12-13
Abstract: A beer dispensing arrangement comprises electronic control circuitry (56) having in circuit reed switches (42) and a Hall effect sensor (54), the circuitry (56) also having in circuit a beer pump (24) for moving beer from a supply to dispensing taps (30,32). The reed switches (42) are operated by a magnet in a float (34) while the sensor (54) detects movement of a magnet (52) controlled by a pressure sensitive diaphragm (48). During dispense, with the float (34) being sensed in its uppermost position, the sensor (54) reacts to the pressure in the line and the control circuitry (56) operates by way of the sensor (54) to automatically control the pump (24) and maintain pressure in the line at a desired operating level. Regardless therefore of the condition of either tap (30,32), the arrangement provides a substantially constant rate of dispense.

Abstract: A base structure for a mobile access platform includes a chassis (10) having at least two pairs of wheels (12, 16), at least a first one of said pairs of wheels (16) including a suspension mechanism including, for each wheel, a swing arm member (18) on which the wheel is mounted, said swing arm member (18) being arranged to pivot about a substantially horizontal pivot axis (20), a stop member (22) arranged to engage the swing arm member (18) so as to limit upwards movement thereof, and biassing means (24) arranged exert a biassing force on the swing arm member (18) to urge the swing arm member upwards towards the stop member (22). The biassing force is less than the force needed to maintain the swing arm member (18) in engagement with the stop member (22) when the wheel is unsupported. The arrangement is such that the swing arm members (18) normally engage the stop members (22) when the mobile access platform is standing on flat, level ground. <IMAGE>
