Patent GB-2017514-A (GB)
Title: Fluid Mixing Devices
IPC: B01F15/02
Filed: 1979-03-19
Abstract: A main flow passage 18 is divided into two subsidiary passages 19, 19a downstream of a low pressure zone 26, and is formed in a valve member 17 which is rotatable to prevent flow of fluid through at least one of said subsidiary passages, when required, thereby reducing the effective cross-sectional area of the main flow passage and creating back pressure which fills the low pressure zone and renders it ineffective in drawing detergent into the low pressure zone through an auxiliary passage 30. <IMAGE>

Title: Improved dispenser closure
IPC: B65D47/20
Filed: 1979-09-24
Abstract: A closure member 25 comprises a skirt 26, a flange 32 defining a cylinder having a slight inward taper and a wall 31 which has a wedge- shaped cross-section. The member can be fitted to a spout in a fully sealed condition in which ribs 35 of the flange 32 sealingly engage the spout and sealing engagement is maintained against inadvertent breakage of the seal by abutment of skirt flanges 27, 28, respectively with spout ribs 29, 30. Alternatively, Fig. 4 (not shown), the member can be fitted in a dust cap position in which the lower extremity of flange 32 beneath ribs 35 makes a light friction fit in the spout with flange 27 abutting ridge 30. Manipulation of knob 33 to deform the wall 31 as shown in dashed lines in the figure allows dispensing of the contents. The closure enables a reliable seal to be effected which is not inadvertently broken by knocking or stacking but which can readily be broken when it is desired to dispense container contents. <IMAGE>

Title: Synthetic resin thin-walled bottle
IPC: B65D1/02
Filed: 1979-12-14
Abstract: Bottles for containing carbonated drinks are made from synthetic resin and provided with thin walls.

Title: Dispensing or Evacuating Device
IPC: A47K5/122
Filed: 1980-08-22
Abstract: A tubular dispenser for semi-liquid or pasty material such as toothpaste comprises a flexible elastic tube 1 closed at opposite ends by a nozzle member 2 and a perforated plug 6. Within the tube 1 is a ball 5 of diameter slightly greater than the tube 1 so that it is gripped by the walls of the tube 1. The ball 5 is moved towards the nozzle 2 by manually squeezing the tube 1 adjacent the ball 5 thus expelling the tube contents 4 from the tube 1. As an alternative embodiment, in an evacuator the ball is manipulated towards the plug so that liquids can be sucked into the tube through the nozzle. <IMAGE>
Patent GB-2060841-A (GB)
Title: Improvements in or relating to steam boilers
IPC: F22B31/00
Filed: 1980-09-29
Abstract: In a boiler in which at least one water drum 30 is connected to a steam drum 32 by tubes 34, 42, 44, 46, 54 which are heated by combustion gases provided by a fluidised bed 36, the furnace zone of the boiler is divided into a primary furnace zone 38 and secondary furnace zone(s) 40. The secondary furnace zone is situated above the primary furnace zone 38 and partially separated therefrom by tubes 42 which form a roof above the primary zone 38. The combustion gases can only leave the zone 38 in a vertical direction and without any significant increase in vertical velocity. Upon entering the secondary furnace zones 40, the gases are allowed to move in a horizontal direction. These features restricting the movement of the gases help to prevent migration of combustion material to other parts of the boiler. This is of particular importance in a boiler which uses the fluidised bed combustion process. <IMAGE>

Patent GB-2069780-A (GB)
Title: Battery charger
IPC: H01M10/44
Filed: 1981-01-12
Abstract: A battery charger, particularly suitable for NiCd batteries, supplies pulses of charging current to at least one battery connected to terminals 9-14, and discharges the battery between each charging pulse. The change in the battery terminal voltage over a predetermined period during each charging pulse is measured by voltage sampling circuitry connected to terminals 25-31, and the pulse charging is terminated when a parameter of the measured voltage change exhibits a predetermined characteristic. Pulse charging may be terminated as a result of the measured voltage change exceeding a predetermined threshold or as a result of the detection of a point of inflexion in the variation of measured voltage change with time. The charge-discharge cycle is controlled by switching transistors 16-19. LED's 21, 22, 40, 41 indicate progress and completion of charging. The charging current may be modified in dependence on internal battery temperature, and a microprocessor is used for overall control. <IMAGE>

Title: Apparatus and method for tagging tube
IPC: B21D15/02
Filed: 1981-09-24
Abstract: A method and apparatus are described for cold-roll tagging of tube prior to cold drawing. The method can be carried out on previously phosphated tube stock (14) and comprises feeding the stock between rolls (10, 11) provided with grooves (19, 20) and pinching the stock in a plane perpendicular to the roll axes to produce a dog-bone cross-section (Fig. 9). A second pass, with the stock (14) rotated at 90 DEG , through further grooves (21, 22), compresses the dog-bone cross-section to a folded small diameter generally circular cross-section tag (Fig. 10). The rolls rotate in a sense opposite to the initial stock feed direction, to simultaneously rollform and return the stock from the nip of the rolls. The rolls may in practice be only sectors of full rolls. <IMAGE>
Patent GB-2089185-A (GB)
Title: Improvements in and relating to liquid applicators
IPC: A01M21/04
Filed: 1981-11-24
Abstract: An applicator for applying liquids to plants comprises an elongate tubular handle (10) with transverse foot (12) at one end, the interior of the foot being in fluid communication with the interior of the handle. A length of water absorbent material (18), e.g. rope, extends around the exterior of the foot and passes in a sealing manner to the interior. A container (20) of liquid to be applied is attached to the other end of the handle, e.g. by screw threaded connection. Upon such attachment an apertured piercing member of the handle punctures a closure member of the container, permitting liquid to pass from the container to the interior of the handle and into the foot. The absorbent material becomes wetted with the liquid, producing a film of liquid which can be applied to plants as desired.   <IMAGE>
