Title: Liquid dispensing apparatus
Inventor: LEWIS TERRY
IPC: B67D1/12
Filed: 1993-06-29
Abstract: A liquid dispensing apparatus to allow continuous dispensing of beer comprises two beer kegs or reservoirs 10A, 10B connected to a source of compressed gas, each keg having a connection 12A, 12B with a beer line leading to detecting means 14A, 14B incorporating float valves 17A, 17B which act to shut off the line when gas is detected for instance when a keg becomes empty. Upstream of these detecting means 14A, 14B is a switching means 16 which acts to switch the connection between a first keg and the main beer line to the second keg in response to the partial vacuum produced when the float valve of the first keg shuts off the line in response to the emptying of the keg. Priming valves 15A, 15B are provided to remove gas from the system when a new keg is fitted. <IMAGE>

Title: Closure devices with compressible core seal
Inventor: VICTORY MALCOLM GORDON
IPC: B65D39/12
Filed: 1993-08-04
Abstract: A closure device for a bottle or other container includes a compressible core seal 12 within or adjacent the cap 10 such that under axial pressure applied by the cap 10 through a central shaft 23, the core seal 12 expands radially to form a seal within the container neck or outlet. As shown, the seal 12 initially exerts axial pressure on the cap away from itself but when closed, passes a biassing position and then provides tension in the opposite direction to maintain the closure. Alternatively (see Figures 1, 15), the cap 10 may include means to engage the bottle and the core seal 12 is only able to exert pressure so as to push the cap away. The central shaft may be hollow to form a nozzle 73. In this case a valve plate 74 is provided with slots 75 radially outwards of the nozzle such that when in the closed position, the central shaft 23 engages the valve plate 74 to effect a seal. <IMAGE>

Patent GB-2270775-A (GB)
Title: An improved helmet mounted display
Inventor: ANSLEY DAVID A
IPC: G02B27/01
Filed: 1993-09-16
Abstract: The helmet mounted display includes a laser and a fiber optic cable having an array having two sets of rows of optical fibers and mounted to receive input from the laser at an input end and to illuminate a screen with light from the laser via an output end. A first mechanism at the input end of the fiber optic cable illuminates a first set of rows of fibers in the array with light from the laser during a first scanning interval (even frame) and illuminates a second set of rows of fibers in the array with light from the laser during a second scanning interval (odd frame). A second tilting mechanism is mounted at the output end of the fiber optic cable for directing illumination from the first set of rows of fibers in the array to a screen during the first scanning interval and for directing illumination from the second set of rows of fibers in the array to the screen during the second scanning interval. An actuator is provided for moving the first and second tilting mechanisms synchronously and in a specific implementation, the first and second tilting mechanisms are glass plates and the actuator is a piezo-electric transducer. By repeating a scan over a second set of fibers and increasing the pixel intensity at the dead spot location, the visibility of dead spots in the output image from broken fibers is mitigated. <IMAGE>
