Title: A mobile floor grinding vehicle
Inventor: BECKETT JAMES LEONARD
IPC: B24B7/18
Filed: 1993-02-22
Abstract: A mobile floor grinding vehicle for grinding a floor to a predetermined level and provided with one or more grinding heads which can be continuously adjusted as the vehicle is moved over a floor to maintain the grinding surface of the heads at a fixed position corresponding to the contour to be ground in the floor. Positional control of the heads is effected either by a laser beam from a laser source positioned remote from the vehicle and providing a datum level against which the operative position of the grinding heads is continuously monitored and adjusted using laser beam responsive sensors or by means of signals generated by an on-board computer which vary in accordance with the initial contours of the floor measured against its desired contours and pre-programmed into the computer.

Patent GB-2268011-A (GB)
Title: Residual current device
Inventor: WARD PATRICK
IPC: H02H3/33
Filed: 1993-06-17
Abstract: A residual current device disconnects SCR1, SOL, S1 a mains supply in response to an earth fault current sensed by winding T1 exceeding a pre-determined reference level. An output 81 is indicative of the level of earth fault current and may be connected to a meter or provide a visual warning at a reference level lower than that at which the device trips. The device draws power from the live L and neutral N lines but may alternatively use the earth E line if there is a loss of neutral and warn with LED1. Impedance Z1 prevents the use of the earth path except when neutral is lost. Two test windings T2, T3 connected in antiphase between neutral and earth, with the mid-point connected to live or to a reference voltage, detect a potential difference between neutral and earth lines, and disconnect the supply. Capacitor C1 charges sufficiently to activate the solenoid on firing of SCR1. On Cf charging to the reference voltage level required for disconnection, the fault current must persist for a further fixed time delay determined by Rt Ct before the supply is disconnected. <IMAGE>

Title: Golf club swing training device and method
Inventor: RADAKOVICH DANIEL L
IPC: A63B69/36
Filed: 1993-09-17
Abstract: A device for facilitating correct swinging of a golf club (12) comprises an elastic loop (22) which is donned over the head of the player (10) with the major portion of the loop resting over the chest, abdomen, and on top of the shoulders. The rear (28) of the loop (22) is affixed to the body of the player (10) so that the loop (22) is disposed away from the neck, approximately at the height of the third vertebrae of the back (spine). In play, the handle end (14) of the club is laid inside the front end (20) of the elastic loop (22) and pushed downward and outward by the left hand and arm (16) stretching the loop (22) as much as possible. Swinging the golf club (12) against the upward pull exerted by the eleastic loop (22) produces the surprising effect of improved control of the golfers arms which results in a nearly perfect swing plane and levelling and squaring up of the golf club face. <IMAGE>

Title: Radio direction finder and beacon
Inventor: ROBINSON STEPHEN JOSEPH
IPC: G01S3/10
Filed: 1996-02-01
Abstract: Ground plane referenced triplet receiving or transmitting antenna arrays (figure 2), are used to measure the direction of propagation of radio signals. The arrays may be optimised for high accuracy and high integrity elevation measurements over selected angular sectors, notably at low angles in the presence of ground reflections. Various receiving arrangements may be embodied in equipment compatible with transmitting, reflecting and transponder based systems; and may be used with identity and range information therefrom, to determine the height of objects. A particular array is described, and included in a system (figure 6), for monitoring the height of aircraft near to airfields. This system may "stand alone" or be fully integrated with standard secondary surveillance radar equipment in the "Airfield Management" or wider "Air Traffic Control" system. A transmitting arrangement is also described which will reduce the cost of standard I.L.S. glidepath installations.

Title: Process for the purification of a gas by scrubbing-venturi column for carrying out said process
Inventor: MELINE FRANCOIS
IPC: B01D49/00
Filed: 1994-09-09
Abstract: Method for the clearing of a gas (G) contaminated with liquid and/or solid particles using a venturi column with a vertical axis. The method consists in: pneumatically spraying the throat (3) of the venturi device with a scrubbing liquid in an ascending stream of said gas, the scrubbing liquid being injected in a direction substantially perpendicular to that of said stream; eliminating, downstream of said throat, the scrubbing liquid vesicles carried by the gaseous stream and laden with contaminants. The method is characterized in that a sonic field is generated in the region of the venturi throat (3) to force shifting of the contaminating particles in relation to the scrubbing liquid vesicles. The present invention also concerns a venturi column for carrying out said method. <IMAGE>

Patent GB-2312311-A (GB)
Title: An alarm device having a long-life power supply
Inventor: BYRNE MICHAEL
IPC: G08B29/18
Filed: 1996-07-17
Abstract: An alarm device (1) has a power supply compartment (20) with a chamber (40) which prevents access to long-life Lithium batteries (26). To activate the control circuit, the user presses a push-button (53) which causes a sloping surface (54) to push a sliding switch member (71) to the left. This action is not reversible by virtue of construction of the interface (52) having the push button (53) which covers the switch (70). For de-activation, the user simply cuts an exposed lead (28). Again, this is simple and not reversible. This allows the alarm device to be distributed and stored at a retailer without being activated and therefore prevents nuisance alarms arising before sale. It also maximises the useful life for the user. By allowing de-activation, low-battery sound emissions are avoided at the end of the useful life of the alarm device.

A loading member (36, 208) is pivotally joined to the support frame (54; 216A, 216B) at a position spaced apart from the wheel adapter housing (16, 206). A plurality of spaced apart struts (32A, 32B, 32C; 202A, 202B, 202C) connects the loading member (36, 208) to the wheel adapter housing (16, 206). An actuator (62, 204) applies a selected force to the loading member (36, 208) to apply a lateral force to the vehicle spindle (12). In a first embodiment, an adjustable coupling (65, 284) connects the actuator (62, 204) to the loading member (36, 208) to emulate a rolling radius of a tire assembly mounted to the vehicle spindle (12). In a second embodiment, a second loading member (44, 214) is operably connected to the first-memtioned loading member (36, 208). A second actuator (80, 218) applies a force to the second loading member (44, 214) to apply a selected moment to the vehicle spindle (16).
