Filed: 1993-07-14
Abstract: A wall-mountable anti-theft device for saddles comprises a mounting plate 1 (Fig. 4) having a pair of upstanding lugs 2 supporting a pivot pin (3). A stop plate (6) rests against the mounting plate (1) to hold the bar 4 horizontal, and in this position also protects the heads of the screws or bolts which secure the mounting plate 1 to the wall. A cage 9 comprises a hollow rectangular tube 10 which receives the bar 4 as a sliding fit.

IPC: B65B13/02
Filed: 1993-07-30
Abstract: A gripping and cutting tool for securing tie-wraps comprises an actuator handle 1 and a gripping handle 2 which are pivotally joined together. The free end of a loosely pulled tie-wrap 5 is fed in through hole 11, in handle 1, and out through hole 21 of handle 2.

Title: Drive control apparatus for brushless DC motor and driving method therefor
Inventor: UESUGI MICHIKA
IPC: H02P6/08
Filed: 1994-03-17
Abstract: A switching circuit 4 includes pairs of switching elements Tu<+>, Tu<->, Tv<+>, Tv<->, Tw<+>, Tw<-> series-connected on the upstream side and downstream side of the circuit and further connected to phase windings Lv, Lu, Lw of a brushless DC motor 1. A DC voltage output from a DC voltage circuit 3 is applied to the series circuits of the switching circuit 4. One of the upstream side switching element in one of the series circuits of the switching circuit and the downstream side switching element in a different one of the series circuits is continuously set in the ON state (Fig 8), the other switching element is intermittently turned ON, and the switching elements to be turned ON are sequentially changed so as to sequentially energize the phase windings of the brushless DC motor. In this case, the switching element, which is one of the switching elements to be turned ON and which has been set in the ON state, is continuously set in the ON state for a initial preset period of time and one of the switching elements which is newly turned ON is intermittently turned ON for the initial preset period of time. Alternative control sections 10 are described (Figs 7 10 and 19). The construction of the motor is described (Figs 2 - 6) and the motor may drive a compressor (60) of an air conditioner. <IMAGE>

Title: Shot tracking device
Inventor: EDWARDS GEOFFREY DAVID
IPC: F41J5/06
Filed: 1994-05-13
Abstract: A source of a high speed missile is determined by detecting the shock wave generated by the passage of the missile using a plurality of blast gauges 1 - 4 and using the amplitude and direction information from the gauges to calculate the azimuth angle of the track of the missile, the elevation of the track, the miss distance from the location of the gauges and the velocity of the missile on at least one point along its track. Each blast gauge comprises a spherical fairing containing four pressure sensors whose positions on the surface of the sphere form the apices of a tetrahedron. Preferably four blast gauges are used laid out in a symmetrical three-dimensional array. The four gauges can form the apices of a tetrahedron in which one face lies in a horizontal plane.

Title: Spark ignition engine charge intake system
Inventor: MA THOMAS TSOI-HEI
IPC: F02B31/00
Filed: 1994-12-31
Abstract: Two intake ports 14, 16 are connected to a single cylinder intake valve 10, one 14 shaped to direct a first flowtangentially near the outer periphery of the cylinder and the other 16 shaped to direct a second, swirling, flow towards the centre of the cylinder, the second swirling flow having the same direction of rotation as that of the first flow. Fuel is contained the flow through the port 16 or introduced into the second swirling flow within the cylinder thereby producing within the cylinder a charge that is radially stratified with a combustible mixture concentrated near the centre of the cylinder. The flow rates through the two intake ports 14, 16 may be independently varied to vary the relative angular momentum of the two flows at the boundary between the two flows in the cylinder. In this way the extent of mixing of the two flows and the degree of radial stratification may be controlled. <IMAGE>
