Title: Method and apparatus for coating three dimensional articles
Inventor: OTANI TATSUO
IPC: B05B12/08
Filed: 1994-04-07
Abstract: A method and apparatus (10) for powder coating three dimen-sional articles (12) carried on a conveyor (14) includes a controller (36) for controlling the rate at which coating material is discharged from a gun (16), so that the rate is proportional to the surface area of the surface portions of the article (12) as they pass the gun (16). Some surface portions topographically have a greater surface area which must be covered, while others are flat or have cut-out regions, requir-ing less coverage or no coverage at all. In powder coating operations, the discharge rate is controlled via automatic or programmed control of an electro-pneumatic air regulator (42) which regulates the supply of pressurized air to a powder pump (24) connected to the spray gun (16). The apparatus (10) assures uniformity in coating for a three dimensional article (12) with multiple surface portions of varying to-pography such as curves, angles, cut outs, etc., while minimizing the amount of wasted coating material.

Title: Excess speed detector with multiple light barrier
Inventor: ARPAGAUS CHRISTIAN
IPC: G01P3/486
Filed: 1995-10-24
Abstract: This equipment serves for the production of a shaft information for a lift plant. A cage (2) guided in a lift shaft (1) is driven by way of cables (5) from a drive motor (3) with a drive pulley (4). A redundant measuring strip (6) is mounted at one side of the lift shaft (1). A multichannel forked light barrier (7) is arranged at the cage (2). The measuring strip (6) consists of a markings track in the shape of a flag track (8) and a check track (9), which are each scanned by a light barrier. At those places, where a flag (10) stands at the flag track (8), a window (13) is arranged at the check track (9). The speed of the lift is measured by means of the flags (10) and the lift is stopped in the case of possible excess speed.      By reason of the arrangement of the flag track (8) and the check track (9), possible faults can be detected at the measuring strip (6), since one light barrier must always be interrupted by reason of the flags (10) and windows (13).

Title: Super d converter
Inventor: BARNETT ALBERT JOHN
IPC: B68C1/14
Filed: 1996-03-14
Abstract: To prevent a saddle from sliding rearward on a horse, a device known as a breastplate is attached to the saddle. The breastplate is attached to two metal D's in front of the saddle, on each side of the horse,and a third or central strap is secured to the breastplate and extends downward from the base of the horse's neck and between the horse's front legs for connection to the girth forming a part of the saddle. The two metal D's are usually installed by saddle manufacturers, however they dohave the tendency to come loose and separate from saddle when exposed to tensionfrom breastplate over a period of time. Replacing these D's is cumbersome, so it is with this in mind the inventor developed a method whereby the tension from the breastplate can be transferred from the saddle manufacturer's installed metal D's to a superior point of strength, the stirrup bar, without alteration to saddle or breastplate.

Inventor: BRODIE IAIN RICHARD
IPC: H04W16/32
Filed: 1994-12-02
Abstract: A cellular radio system includes three neighbouring cells (A3, A2, A1) which each have a number of channels (1 to 13, 14 to 26, 27 to 39, respectively) allocated for their use. A microcell M contained within cell (A1) is served by a separate base station. The microcell has available to it channels (1 to 16 and 21 to 26) from the allocations of neighbouring cells (A2 and A3). The base stations (A2, A3 and M) are controlled such that no channel is in use simultaneously in both the microcell (M) and cell (A2 or A3). This arrangement allows channels to be reallocated between neighbouring cells according to demand, without reducing the peak capacity in individual cells.

Title: Continuous casting facility and process for producing rectangular thin slabs
Inventor: PLESCHIUTSCHNIGG FRITZ-PETER
IPC: B22D11/108
Filed: 1995-01-20
Abstract: The invention is directed to a process and to a continuous casting installation for the production of thin slabs, preferably of steel with a predetermined solidification thickness of, e.g., 50 mm, in which an optimum surface quality and internal quality of the strand with minimal and predetermined solidification thickness and plant capacity, and accordingly minimal rolling effort, is achieved by the introduction and optimal combination of such elements as the following: continuous casting and rolling in the region of the strand guide (segment 0), hydraulically driven lifting platform, casting powder and feed thereof, immersion nozzle with specific flow cross section.  A qualitative adjustment of the above-mentioned parameters relating to the process and continuous casting installation results in a satisfactory supply of casting slag and bath movement in the cast surface compared with a standard slab with a thickness of 200 mm. These conditions from the crater end to the cast surface exert a direct influence on the superficial and internal quality of the strand and on the reliability of the casting process.

Abstract: A distribution network groups television program signals into service tiers. To provide these from unsynchronized MPEG streams without resynchronization, each stream, representing a single program signal is encapsulated into ATM cells with a virtual path(VP) identification of each ATM cell corresponding to the service tier and a virtual channel (VC) identification corresponding to the respective program signal. Payloads in cells having the same VP are scrambled using a scrambling key allocated to that VP and hence to the corresponding service tier, and are unscrambled by entitled subscribers using the scrambling key which is supplied to them individually using public/private encryption techniques.

Abstract: A vehicle door arrangement is provided including inner and outer panels. The inner panel has a through opening, a tubular grommet which is received in the opening and snap-fittingly secured to the inner panel, and a plurality of electrical conductors extending through the grommet. The through opening in the inner panel extends inwardly from a side edge of the inner panel. The inner panel has at least one ear extending transversely into the opening adjacent the side edge. The grommet is resilient and has a groove which extends inwardly from its outer periphery and whose outwardly facing bottom is shaped substantially complementary to the opening. The ear engages the bottom of the groove and deflects the grommet as the latter is transversely inserted into the opening until the grommet is fully received in the opening and the ear is aligned with a deeper portion of the groove whereupon the grommet, due to its inherent resiliency, returns toward its normal free state position and locks behind the ear to lock the grommet to the panel.
