Patent EP-0251708-B1 (EP)
IPC: B01J37/02
Filed: 1987-06-25
Granted: 1993-09-29
Abstract: A method of making a catalyst composition comprising an activated alumina coating stabilized against thermal degradation includes applying a coating of alumina having one or more platinum group metal catalytic components dispersed thereon onto a carrier substrate and calcining the coating. The calcined coating is then impregnated with a solution of a thermal stabilizer-precursor and calcined again to provide a thermal stabilizer in the alumina. Bulk ceria, optionally an aluminum-stabilized bulk ceria, may also be added to the composition, preferably at specified minimum levels, including a high purity bulk ceria on which one or more non-rhodium platinum group metal catalytic components, e.g., platinum, optionally, are dispersed. A separate aspect of the invention provides for a method of making a catalyst composition including dispersing one or more platinum group metal catalytic components on an activated alumina and calcining the combined alumina and platinum group metal catalytic components. The steps are carried out under limited acidification conditions whereby at least minimum dispersions of the platinum group metal catalytic components are attained. The invention also provides for catalyst compositions resulting from either or both the foregoing methods.

Title: Burner for drying or gas-purification processes
IPC: F23D14/36
Filed: 1988-07-26
Granted: 1992-02-12
Abstract: For drying or gas-purification processes, and consequently also for intermediate heating of gas or exhaust air, a burner (1) is used, in which the combustion gas is supplied, via a combustion gas pipe (4) and a combustion gas feed (5), in combustion gas distributors (3) which run in the longitudinal direction and in which combustion gas outlets (6, 7) are provided. The necessary combustion air comes via an air distributor (10), after passing a diffuser plate (17) and a pass-through plate (14) into the region of the combustion gas outlets (6, 7). Parallel to this, combustion air is guided, via additional combustion air channels (12) and producing a combustion air part flow (24, 25), past the combustion gas distributors (3, 3'). These part flows (24, 25), after circulating around the combustion gas distributors (3), are supplied to the flame, so that combustion in two stages takes place. On the combustion gas distributors (3) or on the angles (32) which form the combustion air flow channel (12), extension plates (20, 21) are arranged, which reliably prevent a return of the inert gas into the flame. Thus even air flows or gas flows with high contents of CO2 and H2O can be dried or heated safely.

Title: Method and apparatus for forming round bales of crop material
IPC: A01F15/07
Filed: 1988-08-23
Granted: 1991-12-27
Abstract: In the formation of tied rolled crop bales (R), the period of time between the closing of the tying means on the circumference of the rolled bale, the ejection of the rolled bale and the closing of the press chamber is critical, because the crop fed continuously in large quantities should not disrupt either the final tying or the ejection. With the new method and the apparatus suitable for carrying it out, a time buffer for this phase will be provided, without any appreciable outlay in terms of the construction of the apparatus. For this, intermediate storage is carried out in two steps one after the other, in the first step the crop also being compressed in the feed channel, and in the second step up to the closing of the press chamber the crop also being stored intermediately in the press chamber, each time being separated from the rolled bale. For this purpose, the apparatus has a press roller equipped with press blades and located in the feed channel, and a separating element (T) which, in a build-up position, can be moved with the crop (G) through the inlet (8) into the press chamber (4).

Title: Longitudinal steering linkage for truck with interaxle yokes
IPC: B61F5/44
Filed: 1988-07-26
Granted: 1992-12-16
Abstract: This invention applies the linkage connected between the interaxle yokes(16,18) of a truck and a railroad vehicle car body so as to create radially steered alignment of wheelsets(12,14) on circular curves without reference to the truck frame. Forces exchanged between the wheelsets and the car body are essentially longitudinal and no significant lateral forces are created on the truck frame or car body from the steering action. The steering linkage (34,40,46) utilizes the longitudinal component of relative motion of a point on the car body with reference to the vehicle truck to cause relative pivotal movement of the interaxle yokes thereby guiding the wheelsets to a radial alignment. Radial alignment is achieved by suitable proportioning of the links of the mechanism.

Abstract: A pulse train processor includes a plurality of parallel input, serially coupled pulse discriminating modules one for each of the consecutive pulses of a pulse train characteristic of a magnetic strip or resonant tag target signal produced in a magnetic interrogation zone such as found in retail clothing or library theft prevention applications. Each module is tailored to the particular expected characteristics of the corresponding pulse of the pulse train, and the modules are serially enabled and an alarm is triggered if and only if the expected characteristics of the several pulses are sequentially present from the initial pulse to the last pulse of the received pulse train. The modules are self-resetting in the event that the pulse characteristics of any of the pulses are other than the expected pulse characteristics whereby the pulse train processor is substantially continuously armed. The modules are responsive to pulse sequence, pulse polarity, pulse height, and minimum and maximum duration of the several constitutive pulses of the pulse train whereby an ultra-high detection reliability is provided.

Abstract: During shunting, it occasionally occurs that a points-circuit zone is prematurely reported as free below an unusually long vehicle by the associated track free report device. Special measures then have to be taken in order to prevent the points turning below this unusually long vehicle. For this purpose, the invention provides for the free report signal of the track free report device (GFAW) only to be evaluated as a free report of the associated track section if it has been ensured that all the axles of a vehicle (FZ) or a group of vehicles travelling over the section have previously travelled into the section. For the first section in the driving direction of a track system, this is determined by an indicator (EL) which detects the completion of the passing of the vehicle or of the group of vehicles. The indicator signal (EFWA) which occurs earlier in time is connected to the free report signal (GFWA &uarr& ) of the track free report device to form a vehicle end code (FEZA) which indicates that the vehicle or the group of vehicles has left the first track section. This vehicle end code (FEZA) is connected, as the vehicle or group of vehicles advances further, to the free report signal (GFZA &uarr& ) of the track free report device of the following track section to form a new vehicle end code (FEWB) for this section which indicates that the second section is completely cleared. This process continues as the vehicle or group of vehicles advances from section to section. <IMAGE>
