Title: Method for adjusting the axial play between the rotor and stator of an electric motor
Inventor: BLICK KLAUS
IPC: H02K5/167
Filed: 1985-08-16
Granted: 1989-06-29
Abstract: The axial play is adjusted by means of a sliding sleeve (32) which is held pre-magazined in a push fit in a recess (33) in the collar (31) of an insulating end disc (3); in order, despite the tolerance values which are normal in the case of mass-produced products, to be able to ensure a smooth, defined axial adjusting movement of the sliding sleeve (32) even in the event of intrinsically excessive compression between the collar (31) and the sliding sleeve (32), the sliding surface between the sliding sleeve (32) and the collar (31) is wetted with a sliding fluid (34) before adjustment of the axial play; a resorcinol solution is preferably used as the sliding fluid, which dissolves polyamide and bonds after the solvent has evaporated, so that, after adjustment of the axial play, the sliding sleeve is additionally fixed in its adjusted position. Said method is suitable for use for small motors, especially auxiliary drives for electrically powered motor vehicles. <IMAGE>

Title: Method and device for time division multiplex operation of a changing number of stations operating autonomously on one communications channel
Inventor: STEIN HERMANN
IPC: H04L12/28
Filed: 1986-02-07
Granted: 1987-04-16
Abstract: In the time division multiplex operation of autonomous transceiver stations on the same communications channel, a favourable throughput of variable-length data blocks is possible if unnecessary transmission gaps are avoided by adapting the transmission intervals to the number of received stations. This is achieved even without a higher-order station by indicating and evaluating future transmission times, the next intrinsic transmission time being determined at the start of each transmission from the previously received information relating to the future transmission times of the remaining stations as the transmission gap with the associated duration of the intrinsic transmission time which follows bridged transmission gaps, the sum of whose lengths corresponds at least to the longest transmission duration of the stations. The future transmission time is transmitted as information and is subsequently transmitted at the determined transmission time. The transmission sequence can be adapted according to the urgency of the data or to special operating conditions by controlling the number and length of the bridged transmission gaps and by means of information characters in the data block. <IMAGE>

Title: Ascertaining slip between railway wheel and drive friction roller - applying latter to bogie during machining for re-profiling
IPC: G01N19/02
Filed: 1990-01-23
Granted: 1991-03-07
Abstract: A method of accurately determining the slip between the periphery of a railway wheel (8) and its friction roller drive (7) during the reprofiling of a bogie wheel pair (1) is based on a comparison of their relative r.p.m. or peripheral velocities. For this purpose a tachometer wheel (16), ideally of similar external profile to the roller (7), is placed in rolling contact with the railway wheel (8) under sufficient pressure (18) to obviate slip.  In conjunction with the known rotational speed of the friction roller (7) a direct determination of slip in the processing plane of the railway wheel (8) is thus  enabled. USE/ADVANTAGE - Measurement of slip caused by cutting tool load is continuously determined during wheel reprofiling so that changes in wheel diameter are fully accounted for.  Accurate understanding of slip condition is important indicator for optimising cutting parameters e.g. speeds, feeds, depth of cut etc.

IPC: C04B33/32
Filed: 1990-04-27
Granted: 1991-08-08
Abstract: The tunnel kiln is used for firing ceramic products contg. combustible or gasifiable components. The gaseous components evolved in the heating zone (A) are drawn through flue gas openings (5) near the kiln inlet (4) and pass in forward and backward directions through a channel system (8,8'). The channel system extends within the kiln wall (6), over the entire length of the heating zone to a suction pipe connected to a chimney near the kiln inlet (4). The channel system (8,8') comprises a first channel (8), next to the kiln interior (7), in which the flue gas flows in the direction towards the firing zone, and a parallel second channel (8'), remote from the kiln interior (7), in which the flue gas returns under heat exchange conditions in the direct towards the kiln inlet (4). USE/ADVANTAGE - Tunnel kiln for firing ceramics which give off combustible gases. The kiln does not require fans, valves and special circulation systems with external heat exchangers for oxidising fumes and the design of the kiln interior is independent of the fume disposal channel system.
Patent DE-4029263-C1 (DE)
IPC: A24C5/36
Filed: 1990-09-14
Granted: 1992-02-13
Abstract: On the one hand, the invention provides an apparatus for reclaiming tobacco from defective cigarettes, in which there is provided coaxially relative to a recessed drum (7) a perforated drum (8) having receiving bores (14) for the defective cigarettes (16) to be processed, said perforated drum (8) rotating in the same direction as the recessed drum. Via a control device which comprises, in particular, as the essential part a control ring (26) connected fixedly in terms of rotation to the perforated drum, various pressure applications are then carried out via a timing disc (51) under the control of the work cycle, in order to blow the tobacco out of the defective cigarette and then subsequently to blow the empty cigarette tube (30) out of the receiving bore. Furthermore, a suction pressure is applied to the receiving bores of the perforated drum, in order, before the blowing-out operations, reliably to suck the defective cigarette to be processed into a predetermined stop position in the receiving bores. By means of a fixing device (17), the cigarettes are held firmly in the receiving bore before the blowing pressure for blowing out the tobacco is applied. After the fixing is released, the cigarette tube is then conveyed out of the receiving bore to a separate blowing-out device by means of a blowing pressure applied via the control ring. 
<??>Also, the invention provides a method for operating such an apparatus, which allows a fully automatic work cycle in the apparatus for reclaiming tobacco from defective cigarettes.

Title: Method for monitor three insulation of three electrical supply lines - involves comparing individual assembles and parts of electrical installation lying opposed on each potential
IPC: G01R31/02
Filed: 1990-11-28
Granted: 1992-04-16
Abstract: Two DC voltage sources (Ub,Uz), which deliver a positive and a negative supply voltage, and which with one of their two poles (+;-), are connected together at a supply line (m). Whereby respectively in an assembly (11,11'), a measurement voltage (U) is determined continuously between two identical supply lines, and is monitored regarding its position, within an upper movement window (17) lying in a positive measurement region (Ub), or a lower movement window (37) lying in the negative measurement region (Uz). The two movement windows, are respectively limited by an upper and a lower trip voltage (URpf;-URmf,-URzf) which are given on one hand from a specified threshold value (Rw) and on the other hand from the actual total resistance (Rg). The resulting total resistance (Rg) from a parallel circuit of the three unknown insulation resistances (Rp,Rm,Rz) is computed in at least one two stage test phase. In which a first and then at least a second reference resistance (R1,R2) is connected in parallel to the same insulation resistance (Rp,Rm) are measured, as well as the respectively resulting reference voltages (U1,U2) after the transient oscillation operation (T1,T2), from which new trip voltages (46',47') are computed, which determine a new movement window (17') for the future monitoring, and an alarm is then activated, if the determined measurement voltage (U) lies outside the determined measurement window (17'). ADVANTAGE - Reliable method is developed, so that despite large number of insulation resistance to be monitored per assembly, monitoring is managed with only one measurement voltage.
