Patent GB-930139-A (GB)
IPC: D04H1/55
Abstract: 930,139. Fibrous fabrics. CARL FREUDENBERG KOMM.-GES. AUF AKTIEN. July 15, 1959 [July 17, 1958 (2)], No. 24396/59. Class 42 (2). A method of making non-woven bonded fibre sheet comprises the steps of preparing a web of fibres of polyamides, polyesters, polyvinyl compounds, cellulose acetate or mixtures thereof at least part of which has a length of over 20 mm. and of which 5 to 50% have a melting or softening point which is at least 10 ‹ C. below the melting or softening point or decomposition temperature of the other fibre fraction, passing said fibre fleece through equally spaced rolls heated to about the melting or softening point of the lower melting fibre fraction, impregnating the thus resulting porous bonded fibre fleeces with an aqueous dispersion of synthetic resins of the group comprising polyvinyl chloride, maleic acid etherified with an alcohol having from 2 to 6 C-atoms, butadiene styrene, butadieneacrylonitrile or mixtures thereof so as to incorporate 10 to 40% of said resin based upon the weight of the dry fibre fleece, drying said impregnated fibre fleece at a temperature of about 100‹ C. and subsequently simultaneously subjecting it to a temperature of 50‹ to 150‹ C. and a pressure of 50 to 150 atmospheres. As shown in Fig. 1, bonding of the fibres is effected initially in consequence of activation of the binder fibres by passing the web between two spaced heated rollers without appreciable pressure. The web is then impregnated with resins whereupon the voids between the fibres are filled as shown in Fig. 2. The web is then subjected to a smoothing operation between heated calender rolls and emerges as shown in Fig. 3.

Title: Inverter and air conditioner driven by the same
Inventor: NAGAI KAZUNOBU
IPC: H02P6/06
Filed: 1993-12-16
Abstract: An inverter controlling an air conditioner including a brush less motor 35 serving as a compressor motor has means such as a microcomputer 44 detecting the rotational position of a rotor of the brush less motor 35 such as from signals obtained by comparison of each of terminal voltages of the motor windings 35u, 35v, 35w with a reference voltage V0 in order to determine a commutation time. In a normal operation, the microcomputer 44 forms, according to a normal energization signal forming pattern, energization signals corresponding to every commutation time at every occurrence of the corn mutation time, so that the motor windings 35u, 35v, 35w are sequentially energized. When for example frost forms on an outdoor heat exchanger (58, Fig 6) of a heat pump during a warming operation and a defrosting operation is necessary, the energization signals are formed according to a loss increasing energization signal forming pattern so that loss increasing energization signals for causing the rotor to produce counter torque are added to the respective energization signals formed according to the normal pattern. As a result, the brush less motor loss is increased and the brushless motor 35 generates heat. The generated heat is used for defrosting the outdoor heat exchanger (58). A drive circuit 46 synthesises the energization signal and a pulse width modulated (PWM) signal 45 to obtain a signal for driving the inverter. The input current to a rectifier 23 may be detected and further used to control the microcomputer 44 (Fig 9). The heat pump employed in the air conditioner is described in more detail (Fig 6). <IMAGE>

IPC: B60R21/34
Filed: 1994-03-22
Abstract: A vehicle-surroundings monitoring apparatus designed to be free from mistakenly identifying a lane marker on a road surface or a guard rail as a vehicle travelling in the blind spot of a nearby lane. A distance detecting section 1 - 4, 6 - 10 detects the distance to a vehicle 5 which is traveling in the blind spot of a nearby lane and which is captured by a plurality of windows as set 12 on a display screen 11. A detecting range restricting section 10 restricts the distance detecting range for each window to a predetermined range to thereby select as a nearby vehicle an object to which the distance is within the predetermined range. <IMAGE>

Title: Digital phase-locked loop using a numerically-controlled oscillator
Inventor: MEIER PETER J
IPC: H03L7/099
Filed: 1995-03-14

Title: Anti-lock brake system
Inventor: WISS HELMUT
IPC: B60T8/58
Filed: 1995-04-27
Abstract: In a vehicle anti-lock brake system, wheel speed signals U2 are normally converted in block 13 into activation times for brake pressure control valves. However, if drive train vibrations are present, the activation times are modified by a correction signal U3, which is proportional to a torsional moment detected in the drive train, to produce damping of the drive train vibrations. Drive train vibrations are present if it is determined, in block 16, that the speed VD at the differential of the drive wheels lies in a specific frequency range (e.g. 5 to 12 Hz) and if it is determined, in block 17, that a low-pass filtered curvature-signal, derived from acceleration at the differential, exceeds a specific threshold. The torsional moment is proportional to the difference between the engine speed and the speed VD. <IMAGE>

Patent GB-2289998-A (GB)
Title: Feed forward predictive analog-to-digital converter
Inventor: STONE WADE J
IPC: H03M1/20
Filed: 1993-03-25
Abstract: A linear predictive ADC employs a fully feed forward design to extend its dynamic range, allow greater speed of operation, achieve stable operation and eliminate a requirement for sample-and-hold circuits. A first quantizer (Qc) converts an input analog signal to a digital format, while a signal predictor (32) predicts a subsequent value of the input signal. After conversion back to analog format (34), the predicted signal is compared with the actual subsequent value of the input signal (30) to produce an error signal that is converted to a digital format by a second quantizer (Qf). The digital predicted signal is fed forward and combined (46) with the digital error signal to produce a high precision digital output. The analog error signal is amplified (38) prior to digitation to take advantage of the full bit capacity of the second quanitzer (Qf), and then digitally de-amplified (40) back to its original scale. Digital gain and offset adjustment mechanisms (44, 50) are provided to compensate for amplification/de-amplification mismatches and system offsets. <IMAGE>

IPC: B01F15/04
Filed: 1995-08-04
Abstract: Selected bulk ingredient materials are delivered from storage bins (10) to a mixer (12) and mixed with additives to from a dry feed mix. The dry feed mix is discharged into a holding bin (28), and then fed through a liquids adder (30). A flow sensor (48) detects flow of dry feed mix from the holding bin (28)to the liquids adder (30) and controls delivery of molasses to the liquids adder (30) for mixing with the dry feed mix. The molasses is injected at a molasses inlet (45) adjacent an inlet (35) of the liquids adder (30). A screw auger within the liquids adder (30) has mixing blades adjacent the inlet (35) for rapidly mixing the molasses with the dry feed mix to form coarse animal feed which is discharged through one of two outlets (36, 37) of the liquids adder (30).

Abstract: A parison 4 of hot thermoplastics material is delivered into a mould 1 comprising two mould halves 2, 3 which are closed towards one another. A stress force is applied to the wall of the parison 4 either by a projection 5 extending from one of the mould halves 3 and/or by blowing air at a low pressure against the parison 4 through a blow pin 10, to form a deformation in the wall of the parison.

Title: Exhaust manifold with double-walled insulated pipes
Inventor: YAMADA MASAHITO
IPC: F01N13/14
Filed: 1997-01-24
Abstract: The exhaust manifold has a plurality of double pipes 1, each of which includes an inner pipe 10 and an outer pipe 13, and a collecting pipe 3 to which each of the double pipes 1 is connected. The outer peripheral portion of the outer pipe 13 is secured to the collecting pipe 3 by a welded joint 52 and the inner and outer pipes 10, 13 are brought together with minute or zero clearance 7 downstream of the welded joint 52. Thus a thermal insulating layer 15 of air, which is formed as a closed space so that substantially no exhaust gas will penetrate it, is disposed on an inner peripheral side of the portion at which the outer periphery of the outer pipe 13 is secured to the collecting pipe 3. Owing to the presence of the thermal insulating layer, heat is not transmitted to the welded joint directly via the inner and outer pipes.
