Title: Asphalt mix
Inventor: SINGH OMROW JIM
IPC: C08L95/00
Filed: 1988-02-10
Abstract: A method of producing an asphalt mix for recycling comprises mixing a percentage Rc (by wt.) of reclaimed material according to the equation:- Rc = 100 - (RB x B<1>)/Bs where RB in the reclaimed bitumen is a percentage of total original asphalt, B1 is a blending index and BS is the percentage of bitumen required in the final mix. An asphalt recycling plant comprises three hoppers 10, 12, 14 for stone, sand and reclaimed bituminous materials. A conveyor 16 conveys material from for the hoppers, to a rotating steel drum 18. The drum is contained within an insulating sleeve 19 which is circularly spaced from the drum and a gas or oil burner 20 for heating and drying the materials in the drum is located within the sleeve 19 both the burner and the sleeve being stationary. The output 22 from the drying drum 18 feeds a mixing chamber 24 heated by a heat exchanger 28. The materials in the mixing chamber 24 are heated to a suitable temperature and are continually agitated and driven forward by rotation of a screw conveyor 26. <IMAGE>

Title: Ozone calibrating method
Inventor: SUGA SHIGERU
IPC: G01N33/00
Filed: 1989-02-23
Abstract: Ozone concentration is measured or controlled using uv absorptiometry, by charging air into a testing tank with its temperature controlled, measuring the disturbing gases generated from testpieces e.g. of rubber inside the tank, subtracting this value by a calculation circuit to make an ozone concentration zero, generating a necessary quantity of ozone by an ozonizer by use of the zero ozone concentration as a starting point, suspending the generation of ozone after the passage of a predetermined time, measuring once again an ozone concentration zero value, readjusting the shift of the ozone concentration zero value due to the change of the disturbing gas generation quantity, and repeating at least once the operation described above to control the ozone concentration to a desired value.

Title: Switching arrangement for the auxiliary pressure supply pump in a vehicle brake system
Inventor: SCHMITT ALBRECHT
IPC: B60T17/22
Filed: 1989-09-21
Abstract: A motor relay (9) is provided which is controlled by means of a switching contact (8) of a pressure switch (7) and which actuates an operating contact (11) to connect the motor (1) to the source of current (+UBatt) if the auxiliary pressure drops to the lower limit. If the pressure rises to an upper limit, the switching contact (8) is opened again. In addition, a switching contact (13) is provided which closes if the pressure drops to a pressure minimum and makes a brake warning lamp (15) flash up. Parallel to said lamp, an auxiliary motor relay (16) is inserted whose operating contact (18) actuates the pump motor (1) when, for example, the pressure switch (7) fails. The auxiliary motor relay (16) is released again as soon as the auxiliary pressure has exceeded the pressure minimum and has again risen to an auxiliary pressure which is still below the lower limit. …<IMAGE>…

Patent GB-901220-A (GB)
Abstract: 901,220. Gyroscopic apparatus. GENERALE AERONAUTIQUE MARCEL DASSAULT. Nov. 9, 1960 [Nov. 12, 1959], No. 38510/60. Class 40 (1). [Also in Group XX] In gyroscopic apparatus in which a motor M, Fig. 1, is connected to one of the suspension axes, 1, of a gyro, G, in order to process the gyro about a second axis, 2, an elastically deformable member, e.g. torsion-bar 4, is included in the transmission path between the motor and the gyro and a signal is developed, e.g. by the potentiometer 5, 6, dependent on the deformation of the deformable member and hence on the torque applied to, and therefore the precession rate of, the gyro. The signal may be applied as a negative feed-back signal to the motor drive amplifier 9 via a comparator 8. The preferred embodiment relates to the gyroscopic stabilization of the angular position of an airborne radar antenna. Gyro details. Fig. 4 shows the mounting of the gyro housing 10 on gimbal ring 12 by bearings 13, the ring 12 being in turn mounted on the pedestal 17 by further bearings, not shown, for rotation about the axis C1. The gyro rotor G2 is mounted in the housing 10 by bearings 11 and rotated by utilizing a portion of the gyro rotor as a motor armature G1 driven by the stator S. The radar antenna G3 is attached to the gyro rotor and rotated with it. The angular position of the gyro housing and hence of the radar antenna is controlled by motors in the apparatus base 23, Fig. 2, via a parallel linkage arrangement 20a and 20b, application of a torque to the gyro housing about axis 02, for example, being accomplished by rotation of link 19a about axis O1 and application of a torque about the second axis, normal to 02, being accomplished by rotation of housing B2 about the axis Y, shown in Fig. 5. The drive mechanism for rotating housing B2 about axis Y comprises a motor M1, Fig. 5, driving through gearing 3a a hub 25 attached to the driving end of a torsion bar 4a, the driven end of which is attached to housing B2. A potentiometer resistance element 5a is carried on an extension 25b of hub 25 while the slider of the potentiometer is attached to a sleeve 28 connected to the housing B2, the position of the slider on the resistance coil therefore being a function of the deformation of the torsion bar 4a and hence of the torque applied to tend to rotate the gyro housing. A similar drive arrangement including a second torsion bar is used to rotate link 19a about axis O.

Title: Papermaker's fabrics
Inventor: SUDRE PAUL LOUIS
IPC: D21F1/00
Filed: 1990-12-04
Abstract: A method for the manufacture of a papermaker's fabric is proposed which involves the provision of a multiply fabric having fold regions (15, 16) at its respective ends and the removal of cross-machine direction yarns (14) in such fold regions thereby to create seam-forming loops (17, 18). The loops (17, 18) may be interdigitated directly to receive a pintle wire into engagement therewith and thus form a seam, or may receive a spiral for seam-forming purposes. The method is of application to flat-woven or endless woven structures, and is of use in the manufacture not only of papermaker's fabrics per se but also in the manufacture of base materials for use therein.
