Title: Method of and a device for reducing the influence of backlash  in the drive of a machine tool
IPC: B23Q5/56
Filed: 1973-12-31
Abstract: 1450078 Automatic control of speed G LUCHERINI 31 Dec 1973 [29 Dec 1972] 60295/73 Heading G3R In a system wherein a machine tool is driven by two motors each with a feedback speed control using a tachometric dynamo. When the detected torque on one motor approaches zero, speed control of both motors is maintained using the dynamo associated with the other motor. Each speed feedback includes a bias so that the two motors do not approach zero torque simultaneously, and the system is said to eliminate backlash in the machine tool drive.  As shown, motors 1, 2 with stabilized field currents, have associated dynamos 6, 7 and circuits 15, 16 that calculate the torque on each motor from the sensed motor speed and armature current. A bi-stable circuit 14 switches the speed control to one dynamo when the calculated torque on the other motor approaches zero. The output of the bi-stable switch is compared with a speed reference 19 to control the armature currents in the motors using amplifier 12.

Abstract: 1,246,815. Detecting signals in a voltage range. INTERNATIONAL STANDARD ELECTRIC CORP. 19 Dec., 1968 [29 Dec., 1967], No. 60324/68. Heading H3T. A circuit for detecting whether an input voltage is within a given range comprises two transistor long-tail pairs Q 3 , Q 4  and Q 1 , Q 2  having the input voltage S applied to the bases of one side of the pairs and having reference voltages corresponding to the two limits of the range applied to the other bases, the collectors of corresponding sides being connected together and to a detector which indicates the desired condition. When the input voltage is between the reference voltages the common emitter current i 1  flows through Q 2 , and the similar current i 2  flows to Q 3  so that the voltage across the relay is zero. If the input is outside the range both transistors on one side or the other conduct and the relay operates. The relay is replaced in Fig. 2 (not shown) by a pair of transistors having commoned collectors, commoned emitters connected to a transistor acting as a Zener diode and having the output voltages from R 3  and R 4  applied to the bases.

IPC: B01J8/20
Filed: 1979-07-09
Abstract: Biomass growing on the surface of particulate material in an aqueous medium is detached and separated from the particulate material, and obtained as a relatively concentrated sludge by first removing some of the aqueous medium before the biomass detachment step. The thickened mixture of particulate material with attached biomass and aqueous medium is then subjected to shear forces to detach the biomass, and the particulate material is then separated from the mixture. The method is particularly useful where expanded or fluidised beds of the particulate material are used, such as in the water and sewage treatment industries. Apparatus is described for carrying out the method.

Title: Pressure-medium activated friction coupling for transmission of torque
IPC: F16D25/04
Filed: 1979-08-15
Abstract: In a friction coupling for interconnecting two machine members (1, 2; 11, 12; 21, 22) insertable one into the other, e.g. a pump impeller on a shaft, a pressure medium is contained within a space (3, 23), defined by a resilient wall (4, 24) and this space also encloses a reciprocating piston means (6, 26) producing dimensional changes in the wall by varying the pressure in the medium. The outside of the wall is adapted for frictional engagement with one member, the dimensional changes therein causing a wedging effect between the members. The piston means and the pressure medium are located within one member (2; 12; 21), in a space essentially made as a cavity therein sealingly defined by the wall facing the other member (1; 11; 22). The coupling can then be made in one piece in one of the two members intended for interconnection and can be kept completely within their contours. <IMAGE>

Title: Metal Disc Saw
IPC: B23D45/02
Filed: 1979-11-06
Abstract: In the starting position of a metal disc saw having a frame carrying a slide upon which a saw blade (1) is rotatably mounted, the saw blade (1) is on the opposite side of a fixed workpiece stop (4) to the workpiece (3), the axis of the saw blade (1) is above the workpiece (3) and the direction of rotation (5) of the saw blade (1) is opposite to the direction of movement of the slide (2) so that, during cutting the workpiece is urged against the stop (4). This reduces vibration and wedging between the workpiece and the saw blade because the workpiece stop (4) is rigidly secured to the workshop floor via a pillar (20) relative to which the machine frame is pivotable. The frame is pivotable and securable relative to the stop 4 to enable oblique cuts to be made. The slide is horizontally movable away from the starting position to effect a cut on the workpiece. <IMAGE>

Title: Vehicle wheel nut spanner
IPC: B25B23/142
Filed: 1980-01-28
Abstract: A spanner enables the wheel nuts of a motor vehicle to be tightened with the torque prescribed by the manufacturer. The spanner has a box spanner part (11) a lever (1) connected thereto, and a peg which is attached to the lever so as to project axially parallel, but in the opposite direction to the box spanner part. When tightening a wheel nut the operator stands with his full weight on the peg. To enable persons of differing body weights to achieve the same prescribed tightening torque, the radial distance between the box spanner part and the peg is varied. For this purpose, either the box spanner part (10) or the peg is displaceable relative to the lever. A lever scale determines the relative box spanner and peg positions for required torque, the spanner or peg being locked against movement. <IMAGE>
