Patent GB-1121102-A (GB)
Title: Adhesive tape applicator
IPC: B65H81/06
Filed: 1965-08-10
Abstract: 1,121,102. Applying adhesive tape. METEOR A.G. 10 Aug., 1965 [10 Aug., 1964], No. 34237/65. Headings B8F and B8G. An apparatus for winding adhesive tape around a body 15, Fig. 1, comprises a tape supply 1, a driven roller 4 for withdrawing tape from the source 1, displaceable means 6 and 11 to 14 for forming a loop length of the withdrawn tape prior to each winding operation, a pivotable support 22 for pressing the tape 1a against the body 15, means 17 preventing return feed of the tape, and a frame 20 mounted for raising and lowering movements co-operating with the support 22 to enable the tape to be brought into contact with the body to be wound. Operation.-At the start of an operation the slide member 11 and pulley 6 are at the lefthand end of the slot 12 so that the tape loop about pulleys 5, 6, 7 is at its maximum. The support 22 at the start is at a setting tilted away from the body 15, Fig. 2 (not shown), To start the operation the handle 18 is raised to the phantom line position to raise the frame 20 and cause it to close a switch 57. This causes a control mechanism 42 to actuate a valve relay 56 and cause pressurized air to displace a piston 28 to the left to rock the support 22 about its pivot 8a so that a lower shoe 9 of the support presses the leading end of the tape 1a against the body 15 as illustrated in Fig. 3 (not shown). The handle 18 is then rocked downwardly to its full line position so that the frame member 20 and the support 22 are lowered to a setting in which the upper shoe 10 bears against the coil body. The body 15 is then rotated and it winds tape 1a on to it, the slide member 11 during this time moving continuously towards the right of Fig. 1 until a cam (51) on the member 11 contacts terminal switch 23. When this happens a cutter knife 16 is actuated and it cuts tape 1a. Thereafter a button 25 on the handle 18 is actuated to cause control mechanism 42 to act upon the valve relay 56 to allow the pressurized air to escape from the cylinder 21 and so allow the support 22 to rock away from the coil body. Actuation of the button 25 also causes the control mechanism to actuate relay 41 so that the drive motor 40 is started and the roller 4 pulls more tape off the supply roller 1 until a new tape loop 1b is formed, the length of the tape loop being determined by a cam surface (52) on the slide 11 contacting a switch (24) to cause the relay 41 to do-energize and to stop the motor 40. The apparatus is then ready to apply a tape to a new coil body in the manner described. The spacing between the cams (51), (52) is adjustable to vary the length of the loop 1b. Instead of the roller 6 being located on a slide member 11 it can be mounted on a lever movable through an arc. The tensioning, in either case, can be by a spring 13 or by a weight.

Title: Engine torque control system
IPC: G01L3/00
Filed: 1972-07-21
Abstract: 1393380 Measuring torque electrically DRESSER INDUSTRIES Inc 21 July 1972 [21 July 1971]  34251/72 Heading GIN [Also in Division G3] The torque on an engine is controlled in response to the difference between electrical signals representative of actual and desired values for the torque, the desired value being subject to limitation by a third electrical signal related to an engine parameter. In the embodiment an I. C. engine drives a compressor and the torque is controlled by relay operated "compressor clearance pockets". The actual torque signal is derived at 15 from the engine speed 16 and horsepower 14, the latter in turn being derived at 13 from measurements of the differential pressure across an orifice in the fuel line, the static pressure of the fuel and its temperature. Circuits comprising amplifiers and multipliers for performing the torque and horsepower calculations are fully described but not explained Figs. 3, 4 (not shown); the horsepower is expressed as a percentage of rated horsepower and is assumed to be directly proportional to fuel flow. The desired torque is set on a local or remote potentiometer at 17, 18, 19 and compared with an "allowable torque" signal at 25. This is determined by a transistor circuit 20 also Fig. 9 (not shown), in response to a measurement of scavenging air temperature and allows the engine to be operated, e.g. to 125% of nominal full load, for suitable temperatures. The output of 20 is clamped to 100% full load by circuit 22 if the temperature signal is lost. The lower of the two inputs to 25 is compared with the actual torque signal at 26 in a milliammeter Fig. 6 (not shown). If its pointer reaches upper or lower limits a voltage is produced on the appropriate line to a timing circuit 27 in which time delay relays are arranged to produce, after a delay (e.g. 20 secs), a signal of prescribed duration (10 secs.) which operates the compressor clearance pockets 29 in the appropriate (load or unload) direction. The delays prevent too frequent correction. If the torque signal is lost, or if the torque exceeds that allowed by a given percentage, an unload stop is made. Provision is made at 23 and 24 for alarm and eventual shutdown if the torque remains excessive.

The screen 16 is mounted on isolating coil springs 18. Eight elastomeric blocks 36 mount each end of the tubular member 34. Each block (Fig. 3) has a stiffness ratio (compression-shear) of between 4:1 and 10:1. The pre-compression of the blocks is adjusted by bolts 45 and shims 47. The rotary vibrator 28 consists of a shaft 60 rotated by a motor 65 and carrying eccentric weights (63, Fig. 2 not shown). In the embodiment of Figs. 4 and 5 (not shown) the screen is horizontal, instead of inclined, each end of the tubular member is mounted by only four elastomeric blocks, and there is a motor driven shaft carrying eccentric weights at each end of the tubular member. The vibratory movement of the screen can be varied between circular, elliptical or almost straight line movement by removing, adding or adjusting the elastomeric blocks 36 which transmit the vibrations.

Abstract: 634,426. Transformers. OLTHOF, M., and OLTHOF, T. (trading as TRANSFORMATORENFABRIEK FIRMA GEB. OLTHOF). Dec. 30, 1947, No. 34582. Convention date, Dec. 19, 1941. [Class 38 (ii)] In a welding transformer adapted to regulate the current thereof, a secondary winding is in three portions 2, 3, 4, the portion 3 being on a first limb of a core also carrying a primary winding 1, the portion 4 in series. with 3 and on an adjustable magmetic shunt 5, and the portion 2 in parallel with the portion 3, 4 and on a second limb of the core. The regulation of the secondary circuit current depends upon the position of the shunt 5 which may be rotated about a vertical axis. When the shunt 5 is in a closed position with the M.M.F.'s of the portions 3, 4 additive, the effect of the shunt 5 is greater and the portion 2 carries the greater part of the load current. When the shunt 5 is turned. through 180 degrees the M.M.F.'s of the portions 3, 4 are opposed and the effect of the shunt 5 disappears. The range of the current adjustment is increased and the drooping characteristic desirable for welding work is maintained, while the no-load voltage does not change.
