Title: Improvements in or relating to methods of, and apparatus for, the manufacture of information storage devices employing thin magnetic films
Inventor: JAMES JOHN BERNARD
IPC: G11C5/12
Filed: 1964-08-12
Abstract: 1,082,384. Magnetic storage apparatus. INTERNATIONAL COMPUTERS & TABULATORS Ltd. July 8, 1965 [Aug. 12, 1964], No. 32911/64. Heading H3B. In the manufacture of a thin film store comprising an area of thin film on a substrate provided with a plurality of spaced-apart notches, magnetic switch cores threaded on a conductor which is wrapped around the substrate, are located in the notches, electrically conductive connections being made between turns of the conductor to form a plurality of conductor loops each coupled to a respective core and to the film area. A thin film plane 1 comprising thin film 3 on a substrate 2 provided with notches 4 along one edge arranged at 45 degrees to the faces of the substrate is supported by chucks 10, 11 in a conventional coil winding machine. In operation conductor 20 is secured to the back of the substrate 2 which is then rotated to wind on a few turns of conductor and then positioned with the notched edge uppermost, being rotated slightly past the point at which it extends from the end of tube 23 supporting the conductor and carrying cores 22. Block 18 is then moved to the right causing fork-shaped member 27 to move relative to the conductor 20 so that core 22 supported thereby falls towards the notches 4. Rotation of the substrate is resumed and the block 18 is moved back to its normal position on carriage 14 which action causes the core 22 to be engaged with a notch 4. During the second half of each revolution of the substrate escapement mechanism including arms 24, 25 is operated to release a further core to member 27. Carriage 14 is advanced during rotation of the substrate by means of leadscrew 16. At the end of the winding process the winding is formed into a plurality of separate loops by soldering all the loops to a conductive strip laid along the lower edge of the substrate, Fig. 2 (not shown), the loops forming word drive conductors. The substrates 2 may be held in back-to-back relationship and if they are not electrically conductive a foil layer may be introduced between the substrates of each pair. A serpentine digit conductor formation may be interlaced through an assembly of substrates. Instead of milling the notches 4 in the substrate they may be preformed in strips which are subsequently attached to the substrates. If a two core per bit arrangement is employed a switch core 22 is dropped from the member 27 every two complete revolutions of the substrate 2. Two or more conductors 20 may be wound concurrently.

Title: Electrical winding and microphone mountings
IPC: H03H3/013
Filed: 1976-08-06
Abstract: When calibrating mechanical resonators, consisting of a ferromagnetic material, for electromechanical filters by means of a sand blasting or laser erosion device, the resonators are excited into mechanical oscillations via the alternating field of a coil and the frequency of the oscillations of the resonators is measured with the aid of a microphone. To obtain an interference-free microphone output voltage which is as high as possible, the microphone (4) must be arranged in the area of the first anti-node of the air column located between resonator (1) and microphone, and thus closely adjacently to the resonator. To reduce the great wear of the microphone (4) and of the excitation coil (3), which therefore occurs during the calibration process due to reflected sand grains or ejected particles of material, a closed protective housing (9) is provided which exhibits a removable protective plate (5) consisting of insulating material and facing the holder for the resonator (1). Inside the protective housing (9), a sleeve (7) enclosing the microphone (4) and protruding with one end through a hole in the protective plate (5) and displaceable for moving this end close to the resonator (1) is arranged. Two ferrite core pieces (6) are guided through the protective plate (5). The excitation coil can be displaced inside the protective housing (9) so that its core (11) comes to rest against the two core pieces (6). <IMAGE>

Apparatus for taking twist out of material in twisted rope form comprises a turntable or other rotatable part, supporting the twisted material and from which the material is fed, driven by a reversible drive in combination with a direction controlling device operated by the material in twisted rope form and acting to cause the drive to rotate the turntable &c. in one or the other direction according to the direction in which the control device is rotated by the rope. The rotatable materialsupporting part may be the basket of a hydro-extractor above which the direction-controlling device is mounted. As shown, the latter comprises two pairs of resiliently-mounted rollers 24, 27 carried by a frame 15 rotatable, by means of four rollers 4 and four rollers 8, in races formed by fixed rings 2, 9, 5. Frame 15 is biased by a weight or other means so that it normally takes up an angular position in which an electrical contact 29 carried by the frame is disposed midway between spring contacts 31, 32, Fig. 3, carried by ring 5. In operation, material is drawn from the hydroextractor, between rollers 24 and 27 and over a pulley 35. If a twist is present in the material passing between the rollers it will cause frame 15 to rotate so as to close contacts 29, 31 or 29, 32. The circuit thus closed causes rotation of motor driving the hydro-extractor in such a direction as to remove the twist.

Abstract: 396,812. Zeroizing-mechanism. WALTER, R. H., 121, Kingsway, London, and RUSSELL, N. L., Rusrene, Wickham Court Road, West Wickham, Kent. Feb. 6, 1932, No. 33882. Divided on 387,358. [Class 106 (i).] One or more of the indicators of a length-measuring machine are returned to zero by the shortest path. As shown, the shaft 19 is rotated through gearing 20, 21 one revolution for each unit length of fabric &c. measured by the drum 18. This shaft 19 carries a fractions dial 22 for the salesman and drives through gearing 23 another fractions dial 25 for the customer. The two units dials 28, 33 are connected by skew gearing 30, 31 and are driven by a ten-toothed wheel 37 and a single tooth 38 on the sleeve of the dial 22. The two tens dials 29, 34 are connected by skew gearing 35, 36 and are driven by a ten-toothed wheel 49 and a single tooth 48 on a shaft 45 geared oneto-one with the shaft 32. When the lever 58 is depressed to cut the fabric a finger 98 on the shaft 57 lowers the pressure roller 83 and through levers and links 60, 62, 61, 76, 78 rocks two shafts 63, 79. The shaft 63 moves the tooth 38 out of gear with the wheel 37 to allow the fractions dials to be zeroized by means of the spring-pulled lever 54 and a heartshaped cam 52 secured to the gear 21. Should the cam 52 be in a dead-centre position, a finger 64 on the shaft 63 hits a pin 65 on the wheel and moves the cam from such position.
