A platform 10 is moved along the column 4 by a lead screw 11 and is provided with three milling cutter heads 16, which are mounted on tool carriers (17) and provided with individual drives (18), Fig. 2 (not shown). After each group of slots has been machined, the heads (17) are moved around the platform 10 into the next required alignment. The ribs are welded into the machined slots electrically. An attachment 19 is fastened to one of the ribs 9 and then a drive link 20 is fixed to the platform 10 and placed over the attachment 19 by a spacing disc to prevent tangential displacement of the platform during machining. All the ribs not being machined are similarly secured to the table. After milling the required number of surfaces on the ribs, the cutter heads 16 are positioned for milling the next set of ribs and the drive links 20 are placed over to the milled ribs after removing the attachments 19. When all the ribs have been machined the frame is removed from the fixture for placement of the core laminations.

The liquid, which is usually the same as that which gives off vapour in tank 9, is supplied to vessel 17 from reservoir 6 through pipe 51, coil 53 and line 26. The liquid in vessel 17 is preferably maintained at a temperature of about -18C by withdrawing some of it through line 27, passing it through heat exchanger 45 which contains chiller 36 and then returning the cooled liquid to the vessel through spray head 30. Air is discharged from vessel 17 through bleed-off line 48. Liquid is withdrawn from vessel 17 through line 25, the casing of heat exchanger 50 and coil 71, and is sprayed into flash separator 19 where air and vapour are released, and then flow through line 61 to compressor 13. The separated liquid flows from separator 19 to reservoir 6 through line 62.

Filed: 1971-12-15
Abstract: 1330987 Radio navigation TULL AVIATION CORP 15 Dec 1971 [7 Jan 1971] 58308/71 Heading H4D A transmitting system for a guidance system comprises a beam of radio energy scanned on both sides of a plane and in a direction perpendicular thereto wherein the beam is modulated by two different modulation signals whose ratio is a function of the scanning and which is less than one on one side of the plane, greater than one on the other side and equal to one at the plane and the scanning frequency is at least twice the highest modulation frequency. In an instrument landing system antennµ 24A-32A radiate sequentially the carrier frequency energy derived from oscillator 62. The antennµ radiate in different directions spaced at 6 degrees for the azimuth guidance or 1À4 degrees for glide slope control. The oscillator signal is mixed with an offset signal to determine the operating channel, and is then modulated by the tone signals at 90 Hz. and 150 Hz. and a 1020 Hz. signal which identifies the ground station. The modulated signal is fed in turn to the five antennµ via bistable elements 42-48 which are controlled through OR gates 36-40 by scanner 22 which also controls programmer 52 to vary the ratio of the modulating tones. The ratio may be the relative amplitude of the tones or the length of pulses modulated by the tones. The receiver (Fig. 4, not shown) may be in tandem with a standard V.H.F. I.L.S. receiver and display and utilizes common processing equipment and display. The system is also stated to apply to controlling water vehicles. The antennae may be separate, be a single movable element or a phased array and the glide slope may be varied by altering the direction at which the modulation ratio is unity.

Abstract: 1430810 Feeding sheets RANK XEROX Ltd 28 Dec 1973 59956/73 Heading B8R A plurality of pile supports 31, Fig. 2, are mounted side by side in almost vertical position, and each support has a pair of separator rollers 33, the assembly being movable in a direction perpendicular to the plane of the sheets to bring a selected pile and rollers into a feed position, wherein sheets are fed between guides 34, 35 to a sheet detector and then to a feed gripper bar 37. The guide 34 is moved out of the path of the assembly by a solenoid 38 during pile selection. To facilitate access to any pile, a plurality of frames are pivoted along one side edge, and each frame carries a pile support on one side and the separator means for the next lower pile on the other side. Each pile support 41, Fig. 4, includes a rear guide 45 and an adjustable side guide 44. Locks 55 secure the supports together, and an interlock arrangement prevents opening of the assembly at more than one place at a time. Cams 52 actuate microswitches when the height of a pile drops below a certain amount. The supports are accommodated in the cabinet of a copying- machine, and pressure sensitive switches stop the drive for selecting a pile if an operator's hand is caught.

Title: Photo-electric Displacement Transducer
IPC: G01D5/26
Filed: 1979-07-19
Abstract: An apparatus for the determination of displacement, particularly for use as the position sensing element in a servomechanism for a read/write head on a data storage disc, produces a plurality of displacement indicating signals (4). The signals are such that they possess a sum ( SIGMA ) or other combination which is independent of the displacement and the result of that combination is compared with a predetermined level (9). The amplitudes of the signals are collectively adjusted such that the result of the combination is equal to the predetermined level. This has the effect of cancelling long and short term drifts on the signal amplitudes e.g. due to changes in light source 1. The light passes through a moving scale 2 and fixed scale 3 to detectors 4 giving sets of signals phased 90 DEG  apart. <IMAGE>

Patent GB-2031237-A (GB)
Title: Electrical circuitry for feeding an A.C. motor
IPC: H02P4/00
Filed: 1979-08-31
Abstract: The present invention relates to electric circuitry for applying different supply voltages to a synchronous a.c. motor 5 for driving a clock. The voltages are applied via a series resistor, which consists of a PTC resistor 10 that is bridged by a capacitor 9. In that circuitry, a motor is used that is designed for a supply voltage of or below 24 volts. If the supply voltage is low (24 volts), the PTC resistor will have a low resistance and for this reason exerts no influence. If the supply voltage is high (220 volts), the PTC voltage will have a high resistance so that the motor current is mainly controlled by the capacitor. Zener diodes 11 may be connected across the motor. <IMAGE>
