Title: Apparatus for mounting semiconductor devices on supports
IPC: H01L21/60
Filed: 1975-11-14
Abstract: 1481205 Semiconductor devices FERRANTI Ltd 14 Nov 1975 [21 Nov 1974] 50456/74 Heading H1K Semi-conductor devices 20 adhering to a tautly held flexible membrane 36 are individually prepared for mounting at the appropriate location on a lead-frame strip 31 by means of a reciprocating pin 40 which contacts the face of the membrane 36 remote from the devices 20 and displaces a selected device to below the membrane plane into an aperture which may comprise part of the apparatus or part of the leadframe strip and which is vertically aligned with the lead-frame. In the apparatus shown an array of separate devices 20 are arranged in a regular array on a membrane 36, e.g. of polyimide, polyester or polyamide, which is stretched taut on a jig 37. The jig 37 is displaceable horizontally to move the devices 20 one-by-one into vertical alignment with an aperture (26) Fig. 3 (not shown) in a masking strip adhering to the lead-frame strip 31 or with a recess (61), Figs. 8 or 9 (not shown), in the strip 31 itself. The pin 40 then moves down to displace the selected device 20 at least partly into the aperture or recess, and means such as a horizontally movable striker 48 may be provided to detach the selected device 20 from the membrane 36. The strip 31, with the apertured masking strip where this is provided, is advanced, a further device 20 is aligned with the new aperture or recess, and the process is repeated. For flipchip bonding heater means 49 are provided to solder the device contacts to the leads of the lead-frame. Modifications of the apparatus are described in which the apertured masking strip is separate from the lead-frame strip and has to be vertically aligned therewith, and in which a singly apertured masking member is employed, with which successive devices and lead-frame patterns are sequentially vertically aligned. In one embodiment a glass-fibre brush is used to sweep each device into contact with the trailing wall of the respective aperture in a masking strip so as to align the device and lead-frame contacts prior to soldering. Various forms of lead-frame strip are described for use in the invention.

Title: Improvements in or relating to thermo-electric ignition safety devices
IPC: F27D21/00
Filed: 1967-11-17
Abstract: 1,201,325. Burner controls. JUNKERS & CO. G.m.b.H. 17 Nov., 1967 [19 Nov., 1966], No. 52329/67. Heading F4T. A safety control device for gaseous fuel comprises within a housing 10, 11 an ignition safety valve 13, pilot burner valve 14, and main burner valve 15, each valve having a valve closure member 16, 46, 34, respectively, loaded by springs 24, 48, 36 towards valve seats 17, 47, 35, and said device also including a control knob 32 connected with a control rod 26 having rotatable therewith a sleeve 30, the knob 32 having "off", "ignition" and "open" positions corresponding to different stages of an ignition cycle, and there being within the housing a solenoid 18 provided with an electromagnet 21 adapted to be energized by a thermo-current produced by a thermo-element heated in the pilot flame. The device operates as follows assuming that it is initially in the "off" condition illustrated in Fig. 1. Gas enters the housing via inlet 101 and is retained in space 51 by valve 13 until knob 32 is pushed towards the housing and is rotated by means of a lug 42 thereon engaging a cam surface 40 on a sleeve 39 fixed to cover-plate 12. Since sleeve 30 is, by means of rod 26, attached to knob 32, it moves in and relates therewith, the inward movement of the sleeves rotating a bell-crank 27 so that an arm 29 thereof forces valve closure member 16 off its seat, and rotation of the sleeve causing a cam-surface 50 thereon to force a rod 49 upwardly thereby displacing valve closure member 46 from its seat. Gas passes via valve 13, space 52 and valve 14 to the pilot burner where it is ignited, the flame heating the thermo-element and producing a thermo-current which energizes magnet 22. Attached to valve stem 19 is an armature plate 20 which is attracted to and retained by magnet 22 after it has been lifted theretowards by crank-arm 29. The knob is now pulled from cover-plate 12 and rotated in the opposite direction, this movement causing rod 26 to pull valve closure member 34 away from its seat and allow gas to pass to the main burner to be ignited by the pilot burner. If the knob is now returned to its initial "off" position the supply of gas to the pilot and main burners is cut off since closure members 34 and 46 enter their seats. The closure member of valve 13 will however remain open during the time the thermo-element remains hot and during this time an arm 55 of the bell-crank enters a slot in sleeve 30 preventing a new ignition cycle from being started since it will not be possible to turn knob 32. Only when the thermo-element has cooled and there is no thermo-current will the armature plate be released by the magnet 22, thus causing closure member to reseat itself and rotate the bell-crank by means of arm 29. This rotation will lift bell-crank arm 55 from the slot in sleeve 30 and allow a new ignition cycle to proceed.

Title: Device for placing pre-wound coils into the stator grooves of dynamo-electric machines
IPC: H02K15/06
Filed: 1977-12-20
Abstract: In order to fit pre-wound coils (9) into the stator slots (8a) of electrical machines, battens (1) are used which consist of two retaining tongues (2) which are connected to one another at one of their ends, are flat, can be spread elastically and are provided with guide strips (3, 3a). The coil sides (7) are held between said retaining tongues (2) and are fitted axially into the stator slots, the guide strips (3, 3a) being guided in a positively-locking manner between the edges of two adjacent tooth heads. Using these battens, it is possible to reduce the number of types of battens, compared with those in the past, by a factor of approximately 10. Furthermore, only two battens, instead of four in the past, are required per operation. <IMAGE>

The temperature of a plasma is measured by measuring at least two pairs of emission or absorption lines, each pair relating to a different chemical element in the plasma and computing the temperature from the measured intensities using the formula: In one embodiment, Fig. 2 (not shown) photomultipliers receiving light from the selected lines charge capacitors and the voltages across these capacitors are fed to an anologue computer to solve the above equation. In another embodiment, Fig. 3 (not shown) capacitors corresponding to each pair of lines are connected to a null indicator and the more charged capacitor of one pair is allowed to discharge to the level of the less charged whilst a constant speed motor drives a carriage along a scale. This is repeated for the other pair of capacitors whilst the motor drives in the opposite direction. The scale is calibrated in temperatures.
