Patent GB-2037400-A (GB)
Title: Rollers
IPC: B65H23/02
Filed: 1979-10-25
Abstract: A roller has one end arranged to impart precessional motion to the roller in order to impart transverse motion to a web of material carried by the roller, the end of the roller having a stub shaft 9 which can be displaced from the roller axis 6 to any selected eccentric position. The stub shaft is mounted on a disc 7 rotatable about an axis 5 in a cover 3 by a worm wheel 11 in mesh with and rotatable by a worm 16. The worm 16 is fixed on a diametral shaft 17 at one outer end of which is fixed a pinion 15. The latter is in engagement with a toothed rim 14 of an externally milled adjusting ring 13 rotatably mounted by a ball bearing device 12 on the periphery of the cover 3. When the ring 13 is manually turned, the worm wheel 11 turns the disc 7 by means of a pin and the position of the stub shaft 9 is thereby changed in relation to the roller axis 6.   <IMAGE>

Abstract: A high voltage, electrical blade-type single-pole disconnect switch is provided which has an especially designed clip or jaw end for maintaining electrical contact between a bifurcated switch blade (16) and adjacent switch terminal (14) even under very high momentary loads. The switch blade is formed of a pair of elongated, laterally spaced, deflectable metallic blade halves (52, 54) which engage, and are deflected laterally by, the terminal contact (14) when the switch is closed; proper blade-terminal contact pressure is maintained by a tension bolt, sleeve spacer and belleville washer arrangement (66, 68, 70, 72, 74) located adjacent the free end of the blade. The releasable latch (76) for the blade is pivoted thereto at a point closer to the marginal end of the blade (16) than the engagement between the latch and a stationary latching clip (84), such that the latch is pivoted closed into firmer engagement with the clip under the influence of normal electromagnetic forces which tend to pivot the blade to its open position. <IMAGE>

Title: Selective vaporization process and dynamic control thereof
IPC: C10G25/09
Filed: 1981-04-28
Abstract: Whole crude and residual fractions from distillation of petroleum and like feed stocks are subjected to selective vaporization to prepare heavy fractions of reduced Conradson Carbon and/or metals content for use as feedstock for fluid catalytic cracking by short-term, high temperature riser contact with a substantially inert solid contact material of low surface area in a selective vaporization zone. High boiling point components of the charge which are of high Conradson Carbon number and/or high metal content remains on the contact material as a combustible deposit which is then burned off in a combustion zone whereby the contact material is heated to a high temperature for return to the selective vaporization zone to supply the heat required therein. The system is dynamically controlled for fuel supply in the combustion zone by the lower hydrogen content, least valuable components of the feed. That control is exercised by controlling the temperature of the selective vaporization zone to about the minimum value which will maintain a predetermined desired temperature in the combustion zone. The temperature of the selective vaporization zone is controlled by regulating the rate of recycle of the heated contact material to the vaporization zone.

Title: Apparatus for determining position of piston in cylinder
Inventor: BATHORY BELA ISTVAN
IPC: B21B38/10
Filed: 1983-02-28
Abstract: A combination for accurately determining the position of the movable part of a piston-cylinder device relative to the fixed part includes a long stroke position transducer 17 movable in the operating direction of the device; a structure 23 movable with the piston- cylinder device and which has a part 25b extending in the operating direction; two position transducers 30 positioned side-by-side and of which the direction of movement of a respective movable part is normal to the operating direction.

Patent GB-2118387-A (GB)
Title: Disc player
Inventor: MEHROTRA GOPI NATH
IPC: H03G3/34
Filed: 1983-03-28
Abstract: An audio EM signal recovered from a disc record is demodulated to baseband by an EM demodulator 44, 46, the baseband signal tending to exhibit a low frequency transient disturbance audible upon a change in the state of the player power control switch 10. The baseband signal is coupled to a player output terminal 70, 72 via a path including a track-hold circuit 50, 52 and a variable gain amplifier 80, 82. The track- hold circuit is normally conditioned to track the baseband signal but assumes its hold operating mode when frequency excursions of the EM signal exceed predetermined limits to suppress record defects such as ticks and pops. The variable gain amplifier functions as an expander for baseband signals of compressed form and as a constant gain amplifier for baseband signals of non- compressed form. The player output signal is muted and the transient disturbance is suppressed by a control circuit 56, 58, 60, 84, 86, 88, D1 which places the track-hold circuit in its hold mode and simultaneously conditions the amplifier to function as an attenuator during selected player operating modes. <IMAGE>
