Title: Improvements in or relating to blank feeding and holding mechanism for nut tapping and like machines
IPC: B23G1/20
Filed: 1926-05-04
Abstract: 259,177. Arnold, P., Guyot, G. A., and Perrin, G. M. Sept. 29, 1925, [Convention date]. Tapping nuts.-A blank feeding and holding mechanism for nuttapping and like machines in which the rotary tool spindle has an axial reciprocating movement, comprises a feeding drum having laterally projecting resilient members which position the blanks for the tapping operation. The spindle 32 carries at each end a tap 26, 44, operating in conjunction with a pair of blank delivering mechanisms so that while one blank is being tapped, the second tool is being withdrawn from another blank. The hoppers 2<a>. 2<b> comprise a frame 5 supporting a shaft 6 which is driven by a pulley 12 and carries a drum 7 surrounded by a hoop 8. The inner periphery of the drum is adjusted by spacers 19 at a distance slightly greater than the thickness of the nuts to be tapped from the adjacent face of the frame and is provided with a number of spring-pressed balls 10. The blanks are introduced into the shoot 18 and the rotation of the drum causes them to be fed between inclined guide plates 21 into a vertical guide 13 which is closed by a front plate 23. The blanks then pass into a pocket 24 in a slide 14 fed by a lever 15 which is moved forward by a spring 49 and positively returned by a cam 25 on a shaft 4. The lever is returned before the tap has finished working and on withdrawal of the tap, the slide 14 is fully withdrawn by a spring 16 and the finished nut passes through an aperture 28 into a receiver. The spindle 22 carries a fixed friction pulley which by axial movement of the spindle may be driven from either of the oppositely-rotating belt-pulleys 34, 35. A double cam 38, 39 embodying a resilient device, actuates a lever 37 to impart axial movement to the spindle. When the spindle is moved to the right, the tap 26 is rotated in the cutting direction while the opposite tap 44 is withdrawn, these actions being reversed when the spindle is moved to the left.

Title: Multiple Zone Elevator Control System
Inventor: MADISON ROBERT WAYNE
IPC: B66B1/18
Filed: 1967-03-13
Abstract: 1,164,733. Lift control systems. OTIS ELEVATOR CO. 13 March, 1967, No. 11763/67. Heading B8L. In a multicar lift system selector contacts corresponding to each landing are grouped into zones and associated with each group are "assignment switches", one for each car; the arrangement is such that cars distribute themselves into the various zones even in the absence of calls. When a car enters a zone having no car already assigned to it the appropriate switch is actuated to assign that car to that zone, whereby it is responsive to landing calls only within that zone, and will park in that zone, the remaining cars ignoring landing calls within that zone. However, any car can be despatched to any landing in response to signals made within the car ("car calls"). When an assigned car leaves its zone in response to a car call another may take its place. An assigned car, if idle, may also respond to landing calls made in adjacent zones, or the main landing, if they have no car assigned to them. While an assigned car is travelling in response to a car call it will also stop for landing calls, even outside its zone, for journeys in the same direction, or in the opposite direction if it has made its last stop. Each car is powered by a motor generator set, and when a car has remained parked for a predetermined time this is switched off. When a car enters the main landing zone it causes any car already there, with its MG set still running, to leave as an unassigned car; if the MG set has stopped the newly arrived car instead is despatched. Such an unassigned car travels until it reaches an unassigned zone whereupon it is assigned to that zone. During exceptionally heavy down traffic, detected by any known device, when any car reaches the main landing it is despatched to the highest zone. Calls are made by touching cold cathode tubes, the hand capacitance being sufficient to effect switching. When a car parks away from the main landing its doors are not opened. Movement of the cars is initiated by the selector contacts which are swept by a brush contact driven by a separate motor.

Abstract: 1,071,455. Gyromagnetic resonance apparatus. VARIAN ASSOCIATES. March 23, 1965 [April 24, 1964], No. 12321/65. Heading G1N. In a spin decoupling arrangement, for a gyromagnetic apparatus wherein a sample-containing probe 10, Fig. 1 is situated in a polarizing magnetic field H o  provided by magnetic poles 12, and wherein one radio frequency signal from a generator 14 is applied to the probe for orienting a group of atom portions to be observed in the sample, a second r.f. signal is also applied to the probe from a generator 32 to decouple secondary atom portions from the portions to be observed, and both the undesirable tilting of the spin axis of the observed atom portions caused by the second signal and the tendency of the spins of the observed and secondary atom portions to recouple, are obviated by applying to the probe a third r.f. signal from a generator 34. The combined effect of the second and third signals decouples effectively the secondary portions but leaves the observed portions unaffected. A low frequency (e.g. 2 Kc/s) oscillator 16 modulates the polarizing field H o  so that the frequency of the orienting signal from generator 14 (e.g. 60 Mc/s) is effectively regularly swept through the resonant frequency of the atom portions to be observed. A detector in the probe generates an output signal which is amplified at 20, and phase-detected, first at 24 with reference to the orienting signal from generator 14, and then at 28 with reference to the low frequency of oscillator 16, the output of the phase-detector 28 producing on a recorder 30 the spectral trace of the atom portions under test. The frequencies of the second and third r.f. signal generators 32, 34 may be, for example, 60 Mc Œ 100 c/s respectively. In a second embodiment Fig. 3 (not shown) a substantially similar system is used, but in this case, the second and third r.f. generators (40, 44) modulate the polarizing field (produced by oscillator 36) and produce with the orienting r.f. signal (from 14) two sideband frequencies which effect the required decoupling and tilt compensation.
