Title: Improvements in or relating to safe-load indicators for cranes
IPC: B66C23/90
Filed: 1949-01-03
Abstract: 656,083. Safe load indicators for cranes. HAUSSER, P. C. G., JAMES, R...T., and AITKEN, R. L. Jan. 3, 1949, No. 112. [Class 78 (iv)] In a safe load indicator for a crane, a cable 11 tensioned according to the load passes from a pulley at the end of the jib over pulleys 12, 13 to an anchorage. The pulleys 12, 13 are mounted in carriers 9, 14 of which the former is pivoted at 17 to a fixed mast 10 of the crane while the latter 14 is pivoted at 18 to the former. Pivotal movement together of the carriers 9, 14 is resisted by the yielding member 19 of an indicating mechanism, while upward pivotal movement of the device as a whole about pivot 17 is limited by an abutment 30 on the carrier 9 which engages the mast 10. Downward pivotal movement of the device about the pivot 17 is restrained by the abutment of the spindle' 29 of pulley 13 on a pair of links 21 pivoted at 22 on a member 19 secured to the carrier 9 and abutting at 24 on the mast 10. Thus when the jib lies above a predetermined angle, the carrier 14 is pressed upwardly towards the carrier 9 by the cable 11 and a force which is independent of the elevation of the jib is applied to the member 19. When, however, the jib is at a lower elevation, the cable 11 applies to the pulley 12 a force tending to turn it downwardly about the pivot 17 and this force is dependent upon the angle at which the cable 11 meets the pulley 12; the resultant force on the member 19 depends also upon the position of the abutment 24. To enable the characteristics of the device to be altered, the abutment 24 is mounted on a plate 26 slidable along the links 21 and secured in any desired position by a bolt 27. In an alternative construction the links 21 are pivoted at their lower ends to a clevis bolt projecting from the mast 10, the abutment 24 being omitted, and, instead of the spindle 29, an abutment capable of sliding adjustment on the carrier 14 bears against the edges of the links 21. In this construction the abutment 30 is replaced by a stop which limits the pivotal movement of the links 21 relatively to the carrier 9.

Title: A stepping device
IPC: H02K7/065
Filed: 1960-01-04
Abstract: 883,979. Reciprocating motors. LEDEX Inc. Jan. 4, 1960 [Jan. 12, 1959], No. 196/60. Class 35. In a stepping motor having balls acting on inclined planes to convert reciprocation of an armature into rotation, springs bias the balls to one end of the inclined planes and the position of the balls controls an interrupter in the energizing coil circuit. As shown, the armature 32 on a shaft 30 has attached to it a member 38 having inclined, arcuate, recesses 42 in its underside between which and a flat, stationary race 36 the balls may run. The balls are located by recesses 48 in a cage 46 which also comprises a member 52 having lugs 62 for springs 66 (Fig. 2, not shown); the opposite ends of the springs, which are located in spaces 68 in the cage, engage further lugs 64 on the member 38. Upon energization of the coil 20 the armature 32 is attracted to a core 12 and the balls are forced up the inclined recesses, causing the member 38 and hence the armature and its shaft to rotate one step. The ball cage will then have rotated half a step and the springs will be compressed. Upon de-energization, the armature shaft is held stationary, by the load or an indented disc 70, and the springs advance the ball cage a further half-step, thus returning the balls to the first end of the inclines and forcing the armature away from the core. Repetition of the cycle causes further rotation of the shaft 30 in the same direction. Driven by projections 84 on cage member 52 is a wafer switch 86 having one fixed contact for each step and one rotating contact 92. When the latter reaches a " live " fixed contact another step is initiated; thus, if all the fixed contacts are energized continuous rotation results, or the device may be made to stop at a selected position by energizing all but one, e.g. by a separate wafer switch having one less rotary contacts than fixed (Fig. 5, not shown). In an alternative arrangement (Figs. 7 and 8, not shown), for continuous operation only, the wafer switch is replaced by a single pair of contacts operated by cam projections on the ball cage, and in a further alternative (Fig. 9, not shown) a microswitch in the casing of the device is acted upon by a separate cam ring, e.g. of nylon, driven by the ball cage. In a final arrangement (Figs. 10 and 11, not shown) the inclined recesses are formed on the stationary ball race, the rotating one being flat, and cam projections on the ball cage operate a two-position lever switch.

Patent GB-1377121-A (GB)
Title: Charge coupled circuits
IPC: H01L21/00
Filed: 1972-01-05
Abstract: 1377121 Charge coupled devices RCA CORPORATION 5 Jan 1972 [14 Jan 1971] 387/72 Heading H1K In a charge coupled device charge is injected from a source region under control of a gate electrode, the source being reverse biased relative to the substrate. As shown, Fig. 4, the substrate 10 is of N type Si and is biased to + 5V while the source region S1 is of P+ type conductivity produced by diffusion of B and is biased to - 5V relative to ground (i.e. - 10V relative to the substrate). A plurality of storage electrodes 14-1, 14-2 overlying a thin SiO 2  layer are connected to a multi-phase power supply to cause charge to shift from one storage location to the next. A control electrode 14-0 is provided between the source S1 and the first storage electrode 14-1. When suitably timed pulses are applied to the control and first storage electrodes charge carriers flow from the source S 1 to the potential well below the storage electrode until the surface potential below the storage electrode is approximately equal to that of the source. The potential well is therefore partially filled, the level depending only on the potentials applied to the source and storage electrode. If the control electrode is held at OV no charge is injected into the potential well and this represents a "0" state while the "1" state is represented by the presence of stored charge in the potential well. The bias on the substrate inverts the surface of the substrate beneath the electrodes thus reducing surface leakage due to surface states at the Si-SiO 2  interface. In a modification, the source is given a bias of - 15V on which may be superimposed a positive going 10V pulse so that when this pulse is present and negative pulses are applied to the control and first storage electrodes charge carriers are injected into the first potential well as before but if the source voltage pulse is absent no charge can be injected even when the control voltage is present, the source in fact acting as a drain to remove any residual charge from the potential well. Logic functions can be performed using input arrangements of this type. An AND function may be provided by utilizing the source and control pulses or by arranging two input control electrodes in series. An OR function may be provided by arranging a plurality of sources in parallel. Stored charge levels of different magnitudes may be utilized to represent the "0" and "1" states, the charge level injected being determined by the source potential. The charge injection arrangement may form part of a transfer arrangement between shift registers. The specification also describes arrangements of the storage electrodes and bias supplies to permit two phase operation, and the method of fabrication.
