Title: Systems and methods for detecting faults in solenoid utilization systems
IPC: G01R31/72
Filed: 1976-01-19
Abstract: 1499254 Testing performance of electrical apparatus BURROUGHS CORP 19 Jan 1976 [18 Feb 1975] 01928/76 Heading G1U In monitoring the performance of a solenoid, its instant of "seating", i.e. when the armature is fully drawn into the coil, is determined and compared to acceptable early and late limits. The "seating" is detected by monitoring 65 the current through the solenoid coil as it is subject to an energizing square pulse. The anticipated exponential rise in current through the coil is modified since as the armature moves into the coil, its inductance increases thereby opposing the increase. At a certain point, the rate of increase of inductance has a greater effect than the exponential rise, and the current falls until the armature "seats", when it rises once more. This "cusp" is detected 65 by a differential amplifier connected across a current sensing resistor (109), Fig. 6 (not shown) having differing time constant circuits connected to its two inputs. The system is controlled by logic 69, which in response to an external stimulus 71, provides the energizing pulse to the solenoid drive circuit 59 and coil 53. The logic 69 also derives two enabling signals representing the time periods before and after an acceptable "seating" instant period. Thus coincidence of a cusp detector output 67 with either enabling signal indicates 75 a fault. By push-button operation, Fig. 8 (not shown), the "acceptable" limits can be narrowed, so that a solenoid which is apparently "seating" within the operating tolerances can be tested to see if it is tending to move away from the ideal "seating" instant. The logic circuit 69 is described in detail Fig. 7 (not shown). The solenoid applications referred to are in card-sorting machines, Figs. 2-3 (not shown) or print-hammers, Fig. 4 (not shown).

Title: Industrial trucks
IPC: G05G9/047
Filed: 1961-01-18
Abstract: 915,489. Control of D.C. motors; controllers. YALE & TOWNE MANUFACTURING CO. Jan. 18, 1961 [July 11, 1960], No. 2025/61. Class 38 (3). The speed and direction of an industrial truck having two reversible traction motors are controlled by handle 40 mounted for universal pivoting and actuating spring-biased rods 42 associated with controller-portions 36-39. Assuming that the handle is moved to actuate contacts 36-1, 37-1, these contacts first engage dead contacts 36-D, 37-D, to prepare the starting circuits of the motors in the forward direction. The contacts 36-1, 37-1 are now interconnected through lead 45, so that, if one of the live contacts 36-L, 37-L, is inadvertently engaged before the other, the motors are energized simultaneously. This prevents erratic movement of the truck. Other combinations of two controller-portions 36-39 may be actuated to effect simultaneous energization of the traction motors whereby the truck may be driven in the direction of its axis or may be pivoted due to rotating of the traction wheels in opposed directions. Each motor is associated with two reversing relays, and with two relays for regulating armature resistance, these relays being controlled from the contacts of sections 36-39.

Filed: 1946-01-02
Abstract: 606,927. Directive radio systems. WESTERN ELECTRIC CO., Inc. Jan. 22, 1946, No. 2086. Convention date, Jan. 24, 1945. [Class 40 (vii)] A highly directive aerial system comprises a pair of cylindrical-parabolic reflectors facing each other and having mutually perpendicular focal lines, an aerial element being coincident with one of the focal lines. Figs. 1 and 3 and Fig. 2 (not shown) illustrate such a system in which an aerial 10 comprising an extension of the central conductor of the coaxial transmission line 2 is aligned with the focal line 5 of an auxiliary horizontal cheese reflector 3 comprising a short vertical parabolic cylinder with end plates 7 and 8 spaced apart a distance D less than #/2 and having a rectangular aperture 9 which radiates into the main reflector 13 comprising a horizontal parabolic cylinder, the focal line of which, 15, is coincident with and equal in length to the horizontal dimension of the rectangular aperture 9. The auxiliary and main reflectors may be regarded as controlling the horizontal and vertical directivity respectively and the angular aperture # of the main reflector is adjusted in relation to the vertical dimension D of the aperture 9 to produce a pencil beam with a plane wave front. In a modification, Fig. 4, the system is cut in two by a horizontal plane reflector 25 and only the upper half is utilized. In this case the vertical directivity is reduced and the upper half of the vertical polar diagram follows an approximate cosecant distribution which is the ideal shape for a radar system used for the detection of long-range aircraft. In a further modification of this type, Figs. 5 and 7 and Fig. 6 (not shown), the auxiliary reflector 3 is inclined at an angle to the horizontal and is mounted in a wooden framework 43 with horizontal reflecting platforms 46 and 47. The focus 38 of the auxiliary reflector is near its aperture and the aerial element mounted adjacent the focus comprises a polystyrene plug 50 fed by a wave-guide 49, the surface of the plug facing the main reflector 13 being shielded by a brass member 51. The whole structure is made of wood and the reflecting surfaces of the parabolic cylinders and of the platforms 46 and 47 are covered with copper foil. Suitable dimensions are given for an operating wavelength of 9.8 cms. and Figs. 8 and 9 (not shown) illustrate the horizontal and vertical polar diagrams produced by such a system.
