Title: Wheel slip protection device
IPC: B60L3/10
Filed: 1967-10-23
Abstract: Also in Division H2 In a traction system, excessive wheel-slip is prevented by reducing the tractive effort in response to a signal having variable and constant components which are developed from an axledriven tachometer generator 1. The output of the generator is rectified, smoothed, and differentiated to provide a deceleration signal ar which is applied to flip-flop circuits 8, 9, associated with an OR- gate 10. When the decleration signal is between a minimum and mean value, the polarity of terminal S', of circuit 8 is such that diode 13 conducts, this Diode 20 conducts when the deceleration of the wheel reaches a maximum value so that capacitor 15 discharges through resistor 21, the output voltage of the amplifier 16 decreasing. The rate of discharge is changed when diode 24 conducts, and diode being connected to Zener diode 11 and resist- or 12. Capacitor 15 is charged through resistor 14 so that amplifier 16 generates an increasing correction-signal component delta JS1. When the signal ar exceeds the mean value, the terminal S' changes polarity, diode 13 is blocked, and the output of amplifier 16 remains constant for a period. the capacitor 15 discharges through high ohmic resistor 25 so that the output voltage of the amplifier 16 falls slowly and linearly with time. At the commencement of wheel-spin, capacitor 30 is charged rapidly through diode 28 so that diode 29 conducts to provide correction-signal component delta JS2. This component is held constant for an extended period until the polarity of terminal S of the gate 10 changes sign and the capacitor 30 is discharged through resistor 26. The traction motor 38 is supplied through rectifier bridge 36, a reference signal JC for the motor current being derived from potentiometer 31 through a non-linear limiting element 32. The anti-wheel spin device 33 provides signal JCS representing the sum of signals delta JS1 and delta JS2. The resultant signal JCr is compared with current signal J to control the rectifier 36. The anti-slip device may be modified to control regenerative braking of the vehicle.

Title: Calendering roll
IPC: B30B3/00
Filed: 1967-11-29
Abstract: A hollow roll, e.g. for rolling, calendering, embossing, glazing, coating, printing, drying, or grinding, comprises a rotatable cylindrical shell 1, a fixed or rotatable shaft 2 substantially on the axis of rotation of the shell, and, between the shaft and the shell, inflatable annular chambers 6a-6n or other resilient means capable of exerting a uniform radial pressure on the shell at any given radial plane connected to external pressure control means (not shown). The chamber pressures are controlled to maintain a predetermined axial pressure distribution along the nip between the hollow roll and a second roll 3. In Fig. 4, each annular chamber consists of a pneumatic tyre on a wheel 5a-5n the hub 12a-12n of which is secured to the shaft 2. Separate lines 9a-9n connect the tyres to the pressure control means. Shaft 2 is driven via a coupling 8, and may be bent longitudinally by forces f1, f2 to assist in obtaining the required axial pressure distribution at the nip. The tyres may be inflated and deflated to engage and disengage the drive to the shell 1. In Fig. 6 (not shown), the shaft (2) is not rotatable and the wheels are supported thereon by bearings (14a-14n). In Fig. 7 (not shown), a curved shaft (2) carrying bearings (14a-14n) for the wheels is rotatably adjustable to adjust the axial pressure distribution at the nip. In Fig. 8 (not shown), the wheels are omitted, the tyres (6a-6n) being supported directly on a large diameter rotatable shaft (2). The shell 1 may be a plain tube of steel, bronze, aluminium alloy, or plastics, and may have a resilient rubber or plastics lining. Alternatively, Fig. 9, for greater resilience, the shell may be a longitudinally slotted tube covered with a flexible sleeve (17), (Fig. 10, not shown) of rubber, plastics, or thin steel or other metal. In Figs. 11-14 (not shown), the roll is mounted inside a hollow cylindrical roll to apply the latter against a counter roll. In Fig. 11 the roll (102) has a diameter almost equal to the internal diameter of the hollow roll (100) and is rotatable. In Fig. 12 a stationary roll (112) acts via a needle bearing (117) against the internal surface of a hollow roll (111). In Fig. 13 a small rotatable roll (122) acts on the internal wall of a hollow roll (121), and in Fig. 14 a similar small roll (132) is carried at one vertex of a triangular frame (135), loose rollers (136) at the other two vertices also engaging the internal surface of a hollow roll (131).

Title: Induction logging methods and apparatus using more than one phase component of the received signal
IPC: G01V3/30
Filed: 1970-12-28
Abstract: In accordance with an illustrative embodiment of the present invention, methods and apparatus are disclosed for measuring the average conductivity and heterogeneity of formations surrounding a borehole. To accomplish this, certain phase components of the electrical signal produced by an induction logging tool are measured and combined in accordance with given mathematical relationships to produce indications of the average conductivity and heterogeneity of a formation. Moreover, the average conductivity and heterogeneity indications can in turn be combined to give indications of the conductivity of different radial regions of the formation under investigation. Additionally, to measure these phase components, a technique is disclosed for eliminating the mutual coupling between the transmitter and receiver coils of an induction logging tool. In this technique, the transmitter coil(s) is excited at two different frequencies and the mutual coupling component of the voltage induced in the receiver coil(s) at the lower frequency is used to cancel out the mutual coupling component at the higher frequency. The phase components used for computational purposes are then measured at the higher frequency.

Title: Toy phonograph with automatic pickup arm return means
IPC: G11B33/06
Filed: 1976-05-11
Abstract: For automatically returning a pickup arm to a predetermined starting position on the perimeter of a record disc on a motor-driven turntable upon completion of playback, a drive gear is mounted on a turntable shaft for simultaneous rotation with the turntable. A driven gear, integrally formed with a cam, is mounted on a pivotal arm for movement into and out of engagement with the drive gear. When the pickup arm travels to a terminal position on the record discs, during playback, the driven gear is thereby urged into engagement with the drive gear and is, thus, set in rotation with the cam. The rotating cam causes the pickup arm to be lifted off the record disc and, then, to be spring returned from the terminal to the starting position. The record disc used herein is of the type having a plurality of grooves formed therein in the shape of nested spirals, for successive or random playback.
