Title: Improvements in control systems for hoist motions of electric cranes and the like
IPC: B66C15/00
Filed: 1943-10-22
Abstract: 571,447. Control of motors. BRITISH THOMSON-HOUSTON CO., Ltd., and POOL, W. J. Oct. 22, 1943, No. 17414. [Class 38 (iii)] Safety arrangements :-In a control system for an electric hoist, or the like, of a type in which speed adjustment of the main motor is effected by a pilot motor, a time delay element is provided which commences to time immediately the controller is returned to its " off " position and which operates in parallel with the pilot motor in such a manner as to cut off power from the main motor and apply the brake thereto when either the speed of the main motor has been reduced to a predetermined value or a certain time delay has expired. Normally the disconnection of the motor and the application of the brake is under the control of the pilot motor, the time delay element merely providing a safeguard in the event of failure of control by the pilot motor. In the system shown, movement of controller C from the " off " position in the "hoist" direction energizes a forward contactor H over low speed interlock S1 and contact b of a time delay relay T. When H picks up it connects the motor to the mains, establishes a holding circuit for itself, energizes BR which releases the controller contacts and interlock on H in the coil circuit. If T fails to pick up when the motor is started, the motor is disconnected from the line and the brake applied immediately the controller returns to the " off " position. If T fails to drop out for any reason the connection of contact b provides that the motor cannot be. restarted.

Title: Improvements in or relating to aircraft provided with a winch supporting a trailing aerial
IPC: B66D1/12
Filed: 1934-06-18
Abstract: 440,104. Winches for aircraft. PLESSEY CO., Ltd., HODGSON, A. D., and WILLIAMS, G. R., Vicarage Lane, Ilford, Essex. June 18, 1934, No. 17999. [Class 78 (v)] The drum of an electrically-operated winch for the trailing aerial on aircraft is provided with an electromagnetic brake operable during paying-out. The winch comprises a bracket 3 carrying a motor 4 and a shaft 2 on which the drum 1 is mounted. One ring 5 of internal teeth on the drum is driven by a pinion 13 on the motor shaft, while a second ring 15 operates screw- and-nut overwinding-preventing gear 7, 8. During winding-in, spring pawls 10 on the drum override the teeth on a ratchet wheel 9 attached to the brake drum 18, so that the latter prevents running- back, and holds the aerial in its fully woundin position after the power has been cut off by the gear 7, 8. To pay out by gravity, the brake arm 6 is raised directly by hand or indirectly through remote control to release the brake shoe 19, this operation also closing contacts 21 to connect up the field-circuit of the motor to a power supply through a suitable resistance, and short-circuiting the armature through a load resistance, thus connecting up the motor as a generator to act as a brake during paying-out. At the limit of paying-out, the member 8 rocks the lever 12 and thus pulls the link 15 to re-set the brake. The member 8 also re-connects the motor for use in winding-in. The brake drum may be replaced by electromagnetic control of the pawls 10, or by a magnetic clutch ; the overwinding-preventing gear can be operated directly by beads on the aerial wire ; and indicators may be fitted showing the position of the aerial wire and recording its absence if lost in flight. A fair-lead pulley also may be utilized to cut off the motor if the aerial is obstructed during flight.

Class 123(1) A closure for preventing the escape of liquid which may leak past a spring-closed check valve 18 closing the filling and draining opening in the bottom, plate. 12 of a tank which may, for example, be the fuel tank of an aircraft with an underneath refuelling system, consists of a disc 33 provided with apertures 36 and a peripheral rubber-like sealing gasket 21 which engages the lower side 25 of an annular flange 17 defining the tank opening and upon which. the valve 18 bears. The disc 33 is brazed to an extensible bellows 31 the lower end of which is brazed to a circular plate 30 secured to a central pin 38 which protrudes through a central clearance hole in the disc 33, the plate 30 and the disc being held apart by a spring 47. Rotably mounted on the lower end of the pin 38 is an attaching cap 43 provided with bayonet lugs 52 engagable over bayonet lugs 22 on a skirt depending from the flange 17. When the closure device is in position the cap 43 is flush with the bottom plate 12 and the bellows is slightly compressed with the gasket 21 abutting the sealing surface 25 on the underside of the flange 17. If leakage occurs past the valve 18, the bellows fills with liquid and, since its outer diameter is greater than that of the contact line between the gasket 21 and seat 25. the liquid pressure urges the gasket into tighter sealing engagement with the seat to prevent escape of liquid.

Title: Interrupt computer system
IPC: H04L5/00

Abstract: 1,099,575. Priority interrupt system. COMPUTING DEVICES OF CANADA Ltd. April 26, 1966 [March 29, 1966], No. 18290/66. Heading G4A. In a priority interrupt system, each of a plurality of peripheral devices connected to a central data receiving apparatus by a common connection means includes a priority signal generating means for providing on said common connection means-when stimulated by a signal from said central apparatus-a priority signal indicating that access to said central apparatus is required together with monitoring and inhibiting means for monitoring the signals on said common connection means and for inhibiting the signal generating means of that device when a higher priority signal is detected on said common connection means. A simple serial mode system is illustrated in Figs. 1 and 2 (not shown), wherein the priority signals comprise a sequence of pulses of decreasing significance on a single transmission line, the monitoring means comprises a comparator and the inhibiting means a gate. In a parallel mode system (Fig. 3- which shows part of the circuitry at a single peripheral device) the common connection means comprises a data bus consisting of seven balanced-pair transmission lines A-G, lines B-G for carrying the priority signals and line A for carrying the priority signal generating means initiating signal. The monitoring and inhibiting means is divided into six similar sections 51-56, each with an input 60-65 for receiving one bit of the priority signal (when access to the central apparatus is desired by that device). Operation of the circuitry (which is described in detail in the Specification) is such that the initiating pulse from section 50 is passed from section to section and arrives at terminal 127 only if the code at inputs 60-65 represents a higher priority than any other code on lines B-G. A signal at terminal 127 thus identifies the peripheral device with the highest priority. Once a code is found to be of lower priority than a code on lines B-G (taking the lists 60-65 in descending order of significance) all subsequent bits (i.e. of lower significance) are suppressed.
