Abstract: 874,455. Door operating appliances; door holders. KING Ltd., G. W. March 9, 1960 [Jan. 29, 1959], No. 3206/59. Classes 44 and 65(1). A vertically sliding door controlled by at least two independently operated hoist units coupled to the door at spaced points along its length has means to automatically control the speeds of the hoist units so that the door remains level during its movement. Each unit includes an electromagnetic coupling the output of which is controlled by a magslip device, one magslip being mounted at each side of the door opening and having a pinion on its drive shaft in mesh with a vertical rack on the door. A set of switches, one associated with each unit, may be fixed at the bottom of the door for actuation by contact with the floor. Forcing doors to their seatings. The lower end of each vertical edge of the door carries angled strips 35, 36 (Fig. 5) projecting therefrom which, when the door reaches its lowermost position, engage rollers 40, 41 freely pivoted at the ends of a double-armed lever 37 pivoted to the door frame on a vertically spring-loaded pivot 38. The door is thereby forced towards its seating position (shown in chain dotted lines). The upper edge of the door carries a number of hooks 43 (Fig. 6) pivoted to the door at 44 which, when the door approaches its lowermost position, engage fixed pins 49 on the door frame. The weight of the door tends to swing the pivots 44 fowards a line vertically below the pins 49 and thus forces the upper part of the door towards its seating. Safety devices. A safety device is provided at each side of the door to prevent it from falling freely e.g. on failure of the hoist cables. A T- section rail 21 (Fig. 4) mounted on the edge of the door slides in a slot 20 in a fixed block 19 and a pair of gripper members 25, 26 pivoted in part-circular recesses in the block are geared together by spur wheels 29, 30 and are normally held inoperative by a solenoid 34. In the event of a failure the solenoid is de-energized and the members 25, 26 rotate to bring toothed projections 27, 28 thereon into engagement with the rail 21. The members may be pivoted on shear pins so that when the safety device operates they seat in the part circular recesses and frictional resistance to rotation is thereby provided.

Abstract: 639,087. Electric motors. KING, Ltd., G. W., VAUXHALL MOTORS, Ltd., and GILBERT, S. Feb. 9, 1948, No. 3751. [Class 35] In a control system for an electric motor wherein the motor is so mounted that the stator is capable of a pivotal or angular movement but has means associated therewith adapted to apply a predetermined torque effect thereto so that under normal conditions of operation pivotal or angular movement thereof will be prevented, but in the event of an overload such movement will be allowed and utilized to effect operation of a switch controlling the supply of power to the motor, electromagnetic means are provided which are operative on starting of the motor to supplement the torque effect applied to the stator and thereby effectively to prevent angular movement of the latter during such starting period, said means being adapted to be cut off automatically as soon as normal running of the motor is attained. As shown, an electric motor 10 drives a pulley 11 and belt 12 which is coupled to a driving sprocket through a gear train, the driving sprocket forming part of a conveyer system. In order to allow for or to take up variations in tension on the driving chain of the system, the motor and associated gear are mounted on a platform 13, the position of which is adjustable relatively to a stationary supporting structure. The platform 13 may be controlled by means of a counterweight or by adjusting-screws 13<1>. The motor is mounted in a cradle 15 which is carried on supporting brackets 16 fixed to the platform 13. The members 10 and 15 are adapted to pivot together about the longitudinal axis of the motor. An arm 17, mounting an adjustable counterweight 18, is fixed to the cradle 15. Under normal conditions the arm 17 is positioned to close a contact switch 19. In the event of an overload upon the motor the arm 17 is swung away from the switch which opens the supply-circuit. An electromagnet 20 retains the arm 17 in the switch-closure position, being energized during the early part of the motor-starting operation to prevent the arm reacting to the heavy initial torque. The arm 17 may be latched in the cut-out position.

In a similar system (see Fig. 2, not shown) a projection screen is used. In the system illustrated by Fig. 3 both " writing " and " extinction " C.R.T.s 28, 31 respectively are scanned in planposition indicator form and both are intensitymodulated with radar echo signals. Shutters 38, 39 are interposed so that the " writing " and " extinction pictures are projected alternately on to screen 27; a moving target is indicated by a dotted line and stationary targets are displayed less brilliantly or, by so choosing the luminescent material of the screen that its build-up time is longer than the time between excitation and extinction, not at all. The shutter speeds may be varied to give several " writing " cycles for each " extinction " cycle. Appropriate cut-off bias voltages applied to the grids of the C.R.T.s may replace the shutters. Suitable screen materials are quoted.
