Title: Air traffic control system
Inventor: VELDKAMP JEAN HERMAN
IPC: G05D1/10
Filed: 1956-08-16
Abstract: 869,464. Aircraft control systems. HOLLANDSE SIGNAALAPPARATEN N.V. Aug. 16, 1957 [Aug. 16, 1956; July 1, 1957], Nos. 25096/56 and 20683/57. Drawings to Specification. Class 118. A time-of-arrival computer for use as part of an airport control system calculates E.T.A.'s from external data fed into the machine, e.g. in teleprinter code and relating to aircraft type, call sign, departure airport, time of departure, approach route and wind conditions and from internal data in memory systems and relating to the performance of each type of aircraft, route distances and approach route distances. It compares these times with other E.T.A.'s registered in a memory system and determines whether and by how much an aircraft must be delayed or accelerated to maintain suitable separation between succeeding landing and/or take-off operations. When the aircraft is within radar range of the airport more accurate data is available and a corrected E.T.A. is calculated, checked for separation interval as above registered in the memory system in place of the first calculated time. A display system including a display board and a display memory, exhibits the aircraft data to the controller. The Computer.-This may be digital or analogue and is conventional, digital computer details being disclosed, including a magnetic drum memory system and data deriving networks. The information fed into the computer may be in teleprinter code and relevant information is passed out of the system in this code to other control-points. The display memory is a magnetic drum memory with a comparison system to allow corrected information relating to an aircraft to replace the information already in the memory. Display.-The display panel consists of a series of information lines, each line made up of display elements each relating to one item of information, the display elements relating to the same item being in the same column. The display elements comprise an endless belt having a series of symbols, one of which is visible through an aperture, and each belt has a zeroing electric contact for automatic resetting before new information is to be displayed. Stepping pawls drive the display units when both the appropriate column and line selectors are actuated, a common driving mechanism being used. The line selector is in the form of a lift and the column selectors are a series of selecting magnets. Normally the lift " homes " on an unoccupied line under control of the drum memory but is positioned to the appropriate line when information relating to an aircraft already represented on the board is received and this displayed information is suitably amended by the corrected computer results.

Title: Improvements in or relating to protective clothing and the like
Inventor: MARSDEN JOHN EDWIN
IPC: D06N3/06
Filed: 1958-08-08
Abstract: Protective clothing is made by applying to one side of a fabric a coating of a substance which can be converted by gelling, curing or the like to a durable solid, the nature of the substance and its manner of application being such that there is no penetration through the fabric, thereafter applying to the said substance a further substance of such composition and in such a manner that it modified the composition and rheological properties of at least the outer layers of the first substance so that more of it can be drained off than would otherwise be possible, draining by the desired amount, and converting the coating to a solid without penetration through the fabric.  The fabric may be for example a pre-shaped glove lining and be supported on a former, and the substances may be applied by dipping.  The first substance may be a suitably plasticized polymer composition, and the further substance may contain the same composition together with more plasticizer, or consist wholly of a plasticizer or solvent; it may contain grains of solid material, to provide a rough coating to the finished article.  In tests, knitted glove liners are mounted on formers and coated by dipping with a liquid mix containing polyvinyl chloride powder plasticizers, stabilizers and pigment, drained, and dipped in the same mix with added plasticizer, with or without additions of "Geon" (Registered Trade Mark) 202 polymer or silica sand, or in plasticizer alone, or in toluene, again drained and cured.

Title: Improvements in or relating to gate-operating mechanism for lift systems
IPC: B66B13/14
Filed: 1937-09-20
Abstract: 491,688. Operating lift cages and doors. BERNAERTS, G. H., and BOUDEWIJNS, F. A. Sept. 20, 1937, No. 25493. [Class 78 (iii)] A lift system of the push-button type comprising a landing floor selector, and a control device which includes an electromagnetic reversing element for actuating the cage and landing floor gates by means of a motor on the cage, is characterized by the provision in the wiring of slide contacts mounted on the gate of the cage and actuated by that gate, and fixed contacts controlled by the gates at the landings, the wiring further being arranged for making the circuits required for the closing of the gates, the working of the lift, and the opening of the gates by the actuation of a single pushbutton either on the cage or at a landing. A threaded shaft D, Fig. 3, driven in either direction by belt gearing H, is mounted on the cage and is engaged by a half nut B mounted in a sleeve A. The latter carries slide contacts C which move over conductors 17, 18. The sleeve is connected to the collapsible cage and landing gates, the connection with the latter gate being effected by the engagement of a roller mounted thereon with the channel member E. If the cage is stationary at a landing with the cage and landing gates open, on depression of a call button 6 current passes through the fuse block 1, stopping button on the cage, time relay switch 3, depressed call button, the corresponding coil of the landing floor selector 7, 9, a registering coil 10, relay 12 and coil 14. The energization of the relay 12 causes the armature 13 to complete a circuit which allows current to pass through the coil 15 to the conductor 18, contact 19, and doublepole interrupter 20. The coil 15 actuates a reversing switch which starts the motor in the direction to close the gates. When the gates are closed, the circuit is broken by the opening of the contact 19, the coil 15 is de-energized, and the motor is stopped. At the same time a circuit is completed which allows current to pass through one of the relays 11, one of the coils of the reversing switch 23, the double-pole switch 24, and a gate contact 25. The cage moves and continues to do so until the current supplying brush of the selector 9 arrives at its dead centre. When the cage gate is unlocked, one of the unlocking contacts 22 is closed and current passes through the interrupters 21 of the reversing switch, the doublepole switch 20, conductors 17 and coil 16. As soon as the gates are opened, the circuit is broken at the conductors 17, and the motor actuating the gates is stopped. If there is an obstruction which prevents the closure of the gates, the contact 19 is opened and the coil 15 de-energized, thus stopping the closing movement.

Title: Exposure control system
IPC: G03B7/16
Filed: 1974-06-10
Abstract: 1450633 Cameras POLAROID CORP 10 June 1974 [5 July 1973] 25631/74 Heading G2 A A camera, when used for flash photography, has its exposure aperture and exposure time set in dependence on the focusing of the lens such that, at predetermined intermediate subject distances (typically around 4 feet) the exposure time lasts for most of the flash illumination interval and, for a given subject, is larger than the exposure times at slightly greater and slightly smaller distances. As shown, shutter-diaphragm blades 24, 26 open to an extent dependant on a follow-focus arrangement Figs. 3, 4, 5 (not shown), whereby apertures 36, 38 define on exposure aperture dependant on subject distances and apertures 56, 58 define a photo-cell aperture dependant on subject distance to control an exposure time determining light integrating unit; apertures 56, 58 being shaped to provide the required exposure time control at subject distances around 4 feet. It is stated that such control is necessary because at intermediate subject distances neither the subject nor the background dominates the exposure and the integrating unit tends to produce erroneous exposure times. By utilizing most of the flash illumination interval, the effect of such errors is reduced.
