Title: Photographic camera,more especially a single lens reflex camera
IPC: G03B7/20
Filed: 1961-07-07
Abstract: 969, 639. Exposure setting means in photographic cameras. AGFA A. G. July 7, 1961 [July 12, 1960], No. 24739/61. Heading G2A. A photographic camera for use with interchangeable objectives each including a variable aperture diaphragm spring loaded towards one extreme setting position, has an exposure value setting device including a setting member controllable by an exploratory device for the galvanometer of a photo-electric exposure motor and also includes a release member for holding the setting member in an idle position until the exposure value is to be set; the arrangement being such that when an objective is attached to the camera said setting member is spring urged by the objective's diaphragm setting means into contact with the release member so that in movement of the release member the setting member and means follow it until arrested by the exploratory device. In the reflex camera shown the diaphragm blades 6 are pivoted on a fixed plate 4 and a movable plate 9 which is urged by spring 11 in direction a to close the blades. A pin 13 on plate 9 engages a lug 15 on a rotatable control ring 14 which is also engaged by a lug 33 on a shutter setting and release ring 32. The ring 14 is operatively linked through parts 17-24 to a cam 27 which may engage the pointer 30 of a rotatable exposuremeter galvanometer 31. An exposure time setting ring 43 is connected through parts 51-61 to a rotatable member 63. By means of a rotatable knob 68 and scales 70, 71 the galvanometer may be rotated relative to member 63 to account for-film sensitivity and the maximum relative aperture of the objective and is locked by means of pins 69 in this position. When the exposure time setting ring 43 is subsequently rotated the member 63, galvanometer 31 and its needle 30 are rotated by a corresponding amount. When the shutter is released and ring 32 rotates in direction a, plate 9 and hence ring 14 are rotated in the same direction by spring 11 until cam 27 engages the pointer 27 and stops ring 14 and hence plate 9 and a diaphragm opening corresponding to the setting of pointer 30. The diaphragm can be set manually by means of a setting ring 37 with a lug 38 which acts as a stop for ring 14 and when ring 37 is set a cam 39 thereon closes a switch 40 and short circuits the galvanometer so that its pointer is in an inoperative position. In an alternative embodiment parts 51-63 are removed and ring 43 is detachably coupled to the plate 9 so that the exposure time may be set automatically.

Filed: 1973-05-29
Abstract: 1426590 Hall effect devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 29 May 1973 [1 June 1972] 25356/73 Heading H1K A Hall effect device with a reduced offset voltage comprises a plurality of parallel connected Hall sub-elements disposed at the surface of a common semi-conductor body, the arrangement being such that the current paths in the sub-elements are in different directions. Fig. 1 shows a typical arrangement consisting of a pair of junction isolated sub-elements 7, 8 with mutually perpendicular current paths formed together with a junction transistor in an N-type layer epitaxially deposited on a P-type silicon substrate. The P-type isolation walls and transistor base, and N + contact zones and transistor emitter, are formed by successive boron and phosphorus diffusions and the contacts and interconnecting metallization by deposition and form etching of aluminium on a suitably apertured passivating oxide layer. The Fig. 6 arrangement comprises three subelements 37-39 with equally spaced radial current paths joined at their inner ends by common hub region 43 and at their outer ends by conductive track 33. The intervening radial isolation walls are not essential. Alternatives suggested are use of an insulating substrate, partial or complete replacement of the P-type isolation walls by grooves or inset layers of oxide, interconnection of the subelements by wires internally or externally of a housing and the provision of diffused P-type regions at the upper and/or lower surfaces of the epitaxial layer to reduce the effective thickness and hence conductance of the Hall element. The device which may be formed in multiple for later subdivision and as part of an integrated circuit may alternatively be of indium arsenide or antimonide. Other parallel arrangements are suggested with particular complete offset voltage compensation, the latter being produced by using sub-elements equal in number to half the internal angles of a polygon with their current packs aligned with the main diagonals of the polygon.

Abstract: <PICT:0682035/III/1> In making waxed string by drawing a length of a wick material through melted wax, such as paraffin wax, and a number of perforated draw plates, the string after having passed through a draw plate is subjected to the action of refrigerated air in a cooling chamber.  In a suitable plant, the wick material 1 from a roll 2 is passed through a funnel-shaped guide 4, a heated pan 5 of melted wax and a first draw plate 6 to a cooling chamber 9 through which it passes over one of a number of pulleys 8 in the form of a loop 1a-1b.  The wick material is then passed over one of a number of pulleys 20 several times so as to make a number of lateral cooling loops running between the pulleys 8-20, the loops being drawn through a number of draw plates 21 mounted laterally of the pan 5.  The forward end of the wick material is attached to a rotary drum 22 driven in the direction of the arrow d to advance the wick material longitudinally while coiling it on to its circumference.  Before the wick material is drawn through one or more of the draw plates 21, it may be immersed into melted wax or it may pass through free spaces or tubes in the pan 5 clear of the wax.  A final polishing draw plate 23 may be provided.  The cooling chamber 9 is provided with air-cooling elements 12, 13 forming part of any type of refrigerating machinery, such as machinery comprising a condenser 14, compressor 15 and electric motor 16.  The air cooler in the present instance comprises the two sections 12 and 13 disposed as shown in relation to the loops of wick material.  One or more fans 17 co-operating with guide plates 19 circulate the air in the direction of the arrow c transversely across the cooling elements 12, 13 and the loops of wick material. The wick material may comprise twined textile fibres or a narrow paper strip, which latter is pressed to a preliminary cylindrical form in passing through the draw plate while the surplus wax is removed.
