Title: Electronic circuit
IPC: G03B9/58
Filed: 1971-04-19
Abstract: 1335613 Exposure control arrangements EASTMAN KODAK CO 19 April 1971 [17 March 1970] 24381/71 Heading G2A A photographic shutter mechanism comprising at least once shutter closing member which covers an exposure aperture to terminate an exposure, after an interval which is a function of the brightness of the subject, by means of an electromagnet controlled by a timing circuit has an electronic circuit including a measuring circuit 1 for indicating before exposure whether a correct exposure can be made, the measuring circuit being connected to the timing circuit to bias the timing circuit in accordance with the prevailing scene brightness to shorten the interval and being energized during initial travel of a shutter trigger mechanism, wherein switch means actuated on uncovering of the exposure aperture are provided which permit actuation of the electromagnet to permit the closing member to cover the exposure aperture. The circuit has two signalling lamps 2, 3 to indicate over- and under-exposure conditions, and a threshold value switch or trigger in unit 4 which together with a timing capacitor 10 and a photo-resistor 7 is switched to energize an electromagnet 5 at the end of the exposure period. The photo-resistor 7 is also used during the measurement phase, switches 8, 14 changing the photoresistor from the measurement to the timing circuit, the capacitor 10 being initially charged via a voltage divider 11, 12, 13 to a value dependant upon the scene illumination so as to electrically compensate for the inherent delay between energizing the electromagnet 5 and the exposure aperture actually being covered. To avoid the closing action to be initiated during the measurement phase, a switch 28, ganged to switch 8, is only closed upon the shutter opening to permit current to flow from a capacitor 6 through the electromagnet 5 upon switching of unit 4. In alternative embodiments, the triggering of the output stage may be blocked electronically; the threshold value switch may be arranged as a comparator; and the control lead of a threshold value switch in unit 4 is connected to the timing capacitor 10 by means of a change-over contact provided at switch 14.

Title: Improvements relating to Spot Type Disc Brake for Vehicles
IPC: F16D65/14
Filed: 1966-06-01
Abstract: 1,154,233. Spot-type disc brakes. DAIMLERBENZ A.G. 1 June, 1966 [4 June, 1965], No. 24452/66. Heading F2E. In a spot-type disc brake comprising a brake pad assembly 18, 23, which is applied against a brake disc (not shown) between lateral, clearance-providing guides 24, 25 by a piston 11 working in a cylinder 10, the piston axis 26 lying perpendicular to the plane of the brake disc, the piston is positively connected to the brake pad assembly by a connecting pin 15 having a ball-point connection at either end with the piston and pad assembly respectively to provide both universal angular movement and universal lateral movement of the pad with respect to the piston axis 26. The braking force applied by the piston is transmitted to the pad assembly at a piont P which is offset tangentially and radially from the brake pad axis 19 with respect to the brake disc to reduce wear. This is achieved in the embodiment shown by tilting the pin, but the same effect can be achieved by offsetting the pin laterally with respect to the axes 19 and 26. The arrangement is said to prevent brake pad squeal. The ball ends of the pin are retained in the part-spherical sockets of the pad assembly and piston by triangular clips 20, Fig. 2 (not shown).

Title: Improvements in or relating to split ball bearings
IPC: F16C33/60
Filed: 1929-08-12
Abstract: 334,044. Ablett, C. A., Kay, S., and Cooper Roller Bearings Co., Ltd. Aug. 12, 1929. Securing ball-races on shafts.- The inner race of a split ball or roller bearing is made in two, three, or more sections formed with tapering locating-surfaces each engaged by a registering ring assembled by r a d i a l movement, the tapering surfaces being of such steepness (e.g. 45‹ or over) as to ensure registration parallel as well as transversely to the axis. As shown, the inner race is in halves and the locating surfaces thereon comprise V-shaped grooves 22, which may have concave or convex sides, engaged by registering rings 24 in two parts united by recessed screws 28 and extending beyond the race ends. The inner race may be bored cylindrical to fit the shaft directly, or, as shown, a taper adapter 32 is used, the race being forced upon the taper by split nuts 38, the halves of which are bolted together and threaded to extensions 34 of the adapter, which extensions pass through recesses in the inner diameter of the registering rings. In one form, a single nut 38 at the smaller end only is used, and in a simpler form both nuts are dispensed with, the race being hammered into position. When an adapter is used the arrangement is such that when the race diameter is correct, the meeting surfaces of the race are not quite in contact and those of the registering rings are in contact. When the race is fitted directly to the shaft, the reverse is the case. Spigot-and-socket means may be provided to ensure that the rings are assembled so as to break joint with the race. The meeting surfaces of the race may be inclined to the axis and may be slightly bevelled. According to the Provisional Specification, the halves of the inner race may be located by a shroudlike sleeve between it and the shaft and the tangential screws 28 may be arranged as is described in Specification 312,830.

As shown, a microfiche card 5 is supported on a table 54 having an aperture 56 through which light passes. Light from the source 58 is reflected by a mirror 60 through card 50 and a magnifying lens system 62, to be reflected from a further mirror 64 on to a display screen 10. The card is gripped by a jaw assembly 66 connected to a follower block member 68 below the table 54. Follower block 68 can slide in two mutually perpendicular directions along rods 70 and 72. These are connected to further block members 74, 76 respectively, which themselves slide on rods 78, 80. Rod 70 is supported at its other end by a roller 82 running in a channel member 84. The movement of block 68 is controlled by the movement of blocks 74, 76 in the X and Y directions, and it has a pin 85 extending downwards into a guiding aperture (87, 89, 91) Fig. 4, (not shown). Blocks 74, 76 are moved by belts 86, 88 bolted thereto, the belts passing round drive rollers 90, 92, and idler rollers 94, 96. Rollers 90, 92 are driven by motors 102, 104, so that suitable control of the motors can produce any required X, Y movement of the fiche, to bring a particular frame into position for viewing. The position of this frame in relation to the fiche as a whole can be indicated on a chart 18 having a grid pattern corresponding to the fiche. A beam of light from a source 106 is reflected from a condensing mirror 108 to fall on the chart 18. The mounting of source 106 and block 108 is linked to block 76 and block 68 so that mirror 108 follows the X, Y movement of the fiche, and so indicates the location of the fiche frame (e.g. as at 110) which is'being viewed. This frame may be selected automatically from a keyboard 16, or manually by means of a joy-stick control 20. The fiche may be firmly located against a transparent platen by air-pressure Fig. 13, (not shown).

W., 3, Olive Tree Road, Wavertree Suburb, and SMITH, S. R., Rock House, Old Swan, all in Liverpool. Sept. 5, 1931, No. 25000. Addition to 374,851. [Class 38 (v).] In the relay described in the parent Specification in order to effect a further reduction in the size and mounting space required, the two sets of contact springs, which extend at the sides throughout the length of the relay, are so shaped that the contact points are situated at the front of the relay within a space enclosed by an extension of the cylinder surrounding the energizing coil. As shown in Fig. 7 the free ends 40 of the two contact spring sets are inclined towards the axis of the relay so that their double contact points lie within an extension of the space bounded by the cylindrical energizing winding 30. The contact sets are secured to the relay by insulated bolts 41, 43 and the relatively fixed contact springs are secured in spaced relationship at intermediate points of their free portions by insulated bolts 42 the springs being shaped as shown so that these bolts clear the relatively movable springs. The relay core, Fig. 5, is provided with L-shaped polepieces 31, 32 to which a flat armature 33 is adapted to be attracted, the armature pivoting about its rear end on the polepiece 31 and being retained thereon by projections of a springy plate 34. The free end of the armature is cut away to clear the contact spring clamping bolts 42, the corners of the armature engaging insulating pins 44 carried by the movable contact springs. Non-magnetic pins 45 prevent the armature sticking to the polepieces, the return movement of the armature after attraction being limited by a bent-over stop 39. Relays of the type described are secured in position on a mounting plate of the type shown in Fig. 11 by means .of cup-shaped washers 46 and nuts 47, the washers bearing around the securing holes in the plate which are large enough to accommodate the core fastening nut. Pins 48 carried by the polepiece 31 enter small holes in the mounting plate so that the relays cannot be twisted round while in position. Holes are formed in the mounting plate so that the connecting ends of adjacent sets of contact springs of adjacent relays may pass through the same holes in the mounting plate, permitting the relays to be spaced as closely as possible. Connecting tags for the ends of the relay windings are accommodated as shown in extensions of these holes and the polepiece 31 is cut away as shown in Fig. 8 to clear these winding tags.
