Title: Laser designator and guidance system
Inventor: MORCOM CHRISTOPHER JOHN
IPC: F41G7/22
Filed: 2009-07-13
Abstract: A laser designator is disclosed comprising a signal generator 2 and a laser 3 for generating a modulated optical signal beam 21. The beam is directed to a remote object 22 which reflects the signal. A portion 23 of the light reflected by the remote object is focused onto a light sensitive detector 6. A cross correlator 8 calculates the cross correlation between the received, delayed signal, and the original modulation signal. The cross correlation has a peak corresponding to the time of fight of the optical signal, and hence the distance to the remote object 22. Whilst the laser designator is operating, a portion of the light reflected by the remote object 22 is also captured by a receiving lens 11 of a guidance system 12. This focuses the received light onto a multiple region light sensitive detector 13. The outputs of each quadrant of the detector 13 are passed to separate cross correlation units 15, and peak detectors 16. The amplitude of the peak is determined for each quadrant, and can be used by a guidance and control system 18, typically to guide a vehicle towards the remote object 22.

Title: Stacking and turning products
Inventor: WEBB MICHAEL JAMES MORLEY
IPC: B65B35/12
Filed: 2009-07-24
Abstract: An apparatus features a collating conveyor 4,6, transfer means such as a pusher (9 fig.2), and turning means, such as a rotatable trough 10. The collating conveyor 4,6 is inclined to the horizontal and has lugs 5,7 or similar to support a product 2 or stack of products 8 by gravity. Products 2 leave a input conveyor and fall onto the collating conveyor, which indexes its lugs 5,7 downwards so as to form a stack 8. This also partially turns the products upon their edges, after which pusher pushes the stack 8 onto a rotatable trough 10, which completes the turning of the products onto their edges. A gripper (11,fig.3) may then lift the turned stack (8,fig.3) and place it in a packaging box. The collating conveyor may be formed of two side by side belts (4,6 fig.2) with laterally overlapping lugs 5,7 to double the throughput of the collating conveyor.

Title: A fastener system for an LCD TV Display
Inventor: MARTIN PAUL
IPC: H04N5/64
Filed: 2009-10-19
Abstract: The invention relates to a fastener system (22, fig 1) for fastening an internal PCB (20, fig 1) of an LCD TV to an internal printed circuit board support and electrical grounding panel (18 fig 1) of an LCD TV 10, and grounding the PCB to the panel. The fastener system (22, fig 1) comprises four pins (24, 26, 28, 30, fig 2,3) and four resiliently deformable clips/springs (32, 34, 36, 38 fig 2, 3). Each pin is electrically conductive and for attaching to an internal printed circuit board support panel of an LCD TV. The resiliently deformable clips/springs (32, 34, 36, 38 fig 2, 3) are electrically conductive and for attaching to an internal PCB of an LCD TV. Each clip/spring 34 defines a keyhole like socket (54, fig 6) for a pin 26. The socket has a larger opening (80, fig 6) in communication with smaller opening (84, 86, and 88 fig 6). Each pin 26 has an enlarged head 44, designed for passing through a hole in PCB, and for axial entry to larger opening (80 fig 6) of corresponding socket (54, fig 3). Transverse movement of the clip/spring 36 relative to the pin 26 to move pin towards the smaller opening (84, 86, 88 fig 6) is able to cause an axial and/or a radial force on each clip/spring, for pressing each clip/spring 36 against the pin and the PCB, for fixing the position of the PCB with respect to the printed circuit board support panel, and for electrically grounding the PCB to the PCB support panel, via contact between each clip/spring and each metal pin.

Title: Improvements in micrometer gauges provided with an indicating device
IPC: G01B3/18
Filed: 1922-04-11
Abstract: 179,910. Krupp Akt.-Ges., F. May 12, 1921, [Convention date]. Linear - dimension gauges. - In micrometer calliper gauges having an indicating-pointer and dial attachments to the movable contact member such contact member is associated with the screwed spindle, and the casing of the lever mechanism for the contact member is arranged symmetrically relative to the axis of the spindle and compa.ctly between the movable gauging face and the end of the screw thread on the spindle remote from the gauging face. The invention is described as applied to both internal and external gauges. In the first form, the casing E of the lever mechanism is rigidly mounted in a sleeve B<1>, Fig. 1, slidable against the resistance of a spring D within a hollow threaded spindle B. The thimble C attached to the spindle carries an abutment b' for a rod H, which at its other end bears against the movable bolt or pin G of the lever mechanism. The casing E is screwed tightly against a shoulder b<6> on the sleeve B', and rotation of the casing and sleeve are prevented by a stud a<3> engaging a groove b<5>. The sleeve B<1> is fitted with a ring b<3> which is forced against a shoulder b<4> by the spring D. The gauging-face e<2> is formed on the dial casing. For adjusting the gauge to zero, the thimble is turned to move in the abutment b<7> and the spindle part B against the resistance of the spring D, the sleeve B<1> being immovable by reason of the contact of the two gauging faces. The abutment b<7> moves the rod H to deflect the pointer F to the zero mark on the scale. If the thimble is turned in the reverse direction the sleeve B<1> and casing E are moved by the engagement of the shoulder b<4> with the ring b<3>. In the second form of gauge, shown in Fig. 2, the casing E of the lever mechanism is placed outside the bow A. The movable contact face h<1> is formed on the end of the rod H, which has a collar h<2> bearing against a shoulder b<9> on the sleeve part B<1>, while a ring J on the sleeve bears against an annular flange b<8> on the spindle part B'. This gauge has a wide range of adjustment. An internal gauge comprises a threaded spindle M, Fig. 3, with a thimble C attached to it, and a sleeve K adjustable over the spindle. The casing E is slidable within the spindle against the resistance of a spring N, and carries one contact face e<2>. A lug e<4> and notch m<2> prevent rotation of the casing, and a collar e<5> on the casing abuts against flange m<3>. The pin G of the lever mechanism bears against a cap m<4> attached to the spindle part M, and the sleeve K carries a cap k<2> upon which interchangeable contact members k<3> may be mounted. In setting this gauge the thimble is held while the sleeve K is turned. Adjustment is made for a greater distance than the standard diameter of the boring.

Abstract: 1,262,432. Collet actuating devices. HARDINGE BROS. Inc. 4 March, 1970 [13 Oct., 1969], No. 10451/70. Heading B3T. A collet actuating device comprises an annular casing 44 concentric with the machine spindle 20 having a collet X at one end, a collet draw tube 22 connected to an actuating member 26 within the casing and Belleville spring washers 24, 25 located concentric with the spindle between a shoulder on the actuating member 26 and a sleeve member 28 attached to the casing, which provide an axial force for displacing the draw tube axially relative to the spindle 20 to effect closing of the collet. The opening of the collet is effected by a fluid actuated piston 42 operable within an annular chamber 58, in the casing the piston acting through a bearing 36 to compress the Belleville springs and effect axial displacement of the draw tube in the opposite direction and hence opening of the collet. The spindle, draw tube, actuating member and sleeve member all rotate in unison with the spindle, the casing and piston being mounted on bearings 36, 70 are non-rotatable and are retained in position by slot and key means 46, 50 the key being secured to a part of the  machine frame. The displacement of the piston is controlled so that its length of stroke is less than the total permissible deflection of the Belleville springs. The axial position of the drawtube and collet is adjustable relative to the spindle to permit operation with workpiece diameters of varying size.
