Title: Age-dependent pixel modification in composite images
Inventor: VOGEL HOLGER
IPC: G06T11/60
Filed: 2009-04-02
Abstract: A composite image (eg 100' or 1') is constructed from a plurality of component images 101' to 105'. The component images are captured using acquisition equipment, such as a camera 2, which may be movably mounted upon a support 3. The camera acquires component images as it is directed towards different parts of a scene. Component images are supplied to a computer 4 which processes them to form the composite image. An image processing/display system, such as computer 4, processes each of the component images such that a distinction can be made between composite image regions of different age, when displayed upon display equipment, eg screens 5a,5b. For example, older regions may be subject to age-dependent pixel value adjustment to yield darkening (eg image 101',102' etc), brightening or colour effects. Alternative methods of processing include image framing (eg 11', 12'), or resolution alteration. Accordingly, the user is instantly able to identify the relative age of processed regions of the displayed composite image.

Title: Sealing method for a turbocharger shaft seal and corresponding turbocharger
Inventor: PURDEY MATTHEW J
IPC: F01D11/00
Filed: 2008-06-03
Abstract: A turbocharger has a sealing arrangement between the turbocharger shaft and the bearing housing adjacent to the turbine and/or the compressor housings to restrict leaking of gas into the bearing housing. At least a pair of spaced sealing rings project from an annular surface of the bearing housing into corresponding annular recesses formed on the shaft. The trailing face of the second ring or the opposite surface of the recess has a plurality of radial grooves that define leak passages that serve to maintain a very small flow of gas from the turbine or compressor housing into the bearing housing. Alternatively there is a slot in the second ring to provide the leak passage. This ensures that there is a minimum gas flow so that a large pressure gradient is not applied across the second seal thereby avoiding wear, overheating and collapse of the ring.

Filed: 1921-04-07
Abstract: 175,587. Amsler, A. Feb. 14, 1921, [Convention date]. Testing physical qualities of materials.- Relates to self-adjusting gripping-devices for testing-machines, and consists in providing a lining of material softer than the test-piece, which is to be pressed into close contact therewith to prevent slipping. For soft or smooth test-pieces an auxiliary stretching-device is used which impresses the lining upon the test-piece before load is applied thereto. The test-piece D is held between wedges A having soft linings C which are impressed upon the test-piece as the wedges move outwards against the inclined sides of holders B as the result of the pull applied to the test-piece. If two hook strips E are used to couple the wedges as shown, the effect of the pull is to impress the lining upon the test-piece as the holders B move away from one another. When sufficiently impressed, the linings are kept in place by wedges F, the hook strips removed, and the test proper started.

Abstract: 399,565. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. April 12, 1932, No. 10466. Convention date, April 14, 1931. [Class 40 (iv).] The refund of a coin after an unsuccessful call takes place automatically when the subscriber hangs up owing to the transmission of a current reversal from the exchange, whilst the coin is collected if the call has been successful when the receiver is removed for the next call. When a coin is inserted and the substation receiver removed, any previous coin is directed into the collecting shoot 23 by an arm 22 on the switch hook K, and a short circuit 1, 2 around the transmitter and receiver is opened by the new coin. At the exchange, Fig. 1, relays LR, R1, R2, operate, and when the line is found relay BR operates disconnecting relay LR but maintaining contacts 3, 4 closed. When the subscriber hangs up, the coin drops to position 27. If the call has been successful, relay R3 is operated, but, if unsuccessful, an impulse of reversed current of greater voltage than the normal battery is transmitted over the line La, Lb in the interval between the relapse of relays RI, R2. Relay R4, Fig. 2, connected in series with a rectifier L1, responds to the reversal and by raising armature 24 refunds the coin through shoot 25. On an incoming call, relay R5 connected in the bell circuit across bridged rectifiers . L2 responds to ringing current to open the short-circuit around the instruments, its armature being locked by member 17 until the end of the call when it is freed by the operation of relay R4 in response to the "refunding" pulse. Relay R5 also blocks the refund shoot 25 to prevent refund of a coin not yet collected. In a system in which ringing takes place over one leg, ringing current over the other leg may be used for the refunding signal.
