Title: Making a connecting rod of cast metal for an internal combustion engine
Inventor: MAHNIG FRITZ
IPC: B22D15/00
Filed: 1984-11-30
Abstract: The rod's connecting arm extending between bearing eyes (2, 3) has opposed substantially parallel flanges (7), and is cast with a cooling portion (4, 5) on the flanges (7) which cools and solidifies in advance of the solidification of the bearing eyes (2, 3) and the flanges (7) in order to promote controlled cooling of the bearing eyes and the flanges. Subsequently, at least part of the cooling portion (4, 5) is removed, though a thicker portion (6) may remain as a bridge between the flanges (7). Additionally or alternatively cooling portion(s) may be cast on the outer surfaces of the flanges (7) and removed after solidification and cooling of the rod. For reasons of strength, the small bearing eye may be provided with an oval outer contour. <IMAGE>
Patent GB-2168146-A (GB)
Title: Optical wavelength measurement
Inventor: BYRON KEVIN CHRISTOPHER
IPC: G01J9/00
Filed: 1984-12-06
Abstract: The wavelength of an optical signal 12 is determined by attenuating at 1 the optical signal to a predetermined level and transmitting the attenuated optical signal along an optical fibre 7 to a detector 9. Since there is a monotonic change in loss in the optical fibre over a wavelength range covering the visible and near infrared, the detector current is related directly to the loss in the optical fibre and thus the wavelength of the transmitted optical signal. The determined wavelength is displayed on a meter 11. The optical fibre 7 may be omitted if the detector current itself varies with wavelength. <IMAGE>

Patent GB-2176917-A (GB)
Title: Data port
Inventor: SPROAT MARTIN
IPC: H04L29/06
Filed: 1985-06-19
Abstract: In a packet system a data port between a data terminal and a controlling processor uses a USART (Universal Synchronous/Asynchronous Receiver/transmitter), which in conventional practice is used as a byte-by-byte interface, with each byte to the transferred causing a separate interrupt. On a busy line or where several ports are controlled from one processor this causes many processor interrupts. To minimise this, the data incoming to the port is monitored in the port to detect preset byte combinations (e.g. message end), the presence of such a combination causing an interrupt. Bytes on reception go into a buffer, which is monitored to see how full it is. When it reaches a preset level of fullness an interrupt is also sent. In both these cases the interrupt causes data transfer to the processor. In addition the port has a buffer for the reception of data output from the processor; this is monitored and if empty the port issues an interrupt to "tell" the processor that it can receive data. These arrangements provide a significant reduction in the number of interrupts needed, which is important, especially where the processor serves a number of data ports. <IMAGE>

Title: Language recognition apparatus
IPC: G06F17/28
Filed: 1985-07-01
Abstract: Language recognition apparatus includes a cell (10) for comparing (14) input grammatical rule characters with a stored rule symbol (16) synchronously with comparison (20) of an input character with a second stored symbol (22). An AND gate (24) indicates simultaneous match, and effects output (38) of a third stored symbol (34) for comparison with the first stored symbol (16) synchronously with input of a second character for matching with the second symbol (22). A fourth stored symbol (42) is transferred (50) to a remote store for subsequent recall and comparison with the first stored symbol (16) in synchronism with third character input provided prior matches have occurred. The cell (10) tests successive input characters for compliance with a rule of grammar expressed by the stored symbols. Compliance is indicated by unrealisable recall of a symbol from the store in combination with lack of an input character. Several cells may be arranged to test for compliance with all rules of a grammar. <IMAGE>

Title: Solid state generator of perpetual electron precession
Inventor: KALFAIAN MEGUER V
IPC: G01R33/20
Filed: 1985-08-02
Abstract: A suitable substance (2) is powdered and implanted with high velocity electrons. This electron implanted powder (16) is then solidified into a cylindrical shaft under control of an RF field (13) at a frequency equal to the precessional resonance of the implanted electrons (5, 6) at their rest positions in the particles. The locked resonances between the precessions of the implanted electrons (5, 6) and the control RF field (13) causes the poles of the implanted electrons (5, 6) to tilt toward the RF field (13) radiation uniformly. But due to the high ratio between the field strength required to tilt the poles of the implanted electrons (5, 6) from their rest orientations in the particles, and the physical strength required to physically orient the powdered particles (16), instead of the electrons (5, 6) being tilted from their rest orientations, the powdered particles (16) are oriented in an order such that, the solidified shaft contains uniformly polarized implanted electrons (5, 6). When this shaft is inserted in a high field strength cylindrical permanent magnet (M4), the uniformly polarized electrons (5, 6) will precess with RF radiation at high energy level.
