Title: Drogue chute speed mode selector
Inventor: ARONNE ARMAND J
IPC: B64D25/10
Filed: 1991-05-02
Abstract: An ejected pilot's seat is provided with a drogue chute 18 anchored to the seat by means of a bridle (20, 24, 28, 34). The bridle includes a strap (34) having redundant load cells 38, 40 parallel connected in redundant fashion. The load cells measure tension in the strap. Data from the load cell is conducted through the bridle to a microprocessor 52 contained within the seat. The microprocessor includes look-up tables for correlating tensile load in the strap to forward velocity of the ejected pilot. Upon acquisition of a preselected optimum velocity, the drogue chute is released and a main chute is deployed to increase the likelihood of a safe descent to the ground. <IMAGE>

Title: Automatic actuation of friction clutch
Inventor: TELLERT RUDY
IPC: F16D48/06
Filed: 1991-06-20
Abstract: A device for the automatic actuation of a friction clutch (1) in the transmission line of a motor vehicle between an internal combustion engine (3) and a change-speed gear (5) controls the clutch (1) through a setting drive system (11) controlled by a control system (19, 25, 31) in starting driving in dependence upon the engine rotation rate (n) and in the changing of higher gears with predetermined setting speed. An indicator (45) detects the position of a gear-change lever (7) of the charge-speed gear (5) and on actuation of the lever generates a signal initiating clutch disengagement. The control system (19, 25, 31) on starting of the engine (3) controls the drive system (11) to disengage completely the clutch and set a store (69) which then generates a blocking signal preventing engagement of the clutch. The indicator (45) clears the store (69) on actuation of the lever (7) or when the lever is in neutral, third or a higher gear. <IMAGE>

IPC: G09F7/18
Filed: 1992-10-28
Abstract: In the field of signposts and signboards, there is a need for a readily adjustable and dismantleable sign post system which is aesthetically pleasing. The disclosure relates to a clamp (15) for a signpost (10), the clamp comprising a first clamp member (16), a second clamp member (17) rigidly secured thereto; a third clamp member (18) moveable in the space between the first and second clamp members and a fourth clamp member (19) moveable externally of the first and second members. The third and fourth clamp members (18, 19) are rigidly secured together, and the four clamp members are retained captive relative to one another thereby to create two pairs of simultaneously operable clamp jaws. A bolt (26) passing centrally through the four clamp members may be screwed to a reaction surface formed by, e.g., a support post(12) and tightening of the bolt (26) causes tightening of the clamping jaws. The clamp members may include a number of mutually aligned recesses or apertures (33) for clampingly receiving a portion (38) of a signboard. The clamps may be secured to two support posts so that one or more signboards may be held between the posts (Figure 3). <IMAGE>

Title: Manual-to-power selection for a printer paper feed.
Inventor: NOJIMA MASAMITSU
IPC: B41J19/96
Filed: 1993-02-12
Abstract: A clutching mechanism enables a feed roll (which may be a rotary platen) to be driven either manually or by a motive power source. As described, the feed roll shaft (2) has both a handwheel (1) and a first clutch disc (3) fast therewith, and also has a second clutch disc (4) mounted thereon for both axial and rotary motion. A spring (6) urges the clutch discs together, whereby to engage ratchet teeth (3a, 4a). A sector of the periphery of the second clutch disc (4) bears teeth (4b) which are engaged by a sector-shaped gear (8) fast with an oscillatable shaft (11). A cam slot (7) in the untoothed part of the periphery of the second clutch disc (4) engages a fixed pin (10) on the machine frame. ACTION: In the "at rest" position the second clutch disc (4) is driven by the sectorial gear (8) to the position shown (Fig. 3) whereby it is cammed out of engagement with the first clutch disc (3) by the pin (7). The handwheel is usable in this condition. Oscillation of the sectorial gear (8) rotates the second clutch disc (4) so that the pin enters the broad part of the cam slot (7), thereby allowing the teeth (3a, 4a) to engage and drive the shaft (2). When the oscillation of the sectorial gear reverses, the teeth (3a, 4a) "ratchet" past each other until they are disengaged by the pin (7). <IMAGE>

Patent GB-2267568-A (GB)
Title: Acoustic flowmeter
Inventor: JONES LAWRENCE ANTHONY
IPC: G01F1/66
Filed: 1993-07-16
Abstract: An acoustic flowmeter comprising an acoustic signal source, which launches a signal output into a flow path and detects the signal after transmission through the flow path. The time taken for the signal to be transmitted through the flow path is measured and the rate of flow within the flow is calculated from the measured transmission time. In order to improve the signal to noise ratio of the meter, acoustic signals transmitted through the flow path generate a first signal which is mixed with a second signal of different frequency to generate a third signal. The first signal is also mixed with a fourth signal to generate a fifth signal, the second and fourth signals being of the same frequency and in quadrature. The third and fifth signals are applied to a pair of low pass filters (79) having a cut-off frequency selected such that signals at a frequency substantially equal to or less than the difference in frequency between the first and second signals are passed. The filtered third signal is mixed with the second to generate a sixth signal, and the filtered fifth signal is mixed with the fourth signal to generate a seventh signal. The sixth and seventh signals are combined to generate an eighth signal which is representative of the signal transmitted through the flow path. The signal to noise ratio of the eighth signal is very much larger than the signal to noise ratio of the first signal as a result of rejection of unwanted signal components in the low pass filters. <IMAGE>

Title: Animal feeds
Inventor: MIDDLEHURST ROBERT A
IPC: A23K1/00
Filed: 1993-07-29
Abstract: Wet cooked animal feeds are made from oilseeds, pulses and/or cereals, by first passing the raw feed through a cracking roll (7) before wet cooking (15). The cracking roll cracks the shells of any oilseeds hut without releasing all the oil, and this facilitates subsequent cooking and oil release. Pulses and cereals are reduced in size by the cracking roll which also facilitates cooking and further treatment. The process enables new feeds to be made comprising 100% full fat wet cooked oilseeds, and mixtures thereof with cereals and pulses, and also wet cooked cereal and pulse flaked products.
