Patent GB-2237511-A (GB)
Title: Non-reusable syringe
Inventor: ALVAREZ PEREZ CARLOS
IPC: A61M5/50
Filed: 1990-10-15
Abstract: A disposable syringe comprises a plunger (10) which includes a flange (15) and also a partition member (4) which includes a frangible portion (11). When the plunger is operated during an injection the frangible portion (11) is perforated and the perforation thus formed is covered and sealed by the flange and the injection may therefore proceed. However, the flange must be removed from the perforated partition if an attempt is made to re-use the syringe by withdrawing plunger (10) and, since the perforation is then unsealed, nothing may be sucked into the syringe in normal use. The syringe is therefore unserviceable after only one use. <IMAGE>

Title: Wrapping bales
Inventor: PENTITH G R O
IPC: A01F15/07
Filed: 1991-03-02
Abstract: A structure is attached to a big round baler, usually at the baler's axle, which contains within the floor framework a small central conveyor which transports the bale from the baler a few feet to a position where its linear progress is stopped by a cantilevered roller suspended forward from a swinging gate. Continued movement of the conveyor causes the bale to rotate about its own axis. From the floor framework there are four vertical legs which support an overhead framework from which is suspended a swinging arm, on which is mounted a roll of cling film plastic and a stretch unit. The swinging arm rotates round the rotating bale applying successive overlapping layers of plastic film which completely seal the contents of the bale. This structure is semi-mounted to the baler so that it is to all intents and purposes part of it. The power to the wrapper is derived from the tractor similar to the baler and all the actions of the wrapper are sequence controlled automatically. <IMAGE>

Patent GB-2252479-A (GB)
Title: Data transmission by modulation of a power signal
Inventor: SHARPE BRIAN ALLAN JOHN
IPC: B60C23/04
Filed: 1992-01-09
Abstract: Data are transmitted in binary code to a data reception station on a first structure, for example an aircraft, from a data processing station (20) on a second structure, for example a landing gear wheel, which is movable with respect to the first structure. A power signal is transmitted from the first structure to the second structure by means of a rotary transformer (36) and it is picked up by the processing station (20). The processing station comprises an electronic module (29) which supplies processed data in binary-coded form and generates signals with modulation by frequency changing (FSK) representing binary-coded data. The FSK signals are modulated onto the power signal for transmission to the data reception station where they are demodulated and converted into a data form which is suitable for display. That minimises the errors which but for this could result in the alteration in the signals during transmission, and avoids a need for data conversion from the analog form to the digital form after transmission, which would be an additional source of inaccuracy. <IMAGE>

Title: Fast deflation valve for a hot air aircraft.
Inventor: LINDSTRAND PER AXEL
IPC: B64B1/62
Filed: 1993-09-18
Abstract: The fast deflation valve, used for high wind speed landings, is provided by pulling a parachute (4, Fig. 2) downwards from the centre. To achieve this movement, a lock 56 is first released which permits the retaining lines (6, Fig. 2) to be pulled towards the centre of the parachute. The lock is centrally located outside of the parachute and connected to the top of the parachute, so that pulling the operating line (50, Fig. 2) causes the lock to release. Locking lines 51 connect the lock to the outer ends of the retaining lines. An arming system is provided which, when installed prevents the lock from releasing and consists of a separate arming line (63, Fig. 4) and an arming pin (64, Fig. 4). The downwards movement of the parachute, once the lock has released, is restricted by stopping cord (62, Fig. 4) and stopping rings 54. Release of the locking lines allows the retaining lines to lengthen and hence open a large hole for hot air escape. <IMAGE>
