Patent GB-2071251-A (GB)
Title: Safety device for a rotary machine
IPC: D06F49/00
Filed: 1980-03-05
Abstract: A safety device for a spin dryer or washing machine ensures that the lid, which is pivoted at 50, cannot be opened until the motor has been switched off and the machine has come to rest. This is achieved by a member 30 which, immediately on commencement of deceleration of the driving motor caused by automatic application of a brake, rotates into its locking position against the action of a spring 18 to prevent the lid from opening. The deceleration causes the motor body 11 to react and move in the direction of arrow A and turn the shaft 26 through a cam 20 attached to the motor body. The member 30 prevents the lid 32 being opened, even though the lid has been unlocked by moving locking means 36 in the direction of the arrow. When locking means 36 is moved to the left it disengages lever 38 from microswitch 40 which interrupts current to the motor and automatically brings into effect an electro-mechanical brake (not shown). The braking effect is used to create a torque on shaft 26 which turns member 30 to the position shown above a locking tab 52 on the lid where it inhibits opening of lid 32. When the motor stops, the shaft 36 returns to its original position and member 30 moves angularly away from locking tab 52 to allow the lid to be opened. <IMAGE>

Title: Device for protecting blooms
IPC: A01G13/02
Filed: 1980-03-20
Abstract: A device for protecting a bloom comprising a support member 10 which can be fixed to the top of a cane and which has a slot 16 into which the stock of the bloom to be protected can be accommodated. A first frame member 18 in the form of a loop is fixed to the support member and is shaped so that it surrounds the bloom but does not contact it. One or more further loop frame members 24, 26 shaped similar to the said frame member are pivotally mounted on the support member so that they can be moved from a position in which they lie clear of the bloom to a position in which they support it. The frame members are provided with detent means so that they can remain fixed in the assembled position and in this position they may support a bag fitted over the bloom protector. <IMAGE>
Patent GB-2051540-A (GB)
Title: Guidance control means for a harvester
IPC: A01D41/127
Filed: 1980-05-29
Abstract: Guidance control means for guiding a harvester along plant rows, especially maize, comprising two oppositely disposed spring-loaded feeler elements (4) arranged at two swath board points of the harvester. The feeler elements (4) are so connected with inductive transmitters (5) that the transmitters in the rest position of the feeler elements are adjusted to provide output voltages which are equal but of opposite polarity. On the detection of a row (6) of plants, the deflection of the feeler elements (4) takes place either equally or unequally. Unequal deflection of the feeler elements as a consequence of, for example, varying row spacing or lateral displacement, provides a resultant output voltage of the feeler element pair equal to the difference of the output voltages of the two transmitters and to a first approximation proportional to the displacement of the scanned row of plants. This voltage difference can be amplified and applied to act on a hydraulic steering system of the harvester to provide a steering correction. <IMAGE>

Patent GB-2054773-A (GB)
Title: Transmission Ratio Selecting Mechanisms
IPC: F16H61/70
Filed: 1980-07-21
Abstract: A transmission ratio selecting mechanism for displacing a coupling sleeve of a synchromesh unit includes a cam member arranged to be moved by a ratio selector means (typically a hand lever) and having a cam surface which is contacted by a follower arranged to axially displace the coupling sleeve on movement of the ratio selector means to effect a synchronised ratio selection. The cam surface has three zones, a first zone (P) contacted by the follower during movement of the coupling sleeve towards the synchronising position of the unit, a second zone (Q) contacted by the follower during synchronisation, and a third zone (N) contacted by the follower after synchronisation has taken place and as the coupling sleeve is moved towards its fully engaged position in which the ratio selection is complete. The first, second and third zones are shaped so that a tangent (103) to the cam surface at the point of contact (M) with the follower during synchronisation makes a smaller angle ( alpha ) with the direction of movement (F) of the cam member than tangents (such as 102) drawn to points of contact (L) with the first and third zones of the cam surface so that for a given selection force applied to the cam member a larger ratio engagement force (FF) is applied to the follower during synchronisation than when the follower is in contact with the first and third zones. <IMAGE>

Title: Exhaust Gas Recirculation Control for an I.C. Engine
IPC: F02M26/62
Filed: 1980-12-18
Abstract: A valve 7 controlling an exhaust gas recirculation duct 12 is closed in response to an increased fuel pressure in its actuator 9 resulting from greater than a predetermined rate of accelerator pedal depression. A damper 53 on the pedal linkage 48 causes a spring 51 to be compressed to reduce the rate of movement of the injection pump delivery regulating lever 47. In response to a predetermined pressure in the damper 53 or compression of the spring 51 a switch is closed to energise a valve 63 for a fixed period or the period for which the pressure exceeds the predetermined value. The switch may be closed at full pedal depression. The valve 63 may connect the actuator 9 direct to the fuel feed pump 17 or cause the outlet 33 of the pressure comparator 24 to be opened due to pressure reduction in the comparator chamber 30. <IMAGE>
Patent GB-2078297-A (GB)
Title: Internal combustion engines
IPC: F02M25/00
Filed: 1981-03-12
Abstract: It is known from United Kingdom Patent Specification No. 1,513,051 to provide an internal combustion engine with a supply of a "mineral oil" paraffin, kerosene or white spirit in a vaporised condition, with the customary petrol/air mixture, to drive the engine. As the temperature(s) to which the "mineral oil" is heated to vaporise it was lead to residue build-up and eventual blockage of the tubing, the present invention provides coaxial tubes 9 between the "mineral oil" tank 8 and a trap 10, said tubes 9 extending into the exhaust manifold to effect vaporisation of the oil, the outertube being of stainless steel and the inner tube being of copper. This avoids "cracking" of the "mineral oil" and therefore prevents blockage of the tubing. <IMAGE>
Patent GB-2095606-A (GB)
Title: Forming a reinforced plastic sheet using a flexible membrane as carrier
IPC: B29C41/08
Filed: 1981-03-28
Abstract: A reinforced plastics article is manufactured by applying a curable reinforced plastics mixture 12 on to a flexible membrane 11, then deforming the membrane 11 to urge the mixture 12 against a shaped support 13, and allowing or causing the mixture to cure. By applying the mixture, (e.g. by spraying) to the membrane, instead of directly to the support, the mixture can be applied while the membrane has a simple, easily sprayable shape, it being the subsequent deformation of the membrane towards the support which causes the mixture to be compacted and to conform to the final desired shape. <IMAGE>

Title: Nutritive compositions containing fatty substances and a process for the preparation thereof
Inventor: TRAITLER HELMUT
IPC: A23L35/00
Filed: 1983-04-11
Abstract: The oil of pips of fruits of the Ribes genus is an abundant, cheap source of  gamma -linolenic acid. It is extracted using solvents from dried and ground residues from the production of juices, preserves and jellies or brandies, liqueurs and schnapps of fruits, such as blackcurrant, redcurrant or gooseberry. According to a preferred embodiment, the residues are treated with ethanol before being extracted with hexane in order to free the oil from most of the free fatty acids, waxes, colorings and odorous compounds. The refined oil is a valuable ingredient in cosmetic, dermatological, dietetic and pharmaceutical compositions.
