Title: Machine for cutting stalks of mushrooms - which are floated on water to conveyor belts which present them to circular cutters
IPC: B26D3/26
Filed: 1974-07-29
Abstract: Machine for cutting the stalks off mushrooms comprises a portion in which the mushrooms are floated on water to bring them, one by one, into a predetermined position with regard to the means provided for carrying them to the cutters. The mushrooms travel in vibrating gutters, fed with water, and on belts provided for presenting them to the cutters. The belts have a gap which allows the passage of the greater number of the mushrooms but excludes those which exceed a predetermined dia. The cutting end of the machine has a first conveyor circulating around pulleys with horizontal shafts, these shafts, form a triangular frame which is partly counterbalanced by the spring. The stalk of the mushroom makes contact with the inclined belt; it is lifted and its head lifts the first conveyor and its supporting frame. At the moment the mushroom comes to the right of the pulley its stalk is engaged between two circular cutters and is severed at the extreme end, carrying the earth and the mycelium. Passing onwards another belt brings the mushroom to a suitable height for cutting by the circular blades so that the length of stalk remaining conforms to a fixed standard. The removal of the stalks in bulk by the machine effects a considerable saving in man-power. The portion of the stalk recovered can be utilised.

Title: Diagonal ply tyre - having circumferential shrunk reinforcement at shoulders to prevent slipping of diagonal cord ends
IPC: B60C9/22
Filed: 1974-12-09
Abstract: A pneumatic tyre has cross-ply reinforcement with additional reinforcement at both shoulders of the tread. This additional reinforcement is circumferential and consists of a material which shrinks at vulcanisation temp. and presses the extreme edge of the diagonal ply layer below it onto the diagonal layer below that. The width of the additional reinforcement is pref. about one-tenth of the total tread width. The effect of the gripping action on the diagonal ply is to prevent the ends from slipping and thus to ensure that the ends of the diagonal cords accept the same tension as the middle portions.

Title: Air cushion continuous drier for rolls of sheet material - esp. paper, has emergency carrier conveyors to clear torn material before blockage
IPC: F26B13/10
Filed: 1974-12-30
Abstract: Continuous air drier for band of material which is substantially impervious to air, the band following a path comprising one or more horizontal runs between jockey rollers and being pulled forward along the path with each horizontal run of material supported on a cushion of air from air jets. Beneath each horizontal run of material, runs a carrier conveyor, which is of smooth material, perforated to allow passage of air which supports the material clear of the conveyors. The conveyors normally run very slowly but speed up rapidly to equal the material speed if the material should tear and fraction fail. Pressure of air to jets is adjustable to hold material down on to the conveyors as necessary to prevent slip when the conveyors speed up and carry the material. The drier is esp. for bands of material such as paper, cardboard and plastic sheeting.

Title: Distance measurement device - uses frequency changes in IR detectors as analogue of distance between object and focus of optical system
IPC: G01S11/12
Filed: 1975-02-19
Abstract: This equipment determines the distance between an object (P) and a fixed point. Converging infra-red radiation beams (1 to 11) are directed past the object (P) onto a number of reflectors (13-22) which are arranged to focus onto the centre of a convex lens (23). The light is then fed via a grating (12) and a plano-convex lens (24) onto two infra-red detectors (25N and 25P). The housing (27), which contains the reflectors and other optical components, is swung around the object. The electrical outputs of the detectors will have a frequency component which is proportional to the distance between the object and the focal point of the beams. One of the detector outputs is inverted and added to the other. The combined output is fed via band-pass filters to frequency detectors and a distance display. The basic concept can also be used with other forms of electro-magnetic radiation.

Title: Easily collapsible solar energy trap of flexible materials - formed of inflatable sections and useful for heating swimming pools
Inventor: LEMERY JEAN-PAUL
IPC: F24S10/70
Filed: 1976-07-30
Abstract: Solar energy trap comprises a receiver and a transparent chamber which simulates a greenhouse effect. The receiver is composed of >=1 flexible tube of which at least the part of its surface orientated towards the sun is a dark colour. It is placed either in or in contact with the transparent chamber. The transparent chamber is formed from inflatable elements which either themselves form the chamber or alternatively support a transparent sheet which encloses the chamber. The inflatable support elements can be used to give a degree of orientation relative to the sun. It is partic. useful in situations demanding only intermittent use, e.g. heating a swimming pool. The appts. is light and easy to assemble and dismantle. It is therefore possible during periods of disuse to deflate the inflatable sections and having rolled up the component parts, to store the whole appts. in a relatively small space.
