Abstract: A crop engaging device for conveying and/or treating crop comprises a support and a plurality of crop engaging elements extending outwardly from the base. The device may be a rotor (11,12) which may be driven to convey or retard crop, or may be freely rotating. The crop engaging elements are in the form of transversely extending ribs (22). The crop engaging elements may have specified yielding characteristics, being yieldable in a preferred direction and being yieldable predominantly at a region spaced from the outer tip. Two cooperating rotors (11,12) may have crop engaging elements which intermesh so that ribs on one rotor (12) interleave with ribs on the other rotor (11) to condition the crop. The ribs on the lower rotor (11) are shaped with deep serrations so as to form outwardly directed spikes. <IMAGE>

Title: Copy protecting computer programs
Inventor: PHILLIPS DAVID ALLAN
IPC: G06F21/80
Filed: 1986-03-11
Abstract: A computer program recorded on e.g. a magnetic recording medium (disc or cassette tape) is associated with a test program. The record member has a discontinuity, e.g. a patch free of magnetic material. The test program includes instructions to record back on to a section of the record member including the discontinuity, data already loaded onto the computer from the record member. The so recorded data is then replayed and compared with the original data to detect the effect of the discontinuity. If the expected effect is not detected, the computer is disabled from running the program, as by its memory being cleared by the test program. A PROM-and-RAM cartridge may be used instead of a magnetic recording medium. <IMAGE>

Title: A butterfly valve
Inventor: GEISER FRIEDRICH
IPC: F16K1/24
Filed: 1986-09-02
Abstract: A butterfly valve has a housing (1) with a spherically shaped sealing surface (40) and a closure member (4) rotatable and pivotable therein by means of an actuating rod (13) preferably with a guide slot (35). The closure member (4) comprises a support member (5), which is connected to the actuating rod (13) and which is mounted in the housing (1) via a universal joint (8, 9). On its front side the support member (5) is connected by pin(s) (18) to an elastically deformable valve disc (12) in the form of a flat dish with a base (14) and a rim (15) and preferably a sealing strip (16), which rim is directed towards the support member (5). The valve disc (12) is normally spaced from the support member (5) and is supported marginally relative thereto eg. by an annular bead (17). With the valve closed, a differential pressure, irrespective of which side of the closure member (4) it acts on, acts so as to augment the closing pressure. The fluid tightness of the closed valve is thus assured independently of the direction of action of the differential pressure. <IMAGE>

Title: Moulding a thermoplastics pipe coupling incorporating a pre-formed elastomeric sealing ring
Inventor: PRITCHATT ROBERT JAMES
IPC: B29C45/14
Filed: 1986-11-04
Abstract: The molten thermoplastics material is injected to flow longitudinally along the mould cavity, so that it moves across and cleanses a tail portion (22) of the sealing ring (20), which projects into the mould cavity to become embedded in the wall of the coupling. The wall cavity is defined between a pair of exterior mould blocks (e.g. 30), and separable mould core parts (42, 36) and (38, 44), between which are clamped a sealing ring at either end of the cavity. The mould blocks define the sprue (34), and a main runner (35) which discharges into the cavity, at the central cavity location (40) of an abutment (14, Figure 1) projecting inwardly from the coupling wall. Diametrical and branch auxiliary runners (60, 62, Figure 5) also discharge into the cavity at circumferentially spaced locations around the abutment, to ensure that the longitudinal flow is circumferentially uniform. Displacement of the tail (22) by the flow is restrained by mould pins (58), comprising a castellated part of mould end rings (52). <IMAGE>

Title: The electrochemical deposition of refractory metals
Inventor: KIESELAK ANDREW TERRY
IPC: C25D3/06
Filed: 1987-12-23
Abstract: Chromium or other refractory transition metal (e.g. Ta, Zr, Mo, Nb, W, Hf) is electrochemically deposited onto conducting substrate from an electrolyte comprising a complex cation dissolved in a non-polar aromatic solvent, the cation comprising a complex of the refractory metal and an organic Lewis base containing a Group Vb atom. The Lewis base is preferably a primary, secondary or tertiary amine. The aromatic solvent preferably has 2 or 3 aromatic rings but should normally have a melting point below 100 DEG C. The process of the invention avoids the need for the high temperatures required for electrodepositing refractory metal coatings from molten salt baths.

Title: Communication system
Inventor: LEE HOCK LOCK
IPC: H04L12/28
Filed: 1988-08-17
Abstract: A carrier current transceiver system (Fig 1) involves a protocol which, following the initiation A-B of a receive unit, establishes a space/time code B-C which ensures that any designated/initiated transceive unit recognises on receipt of the space/time code that it has been initiated and that at the end , C, of the space/time code the next bits C-D-- to be received form the commencement of a data transmission thereto. The system includes devices (DCD1-3) coupled via interfaces to a ring main (RM). The space-time code renders the transceivers more immune to mains-borne noise, the time interval corresponding to B-C being related to the expected interval between noise signals. <IMAGE>

Title: Fixing system, a blank incorporating the same and a wallet formed from the blank
Inventor: CHAMBERLAIN CHRISTOPHER RAYMON
IPC: A45C11/24
Filed: 1988-11-03
Abstract: There is a system for securing a first component 21 to a second component 1, wherein the first component 21 is provided with a slit or slot 22 and the second component is provided with a tab which has a neck 3 and a relatively enlarged head portion 4; wherein at least the second component 1 is formed of a resiliently flexible material; and wherein the relationship between the shape of the slit or slot 22 and the shape of the tab is such that as, in use, the head portion 4 of the tab is pushed through the slit or slot 22 some deformation of the head portion 4 occurs but as soon as the head portion 4 is fully through the slit or slot 22 the resilience of the material causes the head portion to re-assume its original shape, thus making difficult any subsequent withdrawal of the head portion from the slit or slot. The system is simple to produce and is effective. Also disclosed are a blank which incorporates the system, and a wallet formed from the blank. <IMAGE>
