Title: Reversible plough
IPC: A01B3/421
Filed: 1981-11-19
Abstract: A tractor-mounted reversible plough has a plough frame (15) which is pivoted with the aid of a turning cylinder (5) from the one working position into the other. At the same time the plough end is lifted by means of a pivot cylinder (14) so far that an adequate clearance remains between plough end and ground. For this purpose the turning cylinder (5) is formed as a hydraulic cylinder which can change over automatically in the The pivot cylinder (14) is connected to the hydraulic conduits (6) of the turning cylinder (5) and thus chargeable simultaneously with the latter. Due to the collaboration of the two cylinders (5, 14), favoured by a quantity divider arranged in the pressure conduit (8) or a constriction (9), the turning operation proceeds continuously. The pivoting in of the plough frame (15) and the turning operation advantageously overlap one another <IMAGE>

Title: Document display apparatus
Inventor: STERN MALCOLM
IPC: B42D9/02
Filed: 1983-08-19
Abstract: A copyholder has a cursor for assisting document transcription. The cursor is driven by a drive belt 14, via a drive peg and thence a mounting block 22 to which the cursor is fixed. The block 22 is slidable on a guide rod 24 secured on the copyholder by leaf springs 26. To change a document the cursor is swung from the display face, as shown. An abutment on the block 22 engages the rear face of the copyholder, moving the rod 24 rearwardly against an increasing spring force, and disengaging the peg from the belt 14. The cursor is stable in the position shown but the return movement is assisted by the springs and as they relax the peg re-engages the belt 14. Cursor control means controlling the stepwise movement of the cursor may comprise a light sensitive sensor moving with the cursor, and reading a program bar 42 which has light and dark markings representing the required line spacing. The user operates a switch to drive the cursor, and a signal from the sensor interrupts the drive when the cursor has been driven through one line spacing. <IMAGE>

Title: A unit for dispensing beverage
Inventor: HEDDERICK JOHN BARCLAY
IPC: B67D1/08
Filed: 1983-09-21
Abstract: A unit for dispensing beverage has one or more pressure vessels 4 each having an outlet 11 for communication to a dispensing tap 15. Each vessel 4 accommodates a flexible bag 18 containing the beverage having gas in solution. The vessels 4 are pressurised through connection 16 by an air compressor in the unit or from an existing fluid line and this pressurisation serves to ensure dissolution of the gases in the beverage and also to expel the beverage from the bags 18. The beverage is normally sealed in the bags prior to loading into the pressure vessels and the pressure of dispensing may burst a membrane in the port 19 to permit the flow of beverage from the bag. Alternatively the coupling of the pipe 20 with the port 19 may break the membrane for dispensing. There is a refrigeration system 9 with cooling coils 7. <IMAGE>

Title: Safety closure for containers
Inventor: BEKKERS HENRICUS ANTONIUS MARI
IPC: B65D50/04
Filed: 1982-05-11
Abstract: A safety closure for containers comprises an assembled combination of an inner cap (103) housed in and surrounded by an outer cap (102). The inner cap (103) is provided along its outer circumferential surface or skirt portion (104) with a series of first teeth (106), the inner depending skirt portion of the outer cap (102) is provided with a series of second teeth (107) which can be brough in engagement with the first said teeth (106) by means of a relative coaxial movement of the inner and outer caps. The safety closure can be unscrewed from the container or screwed upon the mouth of the container respectively only by exerting upon the outer cap (102) a downward pressure causing the said teeth (106 and 107) to become interengaged, whereafter the inner cap (103) can be turned. The downward pressure upon the outer cap is resiliently resisted by means of spring elements or lips (118) depending from the upper wall portion (113) of the outer cap (102) which lips (118) are flexing against a wall portion (110) of the inner cap (103) which is located inside the container mouth and which converges annularly. The inner cap (103) is provided with a central cylindrical portion (111) rising up from said annulus (114), said lips (118) being operable in the space between the said cylindrical portion (111) and the inner mouth portion of the inner cap. Said central upper surface (112) of the inner cap (103) being rigidly and integrally connected to the remaining inner cap portion (110) in such a manner as to resist weight loads placed upon the safety closure even if the outer cap surface (113), surrounding the said central portion (112) may be slightly depressed thereby. The surface of said central cylindrical portion (111) being shaped as a central guide to the surrounding edge portion of the outer cap (102) during its coxial movement if downward pressure is exerted. It is preferred to have the surfaces of the upper portions (112, 113) of the inner and outer caps (103, 102) lying in nearly the same horizontal plane to render the safety closure a one piece outlook.

Title: Vibrational gyroscope
Inventor: CHURCH PETER DUDLEY
IPC: G01C19/5691
Filed: 1985-09-02
Abstract: A vibrational gyroscope is provided with a vibrating member in the form of a flexible annular shell extending from a flat flexible plate. In use, the flat plate is vibrated and excites radial vibrations in the lip of the annular shell. When the gyroscope is rotated about the shell axis, the nodes of these radial vibrations shift around the circumference of the lip, due to the action of Coriolis forces. The radial nodes of the vibrations in the plate shift similarly and their movement is detected by sensing means on the plate, giving an indication of the rotation rate.
