Title: Improvements in or relating to ball-joints particularly for steering linkages in motor vehicles
IPC: B62D7/16
Filed: 1964-11-06
Abstract: 1,043,778. Ball joints. J. ULDERUP. Nov. 6, 1964 [Dec. 19, 1963], No. 45335/64. Heading E2F. In a ball joint, suitable for steering linkages in motor vehicles, an elastomeric seal 8 is compressed to provide self-adjustment of the joint. The seal may be made from cellular polyurethane and the sliding surfaces 9 may be of the same material, but homogeneous, or may be of polyamide or P.T.F.E. The surfaces 9 may be impregnated with molybdenum disulphide. The cells may be filled with gas to promote damping of oscillations.

Title: Valve arrangement for hydraulic steering systems
IPC: B62D5/08
Filed: 1971-09-29
Abstract: 1357129 Vehicle steering DANFOSS AS 29 Sept 1971 [2 Oct 1970] 45341/71 Heading B7H [Also in Division F2] An hydraulic servomotor steering system comprises a steering ram 8 supplied by a pump 1 via a control valve 4 and a manually operable valve 16 for rendering ram 8 short-circuited so that the vehicle is self steering under tow, for example. In the position of valve 16 of Fig. 1, the ram 8 is operative and is protected against sudden shocks from the road by the ball-check valves' 11-14. Thus if piston 9 is suddenly forced to the left, excess fluid from the left-hand chamber will pass valve 11 into relief duct 10 while fluid passes valve 14 into the right-hand chamber. Valve 16 (Fig. 2) comprises a spool 19 which is engageable with a fixed seat 21 and a seat 23 which forms part of a nut 36 on an axially fixed screw 40. Manual rotation of screw 40 clockwise will allow spool 19 to move to the right. When excess pressure exists in duct 7 spool 19 remains in contact with fixed seat 21 and fluid flows through groove 35, ball-check valve 13 and into duct 6. When excess pressure exists in duct 6, spool 19 is urged to the right against seat 28. Fluid now flows through groove 35 to valve 14 and into duct 7.

Title: Fragrance-releasing packages and folded cards
IPC: A45D34/00
Filed: 1971-10-21
Abstract: 1370282 Boxes; container closures 3 M UNITED KINGDOM Ltd 21 Oct 1971 [24 Sept 1970] 45640/70 Headings B8P and B8T [Also in Divisions A5 and B6] The invention relates to packages from which a fragrance is released when they are opened or manuipulated, the fragrance originating from the contents of microcapsules which are coated on to one or more surfaces of the package and are 'ruptured by frictional forces when that surface is moved (by opening or manipulating the package) relative to an adjacent surface. Numerous embodiments are described including various box-like packages and stoppered bottles. In Fig. 3, the microcapsules are coated on to the flap 24 of the "flip-top" package; in Fig. 4 a face 38 of a plastic casing carries the microcapsules which are ruptured when the lid 30 is removed. Figs. 7 and 6 (not shown) depict the necks 62 and stoppers 64 of screw topped bottles in which the microcapsules are carried on a washer 66 and are ruptured by the unscrewing movement. That shown in Fig. 7 has an adhesive coating 68 on the seal 66 as well as a coating 70 containing the microcapsules of aromatic material. The adhesive in coating 68 is also contained in microcapsules and is released when the stopper is screwed on and provides lubrication which prevents rupture of the aromacontaining microcapsules. Fig. 5 (not shown) depicts a package wrapped in plastics foil having an opening strip on a part of which the microcapsules are applied and on another part is a pressure sensitive coating. The coated part passes through a restrictive band, e.g. of paper, plastic or metal when the strip is removed thus causing capsule supture.

Title: Position determination system
IPC: G01S19/46
Filed: 1962-12-04
Abstract: 951,908. Radio position finding. RAYTHEON CO. Dec. 4, 1962 [Jan. 25, 1962], No 45848/62. Heading H4D. A system for finding the position of a moving object equipped with means transmitting a stable frequency signal, comprises, in addition to the object, a pre-surveyed reference site including a plurality of spaced receiving stations whose locations are known and each of which is equipped with means producing a stable reference signal and means measuring the phase difference between the signal received from the moving object and its reference signal, the phase difference measurements being made simultaneously at all the receiving stations a number of times in succession to provide sufficient information to solve for the position of the moving object. In the embodiment described the moving object comprises an artificial satellite 2, transmitting the stable frequency signal from an antenna 12 as a single side-band modulation such that its wavelength may be of the same order as the satellite's distance. The signal from the satellite is received at a pre-surveyed reference site 1, with co-ordinates Xr, Yr and Zr, by four receiver arrangements 3, 4, 5 and 6, wherein at four close instants of time as determined by a timer 9, the phase of the received satellite signals, after demodulation, is compared in each of the receiver arrangements with that of a locally generated reference signal. The phase difference, Rrs, thus found for any one measurement is related to the satellites co-ordinates, Xs, Ys and Zs by an equation:- where ##rs is the bias phase difference between the satellite and reference signals and is unknown, but assumed constant over the period of the four successive measurements. The four successive sets of measurements yields sixteen simultaneous equations with sixteen unknowns. The sixteen values of Rrs are converted into a digital form and passed to a computer 8 where the four sets of co-ordinates of the satellite are calculated. The four sets of co-ordinates are then transmitted after redigitizing, to be picked up by the satellite on antenna 13. If a fixed frequency difference exists between the satellite signal and the locally generated signal then eight successive sets of four simultaneous phase difference measurements will have to be taken. In an extension of the system the satellite retransmits the four sets of co-ordinate signals from antenna 13 for reception by a receiver arrangement 10 at an unknown position. The receiver arrangement 10 also receives the signals from satellite antenna 12 and compares their phases at four successive instants with that of a locally generated signal to determine the position of the receiver arrangement 10.

In between the coated portions of the base support 16 apertures ensures the ready draining-off of water from the grass pile. As shown, a resilient underlay 14 is interposed between the textile base 16 and a top drainage layer 8 to improve the tread properties of the grass. The synthetic grass together with the textile base and underlay are laid in sections as shown in Fig. 1 and are secured to the ground base by locking members 22 inserted in channel-shaped metal sections 12 having bent-out teeth 20 laid on concrete support ribs 4.
