IPC: B01J23/00
Filed: 1971-12-21
Abstract: 1376326 Olefin isomerization catalysts DAICEL Ltd 21 Dec 1971 [22 Dec 1970] 59255/71 Heading B1E [Also in Division C5] Catalyst for use in the preparation of 5- alkylidene-2-norbornene by isomerization of 5(1-alkenyl)-2-norbornene is substantially free from molecular oxygen and water and comprises, preferably consists solely of, alkali metal supported on alumina having a surface area greater than 1m<SP>2</SP>/g, preferably greater than 10m<SP>2</SP>/g. The alkali metal may be selected from lithium, sodium, potassium, rubidium and caesium; the alumina may be alpha-, beta-, gamma-, delta-, eta- or kappa-alumina. The catalyst, which may contain from 0.01 to 0.5 parts by weight of alkali metal per part by weight of alumina, may be prepared by a procedure wherein alumina free from molecular oxygen and water is dipped into or sprayed with an alkali metal solution or suspension and the resulting composite is dried; prior to contact with the solution or suspension, the alumina may be rendered free from molecular oxygen and water by heating at a temperature of at least 200‹C, preferably of from 300 to 800‹C. under reduced pressure or in an inert gas atmosphere. As exemplified, alumina which has been heated at 400‹C under reduced pressure is added to a solution of alkali metal in liquid ammonia, which solvent then is removed by distillation to provide sodium (Example 1) or potassium (Example 3) supported on alpha-alumina having a surface area of 23 m<SP>2</SP>/g or rubidium (Example 5) supported on (unspecified) alumina.

Filed: 1973-12-31
Abstract: 1404300 Making carden joint spiders or helicopter rotors; extruding H STARKIER 31 Dec 1973 [16 Jan 1973] 60306/73 Headings B3P and B3A A component with radially projecting arms is made by squeezing a billet between platens 1, 2 to cause radial flow between parallel columns 5 followed by final forging of the deformed billet. The platens carry die plates 4, 8 of which one retains the columns and the other has bushes 9 through which the columns slide. The bases of the columns are tapered 10 to facilitate ejection of the deformed billet by an ejector 11. The upper die plate 8 is convex to facilitate the radial flow of the billet. The arms produced by the metal flow between the columns have a rectangular cross-section and are shaped after ejection between dies in the final forging. The component may be a carden joint spider or a helicopter rotor.

The cable system is completed by a cable 89. Above the tables is a cooling-ring 64, on a trolley 65 so that it may be moved transversely into operative position above either of the tables. Alternatively a separate cooling-ring may be provided above each table. The cooling-rings may be supplied with molten metal from a tiltable ladle on a separate gantry or on the machine framework. At least one carriage may have relatively large adjustments of its position on the cable to permit casting of bars of any desired length within the maximum vertical traverse of the tables.

Patent GB-2011324-A (GB)
Title: Improvements in or Relating to Pneumatic Tyres
IPC: B60C5/16
Filed: 1978-12-14
Abstract: A pneumatic tyre having a pair of axially spaced tyre beads (4) at least one of which has a circumferentially extending toe is provided with primary air relief means e.g. grooves (10) extending between the axially inner and outer surfaces of the toe to prevent the toe effecting a seal with the rim when the tyre is fitted to a non-matching wheel rim. The tyre bead (4) having the toe may have secondary air relief means (23) axially outboard of the primary air relief means to prevent the tyre bead (4) effecting a seal with a bead retaining flange when the tyre is fitted to a non-matching wheel rim. When fitted to a non-matching wheel rim and inflated, the tyre deflates by air leaking through the primary air relief means and, where provided, the secondary air relief means (23). When the tyre is fitted to a matching wheel rim and inflated the toe is received in a groove (Fig. 3 not shown) in the wheel rim so that the primary air relief means is closed preventing loss of air. The primary air relief means may alternatively comprise criss-crossing grooves (Fig. 6 not shown) or holes extending through the toe. <IMAGE>

Title: Steering control apparatus for trailers
IPC: B62D13/00
Filed: 1979-03-13
Abstract: Steering control apparatus for articulated road trailers (14) comprises a first coupling device which is mounted between the trailer (14) and tractor (13). The coupling device has a first part (1) mounted for movement with the tractor (13) and a second part (14) pivotally mounted on the trailer and connectable to the first part (1) for rotation therewith on rotation of the tractor (13) relative to the trailer (14).

The first and second parts of the coupling device disconnect to allow relative rotation therebetween when rotation of the first part relative to the trailer succeeds a predetermined amount. <IMAGE>
Patent GB-2044697-A (GB)
Title: Valve Assembly for Power Assisted Steering Gear
IPC: B62D5/083
Filed: 1979-03-20
Abstract: A valve assembly for a power assisted steering gear has two valve elements (2 and 12) interconnected by a torque rod (8) and which are relatively rotatable for controlling fluid flow through the valve. A clutch mechanism (15) is provided between the elements (2 and 12) formed by a pair of diametrically opposed balls (16) located in radially extending bores (17) in the element (12). The balls (16) engage with respective seatings (18) in the element (2) and are biased by a mechanical "C" shaped spring (19) into such engagement. During relative rotation between the elements (2 and 12) the balls (16) are displaced from their seatings (18) against the preloading of spring (19) to provide "feel" to such relative rotation. The element (2) is the input shaft of a steering gear and the element(12) is the tubular part of a valve component which is rotatable with a pinion of a rack and pinion steering gear. Alternatively, the spring (19) can be of annular or helical form to engage with the respective ball members, through pressure pads if required or individual springs can be provided for biasing each ball. <IMAGE>

Patent GB-2019181-A (GB)
Title: Improvements in and relating to fishing weights
IPC: A01K95/00
Filed: 1979-04-25
Abstract: There is provided a fishing weight having a hollow body in which a baited hook can be retained. The hook is retained until the weight hits the water, when the impact causes a retaining means to release the baited hook from within the hollow body. The hollow body is provided with spring 9 which holds means 7 and 8 in mutual engagement. Impact forces panel 2 rearwardly, compressing the spring and disengaging means 7 and 8, permitting panels 2 and 3 to separate and release the hook from the interior of the weight. Alternatively the fishing weight may contain a movable weight which is caused to move when the weight hits water plus causing engagement means to disengage to release the hook. <IMAGE>

Title: Control device for automatic door operator
IPC: E05F15/12
Filed: 1979-10-17
Abstract: A control device for an automatic door operator 13 includes a highly compact stop assembly employing a plurality of disc-type springs 70 confined within a housing and cooperable with a plunger 71; the assembly being fixed to one of a pair of adjacently disposed rotatable gears in the drive train of an automatic electro-mechanical door operating mechanism. The involved gears are disposed in overlapping relationship is, and the stop assembly is engageable a with the periphery of one of the gears in response to partial rotation of the other whereby to limit their relative rotation and limit door opening operation. The disc-springs are capable of producing impact resistance of a relatively high value and of sufficient magnitude to protect the mechanical drive train from expected overload forces. Adaptation of the disc-spring concept for the door stop permits an extremely compact stop device capable of being mounted within the limited confines of a header mounted or under-the-floor mounted housing for the operator mechanism, thereby satisfying desired esthetic requirements while avoiding operational defects prevalent with heretofore known hydraulic or pneumatic door stops. The door operator 13 is actuated by an electrical drive motor (not shown), initiated by a mat switch 16, through a gear train mechanism. <IMAGE>
