Patent GB-1302876-A (GB)
IPC: B01J27/057
Filed: 1969-12-04
Abstract: 1302876 Oxidation of olefines ROHM & HAAS CO 4 Dec 1969 [13 Dec 1968] 59246/69 Heading C2C [Also in Division B1] Olefins are oxidized in the gas phase at an elevated temperature in the presence of oxygen and a catalyst comprising cobalt molybdate fused with one or more of arsenic telluride, bismuth telluride or antimony telluride, the composition also containing at least 0À5 wt. per cent of a solid sublimable molybdenum compound (see Division B1).

Title: Improvements in or relating to phonograph with radial arm
Inventor: NORRIS ELWOOD GRANT
IPC: G11B3/085
Filed: 1970-12-15
Abstract: 1298226 Radial arm gramophone E G NORRIS 15 Dec 1970 [15 Dec 1969] 59443/70 Heading G5R In a gramophone using a pick-up assembly of the type described in Specification 1,298,225 which comprises a pick-up unit 16 slidably mounted on an arm 17 which can be pivoted between a rest position and a position over the gramophone turn-table, the unit and arm are controlled by a single cam member to operate in a single record playing mode. Operation of a push button switch 60 energizes cam drive motor 48 momentarily and during this period the motor drives cam disc 40 which via cam member 45 closes switch 64 connected in parallel with switch 60 so that the motor drive continues. Vertical pin 66 now engages part 67A of a member 67 made fast with the mounting spindle of the pick-up arm assembly so that the arm 17 is rotated to its record playing position over record 10 on turn-table 13. Thereafter tip 34A of shaft 34 rides up cam member 43 and when it reaches its uppermost position shaft 34 has rotated member 17B of the pick-up arm about member 17A to a position which is free of pick-up unit 15 which has thus rotated to move its stylus into playing contact with the record. At this time cam member 45 opens switch 64 and the cam motor drive ceases. At the end of record play a magnet 28 on the pick-up head actuates reed switch 27 again energizing motor 48 and this again stays energized through the action of switch 64. As the shaft 34 is lowered by cam member 43 the arm member 17B again rotates about member 17A lifting the pick-up from the record so that an endless cord 30 is engaged by a lug 15A on the pick-up unit via a longitudinal slot in member 17B. Drive wheel 34B on shaft 34 now engages the inner surface of cam member 44 so that shaft 34 is rotated, rotating pulley 31 to reel the pick-up member back to its initial position at stop 67. Thereafter vertical pin 91 engages part 67B of member 67 rotating shaft 34 and bringing the arm 17 back to its initial position. Finally cam member 45 opens switch 64 returning the assembly to its initial position. This return can be initiated at any time during play by operation of push button 6D. Lever 80 forms a pause control to interrupt playing of the record. On being moved vertically it rotates twin arm 84 about pivot 85 whereby arm 84B engages the cam surface 90A of a cam block 90 on the cam disc 40 to rotate this anticlockwise and arm 84A pivots motor 48 so that its drive wheel 50 is disengaged from the cam disc periphery. The rotation of the disc causes shaft 34 to ride down the leading edge of cam member 43 so that pick-up member 15 is rotated out of engagement with the record and the cam drive motor is energized ineffectively via cam operated switch 64. On lowering the lever the motor engages the cam disc and drives this to the position occupied before the lever was operated in which the pick-up re-engages that part of the record from which it was raised.

Abstract: 1355060 A nickel-magnesium zeolite W R GRACE & CO 23 Dec 1971 [23 Dec 1970] 59916/71 Heading C1A [Also in Divisions B1 and C5] A synthetic faujasite has a silica : alumina ratio of at least 3 : 1, nickel and magnesium ions and a sodium cation content of less than 4% and can be prepared by subjecting a Z-14 US type zeolite to ion exchange with a mixture of nickel and magnesium cations in aqueous soln. of pH 2 to 7 and then calcining the ion exchanged zeolite at a temperature in the range 750‹ to 1650‹ F.

Title: Iris Diaphragm Combined with a Filter.
Inventor: ARMBRUSTER EUGEN
IPC: G03B9/08
Filed: 1968-12-17
Abstract: 1,190,710. Iris diaphragms. R. RODENSTOCK [trading as OPTISCHE WERKE G. RODENSTOCK]. Dec.17, 1968 [May 15, 1968], No.59977/68. Heading G2A. An iris diaphragm comprises a number of pivoted blades, one of which has a partially transmissive portion 3, e.g. a circular opening covered by a grey filter. The movement of this blade about a pivot 1 is controlled by a pin 2 engaging in a cam slot (12) in a diaphragm-adjusting ring (10), Fig.2, (not shown). All the other blades have the same outline shape as this blade, but are without a filter, and are controlled by another cam slot (11). The two cam slots are shaped so that on rotating the adjusting ring (10), the blades first close down, in the normal way, to minimum aperture. The filter 3 is out of the light path, and the edge 4 of the blade of Fig. 1 helps to form the aperture with the other blades in known manner. Because of the shape of the cam slots, further rotation of the ring (10) causes the aperture to open again suddenly by several stop values, while at the same time the blade carrying filter 3 swings inwardly, so that the filter lies on the optical axis. Still further rotation of the ring closes the aperture down again, the filter remaining in the light path. Thus the equivalent of. an additional range of stop values below the normal minimum aperture is obtained.

The ring 10 is urged into sealing engagement by springs 11 and is mounted on the stern tube by a secondary seal 9 which allows the ring to tilt in operation. In a double seal arrangement, Fig. 2, freely rotatable intermediate rings 12<SP>1</SP>, 12<SP>11</SP> are disposed between associated rings 40, 41 and 42, 43 made of stainless steel, the axially outer ones of which being held by rings 2<SP>1</SP>, 2<SP>11</SP> mounted on a common support on the stern shaft while the axially inner ones are held by rings 10<SP>1</SP>, 10<SP>11</SP> which are urged apart in opposite directions by springs 46 and flexiblymounted by secondary seals 9<SP>1</SP>, 9<SP>11</SP> in a common liner 31.

Title: Sulphuric acid concentration
IPC: C01B17/88
Filed: 1978-09-21
Abstract: An aqueous sulphuric acid containing calcium and possibly iron, titanium and/or other impurities is concentrated by evaporation in the presence of generally some 2-5% by weight of a microcrystalline material serving to hinder the deposition of calcium-containing scale. Particularly suitable is the monohydrate of ferrous sulphate precipitated from the acid (when the latter contains iron impurity) at concentrations higher than that at which calcium scale is normally encountered. The process can be operated by adding this precipitate as retrieved from the filter of a subsequent evaporation stage, or by contriving its formation in situ by taking the evaporation stage in which the calcium precipitates to a much higher concentration, say at least 38% by weight. Acid from the production of titanium dioxide by way of the sulphate can readily be concentrated in this way without scale deposition.

Title: Glazing vehicle windscreens
IPC: B60J10/02
Filed: 1979-09-19
Abstract: A windscreen mounting arrangement for a motor vehicle comprises a plastics and/or rubber extrusion having parts 5 and 6 defining channels 7 and 8. Channel 7 grips the flange 14 surrounding the windscreen opening and the windscreen glass 70 is fitted into the channel 8 a stiffening member 74 being placed in a groove 24. The part 5 has a metal reinforcing carrier 9 which is compressible to a limited extent but substantially inextensible. It therefore resists tension which may be applied to the mounting arrangement during or before fitting. The arrangement is made slightly oversize and then compressed into the opening. This enables the glass 70 to "float" slightly in use, and reduces stretching of the rubber at bends in the windscreen opening. <IMAGE>
