Title: Centrifugal force sensitive switch for a motor vehicle
IPC: B60G17/019
Filed: 1971-04-19
Abstract: 1348407 Engine stop gear M VAN DEN BOSCH 19 April 1971 [26 Feb 1970] 22567/71 Heading F1K [Also in Division H1] A centrifugal force sensitive switch for motor vehicles comprises conducting liquid 4, two electrodes 3 and a displacer body 6. As the vehicle turns a corner, depending on the speed and radius, liquid 4 moves round to one side of the housing 1 and breaks contact. Displacer body 6, which is a screw which can be screwed to different depths, varies the level of liquid 4 to set the switch for different vehicles, road surfaces, etc. Liquid 4 is mercury and on top of it is a non-conducting layer of glycerol or transformer oil 5 for damping purposes. In a second embodiment, Figs.2, 3 (not shown) screw 6 is replaced by an eccentric 7 which may be rotated to vary the level of liquid 4. In all cases, the switch breaks the ignition circuit when the speed is too high. The electrodes may be above the surface in which case the switch makes a circuit, to a warning device, etc., when the speed is too high.

Title: Process for increasing the anti-knock characteristics of hydrocarbon oils
IPC: C10G35/06
Filed: 1937-08-18
Abstract: The anti-knock characteristics of gasolines are improved by reforming hydrocarbon oils of gasoline boiling-range in the vapour phase at 450-650 DEG  C. for a period of 2-20 seconds in the presence of a catalyst comprising a precipitated and calcined aluminium hydroxide free from occluded and absorbed salts and containing 5-10 per cent water.  The aluminium hydroxide is prepared by precipitation from solutions of aluminium salts, e.g. alums, aluminates &c., by the addition of ammonium hydroxide, caustic alkali, or alkali metal carbonates, or by adding dilute sulphonic acid to aluminates, the precipitate being washed and calcined at 400-500 DEG  C. 500 parts of aluminium sulphate are dissolved in 1500 parts water and the aluminium hydroxide precipitated by adding 5000 parts of a 20 per cent ammonia solution at 50 DEG  C.  The precipitate is heated for half an hour at 60 DEG  C., then washed, and heated first at 200 DEG C. and then at 400 DEG  C. in a stream of air.  A naphtha having a boiling range of 160-213 DEG  C. and an octane number of 18 is treated at 500 DEG  C. for about 20 seconds in presence of the catalyst thus prepared, and a product is obtained having an octane number of 54 and sulphur content 0,03 per cent.

[Classes 83 (ii) and 83 (iv)] Coiling ; rolling; spinning.-A heat or cold exchanging element is made by winding a strip of metal broadside on to a cylindrical body member, securing one edge of the strip to the body, and bending the strip outwardly about said edge. A ribbon 11 is fed progressively to a tube 10 about which it is coiled in a substantially flat position, and is then bent up into a position substantially radially of the tube. The ribbon passes upon engaging the tube beneath a roller 15 which is formed with a continuous or interrupted bead 20 which secures the edge portion 12 of the ribbon to the tube by indentation. The ribbon is bent into its final position by progressive engagement with a number of blades 27 which perform a spinning action on the ribbon, and reduce its thickness in the direction outwardly from the tube. The work may be cooled through passages 70. The tube is rotated between the centres of a lathe and is supported by rollers 23.

Abstract: 740,500. Recovering aluminium or its alloys from dross. ALUMINUM CO. OF AMERICA. Aug. 20, 1953 [Aug. 30, 1952], No. 22959/53. Class 82 (1). In the recovery of aluminium or aluminium alloy from aluminous dross, freshly skimmed hot dross containing no solid aluminous metal is introduced into a chamber provided with a non-oxidizing atmosphere containing at least 50 per cent aluminium chloride, the dross being agitated whilst its temperature is kept sufficiently high to maintain the aluminium or aluminium alloy in the liquid condition. The agitation may last up to 15 minutes and may be repeated up to 3 times. The non-oxidizing atmosphere may contain an inert gas such as nitrogen or argon, the aluminium chloride being obtained by vaporizing solid chloride before or after introduction into the chamber, or by introducing gaseous chlorine at a rate not exceeding 0.005 pound per minute per pound of dross so as to react with a small proportion of the aluminium or aluminium alloy. The chamber should not be more than 2/3 full of dross, and it may be so constructed, or fitted with a valve or vent, to allow a little aluminium chloride to escape. It may be stationary and contain mechanically operated paddles, or it may comprise a cylinder inclined at 30-60 degrees to the horizontal and rotated at 1-20 r.p.m. In the form shown, the chamber comprises a cylindrical container 2 with a cover 4, a refractory lining 6, a chlorinesupply pipe 12, and a tap-hole 14 for draining off liquid metal 52 from beneath the dross 50. The edge of the cover carries spaced ball-bearing units 10 which bear against a pressure plate 56 attached to a crosshead 58 with flanged lugs 60 to engage under the cover, this assembly being raised and lowered by the piston rod 64 of an air cylinder. The container 2 is carried by a turntable 18, a bearing 20 and the base 34 of a cradle in which it is clamped by a band 54. The cradle is supported on trunnions 36 on a main frame 44, and is tiltable by gearing 38, 40 operated by a crank handle 42 or by power. The vertical members 32 of the cradle carry extensions 66 serving as guides for the crosshead 58. The container 2 carries two tracks 22 for engaging three unequally spaced sets of rollers 24 on shafts 26, one set being driven by a motor and speed-reduction unit 30 to rotate the container when in its inclined position. Specification 370,694 is referred to.

A hermetically sealed semi-conductor device comprises a cup-shaped support, a semi-conductor wafer disposed within the support, an insulating sleeve within the support whose circumferential surface conforms with the inner surface of the support, said sleeve being metallized and soldered to the support, and an electrical connector passing through the sleeve to contact the wafer. In a specific embodiment, Fig. 1, a copper support 14 has a silicon body 18 on the bottom thereof with two contact electrodes 22 and 24 and two solder preforms 42 and 44 on either side of the wafer 18. A copper electrode 36 passes through insulating member 26 and contacts the solder preform 42 at 40. A lead-tin solder is used to coat the insulator 26 at 46 where it meets the support 14 and also about the electrode 36 at 48. In another embodiment (Fig. 2, not shown), the inverted-cup shaped insulator 26 is replaced by a cylinder which houses a large diameter electrical conductor. The support may be Cu, Ag, Al, Fe or alloys thereof. The insulator may be ceramic or glass, e.g. steatite, alumina, cordierite, porcelain, and lead or lead-borate glass. The contact electrodes may be larger than the adjacent surface of the semi-conductor. Multielectrode devices may be also constructed. The device may be heat treated after assembly at 500-600 F., so that the various contacts may be consolidated.

[Also in Group XVI] In the manufacture of rolled type capacitors comprising metal foil strips with intermediate strips of dielectric material, the dielectric and metal strips are fed jointly to one station where they are perforated and then along separate paths of unequal length to another station where they are torn at the perforations. Fig. 1 shows the capacitor comprising metal strips 2 and 4 and paper layers 1, 3 and 5 and Fig. 2 shows the production machine. The metal foils and intermediate layers are assembled together at 12 and fed along separate paths 19,17 and 18,15 and 16, and 14 (corresponding respectively to foil 2, paper layer 3, foil 4 and paper layer 5 of the condenser), through jaws 20, 21, guide 22 to split mandrel 26. The outer covering layer 11, corresponding to layer 1 of the condenser, is fed separately over guide roller 23, to join the other layers in guide 22. In operation, a gripper 27 moves axially to grip loose ends from guide 22 and draw them into position so that they may be clamped between the two portions of mandrel 26. When the winding operation is completed, the layers 12 are perforated by comb 35 and later jaws 20 and 21 close to tear the strips at the perforation. The torn ends of the foils and intermediate layers are staggered due to the different path lengths. The outer covering 11 is continued for a few more turns, and then a hinge 28, glue brush 29 and roller 30 operate to cut and fix the covering. The condenser is then removed and the operation repeated.
