Patent GB-476307-A (GB)
Title: Improvements in or relating to thermally-operated temperaturelimiting devices
IPC: H01R13/713
Filed: 1936-06-03
Abstract: 476,307. Thermal switches. GREEN, G. E., and GREEN, Q. F. June 3, 1936, No. 15538. [Class 38 (v)] In a device in which rise in temperature causes the melting of an alloy in a cavity e and the subsequent release of a plunger h which, for example, may eject a connector d off its pins, a spring-pressed pin f <1> in the cavity normally engages a hole p in the hollow plunger h and at least one of the co-operating surfaces of the plunger and pin is inclined so that, on melting of the alloy the plunger begins to move under the action of its driving spring j and in so doing presses down the pin out of its locking position. When the plunger has moved still further, a spring g returns the pin f<1> to its original position in which it is resoldered. The device is then reset by pressing in the plunger h, the pin f being forced through a narrow slot o in the end of the plunger and snapping into the hole p. Specification 432,053 is referred to.

Title: Method of making connecting parts of semi-conducting devices or the like.
IPC: H01L23/485
Filed: 1969-03-25
Abstract: 1,217,293. Semi-conductor devices. SONY CORP. 25 March, 1969 [25 March, 1968], No. 15549/69. Heading H1K. A contact bump on a semi-conductor device is produced by securing a metal electrode to a surface of the device, forming a metal layer over the surface and over the electrode, the metal of the layer having an affinity for the metal electrode but not for the surface, forming a metal bump over the electrode, and heating to a temperature at which the metal layer fuses and is aggregated into the bump. As shown, a region 12 of a silicon IC is contacted by depositing a glass layer on an existing glass or silicon dioxide coating to form an insulating layer 13, photoetching to form a window 13a and depositing an electrode 14 comprising a layer 14a of aluminium coated with a layer 14b of titanium and a layer 14c of nickel, Fig. 2A. A layer 15 of tin is deposited over the surface of glass layer 13 and electrode 14, Fig. 2B. A metal mask is placed on the surface and lead is vapour deposited to form a contact bump 17<SP>1</SP> which is provided with a surface layer 18 of silver if desired, Fig. 2C. The mask is then removed and the arrangement is heated to melt layer 15 which aggregates into the contact bump 17 due to surface tension, Fig. 2D. The excess lead portions 17a<SP>1</SP> (Fig. 2C) which form round the contact bump due to the gap G between the mask and the device are simultaneously aggregated into the contact bump. Any excess tin remaining on the surface may be removed by coating with a flux, e.g. resin, and heating. The electrode 14 may comprise a single layer of A1.

Title: Improvements in or relating to a device for automatically controlling the discharge of material from a hopper
Inventor: CHRISTL MANFRED
IPC: B65G47/00
Filed: 1964-04-15
Abstract: 997,803. Feeding sand. LEIPZIGER EIBENUND STAHLWERKE VEB. April 15, 1964, No. 15623/64. Heading B8S. Sand is supplied from a hopper 12 past a sliding valve 5 into a container 1 whence it is discharged in predetermined quantities into a mould. The supply of the sand from hopper 12 into container 1 past valve 5 is governed by weight 3 carried by rope 2 secured to a block 4 and the block also serving as an indicator for the scale 7. The movement of block 4 is controlled by member 6 secured to slide 5 and the operation is governed by switch 11 and by a time switch not shown. Operation.-As shown, material in container 1 has risen to its greatest height 9 and operates a time switch which closes sliding valve 5. At the same time the member 6 moves leftwards with the valve 5 to release block 4 ready for movement. Discharge then takes place from container 1 into a series of moulds the material being discharged in predetermined quantities so that weight 3, which has been released by member 6 to fall on to the top of the material in the container, gradually moves downwards till the material in the container approaches its bottom-most level and at the same time block 4 moves leftwards and finally impinges on and actuates the valve 11. This operates two things. It causes slide valve 5 to move rightwards to open the bottom of hopper 12 to permit the flow of material into container 1. Secondly it causes member 6 to move block 4 rightwards and maintain it at its endwise position thus positioning it for the next cycle of movement. Thirdly, it operates a timer switch which governs the movement of slide 5 so that at a predetermined time slide 5 is moved leftwards, shuts off the flow of material into container 1 and by means of member 6 frees block 4 for the next downward movement of weight 3. The apparatus is now set for a further discharge of predetermined quantities from container 1.

Title: An improved method of and apparatus for manufacturing cast mass-produced parts
IPC: B22D5/02
Filed: 1952-06-20
Abstract: 744,238. Casting-machines and processes. ZUNCKEL, B. June 20, 1952 [June 20, 1951], No. 15639/52. Class   83 (1). Mass production of castings is characterized in that metal or other molten material is cast in continuous sequence into mould cavities cooled on one side by a cooling plate forming one side of the cavities and along which the moulds move, the inlet sides of the cavities being temporarily closed in succession after filling. The cavities 1, Figs. 2 and 3, may be formed in a metal or ceramic plate 2 and communicate with the outlet 4 of a pot 3 containing molten metal. The bottoms of the cavities 1 are closed by a fixed water-jacketed plate 5 which is not so long as the plate 2 so that when this is reciprocated the castings fall, or can be pushed down, out of the cavities 1 which are beyond the end of the plate 5. A metal band 6, which may be endless, may be arranged between the plates 2, 5 to move with the former if the metal has not solidified when the plate 2 moves. To keep the plate 2 at the best temperature it may be heated or cooled as required. Cores may be pushed through the cooling plate into the castings just formed and be withdrawn when these solidify and before the plate 2 advances. In a modification the molten metal enters the mould cavities 12, Fig. 4, in the movable plate 11, upwardly at a point in advance of the cooling plate 13 through a channel 14 which may lead from a container 3 at a higher level. The channel 14 may be cooled or heated by means at 15. Alternatively the plate 11 may rotate about a vertical axis so that the cavities 12 always move in the same direction past the channel 14. The mould plate may be of cylindrical form 19, Fig. 6, mould cavities 21 being formed in its periphery which is engaged by the outlet 22 of a molten metal pot 23 arranged as shown or on top of the cylinder. The cooling plate 24 is of part cylindrical form and in addition a heating or cooling plate 27 may be used. An endless metal band 31, Fig. 8, not shown, may be arranged between the cylinder 19 and cooler 24 and the cooler 24 may be omitted provided the band is cooled as by fluid spray. The cooler also may move, e.g. the plate 5, Fig. 4, or 24, Fig. 6, may move in a direction perpendicular to the plane of the drawing. Blanks so formed are stated to have an oriented crystal structure, due to the unilateral cooling, which renders them suitable for hot or cold working by deformation perpendicular to the crystal orientation.

Abstract: 1,259,957. Drying photographic sheets. KODAK Ltd. March 27, 1969 [April 1, 1968], No.15661/68. Heading G2A. A device for clamping one edge of a photographic sheet 2 on to a support surface 1 for drying comprises a bar 4 which is naturally curved so that it is convex towards the sheet, and which has means for releasably securing it to the support so that it is deformed against its natural curvature to lie flat along the edge of the sheet. The bar 4 may have a U-section, and has a hook 6 at one end which hooks on to the support 1. At the other end is a slidable hook 10. The clamp is first hooked on to the support at the end 6, then the other end is forced down against the support so that the bar is deformed out of its natural convexity to clamp the edge of sheet 1 against the support, and then the hook 10 is pushed inwards to latch under the support. The support surfaces 1 may be part of a cylindrical drying drum within which heating means are disposed.
Patent GB-810501-A (GB)
Title: Improvements relating to the carboxymethylation of primary and secondary amines
Filed: 1956-05-22
Abstract: Primary and secondary amines are carboxymethylated by adding an aqueous solution of glycollonitrile to an aqueous solution of the amine at a pH of at least 12 and maintaining the mixture at a temperature between 85 DEG  C. and the boiling point at a pressure of 1-5 inches of mercury.  Examples show the production of ethylene diamine tetracetic acid from ethylene diamine, N-dodecyl-iminodiacetic acid and N-dodecyl-glycine from dodecylamine, N:N - di - hydroxyethyl - glycine from diethanolamine and iminodiacetic acid and nitrilotriacetic acid from glycine.  The required pH is produced by addition of a base, e.g. sodium, potassium, calcium, barium or lithium hydroxide or tetra - ethanolammonium hydroxide, and the product may be obtained as a salt with the base, or as the free acid after acidification.  The process may also be applied to ethylamine, chlorethylamine, butylamine, cyclohexylamine, propylene diamine, diethylene triamine, triethylene tetramine, piperazine, amino-propionic acid, amino-isovaleric acid and amino-phenylpropionic acid.

Title: Liquid cooled eddy current coupler device
Inventor: MUNSON CHESTER LEROY
IPC: H02K49/04
Filed: 1962-04-26
Abstract: 999,336. Electromagnetic couplings. LOUIS ALLIS CO. April 26, 1962, No. 15952/62. Heading H2A. The eddy current drum of an eddy current coupling, brake or dynamometer is cooled by passing a liquid coolant axially along the outer surface of the drum from an annular manifold plate which closely surrounds the drum. The eddy current drum 28 is rigidly attached to shaft 16 and encloses a field member which is attached to shaft 12, power is supplied to coil 21 of the field member through slip-ring assembly 20 and the enclosing poles 22, 23 are interdigitated. Outside drum 28, which is made of magnetic material, an annular manifold member 57 is situated and attached via pipes 52, 58 to an external coolant supply box 60. The manifold plate is shaped so that at the edges it is very close to the drum surface and coolant entering under pressure through ports 55 is squeezed axially along the drum through clearances 63, 64 into sump chamber 65 thus cooling the drum. In order to ensure that all the coolant goes to the sump two baffle systems 61, 62 and 72, 73 working in conjunction with the flanges 70, 71 keep the liquid away from bearings and the like. The annular manifold plate may be modified by the addition of another close clearance portion at each edge, these being separated from the first close clearance portion by an annular channel which has a number of ports in it communicating with the sump, Fig. 2 (not shown). In this case the extra baffles at the ends of the drum are not required since the amount of coolant ejected from these additional ports leaves only a small amount of fluid to axially traverse the edge clearance. If two field members are used, Fig. 3 (not shown), two annular manifold plates are used and in cases where the field members are stationary, these form the manifold plates and the fluid is fed in centrally between them and passes out axially under them, Fig. 4 (not shown). In all modifications air flows through the coupling and cools the inside surface of the drum.
