Patent GB-1416205-A (GB)
Title: Integrated circuit package
IPC: H01L21/56
Filed: 1973-05-18
Abstract: 1416205 Semiconductor devices INTERNATIONAL BUSINESS MACHINES CORP 18 May 1973 [14 June 1972] 23714/73 Heading H1K In a method for encapsulating one or more semiconductor chips 52 a conductive pattern 34 is formed on a surface of a carrier provided with conductive pins in apertures, a body 50 of plastics material is moulded over the pattern 34 and pins and the carrier is removed, leaving the conductive pattern 34 and pins bonded to the moulded body 50. The chip(s) 52 is bonded to the pattern 34 either before moulding of the body 50, in which case it is encapsulated within the body 50, or after moulding of the body 50; in which case it is attached as shown to the exposed surface of the pattern 34 formerly attached to the carrier. In both cases the exposed surface of the conductor pattern 34 (and, in the case illustrated, the chip(s) 52) is subsequently encapsulated by a further moulding process or by a pre-formed cover 60. Preferably the carrier is of stainless steel. The conductive pattern 34, e.g. of Cu, Ni or Ag, is electroplated through openings etched in a dielectric coating on the carrier, and also coats the pins. Prior to the moulding process a coupling agent is brushed on to the conductive pattern on the carrier to improve the ultimate bond between the body 50 and the pattern 34 and to ensure that the carrier parts from the pattern 34 more readily than the pattern 34 parts from the body 50. The composition of a suitable hydrolysed organo - silane coupling agent is specified. Preferably a heat sink 40 is incorporated in the body 50 during the moulding process in order that the effective thermal expansion coefficient of the body 50 in the vicinity of the chip 52 matches that of the solder reflow joints 56, 58 between the chip 52 and the pattern 34.

Patent GB-1010478-A (GB)
Title: Production of spinel catalysts
Inventor: SIDOROV IVAN PETROVICH
IPC: B01J37/00
Filed: 1962-06-21
Abstract: In a method of making spinel catalysts material for forming the catalyst is reduced in a powdered form at 225-250  DEG C. and after reduction is pressed into tablets.  Spinel is defined as a compound of formula XO.Y2O3 where X and Y denote different di- and trivalent metals and O represents oxygen.  The material to be reduced may be fluidized and reduction effected at atmospheric pressure.  After reduction, graphite may be added to the reduced material to facilitate tableting.  Comparative examples are given in which ZnO-Cr2O3-CuO and one or more of K2O, MgO and MnO2 are spinel constituents.

Abstract: 1398093 Administering medicines; inhalers HOECHST AG 22 May 1972 [22 May 1971] 23953/72 Headings A5R and A5T] A device for the administration of a pharmacologically active substance to an animal via the nasal mucosa and/or by respiratory absorption comprises bridging means connecting end pieces (3), 13 capable of gripping each side of the nasal septum of the animal, at least one end piece retaining the active substance whereby it will contact the nasal septum when the device is in position. As shown, each end piece 13 retains an absorbent pad 5 containing the active substance and the bridging means is a nose ring. Alternatively the substance in solid form is retained directly by the end piece. The active substance may be volatile so that it is absorbed during respiration and a further portion (12) of the substance may be held in the nose ring so that it may be licked by the animal. The end pieces may (Figure 111) pass through a pierced nasal septum or the bridging means (Figure V) may comprise an interengaging button and ring which passes through the septum. Suitable materials for the device and active substances are listed.

Title: Improvements in or relating to transporters having loading platforms supported by independent wheel units
IPC: B60P1/02
Filed: 1946-08-13
Abstract: 621,580. Vehicle fitting for loading. WHITEHEAD, R. M., and MITCHELL, S. S. C. Aug. 13, 1946, No. 23982. [Classes 78 (iii) and 78 (iv)] [Also in Group XXXII] A transporter vehicle in which a platform 41, container or other load carrying means, is supported at its ends by separable wheeled frames has axle units comprising wheels 3 mounted by stub axles 2 in a transverse body member 1 having a single vertically disposed lifting jack mounted centrally therein. The .lifting jack comprises a cross-bar 21 at the lower end of a vertical tubular member 20 which may be raised or lowered by rotating the central screwed column 23 secured at the top to the bell-shaped member 24 and engaging with the sleeve 22 secured in the top end of said member 20. Rotation of the screwed column 23 is obtained by turning one or both the hand-wheels 32, having sprocket wheels 33 at their lower ends coupled by chains 34 with integral sprocket wheels 28 and 29 keyed to the base of the bell-shaped member 24. To transport a load the cross-bar 21 is lowered and engaged with hook-like extensions 40 attached to the loaded platform 41. The cross-bar 21 is then raised until the conical spigots 38 are located in socket holes 42 thus permitting the platform to be rigidly secured to the body member 1 by depressing bolts 36 against springs 37 and engaging them in threaded holes 43. The central lifting jack may then be slacked to remove the load from the cross-bar 21. The process is reversed to unload the axle units, one of which may form part of a power-driven vehicle and be so modified to accommodate the drive-shafting to its wheels.

An expansion bolt comprises a male shank 3 and a female sleeve 8 formed with co-operable conical portions of different conicities, the conical portion of the shank being screwthreaded so that, in use, rotation of the shank causes the sleeve to expand. The sleeve may be slit longitudinally, preferably along its full length, and have means to prevent rotation initially which may be longitudinal ribs 12 as in Fig. 1, or tongues 21 as in Fig. 2 (not shown) extending longitudinally towards the bolt head. The sleeve may have a cylindrical bore 10 at its inner end, or may have a portion there whose cross-section is rectangular, oval, triangular or ribbed. The sleeve may be of aluminium or zinc alloy. The threads on the bolt comprise flanks 7 at right angles to the bolt axis forming a sawtoothed thread. The bolt may have a hexagonal headed end 4 or a screw threaded one. The bolt may be capable of engaging the sleeve to a limited extent e.g. by the provision of a quarter turn of a thread for ease of transport etc. A compressible stop 14 may be interposed between the bolt head 4 and workpiece 13, the stop collapsing as the bolt is tightened, and the thickness of the stop being equal to the desired axial movement of the bolt into the sleeve. The stop may be of synthetic plastic and may serve as a washer or gasket after tightening of the bolt. The stop may be integral with the bolt.

Title: Method of and apparatus for line-printing
Filed: 1963-06-18
Abstract: 979,608. Electric selective signalling. HITACHI Ltd. June 18,1963 [June 20,1962),No. 24269/63. Heading G4H. Line printing apparatus for printing in a variable line pitch comprises a synchronizing pulse generating pattern which rotates in synchronism with the printing types 2 to produce pulses with a variable interval between pulses. In Fig. 1,the pattern consists of lines 5 on a drum 4, the pitch between the lines varying linearly along the drum. The lines 5 are detected photoelectrically by a head 7, 8, the position of which along the drum 4 is adjustable to vary the interval between pulses. A mark 5<SP>1</SP> on drum 4 produces a start-printing signal from a photoelectric reading head 10,11. The pulses from heads 10,11 and 7, 8 are fed to a unit 12 to energize electrostatic printing heads 3 at the appropriate times in accordance with input information 15. The arrangement enables various mechanical errors to be corrected for, and for the distance between the lines of print to be varied. Additional means (not described) are provided to keep the ratio of the speeds of type drum 1 and recording sheet 17 constant during operation with a given pitch between printed lines. The printing may alternatively be done by electromagnetic printing hammers and the reading heads may be magnetic or be brushes sensing electrically conducting regions on drum 4. The drum 4 may be replaced by a patterned disc, maybe with curved strips. Each column of type may include several complete sets of type members.
