Patent GB-1300568-A (GB)
Title: Improvements in and relating to integrated circuits and electrical connectors therefor
Inventor: STOREY JOHN JOSEPH
IPC: H01L23/485
Filed: 1969-12-20
Abstract: 1300568 Semi-conductor devices PLESSEY CO Ltd 19 Nov 1970 [20 Dec 1969] 62189/69 Heading H1K Metallic interconnections on an integrated circuit are anodized to form an insulating coating. An integrated circuit is covered with a dielectric layer 12 containing windows 14, 16 and a metal layer 18, e.g. of aluminium, is deposited over the circuit. A photoresist layer 20 is produced on the layer 18, and partially removed to expose areas of the metal layer corresponding to the desired interconnections. The exposed metal is anodized to form an anodic film 22, and the resist layer removed. Using the anodic film as a mask, the remaining portions of the layer 18 are removed by etching, leaving the interconnections covered with the anodic film. Such a method is said to prevent defects which could be caused by " pinholes " in the resist layer. A capacitor may be further formed using the interconnections by applying a second metal layer, using the same method, to the interconnections, and even a third metal layer with anodic films between the layers.

Patent GB-2004079-A (GB)
Title: Improvements in or relating to pressure-fixable toners
IPC: G03G9/093
Filed: 1978-09-11
Abstract: This invention relates to pressure-fixable toners for use in electrophotography. Problems have arisen with previously known toners due to the fact that they are made of tacky materials and so tend to either stick to each other (blocking) or to carrier particles if they are part of a two component developers, or to the photoconductive layer being developed. The present invention provides a pressure-fixable toner having particles each comprising a central core of a pressure-fixable resin and at least one colour pigment, and an outer coating of a blocking preventing component adhesively held to each core. The blocking preventing component is preferably in the form of a fine powder of ZnO, Al2O3, SiO2, TiO2, Fe3O4, clay or carbon black and prevents the toner particles from sticking to each other or any other material until pressure is applied.

Patent GB-2013304-A (GB)
Title: Rack and pinion assembly
IPC: F16H19/00
Filed: 1979-01-22
Abstract: In a rack and pinion assembly a rack bar (1) is supported in engagement with a pinion (4) by a resilient plastics moulded bearing member (6) of saddle shape which straddles the rack bar on its side remote from the rack (3) and preferably opposite to the region of engagement between the rack and pinion. The bearing member (6) straddles the rack bar to restrain lateral displacement of the bar in the direction of the pinion axis (4a) and can be pre- loaded upon assembly with the rack bar to constantly bias the rack (3) into engagement with the pinion. Inter-engaging projections and recesses between the bearing member (6) and the housing (2) serve to locate and restrain the bearing member (6) from displacement relative to the housing (2) and the bearing member is seated in a recess (10) which additionally restrains its longitudinal displacement relative to the housing (2). Location of the bearing member (6) in the housing (2) may be achieved by deformation of that member. <IMAGE>

Patent GB-2029249-A (GB)
Title: Model steam locomotives
IPC: A63H19/10
Filed: 1979-08-30
Abstract: A model steam locomotive is driven by an electric motor M and includes a valve gear 8-11 regulating the steam control valves of the steam cylinders 7, the electric motor is coupled to the axle 19 of a set of driving wheels 1 via a drive shaft 18, which is permitted a limited amount of axial float and is coupled to the axle by a gearbox 20. Axial movement of the drive shaft is produced by interaction between the gears 21, 22 of the gearbox and is controlled by coil springs 24, 25 disposed on the shaft at opposite ends of the gearbox. These axial movements result from changes in the amount and direction of the torque applied to the gearbox by the electric motor and are transmitted to the model valve gear by an axially movable rod 28. Hence the configuration of the valve gear is continuously changeable, thereby providing for more realistic operation of the model. <IMAGE>
Patent GB-2040279-A (GB)
Title: Process for coating electric light source envelopes
IPC: H01J9/24
Filed: 1979-09-07
Abstract: In a process for coating envelopes of electric light sources with an inorganic pigment, e.g. electro-statically, the pigment grains of the coating are coated with an organo-metallic glass precursor compound before applying the pigment to the envelope, thus enabling the formation of a very thin glass layer on the surface of the pigment grains; the composition of this layer is such that its softening point is lower than the softening point of the envelope and achieves a good adhesion between the envelope and the pigment without damage to the pigment in the subsequent heat treatment in which the precursor is transformed into glass. The glass precursor compound is formed in a solution containing organic solvent(s) in which selected organo-metallic and inorganic compounds have been dissolved. A suspension is prepared from the solution and the pigment, followed by evaporation of the solvent and heat treatment.

Patent GB-2063595-A (GB)
Title: Monitoring electric motors
IPC: G05B23/02
Filed: 1979-11-15
Abstract: Failure of a tachogenerator TG driven by an electric motor DCM and providing an output used to control operation of the motor may lead to runaway of the motor. Circuitry for detecting this fault operates in dependence upon the tachogenerator output and a driving voltage applied to the motor, and may be arranged to provide an abnormality indicating response if the tachogenerator output has a value outside a predetermined operating range (e.g. less than Vr2) at a time when the driving voltage is within a preselected working range (e.g. greater than Vr1). In another embodiment the absolute value of the difference between signals representing the tachogenerator output and the driving voltage is compared with a threshold. The response provided may be used to initiate measures for checking such runaway of the motor. <IMAGE>

Title: Methods and apparatus for preventing or minimizing vibrations and noises in machine tools such as bandsaw machines
IPC: B23D55/00
Filed: 1980-10-31
Abstract: Noise from bandsaw machines has been a problem in the past, for which no real solution has been available. It has now been surprisingly found that the vibration (and thus the noise) of an elongate flexible member can be prevented or reduced, by periodically changing the length thereof, by periodically changing the tension thereof, by periodically changing the Young's Modulus (E) and/or by periodically changing the density thereof. The driven or driving wheel of a bandsaw blade may be provided with axially extending peripheral grooves.

IPC: C08F2/20
Filed: 1980-12-01
Abstract: A process is described for making sterically stabilised non-aqueous dispersions of composite polymer microparticles, in which (1) monomers including at least one crosslinking monomer are polymerised in an aqueous medium at a temperature at least 10° higher than the glass transition temperature of the polymer to be formed, in the presence of a block or graft copolymer stabilising agent, under conditions such that there is at no time present a separate monomer phase, (2) further monomers, not including any crosslinking monomer, are polymerised in the dispersion thus obtained, the presence of a separate monomer phase again being avoided, and (3) the microparticles are transferred from the resulting dispersion into a non-aqueous medium which is a solvent for the non-cross- linked polymer generated in (2). The microparticles are of value for incorporation into coating compositions the main film-forming constituent of which is compatible with the non-cross- linked component of the particles.
