Filed: 1963-05-14
Abstract: 997, 319. Detecting displacement photoelectrically. VYZKUMNY USTAV OBRABECICH STROJU A OBRABENI. May 14, 1963[June 5, 1962], No. 19144/63. Headings G1A and G1M. A scale for indicating the movement of a machine comprises two rows of equal sized transparent and opaque areas, the transparent areas of one row being opposite the opaque areas of the other and vice versa. A lamp 1 illuminates the scale 2, behind which are two screens 4, 6 carrying respectively slots 3, which are spaced by a distance equal to twice the length of an area, and 5 which coincide with the rows of areas. Light passing through the slots 5 energizes separate detectors differentially connected to give a trapezoidal output with movement of the scale 2, the output passing through zero each time the slots 3 coincide with boundaries of adjacent areas. The scale may be built up of sections joined only in dark areas or at places sufficiently distant from the boundaries of the areas not to interfere with the indication.

Title: Preparation of diarylamino-terephthalic acids and salts thereof
Filed: 1959-06-04
Abstract: 2 : 5-Diarylamino-terephthalic acids or metal salts thereof are prepared by simultaneously oxidising and saponifying a dialkyl 2 : 5-diarylamino - 3 : 6 - dihydroterephthalate and subsequently acidifying the reaction mixture to liberate the free acid, if desired.  The reaction is preferably carried out in aqueous or aqueous alcohol solution, using nitrobenzene-meta sodium sulphonate or air as oxidising agent and sodium, potassium, lithium, calcium or barium hydroxides as saponifying agents.  In examples a mixture of diethyl 2 : 5-dianilino-3 : 6 - dihydroterephthalate, ethanol, water, sodium hydroxide and nitrobenzene-meta-sodium sulphonate is refluxed, diluted with water and either acidified with hydrochloric acid to give a purple precipitate of 2 : 5-dianilino-terephthalic acid or the yellow disodium salt is precipitated by the addition of sodium chloride. The preparation of similar compounds, wherein the anilino groups are substituted by chlorine, bromine fluorine or iodine atoms or by methyl or methoxy groups, or are replaced by a - or b -naphthylamino groups is described.  Specification 828,051 is referred to.

Abstract: 1,165,854. Encapsulated electronic assemblies. FRIDEN Inc. 25 April, 1968 [15 May, 1967], No. 19518/68. Heading B5A. [Also in Division H1] An assembly of integrated circuit clips 10, Fig. 3, embedded in a block 20 of cast encapsulating material with their surfaces, provided with terminal pads (16), Fig. 1 (not shown), exposed and the terminal pads interconnected by conductors 28 overlying the surface of the block 20, is formed by casting encapsulating material in a mould in which the individual clips are arranged with their surfaces against one face of the mould and subsequently removing the one face of the mould to expose the terminal pads of the clips so that conductors can be formed on the surface of the block. As described the clips comprise a substrate (12), Fig. 1 (not shown), of semi-conductor material having operative elements 14, e.g. transistors, diodes and resistors, and terminal pads 16 formed thereon. Each clip may be bonded to a metal pin 22 of, e.g. gold-plated alloy of nickel and iron, acting as a heat sink. The clips are located face downwards on a glass plate (32), Figs. 6-8 (not shown), backed by a mirror (31), using a microscope (38), the required positions of the clip and the mould walls on the plate having previously been marked, e.g. by etching, on the surface of the plate. The clips and mould walls are held in position before encapsulating by an adhesive, e.g. a silicone material in a solvent or carnauba wax. The encapsulating material may be a ceramic, e.g. magnesium carbonate or a silicon dioxide material or an epoxy resin which may have a mineral filler. After the material has set and the glass plate removed, the interconnection conductors may be applied by sputtering alternating insulating 50, 56 and conductive 53-55, 58, 59 layers, Fig. 13, of silicon dioxide and aluminium on to the block, the sputtered materials being limited to selected areas by photo-resist techniques. Alternately insulating areas of glass and conductive areas of cermets may be applied as paint or ink through screen stencils.

Title: Reversible motor control for vehicle wheel spinners

Abstract: 1358621 Control of A.C. motors STEWART-WARNER CORP 27 April 1972 [29 April 1971] 19657/72 Heading H2J [Also in Division H1] A control arrangement 36 for a reversible electric motor 14, in a wheel spinner device 10 including a drive wheel 16 movable with the motor 14 by handle 22 against the bias of a spring 24 to engage the vehicle wheel 11, includes power switches 37 for energizing the motor only when wheel 16 engages wheel 11 and reversing switches 39 prevented from operation unless wheel 16 is disengaged from wheel 11. A manually rotatable shaft 140 has a cam 138, whose periphery 136 engages a switch operating arm 120 for the reversing switches 39, e.g. switch 96 with operating button 130, and a locking plate 154 co-operating via recesses 158, 160 with arm 174 of a locking member or slide 92, having a biasing spring 176 and another arm 173 engaging the switch operating aim 76 of the power switches, e.g. microswitch 62 with button 86. A lever 38, pivoting with the motor 14 and drive wheel 16, engages arm 173 of slide 92, when the motor is in its non-loaded (disengaged) position, to operate power switches 37 and cut-off the supply to the motor as well as moving the slide 92 to its upper position, against spring 176, in which the locking plate 154 is released for rotation from arm 174. Thus the reversing switches 39 are operable by manual rotation of shaft 140, with slide 92 in its upper position, via cam surface 136 and arm 120. When handle 22 moves motor 14 to reengage the wheels 16 and 11, the lever 38 drops and spring 176 pulls slide 92 downwardly to re-engage arm 174 in recess 158 or 160 of locking plate 154 and prevent any rotation of shaft 140. Also arm 173 releases switch operating arm 76 and the normally closed power switches 37 complete the motor supply circuit. Fig. 8 shows the circuit diagram including power switches 37 and reversing switches 39, and the associated arm 173, lever 38 and cam 138 referred to above, arranged such that motor 14 is energized whenever handle 22 is depressed so that drive wheel 16 engages wheel 11 and is de-energized whenever handle 22 is released, so that arm 173 opens switch 37. Rotation of shaft 140 reverses current flow through the armature windings (terminals 186, 184) upon operation of switches 39, whilst current flows in the same direction through the field winding (terminals 188, 189) in all instances.

Regulation, automatic.-Stoppage of a fluid - pressure operated regulator 8 centrally of any contact is ensured by a notch device 9 cooperating with a bell crank 10 which is centred by a spring 11. If the regulator 8 is not resting centrally on one of its contacts the lever 10 is deflected from its normal position and opens a valve 12 to supply fluid to the piston 6, thereby centralizing the regulator. The lever 10 can control contact in the circuit of magnets used to move the valve 12.
