Patent GB-923308-A (GB)
Title: Improvements in or relating to protective systems for electrical equipment
Inventor: SHEWAN JOHN RICHARD
IPC: H02H11/00
Filed: 1958-04-28
Abstract: 923,308. Protective arrangements. NALDER BROS. & THOMPSON Ltd., J. R. SHEWAN, and S. W. ECKELT. April 28, 1959 [April 28, 1958], No. 13459/58. Class 38 (5). In an earthing arrangement for an apparatus 1, e.g. an electric drill, the main earth connection E1 is monitored by means of an impedance transformer T3. In Fig. 2 a contactor operating coil is normally energized by an auxiliary supply over earthing leads 2, 3 to the apparatus, so that failure of either lead causes the opening of the contactor contacts 7, 8 to disconnect the apparatus. This earthing circuit is connected by the transformer T3 to an earth loop comprising the main earth electrode E1 and an auxiliary earth electrode E2, so that any increase in the resistance of this earth loop is reflected by the transformer into the earthing circuit to cause the opening of the contactor. The turns ratio of the transformer is such that the resistance of the earthing circuit may be kept to a low value whilst enabling a higher resistance earth loop to be monitored. Fig. 1 (not shown), illustrates the application of the invention to the arrangement of Specification 727,966. In either arrangement the contactor coil and the auxiliary supply may be disposed in the earth loop. Reference is made to the use of a single impedance transformer in conjunction with the earthing circuits of several tools.

Title: Improvements in and relating to potters' moulds
IPC: B28B7/34
Filed: 1946-05-03
Abstract: 616,172. Making electro-deposited moulds. JOHNSON, E. J. May 3, 1946, No. 13516. [Class 41] [Also in Group V] A method of making potters' moulds includes the step of producing from an original model or from a plaster reproduction therefrom, an electrodeposited mould which serves for the production of large numbers of plaster moulds either directly or by way of an intermediate electrodeposited reproduction. In moulding, for example, a plurality of cups from an original model, a block in plaster or other suitable material is formed from the model and a block case is formed from the block. These three elements are normally kept in storage. From the case is formed a working lump d, from which is formed a wax block case e. The wax is rendered electrically conductive by inclusion of graphite within the wax composition or by superficial treatment with graphite. A copper working block f is made by electro-deposition on the wax case. A copper working case is electro-deposited on the inner surface of the block f from which it is then separated. The case is filled and mounted and from this case the final plaster moulds are produced. In a modification, a wax working block similar in form to the plaster lump d is used to produce an electro-deposited metal. case from which one or more working cases are produced by electro-deposition in two steps.

Title: Process for the manufacture of acetaldehyde, catalysts for use therein and processes for the preparation and regeneration of such catalysts
Inventor: TEBBOTH JOHN ARTHUR
IPC: B01J27/28
Filed: 1958-04-30
Abstract: Acetaldehyde is manufactured by passing acetylene (or a gas containing acetylene) in admixture with at least 2 volumes of steam per volume of acetylene at 250-400 DEG C. over a catalyst comprising activated charcoal or carbon (surface area not less than 900 sq.m./gm. and containing below 0,03% Cu, Zn, Bi or alkali metals), impregnated with (on a dry basis) 0,1-0,3% Bi, 0,07-0,25% Cu, 15-25% H3PO4, and having a moisture content of 5-25% by weight.  It is preferred to remove diacetylene, vinylacetylene, alkylacetylenes and arylacetylenes as well as e.g. benzene and toluene present in the initial acetylene-containing gas by passage through activated charcoal and carbon which may be, at least in part, spent hydration catalyst (described above).  In examples, the feed gas contained (a) 10% acetylene, 6% ethylene, 20% methane, 2% CO2, 10% CO, 5% N2, balance chiefly H2; (b) similar to (a) except for the presence of (i) 0,6% diacetylene and 1,0% other acetylenics (actylene 9,3 or 11%) or (ii) 0,1% diacetylene and 0,2% other acetylenics (acetylene 10,2 or 10,0%), it being shown that in the case of (b) pretreatment of the gas with activated carbon improves the process with respect to the amount of acetaldehyde produced.  It is stated that the higher acetylenics and the aromatics may be separated from the charcoal or carbon by treatment with steam at above 100 DEG C.ALSO:A catalyst is prepared by impregnating an activated charcoal or carbon (which may have been completely dried) containing less than 0.03 wt. % of Cu, Zn, Bi or alkali metals and of surface area (measured by iodine absorption) of at least 900 sq. m./gm., with Bi and Cu salts and H3PO4 such that the product contains by wt. on a dry basis 0.1-0.3% Bi, 0.07-0.25% Cu and 15-25% H3PO4; and adjusting the moisture content of the product to 5-25, preferably 7-12 wt. %.  Preferably the charcoal or carbon is first impregnated with Bi nitrate (e.g. pentahydrate)/dilute HNO3, dried, then impregnated with aqueous Cu phosphate/H3PO4 and finally the moisture content is adjusted, optionally by drying to below 5 wt. % moisture and rehydrating.  It is preferred to (a) make the Cu phosphate/H3PO4 solution by dissolving a suitable Cu compound (e.g. oxide or basic carbonate) in H3PO4; (b) use impregnating solutions containing just sufficient water so that the solutions are completely absorbed by the charcoal or carbon.  The catalyst, used for the vapour phase hydration of acetylene to acetaldehyde, may be regenerated after exhaustion by impregnating with 0-0.2% Bi, 0.08-0.15% Cu and 2-10% H3PO4, all by weight on the dry weight of catalyst.

Title: Improvements in and relating to inductance coils
IPC: H01F17/00
Filed: 1932-05-13
Abstract: 400,693. Inductances. COLLE, V. G. VAN, and WARD & GOLDSTONE, Ltd., Frederick Road, Pendleton, Manchester. May 13, 1932, No. 13814. [Class 37.] A dual-range inductance coil comprises a solenoid form medium wave section and a sectionalized longwave part wound in bobbins or on formers, the inductance of the medium wave part being adjusted by varying the spacing between two or more turns of the solenoid inductance and the longwave portion being adjusted by varying the spacing between two or more of the bobbins or formers. A moulded former a carries a number of bobbins b reach having a winding b<1>, these windings being connected in series to form a long-wave winding. A further bobbin c may carry a coupling or reaction winding. Interposed between the bobbins are rings of rubber, leather, sponge rubber, guttapercha, or other resilient material. The upper end of the former a is shouldered and screw-threaded at a<4> to take an internallyscrewed ring d which bears on the uppermost bobbin c, so that by screwing up the ring d the bobbins can be adjusted relatively to one another until the total inductance of the winding has the desired value. The upper end a<5> of the bobbin a is reduced and screwed to take a former f on which is wound the medium-wave winding g. The end turns g<1> of this winding are spaced as shown and are adjusted towards the main part of the winding by a screwed device which is removed after use. After adjustment the turns may be fixed by a coating of cellulose compound &c. A cap h is provided and may hold a screening can j. The cap h may have a depending flange which serves to adjust the spacing of the turns g<1>. Instead of the screwed ring d, a pair of cams may be arranged close to the outside of the former at the ends of a diametrical rod so as to compress the bobbins against one another when the rod is turned, e.g. by a screwdriver. The cams may be clamped by a nut on the screwed end of the rod. The inductance may be arranged so as to be decreased on screwing up by winding one of the windings on the bobbins or part of the turns on the solenoid in a reverse direction. According to the Provisional Specification the core may be wound on a former of slightly compressible material, which may then be compressed or stretched to obtain the desired inductance value.

Filed: 1951-06-12
Abstract: Fluorine-containing compounds are obtained as a product of a reaction, absorption or solution between hydrofluoric acid and aliphatic, aromatic and heterocyclic amines and aliphatic amides and their substitution products wherein the total number of carbon atoms is not less than 8 per molecule.  The products are characterized by insolubility in water and miscibility in hydrocarbon grease and oil. Representative of many compounds specified for treatment with hydrogen fluoride are 2-oleyl-4-methyl-4-oxymethyl - 2 - oxazoline, 2 - pentyl - 4,4 - bis - (hexano-oxymethyl) - 2 - oxazoline, 2 - heptadecylimidiazole, ethylene bisiminodiacetic acid, phenyl morpholine, 1-hydroxyethyl-2-heptadecenyl glyoxalidine, n-octadecane amide, 2-ethylhexylamine, didecylamine, tri - n - amylamine, phenyl ethanolamine, 3-phenyl-propylamine, o-dimethylamino-ethyl-p-octyl phenol and octylphenoxyethoxyethyldimethylamine.  Treatment is preferably effected in the anhydrous condition.  Generally vapours of the acid are bubbled through the liquid or liquified amino compound. Quantities of hydrogen fluoride remaining associated with the amino compound may range from 0.5 to 20 per cent by weight of the treated material.  The compounds are used singly, mixed or in admixture with oils, greases and mineral spirits to lower the electrical resistance of mechanical joints between conductors (see Group XXXVI). Specifications 632,487 and 719,304 are referred to.

Title: Improvements in internal combustion engines of the sleeve valve type
IPC: F01L5/10
Filed: 1936-05-16
Abstract: 462,427. Valves; cylinders. HOWALD, W. May 16, 1936, No. 13950. Convention date, May 16, 1935. [Classes 7 (ii) and 7 (vi)] In sleeve-valve engines with inlet and exhaust ports near the dead-centre positions of the piston, the bore of the cylinder and the outer surface of the sleeve valve are made smaller at the hotter end of the working chamber, so that they assume a cylindrical shape when they have attained the working temperature. Fig. 1 shows a two-stroke engine cylinder 1 and sleeve valve 3 with the radial dimensions enlarged so as to indicate the formation of the cylinder and sleeve walls when cold, the cylinder walls sloping inwards to the exhaust ports a and being of larger diameter at the lower end, which is formed with the inlet ports b. The sleeve valve is correspondingly tapered inwards to a reduced diameter above the exhaust ports. In an engine having the inlet ports at the upper end and exhaust ports at the lower end, the sleeve and cylinder are tapered near the lower end in the neighbourhood of the exhaust ports, and also to a less degree adjacent the inlet ports. The sleeve valves are made thin so as to be pressed outwards by the cylinder gases, and may have slightly less thermal expansion than the cylinders. The upper end of the sleeve valve, which overlaps the cylinder head, may be reduced in section to give a better sealing effect, and may be formed so as to expand to a larger diameter than the cylinder when the sleeve is removed. Such reduced part may be cylindrical, as shown in Fig. 5, or conical, or curved in various ways, for example as shown in Fig. 11, which also shows an enlargement at the edge of the sleeve. Specifications 425,060 and 445,882 are referred to.
Patent GB-1462426-A (GB)
Title: Labelling machines
IPC: B65C1/00
Filed: 1974-03-29
Abstract: 1462426 Labelling ATO Inc 29 March 1974 [29 March 1973] 14030/74 Heading B8F A container labelling machine has a rotary transfer device comprising label holding pads 15 mounted on a rotor 10 for movement between a normal extended position in which each pad travels in a path tangent to a label picker 12, adhesive applying means 14 and container supporting means (not shown), to a retracted position, means yieldably holding the pads extended, and means operating in the absence of a label on a pad to retract the pad as it passes the adhesive applying means. In Fig. 2, each label is picked off a magazine 205 by a rotary suction picker 207 which puts the loading edge of the label opposite an air nozzle 209 which blows the label into a nip between driven roll 208 and the adjacent pad 15, to which the label is then held by vacuum. The label passes driven gumming rolls 294, and then to an applying station where containers are fed by a turn screw conveyer (not shown). At this station, vacuum is cut off and pressure supplied to the pad. Each pad is mounted on a member 54 pivotable about shafts 58, see also Fig. 7, on twin spiders 36, and is normally held extended by spring 68. The spiders are rotated on shaft 22 by worm gears 200, 202 through differential gearing 192, 194, 196 enabling the relative positions of the rotor and picker mechanism 207, 208 to be varied manually. Valve plates 150, 152 control the admission of vacuum and air pressure to each pad as it rotates. Each member 54 contains a sleeve 52, shown in Fig. 7 but not mounted on the rotor, in which a piston 186 is slidable. When vacuum is applied to the pad and a label is in place, the vacuum above the piston raises it as shown. In the absence of a label, the piston falls, whereby follower 188 contacts a fixed arcuate cam 180 on base-plate 18, which pivots the member and pad inwardly as the pad passes the gluing rolls 294, and closes a valve mechanism 128, 106 to cut off the vacuum. The supply of vacuum to the picker is controlled by a switch operated synchronously with the rotor drive, and by a photoelectric device responsive to the presence of a container so that no label is picked if a container is absent. A stripper is provided to remove any glued labels that remain on the pads after the label applying station. The rotor is adjustably tiltable to apply labels to containers with non-vertical walls.
