Title: Improvements in or relating to the Cylinders of Internal Combustion Engines.
IPC: F02F1/10
Filed: 1916-03-24
Abstract: 105,087. Napier & Son, D., and Rowledge, A. J. March 24, 1916. Cylinders, construction of and cooling.-Cylinders of aluminium or its alloys are cast in dies, either in one with, or separate from their heads. Steet liners to valve boxes D<1>, Fig. 2, are incorporated in the casting and may be split longitudinally, except at the seating D. Longitudinal T-shaped flanges B have the sheet aluminium jacket C attached to them by welding or screwing. A platform A<2> for carrying the valve-gear joins the valve-spindle guides. The sparking-plug socket E is also embedded in the casting, and in order that the casting may be withdrawn from the mould when the socket is in the position shown in Fig. 7, a recess A<6> is formed in the mould behind it and becomes filled with metal to be afterwards removed, or the mould or die carries a plunger which fills this recess and is withdrawn in the direction of the cylinder axis. The joint between the socket and the sheet-metal jacket is made with a ring of dermatine F. A number of cylinders may be cast together, either separately from. or integral with, their heads, which are alsc in one piece. There is a longitudinal fin such as B, Fig. 2, between each two barrels. In an alternative form, Fig. 13, the cylinder barrel and valve-chest are cast together with a separate cover made in two pieces A<9>, C<3> having a water space between them. A cylinder head cast in dies may be used with a barrel cast in sand, or with a cast-iron barrel. The mould for the cylinders shown in Figs. 2 and 7 comprises two dies only, the joint being on the axes of the passages D<1>.

Title: Process for dyeing wool and cellulose fibres in the presence of levelling agents
IPC: D06P1/613
Filed: 1963-02-04
Abstract: Dyeings on wool or cellulose are levelled using one or more polyalkylene glycol ethers of polyphenols resulting from the copolymerisation of monomeric phenols containing polymerisable unsaturated groups with copolymerisable monomers or by the polycondensation with formaldehyde of monomeric phenols in which at least either an ortho- or para-position to the phenolic hydroxyl group is substituted.  Among the specified polymerisable phenols are vinyl-allyl- and 3, 4-butemyl-phenol, mono-vinyl and monoallyl ethers of dihydroxy-benzenes and the monoacrylic acid ester of resorcinol. The copolymerisable monomers should not contain functional groups with acidic hydrogen atoms, those specified being styrene, vinyl chloride, vinyl esters, vinyl ketones, vinyl ethers, acrylonitrile and acrylic acid esters. Phenols suitable for the polycondensation products bear inert substituents, e.g. alkyl, cycloalkyl, aryl, aralkyl radicals, chlorine and bromine atoms, those specified being p-octyl-, nomyl-, dodecyl-, cyclohexyl-and chloro-, phenol.  These phenols may be condensed with almost dry paraformaldehyde or with solutions of trioxan or formaldehyde.  The alkylene oxide used is mainly ethylene oxide but propylene oxide, butylene oxide, styrene oxide, epichlorhydrin or cyclohexane oxide may also be used; sufficient must be used to make the final product water-soluble, e.g. 10-100 mol ethylene oxide per hydroxyl group.  The levelling agent is preferably added to the dyebath but may be applied after dyeing has taken place.  In the examples wool is dyed with 1 : 2-metal complex acid dyes and viscose and cuprammonium rayons are dyed with direct and vat dyes in the presence of a number of specified levelling agents.

Title: Improvements in or relating to projectile fuzes
IPC: F42C15/24
Filed: 1951-07-27
Abstract: 709,699. Projectile fuzes. ANSTALT FUR DIE ENTWICKLUNG VON ERFINDUNGEN UND GEWERBLICHEN ANWENDUNGEN ENERGA July 27, 1951 [Aug. 8, 1950], No. 4481/53. Divided out of 708,351. Class 9(1) Fuze operating on impact of projectile and provided with means for arming the fuze by inertia comprises a striker 3 fixed to a projecting head 4 and a detonator carrier 7 slidable in the fuze body 1, the striker and detonator carrier being locked by a safety device while the projectile is at rest. The safety device comprises an elastic member and an annular inertia mass 11 and means for interlocking the mass and the detonator carrier. A stud 16 projecting from the annular mass 11 engages a groove 17 in the carrier, the groove being provided with a zig-zag branch and a short, blind branch 17a. On firing the projectile, the mass 11 sets back due to inertia compressing the spring 15 arid the stud 16 slides along the groove, friction and the zig-zag motion causing a delay in the rearward movement. When acceleration of the projectile ceases, the spring 15 moves the mass forwardly so that the stud becomes locked in the branch 17a of the groove, thus permanently arming the fuze. Specifications 620,875 and 708,351 are referred to.
Patent GB-304493-A (GB)
Title: Improvements in or relating to electric cables
IPC: H01B9/02
Filed: 1928-02-13
Abstract: 304,493. Cohen, E. S. Ali-. Feb. 13, 1928. Cables with auxiliary conductors.- A method of applying a conducting covering to the insulated cores of an electric cable, or to the cable as a whole, consists in drawing the core, after the insulation has been applied and while it is still somewhat heated, through a fine powder of metal or other conducting material, such as carbon black. The invention is particularly adapted for use with a cable insulated and protected with a covering of the substance known under the Registered Trade Mark " Karetnja, " which is described in Specification 103,824, [Class 70, Indiarubber &c.]. With such a cable, the lead sheath or armouring is dispensed with, and the layer of conducting powder serves for earthing purposes or for securing a favourable distribution of the dielectric stress. In applying the powder, the core is drawn through the conducting powder as it leaves the pressing, wrapping, or forcing machine, so that the particles stick to the Karetnja which is still heated. Cables with bituminous or other kinds of wrapping can be submitted to a similar process.

Title: Improvements in and relating to apparatus for the treatment of sewage and the like liquids
IPC: C02F3/28
Filed: 1923-02-15
Abstract: 193,407. Girard, A. Feb. 15, 1922, [Convention date]. Plant. - The gases from a septic tank are absorbed in the surrounding earth into which they may be passed directly through apertures or pipes leading from the upper part of the tank or indirectly through a chamber having apertured brick walls or through a trench filled with stones and covered with earth. Fig. 1 shows a septic tank 1 divided into three compartments by walls 5, 6, from which the gases pass through pipes 7 to a trench 8 filled with stones and covered with a layer 9 of earth. The liquid from the septic tank passes through a siphon 10, and a reservoir 11 to a contact bed 13 containing materials such as turf or coke supported on a perforated plate 14. The treated liquid is discharged siphonically from a tank 18 communicating with the contact bed through an opening 16. A chamber 24 is in communication with the contact bed in such manner that with a rise of liquid level in the contact bed a float valve in the chamber 24 is opened to admit water from a pipe 22, and thus cause the siphon 18 to come into operation. The Specification as open to inspection under Sect. 91 (3) (a) comprised also a modification, shown in Fig. 3, (Cancelled), in which a septic tank is provided with pipes 2, 3, through which gases are passed into the atmosphere. The liquid from the septic tank is passed through a tank 4 containing earth over a layer of stones. Grass or other vegetables may be planted on the earth. A suitable shed prevents the entry of rain-water. This modification is not described in the Specification as accepted.

Title: Improvements in or relating to variable electrical inductor devices
IPC: H03K25/00
Filed: 1960-02-09
Abstract: 929,000. Inductors; automatic control. PHILIPS ELECTRICAL INDUSTRIES Ltd. Feb. 9, 1960 [Feb. 12, 1959], No. 4548/60. Classes 38 (2) and 38 (4). [Also in Groups XIX, XXXVIII, XXXIX and XL (c)] An inductance device variable by remote control comprises a core 1 of soft magnetic material carrying one or more coils 2 and a linked core member 3 of highly retentive magnetic material carrying a winding 4, pulses supplied to winding 4 affecting the magnetisation of core member 3 according to their number, amplitude and duration and so causing variation of the inductance of coil 2 or of the coupling between two coils on core 1. There may be an automatically operating device arranged to cut off the supply of pulses when the inductance of coil 2 reaches a maximum and so prevent reversal of the direction of magnetisation in core 3. Alternatively pulses may be applied to a winding arranged to produce transverse magnetisation in core 3. For remote control of a radio or t.v. receiver the pulse generator 13 (Fig. 3) produces positive and negative pulses according to which of photo-electric cells 14 or 15 is illuminated. Supply of pulses is stopped by feedback through conductor 22 when a given value of inductance of 17 is achieved. The apparatus may be used for counting pulses or for automatic control of the state of a device 20 (Fig. 4) recorded by a measuring instrument 21 which, on a given deviation, sends a control signal to pulse generator 19 inducing it to emit positive or negative pulses as appropriate. Instead of using positive and negative pulses the pulse supply may be switched to the appropriate one of two oppositely coiled windings on the core 3.

Title: Improvements in crystal filters and circuits therefor
IPC: H03H9/54
Filed: 1956-02-14
Abstract: 806,654. Crystal filters. GENERAL ELECTRIC CO. Feb. 14, 1956 [Feb. 14, 1955], No. 4607/56. Class 40 (8). [Also in Group XL (c)] A crystal filter comprises a coil 38, a crystal 40 and a capacitor 50 connected in series, the coil and the capacitor being series-resonant at the signal frequency and the crystal being cut to resonate at this frequency. An output circuit, e.g. the grid circuit of a valve 54, is connected across the capacitor 50. At the signal frequency the series-resonant circuit constitutes a low resistance in series with the crystal. The Q of the filter depends upon the value of this resistance and may be controlled by the addition of a resistor 52 of suitable value. The coil 38 forms part of a transformer M which is adjusted to provide critical coupling. The effect of the capacitance of the crystal holders 42, 44 is reduced by an inductance 48 selected to form with the holders a parallel resonant circuit at the signal frequency. The circuit may be used for producing a continuous wave from a series of repetitive bursts of several cycles of the desired wave. The bursts may be analysed into a continuous wave of the desired frequency plus unwanted sidebands. A circular crystal with bevelled edges is preferably used in order to reduce spurious responses to a negligible amplitude for a frequency region within which the sidebands of the bursts have any appreciable amplitude.

Abstract: 1,165,604. Gun sights. F. ARENE, and M. DERAMOND. 31 Jan., 1967 [9 Feb., 1966], No. 4657/67. Heading F3C. [Also in Division G2] A telemetric telescope has two optical tracks A and B vertically shifted relative to each other and each producing an image of the field observed by means of a single catadioptric objective 13, the aiming axes of the two tracks converging at a predetermined distance from the telescope and the telemetric images being observed together with the image produced by a separate, third, optical system C through a common eyepiece 22. Images from the tracks A, B and C are focussed on the surfaces of prism 21 and glass blade 25 respectively which are engraved with micrometric scales of which the mark (4) in the high magnification telemetric field of view, Fig. 1 (not shown), registers with a point in the image (38A) formed by track A, while the mark (5) in the low magnification field of view of system C registers with the same point in the image (37) formed by track C. The image (38B) formed by track B only coincides with image (38A) when the telescope and the firearm to which it may be attached, are given the necessary elevation. The said predetermined distance corresponds to the " fighting distance " for which images (38A), (38B) coincide, without adjustment of elevation, on the mark (4). Other marks on the scale represent different object distances. In a modification, the landscape is anamorphosed in the vertical sense by an afocal prism system inserted between prisms 11 and 12 of tracks A and B. By this means, the slight displacement from coincidence of images (38A), (38B), Fig. 1, due to parallax between tracks A and B is corrected.

Abstract: 724,799. Coating with metals. COMMONWEALTH ENGINEERING CO. OF OHIO. Feb. 20, 1953, No. 4832/53. Class 82 (2). Objects (e.g. golf-club heads) are plated by contact with thermally decomposable metal bearing gases at the decomposition temperature of the said gases, by a method in which the objects are conveyed along the length of a conduit that is divided into a plurality of compartments by resilient partitions that will yield to pass the objects being plated, but which will prevent any substantial passage of gas between the compartments of the conduit, with one compartment being supplied with a hot inert gas to bring the articles up to decomposition temperature of the plating gas, the next compartment being supplied with the decomposable plating gas, and the next following compartment being supplied with an inert cooling gas. The apparatus is shown diagramatically in Fig. 2 where the objects are mounted on an endless belt 12 and move successively through compartments 36 to 30 collectively denoted 16 being degreased, washed, pickled, washed, then dried in compartment 18. They are then heated in compartment 41, plated in 42, which is double-walled to prevent egress of poisonous gases, and cooled in compartment 43, all in non- oxidizing atmosphere and collectively denoted 17, Fig. 1. The top of compartments 41 and 42 may be made of glass to allow heating by infra-red lamps 47, 56 or induction heating may be used. The entrances and exits to compartments 41, 42 and 43 are protected by mechanical locks (Fig. 9) composed of resilient members 72 to 75 each divided vertically into two (72a, 72b, for example). The atmosphere of each compartment is therefore prevented from escaping, as the objects 10 pass through. Provision is made for supplying, and withdrawing, gases from each compartment. Coating metals specified are Ni, Fe, Cr, Mo, Co, Cu, Sb, Sn, Zn, Os, Ru.
