Title: Improvements relating to electric ignition means for internal combustion prime movers
IPC: F23R3/48
Filed: 1946-07-15
Abstract: 614,481. Jet propulsion plant. LUCAS, Ltd., J., and HUYTON, A. July 15, 1946, No. 21085. [Class 110 (iii)] In an internal-combustion prime mover or jet propulsion plant of the type having a plurality of air-jacketed combustion chambers arranged in annular form about a common central axis and interconnected by balancing pipes which put the chambers in communication with each other, the ignition plug is mounted in the balancing pipe. Two of a number of sheet metal combustion chambers a, which are mounted in annular form around a common central axis, are shown in Fig. 1. These combustion chambers are surrounded by air jackets b and connected by an airjacketed balancing pipe c. The air jacket of the balancing pipe is formed of two elbow fittings f, g bolted to the air jackets band connected together at their adjacent ends by an expansion joint consisting of a tube h sliding in sealing rings i. The fitting f is provided with a socket k in which the ignition plug d is mounted. It may also be provided with a second socket to support a pilot jet. The balancing pipe c consists of two parts, the ends of which are shaped to form an expansion joint between them. The outer ends of the balancing pipe are flanged for attachment to the air jackets b and to short hollow extensions c<1> which communicate with the combustion chambers a. The balancing pipe is also provided with openings for the ignition plug and pilot jet.

Title: An attachment device for mincing machines
IPC: B02C18/30
Filed: 1953-07-30
Abstract: 726,754. Grating and juice extracting. SATZINGER, G. July 30, 1953 [July 31, 1952], No. 21113/53.Class 28 (2). Juice is extracted from bulbous fruits, roots, herbs, &c. by attachments to a mincing machine 19 in which the usual cutting knives and perforated plate are removed and a shredding cylinder 5 is clamped thereto, to which a separate pressing screw 25 is added to squeeze the shreds and so extract the juice through a perforated extraction chamber 26, clamped to the shredder housing 18 by a ring nut 20. The fruit is swept round against the shredding projections of the perforations inside the the shredding cylinder by one or more twisted blades 12 rotated by the square shank 2 of the mincer. A housing 18 surrounds the shredder, being connected, e.g. by a bayonet joint. The shredded material is passed by a separate rotated helix 24 to the pressing screw 25 also In rotating connection with the mincer screw 3. The juice drains away from a casing 30. The residual pulp is forced through apertures 33 to an expelling screw 36 the inner flat end of which, or a separate disc, is held against the aperture 33 by a spring 39. An adjustable nut 40 controls the pressure of the spring 39 so that a controlled pressure is maintained on the pulp throughout the juice extracting chamber 26. The residual pulp passes through an outlet 29. Instead of the cylindrical shredding surface 5 a flat shredding plate may be used 43, Fig. 6 (not shown). The shredded material then passes through perforations in the plate, being scraped off the back by stripper bar 52 (not shown). Instead of shredding apparatus, cutting tools may be used to cut the fruit up fine enough to be pressed in the juice extractor. Such cutting tools may be like mincer cutters 59, 60, Fig. 7 (not shown).

Abstract: 1,142,062. Polymers comprising substituted polymethylene chains. GEVAERT-AGFA N.V. 18 April, 1967 [12 May, 1966], No. 21201/66. Heading C3R. Polymers consisting of units of formula where R is a substituted or unsubstituted aromatic or heterocyclic radical, are obtained by dissolving at least one tosylhydrazone of an aromatic or heterocyclic aldehyde in a heterogeneous mixture of a liquid containing a solvent for the polymer to be obtained and a liquid immiscible with the first liquid and preferably a solvent for the starting material, adding an alkali metal hydroxide to obtain a strongly coloured reaction mixture, refluxing with stirring until the colour disappears, and then precipitating the polymer in a non-solvent liquid. In examples, polymers are obtained from benzaltosylhydrazone, p-bromobenzaltosylhydrazone, oÀ, m- and p-methoxybenzaltosylhydrazones, α- and #-naphthaltosylhydrazones, 9-anthraltosylhydrazone and the tosylhydrazone of m-pyridine-aldehyde, and from mixtures of benzaltosylhydrazone with pbromobenzaltosylhydrazone, m-methoxybenzaltosylhydrazone and p-chlorobenzaltosylhydrazone; the reactions are carried out in mixtures of benzene, methanol and water.

Abstract: 1,041,745. Colour television. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 4, 1963 [June 1, 1962], No. 21222/62. Heading H4F. In a colour television receiver for use with a transmission comprising (1) a subcarrier wave bearing phase quadrature modulations in accordance with E R <SP>1</SP>/γ-E Y <SP>1</SP> and E B <SP>1</SP>/γ-E Y <SP>1</SP>, where E Y <SP>1</SP>=0 3 E R <SP>1</SP>/γ+0À59 E G <SP>1</SP>/γ+0À11 E B <SP>1</SP>/γ, and (2) a luminance signal of the form E Y <SP>1</SP>=(0À3 E R +0À59 E G +0À11 E B )<SP>1</SP>/γ, the individual colour signals (which are derived by matrixing to establish the " green " signal and then by subtraction of the luminance signal E Y <SP>1</SP>) are each in error by the factor + (E Y <SP>1</SP>/γ - E Y <SP>1</SP>). In accordance with the invention the error is reduced by subtracting from the luminance signal a signal which is linearly dependent upon the amplitude of the subcarrier wave. It is stated that in practice an acceptable degree of correction is obtained by subtracting a signal proportional to <SP>1</SP>/ 5 th of the amplitude of the subcarrier wave. In a first embodiment, Fig, 1, the luminance signal E Y <SP>1</SP>/γ is applied via delay line 13 and amplifier 15 to the commoned cathodes 2-4 of three-gun cathode-ray tube 1, whilst the colour-difference signals E R <SP>1</SP>/γ - E Y <SP>1</SP>, E G <SP>1</SP>/γ and E B <SP>1</SP>/γ - E Y <SP>1</SP> are applied individually to the grids 10-12. In carrying out the invention a resistor 14 is connected between the end of delay line 13 and the grid of amplifier 15 and has connected across it a rectifier circuit 18, 19, 20 which is supplied with the subcarrier wave. In a second embodiment, Fig. 2 (not shown), the subcarrier wave is applied via a voltage-doubler rectifier 21, 22, 24, 25 in series with the terminating impedance 16, 17 for the delay line. A circuit arrangement as described above may be arranged to be switched into a normal N.T.S.C.-type of receiver to permit reception with either type of transmission. Reference is made (without giving details) to the application of the invention to (1) receivers with a single-gun cathoderay tube, and (2) receivers for a modified form of N.T.S.C.-type of system using phase alternation techniques.

In an A.C. electromagnet, the yoke 11 is biased against a housing 15 by springs 13, 14 so as to prevent excess current due to the non- closure of the air gap between poles 18 and armature 17. During normal operation, the armature 16 is attracted towards the pole 18 so as to deflect member 19 which operates hydraulic apparatus. If the armature is prevented from moving into contact with pole 18, the yoke 11 will be deflected against the bias of springs 13, 14 so as to close the air gap and minimize the current in coil 12. Conical springs 13, 14 may be employed having a characteristic matching the force-gap characteristic of the magnet. In order to ensure that the full force is initially applied to the armature 16, the yoke 11 may be provided with an oil-filled damper or may have mass considerably greater than that of a conventional yoke.
