Abstract: 628,262. Frame structures. MAXON, G. Aug. 19, 1946, No. 24653. [Class 20(ii)] [Also in Groups XV and XXVIII] A frame structure for scaffolding, trusses, toys and models &c. is assembled from lengths of helically deformed tubing 8-11, Fig. 2 connected by helically deformed fittings 12-16 which permit an entire length of the tubing to be screwed through the fittings. Fig. 2 shows the two end panels of a series of connected trusses forming a framework for a roof, the tubing and fittings being constructed in three correlated diameters, i.e. standard, oversize and undersize. The tubings 8-11 are of standard size while the fittings 12-16 are of oversize tubing and have branches perpendicular to the plane of the panels to enable a series of trusses to be connected together. The connections 18 for the lower ends of the diagonals 11 are made by means of interengaging nipples 20, 21 threaded into a branch of the fitting 13 and the diagonal 11 respectively, a coupling 22 being threaded over the connection. Fittings made in complementary sections may be used as a means for the attachment of bracing members to an assembled framework. The T-shaped fitting 30, Figs. 5, 6 for joining the end of the bracing member 31 to the side of a tube 32, is split upon the plane containing the axes of its branches to form complementary sections 34 which are applied to the exterior of the tubes without requiring threading of the tubes thereto. The stem portions of the fitting are secured together and to the tube 31 by a coupling 35 threaded over the stem portions. The complementary sections may be hinged along their adjacent edges remote from the stem portions and in a further modification hingedly connected complementary sections, not integral with the stem portions, are provided with trunnions 38, Fig. 8, and the stem portions 39 are pivotally connected with the trunnions 38 by arms 40 extending from the sides of the stem portions. Trunnions may be incorporated on any of the fittings for attachment of wire braces &c. and a coupling tube may be provided with trunnions for pivotally connecting braces &c. by means of split sections.

Filed: 1956-08-16
Abstract: Interpolymers are made containing 50-70% by weight of units of a monovinyl monocyclic aromatic hydrocarbon or of a mixture of such hydrocarbons, 25-40% by weight of units of an isopropenyl monocyclic aromatic hydrocarbon or of a mixture of such hydrocarbons and 10-15% by weight of units of one or more acids having the general formula CH2 = CR.COOH in which R is a hydrogen atom or a methyl or ethyl group.  Vinyl and isopropenyl aromatic monomers specified are styrene, vinyl toluene, vinylethylbenzene and 2,4-dimethylstyrene and isopropenylbenzene, isopropenyltoluene, isopropenylethylbenzene and 2,4 - dimethyl - isopropenylbenzene.  The interpolymers may be obtained by mass, solution or, preferably, emulsion polymerization techniques. Alternatively the aromatic hydrocarbons may be polymerized with a nitrile, ester or amide of the unsaturated acid and the resulting interpolymer hydrolysed to provide carboxyl groupings.  In the example styrene, isopropenylbenzene and methacrylic acid are interpolymerized by adding them together with a solution of potassium persulphate to a heated aqueous medium containing the sodium salt of an alkylaryl polyether sulphonate and an alkylaryl polyether.  The interpolymers may be used in the production of combs, toys, refrigerator panels and plastic pipe. Specifications 678,279 and 820,154 are referred to.

Abstract: 875,473. Control of motors. BRITISH INSULATED CALLENDER'S CABLES Ltd. Aug. 5, 1959 [Aug. 6, 1958], No. 25255/58. Class 38 (3). [Also in Group XXXVI] In a control system for a motor coupled to a drum, from or on to which a flexible material is wound, the tension in the flexible material is maintained substantially constant by regulating the torque applied to the drum in accordance with a potential proportional to the ratio between the angular speed of the drum and the linear speed of the material. As shown, a web 8, Fig. 4, is withdrawn from a drum 7 by a capstan 9 driven by a motor 10. The web is tensioned by a braking device coupled to the drum 7. The braking device comprises an alternating current motor as disclosed in Specification 875,472 or a device in which the relationship between the braking torque and a control potential is linear. The control potential is derived from a tacho-generator Gl, coupled to the capstan 9, having a field 4, Fig. 3, energized in parallel with a field 5 of a tachogenerator G2, coupled to the reel 7, by a magnetic amplifier A. The input coils to the amplifier A are energized from a direct reference voltage across lines 1, 2 and from the output of the tacho-generator G2. It is shown mathematically that the control potential is proportional to the ratio of the angular speeds of rotation of the drum and capstan and that the tension in the web is maintained substantially constant.

Title: Speech analysis system
IPC: G10L25/90
Filed: 1970-05-27
Abstract: 1,246,079. Speech analyser. INTERNATIONAL BUSINESS MACHINES CORP. 27 May, 1970 [2 June, 1969], No. 25406/70. Heading H4R. In a speech analyser rectified signals are derived representing the envelope of the speech components in respective frequency bands distributed across the speech spectrum. The rectified signals are summed and applied to a frequency discriminator to derive a voltage level proportional to the pitch frequency of speech during voiced sounds and a noise signal during unvoiced sounds. The level of high frequency components in the signal is used as a voicedunvoiced signal. As shown, Fig. 2, speech from microphone 1 is amplified and fed to a bank of filters 3 each having a bandwidth of about 300 Hz so as to pass two pitch harmonics. The filter outputs are rectified in 4 combined in a summing network 5 passed through a 70-250 Hz band pass filter 6 and modulated to about 15 KHz in balanced modulator 7. The upper sideband of the modulator output is selected in filter 8 and the signal limited and filtered to provide, at the output of filter 10, a constant amplitude signal of average frequency related to the pitch frequency of the speech, which is passed to frequency discriminator 11. The output of the discriminator is a signal whose level is proportional to the pitch frequency during voiced sounds and is noise during unvoiced sounds. The relatively slowly varying pitch signal is fed through LP filter 12 to output V1 while the noise signal is fed through HP filter 17 and rectified to provide a signal of one level, sufficient to operate threshold circuit 20 during unvoiced sounds, and a lower level signal, insufficient to operate 20, during voiced sounds.

Title: Improvements relating to ovens
IPC: A47J37/12
Filed: 1934-09-04
Abstract: 443,249. Service hatches. ROSS, C. E., and PERKS, T. E., (trading as ROSS & PERKS), 166, Piccadilly, London. Sept. 4, 1934, Nos. 25475/34, 8255/35, and 17536/35. [Class 20 (iii)] [See also Group XI] An oven, e.g. for keeping cooked food such as fish and chipped potatoes hot, comprises a heated cabinet with one or more drawers which are adapted to be slid in and out from either side of the cabinet, e.g. the kitchen side or the service side, heating being effected by hot gases flowing upwardly around or through the food containers. In one form, the drawer, shown in Fig. 2, runs on rails 4 in the cabinet 1, 2, 3, Fig. 4. A food container 9, with a perforated bottom 11, rests on the flange 8 on the drawer, which is provided with a drip tray 12. The rails 4, drawer and receptacle are displaced from the centre towards the side 3, so that hot gases entering the chamber from a duct 13 pass either around the tray 9 or, it may be, through the bottom 11, to the outlets 15. The cabinet and end members 5, 6 of the drawer may be lagged. A number of cabinets may be associated in a single structure. In the form shown in Fig. 5, two tiers of drawers 16, 17, 18 and 29, 30 are mounted in a cabinet above tiers of drip trays 20, 21, 22 and 31, 32, 33 respectively. Hot gases from the burner box 23 pass over the top trays 20, 31 and rise through the perforated bottoms of the drawers to the ports 24 at the bottoms of the recess 25, which act as plate racks. Rods 34 are attached to the tray 20 on one side of the cabinet and to the tray 21 on the other side of the cabinet, and extend upwardly in front of the drawers 16, 17, 18 so that when a drawer is drawn out in either direction one or other of the trays 20, 21 is also drawn out. A similar arrangement applies to the drawers 29, 30 and their associated trays. To prevent its complete withdrawal, each drawer has associated with it two pairs of pins which project downwardly from two bars in the cabinet, one near each side. The pins are staggered, and the ends of the drawers are slotted as at 27 so that either end of the drawer can pass one pair of pins and abut against the other pair. To allow complete withdrawal of the drawer when required, one end may have slots corresponding to both pairs of pins, one pair of slots being normally closed by a slotted slide 28. Either of the drawers 29, 30 may be locked from one side of the cabinet so that it cannot be opened at the other side, by a rod which passes through the cabinet and with a handle at one end and a catch at the other. An oven made as previously described may be associated upon a common suction box base with one or more cooking devices made as described in Specification 443,785, [Group XI], the heating gases from the oven and the hot gases and fumes from the cooking devices being thus drawn downwardly into the suction box. Alternatively, the fumes from the cooking devices may be drawn through the oven, and then into the suction box. In this modification the oven has an opening in the top with a cover fitted with hinging means serving also as fastening means.
