Title: Travelling wave shedding looms
IPC: F23Q7/00
Filed: 1970-12-15
Abstract: 1336440 Travelling wave shed looms A LINKA 15 Dec 1970 [17 Dec 1969] 59586/70 Heading D1E A travelling wave shedding mechanism comprises healds 6 at the ends of longitudinally slidable rods 3 whose other ends have butts 15 sliding in moving guide tracks 12, 13 which have branching sections 14, 38 with diverters 21 at the junction points of the branches, controlled to guide the butts 15 selectively into a selected branch of the track, to produce different weaves. The guide tracks are formed on members 9a, 9b which are curved, Fig. 3, and rotated about a vertical axis when the mechanism is used on a circular loom (Fig. 1, not shown), or which are straight and hinged together with a plurality of such members and driven in an endless chain, when the mechanism is used on a conventional straight loom Fig. 7. Three sets of guide tracks I, II and III are provided corresponding to three different lengths of rods 3. The rods 3 are arranged one above another in radial grooves 2 in a fixed bed 1 as described in Specification 1300464. The diverters 21 are arranged on rotatable shafts (24), Fig. 6 (not shown) projecting through the members 9a, 9b and having arms (25) acted upon by an element (27) on a fixed part of the loom to move the arm (25) and hence the diverter one way or the other as it passes by. The elements (27) are operated by solenoids connected to a pattern reading mechanism, through a controller (C) Fig. 5, not shown). A thread breakage detector may be connected to the controller so that, upon breakage of a thread being detected, all of the butts are diverted into a branch 38 of the guide track, so that all of the warps are held outside of the path of the shuttle and no shed is formed.

Title: Photographic cameras
IPC: G03B9/07
Filed: 1971-12-22
Abstract: 1331700 Photographic cameras POLAROID CORP 22 Dec 1971 [24 Dec 1970 21 July 1971] 59705/71 Heading G2A A camera 2 is switched between a configuration in which the shutter speed is varied automatically in response to illumination, and one in which the aperture is coupled to a distance setting when a flash-gun portion 16, which is normally folded against the camera body 4, is rotated to the working position shown. A rotatable knob 104 controls a variable-density filter 126, and trims the illumination reaching a photo-sensitive element 136 to compensate for subject variation. The variable filter knob 104 and element 136 are disabled when the flash-gun portion 16 is in its working position, and a link 90 actuates a variable aperture in the portion 16 instead. Preferably flash illumination is provided by a flash-cube 10 mounted on the body 12, and the shutter is electronically timed.

Title: Rotor blades for rotorcraft
IPC: B64C27/467
Filed: 1973-12-28
Abstract: 1450965 Aerofoils BOEING CO 28 Dec 1973 60013/73 Heading B7W An aerofoil, particularly for a helicopter rotor blade, has a profile developed from a NACA 6 series to provide a point of minimum pressure, at or about the design lift coefficient located less than 30% of the chord length behind the leading edge. As shown in the Figure the chord line c and the mean chord line m pass through the leading and trailing edges, the line m being determined by the equi-distant depths d along the chord. The maximum thickness t is expressed as a percentage of the chord and the aerofoil is defined by cartesian coordinates wherein the x axis is coincident with the chord line and the leading edge is the origin, and upper and lower offsets y. When tabulating the profile x and y are divided by the chord length to give x/c and y/c and the description includes tables setting out such co-ordinates for preferred aerofoil profiles. These were obtained by extrapolating from NACA sections having their point of minimum pressure located respectively at 30% and 40% chord to produce aerofoils denoted VR-7 and VR-8 having a t<SP>max</SP> at 12% and 8% chord.

Patent GB-646327-A (GB)
Abstract: 646,327. Cables. PIRELLI-GENERAL CABLE WORKS, Ltd., and ARMAN, A. N. Oct. 22, 1948, No. 27485. [Class 36] An oil-filled electric cable of the type having two or more insulated cores 1 lying side by side, has an outer sheath 3 comprising one or more metal strips, the edges 6 of which are welded together along a line lying on or near the major axis of the sheath, and having outwardly extending ribs 7 formed in the plane sides of the sheath. The sheath may consist of two trough-like elements, the longitudinal edges of which are welded together, or may be made from a single strip of metal bent around the cores with its longitudinal edges welded. In either case the longitudinal edges may be turned outwardly to form flanges which are then welded. The ribs 7, which may be located transversely or obliquely to the length of the cable, allow for variations in the volume of the oil within the cable as well as giving the cable longitudinal flexibility and transverse stiffness. Specification 617,577 is referred to.

IPC: D01H5/26
Abstract: 709,004. Textile drafting apparatus: SCHIESS AKT.-GES. Oct. 5, 1950 [Oct. 29, 1949]. No. 24293/50. Class 120(2) A drafting field is divided into sections by supports carrying aligned shaft sections over which drafting aprons pass and each apron, which serves at least two spindles, is so mounted that it may be removed from operative position along with its associated shaft section. In one preferred form, Fig. 5, the aprons 1 extend from one support 4 to another and are supported by plates 5, shaft sections 3 and guide rollers 6. A positive drive for the aprons may be provided, such as by forming teeth on their inner surfaces and on the shaft sections 3.

Title: Fuel/Air Ratio Control of an Internal Combustion Engine using a Fuel Containing Partially Oxygenated Hydrocarbon
IPC: F02D41/14
Filed: 1979-01-15
Abstract: The fuel/air ratio of a mixture of air and a fuel containing petrol and a substantial portion of partially oxygenated hydrocarbons, for example ethanol or methanol, is maintained at or close to stoichiometric by a closed loop control. The control includes an oxygen sensor 14 in the exhaust from the combustion chamber 10 which provides a state signal E1 indicating whether burning is below or above stoichiometric. The state signal is processed by an air-to-fuel ratio control circuit 22 to provide a control signal E2 that biases an air-to-fuel ratio control mechanism 20 in a direction that maintains the air-to-fuel ratio within a very narrow band around stoichiometric. A three-way catalyst is employed to minimize the pollution output from this internal combustion system and because of the closed loop control, the catalyst's effectiveness is optimized. <IMAGE>
