Abstract: A thread delivery apparatus for textile machines comprises a pair of nested wheels inclined one relative to the other for accepting multiple turns of yarn. Instead of the axes of the wheels passing each other with a finite minimum spacing as with nested godet wheel frames, the axes (18, 19) are in a common plane and intersect at a point (20) outside the thread control zone in the plane of a centering disc (23.1) fast on one of the wheels. The drive is transmitted from one wheel to the other through the centering disc.

In the traverse motion of the type including a scroll cam with an endless cam groove consisting of at least one pair of right- and left-hand grooves joined at each end and a strand guide which has a cam follower fitted in the endless cam groove of the scroll cam and is adapted to reciprocate along a straight path in parallel with the axis of the shaft of the scroll cam when the latter is rotated, the lead angle of the endless cam groove is increased adjacent to its ends or adjacent to each returning point of the cam follower so that the guide is increased in velocity adjacent to each returning point.

Abstract: An acceleration sensor for a seat belt retractor of the type having an operating member, for example a pawl, engageable with a locking mechanism, for example a toothed wheel, the sensor comprising a pivoted driver situated below the pawl, and having a center of gravity located above its pivot so that it will tend to topple, a lifting surface on the driver positioned radially outwardly from the pivotal axis, and a yoke having its lower end engaging the lifting surface and constrained thereby, its upper end engaging the pawl and constrained thereby, arranged so that tilting of the driver about the pivotal axis lifts a portion of the lifting surface and in turn lifts the yoke, whereby the pawl is lifted to its wheel engaging position.

Abstract: A muffler of the Helmholtz resonator type has a housing surrounding a main gas flow conduit, the gas flow conduit having an apertured zone within the housing wherein apertures extend through the conduit wall, the shape of the conduit wall at the apertured zone being so varied that gas flows through the apertures into or out of the housing, the flow inhibiting the development of whistle noises.

Abstract: A surface drainage system comprising base members (27) and cover members (32). The base members have a channel formed between opposite walls thereof, and are designed to be laid end-to-end with the channels in longitudinal alignment. The cover members are of inverted channel section and have opposite side walls with a channel defined therebetween. The cover members are laid above the base members and combine therewith to form an enclosed drainage channel. Each cover member has at least one opening (37) extending through a side wall thereof and communicating with the channel. The lowermost part of the opening intersects the outer surface of the respective wall at a location (36) that is no closer to the bottom than to the top of the cover member. A carriageway (35) can be laid with its surface no lower than the point (36), so that drainage is effected through the opening (37) while the base members (27) lie at a significant depth below the carriageway surface.

The piston is formed with a hydraulic cylinder chamber having fitted therein a hydraulic fixed piston of the hydraulic cylinder member so that the piston can move freely in a cylinder body. An oil chamber defined by the end of the hydraulic fixed piston and the end of the hydraulic cylinder chamber is communicated with an oil tank via an oil passage mounting a check valve that can be opened by pressing means including a pilot piston and other parts.

Abstract: The invention provides a method of apparatus for refinishing a vehicle brake disc. The brake disc is rotated while in place on the vehicle and is brought into contact with one or more abrading discs, which are rotated as well, thereby grinding the brake disc. The abrading discs are maintained in contact with the brake disc by being mounted on a holder which is secured into a portion of the vehicle which is fixed with respect to the brake disc. The preferred arrangement is to attach the holder to the brake caliper mounting associated with the brake disc to be ground. In a preferred embodiment two abrading discs are used, and they can be adjusted to be slightly out of parallel with one another, so as to grind the brake disc with more pressure in a desired region than in another region.

Abstract: Apparatus and method for marking a rotating tire, for example, to indicate the point of maximum radial force variation. The apparatus includes a marker head which is pivotable into contact with an inking pad in a direction similar to the direction of rotation of the tire at the point of contact of the marker head with the tire and which is also retractable from the tire.

Abstract: An electrical information transmitting means for consumer load control comprises a transmitter which transmits a coded signal through the conductors of an alternating current electrical distribution network as a sequence of wave-form distortions to a receiver which decodes the signal. The receiver comprises two correlators connected in quadrature, and the transmitters and each correlator synthesize synchronous signals from the power frequency, all of which is locked thereto. The D.C. voltage outputs of the correlators are squared and summed so that the receiver is independent of phase angle.

Abstract: A metal plate stands on a cross tie above an opening in the tie and a rail clip has a substantially straight leg which is driven into the opening, bears upwardly and is at most 2 mm. below a flat bottom of the plate. Second and third parts of the clip bear downwardly on the upper face of the rail flange and the upper face of the plate, respectively. This assembly may be made from an existing assembly in which a spike had its head overlying the rail flange and holding the rail down, the making of the new assembly including the step of forming the opening in the tie without moving the plate.

Abstract: To hold a railway rail down on a support member, a device is employed having a first part driven into a vertical hole in the support member, a second part having a sideways projection, part of which lies vertically below a part of the support member, to one side of the bottom of the hole, and further parts forming an arch above the support member. A convex portion of the first part co-operates with the wall of the hole during the driving operation to form a pivot about which said device rocks to cause the above-mentioned part of the projection to come under the above-mentioned part of the support member. A portion of a clip is driven under the arch and presses upwardly on it, another portion of the clip bears downwardly on the flange of the rail and a third portion bears downwardly on a fixed surface which, as seen from the rail, is beyond said first portion.
