Patent GB-102514-A (GB)
Title: Improvements in Rotary Mechanisms for the Transmission of Power at Varying Speeds.
Inventor: HUNT WILFRED
IPC: F16H33/10
Filed: 1916-01-07
Abstract: 102,514. Hunt, W. Jan. 7, 1916. Variable-speed gearing.-Relates to gears of the type described in Specification 21414/12 in which the gear varies automatically with the load. In the present application, the oscillating inertia members are so connected to both driving and driven members that their phases of acceleration and retardation are approximately equal. The driving or driven shaft 12 carries a swash-plate 18 carrying on ball bearings a gimbal ring 23, which has pivots 24 engaging blocks 13 secured by bolts to two fly-wheels 11 arranged one on each side of the shaft and having pivots 15 engaging a driven or driving casing 16. Unless the parts 12, 16 rotate at the same speed, the swash-plate 18 produces oscillation of the fly-wheels 11, the amount of oscillation varying with the difference in speed of the primary parts, and this difference depending on the load. Cams or Z-cranks may replace the swash-plates. In a modified form, the fly-wheels are dispensed with, the gimbal ring 23 being heavily weighted and pivoted in a second ring replacing the fly-wheels and pivoted on the casing 16 at the points 15. When used for driving purposes, three such devices are arranged in a single casing with the swash-plates arranged at an angle of 60 or 120 degrees to each other; or, in the form in which the fly-wheels are used, the swashplates may be arranged parallel, and the fly-wheels be arranged at the required angles. In the Provisional Specification, references are made to the use of cross-slide or straight-line-motion devices for connecting the inertia members to the primary parts, and to the arrangement of the inertia members so that their axes are parallel to the main axis or so that they reciprocate in an axial or radial direction.

Title: Improvements in or relating to textile bobbin orienting and loading apparatus
Inventor: PRAY L
IPC: D01H9/18
Filed: 1970-01-05
Abstract: 1286041 Supplying bobbins to machines MAREMONT CORP 5 Jan 1970 [11 Feb 1969] 388/70 Heading D1F Tapered bobbins 10 are removed from a hopper 6, oriented so that they pass through a chute 25 large end first, and loaded onto a conveyor 50. A pivoted carrier 30 (Fig. 5), moved by cylinder 38 allows one bobbin at a time to fall from hopper 6 onto a plate 20, through a hole 32. The carrier 30 is pivoted, pushing the bobbin past tapered fingers 22, one of which engages the large end, and moves the bobbin axially towards the smaller. At the end of this movement, the bobbin drops into a funnel-shaped portion of chute 25, its small end hitting an abutment 24 so that the large end travels down the chute first, to a second carrier 40. This carrier has an open side 41, is pivoted about a vertical rod 46, and is also moved by cylinder 38 when a notch 54 in a motor-driven conveyor belt 50 (Fig. 3) allows air to flow from a pipe 66 to a pipe 68. The carrier 40 is thus moved in synchronism with projections 52 on the belt 50, so that the bobbin is transferred thereto. Air flow between pipes 65 and 67, as the conveyor progresses, returns the two carriers 30, 40 to the Fig. 1 position.

Title: Improvements in and relating to electrical indicating circuits
Inventor: STEPHENS ROBERT CHARLES
IPC: G01F1/36
Filed: 1955-01-06
Abstract: 793,106. Electric tests. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 4, 1956 [Jan. 6, 1955; June 3, 1955], Nos. 401/55 and 15941/55, Class 37. [Also in Group XXXVIII] The indicating or recording member of a self-balancing bridge or potentiometer moves in accordance with the square root of the variations in resistance or voltage caused by a primary variable which may be, for example, the pressure difference between the two sides of an obstruction in a pipe in which a liquid flows. This is effected by balancing the bridge or potentiometer by means of a slide wire shunted by a fixed resistor which is of equal value where the range covered by the indicator is to extend to zero. Bridge device, Fig. 1.-The ratio arms 2, 3 are preferably equal and 1 is the unknown resistor. The bridge is automatically balanced by a mechanical coupling between the galvanometer movement and a slide wire 4 constituting with a shunting resistor 5 the fourth arm. The slide wire contactor C is moved automatically in accordance with the square root of variations in 1. Potentiometer device, Fig. 3. A movable core 1 connected to a bellows manometer responding to the difference in pressure across a restriction in a pipe acts differentially on secondaries 3, 4 of a transformer. The rectified outputs of these secondaries act differentially on a galvanometer 10 mechanically coupled to the slider of a slide wire 5 shunted by a fixed resistor 6 in such a way that the potentiometer is self-balancing. An adjustable resistor 7 for calibrating and a protective resistor 11 for preventing damage to the rectifiers are provided. The network comprising capacitors 12, 14 and inductor 13 which may be omitted improve the response at low inputs. Since the manometer responds in accordance with the square of the rate of flow, the indicating device shows rate of flow on a linear scale. Modifications.-Zero suppression, i.e. exclusion from the range of the instrument of reading below a desired positive value, may be achieved by giving resistor 5 (Fig. 1) a resistance greater than that of the slide wire. Range multiplication may be obtained by connecting a pair of ganged variable resistors of equal value, one in parallel with each of coils 3 and 4, or one in series with each coil.
