Title: Disc brake
IPC: F16D65/095
Filed: 1973-10-04
Abstract: 1394560 Spot-type disc brakes SOC ANON DBA 4 Oct 1973 [23 Oct 1972] 46430/73 Heading F2E A disc brake comprises a disc 12, a fixed support 28, 44, a caliper 14 straddling the disc, being axially slidable on the fixed support and incorporating applying means for a first pad 16, and a second pad 18 mounted on the caliper 14, wherein the fixed support includes a first column 42 extending parallel to the disc axis and situated on the line of tangential stress to which each pad is subjected during brake application, and a second column 20 parallel to the axis, the pads being mounted about the first column 42 and the caliper sliding on the second column 20, the first pad also co-operating with the second column 20 so as to permit it to slide axially between the columns. As shown, a caliper 14, Fig. 4, has lugs 22 by which it is mounted on a fixed column 20 for sliding movement parallel to the axis of the disc 12. An inner brake pad 16, engaged by an hydraulically-operated piston, not shown, is supported by its backing plate 30, 34, on an extension 46 of fixed column 20 and on another fixed column 42 also for sliding movement parallel to the disc axis. An outer brake pad 18 has two studs 52 each accommodated in one of two holes 54 in a caliper leg 50 and is resiliently secured to the leg 50 by a tongue 58 welded to the backing plate 32, 36, and engaging a spring wire 56 whose ends are resiliently accommodated in the holes 54; the pad 18 is also mounted for sliding movement by engagement of its backing plate with fixed column 42. The side of the caliper remote from lugs 22 is supported on the backing plate extensions 34, 36, by a noise-reducing spring 62 whose central portion 64 engages notches 66 in the extensions and whose ends 68 are anchored in the caliper. The extensions 34, 36, each have a flat edge 60 nearer the axis of column 42 than is the disc periphery, so that after tilting of the caliper and rotation of the pads in their own plane through approximately 180 degrees from the Fig. 4 position, they can be removed by sliding off column 42 without the need for disc removal.

Title: Improvements in steerable torque-balanced marine propulsion drive
IPC: B63H20/16
Filed: 1962-12-10
Abstract: 993,905. Differential gear. GENERAL ELECTRIC CO. Dec. 10, 1962 [Dec. 12, 1961], No. 46476/62. Heading F2D. [Also in Division B7] A torque-balanced drive for a steerable rotatably-mounted marine propulsion pod 2, comprises differential gearing means 12 driven, e.g. by a steam or gas turbine, said differential means having two output shafts 18, 17 rotating in the same direction; and means 24 for reversing the direction of rotation of one of said output shafts, the two oppositely turning shafts 18, 21 extending into pod 2 and being geared to drive output shaft 32. As shown, output gears 14 and 16 are of equal diameter so that coaxial shafts 18, 17 rotate at equal speeds and in the same direction. Also disposed coaxially about shaft 18 is another shaft 21. Shafts 17, 21 are coupled through gears 22, 23 and reversing idler level gear 24. Counter-rotating shafts 18, 21 are connected at their lower ends to bevel gears 29, 28 respectively which serve as pinions to drive propeller gear 30. The pod 2 is turned for steering by means of a pinion 8 meshing with gear rim 7. As gears 28, 29 are rotating at the same speed but in opposite directions the forces produced by the gears attempting to turn the pod 2 about its vertical axis, are cancelled out. In a modification (Fig. 3, not shown), an additional propeller output shaft is driven by gears 28, 29 and drives a propeller on the front of the pod. Since this propeller will rotate in an opposite direction to propeller 31 the pitches of the propellers must be in opposite directions.

Title: Thread controlling mechanisms in sewing machines
IPC: D05B47/00
Filed: 1970-10-01
Abstract: 1316460 Thread tensioning arrangements SINGER CO 1 Oct 1970 [7 Oct 1969] 46702/70 Heading D1G In a two-thread chain stitch sewing machine, tensioning devices 99, 109, Figs. 7 and 5, for the upper and lower threads respectively are arranged so that the respective take-up elements 23, 58, are positioned nearer to the thread-engaging surfaces of the tensioning devices than stationary thread guides 90, 131, guiding the threads to the devices. The upper thread take-up 23 comprises an eyelet in an arm reciprocating vertically with the needle arm and the tensioner comprises a flat plate 99 located by a peg 97 and held by a spring adjusted by a screw 98. When the thread is being pulled through the tensioner the takeup 23 is at the top end of its stroke so that the thread passes directly in the direction of its length through the tensioner whereby maximum resistance is obtained. At other parts of the cycle the thread is moved sideways down the tensioner plate, whereby the resistance is reduced.  The device 109 comprises a plate 116 urged against a plate 112 by a spring plate 120 pivoted on a peg 122 and secured by a screw 123, the plate 116 having a thread engaging edge 118 whilst its opposite edge 117 is recessed for free passage of the thread from a stationary guide 131. From the tensioner the thread passes to the take-up eye 58 of a loop taker 55 which moves bodily in an ovalshaped path, all points of which are closer to the thread engaging edge 118 than is the guide 131. The spring 120 applies to the thread engaging edge a pressure gradient which decreases from the outer end towards the centre. Whilst thread is drawn through the tensioner the loop taker 55 is near the point of maximum resistance; at other parts of the cycle the thread is drawn laterally along the thread engaging edge 118 whereby the resistance is reduced.

The machine may have a stator winding water cooled by the same supply as for the terminal. The fitting may be shrunk on to the lead 16, which has electrical insulation 18 and a central bore 17 through which is passed cooling gas or water. Seals 15, 22 render gas-tight the joints between the fitting, housing, and lead.

A fluid heater comprises tubular heatexchanger elements 1, 2, 3 concentrically disposed within a casing 4 to define annular chambers 5, 6, 7. Combustion gases from a burner 12 mounted on a plate 11 flow along a return path through the outer annular chamber 5 to leave through an exhaust 16. The medium to be heated enters through inlet openings 8 and 9 and flows along a return path through chambers 6 and 7 before leaving through outlet 15.

In a modification (Fig. 3, not shown) several outlet openings are provided at spaced locations along the length of the fluid heater between the burner and the inlet opening for the medium to be heated. Shut-off devices (26, 27, Fig. 4, not shown) may be provided in the annular chamber (7) at spaced locations to isolate sections of the heater. An inlet opening (28, 29) may be provided adjacent each shut-off device for introducing additional fluid(s) into the annular chamber (7). An additional heat exchanger element in the form of a flat disc (30, Fig. 4) may be provided at the end of the heater remote from the burner. The annular chambers 5, 6 or 7 can be filled with spheres of inert material (17, Fig. 5) such as steel or fire-clay to support the concentrically arranged heat exchanger elements.

Filed: 1976-11-18
Abstract: 1496859 Die quenching CATERPILLAR TRACTOR CO 18 Nov 1976 [3 March 1976] 48174/76 Heading C7N A method of die quenching a heated workpiece e.g. a crank-shaft, comprises holding the shaft between a pair of end supports under a light, (say 100 psi) i.e. non distorting pressure, moving two die blocks transversely towards the workpiece so that particular portions such as journals are contacted by the die blocks, and spraying a quenching liquid through passageways in the die blocks on to the particular portions of the shaft while simultaneously increasing the end pressure to e.g. 1000 psi pressure to prevent distortion of the workpiece. Further quenching of the whole crank-shaft is then applied by flooding the chamber formed by the die blocks about the crank-shaft with a quenching medium e.g. water. Selected further portions of the crank-shaft, e.g. the counterweights, which are not required to be so severely quenched as the journals, have gas annealing fixtures extending from the platens carrying the die blocks shaped to match the counterweights and slightly spaced therefrom, through which a gas under pressure, usually air, is supplied during the primary quenching and subsequent flooding quench. This pressurized air prevents these selected portions of the workpiece from being hardened as much as the remainder.
