Title: Power transmission belt and method of making same
IPC: F16G5/20
Filed: 1972-02-07
Abstract: 1358142 Moulding V-belts DAYCO CORP 7 Feb 1972 [1 March 1971] 5649/72 Heading B5A [Also in Division F2] An endless V-belt 20 comprises a loadcarrying section 24 and a compression section 26 having sides 30 provided with recesses 34. The latter may extend wholly or partly (Figs. 4, 5) across the sides 30 and may be rectangular or trapezoidal (Figs. 3, 6) in shape. The section 24 may comprise a spirally wound cord 23 which may be partially enbedded in a tension section 22. Recesses (71D, 77E, 75E, Figs. 6, 9) interconnecting the side recesses 34 may be provided in the top and/or bottom of the belt. A rubber impregnated fabric cover 21 may be provided. The belt 20 may be formed by placing the section 24 in an annular mould cavity 54 defined by upper, intermediate and lower mould parts 41, 42, 40 and injecting elastomeric material into the cavity 54 via a sprue 60, passages 62, 65, annular runner 55 and annular slit 46 to form the compression section 26.

Title: Improvements in power transmission mechanism
IPC: F16H61/02
Filed: 1933-02-24
Abstract: 409,484. Variable-speed gearing. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. Feb. 24, 1933, No. 5681. Convention date, March 30, 1932. [Class 80 (ii).] A transmission mechanism including a clutch operated by centrifugal members for connecting driving and driven shafts in one speed ratio has means for connecting the shafts in another speed ratio comprising mechanism adapted to contact the centrifugal members and move them into inoperative position. As shown, gearing, connecting a driving shaft 10 with a driven shaft 19, includes a loose sleeve 49 which is splined to a friction clutch housing 33, to a sleeve 68 coarsely threaded to the hub 56 of an over-running clutch, and to a coupler 53. A countershaft 84 has a gear 88 engaging a pinion 13 on shaft 10, a gear 89 engaging teeth 52 on the outer member of the over-running clutch, and a gear 91. The over-running clutch includes rollers 57-60, Fig. 5, acted upon by a spring-urged block 62 located in a tapered groove 63 by a member 64 fixed to the hub 56. The sleeve 68 carries a ring 71 abutting centrifugal weights 43 pivoted to the clutch housing 33 and is subjected to a compression spring 70. A spring 74 on the hub 56 is held compressed by a stop 77. The frictionclutch plates have a backing plate 36 supported by springs 37, and light springs 46 tend to move the weights 43 outwardly. The clutch plates 29 splined to the shaft 10 have radial slots extending inwardly from the outer periphery beyond the central hole in the clutch plates 32 fixed to the housing 33, and the latter has openings in its periphery to permit the squeezing out of oil from between the clutch plates as the clutch is put into engagement. A slidable gear 21 is splined to the driven shaft 19. In operation, for a forward drive, the gear 21 is slid so that teeth 82 thereon engage teeth 81 on the coupler 53. A direct drive takes place through the members 33, 49, 53, 21, to the driven shaft 19, the roller clutch over-running. If the friction clutch slips, a drive at reduced speed takes place through the members 13, 88, 89, 52, 57, 56, 68, 49, 53, 21, 19. The hub 56 due to its threaded engagement with the sleeve 68 moves the latter to the left so that the ring 71 moves the weights 43 inwardly and the friction clutch is disengaged although the housing 33 is still rotated by the sleeve 49. Upon increase of speed the weights 43 move outwardly to force the sleeve 68 to the right and engage the friction clutch so that a direct drive again occurs, the roller clutch over-running. At a certain speed the ring 71 abuts the compression spring 74, and further outward movement of the weights 43 is prevented until a predetermined further increase in speed occurs. If the gear 21 is moved to engage the teeth 82 with teeth 83 on the gear 52 the engine may act as a brake while the transmission is in second gear. Engagement of the gear 21 with a loose pinion 92 gearing with the gear 91 gives a reverse drive.

Abstract: 1511081 Parabolic dish TRW Inc 16 Feb 1976 [28 Feb 1975] 06012/76 Heading H4A A paraboloidal dish, e.g. for an antenna reflector, is made by forming a planar array of curved strips 32 which fan away from each other and are each of uniform width, then bending the strips to bring their adjacent edges together so that the strips conform to a paraboloidal surface, the projection of those edges onto a plane perpendicular to the principal axis of said surface then being an array of parallel straight lines. In the embodiment described each strip has a set of spaced linear conductors on its surface, formed on a thin glass fibre substrate by photo-etching. The strips are joined at their roots as shown. The edges of the bent-up strips may be joined so that the dish becomes self-supporting, or the dish may be used as a liner in a moulded graphite/epoxy dish to which it is bonded.

A crystalline sintered element is produced by mixing a powdered silica-containing glass with an inorganic salt capable of promoting crystallisation of the glass and heating to sinter and devitrify the mass. A suitable glass contains: SiO 2 , 54%; B 2 O 3 , 3%; Al 2 O 3 , 27%; divalent metal oxide, 16%. This is finely ground and mixed with one of the following, also finely ground-lithium carbonate, aluminate or silicate, magnesium carbonate or silicate, aluminium nitrate-together with an organic binder such as paraffin wax dissolved in carbon tetrachloride. The mass is pressed into shape and then heated, first to evaporate the solvent and then to decompose the binder. The latter may be accelerated by the addition of decomposable oxidising agent such as ammonium nitrate. Successively higher temperatures then sinter the mass and devitrify it.

The pressure of a gas is measured by a face balance arrangement comprising a hermetically sealed sphere 70 Fig. 1 located in the test gas atmosphere, carried by a beam 11 whose displacement fan the horizontal is sensed at 14 and automatically removed by a proportional current through a movable coil 12 attached to the beam 11, co-operating with a permanent magnet 13a. It is shown that the voltage drop across a resistor 22 in the coil circuit is proportional to the gas pressure. If the temperature coefficient of resistance of resistor 22 is made equal to the pressure coefficient of the gas at constant volume (usually 1/273), the p.d. across resistor 22 is proportional to the gas pressure independent of the temperature. The fulcrum of the balance comprises a stainless steel cradle 15 supported by torsion tapes 16 stretched horizontally between vertical springs 17. Movement is limited by plates 20 and rods 21.

[Class 38 (v)] A mercury type switch consists of a closed vessel containing a pool of mercury, upon which floats a hollow vessel also containing a pool or pools of mercury into each of which dips an electrode, the mercury in the two vessels being normally out of contact, a ring-like armature within the closed vessel and surrounding the hollow one being capable of movement under the influence of a magnet outside the closed vessel, so as to tilt the hollow vessel, and cause the mercury in the pools to merge making contact between electrodes. In Figs. 1 and 2 the partition c divides the hollow vessel c into two parts, the two pools merging through an aperture f in the partition, when the vessel is tilted, by movement of the armature i, the opposite end of the vessel being prevented from being depressed by means of prongs k.
