Abstract: 995,516. Resilient mountings. AEROFLEX LABORATORIES Inc. Oct. 30, 1963 [Dec. 3, 1962], No. 42850/63. Heading F2S. In a universal vibration isolator a continuous length of stranded wire cable 20 is looped between, and secured by tabs 21 to, disc elements 12, 13 the upper disc 13 being fixed to the base of an inverted cup-shaped member 14 which carries a support stud 11 and extends through an aperture 16a in a second inverted cup-shaped member 16 secured by bolts 18 to the lower disc 12 and a supporting platform 10, and a resilient snubbing element 19 being encased around the aperture 16. In alternative arrangements the continuous length of cable 20 is replaced by two interleaved sinusoidal closed loops of cable or, by a plurality of substantially circular loops formed by separate lengths, or by a continuous length, of cable. Fig. 5 shows a cable which is reeved through openings in the discs 12, 13 so as to extend normally from the opposed faces of the latter, the stiffness of the isolator being increased by a surrounding coiled tension spring 27 or by a solid ring of resilient material.

Abstract: 978,015. Tumbler driers. GENERAL STEEL WARES Ltd. Dec. 13, 1960, No. 42911/60. Heading F4G. A tumbler drier comprises a perforated drum 4, Fig. 6, within a housing 20 having an inlet 21 to which air, heated by direct contact with a gas burner 36, is supplied along a folded air path 32a.. . 32d formed by a generally triangular shaped housing 29 mounted on the housing 20 and an inner baffle 30. A steam of indirectly heated air is also supplied to the inlet 21 by passage between a thin heat transfer surface 33 mounted above the burner and the outer wall 31 of the housing 29, and a further indirectly heated air stream by-passes the folded air path by passage through a duct 35 formed by a housing 34 overlying the housing 29 and enters the drum 4 through the inlet 21 but at another side of an imperforate strip 24 which divides a perforated screen covering the inlet 21 from that in which the folded air streams enter the inlet. A fan 10, Fig. 2, draws the heated air through the inlet and drum and out of housing outlets through a lint filter for discharge at an exhaust 28. A flame pattern detector 54 comprising a temperature responsive device is mounted through openings in the housings 34, 29 immediately above the heat transfer surface 33 and downstream of the burner 36 to control by a solenoid-operated valve the gas flow to the burner upon abnormal temperature when the pattern of the flame 59 alters to the dotted position shown at 60. Gas is supplied to the burner through a manually controlled cock 43 and is delivered through solenoid controlled valves 44, gas line 46 to a pilot burner and through a main gas line 45 to the burner 36. The operation of the drier is also controlled by a timer to regulate the length of operation of the drier, an adjustable thermostat to select the temperature at which the drier is to operate and a temperature-responsive element 53 to shut-off the heat energy source via the valves 44 in response to abnormal temperatures in the drum. The drum is horizontally mounted on a shaft 3 within a casing 48 and rotated by a motor 8 through a reduction drive comprising belts 11, 16 and pulleys 12, 15, 17, the motor also driving the fan 10 through the belt 11.

Abstract: 918,489. Regulating. DAIMLER-BENZ A.G. Dec. 15, 1960 [Dec. 16, 1959], No. 43224/60. Class 7(6) [Also in Group XXVI] A governor 12, Fig. 1 controlling a fuel injection pump control rod 11, is overridden when the accelerator pedal 31 is depressed beyond a point of perceptible increase in resistance. As applied to a suction governor the accelerator pedal 31 is connected to the throttle valve 28 through a resilient lost motion device 29 and the governor suction chamber 13 is connected to the induction pipe through a port 33 controlled by a cock 32 actuated from the accelerator pedal by a lost motion link 40. In the full load position shown, the spring 29 is uncompressed and the cock 32 connects chamber 13 to the induction pipe. On further depression of the pedal 31, valve 28 remains stationary and spring 29 is overcome, providing an increase of resistance. Rod 40 turns cock 32 to open an orifice 35 to atmosphere to increase the pressure in chamber 13 so that the governor is set for operation at a higher speed. In addition the increase in pressure in chamber 13 enables a spring 23 between the maximum delivery stop 25 and the diaphragm to be overcome to produce an increased fuel supply. In a modification, Fig. 3, depression of the pedal 31 against spring 29 operates a lever 46 to contact a projection 47 on the rod 11 to render the governor 13 inoperative. A resilient link 50 may permit the governor to override the lever 46 at higher speeds.

Abstract: 1,240,357. Weft stop motions, shuttleless looms. SULZER BROS. Ltd. 13 Sept., 1968 [26 Sept., 1967], No. 43701/68. Heading DIE. A stop motion for a gripper shuttle loom with weft mixing or with weft selection allowing one weft, or more than one weft to be picked simultaneously, has means at the picking side of the loom to ensure that only the picked weft or wefts are sensed. A rocker 40 cooperates with a number of spring loaded blocking members 32 each attached to a weft guide 30 and each acted on by a comb 54 operated in conjunction with the weft selection mechanism. The stop motion may operate at any point in the weaving cycle and the comb, when moved by the selection mechanism allows, in the absence or lack of tension in the weft, the selected blocking member(s) to pivot to prevent the rotation of the rocker 40 to stop the loom. A pivoted weft feeler is also provided at the weft exit selvedge.

Abstract: 893,890. Securing end-windings of dynamoelectric machines. GENERAL ELECTRIC CO. Dec. 29, 1959 [Dec. 29, 1958], No. 44100/59. Class 35. A turbo-alternator rotor retaining ring 3 is secured against axial movement by a locking ring 9 having inwardly-directed lugs 12, 13 which are entered along the tops of the winding slots and then abut against surfaces 1h, 1J on the rotor teeth when the locking ring is rotated, thus producing a bayonet-type lock. The locking ring is segmented or else cut through at 11 to enable it to be assembled in a groove 3a in the retaining ring which is then heated so that it may be shrunk on to turned-down surface 1c of the rotor. The retaining ring and locking ring are slid axially on to the end of the rotor and the locking ring is then rotated into a locking position by means of the lugs 13 which project axially of the end 3d of the retaining ring for this purpose. A screw 21, engaging slots 13a, 14a secures the locking ring against rotation. Lugs 12 may, if desired, be of the same size as lugs 13. In a modified method the locking ring is a tight fit in the groove and is rotated by turning the whole retaining ring before cooling. In this case lugs 13 need not project axially. The pole-face carries damping conductors 7 secured by amortisseur wedges 19, the field winding slots being closed by wedges 18. A centering ring (not shown) is shrunk in the outer end of the retaining ring.

Upper chains 112 secure the upper portion of the wall to a conical frame via resilient brackets 113. In the transport position the chain 112 supports the wall from the internal hooked part of bracket 113. The tines can be mounted in bracket 127 to be upwardly pivotable about axis 133 (Figure 16) and are resiliently mounted about axis 143. Adjustment of the tines about axis 143 is either by an inwardly extending bend 146 of the tine rod engaging one or the other side of lever 142 or by a pin and slot arrangement. A further arrangement (Figure 22) has a support 162 for tines 164 mounted so that the tines hang outside the wall 34. The support can be moved about pivot 163 into an internal inoperative position. An adjustable offset weight 188 (Figure 28) can be associated with each tine group 36 to counteract, when under centrifugal force, the rearward movement of the tines when working. The flexible wall can be stiffened by vertical members. The rake head is supported by a wheel, shoe or skid and crop guides to the rear of the machine can be incorporated. Additional tines extending inwardly of the wall can be provided (Figure 19 not shown) and in a further embodiment (Figure 25 not shown). The wall is supported from an upper ring by strip elements of plastics or leaf spring material. The wall can be stiffened in the embodiment of Figure 27 (not shown) by spring steel rods fixed to spoke supports and extending downwardly and rearwardly along the wall surface.
