Title: Vibratory bar feeder for machine tools
IPC: B65G27/34
Filed: 1974-11-15
Abstract: 1443118 Vibratory conveyers LIPE ROLLWAY CORP 15 Nov 1974 [16 Nov 1973] 49508/74 Heading B8A [Also in Division B3] A vibratory bar feeder for feeding bars axially to a bar working machine tool, e.g. thread rollers, screw machines, cutting-off machines and centreless grinders, comprises a magazine 20 for storing bars 25; a mechanism for dropping bars one at a time from the magazine; a trough 13 below the magazine for receiving a dropped bar, the trough extending beyond the magazine towards the said machine tool and the inside of the trough being covered with a pile material having flexible filaments uniformly inclined by 5-25 degrees from a vertical transverse plane toward the said bar working machine tool, the said filaments having uniform length and a sufficient density so that only the tips of said filaments support said bars; and means for vibrating the trough in a reciprocal motion so that the filaments flex under the bars during upward movement of the trough and translate the vibratory motion into a feed for moving the bars axially. The filaments may also be inclined transversely to impact rotary motion to the bars. The trough is mounted by spring connectors (19) (Fig. 1, not shown) and rubber mounts 18 to a pair of vibrators 17. The mechanism for dropping the bars from the magazine comprises an air cylinder 29 which rotates a shaft 31 carrying brackets 32. Pins 35 passing through guide blocks 36 engage the brackets 32 so that on rotation of the shaft-31 the pins 35 are raised to lift one bar over a stop 27. A guide plate 28 ensures only one bar is lifted over the stop 27. The magazine has end guides 21, 22, 23, one of which is adjustable at one end of the bed 11 of the feeder for accommodating bars of different lengths. Control switches (37), 38 sense the leading and trailing end of a bar in the trough and actuate the cylinder 29 accordingly.

Title: Stability means for a controller for fluid pressure operated de vices
IPC: B62D5/09
Filed: 1973-10-24
Abstract: 1444019 Power-assisted steering mechanism EATON CORP 24 Oct 1973 [24 Oct 1972] 49602/73 Heading B7H In a hydrostatic steering controller comprising a valve sleeve 12 having apertures 20 which co-operate with slots 18 in a valve spool 10 when the spool is in a neutral position with respect to the sleeve to provide a fluid flow path between an inlet port 72 and an outlet port 73, augmentation orifices 16 are provided in the sleeve 10 adjacent the apertures 20 to stabilise pressure changes when the spool and sleeve are relatively roted from the neutral to an actuated position. The apertures 20 in the sleeve 12 include charging apertures 128, two rows of circular apertures 132, and two rows of gain holes 136 axially aligned with the apertures 132. The slots 18 in the spool 10 include charging slots 18 which are aligned with the neutral position with the charging apertures 128, and stability slots 133 having a width at one end 135 equal to the diameter of the circular apertures 132 and at the other end 137 equal to the diameter of the gain holes 136. The augmentation orifices 16 are the same size as the gain holes 136 and are positioned one on each side of each gain hole by such a distance that they cooperate with the stability slots 133 as the spool and sleeve are displaced from the neutral position to modify the closing rate of the fluid flow path. Circumferential grooves 122, 124 and discontinuous axial grooves 131 are formed in the spool 10 as described in Specification 48048/75 to balance pressures acting around the spool and maintain the spool centrally disposed within the sleeve 12. The spool 10 has splines at one end 97 for connection to a steering wheel shaft, and the sleeve 12 is connected by a drive pin 102 and wobble shaft 57 to a geroter pump/motor unit B. The drive pin 102 is received by slots 103 in the spool 10 with sufficient clearance to allow limited relative rotation which is resisted by leaf springs 106. Slots 112, 114, 116 and 118 in the spool 10 and apertures 113, 117, 119 in the sleeve 12 cooperate upon relative rotation of spool and sleeve from the neutral position so that fluid from the inlet port 72 is directed to one of steering motor ports 74, 75 by way of the pump/ motor unit B and fluid is returned from the other motor port 74, 75 to the outlet port 73.

Abstract: 1332580 Zig-zag chainstitch sewing machines VIRGINIO RIMOLDI & C SPA 27 Oct 1971 [13 Nov 1970] 49922/71 Heading DIG In a zig-zag two thread chainstitch sewing machine, a spreader member 45, movable in the direction of arrows C and D (Fig. 2), holds back the needle thread loop 79 (Figs. 4, 7) to facilitate entry of the needle into the triangle formed by the looper 21, the looper thread 77 and the needle thread loop 79. The drive to the spreader 45 which is fixed to a shaft 60, is from the main drive shaft 4 via a cam 71 and members 72 73, 74 and 75 (for axial movement in direction D) and via a cam 70 and members 42 and 43 (for rotational movement in direction C). The drive to the looper 21, which is fixed to shaft 37, is via a cam 48 and members 49, 50, 51 and 52 to a sliding engagement between the fork 54 and block 55, and thence via levers 57 and 58 for rotational movement in direction B). Axial movement A comes via a cam 30 and pitman 31 (Fig. 1) and levers 32, 33 and 34. The needle drive from an upper shaft 12 is via a crank 25 and connecting rod 26. The zig-zag movement between needle positions I and II is obtained from shaft 12 via gears 14 and 14a, and a cam 15 embraced by a forked lever 16. The fork is firmly attached to a lever 18, and both pivot about an axis 17, so causing a longitudinal movement in link 19 and hence shaft 91. The width of the zig-zag is variable by moving the end of link 19 along the slot in the lever 18.

Abstract: 1370435 Holography PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 27 Oct 1971 [30 Oct 1970] 49955/71 Heading G2J Images of different parts of an object lying at different depths are reproduced by sequentially illuminating a plurality of tomographic holograms 7 arranged along a curve corresponding to that described by the illuminating source during formation of the holograms. Preferably the holograms are sequentially illuminated by light from a rotating mirror 3, the normal to which is at an angle to the mirror shaft 4. Thus the illuminating beam describes a cone whose apex is the centre of rotation of the mirror. The reconstructed images are viewed through diffusing screen 9. In an alternative embodiment the illuminating beam is incident on the rotating mirror 3 through an aperture in a further mirror 13 from which the beam is reflected to the holograms after reflection from mirror 3. The diffuser plate 9 is measurably movable to enable sharp images of particular details to be viewed. The images may be reconstructed in superposition faster or slower than the resolution of the eye. The screen 9 may be replaced by a film cassette or the images may be projected on to a television camera.
