Title: Skip-Stitch Mechanism for Household Sewing Machines.
IPC: D05B81/00
Filed: 1968-09-30
Abstract: 1,177,469. Sewing machines. SINGER CO. 30 Sept., 1968 [6 Oct., 1967], No. 46355/68. Heading D1G. A sewing machine comprises an arm shaft, a driving member coupled to the arm shaft, a rotary driven member operatively connected to the needle bar for imparting endwise reciprocation thereto, means for coupling and uncoupling the driving and driven members under the control of programme means, and means for rendering the programme means inoperative. Needle bar 20 is mounted in a pivoted gate 22 oscillated, for producing zig zag stitching, via a pitman 70 as described in Specification 891317 from a pattern cam 38 fast with a rotary shaft 28 driven via gearing 34, 36 from the arm shaft 16. The latter is journalled at the machine head 14 in a sleeve 92 which in turn is journalled in a fixed bearing 94. Sleeve 92 is connected by a crank 24 and pitman 26 to needle bar 20 for imparting endwise reciprocation thereto. A spool-shaped driving member 112, slidably but non-rotatably mounted on shaft 16, is adapted to be moved axially on shaft 16 for being coupled to and uncoupled from sleeve 92. A compression spring 104, mounted within sleeve 92, biases the latter against a circlip 100 on shaft 16, and biases member 112 against a lower arm 180 rigid with a vertical pivoted pin 176 to engage an upper follower arm 182 with a skip-stitch control cam 188 rigid with rotary shaft 28. The arrangement is such that when arm 182 engages a lobe on cam 188, member 112 is shifted leftwards for drivingly engaging a lug 170 thereon with a lug 130 on sleeve 92, and member 112 also co-acts with a pin 160 carried by a member 132, pivoted on a pin 140, to turn member 132 clockwise against the bias of a spring 154 to disengage a lug 150, carried by member 132, from a recess (128) formed in sleeve 92. When arm 182 engages a trough in cam 188, member 112 moves rightwards to uncouple from sleeve 92, while lug 150 moves over a helical surface 124 on sleeve 92 before reentering recess (128) to hold needle bar 20 in the raised position. A pin 202, carried by arm 182, passes through a slot 196 at one end of a bar 194, the other end of which is pivoted at 208 to one end of an arm 206 pivoted at its other end on a fixed pin 210. A spring handle 214, rigid with arm 206, passes through a slot in the machine frame and is selectively engageable with notches A, B, C formed therein. When the middle notch B is engaged, pin 202 moves freely in slot 196 and the needle bar drive is controlled by cam 188. When the left hand notch A is engaged, the right hand end of slot 196 co-acts with pin 202 for coupling member 112 with sleeve 92. When the right hand notch C is engaged, a bar 216, connecting bar 206 with a bearing 218 journalling a bobbin-winding spindle 222, shifts bearing 218 rightwards for drivingly engaging a wheel 220 on spindle 222 with the main driving pulley 19.

Abstract: 1,272,653. Power steering. BENDIBERICA S.A. 22 Sept., 1969, No. 46602/69. Heading B7H. A servo-steering mechanism comprises a shaft 15, a surrounding sleeve 20 having ports therein, and an internally toothed spindle 8 into which the shaft extends, the shaft having therein at least one longitudinal groove 25, (41) with sides which can engage with a tooth 16 of the spindle and which groove acts to selectively establish communication between the ports in dependence upon the relative radial positions of the shaft and sleeve. The shaft includes a torsion bar 17 connected by the pin 18 to shaft 8 which co-operates via re-circulating balls 9 with a slide 7 having teeth 6 meshing with those 5 of a toothed sector 4 connected to a steering bar. In its neutral position, shaft 15 interconnects inlet and outlet ports 27, 28 respectively. However, during steering movement of shaft 15 in one direction fluid entering port 27 finds a way, via the ports in the sleeve 20, and groove 25, to tube 30 and hence enters chamber 14 to move the slide 7. Rotation of shaft 15 in the other direction causes slide 7 to move in reverse manner.

Abstract: 1,167,041. Ice making. FLUGEL & CO. (LONDON) Ltd., and D. C. PARR. 20 Oct., 1966, No. 46931/66. Heading F4H. Water is frozen in recesses 6 in the upper surface of a block 3 through which a freezing medium is circulated, the ice being ejected by rotation of a motor-driven spindle 21 provided with radial arms 20. The arms are angularly staggered to contact the ice blocks successively and thereby reduce the loading on the spindle, and, as illustrated, are arranged in two groups A and B separated by 180 degrees so that a half rotation of the spindle will eject ice from half of the recesses 6. The width of the recesses increases in the direction of ejection and also increases upwardly so that the freezing of the water tends to lift the ice blocks. Ice ejection is initiated by push button or coin freed mechanism, a system of cams and microswitches, Fig. 9 (not shown), being arranged to rotate the spindle through an angle sufficient to eject one group of ice blocks and then to refill the recesses of that group with water by operation of a solenoid valve 48.

Abstract: 984,144. Aerials. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Dec. 21, 9621 [Dec. 22, 1961], No. 48282/62. Heading H4A. A Luneberg lens 1 having an outer reflective surface 8 is known to reverse the direction of polarization of a circularly polarized wave impinging thereon and since raindrops and clouds produce a similar effect it is also known to suppress such "reversed echoes " in radar apparatus, thus rendering a Luneberg lens ineffective as a target. According to the invention this " reversal " is prevented by means of an additional reflector disposed within the lens, this reflector comprising a plurality of parallel wires spaced apart by a   distance of less than #/2 and dis-   posed parallel to the reflective surface 8 of the lens 1 and at a distance therefrom of n#/8 or n#/4 where n is any   odd integer. Thus in the case where the distance is n#/8 (and preferably where n=1) an incident circularly polarized wave is reflected as a linearly polarized wave and in the case of n# 4 (and preferably where n=1) the directions of rotation of the incident and reflected circularly polarized waves are the same.

Abstract: 1,074,690. Hydraulic turbines; centrifugal pumps. ESCHER WYSS A.G. Dec. 23, 1963 [Jan. 18, 1963], No. 50723/63. Headings F1C and F1T. The runner 1 of a hydraulic pump or pumpturbine connected to a synchronous electrical machine 4 is run up to speed for its pumping function by a starting turbine 9. At starting the water level in the suction tube 6 is lowered to a point 8 and water from the inlet 11 of the starting turbine 9 is sprayed through nozzles 19 into the runner chamber 15 to exert a braking torque on the runner 1 and prevent overspeeding of the set. An adjustable throttle valve 20 controls the water flowing to the nozzles 19 and a non-return valve 21 prevents flowback through line 18 when the runner 1 has reached operating speed and the turbine 9 has been shut-off. Additional braking torque is obtained by water fed to the runner chamber 15 through throttle and non-return valves 25, 26 respectively. In a modification, the braking water is not taken from the starting turbine inlet 11 but is supplied from a separate pressurized source. In this case a shut-off valve in the braking water line is connected to operate simultaneously with the starting turbine shut-off valves 13, 14. In a further modification, Fig. 2 (not shown) the starting turbine runner (27) has a centrifugal pump impeller (28) integral therewith. The impeller (28) communicates with the turbine draft tube (30) through a passage (31) in the runner hub having a non-return valve (32) which opens at a speed above the working speed of the machine being started but below the runaway speed. Thus water is pumped back from the draft tube (30) to the turbine inlet (29) to exert a braking torque on the runner.
