Title: A method of and system of double locks for knitting fabrics of varying width on a flat knitting machine
IPC: D04B7/04
Filed: 1963-02-13
Abstract: 1,008,006. Knitting-machines. H. STOLL; G. STOLL; E. STOLL; Dr E. STOLL; J. STOLL; A. STOLL; R. E. STOLL and M. STOLL. Feb. 13, 1963 [Feb. 13, 1962], No. 5802/63. Heading D1C. A flat two-bed knitting machine having double locks comprises means for transferring stitches from at least one of the marginal needles of first one bed and then the opposed bed to an adjacent needle and means for guiding these needles after transfer to a non knitting path at each stroke of the carriage in either direction. As the cam carriage moves from right to left (Fig. 2) needle butts N pass between lead in cams 1 and 2 and are raised by a needle advancing cam 6. At this point transfer means (not shown) push at least one marginal needle N<SP>1</SP> along a path shown by a dotted line A to effect a transfer of loops, the emptied needle then travels along a channel 18 and is acted on by a swinging picker finger 32 and follows a non-knitting path B between cams 21 and 22. In the front bed marginal needles N<SP>1</SP> from which loops have been removed follow paths A<SP>1</SP> and B<SP>1</SP> as described above. The remaining active needles are operated by cams 6, 8 and 11 or 7, 9 and 13 to produce a fresh course of stitches, no knitting having taken place at the leading knitting section of the double locks. Similarly when the locks move from left to right (Fig. 3) the marginal needles have their loops transferred when moving along the path C or C<SP>1</SP> and are taken out of action along the path B or B<SP>1</SP>. To produce a 1 x 1 or 2 x 2 rib the shaded cams 25 and 33 in the front lock are moved to a "half way in" position to operate on long butted needles Nh, cam 25 moving these needles to a position where they transfer their loops to the needles of the rear bed and cam 33 retracting them, after transfer, to a non-knitting position.

Title: Improvements in or relating to swashplate liquid pumps
IPC: F04B1/20
Filed: 1955-03-02
Abstract: 765,279. Reciprocating pumps. BOSCH GES., R. March 2, 1955 [March 3, 1954], No. 6145/55. Class 102(1) In a multi-cylinder liquid pump having a rotatable cylinder block 8, 9 with several cylinder bores 12 containing pistons 14, a driving shaft 6 fixed to said block and a disc 27 surrounding the shaft and inclined thereto, the inclination of the disc determining the length of stroke of the pistons, one side 8 of the cylinder block is attached to one end of the shaft and the opposite side 9 is rotatably mounted on a fixed bearing stud 4 coaxial with the shaft, a chamber 22 being provided in the block adjacent the inner end of the bearing stud and adapted to be subjected to the full feed pressure of the pump whereby the thrust on the block produced by liquid pressure in the cylinder bores and tending to displace it in one direction is at least approximately compensated for by the thrust produced by the feed pressure existing in said 'chamber and tending to displace it in the opposite direction, namely away from the bearing stud. The cylinder bores have annular grooves 18 and 19, the groove 18 of each cylinder being connected by a passage 20 with the inner end of another cylinder bore which is off-set by 90 degrees round the cylinder pitch circle, while the groove 19 is connected by a passage 21 to the chamber 22. The pistons have longitudinal grooves 15 so dimensioned that they connect the groove 18 alternately with the interior of the housing 1 and with the groove 19 during movement of the piston 14, thereby controlling the inlet and outlet of liquid relative to the cylinder bore. The inclination of the disc 27 is adjusted by rotating it about an axis which lies in the plane 42 containing the outer ends of the pistons. A lever 39 attached to the disc is urged by a spring 40 to incline the disc as obliquely as possible. The pump obtains liquid from a reservoir 48, throttle valve 47 and inlet pipe 46, and delivers it to a pipe 50 leading to a hydraulic engine 51, from which it is exhausted back into the reservoir. When the pump output is to be reduced, the valve 47 is closed slightly. An increased partial vacuum is thereby produced in the cylinder bores which are taking in liquid so that the total pressure exerted on the swashplate 25 by the pistons at the bottom, is greater than that exerted by those at the top and the swashplate moves to a less inclined position until the tension in the spring 40 offsets this out of balance force, the change in inclination of the swashplate reducing the stroke of the pistons.and hence the pump output.

Abstract: 709,195. Oil-break switches. BRITISH THOMSON-HOUSTON CO., Ltd., and COX, H. E. June 13, 1951 [March 14, 1950], No. 6393/50. Class 38(5) A high voltage oil-break circuit-breaker having contacts which may be opened to provide arc interruption and an isolating gap is provided with an additional circuit interrupting unit having contacts which have a separation only sufficient for arc interrupting purposes. The circuit-breaker comprises an insulating bushing 11 filled with oil and containing an arc-extinguishing chamber 12 in which an axially-moving contact rod 13 co-operates with a fixed contact 14. The rod 13 is moved by actuating mechanism 16 through a distance sufficient for the unit to withstand the maximum circuit voltage. The additional unit has an insulating oil filled cylinder 22 only large enough to contain an arc-extinguishing structure 20, and its moving contact rod 21 moves only a sufficient distance to provide in conjunction with the circuit-breaker unit, an effective arc-extinguishing action. Thus the two units are able to interrupt a high voltage circuit necessitating two series breaks, the circuitbreaker unit then providing effective isolation. The additional unit is mounted on the casing 15 housing the mechanism 16 which is extended as indicated at 16A so as to operate the additional unit. The casing 15 is mounted on a supporting insulator 17 which may house a current transformer 18 and a shunt resistor 27, 28 may be provided for each unit.

Member 2 is a screw-device for delivering powder to the developing mechanism and is biased to the left by spring 8. A motor 12 drives member 2 via gears 10, 11, 12, 13 and may also drive a parallel agitating roller (3). When the tanks is full, the displacing force is sufficient to compress spring 8, and a micro-switch M5 is engaged. When the tank has emptied to a predetermined level, the displacing force is sufficiently low for the member 2 to move sufficiently to the left under the action of spring 8 for the micro-switch to be disengaged to cause motor 12 to be switched off or a lamp to be switched on or off. Alternatively, the gears 12, 13 may have widths such that when member 12 moves sufficiently to the left, the gears disengage, a lever 18 being provided for restarting drive to roller 12 when the tank has been refilled.

Title: Improvements in or relating to aircraft landing gear
IPC: B64C25/52
Filed: 1953-03-10
Abstract: 726,573. Aircraft landing gear. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-EST. March 10, 1953 [March 20, 1952], No. 6621/53. Class 4. [Also in Group XXXII] A main landing gear for an aircraft 1 comprises a pair of symmetrical retractable frame structures 3, 3a, Fig. 2, disposed symmetrically relative to the longitudinal axis of the aircraft and provided with friction beams or skids adapted to act as landing skis, these frame structures being hinged about parallel longitudinal axis for retraction and extension by a control device adapted to lock them in either position, said frame structures being associated with resilient means (see Group XXXII) providing the damping of ground unevennesses and a torsional damping about their hinge axles in the extended position, said frame structures themselves constituting in their retracted position the external fairing closing the aircraft fuselage. As seen in Fig. 5, the skid comprises a lower beam 5 having a skid surface 6 and pivotally mounted at 11 to an upper beam 4 rotatably mounted in the aircraft. Ties 16, 17 and 16a, 17a, are provided and two shock absorbers composed of rubber discs 21 and metal plates 22 are used to damp out ground unevenness (see Group XXXII). The upper beam 4 is fast to the splined shaft 35 engaging discs bonded to annular rubber members 44 which are sheared when rotation of beam 4 occurs in the extended position. Referring to Figs. 9 and 13, extension from the retracted position of Fig. 9 is by jack 66 having two diametrically opposed stops 72 adapted to engage the double levers 74 and 75, of which the former has a notch receiving a pin 72 on a flange 78 of beam 5, keeping the skid retracted. On extension of jack 66, the skid does not move until pin 68 on the skid is engaged by the inner end of slot 67, during which movement stop 72 has deflected cam surface 81 on lever 74, unhooking the skid. Extension then takes place, and on completion, the shock absorber of the longitudinal axis automatically locks itself in position so that the skid may resiliently rock in a plane transverse of the aircraft, pin 68 having play in slot 67. Stop 72 follows the dashed path 102. On retraction, the lost motion of the jack due to slot 67 enables stop 72 to deflect lever 75 which rocks a bell crank 88 unlocking the shock absorber, enabling the skid to rotate freely back to the position in Fig. 9, pin 77 automatically re-engaging in the. notch of lever 74. A micro switch 79 is operated by pin 77 on engagement, and may give a visual or aural signal to the pilot. The space opened by the extended skis may be used for dropping personnel, bombs, or the like.
