Filed: 1949-03-31
Abstract: 665,646. Trench excavators. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 29, 1950. [March 31, 1949] No. 8830/49. Class 68 (i). A trenching machine comprises a wheeled chassis through a forward transverse girder of which slidably pass two transversely disposed tubular guides 10a, to the lower ends of which is secured a plate 11. Vertically slidable on the guides and controlled by a jack mounted on the chassis is a serrated cutting blade 30 whilst jacks 64 control a cutter 60. Behind the guides 10a, and 10b (not shown) and secured to a box structure 20 that is open on the leading side, are four jacks 40, 41, 50, 51 the piston rods of which are either connected to a yoke 52 connected with the guides or to the plate 11. This box supports jacks 24, 25 which are connected to pads 22 positioned at the sides of the box, the guide rods of said pads having a loose sliding fit in the said walls. In operation, a hole is dug and the guide rods, plate and boxlike structure lowered into it and jack is expanded until cutter 30 rests on plate 11. Then jacks 25 are expanded to force the pads against the walls of the hole thus fixing the box in the hole so as to absorb the reaction of the jacks 40, 41, 51 when they are expanded. The expansion of these jacks causes the tubes, carriage and horizontal cutter to move forward, the cutter penetrating the side of the wall. Cutter 60 is forced downwards so that a slab of soil is separated and this slab is raised upwards by the cutters and passes into a sleeve where it is retained whilst the next slab is removed by repeating the sequence of operations after the pads are released and the box structure advanced. As each slab is raised it forces the preceding slab out of the sleeve.

Abstract: 848,394. Hydraulic apparatus. MINNEAPOLIS-HONEYWELL REGULATOR CO. March 13, 1959 [March 18, 1958], No. 8842/59. Class 69(2). An hydraulic actuator comprises two variablevolume chambers 13, 14, containing an electrically-conductive fluid, a pump 10 for moving the fluid from one chamber to the other through a permanently open connecting passage 11, 12 against an external load, and an electrically operated control means 46 operable to urge the fluid in the opposite direction to the pump, the combined effort of the external load and control means serving to overcome the pumping effort when the control means is energized. The pump 10, which is of the electromagnetic type, has an inlet pipe 11 connected to the chamber 13 formed by a flexible bellows 17 in a cylindrical container 15, and an outlet pipe 12 connected to the chamber 14 similarly formed by a flexible bellows 24 in a cylindrical container 21. The bellows 24 is secured to a stem 32 connected to a load, such as a valve or other device, to be actuated, the load being urged to act in opposition to the pump. The pressure of the pump, however, is sufficient to overcome the external load and the liquid, which may be mercury or other liquid metal O1 a combination of sodium and potassium, is pumped through the permanently open passages 11, 12 to the chamber 14 to move the stem 32 downwardly. When the electromagnet 46 is energized, a core 52 secured to the bellows 17 moves upwardly to draw the liquid into the chamber 13 against the effort of the pump 10 and raise the stem 32. The electromagnet may be controlled from an amplifier or a manually controlled power source and a mechanical amplifying arrangement may be utilized.

Title: Method for breaking a rove during doffing in a flyer frame and a flyer frame for use in such a method
IPC: D01H9/04
Filed: 1976-03-05
Abstract: 1536495 Doffing arrangements TOYODA JIDOSHOKKI SEISAKUSHO KK 5 March 1976 [5 March 1975] 08873/76 Heading DID Rove is severed during doffing in a flyer frame by stopping the feeding of the rove from the forwarding rollers before the doffing, giving a predetermined additional twist to a portion of the rove between the rollers and the flyer top when the feeding of the parting a relative motion between the flyer rove from the rollers has stopped, and im- and the bobbin thereby to sever the rove at a portion adjacent to a presser attached to the flyer. As described, the additional twist is inserted into the rove after stopping the rollers by rotating the bobbin and the flyer at substantially the same speed. The rove may be severed by moving the wound bobbin downwardly, or by rotating either the bobbin or the flyer, or both of them, at different speeds. The drive arrangement for the flyer (Fig. 2 not shown) comprises a main drive shaft (15) which drives the flyer (5) via gears (16, 17, 20, 21). The forwarding rollers 4 are also driven from the main drive shaft (15) via gears (22, 23) clutch (25) and gears (26 to 29). The bobbin spindle (1) is driven by a train of gears (49 to 53) from one side of a differential gear 41. The differential gear 41, and thus the bobbin spindle 1, is rotated at a varying speed due to the rotation transmitted to the other side of the differential gear via shaft (31), variable belt drive (32 to 35) and gears (37 to 40). The differential gear arrangement is such that when the clutch (25) is disengaged and the rove forwarding rollers (4) are stopped, the rotation of the one side of the differential gear (41), i.e. gear (44), is stopped and the flyer (5) and the bobbin spindle (1) are driven at the same speed. The time during which the bobbin 1 and flyer 5 are driven at the same speed is controlled by timer 62, e.g. so that both rotate for about 5 revolutions. Following this, the bobbin rail 10 is lowered and the rove breaks at the relatively weak portion extending from the presser (5) to the bobbin. The bobbin may be lowered to a doffing position prior to the stopping of rotation of the bobbin and the flyer (5). The rove breaks between the presser (5) and the bobbin due to the rove being made stronger by the additional twist inserted into the rove following the cessation of the forwarding of the rove from rollers (4).
