Title: An improved skip
IPC: E02F3/34
Filed: 1947-05-05
Abstract: 633,009. Skips. REID, J. M. May 5, 1947, No. 12076. [Class 78 (iv)] A skip mounted in bearings on a framework which may be detachably carried on a tractor or other vehicle has locking means to retain the skip in an upright load carrying position and is so mounted that in the absence of the locking means the skip would remain upright when unloaded and would become inverted when loaded. As shown a skip comprises a bowl 1 mounted in bearings 2 on a framework 3, 4 detachably secured to the body 5 of a tractor, the bowl 1 being open at the top so that it may turn in the bearings 1 to dump the material carried. The framework 3, 4 is triangulated and rests upon body members 6 of the tractor to which it is secured by pins 7. A spring-loaded lever 12 pivoted on the framework carriage lever 11 having a notch 13 adapted to engage a catch 14 on the bowl 1 to hold it in the load carrying position. A gate 19 through which material can be discharged from the bowl 1 is controlled by a lever 20, pivoted on the bowl 1, through a linkage 22, 24, which interferes with the locking device 12, 11, 13 so that the bowl cannot be inverted when the gate 19 is open and vice versa. Means may be provided for locking the bowl 1 in its inverted position, a wheel or wheels supported on a strut or struts connected to the framework and resting on the ground, may be provided as additional support for the weight of the framework, and the links 24 may be shaped to follow the curvature of the bowl 1. The bowl is formed as a segment of a circle so that no part of it interferes with the discharge of the contents either through the gate 19 or from the open top.

Title: Liquid-displacement measuring apparatus
Inventor: THOMPSON BERNARD
IPC: G01F1/37
Filed: 1956-04-20
Abstract: 824,304. Measuring liquid level. T.I. (GROUP SERVICES) Ltd. April 1, 1957 [April 20, 1956], No. 12092/56. Class 40(1). [Also in Group XIX] An apparatus for measuring liquid displacement comprises two interconnected vertical tubes one of which has an electrical device for detecting movement of liquid away from a particular level and the other of which contains a piston driven by a servo motor actuated by signals from the device in the first tube to restore the level in the first tube. In Fig. 1 a metal gas bottle d is to be tested under pressure and its movement displaces liquid in the container c. The piston e prevents movement in the larger tube a so that liquid rises in the tube b and generates a signal in the device j. The servomotor f is thereby actuated and rotates the nut h on the threaded rod i to raise the piston e until the original level is restored in the tube b. The device j as shown is a capacitance whose dielectric is varied by the change in level but it may be a pair of contacts bridged by the (conducting) liquid (Fig. 3, not shown) or a pair of lamps and photo-cells (Fig. 4, not shown). Fig. 2 shows the application of the invention to the measuring of fluid flow in the pipe n. The pressure difference across the orifice o causes the liquid level in the right-hand limb of the U-tube p to change, this being restored by movement of the piston e as before. In both applications the change in the initial variable quantity is measured in terms of the displacement of the piston.

Title: Coupling for ski-binding cables
IPC: A63C9/083
Filed: 1964-03-23
Abstract: 1,057,644. Ski bindings. L. BERCHTOLD and A. SCHUSTER. March 23, 1964 [March 22, 1963; Feb. 6, 1964], No. 12157/64. Heading A6D. A ski binding device comprises two coupling members 1, 2 releasably connecting the ends of binding cables 3, 10, the members having hook portions 8, 14 and a co-operating projection 5 and recess 6. In a forward fall the members 1, 2 will pivot with respect to the projection and recess before parting. When a skier falls laterally stop surfaces 13, 15 will act as a pivot point before the members disengage. In a second embodiment (Fig. 5) a hook portion 21 is pivotable relative to the member 2, and the ends of the cables are attached to washers normally spring urged to the upper ends of the members 1, 2. The portion 21 is normally held fixed with respect to the member 2 by a counterstop 27 which engages stop 25. When a skier falls forwardly the counterstop which is connected to the washer associated with cable 3 moves downwardly and is disengaged from stop 25 thus permitting pivotal movement of the portion 21 prior to disengagement of the members. In a further embodiment similar to that of Fig. 5, the cables are tensioned by springs at their ends adjacent a front tightener, and the counterstop is connected to the tightener by an inextensible cord. Longitudinal movement of the members moves the counterstop out of engagement with the stop on the hook portion.

Title: Improvements in and relating to buttonhole sewing machines
IPC: D05B3/08
Filed: 1933-05-02
Abstract: 400,114. Buttonhole - sewing machines. HUGHES, R. M., 72, Cannon Street, London.-(International Button Hole Sewing Machine Co. ; 502, Harrison Avenue, Boston, U.S.A.) May 2, 1933, No. 12785. [Class 112.] The required length of under-thread to form the first stitch of the next buttonhole is drawn through the throat plate before severing. The thread passes through a tensioning device 17, over a lever 27, through guides 19, 77 and thence through the throat plate 11. The required length of thread is first drawn through the tension device by the lever 27 and is then pulled through the throat plate by a hooked arm 51. The lever 27 is operated when the stitch frame is moved from the stitching to the cutting position by an arm 38 which is mounted on a pivoted block 39. A fixed pin 43 riding over a cam surface 45 tilts the block 39 and rocks over the lever 27. At the same time the thread tension device is released by a cam surface 30 engaging a pin 32. During the sewing operation the arm 51 occupies the full line position shown in Fig. 6. During the operation of the arm 27 the arm 51 moves over the under-thread and clamps it in the throat plate slot 46, but leaves the stay cord free. On the turret rotating, the arm 51 moves to the dotted position and the arm 27 swings back to its original position, thus enabling the thread to be pulled through the throat plate and subsequently severed. In a modification, the thread is pulled through the throat plate as the turret is rotating by an extension 62, Fig. 9.
