Title: Improvement in Apparel Corsets.
Inventor: KOPS DANIEL
IPC: A41C1/00
Filed: 1918-02-27
Abstract: 115,794. Kops, D. Feb. 27, 1918. Corsets.-In closed-back and laced-front corsets, such as are described in Specification 113,748, and in which lacing-devices are arranged for exerting an inward and upward pressure on the abdomen, adjustable self-reducing straps are combined with hose-supporter straps in such a way as to exert a circumferential pressure and thus produce a flattening effect on the abdomen. The lacing 17, Fig. 2, is arranged in all respects similar to that described in Specification 115,793, but the self-reducing strap 20, having eyelets 22 adjustably engaging a hook 23 on the steel 11 similar to that described in the latter Specification, has an extension 24 forming the hose-supporting strap. This strap passes through a slot 25 in the skirt 19 of the corset, and in front of an insert 20<1> which is attached to the body of the garment by lines of stitching 21<1>, 21, 22<1> and also to the edge of the reinforcing-strip 15. In a modification, the self-reducing strap is connected by lacing to an anchor strip stitched to the body of the corset forward of the hip section, so that it can be adjusted both by means of the lace and by the hook and eyelets. This double adjustability of the self-reducing strap also occurs in the modification shown in Fig. 4; but in this example the hose-supporter strap 57 does not form a part of the self-reducing strap, but is connected to the body of the garment by lines of stitching 54, 49. In this arrangement also, an adjusting-strap 61 is attached to the upper edge of the skirt section on one side, and has eyelets 62 which can engage adjustably a hook on the front steel of the opposite half of the corset front. In the modification shown in Fig. 6, the self-reducing strap 64 is permanently connected to the front steel section and adjustably connected by lacing 71 with the anchor-piece 68, while the side hose-supporter strap 75 extends over the self-reducing strap 64 and under the skirt section. In each form of the invention, a skirt insert, as above described, is used, and aLso a tongue, acting as a gauge, behind the lacing 17, as described in Specification 114,965. Further, the lacing at 17 may be adopted on both sides of the front steels.

Patent GB-998300-A (GB)
Title: A machine tool for the machining of gearwheels with uninterrupted feed of variable speed
IPC: B23F23/12
Filed: 1964-01-29
Abstract: 998,300. Gear-finishing. F. HURTH, and H. HURTH. Jan. 29, 1964 [March 13, 1963], No. 3757/64. Heading B3K. A gear-finishing machine comprises separately adjustable means for feeding the work or tool, for allowing a dwell, and for a slight disengagement before a complete withdrawal. In operation, a spring 38 adjusted by a screw 39 feeds the workpiece upwardly at a fast rate as allowed by the rotation of a cam 27. At a predetermined position, a switch is operated by cams 34, 35 to alter the speed of the transmission 30 to rotate the cam 27 slowly. At a further position, the cams 34, 35 again operate the transmission to cause a very slow feed or a dwell, followed by a slight withdrawal, accompanied by a further change of speed. The workpiece is finally withdrawn. In a modification, a feed screw 102, Figs. 5 and 6, is rotated through an hydraulic, electric or mechanical reversing clutch 115, and is urged upwardly by a spring plate 128a. A control drum 122 controls a motor 125 for setting a variable-speed drive 106, the lengths of the dogs on the drum determining the alteration in speed. When the up-feed is terminated by blocks 71, 71a, continued rotation of the screw 102 causes the screw to be moved down against the spring 128a. Thereby, a switch 129 is actuated and the clutch 116 is disengaged. After a time delay, the clutch 116 is engaged in reverse at a slow separation speed. A fast downfeed is terminated when a switch 129a is actuated by the feed-nut 103. The spring 128a may be omitted and a slipping clutch 111 introduced into the drive. In a modification, the feed is produced hydraulically.

Patent GB-142066-A (GB)
Title: Improvements relating to flanged pipes
IPC: F16L23/024
Filed: 1918-11-22
Abstract: 142,066. Rushes, E. J. Nov. 22, 1918. Flanging. - In a process of flanging pipes of ductile iron such as Bessemer or open-hearth steel or wrought iron, the end of the pipe is heated, and then supported externally near its end, and rolled under pressure exerted in a direction substan. tially parallel to the axis of the pipe until the flange contacts with an abutment. Flanges with parallel faces are thus produced, and sections can be bolted together without the use of reinforcing collars. The end of the pipe 1 is first heated sufficiently to produce appreciable outward deformation thereof, and is then secured near the end in clamps 15 so as to allow unrestricted radial flow, and acted on by a roller 11 freely rotatable in bearings 14 on a head rotating on an axis coincident with that of the pipe. Inwardly and out wardly extending portions 12, 13, Fig. 3, are first produced, which by continual action are converted to the form shown in Fig. 4. Further action displaces the metal outwardly until it reaches the face of the jaws 15, where it is finally rolled, Fig. 6, to a thickness substantially equal to that of the pipe. Inward displacement of the metal produces a square corner during the last stage. The taper on the periphery of the flange may be removed by machining. The width of the flange can be regulated by the amount of projection of the pipe through the jaws 15. If desired, the flange may be rolled to a greater thickness than the wall of the pipe and then reduced by machining. Either the work or roller head may be fed axially, fluid, pressure being preferably used.

Title: Improvements in machines for planing metal sheets
IPC: B23Q11/08
Filed: 1940-02-29
Abstract: 540,410. Machinery guards. MASSE, T. J. Feb. 29, 1940, No. 3824. Convention date, March 30, 1939. [Class 80 (iv)] [Also in Groups XXII and XXIII] A machine for planing metal sheets comprises a movable table carrying the work and a substantially vertical rotary spindle which is resiliently supported and carries a diamond tool which is moved transversely across the work surface. The general arrangement of the machine is similar to that described in Specification 492,813, [Group XXII]. A down folding shutter 100 prevents the work from being pushed against the rotating tools carried by a high speed tool head 34. The shutter is connected through lever mechanism to a bolt 107 coacting with a spring-urged bolt 109 controlled by bellows 111 connected to the vacuum in the table. When a workpiece is removed and the vacuum destroyed the bolt 109 is lowered so that it engages bolt 107 and the table is locked. After positioning a fresh sheet the shutter is raised withdrawing the lower bolt while the vacuum in the work holder withdraws the upper bolt thus freeing the table.
Patent GB-938882-A (GB)
Title: A safety latching device for motor vehicle doors
IPC: E05B65/12
Filed: 1960-02-03
Abstract: 938,882. Latch fastenings. L. R. LEMAINE A.G. Feb. 3, 1960 [Jan. 25, 1960], No. 3840/60. Class 44. In a latching device for motor vehicle doors either the bolt member or the keeper member is arranged to be further displaceable in the fastening direction away from its normal fastened position adopted on slamming the door, the bolt member and keeper member being so interconnected that the further displaceable member is further displaced in the fastening direction if the door is pulled away from the door jamb in the general plane of the door, the interconnection and further displacement of said member being effected by permanent magnet means disposed adjacent one of the members. As shown in Fig. 1 the bolt member 19 is spring-loaded and slides in a casing 18 and is retracted by a lever handle 21 pivoted to the casing. The keeper member 21 is slidable in a casing 24 and is biased by a spring 26 so that it tends to remain in the casing. The permanent magnet 29 is mounted on the casing 18 for the sliding latch bolt. In use when the door 1 to which the latch bolt 19 is fitted is closed, the bolt is retracted against the pressure of the spring 20 by engagement with the keeper 25 and when its end passes beyond the keeper it moves forwardly again under pressure of the spring, the permanent magnet 29 then attracting the keeper and any movement of the vehicle door relative to the body in a direction of the general plane of the door causes the keeper to move relative to its casing and the door still remains fastened since the latch bolt remains in position behind the keeper. In a second construction, Figs. 4 and 6, the keeper member is pivotally mounted on a pin 58 and the permanent magnet 62 is carried by the keeper member. The latch bolt member 48 is mounted in a casing 41 so that it can move beyond its normal position under the attraction of the magnet which it engages in the closed position of the door. When the door is closed the end of the bolt 48 engages the keeper member and pivots it against the pressure of a spring 61, the end of the bolt first engaging a safety notch 59 in the keeper member and then a fastening notch 60 in which position it is also engaged by the permanent magnet. To open the door the keeper member is pushed back by a member 63 which is operated from the outside of the door by means of a push-button which engages a bellcrank lever 70 or from the inside of the door by a remote handle through linkage and a lever 66.

Abstract: 290,355. Sinclair, J. R. Feb. 11, 1927. Vacuum tubes. - An insulating carrier for a filament cathode has a series of axial or helical ridges or cups formed by channelling the carrier, and the filament is wound under slight tension in notches in the ridges &c. so that a considerable length is supported between the ridges and only a small part is in contact with the carrier. The carrier may be of triangular or other polygonal form, and has an end cap and base for spacing other electrodes from the filament. The structure is mounted on a pinch. Steatite and porcelain are suitable materials for the carrier. Steatite is formed into shape when soft, and is hardened by heating to 1500‹ C. for an hour in an electric furnace; gas is removed by further heating to 1500‹ C. for an hour in a vacuum furnace. As shown in Fig. 1, a triangular carrier A with a central bore for receivng a support has three ridges a<1> with notches a<2> in which the filament is wound. A cap B with concentric stepped surfaces b<5>, b<4> is mounted on one end of the carrier, and the other end is formed with a spigot fitting in a base C with stepped surfaces c<5>, c<4>. A grid is spaced by the surfaces b<5>, c<5>, and an anode is secured in notches b<3>, c<3> in the surfaces b<1>, c<4>. In a modification, the carrier, cap and base are of rectangular shape, the grid being formed with rounded corners, and the anode having its corners sloped. The distance between the grid and filament is less at the points of suspension of the filament than elsewhere, thereby compensating for the lowering of the electron emission at those points. In the arrangement shown in Fig. 12, two grids G<1>, G<2> are' wound in notches in the carrier A between the notches for the filaments F. The anode H is spaced by the cap B and base C, and is formed in two parts with slots h<2> for receiving supports. In a modification of this arrangement, one of the grids is mounted on stepped parts of the cap and base, and is secured to two rods.
