Title: Improvements in and relating to gas control means
Inventor: BARNES HUGH VERNON
IPC: G05D23/12
Filed: 1959-08-12
Abstract: 897,134. Fluid-pressure servomotor-control systems. RADIATION Ltd. July 20, 1960 [Aug. 12, 1959], No. 27591/59. Class 135. Gas control means embodies a gas inlet 6, a valve 2 controlling the flow of gas through the inlet, a diaphragm 3 controlling the valve, a nozzle 12 supplied with gas from the inlet, and a Venturi throat 15 into which the nozzle discharges, one side of the diaphragm being in communication with the throat whereby the diaphragm may be subjected to reduced pressure caused by the flow of gas through the throat. When the main gas tap (not shown) is turned on gas passes through pipes 13, 16, the nozzle 12 and throat 15 to a pilot burner 10 creating, through a pipe 11, a small negative pressure in a space 8 between the diaphragm 3 and a smaller diaphragm 4 which also serves as a gland. The underside of the diaphragm 3 communicates with the atmosphere through an orifice 7, but the difference in pressure remains insufficient to open the valve 2 until a burner 10 is ignited to close a bi-metallically-operated valve 18 at the end of a branch pipe 17a. The leak through this pipe into the throat 15 is thus stopped to cause a further decrease in pressure in the space 8 to open the valve 2. Deliberate or accidental extinction of the burner 10 or the opening of thermostatically and time-controlled valves 19 and 20 respectively cause the valve 2 to close again by admitting air to the throat 15. The pipes 11 and 13 may be replaced by passages in the housing for the valve 2.

IPC: A43D21/02
Filed: 1926-07-15
Abstract: 284,179. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). July 15, 1926. Pulling - over. - In a shoe upper conforming machine, preparatory to the gripping of the margin of the upper, the inner jaw of the gripper is given a movement toward the shoe bottom and then a movement outwardly toward the edge of the shoe bottom. The outward movement is a swinging movement about an axis so located as to carry the jaw away from the shoe bottom. The invention is described as applied to the kind of machine described in Specifications 228,578 and 236,566. The gripper has an inner jaw 198, an outer jam 200, and is operated by an up-draw lever 218 and an over-draw rod 210. The cams operating these members are so formed that the end of the jaw 198 follows the path shown in chain line, first descending substantially perpendicular to the sole inside the insole rib, then swinging about the pivot 216 outwardly and away from the shoe bottom to clear the rib, then descending outside the rib but quite close to it, then a final movement to the edge of the insole, at which point the gripper jaws close. This movement enables the gripper to grip a lining or upper margin which may lie close to the insole. Specifications 283,978 and 284,185, also are referred to.

[Class 44] [Also in Group VII] A fastener for holding two pieces of pliable material A, B in edgewise contact comprises one or more stud fastener elements 2 secured on one piece B and each having a shank 20 projecting from the edge of the piece to engage a socket element 1 mounted in the other piece by being disposed between two plies of material, formed by the material A and a strip 3, secured together adjacent one of their edges but with a gap opening to the mouth of the socket. When the two pieces are provided with a series of such elements they may be connected by bringing the two pieces together in the plane of the material ; separation is effected by opposite transverse pulls on the two pieces as in a tearing action, Fig. 31. Figs. 16 and 17 show a socket element formed by spring sheet material bent upon itself at 4 to form upper and lower jaws 5, 6, the lower jaw 6 having a corrugation 8 to guide the stud so that the stud head 22 engages a recess 7 in the upper jaw 5. The lower jaw 6 is narrower and is cut back at 11 whereby shoulders are formed with the result that the upper ply of the material A lies flat as shown in Fig. 10. The socket elements are retained by a line of stitches 12 sewn through the edges of the plies with reinforcing threads 13 where the front edge of the socket element bears thereon by a turned-back portion 25, but leaving a gap 14 where the corrugation 8 presents its opening. A further line of stitches 15 is provided having reinforcing threads 16 around rear lugs 9 on the socket member. The stud elements have a bevelled-edge flat base 17 similarly retained between plies of material by stitching. The stud head 22 is of ball-like shape standing up from the flat taper shank 20 which may lie at an angle to the plane of the base 17 so as to conform to the contour of the surface on which the fastener is lying. The flat taper form of the shanks 20 causes the stud element to be automatically forced out once the shank has been rotated to spread the spring jaws of the socket: The fastener is applicable to furniture covers and corsets.

Abstract: 1509055 Sewing machine, work feed PFAFF INDUSTRIEMASCHINEN GmbH 3 July 1975 [6 Sept 1974] 28027/75 Heading D1G A sewing machine having a needle 10 which swings in the work feeding direction has two feed dogs 31, 34 which engage the work alternately during a stitching operation, each moving the work through half the stitch length. The reduced amplitude of motion of each dog and its driving gear and their out of phase motion is stated to allow higher stitching speed and to reduce vibration. Feed bars 32, 35 carrying respective dogs 31, 34 are moved directly by feed lift eccentrics 37, 38 which are 180 out of phase and indirectly through adjustable stroke mechanisms by feed advance eccentrics 42, 41. The mechanisms are of the swinging link type in which the stroke transmitted depends on the misalignment existing between shafts 56, 59 and between shafts 48, 51 respectively. The misalignment is dependent on the angular position of a shaft 50 which also controls the swinging link mechanism 13 providing an adjustable work feeding swing to the needle bar gate 9 pivoted to the machine frame at 8. In the latter mechanism the shafts to be misaligned are 17 and 22. Shaft 50 is rotatable by a control wheel 71 having a diverging cam-slot 71a one side of which is normally engaged by an end of lever 69 connected at its other end to a crank 61 on shaft 50. Depression of a lever 74 moves lever 69 to place its end against the other side of slot 71a to reverse the feeding direction. A feeding foot may be provided which partakes of the needle movement and is effective only during the action of feed dog 31. It is stated that the action of the second feed dog 34, occurring after the needle has risen from the work and the take up lever (75, Fig. 2 not shown) has reached its highest point, completes the setting of the stitch.
