Title: Improvements relating to embroidery frames for zig-zag sewing machines for the production of flat-stitch embroidery
IPC: D05B27/24
Filed: 1957-10-11
Abstract: 864,535. Sewing machines. ANKERPHOENIX NAHMASCHINEN A. G. Oct. 11, 1957 [Oct. 11, 1956], No. 31908/57. Class 112 In a zig-zag sewing machine an embroidery frame movable in two directions at right angles to each other is connected to a sensing element which can be guided along a pattern, and an adjusting element provided on the sensing element is operatively connected to the stitchwidth adjusting lever of the machine. The adjusting element may be moved by hand, or may terminate in a sensing element also engagable with the pattern for varying the stitch width automatically. As shown, a flat bar 2 is secured by a screw 3 to the sewing machine cloth plate, and carries externally of the latter a frame 22 containing a pattern plate 30. One arm of a rightangled bar 11 is connected by pivotal links 7, 8 to bar 2, and the other arm is connected by pivotal links 12, 13 to an embroidery frame 19 carried at one end of a bar 18. The other end of the latter carries a rivet 20 on which is pivoted a guide element 21 having a point 28 adapted to follow or sense one edge or side of recessed pattern 29 formed in plate 30. Also pivoted on rivet 20 is an adjusting element 21a having a sensing point 28 adapted to engage the opposite edge of pattern 29. An extension 21<SP>1</SP> of element 21 is connected to one end of a Bowden cable sheath 23, the other end of which is connected to a bracket 24 fixed by a screw 24a to the machine frame. An extension 27 of element 21a is connected to one end of the Bowden wire 23a, the other end of which is connected to the stitch-width adjusting lever 26. A spring 31 interposed between members 21<SP>1</SP> and 27 biases the sensing points 28<SP>1</SP>, 28<SP>11</SP> against their respective edges of the pattern 29, and a weaker spring 32 interposed between bracket 24 and lever 26 tensions the wire 23a.

Abstract: 803,161. Filters. CUNO ENGINEERING CORPORATION. Nov. 5, 1954 [May 4, 1954], No. 32028/54. Class 46. Axial spacing of a plurality of edge filter discs 38, 42, Fig. 1, stacked round a central post 14 and each comprising a central hub connected by spokes to an outer rim is effected by forming a portion or portions of the spokes with an increased effective thickness thereby providing filtering spaces between the rims of adjacent discs. The stack is capable of rotation with the post 14 whereby stationary scraper blades 30 mounted on a rod 26 and projecting between the discs serves to remove sediment therefrom. Alternate major and minor discs 38, 42 stacked round the post 14 have the inner edges of the rims of the major discs 38 in alignment with the outer edges of the rims of the minor disc 42 and the spokes of the larger discs are deformed to provide said axial spacing. Filtering apertures 82, Fig. 10, between outer edges 84 of minor discs 80 and aligned inner edges 86 of rims 66 of major discs 65 is effected by crimps 72, 74, Fig. 9, on true and false spokes of the major discs. The minor discs may also be crimped to provide larger filtering apertures. In a still further modification the stack comprises rimmed discs of equal diameter which are spaced by crimps running either transversely or longitudinally of the spokes. Specification 486,397 is referred to.

Title: A mixing valve for hot and cold water installations
IPC: G05D23/13
Filed: 1956-10-23
Abstract: 841,205. Fluid-pressure servomotor-control systems. CLAUSEN, M., [trading as DANFOSS VED INGENIOS M. CLAUSEN]. Oct. 23, 1956 [Oct. 4, 1956], No. 32274/56. Class 135. A hot and cold water mixing valve comprises a valve body 1, Fig. 3, having cold and hot water inlets 3, 4 communicating respectively with spaces 17a, 17b on opposite sides of a flexible separator 16 through which a spring-loaded, tubular valve member 15 sealingly passes, a mixing chamber 2 communicating with the interior of the valve member 15 a pressure chamber 6 separated from the mixing chamber by a flexible diaphragm 14 and a mixed water outlet 5, Fig. 2, leading from the mixing chamber. The valve member 15 which is fixed to a pin 19 engageable with the diaphragm 14 co-operates at its ends with seatings 18a, 18b to control the amount of hot and cold water admitted to the mixing chamber in accordance with the temperature therein detected by a bimetallic spring element 12. The element 12 which is fixed at one end to the valve body, carries at its other end a valve closure element 13 co-operable with an outlet nipple 10 from the pressure chamber 6 to which cold water from the inlet 3 is supplied through a restricted interchangeable nozzle 8. On, e.g. a decrease of temperature in the mixing chamber the bimetallic element 12 moves the valve element 13 to restrict the opening through the outlet nipple 10 thereby increasing the pressure in the chamber 6 to move the valve member 15 to the right to increase the amount of hot water and decrease the amount of cold water delivered to the mixing chamber. On an increase in pressure in the chamber 6 due to an increase in pressure in the cold water supply pipe the valve member 15 will again be moved to increase the supply of hot water and decrease the supply of cold water delivered to the mixing chamber. The operating temperature may be varied by the rotation of an eccentric cam 22 which bears against the bimetallic element 12 to adjust the initial position of the valve element 13 with respect to the nipple 10. A non-return check valve comprising a perforated body 33, Fig. 8, and a complementary disc 34 carried on a central rivet 35 is fitted in each inlet. The downstream face of the body may be flat or concave (as shown).

Abstract: 213,310. Murphy, L. Nov. 28, 1922. Motor power plant.-A variable-speed power plant for driving road or rail vehicles and other purposes comprises a prime mover, such as an internal-combustion engine or steam turbine, working with fixed throttle throughout the speed and torque range, and a second element, such as a dynamotor or engine-compressor, reversible in the power sense, the adjustment of the controls of this second element securing the torque variation over the whole speed range of the plant. Under certain conditions the second element may operate alone. Thus, a clutch 2 is provided between the internal-combustion engine 1, Fig. 1, and the dynamotor 3, which may have both armature and field controls, the source of electrical energy being either an accumulator on the vehicles or overhead wires, live rails, and the like. Fig. 2 shows a modification wherein an internalcombustion engine 1 is connected by a clutch 2 to an expansion engine 3 adapted to work alternatively as a compressor, in conjunction with a storage chamber 4 and, where the working vapour is not air, a pressure generator 5. In this case. the speed and torque variations of the plant are secured through the valve-gear of the expansion engine.

Title: Shock absorber

Filed: 1971-07-06
Abstract: 1358691 Fluid-containing shock absorbers JONAS WOODHEAD Ltd 6 July 1971 [6 July 1970] 32580/70 Heading F2S Only the final range of travel of a piston-rod 22 or 42 into a cylinder 23 or 44 of a shock absorber, e.g. of single or double type for a vehicle suspension system, is resisted by passage of fluid through an orifice 32, Fig. 3, or orifices 45-49, Fig. 7. The cylinders 23, 44 move in dirt shields 21, 41, fixed like the pistonrods 22, 42 to a connector 24, 43 for mounting the shock absorber. When the cylinder 23 slides up the rod 22, it is slowed by compressing a polyurethane cup 30 so that liquid is forced from its interior 27 through the orifice 32 into a metal chamber 26. With subsequent expansion of the cylinder and piston, the liquid is drawn back through orifice 32 and past a valve 33 opened by pressure difference. The chamber 26 may be omitted and the orifice and a valved opening both formed in the top closure of the dirt shield. A polyurethane cup, in this case attached against the closure, contains air to be forced out through the orifice on deformation of the cup. In Fig. 7, a rigid cap 40 is fitted around the end of the cylinder 44 and, when the latter rises, the cap enters and progressively distends (see Fig. 10) a synthetic rubber cap 55 which incorporates a reinforcement 58. Oil or oil-water emulsion is thus forced from a surrounding space 64 through the graded orifices 45-49 into a surrounding polyurethane sleeve 51 which distends to create a space 66, Fig. 10. A series of lips 65, which isolate the orifices 45-49 progressively during contraction of the shock absorber, allow return flow of the oil through all the orifices, as indicated in Fig. 10, during its expansion.
