Title: An improved high pressure fluid filter
Inventor: GUTKOWSKI JANUSZ
IPC: B01D35/00
Filed: 1958-04-21
Abstract: 843,237. Filters. PARMATIC ENGINEERING Ltd. April 21, 1958, No. 12588/58. Class 46. A combined shut-off- and relief-valve spigot body 17, Fig. 2, for incorporation in the head 11, Fig. 4, of a filter, includes a piston 54 slidable in a bore 57 in the head, and a flange 44, and it is shown in its uppermost position in Fig. 4, where pressure greater than normal in the inlet chamber 39, communicating around flange 44 (spaced from the inlet chamber wall) with bore 57, has acted upon the underside of piston 54 to overcome combined outlet and spring-pressure upon the upper side. Incoming oil from 12 passes between relief-valve member 45 and its seat 35 (provided on a conduit 19 fixed to the filter element 21), through the bore 48 of spigot body 17 and through vents 49 near its top to outlets 13, 15 and also through ports 52 and tube 53 to outlet 14. During normal flow conditions the spigot body is held down by spring pressure on to the seat 35 so that oil must flow past spider 20 to and through (arrow A) the filter element 21 to reach the inside of conduit 19, whence flow is as before. On unscrewing the filter bowl 10, (the element being secured therein), the spigot body is forced by the spring 64, 65 into its lowermost position, Fig. 3, in which inlet-space-shut-off-valve 46 is on annular seat 70 and outlet-space-shut-offvalve 51, (see Fig. 2), engages valve surface 75.

Title: Improvements in or relating to tandem toggle presses
Inventor: KAUL JOSEPH ISADORE
IPC: B29C45/68
Filed: 1955-05-02
Abstract: 771,846. Casting - machines; moulds. NATIONAL LEAD CO. May 2, 1955, No. 12707/55. Class 83 (1). [Also in Group V] A toggle-press casting-machine comprises, Figs. 2 and 3, a stationary plate 12 and a sliding plate 14 (between which the mould-sections 50 are forced together), a fixed end-plate 16, a slidable centre-frame 18, toggle-linkage 20 operated by a crosshead 22 for moving the plate 14, and toggle-linkage 24 operated by a crosshead 26 for moving the frame 18. Linkage 20 connects plate 14 to frame 18, and linkage 24 connects frame 18 to fixed end-plate 16. The crossheads are moved by a hydraulicallyoperated rod 30 which is secured at its righthand end to crosshead 20 but is slidably disposed in crosshead 26. Two lost-motion collars 32, 34 are fixed to rod 30. When rod 30 moves to the left from the closed position shown in Figs. 2 and 3, the rod moves crosshead 22 to the left without, at first, moving crosshead 26. Rod 30 slides idly through 26 until collar 34 reaches 26, whereupon 26 also moves left. This leftward movement of crosshead 26 occurs before crosshead 22 reaches frame 18. The final, open position is shown in Fig. 8. On the closing movement, crosshead 22 again moves before crosshead 26 moves, the latter remaining stationary until it is taken up by the collar 32, and both toggles reach the closed position of Fig. 2 simultaneously. Details. The plate 14 and frame 18 slide on four tie-rods 40. The crossheads slide on rods 70 secured at their forward ends to plate 14. Plate 16 is adjustably locked on rods 40 by nuts 48, and to facilitate adjustment, it has rollers 58, 60 which run on rails 42. The plate 14 and frame 18 also have rollers 46. Plate 12 is fixed to the rails 42 at 44. The press shown is a cold-chamber die-casting machine having a hydraulic shot-cylinder 74 secured to the rails by pedestal 75. Modifications. (1) (Figs. 4 and 6, not shown). The frame 18 may be locked in advanced position on the rods 40, the collar 34 being removed and the toggle 24 being fixed, this giving a short mould-opening stroke. A minimum-stroke may be obtained by limiting the travel of plate 14 by stops on the rods 70; (2) (Figs. 5 and 7, not shown). An intermediate mould-opening stroke may be obtained by interposing stops on the rods 70 between plate 16 and crosshead 26. (3) Each of the toggles shown may be duplicated.

Patent GB-638300-A (GB)
Title: Improvements in or relating to apparatus for testing toothed gears
IPC: G01B5/20
Filed: 1947-05-13
Abstract: 638,300. Testing toothed gears. MULLER, K. May 13, 1947, No. 12927. Convention date, May 14, 1946. [Class 106 (ii)] In an apparatus for testing gear wheels or worm-gears according to the one-flank meshing method (i.e. in which only one set of gear tooth flanks is tested at a time), the meshing test wheels (or gears) 6, 7 are connected to cylindrical discs having together a transmission ratio equal to that of the wheels, two of the discs roll on two parallel bars 13, 14 respectively, when the wheels are moved parallel to the bars, and one of the bars is longitudinally displaceable and the other not, the displaceable bar 14 being connected to a recording device 28. As shown, spur wheels 6, 7 are rotatably mounted on a carriage 2 movable over the bed 1 of the apparatus by means of a spindle 3, the wheel 6 being mounted on a transversely movable part 4 adjusted according to a scale 32. The bars 13 and 14 are mounted on carriages 15, 16 and 22, 23 respectively which are displaceable by means of spindles 17 &c. and bevel gearing, to press the bars on discs 11, 12 mounted on the spindles for the wheels 6, 7. The bar 14 has an arm 24 at one end which acts on the lever system 25, 26 so that the longitudinal displacements of the bar are magnified and recorded on the rotating drum 28. In use, a spring-pressure applying device 35 at the other end of the bar 14 is adjusted so that the appropriate tooth flanks of the gear wheels interengage, and lever 25 is adjusted to bring a pin 27 above the centre of the drum. The carriage 2 is then moved by spindle 3 so that the disc 11 rolls on bar 13 to rotate wheel 6 which drives wheel 7 and hence disc 12. Any difference between the speed of discs 11, 12, due to faults in the gear wheels, will cause movement of bar 14 and thus a displacement of the pen 27. The drum 28 is rotated when the carriage 2 moves by a rack 31 and gearing 46, 30, 29. The apparatus may be modified for testing bevel wheels, in which case one of the wheel spindles is horizontal and both wheels are adjustable on the carriage 2. In a further modification for testing worm gear, the disc 11 is driven indirectly from bar 13 through transmission gear comprising additional discs. As shown in Fig. 5, the lever 26 has a catch 43 to move hands 41, 42 over a scale 44 to indicate the maximum oscillation of the lever in either direction.

Title: Suturing ring for an implantable prosthetic device and a process of making the same
IPC: A61F2/24
Filed: 1973-03-19
Abstract: 1431351 Artificial heart valve suturing rings MEDICAL INC 19 March 1973 [17 March 1972 11 Aug 1972] 13021/73 Heading A5R A suturing ring for securing around the outside of an implantable prosthesis e.g. the housing 21 of an artificial heart valve, comprises a porous cover 46 of toroidal shape, a cured plastics core 47 and a heat - shrunk plastics sleeve 51 for holding the cover against the outside of the prosthesis. The ring is made by placing a tube of woven synthetic fibre cloth for the cover 46, around the housing 21 for the cover 46. The sleeve 51 which is preshrunk is placed around the cover 46 so that it will hold the cover against a peripheral groove formed by flanges 24, 25 of the housing 21. The sleeve 51 is further tightened against the cover 46 and the valve housing 21 by threads 57, 57A, 57B and heat shrinking. A roll of uncured core material, e.g. fluorosilicone rubber, or predetermined weight is disposed around the sleeve 51 and threads and enclosed by the cover 46, the ends of the tube of cover material being secured together to impart a toroidal shape to the cover by stitches 48. The heart valve with the ring attached is pressed into the cavity (61) of a mould (59) Figure 9 (not shown) the walls of the cavity (61) being shaped according to the desired finished shape of the ring. The mould is heated to cure the plastics core 47 and further shrink the sleeve 51. During heating, the cover 46 is bonded to the core 47 but retains its porous characteristics so that, when the valve is sutured into the heart, tissue can grow into the cover. The valve housing 21 and the ring are relatively rotatable so that adjustment can be made during placement of the valve in the heart. The cover 46 may initially comprise a sheet of porous plastics material formed into a tube by a longitudinal seam and has threads sewn into it for tightening it against the housing 21 before the sleeve 51 is applied. The heart valve 20 described has a pivotal disc valve member 22 and is substantially as disclosed in Specification 1388064. Reference has been directed by the comptroller to Specification 1375977.
