Title: Improvements in or relating to stop motion mechanisms for circular knitting machines
IPC: D04B35/10
Filed: 1949-07-27
Abstract: 686,756. Knitting-machines. BECKETT, S. F., and LEVEY, L. July 11, 1950. [July 27, 1949] No. 19706/49: Class 74 (ii). In or for a circular knitting machine having electric stop motion mechanism, there is provided cut-out means operable to render the electrical mechanism operable or not according to whether the machine is in motion or stopped and constructed and arranged for automatic operation by the machine fabric. Contacts 32, 33, in series with yarn dropperoperated contacts 2, 3 controlling a machine stopping solenoid 4, are held closed by the drag of the fabric 7 when the machine is operating, but are opened by a spring 39 when the machine stops. The movable contact 35 is on one end of a feeler lever 34 having a curved fabricengaging edge 38. The solenoid 4, when energized, moves a rod 5, to bring a cam 14 from under one end of a bell crank-lever 15 allowing the other end 15<SP>1</SP> thereof to engage teeth 16 on a collar 17 rotatable on, but axially located on the driving shaft 19. The collar 17 is normally rotated by the reaction between the inclined face of any one of ramps 18 carried thereon and a peg 20 on another collar 21 slidably keyed to a shaft 22 and spring-urged upwardly to mate dogs thereon with dogs on a collar 120 driven by shaft 19. The machine is thus normally driven through shafts 19 and 22 and gears 23. When the collar 17 is stopped by the lever 15, the pin moves down the ramp, forcing the collar 21 down against its spring 26, to disengage the clutch. The collar 21 is held .in that position by the end 29 of a bell-crank lever 27, which climbs the chamfered face 30 of a rib 25 and moves in behind the rib. The clutch is engaged again by manual depression of the end 31 of the lever 27. The slight delay before the fabric closes contacts 32, 33, when the machine is started, prevents stoppage before at least a few courses have been produced.

Title: Process and apparatus for thermal deposition of metals or other materials
IPC: C23C14/24
Filed: 1937-07-16
Abstract: 485,965. Fusing and working silica. ALEXANDER, P. July 16, 1937, No. 19772. Convention date, July 17, 1936. [Class 56] [Also in Group II] In depositing coatings of metal or other material, e.g. quartz, by evaporation in vacuo, the rate at which the material to be evaporated is fed towards the heater is so low and the temperature of the heater is so high that the material is evaporated substantially as soon as it contacts with the heater. An inert gas, e.g. hydrogen, may be fed into the chamber to replace the residual air, and the residual gas may be ionized. In the form shown in Fig. 1, the material to be evaporated is in the form of a wire or strip 18 which is fed from a roll 19 so that its end contacts with the heater 16. The material is at once vaporized to form a coating on the surfaces 22 and 23. Inert gas may be introduced at 32 and the residual gas ionized by the electrodes 26, 27. In coating small surfaces a straight wire or strip may be placed in the guide 33 so as to rest on the heater, the wire or strip being fed down by its own weight. Fig. 2 shows a device, e.g. for use with quartz, where the material is fed in granular form, being carried from a hopper 34 at a predetermined rate by a conveyer 35 to a hopper 36 which feeds it on to a U-shaped heater 38. In another form, the heater may be a hollow body, e.g. a cylinder, made of wire gauze or perforated metal, a wire or strip of the material being fed into the body through a hole or slit. To coat large surfaces a plurality of heaters may be used, and Fig. 3 shows a device in which a plurality of heaters and feeding-devices is mounted on a bar 40 which can be moved up and down on guides 42, adjacent the surface 43 to be coated. In coating long flexible surfaces, such as paper strips, these may be contained on rolls which feed them past the source of vapour. The low density of the vapour enables a relative]y low vacuum to be used ; e.g. aluminium may be vaporixed in a vacuum of 10<-3> mm. of the temperature of the heater being about 1500 C.
