Abstract: 1383607 Pile-wire mechanism V COURTENS 6 Nov 1972 [9 Nov 1971] 50982/72 Heading DIE A device for inserting and withdrawing pilewires in a loom for weaving pile fabrics, comprises a carriage 22, 29 for engaging the pilewires, a guide 25 for the carriage extending substantially parallel to the loom tread beam, a pile-wire guide 27 pivoted at one end for movement towards and away from guide 25, such that in use the carriage is moved by chain 3 from a position opposite a chain wheel 1 to a position opposite a chain wheel 2 and guide 27 is simultaneously moved against guide 25 so that mechanism on the carriage can be actuated to engage the pile-wire in the fabric furthest from the reed. The wire moves inside a groove 28 formed in the guide 27. Continued movement of chain 3 causes the carriage to withdraw the engaged pile-wire from the fabric, the wire having a knife which cuts the pile warp loops lying over the wire. Guide 27 is then moved away from guide 25 and the carriage pushes the pile-wire back into the warp shed of the loom. Chain wheel 2 is driven via a chain 11 by a chain wheel 8 rotated by an eccentrically disposed crank 21, and slot 14 such the chain 3 is successively accelerated and decelerated during insertion and removal of a pile-wire.

A clutch-brake comprises a plate 15 acted on by springs 16 bearing against a part 18 adjustably held against axial movement, to grip a disc 11 with loose friction inserts 12 between plate 15 and a plate 14, the plate 15 being withdrawn by air pressure acting on an annular diaphragm 22 engageable with annulus 23 fixed to part 18. The part 18 is connected to an annulus 26 secured to four extensions 27 of a gear wheel 28, the plates 14, 15 being splined at 44 to extensions 27. The gear wheel can be driven by motor 41 and can be braked by a magnetic brake 42. Each extension 27 has a plunger 32 which can be moved by air pressure into the path of abutments 37 on disc 11 whereby the extensions 27, plates 14, 15 and disc 11 are locked together. Normally the plungers are withdrawn and brake 42 applied to hold plates 14, 15, the springs acting to brake disc 11. To drive a shaft 10 and a press, the motor drives plates 14, 15 and disc 11 is either frictionally engaged for low torque or engaged by plungers 32 for positive drive. Motor 41 is supplied from a three-phase mains, Fig. 3, not shown, through a star-delta equipment; in one position of a two-pole switch, the star connection can be held so that the motor can be inched under the control of forward and reverse push buttons at a reduced output torque for tool setting, and in the other position, to effect a full pressing operation, the motor starts with the star connection and automatically changes to delta connection after a predetermined time; this latter operation can only take place if the pressing mechanism is within a certain range of topdead centre; if not the press must be inched into this range. The change to delta connection takes place by the time the motor reaches full speed.

Title: Sliding plug door mechanisms
IPC: E05F11/53
Filed: 1975-12-20
Abstract: The door-control device, designed especially for driving a vehicle sliding door from the underside of the latter, possesses a rocker arm (5) with a first cam guide (18) and a fixed cam part (10) with second cam guides (11). A common cam-follower part (12), which simultaneously engages into the two cam guides (18, 11) and which is movable by a crank (15) driven in rotation via a shaft (16), fixes, in dependence on the rotary position of the shaft (16), the relative position of the rocker arm (5) in relation to the fixed cam part (10) in any pivoting position of the rocker arm. This results, in any rotary position of the shaft, in a positive locking and securing effect for the rocker arm (5) and the fixed cam part (10). <IMAGE>

Abstract: 1355670 Photographic reversal processes AGFA-GEVAERT AG 17 Nov 1971 [17 Nov 1970] 53280/71 Heading G2C A photographic reversal process for producing positive images comprises (a) imagewise exposing a light-sensitive silver salt emulsion, (b) developing to produce a negative silver image, (c) treating with a compound containing a peroxo group e.g. a peroxide, perborate, percarbonate, persulphate, organic peroxide or a urea/H 2  O 2  compound, to decompose the compound in the silver image areas, (d) forming a positive image by decomposing the remaining peroxide in the presence of a substance which catalyses the decomposition less strongly than the silver image and then rendering the image visible by forming a vesicular image or by an oxidative colour change with a suitable reaction component. Preferably the silver image is then bleached out. Specified catalytic substances for step (d) are (i) nuclei of Cu, Ag, Au, Fe, Co, Ni, Ru, Rh, Pd, Os or Pt either present initially in the layer or produced by fogging development or (ii) a protein as in Specification 1332692 initially present in the layer. In the examples, a silver halide emulsion is imagewise exposed and developed with a fogging developer, treated with a peroxide bath and left for 20 seconds so that the fogged, unexposed areas can decompose the peroxide, treated with a solution containing 2-amino-5(N-ethyl-N-ethoxyamino) tolmene or 1, 7 dehydroxynaphthalene or heated (preferably hydrazine is added to the peroxide treatment) to produce a coloured or vesicular image respectively. The silver image is then bleached out. Alternatively, a colloidal metal sol e.g. Ag, Au, Pc, Pd, Os or Ir may be added to the silver halide emulsion and a non-fogging developer is used. The silver halide emulsion may contain a colour coupler in which case the coloured image is produced by using a colour developer.
