Abstract: 1534513 Hydraulic control circuits DANFOSS A/S 11 Nov 1975 [12 Nov 1974] 46597/75 Heading F1P A member 3, Fig. 1, moved by an hydraulic motor 5, is slowed down and stopped by vertically slidable members 10, 11 which co-operate with stops 8 on blocks 7 and have orifices 31, 32, 33, 34, through which hydraulic liquid passes to the motor 5, which are moved out of alignment to throttle the flow of liquid to the motor as the position of rest is approached. In operation a valve 53, Fig. 2, is opened to supply pressure liquid from an accumulator 55 to chambers 13, 19 to raise the slides 10, 11 to a first position which is above the stops.8. This moves orifices 31-34 into alignment so that no throttling occurs. A valve 48 is now operated to actuate the motor 5. By means of a selector switch one of actuating switches 38a- 38d, e.g. 38c, Fig. 7 and thus one of the abutment devices 6 is selected. When this switch is actuated by the associated tappet 37c abutting the block 7, valve 53 is de-energized. Springs 20a, 20b now depress slides 10, 11 and the slide 10, Fig. 6 moves to a lowest second position whilst the slide 11 is held in a third intermediate position by the stop 8. This causes orifices 31-34 to throttle flow to the motor 5, thus retarding the member 3. Further movement of the member 3 leaves the slide 11 clear of the stop 8 so that it descends to the second position in which the valve 48 is de-energized. This is effected by switches 24, 25, 29, 30, Fig. 1. Slide 10 now abuts the side of the stop 8 and the member 3 is arrested.

A cine projector has coaxially mounted feed spool and take-up spool spindles 27, 17 in a common housing, one spindle being carried in a fixed part 2 of the housing to which is hinged at 6 another part 3 of the housing to which the other spindle is carried, one of the spindles being a drive spindle 17 friction coupled to the take-up spool 5 and having at the end facing the feed spool 4, an axially displaceable member which directly couples the drive spindle to the feed spool 4 during re-winding. Take-up spool 5 is carried on and pinned to a sleeve 7 wheel is mounted on, and pinned at 10 to the hollow shaft 8 rotatably mounted in a lever arm 11 pivoted at 13. Shaft 8 has a flanged disc 15 with a friction ring 14 drivingly engaging the drum 16 which is connected to the drive spindle 17 within the hollow shaft. A sleeve 19 is pinned at 20 to the other end of spindle 17 which projects from the hollow shaft 8, the sleeve having a flange 24 with apertures 23 which receive the pins 22 extending from a collar 21 slidable on sleeve 19. Collar 21 is spring-urged towards pin 20 which it engages in slot 26. The feed spool spindle 27 has at its end a displaceable clutch sleeve 31 spring-urged against pin 33 projecting from the spindle, in which position a driving connection is made through pin 35 and bore 36 with a friction disc 29 carried in a bearing bush 30 fixed to housing part 3. Feed spool 4 is pinned to disc 37 carried by spindle 27. In operation, part 3 is opened, a loaded spool is placed on spindle 27, and the film is threaded through projection part and anchored to take-up spool 5 which is driven as above when the housing is closed. The driven film rotates the spool 4 and also the spindle 27 and friction disc 29 which is braked by bush 30 to tension the film. Film tension on the take-up side is constant since the pressure of drum 16 against ring 14 depends upon the weight and the pivoted lever arm 11. To rewind, the housing is opened and collar 21 is manually released from pin 20 and rotated to shift the slot 26. The pins 22 then pass through flange 24 and enter bores 39 of feed spool 4, clutch sleeve 31 being first withdrawn to remove the braking effect of disc 29.

Abstract: 1,067,010. Finishing fabrics; yarns. FABRIC RESEARCH LABORATORIES Inc. Nov. 9, 1965, No. 47544/65. Headings D1K, D1S and D1W. An elastic textile fabric is made by (a) first constructing a dimensionally unstable textile fabric comprising an upper series of picks 30, Figs. 2-4 (all not shown), and a lower series of picks 32, a plurality of inelastic warp threads 34 at least some of which are interwoven with at least some upper picks 30 and some lower picks 32 and a plurality of elastic warp threads 36, and (b) mechanically compacting the fabric lengthwise. The initial length Li of any given piece of fabric when relaxed before processing is greater than Lc of this given piece after processing. The initial fabric has an initial closeness of construction less than that of the processed fabric by C per cent, C being substantially the normal wash shrinkage of the initial fabric, and an initial stretch Si which is less than the stretch Sc of the processed fabric and determined by the formula Si, Sc and C being expressed in percentages. The picks 30, 32 are preferably inelastic cotton threads and the inelastic warp threads 34, e.g. cotton, are woven so that side-by-side threads 34 pass over and under alternate picks and intervening picks. The elastic warp threads 36 preferably comprise rectangular crosssection rubber threads covered by tightly wrapped, spirally wound cotton threads 38, Fig. 5 (not shown), covered by a spirally wound thread 40 wound in a direction opposite to the threads 38. Nonelastic stuffer warp threads not interwoven with the picks may also be included in the fabric. As shown in Fig. 1, the fabric Fi passes over rolls 10, 12, 14 to a steam shoe 16 steam heated by a chamber 19 and which discharges steam through a felt 23, into the fabric Fi. The fabric is compacted by a contoured blade 17 into the nip between a driving roll 18 having a frictional web-gripping surface and a retarding roll 20 having a surface which is frictionally web-gripping to a greater degree than that of the roll 18. The compacted fabric Fc is dried by being pressed by a travelling blanket 24 against a smooth heated drum 26. The fabric may be treated with a finishing agent by a sprayer 42 before compacting but, preferably, it is treated after compacting by a sprayer 22 to avoid gumming of the shoe 16, the blade 17 and the rolls 18, 20 with the agent.
