On application of the brake with normal slack lever 2 moves anti-clockwise to move collar 15, sleeve 14 and, through clutch a-a the nut 12 spindle 11 and brake shoe 7. If the slack is too great however the distance A is taken up before the end of the piston movement and further leftward movement of the locking ring is prevented, disengaging clutches b-b and c-c, the spring 22 causing nut 13 to rotate on the moving spindle until c-c is re-engaged at the end of the stroke. The gap then existing between surfaces b-b represents the required adjustment and is taken up on the release stroke of the piston as spring 29 returns level 2, the nut 12 spinning, as clutch a-a is then opened, until the movement of sleeve 14 is terminated by flange 17 engaging nut 13 to engage clutch b-b. Manual adjustment of the nuts 12, 13 is possible by rotating the slotted sleeve 14a which engages the sleeve 14 and lugs 25 on the looking ring 21. A hand brakeoperated lever 30 is also provided. In a second embodiment (Fig. 3, not shown), the locking ring is rigidly fixed to a sleeve having a cover and which extends within a cylinder element secured to the cover. The Clearance A is provided between the edge of the cover and a split ring positioned within the cylinder element.

Title: Method of and apparatus for opening flattened tubes of flexible sheet material
IPC: B31B50/80
Filed: 1968-08-21
Abstract: 1,240,300. Making bags. WINDMOLLER & HOLSCHER. 21 Aug., 1968 [1 Sept., 1967], No. 39896/68. Heading B5D. To facilitate the opening of plastic or foil tubes during the formation of cross-bottom bags from tubular material, the layers of sheet material are separated by a few millimeters by the aid of suction means. Air, which may be ionized, may be blown between the separated layers and even if the layers subsequently touch they will open readily when the cross-bottom is to be formed. One form of apparatus for separating the layers comprises suction tables 4, 5 moved apart by a cam 11 on a drive shaft 10 synchronized with mechanism driving a gripper chain 1, 2, so that the layers separate while the tube is stationary. A switch 17 and valve 16 connect the tables to a vacuum pump 15. In another embodiment (Figs. 3-7) the tables are stationary and are set at a slight angle to one another, a perforated moving belt passing over each table. The separation of the layers commences adjacent a fold in the flattened tube and continues progressively across the tube width. In a third embodiment (Figs. 8, 9) the layers are separated by a pair of suction rollers rotating at a speed corresponding to the speed of linear travel of the flattened tubes. These separating devices are mounted on a plate whose position can be adjusted by screw means to accommodate tubes of different length.

Abstract: 1,117,394. Conveyer systems; chains. SI HANDLING SYSTEMS Inc. 20 Sept., 1965 [23 Oct., 1964], No. 39916/65. Heading B7L. [Also in Divisions B8 and F2] An endless conveyer 13 moving in a channel in the floor of a building comprises a chain having a dog-section including a chain link 14 providing a pushing surface 28 at one end for engaging a tow pin 12 of a vehicle movable along said floor, the pin 12 depending into a slot in the floor above the channel. The dog section comprises a downstream block link 16 inclined at 18 to lift the pin 12 on to the dwell surface 22 of the following two side bar link 20 or a block link 24 providing a recess into which the pin 12 moves to be engaged by the pusher surfaces 28 of the two side bar link 14. The upstream portion of the dog section is also provided at 34, 30, 31 with inclined and dwell surfaces to provide for a tow pin moving faster than the conveyer. The chain links are coupled by pins passing through elongated holes in the links, which permits arcuate movement of the chain in the horizontal plane. The chain moves along a wear plate 48 in the bottom of the channel which may at spaced intervals have a roller 38 projecting therethrough. During arcuate movement the side of the chain may engage a wear plate (114) Fig. 17 (not shown), or a roller, Figs. 4, 6, 18 (not shown). The drive for the conveyer chain, Figs. 20, 21 (not shown), comprises a pair of driven sprockets spaced along the conveyer length, and over which the chain is looped, the chain coming out of the loop being displaced laterally from the chain going into the loop. The sprockets are movable relative to each other to adjust the tension. The tow pin slot is accordingly displaced with jog section between the two parallel displaced sections, the tow pin moving through this jog section under the vehicle inertia. A receptacle (118), Fig. 19 (not shown), is placed in the system to receive debris scraped along the wear plate 48 by the chain. Detailed variations in chain construction are illustrated in Figs. 7 to 16 (not shown).

IPC: H01S3/07
Filed: 1969-08-11
Abstract: 1279161 Lasers GENERAL ELECTRIC CO 11 Aug 1969 [27 Aug 1968] 40031/69 Heading H1C Thin rectangular elements 1, Fig. 1, of laser active material such as ruby or neodymium doped glass are arranged in a zig-zag pattern, separated by and in optical contact with prisms 5, 5<SP>1</SP>, the body so formed being pumped by flash lamps 2 disposed to the sides of the axis of emitted laser radiation. Alternatively a single element optically contacting a pair of prisms may be used (not shown). Glycerine may be placed on the elements' major faces, to reduce the requirements for optical flatness of the faces. The lamps are backed by alumina reflectors 6, and mirrors 4 may be provided to prevent pumping radiation entering the edges of the elements. A filler (not shown) may be used to eliminate infra-red and ultraviolet pumping wavelengths. Prisms 5, 5<SP>1</SP> direct the pumping radiation uniformly on to the elements 1, and the body may be used as a generator by provision of mirrors 9, 10 or dielectric coatings at the ends, one such reflector being partially transmitting at laser output frequencies. The flash lamps at one side of the body may be replaced by a plane mirror. In Fig. 3, the elements are cooled by a liquid having a refractive index substantially matching that of the active material, as described in Specification 1,274,491, and alternative end prisms 5<SP>1</SP> made of a glass of refractive index at least #2 are shown. A more uniform pumping radiation density is achieved by placing the flash lamps away from the body, loss of the radiation being prevented by a light pipe, that is a totally internally reflecting glass block such as 13. In Fig. 5, right angled prisms 20 of refractive index at least #2 are used, as described in Specification 1,274,550, to concentrate pumping radiation on to the elements, but since due to optical contact at face 21 not all this radiation will be totally internally reflected at the upper and lower faces of prisms 5, 5<SP>1</SP>, these are provided with mirros such as 24. The folded path technique described in the above Specification 1,274,550 may be applied to the body by addition of suitable prisms at its ends, Fig. 6 (not shown).

Abstract: 1357109 Selective signalling STAVELEY INDUSTRIES Ltd 19 Aug 1971 [24 Aug 1970] 40652/70 Heading G4H An electronic filter includes a chain of gates G, H, I, J arranged in an operating cycle initiated by an input pulse to be triggered open in turn each for a set period, a succeeding gate opening as a preceding gate closes, and means F for supplying operating pulses initiated by successive input pulses to all the gates, so each gate recognizes a respective sub-band of frequencies. Each input pulse (which may be received by radio) produces a pulse from a monostable A the leading edge of which triggers a pulse generator F to apply a short pulse to gates G, H, I, J, and the trailing edge of which initiates a chain of monostables B, C, D, E to open the gates G, H, I, J in turn so that the short pulse from F produced in response to the next input pulse will pass to one of four pulseintegrating - detector - and - stretchers K, L, M, N, according to the prf. of the input pulses. The latter unit produces a machine-tool-control on/off output after receiving a predetermined number of pulses, and may be insensitive to some pulses omitted (permitting two output channels to be controlled simultaneously by applying the input pulses at the two prfs. required alternately). Generator F is inhibited by a clamp O until a detector P has detected at least 5 successive input signals with a mark/space ratio of over 80%.
