Abstract: 1306060 Line projection apparatus EASTMAN KODAK CO 13 Feb 1970 [27 Feb 1969] 54500/71 Divided out of 1304221 Heading G2E In a sprocket-less cine projector, a film snubber 32 is provided comprising two flexible film-engaging arms 44, 46 extending radially from a hub 42, the snubber preferably responding to low frequency transients in film tension by pivoting on shaft 50 against spring loading, and essentially to highfrequency transients by resilient deflection of arm 46. A third response to transients may be provided by a viscous damping fluid 90 in a cavity 88 of hub 42. After projection, increasing tension of the film deflects arm 46 to trip a rewind button 38. During projection the supply and take-up spools are driven by a tendency drive to tension the film. Projectors with a reverse projection mode require a second snubber between the take-up reel and the gate.

Abstract: 1,179,070. Converter hoods; chimneys for converters. GOTTFRIED BISCHOFF BAU KOMPLETTER GASREINIGUNGS UND WASSERRUCKUHLANLAGEN K.G. and WAAGNER-BIRO A.G. 18 Nov., 1968 [2 Dec., 1967], No. 54536/68. Headings F4B and F4J. A suction hood 4 having an open-bottomed vortex chamber 8 surrounding its lower rim 6 is provided above and spaced from the mouth 3 of a converter 1 for the collection of waste gases therefrom. As shown, an outer ring 7 of the waste gases leaving the converter and deflected by the lower rim 6 into the chamber 8, together with any entrained air from the surrounding atmosphere forms a ring vortex 12. This vortex forms a protective screen in the gap 5 surrounding the mouth of the converter thus minimizing the escape of waste gases into the surrounding atmosphere while ensuring that too much air from this atmosphere is not drawn into the converter waste gases. In an alternative form (Fig. 2, not shown) the vortex chamber 8 incorporates a curved baffle (11) for splitting the ring vortex 12 into a plurality of superimposed vortices rotating in opposite directions. The suction hood and its vortex chamber may be cooled.

Abstract: 1,076,960. Clocks. KIENZLE APPARATE G.m. b. H. Dec. 23, 1965 [Dec.28, 1964], No.54545/65. Heading G3T. [Also in Division G1] A record chart carrier 13 and minute and hour hand shafts 21, 23 are driven in synchronism by a main spring in a barrel 3 and can be set simultaneously by turning a knurled knob 27 in either direction. The barrel 3 drives a bushing 8 through toothed wheels 4, 5, 6, 7 controlled through wheels 10, 11 by escapement mechanism. The bushing 8 drives the carrier 13 through a friction spring 12 and the carrier 13 drives the shaft 21, through toothed wheels 15, 17, 18, 19, 20, the wheel 18 also driving the shaft 23 through wheel 22. A closed gear train is completed by the carrier also driving toothed wheels 15', 17', 18', 19', 20. The wheels 18', 19' are interconnected by a volute spring 24 pretensioned in opposite sense to the driving direction so that wheel 18' drives wheel 19' only so far as the simultaneous drive of wheel 20 through wheels 15, 17, 18, 19 allows. Thus backlash is eliminated in the driving direction both when driving and setting and any backlash resulting while setting in the reverse direction is overcome before normal driving begins again.

Abstract: 1413295 Breaking pieces; furniture joints DEXION-COMINO INTERNATIONAL Ltd 7 Nov 1973 [27 Nov 1972] 54723/72 Headings F2M and F2X [Also in Division A4] Locking means for a connection between structural components, particularly for locking a connection between hooks 4 on a bracket 1, attached to a beam of a racking structure, and an upright component 3 of the racking structure, comprises a projecting part 20 passing through mating holes 6, 26 in the components to lock them against separation, the part 20 being adapted to fracture under a predetermined loading in two stages or at two locations and in such a manner as to indicate visibly that failure of the locking means has occurred. As shown, the locking means consists of an upper locating portion 8 and a locking portion 9 formed to provide the part 20, the portion 8 being of spring steel formed to clip on to the bracket 1 and to the portion 9, while the portion 9 is die cast from a zinc-base or aluminium alloy which will fracture sharply, under a predetermined upward loading. The part 20 is, as shown, of U form comprising a lower limb 21 which is thicker than upper limb 22, the two limbs being integral with a web 23. When the upward loading exceeds the predetermined value, limb 22 cracks first near its root and the lower limb 21 will generally crack also. As a result most of the lower portion 9 visible on the outside of the structure drops away so that failure is easily seen to have occurred. The hooks 4 are formed integrally on the bracket 1 and are of U section, the holes 6 in the upright component 3, which receive both the hooks and the locking part 20, being of diamond shape.

Abstract: 1281063 Feeding webs WINDMOLLER & HOLSCHER 11 Nov 1969 [2 Dec 1968] 55111/69 Heading B8R An arrangement for feeding a web B, e.g. of paper, plastics or textile material, under constant tension to a processing apparatus comprises a run-on roll 1, a run-off roll 2, an intermediate roll 3 and an adjustable pressure roll 4 which is mounted on pivoted levers 9 so that it can be selectively applied to press the web B against the roll 1 or the roll 2, or against both rolls 1 and 2 simultaneously. The considerable friction between the web B and the rolls 1, 2, 3 minimizes slip and permits feeding at substantially constant tension; if variations in the tension of the outgoing web portion, or the incoming web portion, or both web portions do occur, then slipping is avoided by pressing the web respectively against roll 1, or roll 2 or against both rolls. The levers 9 may be associated with a pressure-adjusting mechanism including a hand wheel 14, a screw 13 and a compression 16. The arrangement may be used to feed a web to a printing machine, in which case a second feed roll train, driven at an appropriate speed to maintain the desired tension in the printed web, may be provided downstream of the printing station (Fig. 2, not shown).

IPC: F01D17/16
Filed: 1965-12-29
Abstract: 1,125,333. Turbines. ROTOFLOW CORP. Dec. 29. 1965, No.55114/65. Heading F1T. In a turbine comprising a turbine rotor mounted in a casing and nozzle blades mounted on one side of each of two rings concentric with the rotor axis wherein one of the rings is fixed in the casing and the other ring is adjustable about the turbine axis to vary the size of the flow passages between adjacent blades, means are provided to assist sealing of the nozzle blades and to reduce frictional forces opposing rotation of the adjustable ring. In one embodiment, Figs. 2, 5, the nozzle assembly of a centripetal turbine comprises a fixed ring 14 integral with blade portions 15 surrounding the turbine rotor 10 and an angularly movable ring 16 bearing on ring 14 at 24 and carrying blade portions 17. Movement of ring 16 by means of a pivoted arm 28 having a roller 27 engaging a notch 25 in the ring causes the flow area between adjacent blades to be varied. Ring 16 has annular recesses 21, 23 communicating through a clearance 22 and supplied with highpressure fluid from the turbine inlet manifold (2), Fig. 1 (not shown). The fluid in recess 21 urges the ring 16 and blade portions 17 against a fixed cover ring 19 to assist sealing of the blades, whereas the fluid in recess 23 urges ring 16 radially outwards to reduce the frictional forces opposing rotation of the ring. A slit 26 also extends generally radially right through ring 16 in the region of notch 25 to further reduce frictional forces. In a modification, Figs. 11, 12, each nozzle blade 119 is formed in one piece and is pivoted on a pin 109 to a fixed ring 106. A slot 133 in the blade forms a guide track for a pin 126 carried by an angularly movable ring 112 so that movement of the ring 112 causes pivoting of each blade 119 to vary the flow area between adjacent blades. As before, recesses 113, 115 are supplied with high-pressure fluid from the turbine inlet to assist sealing and reduce friction and ring 112 has a slit (120, 122) in the region of its engagement with a pin (134) of an operating rod (135), Figs. 8, 10 (not shown). The generally radial slit in the movable rings may be of stepped form to reduce leakage and a stop, Figs. 16, 17 (not shown), may be provided to prevent excessive opening up of the slit. Figs. 14, 15 (not shown) illustrate nozzle blades of slightly modified shape compared with those in Figs. 11, 12.

Abstract: 554,199. Gyroscopic apparatus. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and MEREDITH, F. W. Nov. 21, 1941, No. 15018. [Class 97 (iii)] In an air driven gyroscope, the surround 11 encircling the rotor 10 is closer to the centre of the rotor periphery than to the sides and is provided with a number of inclined air jet passages 12 close enough together to provide a rotating ring of faster-moving air around the centre of the rotor periphery in order to effect a viscous drive. The increased space at the sides of the periphery improves the stream-line flow of the air and reduces the viscous drag on the rotor. This variation in space may be obtained by providing the surround and/or the rotor periphery with a curved surface. The periphery of the rotor is roughened or knurled over its central portion to receive the impact of the air from the passages 12.

Abstract: 131,042. Soc. Anon. des Etablissements Delaunay-Belleville. March 20 1916, [Convention date]. Breech actions, sliding breech-block. - Relates to cartridge-extractors for guns of the kind having a rotary bolt operated by anon-rotary sleeve, and consists in a special construction and arrangement of the extractor whereby, during the extraction, it is positively locked over the rim of the cartridge. The invention is shown applied to the automatic rifle described in Specification 127,642. The rigid non-rotary extractor 52 has an L-shaped projection 53 which enters a recess 54 in the bolt and engages under a ledge 55 covering part of the recess, the ledge being interrupted as shown in Fig. 2, to allow the extractor to rise to engage the cartridge when the breech is locked. In the position shown in Figs. 1 and 2, the breech is closed but not locked, and the extractor is held down by the ledge 55 and is slightly retracted by striking against the cartridge. When the bolt-operating sleeve 36 goes forward, the bolt is rotated, thereby bringing the interruption opposite the L-shaped projection 53, and a heel-piece 60 on the sleeve strikes the tail of the extractor, thereby driving its claw 56 forwards over the rim of the cartridge. When the breech is unlocked, the rotation of the bolt causes the ledge 55 to re-engage the projection 53, and the extractor is positively locked over the rim of the cartridge.
