Title: Flier for roving machines
IPC: D01H7/32
Filed: 1966-04-22
Abstract: 1,114,065. Roving flyers. ZINSER-TEXTlLMASCHINEN G.m.b.H. 22 April, 1966 [22 April, 1965], No. 17745/66. Heading DID. In a roving flyer, first and second torques are applied to the pressing-finger; the first torque wholly or partly offsets, at all stages of the wind, the tendency of the finger, under centrifugal action, to turn about its axis out of contact with the package, while the second torque presses the finger against the package. The magnitude of the second torque may be adjustable to suit the speeds at which the flyer may rotate; once so adjusted, it may remain constant throughout the wind, or it may vary as the wind proceeds. The first torque may be produced by a counterweight, 19, Fig. 4, on an arm fixed to the rod 13 on which the finger is mounted, the arrangement having characteristics set out in Specification 1062217, so that in all positions of the finger it applies to the finger a turning moment which offsets that arising from the centrifugal force acting at its centre of gravity as the flyer rotates. The second torque may be applied by a spring, the force of which remains constant as the finger moves outwardly as the package grows, or by hydraulic, pneumatic, or electromagnetic means or by an eccentric weight. When a weight is employed, it acts on the finger-axle 13 through a lever 31 fixed on the axle at an angle relatively to the flyer so chosen that the torque applied by the weight as the flyer rotates is constant whatever the angular position of the finger during the wind. In Fig. 4, the weight includes a member 27 slidable on rods fixed in the flyer, and, so that the torque can be adjusted to suit the speed at which the flyer rotates, the member 27 is connected to a threaded rod on which the position of a supplementary weight 29 can be adjusted. An aperture in the flyer wall gives access to the rod and a scale is provided to indicate the setting. In Fig. 5, the weight 41 is adjustable along a threaded rod rotatable about a vertical axis 43 parallel to, but offset from the axis of rotation of the flyer. When it is desired to vary the torque during a wind the lever 31 is replaced in Fig. 4 by a cam plate 56 which is connected to the weightmember 27 by a cord 55 in-contact with the face of the cam; in, Fig. 5, it is replaced by a plate 31" having two apertures 46, 47, in either of which can be inserted the tie-member 45 which connects the plate to the threaded rod (40). In these forms, the flyer is bell-shaped and may be of plastics material with integral balancing-members and apertures for access to broken rovings; the torque-producing members are disposed in the upper part of it which is sealed against the ingress of flyer. A tubular guide, Fig. 6 not shown, may be provided to guide the roving to the finger. A form is described, Fig. 7, not shown, when the flyer has two arms, and the weight is adjustable along a rod that is adjustable in a threaded socket, and is rotatable, as the flyer rotates, about an axis parallel to, but offset from the flyer-axis.

Title: Textile spinning rings
Inventor: TALLIS HENRY CHARLES HINTON
IPC: D01H7/62
Filed: 1965-04-29
Abstract: A spinning ring comprises a traveller-bearing surface at least part of which is made of "rubber material", which is defined as natural or synthetic material which can recover from large deformations quickly and forcibly.  It should be of high tensile strength, resilience, hardness and resistance to lubricants, wear and corrosion, and be capable of bonding.  It should be capable of treatment, vulcanizing, or curing, to develop these properties, and may include accelerators, fillers or reinforcing agents.  It may be a coating on a base of, e.g. rubber or steel; it may be compounded of more than one material, or it may be a coating developed by fluorination or graft polymerization.  The material may be foamed rubber having a substantial proportion of the interstices in communication with one another so that fluid lubricant may be applied to the traveller-bearing surface by permeating through the material under capillary action or externally-applied pressure.  The material may be one wetted by the lubricant.  The material may be in the form of one or more inserts, which need not be level with the upper and lower parts of the body to prevent damage when the traveller is put on or taken off, or the body may support a rubber ring.  Examples of suitable synthetic materials are polymerized di-enes such as polyisoprene, polychloroprene, co-polymers of ethylene and propylene, of styrene and butadiene, of acrylonitrile and butadiene, polyisobutylene, chlorosulphonated polyethylene, polysulphide rubbers, silicone rubbers, and fluorinated rubbers.  In Figs. 1, 2 and 4, not shown, a ring is of rectangular section and is held in the holder by an integral horizontally-extending ring.  The ring may be of rubber or comprise a steel body with an annular rubber insert, e.g. of foamed rubber supplied with lubricant by a pump.  In Fig. 3, not shown, a wick is position in an annular groove on a rubber ring with one end of the wick dipping into a reservoir formed in the rail.

Abstract: 1,088,215. Turbine plant condensers. MASCHINENBAU-BALCKE A.G. April 26, 1966 [April 27, 1965], No. 18220/66. Heading BIB. Exhaust steam from a turbine 1 is condensed in a condenser 3 by indirect cooling with ammonia or some other liquid which has a high heat of vapourisation, a low melting point, and a high saturation vapour pressure at ordinary condensation temperature of the exhaust steam, the ammonia or other liquid which is vapourised by the steam condensing being fed via line 5 to an air condenser 6 and the condensate then recycled to the condenser 3. The condensate after leaving the air condenser 6 flows into a collector 8 and thence by gravity or by a pump to the condenser 3, a regulator 9 controlled by the liquid level in the condenser 3 being present in line 4. The pressure of the fluid is substantially the same at all point of its circuit, and the vapour conduits are of small construction due to the fluid occupying a relatively small volume.
Patent GB-182368-A (GB)
Abstract: 182,368. Runbaken, J. H., and Torrance, W. Sept. 8, 1921. Indicators actuated by pressure of head of liquid; alarms. - A liquid-level gauge or indicator comprises two mechanically interconnected differential capsules b, d, Fig. 6, upon the larger b, of which the liquid in a storage tank, e.g. a petrol tank ot a motor car, acts so as to displace it by an amount proportional to the head of liquid, whilst a column of liquid is moved by the smaller capsule d to give directly, or by means of an indicating gauge, an indication in a convenient position of the liquid level in the tank. In the case of a gravity-feed system for a motor-car, the gauge may be connected to a tapping from the petrol supply pipe between the fuel tank and carburettor, and leads by a pipe a to an open casing containing the capsules b, d, the liquid level reading being indicated on a scale or by a gauge of the aneroid type shown in Fig. 7, attached to the tube e up which the indicating column is moved. In the case of a pressure-feed system, the casing containing the capsules is closed and the effect of the pressure in the tank on the gauge is neutralized by a pipe i in communication with the gauge-tube e and the casing. Alarms actuated electrically may be used to give warning when the level falls below a predetermined amount, e.g. by a contact disposed in conjunction with one of the capsules or a float on the liquid in pipe e may close a circuit when the level falls. More than two such capsules may be employed, the intermediate ones being used as a transmitting medium between the first and last of the series.

Abstract: 613,316. Musical drums. ANGELLIAUME, L. A. June 18, 1946, Nos. 18294 and 18295. Convention dates, Nov. 2, 1944, and May 30, 1945. [Class 88 (ii)] An arrangement for adjusting the tension of the parchment of a drum comprises means for securing the parchment to the barrel and an internal tensioning device which presses a ring- shaped member against the parchment and is adjustable by control means operable externally.. The parchment 1, Fig. 7, is held on the barrel 3 by a hoop 2 which is clamped in position by a ring member 4. This member is. split diametrically and the two parts are hinged together for fitting over the drum barrel and are then secured by a locking catch (Figs. 2-6, not shown). Axial displacement is prevented by mutual engagement of the recess 6 and projecting rim 7. The parchment is tensioned by a ring 11 supported by radial arms 13 from a frame 12 which can be moved axially by engagement of a roller 15 with a cam 16 rotated by an external control knob 19. When both parchments are adjusted in this way, one cam 16a is mounted on a rod 17 and the other 16 is mounted on a concentric sleeve 18. Each of these carries a toothed member 23, 22, Fig. 9, for engagement with corresponding teeth in an axially slidable knob 19, which is normally urged by a spring 24 into engagement with the toothed ring 23 pertaining to the upper vellum. In an alternative means for securing the vellum, the barrel 3, Fig. 12, is of reduced diameter adjacent to its rims and the parchment, secured to the hoop 2, is held in position by a circular member 4a pressed into position and retained by partial rotation so as to engage lugs 28 in apertures in further lugs 29 on the barrel 3. In each case new vellum may be fitted on spare hoops ready for immediate fitting to the drum.

Abstract: 596,069. Keyboard switches. JOHNSON, H. R. July 17, 1945, No. 18313. Convention date, July 11, 1944. [Class 38(v)] [Also in Group XL] Simultaneous operation of any two push buttons 5-10 is prevented by thin slidable cam members 77-81 engaging the ends of the push button stems 39-44. The cam members occupy a narrow slot in the switch support 19 and complete depression of any button causes the cam members to take up positions in this slot preventing the complete insertion between them of a second push buttom stem. A plate 51 retains the cam members. Springs 45-50 return a button when a subsequently pressed button frees it from a spring-biassed latching strip 22 in known manner. A silencing strip 83 reduces any sound caused by the rebound of a push button. Each push button operates a two-pole make-before-break spring pileup assembly, with cam actuation, Fig. 3. The leaf springs of the pile-up assemblies are connected to sockets 84, 85 in an insulated panel structure 86. The whole pushbutton unit is mounted on guides 88, 89 engaging guide rails 3 in a cabinet 1, from which it is removable. The invention is described in its application to an automatic telegraph printing system, wherein it precludes the simultaneous connection of two line circuits to one printing equipment.

Filed: 1921-07-07
Abstract: 186,186. Constable, A. July 7, 1921. Step-by-step conveyers. -Bolt blanks are fed through a furnace by means of a pair of toothed bars having a relative reciprocating motion, the arrangement being such that in one direction of motion one of the bars rides over the blanks held by the teeth of the other, and in the reverse direction the blanks are fed forward one step. In the construction shown the lower bar 3 is fixed while the upper one 6 is mounted in a reciprocating carrier 5, the two bars being opposite a slot in the wall of the furnace through which the blanks project. Each bar is built up of a number of toothed strips separated by distance pieces, and the two bars are so arranged that the toothed strips of one project between those of the other. From the position shown in Fig. 3, the upper bar 6 is moved to the left, pushing the blanks 12 up the inclines 11 and down to the next teeth of the bar 3. On the return stroke the blanks are held by the bar 3, while the upper bar rides over them and returns to the position of Fig. 3. The blanks are delivered to the conveying mechanism from the space between a fixed incline 21 and a slide 22, which rests on the blanks and contacts with the end of the reciprocating carrier 5. At the end of each forward stroke of the carrier a gap is left between the end of the incline 21 and the carrier 5, and a blank falls into the first tooth of the bar 3.
