Title: A building beam and method for using same in a building construction
IPC: E04B5/23
Filed: 1953-06-18
Abstract: 749,604. Prefabricated building beams. JANHUNEN, M. June 18, 1953, No. 16909/53. Class 20(4). Floors and ceilings are formed of prefabricated building beams 1 reinforced with pretensioned rods 4, the beams, placed side-by-side with their ends resting upon the walls, or supporting beams, of a building, 'being provided with a layer of concrete 6 upon their upper faces and a plate 8 secured beneath them. Additional reinforcements 7 are incorporated between the beams if it is desired to strengthen the structure, and where it is necessary to strengthen the meeting edges of the beams they are joined together by reinforcements and are concreted to be solid. To join beams 1 to a support beam 11, Fig. 6, the reinforcements 4, projecting from the edges of the beams, are placed in the mould for the support beam, after which the concrete is applied in the usual manner. The floor, Fig. 5, is formed of two layers of beams, sound attenuating material being placed between them if desired. In one form of floor construction, the'beams are laid at right angles to each other, and in another form the open faces of the beams in both layers face upwards. Walls constructed as described above may be covered with flat plates. The beams may be provided with solid covers for their open faces.

Title: Improvements in or relating to telephone paystations
IPC: H04M17/02
Filed: 1938-06-07
Abstract: 499,270. Coin - - freed telephone apparatus. TELEPHON-APPARATFABRIK E. ZWIETUSCH & CO., GES. June 7, 1938, No. 16924. Convention date, Dec. 24, 1937. [Class 27] In coin-freed telephone apparatus in which the inserted coin is held in suspense in a shoot until the receiver is replaced, whereupon the normal holding means for the coin is removed and a magnet is energized to effect the blocking of the refund shoot, the armature of the magnet is actuated momentarily and mechanically due to replacement of the receiver before the normal holding means are removed. The invention avoids the necessity for separating the normal holding means and the means blocking the refund shoot to allow sufficient time for the energization of the magnet, and is of particular application to compact table apparatus. As shown, an inserted coin passes down a shoot 1 and comes to rest against a projection 9 on a lever 4 consituting the normal holding means, and in this position raises a roller 19 to open contacts 20 shunting the dial contacts. When the receiver is replaced, an abutment 7, connected with the mechanism of the receiver-hook switch, engages an arm 34 of lever 4 which is actuated to release the coin. Before the coin is released by lever 4, however, the abutment 7 also momentarily depresses a blade spring 35 on the armature 13 of the refund magnet SM, and the armature rocks a lever 3 to block the passage of the coin. Magnet SM is thereafter energized in the usual way, and its eventual de-energization, when the connection is broken, releases the coin, if it has not been " cashed-in," and allows it to pass on to the refund shoot. In the case of a chargeable call, a magnet KM is energized. before de-energization of magnet SM. Its armature 12 rocks a third lever 5 having a projection 14 which thrusts the coin sideways through an aperture in shoot 1 into an adjacent " cashing-in " shoot. The magnets with their associated mechanism, and the receiver hook mechanism are mounted on either side of the shoot for compactness. Fraud, preventing.-A spring-actuated lever 22 projects into the coin shoot 1, and a spring- loaded element 17 projects into the side aperture in the shoot through which a coin being " cashed-in " is passed by lever 5. Both these devices permit the passage of a coin in the required direction, but prevent reverse movement if the apparatus is tilted for purposes of fraud.

Title: Apparatus for processing yarn
IPC: H05B3/00
Filed: 1966-04-19
Abstract: 1,136,746. Crimping yarns. LEESONA CORP. 19 April, 1966 [20 April, 1965], No. 17041/66. Headings D1D and D1F. In apparatus for false-twist crimping thermoplastic yarn comprising a false twist device (10, 20) Figs. I and 2 not shown, and a preceeding heating zone, a preheater device is provided between the yarn supply means and the heating zone. The preheater comprises spaced feed rolls 53, 54 driven at a speed related to the speed of delivery rollers (11 21) to control the yarn tension between the sets of rollers and heated to raise the temperature of the yarn to a value below that necessary to effect reorientation of the molecules of the yarn. With nylon the temperature of the heater zone would be 430‹F. to 480‹F. and the temperature of the preheater zone would be 270‹F. and 330‹F. Rollers 53, 54 are hollow, see Fig 4 not shown, and are mounted over blocks (43, 44) mounted on a plate 41 heated by elements 42. A twist stopper 15 is provided on the delivery side of the preheater rollers adjacent the entrance to the heating zone which contains a plate 31 heated by elements 32. The heating and preheating zones are surrounded by block insulation. Rollers 53, 54 are provided with parallel grooves to space adjacent yarns passing thereabout. The surface of the rollers is such as to allow the yarn to contract and slip thereover. In Fig. 5 not shown the preheater rollers are without grooves and a roller (160) biassed by a weighted lever engages preheater roller (154) to nip the yarn thereagainst particularly just after the yarn engages and just before the yarn leaves roller (154). In this case a twist stopper 15 may be dispensed with.

Title: New or improved process for the utilization of peat as fuel and apparatus therefor
IPC: E21C49/00
Filed: 1918-10-19
Abstract: 166,576. Klasson, R., and Kirpotschnikoff, V. Oct. 19, 1918. No Patent granted (Sealing fee not paid). Multi-stage centrifugal fans and pumps.-In a process of making peat briquettes, the peat is washed away from the walls of the peat bog or pit and collected in a deep part of such bog or pit whence it is pumped by a turbine pump constructed to act also as a crushing-machine, and delivered by piping to a drying-field whereon the peat is spread out in a thin layer to be cut into blocks by known means. The pump with its .accessories is suspended from a crane running upon rails and is connected by flexible connections to the piping so that the crane can travel along the rails and the pump can be raised or lowered without disturbing the piping; or the pump with its accessories may be suspended by means of a pulley from a block adapted to travel along a rope stretched between two supports near the sides of the peat dog or pit. A multi-stage turbine pump shown in vertical section in Fig. 5 may be employed. Each stage a consists of a guide portion 3 which is contracted upwardly and carries vanes 5 and a delivery portion 1, Fig. 5, which widens upwardly and encloses a vane-wheel 4 mounted upon a central shaft 11. The lowest stage a<1> of the pump is preferably formed with an enlarged inlet passage obtained by using a cylindrical portion 6 or a conical portion with its wider end downwards. The hub 2 of each vanewheel conforms to the internal form of its corresponding portion 3 or 1 so that the passage for the peat pulp is approximately constant throughout the pump. Roots and other hard substances in the peat are prevented from entering the pump by a vane-wheel 4<1> on the lower end of shaft 11. A blade 9 preferably having a serrated cutting edge coacting with the sharp edges of the vane-wheel 8 is secured by means of a plate 10 to the lowest portion 6 of the pump. The number of turbine stages may be reduced to the smallest necessary to effect the grinding and crushing of the peat; if this number of stages is too small to generate the necessary delivery pressure of the peat pulp, the extra pressure required can be obtained by using another pumping-apparatus. Fig. 11 shows such an apparatus. The shaft 11 carries a two-stage apparatus of the kind already described and also a centrifugal vane-wheel 14 enclosed within a casing 13. Reference has been directed by the Comptroller to Specification 1725/75 and 13391/10, [both in Class 50, Fuel, Manufacture of], and 12101/13.
Patent GB-972623-A (GB)
Title: Cigarette filters
IPC: A24D3/10
Filed: 1963-05-01
Abstract: 972,623. Batting. CELANESE CORPORATION OF AMERICA. May 1, 1963 [May 15, 1962], No. 17132/63. Heading B5B. [Also in Division D1] A controlled small quantity of a lubricant is applied substantially uniformly to a fibrous batt, which is then packed in compressed layers as in a bale or tow can from which it can be withdrawn for use in the production of cigarette filter plugs. Preferably, the batt is somewhat compressed to form a roving-like rope before the lubricant is applied, suitably in a proportion of 0.1% to 2%, especially 0.15 to 0.80%, of the dry weight of the batt. Substantial uniformity of application of lubricant is achieved by permitting the batt a free run from the point of application to the packaging point under little or no tension and of sufficient length to allow time for the lubricant to disperse through the filaments forming the batt. Specified lubricants include silicone oils, alkyl esters of dibasic acids, vegetable and animal oils, and especially light mineral oils. The batt is preferably cellulose acetate, but may also be made from ethyl cellulose, cellulose propionate, cellulose butyrate, cellulose acetate formate, cellulose acetate propionate, cellulose acetate butyrate, cellulose triacetate, polyamides, polyesters, e.g. polyethylene terephthalate, acrylonitrile polymers and copolymers, polyethylene, polypropylene, polyvinyl chloride, polyvinyl acetate, polyvinyl chloride-vinyl acetate and polyvinylidene chloride. As shown, the fibrous batt is made as in Specification 915,353, but a lubricant applicator unit 24, container 23, feed rolls 43 and inlet trumpet 44 are interposed between the forming nozzle 22 and the paper wrapping unit 46. Alternatively, lubricant may be applied to the batt W prior to its formation into the roving-like rope R. The lubricant applicator unit may comprise a spray chamber or constantly wetted wick across which the batt runs, but is preferably a multiple transfer roll system as in Fig. 2. In operation, oiler roll 30, rotated by drive means 27-28, transfers lubricant from reservoir 31 to felt-covered roll 34, which in turn transfers the lubricant to the smooth-surfaced roll 36 and hence to the rope R which is drawn through the nip of the rolls 36 and 37, fluted roll 37 being positively driven and roll 36 rotated by frictional contact with roll 37. The lubricated rope R<SP>1</SP> travels through the trough 39 to guide member 40 and rolls 41 without any externally applied tension, except for its own weight, permitting thorough and uniform penetration of lubricant throughout the batt. The amount of lubricant applied can be precisely controlled by regulating the speed of rotation of the polished oiler roll 30 by means of the drive means 27, since the rate of transfer of lubricant to the felt-covered roll 34 is a direct function of the speed of rotation of the oiler roll 30. Specification 922,698 also is referred to.

Abstract: 670,938. Regulating fluid flow. BROWN BROS. & CO., Ltd., and WATERSTON, J. R. C. Nov. 23, 1950 [July 10, 1950], No. 17163/50. Class 135. The fluid seal described in Specification 636,301 is modified by substituting for the rotating screen of fluid emerging from an annular orifice at the mouth of the cylinder, a series of jets 3 so directed relatively to the axis of the cylinder 1 that the axis of each jet has an axial, a tangential, and a radial component. The jets issue from passages 4 formed in a ring clamped to the mouth of the cylinder, the passages being orientated with respect to the axis of the cylinder so that each has an axial, a tangential, and a radial component. Fluid is supplied to the annular chamber 5 by one or more pipes leading into it tangentially or radially. After the cylinder is filled, excess fluid streams away from the centre of the region bounded by the jets and drains back to a tank from which it is continuously pumped to the jets.

IPC: C07C37/86
Filed: 1916-12-04
Abstract: 107,961. Darzens, G. A. July 11, 1916,. [Convention date]. Cresols.-The three cresols are separated from mixtures thereof by forming addition compounds of m - cresol with anhydrous sodium acetate, and of p - cresol with anhydrous oxalic acid, separating these crystalline compounds, and decomposing them by water. The process may be carried out by diluting the mixture of cresols with an anhydrous solvent (ligroin, benzene, toluene, xylenes, chloroform, chlorbenzene, hydroaromatic compounds, &c.), adding oxalic acid, separating the solid p-cresol addition product and decomposing it by steam-distillation in the presence of sufficient water, treating the residual mixture of o - and m - cresol with sodium acetate, separating the solid m - cresol addition product and decomposing it by distillation in the presence of sufficient water; the residue consists mainly of o - cresol. The order of the treatments with oxalic acid and sodium acetate may be reversed. If desired, the bulk of the ocresol may be removed by a preliminary fractional distillation in vacuo. The aqueous solutions of oxalic acid and sodium acetate mav be evaporated to recover these reagents. The m - cresol separated by the above process gives a high yield of trinitro - m - cresol on nitration. The Specification, as open to inspection under Sect. 91 (3) (a), refers to the separation of cresols by forming addition products generally. This subject-matter does not appear in the Specification as accepted.
