Filed: 1974-09-10
Abstract: 1473160 Tape recorder AMERICAN OPTICAL CORP 10 Sept 1974 [10 Sept 1973] 39417/74 Heading G5R In a slow speed tape recorder, e.g. a cassette recorder for recording physiological signals from a patient at a tape speed of <SP>1</SP>/ 16  inch per sec., a flywheel 38 for smoothing out wow and flutter is provided as a separate item which is driven by belt 26 from motor 16 and in turn drives capstan 50a via belt 42 and pulley 50b. Take up reel drive pulley 66 is driven by belt 56 from a pulley 52a which is freely rotatable on the capstan spindle and fast with a further pulley 52b driven by a belt 40 from the flywheel. In use the motor runs at 300 r.p.m., the flywheel at 130 r.p.m. and the capstan at 18 r.p.m., thus the speed stabilizing energy stored in the flywheel is very much greater than the energy stored in the capstan and its pulley.

Title: Tube corrugating apparatus and method
IPC: B21D15/06
Filed: 1972-08-24
Abstract: 1384128 Corrugating tubes ANDREW CORP 24 Aug 1972 [27 Sept 1971] 39497/72 Heading B3E  Apparatus for annular corrugation of tubing comprises a guide having a circular passage for the tube, means for advancing the tube through the passage, an endless series of corrugating elements coupled together and mounted on the guide for cycling into and out of a region of the passage, such cycling being effected by advance of the tube, the region of the passage forming a tight fit for the tube, and means for rotating the guide about the tube. In the apparatus described, Fig. 2, the tube 10 to be corrugated is fed by grippers 40 on an endless drive 36 through a corrugating head 28 rotated in fixed bearing blocks 55, 56 by drive 57. The head, Fig. 4, comprises a guide bushing 64 flared at its entry opening 77, arid a wheel 69 freely pivoted on an axle 70 fixed to the bushing-so that the wheel is offset in the direction of rotation of the head from a diametral plane through the tube, see Fig. 3 (not shown). Corrugating elements 75 consisting of short lengths of carbide steel rod are silver soldered into grooves in the wheel and engage the tube to form the corrugations as the head rotates, the wheel being rotated about axle 70 by passage of the tube through-the head, the corrugation pitch thus being determined solely by the spacing of elements 75. The head may have a number of such wheels equiangularly spaced about the tube, in particular two wheels offset in opposite directions from the diametral plane. In the case of a hollow tube, the wheel diameter may be such that when one element is at its position of maximum penetration, its successor is at no more than 75% penetration, preferably 25% to 50%. In the case of a foamdielectric filled tube, this figure may be substantially greater than 50%, so that three or more succeeding grooves have been initiated when an element is at maximum penetration. In another embodiment, Fig. 7 (not shown), the corrugating elements are mounted on an endless chain or belt system in place of wheel 69.

Abstract: 945,225. Electric motors. ALLMANNA SVENSKA ELEKTRISKA A.B. Nov. 8, 1961 [Nov. 9, 1960], No. 39937/61. Heading H2A. In an electric motor comprising a rotor and a stator separated by an air gap, a polyphase winding is arranged on either the stator or rotor one of which is provided with salient poles while helical grooves facing each other across the air gap and running parallel to each other are formed in both the rotor and stator cores. Preferably the stator is provided with a three phase winding and the rotor with the salient poles 3. Upon the energization of the stator windings with direct current the rotor, for example arranged vertically, is locked in position with respect to the stator. When the energization is changed to a low-frequency three-phase alternating current the stator rotor rotates in synchronism therewith screwing into or out of the stator a predetermined amount with each rotation. Hence by application of a predetermined number of cycles of the alternating current the rotor can be moved axially a predetermined distance, for example to adjust the position of the control rods in a nuclear reactor. It is stated that alternatively the rotor may surround the stator.

Abstract: 852,123. Pipe making machines. ALESSANDRO CALZONI S.p.A. Dec. 27, 1957 [Feb. 1, 1957], No. 40219/57. Class 99(2). In a machine for the continuous manufacture of pipes of fibrous material e.g. asbestos-cement, two pipe-making machines A, B are arranged in tandem, and a continuous conveyer intermittently advanced and carrying mandrels 3 to the machines A, B comprises two side chains each mounting a series of saddles 2 at intervals equal to one third of the distance between the machines. Guides for the chains consist of sections 13 in fixed positions and movable sections 10, 14 corresponding to the machines A, B, and these are means for feeding mandrels on to the saddles, means for controlling the intermittent advance of the chains and the movement of the sections 10, 14 of the chain guides, and the feeding of the mandrels in an interdependant manner according to a predetermined sequence. As shown, the chains, which carry the V-shaped saddles 2 and are driven by a motor 6 and wheels 4, 7, pass over guide sections 8 adjustable in height by piston devices 9, sections 10 and 14 movable in height by piston devices 20, 21 and fixed sections 13 provided with chain-locking devices 13<SP>1</SP>. Two fixed saddles 15, 16 corresponding with those on the section 8 are provided. For transferring the mandrels from guides 23, having stops 24, to the saddles 2, there is provided pairs of arms 25, 30 having dowels 26, 31 for engagement with the ends of the mandrels, and, respectively, rotatable about shafts 28, 33 by motors 27, 32 ; the arms are movable laterally on the shafts by piston devices 29, 34. Motor-driven endless tracks feed the mandrels along the guides 23. In operation, the arms 25 are rotated and caused to move towards each other along the shaft 28 until the dowels 26 thereof engage in the ends of the mandrel 3 abutting the stops 24, again rotated to transfer the mandrel to fixed saddles 35, and then moved apart to disengage the dowels from the mandrel. The arms 30 are operated in a similar manner to engage the next mandrel on the guides 23 and the mandrel on the saddles 35 and to transfer these mandrels to the fixed saddles 15, 16 from which the mandrels are removed by upward movement of the guide section 8. As shown, the machine A is forming a pipe 3<SP>1</SP>, the guide section 14 being in the lower position thereof, and the machine B is in readiness to form a pipe, while between the machines the saddles 2 of guide section 13 carry a pipe prepared by the machine B and a mandrel for reception in machine A. When the pipe in the machine A has reached the desired thickness, and the machine B and guide section 10 have been lowered to allow the making of a pipe, the machine A and guide section 14 are raised and the conveyer chains translated whereby the formed pipes 3<SP>1</SP>, 311 are removed from the machine and another mandrel is received in the machine A, two further mandrels being placed on the saddles 15, 16.

Abstract: 1,153,034. Gas turbine &c. combustion apparatus. ROLLS-ROYCE Ltd. Dec.20, 1966 [Sept.21, 1965], No.40221/65. Heading F1L. A duct 12 contains a V-cross section flame stabilizing gutter 11, wherein the downstream edge 18 of each limb of the V has small projections 19 and each arm 16 of the gutter extends from a centre part 15 in a downstream direction obliquely to the general direction of airflow 20. The duct 12 may be a rectangular ram jet duct or the annular by-pass duct of a gas turbine engine, in the latter case the gutter 11 being curved to follow the curvature of the duct. A pipe 25 on centre part 15 supplies fuel to branch pipes 28 each extending along the full length of an arm 16 on the downstream side thereof and communicating through holes 29 with the upstream side. Thus, fuel leaving the holes 29 is driven by the airflow 20 to the edges 18 of the arm where part is drawn into vortices 23 set up by the arm and the remainder is drawn into the wake 21. Igniters 24 on the centre part 15 ignite the adjacent combustible mixture to form a pilot flame which is drawn by the spiral motion of the vortices 23 outwards along the arms to ignite the fuel supplied through the holes 29 remote from the part 15. The projections 19 have the effect of causing burning gas from the vortices to be drawn into the wake 21, as shown at 27. The end 17 of each arm 16 is substantially parallel to the adjacent duct wall 14 so that the flame is not directed against the wall, and is formed such that the limbs of the V are inclined at a greater angle, Fig. 4 (not shown), than at part 15. If the mixture in the pilot zone adjacent part 15 is made sufficiently fuel-rich, fuelling along the length of the arms 16 may be dispensed with. Fuel may alternatively or additionally be injected into the wake 21 from injectors 30 mounted on the duct sidewalls 13, or, in a further modification, may be injected upstream of the gutter.

A catalyst support may be prepared by precipitating an alumina gel at a temperature below 50 C. by the neutralization, to a constant pH up to 11 and preferably between 8.5 and 9.5 of an aqueous solution of an alkali metal aluminate or aluminium salt, so that the resulting suspension contains between 40 and 80 grams per litre of alumina (Al 2 O 3 ).   The   gel is filtered off, washed, dried at about 110 C., and activated by heating to 350 to 500 C. for 1 to 4 hours. The process may be carried out continuously by feeding an aluminate solution and a precipitating solution into the lower part of a precipitation vessel, fitted with a stirring device; the alumina suspension is discharged from the upper part of the vessel. The rates of flow are so regulated that the suspension is discharged after its constituents have been in the precipitation vessel for 10 to 30 minutes. The product so produced is an activated alumina which includes micropores having a diameter of less than 0.1 micron, the volume of which amounts to 35 to 55 c.c. per 100 grams, and macropores having a diameter between 0.1 and 10 microns, the volume of which is 15 to 65 c.c. per 100 grams.

Abstract: 1536958 Load carrying vehicle body B BUNGER 1 Oct 1976 [2 Oct 1975] 40905/76 Heading B7B A discharge closure formed by or including an end or side wall of the body is upwardly and outwardly inclined and is pivoted to the remainder of the body in such a way that its own weight tends to keep it closed. As illustrated in Fig. 5, the body has a rear tipping axis 5, and the rear end wall is connected by arms 20 to inboard hinge points 3. In the alternative construction illustrated in Fig. 3 (which shows an end view of the body), the body is divided diagonally into two. For unloading purposes, the upper part, including side wall 2<1>, is upwardly pivoted about an axis located at the top of the diagonal. Thereafter, the then open body is tipped about an axis at the lower end of the diagonal. In a further construction, Fig. 4 (not shown), a side wall is connected by arms to an inboard pivot point. The arrangement increases the tendency of the closure to remain closed since the load exerts a downward component of force on the closure.

Abstract: 1,204,128. Foamed plastics laminate. SCHOLL MFG. CO. Ltd. 7 Sept., 1967, No. 41023/67. Addition to 896,623. Heading B5N. A foam material is prepared or produced by a process according to any of claims 1 to 15 of Specification 896,623 and comprises a substantially open-celled polyurethane foam impregnated with a flexible, thermoplastic vinyl resin, and a covering layer of fabric or thermoplastic sheet material contiguous with and bonded to at least a portion of a surface of the impregnated foam. When the covering layer is of fabric, which may be of woven or knit natural or synthetic fibres such as cotton or nylon, and which may include water- or stain-repellants, the covering layer is bonded to the impregnated foam by rendering the vinyl resin tacky using heat, e.g. infra-red heaters, flame jets, hot air, or dielectric heating, and/or a solvent, and applying the covering layer to the foam under pressure. The heat may be applied simultaneously with the pressure by using heated rolls or dies. When the covering layer is a thermoplastic sheet, e.g. polyvinyl chloride or acetate, it may be applied to the foam by the above method, or may be applied as an incompletely set still tacky film to the untackified foam and pressed thereagainst. In another method a fabric covering layer is applied to the foam while the impregnant is still tacky. The covering layer may be bonded to the foam only at spaced areas, and may be bonded to one or both surfaces of the foam. Auxiliary adhesives such as vinyls, acrylic compounds, or polyurethanes may be used to assist the bonding. The foam may be at least 75% open-celled. The impregnant may be P.V.C. or polyvinyl acetate applied as a solution, emulsion, or plastisol, and may also include plasticizers, e.g. phthalates. The cushioning material may be provided with a contoured surface by embossing whilst the vinyl resin is tacky using heated dies or embossing rolls. The embossing may take place during bonding of the layers, and the embossed assembly may be cooled under pressure. In the example, a woven cotton fabric is roller-coated with a vinyl chloride copolymer emulsion, heated, and laminated to an impregnated polyether polyurethane foam. The impregnant is a vinyl chloride/vinyl acetate resin and is applied to the foam by roller coating and then reducing the ambient pressure to draw the resin into the foam. The foam and fabric are heated and bonded together using a vinyl adhesive under pressure.
