Title: Improvements relating to the production and utilisation of fibrous material
IPC: C08L7/00
Filed: 1939-05-15
Abstract: 532,310. Paper containing rubber &c. CASSATT, E. B. May 15, 1939, No. 14475. [Class 96] [Also in Groups V and IX] A graded rubberized fibrous material is made by disintegrating waste fibrous material in one or more stages by means of rotary beaters operating in a current of air to prevent overheating and burning of the waste, drawing the disintegrated waste through a sieve and reducing it by attenuation in a gaseous current to an evenly opened loose graded condition and then mixing a desired grade of the material with rubber dough containing a solvent to form a substantially homogenous mass which may be made into sheet form and allowed to set. The sheets may be laminated with other sheet material and a light substance such as cork may be added for the manufacture of lifebelts, insoles &c. A sponge-like texture may also be obtained by aeration. A small amount of water, sulphur and zinc oxide may be added to the rubber dough. Specification 532,105, [Group V], is referred to.
Patent GB-384905-A (GB)
Title: Improvements relating to wire-stapling machines
IPC: B25C5/04
Filed: 1932-05-21
Abstract: 384,905. Stapling. BATES MANUFACTURING CO., 18, Central Avenue, West Orange, New Jersey, U.S.A. May 21, 1932, No. 14518. Convention date, June 25, 1931. [Class 89 (iii).] In a stapling-machine of the kind in which staple-lengths of wire are drawn intermittently from a reel by wire-feeding devices, the reel is mounted both for rotary movement about its axis and for bodily movement in the direction of the pull exerted on the wire by the feeding devices, such bodily movement normally being opposed yieldingly. As shown, a hand stapling tool comprises side-plates 5 pivoted to a base 1, and an operating lever 28. The latter operates the usual shaping and driving members 22, and also a lever 24 which controls a wirefeeding slide 18 provided with a feed dog C<1>. The wire reel S is removably mounted on the tool by means of a bracket 47, which is fixed to the axle 33 of the reel and is provided with pivot lugs 49 adapted to engage in L-shaped slots 50 formed in extensions 17 of the plates 5. The reel is thus free to rotate about its axle 33, and to move bodily about the pivots 49 when a feeding-pull is imparted to the wire W. This bodily movement is opposed by a spring 35, which is fixed to the bracket 47 and engages a fixed pin 14. The spring 35 is integral with a spring 34 which carries a yielding facing 341 adapted to press on the wire on the reel and so brake the rotation of the reel. The latter comprises a hub 37, Fig. 4, which has reduced end portions 38 fixed to side discs 39. These are cut away at the centre, and formed with dished spiders 41 which are rotatable on the axle 33 of the reel. The axle has reduced end portions 46 which are fixed to the bracket 47.

Title: Improvements in or relating to a process and apparatus for making junctions in pipes of thermoplastic material
IPC: B29D23/00
Filed: 1959-04-28
Abstract: 849,620. Moulding branched thermoplastic pipes. FARBWERKE HOECHST AKTIENGESELLSCHAFT VORM. MEISTER, LUCIUS & BRUNING. April 28, 1959 [April 30, 1958], No. 14550/59. Class 87(2). A method of moulding junctions in thermoplastic pipes comprises placing a length of pipe 1, having an aperture at the site of the junction, in a mould 2, locating cores 3, 3a in the pipe 1 to support it in the region of the junction, plasticizing the pipe in the region of the junction but not at its ends and of applying pressure to at least one pipe end to force the plasticized part of the pipe into the mould cavity 14 to form the junction. The pipe may be plasticized by electrically generated heat or, as in Fig. 1, by the passage of hot air through the mould. After heating the pressure may be applied by screw means 18, 20 which longitudinally displace the pipe 1 and sleeves 24 to mould the junction. Fig. 1 shows the pipe before and after moulding. If a flange 12 is to be moulded on the pipe a loose collar 13 may be inserted in the mould for subsequent coupling of the junction in a pipe line. Separate pipes may be inserted in the mould to subsequently fuse into the article and pressure may be applied from more than one pipe end. Fig. 3 (not shown), shows the mould extended at the branch to encompass the pressure applying means.

Title: Improvements in the method of joining the abutting ends of rails for railway lines
IPC: E01B21/04
Filed: 1923-06-04
Abstract: 222,910. Seguin, G. June 4, 1923. Uniting by fusion; thermoaluminic processes. - In joining railway rails by pouring molten metal in a cavity between the abutting rail-ends and in a sleevelike device constituted by two plates embracing the major portion of the abutting ends, the plates have a cross-section corresponding closely to the contours of the rails and the rail-webs are provided with a vertical slot which merges into the base-flanges. In new rails, the base-flanges are bevelled at b and the abutting webs provided with a slot r about 15 mm. wide. To form the joint the base-flanges are first welded together, the plate a is placed in position and welded to the edges of the slot r which is filled with molten metal, the opposite plate a is then added so as to adhere to the hot metal in the slot, both plates are welded along their peripheries, and finally molten metal is poured into the recesses c. In the case of worn rails which have become chamfered at their ends, the slot r is carried completely through the baseflanges, this latter space being filled with metal through slots e, Fig. 5, formed in the plates a. The welding operations may be performed by a carbon arc, or by a metallic welding-electrode, or gas or thermo-aluminic welding methods may be adopted.
Patent GB-864968-A (GB)
Title: Improvements in key-operable tumbler locks
IPC: E05B27/04
Filed: 1959-04-30
Abstract: 864,968. Key locks. GENERAL MOTORS CORPORATION. April 30, 1959 [May 23, 1958], No. 14757/59. Class 44. A key operable tumbler lock has a housing 12, a cylinder 10 which is rotatable in the housing, and which contains a keyway 36, the tumbers 16 and a side bar lock member 42 withdrawable by a spring force to enter aligned tumbler notches 32 and advanceable in the opposite direction into locking position, a spring arm being provided which, when the cylinder is in locking position, overcomes the withdrawal spring force and advances the side bar member but which when the cylinder is turned by the key towards unlocked position is relieved sufficiently for the withdrawal spring force to withdraw the side bar member. In the construction shown in Fig. 4, the withdrawal spring force is provided by coil springs 52 and a blade spring 60 has a pair of spring arms 64, 66 (only 64 of which is shown) to overcome the withdrawal spring force and advance the side bar member. The springs 52 are trapped between seats 48 on the side bar member and a retaining plate 54 which is secured to the cylinder 10. The base 62 of spring 60 is mounted within a cylinder recess 58 with a portion 67 extending beneath a projection 68. A spring tang 70 co-operates with a projection 72 on cylinder 10 to maintain the portion 67 beneath the projection 68. The two arms 64, 66 engage seats 57 on the side bar member 42 and normally these overcome the force of the springs 52 so as to cause the outer portion 73 of the member 42 to project within a longitudinally extending notch 74 formed within the housing 12. Rotation of the cylinder 10 is thereby prevented except for a limited extent. When a key is inserted within the keyway 36 the tumblers 16 are moved against the pressure of their biasing spring 22 so that the notches become aligned; turning the key then rotates the cylinder 10 to a small extent owing to the greater width of the housing notch 74 than the outer portion 73 of the side bar member and this initial rotation causes protuberances 76 and 78 (not shown) on the spring 60 to be cammed out of a groove 80 in the housing. This camming action causes the arms 64, 66 of the spring to be moved inwardly and away from the seats 57 of the side bar member thus relieving the spring force of the arms 64, 66 and permitting springs 52 to withdraw member 42 so that its tongue 46 projects into the tumbler notches 32. The end portion 73 of the side bar member is thus withdrawn from the notch 74 and full rotation of the cylinder 10 is then possible. In a modification, the spring 60 is made to serve as a retainer for the tumbler springs 22 thereby eliminating the retaining plate 30 necessary with the first construction. In a further modification, the springs 52 are omitted and instead the spring 60 has two pairs of arms to provide both the withdrawal spring force and the advance spring force.

Title: Outboard propeller drive
IPC: B63H20/22
Filed: 1930-05-14
Abstract: 345,150. Detachable propelling installations. SCHALK, J. R., Rhinebeck, New York, U.S.A. May 14,1930, No. 14822. [Class 114.] An outboard propeller installation with depending shaft which can be tilted to avoid obstructions and turned to effect steering is characterized by the provision at the top and bottom gear-casings of sets of bevel wheels which are connected by intermediate idler annular gear-wheels. The depth of immersion of the propeller may also be regulated. The upper casing comprises a housing formed of two concentric parts 18, 20 adapted to swivel one on the other and having trunnions 16, 17 mounted in bearings 15 on the supporting frame. The part 18 is formed with a depending tubular portion 19 and the part 20 is formed with bearing bosses 21 and 29 at right angles to its axis. From the part 19 is supported a tubular casing 25 for the transmission shaft 60 and it in turn supports the casing 23 of the propeller gears. This casing 23 carries a skeg 26 which when it strikes the water is adapted to swing the outboard installation on the trunnions 16, 17. When the installation is locked by a pin 32 this has to be sheared before tilting can take place. The casing 25 is adjustable in the tube 19 for regulating the depth of immersion and the transmission shaft 60 is accordingly formed in two parts with the sliding stepped connecting faces 61. Transmission in the upper gear box from the engine shaft 50 is by means of a bevel 43 acting on an idler bevel 40 and thence on a bevel 53. The gearing in the propeller box is constituted by the bevel 70, idler 65 and bevel 67. In one form the driving-engine shaft carries two free bevels which mesh with opposite diameters of the main bevel 40 and between them is a splined sliding claw-coupling for engaging one or other. This clutch member in the middle position provides a neutral position. The yoke 100 is employed for rotating the tube 25, thus providing for steering.

Abstract: 739,546. Electrically heated spatula. IKSE, J. I. May 20, 1954, No. 14843/54. Class 39 (3). [Also in Group VI] An electrically-heated spatula has a blade formed with parallel ridges 5 of V-shaped crosssection, the apex of the V being directed outwards. Owing to the relatively small area of contact between the blade and wax at the apex of each ridge, the bulk of the wax does not become softened to any appreciable depth. A transverse flange 6 is provided at the rear of the blade so that, when the spatula is not in use, it may be placed on a wire support 11 and any adherent wax will melt and run towards the flange and then drip off the end thereof into a suitable receptacle.

Patent GB-587041-A (GB)
Title: Hearth bottoms
IPC: F27B3/12
Filed: 1944-08-08
Abstract: The lining of a basic hearth is prepared or patched by spreading a relatively thick layer consisting of 60-90 per cent of ground magnesite and 40-10 per cent. of ground chrome ore and heating to a temperature above 2600 DEG F. to form a sintered crust sufficiently strong to support the furnace charge; a surface layer of ground dead-burned dolomite or magnesite may be added before heating.  The magnesite is prepared by burning natural magnesite, brucite, or dolomite or a mixture thereof, and preferably contains 65-70 per cent. of magnesia.  It is ground to pass a one-quarter inch screen with not more than 50 per cent passing a 20- mesh screen and 10 per cent. passing a 100- mesh screen.  The chrome ore has a low iron and high alumina content and is ground to pass a 1/8 -inch mesh, with 80 per cent. passing a 20- mesh, and 40 per cent. passing a 100- mesh screen.  The raw materials are mixed dry.  The mixture is shovelled into the furnace and smoothed down, and the layer of about 1 inch thick of dolomite or magnesia is then added.  The furnace is heated to above 2600 DEG F. for an hour and can then be used, subsequent heating causing the whole of the lining or patch to sinter into a monolithic mass.

Filed: 1973-03-29
Abstract: 1413893 Protecting rectifiers; protective arrangements N MIRONOFF 29 March 1973 [30 March 1972] 15144/73 Headings H2F H2K [Also in Division B3] The current across a spark erosion machining gap is reduced when the mean machining voltage Udm falls below a predetermined value. A supply source in the form of a transformer 1 is connected to a rectifier comprising diodes 2 and thyristors 3 having their trigger electrodes connected to transistors 6, Zener diodes 9 and potentiometers 8. When the machining voltage Udm falls below a certain value, determined to one of the potentiometers 8, the transistor 6 connected to the highest voltage Zener diode 9 is rendered non-conductive causing the corresponding thyristor 3 to be cut off and the current to be reduced. If the voltage across the gap falls further, another transistor 6 connected to a lower voltage Zener diode 9 is cut off which causes a second thyristor 3 to be cut off so that the current is further decreased. Should normal conditions in the machining gap be restored, the transistors 6 are switched back on again and the current is restored to the normal value. The supply current is completely cut off if the third thyristor 3 is switched off by a further reduction in the machining voltage. The voltage Vdm may be subsequently restored by a low intensity pulsating current delivered via a diode 10.

[Class 83 (iv)] Gap gauges that have become unserviceable through wear have the metal between the gaps upset to permit the gauges to be reground to the original size. The gauges are heated whilst expansion is prevented but are allowed to contract on cooling. The gauge 84 is clamped between fixed and movable electrodes 34. The fixed electrode is bolted to a base 36 above a welding- type transformer with interposed insulation 38 and is backed up by a bracket 40 having insulation 42. The movable electrode slides on lugs 22 under the control of a screw 24 anchored to the electrode at 56. The gauging jaws are then clamped between copper plates 52 the upper plates being carried by L-shaped members 46 controlled by screws 48 in conjunction with abutments 62. The screw 48 for the movable electrode acts through a bolt 66 headed at 68 so that clamping the plates also clamps the electrode to the base. Perforations 70 through the electrode jaws are connected in series by pipes with expansion heads for cooling by circulated water to prevent the temper of the gauge jaws from being drawn. During heating the expansion of the gauge is prevented and the metal is upset. When this has occurred the clamps are loosened and the gauge permitted to contract on cooling which may be hastened by quenching. A machine having a similar arrangement of clamps but with flame heating instead of electric may be employed.
