Patent FI-970857-A (FI)
Inventor: WEID HELMUT
IPC: A01D34/73
Filed: 1997-02-28
Abstract: A thread cutter driven by an electric motor has a guiding stem (16) linked by a horizontal swivelling joint (18) to the thread cutter housing. A pedal trigger (46) allows locking means (42, 44) that determine the angular position of the stem in relation to the housing and that are designed as a toothed ring or tooth segment to be uncoupled. A spring (52) presses the pedal trigger into the coupling position in which the locking teeth of the locking means engage each other. When the foot rest is pressed down, the thread cutter remains in its stable support position, in which it rests on its roller (10) and on a bow that extends forwards and acts as a spacer and a skid (12). This prevents the apparatus from toppling over backwards when the foot rest is actuated, so that the stem may be adjusted without the need for additionally retaining the apparatus.

Title: Improvements in or relating to permanent magnet motors
IPC: H02K25/00
Filed: 1941-01-31
Abstract: 547,668. Direct current motors. HITCHCOCK, S. I. Jan. 31, 1941, Nos. 1306 and 15231. [Class 35] The motor has moving and stationary magnet systems, one of which comprises one or more permanent magnets having a number of polepieces, while the other comprises one or more electrically energized magnets having a number of pole-pieces, succeeding poles of each system in the path of rotation being of like polarity, and a cam-operated contact-breaker in the circuit of the energized magnets periodically energizes them, the relative position of the cam and contact breaker being adjustable to control the speed and direction of rotation. In the form described, the cylindrical permanent magnet 6, Fig. 1, is assembled on a non-magnetic rotatable shaft 5 with two laminated pole-pieces 7 having each four polar projections 11 opposite stator poles 12 carrying field coils 14 joined in series. The shaft 5 carries a cam 15, Fig. 4, actuating a rocking arm 16 pressed against it by a spring 25. Each end of the arm carries two contacts 19 facing four fixed spring-loaded contacts 20. The whole interrupter mechanism may be moved relatively to the rotor by handle 33 engaging a toothed rack 34, so that the speed of the motor may be regulated or reversed. The field coils are connected through the contacts to a source of direct-current so as to give either an attraction or a repulsion drive to the pole-pieces or a combination of the two. In the first two cases the second pair of contacts 20 is not required and may be used for additional windings utilizing or quenching the induced back voltage or additional contacts may be used for this purpose. The permanent magnet 6 is preferably subjected to an axial magnetic field during annealing so as to effect axial orientation of the molecules. The cylinder may be replaced by a number of bar or horse-shoe magnets clamped between the pole-pieces, with or without moulded cylindrical housing, Figs. 6 and 7 (not shown). A number of magnets and pole-pieces may be assembled alternately on the same shaft. The casing 1 may be of magnetic material forming the yoke for the stator poles 12, or it may be of moulded synthetic resin, when the poles 12 must be joined by independent yokes.

Title: Reciprocating engine with exhaust steam turbine
IPC: F01K7/02
Filed: 1929-01-14
Abstract: 323,383. Williams, W. P., (Wach, H.). Jan. 14, 1929. Force-feed lubricating. - In a steam power plant consisting of a reversing reciprocating engine and an exhaust steam turbine coupled to the same working shaft through gearing and a hydraulic coupling which is filled for forward running only, control of the lubrication and the supply of liquid to the coupling and steam to the turbine are effected by a fluid pressure system. The reciprocating engine a is connected to the turbine b by gearing c and a fluid coupling d. An oil pump g transfers oil from the sumps of the gear drives c to a supply tank k whence it passes to a pump which delivers to the pipe l through a 'pressure-regulating valve m having a bye-pass t back to the supply tank. Oil passes by way of valves n and o respectively to the lubricating system by pipe u, and through a control valve p to a hydraulic coupling d and a cylinder r for the operation of a steam valve e. To reverse the plant the valve p is closed, the oil pressure fails in cylinder r and the valve e is moved to lead the exhaust steam from engine a to the condenser f and at the same time the coupling d empties. When the valve p is opened the coupling fills and subsequently as the oil pressure builds up in the cylinder r the valve e is moved over to lead the steam to the turbine through a regulating valve q. In an alternative construction a throttle valve causes the oil pressure in cylinder r to open valve e a little and run-up the turbine before the coupling is filled. An emergency regulator z causes the valve e to close if the turbine reaches a dangerous speed. The stop valve s may be arranged to close if the oil pressure in the pipe l fails. The automatic valve o maintains the oil pressure in the pipe l above a predetermined value during the filling of the coupling d and the reducing valve n maintains constant the pressure of the oil passing to the lubricating points. Valves o and n may be replaced by constrictions in the pipes.

Title: Improvements in methods of and apparatus for drawing glass tubing
IPC: C03B17/04
Filed: 1941-01-31
Abstract: 543,172. Making glass tubing. BRITISH THOMSON-HOUSTON CO., Ltd. (Ferguson, J.). Jan. 31, 1941, No. 1322. [Class 56] A method of making glass tubing consists in blowing glass vertically downwards from a tube-shaping orifice in a furnace, supporting the weight of the tubing so formed in order that it may move downwards at a predetermined speed, and passing an electric current between the flowing glass and the walls of the orifice to minimize the cooling of the skin of the glass. A furnace 11, Fig. 1, is provided with a discharge opening 15 having its lower end in contact with an orifice block 19. This block comprises an outer cylindrical shell 21, Fig. 2, and an inner cylindrical co-axial shell 22 connected at their upper ends by ribs 26 in which passages 27, 28 are formed. The molten glass flows past the ribs and through the space 23 between the shells, and air is admitted to the bore of the tubing through the passages 27, 28 and the chamber 24 within the shell 22. The block is of electrically-conductive heatresisting material, such as graphite, and electricity is passed between a terminal attached to the block and an electrode in the furnace. The heating-effect of the current prevents surface chilling of the flowing glass and provides a means by which the rate of flow of the glass through the block can be controlled. The flowing stream of glass forms into a tube which attains the required dimensions at the point 35 where the glass has set. The setting of the glass may be hastened by surrounding it with a cylindrical chamber 36 provided with nozzles 37 from which air jets are directed in to the glass. The downwardlymoving tube is supported, and its rate of movement is regulated by a conveyer composed of two endless chains 52 passing around sprockets 51 carried by pairs of parallel links 45. The chains are pressed into contact with the tube by gravity, the pressure being adjusted by a spring 56. The chains are driven in unison with one another by an electric motor at a pre-determined speed such that they frictionally support the weight of the tubing while permitting it to move downwards at the correct speed for drawing; Beneath the conveyer is a cutting-device composed of two cutter arms 71 carried by screws 69 mounted in a cylindrical casing 68. This casing is rotated periodically in alternate directions by the drive of the conveyer chains, the direction of rotation being reversed by clutches operated by electromagnets. The screws 69 are rotated by a stationary gear 76 so that the cutter is alternately moved upwards and downwards. The gearing is so arranged that the cutters move downwards in contact with, and at the same speed as, the tubing. During this movement, the cutters score or sever the tube. When the rotation of the casing 68 is reversed, the cutters are moved out of contact with the glass and move upwards again to the upper end of the casing. Specification 319,361, [Class 56], is referred to.
Patent GB-1302977-A (GB)
IPC: H01F5/04
Filed: 1971-01-09
Abstract: 1302977 Inductors STANDARD INTERNATIONAL CORP 9 Jan 1971 [13 Jan 1970] 1327/71 Heading HIT A coil comprises a tubular former 12 whose outer surface contains a helical groove which receives a wire winding 10. One end of the former is in the form of a mounting surface 28, on which three mounting pods 34 are formed for the purpose of engaging the surface of a circuit board. Leads 16, 18 formed integrally with the winding extend outwardly from the mounting surface each having a crimp or knee 21 formed in them such that when the leads 16, 18 are inserted in holes in a circuit board, the apices 21 of the knees pass slightly beyond the lower surface of the board resulting in the mounting pods 34 being brought into firm engagement with the top surface of the board (Fig. 5, not shown). This arrangement allows the coil to be held in a fixed position on the circuit board prior to soldering the leads to conductors on the board. Two ribs 24, 26 formed integrally with the former enclose portions 17 19 of the leads holding the extended portions 16, 18 in a fixed position relative to the former; the ribs also serve to hold the windings of the coil immovably on the former. One rib may be longer than the other for the purpose of polarity indication or a tab 30 may be proprovided for this purpose. The former may have a series of axial ribs 32 extending along its inside surface which are of sufficiently soft plastics material that a screw threaded tuning slug 33 (Fig. 4, not shown) such as a moulded ferrite, can be screwed into the tubular former, forming complementary threads on the ribs. The coils may be formed by moulding the former around a preformed winding and may consist of more than one winding.
