Title: Improvements in temperature indicating means
IPC: G01K5/62
Filed: 1929-07-23
Abstract: 336,683. Johnson, J. Y., (Safe-T-Stat Co.). July 23, 1929. Thermometers.-Temperature-indicating apparatus particularly intended to be used in connection with the cooling system of an internal-combustion engine comprises means whereby an electric resistance is caused to vary with changes of temperature and an instrument of the galvanometer type for measuring this resistance, the pivoted indicator of the galvanometer being influenced by two electromagnets both excited by the same source of E.M.F., one electromagnet receiving a constant current and the, other a current depending on the value of the resistance to be measured. In the form shown the temperature-sensitive element comprises a metallic container 25 adapted to be screwed into the cylinder head &c. and having its lower end closed by a plug 24 to which are secured the lower end of a number of bimetallic strips 23. Secured to the upper part of the container 25 is a cap 26 of insulating material provided with internally-threaded bushings 27 adjustably carrying contact pins 28 which extend into proximity with the free upper ends of the strips 23, the pins 28 being so adjusted that as the temperature rises the strips successively make contact with the corresponding pins. A coil of resistance wire 29 is connected at one end to one of the bushings 27, at its other end to the next adjacent bushing which is electrically connected to a bushing 30, and at points along its length to the remaining bushing. A metal cover 31 passing over the cap 26 carries a terminal clip 34 secured thereto by a screw 32 passing into the bushing 30 so that the clip is connected to one end of the coil 29. The container 25 makes connection through the engine cylinder &c. with one terminal of the car battery the other terminal of which'is in connection with one end of the coil 29 so that as the strips 23 close successively on to the contacts 28, successive sections of the resistance 29 are shortcircuited. The indicator, Fig. 1<a>,, comprises a galvanometer &c., the pivoted member 42 of which, carrying the pointer 41, is influenced by two electromagnets 44, 45, comprising windings 46, 51 energized by current from the car battery 48. The winding 51 receives a substantially constant current and the winding 46 is in series with the coil 29 so that the current passing through it increases in steps as the successive sections of the coil become short-circuited, and the pointer 41 is thus caused to move in steps across the scale 40. In another form an electric resistance thermometer giving a continuous indication is used as the heat-sensitive element. This thermometric resistance may be arranged in series with another resistance adapted to be shortcircuited at a predetermined temperature by a bimetallic member so that the resulting sudden change in the reading of the pointer is a warning of the approach of a dangerously high temperature.

Title: Improvements in or relating to coding and decoding machines
IPC: G09C3/00
Filed: 1937-08-20
Abstract: 489,321. Ciphering - apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 20, 1937, No. 22886. Convention date, Aug. 28,1936. [Class 146 (ii)] Ciphering and deciphering apparatus comprises a primary and a secondary machine connected by an interposed circuit-changing mechanism which is movable under the control of a perforated member. The circuit-changing mechanism comprises a number of drums 6 each formed by a fixed insulating disc carrying brushes 7 contacting with conducting-segments in an insulating-ring rotatable with a shaft 12, the segments being connected to slip rings engaged by brushes 8. On depression of a key 1 in the primary machine T1 a circuit is closed from the battery 30 through the normally-closed contacts 31, contact 2 and depressed key 1, drums 6, normally-closed contacts 34, and solenoid 3 of a key in the secondary machine T2. Depression of a key in the primary machine also closes common contacts 4 to energize a magnet 45, the armature 46 of which causes the rotation of a pin-wheel 51 to feed forward a tape 44 having rows of arbitrarily-arranged perforations. The perforations are engaged by fingers on the ends of switches 43, so that, at each position of the tape, one or more of the switches is closed to connect the battery 40 to magnets 13 controlling the rotation of the shafts 12. Decoding can be effected in the same way if the connections in the drums are reciprocally arranged and provided the parts are restored to original position. Alternatively, after the parts have been restored to original position, and after switch 60 has been closed, decoding can be effected by operation of the secondary machine, the closing of switch 60 causing the energization of magnets 32, 35 to open contacts 31, 34 and to close contacts 37, 36. To restore the parts to original position, switches 62, 63 are closed. Closing of switch 62 connects the battery 64 [through normally closed switches 24, 67 to magnets 13a which also control the rotation of the shafts 12. The shafts 12 are thus rotated until an arm 27 thereon contacts with a fixed conducting-segment 26, when the battery 65 is connected to earth through the switch 63, magnet 66, segment 26, and arm 27, the magnet 66 opening the switch 67 to de-energize the magnet 13a.

Title: Electrical control device
IPC: H03F9/04
Filed: 1952-09-12
Abstract: 705,242. Magnetic amplifiers. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET Sept. 12, 1952 [Sept. 22, 1951], No. 22932/52. Class 40 (4) A temporarily acting D.C. control signal applied to a magnetic amplifier causes an alteration in the output which persists after the signal terminates. The extent of the output alteration may also be determined by the duration of the control signal. As shown in Fig. 1, the amplifier has a three-legged core 1 carrying A.C. load windings 2, 3 and a D.C. winding 5, the centre leg being traversed only by D.C. flux and comprising a portion 4 having a high remanence and coercive force.  The manner of operation is shown in Fig. 2 in which i1 is a D.C. bias current giving a load voltage corresponding to point F. When a D.C. control current i2 is applied, the load voltage rises to point B and falls only slightly to point D when the control current ceases, due to the wide hysteresis loop. In a circuit arrangement, Fig. 3, the load windings 2, 3 are energized in series with a load 12 from an A.C. supply 10 and are connected with rectifiers 7, 8 to provide auto-excitation. A self-magnetizing winding 5 is energized from a rectifier 11 while a bias current corresponding to il is applied to winding 13. The control current acts in winding 6 over a delay circuit comprising a capacitor 15 and a resistor 16 and its polarity and duration is determined by contacts 18 and 19. Due to the delay circuit, the extent of output variation depends on the time a contact 18 or 19 is closed. The delay circuit may alternatively be connected in the self-magnetizing circuit or the output circuit and may comprise a capacitor, an inductor or a thermistor.

Title: Improvements in pipe couplings
IPC: F16L13/10
Filed: 1946-08-02
Abstract: 613,493. Pipe couplings. VICTAULIC CO., Ltd., and JOHNSON, P. G. Aug..2, 1946, No. 23110. [Class 99 (i)] In a method of coupling pipes 5 lined with bitumen or other plastic material 6 by means of a socket on one pipe which engages. over the other pipe (Fig. 2), or a coupling.sleeve 7 which engages over the ends of both pipes (Fig. 1), a gap is left between the linings of the pipes, a backing-up ring 11 of rubber or like material is inserted to bridge the gap and pressed into engagement with the inner surfaces of the linings, melted lining material is poured through a hole in the socket or sleeve to fill the annular space between the pipe ends, the linings and the ring 11, the material is allowed to solidify, and finally the ring is removed and the hole closed by a plug. A continuous lining across the joint is thus obtained. A funnel 12, screwed into the hole, is used for the pouring. A second funnel is provided in another hole at the highest point of the sleeve or socket; this serves as an air vent. The backing-up ring 11 may be made of a strip whose length is greater than the lining bore so that itis self-compressed into position on insertion. It may also be a sleeve of smaller outside diameter than the bore, in which case a device as shown in Fig. 4 is required for expanding it into contact with the lining. The sleeve 16 is externally cylindrical and has internal tapering portions. These portions are engaged by expander members 17, 18, which can be drawn together (as shown) to expand the sleeve, or moved apart (chain lines) to contract it. Each expander has three wheels- 19, the positions of which can be adjusted radially by screws 21. Expander 17 is carried by a shaft 22 which has a threaded extension in engagement with expander 18. Relative rotation of the expanders is prevented by two guide pins 24 so that rotation of the shaft 22 moves the expanders towards or away from one another. Specification 392,287 is referred to.

Title: A machine for stringing tags for sliding clasp fasteners, actuated by hand or mechanically
IPC: A44B19/46
Filed: 1947-08-21
Abstract: 643,346. Sliding-clasp fasteners. PLANAS. A. C. Aug. 21, 1947, No. 23175. Convention date, Dec. 6, 1946. [Class 44] In a manually or mechanically. operated machine making sliding-clasp fasteners, the fastener elements are applied to the tape by the following steps: (a) the elements, mounted with their legs astride a horizontal rail, are gradually fed forward; (b) the elements are dropped on to the tape; (c) the legs of the elements are clamped on the tape; and (d) the tape is moved forward to the next position. The machine shown in plan in Fig. 1 comprises a frictionally braked tape reel 2 from which the tape 4 passes under the rail 6 through the several devices comprising the machine to a drum mounted on a ratchet wheel 13 operated by a pawl 17 through levers 14, 15, 16. The elements are urged forward by an arm 8 connected by a cable to a spring m. At the end of the rail the elements pass in turn through an aperture of the same shape in a plate a, Fig. 4, which also has a slot to guide the tape. After passing through the aperture the elements are moved down on to the tape by a slider c and the legs of the element are clamped on the tape by transverse hammers M, Fig. 5, normally spring- loaded apart but closed by cam plates 12 mounted on a shaft 12a actuated by the main operating lever 11. An adjustable stop T cooperates with an arm O on the shaft 12a to vary the stroke of the hammers. The elements are supported by their legs during the clamping process by guides PH. The completed fastener tape is passed round a drum on the ratchet wheel 13 against which it is held by a pulley TC, Fig. 1. The ratchet wheel 13 is clamped by a friction belt and turned by the pawl 17 on the return movement of the lever 11. Spaces may be formed in the tape by operating a second pawl lever 18 which moves the tape without operating the element applying mechanism. The reel 2 is mounted on a flanged spindle passing through a flanged pedestal and reduced at the lower end to receive a spring adapted to put pressure on a friction washer held between the flanges. The guide rail is mounted by a readily releasable fastening, e.g., a bayonet fastening, so that it may easily be replaced when empty.

Title: Snap action electric switches
IPC: H01H37/50
Filed: 1954-08-10
Abstract: 762,045. Thermal switches. SIGNALSTAT CORPORATION. Aug. 10, 1954 [Aug. 18, 1953], No. 23176/54. Class 38(5) A normally closed snap action electric switch comprises a snap acting vane, the action of which is controlled by an electrically conducting strip attached thereto, the arrangement being such that as the strip expands due to the passage of an electric current therethrough causing heating of the strip, the pressure on the contact is maintained, and increased, right up to the instant the vane snaps over to separate the contacts. A snap acting vane 10, the construction of which is more fully described in Specification 761,713 [Group XXXII], is deformed along a diagonal as at 15, 15 to give the vane an initial set so that the vane 10 normally forms a shallow vee (V) the apex of which is along the diagonal 11, 12. The central area of the vane is not deformed in order that the vane may be more resistant to fatigue and thus to have a longer life. An expansible conducting strip or wire 30 is secured to the ends 11, 12 of the deformation at points 31, 32, so that, in its unexpanded state the wire 30 is under tension urging the points 31, 32 towards each other, the vane being forced to assume a shallow vee (V) with its apex along the diagonal 16, 17. The wire 30 is provided with a contact 35, a co-operating contact 25 being insulatingly mounted on a mounting member 20 to which the vane 10 is secured. Current from a battery 44 passes to the contact 25 by way of a lead 45 and connecting strip 43, into the contact 35, through both halves of the wire 30 in parallel, into the member 20 and back to the battery 44. The wire thus heats up and expands and in so doing allows the vane 10 to snap over into its originally deformed state with the vee (V) apex along the diagonal 11, 12, thus opening the contacts 25, 35. The wire now cools and contracts, returning the vane and contacts to the positions shown. With the arrangement described, the contact pressure is maintained up to the point where the vane snaps over, the current waveform is therefore substantially square in shape.
