Patent GB-333631-A (GB)
Abstract: 333,631. Dehn, F. B., (Fuller Brush Co.). May 18, 1929. Angular bending ; dies and formers; shearing ; embossing ; metal sheet feeds. - A machine for simultaneously operating on a series of blanks while the blanks occupy stations corresponding to successive stages of manufacture, and described particularly with referenee to stamped trough shaped articles, comprises a reciprocating gripper 18 for intermittently feeding a strip and a pusher 28, offset from the line of movement of the strip, for delivering a completed blank from the machine. The slide 14 carrying the grippers 16, 18 is reciprocated on a guide bar 15 by linkage 20, 21 actuated by a cam, retrograde movement of the strip being prevented by a weighted gripper 30. The strip is fed into a channel in a housing 34, Fig. 5, carried by a lower die 35 and is pressed upwardly in the channel by a spring-button 37, the strip thus being guided by a chamfer 47 between a previously severed blank 40 and a second spring-button 46 carried by an upper block 39 in which are mounted a severing cutter 38, dies for marking or embossing the strip and a die 63, Fig. 7, for shaping the severed blank over a former 64. The marking or embossing dies work through apertures 49, Fig. 3, and the severing cutter through an aperture 48 in the housing 34, the marking of part of the strip being effected simultaneously with the cutting off of the previously marked blank. The cut-off blank 40 on being depressed from the channel in the housing by the entering strip is moved transversely by cam-actuated transferring fingers 51, past a spring-pressed positioning pin 60, Fig. 7, over a stationary former 64 against a stop 61 on a second positioning-pin 62, the pins 60, 62 holding the work on the die 63 during the forming operation. A spring-pressed ejector 65 may be mounted in the forming die. On completion of the forming operation, the work is removed by the pusher 28, Fig. 3, which is trough shaped to correspond with the former. The die-block 39 carries guide pins 42 working vertically in the stationary lower die block 35 and is supported by springs 44, limit stops for the upward movement of the block 39 being provided. A ram reciprocated by a crankshaft actuates the block 39, litting hooks being mounted in the ram to ensure upward movement of the block.

Title: Improvements relating to micro-porous diaphragms, or separators for use in electric accumulators
IPC: H01M50/477
Filed: 1945-12-10
Abstract: 604,957. Batteries. CHLORIDE ELECTRICAL STORAGE CO., Ltd. (Duddy, J. C.). Dec. 10, 1945, No. 33366. [Class 53] [Also in Group V] Porous diaphragms such as battery separators are made from a mixture of porous particles and particles of a thermoplastic binder. The binder particles are of a non-spherical shape and after the mixture has been formed into the required shape heat is generated within the mixture by high frequency currents to render the thermoplastic particles coherent and to cause them to change their shape whereby they become interlocked with the porous particles. Fig. 1 shows an apparatus for making the diaphragms. The two kinds of particles are placed in hoppers 10, 11 and allowed to flow into a mixer 15, the proportions of the two materials being controlled by adjustable vanes 12a, 12b. Alternatively, the materials may be introduced in the desired proportions directly into the mixer from which thev flow into, a mould 19 made of insulating material. The mould has a bottom plate 20 made of metal which has a terminal 22 connected to a high frequency generator 25. The other lead 26 from the generator is connected to a metal plate 29 which is placed on top of the mixture in the mould. To facilitate removal of the finished diaphragm while the mould is still hot the plates 20, 29 may be coated with a soap solution or covered with paper or cotton fabric impregnated with a phenolic resin. A thin mat of glass wool may also be used and this will adhere to and form an integral part of the diaphragm when removed from the mould. Fig. 3 shows a mould for producing a ribbed separator in which the metal electrodes 33, 34 are provided with insulating strips 37 having a dielectric loss factor approximately the same as that of the mixture in the mould. The strips 37 may be made of various woods, thermosetting plastics, glass, &c. The ribs and intervening web portions of the finished diaphragm may be given different porosities by varying the material of which the strips 37 are made and so varying the field between parts of the electrodes 33, 34. The high frequency heating effect is greater at the centre of the mould than at the surfaces where heat is conducted away by the metal electrodes. The bonding of the particles is therefore greater in the centre plane of the finished diaphragm than at the surfaces where the porosity is accordingly greatest. The porous particles used in the manufacture of the diaphragms may consist of diatomaceous earth, wood flour, silica, gel, bentonite, etc., and, the thermoplastic binder may consist of a copolymer of vinyl chloride and vinyl acetate, polyethylene, polystyrene, or other thermoplastic resin or mixture of resins.

Abstract: 892,101. Masers. VARIAN ASSOCIATES, and BLOCK, F. April 29, 1958 [May 2, 1957], No. 33586/61. Divided out of 892,100. Class 40 (9). [Also in Group XXXVI] In a gyromagnetic spectrometer including an oscillator 106 feeding a coil 95 adjacent a sample 91, a coil 93 for detecting gyromagnetic resonance in the sample and an amplifier 104, either the amplifier, the oscillator or both may include a gyromagnetic maser, the magnetic polarizing fields of the spectrometer and the maser or masers being parts of a common field. The oscillator has a fixed frequency and the effective magnetic polarizing field is controlled by a sweep generator and coils 97. The output of the maser 104 is fed to a conventional amplifier 101, a detector 102 and a recorder 103. Masers.-Any of the nuclear gyromagnetic masers described in Specification 892,100 may be used. The maser shown in Fig. 20 is of the kind shown in Fig. 17. The working substance 1 flows downwards as shown in a polarization field having a gradient due to the tapered polepiece or pieces 79. A radio frequency source 12 drives the winding 78 at the Larmor frequency of the working substance. As the working substance passes from coil 78 to coil 3, the magnetic moment is reversed and the material is in a high energy state ready for stimulation by a signal at the Larmor frequency for the field between the parallel portions of the polepieces 79. The coupling between the tuned circuit 3, 4 and the working substance determines whether the maser amplifies or oscillates. A maser which is not described in Specification 892,100, is shown in Fig. 12. The working substance 65 is magnetically dilute gadolinium ethyl sulphate having cerium as an additional impurity. Alternatively, it may be a single crystal of nickel fluosilicate. These materials each have two gyromagnetic ensembles with resonance frequencies in the microwave range. The cavity resonators 66 are resonant at the resonance frequencies of the two ensembles. A source 67 of oscillatory energy at the Larmor frequency of one ensemble is coupled to the cavity resonators 66 via a waveguide 68 and a coupling iris 69. The substance 65 is polarized by a magnetic field Ho as shown. The output is taken from a waveguide 71 and a coupling iris 72.

Title: Improvements in bobbin strippers
IPC: B65H73/00
Filed: 1928-11-16
Abstract: 325,494. Terrell, E. A. Nov. 16, 1928. Bobbins, stripping w a s t e from. - In bobbin-stripping machines of the type having blades or the like by which the waste on the bobbin is removed by a scraping action taking place lengthwise along the bobbin barrel, the stripping means 45 comprise broad-faced stripping blades adapted to engage exteriorly the mass of waste left on the bobbin and chisel-ended stripping blades adapted to engage the bobbin between the mass and the shoulder of the bobbin, so that when the bobbin is seized and drawn along by jaws 29, 30 on a cross-head 4 the waste will be stripped from the bobbin. The bobbins are fed down. a shoot and laid horizontally in turn with the head resting on the head rest 47. A shutter 36, Fig. 7, prevents any movement of the upper bobbin during the pulling operation of the gripper jaws. This shutter is pivoted at 361 and a slot 366 in the arm thereof has working in it a piece 364 fixed at the upper portion of a pull rod 362 connected to an arm 363 on a rock shaft 179 by which the opening and closing of the stripping blades is effected. The lost motion effect of the piece 364 in the slot 366 provides the freedom of movement necessary to avoid breakage in case the shutter lands on the top of a bobbin head projecting under it. The guide-way or shoot for feeding the bobbins, and the stripper blade operating mechanism are described in Specification 325,497, the gripper jaw operating mechanism is described in Specification 325,498. Specification 325,496 also is referred to.
Patent GB-1305890-A (GB)
IPC: B30B9/30
Filed: 1971-07-19
Abstract: 1305890 Compacting refuse L P WHITE 19 July 1971 [17 July 1970] 33723/71 Heading B8C A method of compacting refuse comprises the steps of feeding refuse into an open-ended enclosure 8, 10, forcing the refuse through the enclosure through a curved path 10 to increase the frictional resistance of the enclosure to movement of the refuse therethrough thereby effecting compression of the refuse, and, after the refuse has been compacted to a predetermined degree, expelling the compressed refuse through an open end of the enclosure. As shown, refuse, introduced into a rectilinear section of the enclosure 8, 10 through a hopper 24, is forced, by a ram 42, 44, 46, 48 operated by a cylinder 32, past a reduced neck section 57 and into a curved section 60 until the ram reaches its maximum throw whereupon the ram is retracted. The cycle is repeated, the passage of the refuse completely through the curved section being prevented by a gate arm 82 which is maintained in its projected, operative, position across the path of the refuse by a pulley and counterweight mechanism 84, 92. When, after repeated movement of the refuse along the curved section, the pressure of the refuse overcomes the counter-pressure of the weight 92 the gate is rotated to its open position to be flush with the side of the curved section, and the refuse is ejected from the open end of the section 10 into a bag 66. The gate 82 swings back to its operative, obstructing, position after the pressure within the section 10 has fallen below the predetermined level. The degree of refuse compaction can be controlled by adding, or removing, weights, or by changing the sharpness of the curve, or curves, in the section 10. The ram carries along each top side edge a strip 54 which engages beneath a corresponding guide rail 56 mounted along the interior of the adjacent side 20 of the enclosure so that the ram is prevented from moving vertically during its horizontal stroke.

[Class 80 (ii)] A centrifugal friction clutch comprises a driven disc 13 which is spring- connected to its hub 15 and disposed between a driving flywheel 11 and a presser plate 12 rotating with the flywheel. Centrifugal weights 37 have feet, the rounded heels 41 of which pivot against the angle of the cover plate 21 secured to the flywheel and the toes 39 of which engage between the plate 21 and a plate 33, which latter is urged towards the former by springs 42. These springs act between the plate 33 and adjustable nuts 44 on studs 45, the heads of which abut against the outside of the plate 21. The nuts 44 are slidable in apertures in the plate 12. Pressure springs 34 and 46 act between the plates 12 and 33, the springs 46 being arranged around studs 47 which are secured to the plate 12 and the adjustable heads 48 of which engage behind the plate 33 so as to maintain the springs 34 and 46 under a predetermined stress. At a predetermined speed, the weights act to move the plates 33 and 12 to the left as a unit to produce initial engagement of the clutch. As the speed increases, the plate 33 moves away from the heads 48 and full engagement under the pressure of the springs 34 and 46 results. The cover plate limits the outward movement of the weights. Manual disengagement can be effected through radial levers 28. U.S.A. Specifications 1,931,674 and 1,931,675 are referred to.

An hydraulic pressure transmitter for hydraulic braking systems, having an auxiliary source of hydraulic pressure comprises a body 1 having coaxial bores 2, 3, the bore 2 containing a piston 15 on a rod 14 and connected to a controller 18, the smaller bore 3 communicating with receiving apparatus through a port 13 and receiving a part 34 of rod 14, and a fluid pressure regulating valve 33 operated by the rod part 34 to regulate the supply to bore 3 of auxiliary fluid from connection 11, a rod part 19 entering bore 3 in a fluid-tight manner when the rod opens valve 33. High pressure fluid in connection 11 forces a shuttle 25 to close a port 27 and open port 26 to supply fluid past grooves 30 to chamber 23 and via a pipe, not shown, to a chamber 22. When piston 15 is moved in the direction F on braking, a ball 35 rides up cam 39 to raise ball valve 33 to supply fluid from chamber 22 to chamber 6 via ports 37, 38 in the piston rod. When pressure in chamber 6, corresponding to brake cylinder pressure, exceeds pedal pressure on piston 15, the piston and rod 14 are moved to the right, firstly to close valve 33 and then to move part 19 from bore 3 to allow fluid to pass from bore 3 to bore 2 and to a reservoir via port 21 and connection 5. The slope of cam 39 determines the progressiveness of braking. Should the auxiliary source fail, then spring 25 returns shuttle 25 to close port 26 and open port 27 so that the transmitter acts as a master cylinder, fluid being forced from chamber 4 via passage 28, port 27, chambers 23, 22 and valve 33 to chamber 6.
