Title: Apparatus for the mechanical handling of coiled, looped or annular bodies
IPC: B21C47/24
Filed: 1951-04-11
Abstract: 706,498. Unloading coils or the like from overhead conveyers. BRIGHTSIDE FOUNDRY & ENGINEERING CO., Ltd., and BROWN, J. L. April 10, 1952 [April 11, 1951], No. 8417/51. Class 78 (1) Coils 22 of rod or wire or like annular bodies are discharged from loops 12 on an overhead conveyer to arms 34 of a storage device by a platform 24 mounted for up-and-down movement on a wheeled carriage 11 reciprocated on a bed plate 10. The carriage is reciprocated by a connecting rod 14 actuated by a crank 15 secured to a shaft 16 driven through gearing 18 by a motor 19. The platform 24 is slidably mounted on a bracket 20, fixed to the carriage 11 and has upward movement imparted to it by a lever 25 mounted on a shaft 26 and commected at one and by links 27 to the platform and at the other end connected to links 28 engaged by a pin 29 secured to the connecting rod 14. As a loaded hook 12 approaches the unloading point, contact is made with a switch or like device to set the apparatus in motion. As the carriage is moved forward, rollers 32 supporting the ends of the shaft 26 move up a cam path 33 secured to the bed. plate whereby the platform is raised quickly and the coil lifted off its hook and carried forwardly. After this point in the stroke of the carriage, the platform falls quickly due to the fall in the cam path 33 and the coil is deposited on the end of an arm 34. It is then pushed along the arm during the remainder of the forward stroke, the platform resting on stops at a level below the bottom of the coil. As each coil is deposited on the arm the preceding coil or coils are pushed further on to the arm. At the completion of the return stroke of the carriage, the machine is stopped by the action of a limit switch (not shown). The arms 34 are pivotally mounted on the spider 35 of a pillar 36 rotatable by a motor 37 so that as one arm is completely loaded another arm can be brought into loading position. The conveyer may be unloaded whilst it is moving or after it has been stopped.

Title: Methods of coating electrical units with ceamic material in a vitrified matrix
Inventor: HAMER LOUIS HARRY BERKEL
IPC: C23D5/00
Filed: 1964-02-28
Abstract: An electrical unit comprising an electrically-conductive metal element on a rigid core of insulating material is coated with a mixture of a glassy material and at least one particulate refractory ingredient of higher fusion point than the particulate glass, made into a plastic mixture with water, the coating being moulded around the conductive element and the thus coated unit fired at a temperature between the fusion points of the glass and refractory ingredients, the proportions of the ingredients of the mix and the firing conditions being such that the heating results in the production of a vitrified matrix but does not result in any substantial change in the size and shape of the coating of the mix moulded around the element.  A glass frit is first prepared by melting at 2500 DEG  F. a batch containing silica, borax, feldspar, clay, fluorspar and possibly the oxides of tin, antimony and zirconium, and pouring the melt into water.  The frit is then ball-milled and a quantity of this is then further mixed with the refractory ingredient in a ball-mill, water being added to give a plastic mix. This mix can be applied direct to the electrical unit or preformed to a shape which can subsequently be placed over the unit. When the unit has been coated, pressure may be applied to mould the preform into more intimate contact with the unit.  The assembly is then fired. Preferably the ratio of refractory to glass is high.

Abstract: 609,782. Arc welding electrode holders. GENERAL ELECTRIC CO., Ltd., BAKER, W. F., and BROWN, J. W. March 22, 1946, No. 8887. [Class 39(iii)] [Also in Group XXXVII] A holder for a pair of electrodes to be used in unison especially of the kind in which two parallel rods are embedded in a single body of flux, comprises a body 2 with a tubular hand grip 9 and carrying a pair of electric conducting elements 15, 20 co-operating to grip between them the electrodes, the conducting elements being insulated from one another and being moved in a direction parallel with the axis of the hand grip to grip or release the electrodes. A body 2 of insulating material of I section in a hand grip 9 carries on opposite sides copper strips 5, 6, to which current is fed by members 7. The electrodes are held between a fixed jaw 20 and a sliding jaw 15 on the body 2. A spring 14 bears on the jaw 15. The strips 5, 6 are outwardly flared and pressed apart by a spring 35 and carry contacts 10, 11 cooperating with a contact 21 on a conductive strip 18 on the body carrying jaw 20 and with a contact 17 on a bar 16 sliding on the opposite side of the body 2 and contacting the jaw 15. A yoke member 22 pivoted at 23 on the body 2 is moved by a lever 24. Pins 27, 28 on extensions 29, 30 of the strips 5, 6 engage in cam slots 25, 26 in each limb of the yoke so that downward movement of the lever 24 closes the contacts. The sliding bar 16 carries a block 31 having pins 34 in slotted links 32 on the yoke, so that when the lever 24 is moved upwardly, the bar 16 draws back the jaw 15 to release the electrodes. The jaws 15, 20 may be connected to separate phases of a two phase supply. Two separate levers on opposite sides of the holder may be operated, one by the fingers to control the switch, and the other by the thumb to release the electrodes. In Fig. 3 the electrodes are gripped between a conducting rod 36 and the wall 38 of an aperture in a conducting tube 40 sliding on an insulating sleeve 41 on the fixed rod 36. A spring 43 urges the tube 40 back to grip the electrodes. Within a hand grip 37 are two two-pole switches 50 each having a conductive bridge 51 bearing on a pair of contacts 48. The switches are operated by a lever 54 pivoted at 57 on the body to connect the two supply cables 47, one to the rod 36 and the other to the tube 40. The lever 54 closes the switches against a spring 53 through an insulating thimble 55. A pin 58 passes through slots in the sides of the holder and through the tube 40, so that on moving the lever 54 away from the holder, the pin 58 is engaged by lugs on a yoke 56 on the lever so as to move the tube 42 forwards to release the electrodes. The switch contacts are copper faced with silver. The electrodes may extend at 45 degrees to the plane of movement of the lever. Specification 593,350 is referred to.

Abstract: 1465527 Vehicle electrical systems K AZUMA 27 Feb 1974 8977/74 Heading H2H The output of the generator of a motor vehicle is regulated according to the speed of the generator by short-circuiting a part of a resistor in series with the generator field winding by means of a triac. A generator 1 of a motor vehicle comprises a stator winding 2 and a field winding 4, the output of the stator winding being rectified by a bridge 3. At low generator speeds the field winding 4 is supplied from the vehicle battery 17 by way of the ignition switch 6, when closed and a triac 5. Under these conditions a transistor relay 8 is inoperative whereby a second triac 16 is non-conductive a small A.C. signal thus being applied to the gate of triac 5 through all the resistor 7 resulting in a low current in the field winding 4. Upon an increase in generator speed and the generated D.C. from the bridge 3 reaching a predetermined value, the transistor relay 8 becomes operative to provide a gating signal for the triac 16. Conduction of triac 16 short circuits part of the resistor 7 which causes the current in the field winding 4 to increase thus increasing the generated D.C.

Title: Improvements in Method of and Apparatus for Mixing Dough.
Inventor: PATTERSON CURTIS JOHN
IPC: A21C1/14
Filed: 1919-04-09
Abstract: 134,756. Patterson, C. J. April 9, 1919. Regulating the proportions of a mixture. -Consists of a method for forming a plastic mass such as dough from a pulverulent material and a liquid, by first introducing all the material and the bulk of the liquid and then adding the balance of liquid in uniformly measured quantities. As described, the amount of additional liquid is controlled by the consumption of the driving motor, the supply being cut off when the load is reduced to that level which indicates the correct consistency of the mixed mass. The mixer 1 has its stirrer shaft 2 driven by an electric motor 6, the leads 7, 8 having a low-resistance shunt consisting of conductors 30, 31 bridged across a shunt resistance r, a rehostat 32, an electro-magnet 29, and a contact breaker 33, the rotating element 34 of which is driven from a separate motor 38 which also drives a recorder 42. The armature 27 of the electro-magnet is connected to a stem 21 of a double valve 18, 20 controlling the entry and exit to a chamber 16 forming a nozzle to supply liquid to the mixer from the chamber 12 of a double tank, the other chamber 11 of which supplies liquid through a nozzle 14. The initial proportion of liquid is introduced from the chamber 11, with all the material. The motor is then switched on, the rheostat being adjusted so that the magnet 29 is only energized to substantiate the saturation point at any predetermined load. Each time the contacts 34, 35 come together, the armature 27 will raise the valve stem 21 and empty the contents of the chamber 16 into the mixer, and when the contacts part the stem will fall by gravity to allow the chamber to refill. When the consistency of the mixture is thin enough to reduce the load below that pre-determined, the armature will cease to be attracted. An ammeter 10 is provided in the motor circuit.
