Title: Quick acting gate
Inventor: CORCORAN JOHN WEEDEN
IPC: G03B9/08
Filed: 1962-05-09
Abstract: 972,728. Valves. BECKMAN & WHITLEY Inc. May 9, 1962, No. 17818/62. Heading F2V. [Also in Division G2] A quick-acting gate or shutter comprises a circular disc of electrically conductive material, rotatably supported about a diametral axis, so disposed that the establishment of a magnetic field induces a current in the disc which, by interacting with the said field, causes rotation of the disc. In the form shown, the disc 14 is of aluminium, with pivotal bearings 16 at each end of a diametral axis, and is mounted inside a solenoid 11. When the solenoid is energized, a magnetic field is established as indicated by flux lines 17. These are intercepted by disc 14, causing a current to flow in the disc in circular paths. The interaction between this current and the magnetic field causes the disc to rotate. When the disc is coplanar with the solenoid, the induced current is at a maximum, but the rotational force is zero. When the disc is perpendicular to the solenoid, the induced current is zero, but the rotational force is at a maximum. Thus the optimum condition for rotation is when the disc is at 45 degrees. Control of the movement of the disc is achieved by suitable choice of the duration and shape of the energy pulses applied to the solenoid.

Abstract: 385,003. Filling pies &c. CHRISTIANSEN, E. and ERICSSON, C. O., Food Machinery Works, Woodfield Road, Balsall Heath, Birmingham. June 22, 1931, No. 17955. [Class 28 (i).] In a machine for delivering jam, custard, or other material in predetermined quantities into pie casings or containers, of the type in which the material is ejected by a reciprocating piston 1 from a measuring chamber 3 at the lower end of a hopper 2 through an outlet 4 into a container which is lifted by a vertically reciprocating table 6 towards the outlet for receiving the material, there are provided automatic means for feeding a container to be filled over a stationary table 5 on to the vertically reciprocating table and for removing a filled container therefrom. The feeding means comprises a slide 33 mounted in a slotted guideway 34 on the table 5 and operated by a pivoted lever 35 and a roller 39 thereon which is held against a rotating cam 40 by a cord 42 and weight 41 ; the cam 40 is mounted on a rotating shaft 13 connected through gearing and a clutch to an electric motor 19. The slide pushes a tin into position on the table 6, at the same time pushing the tin already on the table off on to the stationary table ; should any obstacles get in the way of the slide 33 the only force which can be applied to the obstacles will be the pull of the weight 41. The vertically reciprocating table 6 is operated by a rod 7, pivoted lever 11 and a cam 12 on the shaft 13. The end of the rod 7 is bifurcated and is provided with holes 9 for receiving a pin 10 against which one end of the lever 11 bears ; by adjusting the position of the pin the height to which the table is raised mav be varied. The end of the lever 11 engaging the pin 10 may be in the form of a spring-controlled arm 11b so that the force raising the table cannot be greater than the strength of the spring. A stirrer 56 may be mounted in the hopper 2 and rotated by gearing from the motor 19 ; this gearing includes a square portion '60a on a shaft 60 engaging a square hole in a shaft 61 so that by releasing a catch handle 62 the casing 63 carrying gearing and the stirrer can be easily detached to enable the hopper to be filled. The actual delivery-mechanism and means for varying the quantity of material delivered are substantially the same as those described in Specification 356,151, [Group XXVI].

Title: An improved electric steelyard weighing machine
IPC: G01G1/38
Filed: 1920-07-05
Abstract: 146,843. Schember, K., and Joksch, R. July 8, 1919, [Convention date]. Sliding-weight apparatus.-Relates to a weighing machine having two or more graduated steelyard arms carrying poises of different weighing capacity, the poises being automatically and successively moved along the arms by a single electric motor, and consists in controlling the circuits for the different poises by a series of contacts opened and closed by the small arm of the steelyard acting in conjunction with a load-resisting spring, or the like, which becomes inoperative at the balancing point. In the construction shown in Figs. 1 and 3, the steelyard, pivoted on a knife-edge 2, has two arms 3, 4 provided with poises 8, 9 respectively, of the kind described in Specification 146,089, and the load is applied through a rod 5. Above the steelyard are two poise-adjusting devices 10, 11 mounted upon screws 16, 17 driven by a polyphase motor 22 through clutches 27, 28. The clutches are put into action by bent levers 29, 30 attracted by electro-magnets 31, 32. Assuming the two poises 8, 9 to be at zero and a load to be placed on the machine, the short arm 7 of the steelyard depresses a spring 41 together with contacts 43, 55. The contact 55 bridges contacts 57 and starts the motor 22. The contact 43 bridges contacts 45, 47 and thus energizes the electro-magnet 32 which then puts in its clutch 28 and causes the major poise 9 to move along the steelyard until the contact 43 leaves the contact 47 and bridges the contacts 45, 46. The electro-magnet 32 is de-energized, the clutch lever 30 falls and the movement of the poise 9 is arrested. The fall of the clutch lever 30 closes contacts 35, 36 thus energizing the electro-magnet 31 and placing the corresponding clutch 27 in operation so as to move the minor poise 8 along the steelyard. At the balancing point, the contact 43 leaves the contact 46, de-energizes the electromagnet 31 and arrests the minor poise 8. If the load on the machine is reduced, a similar series of operations to that described above takes place in connexion with contacts 44, 56, the motor being reversed. The screws 16, 17 for propelling the poises are provided at the ends with non-magnetic disks 37, 38 each containing an iron armature and rotating between the poles of an electro-magnet 39 or 40. These electro-magnets are energized when the clutch levers 29, 30 fall on to their contacts, and the action on the iron armatures assists in positioning the poise-adjusting devices 10, 11 exactly in their notches, and also produces a braking effect on the movement of the poises. The first and last notches of the bars 18, 19 are provided with contacts 51 - - 54 for engagement by the positioning teeth 20, 21 of the poise-adjusting devices whereby, in the event for example of the major poise 9 being prematurely arrested due to imperfect action, the positioning tooth 20 of the minor poise 8 by engaging the contact 521 closes an auxiliary circuit and re-starts the major poise, the balance being afterwards automatically restored.

Title: A method of and apparatus for forming a light metal cap
IPC: B21D51/38
Filed: 1954-06-28
Abstract: 756,621. Making bottle caps. AKTIEBOLAGETWICANDERSKORKFABRIKER. June 28, 1954 [June 29, 1953], No. 18925/54. Classes 83 (2) and 83 (4). [Also in Group XVII] Stamping.-A method of making a light metal bottle cap provided with a tongue for tearing off the cap in a cutting-out and shaping tool is characterized in that the edge portion of the cap excluding the edge of the tongue is deflected back upon itself by bending the edge portion against a supporting ring and then subjecting the edge to an evenly distributed pressure between opposed surfaces of the supporting ring and punch which extend around the axis of the tool from one side of the tongue to the other. The tool comprises an upper part attached to the machine head 3a slidably mounted in a guide 4 and a lower part mounted on the machine table 3. The head is actuated by a cam on the drive shaft 7. The upper part consists of a sleeveshaped cutting punch 10, a die 11 attached to a sleeve 12 surrounding the punch and a stamp 14 within the punch. The lower part consists of a member 15 fixed to the table 3, a spring- loaded supporting ring 16 reciprocable in said member 15 and a reciprocable spring-loaded mandrel 18. The punch 10 is fast with a sleeve 20 mounted on the machine head and the stamp is spring-loaded and movable within the punch and a guide sleeve 24. A spindle 27 and link 28 connects the stamp to a pivoted lever 29 cam operated from the main shaft 7. In operation, a metal strip 2 is fed stepwise into a slot 26 above the die 11. Between each step the punch cuts out a blank which is carried down on to the supporting ring 16 and mandrel 18. As the punch continues downwards, the stamp engages the blank and the supporting ring gives way as the blank is formed over the mandrel 18. Before the punch reaches its lowest position the lever 29 comes into action to press the edge of the formed cap, which is tightly held between the stamp and the mandrel, against the supporting ring 16 which is prevented from further downward movement by the member 15. An oblique surface 40 on the supporting ring outwardly deflects the edge and, when the punch moves upwards, the supporting ring presses the deflected edge of the cap against the bevelled edge of the punch and completes the fold to form a cap as shown in Fig. 1.
