Title: Improvements in or relating to control systems
IPC: B26D7/06
Filed: 1962-06-15
Abstract: 991, 972. Electric correspondence control systems; weighing apparatus. SWIFT & CO. June 15, 1962 [Aug. 22, 1961], No. 23231/62. Headings G1N and G1W. [Also in Division. H3] A method of controlling a feeding operation comprises the steps of sensing at least one dimension of the material being fed and developing a signal representative of the volume having passed a given point and interrupting the feed when the signal reaches a given magnitude. As described, the feeding of bacon through a slicer is controlled to obtain groups of slices of uniform thickness and total weight. The control system comprises a timer circuit in which the beginning of a timing cycle is initiated by closing a manual switch 102, to energize relay 100 closing contact 103 and thus shorting out the cathode resistor 40 and firing thyratron 36. Relay 34 energizes and contacts 48 then closes allowing thyratron 52 to fire. Relay 55 then energizes closing contact 77 to allow thyratron 80 to fire opening contact 92. All three thyratrons then become de-energized, and the timing cycle commences. Potentiometers 11 are connected to sensing devices which measure the dimensions of the bacon fed through the machine, the potential derived from their sliders is fed to an integrator 26 the output from which is proportional to the volume of bacon which has passed through the slicer, and is fed to the grid of thyratron 36. The cathode of thyratron 36 includes a resistor 40, part of which is shorted out once per revolution of the cutter blade, to feed to the thyratron a voltage representative of an average slice of bacon. When the sum of this voltage and the output from integrator 26 produce a sufficient grid-cathode voltage thyratron 36 strikes energizing relay 34 as referred to above. Contacts 50 change-over deenergizing the feed solenoid 57 and energizing "dwell" relay 59 so that the feeding of the bacon through the machine is discontinued. After a time determined by the output from integrator 64 thyratron 52 fires, completing anode circuit for thyratron 80 and at the end of the next cut switch 90 is closed by the blade to fire thyratron 80 thus initiating a fresh cycle as described above. A limit switch 94 closes at the end of a joint of bacon to operate relay 95 shorting both integrators and resetting the machine for a new joint.

Title: Heated filament for thermionic valves
IPC: H01J1/16
Filed: 1928-08-13
Abstract: 295,637. Loewe, S. Aug. 15, 1927. [Convention date]. Vacuum tubes.-A filament cathode or a heater for a cathode is made of different resistance at different points, the resistance at the ends being greater than at the middle. This may be effected by varying the cross-section, as by attaching a second piece of filament 3 to a tungsten filament 2, or by using materials of different specific resistance, or emissivity. The filament may be used in multiple valves.

Abstract: 473,924. Knitting-machines; knitted fabrics. GETAZ, J. L. Aug. 25, 1936, No. 23308. Convention date, Dec. 10, 1935. [Class 74 (ii)] The starting up of seamless elastic hosiery on a circular knitting-machine is effected by interlacing an elastic yarn 20 alternately in front of and behind the needles, feeding a second unelastic yarn 12 to the hooks of all the needles and drawing alternate loops on opposite sides of their first yarn. The elastic yarn may be inserted under tension say at every third course in the welt or other part of a stocking, the contraction of the said yarn causing the welt &c. part to appear ribbed.

Abstract: 456,603. Projectile fuzes. GIRARD, P., 4, Place Puvis-de-Chavannes, Lyons, France. Aug. 21, 1935, No. 23520. Convention date, Aug. 24, 1934. [Class 9 (i)] Relates to clockwork fuzes of the kind in which the clockwork is wound and set by a member which can be rotated several times around the axis of the projectile. According to the invention, the winding and setting is performed by means of a hood B, which carries a pinion E round with it, said pinion being in mesh with a fixed toothed ring G and a movable crown wheel D, so that the crown wheel D rotates with the hood B but at a different speed, and the setting is indicated by graduations on the lower edge of the hood B and by other graduations on the crown wheel visible through a window C in the hood. The hood is attached to a core member J provided with a central screw H, which is in engagement with a nut like member L projecting through slots in the core J, and bears at its inner and against a seat J<1> in the core, so that by turning the screw, the core J can be tightened against a conical seat K on the body of the fuze. The core J is connected at its inner end to the clockwork M. The clockwork is provided with a copper washer P, which is clamped against teeth Q on a fixed ring R by the set back of a ring N when the shot is fired, after which a centrifugal ball T moves out and prevents rebound of the ring N ; this arrangement retains the clockwork in its set position.

Title: Fabrication of carbon and graphite bodies
IPC: C04B35/66
Filed: 1961-06-29
Abstract: Carbon bodies are fabricated by forming carbonaceous mixtures into "green" bodies of the desired dimensions and then joining these "green" bodies together with a carbonaceous bonding agent, surrounding the joint with support tape to prevent escape of the bonding agent and heating the jointed pieces in a baking furnace. The bonding agent may be any suitable liquid or liquefiable carbonaceous material, for example a mixture of 15 to 85% coal tar pitch and 85 to 15% coal tar with a preferred composition of 35% coal tar pitch and 65% coal tar.  The tape is preferably an adhesive tape which can be carbonized or volatilized in the subsequent baking operation, but a support tape of sheet steel or aluminium can be used.  The joined pieces are preferably packed in the furnace with the joint horizontally disposed and submitted to an hydraulic pressure of 5 to 7 lbs. per sq. inch during the baking.  The carbon body formed is optionally graphitized.
