Title: Apparatus for vulcanizing endless belts
IPC: B29C35/02
Filed: 1971-09-20
Abstract: 1341773 Moulding belts B F GOODRICH CO 20 Sept 1971 [21 Sept 1970] 43749/71 Heading B5A In an apparatus for vulcanizing a plurality of endless elastomeric belts, such belts are passed simultaneously over a heated rotary drum 20 having a plurality of circumferential, axially spaced moulding recesses to receive such belts, one for each recess, and each belt is individually tensioned whilst in contact with the drum and compressed by one of a plurality of endless bands 40, e.g. of metal passing around idler pulleys 41-43 each being grooved circumferentially to receive the bands. Each belt passes around a pulley ring 32 and an idler pulley P. The pulley ring assembly is mounted on a subframe 28 movable on rods 26 by a toggle mechanism so that it can move towards or away from the curing drum. Each ring 32 is carried on a non-rotary disc slidable horizontally on a support and moved towards or away from the drum by a fluid motor, all the fluid motors being connected to a common fluid pressure manifold. Thus each ring is individually urged against its belt independently of the others to effect uniform belt tensioning. The bands 40, which are similarly individually tensioned by an assembly of pulleys 41, are brought into engagement with a part of the drum periphery when the pulleys 42, 43 are brought close to the drum. The pulleys are rotatably mounted at the ends of pairs of arms 44, 55 pivoted at 51 and 56 respectively and interengaged by a pin 54 on the arms 44 engaging within a bifurcated portion 55a of the arms 55. When the pivot pin 51 is manually turned by a crank 53 the pulleys 42, 43 are either brought into close proximity to the drum or are spaced therefrom. In the former position the pulleys are held by a locking bar 57 which is secured to the arms 44 and pivotable into engagement with the machine frame. A heat insulated shoe comprising arcuate sectors 60a, 60b connected to arms 44, 55 is brought close to the endless bands 60 when they are tensioned against the drum. The latter comprises a number of interengaged arcuate segments with one or more chambers for the recep - tion of heating or cooling fluid supplied thereto via a rotary valve coaxial with the drum and arranged so that whilst the greater periphery of the drum is heated a smaller segment is chilled so that a belt leaving the influence of the compression bands is cooled.

Abstract: 1,100,325. Discharge tubes. VEB WERK FUR FERNSEHELEKTRONIK. 21 Oct., 1965, No. 44587/65. Heading HID. A gas discharge power switching tube includes both a control grid and an auxiliary apertured disc anode positioned between the control grid and the cathode, a glow discharge being maintained between the cathode and the auxiliary anode to facilitate ignition, and the penetration into the grid/anode space of the plasma of evaporated cathode material formed near the cathode during the arc discharge being minimized, with consequent increase in the controllability of re-ignition, by ensuring that the grid/cathode spacing exceeds a given value determined by the gas pressure, and by the relative staggering of the apertures in the control grid and the auxiliary anode. The tube contains xenon at a pressure of 40 torr., the cathode 4 containing an emissive mixture of 60% tungsten powder and 40% barium aluminate, and the apertures in the auxiliary anode 6 and the control grid 3 being staggered by relative rotation of the two electrodes. The product of the gas pressure and the auxiliary anode/grid spacing lies in the range 7-12 cm. torr., and the grid 3 may be made sufficiently thick, e.g. such that the product of gas pressure and grid thickness lies in the range 1-3 cm. torr., to reduce electron penetration from the auxiliary discharge into the grid/anode space during the off periods.

Abstract: 459,829. Cooling bread. FARRER, J. 0., 27, Chancery Lane, London.-(Fleisher, W. L.; 11, West 42nd Street, New York, U.S.A.) May 16, 1936, No. 13974. [Class 29] [See also Group VI] Freshly baked bread is first cooled under atmospheric pressure until it attains a cellular structure o sufficient strength to withstand without rupturing a vacuum of approximately 26 inches or more an( is then cooled by evaporation of moisture therefrom at sub-atmospheric pressure. For example loaves are carried on a conveyer through a chamber where they cool under atmospheric pressure to the vacuum cooler 12. Each loaf 16 rests on a plate 13 on the conveyer, and a measured quantity of water is discharged on the plate as it reaches the vacuum apparatus. This apparatus comprises a member rotating about a vertical axis and having recesses 15 in its lower surface communicating with a vacuum pump 27 through a distributer 19 with ports 23. The conveyer passes under one part of the rotating member and a plunger lifts the loaf into a depression. This particular depression at this point is in communication with the vacuum pump, and the plate 13 is held on to the member by the atmospheric pressure for a sufficient period for the loaf to cool. The distributer then cuts off the pump connection and the loaf and plate fall into a collector. The member 12 may alternatively rotate around a horizontal axis, the depressions being directed radially outwards. Alternatively loaves partially cooled in the atmosphere may pass through an air lock 109 to vacuum chambers 132, 134, &c. containing conveyers 137. Hollow needles 112 and 112a are provided which may be thrust into passing loaves and substances are injected therethrough into the bread. The substances mentioned are lemon, orange, or raisin flavouring, colouring matter, butterfat, vitamin preparations, or gases such as ozone.

Title: Process and device for the portioning out and packing of fish fillets in small packets
IPC: B65B25/06
Filed: 1964-11-18
Abstract: 1,058,179. Packaging. H. BAREZ, and F. FLOR. Nov. 18, 1964 [Nov. 20, 1963], No- 47010/64. Heading B8C. A process for packing fish fillets prior to deep freezing consists of filling with the fillets a pressing chamber, the cross-section of which is greater than that of the desired packet, the chamber being completely enclosed and the fillets being pressed into a pressing channel with gradual diminution of the cross-section and thus formed into a strip of the crosssection of the desired packet, whereupon a packet length is cut off and packed. Washed fish fillets are conveyed to a trough 3 into which they are packed by hand with their tails directed towards the pressing channel 7. After filling the trough to a predetermined level, a gate 4 is opened allowing the fillets to drop into a pressing chamber 5 of cross-section similar to, but larger than, that of the desired packet. The gate 4 is closed, and the fillets are pressed through channel 7 by a plunger 6 having a spring-mounted working face 22 thereon into a unit 9, there being a knife 8 at the end of the channel 7. Entry of the compressed fillets into the unit 9 pushes forward the preceding cut-off portion into one of two chambers 25a, 25b of an oscillatable carrier 10. Ejection plungers 14 and packet transporting conveyers 15 are provided on each side of a support 24, only one set being shown in Fig. 4. As the fillet portion enters a carrier chamber it engages a feeder 13 which causes the knife 8 to cut off the next portion and which initiates the movement of the carrier 10 to one side. Simultaneously, the plunger 14 ejects the preceding portion from the other chamber into a packet 16 on a conveyer 15. In place of the loading trough, a second pressing chamber may be provided alongside the chamber 5, both being movable across the direction of compression and being actuated by one working piston. The chamber 5 may have a circular cross-section. The parts 7, 9, 10 can be interchanged with similar parts per packets of different sizes.
