Title: Machine for injecting fluids into meat products
IPC: A23B4/02
Filed: 1974-08-05
Abstract: 1478182 Injecting meat TOWNSEND ENG CO 5 Aug 1974 [20 Aug 1973] 34417/74 Heading A2D A method of injecting fluid into a meat product comprises moving a meat product adjacent to and past a fluid injector needle means comprising a plurality of injector needles, stopping the movement of the meat product adjacent said fluid injector needle means, moving the fluid injector needle means so that the needles will penetrate the meat product, introducing fluid to said needles under pressure as the needles penetrate said meat whereby the fluid will be forced through the needles into the meat, sensing the average thickness of the meat, adjusting the time interval during which fluid is injected into the meat according to the average thickness of the meat whereby varying thicknesses of meat will be injected with different predetermined amounts of fluid. A machine for carrying out the above method, is shown in Fig. 1 and the thickness sensing portion of this machine shown in Fig. 4. The machine comprises a table 11 having a conveyor means 12 for moving meat product portions 38. A fluid manifold 20 is positioned above the conveyor means and secured to arms 14 and 16 (see also Fig. 2, not shown) which arms are pivotally connected at their other ends to table 11 for swinging movement about axis 17. Such movement is transmitted from a power source to arms 14 and 16 by rod 18. Fluid manifold 20 contains a plurality of injector needles 36, and is provided with a cover 40 which is connected to a valve means 46, itself connected to a fluid supply means via inlet 56. The valve means 46 contains valve member 72, which is provided with a shaft 76, which shaft is by the linkages illustrated in Fig. 5 (not shown) connected to an actuator arm 88. Arm 88 is at one of its ends connected to a meat thickness sensing means in the form of a stripper plate 120, and at its other end connected as illustrated in Fig. 5 to a cam plate 96 which plate is secured to a post 99 mounted on table 11. In operation, downward movement of arms 14 and 16 will bring the injector needles into contact with meat product 38. When stripper plate 120 contacts the upper surface of the product, cam roller 94 will cease to move in slot 100. Valve housing continues to move downward with the manifold 20 and arms 14, 16. This continued movement will rotate valve member 72 thereby opening discharge port 66. Hence fluid will be supplied under pressure to manifold, injection needles and meat product. Eventual upward movement of arms 14 and 16 will cut-off this supply of fluid. The amount of fluid injected into the meat product, is dependent upon the length of time valve 72 is open, which in turn is dependent upon the position of stripper plate 120 and roller 94.

A method of producing a hot plasma comprises introducing into a container deuterium or deuterium and tritium at a pressure of at least 1 mm. and preferably at least 10 mm., starting an electric discharge through the gas, and producing a magnetic field perpendicular to the direction of heat conduction in the transition space between the discharge and the wall of the container. In the apparatus shown the container comprises four sections, such as 11 and 12, joined together with insulation between each section to form a torus, and the container is surrounded by a cooling jacket 1, also formed of four insulated sections. Split rings 6 and 7 are arranged above and below the torus and a further split ring 10 surrounds the torus. In operation a capacitor bank 61 is discharged through these split rings to create a plasma ring 72 which is compressed by an axial magnetic field of up to 50,000 gauss produced by the coil 2 surrounding the torus. The gas pressure may be higher, by a factor up to 100, then the gas pressure is the space surrounding the discharge, the difference 'is pressure being balanced by magnetostatics pressure produced by the magnetic field. The axial magnetic field also reduces losses by heat conduction.

Abstract: 901,584. Hydraulic transmission of power; fluid - pressure servomotor - control systems. DOWTY ROTOL Ltd. Oct. 29, 1958 [Nov. 8, 1957], No. 34942/57. Classes 69 (2) and 135. A hydro-mechanical transmission comprising an hydraulic pump 10 having a rotatable cylinder block 13 and hydraulically-coupled to an hydraulic motor 23 having a similar rotatable cylinder block 24, includes control means adjustable during operation of the transmission to alter the amount of slip permitted between the rotatable cylinder blocks in response to speed error signals derived from a speed governor used for governing the speed of a rotary machine driven by the hydraulic motor in the sense to eliminate speed errors detected by the governor. The control means comprises a spool-type bleed valve 28 slidable in a cylinder 29 connected through annular chambers and passages 34, 35 with a pump outlet passage 20, and motor exhaust passage 25, respectively, and through passages 39, 40 and annular chambers with a cylinder 43 slidably mounting a spool-type control valve 44 connected to the output member of a relay 49. In use of the transmission, a governor (not shown) governs the speed of the prime mover driving the pump 10 to within, say, Œ 1% of selected speed and a further governor (not shown), e.g. an electronic governor, is driven by the motor 23, sensitive to within Œ 0.1% of correct motor speed and connected to the relay 49 to transmit a correction impulse dependent on the error. If, e.g., the electronic governor detects a small increase in motor speed, a corresponding signal is transmitted to the relay 49 to displace the control valve 44 rightwardly. This in turn upsets the balance in liquid pressure acting on the ends of the bleed valve 28 which moves leftwardly to increase the amount of opening of small ports 36 to bleed away liquid in the passage 20 to the exhaust passage 25 to reduce motor speed to the governed speed.

A heat-exchanger is made by coating a sheet 1 with a stop-off slurry 5 containing water and a metal oxide, superimposing a sheet 3 on the sheet 1 with the slurry trapped therebetween, bonding the sheets together and heating them in a reducing atmosphere penetratable through at least one of the sheets to reduce the oxide and release a gas which inflates at least one of the sheets over the coated area. The sheets 1, 3 may be steel and the slurry is preferably iron oxide and water applied to the sheet by silkscreening, stencil spraying etc. The slurry may be applied to both sheets either as a mirror image or co-operating parts. The superimposed sheets 1, 3 are bonded together by rolling and sintering in an inert atmosphere, e.g. nitrogen and the composite heated in an atmosphere of hydrogen or dissociated ammonia for approximately 10 minutes at 1800‹ F. The hydrogen rich atmosphere diffuses through the sheets and reduces the iron oxide to iron. The steam produced in the enclosed shape inflates the sheets over the area of the slurry. If the sheets are not of equal thickness the pressure build up inflates, the thinner sheet. Zinc oxide, zinc carbonate, copper oxide, graphite or cellulose may be mixed into the slurry in which case the tube is coated internally with zinc, copper or carbon. If it is desired to bond and inflate a pair of sheets which form a brittle bond when bonded together, e.g. copper and aluminium or aluminium and zinc, two sheets of stainless steel are inserted between the pair the inflation being between the stainless steel sheets. The composite may be used in a switching device (see Division G1).

Atmospheris, eliminiating or limiting; thermionic valves, arrangements of. - Comprises a system of thermionic valves excited and coupled back to a mistuned wireless receiving circuit in such a way as to reduce the effect of shock-excitation due to atmospherics while amplifying the effect of waves of desired frequency. The receiving-circuit 1, 2, which contains a variable resistance 3 and may be the antenna circuit, is connected through an amplifier 21 to a detector 22. In order to destroy the effect of atmospherics, a further system of valves 4, 5, 6, 7, 8 is connected to the receiving circuit and is tuned to a frequency different from that of the received signals. The transformer 12 is so arranged that the oscillatory currents of the valves 7, 8 are opposite in phase, that of the valve 7 being of slightly greater strength. The algebraic sum of these two currents is led through the back-coupling 13 with the object of neutralizing the atmospherics and amplifying the signal. The valve-system described may alternatively form part of the ordinary re ceiving system.

Title: Spinning regenerated cellulose filaments of a denier below 0.5
IPC: D01F2/06
Filed: 1957-11-11
Abstract: Regenerated cellulose filaments of less than 0,5 denier are made by extruding viscose through spinnerets, the orifices of which do not exceed 0,002 inch in diameter, into a coagulating bath maintained at a pH above 4 and preferably above 6, applying to the extruded filaments a "jet stretch factor" of at least 4, passing the filaments through a strongly acid regenerating bath of low pH, and collecting the filaments, the strength of the coagulating bath being adjusted with respect to the salt test of the viscose used so that the filaments are only coagulated sufficiently to prevent them from adhering to each other on leaving the bath.  The "jet stetch factor" is defined as the ratio of the velocity of the yarn as drawn from the coagulating bath on to the first godet to the velocity of the viscose passing through the spinneret orifices.  The ratio may be up to 10 or even more, as compared to ratios of about 0,3-1,5 used in conventional viscose spinning.  Low spinning speeds not exceeding about 20 metres per minute are preferably used.  In an example, viscose containing 7,4% of cellulose, 6,6% of sodium hydroxide, and 36% of carbon disulphide based on cellulose, and having a sodium chloride salt test value of 4,5, is spun through a jet having 0,002-inch diameter holes into a bath containing 8% of sodium sulphate and a mixture of mono-, di- and tri-sodium phosphates in a total amount of 7,7% calculated as trivalent phosphate ion, and having a pH of 7,5 and a temperature of about 40 DEG C.  The filaments pass through this bath a distance of 20 inches and thence to a godet wheel having a peripheral speed of 11,4 metres per minute. The jet stretch ratio is about 6,3 : 1.  The yarn then passes through a regenerating bath at about 70 DEG C. containing about 10% of sulphuric acid, about 20% of sodium sulphate, and a small proportion of phosphoric acid.  From the regenerating bath the yarn passes to a pair of godets having a peripheral speed of 20 metres per minute and is then washed and collected in a centrifugal spinning box.  Its denier per filament is about 0,14.  Numerous coagulating bath compositions and components are specified, the latter including formic, acetic and propionic acids, methanol, ethanol, dioxane, ethylene glycol, and acetone.
