Title: Oscillographs
Inventor: SEIDEL JOACHIM
IPC: G01R13/04
Filed: 1969-10-30
Abstract: 1,268,256. Determining amplitude and phase of electric signals. J. SEIDEL. Oct. 30, 1969 [Oct. 31, 1968], No. 53170/69. Headings G1Q and G1U. An oscillograph for displaying the waveform of an A.C. signal incorporates a magic band type electron beam tuning indicator tube to which the signal is applied, together with a mechanically driven dissecting arrangement for enabling length of the light band of the tube to be displayed as a function of time, the dissecting arrangement consisting of a slotted member with equally spaced narrow slots extending in the direction of change of the light band. The arrangement is driven such that the direction of movement of the slots is perpendicular to the direction of change in length of the light band. The slot spacing may be the same as, or larger or smaller than, the width of the tube. The arrangement consists of a slotted cylinder in which the magic band tube is accomodated. To show oscillograms of two voltages, the arrangement may have two rows of equally spaced slots, each passing along a respective part of a twopart light band. The slots of the two rows are relatively offset by half the spacing between adjacent slots, which is twice the width of the light band. The electron beam tube is supplied with the two voltages in an alternating rhythm such that the oscillograms of the two voltages are separately registered by the upper and lower halves of the light band. The arrangement may be used to display Lissajous figures by periodically reciprocating a single slot in front of the light band, e.g. by means of spring induced torsional vibrations or a rotating shaft and eccentric. To display the output from e. g. a model generator, the generator may be driven by a motor which also drives the slotted arrangement of the oscillograph, the generator output being applied to the magic band tube. In an arrangement for determining phase difference between two alternating voltages applied to the oscillograph, the slotted arrangement is driven by a synchronous motor with a rotatable casing, which enables the oscillogram to be laterally displaced. The motor is rotated so that a characteristic point of one oscillogram aligns with a vertical graduation and then so that an equivalent point of the second oscillogram makes the same alignment. The difference in rotation gives the required phase difference.

Title: Improvements in or relating to methods of and apparatus for treating meat, and meat so treated
Inventor: MCCARTHY ROBERT
IPC: A23L5/20
Filed: 1969-11-03
Abstract: 1,253,318. Meat treatment. EEFP CORP. 3 Nov., 1969, No. 53685/69. Headings A2D and A2E. A method of treating meat comprises introducing a gaseous palatable pressurized fluid, for example steam, into pieces of uncooked meat so as to raise the pressure in and on the pieces to partially disrupt the structural balance of the meat tissues without cooking said pieces, discontinuing the pressurized gaseous fluid introduction, and releasing the gases and any vapours from around the meat pieces so that undesirable liquid substances in the meat pieces which are at an elevated pressure, will burst through the meat tissues thus causing a breakdown of said tissues and rendering undesirable substances amenable to extraction in fluid form. The meat pieces are then subjected to a source of vacuum so that liquids in the meat are extracted, this extraction causing an additional breakdown of tissue. The meat, treated in the above manner, may then be cooked. The above treatment may be carried out on meat pieces placed in an open container, which after the treatment may be sealed and sterilized. A suitable apparatus for carrying out the steam injection process is shown in Fig. 3 wherein a can C of meat M is held by a jack 30 up against a steam injection head 32. With the valve plug 44 in the position shown, steam is passed through the head and into the can via the foraminous outlet plate 48. The head is provided with vent openings 50 to allow the passage of exhaust vapours and gases. Movement of the valve plug 44 to the position of Fig. 4 (not shown) will terminate steam injection and allow the pressure in the meat and container to fall. Liquids in the meat pieces will thus burst through the meat tissue. The can is then transferred to an extraction device, shown in Fig. 5, wherein utilising cam device CR the can is raised and contacted with the gasket 68 to form an air tight seal (Fig. 6, not shown). Vacuum is applied by rotating turret assembly T until the head H co-operates with an opening 86 in the supporting hub 60 (Fig. 7, not shown). Further rotation of T will terminate vacuum treatment and the can may then be sealed and sterilized in known manner. The treatment is particularly applicable to tuna meat and salmon.

Abstract: 1334057 Load-responsive braking KNORRBREMSE GmbH 13 Nov 1970 [14 Nov 1969] 54269/70 Addition to 1280685 Heading F2F In a railway vehicle load sensitive device the pressure in a chamber 26 which is connected by way of a bore 56 and a connection 57 with an air conduit to a braking device is varied in direct response to the weight of the vehicle body 1. When the weight of the vehicle body 1 is increased a supporting element 18 presses with increased force against a single port or multiport elastic member 22 which thereby moves a double piston 21, 24, a diaphragm 17 being held in contact with the piston 24. Movement of the pistons 21, 24 causes movement of a plunger 38 against the bias of a spring 51, the plunger 38 having a widened foot portion 39 bearing on the diaphragm 17. Movement of the plunger 38 causes a valve plate 48 of a cylindrical guide port 47 to move off an annular shoulder 49 of a valve housing 40 against the bias of a spring 46. When this happens, air can flow through bores 52, 53 and through the valve housing 40 into the chamber 26. As the pressure increases in the chamber 26 the double piston 21, 24 is displaced to allow valve 48, 49 to be closed and the pressure in the chamber 26 is increased in accordance with the increase in vehicle weight. When the weight of the vehicle body 1 is reduced the plunger 38 moves away from the valve plate 48 and air from the chamber 26 flows through the valve housing 40 into a bore 48 in the port 47 and thence via a chamber 37<SP>1</SP> and a bore 36<SP>1</SP> to atmosphere. As the pressure decreases in the chamber 36 the double piston 21, 24 moves to close the valve 48, 38<SP>1</SP>. The supporting element 18 is movable in piston-like manner within a housing 16 which is fixed to a cross-member 7 which together with a frame (not shown) forms a bogie 3 of the vehicle. A ball 2 of a swivel bearing is mounted in a part-spherical recess 4 in the supporting element 18. A clearance s is provided between a flange 10 of the supporting element 18 and a rim 8 of the housing 16 which rim 8 acts to limit the travel of the supporting element 18 when the vehicle load is elevated beyond a certain level and sealing elements 11, 12 are provided between the parts 16, 18. As shown the elastic member 22 comprises a rubber disc but it may also consist of a cylindrical rubber member engaging with play in a rubber ring between the part 18 and the piston 21, the ring and the member being of different thicknesses and elasticities.
