Title: Method of covering foodstuffs
IPC: A23L1/00
Filed: 1953-01-16
Abstract: Foods, exemplified by margarine, butter, cheese, meat, meat products, sausages, and bread, are given airtight coverings by dipping in, spraying with, or otherwise coating with a aqueous synthetic resin dispersion containing pectin as a plasticizer. The pectin is preferably used in conjunction with glyceryl triacetate as a solvent; a preparation containing glyceryl triacetate may be diluted with glycerol.  Transparency of the coating may be modified by inclusion in the dispersion of a filler, e.g. starch, a hemicellulose, a cellulose ester or a cellulose ether; a colour may be incorporated to safeguard the food against undesirable effects of light.  An example is the formulation of an aqueous dispersion of polyvinyl acetate, carboxymethylcellulose solution, starch, and a plasticizer made up of citrus pectin, glyceryl triacetate, glycerol, carboxymethylcellulose, water and castor oil.

Filed: 1941-02-04
Abstract: 548,826. Testing the balance of rotary bodies. UNITED GAS INDUSTRIES, Ltd., and ANGOLD, E. B. Feb. 4, 1941, No. 1469. [Class 106 (ii)] The body 1 to be dynamically balanced, e.g. the rotor of a gyroscope, is mounted in bearings suspended for limited freedom of movement in planes normal to the axis of rotation of the body, and provided with an axially disposed indicating element 15 having a determined natural frequency of vibration, the body being rotated at a speed corresponding to this frequency and the indicating element observed through a stroboscope 27. The rotor 1 is provided with bores 2 arranged at 120 degrees the bores at opposite ends being separated by a partition 3 through which screws 5 for balancing are threaded, extensions 6 being provided for nipping off. The rotor is first statically balanced by supporting the rotor journals on parallel rails and slightly rocking the rotor. The heavy spot rolls to the bottom and some of the extensions 6 may be nipped off to statically balanced the rotor. For dynamic balancing the rotor is mounted with its journals in V-blocks carried by a U-cradle 9 supported by springs 19 from columns 20 mounted on a base 21 provided with an adjustable ball and sprocket support 22 to ensure that the axis of the rotor is horizontal. Rods 14, 17 are mounted in the axis of the rotor the rod 14 having attached thereto a spring steel wire 15 ending in a knob 16 while the rod 17 carries a balancing weight 18. The element 15 is viewed from an axial position through a stroboscope comprising a cylinder 24 having a horizontal spindle normal to the axis of the rotor spindle 7 and provided with a wide diametric slot 25. The spindle of the cylinder 24 is rotated at a speed which is half of that at which the rotor is driven. The slot is subdivided by plates 26. The cylinder is arranged in a casing having an eyepiece 28 and a sighting tube 29 with a transparent slide 30 having a spider web graduation. The rotor is driven by an air jet directed on the usual cups on the rotor provided for the normal drive. The rotor is speeded up to resonance with element 15 and when there is lack of balance, the head 16 describes a circle of a diameter depending on the out of balance. If viewed through the stroboscope, the element appears as a stationary pointer at an angle which may be referred to a marking such as 33 on the face of the rotor, the length of the apparent pointer indicating the degree of out-of-balance. The screws 5 are then moved to effect balance.

Void [Published under Sect. 91 of the Acts]. Drawings to Specification. [Class 40 (ii).] A pile of disc records of different sizes in a stationary magazine are released singly from the bottom and received by grab devices which lower them on to a device which rotates them for playing. After one side of the record has been played the grabs again engage the record to turn it over for playing the other side, after which the grabs re-engage and lower the record to a magazine below. Each magazine includes a tube engaging a central aperture in the records, and the pile in the upper magazine is supported on segmental plates projecting through the central tube and operable by withdrawal and vertical movement of some of these to separate the bottom record from the remainder so that it can be engaged by the jaws of the grabs. The grabs now descend with the record to deposit it on a series of radially arranged conical driven rolls by which the record is rotated for playing. When one side is played the grabs re-engage, the reproducer is lifted and swung clear, and the driving rolls which are supported at their outer ends on pivots are lowered into a vertical position to permit of the record being turned over by the grabs. The driving rolls now swing up into driving position and the reverse side of the record is played, after which the driving rolls again move back to permit the grabs to lower the played record into the bottom magazine. The grab jaws have central cores which by engagement with the edge of the record operate to control the interaction of the parts. The arrangement described with reference to the drawings filed is not described clearly.

Abstract: 448,716. Valve circuits for wireless reception. COLE, Ltd., E. K., Priory Crescent, Southend-on-Sea, and MARTIN, A. W., 1, Thames Close, Leigh-on-Sea. Jan. 23, 1935, No. 2191. [Class 40 (v)] To reduce interference from undesired stations the fidelity of reproduction of a radio receiver is automatically controlled in dependence on the field strength of stations adjacent in frequency to that being received. The Figure shows a superheterodyne receiver in which the intermediate frequency circuit 2 of the frequency changer V0 is coupled to two circuits 4, 5 tuned respectively 9 k.c. above and 9 k.c. below the intermediate frequency and coupled to valves V1, V2, the outputs of which are rectified by diodes 8, 9. The common point of the diode load resistances 10, 11 is connected to the grids of V1, V2 through resistances 13, 14. The potential at which the diodes come into operation is governed by the tapping point connecting the diode cathodes to potentiometer 15. When a strong interfering signal is received, circuit 4 or 5 is energized, the rectified potential across resistance 10 or 11 being applied to the control grid of V1 or V2 to vary its bias. The resulting change in anode current varies the cathode potential by varying the voltage drop across resistance 16; the potential of the cathode of V3 changes similarly, thereby varying the audio frequency response of the receiver by varying the shunting effect of the valve V3 which acts as a variable capacity across a low frequency stage.
