Title: Frozen food patties and method of preparing same
IPC: A23L13/50
Filed: 1957-06-18
Abstract: Frozen food products e.g. patties, to be cooked for consumption are made by mixing food particles with a non-gelled aqueous solution of an edible colloid which forms solutions that gel on heating and which gel-forming characteristics are not affected by freezing and subsequent thawing, to provide a cooking and binding medium for the particles, and freezing the admixture whereby the food particles are initially held together by the frozen colloid solution.  Cellulose methyl ethers (marketed under the trade name of "Methocel") consisting of long-chain cellulosic polymers having a methoxyl content of about 27,5 to 32% are specified; carboxymethyl cellulose is stated to be unsuitable.  Raw or cooked meat, sea food, vegetables fruit, rice and nuts may be included in the product.  According to an example, 100 lbs. raw, ground hamburger meat was mixed with 20 lbs. of a water solution containing 0,25% "Methocel" having a viscosity of 4000 cps. in 2% solution at room temperature, 20 lbs. whole peas were added to the mixture, and the resulting mass was placed in a stuffing machine and extruded into elongated metal moulds of 4 1/2 inch diam. The mass in the metal moulds was then hard-frozen, sliced into 1/4 inch patties and packaged as a frozen food product.  In further examples, the concentration of the colloid solution was increased to 2,0%.  The food products in other examples were respectively based on raw turkey or chicken, whole shrimp mixed with buttered, precooked rice, mixed raw vegetables, and a mixture of fruit, raisins, sugar and nuts.

Title: Textile spinning device
IPC: D01H4/10
Filed: 1963-05-15
Abstract: 979, 930. Textile spinning. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. May 15, 1963 [May 25, 1962], No. 19194/63. Heading D1D. A method of spinning comprises shredding a sliver by exposing it to an airstream, projecting the fibres on to a receiving surface and moving the end of a yarn relative to and drawing it away from the said surface whereby the yarn picks up fibres and grows continuously. In the form shown a sliver 10 fed from rollers 11, 12 (which may be the output rollers of a roving frame) passes through a stationary tube 2 to a smooth walled, circular cavity in a rotor 3. The rotor, mounted on a stationary outlet tube 4 and driven by a belt 21 has orifices 24, 25 near the outside of the cavity and thus acts as an air pump, air being drawn in through the tubes 2, 4 and ejected from the orifices 24, 25. The stream of air passing down tube 2 shreads the sliver 10 the fibres of which are then flung to the outermost diameter of the cavity where they are evenly laid. These'films are then continuously picked up by the end of the yarn 30 leaving the cavity via the tube 4 and delivery rollers 5, 6. The counterflowing streams of air from tubes 2, 4 create a boundary which derides the cavity into volumes A and B so that the loose fibres in volume A are held separate from the yarn in volume B. A further embodiment is described wherein the outer surface 14 of the cavity is not curved but is formed of oppositely tapering cones. Relative dimensions of the elements of the apparatus and details of the priming or starting up procedure are given.

Title: Improvements relating to apparatus for controlling and regulating gas supply for certain purposes
IPC: F02D9/02
Filed: 1922-07-13
Abstract: 205,200. Clarke, T. July 13, 1922. Electrically-actuated valves. - A valve apparatus, particularly adapted ior use in connection with the treatment of flour with chlorine as described in Specification 165,149, [Class 58, Grain &c.), comprises a valve actuated by a solenoid controlled by a switch operated by the torque transmitted to the apparatus. While full power is being transmitted to the apparatus the solenoid a<1> is energized to hold the core b against an adjustable stop y and maintain the valve s open against the action of an adjustable loading spring t. When the power falls to a predetermined fraction of the maximum the torque switch short circuits the solenoid and permits the spring to close the valve. The inlet has constricted passage u and the outlet has a gauge x to give an indication of the rate of flow. The pulley a is mounted on the driven shaft b so as to have a slight angular movement and when running light power is transmitted through a stop d on the pulley and spring j acting on an arm e on the shaft. In these circumstances an insulated contact o on an extension g of the arm engages a hinged contact q on the pulley and so completes a circuit through slip rings and bushes t to short circuit the solenoid. When full power is being transmitted the spring is compressed allowing the stop d to engage a stop h and the contacts o, q to separate. In this position the contact q is held by a spring against a stop r. According to the Provisional Specification the two contacts engage when full power is being transmitted.

Title: Improvements in or relating to the demodulation of pulse-position-modulated signals
IPC: H03K9/04
Filed: 1962-05-22
Abstract: 985,828. Pulse modulation; transistor circuits; automatic frequency control systems. MARTIN-MARIETTA CORPORATION. May 22, 1962 [June 29, 1961], No. 19633/62. Headings H3A, H3T and H4L. A demodulator for phase-modulated pulses comprises a sawtooth waveform generator operating approximately at the average repetition frequency of the incoming phase-modulated pulses, and a circuit for sampling the amplitude of the waveform from the generator at times determined by the modulation of the pulses to produce an output signal varying correspondingly in amplitude, a selected portion of this output signal being used for synchronizing the waveform generator with the average pulse repetition frequency of the phase-modulated pulses. As shown, the waveform generator comprises an oscillator 100 whose frequency is controlled via lead 127 and voltage-variable capacitors 102. The oscillator output is converted into negative-going square waves by a Schmitt trigger 101 which are applied to the base of transistor 106 in the sawtooth generator 104. Capacitor 109 is charged to a negative value through a constant current source formed by transistor 110 and the application of a negative pulse to transistor 106 causes capacitor 109 to discharge rapidly through diode 128. The resulting sawtooth wave is supplied via an emitter-follower 111 to a sampling circuit 113 including four diodes 114, which in the absence of an incoming signal block the sawtooth wave, the diodes being back-biased by a residual charge on capacitors 114a, 114b due to the previous pulse signal. The phase-modulated pulses are supplied to the base of transistor 117 and coupled via transformer 118 to the diodes 114 to cause them to conduct and allow the sawtooth wave to charge the capacitor 119. Thus the sampling circuit produces a stepped wave output whose amplitude varies in accordance with the pulse modulation. This output is supplied to an emitter-follower circuit 120 in which the emitter of transistor 121 is coupled to the base of transistor 122 to obtain a high impedance input and the output of transistor amplifier 123 is fed back via capacitor 124 to the collector of transistor 121 to further increase the input impedance. In this way the high output impedance of the sampling circuit 113 is coupled to the low impedance of a bandpass filter 125 which smoothes out the stepped wave for utilization. A low-pass filter 103 passes the direct current component of the output signal to control the oscillator 100.
