Filed: 1976-02-10
Abstract: 1482065 Shaped starchy foodstuffs GENERAL FOODS CORP 10 Feb 1976 [10 Feb 1975] 05227/76 Heading A2B A shaped starchy foodstuff is made by rehydrating a dry particulate starchy foodstuff e.g. potato, rice, macaroni, wherein 80% of the particles have a size greater than 40 mesh U.S. standard and using tapioca starch as a binder. The tapioca starch may be ungelatinised, in which case it is mixed with the starchy foodstuff either before or after rehydration in quantity such that the final shaped foodstuff contains 5-20% tapioca starch, and is then partially gelatinised before shaping by heating to at least 125‹F. Alternatively pregelatinised tapioca starch modified by clearing the starch granules may be used, in a quantity of 1-15%. The shaped foodstuff may be frozen, optionally after deep-fat frying. Shaping may be carried out at 32-150‹F. Onions, eggs, butter, cheese, tomatoes and sour cream may also be included.

Title: Improvements in or relating to electric pulse modulators
Inventor: FLOWERS THOMAS HAROLD
IPC: H04J3/04
Filed: 1950-03-03
Abstract: 707,384. Electric distributers. POSTMASTER GENERAL. Feb. 28, 1951 [March 3, 1950], No. 5480/50. Class 40 (3). [Also in Group XL(c)] In an n-channel multiplex pulse distributer and modulator, n being the product of two or more relatively prime integers, there is a group of pulse sources for each integer, the number of sources being equal to the integer and having a recurrence frequency inversely proportional to the integer, while the trains of each group are regularly intercalated and when a pulse occurs in one group, a pulse occurs simultaneously in all the groups. In one embodiment, the group of eleven pulse trains a1 ... a11, Fig. 1, and the group of ten pulse trains b1 ... b10, having a recurrence period of ten-elevenths of that of the a pulse trains, are generated by the arrangement described in Specification 707,401, [Group XL(c)], enabling 110 interlaced pulse channels to be used. The gating circuits, producing amplitude modulated pulses for six of the channels, are shown in Fig. 3. These channels 1x1, 1x2, 1x11 and 2x1, 2x2, 2x11 are the first, second and eleventh of the first and second respectively, of the ten groups. Each signal such as 1x1 is applied to the junction of a series-connected pair of rectifiers W1, W2, the other side of W1 being earthed and the other side of W2 being connected to a group channel yl. Bias current is fed to the junction from a source -V over resistance 3R1 and pulse current over resistance 3R2 from the appropriate a pulse train a1 . . .a11. In the absence of a pulse, W1 is conducting, but in the presence of a positive pulse it becomes non-conducting and W2 conducts, connecting channel 1x1 to the common y1. The ten second group gating stages y1, y2, &c. are similar to the first stages but are fed with pulse trains b1, b2, &c. so that each of the 110 channels is connected in turn in cyclic order to the common output channel z. In a second embodiment, Fig. 4 (not shown), 110 single-stage gating circuits are provided which are each fed with a different combination of one of each of the a and b pulse trains and conduct only when pulses from each train occur simultaneously. Alternatively three or more gating stages may be provided. For example, a 105-channel system may be controlled by fifteen pulse sources in three groups of seven, five and three pulse sources respectively. These may be supplied to three stages in series or in one stage per channel using combinations of the pulses, or in two series stages one using pulse combinations from two of the pulse groups. Specification 707,379, [Group XL(c)], also is referred to.

Title: Improvements in or relating to reciprocating movement synchronous compressors
Inventor: REUTTER JEAN LEON
IPC: F04B35/04
Filed: 1960-02-16
Abstract: 882,965. Reciprocating motors. USINES CHAUSSON S.A. DES. Feb. 16, 1960, No. 5490/60. Class 35. [Also in Groups XXVIII and XXXII] A reciprocating compressor motor, e.g. for a refrigerator, comprises two opposed permanent magnets 6, 7 constrained by springs 11, 12 and slidable within a substantially tubular magnetic core 4 which has an A.C. energizing coil 5 of the same width as a magnetic portion 9 that separates the magnets. The magnets have polepieces 8, 10 and the core has a non-magnetic liner 15. The core may be either solid or consist of axial laminations which may be spaced around the liner in four groups (Figs. 2 and 3, not shown). In one embodiment (Fig. 1, not shown), the armature assembly has a singleacting compressor, comprising a flexible cup piston in a cylinder, connected to each end and the springs are undertuned so that the resilient effect of the compressors brings the assembly to resonance at the A.C. supply frequency when on load. If the magnitude of the oscillations becomes excessive the compressor pistons strike spring-loaded flap valves which act as buffers. The device is enclosed in a casing to which the fluid is admitted at low pressure. In an alternative arrangement, Fig. 4, a double-acting compressor is fitted at one end only and exhausts within the casing 1 which thus contains fluid at a high pressure. The other end of the armature is connected to a piston 31 which operates in a virtually closed cylinder 24 and acts as an additional spring. The cylinder is connected to the inlet 2 via a small bore tube 32, and as the inlet pressure, and hence the pressure within the cylinder 24, decreases the effect of this " spring " is lessened and so is the natural frequency of vibration of the assembly. This was arranged to be above the supply frequency in this case, so it now gets closer to it and the amplitude of vibration increases; when great enough, valves 27, 28 are opened by the piston 31, high pressure fluid is admitted and the amplitude begins to drop. In practice the amplitude is thus maintained substantially constant regardless of the compression rate. The effect may be enhanced by an additional pump (Fig. 5, not shown) to exhaust the cylinder 24.
