Title: Improvements in temperature sensor system
IPC: H05B3/34
Filed: 1964-04-08
Abstract: 1,031,857. Control systems for resistance heaters. GENERAL ELECTRIC CO. April 8, 1964 [April 30, 1963], No. 14558/64. Heading H2H. An electric blanket controlled normally by a thermal cycling switch 14 has an over-temperature device comprising a relay coil 118 shunted both by a diode 117 to produce unidirectional current in the coil and by a thermally responsive element 120 which shunts windings 121, 122 and hence the relay coil at high temperatures, thus causing a contact 115 to open the circuit. A resetting switch 28 is linked with another switch 30 to foil continued operation with the switch 28 jammed closed. The diode 117 may be replaced by a diode bridge to pass pure A.C. through the element 120 or alternatively a resistor shunted by a diode oppositely poled to diode 117 may be connected in series with the coil. A stop switch 31 is included in the circuit. The relay may be arranged to be selfresetting.

Title: New or improved method of preparing meat or fish packed in sealed containers
IPC: A23B4/005
Filed: 1937-05-29
Abstract: In packing meat, including butcher's meat, poultry, game and fish, in sealed containers, meat is finely divided, mixed with farinaceous material, e.g. potato or other flour, or bread, rusks &c., and the mixture cooked, allowed to cool and divided into pieces or slices of substantial size which are filled into a container together with pieces or slices of other meat similarly prepared or with coarsely chopped or sliced meat of the same or different kind.  The container is then heated to processing temperature, causing the pieces of meat to unite to a coherent body, the container being sealed before during or after the processing.  Gelatine or other liquid which sets on cooling may be added to fill up spaces in the container.  A compound roll may be obtained by employing the pieces of the prepared finely divided meat as lining in the container which is then filled with the coarsely chopped or sliced meat which forms the core, or conversely. The core or shell of finely divided meat may be formed of discrete portions prepared from different kinds of meat. An additional shell or shells of finely divided meat of another kind or kinds may be inserted between the shell and the core.  The shell may not completely surround the core.  In preparing the finely divided meat there may be added, besides the farinaceous material, setting agents such as gelatine, seasonings, including spices, herbs, onions, tomatoes or eggs, and edible colouring matters.  Each meat used may be associated with a suitable flavouring material, e.g. pork with sage and onions, beef with tomato, and lamb with peas. Specifications 341,760, 377,766, 435,373, and 442,644 are referred to.

Filed: 1957-05-10
Abstract: 807,669. Drying grain. BRONSWERK, N. V. May 10, 1957 [May 17, 1956], No. 14967/57. Class 34(2) Granular material is dried by passing through a tube in contact with a heated gas flow, the tube having a vibrating floor which throws the coarser particles into the boundary layer only of the gas flow, while the finer particles are thrown into the faster moving gas where they acquire a greater speed. Consequently the coarser particles remain longer in the drying medium and more uniform drying is achieved. In one embodiment, air is blown by fan 1 through a heater 2 to a tube 4 into which grain is fed from a hopper 7. The tube is supported by springs 5 and is oscillated by a vibrator 6 in the direction shown by the arrows the movement being permitted by flexible couplings 3a, 3b. A separator 9 discharges the material at its outlet 11 and the drying gas leaving its outlet 10 may be returned to the blower. In a modification, the blower is mounted at the rear end of the separator and the tube exit end and the separator are mounted on threaded rods so that the tube may be inclined at any desired angle. In a further modification, a rigid tube provided with an internal vibratory bottom plate is used and a tubular heating spiral is arranged around the tube for circulation of a heating medium to supply further heat to the drying gas.

Patent GB-613080-A (GB)
Title: Improvements in the preparation of stable medicinal salts of acetylsalicylic acid
IPC: A61K47/02
Filed: 1946-05-17
Abstract: Solid dry stable preparations of calcium or magnesium acetylsalicylate are manufactured by intimately incorporating therewith a minor amount (e.g. 2-3 per cent) of calcium or magnesium chloride and a minor amount (e.g. 0.25-0.4 per cent) of calcium or magnesium carbonate.  The process may be effected, in the case of calcium acetylsalicylate, by adding, with even admixture, to a filtered concentrated aqueous solution of an alkali metal (e.g. sodium) salt of acetylsalicylic acid, a small quantity of an alkali metal (e.g. sodium) carbonate, precipitating the product with excess of calcium chloride, filtering, extracting liquid until the product retains the desired amount of calcium chloride, and drying, advantageously at 45-50 DEG  C.  Preparations of magnesium acetylsalicylate may be obtained similarly by replacing the alkali metal salt of acetylsalicylic acid by magnesium acetylsalicylate, the alkali metal carbonate by a carbonate of magnesium (preferably the basic carbonate), and the calcium chloride by magnesium chloride. Examples of both these procedures are given.

Abstract: 965,161. Educational appliances; magazine tape recorders. GENERAL ELECTRONIC LABORATORIES Inc. April 19,1962,No. 15225/62. Headings G5G and G5R. [Also in Divisions H1 and H4] An audio teaching aid system comprises a plurality of student positions together with recording and playback apparatus in a remote location relative to the student position, and a control console incorporating switching means whereby selected ones of the student positions may be coupled to the recording and playback apparatus. In the described embodiment a plurality of student positions, e.g. 50 and 52, Fig. 1, each equipped with a microphone and headphone set are connected via a teacher's control console 74, equipped with a microphone 96 and headphones 94, to a bank of double track recorders 24 in the rack 12, Fig. 2. One track on each recorder carries a lesson to be transmitted to the student positions and by operating switches 80, of which there is one switch for each student, on the control console 74 the teacher may connect any tape recorded lesson to any one, or any group, of the students. Gaps are left in the recorded lesson to allow the student to answer questions put to him and the lesson and the students' replies picked up by microphone 62, are recorded on the other track of one of the tape recorders 24 to which the student's microphone is permanently connected. By operating one of the switches 77, of which there is one for each student associated with the lesson selector switch 80 for that student, the teacher may monitor the lesson being transmitted to the student and his replies or may talk to the student via the teacher's microphone 96. In addition by operating "intercomm" switch 88 the teacher may address all the students. The tape mechanism 24, which plays a continuous loop of tape in a removable cassette may be stopped at the end of the lesson by the detection of a conducting stripe on the tape, alternatively in one position of lesson selector switch 80 the student's headphones are connected to monitor his own recorded student track so that he may analyse the lesson and his replies and, in this condition, the tape is played continuously to repeat the lesson. A further position of the lesson selector switch 80 connects the student's headphone to hear the lesson selected by switch 84, in this condition the teacher may easily change the lesson for a group of students. A complete circuit diagram for the equipment is provided, Fig. 3, not shown. Tape mechanism Figs.4 and 6. The endless loop of tape in the cassette 592 is driven, by idler wheel 576 past the erase and playback heads 582, 584, and 580 and the conductive strip sensing contacts 586. The tape cassette is inserted and removed with idler wheel 576 moved into the position shown in Fig. 6, by pressing knob 575 toward the panel. When the cassette is inserted the tape drive is engaged by pulling knob 575 when the idler wheel moves through 90 degrees from the position shown in Fig. 6, to press the tape into engagement with drive shaft 560.
