Patent GB-245474-A (GB)
Title: Improvements in methods of preparing flaked cereal food products
IPC: A23L1/168
Filed: 1926-01-04
Abstract: 245,474. Heinz Co., H. J., (Assignees of Harding, E. R.). Jan. 3, 1925, [Convention date]. Cereal preparations in flaked form are prepared by cooking with the grain substantially pure cellulose, the mass being dried incompletely and then separated mechanically into the original kernels which are dried and flaked. The cellulose employed is preferably derived in finely divided condition by chemical treatment of vegetable substances such as corn cobs; cotton, or wood pulp. Cellulose obtained in other ways may, however, be used, provided it is substantially pure and free from starch or other substances which become gelatinous on cooking. In the application of the invention to the preparation of flaked rice, for example, cellulose to about 10 per cent by weight of the rice to be prepared is brought into suspension in water, the rice is added and the whole mixed and cooked. The cooked cereal is then prepared by flaking by incomplete drying followed by mechanical separation into fragments as in an horizontal rotating cylindrical container fitted with internal longitudinal ribs or ledges. The Specification as open to inspection under Sect. 91 (3) (a) refers to United States of America Specification 1,495,789 and also to the mere cooking of cereals wherein, in order to ensure the preservation of the identity of the individual kernels, cellulose in finely divided condition is added. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to electric circuit breakers
IPC: H01H73/56
Filed: 1936-01-03
Abstract: 452,752. Automatic circuit-breakers. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Jan. 3, 1936, No. 308. Convention date, Jan. 3, 1935. [Class 38 (v)] The movable contacts 3 of a circuit-breaker are moved into engagement with the fixed contacts 2 against the action of a spring 23 by means of a lever 16 which is pivotally mounted near one end and movable in an endwise direction by force applied through its fulcrum, the resulting movement of the other end of the lever being caused to urge the movable contacts into the engaged position by a non-articulated engagement of said end with a member connected to the movable contacts, means being provided for maintaining the lever in the engaged position and for moving it about its fulcrum when the contacts are to be disengaged. In the two-pole switch shown, a pair of contacts 2, 3 are provided for each pole, and in the closed position, the current of each pole flows through a pair of bimetallic strips 4, 5 and through a coil 6. The lever 16 is pivoted at 15 on one arm of a bell-crank lever 13 pivoted at 14, the other arm of the lever having a shoulder 12 which is engaged by a fork 11 on a pushbutton 10. When the button is pressed to the left to close the circuits, a pivoted catch 25 engages the shoulder 12 to maintain the lever 16 in the circuit-closing position. The other end 17 of the lever 16 engages a roller 18 carried by a double fork 19, 19<1>, which also carries an element 20 carrying the movable contacts 3. The fork is carried by a guide rod 22 sliding in a member 24 against the action of the spring 23. Automatic release is effected by a member 37 pivoted at 38 and having an arm 39 adapted to engage an arm 40 carried by the lever 16. On heavy overloads, the core 36 of the winding 6 rises and strikes the member 37, the arm 39 of which then engages the arm 40 and pushes the lever 16 to the right to release the roller 18. At the same time a link 29 connected to a pin 30 on the lever 16 moves the catch 25 out of engagement with the shoulder 12. On prolonged overloads of less intensity, the bimetallic strips 4, 5 move in the direction of the arrow f, Fig. 5, and release a member 42 pivoted at 44. The member 42 then moves under the action of a spring 46, and a member 45 carried by the member 42 strikes the release member 37 to open the circuit. When the circuit opens, a head 47 on the contact carrier 20 resets the member 42. The member 42 may incorporate a second bimetallic strip to compensate for variations in ambient temperature. The setting of the bimetallic blades 4, 5 may be regulated by a screw. A separate push-button 31 is provided for use when manual opening of the circuit is desired.

Abstract: 1382918 Digital calculators CASIO COMPUTER CO Ltd 7 Jan 1972 [11 Jan 1971] 813/72 Heading G4A A data processor system for performing arithmetic operations on items relating to bills of sale, the items being arranged in tabular form, includes a program which causes the processor to perform the required operations automatically as the operator feeds in the relevant data. In the embodiment disclosed, the operator keys in the number of like units sold (column 1), the selling price/unit (column 2), and the stock price/unit (column 4). These values are recorded in tabular form by a printer. The processor computes the total selling price and records it in column 3 when the tab key is pressed after the selling price/unit has been keyed in to column 2, and computes the total stock price (column 5) and the profit (column 6) after the stock price/ unit has been keyed into column 4. Similar operations take place when the operator keys in to the next row of the tabular format data relating to other units. Either automatically or on command of the operator the processor can sum the values in columns 1, 3, 5 and 6 respectively.  When the print head is advanced to column 1 a column counter is incremented from 0 to 1. The counter is incremented each time the head moves from one column to the next. Following each increment the processor determines whether or not a number indicative to the program step currently stored in a register is equal to the number on the column counter. If it is equal, the arithmetic operation specified by this step of the program is performed, the result being stored and also printed in the appropriate column. The contents of the register are then replaced by the next program step in readiness for the next arithmetic operation called for. At the end of each row of the format and counter is set to 0 and the first program step is read in to the register.
