Title: An improved process for coating pure and alloyed light metals with a firmly adhering protection against corrosion
IPC: C23F15/00
Filed: 1936-03-06
Abstract: In the process of producing a firmly adherent, corrosion-preventing, protective coating upon pure or alloyed light metals, by the known "fat-bronzing" method, the burning-in of the thinly-applied vegetable or animal fat or oil is carried out immediately after its application, and at a temperature of about 270--380 DEG  C., in a reaction time amounting to at most 10 minutes.  By this means a uniform coating, free from streaks or spots, is obtained.  In the case of thin foils, e.g. of aluminium, they are coated with the fat or oil and then immediately placed in a space, heated to 270--380 DEG C., for a few minutes.  When thicker metal is used, it should be heated to 270--380 DEG  C., before the application of the fat or oil, and the burning-in temperature may be maintained by introducing the work-piece into a muffle, or by means of hot air.  If the metal is sufficiently thick, the burning-in temperature is maintained without further external heat supply.  It is desirable to cool the work-piece rapidly at the conclusion of the burning-in process.  The fat or oil used may be mixed with a volatile diluent, and may be previously polymerized.

Title: Data Processing Apparatus
Inventor: TSUI FRANK
IPC: G06F7/491
Filed: 1968-02-14
Abstract: 1,166,593. Subtraction for division. INTERNATIONAL BUSINESS MACHINES CORP. 14 Feb., 1968 [2 March, 1967], No. 7201/68. Heading G4A. Data processing apparatus for the iterative subtraction of a stored divisor from a stored dividend comprises two dividend stores, arithmetic means for performing subtraction operations, reading means for reading data from the dividend stores alternately in succeeding subtraction iterations and for writing the result of each subtraction into the store other than that from which data was read for that iteration, and means for inhibiting the reading means so that when the results of succeeding subtractions change from positive to negative the reading means next reads from the dividend store which was read for the last iteration. For binary-coded-decimal division by iterated subtraction, a store 3, addressed by register 4, initially holds the dividend twice and the divisor once. The register 4 can be set via lines 17 with the divisor address or with the common part of the two dividend addresses, the rest of the latter (a single bit) being supplied by flipflop 20. In each iteration, one of the dividend locations is read out through gates 6, parallel adder 1 to register 2, the address register receiving the state of flip-flop 20 in true form. Then the divisor location is read out via complementer 7 to adder 1 at the same time as register 2 is gated to adder 1 by gates 9, the remainder being passed via register 2 to the other dividend location in store 3, the address register 4 having received the state of flip-flop 20 in inverse form for this. If the remainder was positive, AND gate 44 reverses flip-flop 20 and increments quotient counter 5, the next iteration proceeding as before except that due to the reversal of flip-flop 20 the other dividend location is read out (i.e. the location which received the remainder from the previous iteration). If the remainder was negative, absence of a high order carry from adder 1 sets flip-flop 45 preventing reversal of flip-flop 20 and incrementing of quotient counter 5 but instead gating the quotient count to a quotient register 12, passing the divisor from store 3, via a shifter 8 (which shifts it by one decimal digit), adder 1 and register 2 back to store 3, resetting the quotient counter 5 and flip-flop 45, and shifting quotient register 12 in preparation for reception of the next decimal digit from quotient counter 5. The dividend and divisor could be stored in three separate registers rather than a store 3. Processing may be serial by byte rather than parallel as above. Binary operands may be used. A multiple of the divisor could be subtracted instead of the divisor.

Classes 7(ii) and 7(vi) In a four-stroke gas engine having a compression pressure of about 600 lb. per square inch at full load, the temperature of the exhaust gases is kept down to about 1000‹F., to allow the utilization of an exhaust-driven supercharger 23 supplying air as to a conduit 10, by valve mechanism 5, 13 operating to produce in the cylinder a gas-air mixture too weak to ignite spontaneously but which is fired by a spark igniter 21 preferably using an E.M.F. of the order of 30,000 to 50,000 volts. A main admission valve 5 opens towards the end of the exhaust stroke, before closure of the exhaust valve 20, to admit scavenging air from the conduit 10. Following exhaust valve closure and during the early part of the admission stroke, an auxiliary admission valve 13 is also opened to mix permanent gas under pressure from a conduit 11 with charging air from the conduit 10 in a chamber 9. The valve 13 is operated by a collar 16 on the stem of the valve 5 and has a sealing head 14, but does not operatively admit gas to the chamber 9 until passages 17 in the valve communicate therewith. The valve 13 closes before the valve 5. The permanent gas used may be a natural gas or a primary product or byproduct manufactured gas. Sewer or refinery gases may be employed. Butane or propane. which may be stored in the liquid state but are supplied in the gaseous form, may be used. The proportion of gas to air in the mixture employed is preferably one to twenty, but may be as high as one to fourteen. The engine may be regulated by a governor-controlled valve in the conduit 11.
