Title: Low inertia rotor for dynamo electric machines and method of making the same
IPC: H02K3/26
Filed: 1970-07-10
Abstract: 1322065 Making dynamo-electric machines ETABS E RAGONOT 10 July 1970 [10 July 1969] 33723/70 Heading B3A [Also in Division H2] A low inertia core-less rotor for a dynamoelectric machine comprises (Fig. 8) a hollow metal cylinder 19 with insulating material in cylindrical form on it, and a winding 12 formed on or applied to the insulating material. The rotor may be formed by electro-depositing nickel (to constitute the cylinder 19) on a cylindrical iron body, coating the nickel layer with adhesive and resin, and wrapping a winding assembly around it. The whole assembly is then placed in a pressure chamber (Fig. 7, not shown ) where an annular bladder (23) is inflated to compress it radially whilst resin is cured. Subsequently the iron cylinder within the nickel coating 19 is machined away. In a modification the nickel coating is deposited on a cylinder of low melting-point metal which can be removed by heating. The winding assembly may be surrounded by an insulating coating (31, Fig. 10, not shown) and another nickel layer (32). The winding assembly comprises (Fig. 3), a sheet of insulating material rolled into the form  of a cylinder, and a winding constituted by conductive strips which extend along the outer surface of the insulating sheet to one end where they are folded around the sheet to return along its inner surface, thus forming a loop. It may be formed by printing the conductor array, Fig. 2, on a flat sheet 1 of polyester material, cutting the ends of the sheet to conform to the shapes of the first and last conductors, folding the sheet along the axis X-X, rolling the sheet into a cylinder, and then adhering the overlapping ends 2 (see Fig. 3) together. Alternatively (Fig. 5, not shown), the conductor array is stamped from a flat metal sheet, all the conductors being temporarily united by bridges (K, L, M) which is then folded and rolled; an insulating sheet is then inserted to insulate the two conductor layers and the assembly adhered together before  the bridges are cut to electrically separate individual winding loops. In either case instead of a single fold, a number of folds may be made in a zig-zag fashion to form several superposed sets of conductor loops. End portions E of the conductors are thickened by electrolysis to act as a commutator, and each is connected to the end portion S lying beneath it by a tin or copper plug passing through holes 4, thus connecting all the winding loops in series

Title: Electrically controlled means for starting-up internal combustion engines
IPC: F02N99/00
Filed: 1922-12-11
Abstract: 211,279. Fisk, E. T. Dec. 11, 1922. Starting; turning-gear.-A priming charge of petrol or the like is delivered by gravity from a container 7, Fig. 1, to a priming chamber 5 by a valve 11 actuated by an electromagnet 20. The chamber 5 is connected to the induction pipe or the cylinder heads. The valve is normally closed' by a spring 17, and is opened by the action of the electromagnet on an armature 13 on the valve stem. In a modification, Fig. 3, the interval between the opening and closing of the valve 11 is controlled by a dashpot 50. When the switch arm 36 is moved on to a contact 34, current is supplied to a solenoid 53, the core 52 of which carries the dashpot piston 51. An extension 54 on the core 52 carries a contact 55 which completes the circuit 37, 37<1> of the electromagnet 20. The switch 36 is then moved off the contact 34 until the circuit 37, 37<1> is opened, after which it is moved on to a contact 35 closing the circuit of a dynamo 33, which is used as a motor for starting the engine. The switch contacts may be so arranged that, on stopping the engine, a further petrol charge is admitted to the engine, leaving a rich mixture in the engine and tending to reduce carbonization. In a further form, the closing of the valve 11 is affected by a float in the chamber 5, which opens the circuit of the electromagnet controlling the valve when the desired quantity of petrol has been admitted to the chamber.

Filed: 1968-07-17
Abstract: 1,177,609. Dividers and addition; data storage. INTERNATIONAL BUSINESS MACHINES CORP. 17 July, 1968 [9 Aug., 1967], No. 34107/68. Addition to 1,177,608. Headings G4A and G4C. Apparatus for dividing the sum of multiorder numbers by a predetermined divisor, generates the sum, generates an intermediate remainder for each order, and combines each order of the sum with the intermediate remainder for the next higher order to produce an intermediate dividend which is divided by the predetermined divisor to produce the quotient, the intermediate remainder for the lowest order being the final remainder. A binary-coded octal index quantity M is added to or subtracted from a binary-coded octal memory address N and the result divided by 3 as in Figs. 10A-10C. Each octal digit of M is applied in true or 7s-complement form (according as addition or subtraction is required) by gates G (Fig. 10A) to a carry-lookahead adder CLA (not shown) and via a respective unit C to a mod 3 adder respective to the octal order. Each octal digit of N is applied to the CLA adder and via a respective unit C to the corresponding mod 3 adder. Each unit C passes its input mod 3. The mod 3 adders feed an arrangement of mod 3 adders and mod 3 subtractors (Fig. 10B) to produce a quantity R in each octal order. The quantities R are combined with respective carries C from the CLA adder and a feedback signal (see below) in respective units P s , P A  to produce an intermediate remainder in each octal order. Each unit P A  produces (R+C+ feedback) mod 3 and each unit P s  produces (R + C - feedback) mod 3. The other intermediate remainders each constitute the high-order digit of a two-octal-digit octal number which is the input to a respective Q f -Q p  box, the low-order digit being a respective sum octal digit from the CLA adder. A further Q f -Q p  box 10 receives the highestorder sum digit and a high-order carry C, from the CLA adder. Each Q f -Q p  box divides its input by 3 and passes the integral portion of the result out as a respective digit of the final quotient. The high-order carry from the CLA adder is not added-in in subtraction and optionally may be similarly discarded in addition. In either case the C input to Q f -Q p  box 10 is set to 0 and in the latter case if the highorder-carry is in fact 1 the feedback line shown is energized to add 2 to each P s  unit and subtract 2 from each P A  unit (2 being 8 mod 3). The carry input into the P A  unit 22 is a " hot one " equal to 1 only in the case of subtraction. This " hot one " is also applied to the CLA adder in subtraction. The above system may be modified for other radices than 8 and other divisors than 3 as in the parent Specification, the abridgment of which explains the rationale of the mod 3 adders and subtractors. Data storage.-The final quotient from the indexed address may be used for addressing a memory to access a memory word comprising a plurality of data words, the final remainder selecting one of the data words.
