Title: Improvements in or relating to double cylinder circular knitting machines provided with a coupling
IPC: D04B15/88
Filed: 1949-03-09
Abstract: 660,159. Claw clutches; lost motion couplings. SVIT, NARODNI PODNIK. March 9, 1949 [March 18, 1948], No. 6450/49. Class 80 (ii) [Also in Group VIII] Synchronous rotation of the needle cylinder and take-down drum, for receiving the knitted product, of a circular knitting machine is maintained during continuous rotary knitting by a coupling comprising a number of freely rotatable discs each having an upstanding stud engaging in a concentric arcuate groove in an adjacent disc so that during reciprocatory knitting the studs idle in the grooves without transmitting the reciprocatory motion of the needle cylinder to the take-down drum. As described, the end of a shaft 1 receives a key 4 having a nose 5 which projects through a slot 2 in the shaft 1 to engage a boss 6 of a disc 7 having an upstanding stud 8. The stud 8 projects into a groove 9 of a disc 10 freely rotatable on the shaft 1 and which also has a stud 11 which projects into the groove 12 of a similar disc 13. The stud 14 of the disc 13 projects into the groove 15 of a gear wheel 16 meshing with a gear wheel 17 secured to the take-down drum. During continuous rotary knitting the studs engage the ends of the grooves and the motion of the needle cylinder is transmitted to the take-down drum. On commencement of reciprocatory knitting the studs are moved towards the opposite ends of the grooves, the total length of the grooves being sufficient to ensure that the stud 14 does not engage the end of the groove in the gear wheel 16, so that the reciprocatory motion of the needle cylinder is not transmitted to the take-down drum. A washer 31 may be rotatably connected to the key 4 which is normally urged into its operative position by a spring 3 enclosed in the end of the shaft 1 by a screwed in member 29. Pins 32 project from the washer 31 into holes in the member 29 and when it is desired to disconnect the drive from the shaft to the take-down drum the washer 31 is pulled down withdrawing the key, against the spring 3, from engagement with the slot 2 and at the same time withdrawing the pins 32 from the holes in the member 29. The washer is then turned to retain the key in its inoperative position.

Title: An Improvement relating to the Justification of Operands in an Arithmetic Unit.
IPC: G06F7/52
Filed: 1967-02-10
Abstract: 1,179,274. Data processing ; division HONEYWELL Inc. 10 Feb., 1967 [28 Feb., 1966], No. 6620/67. Heading G4A. A pair of multidigit operands are justified before arithmetic operations are performed thereon by alternately scanning the operands digit-by-digit and from opposite ends until indications of the highest order digit of that one of the operands which is scanned from the low order end is detected. In a character processor having an arithmetic unit operating serially by character on variable length operands, before a division operation by the over-and-over subtraction technique is started the divisor and dividend operands are scanned alternately character-by-character to establish their lengths so that unnecessary initial subtractions are avoided. As described, a divide instruction comprises a function code field, an A or divisor address field and a B or dividend address field. Each stored character comprises 9 bits, four bits storing digital information in BCD or binary form, two zone bits used in the units position of an operand for indicating its sign, two punctuation bits used as a word mark to indicate the high order end of an operand and one parity bit. The A address of the divide instruction indicates the units position of the divisor whereas the B address indicates the high order end of the dividend. In the performance of the divide instruction the operand digits are initially scanned alternately by respectively decrementing and incrementing A and B address counters until either the word mark of the A operand or. the sign bits of the B operand are detected. If the sign bits of the B operand are detected first, indicating a fractional quotient, the instruction is terminated after determining the sign of the quotient. If the word mark of the A operand is detected first a reverse scan with corresponding counter modifications may be initiated to check for insignificant zeros and then the division operation proper is started with the operands so aligned that a useful subtraction is achieved immediately. Subtraction is parallel within decimal digit. When a change of sign in the partial remainder is detected the divisor is added back and subtractions continued with the operands in shifted relationship. Also when a change of sign is detected, a temporary register tallying the number of successful subtractions is transferred to the quotient area which is provided adjacent to the high-order end of the dividend and may, if necessary, extend into the original dividend area as this contracts. Three working areas for storing reference addresses associated with the divisor, dividend and quotient, respectively, as well as two counters for sequentially accessing the characters of the divisor and dividend are provided. The operands and instructions may be stored in a magnetic core store. A control memory comprising sixteen 15-bit registers is provided for programme sequencing and other functions.

Title: Dielectric support for ferrites in waveguide devices
IPC: H01P1/175
Filed: 1956-03-02
Abstract: 810,131. Waveguide accessories. HUGHES AIRCRAFT CO. March 2, 1956 [March 2, 1955], No. 6707/56. Class 40 (8). A high-power waveguide device for rotating the plane of polarization of microwave energy comprises a ferrite element associated with a dielectric supporting element which contacts the ferrite element at points of minimum electric field strength. Arcing between the ferrite element and its support is thus prevented. The ferrite element may be in the form of a cylinder 14, Fig. 1, supported by three spaced dielectric discs 16, 18, 20 having central apertures to receive the cylinder. The sides of the central apertures are cut away at 22 and the cut away portions are arranged to lie on the line of maximum potential gradient, i.e. along the line defining the direction of polarization. Since the wave is rotated by the ferrite element the disposition of the cut-outs is varied in the manner shown. In a modification (Fig. 2, not shown), the support is in the form of a dielectric box which fits within a square-section waveguide. The end faces of the box are centrally apertured to receive the ferrite element and the apertures are cut away at the points of maximum field strength after the manner shown in Fig. 1. The box is provided with extra apertures to facilitate the circulation of a coolant. Means for producing the axial magnetic field necessary to the operation of the device are omitted from the drawings.

Abstract: 249,130. British Thomson-Houston Co., Ltd., (Assignees of Traver, O. C.). March 11, 1925, [Convention date]. Switches partly electromagnetic; t h e r m a l switches. -- The thermal element of a thermal switch is heated by the current induced in it by a varying magnetic field produced e.g. by an alternating current. According to the arrangement shown in Fig. 1, the bi-metallic strip 10 has the shape of an annulus which surrounds the core 11 of the electromagnet 15. When the magnet 15 is energized by an alternating current, induced currents circulate round the annulus, heating the strip and causing a contact 13 carried by it to engage a contact 14. This action is assisted by magnetic attraction between the bi-metallic strip 10 which is of magnetic material and an adjustable pole-piece 21, a magnetic insulator 17 serving to produce free poles above and below it. Further adjustment is obtained by moving a plug 18 and pin 19 of magnetic material, up or down. In a modification, the bi-metallic member is in the form of a hollow rectangle surrounding the core.

Filed: 1921-03-03
Abstract: 159,893. Leavitt, F. M., and Newton, E. R. March 11, 1920, [Convention date]. Water-tube boilers; feed-water, supplying. - Relates to a steamgenerator having (1) means for controlling the feed-supply, (2) means for controlling the fuel and air supplies to the burners, and (3) means such as a throttle valve for allowing steam to pass to the engine only when a predetermined pressure is reached, and relates more particularly to a generator of the kind described in Specification 145,707. The heating is controlled by regulating the supply of liquid fuel under pressure in turn to one, two, or more of a group of, say, ten burners. The fuel and feed pumps are driven at a uniform speed, the surplus fuel and water being by-passed to the tanks. The feed pump E, Fig. 1, the fuel pump t, and the air fan G of the coiled-tube flash generator shown are driven by a motor D, and the steam outlet is controlled by a throttle valve, as described in the Specification referred to. The valve mechanism controlling the supply of fuel to the burners M comprises a number of D-shaped sliding valves, which are so operated by cam surfaces on a plate rotated by a handle that one, two, or more of the fuel-supply pipes 3 are placed in turn in communication with the fuel-inlet chamber, or with an exhaust passage. A valve operated by fluid pressure closes the fuel inlet when either a safetyvalve V in the feed by-pass pipe 400, or a valve U operated by a thermostat S exposed to the steam are opened. Expansion of the tubular elements of the thermostat first closes a by-pass valve T in the by-pass pipe between the pump outlet 4 and feed tank K. Further expansion of the elements opens the valve U.

Abstract: 396,324. Supporting conductors; mechanical cut-outs for overhead conductors. MATHIEU, M. E., 22<bis>, Rue Labillardiere, Alenþon, Orne, France., March 8, 1933, Nos. 7066 and 7067. Convention dates, March 9, 1932, and Jan. 17, 1933. [Classes 36 and 38 (i).] In order to interrupt the circuit in an overhead electric conductor in case of breakage, the conductor is made in sections connected through pivoted arms and contact springs which are separated by counterweights on the breaking of the conductor. For this purpose the conductor 7 may terminate in a chain 9 passing over a pulley 10 and carrying an insulated counterweight 11. Adjacent sections of conductor are connected by. pivoted bars 5 and springs 8. The chain 9 passes through a slot in the bar 5 so that the weight 11 has a certain freedom of movement, but on its passng this limit a stop 13 strikes the bar 5 and moves it away from the next bar. An insulated chain 17 may be provided for separating the sections by hand. For polyphase instalments the bars 5 corresponding to the several phases may be mechanically connected and electrically insulated, so that the breaking of a conductor in one phase interrupts all the circuits. In a modification the pulley 11 is dispensed with, the chain 9 passing through a slot in a fixed stop against which the weight 11 abuts.
