Title: Improvements in and relating to hose and the like and circular knitting machines therefor
IPC: D04B9/46
Filed: 1941-03-15
Abstract: 547,900. Knitting. TOONE, H. B. S., and TOONE, H. S., (trading as TOONE & CO., B.), and COLE, B. T. March 15, 1941, No. 3574. [Class 74 (ii)] In knitting stockings and like articles having heel and toe pouches upon a circular machine, the pouches are formed by rotary knitting. The needles for knitting the pouch are divided into end groups B, B<SP>1</SP> which are raised to loop-holding position with the instep needles A, and needles C which always remain active. Jacks 22 are provided beneath all the needles, and pickers 39, 40 and 42, 43 are provided for raising and lowering the leading and trailing jacks so that' the corresponding needles are raised to loopholding position and re-lowered to operative position. By providing jacks having alternately three-quarter and short butts 22a, the jacks can be divided by a pattern-controlled bolt cam 37 into two series, one alternating with the other and being raised by the cam 37 to a picking level 38 so that the first two land trailing two jacks can be picked by the raising pickers 39, 40 and the corresponding needles hold their loops. The cam 37 is then pushed right in to engage the short butts 22a and the first and trailing two short butted jacks are raised by the pickers. A suture 12, 14 in which there is an overlap between the held and knitted loops is thus formed, and the held loops may be accumulated to form knops. The picker 40 for raising the leading two jacks of a series has a ledge 40a of sufficient width to receive the butts of two such spaced jacks, and the picker 39 is provided with a short ledge 39a, a projection 39b by which it is swung by the butt; and a longer ledge 39e which prevents the picker operating until the last two butts arrive over the narrow ledge 39a and recess 39c. The pickers 42, 43 are similar to the pickers 39, 40, but are inverted. Cams 44, 45 are controlled by pattern mechanism to divide the jacks into two series, so that during widening of the pouch the held and knitted loops can be similarly made to overlap. Yarn feeding and cutting mechanism as described in Specifications 532,520 and 532,586 may be provided, together with means for locating the cut end of yarn within the needle circle so that the re-introduced yarn can be supplied to the correct needle. The pouch may, as described, be made by first narrowing and then widening, or alternatively, all but the needles C may be moved to loop-holding position, and then first widening and subsequently narrowing may be effected to form a suture with lines disposed in the form of a diamond. According to the Provisional Specification the picker mechanism may be as described in Specification 469,507.

Abstract: 868,498. Roller mills. MILLS, E. C., and WESTERN BOARD MILLS Ltd. Jan. 19, 1959 [Feb. 4, 1958], No. 3589/58. Class 59 [Also in Group XVI] A roller mill comprises a frame, a main bed member mounted on the frame, spaced discs mounted for rotation on the frame, mounting blocks carried on the discs, a plurality of rollers extending between the mounting blocks and parallel to the bed member, means for rotating the discs, means for locking the discs to the frame to dispose a selected roller adjacent to the bed member, and means for rotating at least one of the rollers. The bed member in the form of a roller 1 is carried by the main frame 3 and can be raised and lowered therein by means of hydraulic rams 17. Rollers 5, 5A which may be of the same or different diameters are rotatably mounted in bearing blocks 7 formed integrally with or attached to gear wheels 8. Circular discs 9 are also mounted on the gear wheels 8 and these are supported by freely revoluble rollers 10 carried by the frame 3. Four arms 13 are formed integrally with each block 7 and each arm is formed with a hole 14 or 14A. When each pair of holes 14A registers with a pair of holes formed in lugs 15 on the frame 3 the roller 5A is at the working station, as shown, and pins are inserted in the registered holes to lock the roller carrying structure in that position. When the pins are removed the roller carrying structure may be rotated, by means of hand-operated turning gear 12 which acts upon the gear wheels 8, until the pairs of holes 14 come into register with the lugs 15. The pins are again inserted in the registering holes and the roller 5 is thus locked at the working station. The shaft ends 6, 6A of the rollers 5, 5A carry coupling discs 18, 18A either of which when the corresponding roller is in the working position can co-operate with or constitute part of a coupling mechanism, e.g. an Oldham coupling 19, which is driven by an electric motor 22. A gear wheel 23, 23A carried at the other end of each roller meshes with a gear 24 carried by the roller 1 to transmit the drive to the latter roller. In modifications three or four rollers may be' mounted on the gear wheels 8.

Title: Improvements in or relating to free-piston engines
IPC: F02B71/04
Filed: 1963-01-29
Abstract: 1,029,884. Free-piston engines; starting. H. KOSOFF. Jan. 29, 1963 [Jan. 29, 1962], No. 3727/63. Headings F1B and F1K. A free piston engine comprises a unitary part 31 surrounding a combustion region 30, a plurality of members 17a, 19a each engaging the unitary part and each having a portion including a bore in communication with the combustion region, an engine piston 21b, 23b movable in each bore and means 35, 37 for maintaining each of the members in engagement with the unitary part. As shown the engine includes two rebounce chambers 41 and 43 and two pump chambers 45 and 47. A small flow of high pressure gas enters the rebounce chambers via small orifices 97, 99 to replace gas escaping through the vents 10, 14. In a modification there could be a fuel injector for applying fuel directly to the combustion chamber if the fuel device 71 is not used. In this modification the output of the pump chambers could be fed to the intake manifold for scavenging the combustion chamber. The means for maintaining the members in engagement with the unitary part may be modified. The low pressure fluid admitted by the valve 57 may be pneumatic or hydraulic. Each manifold defines a space around the inner cylinder and comprises a substantially tangential opening to the space, the cross-sectional area of the space decreasing with distance through the space from the opening. To start the engine a powder charge such as a small rim fired bullet 91 (Fig. 4, not shown), the head of which has been removed and the exposed end of which has been sealed with a combustible evaporisable substance such as "Sterno", is inserted in the hole 87. After the pistons have been moved together and the pressure in the rebounce chamber reaches a proper value the pin 81 is given a sharp knock causing the cartridge to explode and the high pressure gases to force the pistons apart.

Title: Improvements in Annealing and in Apparatus used therein.
IPC: C21D11/00
Filed: 1917-03-19
Abstract: 114,183. Hilger, Ltd., A., and Twyman, F. March 19, 1917. Pyrometers.-In annealing glass, porcelain, or some metals, the progress or completion of the process is indicated by means of a rod of the substance to be annealed, the rod being maintained under stress. The rod R, of the same substance as the articles to be annealed, is held at one end in a pillar P by a screw S<1>, and has a weight W fixed to the other end by a screw S<2>. As the temperature in the annealing-lever rises, the weight W descends and may raise a flag F, which, when the process is completed, overlaps the upright U. A formula is given in the Specification for calculating the length and section of the rod, which, to secure any desired degree of annealing, will give any desired deflection of the end of the weight.

Title: Improvements in and relating to systems of electric distribution
IPC: H02P9/18
Filed: 1927-02-14
Abstract: 266,337. British Thomson-Houston Co., Ltd., (Assignees of Seeley, H. T.). Feb. 17, 1926, [Convention date]. Running generators in parallel; systems depending on two or more machines; regulation, automatic.-The voltage of a direct-current (substation) generator 4 running in parallel with others on a distribution network 1 is automatically regulated by a relay 19 controlling a voltage raising relay 13 and a voltage lowering relay 16 associated with a reversible motor 10 operating its field rheostat, and a reverse current relay 23 co-operates with the relay 19 to prevent operation of the voltage lowering relay 16 when the normal direction of energy flow is reversed. The voltage raising relay 13 is simultaneously operated to check the reversal. An overload relay 27 normally operating at an upper load limit to prevent the raising of voltage and to operate the voltage lowering relay 16 is rendered ineffective upon energy reversal. A reverse current opens a contact 25 in the circuit of a relay 31 which thereupon opens the circuit of the voltage lowering relay 16 and closes a circuit for the voltage raising relay 13, independent of the overload relay contacts, but under the control of the voltage relay 19 so that the voltage can only be raised so long as the circuit volts are low, reversal of energy flow in other machines on the system being thereby avoided. The relay 19 may be supplied from any point on the network.

Filed: 1918-03-09
Abstract: 130,670. Greener, H. March 9, 1918. Addition to 128,617. Gun cartriges; projectiles.-Relates to multiple-bullet cartridges of the kind described in the parent Specification, and consists in the following separate modifications : (1) forming in the cartridge case the passages for transmitting the gas pressure to the several bullets, instead of, or in addition to, forming them in the bullets themselves, (2) separably connecting the leading bullet to the adjacent bullet, the latter being provided with a gas passage. In the cartridge shown in Figs. 2 and 5, comprising three solid bullets a, b, c, longitudinal crimpings or grooves d<2> are formed in the case, producing gas passages e, which allow the propellent gases to pass to the rear of the middle bullet b. The gas is transmitted to the base of the leading bullet a through grooves b<1> in the bullet b, although the grooves in the cartridge case may, if desired, extend to the bullet a. In modifications, the cartridge case may be corrugated to form contiguous straight or spiral gaspassages, or the grooves may be made by cutting: or the cartridge case may be formed with a series of internal studs or " pimples." Fig. 11 shows a cartridge case formed with circumferential grooves which allow the case to expand under the pressure of the powder gases. In the arrangement shown in Fig. 13, the leading bullet a is wholly outside the cartridge case, and is rigidly, but separably, connected to the bullet b by crimping its base into a groove b<4>. The bullet b has an axial gas passage b<5>, and the cartridge case may have longitudinal crimpings, as shown. Alternatively, the bullets a, b may be connected by disruptible ferrules or the like, or, as shown in Fig. 15, the multiple-bullet may be in one piece, the several portions being connected by narrow collars, which burst under the pressure of the powder gases entering a central passage h.

Filed: 1929-02-07
Abstract: 305,632. Telefunken Ges. fiir Drahtlose Telegraphie. Feb. 8, 1928, [Convention date]. Directive signalling.-In order to determine the 180‹ ambiguity in direction, an auxiliary loop a is mounted at right-angles to the main directional frame b, and is coupled to an open aerial (preferably that used to compensate' for re-radiation effects) through a reversing switch so as to take advantage of the cardioid curve m. The main frame b is first set for zero reception during which time the auxiliary windings a are out of circuit. When the correct setting has been found, the frame a is switched out of action, and the windings b having the characteristic curve r, r are coupled to a non- directional aerial (represented by the curve l) first in one sense and then in the reverse sense, to produce the effect of the curve m in the receiver.

Title: Wireless reception of television transmissions, which are synchronised by signals differentiated by amplitude
IPC: H04N5/08
Filed: 1935-02-11
Abstract: 451,042. Television. RADIOAKT.- GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. Feb. 11, 1935, No. 4281. Convention date, Feb. 12, 1934. [Class 40 (iii)] Synchronizing signals of greater amplitude than the television signals are selectively amplified in an amplifying-valve 17 with a curved characteristic. The valve is connected immediately in front of the amplitude filter 13 selecting the synchronizing signals and after the detector of the image signals. The amplifier 17 and the filter may be combined in a single envelope. In the case of black synchronizing signals the amplifier uses a grid-current effect with the grid capacity 20 and leakage condenser 19 so designed as not to reduce the response to high frequencies. In the case of white synchronizing signals, the valves has a strong negative grid-bias in order to amplify positive signals better than negative ones. The exaggeration of the synchronizing signals may occur in the last detector or amplifier of the intermediate amplifier 11. To prevent opposite distortion in previous gain-controlled amplifiers, the regulating voltage is applied to screening- grids, or other grids beyond the controlling- grid, which operates at constant bias.
