Abstract: 191,871. Wildt & Co., Ltd., and Wildt, E. Oct. 31, 1921. Circular machines.-In machines of the kind used for making neck-ties with patterns of tuck stitches and equipped with notched pattern wheels such as are described in Specification 11888/08, controlled by an intermittently rotated drum 21, additional control drums 26, 45 are provided the drive of which is controlled by prearranged pattern mechanism. The additional drums permit the pattern to be repeated or not as required. The clearing-cams 1, 2 for acting on double-butted needles are mounted on rockers 3, 4 pivoted at 5, 6. When the invention is applied to machines fitted with single-butted needles only one tucking wheel is employed. The rockers are actuated by sliding bolts 7 - - - 10 associated in pairs and moved by means of rock levers 11, 12, links 13, 14, and levers 15, 16, bearing on the removable dogs of a pattern drum 21 driven by a clawker 22. The levers 15, 16 can also be raised to cause the bolts 7, 9 to elevate the cams 1, 2 to clearing position by means of a pin 29 projecting from an arm 28 which is lifted by dogs 27 on an additional pattern drum 26 driven by a pawl 30. The drum 21 is sleeved on the drum 26 and is controlled by means of a lifter 32, pivoted at 33. During rotation of the drum 21 studs thereon raise the lifter 32 which raises a pin 36 projecting from the clawker 22 until the clawker no longer drives the drum. A projection on the lifter is also engaged and held in raised position by a shoulder on a spring-acted lever 39. The lifter 32 and clawker 22 are released when a stud 41 on a pattern chain 42 bears against the end 43 of the lever 39. The bolts 7 - - 10 are further controlled from another drum 45 carrying two series of dogs which move rock levers 47, 48 fitted with laterally projecting pins 49, 50 adapted to depress the ends of the levers 15, 16. The drum 45 is operated by a clawker 51 on an oscillating lever 24a, a member 52 being provided which when actuated by pins 54 on the side of the drum lifts the clawker 51 to stop the drive. When raised the member 52 is held up by a lever 56 which can be tripped by a stud on the pattern chain. The mechanism described above is used in conjunction with yarn-changing means.

IPC: D21F1/32
Filed: 1925-11-16
Abstract: 263,594. Vickery, F. W., and Johnson, L. S. Nov. 16, 1925. Felts.-In the cleaning of paper machine felts, particularly those of cylinder machines where the stock is picked up in a very wet condition, the washing of the felt to clear it of short fibres, colouring, and loading matter is effected by a reciprocating nozzle 2, Fig. 2, inclined to the felt as shown and set so that the vena contractor of the jet is at the face of the felt. the latter being maintained under tension as by a plate 3 pressed upwards by springs or by a counterpoised lever, the jet being directed between the plate and the felt 1. A corrugated roller 9 may be used to give intermittent support to the felt and a similar roller 11 may be used to make the action of the jet intermittent. The jets may be arranged in rows and so distanced that each jet acts to limit the lateral spread of adjacent jets. Air jets 6 may be used to press the felt 1 against the plate 3 and similar jets 7 directed slant-wise to the edges of the plate may assist in confining the water laterally. The cleaning action may be supplemented by a steam jet terminating in a narrow slit in the middle of the plate 3. The jet of water 25 may be confined within a suction box 20, Fig. 5, provided with glass rods 21 to make a tight joint with a minimum of friction, other glass rods being provided as shown to limit the extent to which the felt is drawn downwards. Rows of jets 2, 25 may be arranged in pipes 16, 23 which are reciprocated lengthwise a distance slightly greater than the space between adjacent nozzles. Specification 188,023 is referred to.

Title: Apparatus for and method of detecting an article and maintaining the same in a desired position relative to a member
IPC: B65G47/61
Filed: 1973-06-19
Abstract: 1434133 Automatic control of speed TSUBAKIMOTO CHAIN CO 19 June 1973 [20 June 1972 14 March 1973] 29116/73 Heading G3R The relative speed between a moving article 1 and a movable member 2 is controlled by a rotatable member 4, on the movable member 2, that is biased against the article 1 and provides an electrical control signal dependent upon the relative position of the member 2 and the article. In the embodiment see also Figs. 2 to 10 (not shown) member 2 is a carrier and article 1 is part of a moving conveyer. Arm 11 on the carrier 2 drives a potentiometer, whose output is amplified to control a hydraulic cylinder or electric motor driving the carrier. The carrier speed is thus varied to maintain the relative speed, and thus position, between the carrier and the conveyer at a desired value or between pre-set limits. The arm 11 is spring-biased against the conveyer 1, or against a stop when not in use. Provided the arm is within a given range of positions, as detected using reed switches and an electromagnet or using a light source and phototransistors, the apparatus of the carrier 2 such as transferring, processing or inspection equipment may be used.

Patent GB-427890-A (GB)
Title: Improvements in the treatment of ammonia liquor for the separation of impurities or other constituents therefrom
IPC: C01C1/10
Filed: 1933-10-20
Abstract: <PICT:0427890/III/1> In the treatment of ammonia liquor with steam which removes ammonia with some other constituent, such as phenol, the liquor is divided into portions which are separately treated and the steam is passed successively through the several portions, but is subjected between each pair of passages to treatment which will remove from it the phenol or other absorbed constituent.  In the apparatus shown, ammoniacal liquor passes from a still 10, in which H2S, CO2 and free ammonia have been removed from it by steam, to a device 17 which distributes it in equal portions to dephenolizing chambers 13, 14, 15.  The treated liquid from these chambers is collected in a main 21 and delivered to a vessel 11 where it is treated with lime to set free the fixed ammonia.  The liquid passes on to a still 12 where the ammonia is removed by means of steam.  The steam used in the several parts of the apparatus is supplied initially to the still 12, and passes thence through a pipe 25 to the bottom of the chamber 15.  In the chamber 15 the steam passes through the liquid under treatment in counter-current, and carries the phenol with it to a chamber 26 to which a solution of caustic soda is supplied intermittently through a pipe 27 from a meter 30.  The phenol is separated as sodium phenolate and the steam passes on successively through the chambers 14, 13, phenol being separated again by means of caustic solution after it has left each of these chambers.  The steam finally passes through a pipe 34 to the still 10.  The solution of sodium phenolate is collected in a tank 32.  The chambers 13, 14, 15 may be packed with wooden hurdles, or spiral tiles and the chambers above containing caustic solution may be packed with steel turnings.  Modified apparatus is described in which the chambers 13, 14, 15 and the upper chambers containing caustic solution are arranged as compartments within a single shell and internal passages are provided for conveying the steam from one chamber to another.  All the compartments are lagged to prevent heat losses.  The Specification as open to inspection under Sect. 91 describes also the use of the process and apparatus for the treatment of other liquids than ammonia liquor with fluids other than steam. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to sockets for electrical devices
IPC: H01R33/76
Filed: 1945-11-03
Abstract: 603,893. Holders for discharge tubes. SPERRY GYROSCOPE CO., Inc. Nov. 3, 1945, No. 29231. Convention date, Nov. 4, 1944. [Class 38 (i)] A socket for a discharge or like device 1, having a cap 2 carrying one, or more terminals 4, comprises a casing 10 within which is located a connector 11 having tabs 12 which engage slots 19 in casing. A guide ring 16 is rotatably mounted in a mounting ring 9, secured to the top of the casing, the ring 16 having holes 24 therein co-operating with holes 25 in the ring 9 to receive the ends of mounting studs 7 carried on a flange 6 on the discharge device which is then locked in the socket by rotating it so that grooves in the ends of the studs 7 enter slots in spring members 26 cut from the ring 9. Lugs 17 are provided for mounting the casing in a chassis. The initial insertion of the terminals into the connector causes the tabs 12 to leave notches 28 in the slots 19, where they are maintained in the disconnected position, by a helical spring 29, and engage further notches 20. The discharge device is then rotated slightly to locate the studs 7 in the holes 24, whereupon it is rotated further to the locked position, the tabs 12 then being located in the wider lower portion of the slots 19 so that the connector 11 is floating with respect to the casing. The spring 29 may be omitted. Alternatively, ballshaped heads may be provided on the studs 7 engaging suitable sockets in the ring 9.

Title: Motor control system with linear acceleration circuit
IPC: H02P7/292
Filed: 1970-06-16
Abstract: 1285286 Automatic speed control  BORG-WARNER CORP 16 June 1970 [30 June  1969] 29255/70 Heading G3R  A reversible series motor 20 is shunted by a freewheeling diode 50 is energized through rectifiers 25-27 having firing circuits 28-30 which are controlled by an amplifier 32 receiving a signal related to the terminal voltage of the motor over line 60. The amplifier 32 also receives a speed reference signal over line 61 from a linear acceleration stage 62, which translates a step function change of the setting of potentiometer 63 into a gradual transition of the signal applied over line 61. When there is no variation in the signal provided by the potentiometer 63, operational amplifier 80 maintains transistor 84 conductive whereby the charging circuit of the capacitor 81 is disabled. If a stepup signal is applied from the potentiometer 63 to the amplifier 80, transistor 84 is turned-off and capacitor 81 begins to charge. This produces a ramp waveform signal which is passed through transistor 97 and over conductor 61 to the amplifier 32. The capacitor 81 is rapidly discharged when the potentiometer 63 is adjusted to signal a speed decrease. A substantially linear slope of the signal passed over conductor 61 is provided by arranging that the voltage applied to terminal 98 is much larger than the voltage developed across the capacitor 81 whereby only the initial portion of the capacitor-charging waveform is applied to the amplifier 32. Negative feedback through resistor 90 determines the point at which the ramp signal on line 61 is terminated. The transistor 97 is biased to prevent appreciable dead time in the ramp function output when setting the speed up from zero.
Patent GB-414030-A (GB)
Title: Improvements in carburettor for internal combustion engines
IPC: F02M17/00
Filed: 1932-10-21
Abstract: 414,030. Spray carburetters. LANG, O., 13, Opernring, and GROBER, F., 6A, Bischof Faber Platz, both in Vienna. Oct. 21, 1932, No. 29462. Void [Abridged as open to inspection under Sect. 91 of the Acts, March 12, 1934]. [Class 7 (iii).] In a carburetter, an intermediate member, disposed between the fuel supply valve and the actuating member therefor, is adapted when the engine is running idly to be freely and axially movable to a limited extent and to be operated solely by air suction to control the valve, but when the carburetter controls are being operated to run the engine under load it is rigidly connected to the actuating member and is positively controlled. In the former case, air, sucked through inlets 10 in a fixed casing 1, rotates a member 19 having vanes 23 surmounted by a ring 31 which increases the face area exposed to the air. The member 19 lifts and opens a needle valve 20 permitting fuel to flow into a recess in the dished top of the member 19 from which it is flung into the air stream by centrifugal force. The needle valve 20 is mounted in a streamlined member 21 having its lower face shaped to fit the dished top of the member 19 so that fuel is not wasted when the carburetter is in an inclined position. The member 19 forms part of a ball race of which the inner part 18a is mounted on a non-rotatable shaft 15 adapted to slide axially in a hollow shaft 12. In the upper wall of an annular recess formed between two collars 26, 15a, Fig. 4, on the shaft 15 are recesses 26a which in the idling position are engaged by projections 25 on a cap 24 secured at its lower edge to a disc 12a on the hollow shaft 12. The disc 12a is slidable in, but non- rotatable with respect to, an annular slide 3 pressed upwards by a spring 4 to close air inlets 7 in the casing 1. The ball race 18, 19 and shaft 15 have thus some freedom for axial movement relative to the cap 24 and disc 12a and the member 19 can operate the valve 20 during idling. The annular slide 3 has an inclined slot engaged by a set screw in the casing 1 and on rotation of the shaft 12 by the carburetter controls, the slide 3 is rotated and drawn downwards uncovering the air inlets 7. Simultaneously an inclined or wedge member 14 on the base 11 of the casing 1 engages a ball-headed screw on the disc 12a and raises it. The rotation of the disc moves the projections 25 on the cap 24 out of the recesses 26a and the cap fills the annular recess between the collars on the shaft 15, compelling the disc 12a, cap 24 and shaft 15 to move solidly together and by positively raising the member 19, actuate the fuel valve 20.

Abstract: 1488654 Electronic games device J B PALMER and G F CROFT 23 Sept 1974 [22 June 1973] 29655/73 Heading A6H [Also in Divisions G4 and G6] An electronic display device for use in playing chess, or other games, consists of a housing 10 with a playing surface 11 defined by a transparent or translucent sheet 12 bearing, for example, a chess-board pattern and overlying a corresponding array of playing cells which may be selectively energised to display a chess piece, or the like representation, and its position. The cell displays are seven-segment elements selected by using switch-board 14' to identify the piece, and by using pressure or proximity switches provided at each cell. The colour of the piece is shown by the presence or absence of a "dot" element at each cell. To move a piece, a player touches its present square first and then touches the destination square. Two such devices may be connected via a telephone line for remote play, the moves being simultaneously displayed. With an appropriate overlay 12 and a connected game programme and random signal generator, the device may be used to play games of chance involving cards or dice. Each square, or playing region, on sheet 12 is allocated an address code which is translated by the game programme into a code representing a particular symbol or absence of a symbol to be displayed at the playing regions. The electrical system for the device consists of: a) the playing cells, each of which includes circuitry for storing information relating to the progress of the game, and for automatically changing that information, and the corresponding display, in response to a direct or random selection of that or another cell, b) a timing control unit with docks for providing time-dependent control signals, and c) a master control unit which together with the timing control unit, monitor and control the device, d) a piece selector unit providing an address code and a control signal when the piece symbol selection switches 14' are operated, e) a transmitter unit for sending information relating to a selected cell or cells to a remote device, f) a receiver unit for receiving similar information from another device, g) an address unit responsive to actuation of any of the cell switches to activate that cell, and h) a piece code and display control unit for transferring information corresponding to symbols to and from the playing cells.  The circuit for each of these units is shown schematically in the drawings.
