Title: Improvements in sewing machines
IPC: D05B69/10
Filed: 1950-03-02
Abstract: 683,079. Sewing-machines. EISENBEISS, J. F. R. March 2, 1950 [March 2, 1949; Aug. 18, 1949; Feb. 9, 1952], No. 5346/50. Drawings to Specification. Class 112. In order to avoid the need for gearing to convert rotary to reciprocating or oscillating movement the needle-bar, feed-mechanism, and shuttle or looper are actuated by solenoids controlled by the movements of the needle-bar. Since the standard and arm contain no mechanism, the frame may be jointed in various ways to provide for placing the head in various positions or for moving it clear of the work, or it may be formed with interchangeable sections of different sizes. Straight needles, driving.-In the embodiments described the needle-bar is moved downwards by a solenoid and raised by a spring, the movement being controlled by an air dashpot or by electromagnetic damping means. If the needle-stroke is long, the solenoid may be divided into successively-energised sections. If the frame is constructed so that the arm or head can be moved out of operative position, the needle-bar solenoid circuit may include a contact which is broken when the head or arm is moved. Lock-stitching by shuttles.-In one form, a shuttle is carried in an arcuate holder oscillating about a pivot and provided at each end with an iron core acted on by a fixed solenoid; the solenoids are energised alternately, through contacts actuated by the movement of the holder, so that the shuttle makes a single stroke during each upstroke of the needle-bar. In another form the shuttle oscillates on a spindle geared to a relatively large wheel to which are connected respectively a solenoid-actuated rod and a return spring. Feed by dogs.- The usual feed-dog is connected to a solenoid which produces its workadvancing movement. Frames.-The head may be vertically adjustable on the arm or pivotable about an axis parallel to the arm. The standard may be provided with a hinge or hinges arranged so that the arm can be swung upwards in a vertical plane to facilitate the insertion of work and/or swung bacliwards about an axis parallel to itself to incline the needle, and it may be divided on a horizontal plane, the upper part, with the arm, being movable about a vertical axis and adjustable vertically on that axis; contacts are provided to break the needle-operating circuit when relative movement of the frame parts carries the needle out of operative position. The arm and the base may be divided at corresponding points so that a standard with longer arm and base portions may be substituted for the existing one to accommodate large work.
Patent GB-306406-A (GB)
Title: Improvements in or relating to telegraphic installations
IPC: H04L12/00
Filed: 1929-02-18
Abstract: 306,406. Siemens & Halske Akt.-Ges. Feb. 18, 1928, [Convention date]. Central-station apparatus.-In an automatic exchange system for printing or other telegraphs, the lines are cleared by a signal differing in character from the impulses used for effecting the required connections at the exchange, these latter being, however, of the same character as the message impulses. Three subscribers' sets are shown, A1 being arranged for two-way simplex working over two pairs of line-wires L1, A2 for duplex over one pair L2, and A3 for simplex working in alternate directions over one pair L3. In each case one pair of leads such as a1, b1 is allotted at the exchange for incoming signals and one pair such as d1, e1 for out-going signals. A1 calls A2 by dialling three impulses from the subscriber's transmitter S1. These are received by the receiver E2 at the exchange and are repeated by contact e2 to the stepping magnet H1, the armature h1 (shown detached) of which steps round the selector wipers i, k, l, m, n to their third contacts. On the cessation of the call' the slow-acting relay P1 comes into action and closes its armatures p1a, p1b, p1d, p1e, p1f, thus .connecting the leads a1, b1, d1, e1 to the leads a3, b3, d3, e3 respectively, so that subscriber A1 is connected to subscriber A3. The magnets Q1, Q3 are energized via the contact p1f and magnet P1 respectively, their armatures q1, q3 opening the circuits of the corresponding stepping-magnets H1, H3, so that the subsequent impulses used in signalling a message do not affect the selector mechanism. Should the subscriber A2 now call up, his switching magnet P2 will be in parallel with the magnet P1 and so will take insufficient current to operate its contacts. The magnet P1 will be unaffected by the call, however, the current through it being strong enough to hold the armatures when once these have been attracted. The line is cleared by, for instance, an alternating current of 50 cycles sent by the subscriber A1; this energizes the magnet W1 which lifts the pawls holding the wipers i - - n, so that these wipers return to their normal positions. The clearing current may be sent under the control of a switch which is automatically operated at the end of the transmission.

Title: Improvements in or relating to centrifugal fan rotors embodying airfoil blades
IPC: F04D29/68
Filed: 1958-02-19
Abstract: 843,979. Centrifugal fans. WESTING- HOUSE ELECTRIC CORPORATION. Feb. 19, 1958 [March 19, 1957], No. 5394/58. Class 110(1). In a centrifugal fan impeller comprising backwardly curved aerofoil blades, the blades have curved or rounded trailing edge portions which merge with the pressure faces of the blades, the trailing ends of the suction faces of the blades being spaced from the trailing edge portions to form therewith slots which are tangential to the trailing edge portions, and gas can be supplied under pressure into the interiors of the blades and discharged through the slots for the purpose of increasing the discharge pressure of the fan. Fig. 3 shows a fan blade in which the pressure face has a curved trailing edge 30A, and a member 34 is interposed between the edge 30A and the trailing edge of the suction face so as to form slots 35 and 36. Compressed air can be supplied from an external source in the manner described in Specification 780,464, entering the interior of the blade through a passage 27 and being discharged through the slots 35 and 36. The air blown from the slots 35 and 36 adheres by the Coanda effect to the curved surfaces of the member 34 and trailing edge 30A respectively, and the two air jets combine to form a wider single jet at an angle of between 15 and 120 degrees to the camber line of the blade. The slots preferably extend the width of the blade, and the sum of their widths is preferably between 0.5 and 10% of the chord length of the blade. The member 34 may extend all the way to the pressure face of the blade so that the Coanda effect is not used to guide the air jet blown from the slot 36. The member 34 may be omitted so that the slots 35 and 36 are replaced by a single slot. Specification 841,164 also is referred to. Reference has been directed by the Comptroller to Specification 758,906.
Patent GB-539862-A (GB)
Title: Improvements in the treatment of cellulosic fabrics
IPC: D06L1/18
Filed: 1940-03-26
Abstract: 539,862. Bleaching and washing textiles. MATHIESON ALKALI WORKS. March 26, 1940, No. 5398. Convention date, March 28, 1939. [Class 15 (ii)] A small proportion of sodium chlorite is incorporated in aqueous alkaline solutions employed at raised temperature for the treatment of cellulosic fabrics without any substantial bleaching. The process is especially applicable to the kier-boiling of unfinished fabrics, such as cotton greige cloth, in that it enables such preliminary de-sizing operations as malting, acid treatment and soaking in warm water to be dispensed with. The use of the sodium chlorite improves the absorbent qualities of the cloth, facilitates the removal of its starch content and improves the whiteness obtained in subsequent bleaching. The process is also applicable to laundering operations. In examples, (1) a cotton greige broad cloth is moistened with water and treated for 8 hours with a boiling aqueous solution containing caustic soda, sodium silicate, sodium metaphosphate and sodium chlorite, prior to the usual souring and bleaching operations ; (2) and (3) a lightweight cotton greige cloth is singed, washed with warm water and treated with a boiling aqueous solution containing caustic soda and sodium chlorite for 2 hours at atmospheric, and 10 hours at 15 lb. per square inch above atmospheric, pressure, prior to the usual washing, mercerizing, bleaching and souring operations, the proportion of sodium chlorite used in (3) being two-thirds of that used in (2) ; (4) a broadcloth is mercerized, washed and treated for 8 hours with a boiling aqueous solution, at 15 lb. per square inch above atmospheric pressure, containing caustic soda, sodium chlorite, pine oil soap and sodium silicate, prior to the usual washing, souring and bleaching operations ; (5) a similar cloth is singed, washed and treated with an aqueous solution containing caustic soda, pine oil soap, sodium carbonate and sodium chlorite, the temperature being raised to 180-190‹ F. and so maintained for 2 hours, the pressure being then raised to 15 lb. per square inch above atmospheric and so maintained for 14 hours, prior to the usual washing, bleaching and souring operations ; (6) a similar cloth is malted, washed, impregnated with caustic soda solution, treated for 10 hours with a boiling aqueous solution containing caustic soda, trisodium phosphate, sulphonated castor oil and sodium silicate and further treated for 3 hours with a boiling aqueous solution containing caustic soda, sulphonated castor oil and sodium chlorite ; alternatively sodium chlorite may be added to the first boiling liquor and the second boil dispensed with. The use of tetrasodium. pyrophosphate with the sodium chlorite is advantageous as serving to increase the brightness and absorbency of the cloth.

Title: Improvements in Milk Releasers for Milking Machines.
Inventor: DAVIES JOHN HENRY
IPC: A01J5/04
Filed: 1918-04-04
Abstract: 124,891. Davies, J. H. April 4, 1918. Cow-milkers.-A milk releaser comprises a first chamber 5 permanently in a state of vacuum, and a second chamber 8 into which the milk flows from the first chamber through a non-return valve 7, the second chamber having a main valve alternately admitting air and vacuum under the control of an auxiliary valve 32 actuated by a float 13 rising and falling with the level of the milk. The supply of air or vacuum to the second chamber controls an outlet valve 11 for the passage of the milk and the outlet valve may be connected to a third receiving chamber 16, situated if desired at a higher level or at a. distance from the main releaser and similarly connected to air and vacuum alternately under the action of the auxiliary valve 32. The milk may be delivered from the chamber 16 through an outlet valve 18 into a receptacle 20, or delivery may be made direct from the outlet 11, the pipe 14 and cap 22 being disconnected. The first chamber 5 receives the milk through a supply pipe 4 and is permanently connected to vacuum by a pipe 3. The second chamber 8 is in communication with a main valve support 54 by a pipe 12 leading to a valve opening 64. A central port 52 in the valve support 54 is connected to the vacuum in the chamber 5 through a pipe 66. A slide block 62 having a recess 63 is moved to open the port 64 to air or to place it in communication with the vacuum port 52, being arranged for this purpose between collars 61 on a piston-rod 59. The pistons 58 on the rod 59 work in cylinders 57 on the valve support, and are actuated through pipes 49, 51 by the auxiliary valve 32. The auxiliary valve 32 comprises a casing 39 secured to a boss 31 on the milk receptacle, being alined in correct position by a guide-pin 41. Passages 44, 46, Fig. 8, in the casing lead to the pipes 49, 51 respectively; a passage 42 is connected by a pipe 48 to the vacuum, port 52 in the main valve and a passage 43 admits air. The opposite cylinders 57 on the main valve support are thus connected alternately to air and vacuum according to the position of the bridge-piece 34 in the valve casing 39. The bridge-piece 34 is formed on the end of a spindle 28 passing into the chamber 8 and terminating in a forked arm 26 which carries the float 13. In the position shown, the chamber 8 is in vacuum. As the float 13 is raised by the accumulation of milk, the auxiliary valve 32 is reversed, thereby shifting the slide block 62 and opening the chamber & to air. The chamber 16 is similarly operated, being connected by a pipe 21 to a second air and vacuum port 65 in the main valve support. A cock 69 serves to disconnect the third chamber when not required. An external hand-lever is provided on the spindle 28 to permit of manual manipulation of the float. The float may alternatively be arranged in the first receiving chamber.
