Title: Improvements in and relating to Stop-motions of Looms.
Inventor: SYKES JAMES
IPC: D03D51/00
Filed: 1917-01-26
Abstract: 107,351. Sykes, J. Jan. 26, 1917. Picking-motions.-For disengaging the picking- mechanism when the loom is stopped by the weft stop-motion, two approximately vertical levers are fulcrumed on the same stud, one lever being engaged by the weft-stop bolt and the other controlling the picking-clutch, and an arm of lever mechanism on the setting-on plate normally rests between the vertical levers and is adapted to transmit the action of the weft-stop bolt to the setting-on rod to stop the loom and to the picking- clutch to disengage the picking-mechanism, which may be kept out of action as long as desired when the loom is re-started. On failure of weft, the weft-stop bolt B engages a projection C on one vertical lever D and through a lever H, pivoted on a stud J on a lever K fulcrumed at L on the setting-in plate M, moves the other vertical lever F to put the picking-motion out of action, the lever K being simultaneously moved to disengage the setting-on rod A from its notch to stop the loom. A spring-actuated catch R on the plate M locks the lever H and thus keeps the picking- motion out of action until the tail V of the lever H is depressed by a hand-operated spring- controlled lever T, T' on the handle A. When the handle A is moved into position to start the lcom, the picking-motion is not put into action until the lever T is operated so that the lever H clears the catch R, and, so long as the lever H is kept raised, the weft-stop bolt cannot operate to stop the loom or to disengage the picking-motion since the lever H is capable of movement relative to the lever K except when in its lowered position, in which it fits between lugs N on the lever K.

Title: A method of preparing acetylene for an?sthetising purposes
IPC: A61K31/01
Filed: 1927-01-17
Abstract: 264,826. Boehringer, C., (trading as Boehringer Sohn, C. H.). Jan. 25, 1926, [Convention, date]. Inhalations.-The process for preparing methylene for use as an anµsthetic, described in the parent Specification, is modified by using solid adsorbent materials such as active charcoal or silica gel, for the purpose of extracting acetone or other solvent vapour and also for simultaneously removing residual toxic impurities if the technicadly-purified gas is employed. The removal of the toxic impurities is facilitated by the use of adsorbent materials of an acid character, or by materials that have been subjected to a preliminary treatment with acids or acid substances; it is advantageous to employ dry adsorbents and pre-dried acetylene; and the adsorbent materials are conveniently regenerated by treatment with acid such as warm gaseous hydrochloric acid. The bulk of the solvent vapours may be extracted by a preliminary washing with water. The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of solid adsorbent materials for removing the toxic impurities present in the acetylene, This subject-matter does not appear in the Specification as accepted.

Abstract: 1,117,835. Slitting tubular film. E. I. DU PONT DE NEMOURS & CO. 10 Jan., 1967 [11 Jan., 1966], No. 1351/67. Heading B5B. Continuous tubing of polymeric material and having a circular cross-section, is converted into a tube of substantially rectangular crosssection, and then into at least two flattened films of different width, by advancing a tubular film 36, of circular cross-section, over apparatus comprising, a rigid supporting structure 32 and substantially delta-shaped formers 34 connected to the said superstructure by brackets 44. Movable slides 38 operated by hand wheels 40 enable a blade 42, connected to said slides, to be variably positioned across the film width. Additionally, movable slides 48, operated by hand wheels 50 permit lateral adjustment between the two formers to accommodate varying diameters of tubing. The substantially deltashaped formers have regular extensions of different length which serve to unfold the slit sections into flat pieces of film, the slitting means being situated between the extensions of the former, and closer to the shorter extension. The tubular film is converted from one of circular cross-section to one of substantially rectangular cross-section by drawing it over a shaper comprising the upper ends of the extensions of the substantially delta-shaped formers. In an example the process of the invention is applied to a polyethylene film.

Title: Indexing mechanism
Inventor: HUNTLEY ERIC JOHN
IPC: B23Q16/00
Filed: 1965-01-13
Abstract: 1,129,372. Hydraulic apparatus. JAMES ARCHDALE & CO. Ltd. Jan. 6, 1966 [Jan. 13, 1965], No. 1482/65. Heading F1P. [Also in Division B3] A mechanism for indexing a machine tool table 10 comprises two rotary hydraulic motors (not shown) operable to drive the table from one position to another at a speed determined by the displacement from a datum position of a plunger 24 forming part of an hydraulic or electro-hydraulic motor speed control, the displacement being normally controlled by a cam 32 driven independently or by the table, but arranged to be over-ridden as the table approaches its desired position by the cooperation of a stop 37 on the table and a lever 38. The cam 32 moves the spring-loaded plunger 24 through a lever 36 until over-ridden by the lever 38. The action of the stop 37 on the lever 38 ensures that the plunger 24 is moved to the datum position to thereby accurately arrest the table in the desired position. The lever 38 is flexible in a direction parallel to its axis of rotation whereby operation of a pneumatic piston and cylinder unit 4 enables the lever to be moved out of engagement with the stop 37 to cause movement of the plunger from its datum position and consequently initiate movement of the table to its next position. The electro-hydraulic speed control, Fig. 5, for the motors 13, 14 driving the table comprises a linear differential transformer 21 which provides a signal proportional to the displacement of a core 22 carried by the plunger 24. The signal is fed to a valve 18, controlling the supply and exhaust of fluid to the motors, through a circuit including a mixer 29 adapted to modify the signal in accordance with feedback signal emanating from a tachogenerator 30 driven by the motors. In a modification the speed control is purely hydraulic and comprises a four-way valve responsive to the position of the plunger.

Title: Variable displacement pump
IPC: F04B49/08
Filed: 1976-01-16
Abstract: 1517644 Valves ROBERT BOSCH GmbH 16 Jan 1976 [16 Jan 1975] 01778/76 Heading F2V [Also in Division G3] An annular member 13 determining the stroke of delivery elements 12 of a variable displacement pump 10 is adjusted by pistons 14, 15 of unequal area bearing on diametrally opposed points of the member 13, the piston 15 of smaller area being permanently acted on by the pump output pressure, whilst a cylinder 16 receiving the piston 14 of greater area is connected via a duct 38 to a control valve 28 having a slide 31 for connecting the duct 38 with the high or low pressure side of the pump, the slide being formed with three annular surfaces 45, 46 and 47, of which the surfaces 45, 46 are between the duct 38 and an inlet of a duct 40 connected to the high pressure side of the pump, and are formed as throttles. These throttles may be formed as flats (48), (49), Fig. 2a (not shown), on the annular surfaces 45, 46 or by the surfaces being of less diameter than bore 30 of the valve; the throttle formed by the surface 45 has a greater flow area than that formed by the surface 46. Pump outlet pressure acts via the duct 40 and an axial bore 43 in the slide 31 on the right hand end (as shown) of the slide, while the pressure downstream of a throttle 23 acts on the left hand end of the slide, as does a spring 34; at equilibrium the slide is positioned with the surfaces 46, 47 on either side of the duct 38. The spring 34 bears on a plate 35 which has a slight clearance in bore 32, thereby damping movement of the slide. A rise in pressure in duct 22, caused by restriction of the throttle 23 or by variation in a load connected at 24, thus shifts the slide 31 to the left, connecting the cylinder 16 to the low pressure side of the pump so that the pistons 14, 15 move to reduce the displacement of the pump, so that its output pressure falls and the slide 31 returns to its equilibrium position. Likewise a fall in the pump output pressure causes the slide to shift to the right, so that the annular surface 46 no longer throttles the flow of fluid to the cylinder 16, and the piston 14 is moved to increase pump displacement. In a modification, Fig. 4 (not shown), the axial bore 43 opens between the annular surfaces 45, 46, so that flow therethrough is throttled by the surface 45; also, a fixed throttle (62) is provided in the duct 38.
