Abstract: 104,903. Loeb, R. March 20, 1916. Eyelet-hole sewing-machines; needles, vibrating; presser-bars, lifting; work supports.-In a machine for forming eyelets of shapes other than round, the work is clamped between a rotatable presser-foot and a turntable, and the position of the stitch-forming means is controlled by a cam, corresponding in shape to the eyelet required, carried by the presser-foot. The presser-foot comprises a ring 57, Figs. 4 and 6. supporting two rings 58, 59 by clips 60 having flanges entering an annular recess in the ring 59, which carries an annular rubber ring 62 and runs on ball bearings on the ring 58 pressed down by a spring 72. The turntable comprises a ring 65 mounted on ball bearings in a recess in the work-plate 33 and secured by a clamping- plate 68. The ring 59 is provided with the control cam 73, and with set-screws 91 for positioning the work. The needle-bar 3, Fig. 3, is reciprocated through a sleeve 6 pivoted to the head of the machine at 7 and vibrated by a. spring 23 and a pin 19, which is acted on by a two-armed lever 18, Fig. 4 carrying adjustable screws 20, 21 and secured to a rock-shaft 17, which is oscillated by an arm 16 carrying a roller 15 and a cam 14 on a countershaft 10 driven from the main shaft. The arm 16 is in two hinged parts normally rigidly held together by a sliding pin, which is withdrawn when it is desired to stop the needle vibrations for forming tying stitches at the end of an operation. Interposed between the screw 21 and the pin 19 is the wedge-shaped part 75 of a rod 80, which is slidable in an arm 81 supported by the shaft 17, and bears at one end on a leaf spring 82 and at the other end on an arm 77a secured to a shaft 77 mounted in a bearing 76 and carrying at its lower end an arm 78 with a roller 79 in contact with the cam 73 on the presser-foot. As the work is rotated by the operator, and with it the presser-ring 59 and turntable 65, the position of the rod is varied through the connexions described, to vary the field of needle vibrations in accordance with the shape of the cam and desired eyelet. In the form shown in Fig. 3, the presserbar 38 is mounted in the end of a bracket 35 secured to an extension of the work-plate 33, and has a slot engaged by the end of a bar 36 pivoted to the bracket at 37 and pivotally connected at its other end to a rod 52, which is surrounded by a spring 55 tending to press the presser-foot down in the work. The presser-foot is raised by a lever 49 having a pin 48 adapted to be raised by an arm 47 on a longitudinal rockshaft 45 carrying at its rear end another arm 44, which is depressed by an arm on a transverse shaft with a knee-piece. In a modification, the presser-bar is mounted in the head of the machine and carries an arm bv which it is raised against the actuating-spring through means under the control of the operator

Title: Automatic electronic device for controlling taps
IPC: E02F9/20
Filed: 1973-01-26
Abstract: 1416262 Transistor delay circuits AIDEN KK 26 Jan 1973 [27 Jan 1972 1 Feb 1972 18 April 1972 20 April 1972 12 May 1972 16 May 1972 23 Aug 1972] 4123/73 Heading H3T [Also in Division G1] A tap is caused to open and close automatically under the control, particularly, of a photoelectric device, a timing apparatus being provided to close the tap when it has been open for a predetermined time.  Photo-electric apparatus.-Light source (21) produces a beam (22) projected across an area into which the hand may be passed to present the beam from reaching photo-diode (17) (after reflection at mirror 19). Infra-red transmitting filters (9) are provided. Alternatively source and detector are on either side of the gap. Circuit.-The detector 27 may be connected in a control circuit shown in Figs. 4, 5. Interruption of the beam causes the detector impedance to rise and switch the trigger circuit 36. After shaping by Schmitt trigger 35, the pulse is used to switch bi-stable 33, which is normally in a state so as to maintain relay RY in circuit 28 de-energized and thus the tap closed. On switching, bi-stable 33 applies a pulse to the trigger of the thyristor SCR in 28 to energize the relay of magnetic value MGV (29) to open the tap. When the head is removed, to cause illumination of the detector once more, the bi-stable stays in its switched state, to maintain water flow. However, timing circuit 32 has been triggered and after the time set by resistor R4 and capacitor C3, transistor PUT is turned on to provide an input at 37 to trigger circuit 36 and switch bi-stable 33 back to its original state and close the tap. Closing of the tap before the end of the predetermined time is accomplished by interrupting the beam again. In an alternative circuit, a latching relay replaces the bi-stable circuit, Fig. 6 (not shown). Other types of electromagnetic radiation may be used, e.g. X-rays and use of ultrasonic waves is also suggested.

Abstract: 740,674. Starting oil engines. BOSCF ,GES.. R. Feb. 12, 1954 [Feb. 14, 1953] No. 4133/54. Class 7(3) [Also in Group XXVI] A stop 18, setting the normal maximum fuel supply position of a fuel injection pump control rod 7 controlled by a centrifugal governor 3 through a lever 6 pivoted at 9 on a manually. actuated adjusting lever 13, is pivotally mounted at 19 and is connected to a lever 22 which is acted upon by the governor 3 when the engine is at rest or turning at speeds up to starting speed to move the stop 18 sideways to permit the control rod 7 to move to a position beyond the normal maximum fuel supply position to supply excess fuel for starting. The lever 22 is normally held by a spring 26 against a stop 27, whereby the stop 18 is positioned to engage a step 16 on the rod 7 to limit the movement of the rod 7 to the right. - When the engine is at rest or turning slowly, the governor springs force the governor sleeve 4 against the end of the lever 22 and rotate it clockwise to move the stop 18 downwards out of engagement with the step 16 but positioned to engage a second step 17, which permits the rod 7 to be moved by the control lever 13 to the excess supply position for starting. When the engine fires and rotates at speeds equal to and greater than idling, the governor sleeve 4 is withdrawn to allow the lever 22 and stop 18 to return to their normal position.

Title: Improvements in the production of porous materials from thermoplastic high molecularweight addition polymers
IPC: C08J9/12
Filed: 1951-02-22
Abstract: Porous materials are produced by homogeneously dispersing in a monomeric polymerizable substance, or in a solution of a high polymer material in a monomeric polymerizable substance, a volatile organic liquid in which polymers of the monomer are insoluble or only swellable, polymerizing this mixture at temperatures below the boiling-point of the liquid, and heating the resulting mass to a temperature above the boiling-point of the liquid.  Polymerizable substances specified are vinyl esters of organic acids, vinyl ethers, isobutylene, styrene, acrylic compounds, methacrylic compounds, such as methyl methacrylate, vinyl and vinylidene chlorides, and vinyl carbazole.  High polymeric materials which may be dissolved in the monomeric substances are polyisobutylene, polystyrene, and polymethyl methacrylate.  Liquids suitable as blowing agents are pentane, hexane, heptane, petroleum ether, spirocyclane, cyclopentane, cyclopentadiene, acetone, methyl alcohol, methyl and ethyl formates and acetates, dichloroethylene, isopropyl chloride, propionaldehyde, and dipropyl ether.  The polymerization may be carried out with the aid of benzoyl peroxide as a polymerization catalyst.  The blowing step may be carried out in water, in another liquid which does not dissolve the thermoplastic mass, or in a moist atmosphere, if desired while employing an external pressure of more than one atmosphere. The porous products may be used as cork substitutes, as electrical insulating materials, as packing, padding, shock-absorbing and floor and wall covering materials, and in the manufacture of shoe parts, sun helmets, hat bands, pin cushions, and dolls and fish and like toys.ALSO:A homogeneous composition of polystyrene and petroleum ether is placed in a closed mould in which a sieve constitutes one or more of the mould walls, and is then heated to expand the polystyrene to conform to the shape of the mould.
