Title: Improvements in or relating to electrically-operated make and break devices for use in horns or warning devices for vehicles, or for use in electric bells, interrupters for spark coils, and the like
IPC: H01H51/34
Filed: 1924-11-14
Abstract: 245,556. Fuller's United Electric Works, Ltd., and Welch, A. P. Nov. 14, 1924. Electromagnetic interrupters; diaphragm horns.-In interrupters for electric horns, bells &c., an auxiliary winding a connected at its ends to the make and break contacts c, d is provided on the armature b. When the contacts c, d are closed, the winding a is shortcircuited, and current flows through the winding f of the electromagnet e. The armature b is thereby attracted, contacts c, d separate and current flows through the winding a producing a field opposing the field of the magnet e and causing a more rapid return of the armature b. Sparking at the contacts c d is also eliminated. The invention is shown applied to an electric horn.

Title: Improved method of and apparatus for turning welts of full fashioned stocking machines
IPC: D04B11/32
Filed: 1934-09-24
Abstract: 422,626. Knitting. WILDMAN MFG. CO., Norristown, Pennsylvania, U.S.A.- (Assignees of Howie, K. ; Norristown, Pennsylvania, U.S.A.) Sept. 24, 1934, No. 27413. Convention date, Nov. 10, 1933. [Class 74 (ii)] Relates to welt-turning devices for fullfashioned knitting-machines. When the welt is finished, the welt bar A is placed by hand on a pivoted bar 12 with the welt hooks b directed to the space between the needles and the presser bar and in line with the spaces between the sinkers and dividers. The bar 12 has pockets 12<f> to receive the reduced ends of the welt bar. Under pressure of the operator's hand, the welt bar is rocked to position the welt hooks relative to the needles. The backs of the hooks b are formed with grooves or eyes to engage with the needle hooks. When the bar 12 is pushed down as far as it will go the welt hooks arrive in position with their eyes close to the upper ends of the needles and in line therewith. The operator now turns the machine by hand until the needles stand at their highest position, moves the welt bar forward to bring the hooks parallel to the needles and pushes the loops down over the needles as far as the welt hooks permit. The welt bar is then disengaged from the fabric. Specifications 396,280 and 411,517 are referred to.

Abstract: 519,335. Igniting oil burners. BOHN, E. Sept. 20, 1938, No. 27455. Convention date, April 9. [Class 75 (iii)] A conductive ignition cartridge 4 is mounted in a holder 3 connected to a spring-pressed rod 5 in a carrier 1 so as to engage the cartridge with the pin 19 of a bow-shaped conductor 18 to'complete an electric circuit, the rod 5 being adapted to be retracted against the spring 8 to withdraw the cartridge from the pin 19 and thereby form an arc or spark gap for igniting the cartridge. As shown, the holder 3 and the conductor 18 are connected respectively by wires 20, 21, with contact plugs 22, 23, the rod 5 comprising an insulating member 27. The carrier 1 is inserted in the inlet 40 of the combustion chamber, thereby opening a spring-pressed door 45, and the plugs 22, 23 are engaged in contact sockets 42, 43 connected through an inductive resistance with a current supply, a guide pin 54 being provided to engage in a hole 53. The rod 5 is retracted by an arm 11 operated by rotating a wheel 10. The cartridge is rendered electrically conductive by adding metal dust to the priming composition 24 or by means of a conductive sleeve. The priming composition is provided with a readily inflammable head 25 and preferably separated from an incombustible base 26 by an intermediate layer 28. The sockets 42, 43 and the inlet 40 may be covered by discs 49, 50 secured to a pivoted arm 48, by screwing a spindle 51 into a hole 53. In modifications, the rod 5 is retracted automatically on opening the fuel valve by means of an electromagnet or a mechanical connection.

Title: Pumping device for promoting a patients breathing
IPC: A61M16/00
Filed: 1972-06-13
Abstract: 1391069 Respiratory apparatus SOXIL SpA 13 June 1972 [15 June 1971] 27486/72 Heading A5T [Also in Division Fl] A motor driven device for actuating a patient's breathing comprises a bellow-type pumping assembly 12 having a stationary end portion 14 and a reciprocating opposite end portion secured to a movable plate 16 pivotally supported at 18, and a mechanism including a connecting rod 38 having one end pivotally connected to the reciprocating end portion at 32 and the other end pivotally conected to a component 78. The component 78 is attached to an arm 44 and the position of the said component may be varied along the arc-shaped groove 42 in the arm 44. The centre of the arc-shaped groove 42 is at the pivotal axis of connection 32, so that although the maximum volume of the chamber may be altered by adjusting the position of the component 78 the minimum volume remains unaltered. The arm 44 is pivotally connected to a shaft 46 at 84, the shaft being supported by rigid supports at 48 and 50. The arm 44 is secured, by means of a tubular member 62 on the shaft 46, to another arm 64. The arm 64 forms the driven component of the crank driven by the motor 74. The connecting rod 38 consists of two parts telescopically fitted together and a spring 60. A peg 56 in the part 52 and projecting through the part 54 prevents the two parts coming apart. This system allows for the pressure in the chamber to build up to a given value before being pumped to the patient. The crank and the arm 64 are arranged such that as the motor flywheel 72 rotates at a uniform speed the arm 64 is caused to oscillate through a given uniform amplitude and such that the stroke of the motion closing the bellows is approximately one/third of the total time of a cycle of the pump. Adjustment of the position of the component 78 on the arm 44 can be made while the device is operating as the component has a threaded bore engaged by a threaded bar 76 rotatably supported by a block 92 having a part 94 rotatable about the said shaft 46. The bar 76 is secured to a bevel gear 80 in mesh with another bevel gear 82 rotatable about the shaft 46 and is connected to gears 86 and 88 the latter of which may be rotated by a control shaft having an end 90 to which may be attached a handle wheel. The pumping assembly is complemented by a valve 96 in an exhaust duct from the patient and having a spring loaded valve member (110) and by a mechanism including a cam follower 100 cooperating with a cam surface 102, 102' provided by the contour of the crank flywheel 72. The valve mechanism acts through a rod 116 to open and close the valve member (110) against a valve seat (108).

[Classes 78 (iii) and 78 (iv)] The body of a vehicle is supported from the chassis by means of a pair of guide members mounted at each end of a transverse shaft which is attached to one girder of each pair and engages a slot in the other, the girder members of each pair being arranged for relative pivotal motion providing a scissor-like action by which the body is raised until, at a predetermined point, the shaft slides in the slots so that continued motion of the girder members attached to the shaft causes the body to tip. As shown, the body 5 of a vehicle is supported from the chassis 1 by members 6 pivoted at 11 to longitudinals 5a of the body and sliding on rods 12 secured in blocks 13 on the chassis, and by members 6a pivoted to blocks 9 on the chassis and sliding between pairs of stops 10 on rods 10a secured to the body. The members 6, 6a are pivoted together by a shaft 7 secured to the members 6a and engaging at its ends 7a in slots 8 in the members 6. The slots 8 extend parallel to the edges of the girders 6 for most of their length but are inclined to those edges at their ends. As the shaft 7 is raised by a hydraulic ram 17, the body is raised until, when the girders 6, 6a reach a predetermined inclination, the ends 7a of the shaft 7 move along the slot 8 to tip the body as indicated in broken lines. The ram 17 is preferably of the type including two pistons, one sliding within the other and being brought into operation at the end of the raising motion when it is desired to tip the body. The girders 6 may be placed inside the girders 6a and the body may tip in the opposite sense from that shown.
