IPC: A61M5/28
Filed: 1952-07-08
Abstract: 718,837. Hypodermic syringes. COOKWAITE LABORATORIES, Inc. July 8, 1952 [July 18, 1951], No. 17200/52. Class 81(2) A tubular ampoule syringe has a needle support clipped on to its end, the needle being carried therein so that its inner end will pierce the adjacent ampoule plug. In the packed condition, the inner ampoule plug 11 is set slightly in from the end of the ampoule so as to provide a space 14 for accommodating the inner end 15 of the needle, this being supported in a boss 24 attached to a disc 21 which, in turn, is attached to the ampoule body 10 by integral resilient blades 23. The outer end of the needle is protected by the hollow plunger rod 19 which fits over the boss 24. When the syringe is to be used the plunger is removed from this position and inserted in the other end 18 of the ampoule, so as to bear against the piston plug 17. Pressure on the plunger head 26, while the members 23 are gripped between the fingers, causes both plugs 11, 17 to move forward until the inner one 11 is pierced by the needle end 15 after which expulsion of the medicament 20 proceeds in the usual manner. In another modification (see Fig. 7, not shown) the inner end of the plunger rod is widened to provide a more rigid engagement with the piston plug and the needle support has additional spring arms for engaging the step so formed, to retain the plunger rod securely when in the stored condition. If very long ampoules are to be used these may be provided at a suitable point along their length, with a tightly gripping annular rubber member which provides a finger hold during the injection.

Abstract: 169,028. Metropolitan Sewing Machine Corporation, and Weis, J. P. June 24, 1920. Gearing for stopping and starting machinery; clutches, free-wheel.- An oil cushion is provided in the stopping mechanism for the driving shaft of a sewing or other machine whereby the shaft is stopped without shock. The shaft 25<a>, Fig. 9, to be .driven has an enlarged end 91 in which are formed three equallyspaced peripheral slots 92, Fig. 11, adapted to receive three wedges 93a surrounded by a sleeve 96, having three radial holes to receive balls 99, riding in grooves in the wedges eccentric to the axis of the shaft. The shaft end 91 has an extension 108, Figs. 3. and 9, which fits with rotary lost motion within the part 103 of the sleeve 96, and both these parts carry axially projecting pins which are connected by a spring 111. The continuously running pulley 100 is provided with a ring 99a which loosely surrounds the balls 99, and while the machine is running the spring 111 holds the sleeve 96 in such angular position relatively to the shaft that the balls 99 rest on the high parts of the wedge grooves, whereby they are pressed into contact with the ring 99<a> and the pulley and shafts are clutched together. The part 103 is eccentrically grooved at 105 to provide a stop shoulder 104 adapted to be engaged by a stop finger 170, Fig. 3. carried by the stop motion control lever 144. thereby arresting the sleeve 96 and declutching the shaft. The stop finger 170 is slotted at 167 to receive the pivot pin 163 carried in the lever 144, and springs 165 urge the, finger to stopping nosition, lost motion between the pin 163 and slot 167 allowing the finger to ride on the high part of the eccentric groove 105. A brake shoe 117 is pressed on to the part 103; by the spring plunger 126 and is released, when the lever 144 is lowered to remove the stop finger 170 from the shoulder 104 by the lever 121 which is engaged by an arm 145 loosely mounted on the pivot 142 of the lever 144 and adjustable with relation to the lever 144 by means of the screw 139. The lower end of the finger 170 rests against a thimble 157 which is pressed outwardly by a spring 160 and slides in a bushing 151 screwed in the lever 144 and provided with a fixed ram 154. A recess 145a in the lever 144 holds filtering material and is supplied with oil which passes through the passages 149, 150 and ports 155. 156 in the bushing to the interior of the thimble. When the finger 170 engages the shoulder 104, its lower end pushes in the thimble 157 which gradually closes the ports 156 whereby an oil-cushioning effect is produced and the shock of stopping the shaft is absorbed. Oil is supplied by a small pump in the base of the machine through the pipe 11 to a pocket in the housing a<1> and percolates through to the balls and wedges of the clutch, overflowing through the pipe 90 to the recess 145a in the lever 144.

Abstract: 1332542 Linkwork LANDIS & GYR AG 26 May 1971 [24 June 1970] 17325/71 Heading F2K An electro-thermally length controlled link, i.e. push-rod assembly in an actuator for mechanically adjusting members such as valves or air flaps &c., includes a resetting device operated automatically in the event of a break or substantial fall in an operating network voltage to return the member to its starting position, and comprises co-axial push rods 3, 5 interconnected by a lost motion arrangement in which a collapsible spring bellows 17 is connected between the sealing end 16 of the output push rod 5 and a cylinder 14 seated by a cover 15 on the input push rod 3 with the relative axial movement of the push rods 3, 5 being limited by a stop sleeve 18 fast with the cylinder 14 which is axially slidable in a bore 4 of a housing sleeve 19, the cylinder 14 being connected by a capillary tube 7 to an electrically heated vaporizer 6 which, during operation, is thermally controlled at a constant temperature by a temperature sensor 20 and regulator 21, the cylinder, tube and vaporizer 14, 7, 6 all being fluid filled and arranged such that before becoming operational, i.e. when the vaporizer 6 is inoperative and cool, the sealing end 16 is in contact with the cover 15 so that the length of the link, i.e. push rod assembly is at its maximum. As soon as the heating winding 13 of the vaporizer 6 is connected to the operating network voltage, the temperature in the vaporizer 6 rises forming a vapour bubble whereby the bellows 17 is compressed to downwardly move the push rod 5 against a spring bias of the mechanically adjustable member (not shown) so that during normal operation, with the vaporizer 6 heated continuously at constant temperature, the sealing member 16 is precisely seated on the sleeve 18 so that the length of the push rod assembly is at its maximum and the adjustable member (valve or air flap) can be moved into any desired setting by a force acting via the push rod 3, the sleeve 14 bellows 17 and push rod 5 moving up and down as a unit with the push rod 3. If a drop or break in the operating voltage occurs the vaporizer housing 9 rapidly cools reducing the vapour pressure to enable the bellows 17 to expand to its rest position relieving the push rod 5 of load whereby the adjustable member returns to its starting position irrespective of the axially adjusted position of the push rod 3.

Title: Improvements in or relating to cracking oils and tars
IPC: C10G11/02
Filed: 1926-07-20
Abstract: 267,776. Soc. Luxembourgeoise des Hydrocarbures, and Brimeyer, F. July 20, 1926. Mineral and tar oils. - Oils are cracked under their own pressure by first vapourizing them, cracking the vapours, and then hydrogenating the product by nascent hydrogen. The oils are supplied through a valved conduit 39 to a vessel 1 where they are cracked under their own pressure, the vessel 1 being heated by burners and gas conduits 10. The residues are collected in a receptacle 9 and discharged through a valve 36. The cracked vapours are passed through a dephlegmator 5 to heat exchangers 6, 7, the latter of which is cooled by water entering and leaving conduits 33, 34, while the former is cooled bv the condensate collected in a tank 8 from the condensed vapours produced in the heat exchangers 6, 7, this liquid being also used to cool the diphlegmator 5. The condensates being thus re-evaporated pass through a pipe 2 and super heating coil 3 to one of the hydrogenating chambers 31, 31<a> containing a metallic filling where they are hydrogenated by a stream of nascent hydrogen produced by the reduction of sulphuretted hydrogen by the metallic mass. The chambers are used alternately for hydrogenating the vapour and for forming sulphuretted hydrogen, the metallic mass being alternately converted to sulphide and reduced to the metallic state again. The burnt gases from the burners 10 pass through the heating tubes of a boiler and economizer 2 and channels 13 into the hydrogenation towers which are thus heated, the gases finally escaping by a pipe 16 to a tower 18. Additional burners 12, 14 may be used if required.
