Abstract: 863,537. Dispensing measured quantities of liquid. COUNTY LABORATORIES Ltd. Dec. 8, 1959 [Sept. 16, 1959], No. 31590/59. Class 106(5) A dispenser for delivering measured quantities of liquid comprises a collapsible container 1 having a dispensing chamber including a measuring cup 3, a tube extending from near the bottom of the container into the cup so that, when the container is squeezed, liquid is forced through the tube into the chamber, the size of the measuring cup and the position of a discharge opening or openings 8 in the tube determining the measured quantity of liquid, and an outlet 11 through which the liquid is discharged from the chamber. The measuring chamber 3 is press-fitted into the neck 2 of the container, which is of a flexible plastic material, such as polyethylene, and is formed with a tube 5 provided with a plug 6 having three spaced slots which form the outlet openings 8; an extension tube 9 extends from the tube 5 to near the bottom of the container. A transparent cap 10 forms the remainder of the dispensing chamber and is screwed on to the neck 2 of the container. In operation, the container is held in the upright position and squeezed, thereby forcing liquid into the dispensing chamber and thus filling the measuring cup, any excess liquid returning into the container through the openings 8 and the pipe 9; the container is then inverted and the liquid dispensed through the outlet 11. The outlet is closed when not in use by a screwed cap 12.

Abstract: 312,376. Hesselman, K. J. E. Nov. 26, 1927. Cylinders receiving liquid fuel.-In an engine, of the kind described in Specifications 282,731 and 282,735, and in which liquid fuel is injected into an air mass rotating about the cylinder axis, or an axis parallel thereto, and the mixture is ignited by a timed igniter, the fuel pump has a variable stroke and delivery period so that the engine may work efficiently under different load conditions. The air is admitted by a valve 5 having a baffle 7 and if the arrangement of the fuel nozzle 4 and igniter 9 is, either (a) as in Fig. 2, or (6) as in Fig. 4, the corresponding control of the fuel pump provides that, in (a) it always concludes, and in (b) commences its stroke at a fixed point in the cycle. A projection 8 from the piston protects the igniter and prevents the mixture from contacting with the cool cylinder wall. The fuel pump may be actuated by an axially displaceable cam-shaft having differently-shaped cams.

Title: Flexible stainless steel sutures
IPC: D07B1/16
Filed: 1962-08-20
Abstract: Surgical sutures having desired flexibility and strength are made from at least 19 stainless steel filaments, each having a diameter not greater than 0.0018 inch.  Small gauge sutures may be made, for instance, from nineteen filaments each of 0.0012 inch diameter, this being given a twist of twelve turns per inch, but larger diameter sutures are preferably made by twisting a number of filaments together to form a strand and then twisting several strands together to make the finished suture, the twist of the strands being opposite to that of the filaments.  Such a wire is cleaned anodically and may then be encased in polytetrafluorethylene, which may be done by wrapping a strip of a film of this material around it and then passing it through a heating device to fuse it into a unitary whole. The suture may be cut by means of the closely spaced electrodes while a current is passed between them.  This cuts the wire by melting it and results in fusing of the ends so that untwisting is prevented. It also leaves an end which may be conveniently inserted into the end of a surgical needle, where it is secured by crimping.ALSO:Surgical sutures made from stainless steel wire are given the desired flexibility by being made from at least 19 stainless steel filaments, each having a diameter not greater than 0.0018 inch.

Convention date, Dec. 7, 1935. [Class 38 (v)] The operating spindle 7 of a rheostat or like regulating device 2 has a non-circular part 7a which is slidable but not rotatable in an opening in the rotor 6 and is extended to carry a plate 8 engaging a forked operating member 11 of a switch 10. Rotary movement of the spindle 7 operates the rheostat while axial movement operates the switch 10 without altering the setting of the rheostat. Play between the spindle 7a and rotor 6 is reduced by the introduction of leaf springs 12 or a packing of felt or cardboard. In a modification, the spindle is rigidly fixed to a broad leaf spring connected to the rotor 6 and which thus allows axial movement but no rotational movement.

[Class 7 (iii).] In a fuelinjection pump the plunger 8, Fig. 4, is depressed in the barrel 9 by the action of pneumatic or mechanical power on a piston 4 against the action of a spring 6. F u e I flows from the suction chamber 1 to the pump chamber 14 through a passage 15 in the plunger 8 and is trapped between the plunger 8 and a plunger 10, which is pressed downwards against the action of a spring 12 until the discharge passage 16 is uncovered. The upward movement of the plunger 10 and thus the amount of the charge, is limited by an adjustable slotted wedge 13 engaging the head 11 of the plunger. The rod 3 of the piston 4 has an oblique portion 3<1> engaging a block 2 to which the injection valve 17 is secured. When the valve 17 is moved to the right fuel is discharged through the passage 16 and grooves 22, 23 in the valve. Simultaneously compressed air is discharged through passages 21, 19, 20. In a modification, Fig. 14, the plunger 8 is integral and coaxial with the injection valve 17. Fuel enters the pump chamber 14 through a port 24 and is discharged through passages 25, 25<1>, 23. Simultaneously compressed air is discharged through passages 21, 19, 20. The chamber 14 is formed between a shoulder on the plunger 8 and a sleeve 10<1> pressed upwards by a spring 12, the upward movement of the sleeve being limited by a wedge 13.
