Title: Adjustable elongated spray nozzle
IPC: B05B1/04
Filed: 1971-04-19
Abstract: 1342686 Spray producer USS ENGINEERS & CONSULTANTS Inc 19 April 1971 [20 Feb 1970] 23105/71 Heading B2F Spraying apparatus for use in electrolytic tinning lines comprises inner and outer elongated concentrically arranged tubes having respective lengthwise slots in their walls, a lip fixed to one edge of the slot of the inner tube and extending into the slot of the outer tube thus defining an elongated orifice and means for rotating one tube relative to the other to vary the width of the orifice. The figure shows in cross-section outer tube 12 which is closed at one end and inner tube 10 which has a fluid inlet (29, Fig. 1, not shown) at the opposite end to the closure of tube 12. Both tubes have a slot milled substantially the length of the tube and by rotation of tube 12 relative to tube 10 the size of the orifice defined by lip 19 with the slot in tube 12 may be varied. Rotation is limited by stop members in conjunction with the handle used to rotate the tube 12.

Title: Improvements in and relating to hydraulic tappets for internal combustion engine valve gear
IPC: F01L1/245
Filed: 1952-09-15
Abstract: 734,786. Valve gear. VOORHIES, C. Sept. 15, 1952 [May 8, 1952], No. 23129/52. Class 7(6). [Also in Group XXIV] A hydraulic tappet comprises a hollow plunger 17 slidable in a cam-actuated cylinder 8, the interior of the plunger being connected to the tappet pressure space through a non-return valve 23 which is arranged to contact the end of the cylinder 8 when the plunger moves down to its lowest position. Hydraulic fluid is supplied to the space 34 in the plunger when a groove 14 in the cylinder coincides with a supply port 6, air in the fluid escaping past the loosely fitting cap 28 in which the valve push rod 31 is seated or through the clearance between the plunger 17 and cylinder 8. The movement of the valve 23 away from its seat is limited by a valveretainer 20 held in position by a spring 21, preferably a dual rate spring, urging the plunger 17 and cylinder 8 apart. If the valve 23 is held open by dirt lodging on its seat, the tappet fails to operate and the plunger 17 is forced down until the valve 23 contacts the end of the cylinder 8, when the pounding of the valve on its seat due to the reciprocation of the cylinder 8 breaks up the dirt and allows the valve to seat properly and the tappet to resume operation. The port 6 and groove 14 may be arranged to coincide at the top or bottom of the stroke of the cylinder 8, or at a mid-point thereof. The valve retainer 20 may be made resilient by slits in the side thereof and the spring 21 may be arranged to grip the retainer 20 and the cylinder 8 to prevent relative rotation thereof. The cylinder 8 is provided at its lower end with a groove whereby the areas of the cylinder and plunger in contact with one another are reduced as the plunge slides into the cylinder. In a modification the hydraulic fluid is supplied by gravity feed from a space above the plunger 17. Specification 734,827 is referred to.

Abstract: 484,768. Pipe couplings. YANAGI, M. Aug. 24, 1937, No. 23200. Convention date, Aug. 24, 1936. [Class 99 (i)] A disconnectible pipe coupling comprises socket and spigot members 1, 7 with an extension 3 of the member 1 locating a number of spaced locking balls 6 which are adapted to engage recesses 8<4> in the member 7 upon axial movement of a bush 11 which is mounted on the said member 7 and is provided with a cam ring 12. The bush 11 is secured to the member 7 and prevented from rotating thereon by the engagement of spring-pressed plungers 10 on the member with axial slots 11<1> in the bush, and it is normally urged into its locking position by a coiled leaf spring 13. Fluid-tightness between the two members is effected by a U-shaped rubber &c. gasket 5 which is located in an annular recess 4 in the member 1, the recess being in communication with the interior of the member by slots 2<1> provided in said member.

Title: Improvements in and relating to apparatus for measuring the gas content of liquids
Inventor: WILLIAMS ERIC EDWARD
IPC: G01N7/14
Filed: 1953-08-22
Abstract: <PICT:0761870/III/1> In apparatus for measuring the gas content of liquids by exposing the liquid to high vacuum to extract the gases and then measuring the volume of the gases, a spray chamber 17 is provided into which a measured sample of the liquid is sprayed through a nozzle 22, and the chamber forms part of a closed system provided with valves and means for varying pressure so that the sample can be recirculated through the nozzle.  As shown the spray chamber 17 is connected to a liquid measuring chamber 14, 15 and through a receiving chamber 19 to graduated mercury manometer 25 and by flexible tube 28 to mercury reservoir 29.  In use the apparatus is first filled with mercury by raising reservoir 29 and then a known volume of liquid is introduced through tap 13 to graduation 37. Pressure is then reduced by lowering reservoir 29 and the liquid flows into receiver 19; valve 18 is then adjusted so that by raising reservoir 29 the liquid is forced through narrow bore tube 21 to nozzle 22; this operation may be repeated until no more gas is released.  The volume of the separated gas is adjusted to a known volume using one of the graduations 38, 39 on the neck of the measuring chamber and its pressure is measured on manometer 25; the gas content of the liquid may then be calculated. Preferably at least the measuring chamber is provided with a temperature control jacket. The apparatus may be adapted to measure the gases evolved in reactions, e.g. in blood tests

Abstract: 757,276. Cow-milkers. AKTIEBOLAGET MANUS. Aug. 19, 1954, No. 24151/54. Class 84. [Also in Group XXIX] An automatic cut-off valve operable on loss of vacuum in any of the teat-cup conduits of a milking machine comprises a rotary cylindrical valve member with a pair of diametrically opposite, axially-extending recesses 9 whereby a main conduit 3 is placed in communication with branches 4 leading from the teat cups when the valve member is turned through 90 degrees from the closed position shown. An extension 25 of one of the recesses 9 communicates with a passage 26 when the valve is open so that a chamber 27 enclosed by a flange 13 of the valve member is subject to vacuum resulting in the flange being pressed against a rubber washer 11 with sufficient force to hold the valve open against the closing bias of a torsion spring 16. When, due to loss of vacuum, the valve starts to close, passages 28, 29, 30 are brought into register to open the chamber 27 to atmosphere. Manual opening of the valve is facilitated by wings 21 on a cap 15 which houses the spring 16.

Patent GB-482943-A (GB)
Title: Improvements in or relating to the manufacture of moulding resins
IPC: C08G8/00
Filed: 1936-09-05
Abstract: A phenol-aldehyde resin capable of being moulded without fillers is produced from a hardenable and fusible resin, e.g. a novolak mixed with a hardening-agent, or a resol, free from water resulting from the condensation reaction, by adding thereto a small quantity, e.g. 1-5 per cent, of aniline hydrochloride and sufficient water, e.g. 10-30 per cent, to moisten the resin, and subjecting the moistened resin to a controlled mixing and heat treatment until the resin, while still completely soluble in ethyl alcohol and acetone, is no longer fusible, but is still plastic. Resins suitable for the invention are novolaks mixed with hexamethylenetetramine or methyleneaniline; partially acetylated novolaks with hardening-agents; condensation products of phenols, aldehydes and drying oils or fatty oils.  In an example, a novolak produced from phenol and aldehyde with an acid catalyst is ground with a little hexamethylenetetramine and stearic acid and melted in a calender, the rolls of which are heated with steam at 100 DEG  C. Aniline hydrochloride and water are added before or after placing in the mixing apparatus and the heating of the rolls is so regulated that the mixture melts but does not become sufficiently fluid to flow from the rolls.  When a homogeneous mixture has been formed, it is taken from the rolls and placed in a drying oven for 2-4 hours at 70-80 DEG C., the temperature being so regulated that the resin softens but does not melt.  If not sufficiently advanced, the resin may be ground, moistened with water and again worked up on a calender heated to 100-110 DEG  C.  A heat-hardenable resin may be worked up in a similar manner.  The moulding resins may be moulded at 160-170 DEG C.  Before moulding, any volatile constituents may be removed by prolonged exposure of the disintegrated resin to a current of hot air or by vacuum treatment; also dyes, pigments, plasticizers or lubricants may be added.  Specification 304,648, [Class 2 (iii)], is referred to.
