Title: Air sterilizing plant
IPC: F24F3/16
Filed: 1972-03-22
Abstract: 1349116 Air conditioning; air heaters QUEPOR SA 22 March 1972 [1 April 1971] 13289/72 Headings F4V and F4S Air to be sterilized is passed by a blower 1 through a filter 2 into a heat exchanger 3 and into an air heater 4 where the air is sterilized. The sterilized air then passes back through the heat exchanger 3 and through a cooler 6 before being utilized. The heater 4 is heated by electrical resistive elements 5, and situated in the heater between the elements 5 and the air outlet of the heater, is a filter 19 of sinterized steel which is heated to the sterilization temperature. The heater 4 comprises a cylindrical shell 14 having an outlet 16 in the side wall. An inlet 15 is provided in a plate 17 which closes the bottom of the cylinder, while the heating elements are supported by a plate 18 closing the top. The resistors are arranged in a first group 51 surrounding the inlet 15 and a peripheral group 5<SP>11</SP> which are surrounded by the filter 19. The incoming air flows axially through resistors 5<SP>1</SP>, and is then forced to flow radially through the resistors 5<SP>11</SP> and the filter 19 to the outlet 16. In a second embodiment (Fig. 4, not shown) the groups of resistors are separated by a metal cylinder, and the filter is arranged in a second cylindrical shell. In this embodiment the air passes axially through both groups of resistors, into the second cylindrical shell, through the filter to the outlet.

Title: Improvements in the treatment of rubber latex
IPC: C08C1/15
Filed: 1940-08-21
Abstract: 551,646. Treating rubber latex. WALSH, C. L., and NEWMAN, A. A. Aug. 21, 1940, No. 13296. [Class 70] Rubber latex is mixed with a colloid of acid reaction derived from the flesh of vegetable matter such as plants of the Agave family or Phormium Tenax as described in Specifications 517,729 and 532,877. On standing a semicoagulated mass rises to the surface. The mass after separation of the serum may be again dispersed by treatment with ammonia or may be completely coagulated and rendered irreversible by kneading, rolling or other mechanical treatment. Fillers and vulcanizing agents may be added to the semi-coagulated mass. The colloid may be used in admixture with pectin or pectic substances, alginic acid or its salts, gelatinous substances extracted from seaweeds, laminariae, flax, hemp &c. or plant extracts normally used for creaming rubber latex. Specification 542,939 also is referred to.

Abstract: 553,375. Knitting-machines. MELLOR BROMLEY & CO., Ltd., BROMLEY, T. C., and SHORTLAND, A. Oct. 17, 1941, No. 13361. [Class 74 (ii)] The catch bar of a straight-bar machine comprises two separately movable parts 10a, 10b, a front part for engaging in front of the sinker butts to retract them and a rear part for engaging the dividing sinkers to advance them. The arrangement renders unnecessary the rising and falling movements of the catch bar. In one form, Fig. 1, the parts 10a, 10b are operated by separate cam-engaging levers 17, 18. The rear part 10b may have a lip engaging in front of the dividing sinkers 13" so that the dividing sinkers are at all times controlled by the part 10b. In a modification, Fig. 5, the rear part 10b is operated by a cam-controlled lever 28, and movement is transmitted from the rear part 10b to the front part 10a through one or more friction boxes 26. The amplitude of the movement of the front part 10a is determined by stops, and during the retracting movement the front part 10a may be positively connected to the rear part by a pivoted member 33 mounted upon the lever 28. The member 33 engages a rod 34 to release it from the front part 10a.

Abstract: 852,127. Discharge tubes. EITEL-Mc- CULLOUGH Inc. April 28, 1958, No. 13383/58. Class 39(1). [Also in Group XXXVI] In manufacturing a discharge tube having a plurality of envelope sections, the sections are separated by metallic bonding material so formed as to hold the ends of said sections apart and provide exhaust passages between them to allow evacuation or gas-filling, which is carried out in an enclosing chamber, the bonding material then being fused to close the passages and effect a seal. The envelope parts 1, 2, 3, 4, 5 may be ceramic, which are metallized, and then brazed or soldered together across interposed shims 6, 7, 8, 9, in known manner. The rings 15 of brazing material, placed on either side of the shims, are corrugated or have some other irregular shape, so that when all the envelope parts are assembled inside an enclosing chamber 30, the device may be freely evacuated by evacuating the chamber. The brazing material is then melted to form a completely sealed envelope by a heating coil 27 also positioned within the chamber. Specifications 782,102 and 803,225 are referred to.
Patent GB-134065-A (GB)
IPC: B64C35/00
Abstract: 134,065. Short, H. O. Nov. 13, 1918. Blast apparatus, injector; controlling action.- In apparatus for inflating aeroplane floats, upon the aviator turning a cock in the small high-pressure pipe connected to the supply cylinder, the high-pressure air passes the connexion 5, closes the spring-pressed valve 6 leading to the atmosphere, and enters the cylinder 3 which is connected to an injector 17 by a pipe 18. The air in the cylinder 3 forces back the piston 4 against the action of the spring 9, and, by this movement, a rotary valve 14 in the wide discharge pipe 15 leading from the injector to the float 2 is opened through the intermediary of the links 12, 13. When the supply cock is turned off, or the pressure in the supply cylinder falls, the reduction of pressure allows the valve 6 to open to the atmosphere, and the spring 9 forces the piston 4 forward, and the valve 14 is closed and retains the air in the float 2. Specifications 1713/12 and 1478/13, [both in Class 113 (ii), Ships &c., Kinds &c. of], are referred to.

According to the description, a combined truly-parallel movement may be obtained by making one or more of the links resilient, by connecting one or more of the links by resilient connections to the body and /or its support, or by making the support deformable. Various forms of links and resilient end connections therefor are shown. As shown in Fig. 7, each link is made in two telescoping parts, one part 7 being fixed to a cylinder 9 in which a piston 10 secured to the other part 8 is slidable against the action of springs 11, 11<1>, the outer ends of the links being ball-jointed to engage the engine 2 and support 1. In a modification, each link is rigid and is ball-jointed at one end to the body or support and at the other end to a spring-pressed piston slidable in the other member. Further constructions of links are shown in Figs. 13 and 14, in one case, Fig. 13, each ball-shaped end of the link 3 being mounted in a rubber bush 18 in a recess in a fixed member 19, while in the other case, Fig. 14, each end of the link is forked and carries a cross-pin 21a separated by an annular rubber bush 18a from a fixed annular member 21. Fig. 15 shows another construction of link in the form of a casing comprising a two-part annular member 3a having inturned portions separated by rubber blocks 18a from annular projections on the body and support. A substantially similar construction is also shown having in addition a rubbersheathed steel rod for limiting the relative movements.
