Title: Apparatus for silencing an engine
Inventor: TIMOTHY ROY JOHN NICHOLAS
IPC: F02B77/13
Filed: 1967-08-22
Abstract: 1,166,140. Sound insulation. VOKES Ltd. 5 June, 1968 [22 Aug., 1967], No. 38597/67. Heading F2X. [Also in Division F1] Apparatus for silencing an engine comprises an inner box for containing the engine resiliently mounted in an outer box, a pair of air inlet apertures formed through the walls of the boxes respectively and a pair of outlet apertures formed through the walls of the boxes respectively, the apertures of at least one pair being connected by a flexible sleeve, and inlet and outlet chambers mounted on the outside of the outer box over the inlet and outlet apertures thereof respectively, the walls of the boxes and chambers being rendered sound-absorbing. An I.C. engine 10 (or a gas turbine) and a generator 11 (or a compressor) driven by it are mounted within an inner box 13 on resilient mountings 14, the inner box being mounted within an outer box 15 on resilient mountings 16. An inlet chamber 23 and an outlet chamber 34 are mounted on the outside of the outer box 15. Air enters the inlet chamber 23 through an inlet 28, passes up on either side of a shelf 27 through filters and through a fan 24 driven by an electric motor 25, and thence through aligned inlet apertures 21, 20 in the walls of the outer and inner boxes respectively into the inner box 13, where it passes over the engine to assist in cooling it. Air leaving the inner box passes through the engine radiator 31 mounted in the outlet aperture 30 of the inner box and thence through an aligned aperture 32 of the outer box into the outlet chamber 34, leaving the outlet chamber via a slot-shaped outlet 35 and a passage 36. Exhaust gases pass through an expansion chamber 40 and a straight-through silencer 42 and thence via a metal bellows 44 into a pipe 45 in the outlet chamber 34. Flexible sleeves 22, 33 join the inlet apertures and the outlet apertures respectively, but the sleeve 22 may be omitted, the apertures 20, 21 then not being opposed to one another so that the space between the inner and outer boxes acts as a silencing chamber for air entering the inner box. The walls of the inner and outer boxes and of the inlet and outlet chambers and the passage 36 are all lined with sound absorbing material covered with cloth and expanded metal 50. The floor of the inner box is lined on the outside rather than on the inside so that oil from the engine is not absorbed by the lining. The fan 24 may be mounted within the inner box 13 and driven by the engine. The silencers 40, 42 may be located in the the outlet chamber 34, and the radiator 31 may be mounted in the aperture 32.

Title: Process for producing high-strength briquettes
IPC: C04B2/10
Filed: 1965-09-10
Abstract: Briquettes having a high green strength and a high strength after drying are produced from a finely divided natural or synthetic magnesium compound which yields magnesia, on firing, e.g. raw magnesite which has been freed from impurities by flotation by forming a solid, water-containing mixture of the magnesium compound and flue dust obtained by firing magnesite, subjecting the moist mixture to the action of gaseous carbon dioxide and thereafter pressing the mixture to form briquettes. The mixture preferably contains neutral or basic salts (e.g. MgSO4, preferably kieserite or epsomite) or solutions thereof in amounts such that the mixture contains 0.3-1.5 per cent by weight of these salts.  The neutral or basic salt solutions may be added to the mixture before and/or after treatment with CO2.  If MgSO4 solution is added it is preferably 29-32 DEG  Be-.  The carbon dioxide may be used in the form of exhaust gases which contain CO2. The "flue dust" (primarily caustic magnesia) is used in amounts of 5-30 per cent by weight based on the mixture of magnesia-yielding compound and flue dust.  The mixture is preferably pressed into briquettes 30-60 minutes after its preparation.

Title: Corpuscular beam in the atmosphere
IPC: B28D1/22
Filed: 1969-08-06
Abstract: 1284454 Electron-beam irradiation apparatus WESTINGHOUSE ELECTRIC CORP 6 Aug 1969 [30 Aug 1968] 39336/69 Heading HID Apparatus for cutting rocks &c. comprises means for generating a corpuscular beam, e.g. an electron beam, having a discharge outlet and means for ejecting a fluid or fluids in the direction of the beam at the outlet the beam-generating and fluid-supply means being in the form of concentric cylinders. A shown, an electron beam E passes into the atmosphere through a capillary nozzle 33 and impinges on a workpiece W. The nozzle 33 is surrounded by one or (as shown) two annular nozzles 45, 65. The inner nozzle 45 may be supplied with steam at a pressure between 0À2 and 10 atmospheres and the outer nozzle 65 with water at a pressure between 1 and 5 atmospheres. The ejected fluid produces a low pressure at the exit of the beam nozzle and creates a semi-vacuum in the drift tube 31. It also serves to wash away debris from the cutting face in the workpiece. Alternatively a combustible gas or liquid may be fed to the inner annular nozzle and oxygen to the outer nozzle, the heat generated by combustion serving to reduce the density of the gas outside the beam nozzle. The working fluid may be a plasma gas.

Title: Sulfhydryl resins
IPC: C08G65/326
Filed: 1965-09-17
Abstract: The invention comprises a sulphhydryl resin which is the reaction product of an inorganic hydrosulphide and a halohydrin ether of a polyol which is either a polyoxyalkylene glycol or an oxyalkylated alkane polyol.  The reaction may be effected under N2 or H2S, generally at a temperature between 25 DEG  and 100 DEG  C., specified inorganic hydrosulphides being NaSH, KSH, Ca(SH)2, Ba(SH)2, NH4SH and Sr(SH)2.  The halohydrin ether starting material may be obtained by reacting a polyhydric compound (see below) with an epihalohydrin, e.g. epichloro-, epibromo- or epiiodohydrin, 1,4 - dichloro - 2,3 - epoxybutane, suitably at 25-125 DEG  C. in the presence of a catalyst, e.g. Friedel-Crafts type catalysts, BF3 etherates and acidic and basic catalysts.  Suitable polyoxyalkylene glycols are those of the formula HO(RO)nH, where R is a C2- 6 alkylene radical and n is from 2 to about 40, and suitable oxyalkylated alkane polyols are those of the formula R11[O-(RO)mH]v, where R11 is a C3- 6 aliphatic hydrocarbon radical, v is 3-6 and m is 1 to 15, such compounds being the reaction products of an alkylene oxide and an alkane polyol.  The sulphhydryl resins may be used to cure epoxy resins, generally in the presence of a conventional curing catalyst. Suitable epoxy resins include (i) the reaction products of polyhydric phenols with polyfunctional halohydrins, e.g. the reaction product of bisphenol A and epichlorohydrin; (ii) the glycidyl esters of polymeric fatty acids; (iii) the polyglycidyl ethers of tetraphenols having two hydroxy aryl groups at each end of an aliphatic chain; (iv) epoxidized novolac resins, and (v) epoxidized olefins e.g. epoxidized polybutadiene, epoxidized cyclohexa-1,4-diene and the diglycidyl ethers of polyalkylene glycols.  In an example a sulphhydryl resin is used to cure the reaction product of bisphenol A and epichlorohydrin, which has an epoxy equivalent weight of about 190, in the presence of tri(dimethylaminomethyl) phenol as catalyst at 120-130 DEG  C.

Abstract: 1,191,067. Automatic position control. HERMANN BERSTORFF MASCHINENBAU G. m. b. H. Aug. 22, 1968 [April 4, 1968], No.40113/68. Heading G3R. Synthetic resin or rubber material is pressed against a rotating heating drum by an endless belt which also passes over a tensioning roller which is maintained in a desired attitude relative to the heating drum by a hydraulic actuator moving one end of the roller under the control of an electrical signal responsive to movement of that end. In Fig. 4, an endless belt 5, which presses a strip of synthetic resin or rubber against a drum (not shown) for heat treatment, is tensioned by a roller 7 the end bearings 10 and 11 of which are positioned along slides 12 by hydraulic rams 13 and 14. To prevent skew of the belt, roller 7 is maintained parallel to the heating drum by comparing the outputs of potentiometer pick-offs, such as 19, operated by movements of the two bearings, and applying any difference to control ram 14 in the appropriate sense to restore roller 7 to its proper position. Limit switches such as 22 reduce or increase hydraulic pressure if misalignment tends to be excessive.
