Title: Improvements relating to engine or other machinery lubricating systems
IPC: F16N39/06
Filed: 1944-11-07
Abstract: 583,595. Filters. SERCK RADIATORS, Ltd., UPTON, H. E., and ROBSON. F. Nov.7, 1944, Neo. 21863. [Class 46] [Also in Group XXXIV] A system for lubricating machinery includes one or more oil tanks, a pump, a filter, and a centrifuge arranged in a bye-pass between the filter and another part of the system, the filter being such that the oil bye-passed to the centrifuge serves to dislodge solid matter from the filter. The filter, as shown, comprises a cylindrical screen b secured to a cylindrical cage c within a hollow body a. The cage is connected to a spindle e which can be rotated by a handle f. The oil to be filtered enters through an opening h and most of it after being filtered passes through an outlet j. The remainder passes through part of the screen to a chamber m in which is arranged a scraper o. By turning the handle f different parts of the screen in turn are cleaned. The solid matter dislodged is carried way through an outlet n which leads to a centrifuge.

Abstract: 755,069. Continuous-discharge mixing- machines. FARBENFABRIKEN BAYER AKT.-GES. July 27, 1954 [July 27, 1953], No. 21963/54. Addition to 687,021. Class 86. Mixing and kneading machines described in the parent Specification are provided with cam plates which are of substantially equilateral triangle shape, each side of the triangle being an arc whose centre of curvature is the respective opposite corner of the plate. The cam plates 1, 1a, 1b, 1c and 2, 2a, 2b, 2c are arranged on shafts 4 and 5 respectively, the shafts being located in a casing 3 and spaced apart a distance approximately equal to the radius of said arc so that corresponding cam plates are almost in contact at their peripheries in any position to which the shafts may be rotated. Successive plates on each shaft are offset by about 30 degrees, the corners of the plates lying in helices so that rotation of the shafts in the same direction causes the material being mixed to advance through the casing. The three-sided shape of the cam plates provides that the volume of space containing the material being mixed remains constant during the rotation of the shafts, thus enabling the machine to be used for mixing dry and pulverulent material.

Abstract: 1472656 Hydrostatic transmission control SULZER BROS Ltd 17 May 1974 [17 May 1973] 22137/74 Heading F2W In a hydrostatic transmission having a variable displacement radial piston pump P supplying a fixed displacement motor M through a reversing valve 31, a throttle valve 51 in a return line 16 automatically throttles motor exhaust when the pump supply pressure 11 falls below a predetermined value in order to brake the motor M and thus prevent overrun and also to maintain a predetermined minimum pressure in the pump supply line 11. The throttle valve 51 is normally held in its lower position, as shown, by pump supply pressure 11 acting on the upper end of the valve spool against a bias provided by return line pressure 16 supplied to the lower end of the valve spool. The return line pressure 16 is maintained at a predetermined value by a make-up pump 15 and a relief valve 20. A control lever 21 acts through a cam mechanism 22, 25 and push rod on a control valve 4 of a follow-up servomotor 3 which adjusts pump displacement. The cam member 22 additionally operates a valve 40 controlling the exhaust of fluid pressure from the lower end 37 of the reversing valve 31. In the position shown the valve 40 is open to exhaust the chamber 37 whereupon a spring 36 holds the reversing valve spool 31 in its lower position for forward drive. Anti-clockwise movement of the lever 21 causes the cam element 22 to close the valve 40 whereupon pressure liquid, supplied from the return line 16 through a fixed orifice 38, builds up at the lower end 37 of the reversing valve spool 31 to move the latter up for reverse drive. A high pressure relief valve 35, filter 17 and cooler 18 are provided.

Title: Manufacture of aromatic sulphones and of tanning agents
IPC: C07C315/00
Filed: 1936-08-14
Abstract: Hydroxy sulphones are prepared by heating in a vacuum a sulphonic acid of an aromatic hydrocarbon or of a phenol or phenol ether and an unsulphonated phenol or an unsulphonated derivative thereof containing at least one free hydroxy group, e.g. a hydroxy sulphone. The products, which may be condensed with formaldehyde and an aromatic oxy compound to give tanning agents have wetting properties and may be used for combatting pests.  In examples: (1) phenol is sulphonated and heated in vacuo with phenol; water of reaction and also some phenol distils and dioxydiphenylsulphone crystallizes out; both the phenol which distils and the phenol sulphonic acid in solution may be used again; higher yields are obtained if a solvent, e.g. dichlorbenzene or a flux, e.g. a sulphonic acid of toluene, naphthalene or tetrahydronaphthalene, is employed; by adding cresol instead of phenol a mixed sulphone is obtained; (2) 4 : 4<1>-dioxy : 3 : 3<1>-dimethyldiphenylsulphone is obtained by using o-cresol and proceeding as in example (1); (3) m- or p-cresol is sulphonated with oleum and reacted with m- or p-cresol; (4) crude cresol D.A.B.4 is gradually added through a capillary tube to a sulphonated mixture prepared from crude cresol D.A.B.4; by determining the acidity or by observation of the water of reaction the desired proportion of cresolsulphonic acids and dioxyditolylsulphones is obtained; the product is diluted with water, allowed to stand overnight with formaldehyde and rendered weakly acid to congo by the addition of alkali lye; alternatively the product is rendered alkaline to phenolphthalein, the excess cresol removed by distillation and the residue reacted with formaldehyde; liquors directly suitable for tanning are thus prepared; (5) dicresylglycoletherdisulphonic acid is reacted with phenol, cresol or amylphenol; (6) dicresylglycolether is sulphonated and reacted with o-chlorphenol, 2 : 4dichlorphenol or dioxydiphenylsulphone; (7) dioxydiphenylsulphone is reacted with naphthalenesulphonic acid or tetrahydronaphthalenesulphonic acid in vacuo in the presence of sulphuric acid.  Specifications 375,160,416,191, and 425,527 are referred to.

A reduction of the pressure in the first compartment 137 causes the second diaphragm 104 to move valve 92 opening the passage thereby reducing pressure in the first compartment 135 and causing the first diaphragm 56 to move the actuating member 64 in a first direction. Similarly a lessening of the pressure reduction in the first compartment causes movement of the actuating member 64 in the opposite direction. A cable 82 causes partial opening of a throttle plate (18) when the induction system vacuum is excessive e. g. during deceleration. The device also functions as a dashpot device which slows the rate of closing of the throttle plate by restricting the flow of ambient air back into compartment 137 via restriction 124.

[Class 20 (ii)] Mine-props of the type in which an upper tapered member a is adapted to slide, with a yielding insertion and coacting wedge, in a tapered sleeve d supported at the upper end of the lower member b have the wedge formed composite with inclined surfaces extending in opposite directions. The wedge comprises a part f having inclined surfaces disposed at an angle and a double wedge g coacting with the wedge f and with the inclined surface of the sleeve d. An auxiliary wedge h, Fig. 3, or screw n, Fig. 4, maintains the wedges f, g in engaged position. To release the prop, the auxiliary wedge or screw is displaced, whereupon the pressure on the upper prop member causes the double wedge g to rise through a limited range and the upper prop member to fall, whereby it is relieved of its load and the composite wedge can then be lifted as a whole to allow full collapse. Stops k and p on the members of the composite wedge limit the movements of the main and auxiliary wedges f and h, respectively.
