Abstract: 460,686. Sharpening razors &c. WILKINSON SWORD CO., LTD., and RANDOLPH, H. B. April 6, 1936, No. 10071. [Class 60] [Also in Group XIV] A device for sharpening safety razor blades &c. comprises a casing a with a lid b, wherein the razor frame d is held with the blade 2 in the position shown, and lying between two pads 9, 10 of sponge rubber &c. carrying leather &c. stropping surfaces 11 and supported by frames 7, 8 pivoted on a spindle 12, which is slidable in slots in the casing a. The frames 7, 8 have inclined slots 15, 16 in their sides engaged by pins 26 in T-shaped ends of a slide 13 slotted to pass over the spindle 12 and having, outside the casing, an operating-knob 18 ; springs on the spindle 12, between the frames 7, 8 and the walls of the casing, retard sliding motion of the frames. In operation, when the slide 13 is moved to the left, the pins 26 cause the frames 7, 8 to open about the spindle 12, so that, when the frames are moved by further movement of the slide, the surfaces 11 are clear of the blade. Upon reverse movement of the slide, the frames first close down to press the surfaces 11 on to the blade, and then are moved across the blade edge. The razor frame shown comprises a spring part 4 with serrated bushes at its ends engaging correspondingly shaped surfaces on the blade clamp 3, so as to hold the blade in any desired position.
Patent GB-1514634-A (GB)
Title: Roller mounting arrangement in a web processing machine and a bearing block therefor
IPC: B65H23/04
Filed: 1976-03-12
Abstract: The tension of the paper web (1) can be varied by adjusting a braking roller (30). Furthermore, the tension can be displayed (27) or recorded (28). Variations in tension in the paper web (1) are determined by means of strain gauges, which are mounted in the base region of bearing supports (3, 4). Two strain gauges are present for each bearing support, and are mounted on axially parallel surfaces of the bearing support one behind another in the direction of the paper web, the expression axially parallel applying with reference to a web-deflecting roller (2). The paper web (1) presses onto this roller (2). So that the force exerted by the web on the roller (2) is not vertical but extends at an inclination to the vertical, the inlet angle of the web (1) relative to the roller (2) is selected to differ from the outlet angle. In order to achieve a high sensitivity to the extension of the bearing supports (3, 4), the vertical member of the bearing supports is dimensioned in an appropriately yielding fashion. Plug and socket connections (24) to the strain gauges lead to a measuring device (26) by means of which a controller (29) for adjusting the braking roller (30) can be influenced. A desired tension of the paper web can be held constant by control. <IMAGE>

IPC: C07C11/02
Filed: 1960-03-23
Abstract: <FORM:0893504/IV (b)/1> In the production of unsaturated hydrocarbons, e.g. ethylene or acetylene by cracking liquid or gaseous hydrocarbons in the gaseous phase with oxygen in a flame, carbon black produced is removed from the product by washing with a liquid hydrocarbon and the suspension is burned in the cracking chamber with an amount of oxygen capable of converting 1/3rd to 1/50th of the liquid hydrocarbon-carbon black mixture to carbon dioxide and water.  In the drawing hydrocarbon enters the cracking chamber 1 by line 3 and oxygen by line 2.  A liquid hydrocarbon quench is sprayed into the products at 4 and the products washed in scrubber 8 with liquid hydrocarbon.  Liquid hydrocarbon containing carbon black collects in the sump of the scrubber and is cooled and recycled to the quench and the top of the scrubber, part being led off to the atomiser 12 with oxygen from line 2, a corresponding amount of fresh hydrocarbon being introduced from source 16.

Abstract: 147,996. Odell, H. April 24, 1919. Braking.-The steering or other wheels of a two or four-wheeled vehicle are mounted on stub axles which can be deflected to make the wheels .converge to produce a braking effect. For this purpose the stub axles are provided with arms connected by a crossed link, or the connecting-link may be variable in length. In the form shown in Fig. 2, non-steering wheels are mounted on stub axles T having oppositely-directed arms L connected by a cross link 3. Normally, the axles T are in the same vertical plane and are deflected as shown by a brake lever connected by a link 4 with an extension L<2> of one of the arm L. The link 3 may be in two independent parts connected to a separate operating-lever. In the form shown in Fig. 13 as applied to steering-wheels, the connexion between the arms L is in the form of a right and left handed screwed rod engaging internally screwed sockets pivoted to the arms L; the rod can be rotated to lengthen or shorten the connexion by means of a worm wheel thereon engaging a hand-operated worm. The rod &c. is enclosed in a casing supported by loosely pivoted members L<4>, one of which is provided with an extension L<5> which is operated for steering. In the form shown in Fig. 11, the members L are connected with telescoping members 33 fitting into the hollow steering connexion 3. The members 33 are connected by links 22 to a three-armed lever L<3> in the operation of which the members are moved outwards from the member 3.

Title: Method of firing, roasting and sintering cement, lime or similar material
IPC: C04B7/40
Filed: 1931-04-09
Abstract: <PICT:0386330/III/1> Cement raw material, lime, &c. in the form of granules, is, prior to calcination on a travelling grid or the like as in the parent Specification, dried under such conditions that the material is not exposed to a calcining temperature during the drying treatment and breaking up or bursting of the granules is prevented. The drying may be effected by forcing through the material a mixture of exhaust gases from the rotary furnace mixed with cold air or with waste gases from the travelling grid.  This may be effected by providing a separating wall between the charging hopper and the calcining chamber, projecting downwards and leaving a space at the bottom for the entry of a limited quantity of drying gases.  A slide or the like may be provided to adjust the opening, and the suction draught may be regulated by providing below the drying chamber a protection sheet and flap valve.  In a modification, the drying chamber is cut off from the calcining chamber.  As shown, the granulated material from the hopper 3 is fed on to a travelling grid 1 on which it is first dried and then calcined.  The drying chamber 7 is separated from the calcining chamber 9 by a wall 8 extending downwards, leaving a space at the bottom for the passage of gases. To control the suction draught a protecting sheet 10 and throttle flap 11 is provided beneath the drying chamber.
