Title: Method of and apparatus for surfacing refractory slabs or the like
IPC: B28B11/08
Filed: 1967-01-12
Abstract: 1,119,905. Grinding. SUPER-CUT Inc. 12 Jan., 1967 [17 Jan., 1966], No. 1786/67. Heading B3D. A method of reducing an undulatory surface area on a refractory slab or the like to a substantially smooth planar condition, the area having relatively high and relatively low surface regions, comprises sawing a series of closely spaced parallel narrow linearly straight kerfs through the high surface regions to establish intervening ribs, fracturing the ribs adjacent their base regions and forcibly ejecting them from the surface area, and finally reducing substantially all trace of the remaining rib structure to planar configuration by abrading them from the surface area. In apparatus for carrying out the method, a block 10 which is to have both its opposite surfaces reduced simultaneously is secured by wedges 26 in a rectangular frame 16 having shoes 36 engaging rails 32, 37 along which the frame is moved by engagement of lugs 42 on a chain 40 with the lower shoes. The slab extends on both sides of the frame and passes between two pairs of sawing tools 60 rotated from a common drive 20. Each tool consists of a plurality of discs 62 having abrasive segments secured to the periphery of metal discs and the discs of the tools on each side are staggered relative to each other so that the second tools in the direction of feed of the slab cuts kerfs 'between those of the first tools. After passing between the sawing discs, the slab is carried between a pair of tools 80 each of which consists of a disc 88 having abrasive segments 92, 94, 96, Fig. 7. As the slab passes through the discs, the segments 96 fracture and break away the ribs formed by the sawing discs, the segments 94 further reduce the ribs by impact and abrasion, and the segments 92 grind planar surfaces on the slab.

Title: Optical observation and/or photographically recording instrument
IPC: G02B21/06
Filed: 1955-01-21
Abstract: 764,934. Optical apparatus. ZEISSSTIFTUNG, C., [trading as ZEISS, C. [Firm of]]. Jan. 21, 1955 [March 16, 1954], No. 1845/55. Class 97(1) A light source in an optical instrument is arranged for viewing a reflecting and transmitting object by reflection, and the light which passes through the object and is reflected back into the instrument by a reflex reflector placed behind the object. Thus, in a microscope, when the mounting carrying the objective, the light directing means and the object are tilted, it is unnecessary to tilt the reflector. The magnitude of the surface area of the reflector may be such that it is unnecessary to displace it laterally when tilting the instrument through a large angle. The bead type of reflex reflector may be used when only a partial return of the incident light is acceptable. An even reflection is stated to be obtained from the triple mirror type of reflector by slightly matting the upper surface of the reflector.
Patent GB-472250-A (GB)
Title: Improvements relating to electro-magnetically operated mercury switches
IPC: H01H29/18
Filed: 1936-01-20
Abstract: 472,250. Electromagnetic interrupters. CIANCHI, A. Jan. 20, 1936, No. 1849. [Class 38 (v)] An electromagnetic interrupter of the type comprising a vessel containing a magnetic plunger the extent of immersion of which in mercury or other conducting liquid being varied electromagnetically and the consequent displacement of the surface of the mercury causing it to make or break connection with one or more contacts has such contacts contained in a branch of the vessel into which the conducting liquid flows to make contact when the plunger moves down and out of which it flows to break contact when the plunger moves up, the switch formed by the contact or contacts in the branch and the liquid being connected to the electromagnetic means for moving the armature so that the switch is caused automatically to make and break contact repeatedly and the vessel is mounted so as to be capable of being tilted to vary the frequency at which contact is made and broken. As shown in the Figure, the main interrupter comprises a receptacle 3 containing mercury which normally touches a contact 6 but does not reach contacts 9, 10 in a side-passage 8. When the cylindrical armature is drawn down however by energization of the coil 11 surrounding the container the level of the mercury rises to the contacts 9, 10 but contact is not immediately established between them and the contact 6 as a ball valve 13 is forced against a seating consisting of an insulating liner 12 so that mercury in the armature is temporarily drawn down from the contact 6. Mercury, however, leaks past the valve through a restricted passage 14 so that after a slight delay contact is established through the mercury and the operating coil is short-circuited. The armature is then free to rise, its upward movement being unimpeded as the ball 13 is then forced off its seating. In the arrangement shown a circuit from the self-interrupting switch 3 at contact 10 controls a second mercury interrupter in a vessel 3<1> which in turn controls the load circuit. Both of these interrupters are carried on angularly adjustable bases so that the time taken for the mercury to reach contact 9 may be lengthened or decreased and the frequency of interruption can consequently be varied. In a modified arrangement the tilting of the base is effected through eccentric mechanism. Specification 453,229 is referred to.
