Title: Improvements in rotary earth and rock drilling apparatus
IPC: E21B3/04
Filed: 1934-12-31
Abstract: 448,885. Boring earth and rock. DEMAG AKT.-GES., 64, Werthauserstrasse, Duisburg, Germany. Dec. 31, 1934, No. 37301. Convention date, Dec. 29, 1933. [Class 85] In a rotary earth-boring apparatus in which an automatic coupling is provided, the coupling has co-operating faces parallel with the axis of the coupling and the driven surfaces are capable of forward movement free of the driving surfaces so that, when a stuck drill suddenly breaks loose, overrunning can take place under the torsional energy of the drill stem. As shown, the rotary table b is driven by aligned shafts e, d connected by coupling members g, f, the member g being slidable and pressed by a spring &c. A cone &c. brake i may be provided, the brake being applied intermittently when overrunning takes place. The coupling may be arranged in the rotary table or in the drill stem at about the lower end of the supporting member.

Abstract: 341,653. Light-current relays. ELLIOTT BROS. (LONDON), Ltd., 1, Central Buildings, Westminster, and KIRBY, F. N., 8, Kinveachy Gardens, Charlton, London. Dec. 6, 1929, No. 37492. [Class 38 (v).] Relates to polarized telegraphic relays in which adjustment of the contact bias is effected by moving laterally a member carrying a pair of relatively fixed contacts between which a movable contact attached to the armature plays and consists in arranging the adjustment device including the manipulating knob on the top of the relay with no parts projecting out from the side of the relay casing so that when a group of relays are arranged in line no space between them to enable adjustments to be effected will be necessary. As shown in Fig. 1 the contacts and their adjusting device are carried by a base plate 1. Contact screws 2 are secured in holders 3 mounted on an arc-shaped base 4 slidable against the action of a spring 16 in a corresponding groove of the plate 1. The plate is moved for adjusting the contact bias of the relay by rotation of a knob 13 carrying a cam or snail 12 which bears on one arm of a pivoted bellcrank lever 11 the other arm of which bears on a projection 10 on the contact carrier 4. In the normal position a mark on the knob 13 is opposite an arrow on the fixed bar 8 but if the normal midposition of the movable relay contact 6 between the relatively fixed relay contact screws 2 is altered by adjustment of one or both of the latter the indicating position of the knob 13 may be correspondingly altered by adjustment of the eccentric projection 10 by the pin 10a so varying the point of engagement between the bell crank and contact carrier. Other correcting means may alternatively be employed such as the adjustment of the cam or snail 12 relatively to the knob 13 or the provision of an adjustable screw on the bell-crank 11 bearing on the cam 12.

A permanent magnet material which may be represented by the formula expressed in molecular percentages (1-0.01y) (85.7-x) Fe 2 O 3 , (1-0.01y) (14.3+2) BeO, y SiO 2 , where x is 0-4 is made by compressing at 0.5-20 tons/sq. cm. a mixture of particles of iron or barium oxides or compounds which convert to oxides and sintering it for about 10 minutes at 1150-1300‹ C. 83Fe 2 O 3 , 17BaO was made by ball milling Fe 2 O 3  and barium carbonate with water for 24 hours, drying, screening, compressing at 5 tons/sq. cm., sintering for 4 hours at 1280‹ C. and cooling for 15 hours. This material has high values and low temperature coefficients of B r , He and BH (max). Magnetically anisotropic material having improved magnetic properties in the direction in which the pressure is applied is obtained by presintering the material at 1200‹ C. for three hours in air, cooling for 12 hours and regrinding to particles of 1 micron size before compressing. Further improvement in He is obtained by adding 0.1-6% preferably 1-2% of silica or a material which converts to silica on heating, during either of the grinding steps. Examples are described of the production of materials having the formulµ 81.5 Fe 2 O 3 , 16.7 BaO, 1.8 SiO 2  and 82.6 Fe 2 O 3 , 16.9 BaO, 0.5 SiO 2 . A machinable material is produced by sintering the material of the first in the above processes before the compression step at 1250‹ C. for four hours, cooling it in 15 hours, regrinding and mixing with it a binder such as a condensation polymer in a solvent which slowly evaporates, compressing at below 0.5 20 tons/sq. cm. and heating e.g. at 180‹ C. to eliminate the solvent and harden the binder. Suitable binders are epichlorhydrine, diphenolpropane or epoxy or silicone varnishes.

Supporting rings 21 within each panel 20 enable a welded connection between stub outlets 13 and respective panels 20 to be achieved in a single step by a pressure welding process. In another embodiment a connector element for connecting a single radiator panel to a feed or return pipe has a spherical body formed by welding together two dissimilar shells and is provided with a pipe coupling socket and a single stub outlet for welding to the radiator panel, the connector having a flattened portion diametrically opposite the stub outlet to reduce the size of the connector and hence reducing the space required between the panel and an adjacent wall. In yet other embodiments the stub outlet or outlets may be inwardly extending to provide a connector having a smaller overall diameter. The connector elements may be made by a method comprising the steps of forming a circular sheet metal blank; deep drawing the blank to form a cup shape; swaging the rims of the cup inwardly to produce a spherical shape with a circular opening therein; cutting a further circular opening in the spherical body and welding one end of a pipe coupling socket to the further opening. A connector having two diametrically opposed circular openings therein is formed from a tubular blank by swaging the end portions of the blank inwardly to form a spherical body with two holes diametrically opposed; cutting a third circular hole in the body and welding a pipe socket to the rim of the third hole. The connector element shown in Fig. 6 may be made from two circular blanks each of which has a central circular hole therethrough by forming the blanks into hemispheres each having a stub outlet by a deep drawing process and then welding the rims, which may be chamfered, of the two hemispheres together to form a spherical body with two stub outlets and finally cutting a circular opening in the spherical body and welding e.g. by an electrical resistance welding method a pipe socket to the rim of the opening.

The textile materials which may be of natural or regenerated cellulose or silk, are dyed by treatment with an aqueous solution of the water-soluble dyestuff followed by treatment with an alkali, preferably at elevated temperature, to give violet, grey to greenish-blue shades.  Examples are given. Cotton fabric is printed with an aqueous paste containing the water-soluble dyestuff, a thickener and sodium acetate and then steamed to give a violet-black shade.

A photo-resistor Rph exposed to ambient illumination forms with resistor R v , adjusted to take account of photographic parameters and  resistors R1, R2 a bridge circuit. The output of bridge balance detecting transistors T 1 , T 2  is connected via transistors T 4 , T 5  and T 7 , T 8  to transistors T 6 , T 9  respectively. Circuit components D 1 , R 8 , R 9  are chosen so that the voltage at the base of transistor T6 is slightly higher than the threshold voltage between the base and emitter of transistor T 6  when the source E is at the minimum usable voltage level. If the voltage of source E falls below this level, transistor T 6  is permanently cut-off so that light emitting diode D 3  is never illuminated. Diode D4 is connected in a similar circuit. During normal operation, one of the diodes emits to indicate an under exposure, the other diode emits to indicate an over exposure, whilst both diodes emit to indicate a correct exposure. If no diodes emit, this indicates that the source E has fallen below the predetermined minimum level. In another embodiment, Fig. 2 (not shown) transistors T 5 , T 6  and T 8 , T 9  are serially connected instead of parallel connection of the embodiment shown. In a further embodiment, only one diode is used which can only emit to indicate a correct exposure and an adequate source potential. Incandescent lamps may replace the light emitting diodes.
