Title: Improvements in mining machines of the kind adapted to travel along the floor of a mine
IPC: E21C35/00
Filed: 1947-08-08
Abstract: 655,717. Spring drums. JOY MANUFACTURING CO. Aug. 8, 1947, No. 22716/49. Convention date, Feb. 13, 1941. Divided out of 655,670, [Group XXI]. [Class 78 (ii)] [Also in Group XXI] In a mining machine which traverses the floor of a mine, a capstan is provided on the chassis of the machine which automatically winds in the cables supplying power to the machine when the chassis retires and freely pays out the cables during the advance of the machine. The front wheels of the machine are driven by hydraulic motors 105 to which power may be supplied from a high capacity pump 217 through a manually operated four-way valve 221, the setting of which determines whether the liquid flows through pipe 225 or pipe 226 and in consequence in which direction the motors 105 rotate. In addition, power may be supplied from a low capacity pump to either of pipes 225, 226 depending on the position of a valve in the multiple valve chest 10. Depending on the direction of flow to the motors 105 so liquid may be admitted to the motor 195 of the capstan, the byepass 306 being so designed that when the machine is advancing the capstan free wheels and unwinds cable, but on the rearward movement of the machine the byepass 306 diverts the liquid flowing from the motors 105 to the sump 215 through the capstan motor 195. For the motor 195 to run, liquid enters from pipe 304, through chamber 322 and passages 304, 316 and 320 to motor 195 and back through passages 321, 319, 325 past valve 327 and away through pipe 305. If liquid enters from pipe 305 the hollow valve 327 is forced over to the position shown in Fig. 20, flow being through passage 332, chamber 308, past valve 326 and through pipe 304, the valve thus closing the passage to the capstan motor.

Hair-curling appliances. - Apparatus for permanent hair-waving comprises a steam generator a, Fig. 1, supported by an arm b of a stand, and provided with a series of outlet pipes a<1> adapted to receive rubber connecting tubes c. The generator is provided with a false bottom beneath which an electric heating element a<2> is fitted. A safety-valve a<3>, a filling connection a<4>, and a blow-off cock a<5> are provided. A guard-ring d prevents the tubes c from touching the generator. Each tube c is connected to a hair-waving device, preferably through a T.piece c<1>, one branch of the latter having a valve c<2> and leading to another tube c<3>, and the other branch being provided with a bulb c<4> acting as a trap for condensed steam. Alternatively, a single conduit may lead from the generator to a manifold pipe from which separate tubes may be taken to each waver. A suspending device such as a spring- controlled steel tape, wire, or chain may be clamped to the guard-rail d so as to hold the tubes c<3> in the desired positions. The tubes c<3> may be each connected to a hair-waving device of known pattern in which steam is introduced into a jacket surrounding the hair. Or a double-walled jacket may be used, the inner wall having perforations through which the steam penetrates to act upon the hair wound upon a curler and inserted in the central space. Alternatively, the hair may be wound on a curler comprising an inner tubular member e, Fig. 4, to one end of which a steam tube c<3> is fitted. The tube e is bell-mouthed at the inner end, and at the other end is fitted a milled flange or ring e<2>. Upon the tube s an outer tube f, upon which the hair is wound, is mounted so as to be rotatable thereon, locking means being provided, and the end e<1> of the tube may have a slot or other means to facilitate the attachment of the hair thereto. After the hair has been wound on the curler, it is enclosed in a jacket of rubber or other material, and the steam supplied through the pipe c<3> escapes from the end e<1>, passing over the coiled hair within the jacket. In a modification of the curler, the inner tube is closed at the end by a forked member e<1>, and has perforations near that end, and the outer tube f is also perforated over a part or the whole of its length, so that the steam percolates through the hair. This type of curler may be used with a double-walled jacket so that heat may be applied externally of the hair at the same time. Borax or other preparations may be introduced into a jacket adjacent the hair, and any appropriate oil or other volatile substance may be introduced into the steam generator. The hair may be damped, or surrounded by a sachet containing borax or other preparation, and the steam supplied internally and conveyed away without coming into contact with the hair.

Title: Improvements in machines for moulding briquettes
IPC: B30B11/00
Filed: 1933-08-15
Abstract: 406,585. Moulding briquettes. BOWLING, R. T., 1015, 3rd Street, Lewiston, Idaho, U.S.A. Aug. 15, 1933, No. 22796. [Class 87 (ii).] Presses for moulding briquettes from sawdust, wood shavings &c. comprise a hopper 2 into which the material is placed and from which it is fed by a tapered feed screw 7 working within a conical chamber 1 having a cylindrical extension 3. A member 13 is rigidly mounted in the end of the feed screw and carries a head 12, slotted at 14, and formed with a radial cutting edge 15 on one face and with a cam surface 16 on its other face. Material passing along the feed screw is compressed between the end of the screw and the head 15, rotation of the material at this stage being prevented by ribs 11. The cutter 15, rotating with the feed screw cuts off a ribbon-like strip from the compressed material, which passes through the slot 14 and into the chamber 3 in helical form. The cam face 16 on the head 12 compacts the helices into close formation. A rotary carrier 4, Fig. 5, is provided with water-cooled moulds 5 round its outer edge and is intermittently rotated by pawls 30 and fluid pressure mechanism 35 to align the moulds successively with the chamber 3. A plunger 6 which reciprocates along the axis of the chamber 3 and of its aligned mould 5 presses against the end of the briquette B (which is within the mould and which was formed at the previous alignment of the mould with the chamber),with a predetermined fluid pressure, the material in the chamber being fed forward by the screw 7 against this pressure to eject the briquette B and to recharge the mould. On rotation of the mould carrier the stream of material is severed, the mould passing between end plates 44 which maintain the material in compressed condition within the mould. The plates 44 enclose only a portion of the mould carrier face, and when the charged moulds emerge from the plates 44, any projecting material is trimmed off the briquette by fixed cutters 48. The plunger 6 is returned by rack-and-pinion gear driven by power. The moulds are cooled by water circulated through the tubular shaft of the mould carrier and through radial pipes 46, 46<a>.

Abstract: 177,130. Automatic Telephone Manufacturing Co., Ltd., (Assignees of Martin, T. G.). March 15, 1921, [Convention date]. Automatic exchange systems.-Substation apparatus adapted for central battery working is so arranged that, when the finger-dial is in an offnormal position, the shunt springs of the subscriber's impulse-sender short-circuit both the transmitter and receiver, and connect in shunt with the impulse springs a circuit containing capacity. Fig. 1 shows the application to a desk set in which the usual combination of transmitter T, receiver R and impulse-sender S is connected with the bell box containing also the condenser C and induction coils 4, 5, by a threeconductor cord. Movement of the impulse sender S from its normal position connects all the shunt springs 12, 13, 14 together. In this position and whilst the impulses are being transmitted, the transmitter T and receiver R are short-circuited, the bell M is shunted by a lowimpedance circuit containing only the two induction coils 4, 5 in series, and the impulsesprings 15, 16 are shunted by a circuit containing the condense: C and the shunted bell. The Specification as open to inspection under Sect. 91 (3) (a) refers also to an alternative arrangement in which the impulse-springs may be included in the bell circuit, the cord from the bell box in this case containing four conductors. This subject-matter does not appear in the Specification as accepted.

Abstract: 535,413. Television ; valve amplifying circuits. HAZELTINE CORPORATION. Aug. 8, 1939, No. 22870. Convention date, Aug. 31, 1938. [Classes 40 (iii) and 40 (v)] A television video-frequency amplifier with amplitude discrimination for increasing contrast &c. comprises two valves, one repeating the whole of the amplitude range and the other a selected part of the amplitude range, the outputs being combined to develop a composite signal of the required contrast &c. In Fig. 1, the control circuit of valve 21 is connected across the cathode resistance 22 of valve 20, resistance 22 and bias potential 23 being adjustable. Valve 20 repeats the whole amplitude range but potential 23 is adjusted so that only signals above a certain amplitude are repeated by valve 21. Adjustment of resistance 22 controls the negative feed back and also the amplitude of the signal applied to valve 21, these effects opposing each other. In Fig. 3, the signal is applied to the grids of both valves 20a, 21a, an additional opposed battery 27 in the circuit of valve 20a causing this valve to saturate for signals above a certain value. The adjusting-devices of batteries 27, 23a are ganged as shown at U. The composite characteristic of valves 20a, 21a may be such as to increase the amplification of the black or white parts of the picture, or of both black and white relative to the grey parts, while the overall amplitude range remains substantially constant for all adjustments.

Abstract: 740,729. Grinding machines. NEWALL ENGINEERING CO., Ltd., and HOARE, S. W. Sept. 11, 1953 [Sept. 12, 1952], No. 22989/52. Class 60 [Also in Group XXIX] A lapping or grinding machine comprises a base 11, Fig. 1, an overframe 18 having two upstanding limbs 19 and a bridge portion 20, lower and upper laps 34, 35 having horizontal lapping or grinding surfaces, driving means for relatively rotating the upper and lower laps toward and away from each other. The lower lap spindle is driven by a two-speed electric motor through a worm and gear wheel enclosed in an oil bath and drives through toothed gearing a shaft passing through an axial bore in the spindle. This shaft is connected by adjustable planetary gearing with three pins 36 which, when flat work is to be lapped, serve to impart an orbital motion to a work holder consisting of a disc of wood or metal having a series of cut outs to receive the workpieces. For cylindrical lapping the workholder is held in an offset position with respect to the laps by a guide bar. The spindle 27, Fig. 4, of the upper lap is mounted in a quill 29 and rotated in the opposite direction to the lower lap by a gear 24, a worm wheel 29 and a single speed electric motor. The quill is connected by a yoke 48, Fig. 3, to two hydraulic cylinders 46 which are connected in a hydraulic circuit (see Group XXIX) to support the weight of the lap and to enable the quill 29 to be moved axially in the bridge portion 20 at various rates under the control of a valve. A stop device consisting of a screw-adjusted lever 74, Fig. 4, adjustably clamped in guides 73 on the bridge portion 20 engages a shoulder 77 on the quill 29 to limit the downward movement of the upper lap and operates a visual dial indicator 81. The device may also incorporate a warning lamp to light up just before the dead stop position is reached. Lapping fluid, such as paraffin, is fed to the laps through a hose 41, an annular duct 43 and apertures 44, the used fluid draining to a sump in the base 11. A vertically movable counterbalanced splash guard 100 surrounds the laps and provision is made for stepwise rotation of the lower lap to facilitate loading and unloading of the workpieces. Holes 103 receive bars for lifting slings. Trueing. Two diamonds, one for the upper lap and one for the lower, are. adjustably mounted on heads 86, Fig. 8, on the end of a carrier bar 85 connected to a piston 90 slidable in a cylinder 89 and a guide bar 87 slidable in guides 88. The supply of fluid to the cylinder 89 is controlled by a valve which permits various rates of traverse for the diamonds. The upper lap is dressed first and is then brought as near parallel to the lower lap as possible by adjusting the over-frame 18 by means of, three adjusting bolts 96, two of which are arranged at the back and front respectively' of one limb 19 while the other is positioned midway along the side of the other limb. After this adjustment, the lower lap is dressed and the over-frame secured by two bolts 97 positioned on opposite sides of the same limb 19.

Abstract: 334,032. Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij, (formerly De Bataafsche Petroleum Maatschappij). Oct. 23, 1928, [Convention date.]. Pitch and tar are treated with gases by a continuous process in order to obtain products for roofing and insulating. Gases used include air or oxygen, ozone, nitric peroxide, sulphur dioxide, chlorine, or mixtures of air or oxygen with the other gases. The process is described in connection with blowing asphalt. Molten asphalt is forced from a reservoir 2 by pumps 1 through line 3, coils 5 in tube furnace 4, and into the separator 7. Air is passed through a meter 10 and line 11 with connections 12 - - 15 to the feed line 3 and/or the coils 5. The air line 11 leads to a perforated pipe 16 in the bottom of the separator. The ashphalt is heated to 340‹ C. in the coils (or, according to the Specification as open to inspection under Sect. 91 (3) (a), to 250‹ C.). Air and gaseous products leave the separator at 18, and yield a certain quantity of liquid fuel and combustible gas. Asphalt is returned from the separator to the feed line through pipe 8 by pump 9. When a sample taken at 20 has the desired properties, blown asphalt is drawn off continuously at 19 and a fresh supply is admitted continuously to the feed line 3.
