IPC: E21B47/16
Filed: 1917-02-17
Abstract: 104,341. Kaempfe, H. Anschutz-. Feb. 19, 1916, [Convention date]. Addition to 100,130, [Class 85, Mining &c.]. Producing intermittent or repeated audible signals.-Deviation of a bore-hole from the vertical is indicated by acoustic signals. Upon the apparatus, which is contained within the bit-holder, becoming inclined to the vertical so as to produce relative movement between a pendulum 31 and a contact within the apparatus, an electric circuit is completed and the signalling-hammer operated by pins 13 on a worm-wheel 11 driven by an electro-motor set in operation upon completion of the circuit. The contact 21 co-operating with a contact on the pendulum is moved away from the pendulum by means of the threaded shaft 18, which is rotated by gearing from the shaft of the wheel 11 and traverses a half-nut 19" on the slide carrying the contact 21. The number of blows of the hammer heard' thus furnishes an indication of the amount of the deviation. The circuit of the motor is kept open and the threaded shaft 18 maintained out of engagement with the nut 19<11> while the drill is in action, by means of an inertia plunger 25 which is carried down by its momentum when a blow occurs and can only move upwards slowly as air enters the exhausted space 25<1> through a fine bore. The invention is also stated to be applicable to measuring-apparatus such as is described in Specification 27005/12, [Class 97 (ii), Surveying &c. instruments.].

Title: Improvements in or relating to prepayment mechanism for electricity meters and the like
Filed: 1939-01-24
Abstract: 524,219. Prepayment mechanism for meters. SWITCHGEAR & METERS, Ltd., and ANGOLD, A. W. Jan. 24, 1939, No. 2462. [Class 27] Returning coin.-In mechanism for electricity meters and the like, the conduit between the coin pocket and the coin box is provided with a coin-diverting device which, although normally allowing coins to pass through the conduit to the coin box, is adapted to be operated to divert unsuitable coins from the conduit to an outlet slot, operation of this device also effecting temporary locking of the prepayment mechanism against crediting movement. The coin pocket or conduit 6 leads to a hollow block 3 having a flap 4 pivoted at 5 and connected by a spring 7 to a lever 8 pivoted at 9. The lever is normally held in the position shown in Fig. 1 by a spring 16, Fig. 2, but when a vertically-sliding button 13 is depressed the lower end 11 thereof acts on a pin 10 on the lever and rocks the latter to the position shown in Fig. 2. A coin inserted in the pocket normally rests on a platform 21 pivoted at 22 and having a projection 20 held by a rocking catch 26. In this position the coin is gauged by means of a caliper jaw 25 as described for example in Specification 515,223. If the coin is unsuitable the coin may be returned by depressing the button 13 thus rocking the lever 8. The initial movement of the lever causes the spring 7 to move the flap 4 from the position shown in Fig. 1 to that shown in Fig. 2; further movement causes (1) one end of the lever to rock the catch 26 thereby freeing the platform 21, and (2) a pin 17 on the lever to engage an extension 24 of the platform and thereby tilt the platform to allow the coin to fall through the block 3 and be diverted by the flap 4 to the outlet. Further, as the lever 8 is rocked a curved tooth 27 thereon engages a notch 28 in a selector wheel 29 and locks the same so that the crediting mechanism, which has been released by a catch 30, cannot be rotated.

Title: Improvements in or relating to the manufacture of artificial threads
IPC: D01D5/20
Filed: 1949-02-01
Abstract: Artificial filaments having aperiodical variations in denier along their length are obtained by causing impulsive variations in the rate of supply of spinning liquid to the nozzles and by leading the filaments, after their formation in a coagulating bath or gaseous setting <PICT:0659421/IV (a)/1> <PICT:0659421/IV (a)/2> <PICT:0659421/IV (a)/3> <PICT:0659421/IV (a)/4> medium, into contact with an eccentric thread guiding disc, which is freely movable on a horizontal or almost horizontal axis of rotation, and thence to a positively driven pulling-off device, the filaments running over only a part of the periphery of the eccentric disc and the disc being set in motion by the filaments alternately by adhesion and by sliding friction.  The aperiodic variations in the denier render the filaments suitable for the manufacture of fabric resembling shantung fabric.  The spinning liquid may be supplied to the nozzle by a pump with irregular delivery.  The pump may be provided with a constant drive and an auxiliary drive which imparts to the pump shaft a rotational velocity which is a multiple of its normal velocity a few times and for a short period during each revolution, e.g. the momentary velocity may be three or four times the normal velocity of revolution.  As shown in Fig. 1, the spinning pump 1, operating impulsively, forces the spinning solution through filter 2, and nozzle 4 to form filaments 5 which pass through the coagulating bath 6 and then past the freely rotatable guide-disc 8 which is eccentrically supported on shaft 7.  The filaments may be passed to stretching devices, deacidifying baths, and other treatment baths, and may then be wound up.  The disc may be solid, or it may have part of its interior cut out.  If its weight is too low, it may be provided with an extra weight.  The edge of the disc may be grooved. The irregularities in denier caused by contact of the filaments with the disc are enhanced by the irregularities in denier and state of coagulation or setting of the filaments due to the irregular extrusion.  The process may be used in dry or wet spinning processes. As shown in Fig. 4, the spinning pump 1 has a shaft 13 to which a ratchet wheel 14 is fixed.  Rotating on bolt 16 is a gear-wheel 17 and ring 18.  Pawls 20 (Fig. 6), transmit the movement of gear-wheel 17 via ratchet wheel 14 to the pump shaft 13.  Gear-wheel 17 is driven by pinion 21.  Disc 22 with ring 23 also rotates on the ratchet wheel 14.  Pawls 25 (Fig. 7), transmit the movement of disc 22, which is normally held stationary by means of a spiral spring. Cam disc 31 has three cams 32 which give, three times per revolution of disc 31, a temporary movement to disc 22 and the pump shaft is momentarily rotated faster than its normal speed.  During this temporary movement the ratchet wheel 14 rotates underneath pawls 20 of gear-wheel 17 which continues rotating with constant angular velocity.  Specification 516,458 is referred to.

Title: Improvements relating to cathode ray tubes
IPC: H04N9/26
Filed: 1953-02-04
Abstract: 726,214. Colour television tubes. GENERAL ELECTRIC CO. Feb. 4, 1953 [Feb. 5, 1952], No. 3192/53. Class 39 (1). In a colour television tube in which an electron beam projected on to the back of an apertured electrode 21 at an average angle of incidence of 45 degrees, passes through the apertures 22 and is reflected by an optically transparent electrode 26 to fall on the phosphor colour pattern 23, 24, 25 carried on the front surface of the apertured electrode, the apertures and the phosphor colours between the apertures are arranged in concentric arcuate rows as shown in Fig. 5. The angle of incidence of the electron beam is constant along an individual row of apertures, and the spacing between the rows of apertures is so varied that the same difference of voltage between the two electrodes will cause the same colour to be excited for any point of the target area. The phosphors occupy an area of the order of three-quarters of the target area and the apertures occupy approximately one half of the remaining area. The apertures in the apertured electrode are formed oblique to the plane of the electrode to conform with the angle of incidence of the electron beam. The apertured electrode consists of a copperberyllium-chromium or cobalt alloy, and the apertures are formed by a photomechanical process involving etching from slightly displaced points on opposite sides of the electrode. Each colour phosphor is laid down on the apertured electrode by first printing by letterpress or lithographing a vehicle such as nitrocellulose or linseed oil along the desired lines, and then applying the phosphor in powdered form. The electrodes 21, 26, are spaced apart by glass insulating blocks 44, Fig. 1, which have conducting layers of very high resistance formed on their surfaces. Potential gradients are thus set up to reduce the possibility of arcing between the electrodes 21, 26. The electrode structure is held together by means of clamps 43. The electrode 21 is bolted to a supporting frame 41. Adjustable screws 45 on one limb of the clamps 43 press the electrode structure with interposed spacing blocks 44 against ball bearings set in the other limb of the clamps. In order to prevent vibration of the relatively thin electrode 21 thin flat strips held in blocks 61 secured to the electrode supporting frame 41 bear against the electrode 21. These strips are edge on to the electron beam. The frame 41 is provided with extensions which are bolted to conductive supports 67 bearing against and bolted to the metal body portion 11 of the envelope. Specifications 531,586, [Group II], and 713,875 are referred to.

Abstract: 870,919. Radio receiver control arrangements RANK ORGANISATION Ltd. March 10, 1959 [Jan. 31, 1958], No. 3268/58. Class 40(5) [Also in Group XVIII] In a subscription television system incoming television signals at terminal 1 are accompanied by control signals either sent over the same conductor or applied at terminal 1a, these control signals being applied to a circuit 3 which controls the rate at which a metering circuit 4 is advanced. The circuit 4 is preferably coin controlled; the insertion of a coin completes a circuit to permit incoming signals to be applied to receiver 5, the circuit remaining completed for a time determined by the reception of control pulses in circuit 3. Thus in the event of failure of programme signals or if the manual control switch 2 is opened the metering circuit 4 ceases to run and the unexpired portion of the period corresponding to the value of the inserted coins is still available for the user. The meter circuit 4 is not necessarily coin-freed; it may alternatively merely record the amount of use of the receiver at a rate determined by the control signals. Further positions may be provided on the manual control switch 2, which may then effectively be a channel selection switch; to permit the reception of signals other than the televisionsubscription signals, Fig. 2 (not shown).
