Title: Improvements in the formation of holes by spark erosion
Inventor: HULLEY RICHARD WALTER
IPC: F01D5/14
Filed: 1958-06-18
Abstract: 856,983. Making turbine blades; drilling by spark erosion. ROLLS-ROYCE Ltd. June 10, 1959 [June 18, 1958], No. 19565/58. Classes 83 (2) and 83 (4). One or more transverse holes are formed in the wall of a longitudinal boring 18, Fig. 2, of a metal article, particularly a gas-turbine blade, by spark erosion using an electrode 15 with a longitudinal portion 16 and one or more lateral projections 17. The transverse holes may be used to interconnect cooling passages 18, 19 in a turbine blade as described in Specification 856,674. For initial setting the electrode, an indicator lamp 23 and battery 22 are used to ensure that the electrode is out of contact with the wall of the boring. A separate D.C. supply is used for the erosion during which the replaceable copper or brass electrode 15 is fed downwardly and is vibrated longitudinally by an electromagnetic vibrator. Dielectric fluid is fed through a capillary bore in the electrode and the operation may take place in a bath of dielectric fluid such as paraffin. The blade is mounted on a table 11, Fig. 1 (not shown), capable of horizontal movement in two directions.

Title: Improvements in or relating to gramophones and like sound reproducing machines
IPC: G10K13/00
Filed: 1922-07-21
Abstract: 207,222. Verity, C. H. July 21, 1922. Tone-arms; sound-boxes; tone-arms, resiliently supporting.-In a gramophone or telephonic loudspeaker, an electric or gas heating device is placed within the amplifying chamber or sound-channel for the purpose of improving the tone and volume of the sound by creating free circulation of the vibrating air. The invention may be applied to either a gramophone or a loud-speaker independently, but when used with a gramophone the modified sound thus emitted therefrom may be transmitted to one or more loud-speakers by mounting one or several microphones in holes in the sides of the horn or other part of the soundconduit. In the apparatus shown, an electric heater h of triangular shape, consisting of high resistance wire wrapped round mica, is mounted in slots in the metal or fire-brick throat j of the horn k of a gramophone. The circuit of the heater may comprise two switches, one being operated by opening and shutting the hinged lid l of the casing. Small holes g are made in the sound-box c, at the back or side of the diaphragm, and another hole g is formed at the bottom of the elbow f to which the tone-arm is pivoted. By this means, a current of air is induced in the sound-conduit, passing into it through the inlets g, which may be adjustable. The weight of the tone arm is partly counterbalanced bv a, spring e. The sound-conduit has a glazed vitreous lining, and the horn may be made of four flat or curved glass sheets, held together by angle-pieces. Sound emitted from the horn is reflected from the lid 1, the inclination of which is adjustable. In a modification, the casing and horn are so designed that the sound is emitted through a vertical aperture, being directed horizontally over the turntable. 'The hinged lid is dispensed with, double doors being provided over the turntable. Alternatively, the horn may be eliminated, and the throat arranged to face away from the turntable. The Provisional Specification describes also the following arrangements. An electric heating element may be wound around the outside of the throat of the horn or in grooves around the inside, and the extent of heating may be controlled by a variable resistance. The heater may be wound on a conical or pyramidal frame, and may be mounted in various ways, the throat and the heater being readily detachable. " Electric bulbs " or hotair conduits may be used as heaters, and the throat may be surrounded by a packing of heatinsulating material. Joints in the sound-conduit mav be Enclosed in fiexible casings. The soundbox may have more than one diaphragm, each of which may have holes therein for the passage of air. A shell-shaped horn may be used. The throat containing the electric heater may be so mounted that it can be turned laterally, either to co-operate with the horn, or to emit sound through an opening in a wall of the casing of the machine.

Abstract: 401,436. Cleaning and disinfecting tobacco pipes &c. HELLMANN, B., 290, Nordstrasse, Z³rich, Switzerland. July 15, 1932, No. 20106. [Classes 81 (i) and 130.] Tobacco pipes, cigar and cigarette holders, and the like are cleaned and disinfected by filling them with a solvent consisting of a mixture of acetone or the like, a nitrated hydrocarbon such as nitro-benzol, and a dilute mineral acid such as hydrochloric acid. The acid may be replaced by acetic anhydride in cases where the solvent is likely to come into contact with metal parts. After being subjected to the solvent for some time, the pipe &c. is rinsed out with water and dried. Fig. 1 shows a wooden member 5 formed with holes for supporting pipes in position for treatment with the solvent, the mouthpiece end being closed by a rubber cap 6 and a wood plug 7. An upright stand is used for cigar and cigarette holders, which are held therein in an inverted position. A particular example of solvent described consists of 76 parts by weight of acetone, 10 parts of hydrochloric acid or acetic anhydride, 4 parts of nitro-benzol, and 10 parts of water.

An anti-skid brake system for a wheeled vehicle having an engine, drivable wheels and a drive-line connecting drivably the engine and the drivable wheels comprises a master brake cylinder 276, fluid pressure-operated wheel brakes and a brake release valve 126 including a pressure movable control piston member 134, a pressure compensating element 152 in fluid communication with the brake pressure passage and connected to member 134, one side of member 134 being connected to a source of pressure fluid, a speed comparator forming in part a fluid connection between a release valve actuator, for selectively pressurizing and exhausting the one side of member 134, and the pressure source, a pressure signal proportional in magnitude to the driven speed of the driveline being obtained from a governor valve assembly forming part of an automatic control valve circuit for controlling gear shifts and a deceleration pressure signal being obtained from a sensor 258 including a valve element 264 moved by an inertia mass 274 responsive to acceleration forces acting in the direction of motion of the vehicle so that when the vehicle decelerates as normal braking continues the governor pressure acting on the speed comparator or wheel slip control valve element 218 will decrease and the pressure on the other side of the element will also decrease because the valve element 264 will rotate and uncover orifices 270. If wheel slip occurs, however, a decrease in governor pressure will not be accompanied by a corresponding reduction in vehicle speed, causing a pressure build up to shift valve element 218 and move sleeve 152 to allow an increase of volume available to the fluid acting on the brake cylinders and thus release the brakes.
