Title: Shock absorber
IPC: F16F7/04
Filed: 1923-07-05
Abstract: 200,812. Laforge, P. July 13, 1922, [Convention date]. Vibration-dampers. - Relates to shock-absorbers for motor vehicles &c. of the kind comprising two juxtaposed relatively rotatable members with co-operating inclined surfaces which are pressed together by the action of a spring, one member being connected to one of the parts between which relative motion is to be controlled and the other member being in frictional engagement with a disc or drum connected to the other of the parts in such a way that free motion is permitted in one direction and retarded motion in the other direction. According to the invention, the two members with co-operating inclined faces and the disc or plate in frictional engagement with one of these members are mounted on a common shaft by means of a key and wedge device which under the action of the spring compensates automatically for any wear occurring between the components. The shock absorber comprises a base-plate 1 securing to the vehicle &c. and a freely rotatable spindle 2 which carries two members 4, 5 which are arranged to coact through three inclined surfaces on each member. The member 4 is in frictional engagement with the base-plate 1, preferably by a washer 3, while the member 5 is connected through an arm 5<d> with the axle. Wear is automatically taken up by means of a spring-controlled wedge 7. The member 5 can turn freely in one direction, but in the other direction the member turns relatively to the member 4 until a screw 9 engages an abutment 4d, the inclined surfaces meanwhile riding on one another. The members then turn together and a braking action is caused by friction between the member 4 and the base-plate 1.

Title: Improvements in or relating to armature-winding machines
IPC: H02K15/09
Filed: 1960-05-18
Abstract: 888,591. Coil-making machines. ELECTRISCHE APPARATEN EN METAALWARENFABRIEKEN R. BLIK N.V. May 18, 1960 [May 21, 1959], No. 17561/60. Class 35. An armature winding machine has wire guides which move radially as well as longitudinally of the armature during winding to fill the armature slots uniformly, the amplitude of the radial movement varying during winding. Movable frame 2 carries rods 3 which slide in guides 4 on housing 1, and carry platform 5 having a central opening. Bell-crank levers cause wire guides 6 (only one shown) on platform 5 to move radially on rotation of ring 9 which is held against a stop by a spring. Fastened to pulley 11, mounted on platform 5, is a chain 10 attached at its other end to ring 9 so that rotation of pulley 11 causes ring 9 to rotate. Shaft 17, on whose upper end the armature to be wound is mounted, carries a slidable but non-rotatable pinion 18 engaging with rack 19 having a cam-follower 20 at its other end, lying in a groove 21 on cam 22, the groove being shaped so that rack 19 causes shaft 17 to rotate through a predetermined angle each time the cam completes a half-revolution. A diametral groove 23 in cam 22 carries adjustable member 24 with a driving-pin 25 which moves frame 2 vertically as cam 22 rotates. The cam is rotated by main driving-shaft 26 driven by an electric motor through a belt and pulley 27. An endless chain 16 extends round pulleys 12, 13 and 14, 15 mounted on platform 5 and frame 2, respectively, and adjustable stops 39, 40 on the chain engage with abutment members 36, 37 as frame 2 is lowered and raised, respectively. This engagement causes chain 16 to move, rotating pulley 11, attached to pulley 12, and causing the wire guides to move radially inwards. Abutment members 36, 37 are slowly moved vertically during winding by cranks driven by a belt from pulley 28 to vary the amplitude of this radial movement. Operation of lever 42 lowers central shaft 17 for removal of the wound armature. U.S.A. Specification 2,381,750 is referred to.

Abstract: 508,622. Welding rails, girders, pipes, &c. RENNER, O. June 13, 1938, No. 17570. Convention date, June 12, 1937. [Class 83 (iv)] In butt-welding rails, girders, pipes, &c. of steel or other metal, the work parts with metallically bright ends are pressed together with their ends in contact and the adjacent peripheral surfaces, e.g. over a distance of 25-80 mms. on either side thereof, are heated by one or more flames, preferably oxy-acetylene or other high temperature frames, to such a temperature that the ends to be welded, which are pressed together, are by heat conduction brought to a temperature below the solidus and are thus pressure welded. The heating zone may thus be kept under observation throughout the heating operation. If desired, an additional preliminary pressure e may be applied when the temperature has reached 600‹ to 700‹ C. The parts may be preheated, e.g. to 800-1000‹ C., by cheap flames. Two closely adjacent joints such as between rail ends and intermediate pieces inserted in the gap between rail ends in situ, may be welded simultaneously. The Specification as opento inspection under Sect. 91 states that the preliminary pressure may be applied when the parts are cold. This subject-matter does not appear in the Specification as accepted.

Title: A process for the preparation of alumina from clay
IPC: C01F7/26
Filed: 1920-06-29
Abstract: Sulphur oxides; alkali metal compounds, obtaining from complex silicates.  Potash-bearing clay, or similar impure aluminous material is decomposed with sulphuric acid and potash alum is obtained by cooling the liquor resulting from the hot lixiviation of the treated mass.  Potassium sulphate recovered at a later stage is then added to produce a further yield of alum and the latter is calcined to give alumina, potassium sulphate and oxides of sulphur.  In an example, air-dried clay is ground and mixed with rather less than the equivalent of chamber acid.  The reacting mass is allowed to stand 24 hours and the action is completed and the silica rendered filterable by heating to 200 DEG  C. The resulting mass is lixiviated with hot water to give a solution of about 35 DEG  B<\>ae which on cooling deposits potash alum.  A further crop of crystals is obtained by adding powdered recovered potassium sulphate to the cold liquor.  The combined yields after de-hydration are calcined and the sulphur oxides evolved worked up into sulphuric acid for treating fresh quantities of clay.  The residue after calcination is extracted at 100 DEG  C. with an aqueous solution of potassium sulphate saturated in the cold.  On cooling, the liquor yields potassium sulphate crystals and a mother liquor which is used repeatedly.ALSO:Potash-bearing clay, or similar impure aluminous material is decomposed with sulphuric acid, and potash alum is obtained by cooling the liquor resulting from the hot lixiviation of the treated mass.

The alum is introduced into the hottest part of a furnace, which is preferably of the revolving-tube type in order to avoid the formation of a tough, hard mass during the dehydration of the crystals.  The latter are finally heated to 700-800 DEG  C. in the same kind of furnace, to expel oxides of sulphur which are worked up into sulphuric acid for treating fresh quantities of clay.  The residue after calcination is extracted at 100 DEG  C. with an aqueous solution of potassium sulphate saturated in the cold.  On cooling, the liquor yields potassium sulphate which is mainly used for the production of alum as described above.

Short - time movements.- Comprises means for timing short intervals, such as the duration of an echo. In the preferred embodiment subaqueous sounds are emitted at regular intervals in such a way that for a given depth the echo is heard when a rotating indicator is in a definite. position corresponding to that depth. The indicator consists of an incandescent lamp 63 carried by a disc 62 fixed to the rotating shaft 77. Current is supplied to the lamp from a battery 24 through slip-rings on the fixed plate 71, and a slit 64 in front of the lamp is visible through the transparent ring 139, Fig. 1, in an opaque panel bearing two scales 140, so that the position of the illuminated slit can be noted against one of these scales at the instant when the echo is heard, the observation being facilitated by the rhythmic recurrence of the phenomena. Two alternative speeds of the shaft 77 with two different durations of the emitted impulse can be employed, a two-speed gear 96 making this possible. The shaft is driven through gearing from a motor 91 under the control of a main switch E, potentiometer 109, and field rheostat. A frequency meter 59 enables the speed of the motor to be adjusted in accordance with the calibration of the scales 140.

Abstract: 1434072 Porous tubes RHONE-POULENC SA 13 April 1973 [14 April 1972] 17988/73 Heading F2P [Also in Division B1] A support element for a tubular membrane for use in reverse osmosis or ultrafiltration comprises a porous and/or perforated support tube and a shrunk textile sheath gripping the outer surface of the tube. The term "shrunk" is used to exclude material which is reduced in one dimension while being increased in another. The textile is preferably synthetic, particularly of heat-shrinkable polymers, e.g. prestretched polyvinyl chloride and mixtures of polyvinylchloride and chlorinated polyvinyl chloride. Such polymers may be used as the weft with a warp made of unshrinkable material, e.g. polyolefin or glass, so as to be shrinkable in a radial direction. The sheath is placed over the tube, which may be made of metal or polymeric material, and heated to cause it to shrink around the tube. Several sheaths may be superposed. The membrane, e.g. of cellulose acetate, may be applied in the usual way, i.e. as a preformed tube or in situ from solution in which latter case it is preferred to seal temporarily the pores of the textile. Specification 1,434,071 is referred to.
