Title: Improvements in and relating to rotary electric ignition current distributors or timers
IPC: F02P7/00
Filed: 1922-08-14
Abstract: 201,055. Marks, E. C. R., (Leich Electric Co.). Aug. 14, 1922. Rotary distributors; contacts.- In a rotary distributor of the type in which a rotating contact member contacts successively with a number of relatively fixed contacts a steady contact is assured by arranging the rotary contact member to form polar projections of a magnetized member, the fixed contacts being of magnetic material and by their attraction preventing faulty contact due to the rebound and consequent vibration of the fixed contacts when engaged by the movable contact-member at high speeds. The fixed contacts 31 are mounted on flat springs 33 secured by insulated terminal screws 41 around a metal casing 5 which is provided with a timing arm 12 and a retaining spring 8. The rotary member consists of a flanged non-magnetic sleeve 14, 21 mounted on the timing shaft 13 to which is secured by screws 25 of magnetic material two permanent magnets 22, 23 separated by an insulating ring 24 and provided with projecting pole pieces 26, 27 the tips of which act as contact surfaces. The projections 26, 27 are of opposite polarity, the gap in the magnetic circuit formed by the members 22, 23 and the screws 25 being composted by the fixed contacts 31 as they are in turn engaged by the rotary contact member to complete the respective ignition circuits. The insulating ring 24 projects beyond the periphery of the magnets 22 23 to prevent the contacts 31 from engaging portions of the magnets other than the projecting tips 26, 27, and in order to prevent wear due to the rubbing of the fixed contacts on the ring 24 rigid non- magnetic arms 40 are secured below the contactcarrying springs 33 so that the contacts 31 are normally clear of the insulating ring 24.

Abstract: 814,440. Semi-conductor vibration indicators. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. July 12, 1957 [July 23, 1956], No. 22146/57. Class 40 (3). [Also in Group XXXVIII] Vibration of a rotating body causes the spot produced by a beam of radiation to traverse a semi-conductor assembly comprising a centre zone of one conductivity flanked by two zones of opposite conductivity, the electrical signals produced are proportional to the magnitude of vibration. Fig. 3 shows the rotating body 69, the bearings 57 and 71 are seismically supported by the flat springs 63, 65, 75 and 77. Light beams 11A and 11B from the sources 1A and 1B are concentrated by the lens systems 15A and 15B and reflected on to the semiconductor assemblies 3A and 3B by the reflecting surfaces 61 and 73 attached to the bearings. In operation the seismic mounting allows vibration in a plane substantially parallel to the base 67, the reflecting surfaces move towards and away from the light sources causing the spot at which the reflected light beam strikes to traverse the semi-conductor assemblies. The apparatus is dimensioned to limit the traverse to the centre zones 7A and 7B of the assemblies. The output voltages produced across the loads 17A and 17B are indicative of the magnitude of vibration. In a second embodiment a pellet of radio-active material, producing alpha, beta or gamma rays, is inserted in the bearing housing, a beam of radiation escapes via a small hole in the housing and operates on the semi-conductor assembly.

Title: Safety device for tannery machines with semi-automatic opening and closing movements
IPC: F16P5/00
Filed: 1953-08-12
Abstract: 733,965. Machinery safety devices. MASCHINENFABRIK TURNER AKT.-GES. Aug. 12, 1953 [Oct. 7, 1952; Dec. 4, 1952], No. 22228/53. Class 80 (4). [Also in Group VIII] A device in tannery machines with semi-automatic closing and opening movements, interposed in the linkage operating the clutch for said movement, comprises a hydraulic pressure cylinder, a movable piston and valve connected to the pressure chamber of the cylinder such that, upon actuation of the valve the pressure chamber can be evacuated and the piston can enter therein, thereby immediately disengaging the clutch. The device may be operated solely by a safety flap closing off the danger zone, or may in addition be opened by means of a separate safety pedal. In Figs. 2 and 3, the safety device comprises a pressure cylinder 19 having a chamber 42 in which is the fluid which may be released into a reservoir 31 by rotation of the threaded spindle 40 of a valve, by means of a draw cable 29 and if desired an additional cable connected to the pedal 35. The rod 17 is connected to a pedal 16, and is attached to the safety device by the bifurcated end 18. Its movement is normally imparted to a rod 22 in the chamber 42, thereby putting the pedal in communication, through a lever 25, shaft 26 and lever 27, with a clutch cone 38, whereby the rotating shaft 8 is enabled to drive a shaft 12 operating the opening and closing movement. When, however, the valve is actuated by the movement of the safety flap or pedal 35, the spring 32 on lever 33 is able to move the rod 22 into the cylinder, and rotate shaft 26 thereby disengaging the clutch. In order to recommence operations, the valve (which has closed due to the spring 34) is operated manually and the counter piston 23 then withdrawn by rotating the handle 24 thereby drawing the fluid back into the cylinder. The valve is allowed to close and the counter piston screwed back to reestablish the original distance between the fulcrums of lever arms 20, 25. In the embodiment shown in Fig. 5, the rod 22 and counter piston are angularly arranged, preferably at 90 degrees to each other, in a pressure chamber, and with their associated guide bushes 43 and 44, are of such dimensions as to be interchangeable. The valve 30 is guided in a sleeve 46 comprising a threaded member 47, said sleeve forming also the reservoir. The valve is normally kept in a closed position by the helical spring 49 arranged round its spindle 45.

Filed: 1930-07-29
Abstract: In the treatment of ligneous vegetable materials, which are rich in resin and turpentine with a dilute alkaline lye of 1-2 DEG  B<\>ae. for a prolonged period--6 to 24 hours--at ordinary temperatures between 15-20 DEG  C., the materials may be further treated with steam whereby turpentine can be separated and condensed.  The lye is then strengthened to 2 DEG  B<\>ae and the material again treated under heat to separate the resin.  The Specification as open to inspection under Sect. 91 (3) (a) also states that the liquor obtained can be treated with strong mineral acids to obtain chemically pure carbon.  This subject-matter does not appear in the Specification as accepted.ALSO:In the treatment of ligneous vegetable materials which are rich in resin with a dilute alkaline lye of 1-2 DEG  B<\>ae for a prolonged period-6 to 24 hours-at ordinary temperatures between 15-20 DEG  C., for the production of lignin which can be converted into cellulose, the lye after the treatment contains a considerable proportion of sodium acetate from which acetic acid can be recovered by known methods.  Materials which are rich in turpentine can be treated as above and then the turpentine removed by treatment with steam, and the resin by heating with a strengthened lye.  The bark from the trees can be treated by this method to obtain acetic acid.  The acetate produced can be used to obtain substantially pure acetone.
