Title: An improved centrifugal type reduction mill
IPC: B02C13/09
Filed: 1936-03-31
Abstract: 469,971. Impact pulverizers. AINSA, G. F. March 31, 1936, No. 9530. Convention date, April 1, 1935. [Class 59] An impact pulverizer comprises a rotating bowl-like element into which material is fed, the material being thrown by the bowl onto a surrounding impact surface and the coarse material is accumulated and led back to the bowl for further centrifugal action. The shape of the bowl may be such as to retain a layer of material on its surface. As shown, fresh material from a shoot 39 falls into a rotary drum 31 provided with lifting vanes 32 which deposits fresh and oversize material into a shoot 33 from which it falls into a rotary bowl 12. The material is thrown by the bowl 12 onto a stationary or rotary impact cylinder 27 where it is crushed and discharged into the drum 31, the fines being floated off over a ring 49 into a shoot 46. The impact cylinder 27 and drum 31 are mounted on rollers 21, 22 and are driven by a pinion 24 and gear ring 23. The lining 28 of the cylinder 27 may consist of a series of renewable rings or as shown in Fig. 3 may consist of two spaced cylinder liners 58, 59, the space between and back of the liners being filled with the material being pulverized, the former liner being in the line of flight of the material leaving the bowl and forming an impact surface. The bowl may be provided with a renewable lip 52 of abrasive material secured by dowel pins 54. An annular casing 30 overlaps the back of the bowl to prevent escape of the material and a rubber lined baffle 35 prevents material being discharged directly into the drum 31. The bottom of the baffle 35 is hinged at 37 to discharge material accumulated in the cylinder 27 at starting. A disc 40 with conical periphery 41 is secured in the drum 31 and forms a slit with the back thereof through which the fine material is discharged.

Patent GB-573531-A (GB)
Title: Improvements in or relating to the reduction of the peracid content of oxidation reaction products
Filed: 1941-07-28
Abstract: In the oxidation of acetaldehyde to acetic anhydride, the quantity of per-compounds present in the reaction mixture is p  reduced to below 3 per cent by interrupting the oxidation, reducing the oxygen pressure, and raising the temperature above the oxidation temperature and within the limits 25-50 DEG  C.  If oxygen is the oxidizing atmosphere, the atmosphere during the reducing stage may be air or nitrogen.  The oxidation may be effected continuously, a portion of the reaction mixture being withdrawn, reduced and returned to the reaction.  In an example, a mixture of paraldehyde, vanadic acid (as depolymerizing agent) and p-toluene sulphonic acid is oxidized with oxygen at 33 DEG  C. and 10 lb. pressure; after a time, the oxygen pressure is reduced and air admitted, the temperature being passed to 40 DEG  C.  In another example, nitrogen is used instead of air, the temperature being 43 DEG  C.  Specifications 443,151 and 446,259 are referred to.  When the reaction product is worked up, remaining per-compounds may be removed by manganese salts or reducing agents.
Patent GB-1469045-A (GB)
Title: Transmission detector
IPC: G01N21/85
Filed: 1975-03-07
Abstract: 1469045 Photo-electric smoke detector CERBERUS AG 7 March 1975 [8 March 1974] 9668/75 Heading G1A A smoke or carbon monoxide gas detector includes two radiation beams 11, 12 transmitted along paths of different lengths but which include the same reflectors in different sequences whereby the beams are affected equally by alterations of the reflectance of the reflector surfaces due to aging or soiling, so that this effect cancels, but are affected by the presence of smoke to different extents since the attenuation caused thereby is a function of path length. A preferred embodiment has a housing 1 with openings 2 for ingress of smoke-laden air and with seven mirrors 4a-4g disposed at seven sides of an octagon facing inwardly. At the eighth side is a radiation source 6 emitting light, infrared or ultraviolet to a beamsplitter 10 which is a roof prism or semi-transmissive mirror and which forms the beams 11, 12. The measuring beam 11 travels via mirrors 4c, 4f, 4a, 4d, 4g, 4b, 4e to the beam-splitter thence to a photo-electric device 8. The reference beam 12 travels via mirrors 4a, 4b, 4c, 4d, 4e, 4f, 4g to the splitter thence to a photo-electric device 7. The measuring beam 11 has a path length of 7.39 times the separation of the opposed mirrors while reference beam 12 path length is 3À06 times this separation. The devices 7, 8 thus receive beams of which the difference in attenuation by the smoky air is that due to a path length difference of 4À33 metres where the separation is 1 metre. To avoid disturbances due to ambient light the source may be pulsed and the receiver connected in a coincidence circuit with the source pulse drive. The embodiment of Figs. 4-6 (not shown) uses two synchronously driven radiation sources (18, 19) aligned differently to provide the two beams (12, 11) respectively and the mirrors are disposed at the sides of a pentagon. An alternative embodiment Fig. 8 (not shown) employs thirteen reflectors on the sides of two contiguous octagons (27, 28). The measuring and reference beams may have different spectral compositions and the respective photo-electric device is sensitive to the relevant spectral range. A duel photoelement with two spectrally different filters may be employed. The embodiment of Fig. 9 (not shown) uses an internally reflective cylindrical sheath with a laser source.

Title: Improvements relating to hydraulic turbines and wind motors
IPC: F03D3/06
Filed: 1946-03-28
Abstract: 610,149. Hydraulic turbines; wind motors. BURDICK, C. L. March 28, 1946, No. 9677. [Class 110 (iii)] A hydraulic turbine or wind motor of the kind having a shaft on opposite sides of which are mounted one or more blades adapted to oscillate about axes at right angles to the shaft axis, each blade on one side having its plane at right angles to the plane of each blade on the other side, the blades are oscillated through link mechanism by a cam splined to the shaft, the cam engaging a trunnion normally fixed in position. Pairs of flat blades 4 are mounted on shafts 3 which are journalled in the main shaft 1 at right angles thereto. The shafts 3 are interconnected by a link 6<1> and cranks 5 and are connected by a further link 6 to a cylindrical member 7 slidably keyed to the shaft 1. A stationary detent 10 engages a cam groove 9 on the member 7, so that the latter reciprocates longitudinally as the shaft 1 rotates, thereby oscillating the blades 4 through an angle of 90 degrees and back during each revolution of the shaft 1. The detent 10 is carried by a slidable member 14 which is normally arrested by a detent 11 having a wedge-shaped end which engages an opening in the member 14. The detent 11 may be wholly or partially withdrawn to put the machine wholly or partially out of action. The shaft 1 is mounted in spherical bearings 2. A number of such shafts may be coupled together in alignment; flexible couplings may be used. Wheels 15, freely mounted on the shaft 1 act as guards to prevent damage to the blades as by touching the bottom or shore. The machine may be mounted on suitably anchored floats or boats, and may drive an electric generator with which may be associated storage batteries to maintain a constant supply.

Title: Improved bearings and methods of making the same
IPC: F16C33/14
Filed: 1948-04-07
Abstract: 678,363. Making bearings. GENERAL MOTORS CORPORATION. April 7, 1948 [April 11, 1947], No. 9692/48. Class 83 (ii). [Also in Group XXXIV] A method of making a bearing comprises immersing a bearing blank, having a surface of aluminium, in a bath of soft corrosion - resistant bearing metal such as lead or lead base alloy, abrading the bearing surface while so immersed and thereby forming indentations therein, and withdrawing the blank with the indentations filled with bearing metal, and thereafter finishing the blank to the desired shape and dimensions. In a method of making a bearing surface of aluminium having surface indentations which are filled with lead or a lead alloy, a strip of pure aluminium, aluminium alloy or preferably aluminium bonded to a supporting strip of steel, is passed through a bath 14 of molten lead or lead-tin alloy containing a deoxidizer such as calcium, the bath containing revolving wire brushes 16 which abrade the surface of the aluminium strip. The strip is then passed into a second bath 17 of molten lead or lead-tin in which a revolving knurling roller 18 forms indentations in the aluminium surface. The blank is then immersed in a third bath 20 of the above molten metal in which rollers 22 guide the strip and hold it submerged in the bath. In this bath the previous coating is dissolved and an agitator 20a may be provided to ensure that none remains in the pits or depressions. The strip is then formed to bearing shape and machined until the grid pattern is exposed. With certain modifications, the process may be performed in two baths or only one bath. Specifications 536,414 and 678,423, [Group II], are referred to.

IPC: F16K31/06
Filed: 1990-09-21
Abstract: In a solenoid valve, which can be used in particular as an electropneumatic control and regulating valve, provided inside a housing (1) is an armature arrangement (21, 23) which can be displaced axially by energising a coil (3) and moves alternately into a closed or open position with respect to openings from inlet and outlet lines. In order to achieve small and large cross-section ventilations (small signal and large signal respectively), the armature arrangement is constructed in two parts in such a manner that an inner armature (23) is guided such that it moves axially in an outer armature (21). When the coil of the solenoid valve is energised less, the inner armature can move axially inside the outer armature and acts with respect to a small cross-section energy inlet (small signal), while, in the event of the coil (3) of the solenoid valve being energised more powerfully, the outer armature (21) interacts with the inner armature to release a large cross-section for the energy inlet (large signal). <IMAGE>
