Patent GB-1551390-A (GB)
Title: Cooling arrangement for an internal combustion engine or in a compotent therefor
IPC: F01P3/10
Filed: 1976-07-08
Abstract: The coolant flows, with a fall in pressure, out of an outer chamber (6, 23) through constricted flow apertures (11, 24) into an inner chamber (12, 12a, 20) adjacent to the wall (3, 21) to be cooled, which latter chamber is connected to a discharge pipe (17). The intention is that for a high mechanical load-bearing capacity of the wall to be cooled only low temperature stresses should occur. To this end, cooling depressions (12, 12a, 20), separated from one another by lands (13) and open on the side remote from the incident heat, are provided in the wall (3, 21) to be cooled. In addition, each flow aperture (11, 24) is trained on an area of the opening of a cooling depression close to the wall. In addition, at least one further area of the opening of the cooling depression opens into a discharge duct (16, 25) running transversely to the direction of flow of the coolant and connected to the discharge pipe (17). The coolant is fed to the cooling depressions, deflected on their bases and immediately drained off again through the openings. In this way, constantly fresh coolant strikes those parts of the wall to be cooled resulting in optimum heat dissipation and hence in optimum cooling of the wall parts. <IMAGE>

Title: Process for the production of steel in the thomas converter
IPC: C21C5/28
Filed: 1935-10-18
Abstract: Steel with the characteristics of steel produced in the basic Siemens-Martin furnace is produced in a Thomas converter by subjecting a crude iron, the composition of which is suitable for treatment by the Thomas process, to a normal blowing in a Thomas converter, the temperature of the bath being increased to at least 100 DEG  C. above that normally employed by the employment of blast air preheated to 300-700 DEG  C., so that the manganese is constantly reduced from the slag and such a manganese content, 0,3-0,7 per cent, attained in the steel that an addition of ferro-manganese as a deoxidizer is unnecessary.  To assist the action the lime may be used hot as it comes from the kiln.

IPC: B28C5/20
Filed: 1949-11-10
Abstract: 679,132. Mixing appliances. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 12, 1951 [Nov. 10, 1949], No. 28852/49. Class 86 In a mixer of the type incorporating a rotary drum fitted with internal buckets the buckets are movable in relation to the drum in such a way that during their upward movement they have one edge bearing against or near the drum and can lift the material being mixed, but at other parts of their cycle they can move away from the drum. The buckets 1, Fig. 3, within the drum 5 of a concrete mixer are mounted on shafts 3 which are freely rotatable in bearings carried by one or both end walls of the drum so that the edges 6 of the buckets on the upwardly moving part of the drum 5 rest against the peripheral wall of the drum and at the top of the drum pivot under gravity so that the edges of the buckets in the downwardly moving part of the drum are spaced away from the wail. In Fig. 4, the shafts 3 carry arms 8 with cam followers 9 which run in a cam ring 10 fixed to the mixer frame, by which means the buckets can be made to swing at a given point in the revolution. The angular setting of the arms 8 may be varied for mixes of different consistency and the cam ring may be angularly adjusted to vary the timing of the tilting cycle of the buckets to give quicker mixing for a particular mix or to speed up discharge; the chain lines in Fig. 4, indicate a position of the cam ring suitable for discharging the mix. In an alternative arrangement, Figs. 5 and 6. (not shown), the buckets have alternately long and short shafts 3 having means to engage projections of different lengths near the top of the drum to produce differently timed tilting of alternate buckets and near the bottom of the drum a common cam is provided to swing all the buckets back into position with an edge adjacent the drum wall. A third projection may be provided which may be brought into position to cause all the buckets to tilt to cause discharge.

Abstract: 522,247. Rod vibrators ; acoustic resonators. NU TONE CHIMES, Inc. Oct. 7, 1938, No. 29125. Convention date, Oct. 7, 1937. [Class 13] In a signalling device of the kind comprising a resonance chamber having an aperture opposite a vibratable bar adapted to be set in vibration by a striker, the vibratable bar 5 or 6, Fig. 1, is arranged to vibrate in two or more full antinodal sections extending between three or more nodal points N, Fig. 5, in combination with a resonator 7 or 8 which has an opening 20 adjacent an antinode of the bar and is arranged parallel to the bar in such a location that a striker may be placed at a point of the bar beyond the resonator. As shown, two resonators and two bars are provided. The bars are supported at two nodal points by cushioned screws 16 on brackets 11. Two strikers 26 operated by solenoids 21 are provided between the bars. The top striker is confined on the left hand side by a stop 29a so that it can strike the bar 6 on the right when its solenoid is energized but returns idly to normal position when the solenoid is de-energized. The lower striker is free on both sides and strikes one bar when its solenoid is energized and strikes the other bar on its rebound when the solenoid is de-energized. Two different signals are thus available depending on the solenoid energized. The resonators are closed at the top and are tuned by means of an adjustable plug at the lower end.

Abstract: 879,431. Wiredra wing. DRAHTZIEHMASCHINENWERK GRUNA VEB. Sept. 11, 1958,.No. 29195/58. Class 83 (4). In a wire drawing machine with diameters of the drawing stages such that peripheral speeds of the drawing stages are higher than the speed of the wire, the relative speed between the wire and one of the intermediate drawing stages is lower than for the other drawing stages and the said intermediate stage is immediately followed by a rockable roller switch actuable by wire tension to continuously control the speed of a winding bobbin as the diameter of the finished coil increases. A fine-wire drawing machine 3 comprises drawing cones 1, 2, the wire 5 being supplied from a bobbin 4 and reeled on to a delivery bobbin 8 through a laying device 7: The speed of the delivery bobbin 8 is controlled by a switch 9 located intermediate the drawing stages and having a spring-biased rockable lever 10 (Fig. 2, not shown), the switch actuating a draw-on magnet controlling an infinitely variable transmission drive of the bobbin. The wire slides at all the drawing stages until the increased diameter of the coil on the bobbin 8 increases the speed of the wire sufficient to cause sliding to cease at stage 6 whereupon the tension in the wire is increased in the vicinity of the switch 9, the tension pulse rotating the lever 10 to operate a microswitch 18 and decrease the speed of the bobbin drive. During the period of maximum tension sliding still continues at all other drawing stages.
