Filed: 1935-08-17
Abstract: 461,566. Magnetos. RAWLINGS, G. W. Aug. 17, 1935, No. 23135. [Class 35] In an electric generator of the type employing permanent magnets and having a pressed metal casing, one end of which locates two anti-friction bearings for the armature spindle while the body of the casing is concentric therewith and receives the field magnet, the two antifriction bearings comprise a single common ball-bearing member located in the end of the casing. The casing is in two parts a, b, the enlarged portions receiving the field magnet p, and the two parts are secured together by spinning the edge b<2> of the part b over a shoulder of the part a. A bearing member c<1> fits the conical and cylindrical parts of the casing member a. The armature spindle has a fixed ball race e and an adjustable ball race f, formed integral with a driving pulley g secured by a lock nut d<2>. The pulley has an annular grove g<2> fitting over an extension a<3> of the casing and accommodating a felt sealing ring h. A distance piece o is fitted into the casing to prevent movement of the bearing member c<1>. The armature windings are connected at one end to the spindle d and at the other end to an insulated cap j against which bears an insulated spring-loaded contact l carried by the casing part b.

The valve-member 66 is shown in perspective in Fig. 6 and in planar projection in Fig. 8 where the valve-member is illustrated as uncovering one port 64 and two ports 62, i.e. about a 25% reduction from full capacity, and where ports 102 communicate with a port 64 at a location such that liquid would only be injected after the working chamber is closed from the inlet. The auxiliary ports 100-110 decrease in cross-section towards the discharge end so as to reduce the amount of liquid injected as the capacity reduces at constant pressure or to keep it constant if pressure increases as capacity decreases, the compressor being described in use in a system of the latter type Fig. 2, (not shown). An alternative embodiment is also described Figs. 11 to 15, (not shown) in which the inlet port is axial instead of radial, the valve turning means are altered, the helical edge of the valvemember is not stepped, and the pairs of auxiliary bores are replaced by single bores leading into suitably shaped slots in the circumference of the valve-member.

Abstract: 1446390 Automatic control BETHLEHEM STEEL CORP 3 June 1974 [5 June 1973] 24415/74 Heading G3N An apparatus for automatically measuring and controlling the net-dry-weight of discrete quantities of moisture-containing materials computes an actual desired weight in dependence on moisture-content, target-dry-weight and dryweight error ensuing from all previous weighings. As shown, an instant measure of coke to a hopper is obtained from a voltage follower 10 and modified by an instant moisture-content measure, from a nuclear device 18, in a multiplier 20 to produce an instant dry-weight. A device 24 subtracts the dry-weight from a reference value for a weighing from a module 26 an adds it to a reference value plus preceding error value held in a sample-and-hold module 30. The resultant is held in a sample-and-hold module 28 and applied to a divider device 34, together with the moisture-content measure, and the resultant desired actual value for the next weighing, which is held in a sample-and-hold module 36, and compared in a comparator 14 with the instant coke weight from follower 10 to develop on error signal which energizes a relay 16 controlling a conveyer belt, not shown, supplying the coke to a hopper. The calculating sequence is determined by a camtimer which is automatically started when the hopper begins to fill.
