Title: Improvements in plug cocks
IPC: B67D1/07
Filed: 1935-11-27
Abstract: 466,425. Plug cocks. LOFMARK, G. B. Nov. 27, 1935, No. 32895. [Class 135] The tapered plug of a plug cock is held in a tightening position by a spring 41, Figs. 1 and 3, secured to the body of the cock at one end and engaging with the plug at the other end. This engagement is effected by means of a bayonet slot 42 in the end of the spring which in a certain position of the plug passes on being depressed over a pin 39 projecting radially from the stem 38 at the small end of the plug. The plug is then turned until a radial projection 45 at the large end of the plug enters into a recess 44 in the cock body which limits the normal operative movement of the plug between shoulders 43 under which conditions the spring 41 is always in engagement to keep the plug in position. The plug is readily removed for cleaning by slight axial movement and rotation beyond its normal limiting position until the spring 41 disengages from the pin 39 when the plug can be removed. The invention is shown in Figs. 10 and 11 applied to a three-way cock for liquid dispensing apparatus, peripheral passages 159-161 on the plug being adapted to provide communication between passages 156 and 157 in one position and passages 123 and 157 in another position, these positions being determined by a radial projection 171 against stops 172, 173 respectively. A third position in which the passages are closed is determined by a spring-catch 166 engaging projections 168, 170 on the plug body. The knob 164 must be released and depressed respectively to enable the catch 166 to pass these projections to move the plug from one extreme position to the other.

Abstract: 537,660. Heels and top-lifts, attaching. UNITED SHOE MACHINERY CORPORATION. Dec. 28, 1939, No. 32939. Convention date, Dec. 29, 1938. [Class 17 (i)] A machine for attaching heels and toplifts has a jack for inside heelattaching, a turret with a plurality of fastener inserting devices for top-lift attaching and alternative clamps for securing the work when a heel or a top-lift is to be secured. The machine is operated manually. The jack 22 for inside heel - attaching has drivers 30 inclined inwardly and downwardly at their ends to tip the nails inwardly. The drivers are retained in their correct angular positions by a polygonal plate 34 engaging slots in the drivers. The driving plunger is urged downwardly by a spring 36, and raised for nail-driving by a member 186 carried on an arm 174 raised by a treadle. A rotatable turret carries a number of independent nail inserting means t for attaching top-pieces to heels after these have been attached to the shoe. Each comprises a casing 60 bored to house the nails to be driven, which nails normally rest on drivers 76 urged downwardly by a spring 82 and raised by a plunger 188 co-operating with a plunger 196 backed by a spring 194 the tension of which can be adjusted. The spring is supported by a casing carried by an arm 176 moving with the arm 174. The heads of a pair of pins p engage the heel to facilitate the positioning of the same. The work is clamped to either nail inserting device by means carried by arms 104, 106, either being swung'to the front as desired. The heel clamp comprises a plunger 108 urged upwardly by a spring and held in its downward clamping position by a pawl 114. Guide ways 120 carry a slide 122 supporting a self-adjusting heel tread face abutment 130 and a pad 138 on a shank 136 for engaging the rear of the heel. The shank and slide bind when pressure is applied to the heel. The other clamp has a serrated plate for engaging the insole of the shoe. A spring plunger 107, releasably retains the selected clamp at the front of the machine. As the head is turned to adapt the machine from heel attaching to top piece attaching or vice versa a link 182 reverses the member carrying the plungers 186, 196, to move angularly to an idle position that plunger not required. When the machine is being used for top piece attaching the fall of the plunger 196 and treadle is limited by the insertion of a spring-urged stop 202 below the arm 176 carrying this plunger. The stop is moved to out-of-the way position by the link 182 when the machine is again set for heel attaching. U.S.A. Specification 2,135,656 is referred to.

Abstract: 806,458. Magnetic storage devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 21, 1955 [Nov. 23, 1954], No. 33238/55. Class 38 (2). [Also in Group XXXIX] A data storage device comprises a magnetic body such as ring 1 bearing a signal input winding 2 and an output winding 3, the body being stressed mechanically to vary the magnetic flux and develop an output signal in winding 3 indicative of the prevailing remanence state of the body. The stored information is thus read out in a non-destructive manner. The magnetic material is preferably a ferrite having low crystalline shape and stress anisotropy and a high magnetostriction constant, e.g. a nickel zinc or cobalt zinc ferrite. The stress is applied by piezoelectric action of a ceramic ring 6 of material such as BaTiO 3  bonded to the outside of the ferrite ring 1 by application of a pulse or train of pulses of voltage to electrodes 7 on the faces of ring 6. Alternatively the pulses may be applied radially between electrodes on the inner and outer surfaces of the piezoelectric ring, Fig. 4 (not shown). In further modifications the stress may be applied axially to magnetic ring 1. The ring is clamped between members 12, 12 with a piezoelectric ring across which voltage is applied, Fig. 5 (not shown), or another magnetic ring 13 carrying a winding 14, Fig. 6. Current through winding 14 produces stress by magnetostriction of ring 13.
