Title: Improvements in or relating to valves
IPC: F16K5/22
Filed: 1928-04-11
Abstract: 298,052. Nordstrom, S. J. April 11, 1928. Channels and reservoirs in valves.-The lubricant chamber 17, into which the small end of a tapered plug valve 4 of known type projects, is nearly filled with powdered mica. The remaining space is filled in the usual way with lubricant inserted in an axial reservoir 20 in the plug stem and, by screwing in a stop plug 21, forced through radial passages 19 and surface channels 18. The mica reduces the amount of lubricant employed in the first packing of the valve and enables other lubricant to be substituted therefor, if necessary, by displacement without disassembly. Being under compression, the mica assists in forcing the lubricant between the walls of the plug and casing when the valve is operated. A washer 9 bears on the upper end 7 of the plug, a superposed ring 10 of packing material being compressed thereon by a cover plate 11, a projection 13 on which engages a recess 14 in the stem to limit rotation to 90‹.

Title: Multi-signal device for automotive vehicles
IPC: B60Q1/50
Filed: 1957-04-02
Abstract: 815,351. Road traffic signals on vehicles. ZGRAGGEN, W. M. April 2, 1957, No. 10770/57. Class 118 (2). [Also in Group XXXVII] A signalling apparatus for signalling to drivers of vehicles behind the vehicle equipped with the apparatus comprises a control panel mounted near the driver's seat and an indicator visible to the rear. The control panel (Fig. 2) may comprise a set of push buttons 24, any one of which, when pressed, causes a corresponding visible indication, and a " blank " button which cancels the indication. The indicator, shown in horizontal section in Fig. 7, includes a hexagonal drum 45 on five sides of which are pairs of markings each corresponding to those on the pushbuttons. One of each pair is on the upper half of the drum wall and the other on the lower. The sixth side of the drum is blank. The drum is rotatable about shaft 43 along which it can also be moved axially so that any selected marking may be positioned opposite window 48 in the rear wall of the casing 40. In order to rotate the drum a solenoid 58 is energized and its core operates bell crank 52 through link 55 and causes rack 50 to move and rotate pinion 49 on the drum shaft 43. The correct positioning of the drum is determined by stops cooperating with a step on rack 50 at positions corresponding to the presentation of each of the marked faces. The stop 65 furthest out is fixed the remaining stops 61, 62, 63, 64 are controlled by electromagnets. A vertical electromagnet 69 operating a linkage 66 may be energized to lift the drum vertically to display the lower indication on the selected face. When a selected pressbutton 24 is depressed against the pressure of spring 31 rod 28 closes the required number of circuit contacts 33 and the flange 32 of the button passes beneath spring-loaded latch 35 so that the button is held down and the circuits maintained closed. For any particular button 24 the contacts energize solenoid 56 and one of the electromagnets controlling stops 61, 62, 63 and 64 if required. If the indication is the lower one of a pair electromagnet 69 is also energized. When the " blank " button is depressed solenoid 36 is operated to draw back latch 35 and release whichever button 24 has been depressed. The energizing circuits are broken and spring 59 causes the drum to rotate to its at rest position with the blank face visible. The indication presented at the window 48 may be illuminated.

Title: Production of closed bottom shells
IPC: B21D22/28
Filed: 1976-03-17
Abstract: 1531075 Automatic control AMERICAN CAN CO 17 March 1976 [17 March 1975] 10802/76 Heading G3N [Also in Division B3] Can bodies are formed in a press having two spaced forming stations, dies at each station on a common horizontal axis, means for feeding blanks alternately to the stations, a horizontal doubleended punch 33, Fig. 13, for drawing the blanks through the dies, and feedback means for monitoring the position of the punch and for constantly adjusting force applied to the punch so as to move it through the dies at substantially constant velocity. The press is controlled by a logic system 300, Fig. 15, embodying event-set-point switches and responsive to external sensors and feedback monitoring of the punch and two blank feeders, the eventset-point switches delivering signals to respective memory units 320, 302, 335. The feedback means for the punch is a stationary transformer 220 the core 222 of which is attached to the punch so that a voltage analog is produced which is delivered to summing amplifier 321 which feeds punch position information back to the logic control. The logic control operates a servo valve which positions a main valve for supplying hydraulic fluid to a piston for moving the punch. A similar arrangement controls the feeders. Operation of units for stripping formed blanks from the punch and for discharging them from the press are also controlled by the logic. Failure to attain a programmed position results in the main valves being centred in a null position. Event set-set-point switching is also used at times appropriate for cup feeder fully extended, cup in position, punch fully extended, and shell being stripped.

Abstract: 785,447. Railway track brakes. DISTINGTON ENGINEERING CO., Ltd. June 3,1955 [April 14, 1954], No. 11003/54. Class 103 (1). In a railborne vehicle, the body carries one or more brake shoes mounted for vertical movement relative to the body and spring biased downwards and the body is supported on fluid pressure actuated means mounted on the wheel axles such that when the fluid pressure is released from said means, the body will be allowed to fall under gravity thus bringing the brake shoe or shoes into frictional engagement with the rail to brake the vehicle. In the embodiment illustrated, the rectangular underframe 1 of a railborne vehicle is supported on four fluid pressure operated cylinder assemblies 2 mounted on axles 3 and 4. Hydraulic pressure is distributed by means of a combined pump and liquid storage tank 23 to supply each of the cylinder assemblies 2. As soon as the pressure is released, the weight of the underframe, body and contents of the vehicle causes the brake shoes 15 to frictionally engage the rail and brake the vehicle. Each brake shoe is provided with a shock-absorbing spring 18 and the vehicle may be provided with known means, for releasing the pressure in the sytem when the speed exceeds a predetermined value. Specifications 285,966, [Class 103 (i)], and 514,256 are referred to.
