Title: Fluid flow control valves
IPC: F16K31/08
Filed: 1962-09-03
Abstract: 951,177. Valves. G. KROMSCHRODER A.G. Sept. 3, 1962 [Sept. 4, 1961], No. 33694/62. Heading F2V. A magnetically actuated valve comprises a valve closure 3, Fig. 1, having a stem 4 whose outer end carries an armature 8 movable in a sleeve 1<SP>1</SP> of non-magnetic material. A permanent magnetic 18, carried by a push-button 15, surrounds the sleeve and is loaded by a spring 19. To open the valve, the button 15 is pressed until the magnetic force between the parts 8 and 18 overcome a valve loading spring 5. On releasing the button, the stem rises with the magnet 18 until the armature engages a stop 13 at which position the magnet is held by attraction against the spring 19 as shown in Fig. 2. To close the valve, the button is pulled upwards and the spring 5 overcomes the force of attraction to close the valve and the parts again assume the position shown in Fig. 1. In a modification the armature 8 is replaced by a permanent magnet, the poles of the two magnets being arranged that with the magnet 18 in its upper and lower positions, repulsive forces hold the valve closed and open respectively. This arrangement avoids the use of any spring loading. In a further modification the arrangement of Figs. 1 and 2 can be used as an alternative manual actuation of an electro-magnetically actuated valve in which the sleeve is surrounded by a coil and the stem 4 is an armature separated from the armature 8 by a portion of non-magnetic material.

Title: Improvements in or relating to expansion valves
IPC: G05D16/06
Filed: 1932-11-28
Abstract: 390,777. Fluid-actuated valves. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ, 12, Place des Etats- Unis, Montrouge, Seine, France. Nov. 28, 1932, No. 33696. Convention date, Feb. 10. [Class 135.] A diaphragm-actuated pressure regulator is fitted with a supplementary cock in the inlet adapted to be closed in the event of the diaphragm being perforated or in the event of the pressure on the outlet side rising unduly. The main valve c which is balanced against high pressure by a diaphragm n is coupled by a spring k to a spindle q in turn connected to a diaphragm m loaded by weights r. An annular chamber b disposed above the diaphragm has a lower porous wall l and an upper wall formed by a flexible diaphragm so that in the event of gas permeating to the chamber the diaphragm is distended by osmotic pressure to release a pivoted catch normally engaging an arm g to maintain a cock e in the open position against the action of a spring h. In the event of the main diaphragm being abnormally distended, the spring k is compressed and an extension on the spindle q releases the catch. A strainer f is disposed in the inlet.

As described the voltages are measured by detector diodes 11, 13, Fig. 4, rectifying positive and negative half cycles respectively. The rectified signals are applied to amplifiers 43 and 44 having a gain set by resistors 51, 52 and a unity gain respectively, the outputs of the amplifiers being summed through resistors 53, 54 to provide a signal which after comparison with a reference level is used to control the gain of amplifier 12.

Title: Improvements in and relating to the starting of internal combustion engines
IPC: F01L13/00
Filed: 1921-12-16
Abstract: 179,508. Junkers, H. May 2, 1921, [Convention date]. Starting; stopping; reversing. - In an engine in which liquid fuel is supplied to the cylinders at the end of the compression stroke by a pump, a starting-air valve is actuated from the fuelpump, the valve being coupled to and uncoupled from the pump plunger 5 by means of a handoperated coupling-member 21 controlled by a lever 30. In the form shown, the pump plunger 5 is actuated from a cam 2 through a lever 3. The air-valve 17 is normally closed by a spring and the member 21 is mounted upon a pivot 25 adjusted by the control lever 30 pivoted at 26. The arm 22 of the member 21 embraces the plunger 5 between collars 6, 7, and the arm 23 embraces the valve-stem 18 between a collar 19 and a fixed abutment 20. At starting, the lever 30 is moved upwards, bringing the member 21 into contact with the collars 6, 19, so that the air-valve 17 is opened and is actuated from the cam 2. The engine is stopped by lowering the lever 30 into a position in which the member 21 engages the collars 7, 20 and holds the plunger 5 away from the cam 2. In this position, the lever 30 may be rocked to actuate the pump 5 by hand in order to fill the fuel-supply pipes before starting. For reversing, the fuel-supply pump is stopped by means of the lever 30, and the cam shaft 1 is moved axially. In a modification, the member 21 is replaced by a single-armed lever pivotally connected to the pump plunger, and connected to the valve-stem 18 by a pin and slot and to a lever such as 30 by a link.

Abstract: 501,089. Coke-oven bracings. OTTO & CO., GES., DR. C. Dec. 9, 1937, No. 34085. Convention date, Dec. 18, 1936. [Class 51 (ii)] Outward bowing of the buckstays of a cokeoven battery is prevented or controlled by truss members, each comprising an horizontal beam 19 pivoted at its outer end to a vertical support 20, and tied to the lower end of the buckstay. The beam rests at its inner end on a ledge 21 and the tie consists of tension rods 22, 23, 24 linked by a connector 25, the rod 24 having a turnbuckle adjustment 34. The beams 19 are formed by pairs of back-to-back channel irons, and are used to support the working platform. In a modified construction the beam 19 is rigidly secured to the buckstay by an upright member extending for some distance along the buckstay below the oven floor level, and in this case the tensioning device is omitted.

Title: Warp knitting machine
IPC: D04B27/08
Filed: 1964-08-21
Abstract: The trick plate of a Raschel machine Figs. 2, 3, 6 (not shown) is mounted so as to be capable of moving in a direction opposite to that of the needles whereby the needle movement is reduced and the speed of knitting increased.  For this purpose the trick plate 65 is mounted on an arm 66 adapted to be oscillated by cams 69, 70 in timed relation to the movement of the needles which are controlled by a similar arm 51 operated by cams 47, 47a. Alternatively the needles may be operated by two eccentrics 48, 49 through linkage 73 ... 78 and the trick plate may be similarly controlled.  The rise and fall of the needles and plate may be such that at the trick plate may be lowered with the needles at the end of the needle lowering movement to provide a dwell period during which the stitches are drawn and knocked over.  The fabric take down rollers may be mounted on the trick plate arm 66 to ensure a constant distance between the rollers and verge edge or a resilient tensioning arm may be provided to impinge on the fabric and maintain a constant tension in the fabric despite the movement of the trick plate.

Tempering. - Steel or alloy objects, such as rails, susceptible to tempering by immersion in a liquid are subjected whilst at a temperature above the critical point to a series of immersions of short duration in a limited quantity of cold or hot liquid, which is proportional to the size cf the objects. The rail f is carried by rollers c which are suspended by brackets b from the horizontal supporting beam a below which is arranged a small tank d containing the cooling liquid. Fastening bolts e disposed along the beam prevent deformation of the rail during tempering. To effect the immersions the beam may be stationary and the tank movable vertically, or the tank may be stationary and the beam given an alternate vertical movement, or both the beam and the tank may be stationary and successive variations produced in the level of the liquid.

In a joint for a conveyer or driving belt of rubber or the like having longitudinal reinforcing wires cut in steps to abut endwise, two adjacent wires with blind ends are adjacent one or more rows of abutting wires coming from different directions, one wire from one direction overlapping another wire from the other direction. The wires may deviate from their longitudinal direction within the belt to produce substantially equal gaps between adjacent wires and the abutments may be within or without the overlap of the joint and may be transverse to the belt, staggered or sloping. Examples are given of different configurations of the wires according to the invention. The joint may be made by baring the wire ends, securing them in the desired position on a rubber base with adhesive, causing the joint with another rubber plate and curing the joint.
