Abstract: 348,227. Shears. WULFF, K., (trading as HOWALDT, F., [Firm of]), 25, Kirchhofallee, Kiel, Germany. Feb. 17, 1930, No. 5307. Convention date, Aug. 8, 1929. Addition to 256,728, [Class 30, Cutlery]. [Class 30.] The shears described in the parent Specification, in which a straight knifeedged blade beds against an abutment blade and the pivot is offset from the blade line, is modified to enable it to cut battens or wood strips on the mitre. For this purpose, an inclined guide or guides is formed integrally with or attached to the abutment blade- and the batten is placed thereagainst. The cutting blade 2, Figs. 1a and 1b, moves perpendicularly to the place of the paper and guides 5 are secured on each side of the abutment blade 4 carried by the handle 3. As shown in Fig. 2, the guide 5 is adjustable and is secured in position by a pin 8 engaging- any one of a number of holes in the abutment member 4. In a modification, Fig. 3, surfaces 10,11 are provided on the abutment member 3, 4 on opposite sides of the cutting blade 2 and at such different heights that the batten can be placed across them at the required angle. The surface 11 may be extended so as to provide a surface at right-angles to the plane of movement of the blades,. so that the batten may be cut at an angle of 90‹.

Hollow articles, e.g. balls, are obtained by injection moulding two halves thereof each having external flanges and which are then placed in a pair of cylindrical swages 1, 2 having cutting edges 3, 4, the swages being initially partially closed, Fig. 6, leaving a gap equal to the combined thickness of the flanges, which are then softened (Fig. 7, not shown), the swages then being closed (Fig. 8, not shown) to form a ball and removing the external flange e.g. by a device as in Figs. 10, 11 (not shown). In one embodiment (Figs. 1-3, not shown) the halves have both internal and external flanges of rectangular section which produces a ball (7, Fig. 3, not shown) having an internal reinforcing rib (10) and in another embodiment (Figs. 4-11, not shown), the internal flange may be eliminated by providing the halves 13 with a triangular external flange 14, Fig. 6. The edges may be softened by heat generated by application of ultrasonic waves, the passage of electric current through a resistance, rotating the halves oppo. sitely to heat by friction or by direct heat from a hot plate or knife or alternatively by heat directed by mirrors or by solvents or adhesives which will partially dissolve the edges of the two halves. The material of the article may be polyvinyl chloride.

Title: Improvements in Governing Mechanism for Turbo-generator Installations.
IPC: G05D13/00
Filed: 1918-07-08
Abstract: 124,203. British Westing- house Electric & Manufacturing Co., (Assignees of Hodgkinson, F.). July 10, 1017, [Convention date]. Motor power plant; regulating.- Relates to turbo-generator installations comprising high and low pressure sections 33, 34 driving separate electric generators connected to sections of a common bus-bar, the duplex low-pressure section being connected with the high-pressure section by a valved conduit 36, and having also a high-pressure supply pipe 41<a>, and consists in providing each turbine section with an automatic stop governor 72 of any usual type which, when a section exceeds a predetermined speed, operates through a relay 73 to close the valve 71 controlling the high-pressure steam supply to the section, and also operates an electrical relay 74 for opening the circuit-breakers between the generators and between the generator driven by said section and the bus-bar supplied thereby. The circuit-breakers may also be instantaneously opened by manually tripping the automatic stop governor, which is substantially similar to the trip mechanism shown in Fig. 4 This mechanism is used in con nexion with a governor 37<a> Fig. 3, which operates (a) to close the valve 38 in the pipe 36 when the section 34 exceeds a safe speed, and (b) to open and control a valve 41 in the pipe 41<a> to supply high-pressure steam to the section 34. Mounted on the governor lever 37<b> is a finger 47 adapted to release from a latch 46 a trip lever 45 and so allow a valve 44 to open and permit the space below a differential piston 60, Fig. 5, to be exhausted, this space being connected by a port 66 and a pipe 67, Fig. 1, with a valve 44. The piston 60 thereupon shifts a valve 52, admitting pressure fluid below a piston 49, which thereupon shuts the gate valve 38 mounted on the rod 50. By connecting the pipe 67 through a pipe 67<a> with the discharge pipe 67<b> controlled by the automatic stop governor 72 of the section 34, this governor not only closes the .stop valve 71 but also the valve 38; whereas by reason of the check valve 67d, the governor 37<a> only effects the closure of the valve 38.

Abstract: 682,444. Vacuum systems. WETHERILL ENGINEERING CO. Feb. 24, 1948 [Jan. 11, 1943], No. 5452/48. Class 8 (i). Control means for a vacuum system wherein the pressure is adjusted at a predetermined rate of change, having a vacuum source such as a pump, a chamber to be evacuated and a connecting line therebetween, comprises a valve 38 in a line 58, the valve being exposed on one side to atmospheric pressure through restricted opening 52 and on the other to the vacuum within the line 58. The valve, normally open at the commencement of a cycle of operation, is seated by means of a spring 40 compressed between the end of a valve rod 44 and a link 36, and opens when atmospheric pressure on the valve exceeds the compression of the spring. The spring pressure is set by means of nuts 42. The link 36 is pivoted to a beam 24 pivoted at one end at 26 and bearing on a cam 18 at the other. The cam 18 is rotated through gears 10, 14 by means of an electric motor 2, whereby the degree of compression of the spring 40 is varied at a predetermined rate, thereby controlling the pressure in the system in a similar manner. The characteristics may be varied by controlling the motor or substituting a different cam. A modified spring device is described where the spring is in tension. Specification 645,437, [Group XXII], is referred to.

Filed: 1920-02-26
Abstract: 154,109. Fairweather, H. G. C., (Svenska Turbinfabriks Aktiebolaget Ljungstrom). Feb. 26, 1920. Reversing; regulating. -A turbine is provided with forward and reverse gearing to which it may be coupled by clutches, and the speed governing devices are connected to the reversing-gear so that the speed of the turbine is reduced to half the normal speed before either clutch is moved. The governor A controls the throttle valve B through a hunting-gear 8, 23, 24, and the running speed is determined by the position of the normally fixed pivot 24. The parts are shown in the position when the turbine is running idle. When the reversing hand-wheel 39 is turned to couple the turbine through either the forward or reverse clutch, the final movement of the hand-wheel opens a valve 33 of a hunting-gear 27, 35, 33 controlling the position of the pivot 24, and that pivot is moved into a position determining a higher running speed for the turbine. The clutches are laminated friction clutches and are controlled by a piston 44 and a hunting-gear 47, 48. When the piston 44 is moved to put in the reversing-clutch, a piston 50 is moved to the right and admits oil from the pipe 51 to the clutch. All the hunting- gears are supplied with oil under pressure from a pump 10.
