Title: Improvements relating to pumps
IPC: F04B9/04
Filed: 1932-07-21
Abstract: 389,717. Pumps. CHALMERS, R. A. and TECALEMIT, Ltd., Great West Road, Brentford, Middlesex. July 21, 1932, No. 20657. [Class 102 (i).] In pumps comprising a number of independent pumping units each having a separate inlet and outlet and the units being arranged to be operated in pairs by the use of pivoted rockers oscillated about their pivots by eccentrics or like means, the effective stroke of each piston can be regulated from the exterior of the pump casing. A shaft 6 carries a rocker arm 8 with lower jaws 16 embracing a cam member 17 on a driving shaft 7. The ends 12 of the rocker engage with blocks 13 and screwed into these blocks are rods 23 the lower ends of which have a ball-joint connection 22 with the plungers 21. These plungers are reciprocated in cylinders 20 contained in the main casing 1 there being an inlet direct from the tank in which the pumps are immersed and an outlet at 19 for each unit. Whereas the actual stroke of the plunger 21 is fixed, its effective stroke can be varied by alternating its mean position in the cylinder. This is effected by means of an exterior knob 34 which rotates a block 26 having slots 30 with which ears on the rod 23 may engage. The outer end 24 of the rod 23 is free to slide in an axial opening 25 in the adjusting screw. A number of such transverse pairs may be arranged on the common shaft of the casing 1 which may have an additional filter alongside it.

Title: Improvements in or relating to electromechanical oscillators
IPC: H03H9/54
Filed: 1964-05-20
Abstract: 1,073,963. Electromechanical oscillators. SIEMENS A.G. May 20, 1964 [May 21, 1963], No. 20713/64. Heading H3U. An electromechanical resonator is divided into sections by two or more piezo-electric elements so located as to excite one or more even harmonics and suppress the fundamental and odd harmonics, or to excite the funda. mental and one or more odd harmonics and suppress the even harmonics; the piezoelectric elements are each composed of two plates, one on each side of the neutral axis of the resonator and have their planes perpendicular to the longitudinal axis of the resonator so as to excite bending oscillations therein; the piezo-electric elements are located at stress nodes of the harmonics to be suppressed, or are arranged so that the stresses cancel out at harmonics to be suppressed. The construction of the resonator and the attachment of the piezo-electric elements thereto is the same as in Specification 1,073,964. In Fig. 7 two pairs of piezo-electric crystals 15, 17 are located equi-distant from the centre and are oppositely polarized, so that stresses at the even harmonic frequencies cancel out. If the crystals are at nodes of the third harmonic this also will be supprossed, leaving only the fundamental, fifth and higher odd harmonics. By changing the direction of polarization in one 'pair of elements (Fig. 8, not shown) the fundamental, and odd harmonics will be suppressed, and by locating the elements at the nodes of the fourth harmonic only the second, sixth and higher even harmonics will be excited. By adding two further pairs of crystals to the arrangement of Fig. 7 (Fig. 13, not shown) the fifth harmonic will also be suppressed. Modifications of Fig. 7 which produce the same result are (a) one pair of crystals at the centre and one pair at the node of the third harmonic, the two pairs being mutually oppositely polarized (Fig. 12, not shown), and (b) each crystal being replaced by a pair of oppositely polarized crystals with a conductive layer between them (Fig. 10, not shown).

Title: Improvements in or relating to safety switching devices
IPC: B60L3/02
Filed: 1926-08-23
Abstract: 281,005. Forbes, G. Aug. 23, 1926. Controllers, handles. - The power and brakes of an electric train &c. are controlled by a switch requiring continuous or intermittent motion on the part of the motorman, as distinct from the exertion of a continuous pressure on the dead handle. The device may replace the usual dead handle or may be used in conjunction therewith. In the form shown in Fig. 1, a knob 8 on the dead handle 1 is rotarily oscillated by the operator to oscillate a disc 51 to which is secured a Bowden cable 52. The other end of the cable is secured to a spring-urged piston working in a cylinder filled with oil or other fluid and connected to a second cylinder. A piston in the second cylinder is connected by a Bowden cable 63 to the pawl 44 holding the cam 39 in the power-on position. Omission on the part of the operator to oscillate the knob results in the tripping of the pawl 44 after an interval determined by the oil cylinders, which comprise a time-lag device. In the form shown in Fig. 11, the knob 8 is vertically reciprocated by the operator to drive a centrifugal governor 83 through the archimedean screw 86 and gearing 84, 85. Failure to maintain the requisite speed results in a circuit being made at contacts 90 to energize a coil 80 to trip the pawl 44. Other modifications are described, including one in which the 'centrifugal governor of Fig. 11 is replaced by an electro-thermally operated relay.

Title: Improvements in wireless telegraphy
IPC: G01S1/02
Filed: 1920-07-17
Abstract: 151,253. Trost, S. O. E. T. July 18, 1919, [Convention date]. Directive wireless signalling; aerials; wireless aeronautic signals. - Apparatus particularly adapted for aircraft is arranged to determine the direction of propagation or reception of electromagnetic waves in three dimensions. As shown in Fig. 1, three loop aerials a, b, c are set up in planes mutually at right-angles, and are connected by three leads, including series condensers h, i, k, to three circular coils d, e, f mutually at right-angles, each lead being connected to a pair of coils. The direction of arriving waves is determined by adjusting the position of a movable coil g until maximum reception is obtained. If the coil g is connected to an oscillation-generator, radiation will be a maximum in a direction determined by the position of the coil. In a modification shown in Figs. 2, 3 and 4, four wires of equal length l m n o are suspended so that their outer ends lie at the apices of a regulator tetrahedron, and their inner ends near its centre. In addition, the apices may be joined by other conductors shown in dotted lines. The inner ends of the wires l m n o are connected to the four corners of a regular tetrahedron whose edges are conductive and at whose centre is mounted a search coil g. In practice, the field influencing the coil 9 is increased by connecting in each of the wires near its mid point a coil of one or more turn, such as Fig. 3, the coil being tangential to the wire and in a plane containing it and at right angles to the opposite wire. A system of six coils is thus obtained, and they are proportioned, as shown in Fig. 4, so that each lies on a great circle of the sphere to which the sides of the tetrahedron are tangents.

Filed: 1921-08-15
Abstract: 188,756. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). Aug. 15, 1921. Work supports.-Relates to machines of the kind adapted to insert a series of fastenings step by step into a boot or shoe or part thereof, and characterized by having a clutch, the opposite conditions of which respectively determine continued operation or inoperativeness of the machine, and a work support moved by power between its operative and inoperative positions ; and consists in power operated means for bringing the work support to operative position and throwing in the clutch to enable these machines to be operated with less exertion. As shown, a starting treadle 324, Fig. 4, when depressed, raises a rod 328 turning a bell-crank lever 338 on a shaft 340 also carrying an arm 342, Fig. 5, arranged to actuate a latch 370. A slide 362 is continuously reciprocated by a cam roll 360, and on the first ascent of this slide after the depression of the treadle a shoulder 378 on the slide engages the latch 370 and lifts a slide 366, the slide being retained in its raised position by a latch 380 engaging a shoulder 382 until this latch is withdrawn by release of the treadle. As the slide 366 rises a geared segment 386 moves a lever 388 connected by a link 392, Fig. 4, to a lever 394 turning a cam 416 which lifts a lever 404 raising the work support 36. The rise of the slide 366 also raises a rod 466, Fig. 3, turning a lever 510 pulling on a link 506 on a lever 494 pivoted to one member of a toggle 478,480 between the clutch withdrawing lever 482 and a pivoted arm 470 carrying a cam roll engaging a cam surface 474 on the cam shaft of the machine. The breaking of the toggle allows engagement of the clutch, and the machine, operates until the treadle 324 is allowed to rise. When this occurs the latch 380 releases the slide 366 which falls as far as is allowed by a latch 522, Fig. 3, engaging a shoulder 524 on the rod 466 and straightens the toggle 478, 480. At the end of the machine's cycle the cam 472 operates the straightened toggle to withdraw the clutch and stop the machine. As the clutch lever is moved a projection thereon releases the latch 522 to allow the rod 466 and work support to descend. The slight lowering of the work support between fastening insertions to allow of work feed is effected by a rod 424, Fig. 9, reciprocated by a cam on the main shaft and operating a bell-crank lever 332 operating a link 436 alternately breaking and straightening toggle members 400, 440, Figs. 4 and 9, the upper member of the toggle being pivoted to a slide 442 depressed by a powerful spring. The slide 442 is held in position when the toggle is broken by pawls 450 released as the toggle is straightened by a stop 458 carried by the link 436. An auxiliary treadle 580, Fig. 4, is provided to raise the slide 366 manually when desired. Specification 8772/09 is referred to.
