Filed: 1972-04-21
Abstract: 1349813 Lawn mowers MASON & PORTER Ltd 21 April 1972 [6 July 1971] 18618/72 Heading A1F The cutting height of a power driven lawn mower is adjusted by a manually operable lever linkage interconnecting the front and rear ground wheels without obstructing the grass cuttings discharge chute 3 in the mower's housing 2. In one embodiment (Fig. 1) each front wheel 6 is mounted on a stub axle 8 at one apex of a triangular plate 7 whose lowest apex is rigidly connected to its counterpart by a transverse rod 30 pivotally mounted in the front of the housing. The other apex of one of the plates 7 is connected by a rod 9 to a crank 29 linked to a transverse rod 16 interconnecting the mountings of the two rear wheels. Each mounting comprises an oblique 'T-shaped' member 10 which has a stub axle 13 for the respective ground wheel and is rotatably mounted via aperture 12 and sleeve 28 to the housing 2. The cutting height is altered by a lever 17 riveted to one of the members 10 and having a detent 18 which engages a range of apertures 19 in an associated plate 20, adjustably secured by bolts 23 to the housing. To facilitate height adjustment the mower's weight acting on lever 17 is counterbalanced by a spring 24 which is connected at one end to the housing and at the other to either the associated member 10 or to the transverse rod 16 (not shown). The geometry of the linkage is such that each interval in the range of apertured settings 19 produces a small increment in height when the cutter is near the ground and a larger increment at more elevated levels, and may be such that either the housing 2 remains horizontal throughout the various settings and slopes forwardly at some of the settings. In alternative embodiments the T-shaped members 10 may be replaced by triangular elements and the pivot point 28 may be raised with respect to the wheel axle.

Abstract: 335,239. Bardsley, H. June 18, 1929. Induction pipes, fittings for.-A valve device for admitting air for braking and cleansing to a vehicle engine comprises a spring-loaded cylindrical slide g axially movable, under the control of the driver, in a casting a having flanges e, f by which the device is fitted between the carburettor and induction manifold. A through passage h normally passes carburetted air to the engine but when the slide is raised to the position shown in Fig. 5 the passage leading from the carburettor is closed and the induction pipe is opened to the atmosphere through a passage i, j. A slot i<1> provides for a limited supply of air as the slide is first moved towards the air admission position. Rotation of the slide is prevented by a set screw in the wall of the casting a which engages with a groove in the slide. In a modified construction, the passage h is omitted from the slide, the lower end of the casting a being closed so that on raising the slide the mixture passes directly through the casting; when the slide contacts with the closed end of the casting the passage i registers with the transverse opening on the engine side of the casting. Anticushioning holes are provided to permit the movement of the disc into the closed end of the casting. According to the Provisional Specification the slide may be of stepped form, having felt washers at each step to prevent leakage when in the normal running position.

Title: Improvements in variable resistance networks for phase shifting apparatus
IPC: B23K11/24
Filed: 1959-06-02
Abstract: 913,992. Resistance networks. WELTRONIE CO. June 2, 1959 [Nov. 28, 1958], No. 18773/59. Class 40 (8).  A variable resistance for use in conjunction with a non-linear device comprises a switch for increasing the resistance in different increments to obtain equal decrements of current and a fine adjustment for obtaining subdecrements, the magnitude of the sub-decrements being arranged to vary in accordance with the value of the next decrement to be selected. As shown, resistors 101R to 108R have values (generally unequal) calculated in accordance with the curvilinear law of the load to change the value of the current between terminals 52, 54 by equal decrements of 10% as contact 60 is moved by switch ISW from one tapping point to the next. In addition, by means of switch 2SW, any number of a set of ten smaller resistors 117R to 126R may be connected in series with the resistors of the coarse setting to obtain nominal current decrements of 1%. The maximum value (in current decrements) of the fine setting should amount to 10% at each position of the coarsesetting contact 60. The required variation in this value over the whole range is obtained by shunting the selected fine resistors 117R to 126R with the next succeeding one of the selected coarse resistors. This is done by means of movable contact 62 forming part of the coarse-setting switch 15W. For example, if contact 60 is set at the third position to include resistors 101R and 102R in circuit, resistor 103R is placed in parallel with the selected number of fine resistors 117R to 126R which each provide, under these conditions, a 1 % current decrement. In the embodiment, resistors 101R to 108R are made greater than their nominal values and are shunted by corresponding numbers of the set of resistors 109R to 116R selected by contact 66 of switch 1SW. The 10% decrements of current thus result from the parallel combinations of resistors selected by contacts 60 and 66. The variable resistance is incorporated in a resistive branch for one phase of a polyphase phase-shifting network whose other phases have resistive branches with similar variable resistances. The phase-shifting circuits may be those described in Specification 913,991, where they are applied to a welding controller.

Title: Improvements in mercury button electric switches
IPC: H01H29/04
Filed: 1959-06-02
Abstract: 906,602. Mercury switches. GENERAL ELECTRIC CO. June 2, 1959 [June 2, 1958], No. 18798/59. Class 38 (5). A mercury button switch comprises a cylindrical metal shell 11 forming one terminal and welded to an annular metal ring 22 carrying an insulating window 21 and a second terminal 20, the whole enclosure being hermetically sealed. A tubular ceramic liner 25 with a partition 26 is fitted rigidly in the shell 11 and has an opening 27 to connect the mercury pools 29, 30, and a cavity 28 formed in one side of the liner and located so that in the " ON " position of the switch the lower cavity edge is in line with the top of the mercury and the centre of the opening 27 and liner 25, and in the " OFF " position the lower edge is below the mercury surface, Fig. 7 (not shown). This arrangement increases the kinetic energy of the pool 29 at the instant of circuit opening or closure, thus reducing arcing, and the use of a mixture of hydrogen and argon gas at 1.7 atmospheres is of further assistance in this respect. A silicone rubber washer 43 prevents leakage of mercury to the metal ring 22 and is screened from the arc by a ring 44 on the liner 25. A small spot of silver paint on one side of the partition 26, Fig. 5 (not shown), provides an anchor point for the adjacent mercury pool, and friction between the mercury and the surrounding enclosures is reduced by roughening the ceramic and metal parts. Specification 462,527 is referred to.
