Title: Improvements in or relating to variable electric condensers
IPC: H01G5/38
Filed: 1922-12-04
Abstract: 210,577. Pfeiffer, A. F. Dec. 4, 1922. Switches; contacts.-A variable condenser is provided with switching means for connecting it in series or in parallel with an inductance or other apparatus according to the direction in which the movable vanes or electrodes are rotated from the position of minimum capacity. In one arrangement, Fig. 4, an insulating arm 1 secured to the end of the spindle S carrying the movable vanes V<@> engages a pair of contact arms 2 which are adapted to move over studs C<1> - - C<@>. The external circuit is connected to terminals T', T' and the apparatus to be connected in series or parallel with the condenser is connected to terminals T<2>, T<3>. In the position of minimum capacity shown, the terminal T' is directly connected to the terminal T<2> and the condenser is short-circuited. Movement of the arm 1 in the clockwise direction connects the condenser across the terminals T<2>, T<3> in parallel with the apparatus connected to these terminals; movement in the opposite direction connects it across the terminals T<2>, T<3>. In a modification, Fig. 9, a radial arm 3 secured to the spindle S engages an insulating arm 1 carrying contact brushes 4, 5 of the shape shown. In another modification, Fig. 13, an arm 1 mounted on the spindle carries contact brushes 2, 3 which move over contact tracks 4 - - 6. In any of these arrangements, the connections may be such that the condenser is left in series or parallel with the apparatus connected to the terminals T<2>, T<3> in the position of minimum capacity. In another construction, Fig. 17, the desired connections are effected through contact springs 8, 9 co-operating with fixed contacts 10, 12, the contact springs being provided with insulating projections 6, 7, which engage a cam 1 carried by the spindle S. In a modification, the cam operates, either directly, or through an intermediate lever, a sliding member carrying a pair of contact blades.

Abstract: 325,283. Hart, R. P. Nov. 17, 1928. Collisions, lessening effect of.-With the object of lessening the possibility of telescoping of railway carriages in a collision, the body is mounted on the undercarriage so as automatically to be swung to an angle by the shock, the plates or other means which hold the body and undercarriage in normal relation being broken under the stress. In the arrangement shown the carriage body A is provided on its under surface with a pair of projecting blocks a of steel or other metal which abut against corresponding blocks b on the under-carriage. As shown, the effect of a collision will be to swivel the body A in a clock-wise direction, the movement being arrested by extensions c<1>, c<2> of the blocks b which extensions offer increasing resistance as the displacement becomes larger and may act in association with the vehicle brakes. To facilitate the turning movement the ends d1, d<2> of the body A are preferably inclined.

Title: Apparatus for the dosing of liquids
IPC: C02F1/68

Abstract: 632,117. Apparatus for dosing liquids. HENRIKSEN, M. P. Dec. 22, 1947, No. 33806. Convention date, Aug. 30, 1946. [Class 86] Apparatus for dosing measured quantities of liquids, such as lime-milk into boiler feed water, is provided with a siphon for each liquid, all the siphons automatically operating to feed the liquids when one of them is started. A tank 1 for boiler feed water is provided with a bell siphon 4, 5 which operates at a given level of water in the tank. The pipe 5 is formed into a U-shaped trap 6 provided with an overflow weir. An air line consisting of tubes 7, 8, 9 interconnected by tube 23 is provided to ensure correct metering of the water flow, the tube 7 extending almost to the bottom of the tank 1 and being provided there with a cup 12 apertured at 13, the tube 8 entering the top of the bell 4 and the tube 9 being of U- shape to form a water trap 10 inside the trap 6. The traps 10, 6 are filled with water when the operation cycle begins. and as the water level in tank 1 rises, fed from a main 2, air pressure in the air line clears trap 10. When the level of water in tank 1 reaches the required level siphon 4, 5 operates, and water is again drawn into trap 10. The siphon operates until the water level reaches the bottom of tube 7, when air is admitted to the siphon and its operation is stopped. The water main 2 is then opened by a ball operated tap 3. Connected to the tank 1 is a bell 14, a tube 15 leading from the top of the bell to a siphon pipe 16 in a lime-milk container. As the water level in tank 1 falls, air is drawn into the bell 14 from the siphon 16 and this is started to operate. A cut out tube 21 adjustable by means of a scale 24 allows air to enter the bell 14 and hence stops the action of the siphon 16 when sufficient lime-milk has been fed. The air line 15 is branched at 22 and 25 to enter the siphon tube 16 at two points to obtain satisfactory metering.

Title: Improvements in or relating to finishing operations upon boots or shoes
IPC: A43D95/06
Filed: 1929-11-13
Abstract: <PICT:0343077/III/1> Coating machines.--The sole edges are guided against a rotary absorbent or flexible tool such as the felt wheel 22 which is continuously supplied with molten wax from a contacting rotary member such as the metal wheel 24.  Means are provided for regulating the pressure between the wheels &c. 22, 24.  As shown in plan in Fig. 2, the wheels 22, 24 are driven in contact with each other at equal peripheral speeds by belting and pulleys 20, 18.  The shaft 16 of the wheel 22 is carried in a bracket 26 pivoted on a vertical axis 28.  A spring plunger 32 tends to separate the wheels, but they are kept in contact and the pressure between them is regulated by a screw 30.  A circular plate 40 on the wheel 24 overlaps the felt wheel 22 and keeps the edge square. The felt wheel is simply pressed on the end of the shaft and on a driving pin and may be changed by swinging the shaft until the wheel is clear of the disc 44.  Reservoirs 52 for different waxes are adjustable about the vertical axis 50 so that the spout of any reservoir may be brought above the wheel 24.  The reservoirs may be heated electrically, the metal wheel 24 by a gas-jet 34, and the felt wheel 22 by contact with a metal flange 36 on the hub 38 heated by a jet 42.  The flow of wax from the reservoirs may be regulated by screws 55 at the nozzles, but exact adjustment is not necessary and the supply from the nozzles may be intermittent as the periphery of the wheel 24 carries a substantial quantity of molten wax, heaped up in waves, and spiral grooves may also be provided.  Shoe-guiding means are shown at 70 and 62, either of which may be swung aside whilst the other is in use. For work with thick soles having perpendicular edges, the sole face is held against a button 62 on a sliding spring-urged rod 63 controlled by a foot-pedal in accordance with the width of the edge to be waxed.  For work with thin soles having bevelled edges the feather crease is held against the edge of an inclined disc 70 free to rotate and mounted on an adjustable arm 72.  Shaft couplings.--The shaft 38, Fig. 3, carrying the heated flange 36 is connected with the driving shaft 16 only by set screws 41 to minimize conduction of heat.  Securing sleeves on shafts.--A sleeve 73 carrying the arm 72 is adjustable about the shaft 74, Figs. 2 and 4, by means of a screw 76.  The end of the screw bears against one face of a recess 79 in the shaft, contact being maintained by a torsion spring 77. Specifications 5355/05 and 14696/08, [both in Class 17, Boots &c.] are referred to.
