Abstract: 488,326. Toothbrushes. LOWENSTEIN, R. June 12, 1937, No. 16381. [Class 19] A toothbrush comprises a tubular head 10, Fig. 1, of metal or other rigid material having one or more apertures 11 formed therein and a hollow casing 1 fitting over it with registering apertures 7 and bristles 6. The casing 1 is readily detachable from the head 10. The head 10 is attached at 8, 9 to a water supply.

Filed: 1921-06-14
Abstract: 186,114. White, A. E., (National Lead Co.). June 14, 1921. Solids, treating with liquids.-Apparatus suitable for the treatment of solids with liquids comprises a horizontal rotary cylinder 1 into which the solid is continuously fed from the inlet 12. Liquid is supplied to the cylinder in the first instance from tanks 36 located beneath it. As the cylinder rotates liquid from the tanks enters each of the receptacles 35 through a hole 37 (Fig. 5), the amount being controlled by an adjustable overflow pipa 88, and is finally discharged into the cylinder through the pipe 30. This pipe is permanently mounted on the cylinder wall, and terminates in a spray nozzle 31. To obviate caking of solid on the pipe and nozzle, the extent of inward projection of the pipe is made greater than the normal depth of the bed of solid, as shown in Fig. 2, and moreover the pipe 30 is air-jacketed by means of a surrounding pipe 32 A disc-valve 39 operated by a weighted lever 39<a> is so arranged that the pipe 30 is closed during the process of filling, and does not discharge. until the position indicated in Fig. 2 is reached. In this way the spray is made to impinge entirely upon the solid and not upon the cylinder wall. The nature or concentration of the reagents supplied to the tanks 36 may be varied. The apparatus is intended for use more particularly in the production of white lead.

Title: Improvements in or relating to direction finding radio receivers
IPC: G01S1/02
Filed: 1938-06-02
Abstract: 494,564. Directive wireless systems. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. June 2, 1938, No. 16597. Convention date, June 24, 1937. [Class 40 (v)] A direction-finding arrangement in which the pick-up from a continuously-rotated directional aerial deflects a synchronously-rotated optical device giving a luminous trace of the pick-up characteristic, is characterized by an improved optical system giving a more intense luminous trace. In Fig. 1 an image of the synchronouslyrotated slot diaphragm c which is illuminated by the light source a and lens b is focused on to the synchronously-rotated mirror e by the lens d to produce a line image on the screen f at right-angles to the radius. The intensity of the screen image is increased by contracting the line to a point by means of the synchronouslyrotated cylindrical lens g. If the mirror is deflected radially inwards by the rectified pick-up, the direction is indicated by a luminous pointer, Fig. 2. Excessive mirror deflections may be prevented by an amplitude limiter in the signal channel. With small signal pick-ups, the points of the luminous pointer corresponding to zero current will not be sharp and a clearer indication is obtained by applying the modulation frequency voltage to the mirror deflection means to produce a directional diagram as shown in Fig. 3. In order to produce a continuous indication a modulation frequency greater than the usual 1,000 cycles per second should be employed and this frequency should be of the order of the resonance frequency of the deflection system so as to produce large deflections.

Abstract: 592,215. Ignition systems. BENDIX AVIATION CORPORATION. Oct. 13, 1943, No. 16839. Convention date, March 3, 1942. [Class 7 (iv)] An ignition system particularly for an engine comprising a number of radially arranged, axial rows of cylinders 11 has a separate magneto 15 for each row of cylinders, each magneto being associated with a pair of distributors 27, 28 supplying through respective high tension leads 33, 34 dual ignition to oppositely-disposed sparkplugs 12, 13 in each cylinder. As shown, the engine is provided with seven rows each containing six cylinders. The seven magnetos which are of dual construction are mounted on pads 16 integral with the engine casing and each has a cam 24 controlling circuit breakers 22, 23, Fig. 3, in circuit respectively with primary _coils 20a, 21a associated with secondary coils 20b, 21b. These secondaries are connected respectively to a distributor 27.connected to a row of plugs 12 and a distributor 28 connected to the. plugs 13. The high tension leads extend through tubular metallic shields 35, 36 secured through a flexible section to the magneto casing and having flexible metallic branches 41 detachably connected to shielded spark plugs.' Free space in the distributor block housings and in the tubular shields is preferably filled with a yieldable insulating compound such as polymerized cashew nut-shell oil. Both primaries of all magnetos may be simultaneously earthed by means of leads 43, 44 extending into a circular metallic shielding tube 46, the lead connections to the magneto being of the plugand-socket type to facilitate assembly. The leads 43, 44 are connected through a multiple connector 47, 48 and tube 49 to a switch 50 by which either one or both sets of magneto primaries may be earthed so that in some cases an engine may be run on a single set of plugs 12 or 13. For starting, booster current may be supplied to the distributor 27 from a battery 57. The primary 53 of a buzzer coil is connected at one end to the battery by line 58, 59 and starter-operated switch 60. The other end of the primary coil is connected to switch 50 and is earthed only when this switches in one of its "on" positions. The secondary of the buzzer is connected to the distributor 27 by shielded leads 63, 62 having plug connections with fittings 65 connected by a line 66 to the distributor. Preferably for high altitude flying, the magnetos are charged with air or inert gas delivered by a pump 70 or by a pressure tank and passing through a filter and dryer to the magnetos through the earth wire conduits 45, 46. The' magneto casings may be rendered relatively gas-tight or each magneto may be enclosed in a separate gas-tight casing or hood.

A device for retaining valves in their sockets consists of an angle-section post 14 mounted with its trough facing away from the valve 12, and having guide bands 18 formed by cutting portions across the angle, and notches 17 at the top. A straight piece of wire 15A guided in the bands 18 has a horizontal loop 15B at its upper end to engage the pip 24 of the valve, the other end being bent horizontally into a stop 20. The post is attached to the chassis 13 by the socket-securing bolt 22. The device can be secured in several positions, depending on the height of the valve, by means of a catch 16 bent from the loop 15B being placed in any of the notches 17. The stop 20 is forced against the side of the angle of the post, thus preventing the catch 16 from slipping out of the notch.
