Title: Improvements in liquid level indicators for fuel tanks of internal combustion engines
IPC: G01F23/16
Filed: 1929-01-14
Abstract: 327,474. Parr, G. W. Jan. 14, 1929. Elastic-diaphragm pressure gauges.-An automatic liquid fuel gauge for internal-combustion engines comprises a dip pipe 16 extending to the bottom of the tank 7 and connected with a pump 2, supplying air to overcome the head of pressure in the pipe, and a manometer 6 with an impervious flexible diaphragm 9 displacing indicating fluid in the tube 11. The diaphragm is of corrugated metal and extends across a casing 8. A similar diaphragm 13 is provided in the tube 11 above the indicating fluid. If the tank is under atmospheric pressure, the outer side of the diaphragm 13 is open to the air, but it is connected with the top of the tank if the fuel is under pressure. Air is supplied by a pump comprising a spring-loaded piston connected with the engine induction pipe. '

Title: By-Pass Valve
IPC: F16K41/04
Filed: 1967-01-10
Abstract: 1,175,742. Valves. SHUNT AB VARMETEKNIK. 10 Jan., 1967 [31 March, 1966], No. 1297/67. Heading F2V. A valve, adapted for use as a mixing and control valve in water heating systems, comprises a valve body 1 having three or four connecting sockets 2 (of which only two are shown), and conical valve seats 11 and 12 against which abut conical flanges 61 and 62 respectively, of a slide 6. Between the flanges 61 and 62, the slide comprises a flared part 63 and two radial slide vanes 64 (of which only one is shown), the outline of which vanes 64 corresponds to that between the flanges 61 and 62 as is shown in dotted lines. The extensions of these lines intersect to make an angle " a " which is equal for both the slide and its seat and has a valve between 30 and 90 degrees, preferably 65 degrees, the exact value being chosen to be larger than the angle which would permit the slide to be fastened to its seat for given slide and seat materials. A rotatable stem, fixed to the slide, passes through the neck 7 of a cover 3 and has disposed around it, and in between the neck and slide, a compression spring 8 which thrusts the slide against its seat, the cover 3 being secured to the valve body 1 by bolts 4. Substantially cylindrical interspaces 16 and 36 are provided to allow the slide, in the event of expansion or wear, sufficient freedom of movement along its axis. Rotation of the slide, and thus the vanes 64, provides the desired communication between the various sockets 2, while additional vanes (65, 66, Fig. 2, not shown) designed to cause turbulence, enhance the mixing and/or control of fluids flowing into and out of the valve.

Title: Improvements in revolving magnetic clutches, particularly for x-ray time switches
IPC: G04F3/06
Filed: 1943-01-26
Abstract: 567,708. Friction clutches. CALDWELL, T. F. Jan. 26, 1943, Nos. 1324 and 18565. [Class 80 (ii)] [Also in Group XXXVII] An electric time-switch operating device, particularly for X-ray apparatus, comprises a switch-actuating arm 41 fixed to one part 30 of a two-part armature 18, 30. The part 30 is freely supported on a pin 29, and the part 18, which is mounted on a fixed pin 25, is continuously rotated by an electric motor through a gear 28. The armature is surrounded by an electric coil 8 carried by a U-shaped bobbin 7 which is held in a two - part housing 5, 6. When the coil 8 is de-energized, the parts 18, 30 of the armature are held apart by a spring 34, and the angular position of the arm 41 may be set to the desired position. Upon energizing the coil 8, the armature part 30 is attracted towards, and is gripped frictionally by, the armature part 18 so that the two parts revolve together. The switch is thus actuated after a predetermined angular movement of the switch-actuating arm 41. As shown, the arm 41 is bifurcated, and is secured to the armature part 30 by a friction grip. The part 18 comprises three radial arms 21, each forming a magnet pole 22, each of which has a rectangular copper band 59 to prevent hum and vibration. The face of the part 30 adjacent to the poles 22 may be ribbed to keep the contacting faces clean and to prevent sticking. Frictional material may be arranged between the parts 18, 30. In a modification, both parts 18, 30 are of annular ring form.

Items of information punched on a tape, Fig. 3, are each associated with a single perforation D1, D2 &c., and pulses derived from the sensing of these perforations are used to step an electronic distributer, Fig. 4, to distribute successive items of information to different registers 16, 18, 20. Each item of information may be a command for a machine tool. Perforations D2, D4, D6 are associated with X, Y, Z dimension commands. Columns 2-7 of the tape correspond to decimal denominations, and a digit is recorded in each column by punching the appropriate number of perforations. Thus the X dimension shown has the value 11À 8125. The distributer has its discharge stepped on to a different cathode in response to each pulse from perforations D1, D2 &c. and enables a corresponding row of six vacuum tube AND gates having their other inputs connected to receive pulses from columns 2-7 of the tape. The output from each gate is supplied to a corresponding stage of the associated register 16, 18, 20, each stage comprising a multicathode counting-tube similar to the distributer. Other commands such as direction, feed rate, spindle selection may be recorded in single rows of the tape associated with perforations D1, D3, D5 etc.

Abstract: 563,302. Etching. ODHAMS (WATFORD), Ltd., and VERRIOUR, S. J. Feb. 4, 1943, No. 1901. [Class 100 (ii)] A method of making wire gauze or perforated metal sheets consists in applying an acid resist to a metal sheet by coating the sheet with a light-sensitive material, e.g. bichromated colloid, exposing it to light through a screen comprising closely spaced opaque dots on a transparent background and washing away the unexposed colloid, viz., that covered by the dots of the screen, and etching through the metal between the lines of the resist. The lines of the pattern may be criss-cross sets of parallel lines or may be arranged to form any desired geometrical or irregular shaped orifices. In a modification, a sheet of paper with a light-sensitive coating, such as a gelatine coated carbon tissue, is exposed under the screen and the sheet then applied with its coated side to the metal sheet, after which the sheet and the unexposed parts of the colloid are removed. The metal sheet may be formed as an electrolytically deposited film on a smooth metal cylinder, from which, after it is converted into a perforated sheet, it is removed and opened out into sheet form.
