Filed: 1916-10-03
Abstract: 110,006. Constantinesco, G., and Haddon, W. Oct. 3, 1916 Hydraulic transmission of power.- Relates to generators for producing a series of periodic changes of pressure and volume in liquid columns such as described in Specification 9029/13, and has for its object the production of waves and liquid currents of high frequency. A generator, according to the invention, has a cam or rotor h, so shaped that for one revolution several pulsations are imparted to a number of light pistons f having a very short stroke. The pistons are inclined, as shown, to the waved surface of the cam or rotor h so that the pistons are uniformly rotated about their axes. Oil is pumped into the groove k for cooling and lubricating. The space l containing the liquid acted upon by the pistons has a part m projecting into it. In a modification, the pistons are parallel to the main shaft and the curved camsurfaces are placed on the lateral faces of a ring.

Abstract: 542,055. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 12, 1940, No. 14125. Convention date, Sept. 12, 1939. [Class 38 (v) ] [Also in Group XIII] In a thermostatically-controlled iron as described in Specification 523,047, bi-metallic strip 10, e.g. of " Invar " (Registered Trade Mark) and steel, is secured to a plate 11 which is screwed to the sole plate 23, and the free end of the strip carries an actuating member 18 for the flexible contact arm 17.

Title: Improvements in liquid level indicating devices
IPC: G01F23/16
Filed: 1931-05-13
Abstract: 375,033. Indicating liquid levels. PIONEER INSTRUMENT CO., Inc., 754, Lexington Avenue, Brooklyn, New York, U.S.A. May 13, 1931, No. 14143. Convention date, May 16, 1930. [Class 123 (i).] In a remote liquid level indicator operating under atmospheric pressure for reservoirs such as the fuel tanks of aircraft, a venting device constituting a single unit (influenced by the static and dynamic pressures) is provided for venting at a common point the reservoir and the indicating device. The indicator 11 consists of a casing 12 having a flexible chamber 13 which is responsive to pressures transmitted to it from a fuel tank 14 by means of a hydrostatic cell 15 and a pipe 16. The chamber 13 operates a pointer 17 moving over a dial 23 through a link 18, and a pivoted rack 19 meshing with a pinion 21 fast on the shaft 22 on which the pointer is mounted. The dial 23 has a celluloid or other transparent cover 23a carried by a frame 23b. An air pump 25 is provided for clearing the tube 16 of liquid to give correct indication of the liquid level. To equalize pressure in the indicator 12 and in the tank 14, a common venting means 33 is provided consisting of a coupling member 40 having passages 41, 42. A tube 34 attached to or integral with member 40 carries a perforated sphere 35 divided by a partition 36 into portions 37, 38 one of which communicates with passage 41 and the other through pipe 47 with passage 42. The chamber 31a of the indicator 11 is connected to passage 42 and thence to the atmosphere by a tube 32 which is screwed to a union 45 screwed into the passage. The member 40 is screwed into the top of the tank 14 which thereby is in communication with the atmosphere through a check valve and passage 41. The check valve consists of a ball 49 secured in a chamber 50 by a perforated washer 51, Fig. 5, the central portion of which is concave, forming a seating for the ball. If the tank is inverted, the ball falls against the entrance 53 of passage 51 and prevents escape of the fuel.

Title: Improvements in or relating to devices for controlling the welding times and intervals in resistance welding apparatus
IPC: B23K11/24
Filed: 1954-05-14
Abstract: 758,971. Control systems for resistance welding. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 14, 1954 [May 18, 1953], No. 14193/54. Class 38 (4). A circuit for generating across a resistor 24 voltage pulses for controlling the lengths of the " on " and " off " periods of a resistance welding machine comprises a thyratron relaxation oscillator 1, 3, 6 generating pulses having an interval between them equal to the sum of the two periods, a second similar oscillator 13, 15, 17, for determining the ratio of the two periods, subject to control both by the pulses of the first oscillator (applied over pulse transformer 7) and by mains frequency pulses (injected by transformer 27), and a trigger circuit controlled by the second oscillator over pulse transformer 16 and comprising thyratrons 18, 19, the anode circuit of 19 of which includes the resistor 24 which also forms part of the grid circuit of the second oscillator and so controls the standing D.C. bias on its thyratron 13 according as to whether or not thyratron 19 is conducting. The arrangement is such that the discharge in thyratrons 18, 19 switches from one tube to the other each time the second oscillator pulses transformer 16 and the magnitude of the mains frequency pulses supplied by transformer 27 is such that they are unable to trip tube 13 when tube 19 is conducting and resistor 24 providing hold-off bias. Tube 13 is, however, tripped by the larger amplitude pulse supplied by transformer 7, whereupon tube 19 becomes non- conducting, the bias on tube 13 is removed and that tube then comes under the control of transformer 27. Tube 13 thus fires alternately under the control of transformer 7 and transformer 27.

Abstract: 292,337. Exton, W. G. May 30, 1927. Photometric apparatus; colours, comparing.-Apparatus for measuring the turbidity, colour and other characteristics of fluids comprises two fields of view, one being a field illuminated by a beam of light traversing the absorbent fluid under test and the other a comparison field illuminated from the same source without traversing the fluid. The two fields are examined simultaneously by the same eyepiece. A source of illumination is arranged in a housing 8 provided with a wall 2 having an aperture 38 fitted with a shutter 39 for direct illumination of fluid contained in the receptacle 32, and also with an aperture 21 arranged so that a beam may be directed from the reflector 20 axially through the fluid in the receptacle 32. This second beam also traverses a transparent rod 31 which is adjustable in an axial direction and then passes by way of prism 60 to the eyepiece 62. The direct comparison beam is reflected from the mirror 73 passing to the eyepiece by way of prisms 71, 80 and 68. Means are provided for adjusting the position of the rod 31 and of indicating the same on the exterior of the apparatus, and rack and pinion gear is fitted to operate the shutter 39. Wedge plates for measuring turbidity or transparency are inserted in the guides 50 and actuated by rack and pinion gear by the rod 54. Colour filters may be similarly fitted in the guides 56 for colour testing. When using the wedge filters a target plate x is mounted in the frame 11 beneath the receptacle 32 and the wedges are moved until the plate x is obscured. A Nicol prism 66 is fitted in the path of the rays from the test fluid to the eyepiece and is rotated by the handle 67. Similar polarizing and analysing prisms 75, 76 are fitted in the path of the direct beam before reaching the Lummer-Brodhun cube 68. The rotation of the plant of polarization of the fluid may thus be also determined. Guides 83, 84 are fitted as shown for absorption wedges in the direct beam. Colour filters may also be fitted as caps to the eyepiece 62. Several kinds of test are described in connection with diagrams, such as Fig. 5, of the arrangement of the apparatus for carrying out the particularly kind of test.

Abstract: 1,046,823. Lens caps and hoods. PAILLARD, S.A. April 6, 1965 [April 29, 1964], No. 14549/65. Heading G2A. A member 1 having two side walls 5 and a transverse wall 4 is pivotally attached to a camera objective so that it acts in one position as a cap (Fig. 2, not shown), and in a second position (Fig. 1) as a partial lens hood or "sunshade". As shown, the housing 2 of the objective is of square section. On each of its outer faces it has a recess 9 opening into a deeper recess 10. In recess 10 moves a slider 11 having raised end bosses 13. A screw 14, attached to the centre of slider 11, extends through a slot 18 in side wall 5. A spring 16, pivoted at 17 to the objective housing, engages against the lower of the bosses 13, always tending to urge the slider downwards. Thus the member 1 is spring-urged firmly against the front of the housing in the "cap" position of Fig. 2, or firmly against the top surface 7 of the housing in the "shade" position (Fig. 1). In this latter position, it is prevented from rearward movement by a pin 19. This pin can be retracted into the housing, allowing member 1 to be slidden backwards when a shade is not required.
