Title: Improvements in or relating to soil-testing apparatus
IPC: E02D1/02
Filed: 1950-05-09
Abstract: 681,626. Testing physical qualities of materials. COMPAGNIE INTERNATIONALE DES PIEUX ARMES FRANKIGNOUL SOC. ANON. May 9, 1950 [June 16, 1949], No. 11500/50. Class 106 (ii). Soil-testing apparatus having a pointed member which is driven into the soil by a rod guided in an outer sheath, a seal between the lower ends of the rod and the sheath, and means for measuring the resistance encountered in driving the point and the sheath, is characterized in that it comprises a piston adapted to transmit the driving force to the rod and mounted in a hydraulic cylinder adapted to transmit the driving force to the sheath, and means for measuring the pressure effective in the said cylinder and corresponding to the force applied to said piston, the cylinder itself being submitted to a hydraulic pressure which is in turn measured to give the total driving force. The driving force is applied by a screw 23, to the head 22 of the rod 20 of a piston 4 working in a cylinder formed in a body 1. The space below the piston is filled with oil and is connected to a pressure-gauge 6 which indicates the total pressure applied to the sheath and the tip. A second piston 5 also works in a cylinder formed in the body 1 and its rod 12 acts on the rod 13 carrying the tip 14. The space above this piston is connected to a pressure-gauge 7 which indicates the pressure applied to the tip alone. The pistons have packing seals 8, 9 retained by plates 10, 11. Secured to the body 1 is a conical guide 15 which abuts the sheath 16 surrounding the rod 13. The lower end of the sheath carries a ring 19 or is formed with a groove which holds a packing 18 against a sleeve 17 integral with the tip 14. The sleeve 17 tapers upwardly and the diameter of the main part of the sheath 16 is equal to the greatest diameter of the tip 14. The resistance of the sheath is thus due only to lateral friction against the soil. The whole apparatus is suitably supported, the piston-rod 20 having a portion of square section guided in a yoke 24, itself guided for vertical movement in the support. The rod 13 and sheath 16 are made in sections, additional sections being screwed on as the driving proceeds. To withdraw the rod and sheath, the body 1 is first raised slightly and then an annular member 27 is placed around the sheath, a ring 28 being screwed above it to the sheath, and a screw 29 being engaged in the end of the rod so as to overlap the ring 28. Links 30 pivoted in the member 22 have pins which are engaged on brackets 33 on the body 1 so that when the latter is raised, the sheath and rod are also raised. In a modification, each section of the rod 13 has an enlarged lower end which is engaged, when the sheath is raised, by a shoulder at the upper end of the next lower section of the sheath.

IPC: F23D11/18
Filed: 1922-04-25
Abstract: 203,363. Castellazzi, V. April 25, 1922. Spray burners. - Liquid such as naphtha is atomized by steam generated in a vaporizing member heated by the burner flame, the steam flow being regulated by a cock mounted on the burner and arranged between the vaporizing member and the burner nozzle. In the apparatus shown diagrammatically in Fig. 1, a reservoir divided by a partition into fuel and water compartments F, W is subjected to air or gas pressure produced by a pump P. The water passes from the compartment W through a pipe D to a, vaporizing coil A and the steam produced passes through a regulating cock B to the burner and atomizes oil supplied from the compartment F. Shut-off cocks G, E are provided in the water and oil supply pipes. The combustion of the fuel may be started by means of an air jet. Alternatively, separate fuel and water vessels connected by a pipe so as to be subjected to the same air pressure may be used or one vessel may be arranged within the other. Figs. 2 and 4 show the preferred form of burner. The fuel enters the burner through an inlet 7 and passes to a mixing- chamber 26 through a cock 17 and an annular cone-shaped outlet 18 in a tangentially arranged nozzle 19. Water entering the burner through an inlet 5 is vaporized and superheated in a helical passage 20 leading to an annular end space 22 which is connected by a passage 23 to the rear of the burner. The steam then passes through a cock 24 and the inner conical opening 25 of the nozzle 19) to the mixing chamber 2& in which it atomizes the fuel for combustion in the burner. Reference has been directed by the Comptroller to Specifications 6619/88 and 12998/88.

Title: Recording apparatus for the measurement of distance by the echo-sounding method
IPC: G01S1/72
Filed: 1939-04-17
Abstract: 527,737. Recording-apparatus. DOMIN, P. A. April 17, 1939, No. 11639. [Class 106 (iv)] [Also in Group XXXVIII] In a recording device for echo-sounders, a waxed strip a runs over a drum b which is rotated synchronously with the echo soundings and carries a helical recording edge c. The arrival of the echo causes the release (electrically) of a member d which is then pressed by a spring on to the recording edge so marking the recording strip at a point g whose distance from a zero line determines the depth sounded. In a modification, the recording edge has the form of an Archimedean spiral situated on a revolving disc, the member d now lying along a radius. Instead of the above arrangement, the recording edge may be made to press down upon the wax paper. The member d may be replaced by electrical contacts and a spark made to pass between one of these and the recording edge when the echo is received. Or again, the recording edge may be made to conduct heat which melts the wax when contact is made.

Abstract: 333,886. Rogers, F. H., (Johnson- Stephens & Shinkle Shoe Co.). April 15, 1929. Connecting uppers to insoles and soles.- The edges of a lasted upper are pressed against the face or edge of an insole by holding devices while the lasting tacks are extracted, and an outer sole is then laid on and temporarily secured thereto, as by lasting tacks, while the upper is still held shaped to the last and under the lasting tension. The holding means are then withdrawn and the parts permanently connected together, as by stitching or adhesive. The temporary fastening means are then withdrawn. In the form shown in Fig. 3, the upper is lasted over the insole in the usual manner and secured by lasting tacks, the heel and toe being permanently secured by tacks 5, 6. Holding means 7, having fingers 9 spaced apart, are then applied at the forepart and remain in position while the lasting tacks are withdrawn and while an outer sole 8 is temoprarily secured at the forepart, as bv tacks 3. Similar holding means but narrower and with smaller spaces between the fingers are then applied at the shank and the outer sole is secured there also. These two sets of holding means mav be mounted on the same machine or different machines of similar character and both .operations may be performed successively or simultaneously. After the sole has been secured to the upper and insole by the tacks 10, the holding means are released, the shoe removed and the sole secured permanently, as by through stitching. The tacks 10 are then withdrawn. If a channel flap is provided, this may be stuck down and stitched also, if desired. An alternative form of holding means for the upper adapted to clamp it against the edge of the insole is shown in Fig. 8, and comprises elements 71 faced with rubber 14 or other material. If desired, holding devices may be provided to hold the upper around the entire shoe. When adhesive is employed for the attachment of the sole, an inflated pad is used to press the sole against the upper and insole.

Title: Improvements in or relating to fuel regulators for internal combustion engines
IPC: F02M21/00
Filed: 1962-03-27
Abstract: 940,995. Spray carburetters. OHLSSON & RICE Inc. March 27, 1962 [May 8, 1961], No. 11661/62. Heading F1B. The pressure of fuel supplied to a fuel nozzle 23 is maintained constant by a spring-loaded pressure regulator valve 29 in the fuel supply passage 10 which is controlled through a lever 44 by a diaphragm 42 in a chamber 30 downstream of the valve, the lever being loaded by a spring 60 which bears upon the lever fulcrum 48. The fuel flows through chamber 30 to passages 31, 32, leading to the nozzle 23, the passage 32 being restricted by a needle 34. The lever 44 is pivoted on a bush 47 surrounding a fulcrum pin 48 and the valve 29 is urged closed by a U-shaped leaf spring 60 which engages at one end on the lever arm 53, is pivoted on the under side of the bush 47, and engages at the other end on a rollable stop 63. The opposed forces of the lever and spring on the bush 47 are approximately equal so that the bush turns with minimum friction on the pin 48. The weights of the ball 29 and lever arm 44 are also arranged so that on inversion of the carburetter the effects of gravity on the valve 29 are counterbalanced. An increase in suction in chamber 30, e.g. due to sudden opening of the throttle valve 13, causes diaphragm 42 to open valve 29 so that the increased fuel flow to chamber 30 restores the former to the predetermined value.

Abstract: 794,203. Automatic frequency control. SPERRY GYROSCOPE CO., Ltd. April 16, 1956 [April 22,1955], no. 11681/55. Class 38 (4). In an apparatus for controlling the frequency of a non-salient-pole type generator the rotor of which is driven approximately at the correct speed corresponding to the desired frequency, the stator winding is energized in accordance with the difference between the actual speed and the desirable speed to produce a field rotating at a speed equal to the difference and in a sense such that the rotor and stator fields have a relative rotational speed, equal to the desired speed. The output frequency of an auxiliary generator 5 on the main generator shaft is modulated with the three-phase reference frequency in unit 6, and the modulator output is amplified and applied to stator winding 2 of the main generator 1. In alternative arrangements described with reference to Figs. 2 and 3 (not shown), the reference voltage is applied to the stator windings through commutators on the generator shaft. In the former, three commutators, one for each phase, each comprise two 180 degree segments and the field circuit includes filters to select the difference frequency, and in the latter a multi-segment commutator has its segments connected to circumferentially-spaced points on a delta winding fed with the reference frequency. In a final alternative, a delta winding fed with the threephase reference voltage is connected to the segments of a fixed commutator and brushes mounted on the generator shaft take off a supply to the stator field.

Title: Improvements in printing presses
IPC: B41F1/28
Filed: 1921-03-22
Abstract: 182,257. Woodbury, J. E. March 22, 1921. Platen presses.- A device for feeding sheets to a die printing or other press is constructed with h s h e e t - forwarding means from which the sheet is taken by a reciprocating carriage having a supporting device for the front edge of the sheet, the rear edge of the sheet being allowed to drop between this support and the forwarding means. The sheets are fed by a separating device B, of known kind, and by a roller 25 rotated intermittently by a rack 23 operated by a crank on a shaft 18, driven by sprocket gearing from the main shaft 13 which is itself operated by sprocket mechanism from the press. The feed devices are mounted in a frame having brackets which rest on dowels carried by the press. From the roller 25 the sheets are forwarded by rollers 28, 31, and tapes 29, across adjustable slats 35, which extend beyond the tapes and support the sheets as they are forwarded by a reciprocating carriage 80, formed with grippers operated by toggle mechan ism to press the sheets against supports 86 on the carriages. The sheets are registered by front stops 39 and movable side registers 60 which are each oscillated about vertical pivots 59. The sheets are forwarded to an intaglio die-printing press A by the carriage 80, which is reciprocated on guides 81 by an oscillating frame 77 operated by a pair of links 74 and a cam 71 on a lever 69. The lever 69 is oscillated by a reciprocating rod 63 con nected to a crank 62 on the shaft 13, a spring 67 being interposed between the rod 63 and lever 69. When the carriage 80 is in its left hand posi tion, as shown in Fig. 2, a lever 90 on it, which is provided with a gripper 93, is actuated by toggle levers 91 to close on the sheet and grip it to the carriage. The toggle levers are operated by can and lever mechanism from the shaft 18, this mechanism comprising an oscillating arm 100 which operates a rod 102 connected to a spring- controlled arm 103 on the shaft 87 of one of the toggle levers. As the carriage 80 moves to the right and brings the sheet into printing position, the rear edge of the sheet passes down between the slots 35 and the carriage, and the carriage moves so as to bring notches 112 into contact with pins 111 on a frame 110, which is raised by a cam 106 and lever mechanism so as to pivot the carriage about its rear supports and to move the sheet up against the counter-die a' just before the die a is raised to effect the printing operation. This movement prevents smudging of the paper. The rear edge of the paper is taken after the impression by gripper mechanism and delivered as in Specification 182,170.
