Title: Process for waterproofing and lapidifying loose, porous or sandy strata
IPC: E02D3/12
Filed: 1934-01-19
Abstract: 415,326. Proofing and solidifying loose strata. FRANCOIS CEMENTATION CO., Ltd., 701, Salisbury House, London Wall, London.-(Assignees of Travaux Souterrains; 36<bis>, Avenue de l'Opera, Paris.) Jan. 19, 1934, No. 1972. Convention date, June 3, 1933. [Class 68 (i).] A process for waterproofing or lapidifying loose or sandy strata consists of injecting chemicals into the ground as the sinking of injection tubes proceeds and in concentrating the solutions as the pressure of injection tends to fall or diluting them as the pressure rises, i.e. concentrating or diluting as the permeability increases or decreases. In Fig. 1, boring tubes 1, 1<a> are driven by engines 2, 2<a> operating by rotation or percussion or both and are connected through distributers 5, 5<a> to pumps 7, 7a, driven by engine 8 which, with engines 2, 2<a>, receives motive fluid from pipe 4. The inlets of the pumps 7, 7<a> are connected respectively to mixers 9, 9<a>, receiving water under pressure from pipe 15 and also receiving respectively from tanks 10, 10<a> concentrated solutions of the reacting chemicals, e.g. sodium silicate and calcium chloride ; float valves 12, 12<a>, 16, 16<a> maintain constant heads in the tanks and mixers. One pump, preferably that delivering the more viscous solution, is connected through pipe 18 to regulators 19, 19<a>, which may comprise spring-pressed pistons and control cocks 20, 20<a>, whereby as the pressure increases the supply of concentrated solution is reduced. The boring and injection may be continuous, or periods of rest and injection may alternate. With a series of boreholes, holes 1, 4, 7.&c. are first treated, and intermediate pairs 2, 3 and 5, 6, the order of introduction of the solutions being reversed in these pairs. In Fig. 2, the two solutions are forced alternately through each boring tube under control of valves 31-34, the valves preferably being reversed after a given advance of the boring tubes. In a modification, the solutions are pre-mixed so as to form a latent precipitate which separates out within the ground. Further, when the ground contains one reagent, a single solution is injected.

Abstract: 265,198. Soc. Anon. des Etablissements J. et C. Mommers. Jan. 26, 1926, [Convention date]. Mules. - In an arrangement for stopping the rotation of the spindles for a period during the commencement of the outward run a double drive is provided from the countershaft to the rim shaft, one belt controlling the drawing-out of the carriage and the driving of the rollers and the other belt controlling the driving of the tin roller. The belts are independently movable. The countershaft A, Fig. 1, carries two pulleys with belts 1, G. The belt 1 engages fast and loose pulleys 19, 18 on a sleeve 20 loose on the rim shaft O and carrying a pinion 21 to operate the drawing-out of the carriage and the rollers. The belt is controlled by a counter-weighted lever 5 pivoted to the headstock and operated by a rockshaft 7. The belt G engages the usual fast and loose pulleys G<1> fast on the rim shaft and is controlled by a lever E on a rock-shaft D. At the end of the outward run an additional cam on the cam shaft engages a finger on the rockshaft 7 and transfers the belt 1 on to the loose pulley 18. A shaft D, Fig. 4, extending the length of the run carries overlapping and adjustable plates 25, 26 which are engaged by a bowl on the support H carrying the lever E near the commencement of the outward run, thus transferring the belt G on to the loose pulley and stopping the spindles for a predetermined period. As soon as the bowl leaves the plates the belt moves back on to the fast pulley and the spindles are again driven. The plates 25, 26 can be lowered so that the roller shall not engage with them and the mule be operated without stoppage of the spindles. In order to provide for the stoppage of the mule at the end of the inward run the stop rod K, Fig. 6, carries a member 33 which presses forward a rod 34 to engage and hold the arm 9 on the rock-shaft 7 to. maintain the belt 1 on the loose pulley 18. When the rod K is pulled to restart the mule the rod 34 is withdrawn by the spring 37 and the lever 5 is rocked back by its counterweight 11. The lever 5 carries an adjustable rod 17 adapted to engage the lever E and prevent the belt G moving back on to the fast pulley until the belt 1 is moved back on to the fast pulley 19.

Abstract: 849,144. Enrobing machines. JAHN, R. C. March 25, 1959 [Jan. 24, 1958], No. 2532/58. Class 28(1). In a chocolate enrobing machine which includes an enrober tank, the viscosity of chocolate in the tank is controlled by feeding tempered chocolate continuously to the tank at a predetermined rate in excess of that at which it is removed from the tank for the coating of articles, so as to ensure a controlled rate of overflow from a predetermined level within the tank. The overflow may be returned directly to a tempering installation or may be collected in receptacles for subsequent retempering. As described, chocolate is drawn from storage tank 1 through a valve 2 by a pump 3 and is delivered to an automatic batch tempering kettle 4 and thence to a holding kettle 5. The fluid tempered chocolate is pumped from kettle 5 to enrober tank 8 which has an overflow pipe 9 through which surplus chocolate is pumped back to storage tank 1 by a pump 10. Alternatively, the overflow may pass into an overflow pipe by way of a lip in the tank or a channel extending round the tank or it may be collected in receptacles from pipe 9 for subsequent retempering without the use of pump 10 and storage tank 1. The enrober tank 8 is deliberately fed with surplus chocolate under control of a valve 11.

Abstract: 1,070,662. Caps for collapsible tubes. N. NEUNER. Jan. 20, 1965 [Jan. 22, 1964], No. 2552/65. Heading B8T. [Also in Division F2] A closure for a collapsible tube container has a circular edge on a neck opening forming a valve seat 2a on which rests a valve head 11 retained in the closed position by spring arms 12 engaging the inner wall of the neck 2, so that by squeezing the container the valve head is lifted by the pressure of the tube contents from the seat. The inner wall 16 of the neck 2 is downwardly divergent so that the spring arms 12, which are connected to the valve head 11 by a stem 14, may be easily inserted into the neck where they abut against a shoulder 15. A conical seat portion 11a on the valve head 11 seats on the valve seat 2a, thereby sealing the neck opening. A synthetic plastics cap 3 screws on to the neck 2 and a flange 18 on the cap snaps over a flange 17 on the neck into a groove 19 which is downwardly divergent so that the base of the flange 18 forms a tight seal with the bottom of the groove. A conical wall 3a on the interior of the cap orifice bears on a corresponding conical wall 11b on the valve head 11 and pulls the valve head tightly down on its seat 2a. The contents of the container may be discharged by unscrewing the cap 3 through an angle less than 360 degrees, whereupon, on squeezing the container, the pressure of the contents on the spring arms 12 pushes the valve upwards and the contents extrude through the neck opening in the form of a tube, shaped by the wall 11b of the valve head 11 and a cylindrical upper wall 3b of the cap orifice.

[Class 141] [Also in Group XX] A method of manufacturing clothing includes the steps of taking a photograph of the person to be apparelled in a stationary position, and also of one or more objects of known dimensions, to form simultaneously on a single film at least two reflected images of said object or objects to the same scale as viewed frorr convenient angles and subsequently making an article of clothing from measurements taken from the photograph thus obtained. Apparatus comprises a pair of mirrors, guide means for positioning the person at least one object of predetermined dimensions, and a camera for simultaneously photographing the reflections in the mirrors of the person at the guide means and of the object adjacent thereto. As shown, a camera 1 and a light source 2, which may be a bulb repeatedly providing light flashes, are supported on a table 3 at one end of a booth. The person to be photographed stands on supports 10, 11 at an angle of about 45 degrees to the camera axis, and vertical posts 12, 13 of known dimensions or bearing calibration marks are placed behind and at one side of him respectively. Mirrors 14, 15 form front and side view images respectively. of the person, which are photographed simultaneously. The distances of the images from the camera are arranged to be the same, so that photographic front and side view images of the same size and a larger rear quarter-view image are simultaneously recorded. Images of the posts 12, 13 also appear in the photograph, and are used to compute tailors' measurements. Preferably a transparency is made, and projected from the rear on to a translucent screen to form a life-size image which is measured directly from the front. The three-quarter view image aids the estimation of given measurements. The person may wear measuring tapes or a harness or near-fitting garments of known measurements. A second photograph in which the person faces the opposite direction may be taken. Specification 407,202 is referred to.
