Title: Machine for testing pipes and the like by internal pressure
IPC: G01M3/28
Filed: 1950-11-30
Abstract: 729,034. Detecting leaks in pipes. HYDROPRESS, Inc. Nov. 30, 1950 [Jan. 20, 1950], No. 29370/50. Class 106 (2). [Also in Group XL (b)] A machine, Fig. 1, for subjecting pipes 14 to internal pressure tests between two sealing heads 27 and 22, one of which is mounted on a stationary housing 25 and the other on a movable carriage 20, comprises means for moving at least one of the sealing heads into sealing relationship with the pipe 14 by hydraulic ram and cylinder means, the movement of said head being automatically controlled by means actuated by the pipe. The machine may comprise two separate hydraulic ram and cylinder means to cause the pipe 14 and the sealing heads 27 and 22 to engage in sealing relationship. One of these may be supported on the stationary housing 25 and the other one so as to reciprocate a pipe clamping device between the stationary housing and the movable carriage. Alternatively, one of the means may be arranged on the stationary housing 25 and the other one on the movable carriage 20. One method of automatically controlling the movement of a sealing head is illustrated in Fig. 3, wherein a sealing head 29 approaches a pipe (not shown) on its right-hand side at high speed until the pipe cuts a beam of light from a source 31 passing by mirrors 32 and 33 to a photo-cell 34, the speed of the sealing head 29 is then automatically reduced by means 105 and a timer is operated to stop the movement of the sealing head 29 after a predetermined distance has been moved at this slow speed. In Fig. 4 the sealing heads 27 and 22 carry feelers 19 and 21A engaging the tube 16 under test. After the test, the sealing heads move apart until their feelers clear the tube 16 whereupon further movement is automatically stopped. If the next tube 17 is longer than the tube 16, however, a feeler 15 on the sealing head 27 contacting the tube 17 causes the sealing head 27 to continue its motion until it is sufficiently displaced to allow the tube 17 to be moved into position for testing. In the arrangement illustrated in Fig. 9, the sealing head 113 is fixed in the housing 110 but the tube to be tested is moved automatically into engagement therewith by a hydraulically operated carriage 115. The hydraulically operated sealing head 109 is then moved automatically into engagement with the tube. When the sealing heads are in engagement with the ends of the pipe, fluid pressure is automatically introduced into the pipe to test it mechanically and hydraulically for a period regulated by a timer, after which the sealing heads move apart and the pipe is removed. The Specification includes a description of an electrical circuit for initiating, controlling and timing the above functions in correct sequence. Specifications 501,665, 729,003, [both in Group XXXVII], and 729,035, [Group XXIII], are referred to.

Abstract: 206,689. Mikshel, J. J. Oct. 27, 1922. Driving machines.-In a hydraulic feed system for the tool or work in a motor-driven metal-working or like machine, a constant-volume pump 40 delivers oil by way of pipes 44, 52 from a reservoir 58, past a four-way reversing valve 45 to the right-hand end of a feed cylinder 30. The piston rod 33 is attached by means of a lug 36 to the carriage of a high-speed friction cutter such as is described in Specification 154,566, [Class 80 (iv), Mechanism &c.]. Oil from in front of the piston passes by way of pipes 55, 48 and the valve 45 back to the reservoir. A by-pass valve 75 in the circuit is opened at a limiting pressure, returning part of the oil to the reservoir. The valve is loaded by a spring 83 and its stem carries a piston 80 working in an oil dash-pot. A hand feed is provided by means of a hand-wheel 28 and a rack and pinion.

As applied to grinding a cylindrical portion on an article concentric with a portion of different diameter, the machine consists of a bed b upon which is mounted a grinding-wheel a and a slide e which may be locked by a screw k. Upon the slide e is a slide d carrying a regulating- wheel c and adapted to be locked to the slide e by a screw l, the slides being movable together, or the slide d alone being movable, by a screw m operable by a handle m<1>. The slides also are moved during grinding, after locking the screw l by a screw r, by a handle n connected to a nut rotatable in the slide d, stops o, p being provided to limit the movement of the handle n. The work is supported by a socket type of arbor s, which has a bore receiving as a running fit a machined part u<1> of the work, and is carried by a bracket f, pivoted at g to the slide e and having thereon adjustable stops h, i, of which the stop h determines the size of the work, and the stop i limits the movement of the work towards the regulating- wheel ; a spring j or a weight urges the work towards the regulating-wheel. On the support f is mounted an adjustable stop 10 which contacts with the regulating-wheel slide at 13 when the stop h, Fig. 1, is in action, this serving to prevent twisting strain on the work. In a modification, the regulating-wheel axis may be stationary and the grinding-wheel fed up to the work. The work-support may be fitted to an existing machine as an attachment thereto.

Printed copies are produced by forming a latent magnetic image on a drum 1 or band (not shown), developing the image to form a raised powder pattern, and then pressing against the image carrying surface 7 at least two sheets with a printing medium, e.g. carbon paper therebetween to obtain a printed copy of the powder pattern. A recording head 3 forms the latent image, representative of the copy to be reproduced, on the surface 7, the image being developed by a powder applicator 4. A sheet 6, e.g., of paper is passed with a sheet of carbon paper 5 between the drum 1 and a pressure roller 2. Further copies may be obtained by interposing further sheets of paper and carbon paper between the drum 1 and roller 2 and/or by transferring the powder pattern on to a paper sheet adjacent the paper 5. Alternatively, sheets 5 and 6 may be replaced by papers utilizing a chemical pressure sensitive medium.

The drum is supported in bearings 9, one of which is swingable away from the drum to provide access to one end thereof. A peripheral portion 22 of the drum is formed of elastic or resilient material having slots 26 cut therein inclined to the radius of the drum and extending helically along the drum. The parts 28 of the portion 22 outwardly of the drum expand radially during rotation of the drum to grip the sleeve 24 which is preferably of sheet steel having particles of tungsten carbide bonded to its outer surface. The particles of the bands 30 are coarser than those covering the remainder of the sleeve so that grooves are formed in a piece of wood treated by the element. The element 8 and drum 20 may be disposed between shoes 10 which have slots 12 connected to a dust extraction apparatus and press the work W against spring-pressed rollers 13, the work being fed by rollers 16, 17. A re-sawn effect can be produced on wood panels which are fed with the grain cross wise to the abrading element. A number of elements may be arranged in two staggered rows or end-to-end on a common shaft. The slots 26 permit air to pass therealong to cool the abrasive element; one end of the drum may be disposed in a pressurized zone and the other in a low pressure zone to induce air flow along the slots.

Title: Method of regenerating silica-magnesia catalysts
IPC: B01J21/20
Filed: 1949-11-24
Abstract: Spent silica-magnesia catalyst having a carbonaceous deposit thereon is, before or after the burning off of such deposits, hydrated with liquid water under suitable conditions of temperature and pressure, preferably at or below 100 DEG C. at atmospheric pressure, such that the amount of water retained by the hydrated catalyst is between 5 and 50 per cent by weight of the catalyst.  The hydration may be applied to part only of the catalyst withdrawn for example from a hydrocarbon cracking reactor, the thus hydrated catalyst mixed with the main body of withdrawn catalyst and the whole subjected to conventional burning treatment.  Alternatively, subsequent to the burning treatment on the whole of the withdrawn catalyst, part is recycled to the reactor directly whilst a portion is hydrated before being recycled.
