Title: Pure gas permeating separator assembly
IPC: C01B3/50
Filed: 1964-08-24
Abstract: A gas diffusion separation device comprises a metal membrane permeable to the gas to be purified supported on the surface of at least one supporting member having gas passages passing therethrough and terminating at said surface, the membrane having continuous or discontinuous grooves impressed therein which are in the form of concentric arcs or straight lines and the cross-section of which may be e.g. half circular, half elliptical or parabolic.  The membranes may be of silver alloy (for pure oxygen) or of molybdenum alloy (for pure nitrogen) or palladium alloy (for pure hydrogen).  As shown, the supporting members have ducts therein, but sintered metal or porcelain capable of passing gases may be employed.  In the illustrated embodiments Fig. 15 (not shown) shows a device employing a single membrane 7 which is supported on surface 2 of member 6. and pure gas permeating into the lower side of the membrane is conducted through ducts into the underlying channel and is withdrawn to the right.  The feed gas is passed through line 8 into an upper chamber above the membrane and formed by means of a member 10 which is clamped by means of bolt 11 to the lower member 6.  Unpermeated gas is withdrawn through line 9 and heating elements are provided at 12. Fig. 6 (not shown) illustrates an embodiment comprising two memranes 8 each supported on a member having ducts 6 and separated by means of a peripheral spacer 1.  Gas to be purified is introduced into the space between the two membranes and purified gas is withdrawn through ducts 6 and outlet 7.  In this case the supporting members are welded together at 9 to clamp the whole device together.  Fig. 12 (not shown) illustrates a further embodiment employing two membranes each of which is supported upon a member 5 having opposed dished surfaces 3, 4, gas to be purified being introduced through 7 into the centre of the assembly and passing outwardly to the periphery where a number of channels 6 permit it to pass into contact with the surface of the second membrane 12.  The remaining gas is removed at 8.  The purified gas passes through ducts in the supporting members leading into channels 13 and 14 and is withdrawn at 15 and 16.  Figs. 10 and 11 (not shown) illustrate associations of the devices into a stack.  The supporting surface for the membrane may be coated with a metal consisting of Cr, Mo, W, Ti, Zr, Hf, Al or an oxide thereof to prevent diffusion of the material of the membrane into the support and the peripheral part of the membrane support may be coated with one or more alloy of Au, Ag, Cu, Ni, Co or Fe to facilitate mutual diffusion of the materials.  Other alloys mentioned are palladium-silver alloys, palladium alloys containing elements of Group 8 of the Periodic Table other than palladium and elements of Group 1b of the Periodic Table and in an example an alloy containing Pd, Au, Ag and Ru is employed.

Title: Improvements relating to control apparatus for winding gear
IPC: B66D5/26
Filed: 1935-03-16
Abstract: 448,609. Brakes for winding-apparatus. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd., 1, Kingsway, London.-(Smith, D. M. ; c/o Metropolitan-Vickers Electrical Export Co., Ltd., P.O. Box 3633, Johannesburg, South Africa) March 16, 1935, No. 35263. Divided out of 448,575. [Class 78 (v)] [See also Group XXXIV] Control equipment for fluid-actuated brakes for winding-gear comprises a main control valve governed by a deceleration governor, an emergency valve arranged to cut out the main valve and cause application of the brakes independently of it, and time delay means delaying the action of the emergency valve until the expiration of a predetermined time interval from the occurrence of the emergency conditions. The cylinder of the emergency control valve 44 is connected by a pipe 43 to the cylinder of a changeover valve 40, and by pipes 46, 47, 48 to exhaust, the brake engine, and the main control valve, respectively. The plunger 39 of the valve 40 is connected by a link 38 and lever 36 to the piston 35 of a cataract cylinder 34, the outlet 32 of which is connected to trip gear 10. A solenoid 18 normally holds the plunger 16 of the trip gear in the position shown, pressure oil being supplied through the pipes 20, 32 to maintain the piston 35 in its upper position. When a trip takes place and current is cut off from the solenoid 18, the plunger 16 falls under the influence of the weight 17, and connects the cylinder 34 with exhaust through the pipe 21. Owing to the restriction 33, the piston 35 falls slowly, and takes a definite time to reach its lowest position. As the piston 35 falls, the plunger 39 rises and at a certain point cuts off the connection between the pressure fluid supply pipe 41 and the pipe 43, and puts the latter into communication with exhaust by the pipe 42. This point is varied by connecting the fulcrum 37 of the lever 36 to a cam on the depth indicator, so designed that the time lag is reduced as the bank is approached. This change-over releases the fluid contained in the space 49, and the plunger 45 descends under the influence of a spring and its weight, thereby putting the brake pipe 47 into communication with the pipe 46 and causing the application of the brakes. A recess 50 is provided in the cylinder to prevent sealing- off of the brake engine if the plunger sticks at any point during its descent. In a modification, means are provided to prevent resetting of the emergency valve after an emergency if the main control valve is in the brake-applying position. Specification 448,575 is referred to.

Abstract: 1,261,909. Conditioning chocolate. CADBURY BROS. Ltd. 17 July, 1969 [24 July, 1968], No. 35284/68. Heading A2A. [Also in Division Bl] In the manufacture of chocolate, the mixed and ground ingredients are fed to a first chamber 10, wherein work is performed on the mixture by contra-rotating helically extending paddles 16 carried by arms 15 projecting radially from two shafts 14, some of the paddles on each shaft being right-handed and some left-handed, the arrangement and pitches of the various paddles being such that considerable tumbling and cutting action is imparted to the mixture while at the same time the mixture is progressed slowly and continuously from the inlet 10a to the outlet 10b, from where it passes to a second chamber 11 containing rotating paddles 18 which are also helically arranged, at differing pitches and in differing directions, on a shaft 17 so that the mixture is further mixed and liquified, during which it progresses to outlet 11b. A further mixing and liquifying chamber may be provided which as shown comprises an inlet 12, contra-rotating shafts 19, 20 on which paddles 21 and radial arms 22 respectively are mounted, and an outlet 12b. The mixture is again progressed slowly towards the outlet 12b. This time, however, lecithin and/or cocoa butter are fed into the chamber through a second inlet 12c. The mixture discharged from the outlet 12b is then passed to a further mixing chamber (23, Fig. 1, not shown), upon discharge from which it is passed through a sieve 25 at which point it is divided into two streams, one of which is fed by a pump 26 to a storage tank, while the other, subsidiary, stream is fed by a pump 27 back to the inlet 10a of the first chamber 10. This recirculation is said to permit the viscosity of the mixture entering chamber 10 to be controlled without the addition of successive lecithin or other viscosity reducing agent to the chamber 10.

Abstract: 1,176,193. Reservoir pens. PAPER MATE MFG. CO. 4 Aug., 1967 [8 Aug., 1966], No. 35899/67. Heading B6P. Means for increasing the air pressure in an ink reservoir to cause the ink to flow towards the writing point comprises an assembly 20 insertable in the rear end of a reservoir, particularly a ball-point pen reservoir 12. The assembly 20 comprises a hollow cup-shaped adapter 22 with a port 28 in the bottom thereof, and a loosely fitting piston 50 with a stem 52 which extends through the port 28. A spring 60 biases the piston outwardly so that ears 58 formed on the stem 52 abut the rear surface 26 of the adapter. A rubber washer 70 positioned between the piston and spring 60, seals against a shoulder 40 when the piston moves inwardly, thereby compressing air in the chamber 36 of the adapter 22, which high pressure air communicate with the interior of the reservoir 12. Inward movement of the piston is limited by the shoulder 56. In an alternative embodiment (Figs. 4 and 5), the chamber 36 is defined by a compressible tubular sleeve (70a) which radially deforms to reduce the chamber volume when the piston moves radially inward. Movement of the piston 50 is achieved with the normal writing pressure exerted by the user. The reservoir 12 may be used in a non-retractable or retractable pen. With a retractable pen (Fig. 1), the retract spring (5) is weaker than spring 60. Specification 1,058,098 describes in detail the retracting mechanism shown in (Fig. 1).
