Title: Improvements in chairs
IPC: A47C3/04
Filed: 1960-04-08
Abstract: 914,103. Nesting chairs; fixing chairs together in rows. HEIGHT, F. S. April 10, 1961 [April 8, 1960], No. 12579/60. Class 52 (2). In a chair capable of being secured side-byside with a similar chair each leg 3 is formed with a transverse upper portion 4a or 4b which when seen in plan is inclined obliquely to a line through either the front or rear pair of legs, the transverse portions 4b of one pair being inclined forwardly in relation to the upright portions of the legs and the transverse portions 4a of the other pair being inclined rearwardly, and the configuration of the transverse portions in the vertical plane on the respective sides is such that when two chairs are arranged side by side the transverse portions of one chair pass over those of the other chair and allow the legs on one side of the right-hand chair to lie directly to the left of the legs on the adjacent side of the left-hand chair. As shown in Fig. 1, the transverse portion at the top of each leg is horizontal. The transverse portions on the left-hand side of each chair are secured directly to the underside of the seat and on the right-hand side a spacer member 7 is fitted between the transverse portions and the underside of the seat. Consequently the left-hand legs are longer and the transverse portions lie at a higher level so that they may pass over the transverse portions on the right-hand side of the adjacent chair. A spacer member 18 is fitted beneath the transverse portions on the left-hand side of each chair to facilitate stacking (Fig. 3). In a modification shown in Fig. 4, the transverse portions at the tops of the legs on opposite sides of the chair terminate at the same level but have different slopes so that the transverse portions of one chair may pass over those of an adjacent chair. As shown, the transverse portions 13 on one side of the chair slope upwardly and those 12 on the other side slope downwardly from the upright portions of the respective legs 3. Alternatively, one transverse portion may be horizontal and merge into the upright portion of the leg with a gradual curvature while the other forms a relatively sharp corner with the upright portion of the leg.

[Also in Divisions G1 and H2] A submarine vessel comprises a pair of hulls 12, Figs. 1 and 2, made of resin-bonded fibreglass material, a spherical glass capsule 18 containing seats 24 for the crew, a pivoted hydrovane 46 at the forward end of the vessel and a pair of propulsion units 62 mounted on a transverse member 16 at the other end of the vessel, the hulls being furnished with valves 48 and vertical vent pipes, or stacks, 50 containing float-valves (52), Fig. 4 (not shown), whereby the interior of each hull can be flooded to reduce the buoyancy thereof. Each of the units 62 is constituted by an electric motor of the 3-phase induction type (see Division H2) the rotor 64, Fig. 7, thereof being of hollow cylindrical configuration and provided with a helical propeller-blade 69 in its interior. The capsule 18 comprises two hemispherical portions 20, 22 with steel rings 30, 32 on the edges thereof that are coupled to each other by a hinge 38 and effect sealing of the two portions relative to each other with the aid of magnetic locks 40, a folded rubber flap 36 and a rubber 0-ring (34), Fig. 8 (not shown). The motor in each of the units 62 has its stator winding 76 connected to the output sides of three amplifiers (90), Fig. 6 (not shown), which amplify signals produced by a group of photo-transistors (88) in response to light transmitted thereto through the wall of the capsule 18 from a rotatable disc (98), Figs. 8 and 9 (not shown), on a panel (92) within said capsule, the disc being either manually or automatically rotated and furnished with alternate sectors (100, 102), Fig. 10 (not shown), of reflecting and non-reflecting material, respectively. Light is directed on to the disc from lamps (110) lodged in a box 104 situated externally of the capsule and containing the transistors (88). When the disc (98) is rotated in one direction or the other, the associated motor is energized and effects propulsion of the craft either ahead or astern, accordingly. A somewhat similar arrangement is made to effect actuation of other apparatus (122), Fig. 5 (not shown), including a solenoid controlling each of the valves 48, by means of so-called switches (112, 113, 114) on each panel (92) and additional photo-transistors (112A, 113A, 114A), Fig. 11 (not shown), within the associated box (104). The hulls 12 can be discharged of water by a gas stored in bottles 126, which gas may be air, hydrogen generated by lithium hydride or one produced by liquefied hydrazine and a catalyst. A scoop 128 situated abaft the hydrovane 46 can be rotated by a motor 138 through gearing 134, 136 to deposit its contents into a basket 132. The wall of the capsule has transparent coatings (26, 28), Fig. 8, of a phenolic resin internally and externally thereof.

Abstract: 1393511 Rotary Shaft seals BORG-WARNER CORP 16 March 1973 [12 April 1972] 12692/73 Heading F2B In a mechanical seal assembly 23, Fig. 2, for a rotatable shaft sleeve 5, comprising a rotatable sealing ring 86 having a face 84 urged by the fluid pressure in the seal chamber 72 into contact with a face 85 of a non-rotatable sealing ring 74 supported by back-up means including a backing ring 80 disposed in a chamber 82, the sealing rings 74, 84 and the backing ring 80 have passages 103, 104 and 80b respectively therein through which pressure fluid is admitted from between the sealing faces to the chamber 82 and acts on the backing ring to press it against the non-rotatable ring 74. The ring 86 is urged against ring 74 by fluid pressure and by springs 101 acting through packing 93 and an expander 94 having slots 99 engaged by pins 98 on a drive ring 96. A carrier ring 88 has lugs 100 engaging the slots 99 and is keyed to the ring 86, which may be of titanium carbide. The ring 74 is prevented from rotating by keys 76 on a flange member 31 engaging slots 77 in the ring and has a face 78 in sealing contact with a face 79 on the ring 80. The chamber 80 is sealed by 0-rings 83, 83a. Ports 103 in ring 74 communicate with a circumferential groove 80a in ring 80 from which ports 80b lead to the chamber 82. Notches 104, Fig. 5, communicating with the seal housing chamber 72, extend from the outer periphery of ring 86 to a position where they at least partially intersect the ports 103 during rotation whereby a pulsating fluid pressure is admitted to the chamber 82 and acts on the backing ring 80 to apply a variable force on the ring 74 counteracting the effects of any distortion of the flange 31 in use. As shown in Fig. 2, the notches 104 have an inner edge 104a extending over about two thirds of the diameter of ports 103. In a modification, Fig. 6 (not shown), the notches end in an axially extending inner wall (204a). The assembly 23 is one stage of a staged seal arrangement, Fig. 1, for a rotary pump shaft wherein the pressure in the pump housing (not shown), is progressively reduced through seal stages 24, 23 and 22 to a low final pressure at 21 controlled by an adjustable discharge valve 42. Stage 21 is sealed by a conventional seal. Each of the stages 24, 23 and 22 is by-passed by a pressure reducing helical groove 38, 33 and 28 in flange members 36, 31 and 25 and is sealed by an assembly according to the invention.

Title: Gas chromatograph with improved shift
IPC: G01N30/46
Filed: 1961-04-10
Abstract: 946,328. Multicolumn gas chromatographs. BECKMAN INSTRUMENTS Inc. April 10, 1961 [May 12, 1960], No. 12757/61. Heading B1L. A gas chromatograph comprising at least two columns which can be connected in series, one at least of which comprises a liquid partitioning agent, a detector connected to the last column of said series and a by-pass line for one of said columns, includes a saturator containing said partitioning agent located such that when the by-pass line is switched in or out of the gas circuit, the zero readings of the detector are equalized. The saturator may be present in said by-pass line, in one of the lines connecting the by-passed column to the remainder of the chromatogaph or in the line connecting the detector to the reference carrier gas supply. As shown in Fig. 1, the carrier gas is supplied via sample inlet valve 10 to a first column 11 containing e.g. polyglycol to separate water, acetonitrile and hydrocarbons and thence through by-pass valve 12 to column 13 containing e.g. bis(2(2-methoxyethoxy)ethyl)ether to separate propane, propylene and butane and via by-pass valve 14 to the detector 15. The saturator 16 is included together with a flow restrictor 17 in the by-pass line and is loaded with the partitioning agent present in column 13 so that on switching through the by-pass line (to avoid passing the materials of higher B.P. through column 13) the partial pressure of this partitioning agent in the carrier gas is not changed. The flow restrictor 17 is adjusted so that the bypass line has the same impedance as the column 13. The saturator could equally well be located between column 11 and valve 12 or downstream of restrictor 17. In the embodiment shown in Fig. 3, the saturator 22 is loaded with the partitioning agent in column 20, e.g. paraffin oil used for separating ethane, propane and butane, it being supposed that this is absorbed by the packing in column 21, e.g. a molecular sieve for separating oxygen, nitrogen and carbon dioxide, and an optional absorber unit 25 is provided to prevent contamination of column 21 by said partitioning agent. The absorbent material may consist of activated charcoal.

As shown in Fig. 1, the seal 17 is retained in position by an indentation 22 in a metal tube 18 in the tubular extension 9, and springs 21, 23 are provided, the spring 21 being held in a cup shaped metal reinforcement 151 of the closure member 15 and the spring 23 being positioned in the tube 18. The booster is shown in its unactuated conditions with chambers on either side of the piston 3 in communication and held at low pressure. To actuate the booster a rod 7 hinged to a brake pedal is moved to the left to thereby move plunger 10 and closure member 15 until closure member 15 abuts shoulder 13 and interrupts the connection between the chambers: further movement of the plunger 10 then lifts the seat 14 off the closure member 15 and air may then enter the chamber to the right of piston 3 and move the piston 3 in the direction of braking. As shown in Fig. 2 valve spring 33 is pressed against the inside wall of extension 9 and is retained between seal 34 and the peripheral edge of a metal disc 9<SP>1</SP> in the closure member 15. Fig. 3 (not shown) illustrates a form of annular seal (37) with a radially directed edge (38).

Abstract: 695,753. Vaporizers; hand dryers. DOUGLAS, R., HARDIE-. May 16, 1952 [May 31, 1951], No. 12881/51. Classes 81 (i) and 81 (ii), [Also in Group XI] In an apparatus for producing a current of warm air mixed with a disinfecting or perfuming vapour the air is directed by a fan over an electric heating element and then over a bi-metallic strip which is distorted and lifts a valve allowing a disinfecting or perfuming fluid to be admitted to the air stream, the heat of which causes its vaporisation. The drawings show a pedestal type hand dryer consisting of an upright tubular pillar 11 lined with asbestos 12 and supported by a base 10 containing a motor driven fan. Mounted centrally in the pillar is a refractory former 13 carrying an electric heating element 14. The current to the motor and heating element is controlled by a foot pedal switch 15 so that when the pedal is depressed a stream of warm air issues from the bowl 35 at the top of the pillar over which the hands are held. The stream of warm air causes a bi-metallic strip 22 to lift a valve 24 allowing disinfecting or perfuming fluid from a'reservoir 16 to drip down a pipe 33 on to a dish 34 carried on top of the former 13, the heat causing immediate evaporation.of the fluid so that its vapour mixes with the ascending air stream.

Title: Improvements in tools for securing wires together by means of deformable clips
IPC: H01R43/045
Filed: 1957-04-23
Abstract: 841,111. Angular bending. ETABLISSEMENTS B. FAURE. April 23, 1957 [April 24, 1956], No. 12963/57. Class 83 (4). [Also in Groups XV and XXVIII] A pneumatic tool for securing wires together by wrapping a U-shaped clip 3, Fig. 5, round them, has a rod 1 with a hooked end 4, and a movable mass 2 slidable inside the tool which pushes the clips towards the hooked end and deforms them round the wires. The rod 1 has an elongated outer surface from the hooked end and the clips are inserted at a great distance from the hooked end, e.g. ten times the maximum dimension of the clips. Initially a spring 20, Fig. 1, is not compressed and a push-piece 17, 18, carried by the end of a finger 16, projects into hollow rod 1 where it has introduced a clip 3. Compressed air enters the tool through a valve 28, Fig. 2, which is opened when a rod 27, urged by a control-member 31, closes an exhaust orifice 30. Air entering tube 14, Fig. 1, through a hole 23, lifts a piston 15 upwards, compressing the spring 20 and pulling the pushpiece 17, 18 away from a passage 1b of the rod 1. When a piston 15 rises above an outlet hole 24 compressed air is admitted via a tube 26 into the rod 1 where it propels the mass 2 towards the hooked end of the rod 1. An end 2b pushes forward a clip 3, held in position by a permanent magnet 11, and bends it round the wires. A new clip 3 is now spring-urged from a magazine 13 into the path of travel of the push-piece 17, 18. As soon as the control member 31 is released, compressed air escapes through an orifice 30, then, when the piston 15 has moved down below the hole 24, through a hole 32 at the top of the cylinder 14. A spring 7 returns the mass 2 to rest position and the spring 20 returns the push-piece 17, 18, carrying a new clip 3, to its initial position. Thus, movement of the mass 2 is only possible when the push-piece 17, 18 has been moved out of the path of the mass 2. The end 17 of the push-piece is wedge-shaped so that the end one of a chain of clips may be readily detached by it. Specifications 710,616 and 841,061 are referred to.
