Title: Improvements in or relating to air conditioners
Inventor: VERE DUNCAN WRIGHT
IPC: F24F3/14
Filed: 1955-12-12
Abstract: 819,646. Conditioning air. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 3, 1956 [Dec. 12, 1955], No. 35574/55. Class 137 [Also in Group XIII] In an air conditioner for conditioning air to a given temperature and water content, cold air of high humidity from which water and ice are to be removed is passed through an inlet 5 into an outer chamber 1 of the conditioner whose outer walls are lagged at 2, and warm air, heated e.g. by waste or other heat from a conditioning plant, is pumped through a tube 8 is disposed centrally within the chamber. The warm air then passes out through a venturi 10 to mix with the initially cold, wet air as it passes through an outlet 6 at the upper end of the outer chamber 1. The tube 8, made of highly heat conductive material, carries on its outer surface a large number of inclined radial fins 9 which project into the chamber 1 and collect water and melted ice from the cold air stream, the moisture running down for discharge from an opening 7 formed in the bottom of the chamber 1 remote from the inlet 5. In the arrangement, Fig. 3, hot air from a vortex tube 20 passes through a cock 24 and is cooled in a heat exchanger 22. It is then fed to the tube 8, the cold air output 23 from the vortex being delivered to the inlet 5 of the chamber 1.

Title: Improvements in hydraulic transmission systems
IPC: B60T11/20
Filed: 1936-12-29
Abstract: 488,032. Hydraulic brakes. HYDRAULIC BRAKE CO. Dec. 29, 1936, No. 35646. Convention date, Dec. 30, 1935. [Class 103 (i)] [Also in Group XXIX] In a master control, suitable for operating hydraulic brakes and comprising a pair of cylinders each connected to separate fluid pressure responsive means, one cylinder has a piston adapted to apply hydraulic pressure to a second piston in the same cylinder, the second piston being connected by mechanical equalizing means to a piston in the other cylinder. A cylinder 22 has a main piston 62 operated by a pedal through rod 106 and a second piston 78 connected by a lever 88 to a piston 90 in a second cylinder 24 which is connected through a two-way valve 48 and pipe 50 to one set of brakes. The space between the pistons 62, 78 is connected through valve 32 and pipe 36 to the other set of brakes. The two sets of brakes may be the front and rear brakes of a vehicle. The piston 62 is so formed as to provide an annular chamber 68 which communicates through a port 26 with a reservoir compartment 12, the usual port 28 immediately in front of the normal position of the piston being also provided. The piston 90 is similarly formed to provide an annular chamber 94 and ports corresponding to the ports 26, 28 are also provided for connecting the chamber and cylinder to a separate compartment of the reservoir. When the piston 62 is moved liquid is forced from the space between pistons 62, 78 through pipe 36 to apply one set of brakes and at the same time pistons 78, 90 are moved by the fluid pressure in the space to force liquid from cylinder 24 through pipe 50 to the other set of brakes. During the return stroke of the pistons, if a vacuum tends to form in the cylinders liquid is drawn into them from the reservoir through the ports 26, chambers 68, 94 and ports 72, 98 in the pistons, the excess being returned through the ports 28. The relative pressures established in the two systems in a brake application may be varied by adjusting the position of the bracket 88<1> of the lever 88. If the cylinder 22 should become inoperative due to loss of liquid, pistons 78, 90 are operated by engagement of projections 76, 80 on pistons 62, 78 and if cylinder 24 becomes inoperative, piston 78 moves to the end of its stroke so that cylinder 22 remains operative.

Abstract: 1320607 Watches SUWA SEIKOSHA K K 29 July 1971 [30 July 1970] 35689/71 Heading G3T An axially movable watch stem 11 carries a winding pinion 22 which, in the inner position of the stem, co-operates with a wheel 23 which is displaceable obliquely with respect to the stem axis and is urged by a spring 31 into engagement with the winding pinion 22. The wheel 23 is supported in elongated apertures 25, 27 in bridges 26, 28 and in the inner position of the stem it meshes with a ratchet wheel 32 for winding. In this position, internal splines on the pinion 22 are engaged by splines 21 on the stem 11. If the watch has an automatic winding device which acts on the ratchet wheel 32, the wheel 23 is moved out of engagement with the pinion 22 during such winding. In an intermediate position of the stem, see Figs.2 and 6 (not shown), a calendar setting wheel 33 which is fixed to the pinion 22 is brought into engagement with a calendar ring 34. The latter may indicate the date, day, or month. The pinion 22 is still driven by the splines 21 but is out of engagement with the wheel 23. In the outer stem position, see Figs. 3 and 7 (not shown), the splines 21 are disengaged from the pinion 22 and a time setting pinion 35 which is fixed to the stem 11 engages a crown gear 36 of a setting wheel 40 The three stem positions are determined by a spring 17 having a flange 18 which co-operates with reduced diameter portions 12, 13 and 14 of the stem. On pushing the stem inwards, if the splines on the stem and the pinion 22 fail to engage, the latter and the wheel 23 may be temporarily displaced inwards against the forces of springs 43 and 31 respectively, thus avoiding damage - see Figs.4 and 8 (not shown).

Title: Apparatus and method for winding coil springs
IPC: B21F3/06
Filed: 1969-07-22
Abstract: 1,260,695. Coiling helices; making coil springs. NORTH AMERICAN ROCKWELL CORP. 22 July, 1969 [10 Oct., 1968], No. 36763/69. Headings B3A and B3E. A method of winding coil springs comprises advancing wire 13 by rollers 15, Fig. 1, at a uniform rate to an abutment surface 27, Fig. 3, where it is deflected and bent around a bending surface 23. The abutment surface 27 is movable between first and second end positions whose movement is controlled by a cam 53 having alternate first and second sets of constant radius peripheral portions, the constant radius portions being interconnected by relatively short transition portions. The surface 27 is sequentially maintained in its first end position for a first predetermined period of time, moved to its second end position during a second predetermined period of time, maintained in its second end position for a third predetermined period of time, and moved to its first end position during a fourth predetermined period of time. A single coil formed in this manner will have a first portion of relatively small constant radius formed when the surface 27 is in its first end position, a portion of relatively large constant radius formed when the surface 27 is in its second end position and portions of varying radius formed when the surface 27 is being moved to its end positions. A surface 31 is provided to longitudinally stretch the coils along the coiled axis to produce a desired pitch. In another embodiment, Fig. 7, the cam 53 is replaced by a pressure actuator 102 and valve means 103. The valve means selectively supplies pressurized fluid from a source 110 to a selected one of cylinder regions 112 and 113 so as to move the surface 27<SP>1</SP> between the two end positions. The movement of piston 107 is co-ordinated with the movement of the wire 13<SP>1</SP> by mounting a disc 116 on drive shaft 67 and locating suitable cam lobes 118 on the disc. The lobes 118 indicate formation of the various constant and variable radius portions of the coils and actuate a switch 120 which indicates to a control device 121 the formation of each coil portion.  Lobes of a disc 80, Fig. 1, mounted on the same shaft as the cam 58 actuate a switch to indicate to a control device 85 through a circuit 86 that a single coil has been formed. When the required number of coils have been formed the control device 85 actuates a brake mechanism 100 to stop the feed of the wire 13 and the reciprocation of the surface 27. The control device simultaneously actuates a fluid actuator 96 for moving a support 93 along a slide 94 so as to move shears 92 to a cutting position. Actuating mechanism 95 operates the shears to cut the wire after which the support 93 is returned to its original position.

Title: Improvements relating to thrust apparatus, and fluid pressure-operated brakes incorporating such apparatus
IPC: F16D55/40
Filed: 1956-12-06
Abstract: 845,709. Disc brakes; vehicle wheels. LAMBERT BRAKE CORPORATION. Dec. 6, 1956 [Dec. 8, 1955], No. 37371/56. Classes 103 (1) and 144 (1). In a fluid-pressure-operated piston - and - cylinder apparatus, particularly for brakes, a screw is threadedly engaged in a bore associated with the cylinder and is provided with a lost-motion connection to the piston such that the connection permits axial thrust to be imparted to the screw upon outwards movement of the piston to effect rotation of the screw to adjust its axial position but prevents counter-rotation of the screw under axial thrust imparted thereto through the connection following inwards movement of the piston through the distance corresponding to the lost-motion in the connection. In the wheel and brake assembly illustrated, a vehicle wheel 18 is mounted upon bearings 17 which are carried by the brake itself and the brake is centred on a stub-shaft 3 and is secured to the landing strut 1 of an aircraft by means of a number of pins 4 and studs 5. The brake consists of stationary annular plates 7 and 6 between which are housed fixed and rotating brake discs 26 and 25, respectively. When fluid under pressure is supplied to fluid-operated thrust-devices 34 housed in annular plate 7, the respective pistons 35 are moved outwardly to move actuator disc 27 axially towards backing-plate 12 secured to annular plate 6 against the action of brakerelease springs 31. Upon frictional engagement of the interleaved friction discs, a drag torque on the disc 25 adjacent actuation disc 27 will cause balls 30 working in inclined ramps to cam the actuator disc 27 and engage the brake with a self-energizing action. Wear of the friction surfaces is compensated for so that a constant release clearance is maintained as the respective adjuster screw 43 in each thrust device 34 is caused to shift axially along with piston 35 a distance equal to the wear to be compensated for, but are prevented from retrograde movement by virtue of resistance to opposite rotation of the screw as caused by the frictional engagement of the screw-head 46 with the end wall 47 of the piston 35. Heat generated during braking is prevented from passing to the fluid in thrust devices by a layer of insulating material of low thermal conductivity as at 53. The brake is cooled by air passing through openings 54 and 55 in the hub 9 of the stationary assembly and the backing-plate 12 is provided at its central opening 57 therethrough for the ingress of air into hub 9. Specification 665,854 is referred to.

Abstract: 1320042 Printing apparatus RICOH KK 4 Aug 1970 [13 Sept 1969] 37454/70 Heading B6C A manual control apparatus, which can be used to control an offset printing machine, comprises an angularly displaceable handle 4, which can be displaced into a plurality of discrete, e.g. click-stopped, positions 4A-4D, a slidable member 18 on the handle, at least one cam 21 or 22 and a coupling means 15 which is pivoted by the member 18 and makes a separable connection between the handle and the or each cam. Preferably there are two cams 21, 22, with slots 21a, 22a which, receive an end 15b of the coupling means, and the cams are spring-biased against a stop. The slots 21a, 22a are so shaped that when the end 15b is in a lower position it moves along their length when the handle 4 is moved, and no rotation of the cams occurs unless an end of the slot is reached, but if the member 18 is depressed and the end 15b in consequence raised, the end enters shaped recesses in the upper surfaces of the slots and, depending on the shapes of the recesses, may cause one or other of the cams 21, 22 to rotate with the handle 4. An offset printing machine may be arranged to have master plate feed means supplying a new master to plate cylinder 1 actuated by the cam 22 when it is linked to the handle 4 by depression of the member 18 and the handle is in its position 4A. Alternatively, the member 18 may be left undepressed, so that no rotation of the cam 22 occurs, and the new master plate may be applied manually. In either case movement of the handle 4 to positions 4B and 4C initiate etching of the new plate and inking and feeding of copy sheets, and the member 18 returns to its raised position before such movement is possible. After a printing run, the handle 4 is returned to its initial position, then be moved to position 4D to move cam 21 and initiate removal of the master plate and cleaning of blanket cylinder 2.

Abstract: 920,188. Centrifugal fans and compressors. SOC. ANON. DES ETABLISSEMENTS NEU. Nov. 1, 1960 [Jan. 21, 1960], No. 37543/60. Class 110(1). In the two-stage fan or compressor shown in Fig. 1, air enters the first-stage impeller 5 via an inlet casing 32 and, after leaving the first-stage volute 34, passes by way of a duct 53, right-angle bends 54, 56 and a 45 degree bend 58, Figs. 1 and 3, to the inlet casing 33 of the second stage. The air is discharged from the second-stage volute 35 through an outlet 40. Both impellers are as described in Specification 733,533, with blades passages which are constant or decrease slightly in cross-sectional area, the impeller shrouds being radially extended beyond the blades and flared at 23, 24 to form a rotary diffuser. The blades are of aerofoil form or have a cylindrical inlet part followed by a radial or nearly radial part, as described in Specification 733,533. The volutes 34, 35 provide lateral spaces 43, 44, each having a width between one and two times the outlet width of the associated rotary diffuser. The radius of curvature of each surface 46 is about one-tenth the radius of the associated rotary diffuser. The duct 53 is convergent as viewed in Fig. 1, but is divergent as viewed in a plane perpendicular to the axis of the machine to permit the cross-sectional area to remain constant. The bends 54, 56 are also of constant cross-sectional area, while the cross-sectional area of the bend 58 increases slightly. Flow disturbance at entry to each impeller is prevented by curved walls 51.
