Title: Improvements in or relating to hydraulic dual brake systems
IPC: B60T13/10
Filed: 1969-01-16
Abstract: 1,260,421. Dual master cylinders; drivers' brake valves. STROMBERG HYDRAULIC BRAKE & COUPLING CO. 16 Jan., 1969, No. 2716/69. Heading F2F. An hydraulic dual brake system intended especially for road vehicles comprises at least one master cylinder and two separate ducts leading from that cylinder or cylinders to an auxiliary fluid control device having the spaced-apart outlets for connection to separate braking means. The auxiliary fluid control device is described below. One result of its use is that the start of pressure application to one of the brake circuits occurs before the start of pressure application to the other brake circuit, so that the pressure in the latter circuit during build-up is lower than that in the former. Furthermore, during its use, communication between the master cylinder and the brakes is interrupted.  The road vehicle hydraulic dual brake system partly shown in Fig. 1 comprises tandem master cylinders 1, 2, and ducts 4, 5, leading to inlets 6, 7, respectively of the fluid control device 8 (see also Fig. 3). When the control device 8 is idle and the master cylinders 1, 2 are operated, hydraulic fluid supplied to inlet 6 flows past an open valve 25, 27, Fig. 4, through the open end of a power piston 13, and through an outlet 11 to the front wheel brakes. Similarly, hydraulic fluid supplied to inlet 7 flows past a similar open valve 26, 28, through the open end of a floating piston 15, and through an outlet 12 to the rear wheel brakes. When the control device is operated by its pedal 19, push-rod 18 forces piston 13 to the right and with it the floating spring 14 and floating piston 15, a return spring 16 being. compressed thereby. The first result of this movement is that balls 27 and 28 lose contact with stop-pins 31, 32, Fig. 4, and move on to their respective seats 25, 26; communication between inlet 6 and outlet 11, and between inlet 7 and outlet 12, is thereby interrupted. The movement of the floating piston 15 forces hydraulic fluid out of the device 8 through outlet 12 to the rear wheel brakes. As soon as the pressure applied by the power piston 13 exceeds the resistance of the return spring 16 and the pressure generated by piston 15, floating spring 14 yields, permitting piston 13 to approach piston 15 and force hydraulic fluid out of outlet 11 to the front wheel brakes. Failure in either of the brake systems may be compensated for by excessive travel of piston 13; the necessarily-longer slot 23 in piston 13 allows for this. Floating spring 14 may be adjustably preloaded by abutting its left-hand end against the flange of a stove-pipe-shaped sleeve fitted over the adjacent end of piston 13; the sleeve is keyed to a bolt threaded into the adjacent end of piston 15, the bolt being rotatable by the sleeve to vary the pre-loading. When piston 13 approaches piston 15, the sleeve slides along the bolt (Fig. 5, not shown).

Title: Improvements in or relating to fluid-tight joints for pipes or tubes
IPC: F16L17/02
Filed: 1945-02-02
Abstract: 597,232. Pipe joints. AVEBURY, J. LUBBOCK, LORD. Feb. 2, 1945, Nos. 2731, 2732 and 2734. [Class 99 (i)] In a fluid-tight joint between pipes 1, 2, a continuous sleeve 3 of elastic material has its ends folded inwardly over the ends of a tubular expander member 4 and is housed within a casing 5 of such dimensions that it maintains the sleeve 3 under radial compression while fluid pressure in the pipes tends to jam the sleeve in the casing. In a modification, the sleeve is formed in two parts. A further modification, Fig. 3, has each of the pipes forming a T-junction provided with a separate sleeve and the expander and casing members are also of T-form. In this form, the expander members may consist of separate short tubes seated against washers located in the limbs of the casing. The third Provisional Specification refers to Specification 568,304.

Abstract: 1444202 Marine Jet Propulsion LEMOTEUR MODERNE 21 Jan 1974 [9 Feb 1973] 02791/74 Heading B7V In an under water pulse jet motor comprising a stator 1 having a segment 6 which successively closes the upstream ends of longitudinally extending ducts 4 arranged along a part helical path around the periphery of an annular rotor 3 to enable the expulsion of water from the ducts 4 by pressurised gas, an injection orifice 8 in the stator 1 adjacent the segment 6 and apertures 9 in the outer walls of the ducts 4, which successively register with the orifice 8, are located downstream from the upstream ends of the ducts so that a buffer of pressurised water 10 is formed to prevent leakage of gas at the closing segment 6 and hence improve efficiency. In the embodiment shown the pressurised gas is superheated steam from a generator 15 and a feed pump 21 driven by steam from a pipe 22 draws pressurised water from the buffer 10. To facilitate the drawing in of water into the motor, passages (not shown) may be provided to permit a flow of water from the ducts 4 to the main axial passage of the rotor within the ducts 4. In a first embodiment, conduits are formed in the segment 6 to connect the upstream ends of aligned ducts 4, and hence the buffer of water 10, to the upstream side of the main axial passage and are directed both towards the centre of the motor and downstream thereof. These conduits maybe inclined sideways in the same direction as that in which the rotor rotates (Figs. 3 and 4 not shown). Altermatively openings are formed in the inner walls of the ducts 4 at their upstream ends (Figs. 5 and 6 not shown). Finally the inner wall of the ducts may be absent over a length of the rotor at the downstream end thereof and a sector shaped plate, attached to the stator by radial fins, aligned axially with the inner wall and with the closing segment 6 is provided to close the ducts over the full length of the rotor 3 in the zone where water is ejected by pressurised gas (Figs. 7 and 8 not shown).

[A Specification was laid open to inspection under Sect. 91 of the Acts, July 27, 1934.] [Class 108 (ii)] In an independent spring-suspension for the wheels of motor-vehicles of the kind in which the stub-axle carrier a is supported and guided by a leaf-spring c preferably in combination with a pivoted link f, an additional spring e, which acts in parallel with the spring c but forms no part of the guiding means, is provided so as to furnish an auxiliary suspension in case of fracture of the spring c. In the arrangement shown, the link f is extended beyond its pivot d to form a doublearmed lever on the inner end of which acts the spring e of helical form. The steering-swivel journal g is connected to the link f through a ball joint h and to the spring c by a jointpiece i and an horizontal hinge-pin or bolt k. An additional guiding link n may be provided as described in Specification 427,578, so that, if the spring c should fracture, an auxiliary suspension linkage n, g, f remains operative. Preferably, the compression of the spring e is limited by a rubber stop s located within the spring. The invention is also applicable to suspension systems in which the leafspring c and links are arranged longitudinally.

The device may be mounted on or include a lower dividing wall 20 between the chamber 56, 58, or it may form part of an upper dividing wall 70 between the chambers. The lower edge of the gate 14 is configured so that the effective slot has a part circular boundary which is extended, when the gate 14 is in a particular position, Fig. 6 (not shown), by arcuate edge portions 36 of the wall 12. The gate 14 is slightly biased towards the lower wall 20 by a spring 24 and is guided in channels 14. The chambers 56, 58 can be evacuated independently through conduits 60, 62 and chamber 56 can also be vented independently of chamber 58. In the use of the evacuating apparatus, a receptacle, e.g. the bag 66, is positioned in the chambers 56, 58 as illustrated and the position of the gate 12 is adjusted to suit the size of the receptacle. The chamber 56 is then evacuated to cause ballooning of the receptacle and subsequently the chamber 58 is evacuated to a lower pressure than that existing in chamber 56 to cause the receptacle to collapse on to the packaged goods 64. Before evacuation of chamber 58 is terminated, the chamber 56 is vented to the atmosphere. The receptacle is gathered and clipped or heat sealed and trimmed by appropriate devices located in the chamber 56. When the package has been removed from the apparatus on a conveyer belt 74, the receptacle may be heat-shrunk.
